Mono Versus Polichemotherapy in Non Small Cell Lung Cancer (NSCLC) Elderly Patients - Full Text View - ClinicalTrials.govBetween 10% and 25% of newly diagnosed stage IIIB/stage IV patients currently receive single agent chemotherapy regimens. A significant proportion of these patients will be elderly (70 years of age) and many oncologists would consider intravenous vinorelbine or gemcitabine to be the standard of care in this patient population. It has been demonstrated that single agent vinorelbine offers therapeutic advantages to selected NSCLC patients over best supportive care alone.. Carboplatin plus Alimta have an acceptable toxicity profile and few clinical problems so it could be acceptable its use in elderly patients.. A randomised study is being performed therefore to assess whether progression free survival, the primary efficacy endpoint for this study, achieved with Carboplatin plus Alimta is superior than achieved with gemcitabine, one of the current standards of care in elderly patients with advanced NSCLC. ...

Plus itLung cancer is the most common cause of cancer mortality worldwide and continues to be a major health problem, exceeding the combined mortality rates of colorectal, breast and prostate cancers. It has proven difficult to control lung cancer with conventional therapeutic and surgical approaches, and generally the prognosis is poor with an overall five-year survival rate of 10-14% in the USA. A competent approach to reduce the mortality from lung cancer is the early detection of premalignant lesions as the survival of early stage lung cancer patients is much better as compared to patients with advanced cancers. The current mainstays of lung cancer therapy are surgical resection, radiation ablation and systemic chemotherapy with considerable toxicity. However, it appears unlikely that these therapies can cause striking improvements in near future. Thus, effective approaches to the prevention of lung cancer need ...

Survival after resection of synchronous bilateral lung cancerAbstract: Objective: Due to recent advances in imaging, the incidence of patients presenting with bilateral lung lesions is increasing. A single contralateral lung lesion can be an isolated metastasis or a synchronous second primary lung cancer. For the revision of the TNM in 2009, the International Association for the Study of Lung Cancer Staging Committee proposes that patients with contralateral lung nodules remain classified as M1 disease. In this retrospective study, the survival after resection of synchronous bilateral lung cancer is evaluated. Methods: From our database of bronchial carcinoma, all patients with bilateral synchronous lung lesions between 1990 and 2007 were retrieved. We analysed 57 patients in which, after functional assessment and thorough staging, the decision was taken to treat the disease with bilateral resection. All these files were retrospectively reviewed. ...
Progress in Respiratory Research Series. Volume 29. Updates in Advances in Lung Cancer. | ThoraxReasonably digestible reviews of recent clinical trials in the management of lung cancer are rare and, in general terms, this 11 chapter book is welcome. The emphasis here is on the use of chemotherapy and radiotherapy in the management of lung cancer, with eight of the 11 chapters considering these aspects, and the other three are concerned with chemoprevention, palliative medicine, and molecular biology.. Nine of the 11 authors are from the USA. The chapters take the form of a traditional review and are reasonably well set out with an average of about 50 references for each topic. The strengths of the book are the comprehensive assessment of novel drug therapies, with separate chapters for paclitaxel/carboplatin, gemcitabine, and docetaxel in non-small cell lung cancer, and a separate chapter on novel drugs for small cell lung cancer, including the topoisomerase-1 inhibitors, carboplatin, and the taxanes.. Sadly, the volume lacks an ...

Plus itBCAR4 was identified as tamoxifen resistance related gene in breast cancer due to its function to activate estrogen-independent cell growth. Instead of estrogen receptor, ERBB2 and ERBB3 genes were activated by BCAR4 in tamoxifen resistant cells. Recently, the function of BCAR4 as a long non-coding RNA (lncRNA) was reported to regulate a non-canonical Hedgehog/GLI2 pathway in breast cancer. However, the association of BCAR4 and lung cancer has not been identified. Here, we describe the oncogenic effect of BCAR4 in human lung cancer. Expression pattern of BCAR4 was examined in lung cancer cell lines, primary tumor tissues, and adjacent normal tissues. BCAR4 was highly expressed in 71% of lung cancer cell lines and especially in 43% of cancer tissues of lung adenocarcinoma patients who did not harbor the activational mutations of EGFR nor KRAS. Exogenous expression of BCAR4 protein promoted cell growth of non-tumorigenic ...
Plus itFUS1 is a novel tumor suppressor gene identified in the human chromosome 3p21.3 region. FUS1 gene was scarcely mutated both in lung cancer cell lines and primary lung cancers specimens, and the expression level mRNA similar to normal lung tissue. However, loss or reduction of FUS1 protein expression frequently occurs in lung cancer cell lines and primary lung cancers. It may due to haploinsufficiency and deficiency of posttranslational myristoylation which leads protein prone to rapid proteasome-dependent degradation or, alternatively, it may be resulted from translation repression by gene silencing of microRNA. FUS1 mRNA expression has been detected in numerous normal tissues such as heart, lung, skeletal muscle, kidney, brain, liver, pancreas and placenta. Herein, we examined the FUS1 mRNA expression by RT-PCR assay in 16 mesenchymal tumor cell lines and normal fibroblast cells, and in 110 malignant and 28 ...
UC Davis scientists identify new target for lung cancer treatmentA team of UC Davis investigators has discovered a protein on the surface of lung cancer cells that could prove to be an important new target for anti-cancer therapy. A series of experiments in mice with lung cancer showed that specific targeting of the protein with monoclonal antibodies reduced the size of tumors, lowered the occurrence of metastases and substantially lengthened survival time. The findings will be published in the November issue of Cancer Research.

Plus itIn this study, we report that in contrast to the malignant primary tumors, the spontaneous pulmonary metastases developed in PDX models can lose their metastatic potential and mesenchymal status and gain a more epithelial and differentiated status. This feature might be generalized to a group of patients with breast cancer with tumor metastases in the brain, liver, and lymph nodes (34). This phenomenon had initially been unexpected and was against the EMT dogma proposed in metastasis (42). However, more and more studies support that MET along with an epithelial state is required for colonization at the late stage of metastasis (43-45). Although there is still debate in the field, our studies indicate that metastasis is a complex procedure and the tumor cells that make it to the last step of colonization may not necessarily be very proliferative and mobile again. Similarly, an acquired luminal and nonmetastatic feature had been previously observed in certain breast cancer cell lines derived from ...
Plus itAlthough transforming growth factor ≤ (TGFβ) is anti-cancer identified, it was also known to promote tumor malignancy by enhancing the growth, epithelial to mesenchymal transition (EMT), tissue invasion and metastasis in a variety of cancer cells, including non-small cell lung cancers (NSCLCs). The aim of this study was to know the contribution of peroxisome proliferator-activated receptor ≤ (PPARδ) to TGFβ-promoted EMT and metastasis in NSCLCs. The degree of EMT, cell scattering, migration and invasion, and protein expression of PPARδ were first analyzed and compared between H460 and CH27 cells with or without TGFβ treatment (both are NSCLC cell lines). Chemical or shRNA blocking assay was also utilized to further confirm the importance of PPARδ in promoting TGFβ-induced tumor metastasis. Finally, signaling pathway(s) responsible for TGFβ/PPARδ-mediated metastasis was evaluated. The results demonstrated that TGFβ can effectively triggered the EMT, cell scattering, migration and ...

Plus itPurpose: Here, we sought to identify critical genes, whose depletion and inhibition caused differential cytotoxicity in SMARCA4-mutant non-small cell lung cancers (NSCLCs).. Background: The SWI/SNF complex is a master regulator of gene expression, affecting at least 10% of the transcriptome. Because of its crucial role in controlling cell cycle, development and differentiation, the SWI/SNF complex components function as tumor suppressor genes. Therefore, not surprisingly, the ATPases SMARCA2 and SMARCA4 are frequently down-regulated in cancers and mutations of SMARCA4 are frequently present in many cancer types including lung cancers. However, currently, no single therapeutic agent has been identified as synthetically lethal with SMARCA4 loss.. To identify SMARCA4-inactivating mutation related targetable gene products, we developed and applied a high throughput cell-based one-well/one-gene screening platform with a genome-wide synthetic library of chemically synthesized ...
Plus itNovel cancer therapeutics target proteins with key functions in cell survival and migration, protein turnover, mitosis regulation, or angiogenesis. These targets include receptor tyrosine (Y) kinases (e.g. BCR/ABL, EGF-R, FLT-3, Her-2, PDGF-R, KDR, c-KIT, Src, VEGF-R), serine-threonine (S/T) specific kinases (e.g. Aurora A/B (ARK), B-raf), and the chaperone Hsp90. At Oncotest, a unique profiling screen for anticancer agents is routinely done, using a clonogenic assay in a panel of 48 proprietary solid tumor xenografts. The xenograft models were in general established directly from patient tumors, representing all major tumor histotypes (non-small cell lung cancer/NSCLC, pancreatic, prostate, colon, gastric, breast, ovarian and renal cancer, melanoma and sarcoma) as well as niche tumors (pleuramesothelioma, bladder and head and neck cancer). After an initial profiling screen in the 48 tumor panel, follow-up testing in defined tumor histotypes are of high value for hypothesis generation and ...

(1/26018) Human papillomavirus DNA in adenosquamous carcinoma of the lung.
AIM: To investigate the presence of human papillomavirus (HPV) DNA in adenosquamous carcinoma of the lung--which is relatively common in Okinawa but not in mainland Japan--and examine its histological features. METHODS: Of 207 cases where primary lung cancers were surgically removed between January 1995 and June 1997 in Okinawa, 23 were adenosquamous carcinoma. HPV was detected by non-isotopic in situ hybridisation (NISH) and polymerase chain reaction (PCR) amplification with primers specific for E6 and E7 regions of the HPV genome. PCR products were analysed by Southern blotting. Immunohistochemical determination of high molecular weight cytokeratin (HMC) and involucrin was also carried out. RESULTS: 18 cases were positive for HPV DNA by PCR and NISH. HPV types 6, 11, 16, and 18 were found. Seven cases were dual positive for different types of HPV. Using NISH, HPV was also found in the squamous cell components and in neighbouring enlarged adenocarcinoma cells. The HMC and involucrin were demonstrated immunohistochemically in the same areas. CONCLUSIONS: HPV DNA was found in a high proportion (78.3%) of adenosquamous carcinomas in Okinawa, a region where HPV has previously been shown to be prevalent in squamous cell carcinoma of the lung. The adenocarcinoma cells adjacent to the squamous cell carcinoma component were enlarged and positive for HPV, HMC, and involucrin. This is thought to indicate the transition from adenocarcinoma to squamous cell carcinoma. (+info)
(2/26018) Correlation between the status of the p53 gene and survival in patients with stage I non-small cell lung carcinoma.
The association of p53 abnormalities with the prognosis of patients with non-small cell lung carcinoma (NSCLC) has been extensively investigated to date, however, this association is still controversial. Therefore, we investigated the prognostic significance of p53 mutations through exons 2 to 11 and p53 protein expression in 103 cases of stage I NSCLC. p53 mutations were detected in 49 of 103 (48%) tumors. Two separate mutations were detected in four tumors giving a total of 53 unique mutations in 49 tumors. Ten (19%) of mutations occurred outside exons 5-8. Positive immunohistochemical staining of p53 protein was detected in 41 of 103 (40%) tumors. The concordance rate between mutations and protein overexpression was only 69%. p53 mutations, but not expression, were significantly associated with a shortened survival of patients (P<0.001). Furthermore, we investigated the correlation between the types of p53 mutations and prognosis. p53 missense mutations rather than null mutations were associated with poor prognosis (P < 0.001 in missense mutations and P=0.243 in null mutations). These results indicated that p53 mutations, in particular missense mutations, rather than p53 expression could be a useful molecular marker for the prognosis of patients with surgically resected stage I NSCLC.

(3/26018) Comparative efficacy of positron emission tomography with FDG and computed tomographic scanning in preoperative staging of non-small cell lung cancer.
OBJECTIVE: To determine the sensitivity, specificity, and accuracy of positron emission tomography with 2-fluorine-18-fluorodeoxyglucose (PET-FDG) in the preoperative staging (N and M staging) of patients with lung cancer. The authors wanted to compare the efficacy of PET scanning with currently used computed tomography (CT) scanning. MATERIALS AND METHODS: Results of whole-body PET-FDG imaging and CT scans were compared with histologic findings for the presence or absence of lymph node disease or metastatic sites. Sampling of mediastinal lymph nodes was performed using mediastinoscopy or thoracotomy. RESULTS: PET-FDG imaging was significantly more sensitive, specific, and accurate for detecting N disease than CT. PET changed N staging in 35% and M staging in 11% of patients. CT scans helped in accurate anatomic localization of 6/57 PET lymph node abnormalities. CONCLUSION: PET-FDG is a reliable method for preoperative staging of patients with lung cancer and would help to optimize management of these patients. Accurate lymph node staging of lung cancer may be ideally performed by simultaneous review of PET and CT scans. (+info)
(4/26018) Overexpression of the multidrug resistance-associated protein (MRP1) in human heavy metal-selected tumor cells.
Cellular and molecular mechanisms involved in the resistance to cytotoxic heavy metals remain largely to be characterized in mammalian cells. To this end, we have analyzed a metal-resistant variant of the human lung cancer GLC4 cell line that we have selected by a step-wise procedure in potassium antimony tartrate. Antimony-selected cells, termed GLC4/Sb30 cells, poorly accumulated antimony through an enhanced cellular efflux of metal, thus suggesting up-regulation of a membrane export system in these cells. Indeed, GLC4/Sb30 cells were found to display a functional overexpression of the multidrug resistance-associated protein MRP1, a drug export pump, as demonstrated by Western blotting, reverse transcriptase-polymerase chain reaction and calcein accumulation assays. Moreover, MK571, a potent inhibitor of MRP1 activity, was found to markedly down-modulate resistance of GLC4/Sb30 cells to antimony and to decrease cellular export of the metal. Taken together, our data support the conclusion that overexpression of functional MRP1 likely represents one major mechanism by which human cells can escape the cytotoxic effects of heavy metals.

(5/26018) Expression of tissue factor in non-small-cell lung cancers and its relationship to metastasis.
Tissue factor (TF) is an initiator of the extrinsic cascade of blood coagulation. Although recent studies have revealed a relationship between metastatic properties and TF expression in some neoplastic cells, the significance of TF in lung cancer, especially in non-small-cell lung cancer (NSCLC), is still unclear. In this study, TF was detected in NSCLC cell lines by functional study, Western blot analysis and immunocytochemical staining. TF levels in eight NSCLC cell lines were also quantitated by enzyme-linked immunosorbent assay (ELISA), and TF expression was evaluated in 55 specimens of surgically resected NSCLCs. NSCLC cell lines derived from metastatic lesions produced high levels of TF (48.3+/-23.5 ng 10(-6) cells, mean +/- s.e.m.), whereas those derived from primary lesions produced low levels of TF (0.2+/-0.1 ng 10(-6) cells). Immunohistochemical studies disclosed significantly stronger staining for TF in cells from NSCLC patients with metastasis than in those without metastasis. Among the 28 patients with metastasis, ten were strongly positive, 16 were moderately positive and two were negative for TF. In contrast, among the 27 patients without metastasis, only two were strongly positive, 18 were moderately positive and seven were negative for TF. Therefore, malignant cells from patients with lung cancer produce various levels of TF, and TF may play an important role in the metastatic process. (+info)
(6/26018) Early death during chemotherapy in patients with small-cell lung cancer: derivation of a prognostic index for toxic death and progression.
Based on an increased frequency of early death (death within the first treatment cycle) in our two latest randomized trials of combination chemotherapy in small-cell lung cancer (SCLC), we wanted to identify patients at risk of early non-toxic death (ENTD) and early toxic death (ETD). Data were stored in a database and logistic regression analyses were performed to identify predictive factors for early death. During the first cycle, 118 out of 937 patients (12.6%) died. In 38 patients (4%), the cause of death was sepsis. Significant risk factors were age, performance status (PS), lactate dehydrogenase (LDH) and treatment with epipodophyllotoxins and platinum in the first cycle (EP). Risk factors for ENTD were age, PS and LDH. Extensive stage had a hazard ratio of 1.9 (P = 0.07). Risk factors for ETD were EP, PS and LDH, whereas age and stage were not. For EP, the hazard ratio was as high as 6.7 (P = 0.0001). We introduced a simple prognostic algorithm including performance status, LDH and age. Using a prognostic algorithm to exclude poor-risk patients from trials, we could minimize early death, improve long-term survival and increase the survival differences between different regimens. We suggest that other groups evaluate our algorithm and exclude poor prognosis patients from trials of dose intensification. (+info)
(7/26018) Defining and analysing symptom palliation in cancer clinical trials: a deceptively difficult exercise.
The assessment of symptom palliation is an essential component of many treatment comparisons in clinical trials, yet an extensive literature search revealed no consensus as to its precise definition, which could embrace relief of symptoms, time to their onset, duration, degree, as well as symptom control and prevention. In an attempt to assess the importance of these aspects and to compare different methods of analysis, we used one symptom (cough) from a patient self-assessment questionnaire (the Rotterdam Symptom Checklist) in a large (>300 patient) multicentre randomized clinical trial (conducted by the Medical Research Council Lung Cancer Working Party) of palliative chemotherapy in small-cell lung cancer. The regimens compared were a two-drug regimen (2D) and a four-drug regimen (4D). No differences were seen between the regimens in time of onset of palliation or its duration. The degree of palliation was strongly related to the initial severity: 90% of the patients with moderate or severe cough at baseline reported improvement, compared with only 53% of those with mild cough. Analyses using different landmark time points gave conflicting results: the 4D regimen was superior at 1 month and at 3 months, whereas at 2 months the 2D regimen appeared superior. When improvement at any time up to 3 months was considered, the 4D regimen showed a significant benefit (4D 79%, 2D 60%, P = 0.02). These findings emphasize the need for caution in interpreting results, and the importance of working towards a standard definition of symptom palliation. The current lack of specified criteria makes analysis and interpretation of trial results difficult, and comparison across trials impossible. A standard definition of palliation for use in the analysis of clinical trials data is proposed, which takes into account aspects of onset, duration and degree of palliation, and symptom improvement, control and prevention.

(8/26018) Expression and tissue localization of membrane-type 1, 2, and 3 matrix metalloproteinases in human astrocytic tumors.
Three different membrane-type matrix metalloproteinases (MT1-, MT2-, and MT3-MMPs) are known to activate in vitro the zymogen of MMP-2 (pro-MMP-2, progelatinase A), which is one of the key MMPs in invasion and metastasis of various cancers. In the present study, we have examined production and activation of pro-MMP-2, expression of MT1-, MT2-, and MT3-MMPs and their correlation with pro-MMP-2 activation, and localization of MMP-2, MT1-MMP, and MT2-MMP in human astrocytic tumors. The sandwich enzyme immunoassay demonstrates that the production levels of pro-MMP-2 in the anaplastic astrocytomas and glioblastomas are significantly higher than that in the low-grade astrocytomas (P<0.05 and P<0.01, respectively), metastatic brain tumors (P<0.05), or normal brains (P<0.01). Gelatin zymography indicates that the pro-MMP-2 activation ratio is significantly higher in the glioblastomas than in other astrocytic tumors (P<0.01), metastatic brain tumors (P<0.01), and normal brains (P<0.01). The quantitative reverse transcription polymerase chain reaction analyses demonstrate that MT1-MMP and MT2-MMP are expressed predominantly in glioblastoma tissues (17/17 and 12/17 cases, respectively), and their expression levels increase significantly as tumor grade increases. MT3-MMP is detectable in both astrocytic tumor and normal brain tissues, but the mean expression level is approximately 50-fold lower compared with that of MT1-MMP and MT2-MMP in the glioblastomas. The activation ratio of pro-MMP-2 correlates directly with the expression levels of MT1-MMP and MT2-MMP but not MT3-MMP. In situ hybridization indicates that neoplastic astrocytes express MT1-MMP and MT2-MMP in the glioblastoma tissues (5/5 cases and 5/5 cases, respectively). Immunohistochemically, MT1-MMP and MT2-MMP are localized to the neoplastic astrocytes in glioblastoma samples (17/17 cases and 12/17 cases, respectively), which are also positive for MMP-2. In situ zymography shows gelatinolytic activity in the glioblastoma tissues but not in the normal brain tissues. These results suggest that both MT1-MMP and MT2-MMP play a key role in the activation of pro-MMP-2 in the human malignant astrocytic tumors and that the gelatinolytic activity is involved in the astrocytic tumor invasion.

- Dose-response associations of silica with nonmalignant respiratory disease and lung cancer mortality in the diatomaceous earth industry. (cdc.gov)
- A study of mortality of workers in the diatomaceous-earth (DE) industry was conducted to examine possible associations between crystalline silica (14808607) exposure and lung cancer and nonmalignant respiratory disease (NMRD) risk among DE industry workers. (cdc.gov)
- Associations between NMRD and lung cancer mortality and cumulative silica dust exposures estimated from industrial hygiene monitoring data and detailed job histories of the decedents were examined. (cdc.gov)
- Mortality from lung cancer and NMRD was significantly increased, SMRs 1.29 and 2.01, respectively. (cdc.gov)
- The same comparison showed a significant, but weaker trend for lung cancer, RR 2.15. (cdc.gov)
- Adjusting for smoking reduced the maximum RRs for NMRD and lung cancer to 4.15 and 1.67, respectively. (cdc.gov)
- A weaker dose response trend for lung cancer has been detected. (cdc.gov)
- These associations are unlikely to reflect the effects of asbestos exposure or smoking and add further support to the view that silica dust is involved in the etiology of lung cancer. (cdc.gov)
