    In most patients, lung cancer presents as advanced disease with metastases to lymph nodes and/or distant organs, and survival is poor. Lung cancer is also a highly immune-suppressing malignancy with numerous methods to evade antitumor immune responses, including deficiencies in antigen processing and presentation, release of immunomodulatory cytokines, and inhibition of T-cell activation. Advances in understanding the complex interactions of the immune system and cancer have led to novel therapies that promote T-cell activation at the tumor site, resulting in prolonged clinical benefit. Immune checkpoint inhibitors, specifically programmed death receptor 1 pathway antibodies, have demonstrated impressively durable responses and improved survival in patients with non-small cell lung cancer. This article will review the recent progress made in immunotherapy for lung cancer with data from trials evaluating programmed death receptor 1 and cytotoxic T-lymphocyte-associated protein 4 monoclonal antibodies in addition to cancer vaccines. The review will focus on studies that have been published and the latest randomized trials exploring immune therapy in lung cancer. These results form the framework for a new direction in the treatment of lung cancer toward immunotherapy. PMID:27058851

    Maintenance therapy is a new treatment strategy for advanced non-small-cell lung cancer(NSCLC), and it consists of switch maintenance and continuation maintenance.Switch maintenance is the introduction of a different drug, not included as part of the induction therapy, immediately after completion of 4 cycles of first-line platinum-based chemotherapy.Continuation maintenance is a continuation of at least one of the drugs used in the induction therapy in the absence of disease progression.Several phase III trials have reported survival benefits with continuation maintenance of pemetrexed and switch maintenance of pemetrexed or erlotinib.Therefore, maintenance therapy has become a part of the standard first-line treatment for advanced NSCLC.However, further research is needed to elucidate the selection criteria of patients who may benefit the most from maintenance therapy.

    Full Text Available Non-small cell lung cancer is the most common pathological type of lung cancer. Along with the rising incidence in recent years, lung cancer has been the leading cause of death due to malignancies both in our country and worldwide. Due to simplistic therapeutic approach for lung cancer decades ago, those patients suffering from advanced lung cancer had short lifetime, and it was difficult to ensure their life quality. In recent years, many molecular targeted drugs, such as Gefitinib, Erlotinib and Crizotinib etc., have been successively applied in clinical use, and they bring about a substantial prolongation of survival life and improvement in life quality of those patients with advanced lung cancer. In 2014, there was a number of important reports concerning the diagnosis and treatment of non-small cell lung cancer in the annual meetings of either American Society of Clinical Oncology or European Society for Medical Oncology. On the basis of the relevant reports delivered in the conferences, it is our attempt to summarize the recent advances in regard to chemotherapy, molecular targeted therapy, measures to treat TKI therapy resistant cases, and immune therapy, followed by a comment regarding recent advances in the treatment of non-small cell lung cancer in 2014.

    Full Text Available Data supporting use of concurrent chemoradiation in locally advanced lung cancers comes from clinical trials from developed countries. Applicability and outcomes of such schedules in developing countries is not widely reported. There are various challenges in delivering chemoradiation in locally advanced non small cell lung cancer in developing countries which is highlighted by an audit of patients treated with chemoradiation in our center. This article deals with the challenges in the context of a developing country. We conclude that sequential chemoradiotherapy is better tolerated than concurrent chemoradiation in Indian patients with locally advanced non-small cell lung cancers. Patients with stage IIIa, normal weight or overweight, and adequate baseline pulmonary function should be offered concurrent chemoradiation.

    Non-small cell lung carcinoma is a leading cause of cancer death worldwide. Understanding the molecular biology of survival and proliferation of cancer cells led to a new molecular classification of lung cancer and the development of targeted therapies with promising results. With the advances of image-guided biopsy techniques, tumor samples are becoming smaller, and the molecular testing techniques have to overcome the challenge of integrating the characterization of a panel of abnormalities including gene mutations, copy-number changes, and fusions in a reduced number of assays using only a small amount of genetic material. This article reviews the current knowledge about the most frequent actionable molecular abnormalities in non-small cell lung carcinoma, the new approaches of molecular analysis, and the implications of these findings in the context of clinical practice.

    Full Text Available Background: For inoperable non-small cell lung cancer combined chemotherapy and radiotherapy plays an important role as a therapeutic modality. The aim of the present study was to analyze neoadjuvant chemotherapy related acute toxicity in locally advanced lung cancer (stage IIIA and IIIB in Indian patients using Cisplatin and Etoposide combination chemotherapy. Material and methods: Forty patients of locally advanced Non small cell lung cancer received three cycles neoadjuvant chemotherapy using Injection Cisplatin and Etoposide. The patients were taken for Radical radiotherapy to a dose of 60 Gray over 30 fractions in conventional fractionation after completing chemotherapy. Chemotherapy associated toxicity was assessed using common toxicity criteria (CTC v2.0 Results: Forty patients were available for final evaluation. Median age of presentation of patients was fifty-six years. Thirteen patients had Non small cell lung cancer stage IIIA while twenty-seven patients had Stage IIIB disease. Anemia was the most common hematological toxicity observed (seen in 81% of patients. Nausea and vomiting were the most common non -hematological toxicity seen. Sensory neuropathy was seen in 38%of patients. 88% patients developed alopecia. Seven patients developed febrile neutropenias. Conclusion: Neo-adjuvant chemotherapy using Cisplatin and Etoposide continues to be a basic regimen in the Indian set up despite availability of higher molecules, since it is cost effective, well tolerated and therapeutically effective. Blood transfusions, growth factors and supportive care can be used effectively to over come toxicity associated with this regimen.

    Lung cancer has a poor prognosis; over half of people diagnosed with lung cancer die within one year of diagnosis and the 5-year survival is less than 18%. Non-small cell lung cancer (NSCLC) accounts for the majority of all lung cancer cases. Risk factors for developing NSCLC have been identified, with cigarette smoking being a major factor along with other environmental and genetic risk factors. Depending on the staging of lung cancer, patients are eligible for certain treatments ranging from surgery to radiation to chemotherapy as well as targeted therapy. With the advancement of genetics and biomarkers testing, specific mutations have been identified to better target treatment for individual patients. This review discusses current treatments including surgery, chemotherapy, radiotherapy, and immunotherapy as well as how biomarker testing has helped improve survival in patients with NSCLC.

    The intensity of complains, short survival and great number of patients makes many oncologists to apply chemotherapy in advanced non-small cell lung cancer/NSCLC/. The achieved median duration of life after chemotherapy was 6 to 12 month. From the other hand non small cell lung cancer chemotherapy is a big burden even to healthy persons. It can worsen the quality of life. That was the reason we evaluated the quality of life after chemotherapy in advanced non small cell lung cancer patients. Taking into account, that the evaluation of quality of life, used in most diseases is useless in advanced NSCLC patients, for appreciation the quality of life in these cases the lung cancer symptoms scale/LCSS/was adopted. In 110 non small cell lung cancer patients in stage IIIB and IV, who received combined chemotherapy by Le Chevalier/Vindesine, Cisplatin, Cyclophosphamide, Lomustin/or by Rosell/Mitomycin, Cyclophosphamide, Cisplatin/the quality of life was evaluated. In 20-persons control group all patients received the symptomatic treatment. In observed group of 110 patients, tumor regressions after 4 courses of chemotherapy allowed to resect cancer in 14 cases, to apply radiotherapy in 42 and to continue chemiotherapy in 23 persons. In every person from above mentioned group the quality of life was evaluated on the basis of intensity of cancer symptoms, accordingly to LCSS. The intensity of cancer symptoms was compared before and after treatment. There were compared; the innensity of complains, weakness, appetite, malnutrition, and hematological, neurological, performans state as well as respiratory sufficiency, infections, cardiac disorders and pain. Apart it, the side effects of applied therapy were assessed in 5 degree scale. The level of hemoglobin, the number of leucocytes, thrombocytes, bilirubine and transaminases in peripheral blood, hematurie, proteinurie, bleedings, appetite, nausea, vomitings, diarrhea, mucosal lesions, infections, skin lesions, cardiac lesions

    Because of increasing life expectancy and of higher risk of cancer with ageing, lung cancer in elderly is a frequent disease. For a long time nihilism influenced treatment decisions in elderly patients with advanced non-small cell lung cancer. Since the beginning of the last decade single agent chemotherapy has been accepted as standard of care, vinorelbine and gemcitabine being the most frequently used drugs in Europe and US, docetaxel in Japan. Platinum-based doublets have been shown to be superior to monotherapy in young and fit patients with advanced non-small cell lung cancer. Although there were some indications from subgroup analyses of clinical trials not specifically dedicated to elderly patients that a platinum-based doublet might also benefit to older patients, there was no definitive proof of concept until ASCO meeting 2010. At this meeting results of a phase 3 trial showed that PS 0-2 patients, aged 70-89 years drove a significant benefit from a treatment with carboplatin associated to weekly paclitaxel compared to a monotherapy. Thus, the paradigm of treatment in elderly patients should perhaps be modified from a single agent to doublet chemotherapy. Whether other platinum-based doublets would provide the same benefit as the specific one studied remains to be evaluated. PMID:21893363

    Full Text Available BACKGROUND: Circulating endothelial cells and microparticles have prognostic value in cancer, and might be predictors of response to chemotherapy and antiangiogenic treatments. We have investigated the prognostic value of circulating endothelial cells and microparticles in patients treated for advanced non-small cell lung cancer. METHODOLOGY/PRINCIPAL FINDINGS: Peripheral blood samples were obtained from 60 patients before first line, platinum-based chemotherapy +/- bevacizumab, and after the third cycle of treatment. Blood samples from 60 healthy volunteers were also obtained as controls. Circulating endothelial cells were measured by an immunomagnetic technique and immunofluorescence microscopy. Phosphatidylserine-positive microparticles were evaluated by flow cytometry. Microparticle-mediated procoagulant activity was measured by the endogen thrombin generation assay. RESULTS: pre- and posttreatment levels of markers were higher in patients than in controls (p<0.0001. Elevated levels of microparticles were associated with longer survival. Elevated pretreatment levels of circulating endothelial cells were associated with shorter survival. CONCLUSIONS/SIGNIFICANCE: Circulating levels of microparticles and circulating endothelial cells correlate with prognosis, and could be useful as prognostic markers in patients with advanced non-small cell lung cancer.

    Full Text Available At present, in the treatment of non-small cell lung cancer (NSCLC, targeted therapy has an important status. After epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKIs, crizotinib targeted at EML4-ALK fusion gene becomes a significant drug of molecular targeted therapy in NSCLC. Phase I and II clinical trials prove that crizotinib is effective for treatment of activating EML4-ALK mutation in advanced NSCLC patients, little side-effect, and well tolerated. Recently, crizotinib can inhibit ROS1 receptor tyrosine kinase and show extraordinary significant antitumor activity in ROS1-rearranged NSCLC. Drug resistance also exists in crizotinib. The mechanism of drug resistance needs further research. In this study, a review is performed in the mechanism and pharmacokinetics of crizotinib, and the clinical progress of treatment in advanced NSCLC.

    Aspergillus spp. is a pathogenic fungus in patients with malignancy, immunosuppression or respiratory diseases, and invasive pulmonary aspergillosis (IPA) caused by its infection is an aggressive and often lethal disorder. We report a case of non-small-cell lung cancer (NSCLC) where pneumonectomy concomitantly enabled radical cure of the underlying disease and IPA against which different antifungal drugs had been ineffective. In a patient with locally advanced NSCLC that progressed despite chemoradiation, radiation pneumonitis and subsequently cavitary disease developed following the administration of corticosteroids. Based upon the isolation of Aspergillus spp. from sputum, a diagnosis of IPA was made and since the latter was refractory to multiple antifungal drugs, pneumonectomy was undertaken which resulted in successful treatment of both NSCLC and IPA. Surgical intervention should be considered as a therapeutic option for IPA complicating NSCLC that is refractory to medical management. PMID:23505081

    International Nuclear Information System (INIS)

    Nine patients with non-small cell lung carcinoma (4 squamous, 4 adenocarcinoma, 1 large cell) were treated with a combination of radiation therapy and cyclic chemotherapy with 5-fluorouracil, methotrexate and platinum. Four previously untreated patients had stage III, 2 having distant metastases, 5 previously treated patients were restaged as stage III with distant metastasis in one. Moderate hematologic toxicity was noted. Objective responses occurred in 67 per cent, regardless of previous treatment or performance status. Responders survived for a median of 11 months with one complete response patient surviving at 14 months while 5 partial response patients survived for a median of 10 months. This regimen is feasible and its utility as the initial treatment of locally advanced disease should be further investigated. (Auth.)

    Lung cancer is the leading cause of death cancer related worldwide. The standard therapies have unmet medical needs both due to the limited activity and relevant toxicity of platinum-based chemotherapy and to the low frequency of specific alterations required to use targeted therapies. Immune checkpoint inhibition due to restoring the immune system's capacity to eradicate tumors is undergoing in extensive investigation in non-small cell lung cancer (NSCLC) as a new treatment approach. Programmed cell death protein-1 (PD-1) and its ligand, programmed cell death-ligand 1 (PD-L1) have recently led to significantly and durable improvements in the clinical outcome of several kind of tumors including lung cancer. Pembrolizumab, approved by the U.S. FDA for the treatment of advanced NSCLC progressed after other therapies and with expression of PD-L1, has demonstrated durable response and prolonged overall survival (OS) especially in patients with high PD-L1 expression. Further investigation are needed to improve treatment outcomes through combination of immunotherapy or combined with other targeted therapies.

    Combination chemotherapy has been shown to improve overall survival compared with best supportive care in patients with advanced non-small cell lung cancer (NSCLC). The survival advantage is modest and was initially demonstrated with cisplatin-containing regimens in a large meta-analysis of randomized trials reported in 1995. Newer chemotherapy combinations have been shown to be better tolerated than older cisplatin-based combinations, and some trials have also shown greater efficacy and survival benefits with these newer combinations. Combination chemotherapy is, therefore, the currently accepted standard of care for patients with good performance statuses aged less than 70 years with advanced NSCLC. However, there are limited data from clinical trials to support the use of combination chemotherapy in elderly patients over 70 years of age with advanced NSCLC. Subgroup analyses of large randomized phase III trials suggest that elderly patients with good performance statuses do as well as younger patients treated with combination chemotherapy. There are few randomized trials reported that evaluate chemotherapy in patients aged greater than 70 years only. Based on data from trials performed by an Italian group, single-agent vinorelbine has been shown to have significant activity in elderly patients with advanced NSCLC and to be well tolerated by those patients with Eastern Cooperative Oncology Group performance statuses of two or less, with associated improvements in measures of global health.

Methods: The clinical data of 260 patients with advanced NSCLC treated with icotinib hydrochloride in Jiangsu Cancer Hospital was retrospectively analyzed. Results:Four weeks after initial administration, 256 patients were evaluable for efifcacy except 4 who withdrew the drug due to intolerable adverse responses. Among the 256 patients, there were 0 complete response (CR), 96 partial response (PR, 37.5%), 97 stable disease (SD, 37.9%) and 63 progression disease (PD, 24.6%), with the objective remission rate (ORR) and disease control rate (DCR) being 37.6%and 75.4%respectively. However, in all patients, the median progression-free survival (PFS) was 7 (0.4~16.3) months, and were 11 (1~16.3), 6 (0.4~11.3) and 5 (1~13.5) months in those treated with ifrst-line, second-line, and≥third-line treatments, respectively. Conclusion: Icotinib hydrochloride has significant efficiency and better safety for treating advanced NSCLC.

    This study was to evaluate effect of 125I brachytherapy combined with chemotherapy on advanced non-small cell lung cancer (NSCLC). Patients with NSCLC in stages III to IV were divided into two groups: Group A (n = 27) received 125I brachytherapy combined with gemcitabine and cisplatin (GP) chemotherapy, and Group B (n = 27) received GP chemotherapy only. The results showed that the overall response rate and median progression-free survival time were 78%and 11.5 months in Group A, 41%and 8 months in Group B, respectively (P 0.05). The interventional complications in Group A included 5 patients with postoperative pneumothorax and 4 patients with hemoptysis. No patients had radiation pneumonia, radiation esophagitis or esophagotracheal fistula. Chemotherapy treatment-related toxicities were not significantly different between the two groups. The relief of tumor-associated symptoms including cough, hemoptysis, chest pain, and short breath was found in both groups, without statistical difference in remission rates between Groups A and B (P >0.05). In conclusion, 125I brachytherapy combined with chemotherapy proved to be safe and effective for treating advanced NSCLC with few complications. It improves local control rate and prolongs the progression-free survival time.

    Objective: To observe the efficacy and safety of cetuximab combined with chemotherapy in advanced non-small-cell lung cancer (NSCLC), and to investigate the association of status of K-RAS gene mutation and epidermal growth factor receptor (EGFR) genotype with clinical outcome.Methods: Between Jan. 2006 and Sep. 2009, nineteen patients with advanced NSCLC received cetuximab (≥4 weeks) combined with chemotherapy in Department of Thoracic Oncology at Beijing Cancer Hospital. Response, survival and toxicity were retrospectively assessed, epidermal growth factor receptor (EGFR) protein expression was evaluated by ELISA Kit. The status of K-RAS gene mutation was tested by PCR-RFLP and EGFR gene amplification was measured by EGFR fluorescence in situ hybridization (FISH).Results: Partial response(PR) was observed in 26.3%(5/19) of the patients and stable disease(SD) in 52.6%(10/19). Median progression free survival(PFS) was 6 months (95% CI: 3.6-8.4). Median overall survival (MST) and 1-year survival rate(SR) were 10.6 months (95% CI: 6.6-14.6) and 47.6%, respectively. Mild or moderate skin rash was the most common toxicity related with cetuximab. K-RAS gene mutation, EGFR protein level and amplification have little correlation with prognosis.Conclusion: Cetuximab combined with chemotherapy was tolerable and the skin rash related with cetuximab was mild to moderate. Cetuximab may prolong survival of the patients who failed to previous chemotherapy.

    Full Text Available Background: Lung cancer is one of the leading causes of cancer-related death. At the time of diagnosis, more than half of the patients will have disseminated disease and, yet, diagnosing can be challenging. New methods are desired to improve the diagnostic work-up. Exosomes are cell-derived vesicles displaying various proteins on their membrane surfaces. In addition, they are readily available in blood samples where they constitute potential biomarkers of human diseases, such as cancer. Here, we examine the potential of distinguishing non-small cell lung carcinoma (NSCLC patients from control subjects based on the differential display of exosomal protein markers. Methods: Plasma was isolated from 109 NSCLC patients with advanced stage (IIIa–IV disease and 110 matched control subjects initially suspected of having cancer, but diagnosed to be cancer free. The Extracellular Vesicle Array (EV Array was used to phenotype exosomes directly from the plasma samples. The array contained 37 antibodies targeting lung cancer-related proteins and was used to capture exosomes, which were visualised with a cocktail of biotin-conjugated CD9, CD63 and CD81 antibodies. Results: The EV Array analysis was capable of detecting and phenotyping exosomes in all samples from only 10 µL of unpurified plasma. Multivariate analysis using the Random Forests method produced a combined 30-marker model separating the two patient groups with an area under the curve of 0.83, CI: 0.77–0.90. The 30-marker model has a sensitivity of 0.75 and a specificity of 0.76, and it classifies patients with 75.3% accuracy. Conclusion: The EV Array technique is a simple, minimal-invasive tool with potential to identify lung cancer patients.

    Full Text Available Background and objective As there is a sharp increase in the incidence of lung cancer in women in recent years, it has brought broad concerns with its unique clinical and epidemiological characteristics and better prognosis. The aim of this study is to analyze the clinical data of women with advanced non-small cell lung cancer (NSCLC retrospectively to explore the prognostic factors. Methods Clinical data of 541 female patients with advanced NSCLC were collected and followed up till death. The primary endpoint is overall survival (OS. SPSS 11.0 statistical analysis software was used for univariate and multivariate analysis. Results The mean age is 59 years (20 years-86 years, adenocarcinoma account for 80.2% (434/541. The median OS was 15 months (95%CI: 13.87-16.13, and 1, 2, 5-year survival rates were 58.8%, 23.7% and 3.20% respectively. Univariate analysis showed that clinical stage, ECOG score, weight loss, clinical symptoms, liver/bone/brain metastasis and received more than one chemotherapy regimen, good response to the first-line chemotherapy, EGFR-TKI targeted therapy and radiotherapy treatment were significantly correlated with the OS and survival rate (P < 0.05. Combined with multivariate analysis, weight loss before treatment, ECOG score, received EGFR-TKI targeted therapy and response to first-line chemotherapy were independent prognostic factor for survival (P < 0.05. Conclusion There is a higher percentage of adenocarcinoma in female NSCLC. Weight loss before treatment, ECOG score, EGFR-TKI targeted therapy and response to first-line chemotherapy may become independent prognostic factors for survival of female patients with advanced NSCLC.

    Full Text Available We aimed to establish a laboratory prognostic index (LPI in advanced non-small cell lung cancer (NSCLC patients based on hematologic and biochemical parameters and to analyze the predictive value of LPI on NSCLC survival.The study retrospectively reviewed 462 patients with advanced NSCLC diagnosed between 2000 and 2010 in a single institution. We developed an LPI that included serum levels of white blood cells (WBC, lactate dehydrogenase (LDH, albumin, calcium, and alkaline phosphatase (ALP, based on the results of a Cox regression analysis. The patients were classified into 3 LPI groups as follows: LPI 0: normal; LPI 1: one abnormal laboratory finding; and LPI 2: at least 2 abnormal laboratory findings.The median follow up period was 44 months; the median overall survival (OS and median progression-free survival (PFS were 11 and 6 months, respectively. A multivariate analysis revealed that the following could be used as independent prognostic factors: an Eastern Cooperative Oncology Group performance status score (ECOG PS ≥2, a high LDH level, serum albumin 10.5 g/dL, number of metastases>2, presence of liver metastases, malignant pleural effusion, or receiving chemotherapy ≥4 cycles. The 1-year OS rates according to LPI 0, LPI 1, and LPI 2 were 54%, 34%, and 17% (p<0.001, respectively and 6-month PFS rates were 44%, 27%, and 15% (p<0.001, respectively. The LPI was a significant predictor for OS (Hazard Ratio (HR: 1.41; 1.05-1.88, p<0.001 and PFS (HR: 1.48; 1.14-1.93, p<0.001.An LPI is an inexpensive, easily accessible and independent prognostic index for advanced NSCLC and may be helpful in making individualized treatment plans and predicting survival rates when combined with clinical parameters.

  7. Dose escalation for unresectable locally advanced non-small cell lung cancer: end of the line?

    2016-02-01

    Radiation Therapy Oncology Group (RTOG) 0617 was a randomized trial that investigated both the impact of radiation dose-escalation and the addition of cetuximab on the treatment of non-small cell lung cancer (NSCLC). The results of RTOG 0617 were surprising, with the dose escalation randomization being closed prematurely due to futility stopping rules, and cetuximab ultimately showing no overall survival benefit. Locally advanced unresectable NSCLC has conventionally been treated with concurrent chemoradiation. Though advances in treatment technology have improved the ability to deliver adequate treatment dose, the foundation for radiotherapy (RT) has remained the same since the 1980s. Since then, progressive studies have sought to establish the safety and efficacy of escalating radiation dose to loco-regional disease. Though RTOG 0617 did not produce the anticipated result, much interest remains in dose escalation and establishing an explanation for the findings of this study. Cetuximab was also not found to provide a survival benefit when applied to an unselected population. However, planned retrospective analysis suggests that those patients with high epidermal growth factor receptor (EGFR) expression may benefit, suggesting that cetuximab should be applied in a targeted fashion. We discuss the results of RTOG 0617 and additional findings from post-hoc analysis that suggest that dose escalation may be limited by normal tissue toxicity. We also present ongoing studies that aim to address potential causes for mortality in the dose escalation arm through adaptive or proton therapy, and are also leveraging additional concurrent systemic agents such as tyrosine kinase inhibitors (TKIs) for EGFR-activating mutations or EML4-ALK rearrangements, and poly (ADP-ribose) polymerase (PARP) inhibitors.

    Full Text Available Cisplatin-based chemotherapy is the standard treatment for advanced non-small cell lung cancer (NSCLC. Many novel drugs have been used in combination with cisplatin in this setting. Of these drugs, gemcitabine is reported to have a high response rate and acceptable toxicity. The aim of this study was to evaluate the efficacy and safety of gemcitabine and cisplatin combination. Twentythree patients with NSCLC were enrolled from January 2001 till September 2003. All of them were confirmed by histology and were in advanced stage, i.e. stage IIIB or stage IV. Cisplatin with the dose of 70 mg/m2 was given every 21 days, in combination with gemcitabine at a dose of 1250 mg/m2 administered on days 1, 8 of a 21-day cycle. Of the 23 patients, 1 showed complete remission, 5 achieved partial remission and 7 had stable disease and 2 patients showed progressive disease, 8 patients were not evaluable for response. The overall response in 15 evaluable patients was 40% (95% CI., median survival was 13.5 months (95% CI, 3.5-27.4 months, and median progression free survival was 11 months (95% CI, 1.04-20.9 months. Hematological toxicity’s included anemia, neutropenia and thrombocytopenia. Non-hematological toxicities included nausea/vomiting, peripheral neuropathy, skin rashes, mild renal impairment and one case of acute respiratory distress syndrome;another case developed transient acute psychosis. The regimen of combined gemcitabine with cisplatin is safe and effective and well tolerated in patients. In this combination, a lower dose of cisplatin seems to have an efficacy similar to that seen in previous reports.

    2012-04-01

    Full Text Available The incorporation of individualized molecular therapeutics into routine clinical practice for both non-small cell lung cancer (NSCLC and melanoma are amongst the most significant advances of the last decades in medical oncology. In NSCLC activating somatic mutations in exons encoding the tyrosine kinase domain of the Epidermal Growth Factor Receptor (EGFR gene have been found to be predictive of a response to treatment with tyrosine kinase inhibitors (TKI, erlotinib or gefitinib. More recently the EML4-ALK fusion gene which occurs in 3–5% of NSCLC has been found to predict sensitivity to crizotinib an inhibitor of the anaplastic lymphoma kinase (ALK receptor tyrosine kinase. Similarly in melanoma, 50% of cases have BRAF mutations in exon 15 mostly V600E and these cases are sensitive to the BRAF inhibitors vemurafenib or dabrafenib. In a Phase III study of advanced melanoma cases with this mutation vemurafenib improved survival from 64% to 84% at 6 months, when compared with dacarbazine. In both NSCLC and melanoma clinical benefit is not obtained in patients without these genomic changes, and moreover in the case of vemurafenib the therapy may theoretically induce proliferation of cases of melanoma without BRAF mutations. An emerging clinical challenge is that of acquired resistance after initial responses to targeted therapeutics. Resistance to the TKI’s in NSCLC is most frequently due to acquisition of secondary mutations within the tyrosine kinase of the EGFR or alternatively activation of alternative tyrosine kinases such as C-MET. Mechanisms of drug resistance in melanoma to vemurafenib do not involve mutations in BRAF itself but are associated with a variety of molecular changes including RAF1 or COT gene over expression, activating mutations in RAS or increased activation of the receptor tyrosine kinase PDGFRβ. Importantly these data support introducing re-biopsy of tumors at progression to continue to personalize the choice of

    During the past 15 years, treatment of stage IIIA (N2) non-small cell lung cancer has evolved considerably because of improvements in patients selection, staging, and combined modality therapy. Results of several clinical trials suggest that induction chemotherapy or chemoradiation and surgical resection is superior to surgery alone. However, the optimal induction regimen has not been defined. An intergroup trial is also underway to determine whether chemoradiation and surgical resection leads to better survival than chemotherapy and radiation alone. Future studies will assess ways to combine radiation and novel chemotherapeutic agents, and will identify molecular abnormalities that predict response to induction therapy.

  13. Optimal pharmacotherapeutic strategies for elderly patients with advanced non-small cell lung cancer.

    Increases in both life expectancy and cancer incidence with age result in a significant rise in lung cancer rates among elderly patients, with a median age at diagnosis of between 63 and 70 years. However, elderly patients are under-represented in clinical trials and generally receive suboptimal treatment, mainly because of fears about increased toxicity of chemotherapy. Indeed, physiological modification of renal and haematopoietic functions with age together with co-morbidity and associated polypharmacy may alter the metabolism of chemotherapy drugs, resulting in greater toxicity. Moreover, performance status (PS), the main prognostic factor in younger patients, does not correlate well with geriatric indexes such as activities of daily living, cognition and physical performance, and comprehensive geriatric assessment is important in elderly patients. Until 2010, based on the small number of clinical trials designed for elderly patients, monotherapy was the recommended treatment for those with advanced non-small cell lung cancer (NSCLC), whereas for fit younger patients, a platinum-based doublet was and continues to be the recommended first-line therapy. However, at the plenary session of the 2010 Annual Meeting of the American Society of Clinical Oncology, results were presented from a randomized controlled trial conducted by the French Intergroup of Thoracic Oncology that demonstrated that in PS 0-2 patients aged≥70 years with advanced NSCLC, monthly carboplatin with weekly paclitaxel resulted in significantly longer survival than single-agent therapy (vinorelbine or gemcitabine). It should be noted that even in a priori unfavourable prognostic subgroups (patients with a PS score of 2, those aged>80 years or those with an activities of daily living scale score of nihilism in the treatment of elderly patients with advanced NSCLC. Such patients should be evaluated carefully by geriatric indexes and, if they have a PS score of 0-2, may be treated with platinum

    Full Text Available Recently, researchers have been increasingly finding coagulation disorders are commonly the first sign of malignancy. It has now been established that cancer development leads to an increased risk of thrombosis, and conversely, excessive activation of blood coagulation profoundly influences cancer progression. In patients with lung cancer, a sustained stimulation of blood coagulation takes place. Cancer cells trigger coagulation through expression of tissue factor, and affect coagulation through expression of thrombin, release of microparticles that augment coagulation and so on. Coagulation also facilitates tumour progression through release of platelet granule contents, inhibition of natural killer cells and recruitment of macrophages. Non-small cell lung cancer (NSCLC accounts for about 80%-85% of all lung malignancies. In the present review, we summarized the newly updated data about the physiopathological mechanisms of various components of the clotting system in different stages of carcinogenesis in NSCLC.

    Full Text Available Lung cancer is severely threatening human health. In recent years, the treatment for lung adenocarcinoma has made a great progress, targeted therapy has been widely applied in clinic, and benefits amount of patients. However, in squamous cell lung cancer, the incidence of epidermal growth factor receptor (EGFR gene mutant and ALK fusion gene are low,and targeted therapy like Tarceva and crizotinib, can hardly work. Since the fibroblast growth factors (fibroblast growth factor, FGF pathway is considered to be related to tumor cell proliferation, metastasis and angiogenesis, more and more researches proved the amplification of fibroblast growth factor receptor (FGFR in squamous cell lung cancer. Experiments in vivo and in vitro found that blocking FGF pathway could reduce the proliferation of tumor cells and inhibit metastasis. The FGF pathway might be a new target for treatment of squamous cell lung cancer. This article reviews the effect of FGFR in tumorigenesis,as well as the prospect as a therapeutic target in non-small cell lung cancer.

  18. The cost of treating advanced non-small cell lung cancer: estimates from the chinese experience.

    Directory of Open Access Journals (Sweden)

    Xiaohui Zeng

    Full Text Available BACKGROUND: Because of the potentially significant economic burden of healthcare costs associated with many diseases, it is critical that regulatory and medical insurance organisations collect and utilise data on the cost-effectiveness of care provision to make rational policy decisions. However, little is known about healthcare costs in China. METHODOLOGY/PRINCIPAL FINDINGS: Based on health expenditure data for 253 cases of advanced non-small cell lung cancer (NSCLC registered at the Second Xiangya Hospital of Central South University in China between 2006 and 2010, the cost of care provision was analysed. The monthly and aggregate annual medical costs were estimated for patients who were in either a progression-free state (PFS or a disease-progression state (DPS. Monthly healthcare costs accumulated during the terminal 3 months were collected separately. The mean cost of treatment for PFS and DPS patients over one year was approximately US$11,566 and $14,519, respectively. The monthly costs for all patients were higher initially than in the subsequent months (PFS: $2,490; DPS: $2,503. For PFS patients, healthcare expenditures stabilised after the 7th month, with a mean monthly medical expenditure of $82.49. For DPS patients, expenditures stabilised after the 9th month, and the mean expenditure during the 9th month was $307.9. Medical care costs in the three successive months prior to death were $3,754, $5,829 and $7,372, respectively. CONCLUSIONS/SIGNIFICANCE: The economic evaluation of health care technologies is becoming ever more important in China, especially in disease areas for which new and expensive therapies are being introduced on a regular basis. This is first paper to present empirically estimated China-specific costs associated with the treatment of NSCLC. The cost estimates are presented in a format that is specifically intended to inform cost-effectiveness analyses of treatments for NSCLC, and hence, contribute to the more

  19. The role of prophylactic cranial irradiation in regionally advanced non-small cell lung cancer. A Southwest Oncology Group Study

    Lung cancer is the most common malignant disease in the United States. Only the few tumors detected very early are curable, but there has been some progress in the management of more advanced non-small cell lung cancer, particularly in regionally inoperable disease. Prevention of central nervous system relapse is an important issue in this group of patients because brain metastases ultimately develop in 20% to 25% of them. Seventy-three patients with regionally advanced non-small cell lung cancer were entered into a Phase II trial of neutron chest radiotherapy sandwiched between four cycles of chemotherapy including cisplatin, vinblastine, and mitomycin C. Prophylactic cranial irradiation was administered concurrently with chest radiotherapy (3000 cGy in 10 fractions in 15 patients; 3600 cGy in 18 fractions in the remaining 50 patients). Patients underwent computed tomographic scan of the brain before treatment and every 3 months after treatment. The initial overall response rate was 79%, but 65 of the 73 patients have subsequently died of recurrent disease. Median follow-up is 9 months for all 73 patients and 26 months for eight long-term survivors. No patient who completed the prophylactic cranial irradiation program had clinical or radiologic brain metastases. Toxic reactions to prophylactic cranial irradiation included reversible alopecia in all patients, progressive dementia in one patient, and possible optic neuritis in one patient. Both of these patients received 300 cGy per fraction of irradiation. The use of prophylactic cranial irradiation has been controversial, but its safety and efficacy in this trial supports its application in a group of patients at high risk for central nervous system relapse. Further evaluation of prophylactic cranial irradiation in clinical trials for regionally advanced non-small cell lung cancer is warranted

    Full Text Available Background and objective Icotinib hydrochloride is the third single target EGFR-TKI used in clinical treatment of advanced non-small cell lung cancer (NSCLC. Clinical research reports on its efficacy and survival in patients with Recurrent Advanced NSCLC are still little.The aim of this study is to evaluate the efficacy and survival of Icotinib hydrochloride for patients with advanced non-small cell lung cancer who failed to previous chemotherapy and explore the association of clinical features with the efficacy and survival. Methods The clinical data of 60 NSCLC patients referred to the Beijing Chest Hospital, Capital Medical University from March 2009 to July 2012 were retrospectively analyzed. Results The overall response rate (ORR was 45.0% and the disease control rate (DCR was 80.0%. The median progression-free survival (PFS time was 6.7 months. RR and PFS in female were superior to male (P=0.014, 0.013, respectively. RR, DCR in 2nd-line subgroup were superior to ≥3rd-line subgroup (P=0.020, 0.024, respectively. RR, DCR and PFS in EGFR mutation carriers were significantly superior to wild-type patients (P=0.006, <0.001, 0.002, respectively . There was no statistical difference in RR and PFS between those age <65 and ≥65 or PS<2 and PS≥2. There was no statistical difference in RR and DCR between exon 19 deletion and exon 21 mutations, while the former had much longer PFS (P=0.020. EGFR mutation and exon 19 deletion are the independent prognostic factors to significantly improve the PFS (P=0.009, 0.012, respectively. The side effects were generally mild and consisted of rash and diarrhea. Conclusion Icotinib hydrochloride is effective especially in EGFR mutation carriers and well tolerated in patients with recurrent advanced non-small-cell lung cancer.

    Full Text Available Abstract Treatment of non-small-cell lung cancer is dependent on disease stage. For patients with metastasis or locally advanced disease, the importance of finding therapeutic schemes that may benefit this population is important. This review discusses therapeutic options for first- and second-line treatment in patients with advanced non-small-cell lung cancer. According to current data, the combination of two cytotoxic agents is the optimum first-line treatment for patients with non-small-cell lung cancer and performance status of 0–1. Addition of bevacizumab has shown to provide an even longer survival and to increase response rate. Within the first-line setting, erlotinib appears to be effective in the treatment of elderly patients who would not derive a benefit from standard chemotherapy or those refusing standard chemotherapy. The administration of erlotinib as first-line maintenance therapy is being assessed. There are currently three drugs approved for second-line treatment of patients with advanced non-small-cell lung cancer after failure of first-line chemotherapy. These drugs have proven to be effective in phase III trials. In the phase III trial BR.21 study, the response rate was 8.9% in the erlonitib group, and less than 1% in placebo; median response duration was 7.9 months and 3.7 months, respectively; and the median survival was 6.7 months and 4.7 with erlotinib and placebo, respectively. One-year survival was 31% and 21% with erlotinib and placebo, respectively. In addition, the BR.21 trial revealed that significantly greater improvements in overall quality of life and in both physical and emotional functioning were observed in the erlotinib arm as compared with the placebo arm. Erlotinib is not significantly associated with hematologic adverse effects. Erlotinib is administered orally, and does not require concomitant administration of other drugs, thus causing patients less inconvenience. Analysis of data from different

    2011-01-01

    Full Text Available Gefitinib is an oral, reversible, tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR that plays a key role in the biology of non small cell lung cancer (NSCLC. Phase I studies indicated that the recommended dose of gefitinib was 250 mg/day. Rash, diarrhea, and nausea were the most common adverse events. The positive results obtained in early phase 2 clinical trials with gefitinib were not confirmed in large phase 3 trials in unselected patients with advanced NSCLC. The subsequent discovery that the presence of somatic mutations in the kinase domain of EGFR strongly correlates with increased responsiveness to EGFR tyrosine kinase inhibitors prompted phase 2 and 3 trials with gefitinib in the first line-treatment of EGFR-mutated NSCLC. The results of these trials have demonstrated the efficacy of gefitinib that can be now considered as the standard first-line treatment of patients with advanced NSCLC harbouring activating EGFR mutations.

    The emergence of immune checkpoint inhibitors marked an important advancement in the development of cancer therapeutics. Pembrolizumab is a selective humanized IgG4 kappa monoclonal antibody that inhibits the programmed death-1 (PD-1) receptor, an integral component of immune checkpoint regulation in the tumor microenvironment. The drug is currently approved by the Food and Drug Administration for the treatment of advanced melanoma and metastatic squamous and nonsquamous non-small cell lung cancer (NSCLC). Several published studies demonstrate that single-agent pembrolizumab is safe and has efficacy in patients with NSCLC. Many ongoing protocols are investigating the role of pembrolizumab in combination with other agents in lung cancer and various other cancer types. We review the available data on pembrolizumab in NSCLC and examine the role of potential predictive biomarkers of response to therapy.

    Objective: To assess the therapeutic effectiveness of preoperative neoadjuvant chemotherapy using a combination of paclitaxel and carboplatin on local advanced non-small cell lung cancer (NSCLC). Methods: Twenty-five patients with advanced NSCLC were treated with paclitaxel and carboplatin for 2 to 4 cycles before undergoing tumor resection and then postoperative chemotherapy/radiotherapy therapy for 2 to 4 cycles. Results: Following neoadjuvant chemotherapy, the most prominent side-effect was bone marrow restraint. The overall response rate of preoperative chemotherapy was 56%. The mean survival time was 26.5 months, with 1-, 2- and 5-year survival rates of 55%, 25%, and 16%, respectively. All NSCLC patients survived the perioperative period. Conclusion: Preoperative neoadjuvant chemotherapy combining paclitaxel and carboplatin produced minimal side-effect while increasing the probability that advanced NSCLC patients would be able to undergo surgery thus improving their prognosis.

Gefitinib, a tyrosine kinase (TK inhibitor of epidermal growth factor receptor (EGFR, displays anti-tumor activity. The present data regarding first-line treatment with single agent gefitinib against non-small-cell lung cancer (NSCLC in Chinese population are not sufficient. Purpose To assess the efficacy and toxicity of gefitinib in Chinese patients with advanced non-small-cell lung cancer (NSCLC, a study of single agent treatment with gefitinib in Chinese patients was conducted. Methods 45 patients with advanced NSCLC were treated with gefitinib (250 mg daily until the disease progression or intolerable toxicity. Results Among the 45 patients, 15 patients achieved partial response (PR, 17 patients experienced stable disease (SD, and 13 patients developed progression disease (PD. None of the patients achieved complete response (CR. The tumor response rate and disease control rate was 33% and 71.1%, respectively. Symptom remission rate was 72.5%, and median remission time was 8 days. Median overall survival and median progression-free survival was 15.3 months and 6.0 months, respectively. The main induced toxicities by gefitinib were skin rash and diarrhea (53.3% and 33.3%, respectively. The minor induced toxicities included dehydration and pruritus of skin (26.7% and 22.2%, respectively. In addition, hepatic toxicity and oral ulceration occurred in few patients (6.7% and 4.4%2, respectively. Conclusions Single agent treatment with gefitinib is effective and well tolerated in Chinese patients with advanced NSCLC.

    ABSTRACT Following concurrent radio-chemotherapy or first-line chemotherapy for advanced non-small cell lung cancer(NSCLC), continuous maintenance therapy given to patients with stable disease (SD) and follow-up treatment is called consolidation therapy. Concerning NSCLC patients with a non-operable dry Stage-ⅢB (N3) disease, I.e. Contra-lateral mediastinal and hilar lymph node, or homolateral/contra-lateral scalene and Troisier sign, a 2 or 3-course of standard-dosage Taxotere consolidation therapy can be performed after concurrent radio-chemotherapy. In pursuance of evidence-based medicine (EBM), low-dose Taxoteremaintenance therapy, and biological targeted therapy of patients with appropriate symptoms are suitable for second-line therapy for moist of the Stage-ⅢB (malignant pleural effusion) and Ⅳpatients.

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    @@ Platinum-based chemotherapy can improve the survival and quality of life of patients with locally advanced and metastatic lung cancer. Second-line docetaxel monotherapy can improve overall survival following the failure of first line chemotherapy. However, many limiting factors such as poor performance status, advanced age, adverse effects of chemotherapy and reluctance to receive cytotoxic chemotherapeutic agents render patients unable to accept chemotherapy. Furthermore, for patients who have failed second-line chemotherapy treatment options are often limited to best support care or palliative radiotherapy. 1 Gefitinib (Iressa) is a HER1/EGFR (epidermal growth factor receptor)- tyrosine kinase inhibitor approved in a number of countries including the US, Japan and recently China for the treatment of patients with non-small cell lung cancer (NSCLC), who have failed platinum/docetaxel-based first line and second line chemotherapy. 2,3 Current data show heterogeneity in response to gefitinib among people of different ethnic origin, but there is very little data concerning the safety and efficacy of gefitinib in Chinese patients. This paper aims to summarize the safety and efficacy data for gefitinib 250 mg treatment in Chinese NSCLC patients at Peking Union Medical College Hospital who received gefitinib as part of an Expanded Access Programme.

  9. Role of erlotinib in first-line and maintenance treatment of advanced non-small-cell lung cancer

    International Nuclear Information System (INIS)

    Erlotinib hydrochloride (Tarceva®) is a member of a class of small molecule inhibitors that targets the tyrosine kinase domain of the epidermal growth factor receptor (EGFR), with anti-tumor activity in preclinical models. Erlotinib represents a new-generation of agents known as “targeted therapies” designed to act upon cancer cells by interfering with aberrant specific activated pathways needed for tumor growth, angiogenesis and cell survival. Since its approval in November 2004 for the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) after the failure of at least one prior chemotherapy regimen and with a view to improving patients’ outcomes and prevent symptoms, the scientific community has evaluated the potential role of erlotinib in other scenarios such as in maintenance therapy and, in first-line setting for a selected population based on biological markers of response such as mutations of the EGFR. The convenient once-a-day pill administration and the good toxicity profile of erlotinib make it a reasonable candidate for testing in this context. This report provides a review of the role of erlotinib therapy in advanced NSCLC. It summarizes current data and perspectives of erlotinib in upfront treatment and maintenance for advanced NSCLC as well as looking at candidate biomarkers of response to these new targeted-agents

    To analyze the response, toxicity, patterns of failure and survival rate of patients with locally advanced non-small cell lung cancer who were treated with concurrent chemoradiotherapy with weekly paclitaxel. Twenty-three patients with locally advanced non-small cell lung cancer patients who received radical chemoradiotherapy from October 1999 to September 2004 were included in this retrospective study. Patients received total 55.4 {approx} 64.8 (median 64.8) Gy (daily 1.8 Gy per fraction, 5 days per weeks) over 7 {approx} 8 weeks. 50 or 60 mg/m{sup 2} of paclitaxel was administered on day 1, 8, 15, 22, 29 and 36 of radiotherapy. Four weeks after the concurrent chemoradiotherapy, three cycles of consolidation chemotherapy consisted of paclitaxel 135 mg/m{sup 2} and cisplatin 75 mg/m{sup 2} was administered every 3 weeks. Of the 23 patients, 3 patients refused to receive the treatment during the concurrent chemoradiotherapy. One patient died of bacterial pneumonia during the concurrent chemoradiotherapy. Grade 2 radiation esophagitis was observed in 4 patients (17%). Sixteen patients received consolidation chemotherapy. During the consolidation chemotherapy, 8 patients (50%) experienced grade 3 or 4 neutropenia and one of those patients died of neutropenic sepsis. Overall response rate for 20 evaluable patients was 90% including 4 complete responses (20%) and 14 partial responses (70%). Among 18 responders, 9 had local failure, 3 had local and distant failure and 2 had distant failure only. Median progression-free survival time was 9.5 months and 2-year progression-free survival rate was 19%. Eleven patients received second-line or third-line chemotherapy after the treatment failure. The median overall survival time was 21 months. 2-year and 5-year survival rate were 43% and 33%, respectively. Age, performance status, tumor size were significant prognostic factors for progression-free survival. Concurrent chemoradiotherapy with weekly paclitaxel revealed high

    International Nuclear Information System (INIS)

    Objective: To retrospectively analyze the outcome of locally advanced non-small cell lung cancer patients treated with radiotherapy and chemoradiotherapy. Methods: 289 patients who were treated either by radiotherapy alone (168 patients) or radiotherapy plus chemotherapy (121 patients) from Dec. 1999 to Dec. 2002 were entered into the database for analysis. Pathological types: squamous cancer (152), adenocarcinoma(74), squamoadenocarcinoma(2) and other types (2). 24 showed cancer unclassificable and 35 were diagnosed without pathological proof. Stages: 74 had III A and 215 III B stage disease. Among the 121 patients treated with combined modality, 24 were treated with concurrent chemoradiotherapy, 78 radiotherapy after chemotherapy(C + R), and 19 radiotherapy followed by chemotherapy(R + C). In patients treated by concurrent chemoradiotherapy or C + R, 38 received consolidation chemotherapy after induction treatment. Results: The 1-, 3-, 5-year overall survival, and the median survival were: 45% , 16% , 8%, and 16.2 months for all patients; 57%, 27%, 11%, and 21.7 months for stage IIIA; 41%, 12%, 7%, and 15.3 months for IIIB. By logrank test, clinical stage, KPS performance, tumor volume, hemoglobin level before treatment, consolidation chemotherapy, radiation dose, and response to treatment showed statistically dramatic impact on overall survival. The overall survival rate and median survival time were slightly higher in the combined group than in the radiotherapy alone group, but the difference is statistically insignificant. In Cox multivariable regression, stage and consolidation chemotherapy were independent prognostic factors; KPS performance, radiation dose, and response to treatment were at the margin of statistical significance. Esophagitis and pneumonitis of Grade II or higher were 24% and 8%, respectively. Failure sites included in the thorax(41%), outside of thorax(48%), and both in and outside the thorax(11%). There was no difference between the

    2014-06-01

    Full Text Available Radiation dose in the setting of chemo-radiation for locally advanced non-small cell lung cancer (NSCLC has been historically limited by the risk of normal tissue toxicity and this has been hypothesized to correlate with the poor results in regard to local tumor recurrences. Dose escalation, as a means to improve local control, with concurrent chemotherapy has been shown to be feasible with three-dimensional conformal radiotherapy in early phase studies with good clinical outcome. However, the potential superiority of moderate dose escalation to 74 Gy has not been shown in phase III randomized studies. In this review, the limitations in target volume definition in previous studies; and the factors that may be critical to safe dose escalation in the treatment of locally advanced NSCLC, such as respiratory motion management, image guidance, intensity modulation, FDG-PET incorporation in the treatment planning process, and adaptive radiotherapy, are discussed. These factors, along with novel treatment approaches that have emerged in recent years, are proposed to warrant further investigation in future trials in a more comprehensive and integrated fashion.

    Results: A total of 72 patients who had received third-line or higher chemotherapy were included in the analysis. The median age of patients was 49 years (range 41-76, and there were 13 (18.1% women and 59 (81.9% men. Estimated median survival was 26 months. Moreover, overall survival was significantly longer in patients for whom disease control was achieved after second-line chemotherapy compared to those with disease progression (34 vs. 17 months, respectively. Survival after third-line treatment was significantly longer in the group with Eastern Cooperative Oncology Group (ECOG performance status 0-1 at the beginning of third-line therapy compared to patients with a status of 2-3. Conclusions: In patients with advanced stage NSCLC, administration of third-line and higher systemic chemotherapy may be associated with increase in overall survival. Furthermore, greater increases in overall survival were also observed in patients for whom disease control was achieved after second-line therapy and in those with ECOG performance status of 0-1 before third-line treatment.

  17. Daily etoposide and cisplatin during thoracic radiotherapy for patients with locally advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Purpose: A phase I/II trial was performed to investigate the toxicity and potential efficacy of delivering two radiosensitizing chemotherapeutic agents (cisplatin and etoposide) on a daily basis during twice daily thoracic radiotherapy for patients with locally advanced non-small cell lung cancer. Methods: Patients were eligible for this trial if they had unresectable or incompletely resected biopsy-proven stage IIIA or IIIB non-small cell lung carcinoma. However, patients with contralateral hilar or supraclavicular disease were excluded. Patients were required to have an ECOG performance status of 0-2 and ≤10% weight loss during the preceding three months. Thoracic radiation treatment (TRT) was delivered as accelerated hyperfractionated TRT with 150 cGy given twice daily beginning on a Monday. Patients received a two-week break between two courses of 3000 cGy (total dose:6000cGy). Patients received etoposide (25 mg/m2 po) on days 1-12 and cisplatin (3 mg/m2 IV) on days 1-5 and 8-12 of each course of TRT. Two weeks following the completion of TRT patients began two cycles (q 28d) of etoposide (25 mg/m2, po, d1-21) and cisplatin (50 mg/m2 IV, d1). Patients were seen in followup at 2 months following the completion of therapy and subsequently at 3 month intervals for the first year. Results: Seventeen patients were entered on the trial and the median followup was 11 months. Of the 17 patients, 13 had evaluable disease and 4 had measurable disease; 16 were deemed unresectable and one had an incomplete resection; 6 had squamous cell carcinomas and 11 had non-squamous cell carcinomas; 5 had primary tumors greater than 6 cm, 9 were 3-6 cm and 3 were <3 cm; 14 had less than 5% weight loss and 3 had 5-10% weight loss; 9 had stage IIIA disease and 8 had IIIB disease. The most common hematologic toxicity was leukopenias: 4 patients had grade 3 and 1 had grade 4 toxicity. No grade 3 or greater thrombocytopenia was observed. There were 6 grade 3 nonhematologic toxicities

    Full Text Available OBJECTIVE: To investigate the clinical significance of the expression of MHC class I chain-related gene A (MICA in patients with advanced non-small cell lung cancer and explore the relationship between MICA expression and the efficacy of cytokine-induced killer cell (CIK therapy for treating advanced non-small cell lung cancer. METHODS: We obtained data on 222 patients with advanced non-small cell lung cancer, including data on MICA expression, age, gender, ECOG score, pathological type, stage, treatment history (including 38 patients who were given autologous CIK cell infusion, and overall survival (OS. MICA expression in lung cancer tissue was evaluated by immunohistochemical staining. Analyses of MICA expression, and CIK therapy association with survival outcomes were performed using Cox proportional models, Kaplan-Meier methods, and the log-rank test. RESULT: s MICA was expressed in both membrane and cytoplasm. MICA expression correlated with the stage of lung cancer, ECOG score, gender and age. Multivariate COX regression analysis showed that the expression of MICA was an independent prognostic factor of advanced non-small cell lung cancer (p = 0.002. In subgroup analysis, we divided the 222 patients into CIK and control groups. In the CIK group, the medium OS (mOS of patients with a high expression of MICA was longer than in those with low expression of MICA (27 months vs. 13 months. In the control group, the mOS in patients with a high expression of MICA was shorter than in patients with low MICA expression (9 months vs. 18 months. COX regression analysis showed that the MICA expression affects the effect of CIK therapy (p<0.0001. CONCLUSION: 1 The high expression of MICA is one of the indicators of a poor prognosis for advanced non-small cell lung cancer patients. 2 The high expression of MICA might be one of the predictive factors for successful CIK therapy.

    Lung cancer is the principal cause of cancer-related mortality in the developed world, accounting for almost one-quarter of all cancer deaths. Traditional treatment algorithms have largely relied on histologic subtype and have comprised pragmatic chemotherapy regimens with limited efficacy. However, because our understanding of the molecular basis of disease in non-small cell lung cancer (NSCLC) has improved exponentially, it has become apparent that NSCLC can be radically subdivided, or molecularly characterized, based on recurrent driver mutations occurring in specific oncogenes. We know that the presence of such mutations leads to constitutive activation of aberrant signaling proteins that initiate, progress, and sustain tumorigenesis. This persistence of the malignant phenotype is referred to as "oncogene addiction." On this basis, a paradigm shift in treatment approach has occurred. Rational, targeted therapies have been developed, the first being tyrosine kinase inhibitors (TKIs), which entered the clinical arena > 10 years ago. These were tremendously successful, significantly affecting the natural history of NSCLC and improving patient outcomes. However, the benefits of these drugs are somewhat limited by the emergence of adaptive resistance mechanisms, and efforts to tackle this phenomenon are ongoing. A better understanding of all types of oncogene-driven NSCLC and the occurrence of TKI resistance will help us to further develop second- and third-generation small molecule inhibitors and will expand our range of precision therapies for this disease.

    Objective: The purpose of this study was to assess the curative effect and adverse reaction of preoperative induction chemotherapy with gemcitabine combined with cisplatin for locally advanced non-small cell lung cancer (NSCLC). Methods: This prospective randomized controlled trial included 115 patients with locally advanced NSCLC were randomly divided into experimental and control groups and were treated from January 2007 to January 2010. The experimental group of 63 cases was treated with two cycles of induction chemotherapy before operation, radical surgery had been performed about three weeks after completion of chemotherapy, followed by received two cycles of chemotherapy. And the control group (52 cases) was treated at first with radical surgery, then treated with four cycles of chemotherapy. Two groups of the cases received routine thoracic radiotherapy with a total dose of 45 Gy. One cycle of gemcitabine combined with cisplatin regimen in-cluded gemcitabine 1000 mg/m2 on day 1 and day 8 and cisplatin 25 mg/m2 on day 1, day 2 and day 3 by intravenous infusion, with 21 days as one cycle. The tumor recurrence was evaluated by chest CT and abdominal B-ultrasound. Efficacy and toxicity results were compared by two groups. Results: All patients were followed up for three months to two years. The surgical stage of the experimental group reduced, two-years disease-free survival and postoperative recovery in the experimental group were better than in the control group, the difference was statistical significant. Toxicity and side effect after chemotherapy were mainly bone marrow suppression and gastrointestinal reactions, other complications included thrombocytopenia, leuko-penia, anemia, liver and kidney dysfunction were no significant difference in two groups. Conclusion: Preoperative induction chemotherapy with gemcitabine combined with cisplatin for locally advanced lung cancer can reduce the surgical staging and extend the postoperative disease-free survival.

    International Nuclear Information System (INIS)

    The need for target adjustment due to respiratory motion variation and the value of carina as a motion surrogate is evaluated for locally advanced non-small-cell lung cancer. Using weekly 4D CTs (with audio-visual biofeedback) of 12 patients, respiratory motion variation of primary tumors (PT), lymph nodes (LN) and carina (C) were determined. Mean (SD) 3D respiratory motion ranges of PT, LN and C were 4 (3), 5 (3) and 5 (3) mm. PT and LN (p = 0.003), and LN and C motion range were correlated (p = 0.03). Only 20 %/5 % of all scans had variations >3 mm/5 mm. Large respiratory motion range on the initial scan was associated with larger during-treatment variations for PT (p = 0.03) and LN (p = 0.001). Mean (SD) 3D relative displacements of PT-C, LN-C and PT-LN were each 6 (2) mm. Variations of displacements >3 mm/5 mm were observed in 28 %/6 % of scans for PT-LN, 20 %/9 % for PT-C, and 20 %/8 % for LN-C. Motion reassessment is recommended in patients with large initial motion range. Relative motion-related displacements between PT and LN were larger than PT and LN motion alone. Both PT and C appear to be comparable surrogates for LN respiratory motion

    PurposeTo verify whether microwave ablation (MWA) used as a local control treatment had an improved outcome regarding advanced non-small cell lung cancer (NSCLC) when combined with chemotherapy.MethodsThirty-nine patients with histologically verified advanced NSCLC and at least one measurable site other than the ablative sites were enrolled. Primary tumors underwent MWA followed by platinum-based doublet chemotherapy. Modified response evaluation criteria in solid tumors (mRECIST) and RECIST were used to evaluate therapeutic response. Complications were assessed using the National Cancer Institute Common Toxicity Criteria (version 3.0).ResultsMWA was administered to 39 tumors in 39 patients. The mean and median diameters of the primary tumor were 3.84 cm and 3.30 cm, respectively, with a range of 1.00–9.00 cm. Thirty-three (84.6 %) patients achieved a partial response. No correlation was found between MWA efficacy and clinicopathologic characteristics. For chemotherapy, 11 patients (28.2 %) achieved a partial response, 18 (46.2 %) showed stable disease, and 10 (25.6 %) had progressive disease. The overall objective response rate and disease control rate were 28.2 and 74.4 %, respectively. The median progression-free survival time was 8.7 months (95 % CI 5.5–11.9). The median overall survival time was 21.3 months (95 % CI 17.0–25.4). Complications were observed in 22 (56.4 %) patients, and grade 3 adverse events were observed in 3 (7.9 %) patients.ConclusionsPatients with advanced NSCLC could benefit from MWA in combination with chemotherapy. Complications associated with MWA were common but tolerable.

  11. Phase II study. Concurrent chemotherapy and radiotherapy with nitroglycerin in locally advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Background: Nitroglycerin, a nitric oxide donor agent, reduces the expression of hypoxia-inducible factor-1α (HIF-1α) and could be a normalizer of the tumor microenvironment. Both factors are associated with chemo-radio-resistance. The aim of this study was to determine the safety profile and efficacy of nitroglycerin administration with chemo-radiotherapy in patients with locally advanced non-small cell lung cancer (NSCLC). Methods: This is a phase II trial of locally advanced NSCLC patients treated with cisplatin and vinorelbine plus concurrent nitroglycerin with radiotherapy. A 25-mg NTG patch was administered to the patients for 5 days (1 day before and 4 days after chemotherapy induction and consolidation) and all day during chemo-radiotherapy. VEGF plasmatic level was determined before and after two cycles of chemotherapy. Results: Thirty-five patients were enrolled in this trial. Sixty-three percent of patients achieved an overall response after induction of chemotherapy, and 75% achieved an overall response after chemo-radiotherapy. The median progression-free survival was 13.5 months (95% CI, 8.8–18.2), and the median overall survival was 26.9 months (95% CI, 15.3–38.5). Reduction of VEGF level was associated with better OS. The toxicity profile related to nitroglycerin included headache (20%) and hypotension (2.9%). Conclusions: The addition of nitroglycerin to induction chemotherapy and concurrent chemoradiotherapy in patients with locally advanced NSCLC has an acceptable toxicity profile and supports the possibility to add nitroglycerin to chemotherapy and radiotherapy. A randomized trial is warranted to confirm these findings

    Purpose: Local tumor control and outcome remain poor in patients with advanced non-small-cell lung cancer (NSCLC) treated by external beam radiotherapy. We investigated the therapeutic gain of individualized dose prescription with dose escalation based on normal tissue dose constraints for various hypofractionation schemes delivered with intensity-modulated radiation therapy. Methods and Materials: For 38 Stage III NSCLC patients, the dose level of an existing curative treatment plan with standard fractionation (66 Gy) was rescaled based on dose constraints for the lung, spinal cord, esophagus, brachial plexus, and heart. The effect on tumor total dose (TTD) and biologic tumor effective dose in 2-Gy fractions (TED) corrected for overall treatment time (OTT) was compared for isotoxic and maximally tolerable schemes given in 15, 20, and 33 fractions. Rescaling was accomplished by altering the dose per fraction and/or the number of fractions while keeping the relative dose distribution of the original treatment plan. Results: For 30 of the 38 patients, dose escalation by individualized hypofractionation yielded therapeutic gain. For the maximally tolerable dose scheme in 33 fractions (MTD{sub 33}), individualized dose escalation resulted in a 2.5-21% gain in TTD. In the isotoxic schemes, the number of fractions could be reduced with a marginal increase in TED. For the maximally tolerable dose schemes, the TED could be escalated up to 36.6%, and for all patients beyond the level of the isotoxic and the MTD{sub 33} schemes (range, 3.3-36.6%). Reduction of the OTT contributed to the therapeutic gain of the shortened schemes. For the maximally tolerable schemes, the maximum esophageal dose was the dominant dose-limiting constraint in most patients. Conclusions: This modeling study showed that individualized dose prescription for hypofractionation in NSCLC radiotherapy, based on scaling of existing treatment plans up to normal tissue dose constraints, enables dose

    Full Text Available Epithelial to mesenchymal transition (EMT has an important role in the development of embryo, as well as that in the metastasis of non-small cell lung cancer (NSCLC. Recent researches have demonstrated that both morphological and phenotypic conversions emerge in cells undergoing EMT. As most of relevant studies were on other cancers, it is essential to uncover whether it is the similar mechanisms accounting for EMT in NSCLC. With the progress of the studies, EMT-related basic researches are gradually applied to predicting the prognosis of NSCLC. The aim of this article was to discuss the mechanisms related to EMT emerging in NSCLC.

    Full Text Available Background and objective The epidermal growth factor receptor tyrosine kinase inhibitor (EGFRTKI shows favorable antitumor activity against chemorefractory non-small cell lung cancer (NSCLC. However, patients with advanced NSCLC have limited treatment options available if they are refractory to EGFR-TKI. To study the influence of the retreatment EGFR-TKI after failure of first-line TKI, we carried out this retrospective study. Methods Total 71 patients were analyzed who experienced treatment failure from their initial use of EGFR-TKI. After a period of time, they were retreated with TKI as tumor progression was observed. Results Of the 71 patients who received retreatment TKI, it was observed in 7% in partial response (PR, 36.6% in stable disease (SD, 56.3% in progressive disease (PD. Disease control rate (DCR was 43.7%. Twenty-six (36.6% patients were well controlled by retreatment with TKI monotherapy for not less than 3 months. Five (7.0% patients had partial response. Exon 21 mutation, PFS not less than 6 months during initial treatment TKI, and the interval not less than 3 months between initial treatment, and retreatment with TKI was associated with a good progression free survival based on univariate COX analysis (P=0.034; P=0.013; P=0.046. Conclusion It has been shown the possibility that retreatment with TKI might be useful when (1 Exon 21 has active mutation, (2 initial treatment shows a favorable PFS (≥ 6 months, and (3 there has been a period of time (≥3 months following the termination of the initial TKI treatment.

    Background: [{sup 18}F]fluorodeoxyglucose positron emission tomography (FDG-PET) imaging has been employed as a non-invasive diagnostic tool for malignant tumors. Total lesion glycolysis (TLG) on FDG-PET is calculated by multiplying the mean standardized uptake value (SUVmean) by the tumor volume. Unlike the maximum standardized uptake value (SUVmax), which represents the point of greatest metabolic activity within tumors, TLG has been suggested to reflect global metabolic activity in whole tumors. Methods: We retrospectively examined whether or not FDG-PET measurements, including SUVmean, SUVmax, and TLG, could predict progression-free survival (PFS) or overall survival (OS) in patients with non-small cell lung cancer (NSCLC) receiving chemotherapy. Results: This study involved 81 consecutive patients with NSCLC who received chemotherapy. All of the patients underwent FDG-PET examination before treatment. SUVmean, SUVmax, and TLG on FDG-PET were significantly associated with gender, smoking status, and tumor histology. With adjustment for several other variables, Cox regression analysis showed that TLG was significantly prognostic for both PFS [hazard ratio = 2.34; 95% confidence interval, 1.18–4.64; P = 0.015] and OS (hazard ratio = 2.80; 95% confidence interval, 1.12–6.96; P = 0.003), whereas SUVmean and SUVmax had no significant association with PFS (P = 0.693 and P = 0.322, respectively) or OS (P = 0.587 and P = 0.214, respectively). Conclusions: Our findings suggest that TLG may be more useful than SUVmean and SUVmax for predicting PFS and OS in NSCLC patients receiving chemotherapy. The TLG measurement on FDG-PET imaging could be routinely recommended to advanced NSCLC patients.

    Full Text Available Abstract Background Prophylactic cranial irradiation (PCI has been demonstrated to reduce or delay the incidence of brain metastases (BM in locally advanced non-small cell lung carcinoma (LA-NSCLC patients with various prognostic groups. With this current cohort we planned to evaluate the potential usefulness of prophylactic cranial irradiation (PCI specifically in recursive partitioning analysis (RPA Group 1, which is the most favorable group of LA-NSCLC patients. Methods Between March 2007 and February 2008, 62 patients in RPA group 1 were treated with sequential chemoradiotherapy and PCI for stage IIIB NSCLC. The induction chemotherapy consisted of 3 courses of cisplatin (80 mg/m2 and docetaxel (80 mg/m2; each course was given every 21 days. Thoracic radiotherapy (TRT was given at a dose of 60 Gy using 3-D conformal planning. All patients received a total dose of 30 Gy PCI (2 Gy/fr, 5 days a week, beginning on the first day of the TRT. Then, all patients received 3 further courses of the same chemotherapy protocol. Results Six (9.7% patients developed brain metastases during their clinical course. Only one (2% patient developed brain metastasis as the site of first treatment failure. Median brain metastasis-free survival, overall survival, and progression free survival were 16.6, 16.7, and 13.0 months, respectively. By univariate analysis, rates of BM were significantly higher in patients younger than 60 years of age (p = 0.03. Multivariate analysis showed no significant difference in BM-free survival according to gender, age, histology, and initial T- and N-stage. Conclusion The current finding of almost equal bone metastasis free survival and overall survival in patients with LA-NSCLC in RPA group 1 suggests a longer survival for patients who receive PCI, and thereby have a reduced risk of BM.

    Concurrent radiochemotherapy (RCT) is the treatment of choice for patients with locally advanced non-small-cell lung cancer (NSCLC). Two meta-analyses were inconclusive in an attempt to define the optimal concurrent RCT scheme. Besides efficacy, treatment toxicity will influence the appointed treatment of choice. A systematic review of the literature was performed to record the early and late toxicities, as well as overall survival, of concurrent RCT regimens in patients with NSCLC. The databases of PubMed, Ovid, Medline, and the Cochrane Library were searched for articles on concurrent RCT published between January 1992 and December 2009. Publications of phase II and phase III trials with ≥ 50 patients per treatment arm were selected. Patient characteristics, chemotherapy regimen (mono- or polychemotherapy, high or low dose) and radiotherapy scheme, acute and late toxicity, and overall survival data were compared. Seventeen articles were selected: 12 studies with cisplatin-containing regimens and 5 studies using carboplatin. A total of 13 series with mono- or polychemotherapy schedules--as single dose or double or triple high-dose or daily cisplatin-containing (≤ 30 mg/m(2)/wk) chemotherapy were found. Acute esophagitis ≥ grade 3 was observed in up to 18% of the patients. High-dose cisplatin regimens resulted in more frequent and severe hematologic toxicity, nausea, and vomiting than did other schemes. The toxicity profile was more favorable in low-dose chemotherapy schedules. From phase II and III trials published between 1992 and 2010, it can be concluded that concurrent RCT with monochemotherapy consisting of daily cisplatin results in favorable acute and late toxicity compared with concurrent RCT with single high-dose chemotherapy, doublets, or triplets.

    In cases of locally advanced non-small cell lung cancer (NSCLC), concurrent chemoradiotherapy (CCRT) is the leading therapeutic modality. However, much controversy exists about the chemotherapeutic regimens and radiation methods. Materials and Methods: During concurrent chemoradiotherapy, three or four cycles of gemcitabine (500 mg/m2) and cisplatin (30 mg/m2) were administered every two weeks while 50.4 Gy of irradiation was administered in 28 fractions (once/day, 5 treatment days/week) to the tumor site, mediastinum, and the involved lymph node region. In addition, a booster irradiation dose of 18 Gy in 10 fractions was administered to the primary tumor site unless the disease progressed. Two or three cycles of consolidation chemotherapy were performed with gemcitabine (1,200 mg/m2, 1st and 8th day) and cisplatin (60 mg/m2) every three weeks. Results: A total of 29 patients were evaluable for modality response. Response and treatment toxicities were assessed after concurrent chemoradiotherapy and consolidation chemotherapy, respectively. One patient (4%) achieved a complete response; whereas 20 patients (69%) achieved a partial response after concurrent chemoradiotherapy. Following the consolidation chemotherapy, three patients (10.3%) achieved complete responses and 21 patients (72.4%) achieved partial responses. The median follow-up period was 20 months (range 3-39 months) and the median survival time was 16 months (95% CI; 2.4-39.2 months). The survival rates in one, two, and three years after the completion of treatment were 62.7%, 43.9%, and 20%, respectively. Complications associated to this treatment modality included grade 3 or 4 esophagitis, which occurred in 15 patients (51.7%). In addition, an incidence of 24% for grade 3 and 14% for grade 4 neutropenia. Lastly, grade 2 radiation pneumonitis occurred in 6 patients (22%). Conclusion: The response rate and survival time of concurrent chemoradiotherapy with biweekly gemcitabine (500 mg/m2) and cisplatin

In the GIL-2 group and G-group, we respectively observed: an overall response rate of 16.1% (6.4% complete response) and 5.1% (only partial response); a disease control rate of 41.9% and 41%; a median time to progression of 3.5 (CI 95% = 3.2–3.8) and 4.1 (CI 95% = 2.6–5.7) months; a median overall survival of 20.1 (CI 95% = 5.1–35.1) and 6.9 (CI 95% = 4.9–8.9) months (p = 0.002); and an actuarial one-year survival rate of 54% and 30%. Skin toxicity (p < 0.001; HR = 0.29; CI 95% = 0.16–0.54) and use of IL-2 (p < 0.001; HR = 0.33; CI 95% = 0.18–0.60) were independently associated with improvement of survival. In this consecutive, non-randomized, series of advanced NSCLC patients, the use of IL-2 increased the efficacy of gefitinib.

    Background A retrospective analysis of clinical data were conducted reviewing patients who were given erlotinib at Peking Union Medical College (PUMC) Hospital from May 2005 to December 2009. Relationships between clinical factors, epidermal growth factor receptor (EGFR) mRNA expression, EGFR gene mutations, KRAS gene mutations and clinical outcomes were investigated in Chinese patients with advanced non-small cell lung cancer (NSCLC). Methods Patients with stage ⅢB/Ⅳ NSCLC who had not previously participated in erlotinib related clinical trials were enrolled into this study. All patients were given oral erlotinib 150 mg per day. Tumor samples of some patients were accessed with mutant-enriched polymerase chain reaction assay (EGFR, KRAS gene mutations) and multiplex branched DNA assay (EGFR mRNA expression).Results Seventy-nine patients were enrolled in this study, 23 patients had a partial response (PR), 36 patients had a stable disease (SD), 20 patients had a PD, with an objective response rate of 29.1%, and a disease control rate of 74.7%.Females (P=0.023), non-smokers (P=0.013), patients with a skin rash (P=0.047), and with highly differentiated tumors (P=0.037) were significantly correlated with the objective response rate. Patients with a lower ECOG PS (P=0.002),highly differentiated tumors (P=0.014), non-smokers (P=0.002), and patients with a skin rash (P <0.001) were significantly correlated with the disease control rate. The median progression-free survival was 35 weeks (95% CI: 13-57 weeks) and 1-year survival was 72.3%. Highly-differentiated tumors (P=0.027) and patients with a skin rash (P <0.001)were significantly correlated with PFS. Seventeen patients were tested for EGFR/KRAS gene mutations and EGFR mRNA expression. Progression-free survival (PFS) of patients with EGFR exon 19/21 mutations was 66 weeks, longer than patients with wild type EGFR exon 19/21 (P=0.018). No significant relationships were found between EGFR mRNA expression, EGFR

    Full Text Available Background and objective Advanced non-small cell lung cancer (NSCLC is characterized by poor treatment efficacy and short survival time. Clinical trials have shown that the combination of chemotherapy with thermotherapy exhibits strong efficacy. We performed this meta-analysis to evaluate the clinical efficacy and safety of gemcitabine plus cisplatin (GP and paclitaxel plus cisplatin (TP combined with thermotherapy in the treatment of NSCLC, as well as to provide reference for clinical practice and future research. Methods We searched international (Cochrane Library, PubMed, and EMBASE and Chinese (CBM, CNKI, VIP and Wanfang databases for relevant articles and imported other retrievable sources, such as tracing-related references. We also corresponded with other authors to obtain certain inaccessible information. Data from all relevant randomized controlled trials (RCT were collected to compare GP or TP thermochemotherapy with GP or TP chemotherapy alone. The quality of the included studies was assessed by adequate outcome-based standards and clinical circumstances. The meta-analysis was conducted using RevMan 5.1. Results Fifteen RCTs involving 952 patients were included in this meta-analysis. The results showed that the thermochemotherapy group had higher rates of improvement in quality of life (OR=3.84, 95%CI: 2.61-5.64, survival at 1 year (HR=1.94, 95%CI: 1.21-3.12, and survival at 2 years (HR=2.05, 95%CI: 1.18-3.58 compared with the chemotherapy group, with the differences between them being significant. However, these groups did not differ in other indicators of treatment effectiveness, such as myelosuppression, alimentary canal reactions, hepatic lesions, and diarrhea. Conclusion Compared with chemotherapy alone, thermochemotherapy can improve survival rates and curative effects, ameliorate symptoms, and enhance the quality of life of patients with advanced NSCLC, and it has an acceptable safety profile.

    Full Text Available Context: There are limited effective therapeutic options in the relapsed setting for non-small cell lung cancer (NSCLC or in the first line for platinum-ineligible patients. Aim: To evaluate the safety and efficacy of a metronomic schedule of paclitaxel administered weekly in relapsed refractory NSCLC or upfront in patients not eligible for platinum-based chemotherapy. Settings and Design: Retrospective analysis of a prospectively collected database from the medical oncology department at Tata Memorial Hospital in Mumbai, India. Materials and Methods: Patients with recurrent and treatment-naïve platinum-ineligible advanced NSCLC were treated with weekly paclitaxel at 80 mg/m 2 with palliative intent. Restaging scans were obtained every two months. Chemotherapy was continued until progressive disease, intolerable side effects, or decision of the patient. Statistical Analysis Used: SPSS version 16 was used for analysis. Simple percentages were used for descriptive statistics. Progression-free survival (PFS was calculated from date of start of paclitaxel till the date of progression, change of therapy due to any reason, or death due to any cause. Overall survival (OS was calculated from date of start of paclitaxel to death. The Kaplan Meier method was used for estimation of survival. Results: There were 37 patients over eight months. The median age was 59 years, with a male-to-female ratio of 5:1. Two patients received paclitaxel in the first line, 18 patients in second line, nine in third line, five in fourth line, and three were in fifth line. 73% patients had received prior platinum and 48.6% patients had Eastern Cooperative Oncology Group performance status (ECOG PS >2. The median number of weekly cycles delivered was 14. The response rate was 35% [complete remission (CR: 2.7%, partial remission (PR: 32.4%, stable disease (SD: 32.4%, progressive disease (PD: 27%], the median PFS was four months, and the estimated median OS was seven months

    Purpose: We intended to identify risk factors that affect brain metastases (BM) in patients with locally advanced non-small cell lung cancer (LA-NSCLC) receiving definitive radiation therapy, which may guide the choice of selective prevention strategies. Methods and Materials: The characteristics of 346 patients with stage III NSCLC treated with thoracic radiation therapy from January 2008 to December 2010 in our institution were retrospectively reviewed. BM rates were analyzed by the Kaplan-Meier method. Multivariate Cox regression analysis was performed to determine independent risk factors for BM. Results: The median follow-up time was 48.3 months in surviving patients. A total of 74 patients (21.4%) experienced BM at the time of analysis, and for 40 (11.7%) of them, the brain was the first site of failure. The 1-year and 3-year brain metastasis rates were 15% and 28.1%, respectively. In univariate analysis, female sex, age ≤60 years, non-squamous cell carcinoma, T3-4, N3, >3 areas of lymph node metastasis, high lactate dehydrogenase and serum levels of tumor markers (CEA, NSE, CA125) before treatment were significantly associated with BM (P<.05). In multivariate analysis, age ≤60 years (P=.004, hazard ratio [HR] = 0.491), non-squamous cell carcinoma (P=.000, HR=3.726), NSE >18 ng/mL (P=.008, HR=1.968) and CA125 ≥ 35 U/mL (P=.002, HR=2.129) were independent risk factors for BM. For patients with 0, 1, 2, and 3 to 4 risk factors, the 3-year BM rates were 7.3%, 18.9%, 35.8%, and 70.3%, respectively (P<.001). Conclusions: Age ≤60 years, non-squamous cell carcinoma, serum NSE >18 ng/mL, and CA125 ≥ 35 U/mL were independent risk factors for brain metastasis. The possibilities of selectively using prophylactic cranial irradiation in higher-risk patients with LA-NSCLC should be further explored in the future.

    Radiation dose escalation has been shown to improve local control and survival in patients with non-small cell lung cancer in some studies, but randomized data have not supported this premise, possibly owing to adverse effects. Because of the physical characteristics of the Bragg peak, proton therapy (PT) delivers minimal exit dose distal to the target volume, resulting in better sparing of normal tissues in comparison to photon-based radiation therapy. This is particularly important for lung cancer given the proximity of the lung, heart, esophagus, major airways, large blood vessels, and spinal cord. However, PT is associated with more uncertainty because of the finite range of the proton beam and motion for thoracic cancers. PT is more costly than traditional photon therapy but may reduce side effects and toxicity-related hospitalization, which has its own associated cost. The cost of PT is decreasing over time because of reduced prices for the building, machine, maintenance, and overhead, as well as newer, shorter treatment programs. PT is improving rapidly as more research is performed particularly with the implementation of 4-dimensional computed tomography-based motion management and intensity modulated PT. Given these controversies, there is much debate in the oncology community about which patients with lung cancer benefit significantly from PT. The Particle Therapy Co-operative Group (PTCOG) Thoracic Subcommittee task group intends to address the issues of PT indications, advantages and limitations, cost-effectiveness, technology improvement, clinical trials, and future research directions. This consensus report can be used to guide clinical practice and indications for PT, insurance approval, and clinical or translational research directions. PMID:27084663

    Full Text Available Neha Gupta, Hassan Hatoum, Grace K DyDepartment of Medicine, Roswell Park Cancer Institute, Buffalo, NY, USAAbstract: Lung cancer is the leading cause of cancer mortality worldwide in both men and women. Non-small-cell lung cancer (NSCLC is the most common type of lung cancer, accounting for more than 80% of cases. Paclitaxel has a broad spectrum of activity against various malignancies, including NSCLC. Paclitaxel is poorly soluble in water and thus, until recently, its commercially available preparations contained a non-ionic solvent Cremophor EL®. Cremophor EL® improves the solubility of paclitaxel and allows its intravenous administration. However, certain side-effects associated with paclitaxel, such as hypersensitivity reactions, myelosuppression, and peripheral neuropathy, are known to be worsened by Cremophor®. Nanoparticle albumin-bound paclitaxel ([nab-paclitaxel] ABRAXANE® ABI-007 is a new generation formulation of paclitaxel that obviates the need for Cremophor®, resulting in a safer and faster infusion without requiring the use of premedications to avoid hypersensitivity. Albumin-binding receptor-mediated delivery and lack of sequestering Cremophor® micelles allow higher intratumoral concentration of pharmacologically active paclitaxel. Multiple clinical trials have demonstrated a superior tolerability profile of nab-paclitaxel in comparison to solvent-bound paclitaxel (sb-paclitaxel. A recent Phase III trial compared the effects of weekly nab-paclitaxel in combination with carboplatin versus sb-paclitaxel in combination with carboplatin given every 3 weeks for first line treatment of NSCLC. This trial highlights the weekly nab-paclitaxel combination as an alternate treatment option for NSCLC, with higher response rate in squamous cell NSCLC and longer survival in elderly patients. This review will focus on the properties of nab-paclitaxel and its use in the first line treatment of NSCLC.Keywords: ABI-007, Abraxane, nab

    Purpose: Despite improvements in chemoradiation, local control remains a major clinical problem in locally advanced non-small cell lung cancer. The Hedgehog pathway has been implicated in tumor recurrence by promoting survival of tumorigenic precursors and through effects on tumor-associated stroma. Whether Hedgehog inhibition can affect radiation efficacy in vivo has not been reported. Methods and Materials: We evaluated the effects of a targeted Hedgehog inhibitor (HhAntag) and radiation on clonogenic survival of human non-small cell lung cancer lines in vitro. Using an A549 cell line xenograft model, we examined tumor growth, proliferation, apoptosis, and gene expression changes after concomitant HhAntag and radiation. In a transgenic mouse model of Kras{sup G12D}-induced and Twist1-induced lung adenocarcinoma, we assessed tumor response to radiation and HhAntag by serial micro-computed tomography (CT) scanning. Results: In 4 human lung cancer lines in vitro, HhAntag showed little or no effect on radiosensitivity. By contrast, in both the human tumor xenograft and murine inducible transgenic models, HhAntag enhanced radiation efficacy and delayed tumor growth. By use of the human xenograft model to differentiate tumor and stromal effects, mouse stromal cells, but not human tumor cells, showed significant and consistent downregulation of Hedgehog pathway gene expression. This was associated with increased tumor cell apoptosis. Conclusions: Targeted Hedgehog pathway inhibition can increase in vivo radiation efficacy in lung cancer preclinical models. This effect is associated with pathway suppression in tumor-associated stroma. These data support clinical testing of Hedgehog inhibitors as a component of multimodality therapy for locally advanced non-small cell lung cancer.

    @@ 1 Introduction Recent progress in molecular biology has enabled us to better understand the molecular mechanism underlying pathogenesis of human malignancy including lung cancer. Sequencing of human genome has identified many oncogenes and tumor suppressor genes,giving us a better understanding of the molecular events leading to the formation, progression, metastasis, and the development of drug resistance in human lung cancer. In addition, many signal transduction pathways have been discovered that play important roles in lung cancer. Novel strategy of anti-cancer drug development now involves the identification and development of targeted therapy that interrupts one or more than one pathways or cross-talk among different signal transduction pathways. In addition, efforts are underway that combine the traditional cytotoxic (non-targeted) agents with the biological (targeted) therapy to increase the response rate and survival in patients with lung cancer, especially advanced non-small cell lung cancer (NSCLC).

    Objective: To determine the efficacy and toxicity of hypofractionated thoracic radiotherapy 17 Gray (Gy) in 2 fractions for palliation in advanced non-small-cell lung carcinoma. Study design: A quasi-experimental study. Place and duration of study: Oncology department, Combined Military Hospital, Rawalpindi, from 4th July 2008 to 4th Nov 2009. Material and Methods: Fifty four patients with histologically and/or cytologically confirmed unresectable stages III and IV non small cell lung cancer, with performance status 2 or 3 and expected survival > 2 months were treated with megavoltage radiation therapy 17 Gy in 2 fractions one week apart, with symptoms due to intrathoracic disease (cough, dyspnea and hemoptysis) and toxicity due to radiation therapy (dysphagia secondary to esophagitis) assessed as per common toxicity criteria adverse event version 3.0 on day 0 before treatment and day 30 after start of treatment. Results: Grades of cough, hemoptysis and dyspnea showed significant improvement after treatment (p<0.001). A total of 42.68% patients showed an improvement in grade of cough (23 out of 54 patients), 85.7% of patients showed improvement in grade of hemoptysis (36 out of 42 patients) and 55.65% patients showed improvement in grade of dyspnea (30 out of 54 patients). Twenty two point two percent patients (12 out of 54) showed increase in grade of dysphagia. Although, there was a statistically significant increase in grade of dysphagia after treatment but it was limited to grade 1 and 2 only. Considering that no patient had grade 3 or 4 dysphagia, this toxicity was acceptable. Conclusion: Based on our results hypofractionated thoracic radiotherapy, 17 Gy in 2 fractions, is effective with acceptable toxicity in palliation in advanced non small cell lung cancer and is recommended as it will result in shorter duration of hospital stay and low hospital stay charges.

Gefitinib (Iressa®, the first oral EGFR tyrosine kinase inhibitor, has been shown to be more effective and better tolerated than chemotherapy either in first-line or second-line treatment for patients with advanced NSCLC harboring sensitive EGFR mutations. Conversely, among patients with wild-type EGFR, gefitinib is inferior to standard chemotherapy in both the first-line and second-line settings. Further, gefitinib is effective in patients with brain metastases because of its low molecular weight and excellent penetration of the blood–brain barrier. In this review, we summarize the current data from clinical trials with gefitinib and appraise its role in the management of locally advanced or metastatic NSCLC.Keywords: gefitinib, non-small cell lung cancer, epidermal growth factor receptor, tyrosine kinase inhibitor

    Full Text Available In recent years, the five-year survival rate of patients with advanced stage non-small cell lung cancer (NSCLC remains low despite recent advances in surgery, irradiation, chemotherapy, and targeted therapy. Immunotherapy which utilizes the immune system to control and eradicate cancer is a viable treatment approach for malignancy. Immunotherapy in patients with lung cancer has made breakthrough progress recently. Novel immunotherapeutic agents, such as antigen-specific tumour vaccines, checkpoint inhibitors, etc, have all been evaluated in lung cancer, and some have shown prolonged survival time in phase II trials and III trails. The immune-related response criteria for the evaluation of antitumor responses with immunotherapeutic agents have been made. Now, immunotherapy will likely be a fundamentally new concept for the treatment of NSCLC.

  5. Chemotherapy with cisplatin and vinorelbine for elderly patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC)

    International Nuclear Information System (INIS)

    Although modest improvements in the survival of patients with non-small cell lung cancer (NSCLC) can be achieved with cisplatin-based chemotherapy (CT), its value is disputed in the geriatric setting. In this study, we evaluate the feasibility of vinorelbine/cisplatin CT for elderly NSCLC patients. In this pilot phase I/II trial, all patients received CT with vinorelbine 25 mg/m2, on day 1 and 8, and cisplatin on day 1, in 28 days-cycles. After stratification for age (up to 75 years), younger patients were sequentially allocated to moderate cisplatin doses (80 mg/m2 or 90 mg/m2), and older patients were allocated to lower cisplatin doses (60 mg/m2 or 70 mg/m2). We recruited patients aged over 70 years with newly diagnosed NSCLC, clinical stage III or IV, Karnofsky performance status ≥ 70%, normal serum creatinine, peripheral neuropathy ≤ grade 1, and no prior cancer therapy. Analysis was by intention to treat. Main toxicities (grade 3–4) was as follows: neutropenia, 20%; anemia, 11%; and thrombocytopenia, 2%; alopecia, 55%; fatigue, 11%; and peripheral neurotoxicity, 2%. No grade 3–4 emesis or renal toxicity occurred. Global median time to progression (TTP) and overall survival (OS) were 27.0 (95% CI: 10.1 to 43.7) weeks and 30.1 (95% CI: 24.4 to 35.8) weeks; 1- and 2-year survival rates were 36.3% and 13.2%, respectively. Overall response rate was 50.0% (95% CI: 35.4% to 64.5%), with 1 complete response; no difference on response rate was noticed according to cisplatin dose. Median overall survival was 30.1 weeks, with 1- and 2-year survival rates of 36.3% and 13.2%, respectively. Age does not preclude assessment on the role of cisplatin-vinorelbine CT for elderly NSCLC patients with good performance status and adequate bodily functions

    Full Text Available PURPOSE: This study evaluated occurrence and potential clinical significance of intratumoral EGFR mutational heterogeneity in Chinese patients with non-small cell lung cancer (NSCLC. MATERIALS AND METHODS: Eighty-five stage IIIa-IV NSCLC patients who had undergone palliative surgical resection were included in this study. Of these, 45 patients carried EGFR mutations (group-M and 40 patients were wild-type (group-W. Each tumor sample was microdissected to yield 28-34 tumor foci and Intratumoral EGFR mutation were determined using Denaturing High Performance Liquid Chromatography (DHPLC and Amplification Refractory Mutation System (ARMS. EGFR copy numbers were measured using fluorescence in situ hybridization (FISH. RESULTS: Microdissection yielded 1,431 tumor foci from EGFR mutant patients (group-M and 1,238 foci from wild-type patients (group-W. The EGFR mutant frequencies in group-M were 80.6% (1,154/1,431 and 87.1% (1,247/1,431 using DHPLC and ARMS, respectively. A combination of EGFR-mutated and wild-type cells was detected in 32.9% (28/85 of samples by DHPLC and 28.2% (24/85 by ARMS, supporting the occurrence of intratumoral heterogeneity. Thirty-one patients (36.5% were identified as EGFR FISH-positive. Patients harboring intratumoral mutational heterogeneity possessed lower EGFR copy numbers than those tumors contained mutant cells alone (16.7% vs. 71.0%, P<0.05. Among 26 patients who had received EGFR-TKIs, the mean EGFR mutation content was higher in patients showing partial response (86.1% or stable disease (48.7% compared with patients experiencing progressive disease (6.0% (P = 0.001. There also showed relationship between progression-free survival (PFS and different content of EGFR mutation groups (pure wild type EGFR, EGFR mutation with heterogeneity and pure mutated EGFR (P = 0.001. CONCLUSION: Approximately 30% of patients presented intratumoral EGFR mutational heterogeneity, accompanying with relatively low EGFR copy

  7. Risk factors for radiation induced lung toxicity in locally advanced non-small cell lung cancer treated with three-dimensional radiotherapy

    International Nuclear Information System (INIS)

    Objective: To investigate the patient and treatment related predictors for the development of radiation induced lung toxicity (RILT) in patients with locally advanced non-small cell lung cancer (NSCLC) receiving definitive three-dimensional radiotherapy. Methods: Data were retrospectively collected from inoperable or unresectable 253 patients with stage III NSCLC treated with definitive three-dimensional radiotherapy between January 2001 and April 2007. National cancer institute common toxicity criteria version 3.0 was employed to evaluate the classification of RILT and grade ≥2 toxicity served as the endpoint. The correlation between RILT and aforementioned factors was analyzed. Results: The grade ≥ 2 RILT was 26.5%. Univariate analysis showed age, FEV1%, DLCO%, contralateral lung (CL) V5 -V15, ipsilateral lung (IL) V5 -V40, total lung (TL) V5 -V50, IL and TL mean lung dose (MLD) were significantly correlated with the development of RILT (χ2 =4.46 - 23.99, P = 0.000 - 0.035). Multivariate analysis showed TL MLD >17.5 Gy and FEV1% ≥72% were significantly correlated with the development of RILT (χ2 = 17.49, 9.30, P = 0.000, 0.002). Patients were stratified into four groups according to MLD and FEV1%, corresponding to the RILT incidence of 9.3%, 24.7%, 38.5% and 63.6%, respectively (χ2 =25.27, P = 0.000). Conclusions: TL MLD and baseline FEV1% are significant factors correlated with the development of RILT in NSCLC patients treated with three-dimensional radiation therapy. The combination of TL MLD and FEV1% may help classify NSCLC patients per risk of RILT and subsequently direct risk-adaptive radiation therapy. Poor baseline pulmonary function does not increase the risk of RILT and may even be associated with lower RILT probability, which has yet to be validated in larger patient cohorts. (authors)

    Full Text Available An increasing number of patients with advanced non-small cell lung cancer (NSCLC have been treated with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs. However, significant differences in response to EGFR-TKIs have been shown among advanced NSCLC patients. Recently, selection of patients was mainly based on EGFR gene mutation detection. Nevertheless, mutation detection is often limited by tumour tissues derivation, technique complexity, high cost, and so on. It is urgent to seek other biological markers to predict efficacy of EGFR-TKIs. Many studies have founded that the EGFR gene polymorphisms are also associated with clinical outcome and prognosis in treatment of advanced NSCLC with EGFR-TKIs. Here, we presented a review discussing the correlation between EGFR gene polymorphisms and the efficacy of EGFR-TKIs in advanced NSCLC.

    Past studies have demonstrated that epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors can significantly improve clinical outcomes in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) and sensitive EGFR gene mutations. Gefitinib (Iressa(®)), the first oral EGFR tyrosine kinase inhibitor, has been shown to be more effective and better tolerated than chemotherapy either in first-line or second-line treatment for patients with advanced NSCLC harboring sensitive EGFR mutations. Conversely, among patients with wild-type EGFR, gefitinib is inferior to standard chemotherapy in both the first-line and second-line settings. Further, gefitinib is effective in patients with brain metastases because of its low molecular weight and excellent penetration of the blood-brain barrier. In this review, we summarize the current data from clinical trials with gefitinib and appraise its role in the management of locally advanced or metastatic NSCLC.

  11. SU-E-T-572: Normal Lung Tissue Sparing in Radiation Therapy for Locally Advanced Non-Small Cell Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: To compare normal lung-sparing capabilities of three advanced radiation therapy techniques for locally advanced non-small cell lung cancer (LA-NSCLC). Methods: Four-dimensional computed tomography (4DCT) was performed in 10 patients with stage IIIb LA-NSCLC. The internal target volume (ITV); planning target volume (PTV); and organs at risks (OARs) such as spinal cord, total normal lung, heart, and esophagus were delineated for each CT data set. Intensity-modulated radiation therapy (IMRT), Tomohelical-IMRT (TH-IMRT), and TomoDirect-IMRT (TD-IMRT) plans were generated (total prescribed dose, 66 Gy in 33 fractions to the PTV) for each patient. To reduce the normal lung dose, complete and directional block function was applied outside the normal lung far from the target for both TH-IMRT and TD-IMRT, while pseudo- OAR was set in the same region for IMRT. Dosimetric characteristics of the three plans were compared in terms of target coverage, the sparing capability for the OAR, and the normal tissue complication probability (NTCP). Beam delivery efficiency was also compared. Results: TH-IMRT and TD-IMRT provided better target coverage than IMRT plans. Lung volume receiving ≥–30 Gy, mean dose, and NTCP were significant with TH-IMRT than with IMRT (p=0.006), and volume receiving ≥20–30 Gy was lower in TD-IMRT than in IMRT (p<0.05). Compared with IMRT, TH-IMRT had better sparing effect on the spinal cord (Dmax, NTCP) and heart (V45) (p<0.05). NTCP for the spinal cord, V45 and V60 for the heart, and Dmax for the esophagus were significantly lower in TD-IMRT than in IMRT. The monitor units per fraction were clearly smaller for IMRT than for TH-IMRT and TD-IMRT (p=0.006). Conclusion: In LA-NSCLC, TH-IMRT gave superior PTV coverage and OAR sparing compared to IMRT. TH-IMRT provided better control of the lung volume receiving ≥5–30 Gy. The delivery time and monitor units were lower in TD-IMRT than in TH-IMRT

    International Nuclear Information System (INIS)

    Objective: To assess the short-term efficacy of bronchial artery infusion (BAI) of Gemcitabine (GEM) plus Cisplatin (DDP) combined with systemic chemotherapy of GEM for advanced non-small cell lung cancer (NSCLC). Methods: A total of 60 patients with pathologically proved primary NSCLC were randomly selected. BAI with GEM (1000 mg/m2) and DDP (DDP 50 mg/m2) was performed on the first day, and systemic chemotherapy of GEM (1000 mg/m2) was carried out on the eighth day. The clinical results were analyzed. Results: Of the 60 patients, CR, PR, SD and PD were obtained in 3, 35, 17 and 5, respectively, with an overall effective rate of 63%. Twenty-two patients had adenocarcinoma and the effective rate of them was 45%. Thirty-eight patients had squamous cell carcinoma and their effective rate was 74%. The difference in the effective rate between the above two pathologic types was significant (P<0.05). Central type lung cancer was seen in 37 cases, their effective rate was 73%. The peripheral type lung cancer was seen in the remaining 23 patients and the effective rate was 48%. The difference in the effective rate was statistically significant between the central type and the peripheral type (P<0.05). Conclusion: The combination of bronchial artery infusion with systemic chemotherapy by using GP plan is an effective, feasible approach in the treatment of advanced non-small cell lung cancer. The short-term efficacy of the treatment bears a close relationship to the anatomical location and pathological type of the cancer. (authors)

  15. Interstitial lung abnormalities in treatment-naïve advanced non-small-cell lung cancer patients are associated with shorter survival

    International Nuclear Information System (INIS)

    Highlights: • Interstitial lung abnormalities were present in 14% of stage IV NSCLC patients. • ILA was more common in older patients with heavier smoking history. • ILA was associated with shorter survival after adjusting for smoking and therapy. • ILA could be an additional independent marker for survival in advanced NSCLC. - Abstract: Objective: Interstitial lung diseases are associated with increased risk of lung cancer. The prevalence of ILA at diagnosis of advanced non-small-cell lung cancer (NSCLC) and its impact on overall survival (OS) remain to be investigated. Materials and method: The study included 120 treatment-naïve stage IV NSCLC patients (53 males, 67 females). ILA was scored on CT prior to any systemic therapy using a 4-point scale [0 = no evidence of ILA, 1 = equivocal for ILA, 2 = suspicious for ILA, 3 = ILA] by a sequential reading method previously reported. ILA scores of 2 or 3 indicated the presence of ILA. Results: ILA was present in 17 patients (14%) with advanced NSCLC prior to any treatment (score3: n = 2, score2: n = 15). These 17 patients were significantly older (median age: 69 vs. 63, p = 0.04) and had a heavier smoking history (median: 40 vs. 15.5 pack-year, p = 0.003) than those with ILA score 0 or 1. Higher ILA scores were associated with shorter OS (p = 0.001). Median OS of the 17 patients with ILA was 7.2 months [95%CI: 2.9–9.4] compared to 14.8 months [95%CI: 11.1–18.4] in patients with ILA score 0 or 1 (p = 0.002). In a multivariate model, the presence of ILA remained significant for increased risk for death (HR = 2.09, p = 0.028) after adjusting for first-line systemic therapy (chemotherapy, p < 0.001; TKI, p < 0.001; each compared to no therapy) and pack years of smoking (p = 0.40). Conclusion: Radiographic ILA was present in 14% of treatment-naïve advanced NSCLC patients. Higher ILA scores were associated with shorter OS, indicating that ILA could be a marker of shorter survival in advanced NSCLC

  17. The relationship between glasgow prognostic score and serum tumor markers in patients with advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Glasgow Prognostic Score (GPS) has been reported as a powerful prognostic tool for patients with advanced non–small cell lung cancer (NSCLC). The aim of this study was to assess the relationship between GPS and prognosis related tumor markers in patients with advanced NSCLC. We included 138 advanced NSCLC patients and twenty healthy controls in the study. GPS was calculated by combined serum C-reactive protein (CRP) and albumin. Three serum tumor markers, which included cytokeratin 19 fragment antigen 21-1 (CYFRA21–1), carcinoembryonic antigen (CEA) and tissue polypeptide specific antigen (TPS), were detected by enzyme-linked immunosorbent assay (ELISA). GPS and tumor markers were all assessed before chemotherapy. All patients received at least 2 courses of cisplatin-based chemotherapy. After that, 2 to 5 years follow-up was conducted. Median levels of CYFRA21–1 were 1.5 ng/ml (0.1–3.1 ng/ml) in healthy controls, and 4.6 ng/ml (0.7–35.2 ng/ml) in GPS 0 advanced NSCLC, 11.2 ng/ml (0.4–89.2) ng/ml in GPS 1 advanced NSCLC, and 15.7 ng/ml (2.9–134.6 ng/ml) in GPS 2 advanced NSCLC, respectively. Median levels of CYFRA21-1 were higher in NSCLC patients than in healthy controls, and CYFRA21-1 increased gradually according to GPS category in NSCLC patients (P < 0.05). Similar results were found for median levels of CEA and TPS in healthy controls and NSCLC patients (P < 0.05). In NSCLC patients, positive correlations were found between CYFRA21-1 and GPS, CEA and GPS, TPS and GPS. The Spearman’s rank correlation coefficient were 0.67 (P < 0.05), 0.61 (P < 0.05) and 0.55 (P < 0.05), respectively. Survival analyses showed GPS was an independent prognostic factor for advanced NSCLC. CYFRA21-1(>3.3 ng/ml) and TPS (>80 U/l) were related with the prognosis of advanced NSCLC by univariate analyses, but multivariate analyses showed CYFRA21-1, TPS and CEA were not the independent prognostic factors for advanced NSCLC. Our results showed GPS were positive correlated

    DNA repair capacity(DRC)is correlated with sensi tivity of cancer cells toward platinum-based chemotherapy.We hypothesize that genetic polymorphisms in DNA repair gene XPA(xeroderma pigmentosum group A)and XPG(xeroderma pigmentosum group G)(ERCC5,excision repair cross-complementation group 5),which result in inter-individual differences in DNA repair efficiency,may predict clinical response to platinum agents in advanced non-small cell lung cancer (NSCLC)patients.In this study,we find that the A→G change of XPA A23G polymorphism significantly increased response to platinum-based chemotherapy.Polymorphism in XPG His46His was associated with a decreased treatment response,but was not statistically significant.

    Full Text Available OBJECTIVE: Non-small cell lung carcinoma (NSCLC is the most common type of lung cancer. Most patients are diagnosed at an advanced stage, palliative chemotherapy therefore being the only treatment option. This study was aimed at evaluating the health-related quality of life (HRQoL of advanced-stage NSCLC patients receiving palliative chemotherapy with carboplatin and paclitaxel. METHODS: This was a multiple case study of advanced-stage NSCLC outpatients receiving chemotherapy at a public hospital in Rio de Janeiro, Brazil. The European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire was used in conjunction with its supplemental lung cancer-specific module in order to assess HRQoL. RESULTS: Physical and cognitive functioning scale scores differed significantly among chemotherapy cycles, indicating improved and worsened HRQoL, respectively. The differences regarding the scores for pain, loss of appetite, chest pain, and arm/shoulder pain indicated improved HRQoL. CONCLUSIONS: Chemotherapy was found to improve certain aspects of HRQoL in patients with advanced-stage NSCLC.

    Full Text Available Organizing pneumonia (formerly known as bronchiolitis obliterans organizing pneumonia, BOOP is an inflammatory process of the bronchioles that can lead to the destruction of small airways and surrounding lung tissue. Although the majority of cases are idiopathic, certain chemicals and drugs can induce OP. Here, we report a 54-year-old male patient with advanced non-small cell lung cancer (NSCLC who developed therapy-associated OP. He had undergone several other chemotherapies before being switched to docetaxel as monotherapy (75 mg/m2. Treatment was initially well tolerated, but after the second cycle the patient developed increasing shortness of breath. Computed tomography (CT for staging after the second cycle showed bilateral predominantly interstitial infiltration highly suggestive of acute lung fibrosis. Bronchoscopy revealed signs of chronic bronchitis and watery discharge from both lungs. Bronchoalveolar lavage and transbronchial needle biopsy was performed. Based on histopathologic examination, diagnosis of OP was made. After cessation of docetaxel and initial high dose steroids, the infiltration ameliorated rapidly. This is the second case in the literature that associates docetaxel with rapid onset of bronchiolitis obliterans. Therefore, patients with lung cancer receiving docetaxel who develop respiratory symptoms should be suspected to develop OP.

    Full Text Available Background/Aim. As therapy for locally advanced nonsmall cell lung carcinoma (NSCLC improves, brain metastases (BM still remain a great problem. The aim of the study was to analyze risk factors for BM in patients with locally advanced NSCLC after chemoradiation therapy. Methods. Records for 150 patients with non-resectable stage IIIA/IIIB NSCLC treated with combined chemoradiation therapy were analyzed. All of them had negative brain metastases imaging result before the treatment. Incidence of BM was examined in relation to age, sex, histological type, stage, performance status scale of wellbeing of cancer patients, weight loss, chemotherapy regimen and chemotherapy timing. Results. One- and 2-year incidence rates of BM were 19 and 31%, respectively. Among pretreatment parameters, stage IIIB was associated with a higher risk of BM (p < 0.004 vs stage IIIA. Histologically, the patients with nonsquamous tumors had an exceptionally high 2-year BM risk rate of 32% (p < 0.02. Examining treatment-related parameters, 1-year and 2-year actuarial risk of BM were 27 and 39%, respectively, in the patients receiving chemotherapy before radiotherapy and 15 and 20%, respectively, when radiotherapy was not delayed (p < 0.03. On multivariate analysis, timing of chemotherapy (p < 0.05 and stage IIIA vs IIIB (p < 0.01 remained statistically significant. Conclusion. Patients with IIIB stage, nonsquamous NSCLC, particularly those receiving sequential chemotherapy, had significantly high BM rates.

    Purpose: To compare helical tomotherapy (HT) and conventional intensity-modulated radiotherapy (IMRT) using a variety of dosimetric and radiobiologic indexes in patients with locally advanced non-small cell lung cancer (LA-NSCLC). Patients and methods: A total of 20 patients with LA-NSCLC were enrolled. IMRT plans with 4-6 coplanar beams and HT plans were generated for each patient. Dose distributions and dosimetric indexes for the tumors and critical structures were computed for both plans and compared. Results: Both modalities created highly conformal plans. They did not differ in the volumes of lung exposed to > 20 Gy of radiation. The average mean lung dose, volume receiving {>=} 30 Gy, and volume receiving {>=} 10 Gy in HT planning were 18.3 Gy, 18.5%, and 57.1%, respectively, compared to 19.4 Gy, 25.4%, and 48.9%, respectively, with IMRT (p = 0.004, p < 0.001, and p < 0.001). The differences between HT and IMRT in lung volume receiving {>=} 10-20 Gy increased significantly as the planning target volume (PTV) increased. For 6 patients who had PTV greater than 700 cm{sup 3}, IMRT was superior to HT for 5 patients in terms of lung volume receiving {>=} 5-20 Gy. The integral dose to the entire thorax in HT plans was significantly higher than in IMRT plans. Conclusion: HT gave significantly better control of mean lung dose and volume receiving {>=} 30-40 Gy, whereas IMRT provided better control of the lung volume receiving {>=} 5-15 Gy and the integral dose to entire thorax. In most patients with PTV greater than 700 cm{sup 3}, IMRT was superior to HT in terms of lung volume receiving {>=} 5-20 Gy. It is therefore advised that caution should be exercised when planning LA-NSCLC using HT. (orig.)

    To assess whether tumour heterogeneity, quantified by texture analysis (TA) on contrast-enhanced computed tomography (CECT), can predict response to chemotherapy in advanced non-small cell lung cancer (NSCLC). Fifty-three CECT studies of patients with advanced NSCLC who had undergone first-line chemotherapy were retrospectively reviewed. Response to chemotherapy was evaluated according to RECIST1.1. Tumour uniformity was assessed by a TA method based on Laplacian of Gaussian filtering. The resulting parameters were correlated with treatment response and overall survival by multivariate analysis. Thirty-one out of 53 patients were non-responders and 22 were responders. Average overall survival was 13 months (4-35), minimum follow-up was 12 months. In the adenocarcinoma group (n = 31), the product of tumour uniformity and grey level (GL*U) was the unique independent variable correlating with treatment response. Dividing the GL*U (range 8.5-46.6) into tertiles, lesions belonging to the second and the third tertiles had an 8.3-fold higher probability of treatment response compared with those in the first tertile. No association between texture features and response to treatment was observed in the non-adenocarcinoma group (n = 22). GL*U did not correlate with overall survival. TA on CECT images in advanced lung adenocarcinoma provides an independent predictive indicator of response to first-line chemotherapy. (orig.)

  8. Quality of life assessment in advanced non-small-cell lung cancer patients undergoing an accelerated radiotherapy regimen: report of ECOG study 4593

    International Nuclear Information System (INIS)

    Purpose: To prospectively evaluate the quality of life (QOL) before, at completion, and after therapy for patients receiving an accelerated fractionation schedule of radiotherapy for advanced, unresectable non-small-cell lung cancer in a Phase II multi-institutional trial. Methods and Materials: The Functional Assessment of Cancer Therapy-Lung (FACT-L) patient questionnaire was used to score the QOL in patients enrolled in the Eastern Cooperative Oncology Group Phase II trial (ECOG 4593) of hyperfractionated accelerated radiotherapy in non-small-cell lung cancer. Radiotherapy (total dose 57.6 Gy in 36 fractions) was delivered during 15 days, with three radiation fractions given each treatment day. The protocol was activated in 1993, and 30 patients had accrued by November 1995. The FACT-L questionnaire was administered at study entry (baseline), on the last day of radiotherapy (assessment 2), and 4 weeks after therapy (assessment 3). The FACT-L includes scores for physical, functional, emotional, and social well-being (33 items), and a subscale of lung cancer symptoms (10 additional items). The summation of the physical, functional, and lung cancer symptom subscales (21 items) constitutes the Trial Outcome Index (TOI), considered the most clinically relevant outcome measure in lung cancer treatment trials. Results: The FACT-L completion rates at the designated study time points were as follows: baseline, 30 of 30 (100%); assessment 2, 29 (97%) of 30; and assessment 3, 24 (80%) of 30. At treatment completion, statistically significant declines in QOL scores were noted, compared with baseline for physical and functional well-being. Emotional well-being scores improved at both assessment 2 and assessment 3. The physical and functional scores returned approximately to baseline values at assessment 3. The change in TOI score was evaluated as a function of the clinical response to treatment, toxicity grade, and survival; no clear association was noted. A trend for the

    Background Platinum-based chemotherapeutics are the most common regimens for advanced non-small-cell lung cancer (NSCLC) patients, and genetic factors are thought to represent important determinants of drug efficacy. We prospectively assessed the status of the XPC Ala499Val and Lys939GIn gene polymorphisms and investigated whether these SNPs can predict the response to cisplatin/carboplatin-based regimens in advanced NSCLC patients in a Chinese population.Methods The treatment outcomes of 96 advanced NSCLC patients who were treated with platinum-based chemotherapy were evaluated. The polymorphic status of xeroderma pigmentosum group C (XPC) gene was genotyped by the 3-D polyacrylamide gel-based DNA microarray method.Results The distributions of XPC Lys939GIn genotypes differed significantly between the response group (complete +partial responses) and the non-response group (stable + progressive disease; P=0.022). The heterozygous A/C genotype carriers had a poorer response rate than the wild A/A genotype carriers in stage Ⅲ (OR, 0.074; 95% CI,0.008-0.704; P=0.023). The XPC Ala499Val polymorphisms were not associated with response to platinum-based chemotherapy.Conclusion Polymorphisms of the XPC gene, Lys939GIn, may be a predictive marker of treatment response for advanced NSCLC patients in stage Ⅲ.

    Drugs that specifical y target the tyrosine kinase domain of epidermal growth factor receptor (EGFR), such as erlotinib or gefitinib, have exhibited striking ef icacy in non-smal cel lung cancer (NSCLC) patients har-boring activating EGFR mutations. However, acquired resistance inevitably develops and remains a serious barrier for the successful management of patients with this disease. Multiple mechanisms are reportedly involved in the process of acquired resistance, which provide new insights into the management of EGFR-tyrosine kinase inhibitor (EGFR-TKI) resistance. Here, we provide an overview of the emerging treatment approaches for patients with EGFR-TKI resistance.

    Full Text Available Background and objective Since the poor outcome for advanced lung cancer with first-line chemotherapy, more efforts should be paid for treatment of advanced recurrent or metastasis non-small cell lung cancer (NSCLC patients. Pemetrexed, as a multi-target antifolate chemotherapeutic drug, was approved for the second-line treatment of advanced NSCLC. The aim of this study is to evaluate the efficacy and side effects of pemetrexed combined with cisplatin/carboplatin in the treatment of advanced recurrent or metastasis NSCLC. Methods Sixty-three advanced recurrent or metastasis NSCLC patients confirmed with pathology or cytology were enrolled in this study. Among them, 40 cases were male and 23 were female, with 62 years of median age. The combination regimen was patients received pemetrexed 500 mg/m2 on day 1 and cisplatin 30 mg/m2 on day 1, day 2 and day 3 or carboplatin 300 mg/m2 on day 1 by intravenous infusion, with 21 days as one cycle. All patients who received 2 or more cycles could be evaluated. Results Only 1 case got complete response, with 5 cases partial response, 36 stable and 21 cases progressive. The overal control rate was 66.7% (42/63. The median survival time was 9.0 months, while the median progression-free survival was 5.0 months (3.0 months in squamous cell carcinoma; 5.5 months in adenocarcinoma. There was a significant difference between squamous cell carcinoma and adenocarcinoma (P=0.017. The common adverse effects were leucopenia, anemia and gastrointestinal response. Conclusion Pemetrexed combined with cisplatin/carboplatin is effective and feasible for advanced recurrent or metastasis NSCLC.

    We analyzed the association between polymorphisms in three glutathione S-transferase genes (GSTP1, GSTM1, and GSTT1) and the treatment outcome for advanced non-small cell lung cancer (NSCLC). We recruited 284 NSCLC patients at advanced stage from Department of Radiotherapy in Peace Hospital Attached to Changzhi Medical College between May 2009 and May 2011, who had received cisplatin-based chemotherapy. The GSTP1, GSTM1, and GSTT1 genotyping for was determined using DNA pyrosequencing on an ABI Prism 3100 DNA analyzer. In the Cox proportional hazards model, the IIe/Val and Val/Val genotypes of GSTP1 were associated with lower risk of disease progression compared with the IIe/IIe genotype, and the HRs (95%CIs) were 0.37 (0.18-0.74) and 0.15 (0.06-0.35), respectively. The IIe/Val and Val/Val genotypes significantly decreased risk of death from all causes in patients with NSCLC, and the HRs (95%CIs) were 0.52 (0.29-0.92) and 0.37 (0.17- 0.79), respectively No significant association was observed between GSTM1 and GSTT1 polymorphisms and progression-free survival and overall survival in the NSCLC patients. In summary, we suggest that GSTP1 polymorphisms might influence the treatment outcome of advanced NSCLC patients, and our results could help improve individualized therapy. PMID:27525853

    Non-small-cell lung cancer (NSCLC) is an increasing global challenge, especially in low-income countries. Most guidelines for the management of advanced-stage NSCLC have limited effect in countries with resource constraints. Following a systematic literature search, we present an overview of the management of advanced-stage NSCLC in the first-line setting, discuss resources required for systemic therapy, and provide treatment recommendations stratified to four resources levels. Treatment guidelines appropriate for different resource levels offer a realistic approach to management of advanced-stage NSCLC, by recognising the limitations of a particular health-care system. Although there are many barriers to cancer control in low-resource countries, these can be overcome by using measures that are culturally appropriate, economically feasible, and evidence-based. Initiatives include strategic planning, tobacco control, training of health-care workers, access to therapeutic agents, acquisition of information, public education, and alliances with established institutions and international organisations.

      We retrospectively evaluated clinical data before therapy to determine the risk factors for severe neutropenia in advanced non-small-cell lung cancer (NSCLC) patients treated with third-generation agents. We analyzed 100 patients who received such agents (paclitaxel, docetaxel, gemcitabine, irinotecan, or vinorelbine) for advanced NSCLC. The endpoint of the survey was the occurrence of severe neutropenia (grade 4). Risk factors significantly related to severe neutropenia were identified using logistic regression analysis. Of the 100 patients studied, the median age was 62.0 (32-81 years), and 77 (77.0%) were male. CEA 6.6 (0-2220) ng/dL and cytokeratin 19 fragment 21-1 (CYFRA) 4.8 (0.2-173.8) ng/dL before chemotherapy were higher than normal range. Severe neutropenia occurred in 36.0%, the incidence being highest in the first cycle (61.1%). In the univariate analysis, variables associated with severe neutropenia were sex, chest pain, absolute neutrophil count (ANC), Cr, CRP, and CYFRA. In the multivariate analysis, low CYFRA level was identified as a significant risk factor that contributed independently to chemotherapy-induced severe neutropenia (pCYFRA level is the most important risk factor for severe neutropenia in advanced NSCLC patients after the first course of chemotherapy with third-generation agents.

  20. Comparison of dose distribution between simplified IMRT and different curative radiotherapy plans for locally advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Objective: To evaluate the dose distribution of target volume and normal tissues with different treatment planning such as three dimensional conformal radiotherapy (3DCRT), Simplified intensity-modulated radiotherapy (sIMRT), and intensity-modulated radiotherapy (IMRT) for patients with locally advanced non-small cell lung carcinoma (NSCLC). Methods: Fourteen patients with stage III NSCLC who underwent concurrent radio chemotherapy were enrolled in this study. Five-field 3D-CRT, sIMRT and 5-field or 7-field IMRT plans were performed for each patient. The dose distributions of target volume and normal tissues, conformal index (CI), and heterogeneous index (HI) were analyzed using the dose-volume histogram for these techniques. The prescription dose was 60 Gy in 30 fractions. The total monitor units (MU) were also analyzed to compare the execution time indirectly. Results: The CI for planning target volume (PTV) was superior with IMRT, sIMRT to 3DCRT. Conversely, the HI for PTV was 3DCRT > sIMRT > IMRT. sIMRT and IMRT can protect the organs at risk better than 3DCRT. The mean of total MU for 3DCRT5f, sIMRT, IMRT5f and IMRT7f was 476±23, 523±29, 764±51 and 793±44, respectively. Conclusions: Comparing with 3DCRT and IMRT, sIMRT was optimal for clinical practice. sIMRT and IMRT radiotherapy techniques can protect the lung and spinal cord well. (authors)

    Purpose: To evaluate implanted markers as a surrogate for tumor-based setup during image-guided lung cancer radiotherapy with audiovisual biofeedback. Methods and Materials: Seven patients with locally advanced non-small-cell lung cancer were implanted bronchoscopically with gold coils. Markers, tumor, and a reference bony structure (vertebra) were contoured for all 10 phases of the four-dimensional respiration-correlated fan-beam computed tomography and weekly four-dimensional cone-beam computed tomography. Results: The systematic/random interfractional marker-to-tumor centroid displacements were 2/3, 2/2, and 3/3 mm in the x (lateral), y (anterior-posterior), and z (superior-inferior) directions, respectively. The systematic/random interfractional marker-to-bone displacements were 2/3, 2/3, and 2/3 mm in the x, y, and z directions, respectively. The systematic/random tumor-to-bone displacements were 2/3, 2/4, and 4/4 mm in the x, y, and z directions, respectively. All displacements changed significantly over time (p < 0.0001). Conclusions: Although marker-based image guidance may decrease the risk for geometric miss compared with bony anatomy-based positioning, the observed displacements between markers and tumor centroids indicate the need for repeated soft tissue imaging, particularly in situations with large tumor volume change and large initial marker-to-tumor centroid distance.

While the regimen is associated with several grade ≥3 toxicities, hyponatremia is not a commonly reported adverse effect. Here we report an unusually high incidence of grade ≥3 hyponatremia in Indian patients receiving pemetrexed-platinum doublet, and the pharmacological basis for this phenomenon. Methods: Forty-six patients with advanced NSCLC were enrolled for a bioequivalence study of two pemetrexed formulations. All patients received the pemetrexed-platinum doublet for six cycles followed by single-agent pemetrexed maintenance until progression. Pharmacokinetic blood samples were collected at predefined time points during the first cycle and the concentration-time profile of pemetrexed was investigated by noncompartmental analysis. Hyponatremic episodes were investigated with serum electrolytes, serum osmolality, urinary sodium, and urine osmolality. Results: Sixteen of 46 patients (35% had at least one episode of grade ≥3 hyponatremia. Twenty-four episodes of grade ≥3 hyponatremia were observed in 200 cycles of doublet chemotherapy. Plasma exposure to pemetrexed was significantly higher in patients with high-grade hyponatremia than in those with low-grade or no hyponatremia (P=0.063 and P=0.001, respectively. Pemetrexed clearance in high-grade hyponatremia was quite low compared with normal and low-grade hyponatremia (P=0.001 and P=0.055, respectively. Median pemetrexed exposure in this cohort was much higher than that reported in the literature from Western studies. Conclusion: Higher exposure to

This molecular feature is more frequent in young patients, with no/light smoking habit and with adenocarcinoma pathological subtype. Crizotinib is a tyrosine kinase inhibitor, targeting ALK, ROS1, RON, and MET. The preclinical efficacy results led to a fast-track clinical development. The US Food and Drug Administration (FDA approval was achieved after the Phase I clinical trial in 2011 in ALK-rearranged advanced NSCLC progressing after a first-line treatment. In 2013, the randomized Phase III trial PROFILE-1007 confirmed the efficacy of crizotinib in ALK-rearranged NSCLC, compared to cytotoxic chemotherapy, in second-line setting or more. In 2014, the PROFILE-1014 trial showed the superiority of crizotinib in the first-line setting compared to the pemetrexed platinum doublet chemotherapy. The response rate was 74%, and the progression-free survival was 10.9 months with crizotinib. Based on these results, crizotinib received approval from the FDA and European Medicines Agency for first-line treatment of ALK-rearranged NSCLC. The various molecular mechanisms at the time of the progression (ALK mutations or amplification, ALK-independent mechanisms encourage performing re-biopsy at the time of progression under crizotinib. The best treatment strategy at the progression (crizotinib continuation beyond progression, switch to second-generation tyrosine kinase inhibitors, or cytotoxic chemotherapy depends on the phenotype of the progression, the

Patients usually do not become symptomatic, and therefore do not seek treatment, until the cancer is advanced and it is too late to employ curative treatment options. New therapeutic options are urgently needed for NSCLC, because even current targeted therapies cure very few patients. Active immunotherapy is an option that is gaining more attention. A delicate and complex interplay exists between the tumor and the immune system. Solid tumors utilize a variety of mechanisms to evade immune detection. However, if the immune system can be stimulated to recognize the tumor as foreign, tumor cells can be specifically eliminated with little systemic toxicity. A number of vaccines designed to boost immunity against NSCLC are currently undergoing investigation in phase III clinical trials. Belagenpumatucel-L, an allogeneic cell vaccine that decreases transforming growth factor (TGF-β in the tumor microenvironment, releases the immune suppression caused by the tumor and it has shown efficacy in a wide array of patients with advanced NSCLC. Melanoma-associated antigen A3 (MAGE-A3, an antigen-based vaccine, has shown promising results in MAGE-A3+ NSCLC patients who have undergone complete surgical resection. L-BLP25 and TG4010 are both antigenic vaccines that target the Mucin 1 protein (MUC-1, a proto-oncogene that is commonly mutated in solid tumors.

    Full Text Available Background and objective Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs has shown a high response rate in the treatment of lung cancer in patients with (EGFR mutation. The aim of this study is to evaluate the relationship between EGFR mutation status in serum and predicting benefit from EGFR-TKIs therapy in patients with advanced non-small cell lung cancer (NSCLC. Methods We examined EGFR mutation status in serum of 80 patients with advanced, EGFR-TKIs given as first-line therapy NSCLC. All patients were received long-term follow-up, and the drug efficacy were observed and evaluated. Results The EGFR mutation in serum was detected in 33.8% (27/80 of NSCLC patients examined, in which exon 19 deletion mutation was present at a frequency of 44.4% (12/27 and exon 21 point mutation was 55.6% (15/27; The response rate to EGFR-TKI in patients with EGFR mutation in serum was (55.6%, 15/27, which was remarkably higher than that in EGFR wild-type patients (17.0%, 9/53, the difference was statistically significant (χ2=0.370, P<0.001; The median progression free survival (PFS of patients with EGFR mutation in serum was remarkably better than that of EGFR wild-type patients (9.8 months vs 5.7 months, P=0.014. Conclusion In patients with advanced, EGFR-positive in serum NSCLC, EGFR-TKIs given as first-line therapy is associated with improved drug efficacy. The results suggest that it is feasible to use serum to detect EGFR mutation, which can predict a benefit from EGFR-TKIs given as first-line therapy.

    Full Text Available To compare the efficacy and toxicities of pemetrexed plus platinum with other platinum regimens in patients with previously untreated advanced non-small cell lung cancer (NSCLC.A meta-analysis was performed using trials identified through PubMed, EMBASE, and Cochrane databases. Two investigators independently assessed the quality of the trials and extracted data. The outcomes included overall survival (OS, progression-free survival (PFS, response rate (RR, and different types of toxicity. Hazard ratios (HRs, odds ratios (ORs and their 95% confidence intervals (CIs were pooled using RevMan software.Four trials involving 2,518 patients with previously untreated advanced NSCLC met the inclusion criteria. Pemetrexed plus platinum chemotherapy (PPC improved survival compared with other platinum-based regimens (PBR in patients with advanced NSCLC (HR = 0.91, 95% CI: 0.83-1.00, p = 0.04, especially in those with non-squamous histology (HR = 0.87, 95% CI: 0.77-0.98, p = 0.02. No statistically significant improvement in either PFS or RR was found in PPC group as compared with PBR group (HR = 1.03, 95% CI: 0.94-1.13, p = 0.57; OR = 1.15, 95% CI: 0.95-1.39, p = 0.15, respectively. Compared with PBR, PPC led to less grade 3-4 neutropenia and leukopenia but more grade 3-4 nausea. However, hematological toxicity analysis revealed significant heterogeneities.Our results suggest that PPC in the first-line setting leads to a significant survival advantage with acceptable toxicities for advanced NSCLC patients, especially those with non-squamous histology, as compared with other PRB. PPC could be considered as the first-line treatment option for advanced NSCLC patients, especially those with non-squamous histology.

    Purpose: To report the results of a prospective, single-institution study evaluating the feasibility of conventional chemoradiation (CRT) followed by stereotactic body radiation therapy (SBRT) as a means of dose escalation for patients with stage II-III non-small cell lung cancer (NSCLC) with residual disease. Methods and Materials: Patients without metastatic disease and with radiologic evidence of limited residual disease (≤5 cm) within the site of the primary tumor and good or complete nodal responses after standard CRT to a target dose of 60 Gy were considered eligible. The SBRT boost was done to achieve a total combined dose biological equivalent dose >100 Gy to the residual primary tumor, consisting of 10 Gy × 2 fractions (20 Gy total) for peripheral tumors, and 6.5 Gy × 3 fractions (19.5 Gy total) for medial tumors using the Radiation Therapy Oncology Group protocol 0813 definitions. The primary endpoint was the development of grade ≥3 radiation pneumonitis (RP). Results: After a median follow-up of 13 months, 4 patients developed acute grade 3 RP, and 1 (2.9%) developed late and persistent grade 3 RP. No patients developed grade 4 or 5 RP. Mean lung dose, V2.5, V5, V10, and V20 values were calculated for the SBRT boost, and none were found to significantly predict for RP. Only advancing age (P=.0147), previous smoking status (P=.0505), and high CRT mean lung dose (P=.0295) were significantly associated with RP development. At the time of analysis, the actuarial local control rate at the primary tumor site was 82.9%, with only 6 patients demonstrating recurrence. Conclusions: Linear accelerator-based SBRT for dose escalation of limited residual NSCLC after definitive CRT was feasible and did not increase the risk for toxicity above that for standard radiation therapy.

    Full Text Available Abstract Background Platinum-based chemotherapy has been a standard therapy for advanced non-small cell lung cancer (NSCLC, but it has high toxicity. In China, Shenqi Fuzheng, a newly developed injection concocted from Chinese medicinal herbs has been reported that may increase efficacy and reduce toxicity when combined with platinum-based chemotherapy, but little is known about it outside of China. The aim of this study was to systematically review the existing clinical evidence on Shenqi Fuzheng Injection(SFI combined with platinum-based chemotherapy for advanced NSCLC. Methods Pubmed, Cochrane Library, EMBASE, CNKI, and CBM search were organized for all documents published, in English and Chinese, until April 2010. The randomized controlled clinical trials were selected based on specific criteria, in which a SFI plus platinum-based chemotherapy treatment group was compared with a platinum-based chemotherapy control group for patients with advanced NSCLC. The quality of studies was assessed by modified Jadad's scale, and Revman 4.2 software was used for data syntheses and analyses. Results Twenty nine studies were included in this review based on our selection criteria. Of them, ten studies were of high quality and the rest were of low quality, according to the modified Jadad scale. The meta-analysis showed there was a statistically significant higher tumor response (RR, 1.19; 95% CI, 1.07 to 1.32; P = 0.001 and performance status ((RR, 1.57; 95% CI, 1.45 to 1.70; P P = 0.016. Conclusions SFI intervention appears to be useful to increase efficacy and reduce toxicity when combined with platinum-based chemotherapy for advanced NSCLC, although this result needs to be further verified by more high-quality trials.

    Background The genotype of epidermal growth factor receptor (EGFR) is associated with tyrosine kinase inhibitor and effectiveness of therapy,but its role in cytotoxic chemotherapy is still unknown.Previous studies indicated that certain EGFR mutations were associated with response and progression free survival following platinum based chemotherapy.Our recent studies have identified that EGFR genotypes in the tumour tissues were not associated with response to the first-line chemotherapy in Chinese patients with advanced non-small cell lung cancer (NSCLC).In this study,we investigated associations of EGFR genotypes from plasma of patients with advanced NSCLC and response to first-line chemotherapy and prognosis.Methods We enrolled 145 advanced NSCLC patients who had received first-line chemotherapy in our department.We examined plasma EGFR genotypes for these patients and associations of EGFR mutations with response to chemotherapy and clinical outcomes.Results There were 54 patients with known EGFR mutations and 91 cases of wild types.No significant difference was detected in the response rate to first-line chemotherapy between mutation carriers and wild-type patients (37.0% vs.31.9%).The median survival time and 1-,2-year survival rates were higher in mutation carriers than wild-types (24months vs.18 months,85.7% vs.65.7% and 43.7% vs.25.9%,P=0.047).Clinical stage (IV vs.Ⅲb),response to the first-line chemotherapy (partial vs.no) and EGFR genotype were independent prognostic factors.Conclusion Plasma EGFR mutations in the Chinese patients with advanced NSCLC is not a predictor for the response to first-line chemotherapy,but an independent prognostic factor indicating longer survival.

    Full Text Available BACKGROUND: The predictive value of thymidylate synthase (TYMS to sensitivity to pemetrexed-based chemotherapy in advanced non-small cell lung cancer (NSCLC patients is controversial. We conducted a meta-analysis of all relevant published data to assess the association of TYMS expression with the clinical outcomes of pemetrexed-based regimen in advanced NSCLC. PATIENTS AND METHODS: We conducted an electronic search using using PubMed, Embase, OVID and Cochrane Library databases and manual search. Pooled odds ratio (OR for the response rate and hazard ratio (HR for the overall survival and progression free survival were calculated using the software Revman 5.0. RESULTS: There were 11 studies (n=798 met our criteria for evaluation. Response rate to pemetrexed-based regimen was significantly higher in patients with low/negative TYMS (OR=2.96, 95%CI [1.81, 4.86] P<0.0001. Patients with low/negative TYMS who were treated with pemetrexed-based regimen had longer progression free survival (HR 0.50, 95%CI [0.41, 0.61] P <0.00001 and overall survival (HR 0.41, 95%CI [0.22, 0.78] P=0.007 than those with high/positive TYMS. CONCLUSIONS: Low/negative TYMS expression was significantly associated with higher response rate, longer median survival and longer progression free survival for advanced NSCLC patients receiving pemtrexed-based chemotherapy. Hence, TYMS may be a potential predictor of sensitivity to pemtrexed-based chemotherapy in advanced NSCLC. Large scale prospective clinical trials are still warranted.

    Full Text Available Nitin Patil, Mohammed Abba, Heike AllgayerDepartment of Experimental Surgery, Medical Faculty Mannheim, University of Heidelberg and Molecular Oncology of Solid Tumors Unit, German Cancer Research Center (DKFZ, Heidelberg, GermanyAbstract: Cancer progression is a highly complex process that is driven by a constellation of deregulated signaling pathways and key molecular events. In non-small-cell lung cancer (NSCLC, as in several other cancer types, the epidermal growth factor receptor (EGFR and its downstream signaling components represent a key axis that has been found not only to trigger cancer progression but also to support advanced disease leading to metastasis. Two major therapeutic approaches comprising monoclonal antibodies and small molecule tyrosine kinase inhibitors have so far been used to target this pathway, with a combination of positive, negative, and inconsequential results, as judged by patient survival indices. Since these drugs are expensive and not all patients derive benefits from taking them, it has become both pertinent and paramount to identify biomarkers that can predict not only beneficial response but also resistance. This review focuses on the chimeric monoclonal antibody, cetuximab, its application in the treatment of NSCLC, and the biomarkers that may guide its use in the clinical setting. A special emphasis is placed on the EGFR, including its structural and mechanistic attributes.Keywords: NSCLC, cetuximab, biomarker, cancer progression

    Objective:To explore the significance of epidermal growth factor receptor (EGFR) gene mutations in targeted therapy for patients with advanced non-small cell lung cancer (NSCLC). Methods:One hundred and seventeen patients with advanced NSCLC admitted in Maternal and Child Health Care Center of Zibo City from Jan., 2011 to Jan., 2014 were performed with EGFR gene detection and then divided into 3 groups according to the detecting results. Patients in group A and group B were given oral geiftinib, 250 mg/d while patients in Group C with docetaxel, 75 mg/m2. Chemotherapy for 3 groups was discontinued until severe adverse reactions or disease progression occurred, or continuous treatment was considered to be unfavorable by the doctors, or patients asked for withdrawal from the study. The relationship between clinicopathological features and EGFR mutations were analyzed. The short-term and long-term efifcacy and adverse reactions of 3 groups were observed. Results:Of the 31 cases with EGFR mutations, there were 16 cases (51.6%) of mutations in exon 19, 14 (45.2%) in exon 21 and 2 (6.45%) in exon 18. No EGFR mutation was found in exon 20. EGFR mutations were associated with histological types of tumors and whether patients were smoking. The median follow-up time was 26 months and 62 patients were dead. None of CR was in 3 groups. The disease control rate (DCR) in group A was obviously higher than that in group B (χ2=9.382,P=0.002), which was also higher in group C than that in group B (χ2=4.674,P=0.031). The 1-year survival rate in group A was obviously higher than that in group B and group C (P Conclusion:EGFR mutations are the main indicators for guiding the targeted therapy for patients with advanced NSCLC.

  3. Gene-guided Gefitinib switch maintenance therapy for patients with advanced EGFR mutation-positive Non-small cell lung cancer: an economic analysis

    International Nuclear Information System (INIS)

    Maintenance therapy with gefitinib notably improves survival in patients with advanced non-small cell lung cancer (NSCLC) and EGFR mutation-positive tumors, but the economic impact of this practice is unclear. A decision-analytic model was developed to simulate 21-day patient transitions in a 10-year time horizon. The clinical data were primarily obtained from the results of a pivotal phase III trial that assessed gefitinib maintenance treatment in patients with advanced NSCLC. The cost data were derived from the perspective of the Chinese health care system. The primary outcome was the incremental cost-effectiveness ratio (ICER) at a willingness-to-pay (WTP) threshold of 3 times the per capita GDP of China. Sensitivity analyses were used to explore the impact of uncertainty regarding the results. The impact of the gefitinib patient assistance program (GPAP) was evaluated. After EGFR genotyping, gefitinib maintenance treatment for advanced NSCLC with EGFR mutations increased the life expectancy by 0.74 years and 0.46 QALYs compared with routine follow-up at an additional cost of $26,149.90 USD ($7,178.20 with the GPAP). The ICER for gefitinib maintenance was $57,066.40 and $15,664.80 per QALY gained (at a 3% discount rate) without and with the GPAP, respectively. The utility of progression free survival, the hazard ratio of progression-free survival for gefitinib treatment and the cost of gefitinib per dose were the three factors that had the greatest influence on the results. These results indicate that gene-guided maintenance therapy with gefitinib with the GPAP might be a cost-effective treatment option

    Full Text Available Abstract Background Basic research of gefitinib (Iressa, ZD1839 has demonstrated the combination effects of gefitinib and chemotherapy were sequence-dependent. To evaluate the efficacy of sequential administration of gefitinib following a minor response or partial response to two to three cycles of chemotherapy, a phase II clinical trial was done in Chinese patients with advanced non-small-cell lung cancer (NSCLC. Methods Thirty-three consecutive patients with advanced NSCLC that had been pretreated with at least one chemotherapeutic regimen and were responding to chemotherapy following 2 to 3 cycles of treatment, entered the trial from May 2004 to February 2006. Patients received gefitinib at an oral dose of 250 mg once daily for 4 weeks. Results Thirty-three patients were evaluable for response and toxicity. The objective response rate was 24.2% (8 of 33(95% CI, 11% to 42%. The symptom improvement rate was 54.5% (18 of 33 (95% CI, 41% to 69%. The median duration of response was 7 months (95%CI, 4.0 to 13.2 months. The median time to disease progression (TTP was 6.5 months (95%CI, 0.7 to 16.6 months. The median overall survival time (OS was 9.8 months (range, 2.1 to 18.0 months, and the actuarial 1-year survival was 36.4%. Toxicity was relatively mild and included only one patient (3.0% with grade 4 diarrhea, 1 (3.0% with grade 3 rash, 1 (3.0% with grade 3 nausea, and 1 with grade 3 vomiting (3.0%. Conclusion Preliminary results suggest that sequential administration of gefitinib following a response to chemotherapy may be beneficial for Chinese patients with advanced NSCLC. Further randomized clinical trials are needed.

    Full Text Available BACKGROUND: Combining targeted therapy has been extensively investigated in previously treated advanced non-small-cell lung cancer (NSCLC, but it is still unclear whether combining targeted therapy might offer any benefits against standard monotherapy with erlotinib. We thus performed a meta-analysis of randomized controlled trials to compare the efficacy and safety of combining targeted therapy versus erlotinib alone as second-line treatment for advanced NSCLC. METHODS: Several databases were searched, including Pubmed, Embase and Cochrane databases. The endpoints were overall survival (OS, progression-free survival (PFS, overall response rate (ORR and grade 3 or 4 adverse event (AEs. The pooled hazard ratio (HR or odds ratio (OR, and 95% confidence intervals (CI were calculated employing fixed- or random-effects models depending on the heterogeneity of the included trials. RESULTS: Eight eligible trials involved 2417 patients were ultimately identified. The intention to treatment (ITT analysis demonstrated that combining targeted therapy significantly improved OS (HR 0.90, 95% CI: 0.82-0.99, p = 0.024, PFS (HR 0.83, 95% CI: 0.72-0.97, p = 0.018, and ORR (OR 1.35, 95% CI 1.01-1.80, P = 0.04. Sub-group analysis based on phases of trials, EGFR-status and KRAS status also showed that there was a tendency to improve PFS and OS in combining targeted therapy, except that PFS for patients with EGFR-mutation or wild type KRAS favored erlotinib monotherapy. Additionally, more incidence of grade 3 or 4 rash, fatigue and hypertension were observed in combining targeted therapy. CONCLUSIONS: With the available evidence, combining targeted therapy seems superior over erlotinib monotherapy as second-line treatment for advanced NSCLC. More studies are still needed to identify patients who will most likely benefit from the appropriate combining targeted therapy.

    Full Text Available Background and objective All the advanced NSCLC patients that received EGFR-TKI therapy will eventually relapse after a period of efficacy. The aim of this study is to investigate the serum biomarkers as potential predictive factors for the efficacy of epidermal growth factor receptor (EGFR tyrosine kinase inhibitor (TKI targeted therapy in advanced non-small cell lung cancer. Methods Twenty self-paired serum samples were collected from 9 advanced NSCLC patients that evaluated as disease control (SD or PR after gefinitib therapy, at the time points of before and after gefinitib treatment but 2 weeks before being evaluated as disease progress. All samples were pre-separated by WCX microbeads, and then detected on the MALDI-TOF-MS platform of Bruker AutoflexTM. ClinProTools (Version: 2.1 was used to analyze the differentially expressed proteins. Results There were 7 protein peaks (m/z, 3242.09, 8 690.36, 2 952.64, 3 224.04, 1 450.51, 1 887.8 and 3 935.73 found statistically differentially expressed between the self-paired samples. Three proteins (3 242.09, 2 952.64 and 3 224.04 were down-regulated and four proteins (8 690.36, 1 450.51, 1 887.8 and 3 935.73 up-regulated in gefinitib treated sera. Conclusion The data here suggest that several specific protein peaks might indicate gefinitib resistance, yet the identities of these proteins and the mechanisms underlying the responsiveness to gefinitib treatment need further investigation.

    Background Insufficient data exist on the results of minimally invasive surgery (MIS) for locally advanced non-small cell lung cancer (NSCLC) traditionally approached by thoracotomy. The use of telerobotic surgical systems may allow for greater utilization of MIS approaches to locally advanced disease. We will review the existing literature on MIS for locally advanced disease and briefly report on the results of a recent study conducted at our institution. Methods We performed a retrospective review of a prospective single institution database to identify patients with clinical stage II and IIIA NSCLC who underwent lobectomy following induction chemotherapy. The patients were classified into two groups (MIS and thoracotomy) and were compared for differences in outcomes and survival. Results From January 2002 to December 2013, 428 patients {397 thoracotomy, 31 MIS [17 robotic and 14 video-assisted thoracic surgery (VATS)]} underwent induction chemotherapy followed by lobectomy. The conversion rate in the MIS group was 26% (8/31) The R0 resection rate was similar between the groups (97% for MIS vs. 94% for thoracotomy; P=0.71), as was postoperative morbidity (32% for MIS vs. 33% for thoracotomy; P=0.99). The median length of hospital stay was shorter in the MIS group (4 vs. 5 days; P<0.001). The 3-year overall survival (OS) was 48.3% in the MIS group and 56.6% in the thoracotomy group (P=0.84); the corresponding 3-year DFS were 49.0% and 42.1% (P=0.19). Conclusions In appropriately selected patients with NSCLC, MIS approaches to lobectomy following induction therapy are feasible and associated with similar disease-free and OS to those following thoracotomy.

    Objective: This is a retrospective study to assess the effectiveness of consolidation radiotherapy (CRT) following palliative chemotherapy in patients with metastatic or locally advanced non-small cell lung cancer (NSCLC) who are not suitable for radical treatment. Methods: This study involved retrospective analysis of a prospective database of Northampton Oncology Centre from January 2005 to December 2010,63 patients with advanced/metastatic NSCLC treated at the oncology centre were enrolled. Patients were either treated with high dose (39/36 Gy /13-12 fractions, group 1) or low dose (20 Gy / 5 fractions, group 2) CRT or those were not offered any CRT (group 3). Results: There was no significant difference between the three groups as regard age, sex, performance status, comorbidities or chemotherapy given. However there was a statistically significant difference as regard the stage P = 0.009 with more stage IV patients at group Ⅱ and Ⅲ compared to group l. The mean survival for the three groups was 27 months, 14 months &15 months, respectively. There was a statistically significant improvement of survival in patients treated with high dose palliative CRT compared to the other two groups (P = 0.006). In multivariate analysis only the radiotherapy dose remains as the only statistical significant factor affecting the survival with hazard ratio 0.372 and confidence interval (0.147-0.726). Conclusion: Despite the limitation of our retrospective study, it is worth considering CRT approach for patients with advanced and metastatic NSCLC - not suitable for radical treatment - who have not progressed on chemotherapy.

Methods One hundred and seventeen advanced NSCLC patients aged 60 or over were treated with GP(GEM+platinum, or NP(NVB+platinum, or TP(TAX+platinum, or other first-line chemotherapeutics plus platinum(OCP after surgery, and their clinical data were then retrospectively studied to look for the relationship of patients' prognosis to clinicopathological factors(gender, operation methods, pathologicaltypes, differentiation, clinical stages.The survival curve was plotted with Kaplan-Meier method, hypothesis test was performed by log-rank, and the independent prognostic factors were screened with Cox proportional hazards regression model. Results Theone-, three- and five-year survival rates of the 117 patients were 47.23%,17.52% and 8.05%, respectively. The progression free survival(PFS of GP, NP, TP and OCP groups were 6.0, 5.2, 6.1 and5.5 months(P>0.05, respectively. The median progression free survival was 5.7 months. Univariate and multivariate analysis showed that the differentiated degrees and clinical stages of elderly NSCLC patients were the independent prognostic factors. Conclusions Clinicopathological factors(differentiated degree andclinical stages are closely related to one-, three- and five-year survival rates of advanced NSCLC in elderly patients who received treatment of first-line chemotherapeutics plus platinum. However, the efficacy ofGP, NP, TP or OCP shows no significant difference.

    Full Text Available Abstract Background Erlotinib and pemetrexed have been approved for the second-line treatment of non-small cell lung cancer (NSCLC. These two agents have different mechanisms of action. Combined treatment with erlotinib and pemetrexed could potentially augment the antitumor activity of either agent alone. In the present study, we investigated the safety profile of combined administration of the two agents in pretreated NSCLC patients. Methods A phase I dose-finding study (Trial registration: UMIN000002900 was performed in patients with stage III/IV nonsquamous NSCLC whose disease had progressed on or after receiving first-line chemotherapy. Patients received 500 mg/m2 of pemetrexed intravenously every 21 days and erlotinib (100 mg at Level 1 and 150 mg at Level 2 orally on days 2–16. Results Twelve patients, nine males and three females, were recruited. Patient characteristics included a median age of 66 years (range, 48–78 years, stage IV disease (nine cases, adenocarcinoma (seven cases and activating mutation-positives in the epidermal growth factor receptor gene (two cases. Treatment was well-tolerated, and the recommended dose of erlotinib was fixed at 150 mg. Dose-limiting toxicities were experienced in three patients and included: grade 3 elevation of serum alanine aminotransferase, repetitive grade 4 neutropenia that required reduction of the second dose of pemetrexed and grade 3 diarrhea. No patient experienced drug-induced interstitial lung disease. Three patients achieved a partial response and stable disease was maintained in five patients. Conclusions Combination chemotherapy of intermittent erlotinib with pemetrexed was well-tolerated, with promising efficacy against pretreated advanced nonsquamous NSCLC.

  11. SU-E-J-244: Development and Validation of a Knowledge Based Planning Model for External Beam Radiation Therapy of Locally Advanced Non-Small Cell Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: The study aims to develop and validate a knowledge based planning (KBP) model for external beam radiation therapy of locally advanced non-small cell lung cancer (LA-NSCLC). Methods: RapidPlan™ technology was used to develop a lung KBP model. Plans from 65 patients with LA-NSCLC were used to train the model. 25 patients were treated with VMAT, and the other patients were treated with IMRT. Organs-at-risk (OARs) included right lung, left lung, heart, esophagus, and spinal cord. DVH and geometric distribution DVH were extracted from the treated plans. The model was trained using principal component analysis and step-wise multiple regression. Box plot and regression plot tools were used to identify geometric outliers and dosimetry outliers and help fine-tune the model. The validation was performed by (a) comparing predicted DVH boundaries to actual DVHs of 63 patients and (b) using an independent set of treatment planning data. Results: 63 out of 65 plans were included in the final KBP model with PTV volume ranging from 102.5cc to 1450.2cc. Total treatment dose prescription varied from 50Gy to 70Gy based on institutional guidelines. One patient was excluded due to geometric outlier where 2.18cc of spinal cord was included in PTV. The other patient was excluded due to dosimetric outlier where the dose sparing to spinal cord was heavily enforced in the clinical plan. Target volume, OAR volume, OAR overlap volume percentage to target, and OAR out-of-field volume were included in the trained model. Lungs and heart had two principal component scores of GEDVH, whereas spinal cord and esophagus had three in the final model. Predicted DVH band (mean ±1 standard deviation) represented 66.2±3.6% of all DVHs. Conclusion: A KBP model was developed and validated for radiotherapy of LA-NSCLC in a commercial treatment planning system. The clinical implementation may improve the consistency of IMRT/VMAT planning

    The combination of gemcitabine plus paclitaxel has been proposed as an alternative to the platinum-based combinations for treatment of advanced non-small-cell lung cancer (NSCLC). However, conflicting results have been reported. This meta-analysis was performed to compare the activity, efficacy, and toxicity of gemcitabine plus paclitaxel versus carboplatin plus either gemcitabine or paclitaxel in patients with untreated advanced NSCLC. Randomized phase II and phase III clinical trials comparing gemcitabine plus paclitaxel with carboplatin plus gemcitabine or paclitaxel were collected from electronic databases (Medline, EMBASE, and the Cochrane Central Register of Controlled Trials), relevant reference lists, and abstract books. The published languages and years were not limited. Pooled odds ratios (ORs) were calculated for the 1-year survival rate (1-year SR), the overall response rate (ORR), and grade 3 and grade 4 toxicities. Four randomized controlled trials (2186 patients) were identified from 2051 reports. They were all published as full-text articles. No significant heterogeneity was detected in these studies. A significant difference in ORR favoring gemcitabine plus paclitaxel over carboplatin-based doublets was observed [OR = 1.20; 95% confidence interval (95% CI) = 1.02-1.42; P = 0.03], whereas the trend toward an improved 1-year SR was not significant (OR = 1.07; 95% CI = 0.91-1.26; P = 0.41). An increased risk of grade 3-4 toxicities for patients receiving carboplatin-based chemotherapy was statistically demonstrated. The gemcitabine plus paclitaxel combination showed an improved ORR and a better toxicity profile but a similar 1-year SR compared to carboplatin-based doublets. For nonplatinum-based chemotherapy, gemcitabine plus paclitaxel is a useful alternative. PMID:20703493

  14. Anaplastic lymphoma kinase gene rearrangements in patients with advanced-stage non-small-cell lung cancer: CT characteristics and response to chemotherapy

    International Nuclear Information System (INIS)

    Few articles have been published on the imaging findings of anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC). To investigate the radiological findings of ALK-positive NSCLC in the advanced stage, CT scans were examined. In addition, the response to chemotherapy was evaluated. Of the 36 patients with ALK-rearranged NSCLC, a mass and a nodule were identified in 17 (47.2%) and 16 (44.4%), respectively, indicating that more than 40% had a small-sized tumor. Overall, 31 (86.1%) patients had lymphadenopathy, seven (19.4%) had extranodal lymph node invasion, and three (8.3%) had lymphangitis. A pleural effusion was seen in 15 patients (41.7%). All but one patient had no ground-glass opacity (GGO) lesions, indicating that most ALK-positive tumors showed a solid growth pattern without GGO on CT. Twenty were evaluable for response to chemotherapy; 10 (50.0%) had a partial response (PR), nine (45.0%) had stable disease (SD), and one (5.0%) had progressive disease (PD) with first-line chemotherapy. With second-line chemotherapy, five (26.3%) had PR, 11 (57.9%) had SD, and three (15.8%) had PD. The five patients with PR were all treated by using crizotinib. Time to progression was 8.2 months with first-line chemotherapy, and 6.0 months with second-line chemotherapy. Advanced-stage ALK-positive tumors have a relatively aggressive phenotype, which cannot be inferred from the size of the tumor alone. ALK-positive patients have a good response to first-line cytotoxic drugs and to crizotinib as second-line therapy, but a relatively poor response to cytotoxic drugs as second-line therapy

  15. Analysis of long-term survival in patients treated with three-dimensional conformal radiotherapy for locally advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Objective: To evaluate the prognostic factors of locally advanced non-small cell lung cancer (LA-NSCLC) treated with three dimensional conformal radiation therapy (3D CRT). Methods: In 106 patients with stage IIIa/IIIb NSCLC treated with 3DCRT from Nov 2000 to Mar 2004, 46 of them were treated with radiotherapy alone, 41 by concurrent chemoradiation, and 19 by sequential chemoradiation. The influence of related prognostic factors on survival was evaluated by univariate and multivariate analysis. The treatment outcome was analyzed by prognostic index model. Results: The 1-, 3- and 5- year overall survival rate was 50.0%, 22.2% and 15.5%, respectively, and the median survival time was 12 months. The univariate analysis showed that the following factors were significantly associated with the longer survival: female, good kamofsky performance status (KPS), squamous cell carcinoma, absence of supraclavicular lymph nodes, no smoking history, hemoglobin ≥130 g/L before treatment, N stage, the maximum diameter of tumor ≤5 cm, the volume of tumor ≤90 cm3, GTV ≤150 cm3 and the radiotherapy efficacy. However, multivariate analysis revealed that no smoking history, hemoglobin ≥130 g/L and GTV ≤150 cm3 were the independent risk factors for predicting the survival. Conclusions: Three dimensional conformal radiation therapy could be effective in the treatment of locally advanced NSCLC. No smoking history, hemoglobin ≥130 g/L and GTV ≤150 cm3 might be the independent risk factors for predicting the survival. Prognostic index model could improve the potential of multivariate analysis in predicting the survival of patients treated with radiotherapy for NSCLC. (authors)

    Full Text Available Our objective is to compare the cost-utility of icotinib and gefitinib for the second-line treatment of advanced non-small cell lung cancer (NSCLC from the perspective of the Chinese healthcare system.Model technology was applied to assess the data of randomized clinical trials and the direct medical costs from the perspective of the Chinese healthcare system. Five-year quality-adjusted life years (QALYs and incremental cost-utility ratios (ICURs were calculated. One-way and probabilistic sensitivity analyses (PSA were performed.Our model suggested that the median progression-free survival (PFS was 4.2 months in the icotinib group and 3.5 months in the gefitinib group while they were 4.6 months and 3.4 months, respectively, in the trials. The 5-year QALYs was 0.279 in the icotinib group and 0.269 in the gefitinib group, and the according medical costs were $10662.82 and $13127.57. The ICUR/QALY of icotinib versus gefitinib presented negative in this study. The most sensitive parameter to the ICUR was utility of PFS, ranging from $-1,259,991.25 to $-182,296.61; accordingly the icotinib treatment consistently represented a dominant cost-utility strategy.The icotinib strategy, as a second-line therapy for advanced NSCLC patients in China, is the preferred strategy relative to gefitinib because of the dominant cost-utility. In addition, icotinib shows a good curative effect and safety, resulting in a strong demand for the Chinese market.

    In a prospective randomized study, 287 patients with advanced non-small cell lung cancer (NSCLC) stage IIIb or IV with ECOG performance status (PS) 0-1 or 2 were randomly assigned to receive either best supportive care (BSC) or supportive care plus combination chemotherapy (IEP regimen: ifosfamide 3 gm/m2 IV with mesna uroprotection, epirubicin 60 mg/m2 IV on day 1 and cisplatin 60 mg/m2 IV on day 2; or MVP regimen: mitomycin-C 8 mg/m2, cisplatin 100 mg/m2 IV on day 1, vinblastine 4 mg/m2 IV on days 1 and 15). Serial assessment of Karnofsky performance status (KPS), modified Functional Living Index-Cancer (T-FLIC) and modified Quality of Life-Index (T-QLI) were used to estimate the quality of life. Interviews were done at entry, at the third month and at 2 months post complete treatment. At least two courses of chemotherapy were considered to be adequate for response evaluation. Patients were treated for a total of four to six courses or until progression of disease. Partial response rates were 40 and 41.7% in IEP and MVP arms. Median survival durations were 5.9 and 8.1 months for the IEP and MVP chemotherapy arms, and 4.1 months for BSC (log-rank test: P = 0.0003). One year survival was 13, 29.8 and 39.3% for the BSC, IEP and MVP regimens, respectively. Two years survival was 7.8, 6.4 and 13.1% for the BSC, IEP and MVP regimens, respectively. Improvement in quality of life (QOL) scores at the first, second and third interview were seen in chemotherapy arms only, not in the BSC arm. We conclude that combination chemotherapy improves the quality of life as well as prolonging the survival of patients with advanced NSCLC.

    Pemetrexed, a novel multi-targeted agent established for the treatment of mesothelioma, has been under investigation for other malignancies, and in recent years particularly for non-small-cell lung cancer (NSCLC). In the present trial we investigated pemetrexed in combination with paclitaxel as front-line treatment in advanced or metastatic NSCLC. Our objectives were to determine the response rate, median and overall survival and toxicity. From April 2005 until May 2006, 51 patients with advanced or metastatic NSCLC were enrolled and 48 were considered evaluable. There were 39 males and nine females, median age 62 years (range 37-81 years), one patient stage IIIA N(2), 23 patients, IIIB and 24, stage IV. All patients had a cytologically- or histologically-confirmed diagnosis. Pemetrexed was administered at a standard dose of 500mg/m(2) and paclitaxel at an escalating dose starting at 135mg/m(2), then 150mg/m(2) and ending at a dose of 175mg/m(2); the level was increased every three patients. Both agents were administered on day 1, repeated every 3 weeks for six courses. A 39.6% partial response rate was observed with a median survival of 14 months. Toxicity was mild with 8.3% grade 3 and 4 neutropenia and other very mild hematologic and non-hematologic adverse reactions. The combination of pemetrexed and paclitaxel at doses of 500mg/m(2) and 175mg/m(2), respectively, has been shown to be an effective combination with very limited toxicity. PMID:17382431

    Background Gefitinib is widely used in patients with advanced non-small-cell lung cancer (NSCLC),in whom chemotherapy had failed.Previous trials reported inconsistent findings regarding the efficacy of gefitinib on overall survival (OS) and progression free survival (PFS).This study was to evaluate the effects of chemotherapy plus gefitinib versus chemotherapy alone on survival of patients with NSCLC.Methods We systematically searched Medline,EmBase,the Cochrane Central Register of Controlled Trials,reference lists of articles,and proceedings of major meetings for relevant literature.Randomized controlled trials (RCTs) comparing chemotherapy with and without gefitinib in the treatment of patients with advanced NSCLC were included in our analysis.The primary endpoints were OS and PFS.Results Of 182 relevant studies,12 were included in the final analysis,which consisted of 6844 patients with NSCLC.Overall,we noted that gefitinib therapy had an 8% improvement in the OS as compared to the gefltinib-free therapy,but this difference was not statistically significant (HR,0.92; 95% C/:0.85-1.00; P=0.051).Furthermore,gefltinib therapy had significantly longer PFS compared to gefitinib-free therapy (HR,0.72; 95% C/ 0.60-0.87,P=0.001).Patients receiving gefitinib therapy also had a more frequent objective response rate (ORR) than the control arm (OR,2.51; 95% C/,1.67-3.78,P <0.001).Rashes,diarrhea,dry skin,pruritus,paronychia,and abnormal hepatic function were more frequent in the gefitinib therapy group.Conclusions Treatment with gefitinib had a clear effect on PFS and ORR,and it might contribute considerably to the OS.Furthermore,there was some evidence of benefit for gefitinib therapy among patients with adenocarcinoma.

    Full Text Available Background: Platinum based doublets chemotherapy are the standard of care for metastatic or advanced non-small cell lung carcinoma. This leads to modest survival advantage and improve quality-of-life. However, patients with advanced or metastatic disease eventually present disease progression and needs second-line systemic therapy in a selected group of patients or other supportive measures. There is very little knowledge available from the literature about the prognostic variables in patients, who receive second-line therapy. Materials and Methods: We retrospectively reviewed 329 patients received second-line treatment from July 2007 to September 2011 in the Department of Radiation Oncology, Burdwan Medical College and Hospital. For statistical analysis, 12 potential prognostic variables included. Univariate and multivariate regression analysis carried out to identify the prognostic variables associated with survival. Results: The results of univariate analysis for overall survival (OS and survival after second-line therapy identified to have prognostic significance: Age, sex, performance status, smoking history, serum lactate dehydrogenase, histopathology, first-line chemotherapy and its response and second-line therapy except the stage at diagnosis and site of failure after first-line therapy. The multivariate Cox regression analysis has shown that only performance and second-line therapy were independent prognostic variables for survival after second-line treatment and above these prognostic factors; age, smoking status and progression free survival also for OS. Conclusion: The performance status has shown consistent result as a prognostic factor in univariate and multivariate analysis for OS and survival after second-line therapy. These findings may also facilitate pretreatment prediction of survival and be used for selecting patients for the correct choice of cytotoxic therapy.

    Objective:To observe the effect of Brucea javanica oil emulsion combined with chemotherapy on the immune function of patients with advanced non-small cell lung cancer (NSCLC). Methods:One hundred and fifty-six patients with NSCLC were randomly divided into treatment group (n=82) treated with Brucea javanica oil emulsion combined with GP regimen chemotherapy and control group (n=74) only with GP regimen chemotherapy. The cellular immunity (CD3+, CD4+, CD8+, CD16+CD56+) and humoral immunity (IgG, IgA, IgM, C3, C4) before and after chemotherapy were tested by lfow cytometry (FCM) and biochemical method, respectively. The inlfuences of two treatment methods on the immune function were compared, and clinical efifcacy was evaluated. Results:The remission rates (RRs) were respectively 40.3% and 36.5% in treatment group and control group, without statistical difference (P>0.05). Compared with chemotherapy before, the cellular immune function after chemotherapy decreased in control group (P<0.05),whereas the levels of CD3+, CD4+, CD4+/CD8+ and CD16+CD56+increased signiifcantly in treatment group (P<0.05 orP<0.01). After chemotherapy, the cellular immune function in treatment group was obviously superior to that in control group, whereas there was no statistical signiifcance by comparison to humoral immune indexes between two groups. Conclusion:With similar efifcacy to control group, Brucea javanica oil emulsion combined with GP regimen chemotherapy can improve the cellular immune function of patients with advanced NSCLC and protect the chemotherapy-induced cellular immune function from damage to a certain extent.

  2. Feasibility study of DCs/CIKs combined with thoracic radiotherapy for patients with locally advanced or metastatic non-small-cell lung cancer

    International Nuclear Information System (INIS)

    The combination of dendritic cells (DCs) and cytokine-induced killer cells (CIKs) can induce the anti-tumor immune response and radiotherapy may promote the activity. We aimed to explore the feasibility of DCs/CIKs combined with thoracic radiotherapy (TRT) for patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC). In this study, patients with unresectable stage III/IV NSCLC and an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0–2 and previously receiving two or more cycles of platinum-based doublet chemotherapy without disease progression received TRT plus DCs/CIKs or TRT alone until disease progression or unacceptable toxicity. The primary endpoint was median progression-free survival (mPFS). In treatment group, patients received four-cycle autologous DCs/CIKs infusion starting from the 6th fraction of irradiation. From Jan 13, 2012 to June 30, 2014, 82 patients were enrolled, with 21 patients in treatment group and 61 in control group. The mPFS in treatment group was longer than that in control group (330 days vs 233 days, hazard ratio 0.51, 95 % CI 0.27–1.0, P < 0.05), and the objective response rate (ORR) of treatment group (47.6 %) was significantly higher that of control group (24.6 %, P < 0.05). There was no significant difference in disease control rate (DCR) and median overall survival (mOS) between two groups (P > 0.05). The side effects in treatment group were mild and there was no treatment-related deaths. The combination of DCs/CIKs with TRT could be a feasible regimen in treating locally advanced or metastatic NSCLC patients. Further investigation of the regimen is warranted

    Purpose: to determine the maximum tolerated dose (MTD) of gemcitabine every 2 weeks to a concurrent radiotherapy administered during an aggressive program of sequential and simultaneous radio-/chemotherapy for locally advanced, unresectable non-small cell lung cancer (NSCLC). Patients and methods: ten patients with histologically confirmed NSCLC were observed and treated in accordance with a combined radio-/chemotherapy protocol. This included two cycles of induction chemotherapy with gemcitabine (1,200 mg/m{sup 2}) and vinorelbine (30 mg/m{sup 2}) at days 1, 8 and 22, 29, followed by concurrent radiotherapy including [{sup 18}F] fluorodeoxyglucose positron emission tomography-(FDG-PET-) based target volume definition (2.0 Gy/d; total dose 66.0 Gy) and chemotherapy with gemcitabine every 2 weeks at days 43, 57, and 71. The initial dose was 300 mg/m{sup 2}. The dose of gemcitabine was increased by 100 mg/m{sup 2} until the MTD was realized. Three patients were enrolled for each dose level. Results: dose-limiting toxicity (DLT) was identified for the patient group receiving gemcitabine 500 mg/m{sup 2}, due to grade 2 esophagitis (next to grade 3) in all patients. 6 weeks after the completion of radio-/chemotherapy, most patients still presented treatment-induced esophagitis. In accordance with expected complications, such as esophagitis, dysphagia and odynophagia, the MTD was defined at this dose level, although no DLT grade 3 was reached. Conclusion: after induction chemotherapy, the MTD and frequency of gemcitabine in locally advanced NSCLC is 500 mg/m{sup 2} every 2 weeks during a maximum of 7 weeks of thoracic radiotherapy.

    Background and objective Recent studies have showed that combination of chemotherapy and radiotherapy might result in better outcome for locally advanced non-small cell lung cancer (NSCLC). The aim of this study is to determine the maximal tolerance dose (MTD) and efficacy of full-dose gemcitabine and oxaliplatin when given concurrently with 3-dimentional radiation therapy (3D-RT) for locally advanced NSCLC. Methods Oxaliplatin was administered at a fixed dose of 130 mg/m2, and gemcitabine was administered at a starting dose of 800 mg/m2 with an incremental dose gradient of 200 mg/m2 for 3 dose levels. MTD was defined as the immediate dose level lower than the dose at which dose-limiting toxicity (DLT) occurred in more than one-third of the patients. The chemotherapy was administered at 3-week cycle. The RT was given as 3-D conformal manner at a single daily dose of 2 Gy for 5 days per week. Results Twenty-two patients were evaluable and distributed to three different dose levels: 6 at level 1, 8 at level 2 and 8 at level 3. Pulmonary toxicity, esophageal and hematologic toxicity were the main DLT. Grade Ⅲ acute pulmonary toxicity occurred in one patient each at level 2 and level 3, both with V20>20%, and grade Ⅲ esophagitis in two patients at level 3. The MTD of gemcitabine in this study was 1000 mg/m2. The overall response rate was 75.0% (9/12). The 1- and 2-year survival rate was 70.0% and 30.5% respectively. The median time to progression was 8.7 months (range 5--11.8 months). Conclusion With reduced radiation volume, gemcitabine of 1000 mg/m2 in combination with oxaliplatin of 130 mg/m2 was effective and could be safely administered for NSCLC.

    Non-small cell lung cancer (NSCLC) unfortunately carries a very poor prognosis. Patients usually do not become symptomatic, and therefore do not seek treatment, until the cancer is advanced and it is too late to employ curative treatment options. New therapeutic options are urgently needed for NSCLC, because even current targeted therapies cure very few patients. Active immunotherapy is an option that is gaining more attention. A delicate and complex interplay exists between the tumor and the immune system. Solid tumors utilize a variety of mechanisms to evade immune detection. However, if the immune system can be stimulated to recognize the tumor as foreign, tumor cells can be specifically eliminated with little systemic toxicity. A number of vaccines designed to boost immunity against NSCLC are currently undergoing investigation in phase III clinical trials. Belagenpumatucel-L, an allogeneic cell vaccine that decreases transforming growth factor (TGF-β) in the tumor microenvironment, releases the immune suppression caused by the tumor and it has shown efficacy in a wide array of patients with advanced NSCLC. Melanoma-associated antigen A3 (MAGE-A3), an antigen-based vaccine, has shown promising results in MAGE-A3+ NSCLC patients who have undergone complete surgical resection. L-BLP25 and TG4010 are both antigenic vaccines that target the Mucin-1 protein (MUC-1), a proto-oncogene that is commonly mutated in solid tumors. CIMAVax is a recombinant human epidermal growth factor (EGF) vaccine that induces anti-EGF antibody production and prevents EGF from binding to its receptor. These vaccines may significantly improve survival and quality of life for patients with an otherwise dismal NSCLC prognosis. This review is intended to give an overview of the current data and the most promising studies of active immunotherapy for NSCLC.

    The Oncology Grand Rounds series is designed to place original reports published in theJournal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published inJournal of Clinical Oncology, to patients seen in their own clinical practice.A 78-year-old woman with a 40-pack-year smoking history has been referred for treatment of advanced non-small-cell lung cancer. She presented with a persistent cough and worsening dyspnea on exertion. A chest x-ray followed by a chest computed tomography scan revealed a 3-cm right upper lobe mass along with a moderate-size pleural effusion. Pleural fluid cytology was positive for adenocarcinoma. A brain magnetic resonance imaging scan was negative. A reflex molecular profile, includingKRAS,EGFR,ALK,BRAF,HER2,RET,MET, andROS, did not reveal an actionable abnormality. Her past medical history includes diabetes, hypertension, and osteopenia. Her medications include a β-blocker, angiotensin-converting enzyme inhibitor, oral antidiabetic agent, calcium, and vitamin D. The laboratory evaluation is notable for a hemoglobin of 10.8 g/dL and a creatinine clearance of 36 mL/min. The other laboratories are within normal limits. She is somewhat limited by the shortness of breath but maintains an Eastern Cooperative Oncology Group performance status of 1. She is independent in all of her instrumental and basic activities of daily living and denies falls. She has been referred to discuss treatment options. PMID:27001591

    Treatment related death (TRD) is the worst adverse event in chemotherapy and radiotherapy for patients with cancer, the reports for TRDs were sporadically. We aimed to study TRDs in non-small cell lung cancer (NSCLC) patients treated with concurrent chemoradiotherapy (CCRT), and determine whether high radiation dose and newer chemotherapy regimens were associated with the risk of TRD. Data from randomized clinical trials for locally advanced/unresectable NSCLC patients were analyzed. Eligible studies had to have at least one arm with CCRT. The primary endpoint was TRD. Pooled odds ratios (ORs) for TRDs were calculated. In this study, a total of fifty-three trials (8940 patients) were eligible. The pooled TRD rate (accounting for heterogeneity) was 1.44% for all patients. In 20 trials in which comparison of TRDs between CCRT and non-CCRT was possible, the OR (95% CI) of TRDs was 1.08 (0.70–1.66) (P = 0.71). Patients treated with third-generation chemotherapy and concurrent radiotherapy had an increase of TRDs compared to those with other regimens in CCRT (2.70% vs. 1.37%, OR = 1.50, 95% CI: 1.09–2.07, P = 0.008). No significant difference was found in TRDs between high (≥ 66 Gy) and low (< 66 Gy) radiation dose during CCRT (P = 0.605). Neither consolidation (P = 0.476) nor induction chemotherapy (P = 0.175) had significant effects with increased TRDs in this study. We concluded that CCRT is not significantly associated with the risk of TRD compared to non-CCRT. The third-generation chemotherapy regimens may be a risk factor with higher TRDs in CCRT, while high dose radiation is not significantly associated with more TRDs. This observation deserves further study. PMID:27300551

  9. Non-small cell lung cancer: current status of chemoradiation for locally advanced disease and an update on susceptibility and prevention

    International Nuclear Information System (INIS)

    Locally advanced, inoperable non-small cell lung cancer (NSCLC) afflicts 40,000 patients yearly. The traditional treatment has been radiation therapy (RT) alone with 5 year survival rates averaging around 5%. Recent reports of randomized clinical trials using combined radiochemotherapy suggest significant improvement in survival compared to RT alone. These trials are difficult to evaluate because of differences in dose, timing and sequencing of both the chemotherapy (CT) and the RT. Dr. Byhardt will give an overview of the significant chemoradiation trials, especially with respect to the factors associated with reduction of local failure and distant metastasis. Dr. Tishler will review the biologic rationale of these regimens and make some prognostications about the potential role of new chemotherapy agents, new developments in RT dose-time-fractionation, and new RT technology in future radiochemotherapy trials. While progress continues to be made using the more traditional cancer treatment modalities, investigations in NSCLC epidemiology and prevention are providing new insights regarding susceptibility, etiology, failure risk stratification, and potential avenues of therapeutic intervention. Dr. Spitz will discuss NSCLC as a paradigm of an environmentally induced disease in which host susceptibility may be determined by genetically determined modulation of environmental exposures. A mutagen sensitivity assay can determine individuals at high risk for developing NSCLC if exposed to carcinogens such as those in cigarette smoke. This susceptibility may have prognostic implications that could influence choice of therapy. Highly susceptible individuals can also be selected for special counseling, smoking cessation, with consideration given to chemoprevention. Dr. Gritz will review major work done in this area

  10. High plasma exposure to pemetrexed leads to severe hyponatremia in patients with advanced non small cell lung cancer receiving pemetrexed-platinum doublet chemotherapy

    International Nuclear Information System (INIS)

    Pemetrexed-platinum doublet therapy is a standard treatment for stage IIIb/IV nonsquamous non small cell lung cancer (NSCLC). While the regimen is associated with several grade ≥3 toxicities, hyponatremia is not a commonly reported adverse effect. Here we report an unusually high incidence of grade ≥3 hyponatremia in Indian patients receiving pemetrexed-platinum doublet, and the pharmacological basis for this phenomenon. Forty-six patients with advanced NSCLC were enrolled for a bioequivalence study of two pemetrexed formulations. All patients received the pemetrexed-platinum doublet for six cycles followed by single-agent pemetrexed maintenance until progression. Pharmacokinetic blood samples were collected at predefined time points during the first cycle and the concentration-time profile of pemetrexed was investigated by noncompartmental analysis. Hyponatremic episodes were investigated with serum electrolytes, serum osmolality, urinary sodium, and urine osmolality. Sixteen of 46 patients (35%) had at least one episode of grade ≥3 hyponatremia. Twenty-four episodes of grade ≥3 hyponatremia were observed in 200 cycles of doublet chemotherapy. Plasma exposure to pemetrexed was significantly higher in patients with high-grade hyponatremia than in those with low-grade or no hyponatremia (P=0.063 and P=0.001, respectively). Pemetrexed clearance in high-grade hyponatremia was quite low compared with normal and low-grade hyponatremia (P=0.001 and P=0.055, respectively). Median pemetrexed exposure in this cohort was much higher than that reported in the literature from Western studies. Higher exposure to pemetrexed is associated with grade ≥3 hyponatremia. The pharmacogenetic basis for higher exposure to pemetrexed in Indian patients needs further investigation

    Full Text Available This study aimed to evaluate the safety, tolerability and pharmacokinetics of the combination of oral vinorelbine with erlotinib using the conventional (CSV and metronomic (MSV dosing schedules in patients with advanced non-small cell lung cancer (NSCLC.This was an open-label, multiple dose-escalation phase I study. An alternating 3+3 phase I design was employed to allow each schedule to enroll three patients sequentially at each dose level. Thirty patients with Stage IIIB/IV NSCLC were treated with escalating doses of oral vinorelbine starting at 40 mg/m2 on day 1 and 8 in the CSV group (N = 16 and at 100 mg/week in the MSV group (N = 14. Erlotinib was administered orally daily.The maximum tolerated dose was vinorelbine 80 mg/m2 with erlotinib 100 mg in the CSV group and vinorelbine 120 mg/week with erlotinib 100 mg in the MSV group. Grade 3/4 toxicities included neutropenia (N = 2; 13% and hyponatremia (N = 1; 6% in the CSV group, and neutropenia (N = 5; 36% in the MSV group. Objective response was achieved in 38% and 29% in the CSV and MSV groups respectively. Vinorelbine co-administration did not significantly affect the pharmacokinetics of erlotinib and OSI-420 after initial dose. However, at steady-state, significantly higher Cmax, higher Cmin and lower CL/F of erlotinib were observed with increasing dose levels of vinorelbine in the CSV group. Significantly higher steady-state Cmin, Cavg and AUCss of erlotinib were observed with increasing dose levels of vinorelbine in the MSV group.Combination of oral vinorelbine with erlotinib is feasible and tolerable in both the CSV and MSV groups.ClinicalTrials.gov NCT00702182.

    Background: Preoperative concurrent chemoradiotherapy (CRT) is an accepted treatment for potentially resectable, locally advanced, non-small-cell lung cancer (NSCLC). We reviewed a decade of single institution experience with preoperative split-course CRT followed by surgical resection to evaluate survival and identify factors that may be helpful in predicting outcome. Methods and Materials: All patients treated with preoperative split-course CRT and resection at Rush University Medical Center (RUMC) between January 1999 and December 2008 were retrospectively analyzed. Endpoints included overall survival (OS), progression-free survival (PFS), local-regional progression-free survival (LRPFS), and distant metastasis-free survival (DMFS). Patient and treatment related variables were assessed for correlation with outcomes. Results: A total of 54 patients were analyzed, 76% Stage IIIA, 18% Stage IIIB, and 6% oligometastatic. The pathologic complete response (pCR) rate was 31.5%, and the absence of nodal metastases (pN0) was 64.8%. Median OS and 3-year actuarial survival were 44.6 months and 50%, respectively. Univariate analysis revealed initial stage (p < 0.01) and percent weight change during CRT (p < 0.01) significantly correlated with PFS/OS. On multivariate analysis initial stage (HR, 2.4; 95% CI, 1.18-4.90; p = 0.02) and percent weight change (HR, 0.79; 95% CI, 0.67-0.93; p < 0.01) maintained significance with respect to OS. There were no cases of Grade 3+ esophagitis, and there was a single case of Grade 3 febrile neutropenia. Conclusions: The strong correlation between weight change during CRT and OS/PFS suggests that this clinical parameter may be useful as a complementary source of predictive information in addition to accepted factors such as pathological response.

    Background Platinum-based chemotherapy has been proved effective in patients with advanced non-small cell lung cancer (NSCLC). This study evaluated the effectiveness and safety of first-line chemotherapy with gemcitabine plus cisplatin (GEM-Cis) 3-week regimen in routine care of Chinese patients with advanced NSCLC.Methods Two hundred and twenty-one patients with NSCLC stage IIIb or IV were enrolled and 209 were eligible foreffectiveness and safety analysis. The median age was 58 (range 29 to 79) years. The percents of cases in stage Ⅳ and stage Ⅲb were 52.2% and 47.8%; of Karnofsky performance score (KPS) less than 80 and 80-100 were 37.3% and 62.7% and of adeno-cancer and non-adeno-cancer were 59.8% and 40.2%. The average number of completed chemotherapy cycles was three. Measures of effectiveness included clinical benefit, significant clinical response (SCR) and adverse effects of GEM-Cis in the treatment of NSCLC at stages Ⅲb/Ⅳ.Results KPS increased from 79±9 at baseline to 86±10 after chemotherapy (P<0.01). Lung cancer symptom scale (LCSS) score of pain, dyspnea and cough increased from 77±24, 74±22 and 63±19 to 92±15, 90±14 and 86±15, respectively (P<0.01). The clinical benefit rate was 85.2% [95% confidence interval (CI) 80.3%-90.0%]. The SCR was 89.5% (95% CI 85.3%-93.7%). Median survival time was 7.8 months (95% CI 7.1 months-9.1 months). Sixty-four patients (30.6%) experienced an adverse effect that was deemed clinically significant. Only one patient (0.5%) was hospitalized due to chemotherapy related adverse effects. Life-threatening toxicity was observed in two patients (1.0%).Conclusion First-line chemotherapy with GEM-Cis in the routine care of Chinese patients with advanced NSCLC is effective and safe.

    Full Text Available Background and Objectives: Non-small-cell lung cancer (NSCLC represents approximately 80% of all lung cancers. Unfortunately, at their time of diagnosis, most patients have advanced to unresectable disease with a very poor prognosis. The oriental herbal medicine HangAm-Plus (HAP has been developed for antitumor purposes, and several previous studies have reported its therapeutic effects. In this study, the efficacy of HAP was evaluated as a third-line treatment for advanced-stage IIIb/IV NSCLC. Methods: The study involved six patients treated at the East- West Cancer Center (EWCC from April 2010 to October 2011. Inoperable advanced-stage IIIb/IV NSCLC patients received 3,000 or 6,000 mg of HAP on a daily basis over a 12-week period. Computed tomography (CT scans were obtained from the patients at the time of the initial administration and after 12 weeks of treatment. We observed and analyzed the patients overall survival (OS and progression-free survival (PFS. Results: Of the six patients, three expired during the study, and the three remaining patients were alive as of October 31, 2011. The OS ranged from 234 to 512 days, with a median survival of 397 days and a one-year survival rate of 66.7%. In the 12-week-interval chest CT assessment, three patients showed stable disease (SD, and the other three showed progressive disease (PD. The PFS of patients ranged from 88 to 512 days, the median PFS being 96 days. Longer OS and PFS were correlated with SD. Although not directly comparable, the OS and the PFS of this study were greater than those of the docetaxel or the best supportive care group in other studies. Conclusion: HAP may prolong the OS and the PFS of inoperable stage IIIb/IV NSCLC patients without significant adverse effects. In the future, more controlled clinical trials with larger samples from multi-centers should be conducted to evaluate the efficacy and the safety of HAP.

  16. Tumor response and survival in patients with advanced non-small-cell lung cancer: the predictive value of chemotherapy-induced changes in fibrinogen

    International Nuclear Information System (INIS)

    Hyperfibrinogenemia is a common problem associated with various carcinomas, and is accompanied by hypercoagulablity. In advanced non-small-cell lung cancer (NSCLC) it remains unclear whether or not chemotherapy-induced changes in fibrinogen level relate to chemotherapeutic response and prognosis. The purposes of this study were to: 1) analyze the association between chemotherapy-induced changes in plasma fibrinogen level and the chemotherapeutic response after the first two courses of standard first-line platinum-based chemotherapy; and 2) evaluate the prognostic significance of the basal plasma fibrinogen level in patients with advanced NSCLC. In this retrospective study, the data from 160 patients with advanced NSCLC were collected. The association between the changes in fibrinogen and the response to chemotherapy, or between the pre-and post-chemotherapy fibrinogen levels and patient clinical characteristics, were analyzed using SPSS software. In addition, the prognostic value of pre-chemotherapy fibrinogen levels was assessed. The median pre-chemotherapy plasma fibrinogen level was 4.4 g/L. Pre-chemotherapy plasma fibrinogen levels correlated significantly with gender (p = 0.041). Post-chemotherapy plasma fibrinogen levels correlated with gender (p = 0.023), age (p = 0.018), ECOG (p = 0.002) and tumor response (p = 0.049). Plasma fibrinogen levels markedly decreased after chemotherapy in 98 (61.25 %) patients with pre-chemotherapy hyperfibrinogenemia (p = 0.008); and in this population there was a significant link between the decrease in fibrinogen level, and initial partial response (PR; p = 0.017) and stable disease (SD; p = 0.031). Univariate and multivariate analysis revealed that higher levels of fibrinogen (≥4.4 g/L) and ECOG 1 were positively associated with shorter overall survival (OS). CEA and CA125 also decreased significantly (p =0.015, p =0.000) in DCR group after chemotherapy. This study showed that the reduction in plasma fibrinogen levels

    Full Text Available Lung cancer ranks the first position in morbidity and mortality among all malignances in China. Non-small cell lung cancer (NSCLC accounts for nearly 80% of all lung malignancies. Surgical resection is still the current major treatment method for early stage NSCLC. Lymph node stages together with the extent of lymph node dissection directly affect the prognosis. Anatomical lobectomy with systematic mediastinal lymph node dissection have been the standard surgical treatment for NSCLC. However, it is controversial in the extent of lymph node dissection for early stage NSCLC. Accurate nodes stage and the extent of mediatinal nodes dissection affect the peri-operative complications and the prognosis of NSCLC greatly. In the past decade, more and more surgeons demostrated that lobe-specific or selective mediastinal lymph node dissection is suitable for clinical stage I NSCLC, especially the stage Ia lesions, and may become the standard lymph node dissection mode in the future.

  18. The cost-effectiveness and cost-utility of high-dose palliative radiotherapy for advanced non-small-cell lung cancer

    International Nuclear Information System (INIS)

    Purpose: To compute cost-effectiveness/cost-utility (CE/CU) ratios, from the treatment clinic and societal perspectives, for high-dose palliative radiotherapy treatment (RT) for advanced non-small-cell lung cancer (NSCLC) against best supportive care (BSC) as comparator, and thereby demonstrate a method for computing CE/CU ratios when randomized clinical trial (RCT) data cannot be generated. Methods and Materials: Unit cost estimates based on an earlier reported 1989-90 analysis of treatment costs at the Vancouver Island Cancer Centre, Victoria, British Columbia, Canada, are updated to 1997-1998 and then used to compute the incremental cost of an average dose of high-dose palliative RT. The incremental number of life days and quality-adjusted life days (QALDs) attributable to treatment are from earlier reported regression analyses of the survival and quality-of-life data from patients who enrolled prospectively in a lung cancer management cost-effectiveness study at the clinic over a 2-year period from 1990 to 1992. Results: The baseline CE and CU ratios are $9245 Cdn per life year (LY) and $12,836 per quality-adjusted life year (QALY), respectively, from the clinic perspective; and $12,253/LY and $17,012/QALY, respectively, from the societal perspective. Multivariate sensitivity analysis for the CE ratio produces a range of $5513-28,270/LY from the clinic perspective, and $7307-37,465/LY from the societal perspective. Similar calculations for the CU ratio produce a range of $7205-37,134/QALY from the clinic perspective, and $9550-49,213/QALY from the societal perspective. Conclusion: The cost effectiveness and cost utility of high-dose palliative RT for advanced NSCLC compares favorably with the cost effectiveness of other forms of treatment for NSCLC, of treatments of other forms of cancer, and of many other commonly used medical interventions; and lies within the US $50,000/QALY benchmark often cited for cost-effective care

    BCL-2 Associated athanogene 1 (BAG-1) and Xeroderma pigmentosum group D (XPD) are involved in the nucleotide excision repair pathway and DNA repair. We aimed to investigate whether polymorphisms in BAG-1 and XPD have effects on chemotherapy sensitivity and survival in patients with advanced non-small-cell lung cancer (NSCLC) treated with vinorelbine combined cisplatin (NP) regimen. A total of 142 patients with diagnosed advanced NSCLC were recruited in the current study. NP regimen was applied for all eligible patients. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used for BAG-1 (codon 324) and XPD (codons 312 and 751) genotyping. The treatment response was evaluated according to the RECIST guidelines. Progression-free survival (PFS) and overall survival (OS) were record as median and end point, respectively. As for BAG-1 codon 324, the chemotherapy sensitivity in NSCLC patients with CT genotype was 0.383 times of those with CC genotype (P < 0.05). With respect to XPD codon 751, the chemotherapy sensitivity in NSCLC patients with Lys/Gln genotype was 0.400 times of those with Lys/Lys genotype (P < 0.05). In addition, NSCLC patients carrying combined C/C genotype at codon 324 in BAG-1, Asp/Asp of XPD codon 312, and Lys/Lys of XPD codon 751 produced a higher efficacy of NP chemotherapy compared to those carrying mutation genotypes (all P < 0.05). Further, there were significant differences in PFS between patients with combined C/C genotype of BAG-1 codon 324, Lys/Lys genotype of XPD codon 751, and Asp/Asp genotype of XPD codon 312 and patients carrying BAG-1 codon 324 C/T genotype, XPD codon751 Lys/Gln genotype, and XPD codon312 Asp/Asn genotype (P < 0.05). Multivariate Cox regression analysis indicated that the combined wild-type of codon 324 XPD, codon 751 XPD, and codon 312 BAG-1 is the protective factor for OS and PFS, and clinical stages is the risk factor for OS and PFS. In conclusion, our research

    Full Text Available Abstract Objective: To explore the significance of epidermal growth factor receptor (EGFR gene mutations in targeted therapy for patients with advanced non-small cell lung cancer (NSCLC. Methods: One hundred and seventeen patients with advanced NSCLC admitted in Maternal and Child Health Care Center of Zibo City from Jan., 2011 to Jan., 2014 were performed with EGFR gene detection and then divided into 3 groups according to the detecting results. Patients in group A and group B were given oral gefitinib, 250 mg/d while patients in Group C with docetaxel, 75 mg/m2. Chemotherapy for 3 groups was discontinued until severe adverse reactions or disease progression occurred, or continuous treatment was considered to be unfavorable by the doctors, or patients asked for withdrawal from the study. The relationship between clinicopathological features and EGFR mutations were analyzed. The short-term and long-term efficacy and adverse drug reactions of 3 groups were observed. Results: Of the 31 cases with EGFR mutations, there were 16 cases (51.6% of mutations in exon 19, 14 (45.2% in exon 21 and 2 (6.45% in exon 18. No EGFR mutation was found in exon 20. EGFR mutations were associated with histological types of tumors and whether patients were smoking. The median follow-up time was 26 months and 62 patients were dead. None of CR was in 3 groups. The disease control rate (DCR in Group A was obviously higher than that in Group B ( χ 2 =9.382, P=0.002, which was also higher in Group C than that in Group B ( χ 2 =4.674, P=0.031. The 1-year survival rate in Group A was obviously higher than that in group B and group C ( P <0.05, or P<0.01 , which was prominently higher in Group C than that in Group B ( P <0.01 . The median progression-free survival (PFS and median overall survival (OS were the longest in Group A was and the shortest in Group B. The adverse reactions of two kinds of

    Full Text Available Background: Platinum-based doublet chemotherapy is the backbone of treatment in advanced non-small cell lung cancer (NSCLC however second-line treatment options are controversial particularly in patients with borderline performance status (PS of 2. The aim of this study was to compare efficacy and toxicity of weekly docetaxel versus gemcitabine in this clinical setting. Patients and methods: A total of 70 patients with advanced (stage IIIB, IV NSCLC entered this single institute study. Cases of this study had experienced disease progression after the first-line platinum-based doublet chemotherapy, with PS 0- 2 in “Eastern Cooperative Oncology Group” scale. They were randomly assigned by stratified blocks to receive docetaxel 35 mg/m2 (Arm A, n=34 or gemcitabine 1000 mg/m2 (Arm B, n=36 days 1, 8 and 15, every three weeks, for up to six cycles. Primary end point was progression free survival (PFS and secondary end points were objective response rate, disease control rate, median overall survival (OS and toxicity. Dose modification was permitted upon clinician’s discretion for each individual patient. Results: Median of PFS was 2.02 months in arm A and 2.63 months in arm B (HR= 1.279; 95% CI: 0.710-2.304, P= 0.551. Although median OS for arm A was numerically greater (9.2 months than arm B (8.3 months it was statistically non-significant (HR= 1.384; 95% CI: 0.632 to 2.809, P= 0.59. Objective response was higher in Arm B than that in Arm A (P= 0.20 but disease control rates were statistically different in both arms (P= 0.034. Statistically significant differences in term of leukopenia was seen in arm B (P= 0.013. Conclusion: This study, with limited number of cases, indicates that in advanced NSCLC, weekly docetaxel and gemcitabine are reasonable second-line treatment options with statistically similar effectiveness in terms of PFS and median OS with manageable toxicities in patients with PS 0-2.

    Full Text Available Many published studies reflect the growing application of complementary and alternative medicine, particularly Chinese herbal medicine (CHM use in combination with conventional cancer therapy for advanced non-small cell lung cancer (NSCLC, but its efficacy remains largely unexplored. The purpose of this study is to evaluate the efficacy of CHM combined with conventional chemotherapy (CT in the treatment of advanced NSCLC. Publications in 11 electronic databases were extensively searched, and 24 trials were included for analysis. A sum of 2,109 patients was enrolled in these studies, at which 1,064 patients participated in CT combined CHM and 1,039 in CT (six patients dropped out and were not reported the group enrolled. Compared to using CT alone, CHM combined with CT significantly increase one-year survival rate (RR = 1.36, 95% CI = 1.15-1.60, p = 0.0003. Besides, the combined therapy significantly increased immediate tumor response (RR = 1.36, 95% CI = 1.19-1.56, p<1.0E-5 and improved Karnofsky performance score (KPS (RR = 2.90, 95% CI = 1.62-5.18, p = 0.0003. Combined therapy remarkably reduced the nausea and vomiting at toxicity grade of III-IV (RR = 0.24, 95% CI = 0.12-0.50, p = 0.0001 and prevented the decline of hemoglobin and platelet in patients under CT at toxicity grade of I-IV (RR = 0.64, 95% CI = 0.51-0.80, p<0.0001. Moreover, the herbs that are frequently used in NSCLC patients were identified. This systematic review suggests that CHM as an adjuvant therapy can reduce CT toxicity, prolong survival rate, enhance immediate tumor response, and improve KPS in advanced NSCLC patients. However, due to the lack of large-scale randomized clinical trials in the included studies, further larger scale trials are needed.

  3. Role of survival post-progression in phase III trials of systemic chemotherapy in advanced non-small-cell lung cancer: a systematic review.

    Katsuyuki Hotta

    Full Text Available BACKGROUND: In advanced non-small-cell lung cancer (NSCLC, with the increasing number of active compounds available in salvage settings, survival after progression to first-line chemotherapy seems to have improved. A literature survey was conducted to examine whether survival post-progression (SPP has improved over the years and to what degree SPP correlates with overall survival (OS. METHODS AND FINDINGS: Median progression-free survival (MPFS time and median survival time (MST were extracted in phase III trials of first-line chemotherapy for advanced NSCLC. SPP was pragmatically defined as the time interval of MST minus MPFS. The relationship between MPFS and MST was modeled in a linear function. We used the coefficient of determination (r(2 to assess the correlation between them. Seventy trials with 145 chemotherapy arms were identified. Overall, median SPP was 4.7 months, and a steady improvement in SPP was observed over the 20 years (9.414-day increase per year; p<0.001 in parallel to the increase in MST (11.253-day increase per year; p<0.001; MPFS improved little (1.863-day increase per year. Overall, a stronger association was observed between MST and SPP (r(2 = 0.8917 than MST and MPFS time (r(2 = 0.2563, suggesting SPP and MPFS could account for 89% and 25% of the variation in MST, respectively. The association between MST and SPP became closer over the years (r(2 = 0.4428, 0.7242, and 0.9081 in 1988-1994, 1995-2001, and 2002-2007, respectively. CONCLUSIONS: SPP has become more closely associated with OS, potentially because of intensive post-study treatments. Even in advanced NSCLC, a PFS advantage is unlikely to be associated with an OS advantage any longer due to this increasing impact of SPP on OS, and that the prolongation of SPP might limit the original role of OS for assessing true efficacy derived from early-line chemotherapy in future clinical trials.

  4. The role of circulating anti-p53 antibodies in patients with advanced non-small cell lung cancer and their correlation to clinical parameters and survival

    International Nuclear Information System (INIS)

    Lung cancer causes approximately one million deaths each year worldwide and protein p53 has been shown to be involved in the intricate processes regulating response to radiation and/or chemotherapeutic treatment. Consequently, since antibodies against p53 (anti-p53 antibodies) are associated with mutations within the p53 gene it seems likely that these antibodies could, hypothetically, be correlated with prognosis. Serum samples from patients with non-small cell lung cancer (NSCLC) admitted to the Department of Oncology, University Hospital, Uppsala, Sweden, during 1983–1996 were studied. Anti-p53 abs were measured using a sandwich ELISA (Dianova, Hamburg, Germany). The present study included 84 patients with stage IIIA-IV (advanced NSCLC). At least three serum samples from each patient were collected and altogether 529 serum samples were analysed for the presence of anti-p53 antibodies. The median value of anti-p53 antibodies was 0.06 (range 0 – 139.8). Seventeen percent of investigated NSCLC first serum samples (n = 84) expressed elevated levels of anti-p53 antibodies. Anti-p53 antibodies were not correlated to tumour volume or platelets. Survival analysis showed that anti-p53 antibodies were not associated with survival as revealed by univariate analysis (p = 0.29). However, patients with adenocarcinoma had a significantly poorer survival if they expressed anti-p53 antibodies (p = 0.01), whereas this was not found for patients with squamous cell carcinoma (p = 0.13). In patients where the blood samples were collected during radiation therapy, a statistically significant correlation towards poorer survival was found (p = 0.05) when elevated anti-p53 antibodies levels were present. No correlations to survival were found for serum samples collected prior to radiation therapy, during chemotherapy, or during follow-up. When anti-p53 antibodies were measured continuously, no increase in median anti-p53 values was observed the closer the individual patient come to

    The immune system plays an important role in preventing and combating the growth of tumors. However, the tumor can escape immunosurveillance by exploiting a series of immune escape mechanisms that are developed to avoid autoimmunity. Among these mechanisms is the hijacking of immune checkpoints that are induced on T-cell activation. Immune checkpoint therapy, which targets regulatory pathways in T-cells to enhance antitumor immune responses, has led to important clinical advances and provided a new weapon against cancer. This therapy has elicited durable clinical responses and long-term survival, especially in a fraction of patients with advanced non-small cell lung cancer (NSCLC), and the activity seems relative to the expression status of tumor programmed cell death receptor ligand-1. Combinatorial approaches with other immune checkpoint inhibitors, chemotherapy, or targeting agents are being explored in ongoing clinical trials, which may improve the outcome in NSCLC.%免疫系统在预防和抵抗肿瘤生长中起着非常重要的作用。然而,肿瘤细胞会利用一系列本来是为了防止自身免疫的机制来避开免疫监视,如劫持与 T 细胞活化相关的免疫检查点等。目前,靶向 T 细胞调节通路上的免疫检查点以增强抗肿瘤免疫反应的治疗药物开发已经取得重要进展,并在临床治疗晚期非小细胞肺癌患者时导致出现了长期缓解例,疗效似与肿瘤细胞程序性死亡受体配体-1的表达相关。使用这类药物的联合治疗,包括与其他免疫检查点抑制剂、化疗药物和分子靶向药物等的联合治疗,现也在进行临床探索,有希望在将来改善非小细胞肺癌患者的预后。

    Full Text Available Background and objective Vinorelbine plus cisplatin/carboplatin (NP is one of the standard combination chemotherapy regimen for advanced non-small cell lung cancer (NSCLC. The aim of this study is toinvestigate the relationship between expression of Stathmin and β-tubulin-Ⅲ in NSCLC biopsies and sensitivity to Vinorelbine, which would provide a basis of the proper medicine choice for the patients' tailored chemotherapy. Methods Western blot was used to investigate the expression of Stathmin and β-tubulin-Ⅲ protein in the biopsies from stage ⅢB-Ⅳ NSCLC patients. All the cases were divided into 4 groups according to the level of the two proteins, of which L represented both protein expressed lowly, B showed β-tubulin-Ⅲ lowly expressed group, while S showed Stathmin lowly, and H represented both protein highly expressed. At the same time, all the patients accepted NP chemotherapy for 2 or 4 cycles according to the responses to this regimen. The responses rate (RR, media survival time (MST, time to progress (TTP were observed. Results A total of 90 stage ⅢB-Ⅳ NSCLC patients were divided into 4 groups, 22 in L group, 23 in B and S group while 22 in H group respectively. The RR of the groups were 68.2%, 26.1%, 30.4% and 22.7% respectively.There were statistically significant differences between L group and other 3 groups (P <0.05. The MST were 377, 305, 321 and 271 days respectively, and the TTP were 240, 182, 190 and 166 days in the 4 groups. Statistically significant differences between L group and other 3 groups (P <0.05 can be seen in both MST and TTP. Conclusion The expression of β-tubulin-Ⅲ and Stathmin in advanced NSCLC biopsies had relationship with the sensitivity to NP chemotherapyregimen in the patients. Cases with high level of these two proteins would have poor responses to this cytotoxic drug.

    Full Text Available Background and objective Due to the various inter-individual differences in the biological characteristics of tumor cells, as well as issues on the efficacy, adverse reactions, and defects of existing drugs, we compared the clinical efficacy and toxicity of pemetrexed and gemcitabine combined with cisplatin for the treatment of previously untreated advanced non-small cell lung cancer (NSCLC. Methods 251 patients were randomly divided into pemetrexed combined with cisplatin group (PP group with 127 cases and gemcitabine combined with cisplatin group (GP group with 124 cases. PP group received pemetrexed 500 mg/m2 iv infusion d1 and cisplatin 75 mg/m2 iv infusion d1, whereas GP group received gemcitabine 1,000 mg/m2 iv infusion d1,8 and cisplatin 75 mg/m2 iv infusion d1. The treatment cycle was once every three weeks. In addition, folic acid, vitamin B12, and dexamethasone were administered in both groups. Results The total clinical effective rates in PP group and GP group were 25.20% and 17.74%, respectively. The total efficiencies of non-squamous cell carcinoma were 27.62% and 16.00%. The tumor progression duration in these two groups was 6.5 and 5.6 months, respectively. The median survival time in the two groups was 16.9 and 17.0 months, respectively, with 59.62% and 65.87% survival rates of 1 year and 27.28% and 27.93% survival rates of 2 years, respectively. The total efficacy of non-squamous cell carcinoma in the PP group was significantly higher than that in GP group. The results were statistically significant. However, there were no significant differences in total response rates, tumor progression duration, and median survival rates of 1 and 2 years. The rate of adverse reactions, including white blood cell reduction, lower platelet count, lower hemoglobin, and hair loss in the PP group was significantly lower than that in the GP group. The results were statistically significant. Conclusion The clinical efficacy of pemetrexed and

    Full Text Available To observe the early change of metabolic tumor heterogeneity during chemoradiotherapy and to determine its prognostic value for patients with locally advanced non-small cell lung cancer (NSCLC.From January 2007 to March 2010, 58 patients with NSCLC were included who were received 18F-fluorodeoxyglucose (18F-FDG PET/CT before and following 40 Gy radiotherapy with the concurrent cisplatin-based chemotherapy (CCRT. Primary tumor FDG uptake heterogeneity was determined using global and local scale textural features extracted from standardized uptake value (SUV histogram analysis (coefficient of variation [COV], skewness, kurtosis, area under the curve of the cumulative SUV histogram [AUC-CSH] and normalized gray-level co-occurrence matrix (contrast, dissimilarity, entropy, homogeneity. SUVmax and metabolic tumor volume (MTV were also evaluated. Correlations were analyzed between parameters on baseline or during treatments with tumor response, progression-free survival (PFS, and overall survival (OS.Compared with non-responders, responders showed significantly greater pre-treatment COV, contrast and MTV (AUC = 0.781, 0.804, 0.686, respectively. Receiver-operating-characteristic curve analysis showed that early change of tumor textural analysis serves as a response predictor with higher sensitivity (73.2%~92.1% and specificity (80.0%~83.6% than baseline parameters. Change in AUC-CSH and dissimilarity during CCRT could also predict response with optimal cut-off values (33.0% and 28.7%, respectively. The patients with greater changes in contrast and AUC-CSH had significantly higher 5-year OS (P = 0.008, P = 0.034 and PFS (P = 0.007, P = 0.039. In multivariate analysis, only change in contrast was found as the independent prognostic factor of PFS (HR 0.476, P = 0.021 and OS (HR 0.519, P = 0.015.The metabolic tumor heterogeneity change during CCRT characterized by global and local scale textural features may be valuable for predicting treatment response

    Full Text Available Background and objective Erlotinib is a targeted therapy drug for non-small cell lung cancer (NSCLC. It has been proven that, there was evidence of various survival benefits derived from erlotinib in patients with different clinical features, but the results are conflicting. The aim of this study is to identify novel predictive factors and explore the interactions between clinical variables as well as their impact on the survival of Chinese patients with advanced NSCLC heavily treated with erlotinib. Methods The clinical and follow-up data of 105 Chinese NSCLC patients referred to the Cancer Hospital and Institute, Chinese Academy of Medical Sciences from September 2006 to September 2009 were analyzed. Multivariate analysis of progressive-free survival (PFS was performed using recursive partitioning referred to as the classification and regression tree (CART analysis. Results The median PFS of 105 eligible consecutive Chinese NSCLC patients was 5.0 months (95%CI: 2.9-7.1. CART analysis was performed for the initial, second, and third split in the lymph node involvement, the time of erlotinib administration, and smoking history. Four terminal subgroups were formed. The longer values for the median PFS were 11.0 months (95%CI: 8.9-13.1 for the subgroup with no lymph node metastasis and 10.0 months (95%CI: 7.9-12.1 for the subgroup with lymph node involvement, but not over the second-line erlotinib treatment with a smoking history ≤35 packs per year. The shorter values for the median PFS were 2.3 months (95%CI: 1.6-3.0 for the subgroup with lymph node metastasis and over the second-line erlotinib treatment, and 1.3 months (95%CI: 0.5-2.1 for the subgroup with lymph node metastasis, but not over the second-line erlotinib treatment with a smoking history >35 packs per year. Conclusion Lymph node metastasis, the time of erlotinib administration, and smoking history are closely correlated with the survival of advanced NSCLC patients with first- to

    Background Platinum-based regimens are used as standard first-line chemotherapy in non-small cell lung cancer (NSCLC) patients.To study if pharmacogenetic approach may allow a tailored selection of platinum chemotherapy for advanced NSCLC,we performed a meta-analysis to compare chemosensitivity to platinum with different ERCC1 C118T/MDR1 C3435T single-nucleotide polymorphism (SNP).Methods Relevant studies were identified by searching the PubMed,Embase,Cochrane,OVID,Springer,EBSCO and CNKI databases.Inclusion criteria were patients with advanced NSCLC who received platinum-based chemotherapy,an evaluated polymorphism of ERCC/MDR1 and overall response rate.We excluded duplicate publications,letters and review articles.The RevMan 4.2 and STATA 11 package were used to do comprehensive quantitative assessment.Results A total of 11 studies were included in this meta-analysis.For studies evaluating ERCC1 C118T,test for heterogeneity was done (x2=13.41,P=0.1),and the odds ratio (OR) for the wild-type C/C genotype versus the heterozygous C/T and T/T genotypes was 1.50 (95% CI 1.09-2.06,P=-0.01).In four studies evaluating MDR1 polymorphism,test for heterogeneity was also done (x2=3.22,P=0.36),and the OR for the wild-type C/C genotype versus the heterozygous C/T and T/T genotypes was 2.30 (95% CI 1.44-3.68,P=0.0005).Conclusions The results indicated that platinum-based chemotherapy sensitivity was significantly associated with polymorphism of ERCC1 C118T and MDR1 C3435T SNP.In further perspective studies,the ERCC1/MDR1 SNPs might serve as simple and less invasive biomarkers for personalized chemotherapy with platinum-based anticancer drugs.

    Full Text Available Background and objective Currently available studies on the polymorphisms of drug-metabolizing enzymes and their chemotherapeutic effects in non-small cell lung cancer are not consistent. In the present study, the relationship of the gene polymorphisms of cytochrome P450 1A1 (CYP1A1, cytochrome P450 2E1 (CYP2E1, cytochrome P450 2D6 (CYP2D6, and glutathione S-transferase M1 (GSTM1 enzymes with chemotherapeutic effects were investigated. The effects of these relationships on the survival of advanced non-small cell lung cancer patients were also examined. Methods Four drug metabolism enzymes were genotyped in lung cancer patients by polymerase chain reaction (PCR and PCR-restriction fragment length polymorphism. These patients were followed for five years. Results The chemotherapeutic effect on patients carrying B-type CYP1A1 and null-type GSTM1 was better than on those carrying other types (P<0.001. The chemotherapeutic effect on patients carrying A-type CYP1A1 was better than on those carrying the B and C types when non-platinum drugs were administered (P=0.041. The chemotherapeutic effect on patients carrying null-type GSTM1 was better than on those carrying the functional type when platinum drugs were administered (P=0.011. The four enzymes did not affect the overall survival (OS of advanced non-small cell lung cancer patients (P>0.05. Conclusion The chemotherapeutic effect on patients carrying A-type CYP1A1 was better than on those carrying the B and C types when non-platinum drugs were administered. The chemotherapeutic effect on patients carrying null-type GSTM1 was better than on those carrying the functional type when platinum drugs were administered.

    Full Text Available Motivation Until recently it was considered that 65 years is cutoff for defining patients as elderly, but newer reports indicate that this age limit shift to 70 years of age. Elderly patients with advanced non small cell lung cancer, associated comorbidities and poor performance status represent a specific population and a challenge for use of chemotherapy. Primary aim was to evaluate the impact of mono therapy with oral etoposide on overall survival in elderly patients (≥ 70 years of age with advanced non small cell lung cancer and poor performance status (PS ≥ 2 (clinical stage IIIb and IV , and as well to evaluate tolerability of this therapy. Secondary aim was to evaluate response rate.Methods Retrospectively, medical records of 79 female and male patients with advanced non small cell lung cancer and poor performance status treated with oral etoposide (2x25 mg 20 days/10 days pause in period from 2007 till 2010 were checked for relevant data. Data regarding demographics, performance status, overall survival, response rates and drug toxicity were collected. For statistical analysis we used Pearson chi-square test, T-test, Kaplan-Meier product limited method and Cox regression.Results Median overall survival (OS was 31 weeks, in patients with PS 2 overall survival was 34 weeks, and in group with PS 3 was only 24 weeks. Partial response was registered in 20.2% of patients, stable disease in 41.85 % and disease progression in 38% of patients. Treatment was well tolerated, febrile neutropenia and toxic deaths were not registered. Toxic effects didn't have statistically significant influence on OS.Conclusion Oral etoposide used as mono therapy has been shown as moderate effective and very safe in treating elderly patients with advanced non small cell lung cancer and poor performance status so it represents a good therapy option for treating this specific population.

    Purpose: Patients with advanced stage IIIB or stage IV non-small cell lung carcinoma are typically treated with initial platinum-based chemotherapy. A variety of factors (eg, performance status, gender, age, histology, weight loss, and smoking history) are generally accepted as predictors of overall survival. Because uncontrolled pulmonary disease constitutes a major cause of death in these patients, we hypothesized that clinical and radiographic factors related to intrathoracic disease at diagnosis may be prognostically significant in addition to conventional factors. The results have implications regarding the selection of patients for whom palliative thoracic radiation therapy may be of most benefit. Methods and Materials: We conducted a pooled analysis of 189 patients enrolled at a single institution into 9 prospective phase II and III clinical trials involving first-line, platinum-based chemotherapy. Baseline clinical and radiographic characteristics before trial enrollment were analyzed as possible predictors for subsequent overall survival. To assess the relationship between anatomic location and volume of disease within the thorax and its effect on survival, the pre-enrollment computed tomography images were also analyzed by contouring central and peripheral intrapulmonary disease. Results: On univariate survival analysis, multiple pulmonary-related factors were significantly associated with worse overall survival, including pulmonary symptoms at presentation (P=.0046), total volume of intrathoracic disease (P=.0006), and evidence of obstruction of major bronchi or vessels on prechemotherapy computed tomography (P<.0001). When partitioned into central and peripheral volumes, central (P<.0001) but not peripheral (P=.74) disease was associated with worse survival. On multivariate analysis with known factors, pulmonary symptoms (hazard ratio, 1.46; P=.042), central disease volume (hazard ratio, 1.47; P=.042), and bronchial/vascular compression (hazard ratio, 1

    Purpose: To analyze dosimetric variables and outcomes after adaptive replanning of radiation therapy during concurrent high-dose protons and chemotherapy for locally advanced non-small cell lung cancer (NSCLC). Methods and Materials: Nine of 44 patients with stage III NSCLC in a prospective phase II trial of concurrent paclitaxel/carboplatin with proton radiation [74 Gy(RBE) in 37 fractions] had modifications to their original treatment plans after re-evaluation revealed changes that would compromise coverage of the target volume or violate dose constraints; plans for the other 35 patients were not changed. We compared patients with adaptive plans with those with nonadaptive plans in terms of dosimetry and outcomes. Results: At a median follow-up of 21.2 months (median overall survival, 29.6 months), no differences were found in local, regional, or distant failure or overall survival between groups. Adaptive planning was used more often for large tumors that shrank to a greater extent (median, 107.1 cm{sup 3} adaptive and 86.4 cm{sup 3} nonadaptive; median changes in volume, 25.3% adaptive and 1.2% nonadaptive; P<.01). The median number of fractions delivered using adaptive planning was 13 (range, 4-22). Adaptive planning generally improved sparing of the esophagus (median absolute decrease in V{sub 70}, 1.8%; range, 0%-22.9%) and spinal cord (median absolute change in maximum dose, 3.7 Gy; range, 0-13.8 Gy). Without adaptive replanning, target coverage would have been compromised in 2 cases (57% and 82% coverage without adaptation vs 100% for both with adaptation); neither patient experienced local failure. Radiation-related grade 3 toxicity rates were similar between groups. Conclusions: Adaptive planning can reduce normal tissue doses and prevent target misses, particularly for patients with large tumors that shrink substantially during therapy. Adaptive plans seem to have acceptable toxicity and achieve similar local, regional, and distant control and overall

  1. Prognostic model for long-term survival of locally advanced non-small-cell lung cancer patients after neoadjuvant radiochemotherapy and resection integrating clinical and histopathologic factors

    International Nuclear Information System (INIS)

    Outcome of consecutive patients with locally advanced non-small cell lung cancer and histopathologically proven mediastional lymph node metastases treated with induction chemotherapy, neoadjuvant radiochemotherapy and thoracotomy at the West German Cancer Center between 08/2000 and 06/2012 was analysed. A clinico-pathological prognostic model for survival was built including partial or complete response according to computed tomography imaging (CT) as clinical parameters as well as pathologic complete remission (pCR) and mediastinal nodal clearance (MNC) as histopathologic factors. Proportional hazard analysis (PHA) and recursive partitioning analysis (RPA) were used to identify prognostic factors for survival. Long-term survival was defined as survival ≥ 36 months. A total of 157 patients were treated, median follow-up was 97 months. Among these patients, pCR and MNC were observed in 41 and 85 patients, respectively. Overall survival was 56 ± 4% and 36 ± 4% at 24 and 60 months, respectively. Sensitivities of pCR and MNC to detect long-term survivors were 38% and 61%, specificities were 84% and 52%, respectively. Multivariable survival analysis revealed pCR, cN3 category, and gender, as prognostic factors at a level of α < 0.05. Considering only preoperative available parameters, CT response became significant. Classifying patients with a predicted hazard above the median as high risk group and the remaining as low risk patients yielded better separation of the survival curves by the inclusion of histopathologic factors than by preoperative factors alone (p < 0.0001, log rank test). Using RPA, pCR was identified as the top prognostic factor above clinical factors (p = 0.0006). No long term survivors were observed in patients with cT3-4 cN3 tumors without pCR. pCR is the dominant histopathologic response parameter and improves prognostic classifiers, based on clinical parameters. The validated prognostic model can be used to estimate individual prognosis and

  3. Current situation of interventional treatment for non-small cell lung cancer

    International Nuclear Information System (INIS)

    Primary bronchogenic carcinoma, which referred to as lung cancer, is one of the most common malignant tumors in china. The 2010 China Health Statistical Yearbook indicates that in 2005 the mortality of lung cancer was at the first place of all cancers. Non-small-cell lung cancer (NSCLC) accounts for 8.5% of all the lung cancers, most of the patents are diagnosed in their late stages and have lost the chance of operation resection, and the 5-year survival rate is only about 15%. Being of technical simplicity, mild side reaction, satisfactory local effect and reliable reproducibility, interventional therapy has become an important and non-surgical method for advanced NSCLC, and has been widely applied in clinical practice. This paper aims to make a review about the current situation of interventional treatment for non-small cell lung cancer. (authors)

    Full Text Available Lung cancer is the leading cause of cancer-related mortality worldwide. Despiting the great progress on target agents, majority of people who do not harbor a mutation could not get benefit from them. Immunotherapy, through stimulating the body's immune system to improve the antitumor immunity effect, has been a new therapeutic method for non-small cell lung cancer (NSCLC. Study had been reported that immune checkpoint molecules, including programmed death-1 (PD-1/PD-ligand (L 1 axis, are closedly related with cancer generation and development, and play a key role on clinical significance of NSCLC. Activation of PD-1/PD-L1 pathway contributes to tumor immune escape, and block PD-1/PD-L1 pathway can enhance endogenous antimuor immunity. Currently increasing clinical trials suggested that immune checkpoint inhibitors, including anti-PD-1 and anti-PD-L1 monoclonal antibodies turned out to be beneficial and safe in NSCLC. Here, we provide a review on the progress of PD-1/PD-L1 pathway and immune checkpoint inhibitors in NSCLC.

    Full Text Available Since efficacy and safety of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs versus chemotherapy in the treatment of patients with pretreated advanced non-small cell lung cancer (NSCLC remain controversial, we performed a meta-analysis to compare them.An internet search of several databases was performed, including PubMed, Embase, and the Cochrane database. Randomized trials that compared an EGFR-TKI with chemotherapy in the second-line setting were included. The outcomes were progression-free survival (PFS, overall survival (OS, objective response rate (ORR, and grade 3-4 toxicities. The PFS, OS for the EGFR mutation-positive (EGFR M+ and EGFR mutation-negative (EGFR M- subgroups were pooled. The pooled hazard ratios (HRs and odds ratios (ORs with their corresponding confidence intervals (CIs were calculated on the STATA software.Our meta-analysis combined 3,825 patients from 10 randomized trials. Overall, EGFR-TKIs and second-line chemotherapy have equivalent efficacy in terms of PFS (HR, 1.03; 95%CI, 0.87-1.21; P = 0.73; I2 = 78.7%, Pheterogeneity<0.001, OS (HR, 1.00; 95%CI, 0.92-1.08; P = 0.90; I2 = 0.0%, Pheterogeneity = 0.88, and ORR (OR, 1.34; 95%CI, 0.86-2.08; P = 0.20; I2 = 73.1%, Pheterogeneity<0.001. However, subgroup analysis based on EGFR mutation status showed that second-line chemotherapy significantly improved PFS (HR, 1.35; 95%CI, 1.09-1.66; P = 0.01; I2 = 55.7%, Pheterogeneity = 0.046 for EGFR M- patients, whereas OS was equal (HR, 0.96; 95%CI, 0.77-1.19; P = 0.69; I2 = 0.0%, Pheterogeneity = 0.43; EGFR-TKIs significantly improved PFS (HR, 0.28; 95%CI, 0.15-0.53; P<0.001; I2 = 4.1%, Pheterogeneity = 0.35 for EGFR M+ patients, whereas OS was equal (HR, 0.86; 95%CI, 0.44-1.68; P = 0.65; I2 = 0.0%, Pheterogeneity = 0.77. Compared with chemotherapy, EGFR-TKIs led to more grade 3-4 rash, but less fatigue/asthenia disorder, leukopenia and

    International audience Non-small cell lung cancers present a 5-year survival rate below 12%. Such a poor prognosis may be explained by non small cell lung cancer cells evasion to apoptosis and resistance to treatments. Amphiregulin, an epidermal growth factor-related growth factor is secreted by non-small cell lung cancer cells in an autocrine/paracrine manner to promote autonomous growth of tumor cells and to provide resistance to apoptosis. Furthermore, amphiregulin is involved in non-sm...

  10. Clinically Meaningful Differences in Patient-Reported Outcomes With Amifostine in Combination With Chemoradiation for Locally Advanced Non-Small-Cell Lung Cancer: An Analysis of RTOG 9801

    International Nuclear Information System (INIS)

    Purpose: The purpose of this study is to analyze changes in quality of life (QOL) and symptoms from pretreatment to 6 weeks posttreatment in a Phase III randomized study (Radiation Therapy Oncology Group 9801) of amifostine (AM) vs. no AM in patients with Stages II-III non-small-cell lung cancer receiving paclitaxel and carboplatin as induction and then concurrently with hyperfractionated radiation therapy (RT). Methods and Materials: One hundred thirty-eight patients with baseline and 6-week posttreatment QOL data were analyzed. There were no significant differences in baseline demographics between those who did and did not have QOL data. The QOL and symptoms were assessed by using the European Organization for Research and Treatment of Cancer (EORTC) Global QOL and Pain subscales and the EORTC-Lung Cancer-13 symptom tool. Clinically relevant changes in QOL were characterized by 10-point differences in individual scores pre/post treatment. A daily diary of patient-rated difficulty swallowing and a weekly physician-rated dysphagia log (using National Cancer Institute Common Toxicity Criteria) were completed during treatment. Weight loss was monitored. Differences in outcomes were examined according to smoking status, alcohol use, and sex. Results: Patients receiving AM reported significantly greater pain reduction after chemoradiation (34% vs. no AM, 21%), less difficulty swallowing during chemoradiation, and less weight loss than patients not receiving AM. However, physician-rated assessments of dysphagia were not significantly different by treatment arm. There were no other significant changes in QOL or symptoms according to treatment arm, smoking status, alcohol use, or sex. Conclusions: Patient evaluations of difficulty swallowing and pain suggest benefits from AM use that are distinct from clinician-rated assessments

    Zeng, Xiaoning; Ma, Yuan

    2016-01-01

    Background The benefit of maintenance therapy has been confirmed in patients with non-progressing non-small cell lung cancer (NSCLC) after first-line therapy by many trials and meta-analyses. However, since few head-to-head trials between different regimens have been reported, clinicians still have little guidance on how to select the most efficacious single-agent regimen. Hence, we present a network meta-analysis to assess the comparative treatment efficacy of several single-agent maintenance therapy regimens for stage III/IV NSCLC. Methods A comprehensive literature search of public databases and conference proceedings was performed. Randomized clinical trials (RCTs) meeting the eligible criteria were integrated into a Bayesian network meta-analysis. The primary outcome was overall survival (OS) and the secondary outcome was progression free survival (PFS). Results A total of 26 trials covering 7,839 patients were identified, of which 24 trials were included in the OS analysis, while 23 trials were included in the PFS analysis. Switch-racotumomab-alum vaccine and switch-pemetrexed were identified as the most efficacious regimens based on OS (HR, 0.64; 95% CrI, 0.45–0.92) and PFS (HR, 0.54; 95% CrI, 0.26–1.04) separately. According to the rank order based on OS, switch-racotumomab-alum vaccine had the highest probability as the most effective regimen (52%), while switch-pemetrexed ranked first (34%) based on PFS. Conclusions Several single-agent maintenance therapy regimens can prolong OS and PFS for stage III/IV NSCLC. Switch-racotumomab-alum vaccine maintenance therapy may be the most optimal regimen, but should be confirmed by additional evidence.

  15. Role of [18F]FDG PET in prediction of KRAS and EGFR mutation status in patients with advanced non-small-cell lung cancer

    International Nuclear Information System (INIS)

    The tumour molecular profile predicts the activity of epidermal growth factor receptor (EGFR) inhibitors in non-small-cell lung cancer (NSCLC). However, tissue availability and tumour heterogeneity limit its assessment. We evaluated whether [18F]FDG PET might help predict KRAS and EFGR mutation status in NSCLC. Between January 2005 and October 2011, 340 NSCLC patients were tested for KRAS and EGFR mutation status. We identified patients with stage III and IV disease who had undergone [18F]FDG PET/CT scanning for initial staging. SUVpeak, SUVmax and SUVmean of the single hottest tumour lesions were calculated, and their association with KRAS and EGFR mutation status was assessed. A receiver operator characteristic (ROC) curve analysis and a multivariate analysis (including SUVmean, gender, age and AJCC stage) were performed to identify the potential value of [18F]FDG PET/CT for predicting KRAS mutation. From 102 patients staged using [18F]FDG PET/CT, 28 (27 %) had KRAS mutation (KRAS+), 22 (22 %) had EGFR mutation (EGFR+) and 52 (51 %) had wild-type KRAS and EGFR profiles (WT). KRAS+ patients showed significantly higher [18F]FDG uptake than EGFR+ and WT patients (SUVmean 9.5, 5.7 and 6.6, respectively; p 18F]FDG uptake between EGFR+ patients and WT patients. ROC curve analysis for KRAS mutation status discrimination yielded an area under the curve of 0.740 for SUVmean (p 18F]FDG uptake than WT patients, as assessed in terms of SUVpeak, SUVmax and SUVmean. A multivariate model based on age, gender, AJCC stage and SUVmean might be used as a predictive marker of KRAS mutation status in patients with stage III or IV NSCLC. (orig.)

  16. Induction Chemotherapy and Continuous Hyperfractionated Accelerated Radiotherapy (CHART) for Patients With Locally Advanced Inoperable Non-Small-Cell Lung Cancer: The MRC INCH Randomized Trial

    International Nuclear Information System (INIS)

    Purpose: Recent clinical trials and meta-analyses have shown that both CHART (continuous hyperfractionated accelerated radiation therapy) and induction chemotherapy offer a survival advantage over conventional radical radiotherapy for patients with inoperable non-small cell-lung cancer (NSCLC). This multicenter randomized controlled trial (INCH) was set up to assess the value of giving induction chemotherapy before CHART. Methods and Materials: Patients with histologically confirmed, inoperable, Stage I-III NSCLC were randomized to induction chemotherapy (ICT) (three cycles of cisplatin-based chemotherapy followed by CHART) or CHART alone. Results: Forty-six patients were randomized (23 in each treatment arm) from 9 UK centers. As a result of poor accrual, the trial was closed in December 2007. Twenty-eight patients were male, 28 had squamous cell histology, 34 were Stage IIIA or IIIB, and all baseline characteristics were well balanced between the two treatment arms. Seventeen (74%) of the 23 ICT patients completed the three cycles of chemotherapy. All 42 (22 CHART + 20 ICT) patients who received CHART completed the prescribed treatment. Median survival was 17 months in the CHART arm and 25 months in the ICT arm (hazard ratio of 0.60 [95% CI 0.31-1.16], p = 0.127). Grade 3 or 4 adverse events (mainly fatigue, dysphagia, breathlessness, and anorexia) were reported for 13 (57%) CHART and 13 (65%) ICT patients. Conclusions: This small randomized trial indicates that ICT followed by CHART is feasible and well tolerated. Despite closing early because of poor accrual, and so failing to show clear evidence of a survival benefit for the additional chemotherapy, the results suggest that CHART, and ICT before CHART, remain important options for the treatment of inoperable NSCLC and deserve further study.

    Full Text Available Background and objective Controversy exists on whether amifostine can reduce the efficacy and decrease the side effects of non-small cell lung cancer (NSCLC treated by radiotherapy. The aim of this meta-analysis is to evaluate the efficacy and side effects of amifostine in NSCLC patients treated with radiotherapy. Methods Open published randomized controlled trials on the efficacy and side effects of amifostine in NSCLC patients treated with radiotherapy were collected from Medline, Cochrane Central Register of Controlled Trials, EMBSE, CBM, CNKI, WANFANG, American Society of Clinical Oncology, and European Society of Medical Oncology databases. The pooled efficacy and side effects of amifostine in these patients were calculated using the statistics software Stata 11.0. Results Nine trials that included 769 (381 and 388 in each arm patients were analyzed. The pooled relative risk of complete, partial, and objective responses were 1.16 (95%CI: 0.90-1.50, Z=1.07, P=0.29, 1.02 (95%CI: 0.87-1.19, Z=0.21, P=0.83 and 1.06 (95%CI: 0.97-1.17, Z=1.31, P=0.20, respectively. The side effects in seven trials including 738 (367 and 371 in each arm patients were analyzed. The pooled relative risk of developing grades 3 to 4 esophagitis and pneumonitis were 0.51 (95%CI: 0.37-0.72, Z=3.88, P<0.001 and 0.51 (95%CI: 0.26-0.99, Z=1.98, P=0.04, respectively. Conclusion Amifostine can significantly decrease the risk of developing serious esophagitis and pneumonitis without reducing the response rate in NSCLC patients treated by radiotherapy.

    Full Text Available Background. This study tested the hypothesis that circulating microparticles (MPs are useful biomarkers for predicting one-year mortality in patients with end-stage non-small cell lung cancer (ES-NSCLC. Methods and Results. One hundred seven patients were prospectively enrolled into the study between April 2011 and February 2012, and each patient received regular follow-up after enrollment. Levels of four MPs in circulation, (1 platelet-derived activated MPs (PDAc-MPs, (2 platelet-derived apoptotic MPs (PDAp-MPs, (3 endothelial-derived activated MPs (EDAc-MPs, and (4 endothelial-derived apoptotic MPs (EDAp-MPs, were measured just after the patient was enrolled into the study using flow cytometry. Patients who survived for more than one year were categorized into group 1 (n=56 (one-year survivors and patients who survived less than one year were categorized into group 2 (n=51 (one-year nonsurvivors. Male gender, incidence of liver metastasis, progression of disease after first-line treatment, poor performance status, and the Charlson comorbidity index were significantly higher in group 2 than in group 1 (all P<0.05. Additionally, as measured by flow cytometry, only the circulating level of EDAc-MPs was found to be significantly higher in group 2 than in group 1 (P=0.006. Multivariate analysis demonstrated that circulating level of EDAc-MPs along with brain metastasis and male gender significantly and independently predictive of one-year mortality (all P<0.035. Conclusion. Circulating EDAc-MPs may be a useful biomarker predictive of one-year morality in ES-NSCLC patients.

    Full Text Available Purpose: Preclinical findings suggest that adding targeted therapies to combination radiation-chemotherapy can enhance treatment efficacy; however, this approach may enhance normal tissue toxicity. We investigated the maximum tolerated dose, dose-limiting toxicities, and response rate when the selective cyclo-oxygenase-2 inhibitor celecoxib is added to concurrent irinotecan, cisplatin, and radiation therapy for patients with inoperable stage II-III non-small cell lung cancer. Methods and materials: Eighteen patients were analyzed in a phase I clinical dose-escalation trial. Celecoxib was given daily beginning 5 days before radiation followed by maintenance doses for 12 weeks. Toxicity was graded with the Common Terminology Criteria for Adverse Events V3.0 and response with the World Health Organization system. Primary endpoints were maximum tolerated dose of celecoxib and treatment toxicity; secondary endpoints were response and survival rates. Results: The maximum tolerated dose of celecoxib was not reached, in part owing to discontinuation of the drug supply. At doses of 200 or 400 mg/day, no patients experienced any dose-limiting toxicity (acute grade ≥4 esophagitis or pneumonitis, neutropenic fever or thrombocytopenia requiring transfusion, or acute grade ≥3 diarrhea. Grade 3 toxicities were leukopenia (5 patients, fatigue (3, pneumonitis (2, dyspnea (1, pain (1, and esophageal stricture (1. Interestingly, pulmonary fibrosis (a late toxicity was no more severe in the higher-dose (400-mg group and may have been less common than in the lower-dose group. The clinical response rate was 100% (8 complete, 10 partial. Two-year rates were: overall survival 65%; local-regional control 69%; distant metastasis-free survival 71%; and disease-free survival 64%. Conclusions: Although preliminary, our results suggest that adding celecoxib to concurrent chemoradiation for inoperable NSCLC is safe and can improve outcome without increasing normal tissue

    2012-03-01

    Purpose: Our institutional experience with the use of hyperfractionated radiation therapy (RT) alone or concurrently with chemotherapy (RT-CHT) in Stage III non-small-cell lung cancer was reviewed. Methods and Materials: Three phase III and two phase II studies included a total of 600 patients. Hyperfractionated RT alone was given to 127 patients, and hyperfractionated RT-CHT was given to 473 patients. RT doses were 64.8 Gy and 69.6 Gy (using 1.2 Gy twice daily) and 67.6 Gy (using 1.3 Gy twice daily). CHT consisted of concurrent administration of carboplatin and etoposide to 409 patients and concurrent administration of carboplatin and paclitaxel to 64 patients. Results: The median survival times were 19 months, 21 months, and 12 months for all, RT-CHT, and RT-only patients, respectively. The survival difference between the RT-CHT and RT group was significant (p < 0.0001). Four-year rates of local progression-free survival (LPFS) and distant metastasis-free survival (DMFS) were 29% and 35%, respectively, for the entire group. The RT-CHT group had significantly better LPFS rates than the RT group (31% for the RT-CHT group vs. 16% for the RT group; p = 0.0015) but not DMFS rates (36% for the RT-CHT group vs. 36% for the RT group, p = 0.0571). Acute high-grade esophagitis, pneumonitis, and hematological toxicities were seen most frequently and in 11%, 9%, and 12% of patients, respectively. Late high-grade esophageal and bronchopulmonary toxicity were each seen in 6% of patients. Conclusions: Compared to the majority of existing phase II and III studies, this study reconfirmed the excellent results achieved with concurrent RT-CHT, including low toxicity. Concurrent RT-CHT results in survival benefit primarily by increasing LPFS, not DMFS.

    One hundred ninety-two patients with previously untreated metastatic cancer (102 non-small-cell lung cancer [NSCLC]; 90 colorectal cancer) were randomized to receive either ad lib nutritional intake (control group) or specific nutritional intervention during a 12-week study period when chemotherapy was administered. Those patients randomized to nutritional interventions were counselled to take oral nutrients with caloric intake equal to 1.7 to 1.95 times their basal energy expenditure, depending on their pretreatment nutritional status ("standard" group). An augmented group was counselled to have a caloric intake equivalent to that of the standard group but with 25% of calories provided as protein and additional supplements of zinc and magnesium. Counselling increased caloric intake in both tumor types but reduced weight loss in the short term only for lung cancer patients. Ninety-three NSCLC patients were evaluable for tumor response to vindesine and cisplatin. Overall, only 20.4% of the patients responded, and there were no significant differences in response rates, median time to progression, or overall duration of survival between the nutrition intervention groups and the control group. The tumor response rate to time-sequenced 5-fluorouracil (5-FU) and methotrexate in the 81 evaluable patients with colorectal cancer was only 14.8%, and no significant differences in tumor response rates were noted between the three groups. Furthermore, the median time to progression and overall duration of survival were not different for the control, standard, and augmented groups. Nutritional interventions using dietary counselling had no impact on the percent of planned chemotherapy dose administered, the degree of toxicity experienced by patients, or the frequency of treatment delays. A multivariate prognostic factor analysis demonstrated that for lung cancer, the percent of weight loss, serum albumin concentration, and presence of liver metastases were significant (P less

    2014-01-01

    Wnt/β-catenin alterations are prominent in human malignancies. In non-small cell lung cancer (NSCLC), β-catenin and APC mutations are uncommon, but Wnt signaling is important in NSCLC cell lines, and Wnt inhibition reduces proliferation. Overexpression of Wnt-1, -2, -3, and -5a and of Wnt-pathway components Frizzled-8, Dishevelled, Porcupine, and TCF-4 is common in resected NSCLC and is associated with poor prognosis. Conversely, noncanonical Wnt-7a suppresses NSCLC development and is often downregulated. Although β-catenin is often expressed in NSCLCs, it was paradoxically associated with improved prognosis in some series, possibly because of E-cadherin interactions. Downregulation of Wnt inhibitors (eg, by hypermethylation) is common in NSCLC tumor cell lines and resected samples; may be associated with high stage, dedifferentiation, and poor prognosis; and has been reported for AXIN, sFRPs 1-5, WIF-1, Dkk-1, Dkk-3, HDPR1, RUNX3, APC, CDX2, DACT2, TMEM88, Chibby, NKD1, EMX2, ING4, and miR-487b. AXIN is also destabilized by tankyrases, and GSK3β may be inactivated through phosphorylation by EGFR. Preclinically, restoration of Wnt inhibitor function is associated with reduced Wnt signaling, decreased cell proliferation, and increased apoptosis. Wnt signaling may also augment resistance to cisplatin, docetaxel, and radiotherapy, and Wnt inhibitors may restore sensitivity. Overall, available data indicate that Wnt signaling substantially impacts NSCLC tumorigenesis, prognosis, and resistance to therapy, with loss of Wnt signaling inhibitors by promoter hypermethylation or other mechanisms appearing to be particularly important. Wnt pathway antagonists warrant exploration clinically in NSCLC. Agents blocking selected specific β-catenin interactions and approaches to increase expression of downregulated Wnt inhibitors may be of particular interest. PMID:24309006

  5. Effect of EGFR-TKI retreatment following chemotherapy for advanced non-small cell lung cancer patients who underwent EGFR-TKI

    International Nuclear Information System (INIS)

    Non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR)-activating mutations have higher response rate and more prolonged survival following treatment with single-agent EGFR tyrosine kinase inhibitor (EGFR-TKI) compared with patients with wild-type EGFR. However, all patients treated with reversible inhibitors develop acquired resistance over time. The mechanisms of resistance are complicated. The lack of established therapeutic options for patients after a failed EGFR-TKI treatment poses a great challenge to physicians in managing this group of lung cancer patients. This study evaluates the influence of EGFR-TKI retreatment following chemotherapy after failure of initial EGFR-TKI within at least 6 months on NSCLC patients. The data of 27 patients who experienced treatment failure from their initial use of EGFR-TKI within at least 6 months were analyzed. After chemotherapy, the patients were retreated with EGFR-TKI (gefitinib 250 mg qd or erlotinib 150 mg qd), and the tumor progression was observed. The patients were assessed for adverse events and response to therapy. Targeted tumor lesions were assessed with CT scan. Of the 27 patients who received EGFR-TKI retreatment, 1 (3.7%) patient was observed in complete response (CR), 8 (29.6%) patients in partial response (PR), 14 (51.9%) patients in stable disease (SD), and 4 (14.8%) patients in progressive disease (PD). The disease control rate (DCR) was 85.2% (95% CI: 62%-94%). The median progression-free survival (mPFS) was 6 months (95% CI: 1-29). Of the 13 patients who received the same EGFR-TKI, 1 patient in CR, 3 patients in PR, 8 patients in SD, and 2 patients in PD were observed. The DCR was 84.6%, and the mPFS was 5 months. Of the 14 patients who received another EGFR-TKI, no patient in CR, 6 patients in PR, 6 patients in SD, and 2 patients in PD were observed. The DCR was 85.7%, and the mPFS was 9.5 months. Significant difference was found between the two groups in PFS but not

    A 53-year-old female patient was admitted with pain and a progressively enlarging mass in the right upper chest. Chest computed tomography revealed a mass lesion in the region of the right upper ribs. Ten years prior to this admission, the patient had undergone right lobectomy for lung adenocarcinoma. One year after the surgery, follow-up computed tomography had revealed tumor recurrence in the mediastinal and supraclavicular lymph nodes, and the patient had been treated by chemoradiotherapy. Thereafter, regular follow-up had revealed no evidence of recurrence of the non-small-cell lung cancer. Histopathological findings revealed proliferation of spindle-shaped malignant tumor cells in a background of osteoid, consistent with the diagnosis of osteosarcoma. The location of the tumor was consistent with the radiation field. Based on the clinicopathological findings, the patient was diagnosed as having secondary osteosarcoma occurring as a result of the chemoradiotherapy administered previously for the recurrent non-small-cell lung cancer. Unfortunately, the patient died of rapid progression of the osteosarcoma within a week of admission to the hospital. The autopsy revealed contiguous invasion by the tumor of the heart, with massive thrombus formation. The peripheral pulmonary arteries were diffusely occluded by metastatic tumors. Our case serves to highlight the risk of development of secondary sarcoma as a life-threatening late complication after chemoradiotherapy for locally advanced non-small-cell lung cancer, even after complete cure of the primary tumor.

    Full Text Available OBJECTIVES: It has been recognized that patients with non-small cell lung cancer who are lifelong never-smokers constitute a distinct clinical entity. The aim of this study was to assess clinical risk factors for survival among neversmokers with non-small cell lung cancer. METHODS: All consecutive non-small cell lung cancer patients diagnosed (n = 285 between May 2005 and May 2009 were included. The clinical characteristics of never-smokers and ever-smokers (former and current were compared using chi-squared or Student's t tests. Survival curves were calculated using the Kaplan-Meier method, and log-rank tests were used for survival comparisons. A Cox proportional hazards regression analysis was evaluated by adjusting for age (continuous variable, gender (female vs. male, smoking status (never- vs. ever-smoker, the Karnofsky Performance Status Scale (continuous variable, histological type (adenocarcinoma vs. non-adenocarcinoma, AJCC staging (early vs. advanced staging, and treatment (chemotherapy and/or radiotherapy vs. the best treatment support. RESULTS: Of the 285 non-small cell lung cancer patients, 56 patients were never-smokers. Univariate analyses indicated that the never-smoker patients were more likely to be female (68% vs. 32% and have adenocarcinoma (70% vs. 51%. Overall median survival was 15.7 months (95% CI: 13.2 to 18.2. The never-smoker patients had a better survival rate than their counterpart, the ever-smokers. Never-smoker status, higher Karnofsky Performance Status, early staging, and treatment were independent and favorable prognostic factors for survival after adjusting for age, gender, and adenocarcinoma in multivariate analysis. CONCLUSIONS: Epidemiological differences exist between never- and ever-smokers with lung cancer. Overall survival among never-smokers was found to be higher and independent of gender and histological type.

    Anaplastic lymphoma kinase (ALK) gene fusions occur in 3%-7% of non-small-cell lung cancer (NSCLC) cases. Ceritinib, a once-daily, oral ALK inhibitor, has activity against crizotinib-resistant and crizotinib-naïve NSCLC, including brain metastases. Ceritinib (Zykadia™) was granted accelerated approval by the US Food and Drug Administration in 2014 for treating crizotinib-resistant ALK-positive NSCLC. Adverse events (AEs), particularly gastrointestinal (GI) AEs, are commonly experienced at the recommended dose of 750 mg/d and ∼38% of patients require dose interruption or reduction for GI AEs. This case study details our experience with the use of proactive GI AE management regimens in patients treated with ceritinib (750 mg/d) across two study sites. Proactive Regimens A and B were implemented in patients with metastatic ALK-positive NSCLC treated with ceritinib to manage drug-related GI AEs. Regimen A comprised ondansetron and diphenoxylate/atropine or loperamide, taken 30 minutes prior to ceritinib dose. Regimen B included dicyclomine (taken with the first ceritinib dose), ondansetron (taken 30 minutes prior to ceritinib dose for the first seven doses), and loperamide (taken as needed with the onset of diarrhea). The proactive medications were tapered off depending on patient tolerability to ceritinib. Nine patient cases are presented. Starting Regimens A or B before the first dose of ceritinib, or as soon as GI symptoms were encountered, prevented the need for dose reduction due to GI toxicity in eight of the nine patients. Using these regimens, 78% of patients were able to remain on 750 mg/d fasting. Two patients received 23 months and 16 months of therapy and remain on ceritinib 750 mg/d and 600 mg/d, respectively. Although not currently recommended or implemented in clinical studies, based on the patients evaluated here, upfront or proactive treatment plans that address AEs early on can allow the majority of patients to remain on the approved 750 mg

    The tumour molecular profile predicts the activity of epidermal growth factor receptor (EGFR) inhibitors in non-small-cell lung cancer (NSCLC). However, tissue availability and tumour heterogeneity limit its assessment. We evaluated whether [{sup 18}F]FDG PET might help predict KRAS and EFGR mutation status in NSCLC. Between January 2005 and October 2011, 340 NSCLC patients were tested for KRAS and EGFR mutation status. We identified patients with stage III and IV disease who had undergone [{sup 18}F]FDG PET/CT scanning for initial staging. SUVpeak, SUVmax and SUVmean of the single hottest tumour lesions were calculated, and their association with KRAS and EGFR mutation status was assessed. A receiver operator characteristic (ROC) curve analysis and a multivariate analysis (including SUVmean, gender, age and AJCC stage) were performed to identify the potential value of [{sup 18}F]FDG PET/CT for predicting KRAS mutation. From 102 patients staged using [{sup 18}F]FDG PET/CT, 28 (27 %) had KRAS mutation (KRAS+), 22 (22 %) had EGFR mutation (EGFR+) and 52 (51 %) had wild-type KRAS and EGFR profiles (WT). KRAS+ patients showed significantly higher [{sup 18}F]FDG uptake than EGFR+ and WT patients (SUVmean 9.5, 5.7 and 6.6, respectively; p < 0.001). No significant differences were observed in [{sup 18}F]FDG uptake between EGFR+ patients and WT patients. ROC curve analysis for KRAS mutation status discrimination yielded an area under the curve of 0.740 for SUVmean (p < 0.001). The multivariate analysis showed a sensitivity and specificity of 78.6 % and 62.2 %, respectively, and the AUC was 0.773. NSCLC patients with tumours harbouring KRAS mutations showed significantly higher [{sup 18}F]FDG uptake than WT patients, as assessed in terms of SUVpeak, SUVmax and SUVmean. A multivariate model based on age, gender, AJCC stage and SUVmean might be used as a predictive marker of KRAS mutation status in patients with stage III or IV NSCLC. (orig.)

  7. Overcoming toxicity-challenges in chemoradiation for non-small cell lung cancer

    Science.gov (United States)

    2016-01-01

    Concurrent chemoradiation (CCRT) is the treatment of choice for locally advanced non-small cell lung cancer (NSCLC) with a modest survival benefit over sequential chemoradiation or radiotherapy (SCRT) alone. However, this benefit is at the cost of increasing acute toxicity such as esophagitis. Previous analysis revealed several predictive parameters in dose-volume and patient characteristics which helped us to identify those patients at risk for severe esophagus toxicity. As a result, supportive care interventions including individualized patient information, dietary guidance, adequate medication, hydration and tubefeeding could be initiated. This paper discusses the challenges in overcoming chemoradiation induced acute esophageal toxicity (AET).

  8. Concurrent chemoradiation for stage III non small cell lung cancer: present results and future prospects

    International Nuclear Information System (INIS)

    The prognosis of stage III non small cell lung cancer is reportedly poor, particularly in patients with mediastinal lymph node involvement. These patients may be either good surgical candidates, marginally resectable, or inoperable for technical or medical reasons, but, in any case, surgery and/or radiotherapy are curative in only a minority of them. The high incidence of early distant failures underscores the need for early and effective systemic therapy in association with local treatment, since occult metastatic disease is present in most patients at the time of diagnosis. Recent phase III trials have demonstrated significant benefit to induction chemotherapy prior to irradiation or surgery in reducing the distant metastasis rate. However, poor local control remains a major issue in these locally advanced tumors. In patients with inoperable disease, the concomitant use of chemotherapy along with radiotherapy substantially improves local control. For operable patients, induction chemotherapy with concomitant moderate-dose radiotherapy improves local control as well, and may facilitate surgical resection in marginally operable cases. Currently, a number of phase II clinical trials report encouraging results with concomitant chemoradiotherapy used either prior to surgery or with curative intent in locally advanced non small cell lung cancer.

    This study was performed to investigate if the microRNA-related single-nucleotide polymorphisms (miR-SNPs) of XPO5 gene predicted the prognosis and pathological features of advanced non-small-cell lung cancer patients receiving chemotherapy. A total of 131 advanced non-small-cell lung cancer (NSCLC) patients were recruited. MicroRNA (miRNA) binding site prediction software was adopted for the prediction and screening of SNPs in XPO5 and miRNA binding regions. Polymerase chain reaction (PCR) amplification was further performed. Time-dependent survival-free curves were constructed using the Kaplan-Meier technique. Univariate and the multivariate survival analyses were conducted for confirmation of prognostic factor for advanced NSCLC patients receiving chemotherapy. There were no significant differences of SNP distribution frequencies between groups, without statistical significance (P > 0.05). Included clinical pathological features and chemotherapy regimens showed no apparent statistical significance in influencing the curative effect of chemotherapy in advanced NSCLC patients (all P > 0.05). While the objective response rate (ORR) in patients who carried AA and AC genotype was 35.48 and 51.22 %, respectively, with statistically significant difference (P < 0.05). Univariate survival analysis indicated that patients who carried AA genotype showed a significantly lower 5-year survival rate to those who carried AC genotype (P < 0.05). And, considering pathological features, statistical significance was found in patients with different pathological types, lymph node metastasis, differentiation degree, T staging, and pathological staging (all P < 0.05). Multivariate analysis results indicated that the SNP sites of rs11077 might be an independent prognostic factor of advanced NSCLC patients receiving chemotherapy (risk ratio [RR] = 0.346; 95 % confidence interval [95 % CI] = 0.174-0.685, P = 0.002).

    Full Text Available Surgery plays a major role in the management of patients with lung cancer. Surgery is not only the main curative treatment modality in patients with early-stage lung cancer but it also has a significant role in the initial workup for the diagnosis and staging of lung cancer. This article describes the surgical management of patients with lung cancer. Surgical resection for lung cancer is still regarded as the most effective method for controlling the primary tumor, provided it is resectable for cure and the risks of the procedure are low. The 5-year survival rare following complete resection (R0 of a lung cancer is stage dependent [Table 1]. [1-3] Incomplete resection (R1, R2 rarely, if ever, cures the patient.

    Non-small-cell carcinomas of the lung, especially adenocarcinomas, are characterized by a high degree of morphological heterogeneity. As carcinogenesis has been suggested to be a multistep process involving sequential accumulation of multiple genetic alterations, morphological heterogeneity may represent a cross-sectional view of genetic alterations within individual tumors. We therefore examined the topographical distribution of loss of heterozygosity (LOH) events within 10 non-small-cell lu...

    肺癌是全球最常见的恶性肿瘤之一,严重威胁人类生命。近年来,以表皮生长因子受体酪氨酸激酶抑制剂(epidermal growth factor receptor tyrosine kinase inhibitors, EGFR-TKIs)为首的靶向药物在肺癌治疗中取得巨大进展。因其具有高选择性和低毒性的优势,目前已成为IV期非小细胞肺癌(non-small cell lung cancer, NSCLC)EGFR突变患者的一线治疗方案。然而随着临床的广泛应用,继发耐药成为临床亟待解决的问题。近年来,基础研究证实, EGFR-TKI具有放射增敏性,理论上二者联合不但可以解决放疗后期肿瘤的放射抵抗以及EGFR-TKI继发耐药,还可以增加对肿瘤杀伤能力,同时副反应较同步放化疗小。因此,EGFR-TKI与放疗联合成为晚期NSCLC(IIIb期/IV期)极具探索的治疗模式。本文就EGFR-TKI与放疗联合治疗晚期NSCLC的基础与临床研究进展进行综述。%Lung cancer is one of the most common malignant tumor in the world, severely threatening human life. Recently, targeted therapy such as the epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) made huge progress in treatment of lung cancer. EGFR-TKIs, with its high selectivity and low toxicity, is the ifrst choice for EGFR-mutated patients in stage IV non-small cell lung cancer (NSCLC). However, secondary drug resistance becomes a clinical problem to be urgently resolved. In recent years, a series of preclinical studies showed that EGFR-TKI can enhance the antitumor activ-ity of ionizing radiation. hTerefore, EGFR-TKI combined with radiation is extremely promising therapy pattern for advanced NSCLC. hTis review will discuss the research status in EGFR-TKI and radiotherapy for advanced NSCLC.

    Full Text Available Lung cancer is one of the most common malignant tumors in China and ranks the first of cancer-related death. The major etiological agent of lung cancer is an industry-made and promoted addictive product, so lung cancer is considered to be a unique disease in all cancers. Effective policies for public health are required to prevent the smoking initiation so as to reduce the mortality of lung cancer, so Food and Drug Administration (FDA has introduced a series of measures to monitor the tobacco products. As to patients with strong suspicion of lung cancer in stage Ⅰ-Ⅱ, a preoperative biopsy is needed and intra-operative diagnosis is necessary before pneumonectomy, bilobectomy or lobectomy if the preoperative tissue diagnosis is not obtained. However, lung cancer still cannot be easily diagnosed and cured, so the annual improvement and update of new therapeutic protocols and the development of new agents is of great significance. Non-small cell lung cancer (NSCLC accounts for about 80% of all lung cancer, and above 75% NSCLC patients are in middle-advanced stage when diagnosed, so they have lost the optimal therapeutic opportunity and the 5-year survival rate is relatively low. Therefore, this study mainly interpreted the National Comprehensive Cancer Network (NCCN guidelines on the general therapies on NSCLC, hoping to provide references for the treatment of NSCLC patients and prolong their long-term survival.

The epidermal growth factor receptor (EGFR is often overexpressed in NSCLC and represents a relevant target for specific treatments. Although EGFR mutations are more frequent in non-squamous histology, the receptor itself is more often overexpressed in squamous NSCLC. Necitumumab is a human monoclonal antibody that is able to inhibit the EGFR pathway and cause antibody-dependent cell cytotoxicity. This drug has been studied in combination with first-line chemotherapy for advanced NSCLC in two Phase III trials, and a significant survival benefit was reported in squamous NSCLC (SQUIRE trial; by contrast, necitumumab did not prove itself beneficial in non-squamous histotype (INSPIRE trial. On the basis of the SQUIRE results, necitumumab was approved in combination with cisplatin and gemcitabine as a first-line treatment for advanced squamous NSCLC, both in the US and Europe, where its availability is limited to patients with EGFR-expressing tumors. The aim of this review is to describe the tolerability and the efficacy of necitumumab by searching the available published data and define its potential role in the current landscape of NSCLC treatment.

During the last decades, the survival has only improved significantly for lung cancer patients who have tumors harboring a driver mutation. Therefore, there is a clear unmet need for effective therapies for patients with no mutation. Immunotherapy has emerged as an effective treatment for different cancer types. Nivolumab, a monoclonal inhibitory antibody against PD-1 receptor, can prolong survival of NSCLC patients, with a manageable toxicity profile. In two Phase III trials, nivolumab was compared to docetaxel in patients with, respectively, squamous (CheckMate 017 and non-squamous NSCLC (CheckMate 057. In both trials, nivolumab significantly reduced the risk of death compared to docetaxel (41% and 27% lower risk of death for squamous and non-squamous NSCLC, respectively. Therefore, nivolumab has been approved in the US and in Europe as second-line treatment for advanced NSCLC. Unfortunately, accurate predictive factors for patient selection are lacking, making it difficult to decide who will benefit and who will not. Currently, there are many ongoing trials that evaluate the efficacy of nivolumab in different settings and in combination with other agents. This paper reviews the present literature about the role of nivolumab in the treatment of NSCLC. Particular attention has been given to efficacy studies, toxicity profile, and current and emerging predictive factors.

    Full Text Available Brain metastases (BM are a common and lethal complication of non-small cell lung cancer (NSCLC which portend a poor prognosis. In addition, their management implies several challenges including preservation of neurological and neuro-cognitive function during surgery or radiation -therapy, minimizing iatrogenic complications of supportive medications, and optimizing drug delivery across the blood brain barrier (BBB. Despite these challenges, advancements in combined modality approaches can deliver hope of improved overall survival and quality of life for a subset of NSCLC patients with BM. Moreover, new drugs harnessing our greater understanding of tumour biology promise to build on this hope. In this mini-review, we revised the management of BM in NSCLC including advancements in neurosurgery, radiation therapy, as well as systemic and supportive therapy.

    Background Antiangiogenesis plays a key role in the treatment of non-small lung cancer (NSCLC). We observed the cavitation of lesions in patients with stage IIIB/IV NSCLC treated with Endostar and vinorelbine-cisplatin (NP) chemotherapy, and evaluated the imaging characteristics and clinical outcome of patients who developed tumor cavitation. Methods Our study included 105 untreated NSCLC patients who received Endostar in combination with NP chemotherapy at the Tianjin Lung Cancer Center. Chest computed tomography (CT) was performed to evaluate the efficacy every two cycles. The number of activated circulating endothelial cells (aCECs) was measured by flow cytometry. Rates of tumor cavitation were documented and their clinical CT imaging data were analyzed. Results Tumor cavitation occurred in 11 of the 105 (10.5%) patients treated with Endostar and NP. The response rates were 37.2% (35/94) in patients without cavitation, 27.3% (3/11) evaluated by Response Evaluation Criteria in Solid Tumors, and 100.0% (11/11) if evaluated by an alternate method in patients who developed cavitation. Three of the 11 cases with cavitation had a centrally located tumor. No patients had hemoptysis or any other severe side effects. Compared with patients not developing cavitation, cavity formation resulted in a longer median survival time (13.6 vs. 11.8 months, P = 0.011) and an increase in the number of aCECs (244.4/105 vs. 23.3/105, P = 0.000). Conclusions Intratumoral cavitation induced by Endostar is common in NSCLC patients, and is not correlated with squamous histology, tumor location or pulmonary hemorrhage. Cavitation might have a significant effect on the number of aCECs and overall prognosis. PMID:26767036

    2002-01-01

    Objective: To investigate the expression of p120ctn in non-small-cell lungcancer (NSCLC) and its relationship with clinicopathological factors and prognosis. Methods: p120ctn expression was tested by immunohistochemistry for 80 tumors from patients with non-small-cell lung cancer. Correlations were investigated between p120ctn immunostaining in primary tumors and clinicopathological characteristics and survival. Results: Abnormal expression of p120ctn was found in 68/80(85%) tumors in which 43 cases had cytoplasmic staining. Abnormal staining of p120ctn was related with high TNM stage (P=0.003) and nodal metastasis (P=0.024).However, there was no correlation between altered expression with poor differentiation and histological type. According to Kaplan-Meier survival estimate, the expression of p120ctn was related to the poor survival (P=0.015) of patients. A Cox regression analysis revealed that p120ctn expression was a significant independent factor in the prediction of survival for patients with non-small-cell lung cancer (P=0.008). Conclusion: altered expression of p120ctn was found in non-small-cell lung cancers and was correlated with lymph node metastasis and prognosis. From a practical point of view, the expression of p120ctn can be of prognostic value for patients with non-small-cell lung cancer.

An improvement in the understanding of the role of the immune system in tumor immunosurveillance has led to the development of the programmed death-1 (PD-1 immune checkpoint inhibitor nivolumab (Opdivo. Nivolumab is the first PD-1 inhibitor approved for the treatment of advanced-stage squamous cell non-small-cell lung cancer following platinum-based chemotherapy. In the key Phase III trial CHECKMATE 017, a better overall survival and progression-free survival were seen in patients treated with second-line nivolumab compared with docetaxel. Programmed death ligand-1 (PD-L1 expression did not predict for outcome. In addition, nivolumab had better safety and tolerability, and led to better patient reported outcomes. Further research on the role of PD-L1 expression as a predictive biomarker should be performed, and other biomarkers that can predict the efficacy of PD-1/PD-L1 inhibitors should also be pursued. Further studies on the combination treatment are ongoing to determine the optimal role of nivolumab as monotherapy or nivolumab with other agents in non-small-cell lung cancer.

However, it is unclear whether pemetrexed-based doublet therapy improves treatment efficacy and safety. Thus, this meta-analysis was performed to resolve this controversial question. Methods: Electronic databases, including PubMed, Embase, and the Cochrane Central Register of Controlled Trials were searched for relevant articles before April 2015. Hazard ratios (HRs were used to estimate overall survival (OS and progression-free survival (PFS, and odds ratios (ORs were used to analyze the overall response rate (ORR and grade ≥3 toxicities. Subgroup analysis, sensitivity analysis, and publication bias were also evaluated. Results: A total of 2,519 patients from ten randomized controlled trials were included. Compared to pemetrexed alone, PFS and ORR significantly improved in the pemetrexed-based doublet group (HR, 0.86; 95% CI [confidence interval], 0.75–0.99; P=0.038; and OR, 1.98; 95% CI, 1.25–3.12; P=0.003, respectively. However, no statistically significant differences in OS were observed between groups (HR, 0.92; 95% CI, 0.83–1.02; P=0.132. In addition, subgroup analyses indicated that improved OS was only observed in nonsquamous NSCLC patients who received the combination of pemetrexed and erlotinib. An increasing incidence of grade ≥3 neutropenia and thrombocytopenia was observed in the pemetrexed

    2008-01-01

    Objective: To evaluate the effects of Aidi injection on vinorelbine plus cisplatin (NP) chemotherapy for advanced non-small cell lung cancer (NSCLC). Methods: Ninety eight patients with advanced NSCLC were randomized to receive either NP alone or NP plus Aidi injection every 3 weeks. The primary endpoint was overall survival; secondary endpoints included overall response rate, time to progression, and safety. Results: The median overall survival time was 11.6 months in NP plus Aidi-treated patients and 10.1 months in NP alone-treated ones, and 1- and 2-year survival rates were higher in the former (47% and 22%) than the latter (42% and 15%). The overall response rates in Aidi injection plus NP-treated patients tended to be higher but not statistically significant compared with NP alone-treated ones. The occurrence rates of grades 3 or 4 toxicities, e.g. fatigue, nausea, vomiting, appetite loss, leucopenia, thrombocytopenia and anemia, were lower in Aidi injection plus NP-treated patients than NP alone-treated ones, although not significantly different between them. Conclusion: Aidi injection promotes NP chemotherapeutic effects, reduces the toxicities, and improves the patients' tolerance to chemotherapy as well. It may be an effective adjunct to chemotherapy in patients with NSCLC.

    Background: Current histopathological classification and TNM staging have limited accuracy in predicting survival and stratifying patients for appropriate treatment. The goal of the study is to determine whether the expression pattern of functionally important regulatory proteins can add additional values for more accurate classification and prognostication of non-small lung cancer (NSCLC). Methods: The expression of 108 proteins and phosphoproteins in 30 paired NSCLC samples were assessed using Protein Pathway Array (PPA). The differentially expressed proteins were further confirmed using a tissue microarray (TMA) containing 94 NSCLC samples and were correlated with clinical data and survival. Results: Twelve of 108 proteins (p-CREB(Ser133), p-ERK1/2(Thr202/Tyr204), Cyclin B1, p-PDK1(Ser241), CDK4, CDK2, HSP90, CDC2p34, β-catenin, EGFR, XIAP and PCNA) were selected to build the predictor to classify normal and tumor samples with 97% accuracy. Five proteins (CDC2p34, HSP90, XIAP, CDK4 and CREB) were confirmed to be differentially expressed between NSCLC (n=94) and benign lung tumor (n=19). Over-expression of CDK4 and HSP90 in tumors correlated with a favorable overall survival in all NSCLC patients and the over-expression of p-CREB(Ser133) and CREB in NSCLC correlated with a favorable survival in smokers and those with squamous cell carcinoma, respectively. Finally, the four proteins (CDK4, HSP90, p-CREB and CREB) were used to calculate the risk score of each individual patient with NSCLC to predict survival. Conclusion: In summary, our data demonstrated a broad disturbance of functionally important regulatory proteins in NSCLC and some of these can be selected as clinically useful biomarkers for diagnosis, classification and prognosis.

  5. Induction gemcitabine in standard dose or prolonged low-dose with cisplatin followed by concurrent radiochemotherapy in locally advanced non-small cell lung cancer: a randomized phase II clinical trial

    International Nuclear Information System (INIS)

    The optimal combination of chemotherapy with radiation therapy for treatment locally advanced non-small cell lung cancer (NSCLC) remains an open issue. This randomized phase II study compared gemcitabine in two different schedules and cisplatin - as induction chemotherapy, followed by radiation therapy concurrent with cisplatin and etoposid. Eligible patients had microscopically confirmed inoperable non-metastatic non-small cell lung cancer; fulfilled the standard criteria for platin-based chemotherapy; and signed informed consent. Patients were treated with 3 cycles of induction chemotherapy with gemcitabine and cisplatin. Two different aplications of gemcitabine were compared: patients in arm A received gemcitabine at 1250 mg/m2 in a standard half hour i.v. infusion on days 1 and 8; patients in arm B received gemcitabine at 250 mg/m2 in prolonged 6-hours i.v. infusion on days 1 and 8. In both arms, cisplatin 75 mg/m2 on day 2 was administered. All patients continued treatment with radiation therapy with 60–66 Gy concurrent with cisplatin 50 mg/m2 on days 1, 8, 29 and 36 and etoposid 50 mg/m2 on days 1–5 and 29–33. The primary endpoint was response rate (RR) after induction chemotherapy; secondary endpoints were toxicity, progression-free survival (PFS) and overall survival (OS). From September 2005 to November 2010, 106 patients were recruited to this study. No statistically signifficant differences were found in RR after induction chemotherapy between the two arms (48.1% and 57.4%, p = 0.34). Toxicity profile was comparable and mild with grade 3/4 neutropenia as primary toxicity in both arms. One patient in arm B suffered from acute peripheral ischemia grade 4 and an amputation of lower limb was needed. With a median follow-up of 69.3 months, progression-free survival and median survival in arm A were 15.7 and 24.8 months compared to 18.9 and 28.6 months in arm B. The figures for 1- and 3-year overall survival were 73.1% and 30.8% in arm A, and 81.5 % and

    The present study aims to investigate expression pattern and biological roles of TRIM31 in human non-small cell lung cancer (NSCLC). We examined TRIM31 expression in 116 NSCLC tissues and 20 corresponding normal lung tissues by immumohistochemistry. We found TRIM31 downregulation in 47 out of 116 (40.5 %) cancer samples, which correlated with tumor status (p=0.0132), advanced p-TNM stage (p=0.001), and nodal metastasis (p=0.0382). TRIM31 expression was lower in lung cancer cell lines than normal bronchial cell line HBE. Transfection of TRIM31 plasmid was performed in H157 and H1299 cells. TRIM31 overexpression inhibited cell growth rate and colony formation ability in both cell lines. In addition, expression of cell cycle regulator cyclin D1 and cyclin E were decreased after TRIM31 transfection. In conclusion, TRIM31 might serve as a tumor suppressor in non-small cell lung cancer.

    Full Text Available Monika Joshi, Syed M Rizvi, Chandra P Belani Penn State Milton S Hershey Medical Center, Department of Medicine, Division of Hematology-Oncology, Hershey, PA, USA Abstract: Targeting the epidermal growth factor receptor (EGFR in patients with non-small cell lung cancer (NSCLC harboring sensitizing mutations in the tyrosine kinase (TKI domain has led to a significant change in the management of this disease. The classic or sensitizing mutations are G719X mutation in exon 18, in-frame deletions or insertion of exon 19, L858R or L861Q mutation in exon 21. Approximately 90% of these mutations are exon 19 deletion or exon 21 L858R point mutation. Gefitinib and erlotinib are reversible first-generation inhibitors of mutant EGFR, and treatment with these agents in the first-line setting has demonstrated a progression-free survival of 9.5–13.7 months. However, the majority of these patients ultimately develop resistance to these drugs. Afatinib is an irreversible pan-ErbB inhibitor that was developed to circumvent the problem of resistance to first-generation TKIs. The LUX-Lung studies have evaluated the efficacy and toxicities of afatinib in treatment-naïve and refractory NSCLC patients. The promising results of some of these trials led to approval of afatinib by the US Food and Drug Administration for patients with advanced NSCLC and EGFR exon 19 deletions or exon 21 (L858R substitution mutations. Afatinib causes toxicities similar to those of the first-generation EGFR TKIs, such as diarrhea, rash, acne, and stomatitis, and overall is well tolerated. This article focuses on the clinical studies of afatinib in patients with NSCLC. Keywords: afatinib, non-small cell lung cancer, epidermal growth factor receptor, tyrosine kinase inhibitor

    Full Text Available Lung cancer disease diagnosis and treatment is costly. As the numbers of inflicted rise so does the economic burden assumed for this cancer type. When the treatment expenditures are considered for all types of cancer, the lung cancer is thought to occupy a 20% share. The disease examined in two basic groups as small-cell lung cancer and non-small cell lung cancer (NSCLC is the most frequently encountered type of its kind nationally and in the World. This study considers the cost, effectiveness and cost effectiveness of platinum based chemotherapy medications with active ingredients pemetrexed and gemcitabine used for NSCLC. A review of studies relevant to the advanced stage NSCLC where majority of patients are positioned is foreseen to be useful to the decision makers since policy makers, regulating authorities and physicians require more information due to increased overall finance and costs, as well as treatment cost effectiveness. Furthermore, due to the entry attempt of pemetrexed active ingredient to the list of reimbursed medications for the first stage lung cancer treatment, it is assumed that a review of studies containing pemetrexed and gemcitabine will draw the attention of decision makers at the Social Security Instutition.

    Patients aged 70 and over represent the third of the population of patients with lung cancer. There has been for a long time a certain nihilism regarding the treatment of elderly patients with advanced lung cancer as well from medical doctors but also from families and patients themselves with the false belief of an indolent course of the disease in elderly patients. As a result, clinical trials devoted to elderly patients were quite scarce until the end of the last decade. Nevertheless, an important trial was published in 1999 with the comparison of vinorelbine as a single agent versus best supportive care only in patients aged 70 and over with an advanced non-small cell lung cancer. The survival benefit with vinorelbine was important. Then two trials were published comparing monotherapy with either vinorelbine or gemcitabine to the doublet vinorelbine and gemcitabine without convincing results. As a consequence, the ASCO 2004 recommendations were to treat elderly patients with a monotherapy (gemcitabine or vinorelbine). Recently an IFCT trial was presented at the plenary session of the ASCO 2010. A carboplatin (every 4weeks)+weekly paclitaxel doublet was compared to a vinorelbine or gemcitabine (choice of the center). The survival benefit was of such magnitude that the paradigm of treatment of elderly patients PS 0-2 with advanced NSCLC should be modified in favor of the tested doublet. There should be a reappraisal of the geriatric indexes recommended by the oncogeriatricians regarding their exact prognostic or predictive role. PMID:21388776

    Full Text Available Background and objective Sequential and concurrent chemoradiotherapy were widely studied in locally advanced non-small cell lung cancer (NSCLC, but the reports of induction chemotherapy followed concurrent chemoradiotherapy are rare so far. The little side effects of paclitaxel liposme may be convenient to carry out induction chemotherapy followed concurrent chemoradiotherapy. The aim of this study is to compare the effects and side effects of TP regimen (Paclitaxel liposme and cisplatin induction chemotherapy followed concurrent chemoradiotherapy with sequential radiotherapy on locally advanced NSCLC. Methods Sixty locally advanced NSCLC patients were randomly divided into group A, induction chemotherapy followed concurrent chemoradiotherapy and group B, sequential radiotherapy group. The patients in group A received 2-3 cycles of induced chemotherapy included of Paclitaxel liposme 135 mg/m2-175 mg/m2, d1 and cisplatin 70 mg/m2-80 mg/m2, d2, 3 weeks repeat and after 2-3 cycles followed by concurrent chemoradiotherapy. The patients in group B received chemotherapy, (as described above in group A 4-6 cycles of chemotherapy followed one cycle of radiotherapy. The three-dimensional conformal radiotherapy at the total dose of 56 Gy-70 Gy was applied in all patients. Results The response rate in group A and group B were 80.3% and 60%, respectively (P=0.042. 1-year survival rates were 71.4% and 53.2%, respectively (P=0.18. And there were no significant difference of myelosuppression, radiation esophagitis and pulmonary fibrosis between the two groups (P=0.09, P=0.147, P=0.276, respectively. Conclusion The recent effects of induction chemotherapy followed by concurrent chemoradiotherapy group were better than sequential radiotherapy group on locally advanced NSCLC and there was no significant difference in side effects between the two groups.

    Pemetrexed has been widely used in patients with advanced non-small cell lung cancer (NSCLC). The clinical relevance of polymorphisms of folate pathway genes for pemetrexed metabolism have not been fully elucidated yet. The aim of this study was to evaluate the expression levels of circulating miR-22, miR-24, and miR-34a, possibly involved in folate pathway, in NSCLC patients treated with pemetrexed compared with healthy controls and to investigate their impact on patient clinical outcomes. A total of 22 consecutive patients with advanced NSCLC, treated with pemetrexed-based chemotherapy and 27 age and sex matched healthy controls were included in this preliminary analysis. miR-22, miR-24, and miR-34a targets were identified by TargetScan 6.2 algorithm, validating the involvement of these microRNAs in folate pathway. MicroRNAs were isolated from whole blood and extracted with miRNAeasy Mini Kit (Qiagen). miRNA profiling was performed using Real-Time PCR. SPSS 17 was used to data analysis. miR-22, miR-24, and miR-34a were found upregulated (P<0.05) in NSCLC patients versus healthy controls. Higher expression levels were recorded for miR-34a. Nevertheless, significantly higher miR-22 expression was observed in patients developing progressive disease (P=0.03). No significant associations with clinical outcome were recorded for miR-24 and miR-34a. Albeit preliminary, these data support the involvement of miR-22, miR-24, and miR-34a in advanced NSCLC. The correlation between high expression of miR-22 in whole blood and the lack of response in pemetrexed treated NSCLC patients indicates that miR-22 could represent a novel predictive biomarker for pemetrexed-based treatment.

    放化综合治疗是局部晚期非小细胞肺癌(NSCLC)的基本治疗策略.近期研究表明同期放化疗在生存率等方面优于序贯治疗,已成为局部晚期NSCLC的标准治疗模式,但是尚无具体放化结合模式指导临床治疗.为了进一步提高治疗疗效,目前临床研究主要集中于以下几个方面:同期放化治疗加入诱导或巩固化疗、同期放化疗中放疗分割方式的改变、同期放化疗中化疗方式及方案的选择、同期放化疗加入分子靶向治疗.%Combination of chemotherapy and radiotherapy is foundational treatment approach for locally advanced non- small cell lung cancer (NSCLC) patients. Concomitant chemo-radiotherapy have been demons-trated to be better than sequential chemoradiotherapy in survival rate, and it is considered as a standard approach in patients with locally advanced NSCLC. However, the chemo-radiotherapy regimens remain uncert-ain. The main clinical researches aiming at improving the survival rate of locally advanced NSCLC patients are the addition of induction or consolidation, the alteration of radiation fractionation, the alteration of chemo schema and the inte- gration of molecularly targeted therapies combining with concurrent chemo-radiotherapy.

    Non-small cell lung cancer (NSCLC) constitutes the most common type of lung cancer and is frequently diagnosed at advanced stages. Clinical studies have shown that molecular targeted therapies increase survival and improve quality of life in patients. Nevertheless, the realization of personalized therapies for NSCLC faces a number of challenges including the integration of clinical and genetic data and a lack of clinical decision support tools to assist physicians with patient selection. To address this problem, we used frequent pattern mining to establish the relationships of patient characteristics and tumor response in advanced NSCLC. Univariate analysis determined that smoking status, histology, epidermal growth factor receptor (EGFR) mutation, and targeted drug were significantly associated with response to targeted therapy. We applied four classifiers to predict treatment outcome from EGFR tyrosine kinase inhibitors. Overall, the highest classification accuracy was 76.56% and the area under the curve was 0.76. The decision tree used a combination of EGFR mutations, histology, and smoking status to predict tumor response and the output was both easily understandable and in keeping with current knowledge. Our findings suggest that support vector machines and decision trees are a promising approach for clinical decision support in the patient selection for targeted therapy in advanced NSCLC.

    Chemotherapy paclitaxel yields significant reductions in tumor burden in the majority of advanced non-small cell lung cancer (NSCLC) patients. However, acquired resistance limits its clinical use. Here we demonstrated that the histone deacetylase (HDAC) was activated in paclitaxel-resistant NSCLC cells, and its activation promoted proliferation and tumorigenesis of paclitaxel-resistant NSCLC cells in vitro and in vivo. By contrast, knockdown of HDAC1, a primary isoform of HDAC, sensitized res...

  7. Evaluation of safety and efficacy of tivantinib in the treatment of inoperable or recurrent non-small-cell lung cancer

    International Nuclear Information System (INIS)

    Tivantinib is a selective, oral, non-ATP-competitive, small molecule inhibitor of the c-Met receptor, tyrosine kinase, which is implicated at different levels of tumor cell migration, invasion, proliferation, and metastasis. Tivantinib has shown antitumor activity in various human tumor cell lines and in xenograft models of human cancers, including non-small-cell lung cancer. Few therapeutic options are available at present for advanced non-small-cell lung cancer, so there is a pressing need for new therapeutic strategies to improve response and survival. Amplification of Met has been reported in more than 20% of lung tumors that have acquired resistance to epidermal growth factor receptor inhibitors, implying that treatment of these tumors with a c-Met inhibitor should overcome resistance. Tivantinib has shown interesting and promising results in advanced non-small-cell lung cancer and appears to be well tolerated, either alone or in combination with other drugs. An interesting additional feature is the ability of the drug to delay development of new metastasis, in agreement with the proposed role of Met in this particular setting

    Non-small cell lung cancer(NSCLC) is a highly prevalent and aggressive disease. In recent years, the long time survival rate of patients with advanced NSCLC remains low despite of advances in surgery, irradiation, chemotherapy and targeted ther-apy. The aim of immunotherapy is to specifically enhance the immune response directed to the tumor. Many trials have addressed the role of novel immunotherapeutic agents, such as checkpoint inhibitors and antigenspecific tumour vaccines, which has made break-through progress in NSCLC. Immunotherapy will be a fundamentally new concept for the treatment of NSCLC.%非小细胞肺癌(NSCLC)是一种高发病率和死亡率的恶性肿瘤。近年来以手术、放疗、化疗和靶向治疗为主的综合治疗均取得了一定进展,但晚期 NSCLC 患者的远期生存率仍然较低。免疫治疗主要通过特异性地增强机体的抗肿瘤免疫应答来杀伤肿瘤细胞。以免疫检查点抑制剂、抗原特异性肿瘤疫苗等为代表的多种新型免疫治疗药物在近期临床试验中显示出较好的疗效,从而使得 NSCLC 的治疗取得突破性进展。免疫治疗将成为 NSCLC 重要的治疗新模式。

    Full Text Available Abstract Background Nitric oxide (NO is a free radical that is involved in carcinogenesis. Endothelial NO, synthesized from L-arginine by endothelial NO synthase (eNOS, inhibits apoptosis and promotes angiogenesis, tumor cell proliferation and metastasis. The aim of this study was to evaluate the influence of polymorphisms in the eNOS gene on prognosis of patients with advanced stage non-small-cell lung cancer (NSCLC. Methods Unresectable, chemotherapy naïve stage III or IV NSCLC patients who were treated with standard platinum-containing doublet regimens were analyzed. All individuals were genotyped for the single-nucleotide polymorphism G894T in exon 7 of the eNOS gene and for a variable number of tandem repeats (VNTR polymorphism in intron 4 that results in a rare smaller allele (a and a common larger allele (b, to investigate the association between these polymorphisms and clinical outcomes. The primary endpoint was correlation with overall survival. Results From October 2004 to December 2007, 108 patients (male/female, 66/42; Stage IIIA/IIIB/IV, 6/30/72 aged 29-77 years (median 63 with good performance status were consecutively enrolled in this study. Using Kaplan-Meier estimates, we showed that 5-year overall survival was significantly increased in patients carrying the VNTR a-allele compared with VNTR b/b patients (P = 0.015. In multivariate Cox proportional hazard analysis, the VNTR polymorphism was an independent prognostic factor for survival. Conclusions The results support the role of the VNTR polymorphism in intron 4 as a marker for survival in patients with advanced stage NSCLC who are candidates for standard chemotherapy.

    Full Text Available Abstract Background In the first line treatment of non-small cell lung cancer (NSCLC, several clinical trials have shown that not all NSCLC patients can benefit from treatment with tyrosine kinase inhibitors (TKIs than receiving chemotherapy. Some trials treated patients with TKI according to their clinical characteristics. A few studies only chose patients with an epidermal grouth factor receptor (EGFR mutation for TKI therapy. We aimed to determine whether patients could be treated with TKIs based on clinical factors in the first-line setting. Methods We performed a meta-analysis of randomized trials involving patients with advanced NSCLC treated with chemotherapy or TKIs by different selections. Efficacy outcomes of interest were the objective response rate (ORR, progression-free survival (PFS and the overall survival (OS of each treatment arm. Results Four trials enrolled unselected patients, and two trials selected East Asian patients using the clinical factors of gender and smoking history. Five trials chose patients with an EGFR mutation who were randomized for treatment with TKI or chemotherapy. For unselected patients, the risk ratio (RR of the ORR was 3.52, the hazard ratio (HR of the PFS was 1.29 and the HR of the OS was 1.35. For the clinically selected patients, the RR of the ORR was 0.64. The HRs of the PFS and OS were 0.83 and 0.92, respectively. The ORR and PFS were better for TKIs than for chemotherapy in patients with an EGFR mutation. The ORR was 0.47, and the HRs of the PFS and OS were 0.36 and 1.00, respectively. Conclusions Advanced NSCLC patients with an EGFR mutation benefit most from TKIs. EGFR-TKI treatment is justified for patients with unknown EGFR status,and those who cannot tolerate chemotherapy owing to age, poor performance status (PS or other medical conditions, when selected according to clinical factors in the first-line setting.

    The aim of the study was to evaluate the effectiveness of combined treatment of locally advanced lung cancer with the use of neoadjuvant chemotherapy and surgery with the use of pre- and intraoperative photodynamic therapy. 20 patients with IIIa (n=7) and IIIb (n=13) stage of non-small cell lung carcinoma were included. At the time of diagnosis the surgical treatment was decided to abstain because of the trachea invasion in 9 patients, wide mediastinal invasion in 2 patients and contralateral mediastinal lymph nodes metastases in 2 patients; pneumonectomy was not possible due to the poor respiratory function in 7 patients. Neoadjuvant therapy included 3 courses of chemotherapy and endobronchial photodynamic therapy. During the operation, along with the lung resection (pneumonectomy - 15, lobectomy - 5), photodynamic therapy of the resection margins were carried out. No adjuvant treatment was done. Preoperative treatment led to partial regress of the disease in all cases; the goal of surgery was the complete tumor removal. No complications of the photodynamic therapy were observed. 18 surgical interventions were radical and two non-complete microscopically (R1). Postoperative morbidity was 20%, one patient died due to massive gastrointestinal bleeding. The average follow-up period was 18 months: 19 patients were alive, of them 18 with no signs of the disease recurrence. The first experience of the combined use of neoadjuvant chemotherapy and surgery with pre- and intraoperative photodynamic therapy demonstrates safety and efficacy of the suggested treatment tactics.

    Overexpression of TMPRSS4, a cell surface-associated transmembrane serine protease, has been reported in pancreatic, colorectal and thyroid cancers, and has been implicated in tumor cell migration and metastasis. Few reports have investigated both TMPRSS4 gene expression levels and the protein products. In this study, quantitative RT-PCR and protein staining were used to assess TMPRSS4 expression in primary non-small cell lung carcinoma (NSCLC) tissues and in lung tumor cell lines. At the tra...

    2012-01-01

    Non-small cell lung cancer (NSCLC) is the deadliest form of lung cancer and has a poor prognosis due to its high rate of metastasis. Notably, metastasis is one of the leading causes of death among cancer patients. Despite the clinical importance, the cellular and molecular mechanisms that govern the initiation, establishment and progression of metastasis remain unclear. Moreover, knowledge gained on metastatic process was largely based on cultured or in vitro manipulated cells that were reint...

    Non-small-cell lung cancer (NSCLC) is often diagnosed at an advanced stage of disease, where it is no longer amenable to curative treatment. During the last decades, the survival has only improved significantly for lung cancer patients who have tumors harboring a driver mutation. Therefore, there is a clear unmet need for effective therapies for patients with no mutation. Immunotherapy has emerged as an effective treatment for different cancer types. Nivolumab, a monoclonal inhibitory antibody against PD-1 receptor, can prolong survival of NSCLC patients, with a manageable toxicity profile. In two Phase III trials, nivolumab was compared to docetaxel in patients with, respectively, squamous (CheckMate 017) and non-squamous NSCLC (CheckMate 057). In both trials, nivolumab significantly reduced the risk of death compared to docetaxel (41% and 27% lower risk of death for squamous and non-squamous NSCLC, respectively). Therefore, nivolumab has been approved in the US and in Europe as second-line treatment for advanced NSCLC. Unfortunately, accurate predictive factors for patient selection are lacking, making it difficult to decide who will benefit and who will not. Currently, there are many ongoing trials that evaluate the efficacy of nivolumab in different settings and in combination with other agents. This paper reviews the present literature about the role of nivolumab in the treatment of NSCLC. Particular attention has been given to efficacy studies, toxicity profile, and current and emerging predictive factors. PMID:27536062

    Full Text Available Background: The clinical relevance of bone marrow micrometastasis (BMM in non-small-cell lung cancer is undetermined, and the value of such analyses in advanced stage patients has not been clearly assessed previously. This study was conducted to estimate the accuracy of both polymerase chain reaction (PCR and immunohistochemistry (IHC in micrometastases detection and determine the best site for bone marrow biopsy in order to find micrometastasis. Methods: This prospective cross-sectional study was performed in the Department of Thoracic Surgery, Alzahra University Hospital from September 2008 to June 2009. To evaluate the bone marrow, a 3-cm rib segment and an aspirated specimen from the iliac bone prior to tumor resection were taken. PCR and IHC were performed for each specimen to find micrometastasis. Results: Of 41 patients, 14 (34% were positive for BMM by PCR compared with two positive IHC (4.8%. All BMMs were diagnosed in rib segments, and iliac specimens were all free from metastatic lesion. Our data showed no significant association between variables such as age, sex, histology, tumor location, side of tumor, involved lobe, smoking, or weight loss and presence of BMM. Conclusion: PCR could use as a promising method for BMM detection. BMM in a sanctuary site (rib is not associated with advanced stages of lung cancer. In addition, when predictor variables such as age, sex, histology, tumor location, smoking, or weight loss are analyzed, no correlation can be found between micrometastasis prevalence and any of those variables.

    Background: Recursive partitioning analysis has shown that Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) ≥2, male sex, and age ≥70 years are prognostic of poor outcome in locally advanced non-small cell lung cancer (LA-NSCLC) patients. Concurrent chemoradiation therapy (CRT) improves survival, but toxicity is a concern in this frail patient cohort. We therefore opened this trial of concurrent definitive thoracic radiation therapy (XRT) and cetuximab, followed by consolidation docetaxel plus cetuximab. Methods and Materials: Eligible patients had pathologically proven, unresectable LA-NSCLC (stage IIA-“dry” IIIB). They had ECOG PS 2 or weight loss ≥5% in 3 months or were aged ≥70 years. The primary objective was progression-free survival (PFS). Secondary objectives included overall survival (OS) and overall response rate (ORR). Results: From May 2008 to November 2010, a total of 32 patients were evaluated in our single-institution, institutional review board–approved prospective clinical trial. Three patients were screen failures and 2 more withdrew consent before treatment, leaving 27 evaluable patients. One was removed because of poor therapy compliance, and 2 were taken off trial because of grade 3 cetuximab-related toxicities but were followed up under intent-to-treat analysis. The median follow-up and OS were 10.5 months. The median PFS was 7.5 months. The ORR was 59.3%. Eight early/sudden deaths were reported. Upon review, 6 patients developed severe pulmonary complications. Conclusions: Patients enrolled in this trial had improved OS compared with poor-PS historical controls (10.5 vs 6.4 months) and comparable OS to good-PS historical controls (10.5 vs 11.9 months) treated with XRT alone. However, pulmonary toxicity is a concern. Consolidative cetuximab/docetaxel, in conjunction with high-dose radiation therapy, is a putative cause.

    Purpose: To investigate the safety and efficacy of concurrent vinorelbine and thoracic radiotherapy in elderly patients with locally advanced non-small-cell lung cancer (NSCLC). Methods and Materials: Eligible patients were 71 years of age or older with unresectable Stage III NSCLC. Patients were treated with thoracic radiotherapy (60 Gy) and concurrent vinorelbine (20 mg/m{sup 2} in Level 1 and 25 mg/m{sup 2} in Level 2) on Days 1 and 8 every 3 weeks for two cycles, followed by adjuvant vinorelbine (25 mg/m{sup 2}) on Days 1 and 8 every 3 weeks for two cycles. Results: Four patients were enrolled at Level 1. One patient experienced Grade 3 febrile neutropenia at Level 1 and the dose was escalated to Level 2. At Level 2, 2 of 6 patients experienced dose-limiting toxicities (Grade 4 neutropenia in 1 patient and Grade 3 infection in another). Three of 6 patients developed late Grade 2 or 3 pneumonitis. Therefore, the dose was de-escalated to Level 1. An additional 6 patients were enrolled at Level 1, 4 of whom experienced dose-limiting toxicities (incomplete radiotherapy because of Grade 2 pneumonitis in 1 patient and Grade 3 infection in 1, Grade 3 febrile neutropenia in 1, and Grade 3 esophagitis in 1). Moreover, late Grade 3 pneumothorax and Grade 5 pneumonitis occurred in 1 and 1 patient, respectively. Overall, Grade 2, 3 and 5 pneumonitis occurred in 3, 3, and 1 among 16 patients, respectively. Conclusions: Concurrent vinorelbine and thoracic radiotherapy resulted in a high incidence of severe pneumonitis when the standard dose of this agent was used for elderly patients. We therefore recommend caution in the use of this regimen and schedule for elderly patients.

    Topotecan, a semi-synthetic camptothecin analogue with topoisomerase I interaction, has shown to be an active agent in the treatment of advanced refractory lung cancer. This paper describes the authors' experience with this drug when used as a single agent in patients (pts) with advanced non-small cell lung cancer (NSCLC) refractory to platinum- and taxane-containing chemotherapy regimens. Thirty-five patients with NSCLC refractory to previous chemotherapy and KI ≥ 60% were included in the study. Their characteristics are as follows: median age of 52 years (range 43-69) and Karnofsky PS of 70 (60-80); 27 were male and 8 were female. Twenty-one (60%) patients had adenocarcinoma; eleven (31.4%), squamous cell, and three (8.5%), undifferentiated carcinoma. There was a median of two disease sites and two prior chemotherapy regimens. Topotecan was administered at a dose of 1.25 mg/m(2) I.V. daily for 5 days, repeated every 21 days until disease progression, maximal response, or intolerable toxicity. After 73 cycles, patients received a median of 2 treatment cycles (1-9). All patients except one were considered evaluable for toxicity; eight episodes (24%) of nausea/vomiting and two episodes (6%) of grade 1-2 asthenia, respectively, were reported. Four (12%) patients developed grade 1-2 anemia and two (6%) subjects suffered grade 3 anemia. Seven (21%) patients had grade 1-2 neutropenia and one (3%) presented grade 5 neutropenia. In 33 patients evaluable for activity of the 35 subjects included in the study; one (2.8%) presented a partial response; nine (25.7%) had stable disease, and 23 (65.7%) exhibited disease progression. Median time to progression and overall survival were 54 (12-210) and 70 (12-324) days, respectively. Intravenous topotecan at that dose and administration schedule displays scant activity in terms of response rate in individuals with advanced NSCLC previously treated with platinum and taxanes.

    Full Text Available Background: Gefitinib, an epidermal growth factor receptor-tyrosine kinase inhibitor, represents a new treatment option for patients with advanced non-small-cell lung cancer (NSCLC. We analyzed the data of patients who received Gefitinib for NSCLC in a tertiary care center in South India. Materials and Methods: Sixty-three patients with advanced NSCLC who had received Gefitinib either after failure of conventional chemotherapy or were previously not treated as they were unfit or unwilling for conventional treatment were included in the analysis. Results: The median follow-up for the cohort was 311 days (range 11-1544 days. Median time to progression was 161 (range 9-883 days. Complete and partial remission was seen in 1 (2% and 6 (9% patients, respectively, with overall response rate of 11%. Twenty-four (38% patients had stable disease. Gefitinib was well tolerated with no significant side effects. Conclusion: Gefitinib shows anti-tumor activity in pretreated or previously untreated patients with advanced NSCLC. It has a favorable toxicity profile and is well tolerated. Gefitinib should be considered as a viable therapy in patients with NSCLC.

    Full Text Available Lung cancer is the most common form of cancer with the highest incidence worldwide. The mortality rates are highest in males and second highest in females, after breast cancer. The genetic predisposition to Non Small Cell Lung Cancer (NSCLC is still under investigation, however, studies have shown that the Epidermal Growth Factor Receptor (EGFR, a receptor tyrosine kinase is frequently over-expressed and activated to a phosphorylated state in NSCLC. The activity of EGFR in cancer cells results in the phosphorylation of downstream proteins that promote cell proliferation, invasion, metastasis, and inhibition of apoptosis. Targeting the EGFR pathway therefore constitutes a relevant strategy for cancer therapy. Gefitinib is a selective inhibitor of the EGFR tyrosine kinase and is indicated for the treatment of adult patients with locally advanced or metastatic NSCLC with activating mutations of EGFR-TK. From the pharmacoeconomic point of view gefitinib is dominant (more effective and less expensive compared to the alternatives. In conclusion, gefitinib is a treatment option for NSCLC tumors with a high clinical and economic value in the Italian setting.

We defined elderly as over the age of 70.Results: The population is ageing dramatically throughout most of the world. Given that situation, clinicians are seeing and being asked to treat more elderly patients that have NSCLC. Elderly patients are less likely to participate or be allowed to participate in prospective or retrospective studies of treatments for NSCLC. Elderly patients are also less likely to be staged appropriately for their advanced tumors, and are less likely to be referred for surgery or adjuvant therapy after surgery. When treatment is tailored to patient comorbidities but not to age, the data support survival and outcomes comparable to those of younger patients.Conclusions: Data are limited on the treatment of elderly patients with NSCLC. No data exist to support limiting recommendations for treatment based on age alone. Treatments should be determined on an individual basis.Keywords: thoracic surgery, radiation therapy, chemotherapy, pulmonary, physiology, ageing, SBRT

    Prognosis for non-small cell lung cancer (NSCLC) patients who have locally advanced unresectable disease is poor for persistent thoracic disease and development of distant metastasis. In view of the poor rate of local control following conventional radiation therapy, there is a great need for methods to improve its efficacy. Three-dimensional conformal radiation therapy (3DCRT) is a high precision radiotherapy able to deliver higher doses with smaller doses to the surrounding normal tissues. However, the real problem is: "what do I want to treat?" This question is addressed based on the clinical and biological target volume definition. Selection of the CTV is therefore basically the clinical compromise between the most radical possible CTV and the critical normal tissue tolerance. The clinical target volume includes the GTV plus a margin to encompass subclinical or microscopic malignant disease immediately adjacent to it. Standard radiation therapy consists of a dose of 40 Gy to the entire mediastinum, supraclavicular fossa, and ipsilateral hilum, even if there is no evidence of disease in these areas. Despite the high risk of nodal spread in lung cancer, the benefit of additional elective nodal irradiation (ENI) is not proven while it seems to significantly increase the rate of radiation morbidity. Several studies have been published where ENI was systematically omitted. The main arguments for omitting ENI and the principal clinical experiences, are discussed. PMID:15018317

Non-small-cell lung cancer (NSCLC is the main pathological type of lung cancer, and most newly diagnosed NSCLC patients cannot undergo surgery because the disease is already locally advanced or metastatic. Despite chemoradiotherapy and targeted therapy improving clinical outcomes, overall survival remains poor. Immune checkpoint blockade, especially blockade of programmed death-1 (PD-1 receptor and its ligand PD-L1, achieved robust responses and improved survival for patients with locally advanced/metastatic NSCLC in preclinical and clinical studies. However, with regard to PD-1/PD-L1 checkpoint blockade as monotherapy or in combination with other antitumor therapies, such as chemotherapy, radiotherapy (including conventional irradiation and stereotactic body radiotherapy, and target therapy, there are still many unknowns in treating patients with NSCLC. Despite this limited understanding, checkpoint blockade as a novel therapeutic approach may change the treatment paradigm of NSCLC in the future. Here we review the main results from completed and ongoing studies to investigate the feasibility of PD-1/PD-L1 inhibitors, as monotherapy or combinatorial agents in patients with locally advanced and metastatic NSCLC, and explore optimal strategy in such patients.

    Full Text Available Miliary mottling on chest radiography is seen in miliary tuberculosis, certain fungal infections, sarcoidosis, coal miner’s pneumoconiosis, silicosis, hemosiderosis, fibrosing alveolitis, acute extrinsic allergic alveolitis, pulmonary eosinophilic syndrome, pulmonary alveolar proteinosis, and rarely in hematogenous metastases from the primary cancers of the thyroid, kidney, trophoblasts, and some sarcomas. Although very infrequent, miliary mottling can be seen in primary lung cancers. Herein, we report the case of a 28-year-old female with chest X-ray showing miliary mottling. Thoracic computed tomography (CT features were suggestive of tuberculoma with miliary tuberculosis. CT-guided fine needle aspiration cytology confirmed the diagnosis as lower-lobe, left lung non-small cell carcinoma (adenocarcinoma. It is rare for the non-small cell carcinoma of the lung to present as miliary mottling. The rarity of our case lies in the fact that a young, non-smoking female with miliary mottling was diagnosed with non-small cell carcinoma of the lung.

    Full Text Available Background and objective It has been proven that gefitinib produces only 10%-20% tumor regression in heavily pretreated, unselected non-small cell lung cancer (NSCLC patients as the second- and third-line setting. Asian, female, nonsmokers and adenocarcinoma are favorable factors; however, it is difficult to find a patient satisfying all the above clinical characteristics. The aim of this study is to identify novel predicting factors, and to explore the interactions between clinical variables and their impact on the survival of Chinese patients with advanced NSCLC who were heavily treated with gefitinib in the second- or third-line setting. Methods The clinical and follow-up data of 127 advanced NSCLC patients referred to the Cancer Hospital & Institute, Chinese Academy of Medical Sciences from March 2005 to March 2010 were analyzed. Multivariate analysis of progression-free survival (PFS was performed using recursive partitioning, which is referred to as the classification and regression tree (CART analysis. Results The median PFS of 127 eligible consecutive advanced NSCLC patients was 8.0 months (95%CI: 5.8-10.2. CART was performed with an initial split on first-line chemotherapy outcomes and a second split on patients’ age. Three terminal subgroups were formed. The median PFS of the three subsets ranged from 1.0 month (95%CI: 0.8-1.2 for those with progressive disease outcome after the first-line chemotherapy subgroup, 10 months (95%CI: 7.0-13.0 in patients with a partial response or stable disease in first-line chemotherapy and age <70, and 22.0 months for patients obtaining a partial response or stable disease in first-line chemotherapy at age 70-81 (95%CI: 3.8-40.1. Conclusion Partial response, stable disease in first-line chemotherapy and age ≥ 70 are closely correlated with long-term survival treated by gefitinib as a second- or third-line setting in advanced NSCLC. CART can be used to identify previously unappreciated patient

    Patients with advanced non-small-cell lung cancer (NSCLC) have a poor prognosis and high mortality. The therapeutic improvement caused by the new generation of cytotoxic agents seems to have reached a plateau. The main categories of targeted therapeutics applicable for NSCLC include receptor-targeted therapy, signal transduction or cell-cycle inhibition, angiogenesis inhibitors, gene therapy, and vaccines. Several major classes of agents directed at specific cellular mechanisms exist for the treatment of NSCLC. The anti-epidermal growth factor receptor (EGFR) group contains trastuzumab and IMC-C225, monoclonal antibodies against EGFRs that are overexpressed in many cancers. OSI-774 and ZD1839 are inhibitors of EGFR tyrosine kinase, a key enzyme of the signaling pathway. Farnesyl transferase inhibitors, such as SCH66336, and protein kinase C inhibitors, such as ISIS 3521, have also shown antitumor activity. Antiangiogenesis agents that have shown promise include TNP-470, recombinant endostatin, and angiostatin. Antibodies to vascular endothelial growth factor (VEGF) also seem to control tumor progression and may prolong survival. LY317615, an inhibitor of protein kinase Cb, augmented the tumor growth delay produced by cytotoxic drugs. All of these agents are in different phases of clinical testing and have shown encouraging activity as single agents or in combination with chemotherapy drugs. These new agents are more target specific, less toxic, easier to administer, and may lead to enhanced safety and survival for patients with advanced NSCLC. PMID:14720353

    Objective: To evaluate the clinical significance of telomerase activity particularly in terms of prognostic impact in non-small cell lung cancer (NSCLC). Methods: The exfoliated cells from fibrobronchoscopic brushing were studied using polymerase chain reaction based on a telomerase repeat amplification protocal assay. Samples were taken from 60 NSCLC and 20 pulmonary infection cases. Results: Telomerase activity was detected in 53 of 60(88.3%) NSCLC specimens from the lesion side and in 5 of 25(20.0%) from the contralateral side but only in 2 of 20 pulmonary infection samples (P<0.05). The telomerase activity levels in NSCLC (medium 0.109) were significantly higher than those in pulmonary infection (medium 0.018, U=4.95, P<0.05). The telomerase activity levels in tumor staged IIIb-IV (medium 0.173) were higher than those in staged I-IIIa (medium 0.132, U=1.899, P<0.05). Conclusion: Telomerase activity is one of the most important marker in patients with NSCLC. Telomerase activity increases with the advance of tumor stage and can be used as a prognostic indicator of advanced NSCLC.

    Full Text Available Background: Single nucleotide polymorphisms (SNPs in the DNA repair genes are suspected to be related to the survival of lung cancer patients due to their possible influence on DNA repair capacity (DRC. However, the study results are inconsistent. Methods: A follow-up study of 610 non-small cell lung cancer (NSCLC patients was conducted to investigate genetic polymorphisms associated with the DNA repair genes in relation to NSCLC survival; 6 SNPs were genotyped, including XRCC1 (rs25487 G>A, hOGG1 (rs1052133 C>G, MUTYH (rs3219489 G>C, XPA (rs1800975 G>A, ERCC2 (rs1799793 G>A and XRCC3 (rs861539 C>T. Kaplan-Meier survival curve and Cox proportional hazards regression analyses were performed. SNP-SNP interaction was also examined using the survival tree analysis. Results: Advanced disease stage and older age at diagnosis were associated with poor prognosis of NSCLC. Patients with the variant ‘G' allele of hOGG1 rs1052133 had poor overall survival compared with those with the homozygous wild ‘CC' genotype, especially in female patients, adenocarcinoma histology, early stage, light smokers and without family history of cancer. For never smoking female lung cancer patients, individuals carrying homozygous variant ‘AA' genotype of XPA had shorter survival time compared to those with wild ‘G' alleles. Furthermore, females carrying homozygous variant XPA and hOGG1 genotypes simultaneously had 2.78-fold increased risk for death. Among all 6 polymorphisms, the homozygous variant ‘AA' of XPA carriers had poor prognosis compared to the carriers of wild ‘G' alleles of XPA together with other base excision repair (BER polymorphisms. Conclusions: Besides disease stage and age, the study found DNA repair gene polymorphisms were associated with lung cancer survival.

    Highlights: •The patients underwent the second FDG PET during the early stage of concurrent chemoradiotherapy (CCRT). •To our knowledge, this could be the first study showing that the repeated FDG PET during the early stage of CCRT has added value by being a prognostic factor for recurrence of the locally advanced NSCLC patients. •This is a result of continuous research. •The decrease of MTV was the only significant risk factor for recurrence. -- Abstract: Purpose: The aim of this study is to investigate the value of [{sup 18}F] fluorodeoxyglucose positron emission tomography/computed tomography ({sup 18}F FDG PET/CT) to predict recurrence of patients with locally advanced non-small cell lung cancer (NSCLC) during the early stage of concurrent chemoradiotherapy (CCRT). Methods: A total of 53 stage III NSCLC patients without diabetics or undergoing surgery were enrolled in the prospective study. Those patients were evaluated by FDG PET before and following 40 Gy radiotherapy (RT) with a concurrent cisplatin-based heterogeneous chemotherapy regimen. Semiquantitative assessment was used to determine maximum and mean SUVs (SUVmax/SUVmean) and metabolic tumor volume (MTV) of the primary tumor. The prognostic significance of PET/CT parameters and other clinical variables was assessed using Cox regression analyses. The cutoffs of PET/CT parameters which have been determined by the previous study were used to separate the groups with Kaplan–Meier curves. Results: Recurrence rates at 1- and 2-years were 18.9% (10/53) and 50.9% (27/53) for all patients, respectively. Cox regression analysis showed that the only prognostic factor for recurrence was a decrease of MTV. Using the cutoff of 29.7%, a decrease of MTV can separate the patients into 2 groups with Kaplan–Meier curve successfully. Conclusion: The prospective study has reinforced the early predictive value of MTV in repeated {sup 18}F-FDG PET/CT for recurrence in a subgroup of locally advanced NSCLC who

    Objective: To evaluate the efficacy and safety of celecoxib plus platinum-doublet as first-line chemotherapy in treatment of advanced non-small cell lung cancer (NSCLC), and to determine the subgroup benefiting from celecoxib combined therapy by molecular analysis. Methods: A total of 44 treatment-naive patients of advanced NSCLC with positive cyclooxygenase-2 (COX-2) expression confirmed by immunohistochemical (IHC) staining were designed to receive celecoxib plus platinum-doublet chemotherapy (cisplatin plus gemcitabine, novelbine or docetaxol) from February 2005 to May 2007. On 5(7 day before chemotherapy, 400 mg celecoxib was administered twice a day orally until obvious evidence of disease progression or intolerable toxicity was found. Adverse events were recorded according to NCI-CTC criteria. The primary endpoint was overall survival (OS). The secondary endpoints included progression-free survival (PFS), 1-year survival rate, response rate (RR) and safety. Additionally, we detected epithelial growth factor receptor (EGFR) status including EGFR gene amplification by real-time PCR and gene mutations by DHPLC followed by sequencing. Results: The response rate was 45% (20/44), and the disease control rate (DCR) was 59% (26/44). The median progression-free survival time and median survival time were 6 m and 18 m, respectively. The 1-year survival rate was 68%. Chemotherapy cycle numbers and best response were found to be the predictive factors for PFS by COX model analysis (P=0.023 and P=0.000, respectively). No factor was found to affect OS. The most common toxicities included neutropenia and nausea/vomit. EGFR gene amplification was an independent prognostic factor influencing OS (P=0.0002). Patients with EGFR mutations (exon 21) had a tendency of disease progression (P=0.041). Conclusion: Encouraging activities of celecoxib combined with platinum-doublet chemotherapy were demonstrated in treatment-naive patients with advanced NSCLC, with good tolerances. For

  15. High-dose accelerated hypofractionated three-dimensional conformal radiotherapy (at 3 Gy/fraction) with concurrent vinorelbine and carboplatin chemotherapy in locally advanced non-small-cell lung cancer: a feasibility study

    International Nuclear Information System (INIS)

    Increasing the radiotherapy dose can result in improved local control for non-small-cell lung cancer (NSCLC) and can thereby improve survival. Accelerated hypofractionated radiotherapy can expose tumors to a high dose of radiation in a short period of time, but the optimal treatment regimen remains unclear. The purpose of this study was to evaluate the feasibility of utilizing high-dose accelerated hypofractionated three-dimensional conformal radiotherapy (at 3 Gy/fraction) with concurrent vinorelbine (NVB) and carboplatin (CBP) chemotherapy for the treatment of local advanced NSCLC. Untreated patients with unresectable stage IIIA/IIIB NSCLC or patients with a recurrence of NSCLC received accelerated hypofractionated three-dimensional conformal radiotherapy. The total dose was greater than or equal to 60 Gy. The accelerated hypofractionated radiotherapy was conducted once daily at 3 Gy/fraction with 5 fractions per week, and the radiotherapy was completed in 5 weeks. In addition to radiotherapy, the patients also received at least 1 cycle of a concurrent two-drug chemotherapy regimen of NVB and CBP. A total of 26 patients (19 previously untreated cases and 7 cases of recurrent disease) received 60Gy-75Gy radiotherapy with concurrent chemotherapy. All of the patients underwent evaluations for toxicity and preliminary therapeutic efficacy. There were no treatment-related deaths within the entire patient group. The major acute adverse reactions were radiation esophagitis (88.5%) and radiation pneumonitis (42.3%). The percentages of grade III acute radiation esophagitis and grade III radiation pneumonitis were 15.4% and 7.7%, respectively. Hematological toxicities were common and did not significantly affect the implementation of chemoradiotherapy after supportive treatment. Two patients received high dose of 75 Gy had grade III late esophageal toxicity, and none had grade IV and above. Grade III and above late lung toxicity did not occur. High-dose accelerated

    2001-01-01

    Objective: To analyse the microsatellite instability (MI) and loss of heterozygosity (LOH) in non-small cell lung cancer (NSCLC). Methods: MI and LOH at chromosome 17 were checked in 35 cases of NSCLC tumor-normal paired tissues using four microsatellite markers TP53 (17p13.1), THRA1 (17q11.2-12), D17S579 (17q12-21) and D17S855 (17q21) by PCR based analysis. Mutations of P53 exons 5-8 were also tested using PCR-single strand conformation polymorphism (PCR-SSCP) and PCR-denaturing gradient gel electrophoresis (PCR-DGGE) analysis. Results: 22 of 35 tumors (62.8%) displayed MI or LOH. 14 tumors (40.0%) exhibited MI, 11 tumors (31.4%) exhibited LOH, while 3 tumors (8.6%) exhibited MI and LOH concurrently. 23 tumors (65.7%) exhibited P53 gene mutations. The frequency of MI or LOH was obviously higher in the early-stage (stages I and II, 78.9%) than in the advanced-stage (stage III, 43.8%). However, the frequency of MI or LOH had no difference either between high-grade (75.0%) and low-grade (52.6%) differentiated NSCLC or between the tumors with P53 mutations (59.1%) and those without P53 mutations (69.2%). No relationship was observed between the presence of MI or LOH and the histologic subtype of NSCLC. Conclusion: The results suggest that MI and LOH at chromosome 17 may play a alterations on chromosome 17 in tumors of non-small cell lung cancer (NSCLC). In addition, studies reported contradictory results concerning the incidence of these alterations and the relationship between these genetic alterations and the clinical behavior of NSCLC. The aim of this study was to investigate the incidence of MI and LOH at chromosome 17 in tumors of patients with NSCLC and its association with clinical and histologic features of NSCLC.

    Lung cancer is a leading cause of cancer-related mortality across the world and tobacco smoking is the major risk factor. The Wnt signaling pathway is known to be involved in smoke-induced tumorigenesis in the lung. Promoter hypermethylation of Wnt inhibitory factor 1 (Wif1) has become a common event in a number of human tumors. Using a methylation-specific PCR, hypermethylation of the Wif1 gene promoter was evaluated in 139 primary non-small cell lung cancers (NSCLCs) and its correlation wit...

    [EN] Lung cancer is the leading cause of cancer-related death worldwide, and is the third most common cancer type; it can be classified into two subgroups based on histology: non-small-cell lung cancer (NSCLC) and small-cell lung cancer (SCLC). The 5-year survival still remains poor and despite the existence of several distinct tumour phenotypes, therapeutic decisions are mainly based on clinical features such as stage or performance status. This highlights the need for new diagnostic and pro...

    Full Text Available TERT is of great importance in cancer initiation and progression. Many studies have demonstrated the TERT polymorphisms as risk factors for many cancer types, including lung cancer. However, the impacts of TERT variants on cancer progression and treatment efficacy have remained controversial. This study aimed to investigate the association of TERT polymorphisms with clinical outcome of advanced non-small cell lung cancer (NSCLC patients receiving first-line platinum-based chemotherapy, including response rate, clinical benefit, progression-free survival (PFS, overall survival (OS, and grade 3 or 4 toxicity. Seven polymorphisms of TERT were assessed, and a total of 1004 inoperable advanced NSCLC patients treated with platinum-based chemotherapy were enrolled. It is exhibited that the variant heterozygote of rs4975605 showed significant association with a low rate of clinical benefit, and displayed a much stronger effect in never-smoking female subset, leading to the clinical benefit rate decreased from 82.9% (C/C genotype to 56.4% (C/A genotype; adjusted OR, 3.58; P=1.40×10(-4. It is also observed that the polymorphism rs2736109 showed significant correlation with PFS (log-rank P=0.023. In age > 58 subgroup, patients carrying the heterozygous genotype had a longer median PFS than those carrying the wild-type genotypes (P=0.002. The results from the current study, for the first time to our knowledge, provide suggestive evidence of an effect of TERT polymorphisms on disease progression variability among Chinese patients with platinum-treated advanced NSCLC.

    Objective: In the present study, we have examined the safety and efficacy of recombinant adenovirus encoding human p53 tumor suppressor gene (rAd-p53) injection in patients with advanced non-small-cell lung cancer (NSCLC) in the combination with the therapy of bronchial arterial infusion (BAI). Methods: A total of 58 patients with advanced NSCLC were enrolled in a non-randomized, two-armed clinical trial. Of which, 19 received a combination treatment of BAI and rAd-p53 (the combo group), while the remaining 39 were treated with only BAI (the control group). Patients were followed up for 12 months, with safety and local response evaluated by the National Cancer Institute's Common Toxicity Criteria and response evaluation criteria in solid tumor (RECIST), respectively. Time to progression (TTP) and survival rates were also analyzed by Kaplan-Meier method. Results: In the combo group,19 patients received a total of 49 injections of rAd-p53 and 46 times of BAI, respectively, while 39 patients in the control group received a total of 113 times of BAI. The combination treatment was found to have less adverse events such as anorexia, nausea and emesis, pain, and leucopenia (P0.05). Patients in the combo group had a longer TTP than those in the control group (a median 7.75 vs 5.5 months, P=0.018). However, the combination treatment did not lead to better survival, with survival rates at 3, 6, and 12 months in the combo group being 94.74%, 89.47%, and 52.63%, respectively, com-pared with 92.31%, 69.23%, and 38.83% in the control group (P=0.224). Conclusion: Our results show that the combination of rAd-p53 and BAI was well tolerated in patients with NSCLC and may have improved the quality of life and delayed the disease progression. A further study to better determine the efficacy of this combination therapy is warranted.

    Objective:XRCC1 polymorphism is a research hotpot in individual treatment for non-small cell lung cancer (NSCLC).To obtain the association between XRCC1 polymorphism and clinical outcome of platinum-based treatment for NSCLC,a meta-analysis was conducted.Methods:Databases including PubMed,Embase,Cochrane,and Chinese National Knowledge Infrastructure (CNKI) were searched for publications that met the inclusion criteria.A fixed effect model was used to estimate pooled odds ratio (OR) and hazard ratio (HR) with 95% confidence interval (CI) for the association between XRCC1 Arg399Gln and response or survival of platinum-based treatment for advanced NSCLC.A chi-squared-based Q-test was used to test the heterogeneity hypothesis.Egger's test was used to check publication bias.Results:Seventeen published case-control studies that focus on the association between XRCC1 Arg399GIn and response or survival of platinum-based treatment for advanced NSCLC in 2 256 subjects were included in this meta-analysis,of whom 522 were AA genotypes (23.2% frequency),916 AG genotypes (40.6% frequency),and 818 GG genotypes (36.2% frequency).The overall response rate (ORR) was 45.2% (110/243) for AA genotype patients,29.9% for AG genotype (73/244),and 30.7% for GG genotype (124/403).The heterogeneity test did not show any heterogeneity and the Egger's test did not reveal an obvious publication bias among the included studies.The meta-analysis indicated that AA genotype patients presented higher response rates toward platinum drug treatment compared with G model (GG+GA) patients (GG vs.AA model:OR=0.489,95% CI 0.266-0.900,P=0.021;AG vs.AA model:OR=0.608,95% CI 0.392-0.941,P=0.026; GA+AA vs.GG model:OR=1.259,95% CI 0.931-1.701,P=0.135; GG+GA vs.AA model:OR=0.455,95% CI 0.313-0.663,P=0.0001).However,no evidence validates XRCC1 associates with the survival following platinum drug therapy.Conclusions:Our meta-analysis suggested that XRCC1 Arg399GIn is related with the

    In the last few years, the introduction of novel immunotherapeutic agents has represented a treatment shift for a subset of patients with non-small-cell lung cancer (NSCLC). Checkpoint inhibitors have been demonstrated to improve survival in advanced stage disease with very good tolerability. This success follows many years of scientific effort to manipulate the human immune system to attack cancer cells. With a variety of approaches ranging from vaccines to administration of interleukin or interferon-γ, the results in NSCLC were unsuccessful, with the view that it is a scarcely immunogenic cancer, unlike melanoma or renal cell carcinoma. The step change has come from understanding of immune checkpoints-cell surface molecules that regulate immune system activation and mediate coinhibitory signaling pathways that physiologically protect the body from autoimmunity. These pathways play an important role in tumors, including NSCLC, and are a mechanism of escape from immune surveillance. Several monoclonal antibodies have been developed in order to inhibit these molecules and unleash the brakes of the immune system. Currently in NSCLC, 7 different checkpoint inhibitors are under investigation: 2 anti-cytotoxic T-lymphocyte-associated antigen 4, 2 anti-programmed death (PD)-1, and 3 anti-PD-ligand 1 antibodies. Here we review the progress to date in developing immunotherapy for NSCLC, summarize results from published trials, highlight ongoing trials, and discuss progress in the question of how best to select patients for this treatment.

    Of the numerous oncogenes implicated in human cancer, the most common and perhaps the most elusive to target pharmacologically is RAS. Since the discovery of RAS in the 1960s, numerous studies have elucidated the mechanism of activity, regulation, and intracellular trafficking of the RAS gene products, and of its regulatory pathways. These pathways yielded druggable targets, such as farnesyltransferase, during the 1980s to 1990s. Unfortunately, early clinical trials investigating farnesyltransferase inhibitors yielded disappointing results, and subsequent interest by pharmaceutical companies in targeting RAS waned. However, recent advances including the identification of novel regulatory enzymes (e.g., Rce1, Icmt, Pdeδ), siRNA-based synthetic lethality screens, and fragment-based small-molecule screens, have resulted in a "Ras renaissance," signified by new Ras and Ras pathway-targeted therapies that have led to new clinical trials of patients with Ras-driven cancers. This review gives an overview of KRas signaling pathways with an emphasis on novel targets and targeted therapies, using non-small cell lung cancer as a case example.

    The recent approval of two PD-1 inhibitors for the treatment of non-small cell lung cancer (NSCLC) has rapidly led to the widespread use of these agents in oncology practices. Pneumonitis has been recognized as a potentially life-threatening adverse event among NSCLC patients treated with PD-1 inhibitors; however, the detailed clinical and radiographic manifestations of this entity remain to be described. We report on two cases of anti-PD-1 pneumonitis in advanced NSCLC patients treated with nivolumab after its FDA approval. Both patients presented with ground-glass and reticular opacities and consolidations in a peripheral distribution on CT, demonstrating a radiographic pattern of cryptogenic organizing pneumonia. Consolidations were extensive and rapidly developed within 8 weeks of therapy in both cases. Both patients were treated with corticosteroids with subsequent improvement of respiratory symptoms and radiographic findings. One patient experienced recurrent pneumonitis after completing corticosteroid taper, or a "pneumonitis flare," in the absence of nivolumab retreatment, with subsequent improvement upon corticosteroid readministration. With the increasing use of immune checkpoint inhibitors in a growing number of tumor types, awareness of the radiographic and clinical manifestations of PD-1 inhibitor-related pneumonitis will be critical for the prompt diagnosis and management of this potentially serious adverse event.

    The prognostic indicators for synchronous multiple primary non-small cell lung cancer (NSCLC) vary across reports. In present study, the prognostic factors for the patients with synchronous multiple primary NSCLC were analyzed in a large cohort. A total of 285 patients with synchronous multiple primary NSCLC who underwent radical surgical resection and with complete follow-up information were included in this study. The Kaplan-Meier method were used for survival analysis, Cox proportional hazards regression models were used for risk factors evaluation. Among them, 94 (33.0%) patients had bilateral tumors and 51 (17.9%) had multiple (≥3) tumors. The 5-year disease-free survival (DFS) and overall survival (OS) rate was 58.7% and 77.6%, respectively. Univariate analysis identified parameters conferring shorter OS including male gender, symptomatic disease, negative family history, large maximal tumor size, not all adenocarcinomas, advanced highest T stage, and lymph node involvement. Multivariate analysis showed that male gender (p = 0.020), symptomatic disease (p = 0.017), and lymph node involvement (p involvement (p = 0.002) were the independent unfavorable prognosticators. In conclusion, we identified independent prognosticators which will provide the valuable clues for postoperative management of patients with synchronous multiple primary NSCLC. PMID:27254665

    Activating somatic mutations of the tyrosine kinase domain of epidermal growth factor receptor (EGFR) have recently been characterized in a subset of patients with advanced non-small cell lung cancer (NSCLC). Patients harboring these mutations in their tumors show excellent response to EGFR...... tyrosine kinase inhibitors (EGFR-TKIs). The EGFR-TKI gefitinib has been approved in Europe for the treatment of adult patients with locally advanced or metastatic NSCLC with activating mutations of the EGFR TK. Because EGFR mutation testing is not yet well established across Europe, biomarker......-directed therapy only slowly emerges for the subset of NSCLC patients most likely to benefit: those with EGFR mutations....

Methods 33 patients with histologically confirmed NSCLC were enrolled in a combined radiochemotherapy protocol. 29 patients were assessable for evaluation of toxicity and tumor response. Treatment included two cycles of induction chemotherapy with gemcitabine (1200 mg/m2 and vinorelbine (30 mg/m2 at day 1, 8 and 22, 29 followed by concurrent radiotherapy (2.0 Gy/d; total dose 66.0 Gy and chemotherapy with gemcitabine every two weeks at day 43, 57 and 71. Radiotherapy planning included [18F] fluorodeoxyglucose positron emission tomography (FDG PET based target volume definition. 10 patients were included in the phase I study with an initial gemcitabine dose of 300 mg/m2. The dose of gemcitabine was increased in steps of 100 mg/m2 until the MTD was realized. Results MTD was defined for the patient group receiving gemcitabine 500 mg/m2 due to grade 2 (next to grade 3 esophagitis in all patients resulting in a mean body weight loss of 5 kg (SD = 1.4 kg, representing 8% of the initial weight.

    Full Text Available Abstract Background In recent years, maintenance chemotherapy is increasingly being recognized as a new treatment strategy to improve the outcome of advanced non-small cell lung cancer (NSCLC. However, the optimal maintenance strategy is still controversial. Gemcitabine is a promising candidate for single-agent maintenance therapy because of little toxicity and good tolerability. We have conducted a randomized phase II study to evaluate the validity of single-agent maintenance chemotherapy of gemcitabine and to compare continuation- and switch-maintenance. Methods Chemonaïve patients with stage IIIB/IV NSCLC were randomly assigned 1:1 to either arm A or B. Patients received paclitaxel (200 mg/m2, day 1 plus carboplatin (AUC 6 mg/mL/min, day 1 every 3 weeks in arm A, or gemcitabine (1000 mg/m2, days 1 and 8 plus carboplatin (AUC 5 mg/mL/min, day1 every 3 weeks in arm B. Non-progressive patients following 3 cycles of induction chemotherapy received maintenance gemcitabine (1000 mg/m2, days 1 and 8 every 3 weeks. (Trial registration: UMIN000008252 Results The study was stopped because of delayed accrual at interim analysis. Of the randomly assigned 50 patients, 49 except for one in arm B were evaluable.

    2008-01-01

    A platinum-based doublet with a third-generation agent represents the standard first-line treatment for advanced non-small cell lung cancer patients with good performance status (PS). Traditional chemotherapy provides response rates of 20 %-40 % and a median survival of 8-10 months. In an attempt to improve its outcome, alternative schedules have been proposed, namely sequential, alternating, and maintenance therapy. Sequential chemotherapy with a platinum-based doublet followed by a single agent is feasible in patients with good PS; The use of sequential single agents is an option for elderly and frail patients unsuitable for a platinum-based combination. Based on trials published so far, it is unlikely that an alternating chemotherapy strategy will be proved superior to standard chemotherapy in patients with good PS.Consolidation chemotherapy may provide additional benefit for patients achieving disease control after standard first-line chemotherapy.%含铂的两药联合化疗仍然是PS0-1分晚期非小细胞肺癌(NSCLC)患者的一线标准治疗方案,晚期NSCLC一线治疗的缓解率仅为20%~40%,中位生存时间为8~10个月.为了提高治疗的疗效,不同方案组合化疗成为研究的热点,主要包括序贯化疗、轮替化疗和巩固化疗.对于PS0~1分、能耐受毒副反应的患者,临床医师可以考虑含铂的联合化疗方案随后单药治疗.对于年龄较大、身体情况较差不能耐受含铂化疗的患者,临床医师可以考虑单药治疗随后用单药治疗的序贯给药方式.迄今为止没有一个临床试验可以证实交替化疗比标准化疗疗效好.在标准的4~6个周期一线化疗后,在能耐受毒副反应的情况下,巩固化疗可能为患者提高生存质量.

    Purpose: Patients treated with chemoradiotherapy for locally advanced non-small-cell lung carcinoma (LA-NSCLC) were analyzed for local-regional failure (LRF) and overall survival (OS) with respect to radiotherapy dose intensity. Methods and Materials: This study combined data from seven Radiation Therapy Oncology Group (RTOG) trials in which chemoradiotherapy was used for LA-NSCLC: RTOG 88-08 (chemoradiation arm only), 90-15, 91-06, 92-04, 93-09 (nonoperative arm only), 94-10, and 98-01. The radiotherapeutic biologically effective dose (BED) received by each individual patient was calculated, as was the overall treatment time-adjusted BED (tBED) using standard formulae. Heterogeneity testing was done with chi-squared statistics, and weighted pooled hazard ratio estimates were used. Cox and Fine and Gray's proportional hazard models were used for OS and LRF, respectively, to test the associations between BED and tBED adjusted for other covariates. Results: A total of 1,356 patients were analyzed for BED (1,348 for tBED). The 2-year and 5-year OS rates were 38% and 15%, respectively. The 2-year and 5-year LRF rates were 46% and 52%, respectively. The BED (and tBED) were highly significantly associated with both OS and LRF, with or without adjustment for other covariates on multivariate analysis (p < 0.0001). A 1-Gy BED increase in radiotherapy dose intensity was statistically significantly associated with approximately 4% relative improvement in survival; this is another way of expressing the finding that the pool-adjusted hazard ratio for survival as a function of BED was 0.96. Similarly, a 1-Gy tBED increase in radiotherapy dose intensity was statistically significantly associated with approximately 3% relative improvement in local-regional control; this is another way of expressing the finding that the pool-adjusted hazard ratio as a function of tBED was 0.97. Conclusions: Higher radiotherapy dose intensity is associated with improved local-regional control

    The phamacogenetics is being used to predict whether the selected chemotherapy will be really effective and tolerable to the patient. Irinotecan, oxidized by CYP3A4 to produce inactive compounds, is used for treatment of various cancers including advanced non small cell lung cancer (NSCLC) patients. CYP3A4*16B polymorphism was associated with decreased metabolism ofirrinotecan. Irinotecan is also metabolized by carboxylesterase to its principal active metabolite, SN-38, which is subsequently glucuronidated by UGT1As to form the inactive compound SN-38G. UGT1A1*28 and UGT1A1*6 polymorphisms were useful for predicting severe toxicity with NSCLC patients treated with irinotecan-based chemotherapy. Platinum-based compounds (cisplatin, carboplatin) are being used in combination with new cytotoxic drugs such as gemcitabine, paclitaxel, docetaxel, or vinorelbine in the treatment of advanced NSCLC. Cisplatin activity is mediated through the formation of cisplatin-DNA adducts. Gene polymorphisms of DNA repair factors are therefore obvious candidates for determinants of repair capacity and chemotherapy efficacy. ERCC1, XRCC1 and XRCC3 gene polymorphisms were a useful marker for predicting better survival in advanced NSCLC patients treated with platinum-based chemotherapy. XPA and XPD polymorphisms significantly increased response to platinum-based chemotherapy. These DNA repair gene polymorphisms were useful as a predictor of clinical outcome to the platinum-based chemotherapy. EGFR kinase inhibitors induce dramatic clinical responses in NSCLC patients with advanced disease. EGFR gene polymorphism in intron 1 contains a polymorphic single sequence dinudeotide repeat (CA-SSR) showed a statistically significant correlation with the gefitinib response and was appeared to be a useful predictive marker of the development of clinical outcome containing skin rashes with gefitinib treatment. The other polymorphisms of EGFR were also associated with increased EGFR promoter activity

    Brain metastasis, a common complication of non-small cell lung cancer (NSCLC) with an incidence rate of 30%-50%, significantly affects the patients' quality of life. The prognosis of patients of NSCLC with brain metastasis is extremely poor, the average median survival is only 1 m-2 m without treatment. The targeted therapy based on lung cancer driven gene is a new treatment. Besides, the immunotherapy which can enhance the effect of anti-cancer by simulating the immune system is a new approach. The combination of targeted therapy and immunotherapy can greatly benefit patients in clinical work. PMID:27561803

    A 68-year-old man developed progressive vertigo, saccadic eye movements, and tremors. Computed tomography showed multiple lung nodules. Surgery was performed and the pathological diagnosis was large cell neuroendocrine carcinoma in the left upper lobe with ipsilobar metastases, and adenocarcinoma in the left lower lobe. The neurological symptoms resolved dramatically after complete resection of the tumors. Opsoclonus-myoclonus syndrome associated with non-small-cell lung carcinoma is extremely rare. Surgery should not be delayed if a complete resection is expected.

  20. Afatinib for the treatment of metastatic non-small cell lung cancer

    International Nuclear Information System (INIS)

    Targeting the epidermal growth factor receptor (EGFR) in patients with non-small cell lung cancer (NSCLC) harboring sensitizing mutations in the tyrosine kinase (TKI) domain has led to a significant change in the management of this disease. The classic or sensitizing mutations are G719X mutation in exon 18, in-frame deletions or insertion of exon 19, L858R or L861Q mutation in exon 21. Approximately 90% of these mutations are exon 19 deletion or exon 21 L858R point mutation. Gefitinib and erlotinib are reversible first-generation inhibitors of mutant EGFR, and treatment with these agents in the first-line setting has demonstrated a progression-free survival of 9.5–13.7 months. However, the majority of these patients ultimately develop resistance to these drugs. Afatinib is an irreversible pan-ErbB inhibitor that was developed to circumvent the problem of resistance to first-generation TKIs. The LUX-Lung studies have evaluated the efficacy and toxicities of afatinib in treatment-naïve and refractory NSCLC patients. The promising results of some of these trials led to approval of afatinib by the US Food and Drug Administration for patients with advanced NSCLC and EGFR exon 19 deletions or exon 21 (L858R) substitution mutations. Afatinib causes toxicities similar to those of the first-generation EGFR TKIs, such as diarrhea, rash, acne, and stomatitis, and overall is well tolerated. This article focuses on the clinical studies of afatinib in patients with NSCLC

    Background The combination of cisplatin and vinorelbine is an evidence-supported regimen for adjuvant chemotherapy for treating non-small cell lung cancer (NSCLC).But this doublet has considerable toxicity and unfavorable tolerability,and results in poor compliance.The cisplatin and gemcitabine regimen is one of the most active and well-tolerated regimens against advanced NSCLC,but its toxicity and tolerability has not been adequately evaluated in the adjuvant setting.Methods From a lung cancer database we retrospectively reviewed NSCLC patients receiving adjuvant chemotherapy of cisplatin (75 mg/m2) and gemcitabine (1250 mg/m2) between January 2005 and December 2011.Postoperative demographics,compliance to adjuvant therapy and toxicity were retrieved from medical records.Results A total of 132 patients met the criteria and were included in the study,96 were male (72.7%) and 36 were female (27.3%).Median age was 60.5 years old,range 29-75 years,and 41.7% of patients were ≥65 years old.Overall,68.2%patients received all four planned cycles,and the cumulative dose delivered for gemcitabine was 8333 mg (83.3% of the planned dose) and cisplatin 248 mg (82.7% of the planned dose).There were no treatment-related deaths.Grade 3/4neutropenia developed in 47 patients (35.6%) and was the predominant hematologic toxicity.Common grade 3/4 nonhematologic toxicities were nausea/vomiting (22.0%),infection (12.3%),and febrile neutropenia (11.4%).Conclusion Cisplatin and gemcitabine are feasible for use in the adjuvant setting with a favorable toxicity profile and superior tolerability compared with published data on cisplatin and vinorelbine.

The application of next-generation genomic technologies has offered a more comprehensive look at the mutational landscape across the different subtypes of non-small cell lung cancer (NSCLC. A number of recurrent mutations such as TP53, KRAS, and epidermal growth factor receptor (EGFR have been identified in NSCLC. While targeted therapeutic successes have been demonstrated in the therapeutic targeting of EGFR and ALK, the majority of NSCLC tumors do not harbor these genomic events. This review looks at the current treatment paradigms for lung adenocarcinomas and squamous cell carcinomas, examining genomic aberrations that dictate therapy selection, as well as novel therapeutic strategies for tumors harboring mutations in KRAS, TP53, and LKB1 which, to date, have been considered “undruggable”. A more thorough understanding of the molecular alterations that govern NSCLC tumorigenesis, aided by next-generation sequencing, will lead to targeted therapeutic options expected to dramatically reduce the high mortality rate observed in lung cancer.

    Objective To identify potential serum biomarkers that could be used to discriminate lungcancers from normal. Methods Proteomic spectra of twenty-eight serum samples from patientswith non-small cell lung cancer and twelve from normal individuals were generated by SELDI(Surfaced Enhanced Laser Desorption/Ionization) Mass Spectrometry. Anion-exchange columns wereused to fractionate the sera into 6 designated pH groups. Two different types of protein chip arrays,IMAC-Cu and WCX2, were employed. Samples were examined in PBSII Protein Chip Reader(Ciphergen Biosystem Inc) and the discriminatory profiling between cancer and normal samples wasanalyzed with Biomarker Pattern software. Results Five distinct potential lung cancer biomarkerswith higher sensitivity and specificity were found, with four common biomarkers in both IMAC-Cuand WCX2 chip; the remaining biomarker occurred only in WCX2 chip. Two biomarkers wereup-regulated while three biomarkers were down-regulated in the serum samples from patients withnon-small cell lung cancer. The sensitivities provided by the individual biomarkers were 75%-96.43%and specificities were 75%-100%. Conclusions The preliminary results suggest that serum is acapable resource for detecting specific non-small cell lung cancer biomarkers. SELDI massspectrometry is a useful tool for the detection and identification of new potential biomarker ofnon-small cell lung cancer in serum.

    Despite convincing evidence that the principles of accelerated repopulation would open up additional therapeutic opportunities in the treatment of advanced-stage non-small cell lung cancer, this strategy has been generally underexplored. The implementation of accelerated radiotherapy schedules has been hampered by logistical barriers, concerns about acute toxicity, and the prioritization of integrating concurrent chemotherapy into the standard treatment platform. At present, it is unclear to what extent accelerated fractionation will influence future treatment paradigms in non-small cell lung cancer, although technical advances in radiotherapy, allowing higher dose delivery with reduced toxicity, could permit the development of more convenient and tolerable forms of accelerated schedules.

    Wingless-type protein (Wnt)/β-catenin pathway alterations in non-small cell lung cancer (NSCLC) are associated with poor prognosis and resistance. In 598 stage III-IV NSCLC patients receiving platinum-based chemotherapy at the MD Anderson Cancer Center (MDACC), we correlated survival with 441 host single-nucleotide polymorphisms (SNPs) in 50 Wnt pathway genes. We then assessed the most significant SNPs in 240 Mayo Clinic patients receiving platinum-based chemotherapy for advanced NSCLC, 127 MDACC patients receiving platinum-based adjuvant chemotherapy and 340 early stage MDACC patients undergoing surgery alone (cohorts 2-4). In multivariate analysis, survival correlates with SNPs for AXIN2 (rs11868547 and rs4541111, of which rs11868547 was assessed in cohorts 2-4), Wnt-5B (rs12819505), CXXC4 (rs4413407) and WIF-1 (rs10878232). Median survival was 19.7, 15.6 and 10.7 months for patients with 1, 2 and 3-5 unfavorable genotypes, respectively (P=3.8 × 10(-9)). Survival tree analysis classified patients into two groups (median survival time 11.3 vs 17.3 months, P=4.7 × 10(-8)). None of the SNPs achieved significance in cohorts 2-4; however, there was a trend in the same direction as cohort 1 for 3 of the SNPs. Using online databases, we found rs10878232 displayed expression quantitative trait loci correlation with the expression of LEMD3, a neighboring gene previously associated with NSCLC survival. In conclusion, results from cohort 1 provide further evidence for an important role for Wnt in NSCLC. Investigation of Wnt inhibitors in advanced NSCLC would be reasonable. Lack of an SNP association with outcome in cohorts 2-4 could be due to low statistical power, impact of patient heterogeneity or false-positive observations in cohort 1. PMID:24980784

    Because poor performance status (PS) is an independent prognostic factor in non-small cell lung cancer (NSCLC), PS scores are widely used by oncologists to make treatment decisions. Advanced NSCLC patients with an Eastern Cooperative Oncology Group PS of 2 have poor prognoses and are frequently excluded from clinical trials. This article reviews the efficacy and safety of pemetrexed in this patient group. We identified English-language literature (through March 2015) involving completed and ongoing studies through searches of PubMed, meeting abstracts, ClinicalTrials.gov and the European Clinical Trials Register; search terms included 'pemetrexed,' 'NSCLC' and 'PS2'. Only studies reporting ≥1 subset analysis of PS2 patients receiving pemetrexed were chosen. Our search identified a total of ten pemetrexed studies in PS2 patients. Eight studies included only chemonaive patients, one study included both chemonaive patients and patients with one prior chemotherapy regimen and one study included only patients with one prior regimen. In subset analyses in these studies, PS2 patients had worse outcomes than PS0-1 patients regardless of treatment. In a phase 3 study, chemonaive advanced NSCLC patients with PS2 receiving pemetrexed‑carboplatin versus pemetrexed experienced improved overall survival [hazard ratio (HR)=0.62; P=0.001], progression-free survival (HR=0.46; Pstudies, PS2 patients treated with pemetrexed plus carboplatin as first-line therapy had improved response rates and survival. Additional research on PS2 patients is needed.

  7. Quality of life after palliative radiotherapy in non-small cell lung cancer: a prospective study

    International Nuclear Information System (INIS)

    Purpose: The purpose of this study was to investigate changes in respiratory symptoms and quality of life (QoL) in patients with locally advanced and metastatic non-small cell lung cancer (NSCLC) receiving thoracic radiotherapy. Additionally, the correlation between the level of symptom relief and objective tumor response was investigated. Methods and Materials: Sixty-five patients were entered in this prospective study. The EORTC QLQ-C30 and EORTC QLQ-LC13 were used to investigate changes in QoL. Assessments were performed before radiotherapy and 2 weeks, 6 weeks, and 3 months after radiotherapy. Results: The QoL response rates were excellent for hemoptysis (79%); good for arm/shoulder pain (56%), chest wall pain (53%), and cough (49%); moderate for dyspnea (39%); and minimal for the general symptoms fatigue (22%) and appetite loss (11%). The QoL response rates for the five functioning scales of the QLQ-C30 varied from 35% for role functioning to 57% for emotional functioning. Global QoL improved in 37% of the cases. In general, there was a tendency for better palliation of symptoms and improvement of QoL among patients with an objective tumor response than among those without objective tumor response, which was statistically significant for dyspnea (p = 0.02) and social functioning (p = 0.04). Conclusions: This study confirms that conventional thoracic radiotherapy offers palliation of respiratory symptoms and improved QoL in a substantial proportion of patients with locally advanced and metastatic NSCLC. Tumor reduction is only one of the mechanisms by which palliation of symptoms and improvement of QoL is achieved

    Full Text Available Abstract Background CD44s is a cell adhesion molecule known to mediate cellular adhesion to the extracellular matrix, a prerequisite for tumor cell migration. CD44s plays an important role in invasion and metastasis of various cancers. In the present study, we sought to determine whether CD44s is involved in clinical outcomes of patients with resected non-small cell lung cancer (NSCLC. Methods Using immunohistochemical staining, we investigated CD44s protein expression using tissue array specimens from 159 patients with resected NSCLC (adenocarcinoma (AC; n = 82 and squamous cell carcinoma (SCC; n = 77. Additionally, the immunoreactivity of cyclooxygenase (COX-2 was also studied. The clinicopathological implications of these molecules were analyzed statistically. Results High CD44s expression was detected more frequently in NSCLC patients with SCC (66/72; 91.7% than in those with AC histology (P 0.001. Additionally, high CD44s expression was significant correlated with more advanced regional lymph node metastasis (P = 0.021. In multivariate analysis of survival in NSCLC patients with AC histology, significant predictors were lymph node metastasis status (P P = 0.046, and high CD44s expression (P = 0.014. For NSCLC patients with SCC histology, the significant predictor was a more advanced tumor stage (P = 0.015. No significant association was found between CD44s and clinical outcome (P = 0.311. Conclusions High CD44s expression was a negative prognostic marker with significance in patients with resected NSCLC, particularly those with AC histology, and was independent of tumor stage.

    Objective: To explore the expression and significance of heparanase in non-small cell lung cancer (NSCLC) regarding prognosis and clinicopathological parameters. Methods: The expression of heparanase was assessed using immunohistochemistry staining and Western blot in 122 paraffin-embedded specimens and 38 freshly taken tissues. The relationship between heparanase expression and the clinicopathological factors was analyzed by Chi-square test, multivariate analysis and Kaplan-Meier method. Results: In the immunoreactive cells, staining was mainly located in cytoplasma and membrane. Human heparanase was highly expressed in lung cancer tissue (78.7%, 96/122) while negative in epithelia of normal lung tissues. The level of heparanase was remarkably higher in NSCLC than that in normal tissue (P=0.043).Expression of heparanase significantly correlated with TNM stage (P=0.025), lymphatic metastasis (P=0.002) and vascular invasion (P=0.0003). The patients with positive heparanase expression had a significantly shorter survival than those with negative heparanase expression (P=0.0006). In multivariate analysis, only p-TNM stage, lymphatic metastasis and vascular invasion could be considered as prognostic factors. Conclusion: Elevated level of heparanase in human non-small cell lung cancer tissues correlates with the TNM stage, invasion, metastasis and prognosis. However, heparanase expression is not an independent prognostic factor.

    Lung cancer, the leading cause of cancer-related death, still lacks reliable biomarkers. Apurinic/apyrimidinic endonuclease 1/Ref-1 is a multifunctional protein involved in the base excision repair of DNA damaged by oxidative stress or alkylating compounds, as well as in the regulation of multiple transcription factors. To validate apurinic/apyrimidinic endonuclease 1/Ref-1 as a biomarker for prediction of lung cancer recurrence, we studied 42 patients who received curative resection and mediastinal lymph node dissection for stage I non-small-cell lung cancer. They were divided into 2 groups based on recurrence, and compared by immunohistochemistry staining of paraffin-embedded tissues and Western blot analysis. Immunohistochemical staining showed a significant difference between the cytoplasm and nucleus in patients who had a recurrence compared to those with nonrecurrent adenocarcinoma. In Western blot analysis, the recurrent adenocarcinoma group showed increased expression of apurinic/apyrimidinic endonuclease 1/Ref-1 in cytoplasm, nucleus, and in total. This indicates that apurinic/apyrimidinic endonuclease 1/Ref-1 is unregulated in recurrent stage I adenocarcinoma. For clinical application as a prognostic marker for non-small-cell lung cancer, further investigation into the role of apurinic/apyrimidinic endonuclease 1/Ref-1 in carcinogenesis is needed in an expanded prospective study.

    Recently, researchers have been increasingly finding coagulation disorders are commonly the first sign of malignancy. It has now been established that cancer development leads to an increased risk of thrombosis, and conversely, excessive activation of blood coagulation profoundly influences cancer progression. In patients with lung cancer, a sustained stimulation of blood coagulation takes place. Cancer cells trigger coagulation through expression of tissue factor, and affect coagulation through expression of thrombin, release of microparticles that augment coagulation and so on. Coagulation also facilitates tumour progression through release of platelet granule contents, inhibition of natural killer cells and recruitment of macrophages. Non-small cell lung cancer (NSCLC) accounts for about 80%-85% of all lung malignancies. In the present review, we summarized the newly updated data about the physiopathological mechanisms of various components of the clotting system in different stages of carcinogenesis in NSCLC.%近来研究越来越多地发现凝血功能紊乱通常是恶性肿瘤的首发迹象。现在已经证实,肿瘤导致血栓形成的风险增加,而凝血功能的过度激活也极大地影响肿瘤的进展。在肺癌患者中,存在着持续的凝血刺激。癌细胞通过组织因子(tissue factor, TF)的表达激活凝血功能;通过凝血酶的表达和促凝血微粒的释放等影响凝血功能。凝血功能也通过介导血小板释放其颗粒内容物、抑制自然杀伤细胞和募集巨噬细胞而促进肿瘤的进展。非小细胞肺癌(non-small cell lung cancer, NSCLC)占肺癌的80%-85%,本文就凝血系统各个组分在NSCLC发生发展中的病理生理学机制的最新研究进展进行综述。

    Purpose: The present retrospective study assessed the role of proton beam therapy (PBT) in the treatment of patients with Stage II or III non-small-cell lung cancer who were inoperable or ineligible for chemotherapy because of co-existing disease or refusal. Patients and Methods: Between November 2001 and July 2008, PBT was given to 35 patients (5 patients with Stage II, 12 with Stage IIIA, and 18 with Stage IIIB) whose median age was 70.3 years (range, 47.4-85.4). The median proton dose given was 78.3 Gy (range, 67.1-91.3) (relative biologic effectiveness). Results: Local progression-free survival for Stage II-III patients was 93.3% at 1 year and 65.9% at 2 years during a median observation period of 16.9 months. Four patients (11.4%) developed local recurrence, 13 (37.1%) developed regional recurrence, and 7 (20.0%) developed distant metastases. The progression-free survival rate for Stage II-III patients was 59.6% at 1 year and 29.2% at 2 years. The overall survival rate of Stage II-III patients was 81.8% at 1 year and 58.9% at 2 years. Grade 3 or greater toxicity was not observed. A total of 15 patients (42.9%) developed Grade 1 and 6 (17.1%) Grade 2 toxicity. Conclusion: PBT for Stage II-III non-small-cell lung cancer without chemotherapy resulted in good local control and low toxicity. PBT has a definite role in the treatment of patients with Stage II-III non-small-cell lung cancer who are unsuitable for surgery or chemotherapy.

    Non-small-cell lung cancer (NSCLC) is the commonest cancer worldwide but survival remains poor with a high risk of relapse, particularly after nonsurgical treatment. Hypoxia is present in a variety of solid tumours, including NSCLC. It is associated with treatment resistance and a poor prognosis, although when recognised may be amenable to different treatment strategies. Thus, noninvasive assessment of intratumoral hypoxia could be used to stratify patients for modification of subsequent treatment to improve tumour control. Molecular imaging approaches targeting hypoxic cells have shown some early success in the clinical setting. This review evaluates the evidence for hypoxia imaging using PET in NSCLC and explores its potential clinical utility. (orig.)

    Hypertrophic osteoarthrpathy (HO) is a rare paraneoplasic syndrome associated with non-small cell lung cancer (NSCLC). The pathophysiology of HO is unknown but was recently related to enhanced levels of urine prostaglandin E2 (PGE2). Here, we report the case of a patient that presented HO in association with a resectable left upper lobe NSCLC. Following surgery and adjuvant chemotherapy, HO resolved and did not recur with development of a brain metastasis 1 year later. Interestingly, tumor cyclooxygenase-2, an enzyme responsible the synthesis of PGE2, was expressed in the primary tumor but not in the resected metastasis. PMID:26777972

    We report the results of whole genome and transcriptome sequencing of tumor and adjacent normal tissue samples from 17 patients with non-small cell lung carcinoma (NSCLC). We identified 3,726 point mutations and over 90 indels in the coding sequence, with an average mutation frequency more than 10-fold higher in smokers than in never-smokers. Novel alterations in genes involved in chromatic modification and DNA repair pathways were identified along with DACH1, CFTR, RELN, ABCB5, and HGF. Deep...
