NEDD 4 binding protein 2-like 1 promotes cancer cell invasion in oral squamous cell carcinoma - Semantic Scholar
Head and neck cancer, including oral squamous cell carcinoma, is the sixth most common cancer worldwide. Although cancer cell invasion and metastasis are crucial for tumor progression, detailed molecular mechanisms underlying the invasion and metastasis of oral squamous cell carcinoma are unclear. Comparison of transcriptional profiles using a cDNA microarray demonstrated that N4BP2L1, a novel oncogene expressed by neural precursor cells, is involved in oral squamous cell carcinoma. Expression of N4BP2L1 in oral squamous cell carcinoma is regulated by activation of miR-448 and is higher than in normal oral mucosa. Knockdown of N4BP2L1 and upregulation of miR-448 significantly reduced the invasive potential of oral squamous cell carcinoma cells. We studied N4BP2L1 expression in 187 cases of oral squamous cell carcinoma and found its overexpression to be significantly associated with nodal metastasis (P = 0.0155) and poor prognosis (P = 0.0136). Expression of miR-448 was found to be inversely associated

Grant Abstract: Chemoprevention of Lung Squamous Cell Carcinoma with Polphenon E
Abstract: ABSTRACT Although many mouse models of lung adenocarcinoma exist, there is no mouse lung squamous cell carcinoma model that has been validated for use in preclinical lung cancer chemoprevention studies. Since most clinical chemoprevention trials of lung cancer are performed in subjects with bronchial dysplasia, development of a lung squamous cell carcinoma mouse model becomes one of the highest priorities. We have shown that lung squamous cell carcinomas can be induced chemically in several strains of mice (Wang et al. 2004) and that green tea polyphenols exhibit a significant efficacy against the development of lung squamous cell carcinomas (preliminary data section). In this proposal, we will use a standardized green tea preparation called Polyphenon E (PE) and its major component, EGCG. The overall objective of this proposal is to determine the efficacy of green tea polyphenols in a mouse lung squamous cell carcinoma model and to determine the molecular mechanism that underlies the ...
Elevated activity of cyclin-dependent kinase 6 in human squamous cell carcinoma lines -- Timmermann et al. 8 (4): 361 -- Cell...
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 ...

Treatment of Squamous Cell Carcinoma, Squamous Cell Carcinoma Anus, Squamous Cell Carcinoma Definition, Causes, Risk Factors,...
Treatment of In November 2006, first lady Laura Bush had a small squamous cell carcinoma removed from her shin. Though hers was a high-profile case, it was by no means unique. An estimated 250,000 new cases of squamous cell carcinoma are diagnosed in the United States every year. And though squamous cell carcinoma was once found mainly in older adults, its occurring with increasing frequency in people younger than 40, Mrs. Bushs cancer was caught and treated early. In such cases, squamous cell carcinoma is highly curable and rarely causes further problems. But untreated squamous cell carcinoma can destroy healthy tissue around the tumor, spread to the lymph nodes or other organs, and occasionally prove fatal, Most squamous cell carcinomas result from prolonged exposure to ultraviolet radiation, either from sunlight or from tanning beds or lamps. Avoiding UV light as much as possible is the best protection. Sunscreen is an important part of a sun-safety program, but by itself doesnt completely prevent
Mutational Patterns in Metastatic Cutaneous Squamous Cell Carcinoma | Garvan Institute of Medical Research
Cutaneous squamous cell carcinoma from the head and neck typically metastasize to the lymph nodes of the neck and parotid glands. When a primary is not identified, they are difficult to distinguish from metastases of mucosal origin and primary salivary gland squamous cell carcinoma. UV radiation causes a mutation pattern that predominantly features cytosine to thymine transitions at dipyrimidine sites and has been associated with cutaneous squamous cell carcinoma. In this study, we used whole genome sequencing data from 15 cutaneous squamous cell carcinoma metastases and show that a UV mutation signature is pervasive across the cohort and distinct from mucosal squamous cell carcinoma. The mutational burden was exceptionally high and concentrated in some regions of the genome, especially insulator elements (mean 162 mutations/megabase). We therefore evaluated the likely impact of UV-induced mutations on the dipyrimidine-rich binding site of the main human insulator protein, CCCTC-binding factor, and the

Squamous cell carcinoma - Wikipedia
Squamous cell carcinomas, also known as epidermoid carcinoma are a number of different types of cancer that result from squamous cells. These cells form the surface of the skin lining of hollow organs in the body and line the respiratory and digestive tracts. Common types include: Squamous cell skin cancer: A type of skin cancer Squamous-cell carcinoma of the lung: A type of lung cancer Squamous cell thyroid carcinoma: A type of thyroid cancer Esophageal squamous cell carcinoma: A type of esophageal cancer Despite sharing the name squamous cell carcinoma, the SCCs of different body sites can show differences in their presented symptoms, natural history, prognosis, and response to treatment. Human papillomavirus infection (HPV) has been associated with SCC of the oropharynx, lung, fingers and anogenital region. Ninety percent of cases of head and neck cancer (cancer of the mouth, nasal cavity, nasopharynx, throat and associated structures) are due to squamous cell carcinoma. Primary squamous cell ...

The involvement of senescent cells in carcinogenesis has been highlighted in several cancer types and an interaction between cSCC cells and senescent cells is proposed, but still little explored. Tumor-associated effects are mostly attributed to the senescence-associated secretory phenotype (SASP). Here, we compared two in vitro models of senescence, namely replicative senescence and ...
Recurrent squamous cell carcinoma of the skin treated successfully wit | OTT
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

Purpose To discuss the expression of S100A4 and E-cad in oral squamous cell carcinoma (OSCC) and their significance.Methods Expression of S100A4 and E-cad was detected by using immunohistochemical SP method in oral squamous cell carcinoma.Correlation between the expression and clinicopathological features was analyzed.Results Expression of S100A4 had positive correlation with lymph node metastasis (P0.05), and no correlation with histological grade(P0.05). Expression of E-cad had positive correlation with histological grade and negative correlation with lymph node metastasis(P0.05). Inverse relationship between S100A4 and E-cad expression was observed in oral squamous cell carcinoma(P0.05).Conclusions E-cad plays an important role in differentiation of OSCC. E-cad and S100A4 is closely related to invasion and metastasis of OSCC. Expression of S100A4 and E-cadherin is significantly associated with tumor progression in oral squamous cell carcinoma,which are valuable markers in predicting biological

Background: Squamous cell carcinoma accounts for 1% of primary thyroid malignancies and is characterized by a rapidly unfavorable outcome. Case presentation: A 64-year-old woman presented with a painless mass in the left neck, coexisting with thyroid goiter. Total thyroidectomy with lymphadenectomy was performed and a primary thyroid squamous cell cancer was confirmed histologically after excluding any other possible primary malignancies. The tumors immunohistochemical profile was explored using a large panel of antibodies. The tumor featured a positive immunoreaction to cytokeratins 7-19 and to squamous cell carcinoma antigen. Low-molecular-weight cytokeratins 5- 6 and epithelial membrane antigen were also expressed. The neoplasms proliferative index (Mib1) was 60%. No immunostaining was detected for cytokeratins 10-20, thyroglobulin, TTF-1, CD5, galectin-3 or p53. Conclusions: This case of primary thyroid squamous cell carcinoma immunohistochemically profiled using a large panel of ...

Treatment of Squamous Cell Carcinoma
Squamous cell carcinoma is the second most common skin cancer and is increasing at an alarming rate, particularly in the elderly. Squamous cell carcinoma without question is related directly to sun exposure and also to age. The more sun and sunburns you have had and the longer you live the higher your risk of developing squamous cell carcinoma. They often come from precancerous lesions called actinic or solar keratoses which fair-haired, fair-eyed patients suffer from who have had sunburns as a child and have had chronic sun exposure. These red, raw, itchy, sometimes tender scaly spots on the scalp, face, ears, back of the hands and arms can convert to squamous cell carcinoma. Squamous cell carcinoma can also develop on its own and grow rapidly often fooling patients thinking they are bug bites, boils or infected hairs. These types of squamous cell carcinomas can be dangerous; they present as a nodule that hurts, grow rapidly and have between a 5%-25% risk of spreading or becoming metastatic ...

AIM: To investigate the putative role of human papillomavirus (HPV) infection in the carcinogenesis of esophageal squamous cell carcinoma in China.. METHODS: Twenty-three esophageal squamous cell carcinoma samples and the distal normal epithelium from Shanxi Province, and 25 more esophageal squamous cell carcinoma samples from Anyang city, two areas with a high incidence of esophageal cancer in China, were detected for the existence of HPV-16 DNA by PCR, mRNA in situ hybridization (ISH) and immunohistochemistry (IHC) targeting HPV-16 E6 gene.. RESULTS: There were approximately 64% (31/48) patients having HPV-16 DNA in tumor samples, among them nearly two-thirds (19/31) samples were detected with mRNA expression of HPV-16 E6. However, in the normal esophageal epithelium from cancer patients, the DNA and mRNA of HPV-16 were found with much less rate: 34.7% (8/23) and 26.1% (6/23) respectively. In addition, at protein level detected by IHC assay, 27.1% (13/48) tumor samples had virus oncoprotein E6 ...

Furthermore, amplification of the AIS locus was accompanied by RNA and protein overexpression of a variant p68(AIS) lacking the terminal transactivation domain. Protein overexpression in ...
Loss of Inositol Polyphosphate 5-Phosphatase Is an Early Event in Development of Cutaneous Squamous Cell Carcinoma
Abstract: Cutaneous squamous cell carcinoma (SCC) occurs commonly and can metastasize. Identification of specific molecular aberrations and mechanisms underlying the development and progression of cutaneous SCC may lead to better prognostic and therapeutic approaches and more effective chemoprevention strategies. To identify genetic changes associated with early stages of cutaneous SCC development, we analyzed a series of 40 archived skin tissues ranging from normal skin to invasive SCC. Using high-resolution array-based comparative genomic hybridization, we identified deletions of a region on chromosome 10q harboring the INPP5A gene in 24% of examined SCC tumors. Subsequent validation by immunohistochemistry on an independent sample set of 71 SCC tissues showed reduced INPP5A protein levels in 72% of primary SCC tumors. Decrease in INPP5A protein levels seems to be an early event in SCC development, as it also is observed in 9 of 26 (35%) examined actinic keratoses, the earliest stage in SCC ...
Eldorado: Estrogen receptor subtype agonist activation in human cutaneous squamous cell carcinoma cells modulates expression of...
Clinical studies indicate gender bias in cutaneous squamous cell carcinoma (cSCC) incidence with worse prognosis observed in males than in females, suggesting estrogen-mediated protection. In contrast, recent clinical population studies show risk of cSCC by use of oral contraceptives, thus raising controversy. However, animal studies indicate a protective role of estrogen and estrogen receptor (ER)s in cSCC. Currently we have a poor understanding of ERs that are expressed in human cSCC cells and their possible role in malignant transformation. The focus of current study was to determine ER subtype specific expression on cSCC A431 cells and investigate if ER agonist based activation modulates tumor markers CD55 and Cyclin D1 in the cells. ERα, ERβ and G protein-coupled receptor (GPR30) subtype expression at mRNA and protein level was determined in human cSCC A431 cells by reverse transcription-quantitative polym erase chain reaction (RT-qPCR) and Western blotting, respectively. The localization ...

Squamous cell carcinomas account for about 80% of cancers of the uterine cervix, and the majority of the remainder are adenocarcinomas. There is limited evidence on the extent to which these histological types share a common etiology. The International Collaboration of Epidemiological Studies of Cervical Cancer has brought together and combined individual data on 8,097 women with invasive squamous cell carcinoma, 1,374 women with invasive adenocarcinoma and 26,445 women without cervical cancer (controls) from 12 epidemiological studies. Compared to controls, the relative risk of each histological type of invasive cervical cancer was increased with increasing number of sexual partners, younger age at first intercourse, increasing parity, younger age at first full-term pregnancy and increasing duration of oral contraceptive use. Current smoking was associated with a significantly increased risk of squamous cell carcinoma (RR = 1.50, 95% CI: 1.35-1.66) but not of adenocarcinoma (RR = 0.86 (0.70-1.05)), and

We focused on the analysis of TP53 and PIK3CA gene variations in adenocarcinoma, squamous cell carcinoma as well as in intraepithelial neoplasia grade 3 of the cervix. DNA samples from 28 cervical adenocarcinoma, 55 squamous cell carcinoma and 31 intraepithelial neoplasia grade 3 (CIN3), previously characterized in terms of human papillomavirus (HPV) prevalence and genotype distribution, were analyzed for TP53 and PIK3CA mutations in the exons 4-9 and exon 9, respectively. Single nucleotide substitutions in TP53 and PIK3CA genes were detected in 36% and 11% of adenocarcinoma, in 16% and in 5% of squamous cell carcinoma, and in 13% and none of CIN 3, respectively. Nucleotide changes in TP53 were significantly more frequent in adenocarcinoma cases than in squamous cell carcinoma and CIN3 (P = 0.035) and were independent from HPV infection
Cureus | Cutaneous Metastasis From Tonsillar Squamous Cell Carcinoma: Report and Review of the Literature
Tonsillar squamous cell carcinoma, which represents 10% of head and neck malignancies, rarely manifests with cutaneous metastases; to date, only three prior patients with tonsillar squamous cell carcinoma have been reported to develop cutaneous metastases. We describe the clinical features of a 59-year-old man with squamous cell carcinoma of the tonsil who developed cutaneous metastases within his prior radiation port and review the literature of prior patients with cutaneous metastases from tonsillar squamous cell carcinoma. The PubMed database was searched for the following keywords: carcinoma, cutaneous, metastasis, squamous, and tonsil. The papers generated by the search and their references were reviewed. Cutaneous metastasis from tonsillar cancer is rare but should be considered in patients with a history of a squamous cell carcinoma of the tonsil; new skin lesions, both overlying the visceral malignancy and at more distant sites, should be biopsied since prognosis in these patients is poor.
Identification of genes associated with cisplatin resistance in human oral squamous cell carcinoma cell line | BMC Cancer |...
Cisplatin is widely used for chemotherapy of head and neck squamous cell carcinoma. However, details of the molecular mechanism responsible for cisplatin resistance are still unclear. The aim of this study was to identify the expression of genes related to cisplatin resistance in oral squamous cell carcinoma cells. A cisplatin-resistant cell line, Tca/cisplatin, was established from a cisplatin-sensitive cell line, Tca8113, which was derived from moderately-differentiated tongue squamous cell carcinoma. Global gene expression in this resistant cell line and its sensitive parent cell line was analyzed using Affymetrix HG-U95Av2 microarrays. Candidate genes involved in DNA repair, the MAP pathway and cell cycle regulation were chosen to validate the microarray analysis results. Cell cycle distribution and apoptosis following cisplatin exposure were also investigated. Cisplatin resistance in Tca/cisplatin cells was stable for two years in cisplatin-free culture medium. The IC50 for cisplatin in Tca

Thyroid gland involvement was found in 11% of the patients via direct spread in 92.3%. Single lobe involvement accounted for 61.5% of cases. There is a tendency for laryngeal squamous cell carcinoma to invade the thyroid lobe ipsilateral to ...
Klotho expression is correlated to molecules associated with epithelial‑mesenchymal transition in lung squamous cell carcinoma
Klotho is known as an anti‑aging gene. We previously reported that the expression of Klotho is a postoperative prognostic factor for patients with lung large cell neuroendocrine carcinoma and lung small cell carcinoma. Recently, Klotho was shown to suppress the epithelial‑mesenchymal transition (EMT). In the present study, we examined the association between the expression of Klotho and the regulation of EMT in lung squamous cell carcinoma. We immunohistochemically examined the expression of Klotho in patients with lung squamous cell carcinoma who had undergone surgical resection or photodynamic therapy. The immunohistochemical analysis showed that Klotho expression was observed not only in normal bronchial epithelial cells, but also in centrally located early lung cancers, which were all carcinomas in situ and were treated using PDT. However, in lung cancer patients with invasive and or advanced squamous cell carcinoma who had undergone a complete surgical resection, Klotho expression was ...
Aggressive radiotherapy dose de-escalation confers benefits in HPV-associated oropharyngeal squamous cell carcinoma - Oral...
Aggressively de-escalated adjuvant radiotherapy for patients with HPV-associated oropharynx squamous cell carcinoma produced local tumor control rates comparable to those of historical controls, according to results of a single-arm phase 2 study published in Journal of Clinical Oncology.. The de-escalated treatment also was associated with decreased toxicity and slight improvement in swallowing function.. HPV-associated oropharyngeal squamous cell carcinoma represents a demographically and biologically distinct disease compared with historical head and neck squamous cell carcinomas, Daniel J. Ma, MD, radiation oncologist at Mayo Clinic in Rochester, Minnesota, and colleagues wrote. Patients are more likely to be younger and nonsmokers and have fewer medical comorbidities. Furthermore, in vitro and in vivo experiments have demonstrated that these tumors are more sensitive to radiotherapy and chemotherapy compared with historical head and neck squamous cell carcinomas..

Basaloid squamous cell lung carcinoma - Wikipedia
Basaloid squamous cell carcinoma (Bas-SqCC) is an uncommon histological variant of lung cancer composed of cells exhibiting cytological and tissue architectural features of both squamous cell lung carcinoma and basal cell carcinoma. Lung cancer is a large and exceptionally heterogeneous family of malignancies. Over 50 different histological variants of lung cancer are explicitly recognized within the fourth (2004) revision of the World Health Organization Classification of Lung Tumours (WHO-2004). Many of these entities are quite rare, have only been recently described, and remain poorly understood. Basaloid forms of lung carcinoma were first described in the peer-reviewed medical literature by Dr. Elisabeth Brambilla and her colleagues in 1992. In the third revision of the World Health Organization lung tumor typing and classification scheme, published in 1999, basaloid variants of both squamous cell lung carcinoma (SqCC) and large cell lung carcinoma (LCLC) were recognized as distinct ...

CXCL12/CXCR4 promotes laryngeal and hypopharyngeal squamous cell carcinoma metastasis through MMP-13-dependent invasion via the...
Laryngeal and hypopharyngeal squamous cell carcinomas (LHSCCs) are common head and neck cancers with a high propensity for lymph node (LN) and lung metastasis. Here, we report that LHSCCs express high levels of functional CXCR4 receptors, native for chemokine stromal cell-derived factor-1 (SDF-1/CXCL12). Primary tumor immunohistochemistry from LHSCC patients has revealed significant expression of CXCR4 and CXCL12. Greater expression of CXCR4 but not that of CXCL12 is correlated with LN and distant metastasis. Reverse transcription-polymerase chain reaction and western blots have demonstrated that CXCR4 messenger RNA (mRNA) and protein were expressed in LHSCC cell lines as well, but failed to detect CXCL12 mRNA expression. CXCL12 treatment enhanced extracellular signal-regulated kinase (ERK) pathway activation and the motility/invasiveness of LHSCC cell lines, which were blocked by treatment with a CXCR4 antagonist (AMD3100) and a specific MEK inhibitor (U0126). Results show that the mRNA and ...

Our aim was to document the health-related quality of life (QoL) of patients with squamous cell carcinoma (SCC) of the oral cavity who were treated with chemoradiotherapy, and to compare it with that of patients treated with conventional surgery with or without adjuvant treatment. All patients who presented with SCC of the oral cavity treated with chemoradiotherapy alone at the Royal Brisbane & Womens Hospital between 2000 and 2011 and who were alive without disease were included. Health-related QoL was assessed by the University of Washington QoL questionnaire version 4, and the European Organisation for the Research and Treatment of Cancer (EORTC) QoL questionnaires C30 and HN35. The questionnaires were sent to all survivors. Those who responded to chemoradiotherapy were matched with patients who were treated by conventional surgery with or without adjuvant treatment by age, sex, subsite of tumour, and TNM stage. Sixteen patients completed the questionnaires (8 in each group). There was no ...
Prognostic role of HPV infection in esophageal squamous cell carcinoma | Infectious Agents and Cancer | Full Text
The aims of this study were to evaluate whether HPV infection has a prognostic role in patients with esophageal squamous cell carcinoma who underwent oncological treatment and also to compare the heat shock proteins (Hsp) 90, 27 and 16.2 and growth hormone-releasing hormone receptor (GHRH-R) expression patterns of the pre-treatment tumor biopsies with the HPV status and with the oncological response. Pre-treatment tumor biopsies of 74 patients with locally advanced esophageal squamous cell carcinoma were processed retrospectively. The presence of HPV was detected by chromogenic in situ hybridization. Hsp and GHRH-R expressions were determined using immunohistochemistry. Following neoadjuvant or definitive radiochemotherapy, the patients were restaged according to the Response Evaluation Criteria in Solid Tumors. The correlation between the HPV status, response to treatment and Hsp and GHRH-R expressions were evaluated. Fourteen (19%) patients were HPV-positive. These patients were more likely to respond

Repression of hTERT transcription by the introduction of chromosome 3 into human oral squamous cell carcinoma.
Telomerase is a ribonucleoprotein enzyme that maintains telomere length. Telomerase activity is primarily attributed to the expression of telomerase reverse transcriptase (TERT). It has been reported that introduction of an intact human chromosome 3 into the human oral squamous cell carcinoma cell line HSC3 suppresses the tumorigenicity of these cells. However, the mechanisms that regulate tumorigenicity have not been elucidated. To determine whether this reduction in tumorigenicity was...

Primary Pure Squamous Cell Carcinoma of Gallbladder Presenting as Acute Cholecystitis
Squamous cell carcinoma of the gallbladder is rare and constitutes only 0.5-3% of all malignancies of this organ. Most of the reported cases have had a component of adenocarcinoma. We report a 70-year-old man who presented with acute onset right upper quadrant pain. He operated on based on a presumptive diagnosis of acute cholecystitis according to clinical and ultrasonographic findings. Histopathological examination of the infiltrating mass of the gallbladder revealed well differentiated keratinized squamous cell carcinoma invading full wall thickness. Thorough evaluations revealed no other primary site for the tumor. Pure primary squamous cell carcinoma of the gallbladder is rarely reported. Clinicians and pathologists must be aware of its vague clinical presentations.
Detection of High-Risk Human Papillomavirus Genotypes 16 and 18 in Head and Neck Squamous Cell Carcinomas in Jordan
Background: Recently, associations of the human papillomavirus (HPV) with head and neck cancer have become well established. Of particular concern, the severity and pathological outcomes of squamous cell carcinomas are remarkably affected by the genotypes of HPV present in such lesions. This study was conducted to investigate the occurrence of HPV genotypes, particularly high risk 16 and 18, among oral and laryngeal squamous cell carcinomas in Jordan. Methods: During the period of May 2015 to March 2016, we evaluated a total of 108 paraffin-embedded tissue samples, histologically confirmed as SCC, of both oral and laryngeal tumors for the presence of HPV DNA. DNA was extracted using a Zymogen commercial kit. HPV genotypes were detected by nested PCR using consensus primers followed by primer-specific PCR for HPV-16 and HPV-18 genotypes. The genotypes were confirmed by DNA sequencing methods. Results: Sixteen samples were positive for HPV DNA (14.8%) with higher rates in oral tumors compared to their

Extranodal Extension as an Independent Prognostic factor in Laryngeal Squamous Cell Carcinoma Patients [Abstract]
The presence of Lymph node metastasis with extranodal extension (ENE) is considered to be an important adverse prognostic factor for survival in patients with head and neck cancer. The aim of this study was to determine the prognostic significance of ENE in patients with laryngeal squamous cell carcinoma (LSCC). Three hundred and fifty-five patients with LSCC who underwent surgical resection and neck dissection were included. The status of cervical lymph node was classified into three groups: pathological negative nodal (pN-), pathological positive nodal without ENE (ENE-), and pathological positive nodal with ENE (ENE+). A total of 85 of 355 (23.9%) LSCC were pathological nodal positive, and ENE was detected in 22/355 (6.2%) patients. ENE was associated with drinking (p=0.005), T stage (p=0.000), tumor location (p=0.000), and differentiation degree (p=0.000). The number of lymph node metastasis in ENE+ group was associated with almost twice compared to ENE- group (p=0.005). The 5-year overall ...

MicroRNA‑544 inhibits esophageal squamous cell carcinoma cell proliferation and enhances sensitivity to cisplatin by repressing...
Esophageal squamous cell carcinoma (ESCC) is one of the most common malignancies worldwide. MicroRNA (miRNA)‑544 is an important cancer‑associated RNA that is downregulated in multiple types of cancer. However, the role of miR‑544 in ESCC progression remains unknown. In the present study, miR‑544 expression level was determined via RT‑qPCR in 30 pairs of ESCC and adjacent normal tissues and in a panel of ESCC cell lines. Cell proliferation and cell apoptosis were assessed by MTT and flow cytometry assays. Luciferase reporter assay and western blot analysis were conducted to verify E2F transcription factor 5 (E2F5), an oncogene in ESCC, as a novel target gene of miR‑544. The results illustrated that miR‑544 is frequently downregulated in ESCC tissues and cell lines. Overexpression of miR‑544 in ESCC cells resulted in decreased cell proliferation and increased cell apoptosis. Thus, E2F5 was identified as a target of miR‑544, and its expression was negatively correlated with ...
Squamous Cell Lung Cancer [An Introduction]
Since this squamous cell lung cancer is being considered as destructive neoplasm in lungs, additional care is paid towards incorporating the effective supportive therapy in the regular anti cancerous therapy, involving multi drug combinations. The supportive therapy may include usage of suitable corticosteroid drugs like prednisolone in a routine form and it is noteworthy to mention that in some patients, a repository form of this corticosteroid may also be used to fulfill the need of constant delivery.. Surgery is also being considered as therapy in cases of squamous cell lung cancer. But, if the spread of this is over a wide area, it becomes impossible.. The squamous cell lung cancer in many patients tends to spread to other tissues including kidney or bone. Suppose, if it spreads to bones, most of the times, mandible or skull may get affected and in such cases increased density with occurrence of periosteal new bones may be noticed.. Squamous cell lung cancer at times need confirmation from ...
A long-surviving patient with advanced esophageal basaloid squamous cell carcinoma treated only with radiotherapy: case report...
Esophageal basaloid squamous cell carcinoma (EBSCC) is a rare malignant disease. Advanced EBSCC (AEBSCC) has a poorer prognosis than the more common esophageal squamous cell carcinoma, but no treatment policy has yet been established. This is the first reported case with AEBSCC treated only with radiotherapy. Thus, our long-surviving patient merits consideration. We therefore reviewed cases with the same stage of AEBSCC for further investigation. An 85-year-old man with a chief complaint of difficulty swallowing foods was diagnosed with AEBSCC, cT3N1M0, stage III, by thorough examination. The basaloid carcinoma extended from the upper thoracic esophagus to the middle thoracic esophagus based on imaging studies, endoscopy and biopsy. Morphologically, the tumor was an elevated ulcerative area. We conducted radiotherapy to relieve symptoms, as the patient and his family refused aggressive treatment. He has remained alive without recurrence for 2 years, to date, after completing radiotherapy. Basaloid

Prognostic significance and function of mammalian target of rapamycin in tongue squamous cell carcinoma. | Physicians Weekly...
Despite improvement in preoperative imaging, surgical technique, and adjuvant therapy, the prognosis of patients with tongue squamous cell carcinoma (SCC) is still unsatisfactory. The mammalian target of rapamycin (mTOR) play a key role in the regulation of tumor cell proliferation and survival. However, the significance of mTOR on the prognosis of tongue SCC remains largely undefined. In the present study, immunohistochemistry was performed to evaluate the expression of phosphorylated mTOR (p-mTOR) in 160 surgically resected tongue SCC, and correlated with survival. Univariate analysis revealed that p-mTOR overexpression (P = 0.006) was associated with inferior overall survival. In multivariate comparison, p-mTOR overexpression (P = 0.002, hazard ratio = 2.082) remained independently associated with worse overall survival. In vitro study, tongue cancer cells treated with everolimus, the specific mTOR inhibitor, or transfected with mTOR-mediated siRNAs dramatically attenuated the abilities of ...
