Syndecan-1 expression has prognostic significance in head and neck carcinoma. (1/5027)

The syndecans are a family of cell-surface heparan sulphate proteoglycans that regulate cell behaviour by binding extracellular matrix molecules such as growth factors. The syndecan family has four members, of which syndecan-1 is the most studied and best characterized. We have studied the prognostic significance of syndecan-1 expression in squamous cell carcinoma (SCC) of the head and neck treated with surgery and post-operative radiotherapy. Paraffin-embedded tissue samples taken from 175 patients with primary SCC, followed up from 2 to 15 years after surgery, were studied for expression of syndecan-1 by immunohistochemistry. A low number (< or =50%, the median value) of syndecan-1-positive tumour cells was associated with low histological grade of differentiation (P<0.0001), a large primary tumour size (T1-2 vs. T3-4, P = 0.02), positive nodal status (NO vs. N1-3, P = 0.0006), and high clinical stage (stage I or II vs. III or IV, P<0.0001). Low syndecan-1 expression was also associated with unfavourable overall survival in a univariate analysis (P = 0.001). In a multivariate survival analysis, the clinical stage and syndecan-1 expression were the only independent prognostic factors. We conclude that syndecan-1 is a novel prognostic factor in SCC of the head and neck treated with surgery and post-operative radiotherapy.  (+info)

[3H]gemcitabine uptake by nucleoside transporters in a human head and neck squamous carcinoma cell line. (2/5027)

Cellular uptake of many chemotherapeutic nucleoside analogs is dependent on the activity of a family of nucleoside transport proteins located in the cell plasma membrane. In the present study, we examined the role of these transporters in the accumulation of gemcitabine by a human head and neck squamous carcinoma cell line. The uptake of [3H]gemcitibine was compared with that of [3H]uridine and [3H]formycin B in the parent cell line (HN-5a) and in a gemcitabine-resistant variant (GEM-8e). The HN-5a and GEM-8e cells were similar in their transport characteristics and expressed predominantly the es (equilibrative, inhibitor-sensitive) transporter subtype; less than 10% of the influx of [3H]formycin B or [3H]uridine was mediated by the ei (equilibrative inhibitor-resistant) system, and there was no evidence for Na+-dependent nucleoside transporters. [3H]Gemcitabine (10 microM) entered these cells via both the es and ei transporters with an initial rate of uptake similar to that seen with the use of [3H]formycin B or [3H]uridine. In addition, ATP-replete cells accumulated significantly less [3H]gemcitabine than did ATP-depleted cells, which is indicative of an active efflux mechanism for gemcitabine. These results show that gemcitabine is a substrate for both the es and ei nucleoside transporters of HN-5a and GEM-8e cells and that gemcitabine resistance of the GEM-8e cells cannot be attributed to changes in transporter activity. Further studies to define the characteristics of the putative efflux mechanism are clearly warranted because this system has the potential to significantly affect the clinical efficacy of gemcitabine.  (+info)

Phase I study of eniluracil, a dihydropyrimidine dehydrogenase inactivator, and oral 5-fluorouracil with radiation therapy in patients with recurrent or advanced head and neck cancer. (3/5027)

5-Fluorouracil (5-FU) is an effective enhancer of radiation therapy (RT) in head and neck cancers. Due to rapid, predominantly hepatic metabolism by dihydropyrimidine dehydrogenase (DPD) and suggested clinical benefit from prolonged drug exposure, 5-FU is commonly given by continuous infusion. Eniluracil is a novel DPD-inactivator designed to prolong the half-life of 5-FU and provide sustained plasma concentrations of 5-FU with oral dosing. We conducted a Phase I study of the safety and efficacy of eniluracil given with oral 5-FU in patients receiving concurrent RT for recurrent or advanced squamous cell carcinomas of the head and neck. Thirteen patients with recurrent, metastatic, or high-risk (defined as an expected 2-year survival rate of <10%) head and neck cancer were enrolled and treated with concomitant chemoradiotherapy on an every-other-week schedule. Eniluracil at a fixed dose [20 mg twice a day (BID)] was given for 7 consecutive days (days 1-7). 5-FU and RT were given on 5 consecutive days (days 2-6). One patient was treated with once-daily RT (2.0 Gy fractions). The remaining patients received hyperfractionated RT (1.5-Gy fractions BID). The initial dose of 5-FU was 2.5 mg/m2 given BID. Dose escalation in patient cohorts was scheduled at 2.5-mg/m2 increments, with intrapatient dose escalation permitted. Lymphocyte DPD activity and serum 5-FU and uracil concentrations were monitored during two cycles. DPD activity was completely or nearly completely inactivated in all patients. Sustained, presumed therapeutic concentrations of 5-FU were observed at a dose of 5.0 mg/m2 given BID. Cumulative dose-limiting myelosuppression (both neutropenia and thrombocytopenia) was observed during the fourth and fifth cycles following administration of 5.0 mg/m2 5-FU BID. One patient died of neutropenic sepsis during cycle 4. Other late cycle toxicities included diarrhea, fatigue, and mucositis. Grade 3 mucositis was observed in 4 patients, but no grade 4 mucositis or grade 3 or 4 dermatitis was observed. A second patient death occurred during cycle 1 of treatment. No specific cause of death was identified. The study was subsequently discontinued. Cumulative myelosupression was the significant dose-limiting toxicity of oral 5-FU given with the DPD-inactivator eniluracil on an every-other-week schedule. Clinical radiation sensitization was not observed, based on the absence of dose-limiting mucositis and dermatitis. Alternative dosing schedules need to be examined to determine the most appropriate use of eniluracil and 5-FU as radiation enhancers.  (+info)

Clinical significance of decreased zeta chain expression in peripheral blood lymphocytes of patients with head and neck cancer. (4/5027)

Patients with squamous cell carcinoma of the head and neck (SCCHN) frequently have impaired immune responses. Alterations in T-cell receptor-associated signaling molecules in tumor-infiltrating as well as circulating lymphocytes have been reported in these patients. Using quantitative flow cytometry analysis, we have demonstrated that expression of the zeta chain is significantly decreased relative to normal controls in both CD8+ and CD4+ T cells as well as CD3- CD56+ CD16+ natural killer cells in the peripheral blood of patients with SCCHN who, as a result of previous therapies, have no evident disease. Patients with a more aggressive type of SCCHN and those who experienced a recurrence or had a second primary cancer within the last 2 years of the study had the lowest zeta chain expression. In addition, SCCHN patients showed a significantly greater spontaneous ex vivo apoptosis, as measured by a terminal deoxynucleotide transferase-mediated dUTP nick end labeling assay, in PBMCs, compared to normal controls. The observed decreased expression of zeta in T and natural killer cells coincided but did not directly correlate with significantly increased spontaneous apoptosis of lymphocytes obtained from treated patients with no evident disease. The results suggest that in patients with SCCHN, zeta chain defects and lymphocyte apoptosis are manifestations of long-lasting negative effects of tumor on the immune system.  (+info)

Expression of apoptosis-related genes in human head and neck squamous cell carcinomas undergoing p53-mediated programmed cell death. (5/5027)

Human head and neck squamous cell carcinoma (HNSCC) lines infected with a replication-defective Ad5CMV-p53 vector bearing a wild-type human p53 gene were used to examine alterations in the production of proteins implicated in regulating apoptosis. Because HNSCC lines express abundant levels of c-myc, and simultaneous expression of c-myc and p53 is known to trigger apoptosis in other cells, cooperation between these two genes was examined. Surprisingly, levels of c-myc mRNA and protein were rapidly and profoundly suppressed after infection with wild-type p53. Suppression of c-myc using antisense oligodeoxynucleotides (in the absence of p53) was sufficient to trigger apoptosis in Tu-138 cells, raising the possibility that the reduction of c-myc may be involved in at least one of the cell death pathways mediated by p53. Expression of a panel of Bcl-2 homology proteins was also examined in HNSCC lines undergoing p53-mediated apoptosis. No changes in Bcl-2, Bak, or Bcl-xS were found after p53 expression. Increased levels of the apoptosis-accelerating protein Bax were found in HNSCC lines after infection with Ad5CMV-p53. Induction of the apoptosis-inhibiting protein Bcl-xL was observed in Tu-167 cells and may account for the delayed onset of apoptosis in these cells. These studies suggest that multiple pathways may regulate apoptosis after transient overexpression of p53.  (+info)

The contribution of DNA ploidy to radiation sensitivity in human tumour cell lines. (6/5027)

The contribution of DNA ploidy to radiation sensitivity was investigated in a group of eight human tumour cell lines. As previous studies suggest, while more aneuploid tumours tend to be more radioresistant, there is no significant relationship between ploidy and radiation sensitivity (SF2). The failure to observe a significant effect of ploidy on radiation sensitivity is due to the complex and multifactorial basis of radiation sensitivity. When we determined the relationship between survival and radiation-induced chromosome aberration frequency, a measure independent of most other modifiers of sensitivity, we observed a direct relationship between ploidy and mean lethal aberration frequency. The mean lethal frequency of aberrations increased from about 1 for diploid cells to about 2 for tetraploid cells. The mean lethal frequency of aberrations was independent of DNA repair variations. These observations demonstrate that changes in DNA ploidy are an important contributor to radiation sensitivity variations in human tumour cell lines. Therefore, any battery of predictive assays should include DNA ploidy measurements.  (+info)

Cyclooxygenase-2 expression is up-regulated in squamous cell carcinoma of the head and neck. (7/5027)

The purpose of this study was to determine whether cyclooxygenase-2 (COX-2) was overexpressed in squamous cell carcinoma of the head and neck (HNSCC). Quantitative reverse transcription-PCR, immunoblotting, and immunohistochemistry were used to assess the expression of COX-2 in head and neck tissue. Mean levels of COX-2 mRNA were increased by nearly 150-fold in HNSCC (n = 24) compared with normal oral mucosa from healthy volunteers (n = 17). Additionally, there was about a 50-fold increase in amounts of COX-2 mRNA in normal-appearing epithelium adjacent to HNSCC (n = 10) compared with normal oral mucosa from healthy volunteers. Immunoblotting demonstrated that COX-2 protein was present in six of six cases of HNSCC but was undetectable in normal oral mucosa from healthy subjects. Immunohistochemical analysis showed that COX-2 was expressed in both HNSCC and adjacent normal-appearing epithelium. Taken together, these results suggest that COX-2 may be a target for the prevention or treatment of HNSCC.  (+info)

Quality of life in head and neck cancer patients: validation of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-H&N35. (8/5027)

PURPOSE: The aim of this study was to define the scales and test the validity, reliability, and sensitivity of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-H&N35, a questionnaire designed to assess the quality of life of head and neck (H&N) cancer patients in conjunction with the general cancer-specific EORTC QLQ-C30. PATIENTS AND METHODS: Questionnaires were given to 500 H&N cancer patients from Norway, Sweden, and the Netherlands as part of two prospective studies. The patients completed the questionnaires before, during (Norway and Sweden only), and after treatment, yielding a total of 2070 completed questionnaires. RESULTS: The compliance rate was high, and the questionnaires were well accepted by the patients. Seven scales were constructed (pain, swallowing, senses, speech, social eating, social contact, sexuality). Scales and single items were sensitive to differences between patient subgroups with relation to site, stage, or performance status. Most scales and single items were sensitive to changes, with differences of various magnitudes according to the site in question. The internal consistency, as assessed by Cronbach's alpha coefficient, varied according to assessment point and within subsamples of patients. A low overall alpha value was found for the speech and the senses scales, but values were higher in assessments of patients with laryngeal cancer and in patients with nose, sinus, and salivary gland tumors. Scales and single items in the QLQ-H&N35 seem to be more sensitive to differences between groups and changes over time than do the scales and single items in the core questionnaire. CONCLUSION: The QLQ-H&N35, in conjunction with the QLQ-C30, provides a valuable tool for the assessment of health-related quality of life in clinical studies of H&N cancer patients before, during, and after treatment with radiotherapy, surgery, or chemotherapy.  (+info)

On World Head and Neck Cancer Day held on July 27, the experts urged Indian citizens to stay away from tobacco use, as its a major cause of cancer. Head and neck cancer occurs mainly in the mouth, larynx, throat or nose.. Dr. Harit Chaturvedi, cancer surgeon, Chairman Max Oncology, and Voice of Tobacco Victims (VoTV) patron said, Head & neck cancers are the biggest sources of the cancer burden in India. Nearly half of the newly diagnosed head & neck cancers die within 12 months of diagnosis. Paradoxically, two-thirds of head & neck cancers are related to known agents such as tobacco, areca nut, and alcohol.. Unfortunately, these causative agents are freely available either due to a weak policy implementation or absence of it. India witnesses 1.75 lac new cases of head and neck cancers every year. Of these 76% are males and 24% are females.. In India, tobacco chewing is more as compared to smoking. According to the Global Adult Tobacco Survey 2017, of the 28.6% of overall prevalence of ...

Treatment with the immune-stimulating agent, Keytruda® (pembrolizumab), provides impressive long-term outcomes for some patients with metastatic or recurrent head and neck cancer. These results were recently presented at the 2016 annual meeting of the American Society of Clinical Oncology (ASCO).. Globally, head and neck cancer comprises the seventh most common type of cancer with an estimated 400,000-600,000 diagnoses every year. Head and neck squamous cell cancer (HNSCC) refers to head and neck cancer that originates in certain cells called squamous cells.. Metastatic or stage IV head and neck cancer refers to cancer that has spread from its site of origin to distant sites in the body. Overall survival at 5 years for patients diagnosed with metastatic head and neck cancer has remained at less than 4%, indicating a significant need in improved treatment for patients with this disease.

What is head/neck cancer? It is any type of cancer that originates in the cranial sinuses, the mouth, or the throat. It does not include brain tumors or thyroid tumors. Why do we need a month of awareness for this type of cancer? Head/neck cancer (HNC) is not well known. It counts for about 3-5% of all new cancer diagnoses in the USA each year. Or, about 81,000 people each year. In the big picture of things this is considered an inconsequential number of people affected. But, the effects of the cancer and the treatment to eradicate the treatment has a most consequential impact on those 81,000 people every year.. 10 years ago I was at the height of my professional career. I was on a business trip and after a late meal felt a lump in my throat. When I photographed my throat I could see the lump was a big, ugly, red, yellow and white mass.

Most types of head and neck cancer develop in the lining of cells found within many parts of the head and neck. Each year, more than 40,000 adults are diagnosed with head and neck cancer in the United States. The leading cause of this type of cancer is tobacco use. Common signs and symptoms of head and neck cancer include blood in saliva; frequent nose bleeds; and difficulty chewing, swallowing, or breathing. Effective treatments for head and neck cancer are available if the cancer is found in its early stages. However, treatment is difficult, causing many people to become depressed within 3 months of being diagnosed. Unfortunately, depression can lead to delays in treatment, impair quality of life, and decrease long-term survival. The purpose of this study is to determine whether the use of antidepressant medication initiated prior to starting treatment will prevent the onset of depression during treatment in non-depressed head and neck cancer patients. This study will also determine if ...
Introduction. Worldwide, more than 550,000 cases and 380,000 deaths occur annually from head and neck squamous cell carcinoma (HNSCC).1 In the United States, 63,000 patients are diagnosed annually, and about 13,000 die from the disease.2 The majority are related to tobacco and alcohol use, but the number of high-risk human papillomavirus (HPV)-associated oropharynx cancers is increasing; these are often identified in clinical trials via staining for the surrogate marker p16. Tumors that are p16-positive (+) have a more favorable prognosis and may require less intense treatment.3,4. Patients with HPV-associated cancers are significantly younger, have tumors typically in the tonsillar region or base of tongue, and tend to present with early-stage primary tumors with an increased risk of advanced nodal involvement when compared with HPV-negative (-) patients.5 HPV-associated tumors are pathologically distinct, with lymphocyte infiltration in the stroma and in tumor nests.6 Despite advances in ...
Background: Neurobehavioral functions and quality of life (QoL) are the important outcome measurements after radiotherapy in patients with brain tumors and even head/neck cancers. However, few studies have focused on neurobehavioral functions and QoL after anti-cancer treatment particularly brain radiotherapy for pediatric/adolescent patients with brain tumors. This study thus aims to prospectively evaluate those functions in pediatric or adolescent patients with brain or head/neck tumors in order to provide useful information about their clinical outcomes.. Methods: A total of 72 pediatric/adolescent patients, who are diagnosed with brain tumors or head/neck cancers, were prospectively recruited. Neurobehavioral functions will be evaluated using a neuropsychological battery, which includes general cognitive functions, intelligence, memory, executive functions, information processing and emotional/behavioral expressions. The QoL will be evaluated by the health-related QoL questionnaire. All ...
TY - JOUR. T1 - Non-squamous variants of human papillomavirus-related head and neck carcinoma. AU - Bishop, Justin A.. PY - 2014/1/1. Y1 - 2014/1/1. N2 - Human papillomavirus (HPV) is now well established as an important causative agent in a subset of head and neck cancers. HPV-related head and neck carcinomas are important to recognize because these malignancies are associated with better survival and an improved response to therapy when compared to their HPV-negative counterparts. HPV-related head and neck cancer characteristically takes the form of a non-keratinizing squamous cell carcinoma. Widespread HPV testing of head and neck tumours, however, has revealed variants that depart from the standard HPV-related squamous cell carcinoma morphology. Most recently, examples of HPV-related carcinomas that actually lack a squamous phenotype, at least partially, have been reported. This manuscript will discuss these non-squamous variants of HPV-related head and neck carcinomas: adenosquamous ...

Circulating interleukin-6 (IL-6) improves outcome prediction for second primary cancer (SPC) in head and neck cancer (HNC) patients. This study aimed to identify factors associated with IL-6 serum levels in HNC patients. This study was conducted as part of a phase III chemoprevention trial. IL-6 was measured using chemiluminescent immunometric assay on pretreatment serum sample obtained from 527 stage I-II HNC patients. Patients lifestyle habits, sociodemographic, medical and tumor characteristics were evaluated before radiation therapy (RT). Factors independently associated with IL-6 levels before RT were identified using multiple linear regression. The median IL-6 serum level was 3.1 ng/L. In the multivariate analysis, eight factors were significantly associated (p | 0.05) with IL-6: age, gender, marital status, body mass index, tobacco consumption, comorbidities, Karnofsky Performance Status and HNC site. Smoking duration and lifetime pack-years were positively associated with IL-6 serum levels in

Head and neck cancers are a group of biologically similar cancers originating from the upper aerodigestive tract, including the lip, mouth, nasal cavity, paranasal sinuses, pharynx and larynx that affect more than 45,000 individuals in the U.S. each year. Head and neck cancers are strongly associated with environmental and lifestyle risk factors, including tobacco smoking, alcohol consumption and certain strains of the sexually transmitted human papilloma virus.. Founded in 1984, the University of Pittsburgh Cancer Institute became a National Cancer Institute (NCI)-designated Comprehensive Cancer Center in six years. UPCI is the only cancer center in western Pennsylvania with this elite designation, serving the regions population of more than 6 million. Presently, UPCI receives a total of $154 million in research grants and is ranked 10th in NCI funding.. ...
Systemic treatment of head and neck squamous cell carcinoma (HNSCC) includes a variety of antineoplastic drugs. However, drug-resistance interferes with the effectiveness of chemotherapy. Preclinical testing models are needed in order to develop approaches to overcome chemoresistance. Ten human cell lines were obtained from HNSCC, including one with experimentally-induced cisplatin resistance. Inhibition of cell growth by seven chemotherapeutic agents (cisplatin, carboplatin, 5- fluorouracil, methotrexate, bleomycin, vincristin, and paclitaxel) was measured using metabolic MTT-uptake assay and correlated to clinically-achievable plasma concentrations. All drugs inhibited cell growth in a concentration-dependent manner with an IC50 comparable to that achievable in vivo. However, response curves for methotrexate were unsatisfactory and for paclitaxel, the solubilizer cremophor EL was toxic. Cross-resistance was observed between cisplatin and carboplatin. Chemosensitivity of HNSCC cell lines can be
Exposure to tobacco-specific nitrosamines (TSNA) and polycyclic aromatic hydrocarbons (PAH) is recognized to play an important role in the development of oral/head and neck squamous cell cancer (HNSCC). We recently reported higher levels of TSNA-associated DNA adducts in the oral cells of smokers with HNSCC as compared with cancer-free smokers. In this study, we further investigated the tobacco constituent exposures in the same smokers to better understand the potential causes for the elevated oral DNA damage in smokers with HNSCC. Subjects included cigarette smokers with HNSCC (cases, n = 30) and cancer-free smokers (controls, n = 35). At recruitment, tobacco/alcohol use questionnaires were completed, and urine and oral cell samples were obtained. Analysis of urinary 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and N-Nitrosonornicotine (NNN; TSNA biomarkers), 1-hydroxypyrene (1-HOP, a PAH), cotinine, 3′-hydroxycotinine, and the nicotine metabolite ratio (NMR) were performed.

Every year, more than 17,000 people in Germany are diagnosed with head and neck cancers. These include cancers of the oral cavity, larynx and nose, but can also affect other areas of the head and neck. Some head and neck cancer patients will also develop lung cancer. In the large majority of cases, it is impossible to determine whether these represent pulmonary metastases of the patients head and neck cancer or a second primary cancer, i.e. primary lung cancer, explains Prof. Dr. Frederick Klauschen of Charités Institute of Pathology, who co-led the study alongside Prof. Dr. David Capper of Charités Department of Neuropathology. This distinction is hugely important in the treatment of people affected by these cancers, emphasizes Prof. Klauschen, adding: While surgery may provide a cure in patients with localized lung cancers, patients with metastatic head and neck cancers fare significantly worse in terms of survival and will require treatments such as chemoradiotherapy ...

Head and neck cancer is a group of cancers that starts within the mouth, nose, throat, larynx, sinuses, or salivary glands. Symptoms may include a lump or sore that does not heal, a sore throat that does not go away, trouble swallowing, or a change in the voice. There may also be unusual bleeding, facial swelling, or trouble breathing. About 75% of head and neck cancer is due to the use of alcohol or tobacco. Other risk factors include betel quid, certain types of human papillomavirus, radiation exposure, certain workplace exposures, and Epstein-Barr virus. Head and neck cancers are most commonly of the squamous cell carcinoma type. The diagnosis is confirmed by tissue biopsy. The degree of spread may be determined by medical imaging and blood tests. Not using tobacco or alcohol can reduce the risk. While screening in the general population does not appear to be useful, screening high risk groups by examination of the throat might be useful. Often, head and neck cancer is curable if detected ...
Conference report on the Indo Global Summit on Head and Neck Oncology (IGSHNO 2017-BMCON-IV), 24-26 February 2017, Jaipur, India Tej Prakash Soni,
Decisions about treatment for head and neck cancer are largely dependent on the site, stage, and histological characteristics of the disease. Treatment may include surgery, RT, chemotherapy, or some combination of these. RT is offered to nearly 75 percent of patients with head and neck cancer with curative or palliative intent, often with long-term side effects.. RT techniques have evolved over the past 30 years; two-dimensional images have been replaced with three-dimensional (3D) images with the intended purpose of improving effectiveness while reducing toxicity to normal tissues and adjacent vulnerable organs. Photon-based conformal external-beam RT modalities used to treat head and neck cancer include 3D conformal RT (3DCRT), intensity-modulated RT (IMRT), and stereotactic body RT (SBRT). Charged particle-based conformal external-beam RT modalities, such as proton-beam RT (PBT), are also available to treat head and neck cancer, although they are not widely available in the United ...
Objective: Head and Neck Squamous Cell Carcinoma (HNSCC) is the fifth most common cancer worldwide with five-year survival rate of 50% despite use of modern treatment modalities. We have employed a comprehensive genome-wide integrated analysis of epigenetic and transcriptional alteration in primary HNSCC tissues in order to discover novel biomarkers of this disease.. Experimental Design: A discovery cohort included 44 primary HNSCC and 25 normal mucosal samples was analyzed by Affymetrix GeneChip Human Exon 1.0 and Illumina Infinium Human Methylation 27 arrays. An independent validation cohort included 32 primary HNSCC and 15 normal mucosal samples to confirm differential methylation by bisulfate sequencing. A second validation cohort included salivary rinse and primary tissue from 59 HNSCC and 31 healthy patients. Detection of DNA methylation in bodily fluids and primary tissues from the later cohort was evaluated by quantitative methylation-specific PCR (qMSP).. Results: We have applied novel ...

Patients were age- and sex-matched in a 1:10 ratio with general population controls. Uni- and multivariate analyses were performed using the Cox regression model to assess the correlation between STD and HNC.Results: A total of 39,405 HNC patients (63% men; 63.0 years at HNC diagnosis) and 393,238 controls were included. STD in HNC patients was 0.27%, vs. 0.11% in controls. Patients with cancer of the upper airways had a significantly higher prevalence of an STD prior to the HNC compared to controls. Most HNC patients with a prior STD (64.1%) developed the HNC within five years after the STD diagnosis.Conclusions: ...

The two strongest risk factors for these cancers are excessive alcohol use and tobacco use. At least 75 percent of head and neck cancers are related to alcohol and tobacco use, and people who drink excessively and use tobacco - whether smoked or chewed - are at even greater risk than those who use either tobacco or alcohol alone. ...
TY - JOUR. T1 - Role of twist in head and neck carcinoma with lymph node metastasis. AU - Ou, Da Liang. AU - Chien, Hsiung Fei. AU - Chen, Chi Long. AU - Lin, Tsung Chin. AU - Lin, Liang In. PY - 2008/3. Y1 - 2008/3. N2 - The transcription factor Twist protein has been found to be correlated with metastasis in various carcinomas, including hepatocellular, breast and prostate carcinomas. However, the role of Twist in head and neck squamous cell carcinomas (HNSCC) remains unknown. Head and neck cancer tissue microarrays (TMAs) of tumors from 50 patients with HNSCC were examined. Immunohistochemical (IHC) stain analysis showed that, out of the 50 patients, twenty (40%) showed Twist-positive staining in the tumor cells, and Twist expression was positively associated with differentiation status (p=0.027), lymph node metastasis (p=0.032) and disease progression (p=0.029). Further analysis revealed that the expression of Twist was positively correlated with CXCR4 (Spearman, r=0.408, p=0.003) and CCR7 ...
The biggest risk factors for head and neck cancers are tobacco (both cigarettes and chewing tobacco) and alcohol, especially when used together.
Tumors of the head and neck present aggressive pathological behavior in patients due to high expression of CDK/CCND1 proteins. P276-00, a novel CDK inhibitor currently being tested in clinic, inhibits growth of several cancers in vitro and in vivo. The pre clinical activity of P276-00 in head and neck cancer and its potential mechanisms of action at molecular level are the focus of the current studies. We have investigated the anti-cancer activity of P276-00 in head and neck tumors in vitro and in vivo. Candidate gene expression profiling and cell based proteomic approaches were taken to understand the pathways affected by P276-00 treatment. It was observed that P276-00 is cytotoxic across various HNSCC cell lines with an IC50 ranging from 1.0-1.5 μmoles/L and culminated in significant cell-cycle arrest in G1/S phase followed by apoptosis. P276-00 treatment suppressed cell proliferation through inhibition of CCND1 expression, reduced phosphorylation of retinoblastoma protein and abrogative
Squamous cell carcinoma of the head and neck (SCCHN) cells can escape recognition and lysis by tumor antigen (TA)-specific cytotoxic T lymphocytes (CTL) by downregulation of antigen processing machinery (APM) components, such as the transporter associated with antigen processing (TAP)-1/2 heterodimer. APM component upregulation by interferon gamma (IFN-g) restores SCCHN cell susceptibility to lysis by CTL, but the mechanism underlying TAP1/2 downregulation in SCCHN cells is not known. Because IFN-g activates signal transducer and activator of transcription (STAT)-1, we investigated phosphorylated (p)-STAT1 as a mediator of low basal TAP1/2 expression in SCCHN cells. SCCHN cells were found to express basal total STAT1 but low to undetectable levels of pSTAT1. The association of increased pSTAT1 levels and APM components likely reflects a cause-effect relationship, since STAT1 knockdown significantly reduced both IFN-g-mediated APM component expression and TA-specific CTL recognition of IFN-g ...

According to an article recently published in the Archives of Otolargynology - Head and Neck Surgery, patients with head and neck cancer who are undergoing chemotherapy and radiation therapy have high rates of impaired ability to swallow, causing them to suck food or liquid particles through their vocal cords (aspiration).. Head and neck cancers originate in the oral cavity (lip, mouth, and tongue), salivary glands, paranasal sinuses, and nasal cavity, pharynx (upper back part of the throat), larynx (voice box), and lymph nodes in the upper part of the neck. Worldwide, head and neck cancer is diagnosed in approximately 640,000 people annually and is responsible for approximately 350,000 deaths each year.. Chemotherapy and radiation therapy are common treatment approaches for patients with head and neck cancer. These treatments are, however, associated with side effects, some of which impair ability to swallow. When swallowing is impaired, there is a risk of aspiration, often thought of as food ...
First-line treatment with Keytruda significantly prolongs survival of patients with recurrent or metastatic head and neck squamous cell carcinoma
Head and neck cancer refers to tumors that occur in the lining of the nose, mouth (oral cancer) or throat, as well as cancers of the thyroid, parathyroid and salivary glands. Doctors also include advanced skin cancers of the head and neck (scalp, ears, face and neck) in this category of cancers. ...
Affymetrix U133plus2 GeneChips were used to profile 59 head and neck squamous cell cancers. A hypoxia metagene was obtained by analysis of genes whose in vivo expression clustered with the expression of 10 well-known hypoxia-regulated genes (e.g., CA9, GLUT1, and VEGF). To minimize random aggregation, strongly correlated up-regulated genes appearing in |50% of clusters defined a signature comprising 99 genes, of which 27% were previously known to be hypoxia associated. The median RNA expression of the 99 genes in the signature was an independent prognostic factor for recurrence-free survival in a publicly available head and neck cancer data set, outdoing the original intrinsic classifier. In a published breast cancer series, the hypoxia signature was a significant prognostic factor for overall survival independent of clinicopathologic risk factors and a trained profile. The work highlights the validity and potential of using data from analysis of in vitro stress pathways for deriving a biological

Two phase III clinical trials (CheckMate 141 and KEYNOTE 040) have independently demonstrated that overall survival (OS) in recurrent and/or metastatic head and neck squamous cell carcinoma (R/M HNSCC) patients, who have failed platinum-based therapy, can be improved with anti-PD1 monotherapy. Treatment with nivolumab or pembrolizumab in R/M HNSCC patients led to an improved OS with a hazards ratio (HR) of 0.70 (95%CI 0.51-0.96; p = 0.01) and HR of 0.80 (95%CI 0.65-0.98, p = 0.0161), respectively, as compared to standard of care (SOC) chemo monotherapy regimens (specifically, cetuximab, docetaxel, or methotrexate). The gain in OS was similar in both studies, underscoring the role of anti-PD1 drugs in R/M HNSCC patients. One of the striking discrepancies between CheckMate 141 and KEYNOTE 040 was the OS observed in the control SOC arms (6.9 months median in KEYNOTE 040 versus 5.1 months in CheckMate 141), which inadvertently set a higher threshold in the bio-statistical analysis of KEYNOTE 040 so that the
Pathology Department, Harvard Medical School, Boston, Massachusetts 02115-5701, USA. We have investigated the functional integrity of the retinoblastoma tumor suppressor pathway in five human squamous cell carcinoma lines. Elevated activity of cyclin-dependent kinase 6 (cdk6), a pRB kinase, was detected in all five squamous cell carcinoma lines. Overexpression of the cdk6 protein was detected in one of the five cell lines. The cdk6-specific inhibitor p18ink4C is expressed and associated with cdk6 in all five squamous cell carcinoma lines. In contrast, only very low levels of p16ink4A were detected in these cell lines. This may contribute to the elevated activity of cdk6 in these lines. Elevated activity of cdk6 may result in hyperphosphorylation of the retinoblastoma protein and, therefore, compromise its negative growth-regulatory activity ...

Reactive oxygen species (ROS) produced as a part of cellular metabolism can interact with biological macromolecules such as DNA, proteins and lipids and interfere with their normal functions, leading to the loss of cellular viability. ROS have been implicated in many pathophysiological conditions including cancer. In the present study, the damage caused by ROS and the effect of radiation in head and neck squamous cell carcinoma (HNSCC) patients were assessed in the erythrocytes by analyzing the superoxide dismutase (SOD) and catalase (CAT) activities, and levels of total thiols (T-SH) and malondialdehyde (MDA, a marker for lipid peroxidation). Blood samples were collected before the start of treatment and after the completion of radiotherapy. Both SOD and CAT activities were decreased in untreated patients, but elevated in patients after treatment. The T-SH levels were also depleted in untreated HNSCC patients, but elevated non-significantly after radiation therapy (p>0.05). The levels of MDA ...
Recurrent squamous cell carcinoma of the skin treated successfully with single agent cetuximab therapy Selcuk Seber,1 Aylin Gonultas,2 Ozlem Ozturk,2 Tarkan Yetisyigit1 1Department of Medical Oncology, Faculty of Medicine, Namik Kemal University, 2Pathology Department, Tekirdag State Hospital, Tekirdag, Turkey Abstract: Recurrent squamous cell carcinoma of the skin is a rare but difficult to treat condition. Frequently, the disease presents itself in elderly patients with poor performance status and bearing many comorbidities, thus the decision to administer systemic chemotherapy becomes difficult to make. In addition, current chemotherapeutic protocols response rates are far from satisfactory. Recently cetuximab, a chimeric antibody against epidermal growth factor receptor, is increasingly being reported as an alternative treatment. We therefore report this case of a recurrent squamous cell carcinoma of the skin in an elderly woman with poor performance status and who had an excellent clinical

ISSN 2078-5151. http://dx.doi.org/10.7196/SAJS.1357.. OBJECTIVES/HYPOTHESIS: The objective of the study was to determine whether sentinel lymph node biopsy (SLNB) can be used to reduce clinical overstaging of cervical nodes in head and neck squamous cell carcinoma (SCC) in a developing world setting. STUDY DESIGN: Sentinel and echelon lymph nodes were identified by means of a combination of lymphoscintigraphy, gamma probe and blue dye staining. They were analysed histologically and their pathological status was compared with the rest of the neck dissection specimen to determine diagnostic accuracy in patients with T1-4 N0-3 SCC of the oral cavity or oropharynx undergoing primary surgical resection and neck dissection. RESULTS: Thirty-three patients were included in the study, 13 in the node-negative (N0) and ...
Fifty-two Head and Neck Cancer societies and forty-five countries have declared July 27 to be International Head and Neck Cancer Day. Head and neck cancer is the leading cause of cancer-related deaths and disability in many parts of the world. Head and neck cancers include mouth and throat cancer, thyroid, skin cancers of the head and neck and the new epidemic HPV-induced oropharynx cancers.. In support of International Head and Neck Cancer Day, The Dobleman Head and Neck Cancer Institute, will be raising awareness of these diseases by hosting a Golf-A-Thon. Our annual golf-a-thon is typically held the last week of July. Specific dates will be announced at the beginning of 2017. All proceeds from this event will be used for community-based prevention and early detection by providing free head and neck cancer screenings and education, CEU course for healthcare providers, a Creighton University IPE program for dental and medical students and research..

It has been suggested that ESAs might improve treatment outcome by reducing tumour hypoxia, but ESAs might also increase tumour growth. In this work, the effect of recombinant human erythropoietin (rHuEpo) beta was investigated on a human head and neck squamous carcinoma cell (HNSCC) line in vitro. The cell line was previously growth stimulated in combination with surgery in a xenograft model and the investigation was initiated to see if rHuEpo directly affects the tumour cell line, alone or in combination with cell stress, or if the in vivo effect should be attributed to secondary effects. Material and methods. The cell line LU-HNSCC-7 was grown in vitro and treated with rHuEpo alone or in combination with radiation, cisplatin, hypoxia or tumour extracts. The expression of the Epo receptor (EpoR) was investigated by western blotting ...

Infection with high-risk types of human papilloma virus (HPV) is currently the best-established prognostic marker for head and neck squamous cell carcinoma (HNSCC), one of the most common and lethal human malignancies worldwide. Clinical trials have been launched to address the concept of treatment de-escalation for HPV-positive HNSCC with the final aim to reduce treatment related toxicity and debilitating long-term impacts on the quality of life. However, HPV-related tumors are mainly restricted to oropharyngeal SCC (OPSCC) and there is an urgent need to establish reliable biomarkers for all patients at high risk for treatment failure. A patient cohort (n = 295) with mainly non-OPSCC (72.9%) and a low prevalence of HPV16-related tumors (8.8%) was analyzed by MassARRAY to determine a previously established prognostic methylation score (MS). Kaplan-Meier revealed a highly significant correlation between a high MS and a favorable survival for OPSCC (P = 0.0004) and for non-OPSCC (P,0.0001), which ...
The immune landscape of head and neck squamous cell carcinoma in pretreated areas remains poorly documented. We aimed to assess the tumor microenvironment for biomarkers of antitumor immune responses in tumors in previously irradiated areas compared with de novo tumors. This retrospective monocentric study analyzed 100 paraffin‑embedded surgical samples of invasive head and neck squamous cell carcinoma (oral cavity, oropharynx, larynx, hypopharynx) from patients who underwent surgery between January 2010 and November 2017. We compared the immune microenvironment in 50 de novo tumors and 50 tumors recurring within irradiated areas. We used immunohistochemistry to assess p16 status, CD3+/CD8+ tumor‑infiltrating lymphocytes (TILs), and programmed death‑ligand 1 (PD‑L1) expression on tumor and immune cells in stromal and intratumoral components. CD3+ TIL counts were significantly lower in intratumoral and stromal components (P=0.003 and P=0.020, respectively) in the irradiated area cohort; ...
Background: Squamous cell carcinomas (SCCs) are common head and neck malignancies demonstrating lymph node LN involvement. Recently chemokine receptor overxpression has been reported in many cancers. Of particular interest, CCR7 appears to be a strong mediator of LN metastases, while CXCR4 may mediate distant metastases. Any relations between their expression in primary HNSCCs and metastatic lymph nodes need to be clarified. Aims: To investigate CCR7 andCXCR4 expression in primary HNSCCs of all tumor sizes, clinical stages and histological grades, as well as involved lymph nodes, then make comparisons, also with control normal oral epithelium. Materials and Methods: The sample consisted of 60 formalin-fixed, paraffin-embedded specimens of primary HNSCCs, 77 others of metastasi-positive lymph nodes, and 10 of control normal oral epithelial tissues. Sections were conventionally stained with H&E and immunohistochemically with monoclonal anti-CCR7 and monoclonal anti-CXCR4 antibodies. Positive cells were

Lately, the incidence of human papillomavirus (HPV)-related tumors has shown a significant increase, and HPV-related tumors show distinctive features if compared with the HPV-negative counterpart. Locally advanced HNSCC can be treated with concomitant chemoradiotherapy, but early recurrences sometimes occur. Relapses are often related to an intrinsic radioresistance of the tumors. Alterations in intracellular pathways, primarily involved in cell proliferation, apoptosis, and DNA repair, can lead to radioresistance. Preclinical and clinical evidence highlighted ...
Twenty-one head and neck squamous cell carcinoma (HNSCC) cell lines were established from 89 fresh tumor specimens in order to study the biology of HNSCC lines, establish tumors in nude mice, and evaluate the sensitivity to immunological effector cells of these tumors in vitro and in vivo in nude mice. The lines were established from explants using differential trypsinization and culture for 2 to 20 mo. The explants were derived from 11 different sites. Three pairs of lines were derived from both the primary tumor and metastatic lymph nodes in the same patients. All cultures grew as either compact or diffuse adherent monolayers, and they had a median doubling time of 86 h (range, 33 to 531 h). DNA fingerprinting confirmed that the HNSCC lines were individual isolates. Thirteen of 14 lines tested induced tumors in athymic mice. The histology of each line growing in nude mice was similar to that of the original tumor tissue. Immunocytochemistry showed keratin production in all lines tested. ...

Head and neck cancer accounts for approximately 6% of diagnosed malignancies in the United States, with an estimated 35,000 incidences and over 7,000 deaths every year. Head and neck squamous cell carcinoma (HNSCC) comprises the majority of head and neck cancers, with a worldwide incidence of more than 500,000 cases. Head and neck cancer patients often present in advanced stages of disease, and despite ongoing research, survival rates remain lower than other more common malignancies. Cytokines and pro-inflammatory factors have been shown to have a critical role in the various steps of malignant transformation, including tumor growth, survival, invasion, angiogenesis, and metastasis. Mitogen-activated protein kinases (MAPK), such as p38, JNK, and ERK, relay information from extracellular signals to the effectors that control these diverse cellular processes. Negative regulation of MAPK activity is provided by MAPK phosphatases that dephosphorylate MAPK proteins. The founding member of this class ...

The presence of metastatic disease in cervical lymph nodes of head and neck squamous cell carcinoma (HNSCC) patients is a very important determinant in therapy choice and prognosis, with great impact in overall survival. Frequently, routine lymph node staging cannot detect occult metastases and the post-surgical histologic evaluation of resected lymph nodes is not sensitive in detecting small metastatic deposits. Molecular markers based on tissue-specific microRNA expression are alternative accurate diagnostic markers. Herein, we evaluated the feasibility of using the expression of microRNAs to detect metastatic cells in formalin-fixed paraffin-embedded (FFPE) lymph nodes and in fine-needle aspiration (FNA) biopsies of HNSCC patients. An initial screening compared the expression of 667 microRNAs in a discovery set comprised by metastatic and non-metastatic lymph nodes from HNSCC patients. The most differentially expressed microRNAs were validated by qRT-PCR in two independent cohorts: i) 48 FFPE lymph
These data suggest that pembrolizumab plus cetuximab may have promising activity for platinum-refractory or -ineligible patients with recurrent or metastatic head and neck squamous cell carcinoma, said Assuntina G. Sacco, MD, Associate Professor of Medicine and Medical Director of Infusion Services at UC San Diego Moores Cancer Center, La Jolla, California. The safety profile was also acceptable, resulting in few treatment-related discontinuations. Ongoing and future studies of combined anti-PD-1 and EGFR inhibition are indicated.. As Dr. Sacco reported, it is well established that patients with recurrent or metastatic head and neck squamous cell carcinoma who are either platinum-refractory or -ineligible have poor survival outcomes.

Head and neck squamous cell carcinoma (HNSCC) is an aggressive disease marked by frequent recurrence and metastasis and stagnant survival rates. To enhance molecular knowledge of HNSCC and define a non-coding RNA (ncRNA) landscape of the disease, researchers at UCSD profiled the transcriptome-wide dysregulation of long non-coding RNA (lncRNA), microRNA (miRNA), and PIWI-interacting RNA (piRNA) using RNA sequencing data from 422 HNSCC patients in The Cancer Genome Atlas (TCGA). 307non-coding transcripts differentially expressed in HNSCC were significantly correlated with patient survival, and associated with mutations in TP53, CDKN2A, CASP8, PRDM9,and FBXW7 and copy number variations in chromosomes 3, 5, 7, and 18. The researchers also observed widespread ncRNA correlation to concurrent TP53 and chromosome 3p loss, a compelling predictor of poor prognosis in HNSCCs. Three selected ncRNAs were additionally associated with tumor stage, HPV status, and other clinical characteristics, and modulation ...
In an Indian phase III trial reported in the Journal of Clinical Oncology, Vanita Noronha, MD, of Tata Memorial Hospital, Mumbai, and colleagues found that curative-intent adjuvant chemoradiation with cisplatin at 100 mg/m2 every 3 weeks produced better locoregional control vs cisplatin at 30 mg/m2 every week in patients with locally advanced head and neck squamous cell cancer.1 Severe adverse events were more common in the every-3-week group.. Study Details. In the noninferiority trial, 300 patients with locally advanced head and neck cancer at Tata Memorial Center in Mumbai were randomized between 2013 and 2017 to receive cisplatin at 30 mg/ m2 given once a week (n = 150) vs cisplatin at 100 mg/m2 given once every 3 weeks (n = 150), both administered concurrently with curative-intent radiotherapy. Disease had to be locally advanced with no distant metastases with planned curative chemoradiation, either as adjuvant treatment for ≥ 1 high-risk feature (eg, extracapsular extension, close [≤ 5 ...
Head and neck squamous cell carcinoma (HNSCC) is one of the most common types of human cancer and frequently metastasizes to LNs. Identifying metastasis-promoting factors is of immense clinical interest, as the prognosis for patients with even a single unilateral LN metastasis is extremely poor. Here, we report that p90 ribosomal S6 kinase 2 (RSK2) promotes human HNSCC cell invasion and metastasis. We determined that RSK2 was overexpressed and activated in highly invasive HNSCC cell lines compared with poorly invasive cell lines. Expression of RSK2 also correlated with metastatic progression in patients with HNSCC. Ectopic expression of RSK2 substantially enhanced the invasive capacity of HNSCC cells, while inhibition of RSK2 activity led to marked attenuation of invasion in vitro. Additionally, shRNA knockdown of RSK2 substantially reduced the invasive and metastatic potential of HNSCC cells in vitro and in vivo in a xenograft mouse model, respectively. Mechanistically, we determined that ...

Human Papilloma Virus Attributable Head and Neck Cancer in the Sudan Assessed by p16INK4A Immunostaining Head and neck cancer;human papillomavirus;$p16^{INK4A}$;Sudan; Background: The aim of this study was to screen for human papillomavirus (HPV) infections in head and neck squamous cell carcinomas (HNSCCs) using P16 immunostaining. Materials and Methods: A retrospective study was performed on 150 samples from patients diagnosed with HNSCCs. HPV status was determined using $p16^{INK4A}$. Results: 31 of the 150 (20.7%) HNSCCs were HPV positive. Conclusions: A large proportion of HNSCCs in Sudan are associated with HPV infection. The fact that the prevalence of HPV is high among Sudanese patients with head and neck cancers (HNC) has obvious implications for vaccine therapy.

Metformin is commonly used for treating type 2 diabetes, and may also reduce cancer risk. Previous studies have demonstrated the association between metformin use and a decreased risk of head and neck cancer. Therefore, the aim of the present systematic review was to summarize the available literature on the in vitro anti‑tumor effects of metformin on head and neck squamous cell carcinoma (HNSCC). Research studies were obtained from Cochrane Library, Embase, LILACS, MEDLINE and PubMed databases, without time or language restrictions. Only in vitro studies analyzing the effects of metformin on HNSCC cell lines were included. The authors methodically appraised all the selected studies according to the Grading of Recommendations Assessment, Development and Evaluation method to make a judgment of the evidence quality. Of the 388 identified reports, 11 studies met the inclusion criteria and were used for qualitative analysis. These studies demonstrated that metformin is important in inhibiting cell ...
Head and neck squamous cell carcinoma (HNSCC) represents a major health concern worldwide. We applied the matrix-assisted laser desorption/ionization (MALDI) imaging mass spectrometry (IMS) to analyze paired normal (N) and tumor (T) samples from head and neck squamous cell carcinoma as well as liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis in HNSCC cell lines to identify tumor-associated biomarkers. Our results showed a number of proteins found to be over-expressed in HNSCC. We identified thymosin beta-4 X-linked (TMSB4X) is one of the most significant candidate biomarkers. Higher TMSB4X expression in the tumor was found by N/T-paired HNSCC samples at both RNA and protein level. Overexpression of TMSB4X was found significantly associated with poor prognosis of overall survival (OS, P = 0.006) and recurrence-free survival (RFS, P = 0.013) in HNSCC patients. Silencing of TMSB4X expression in HNSCC cell line reduced the proliferation and invasion ability in vitro, as well ...
The role of c-erbB receptors and ligands in head and neck squamous cell carcinoma. c-erbB receptor signalling induces pleiotropic responses and influences several biological functions involved in the pathogenesis and progression of HNSCC. Aberrant expression of multiple c-erbB receptors and ligands is frequently observed in tumour cells. EGFR appears to be a dominant factor controlling the malignant phenotype in HNSCC at least in part via regulation of molecules involved in invasive and angio-/lymphangiogenic processes. Although c-erbB-2 is an orphan receptor, the formation of heterodimer complexes appears to be an important mechanism for inter-receptor activation and synergistic signal transduction. The roles of c-erbB-3 and c-erbB-4 in HNSCC progression are less clear. However, their ability to form heterodimers with other c-erbB family members enhances proliferation and invasion in HNSCC cells. At least two major downstream signalling pathways, MAPK and PI3K, are involved in the ...
Despite advances in diagnostic and treatment strategies, head and neck squamous cell cancer (HNSCC) constitutes one of the worst cancer types in terms of prognosis. PTEN is one of the tumour suppressors whose expression and/or activity have been found to be reduced in HNSCC, with rather low rates of mutations within the PTEN gene (6-8%). We reasoned that low expression levels of PTEN might be due to a transcriptional repression governed by an oncogene. Tbx2 and Tbx3, both of which are transcriptional repressors, have been found to be amplified or over-expressed in various cancer types. Thus, we hypothesize that Tbx3 may be over expressed in HNSCC and may repress PTEN, thus leading to cancer formation and/or progression. Using immunohistochemistry and quantitative PCR (qPCR), protein and mRNA levels of PTEN and Tbx3 were identified in samples excised from cancerous and adjacent normal tissues from 33 patients who were diagnosed with HNSCC. In addition, HeLa and HEK cell lines were transfected with a Tbx3
BACKGROUND: Salvage surgery after concomitant chemoradiation therapy (CCRT) for patients with head and neck squamous cell carcinomas (HNSCC) is challenging because of its associated morbidity/mortality and the poor prognoses of these patients. METHODS: The outcome analysis of prospectively collected data from 93 patients with HNSCC with local and/or regional shows treatment failures but without distant metastasis after CCRT. RESULTS: Thirty-eight patients underwent salvage surgery, whereas 55 underwent palliative treatment, with 2-year overall survival rates of 43.4% and 0%, respectively. Initial stage IV tumors (p = .017) and concurrent local and regional failures (p = .003) were independent predictors for decreased survival after salvage surgery. Two-year overall survival rates for patients with 2, 1, or none of these predictive factors were 0%, 49%, and 83%, respectively (p = .0005). CONCLUSION: Salvage surgery after CCRT has acceptable outcomes. Initial stage IV tumors and concurre

The radical neck dissection specimens of 384 ethnically Chinese patients with different primary squamous carcinomas in the head and neck region were studied. Over 50 per cent of the specimens showed metastatic disease at one level in the neck. For oral cavity carcinoma, the levels of metastasis frequently involved were I, II and III while for carcinoma of the oropharynx, hypopharynx and larynx, the levels were II, III and IV. Extracapsular spread was present in 112/384 of patients (29 per cent) and this increased with advancing N-stages. Based on these findings, different selective neck dissections could be used for patients harbouring different primary head and neck carcinomas with limited neck disease ...
Head and neck squamous cell carcinoma (HNSCC) is comprised of metabolically linked distinct compartments. Cancer-associated fibroblasts (CAF) and nonproliferative carcinoma cells display a glycolytic metabolism, while proliferative carcinoma cells rely on mitochondrial oxidative metabolism fueled by the catabolites provided by the adjacent CAFs. Metabolic coupling between these reprogrammed compartments contributes to HNSCC aggressiveness. In this study, we examined the effects of cigarette smoke-exposed CAFs on metabolic coupling and tumor aggressiveness of HNSCC. Cigarette smoke (CS) extract was generated by dissolving cigarette smoke in growth media. Fibroblasts were cultured in CS or control media. HNSCC cells were cocultured in vitro and coinjected in vivo with CS or control fibroblasts. We found that CS induced oxidative stress, glycolytic flux and MCT4 expression, and senescence in fibroblasts. MCT4 upregulation was critical for fibroblast viability under CS conditions. The effects of CS ...
