    Full Text Available Jane L Hurwitz, Paula Scullin, Lynn CampbellDepartment of Medical Oncology, Northern Ireland Cancer Centre, Belfast, UKAbstract: Despite some recent advances in the management of advanced non-small cell lung cancer (NSCLC, prognosis for these patients remains poor. Small molecule epidermal growth factor receptor (EGFR tyrosine kinase inhibitors (TKIs have however provided a new therapeutic option in this disease setting and EGFR mutation testing is now routine practice for newly diagnosed NSCLC patients. A proportion of patients will not respond to first-generation EGFR-TKIs however, and those who do will ultimately develop resistance and disease relapse. Next-generation EGFR-TKIs which inhibit multiple members of the EGFR family are being developed in order to increase sensitivity and overcome resistance to existing agents. Afatinib (BIBW 2992 is an oral, irreversible inhibitor of EGFR and HER2 tyrosine kinases and is the most advanced of these agents in clinical development. Pre-clinical and early-phase clinical trials have demonstrated a favorable safety profile as a single agent and in combination with other anti-cancer agents, and provide evidence of clinical activity in advanced NSCLC. The LUX-Lung trials suggest that for selected patients, afatinib offers symptomatic improvement and prolonged progression-free survival, although this has not yet translated into improved overall survival. This article aims to review the use of EGFR-TKIs in the management of advanced NSCLC and the mechanisms underlying resistance to these agents. We will discuss the current pre-clinical and clinical data regarding afatinib, its potential to overcome resistance to first-generation TKIs, and its emerging role in advanced NSCLC treatment.Keywords: EGFR, tyrosine kinase inhibitor, mutation, LUX-lung

    Full Text Available Globally, Lung cancer is the leading cause of cancer-related death of high morbidity and mortality with poor prognosis, which needs some more effective and less toxic therapies. The immunotherapies offer a novel approach for the treatment of patients with non-small cell lung cancer (NSCLC in both the adjuvant and palliative disease settings. A number of promising immunotherapies based on different mechanism have now been evaluated showing an increasing response rate. Moreover, further phase II/III clinical trials will be indicated to explore its value. These include checkpoint inhibitors (anti-CTLA4 antibody, anti-PD-1 antibody, anti-PD-L1 antibody, active vaccination (L-BLP25 liposome vaccine, Belagenpumatucel-L vaccine, MAGE-A3 protein vaccine and adoptive vaccination (CIK cells. The purpose of this paper will draw a summary on the theory, clinical trials, toxicity and problems to be solved of the immunotherapies in NSCLC.

    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.

    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.

    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.

    Locally advanced non-small cell lung cancer (NSCLC) continues to be a challenging disease to treat. With high rates of both local and distant failures, there is significant interest in finding more biologically active chemotherapy regimens that can contribute to reduce both failures. The phase III PROCLAIM trial, recently published in the Journal of Clinical Oncology entitled“PROCLAIM: randomized phase III trial of pemetrexed–cisplatin or etoposide–cisplatin plus thoracic radiation therapy followed by consolidation chemotherapy in locally advanced nonsquamous non-small-cell lung cancer”, compared two different chemotherapy regimens given concurrently with radiotherapy in patients with stage III non-squamous lung cancer: pemetrexed plus cisplatin versus cisplatin plus etoposide. Both groups received con-solidation chemotherapy. After enrolling 598 of planned 600 patients, the study was stopped early due to futility as no difference was seen in the primary end-point of overall survival. Since PROCLAIM was designed as a superiority trial, these results suggest that pemetrexed regimens do not offer a clinical advantage over standard cisplatin plus etopo-side. There are some subpopulations who might still benefit from pemetrexed, especially if clinicians are concerned about myelosuppression-related adverse events. Future trials are needed to investigate novel biologic agents and irradiation techniques that can result in more durable local and distant disease control in locally advanced 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

Many patients are not suitable for treatment with epidermal growth factor receptor tyrosine kinase inhibitors (eg, gefitinib, erlotinib, and afatinib or with anaplastic lymphoma kinase inhibitors (eg, crizotinib and ceritinib. As a result, anti-PD-1/PD-L1 and CTLA-4 inhibitors may play a novel role in the improvement of outcomes in a metastatic setting. The regulation of immune surveillance, immunoediting, and immunoescape mechanisms may play an interesting role in this regard either alone or in combination with current drugs. Here, we discuss advances in immunotherapy for the treatment of metastatic non-small-cell lung cancer as well as future perspectives within this framework.

    Historically, patients with advanced stage non-small cell lung cancer (NSCLC) were treated with chemotherapy alone, but a therapeutic plateau has been reached. Advances in the understanding of molecular genetics have led to the recognition of multiple molecularly distinct subsets of NSCLC. This in turn has led to the development of rationally directed molecular targeted therapy, leading to improved clinical outcomes. Tumour genotyping for EGFR mutations and ALK rearrangement has meant chemotherapy is no longer given automatically as first-line treatment but reserved for when patients do not have a 'druggable' driver oncogene. In this review, we will address the current status of clinically relevant driver mutations and emerging new molecular subsets in lung adenocarcinoma and squamous cell carcinoma, and the role of targeted therapy and mechanisms of acquired resistance to targeted therapy.

    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.

    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.

    Lung cancer is the most common cause of cancer-related mortality in men and women. Non-small cell lung cancer (NSCLC) represents close to 90% of all lung cancers. When diagnosed, >50% of patients are >65 years old. Through an improved understanding of the molecular mechanisms involved in lung oncogenesis, molecular-targeted approaches have become an essential element for the treatment of patients with NSCLC. As the toxicity profiles of the techniques are definitely more favorable compared with chemotherapy, they are particularly attractive for use in elderly patients, who are potentially more susceptible to the toxicity of systemic oncological therapies. However, studies on the activity of molecular-targeted agents in this aged patient setting are much more limited compared with those in their younger counterparts. In the present review, the literature on molecular-targeted therapy for elderly patients with advanced NSCLC is discussed. It is concluded that bevacizumab should be reserved only for highly select elderly patients with advanced NSCLC when the clinician deems it useful in the face of acceptable toxicities. In elderly patients with advanced epidermal growth factor receptor mutation-positive NSCLC, erlotinib and gefitinib appear to repeat the same favorable performance as that documented on a larger scale in the overall population of patients with activating mutations. A good toxicity profile is also confirmed for active molecules on different pathways, such as crizotinib.

    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.

    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 Beckground/Aim. Neuroendrocine lung tumors are histologically heterogenous group of cancers with different clinical progression. In non-small cell lung cancer (NSCLC neuroendocrine differentiation exists in 10-30% of patients. The aim of this study was to determine the frequency and influence of neuroendocrine differentiation on survival of treated patients with advanced non-small cell lung cancer (NSCLC. Methods. A clinical trial included 158 patients (74% males and 26% females, with the diagnosis of NSCLC, determined by histological verification. The patients were treated by combined chemo - and X-ray therapy in stage III (without pleural effusion or chemotherapy only in stage III (with pleural effusion and stage IV. Chemotherapy was conducted until progression of the disease, but no more than six cycles. When the progression had been noted in stage III (without pleural effusion, the treatment was continued with X-ray therapy. Neuron specific enolase, chromogranin A, as well as synapthophysin expression in tissue examples were determined by immunohistochemical analysis with monoclonal mouse anti-human-bodies. Survival was assessed within a year and two years follow-up examination. Results.

    Lung cancer is the common fatal illness with the highest incidence and mortality globally. Epidermal growth factor receptor overexpression by tumor cells is associated with uncontrolled proliferation, angiogenesis, anti-apoptotic signals, metastization, and invasiveness. CIMAvax-EGF vaccine consists of a chemical conjugate of the EGF with the P64 protein derived from the Meningitis B bacteria and Montanide ISA 51, as adjuvant. The vaccine is projected to induce antibodies against EGF that results in EGF withdrawal. CIMAvax-EGF demonstrated to be safe and immunogenic in advanced non-small cell lung cancer (NSCLC) patients. The efficacy study was an open-label, multicentric Phase III clinical trial, which enrolled 405 advanced NSCLC patients. Patients with proven stage IIIB/IV NSCLC, who had completed four to six cycles of chemotherapy (CTP) were randomized to receive CIMAvax-EGF or best supportive care. CIMAvax-EGF resulted in a significantly larger overall survival in patients receiving at least four doses. High EGF concentration at baseline was a good predictive biomarker of the vaccine activity and a poor prognostic biomarker for the non-treated population. The proportion of CD8+CD28− cells, CD4 cells, and the CD4/CD8 ratio after first-line CTP was also associated with CIMAvax-EGF clinical benefit. After completing the Phase III, a Phase IV trial was done where the vaccine was administered in primary care units. Administering the vaccine at primary care institutions granted better access and treatment compliance. Safety was confirmed. Several clinical trials are currently ongoing to validate EGF as a predictive biomarker of CIMAvax-EGF efficacy.

    Full Text Available Seigo Minami,1 Takashi Kijima2 1Department of Respiratory Medicine, Osaka Police Hospital, 2Department of Respiratory Medicine, Allergy and Rheumatic Diseases, Osaka University Graduate School of Medicine, Osaka, Japan Abstract: Pemetrexed, a multitargeting antifolate cytotoxic drug, plays a leading role in front-line chemotherapy for patients with advanced non-squamous non-small-cell lung cancer (NSCLC. Following its approval as second-line monotherapy for locally advanced or metastatic non-squamous NSCLC, pemetrexed has established itself as the first-line regimen in combination with cisplatin, and its powerful antitumor effects and less cumulative toxicities were then taken advantage of in the JMEN and PARAMOUNT trials, respectively, to pioneer a new treatment strategy of switch and continuation maintenance monotherapy. These developments have brought about a marked paradigm shift, and made pemetrexed indispensable in the treatment for non-squamous NSCLC. So far, only three drugs have been approved for maintenance therapy; pemetrexed both by switch and continuation maintenance, erlotinib by switch maintenance, and bevacizumab by continuation maintenance. Compared with observation alone after defined cycles of the first-line chemotherapy, subsequent pemetrexed maintenance therapy has provided significantly longer survival and infrequent severe adverse events. The cost-effectiveness of pemetrexed maintenance therapy is controversial, as well as the other two maintenance drugs, bevacizumab and erlotinib. The latest attractive attention is a combination maintenance therapy. We may have to consider epidermal growth factor receptor (EGFR mutation status for selection of a combination pattern. A combination maintenance therapy of pemetrexed plus bevacizumab is potential for patients with wild-type EGFR status, while a EGFR tyrosine kinase inhibitor-containing combination is promising for patients with active EGFR mutation status. Pemetrexed will be

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.

    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.

    Non-small-cell lung cancer (NSCLC) remains a significant global health challenge and the leading cause of cancer-related mortality. The traditional 'one-size-fits-all' treatment approach has now evolved into one that involves personalized strategies based on histological and molecular subtypes. The molecular era has revolutionized the treatment of patients harboring epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK) and ROS1 gene aberrations. In the appropriately selected population, anti-tumor agents against these molecular targets can significantly improve progression-free survival. However, the emergence of acquired resistance is inevitable. Novel potent compounds with much improved and rational selectivity profiles, such as third-generation EGFR T790M resistance mutation-specific inhibitors, have been developed and added to the NSCLC armamentarium. To date, attempts to overcome resistance bypass pathways through downstream signaling blockade has had limited success. Furthermore, the majority of patients still do not harbor known driver genetic or epigenetic alterations and/or have no new available treatment options, with chemotherapy remaining their standard of care. Several potentially actionable driver aberrations have recently been identified, with the early clinical development of multiple inhibitors against these promising targets currently in progress. The advent of immune checkpoint inhibitors has led to significant benefit for advanced NSCLC patients with durable responses observed. Further interrogation of the underlying biology of NSCLC, coupled with modern clinical trial designs, is now required to develop novel targeted therapeutics rationally matched with predictive biomarkers of response, so as to further advance NSCLC therapeutics through the next decade.

    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.

    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.

    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

    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.

    Full Text Available Sacha I Rothschild Department of Internal Medicine, Medical Oncology, University Hospital Basel, Basel, Switzerland Abstract: Rearrangements in ALK gene and EML4 gene were first described in 2007. This genomic aberration is found in about 2%–8% of non-small-cell lung cancer (NSCLC patients. Crizotinib was the first ALK tyrosine kinase inhibitor licensed for the treatment of metastatic ALK-positive NSCLC based on a randomized Phase III trial. Despite the initial treatment response of crizotinib, disease progression inevitably develops after approximately 10 months of therapy. Different resistance mechanisms have recently been described. One relevant mechanism of resistance is the development of mutations in ALK. Novel ALK tyrosine kinase inhibitors have been developed to overcome these mutations. Ceritinib is an oral second-generation ALK inhibitor showing clinical activity not only in crizotinib-resistant ALK-positive NSCLC but also in treatment-naïve ALK-positive disease. In this paper, preclinical and clinical data of ceritinib are reviewed, and its role in the clinical setting is put into perspective. Keywords: lung cancer, ALK, ceritinib, crizotinib

    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 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

    Cisplatin-based chemotherapy is being tried in the treatment of nonoperable cases of non-small-cell lung cancer (NSCLC). However, the prognosis is unfavorable and to improve survival, clinical studies using various combinations of a variety of drugs as well as experimental material are in progress. We compared the efficacy and toxicities of combination chemotherapy using different doses of vinorelbine and ifosfamide with a constant dose of cisplatin in this study. Patients diagnosed with inoperable stage III or IV NSCLC between June 1997 and December 1998 were included. Cisplatin was administered at a constant dose of 80 mg/m2 on day 5, whereas vinorelbine on days 1 and 5 and ifosfamide on day 5 were administered in one of two different doses. In arm A, vinorelbine 25 mg/m2 and ifosfamide 3.0 g/m2 were administered. In arm B, vinorelbine 20 mg/m2 and ifosfamide 2.5 g/m2 were administered. Also, we reviewed for phase II and III studies that test 1) cisplatin, 2) vinorelbine monotherapy, and 3) vinorelbine/cisplatin/ifosfamide combination chemotherapy for stage IIIb-IV non-SCLC. Summation dose intensity (SDI) was calculated in each published and current study. Twenty patients in arm A and 35 patients in arm B were available for evaluation. There was no difference in patient activity, pathologic diagnosis, and differentiation or stage between the two arms. The median number of cycles was four in both arms. The response rate was 50% in arm A and 30% in arm B. The median survival times for arm A and B were 40 and 42 weeks, respectively, whereas the SDI was 1.94 and 1.7, respectively. More than grade III leukopenia was observed in 28.9% in arm A, which is more frequent than the 17.2% in arm B. There was a significant correlation between the SDIs and response rates and median survival (r2 = 0.629, p = 0.001; r2 = 0.453, p = 0.001, respectively). Although the follow-up period is relatively short, the survival time was similar in both arms. Because a high response rate may

    Objective: To explore the clinical application value of prognostic nutritional index(PNI) for predicting overall survival(OS) in patients with advanced non-small cell lung cancer (NSCLC). Methods: 123 patients with histologically confirmed non-small cell lung cancer were enrolled in this study, and their clinical and laboratory data were reviewed. The PNI was calculated as 10×serum albumin value+ 5×total lymphocyte countin peripheral blood.Univariate and multivariate analyses were used to identify the potential prognostic factors for advanced NSCLC. Results: PNI of the 123 NSCLC patients was 46.24±6.56. PNI was significantly associated with age, weight loss and pleural effusion (P0.05). The median OS of the 123 patients was 19.5 months. The median OS in the higher PNI group (PNI≥46.24) and lower PNI group(PNI<46.24) were 25.2 months and 16.4 months, respectively.The 1-year survival rates were 80.6% and 63.9%, and 2-year survival rates were 54.8% and 19.6%, respectively (P<0.01). Univariate analysis showed that PNI, age, dyspnea, and weight loss were related to the OS of the advanced NSCLC patients (P<0.05). Multivariate analysis identified PNI as an independent prognostic factor for OS of advanced NSCLC (P<0.001). Conclusion: PNI can be easily calculated, and may be used as a relatively new prognostic indicator for advanced NSCLC in clinical practice.

    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.

    Micro-abstract In a Phase I dose-finding study of metronomic daily oral vinorelbine in advanced non-small-cell lung cancer, a recommended dose was established for this therapeutic approach. In addition, this trial revealed promising efficacy data and an acceptable tolerability profile. The observed vinorelbine blood concentrations suggest continuous anti-angiogenic coverage. Introduction We present a Phase I dose-finding study investigating metronomic daily oral vinorelbine (Navelbine® Oral, NVBo) in advanced non-small-cell lung cancer (NSCLC). Patients and methods Patients with stage III/IV NSCLC received daily NVBo at fixed dose levels of 20–50 mg/d for 21 days of each 4-week cycle. Primary end point was the maximum tolerated dose. Secondary end points included tumor response, time to progression (TTP), overall survival (OS) and tolerability. Results Twenty-seven patients with advanced NSCLC were enrolled. Most of them were extensively pretreated. Daily NVBo was well tolerated up to 30 mg/d. At 40 mg/d, two of five patients experienced dose-limiting toxicities (DLTs). Three of six patients had DLTs at the 50 mg/d level. The recommended dose was established at 30 mg/d in cycle 1, with escalation to 40 mg/d in cycle 2, if tolerated. Pharmacokinetic analyses showed continuous blood exposure over 21 days and only marginal accumulation. The tolerability profile was acceptable (all dose levels – all grades: decreased appetite 33%, diarrhea 33%, leukopenia 33%, nausea 30%, vomiting 26%; ≥grade 3: leukopenia 30%, lymphopenia 19%, neutropenia 19%, febrile neutropenia 15%). Disease control rate, OS and TTP signaled a treatment effect. Conclusion Daily metronomic NVBo therapy in extensively pretreated patients with advanced NSCLC is feasible and safe at the recommended dose of 30 mg/d. Escalation to 40 mg/d in the second cycle is possible. The blood concentrations of vinorelbine after daily metronomic dosing reached lower peaks than intravenous or oral conventional

    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.

  10. Efficacy and safety of gefitinib as monotherapy for Chinese patients with advanced non-small cell lung cancer

    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.

    2014-09-01

    The availability of antineoplastic monoclonal antibodies, small molecules and newer cytotoxics such as pemetrexed, the EGFR-tyrosine kinase inhibitors erlotinib, gefitinib, afatinib as well as the anti-angiogenic bevacizumab and the ALK-inhibitor crizotinib has recently changes the treatment algorithm of advanced non-small cell lung cancer. Decision making in 2014 is characterized by customizing therapy, by selecting a specific therapeutic regimen based on the histotype and the genotype of the tumour. This refers to first-line induction therapy and maintenance therapy as well, but also to subsequent lines of therapy since anti-neoplastic drugs and regimens used upfront clinically influence the selection of agents/regimes considered for second-/third-line treatment. Consequently, therapy customization through tumour histology and molecular markers has significantly influenced the work of pathologists around the globe and the process of obtaining an extended therapeutically relevant tumour diagnosis. Not only histological sub-typing became standard but molecular information is also considered of increasing importance for treatment selection. Routine molecular testing in certified laboratories must be established, and the diagnostic process should ideally be performed under the guidance of evidence based recommendation. The process of investigating and implementing medical targeting in lung cancer therefore, requires advanced diagnostic techniques and expertise and because of its large dimension is costly and influenced by the limitation of financial and clinical resources.

    Full Text Available Sacha I Rothschild Department of Internal Medicine, Medical Oncology, University Hospital Basel, Basel, Switzerland Abstract: The therapeutic landscape in non-small-cell lung cancer (NSCLC is changing. The description of molecular alterations leading to NSCLC carcinogenesis and progression (so-called oncogenic driver mutations and the development of targeted agents interfering with the tumor-promoting intracellular signaling pathways have improved the outcome for many patients with advanced/metastatic NSCLC. However, many patients with stage IV NSCLC do not have one of the targetable predictive biomarkers, and are therefore in need of classical chemotherapy. This especially applies to squamous cell cancer. A platinum-based doublet chemotherapy is the standard of care for patients with stage IV NSCLC. As second-line therapies, docetaxel, pemetrexed, and the EGFR tyrosine-kinase inhibitor erlotinib have demonstrated benefit in Phase III randomized trials. Recently, the addition of the angiokinase inhibitor nintedanib to docetaxel has proven efficacious, and is a new treatment option in the second-line setting. Preclinical and clinical data of nintedanib for the treatment of lung cancer patients are reviewed here. Keywords: nintedanib, lung cancer, angiokinase inhibitor, VEGFR, PDGF, FGFR

    The role of non-platinum combination chemotherapy in the treatment of advanced non-small-cell lung cancer (NSCLC) has not yet been clarified. In this phase I study, the dose-limiting toxicity (DLT), the maximum tolerable dose (MTD) and the antitumor activity of a two-drug combination of docetaxel (DCT) and irinotecan (CPT) in patients with advanced NSCLC were evaluated. Previously untreated patients with NSCLC in stage IIIB with malignant pleural effusion or stage IV were eligible. Both drugs were administered by 1-h intravenous infusion on day 1, and repeated every 3 weeks. DCT was given before CPT administration. Five escalating dose levels of DCT/CPT (40/135, 50/135, 50/150, 60/150, and 60/165 mg/m2) were studied. Eighteen patients received 44 courses. The DLT was considered to be neutropenia, because grade 4 neutropenia lasting for 3 days or more was observed in three patients, which was accompanied with three episodes of febrile neutropenia. As a non-hematological toxicity, grade 3 diarrhea occurred in three patients. Since all the three patients treated at the fifth dose level (DCT at 60 mg/m2 and CPT at 165 mg/m2) experienced DLT (grade 4 neutropenia in two patients and grade 3 hepatic toxicity in one), this dose level was determined to be the MTD. The objective response rate was 33.3%, and the median survival time was 13.6 months. To confirm the effectiveness of this combination for advanced NSCLC which was suggested in the present study, a phase II study with the recommended doses (150 mg/m2 for CPT and 50-60 mg/m2 for DCT) is warranted.

    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.

    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.

    Full Text Available Background and objective Gemcitabine-platinum-combined with chemotherapy is the most common treatment for advanced non-small cell lung cancer (NSCLC. Gemcitabine is administered once a week in a general three-week schedule. In the present study, gemcitabine is administered on d1 and d5 to improve compliance, and the efficacy and safety of the improved regimen is evaluated in untreated patients with advanced NSCLC. Methods A total of 83 patients were enrolled between October 2007 and October 2009. In each cycle, gemcitabine was administered at a dose of 1,000 mg/m2-1,250 mg/m2 via a 30 min intravenous infusion on d1 and d5 followed by cisplatin at a dose of 75 mg/m2 or carboplatin (AUC=5 on d1 every three weeks. At least two cycles of chemotherapy were completed in each case, and clinical response and toxicity of the regimen were observed. Results The objective response rate was 37.3%. The median progression free survival and overall survival time were 6.1 months and 15.0 months, respectively. The one-year and two-year survival rates were 57.8% and 16.2%, respectively. Myelosuppression and gastrointestinal responses were the main toxicities. The incidence of grade 3/4 of leucopenia, hypohemia, and thrombocytopenia were 26.5%, 10.8% and 7.2%, respectively. A total of 27.5% of the patients in the cisplatin group had grade 3/4 gastrointestinal responses. Treatment related deaths were not observed in this study. Conclusion The regimen is active and well-tolerated in untreated patients with advanced NSCLC. Further randomized controlled studies are necessary.

    Objective To investigate the clinical effect and the overall survival (OS) rate of patients with advanced non-small cell lung cancer (NSCLC) who have undergone Wheel Balance Cancer Therapy (WBCT). Methods The cases of 33 patients with advanced NSCLC who were treated with WBCT at the East West Cancer Center (EWCC) between October 4, 2004, and October 3, 2013, without undergoing concurrent conventional treatment were analyzed. The Kaplan-Meier method was used to estimate the OS of the cases, and the median OS was calculated according to age, Eastern Cooperative Oncology Group Performance Status (ECOG PS), conventional-treatment history, WBCT treatment duration, and histological tumor type. Results The median OS of all patients was 31.1 (95% confidence interval [CI] = 3.5-58.7) months; the OS rates were 63.6% and 24.2% at years 1 and 2, respectively. The median OS rates of patients under and over 65 years were 45.2 (95% CI = 13.5-76.9) and 19.5 (95% CI = 7.1-31.8) months, respectively (P = .189). The median OS rates of patients who received WBCT for >14 days but treatment and those who had not were 45.2 (95% CI = 9.1-81.3) and 3.9 (95% CI = unable to calculate) months, respectively (P = .000). The median OS rates of patients with squamous cell carcinoma (SCC) and non-SCC lung cancer were 5.6 (95% CI = unable to calculate) and 45.2 (95% CI = 9.1-81.3) months, respectively (P = .262). The median OS rate of patients with ECOG PS ≥3 was 14.3 (95% CI = 8.8-19.8) months; that of patients ECOG PS treatment and have an ECOG PS <3.

    The assessment of special categories of non-small-cell lung cancer (NSCLC) patients requires a comprehensive analysis of all factors potentially influencing the daily quality of life and the relative contribution of tumor-related symptoms on the overall patient health status. While for elderly patients prospective evidence and recommendations allow clinicians to better address their patients to a shared treatment, a paucity of reliable data refers to treatment opportunities for these patients, termed frail or unfit, who are not considered eligible for chemotherapy usually administered to adult patients. This consensus was inspired by the absence of clear criteria to define the category of unfit patients in the context of advanced NSCLC in order to share all the available tools for their classification and evaluation and to support decisions for clinical practice on a daily basis. After review of the literature and panelist consensus, a series of items was identified as relevant: age, performance status, renal function, heart failure, previous cerebrovascular events, uncontrolled hypertension, neuropathy, hearing loss, symptomatic brain metastases, severe psychiatric disorders, and absence of caregiver support. On the basis of these factors, a treatment algorithm for clinical practice to categorize unfit NSCLC patient into 3 major clinical scenarios was defined: (1) unfit for cisplatin-based chemotherapy, (2) unfit for carboplatin-based chemotherapy, and (3) unfit for single-agent chemotherapy.

    Full Text Available Objective: The aim of this study was to evaluate elevated platelet count as a prognostic factor for survival in patients with advanced (stage IIIB/ IV non- small cell lung cancer (NSCLC receiving first- line chemotherapy. Methods: From 2005 to 2009 three hundreds forty seven consecutive patients with stage IIIB or IV NSCLC, treated in Department of Medical Oncology, UMHAT "Dr Georgi Stranski" entered the study. The therapeutic regimens included intravenous administration of platinum- based doublets. Survival analysis was evaluated by Kaplan- Meier test. The influence of pretreatment thrombocytosis as prognostic factor for survival was analyzed using multivariate stepwise Cox regression analyses. Results: Elevated platelet counts were found in 78 patients. The overall survival for patients without elevated platelet counts was 9,6 months versus 6,9 months for these with thrombocytosis. In multivariate analysis as independent poor prognostic factors were identified: stage, performance status and elevated platelet counts. Conclusions: These results indicated that platelet counts as well as some clinical pathologic characteristics could be useful prognostic factors in patients with unresectable NSCLC.

    To determine the efficacy and tolerability of SPI-77 (sterically stabilised liposomal cisplatin) at three dose levels in patients with advanced non-small-cell lung cancer (NSCLC). Patients had Stage IIIB or IV NSCLC and were chemo-naïve, and Eastern Oncology Cooperative Group 0-2. The first cohort received SPI-77 at 100 mg m-2, the second 200 mg m-2 and the final cohort 260 mg m-2. Patients had also pharmacokinetics and analysis of leucocyte platinum (Pt)-DNA adducts performed. Twenty-six patients were treated, with 22 patients being evaluable for response. Only one response occurred at the 200 mg m-2 dose level for an overall response rate of 4.5% (7.1% at >or=200 mg m-2). No significant toxicity was noted including nephrotoxicity or ototoxicity aside from two patients with Grade 3 nausea. No routine antiemetics or hydration was used. The pharmacokinetic profile of SPI-77 was typical for a liposomally formulated drug, and the AUC appeared to be proportional to the dose of SPI-77. Plasma Pt levels and leucocyte DNA adduct levels did not appear to rise with successive doses. SPI-77 demonstrates only modest activity in patients with NSCLC.

    2014-02-01

    Afatinib (Gilotrif™, Giotrif(®)) is an orally administered, irreversible inhibitor of the ErbB family of tyrosine kinases. Afatinib downregulates ErbB signalling by covalently binding to the kinase domains of epidermal growth factor receptor (EGFR), human epidermal growth factor receptor (HER) 2 and HER4, resulting in irreversible inhibition of tyrosine kinase autophosphorylation; it also inhibits transphosphorylation of HER3. Afatinib is approved as monotherapy for the treatment of EGFR tyrosine kinase inhibitor (TKI)-naïve adults with locally advanced or metastatic non-small cell lung cancer (NSCLC) with activating EGFR mutations in the EU, and for the first-line treatment of patients with metastatic NSCLC whose tumours have EGFR exon 19 deletions or exon 21 (L858R) substitution mutations as detected by a US FDA-approved test in the US. In two randomized, open-label, multinational phase III trials, progression-free survival was significantly prolonged with afatinib compared with pemetrexed plus cisplatin (LUX-Lung 3) or gemcitabine plus cisplatin (LUX-Lung 6) in treatment-naïve patients with advanced NSCLC with activating EGFR mutations. The objective response rate was significantly higher with afatinib than with pemetrexed plus cisplatin or gemcitabine plus cisplatin, and patient-reported outcomes for symptoms such as cough and dyspnoea and certain health-related quality of life measures significantly favoured afatinib versus pemetrexed plus cisplatin or gemcitabine plus cisplatin. Afatinib also showed efficacy in EGFR TKI-naïve patients with advanced lung adenocarcinoma and activating EGFR mutations who had received no more than one prior chemotherapy regimen for advanced disease, according to the results of the noncomparative, multinational, phase II LUX-Lung 2 trial. Oral afatinib had a manageable tolerability profile. EGFR-mediated adverse events (e.g. diarrhoea, rash/acne) were generally managed using dose reduction and delays. In conclusion, afatinib

    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.

    To evaluate the predictive value of the early response of 18F-flurodeoxyglucose positron emission tomography (FDG PET) during concurrent chemoradiotherapy (CCRT) for locally advanced non-small cell lung cancer (NSCLC). FDG PET was performed before and during CCRT for 13 NSCLC patients. Maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were measured and the changes were calculated. These early metabolic changes were compared with the standard tumor response by computed tomograms (CT) one month after CCRT.One month after the completion of CCRT, 9 patients had partial response (PR) of tumor and 4 patients had stable disease. The percent changes of SUVmax (%DeltaSUVmax) were larger in responder group than in non-responder group (55.7% +/- 15.6% vs. 23.1% +/- 19.0%, p = 0.01). The percent changes of SUVmean (%DeltaSUVmean) were also larger in responder group than in non-responder group (54.4% +/- 15.9% vs. 22.3% +/- 23.0%, p = 0.01). The percent changes of MTV (%DeltaMTV) or TLG (%DeltaTLG) had no correlation with the tumor response after treatment. All the 7 patients (100%) with %DeltaSUVmax > or = 50% had PR, but only 2 out of 6 patients (33%) with %DeltaSUVmax < 50% had PR after CCRT (p = 0.009). Likewise, all the 6 patients (100%) with %DeltaSUVmean > or = 50% had PR, but only 3 out of 7 patients (43%) with %DeltaSUVmean < 50% had PR after CCRT (p = 0.026). The degree of metabolic changes measured by PET-CT during CCRT was predictive for NSCLC tumor response after CCRT.

    In order to evaluate the clinical efficacy and the safety profile of molecularly targeted therapies as a palliative approach in elderly populations affected by advanced thoracic neoplasms, we retrospectively studied, in terms of effectiveness and toxicities, a group of pretreated elderly metastatic non-small cell lung cancer (NSCLC) patients admitted to our institution and treated with erlotinib at standard daily/dose. Forty-three patients aged 70 years or older who had previously failed on chemotherapy or radiotherapy were treated with oral Eerlotinib (150 mg/d) until disease progression or unacceptable toxicity. Clinical data, pathological types, potential prognostic factors, efficacy and toxicity of erlotinib were included in this analysis. In our series we observed: objective responses in six patients (14%) and stable disease in 15 (35%). Skin rash was the most common side effect (67%). Grade 3-4 adverse events were observed in 16 cases (37%). The median overall survival and the median progression-free survival were 8.4 months (CI 95%: 0.7-43.6) and 3 months (CI 95%: 0.4-28.4), respectively. Patients with adenocarcinoma achieved the best disease control rate (p = 0.027), while not/former smokers showed a better response (p = 0.069). In our experience the use of erlotinib after chemotherapy failure in an unselected elderly population affected by NSCLC showed moderate efficacy and a moderate safety profile. However, erlotinib represents a valid option in this setting, but other factors such as biological information, comorbidities and concomitant medications need to be carefully take into consideration in this particular subset of cancer patients.

    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.

    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.

    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.

    The activation of lymphocytes by gefitinib treatment has been described. In this phase II pilot trial, we explored the possible synergism between IL-2 and gefitinib for non-small cell lung cancer (NSCLC) treatment. From September, 2003, to November, 2006, 70 consecutive patients with advanced, progressive NSCLC, previously treated with chemotherapy, received oral gefitinib 250 mg daily. The first 39 patients received gefitinib alone (G group). The other 31 also received subcutaneous IL-2 (GIL-2 group): 1 MIU/m{sup 2} (Million International Unit/m{sup 2})twice a day on Days 1 and 2, once a day on Days 3, 4, 5 every week for four consecutive weeks with a four-week rest period. Median follow-up was 25.2 months. Grade 3–4 toxicity of gefitinib was represented by skin rash (7%), asthenia/anorexia (6%) and diarrhea (7%); patients treated with IL-2 showed grade 2–3 fever (46%), fatigue (21%) and arthralgia (13%). 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

    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

    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.

The purpose of this article was to review the economics of first-line and maintenance NSCLC treatments. We reviewed economic analyses of NSCLC therapies published between 2004 and 2014. In first-line settings, in unselected patients with advanced NSCLC, the cisplatin gemcitabine doublet appears to be cost-saving compared with other platinum doublets. In patients with nonsquamous NSCLC, the incremental cost-effectiveness ratios (ICERs per life-year gained (LYG were $83,537, $178,613, and more than $300,000 for cisplatin-pemetrexed compared with, respectively, cisplatin-gemcitabine, cisplatin-carboplatin-paclitaxel, and carboplatin-paclitaxel-bevacizumab. For all primary chemotherapy agents, use of carboplatin is associated with slightly higher costs than cisplatin. In all the analysis, bevacizumab had an ICER greater than $150,000 per quality-adjusted life-year (QALY. In epidermal growth factor receptor mutated advanced NSCLC, compared with carboplatin-paclitaxel doublet, targeted therapy based on testing available tissue yielded an ICER of $110,644 per QALY, and the rebiopsy strategy yielded an ICER of $122,219 per QALY. Compared with the triplet carboplatin-paclitaxel-bevacizumab, testing and rebiopsy strategies had ICERs of $25,547 and $44,036 per QALY

    A 59-year-old woman with epidermal growth factor receptor gene (EGFR) mutation-positive advanced lung adenocarcinoma was treated with afatinib after a diagnosis of chronic myelomonocytic leukemia (CMML). Twenty-one weeks later, she developed agranulocytosis, and CMML subsequently progressed to blast crisis. After complete remission of CMML, gefitinib was initiated; however, agranulocytosis recurred. This is the first reported case of both EGFR mutation-positive advanced non-small cell lung cancer with CMML, and of CMML blast crisis. Physicians should be aware of such risks and monitor EGFR-TKI-treated patients with myeloid neoplasms accordingly.

    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.

    Thrombospondin-2 (TSP-2) is an endogenous negative regulator of vascularization in human cancer. TSP-2 regulates angiogenesis through binding and sequestration of the proangiogenic fibroblast growth factor-2 (FGF-2). However, it is unclear whether TSP-2 and FGF-2 are related to prognosis in non-small cell lung cancer (NSCLC). To study this issue, we measured serum (Elisa) levels of TSP-2 and FGF-2 in 40 NSCLC patients (before chemotherapy) and 22 healthy subjects. Both TSP-2 and FGF-2 concentrations were elevated in the NSCLC group compared with control (TSP-2: 26.72±8.00 vs. 18.64±5.50 ng/ml, p=0.002; FGF-2: 11.90±5.80 vs. 7.26±3.90 pg/ml, p=0.01). Receiver-operating characteristic (ROC) curves were applied to find the cut-off serum levels of TSP-2 and FGF-2 (NSCLC vs. healthy: TSP-2=15.09 ng/ml, FGF-2=2.23 pg/ml). Patients before treatment with the TSP-2 level24.15 ng/ml had only 9 months' median survival (p=0.007). Patients with FGF-2 level>11.21 pg/ml had significantly shorter survival than patients with FGF-2FGF-2 than healthy people. High levels of TSP-2 and FGF-2 may predict worse survival.

    Full Text Available With the advances of technology, great progresses have been made in liquid biopsy in recent years. Liquid biopsy is currently playing a more and more important role in early diagnosis and treatment of cancer. Compared with traditional tissue biopsy, liquid biopsy is more popular in clinical practice due to its non-invasiveness, convenience and high repeatability. It has huge potential in the future. This review introduces circulating tumor cells (CTCs and circulating tumor DNA (ctDNA as the most important objects in liquid biopsy, mainly focusing on their history, biological characteristics, detection technologies, limitations and applications in non-small cell lung cancer.

    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

    Cisplatin-based chemotherapy improves survival in appropriately selected patients with stage IV non-small cell lung cancer (NSCLC). However, cisplatin-based regimens have well-known dose-related toxicities, particularly renal insufficiency and neurotoxicity. On the basis of prior preclinical and phase I studies, we initiated a phase II study of SPI-77 (STEALTH) Liposomal Cisplatin) in patients with stage IIIB and IV NSCLC who failed previous treatment with platinum. Disease in all subjects had progressed during therapy, failed to respond, or progressed within 3 months after discontinuing the platinum-based chemotherapy. Between January and June 1999, 13 patients were enrolled at our institution. Patient characteristics included: seven women, six men; median age, 61 years; median Karnofsky performance status, 80%; median number of prior chemotherapy regimens, two (range, 1-3). All patients had adequate hepatic and renal function. SPI-77 was administered at a dose of 260 mg/m(2) IV every 3 weeks. A median of two cycles (range 1-6) were given; the total number of cycles was 35. Among the 12 patients evaluable for response, two had (17%) stable disease and ten (83%) had progressive disease. The median survival was 24.3 weeks, and the median follow-up was 43.9 weeks. Toxicity could be evaluated in all subjects. Moderate anemia (46% of cycles, or=grade 3) with minimal granulocytopenia and thrombocytopenia (26% of cycles grade 1; 0% of cycles, >or=grade 2) were the most notable manifestations of myelosuppression. Grade 3 nonhematological toxicities included dyspnea (8%), fatigue (8%), and pain (8%). There were no grade 4 toxicities. These data suggest that this liposomal cisplatin formulation does not have appreciable activity in this population of patients with NSCLC who had received prior platinum-based chemotherapy. The lack of encouraging results from SPI-77 use in other phase I and II studies resulted in early closure of this trial by the manufacturer.

    BACKGROUND: The insulin-like growth factor 1 receptor (IGF1R) has yet to be established as a biomarker in non-small cell lung cancer (NSCLC) but could prove useful in customized chemotherapy. We explored its prognostic value using both quantitative real-time reverse transcriptase polymerase chain.......039 and 10.9 vs. 14.3 months, p=0.038, respectively). IGF1R protein expression showed a similar, although non-significant tendency. CONCLUSION: IGF1R mRNA expression may be a prognostic biomarker in advanced NSCLC and should be investigated in a larger population....

    The successes achieved by chimeric antigen receptor-modified T (CAR-T) cells in hematological malignancies raised the possibility of their use in non-small lung cancer (NSCLC). In this phase I clinical study (NCT01869166), patients with epidermal growth factor receptor (EGFR)-positive (>50% expression), relapsed/refractory NSCLC received escalating doses of EGFR-targeted CAR-T cell infusions. The EGFR-targeted CAR-T cells were generated from peripheral blood after a 10 to 13-day in vitro expansion. Serum cytokines in peripheral blood and copy numbers of CAR-EGFR transgene in peripheral blood and in tissue biopsy were monitored periodically. Clinical responses were evaluated with RECIST1.1 and immune- related response criteria, and adverse events were graded with CTCAE 4.0. The EGFR-targeted CAR-T cell infusions were well-tolerated without severe toxicity. Of 11 evaluable patients, two patients obtained partial response and five had stable disease for two to eight months. The median dose of transfused CAR(+) T cells was 0.97×10(7) cells kg(-1) (interquartile range (IQR), 0.45 to 1.09×10(7) cells kg(-1)). Pathological eradication of EGFR positive tumor cells after EGFR-targeted CAR-T cell treatment can be observed in tumor biopsies, along with the CAR-EGFR gene detected in tumor-infiltrating T cells in all four biopsied patients. The EGFR-targeted CAR-T cell therapy is safe and feasible for EGFR-positive advanced relapsed/refractory NSCLC.

    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.

    Genomic analysis of circulating tumor DNA (ctDNA) released from cancer cells into the bloodstream has been proposed as a useful method to capture dynamic changes during the course of the disease. In particular, the ability to monitor epidermal growth factor receptor (EGFR) mutation status in cell-free circulating DNA (cfDNA) isolated from advanced non-small cell lung cancer (NSCLC) patients EGFR can help to the correct management of the disease and overcome the challenges associated with tumor heterogeneity and insufficient biopsied material to perform key molecular diagnosis. Here, we report a case of long term monitorization of EGFR mutation status in cfDNA from peripheral blood in an NSCLC patient in, with excellent correlation with clinical evolution. PMID:27826535

    Clinical trials exploring the long-term effects of first-line therapy in patients with advanced non-small-cell lung cancer generally disregard subsequent treatment although most patients receive second and third-line therapies. The choice of further therapy depends on critical intermediate events such as disease progression and it is usually left at the physician's discretion. Time-dependent confounding may then arise with standard survival analyses producing biased effect estimates, even in randomized trials. Herein we describe the concept of time-dependent confounding in detail and discuss whether the response to first-line treatment may be a potential time-dependent confounding factor for survival in the context of subsequent therapy. A prospective observational study of 406 patients with advanced non-small-cell lung cancer served as an example base. There is evidence that time-dependent confounding may occur in multivariate survival analysis after first-line therapy when disregarding subsequent treatment. In the light of this important but underestimated aspect some of the large and meaningful recent clinical first-line lung cancer studies are discussed, focussing on subsequent treatment and its potential impact on the survival of the study patients. No recently performed lung cancer trial applied adequate statistical analyses despite the frequent use of subsequent therapies. In conclusion, effect estimates from standard survival analysis may be biased even in randomized controlled trials because of time-dependent confounding. To adequately assess treatment effects on long-term outcomes appropriate statistical analyses need to take subsequent treatment into account.

    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 Background and objective The epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs have been widely used in the treatment of the advanced non-small cell lung cancer (NSCLC, especially in the adenocarcinoma patients with activating EGFR mutations. But there is no published overview of the following treatment. This report through observing the efficacy, toxicity and overall survival of different treatments to the advanced NSCLC patients who had gradual progression after EGFR-TKIs, evaluates the influence of the continued treatment and switching chemotherapy. Methods Retrospective review is conducted on 32 cases of advanced NSCLC patients who experienced treatment failure of EGFR-TKIs. One group accepted the continued treatment and the other group accepted the switching chemotherapy. Results The median overall survival of the continued treatment group is 36.0 months. The respose rate of the switching chemotherapy group is 43.75%, and clinical benefit rate (complete and partial response and stable disease is 87.5%. The median overall survival is 15.5 months. The main toxicities are nausea, vomiting and hematological toxicities. Conclusion For the advanced NSCLC patients who had gradual progression after EGFR-TKIs, the continued treatment is one of the acceptable choices.

    Although many biomarkers have emerged in non-small cell lung cancer (NSCLC), the predictive value of site-specific spread is not fully defined. We designed this study to determine if there is an association between serum biomarkers and brain metastasis in advanced NSCLC. We evaluated 227 eligible advanced NSCLC patients between May 2005 and March 2010. Patients who had been newly diagnosed with stage IV NSCLC but had not received treatment previously, and had available information on at least one of the following pretreatment serum biomarkers were enrolled: carcinoembryonic antigen (CEA), cytokeratin 19 fragments (CYFRA 21-1), cancer antigen 125 (CA 125), cancer antigen 19-9, and squamous cancer cell antigen. Whole body imaging studies and magnetic resonance imaging of the brain were reviewed, and the total number of metastatic regions was scored. Brain metastasis was detected in 66 (29.1%) patients. Although serum CEA, CYFRA 21-1, and CA 125 levels were significantly different between low total metastatic score group (score 1-3) and high total metastatic score group (score 4-7), only CEA level was significantly different between patients with brain metastasis and those without brain metastasis (p present study demonstrated that the pretreatment serum CEA level was significantly correlated with brain metastasis in advanced NSCLC. These findings suggested the possible role of CEA in the pathogenesis of brain invasion. More vigilant surveillance would be warranted in the high-risk group of patients with high serum CEA level and multiple synchronous metastasis.

    Nicotinic acetylcholine receptors (nAChRs) play a key role in carcinogenesis and progression of lung cancer; and polymorphisms in CHRNA5-A3 and CHRNB3-A6, two gene clusters encoding nAChR subunits, have been associated with lung cancer risk. In this study, we investigated whether variants in the two gene clusters were associated with prognosis of advanced non-small cell lung cancer (NSCLC). A total of 165 stage IIIB-IV NSCLC patients were enrolled in this study. Three polymorphisms (rs667282 and rs3743073 in CHRNA5-A3 and rs13280604 in CHRNB3-A6) were genotyped using the TaqMan method. Overall survival (OS) was estimated using the log-rank test and the Cox models. Our results showed that patients with CHRNA5-A3 rs667282 TT or TC genotypes had a significantly shorter OS than those carrying the CC genotype (Log-rank, P = 0.043). Furthermore, multivariate Cox regression analysis showed that rs667282 TT/TC genotypes are significantly associated with increased risk of overall deaths (adjusted hazard ratio, 1.7; 95% CI, 1.1-2.7). However, the similar results were not observed for other two polymorphisms. Furthermore, no evident association was found between these variants and clinicopathologic features of advanced NSCLC. Our present study suggested that rs667282 in CHRNA5-A3 may modify the prognosis of patients with advanced NSCLC.

    Full Text Available Background and objective Pemetrexed in combination with platinum or a single-agent has been approved for the first- and second-line treatment of non-small cell lung cancer (NSCLC. However, the role of pemetrexed therapy in the third-line and beyond treatment of NSCLC has yet to be generally accepted. The present retrospective study reports the efficacy and safety of pemetrexed in the third-line and beyond treatment of advanced non-squamous NSCLC. Methods A total of 46 patients with advanced non-squamous NSCLC received a combination of pemetrexed plus platinum or a single-agent after multi-line treatment failed to yield positive results. Results Of the 46 patients who participated in the study, 7 achieved partial responses, 20 reached a stage of stable disease, and 19 reached a stage of progressive disease. The over-all object response rate was 15.2% and the disease control rate (DCR was 58.7%. The median progression-free survival time was 3.0 months. Pemetrexed in combination with platinum yielded a higher DCR than the pemetrexed plus single-agent treatment (P=0.043. Common adverse events included nausea, vomiting and myelosuppression. Conclusion Administration of pemetrexed after failure of multi-line treatment is clinically beneficial to patients with advanced non-squamous NSCLC. The toxic effects of the treatment appear to be tolerable.

    Full Text Available Background and objective The current study reported the result of bevacizumab treatment administered to 25 Chinese patients with advanced non-small cell lung cancer (NSCLC who were treated at the Peking Union Medical College Hospital as a part of the SAiL (MO19390 trial. This trial is an open, international multicenter, single-arm clinical study that assesses the safety and efficacy of first-line bevacizumab-based therapy in advanced NSCLC. Methods Twenty-five Chinese patients with advanced non-squamous NSCLC received bevacizumab (15 mg/kg combined with chemotherapy (carboplatin plus paclitaxel treatment from August 2007 to February 2008. Adverse effects (AEs, objective response rate (ORR, median time to progression (TTP, and overall survival (OS were measured. Results AEs were generally mild and reversible. The most frequent AEs were alopecia, peripheral neuropathy, rash, proteinuria, nausea/vomitting, fatigue, myalgia, bleeding, and hypertension. The partial remission and stable disease rates were 68% and 28%, respectively. The median TTP and OS of all patients were 11.2 and 19.3 months, respectively. Conclusion Bevacizumab combined with carboplatin-based chemotherapy may be well tolerated and beneficial for Chinese patients with non-squamous NSCLC.

    OBJECTIVES: The central immune co-inhibitory programmed cell death receptor/ligand 1 (PD-1/PD-L1) pathway plays a key role in tumor immune evasion in non-small cell lung cancer (NSCLC). Soluble PD-1 (sPD-1) can be detected in the blood, and preclinical evidence suggests that sPD-1 blocks PD-1/-L1...... interaction and improves anti-tumor immunity. The present study compares the concentration of sPD-1 in the serum of advanced NSCLC patients with Epidermal Growth Factor Receptor (EGFR) mutation prior to erlotinib treatment and at the time of progression and correlates these results to patient outcome....... MATERIALS AND METHODS: Blood samples from 38 patients with EGFR-mutated advanced NSCLC treated with erlotinib were analyzed for sPD-1 by sandwich ELISA. EGFR mutational status was assessed in circulating tumor DNA (ctDNA) and tumor biopsies. RESULTS: sPD-1 could be detected in 21% of patients prior...

    Full Text Available Abstract Background The main objective of this study was to evaluate the safety of second-line pemetrexed in Stage IIIB or IV NSCLC. Methods Overall, 95 patients received pemetrexed 500 mg/m2 i.v. over Day 1 of a 21-day cycle. Patients also received oral dexamethasone, oral folic acid and i.m. vitamin B12 supplementation to reduce toxicity. NCI CTC 2.0 was used to rate toxicity. All the adverse events were graded in terms of severity and relation to study treatment. Dose was reduced in case of toxicity and treatment was delayed for up to 42 days from Day 1 of any cycle to allow recovering from study drug-related toxicities. Tumor response was measured using the RECIST criteria. Results Patients received a median number of 4 cycles and 97.8% of the planned dose. Overall, 75 patients (78.9% of treated reported at least one adverse event: 34 (35.8% had grade 3 as worst grade and only 5 (5.2% had grade 4. Drug-related events occurred in 57.9% of patients. Neutropenia (8.4% and leukopenia (6.3 % were the most common grade 3/4 hematological toxicities. Grade 3 anemia and thrombocytopenia were reported in 3.2% and 2.1% of patients, respectively. Diarrhea (6.3%, fatigue (3.2% and dyspnea (3.2% were the most common grade 3/4 non-hematological toxicities. The most common drug-related toxicities (any grade were pyrexia (11.6%, vomiting, nausea, diarrhea and asthenia (9.5% and fatigue (8.4%. Tumor Response Rate (CR/PR in treated patients was 9.2%. The survival at 4.5 months (median follow-up was 79% and the median PFS was 3.1 months. Twenty patients (21.1% died mainly because of disease progression. Conclusion Patients with locally advanced or metastatic NSCLC could benefit from second-line pemetrexed, with a low incidence of hematological and non-hematological toxicities.

    Over the past 20 years, combined treatment with radiotherapy and second-generation chemotherapy drugs was extensively studied in patients with locally advanced NSCLC and became the standard over radiotherapy alone in patients with good performance status. Radiosensitizing properties of cisplatin have been identified in the laboratory. Close temporal administration of cisplatin and radiation is mandatory for enhanced antitumor efficacy, but results in significant toxicity to normal tissues. Early clinical studies demonstrated that the concurrent administration of cisplatin during STD-RT was feasible, with acceptable esophageal toxicity, and had the potential of significantly improving locoregional control. Carboplatin administered concurrently with accelerated HFX-RT was responsible for a higher rate of esophageal toxicity. Further improvement in survival also requires an effective treatment of micro-metastatic disease through full-dose delivery of cytotoxic drugs and the addition of at least one more active drug in conjunction with cisplatin and radiotherapy to further improve locoregional control of the disease. In most clinical studies, etoposide was the second drug of choice because of its own radiosensitizing properties and possible synergy with cisplatin. In numerous phase II studies, concurrent radiotherapy and PE resulted in reproducible results in terms of local control (30%-40%), median survival (15-18 months), survival at 2 years (35%-40%), and survival at 5 years (25%-30%). In phase III studies, these results were shown to be superior to radiotherapy alone and to induction chemotherapy followed by STD-RT. The question of the potential benefit of HFX-RT combined with PE has been addressed in phase II and III studies. At this time, there is no firm evidence that concurrent chemotherapy with HFX-RT is superior to concurrent chemotherapy with STD-RT in terms of local control and survival. Only a significant benefit in terms of local control or survival would

    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.

    Full Text Available Background. Huachansu, the sterilized water extract of Bufo bufo gargarizans toad skin, is used in China to alleviate the side-effects and enhance the therapeutic effect of chemotherapy in advanced non-small-cell lung cancer (NSCLC. We conducted a meta-analysis to assess Huachansu’s efficacy. Methods. We extensively searched electronic databases (CENTRAL, EMBASE, MEDLINE, CBM, Cochrane Library, CNKI, CEBM, WFDP, CSCD, CSTD, and IPA for randomized controlled trials containing Huachansu plus chemotherapy as the test group and chemotherapy as the control group. Seventeen trials were selected based on the selection criteria. The pooled relative ratio (RR of indicators with 95% confidence interval (95% CI was calculated for efficacy evaluation. Results. The meta-analysis demonstrated a statistically significant improvement in objective tumor response, one-year survival, Karnofsky performance status, pain relief, and alleviation of severe side-effects (nausea and vomiting, leukocytopenia in the test group as compared to the control group, but no significant difference in thrombocytopenia. Conclusions. This study demonstrated the efficacy of Huachansu combined with chemotherapy in the treatment of advanced NSCLC. However, limitations exist and high-quality trials are needed for further verification.

    A combination of S-1, a newly developed oral 5-fluorouracil derivative, and cisplatin is reported to show anti-tumour activity against advanced non-small cell lung cancer (NSCLC). Because S-1 shows synergistic effects with radiation, we conducted a phase I study to evaluate the maximum tolerated doses (MTDs), recommended doses (RDs), and dose-limiting toxicities (DLTs) of cisplatin and S-1 when combined with concurrent thoracic radiation (total dose of 60 Gy with 2 Gy per daily fraction) in patients with locally advanced NSCLC. Chemotherapy consisted of two 4-week cycles of cisplatin administered on days 1 and 8, and S-1 administered on days 1-14. S-1/cisplatin dosages (mg/m(2)/day) were escalated as follows: 60/30, 60/40, 70/40, 80/40 and 80/50. Twenty-two previously untreated patients were enrolled. The MTDs and RDs for S-1/cisplatin were 80/50 and 80/40, respectively. DLTs included febrile neutropaenia, thrombocytopaenia, bacterial pneumonia and delayed second cycle of chemotherapy. No patient experienced radiation pneumonitis>grade 2 and only one patient experienced grade 3 radiation oesophagitis. The overall response rate was 86.4% with a median survival time of 24.4 months. These results indicate that combination cisplatin-S-1 chemotherapy with concurrent thoracic radiation would be a feasible treatment option and a phase II study is currently under way.

    S-1, an oral 5-fluorouracil derivative, is effective against advanced non-small cell lung cancer (NSCLC) with mild toxicity and synergistic effects with radiation in preclinical trials. In this phase I study, we evaluated the dose-limiting toxicity and recommended dose of S-1 for a future phase II study when administered concurrently with thoracic radiation (total dose of 60 Gy at 2 Gy per daily fraction) in elderly patients (>75 years old) with localized advanced NSCLC. S-1 was administered on days 1-14 and 29-42 at the following dosages: 60, 70, and 80 mg/m(2)/day. Twenty-two previously untreated patients were enrolled in this study. Dose-limiting toxicity included febrile neutropenia, thrombocytopenia, stomatitis, and pneumonitis. One patient had grade 5 radiation pneumonitis. No other patient experienced radiation pneumonitis or esophagitis exceeding grade 2. The recommended dose for S-1 was determined to be 80 mg/m(2)/day, which produced an overall response rate of 75% (n=12). The median progression-free survival time was 11.5 months (95% confidence interval: 7.1-15.8 months) with a median follow-up time of 27.9 months. These results indicate that concurrent treatment with S-1 and thoracic radiation is a feasible option for NSCLC in the elderly. A phase II study is currently under way.

    Full Text Available Background and objectives It has been proven that epigermal growth factor receptor (EGFR signal pathway plaied an important role in the oncogenesis and development of non-small cell lung cancer (NSCLC. EGFR tyrosine kinase inhibitors (EGFR-TKIs are currently investigated in the treatment of NSCLC. It was suggested in previous studies that the EGFR gene mutations were correlated with the response to EGFR-TKIs therapy and prognosis of NSCLC. We studied the role of EGFR gene mutations in response to two kinds of TKIs therapy and prognosis of NSCLC in this study. Methods The tissue samples of 59 advanced NSCLC patients (34 patients receiving Gefitinib monotherapy and 25 patients receiving Erlotinib monotherapy were collected, and patient charts were reviewed. The mutations in exons 19 and 21 of EGFR gene were detected by PCR-PAGE and PCR-RFLP respectively. The sequences of interested fragments were verified by direct sequencing. Relationship between EGFR mutation and response to TKIs therapy was analyzed with X^2 test. Results EGFR gene mutations were identified in 22 of 59 samples (37.3%. EGFR gene mutation rate was significantly higher in female, non-smoker and patients with adenocarcinoma than in others (50% vs 18.9%, P0.05. Conclusions EGFR gene mutation occurs more frequently in female, non-smoker and patients with adenocarcinoma. In patients with advanced NSCLC, EGFR mutation is associated with good response to EGFR-TKIs 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.

    Both platinum-based doublet chemotherapy (PBC) and epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) prolong the survival of patients with advanced non-small cell lung cancer (NSCLC). In early studies, most patients underwent PBC as first-line treatment, but not all patients could afford EGFR-TKIs as second-line treatment. To understand the impact of PBC and EGFR-TKIs on NSCLC prognosis, we evaluated the association between the receipt of both regimens and overall survival (OS). Using MEDLINE and EMBASE, we identified prospective, randomized, controlled phase III clinical trials in advanced NSCLC that met the inclusion criteria: in general population with advanced NSCLC, the percentage of patients treated with both PBC and EGFR-TKIs was available in the trial and OS was reported. After collecting data from the selected trials, we correlated the percentage of patients treated with both PBC and EGFR-TKIs with the reported OS, using a weighted analysis. Fifteen phase III clinical trials-involving 11,456 adult patients in 32 arms-were included in the analysis, including 6 trials in Asian populations and 9 in non-Asian (predominantly Caucasian) populations. The OS was positively correlated with the percentage of patients treated with both PBC and EGFR-TKIs (r = 0.797,P < 0.001). The correlation was obvious in the trials in Asian populations (r = 0.936,P < 0.001) but was not statisticaly significant in the trials in predominantly Caucasian populations (r = 0.116,P = 0.588). These results suggest that treatment with PBC and EGFR-TKIs may provide a survival benefit to patients with advanced NSCLC, highlighting the importance of having both modalities available for therapy.

According to published meta-analyses, no significant efficacy differences have been demonstrated between erlotinib and afatinib. However, the incidence of EGFR–TKI-related adverse events (AEs was lower with erlotinib. This study compares the cost of management of the AEs associated with these two drugs from the perspective of the Spanish National Health System (NHS.Methods: The frequency of AEs was established from a recently published meta-analysis. In Spain, the daily cost of both drugs can be considered similar; as a result, only the costs of management of the AEs were considered. Costs and resource utilization in the management of the AEs were estimated by a panel of Spanish oncologists and from studies previously carried out in Spain. A probabilistic analysis was performed based on a Monte Carlo simulation.Results: The model generated 1,000 simulations. The total cost per patient treated with erlotinib and afatinib was €657.44 and €1,272.15, respectively. With erlotinib, the cost per patient and per AE of grades ≤2 and ≥3 was €550.86 and €106.58, respectively, whereas the cost with afatinib was €980.63 and €291.52, respectively. The reduction in the number of AEs with erlotinib could avoid a mean cost for the NHS of €614.71 (95% CI:

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

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

    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.

    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.

    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.

    Full Text Available Abstract Background 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. Methods 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. Results 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. Conclusions These results indicate that gene-guided maintenance therapy with gefitinib with the GPAP might be a cost-effective treatment option.

    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.

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.

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.

    A platinum-based two-drug regimen is currently the standard of care for patients with advanced non-small-cell lung cancer (NSCLC). However, chemotherapy-induced side effects still remain a significant clinical problem. Astragalus polysaccharide (APS) is a polysaccharide isolated from the radix of astragalus membranaceus, a commonly used herbal compound in traditional Chinese medicine. APS was reported to increase tumor response, stabilize and improve performance status, and reduce chemotherapy toxicity. We designed this trial to determine whether APS injection integrated with vinorelbine and cisplatin (VC) offered an improved QOL over VC for patients with advanced NSCLC. Secondary objectives were tumor response, toxicity, and survival results. One hundred thirty-six patients with histologically or cytologically confirmed NSCLC were enrolled in this study from May 2008 to March 2010. Patients were randomized to receive either VC (VC arm) or VC combined with APS (VC-APS arm). The objective response rate of was 42.64% in the VC-APS arm and 36.76% in the VC arm. The difference was not statistically significant (P = 0.483). Median survival time was 10.7 and 10.2 months (P = 0.76) in VC-APS arm and VC arm, with 1-year survival rates of 35.3 and 32.4% (P = 0.717), respectively. After 3 cycles of treatment, there were significant differences in the overall patient QOL (P = 0.003), physical function (P = 0.01), fatigue (P pain (P = 0.007), and loss of appetite (P = 0.023) between the two study groups. In summary, we have proved that the treatment of APS integrated with VC had significantly improved QOL in patients with advanced NSCLC compared with VC alone.

    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.

    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.

    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.

    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.

    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.

    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.

    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

    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.

    The study aims to investigate the role of {sup 18}F-alfatide positron emission tomography/computed tomography (PET/CT) in predicting the short-term outcome of concurrent chemoradiotherapy (CCRT) in patients with advanced non-small cell lung cancer (NSCLC). Eighteen patients with advanced NSCLC had undergone {sup 18}F-alfatide PET/CT scans before CCRT and PET/CT parameters including maximum and mean standard uptake values (SUV{sub max}/SUV{sub mean}), peak standard uptake values (SUV{sub peak}) and tumor volume (TV{sub PET} and TV{sub CT}) were obtained. The SUV{sub max} of tumor and normal tissues (lung, blood pool and muscle) were measured, and their ratios were denoted as T/NT (T/NT{sub lung}, T/NT{sub blood} and T/NT{sub muscle}). Statistical methods included the Two-example t test, Wilcoxon rank-sum test, Receiver-operating characteristic (ROC) curve analysis and logistic regression analyses. We found that SUV{sub max}, SUV{sub peak}, T/NT{sub lung}, T/NT{sub blood} and T/NT{sub muscle} were higher in non-responders than in responders (P = 0.0024, P = 0.016, P < 0.001, P = 0.003, P = 0.004). According to ROC curve analysis, the thresholds of SUV{sub max}, SUV{sub peak}, T/NT{sub lung}, T/NT{sub blood} and T/NT{sub muscle} were 5.65, 4.46, 7.11, 5.41, and 11.75, respectively. The five parameters had high sensitivity, specificity and accuracy in distinguishing non-responders and responders. Multivariate logistic regression analyses showed that T/NT{sub lung} was an independent predictor of the short-term outcome of CCRT in patients with advanced NSCLC (P = 0.032). {sup 18}F-alfatide PET/CT may be useful in predicting the short-term outcome of CCRT in patients with advanced NSCLC.

    Full Text Available Background and objective DNA repair gene polymorphisms can be used to predict the sensitivity of platinum-based chemotherapy. Thus, such polymorphisms are important for the individual treatment of non-small cell lung cancer (NSCLC. The aim of this study is to investigate the relationship between X-ray repair cross complementing protein 1 (XRCC1 and X-ray repair cross complementing protein 3 (XRCC3 gene polymorphisms and the chemosensitivity of platinum-based chemotherapy in patients with advanced NSCLC. Methods Genomic DNA were extracted from the sera of a total of 130 patients with advanced NSCLC who received platinum-based chemotherapy. XRCC1 Arg194 Trp, Arg399 Gln, and XRCC3 Thr241 Met were genotyped using the polymerase chain reaction-restriction fragment length polymorphism method, and the relationship between XRCC1 and XRCC3 polymorphisms and chemotherapy sensitivity was analyzed. Results A total of 130 patients with advanced NSCLC received platinum-based chemotherapy, with an overall response rate of 33.8% after two chemotherapy cycles. The XRCC1 194 and 399 genetic polymorphisms, but not XRCC3 241, were found to be related to the chemosensitivity. The objective response rate of the patients with at least one XRCC1 194 Trp allele was 2.5 times higher than that of Arg/Arg genotype carriers (42.1% vs 22.2%, OR=2.545, 95%CI: 1.159-5.590, P=0.020. The objective response rate of the XRCC1 399 Arg/Arg genotype carriers was significantly higher than that of the patients with at least one Gln allele (45.5% vs 21.9%, OR=0.336, 95%CI: 0.156-0.722, P=0.005. Combined effects between XRCC1 194 and XRCC1 399 were observed. The objective response rate of the patients with at least one XRCC1 194 Trp allele and a 399 Arg/Arg genotype was significantly higher than that of patients with 194 Arg/Arg and 399 Arg/Gln genotypes (44.4% vs 18.8%, OR=3.467, 95%CI: 1.223-9.782, P=0.019.

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.

    Summary Introduction The primary objective of this phase II trial was to evaluate the efficacy and tolerability of vorinostat and bortezomib as third-line therapy in advanced non-small cell lung cancer (NSCLC) patients. Methods Eligibility criteria included recurrent/metastatic NSCLC, having received 2 prior systemic regimens, and performance status 0–2. Patients took vorinostat 400 mg PO daily days 1–14 and bortezomib 1.3 mg/m2 IV day 1, 4, 8 and 11 in a 21-day cycle. Primary endpoint was 3-month progression free survival (3m-PFS), with a goal of at least 40 % of patients being free of progression at that time point. This study followed a two-stage minimax design. Results Eighteen patients were enrolled in the first stage. All patients had two prior lines of treatment. Patients received a median of two treatment cycles (range: 1–6) on study. There were no anti-tumor responses; stable disease was observed in 5 patients (27.8 %). Median PFS was 1.5 months, 3m-PFS rate 11.1 %, and median overall survival 4.7 months. The most common grade 3/4 toxicities were thrombocytopenia and fatigue. Two patients who had baseline taxane-related grade 1 peripheral neuropathy developed grade 3 neuropathy. The study was closed at its first interim analysis for lack of efficacy. Conclusions Bortezomib and vorinostat displayed minimal anti-tumor activity as third-line therapy in NSCLC. We do not recommend this regimen for further investigation in unselected patients. PMID:23728919

    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.

    Grade {>=}3 radiation pneumonitis (RP) is generally severe and life-threatening. Predictors of grade {>=}2 are usually used for grade {>=}3 RP prediction, but it is unclear whether these predictors are appropriate. In this study, predictors of grade {>=}2 and grade {>=}3 RP were investigated separately. The increased risk of severe RP in elderly patients compared with younger patients was also evaluated. Material and methods: A total of 176 consecutive patients with locally advanced non-small cell lung cancer were followed up prospectively after three-dimensional conformal radiotherapy. RP was graded according to Common Terminology Criteria for Adverse Events version 3.0. Results: Mean lung dose (MLD), mean heart dose, ratio of planning target volume to total lung volume (PTV/Lung), and dose-volume histogram comprehensive value of both heart and lung were associated with both grade {>=}2 and grade {>=}3 RP in univariate analysis. In multivariate logistic regression analysis, age and MLD were predictors of both grade {>=}2 RP and grade {>=}3 RP; receipt of chemotherapy predicted grade {>=}3 RP only; and sex and PTV/Lung predicted grade {>=}2 RP only. Among patients who developed high-grade RP, MLD and PTV/Lung were significantly lower in patients aged {>=}70 years than in younger patients (p<0.05 for both comparisons). Conclusions: The predictors were not completely consistent between grade {>=}2 RP and grade {>=}3 RP. Elderly patients had a higher risk of severe RP than younger patients did, possibly due to lower tolerance of radiation to the lung.

    Full Text Available BACKGROUND: A lot of studies have investigated the correlation between x-ray repair cross-complementing group 3 (XRCC3 Thr241Met polymorphism and clinical outcomes in non-small cell cancer (NSCLC, while the conclusion is still conflicting. MATERIALS AND METHODS: We conducted this meta-analysis to evaluate the predictive value of XRCC3 Thr241Met polymorphism on response and overall survival of patients with NSCLC. Pooled odds ratios (ORs and hazard ratios (HRs and corresponding 95% confidence intervals (95% CIs were used to estimate the association strength. RESULTS: A total of 14 eligible studies with 2828 patients were identified according to our inclusion criteria. Meta-analysis results showed that carriers of the variant 241Met allele were significantly associated with good response, compared with those harboring the wild 241Thr allele (Met vs. Thr, OR = 1.453, 95% CI: 1.116-1.892, Pheterogeneity = 0.968 and ThrMet+MetMet vs. ThrThr, OR = 1.476, 95% CI: 1.087-2.004, Pheterogeneity = 0.696. This significant association was observed in Caucasian population but not in Asian population. On the other hand, there was no significant association of XRCC3 Thr241Met polymorphism with survival (ThrMet+MetMet vs. ThrThr, HR = 1.082, 95% CI: 0.929-1.261, Pheterogeneity = 0.564, and there was no difference between Asian and Caucasian population. CONCLUSIONS: These findings suggest a predictive role of XRCC3 Thr241Met polymorphism on response to platinum-based chemotherapy in patients with advanced NSCLC. Additionally, we first report that the XRCC3 Thr241Met polymorphism is associated with response to platinum-based chemotherapy and highlights the prognostic value of the XRCC3 Thr241Met polymorphism.

    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.

    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.

    Full Text Available BACKGROUND: Maintenance gefitinib significantly prolonged progression-free survival (PFS compared with placebo in patients from eastern Asian with locally advanced/metastatic non-small-cell lung cancer (NSCLC after four chemotherapeutic cycles (21 days per cycle of first-line platinum-based combination chemotherapy without disease progression. The objective of the current study was to evaluate the cost-effectiveness of maintenance gefitinib therapy after four chemotherapeutic cycle's stand first-line platinum-based chemotherapy for patients with locally advanced or metastatic NSCLC with unknown EGFR mutations, from a Chinese health care system perspective. METHODS AND FINDINGS: A semi-Markov model was designed to evaluate cost-effectiveness of the maintenance gefitinib treatment. Two-parametric Weibull and Log-logistic distribution were fitted to PFS and overall survival curves independently. One-way and probabilistic sensitivity analyses were conducted to assess the stability of the model designed. The model base-case analysis suggested that maintenance gefitinib would increase benefits in a 1, 3, 6 or 10-year time horizon, with incremental $184,829, $19,214, $19,328, and $21,308 per quality-adjusted life-year (QALY gained, respectively. The most sensitive influential variable in the cost-effectiveness analysis was utility of PFS plus rash, followed by utility of PFS plus diarrhoea, utility of progressed disease, price of gefitinib, cost of follow-up treatment in progressed survival state, and utility of PFS on oral therapy. The price of gefitinib is the most significant parameter that could reduce the incremental cost per QALY. Probabilistic sensitivity analysis indicated that the cost-effective probability of maintenance gefitinib was zero under the willingness-to-pay (WTP threshold of $16,349 (3 × per-capita gross domestic product of China. The sensitivity analyses all suggested that the model was robust. CONCLUSIONS: Maintenance gefitinib

    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.

    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

    Objectives Epidermal growth factor receptor–tyrosine kinase inhibitors (EGFR-TKIs) are an established treatment for advanced non-small cell lung cancer (NSCLC) with EGFR mutation. According to published meta-analyses, no significant efficacy differences have been demonstrated between erlotinib and afatinib. However, the incidence of EGFR–TKI-related adverse events (AEs) was lower with erlotinib. This study compares the cost of management of the AEs associated with these two drugs from the perspective of the Spanish National Health System (NHS). Methods The frequency of AEs was established from a recently published meta-analysis. In Spain, the daily cost of both drugs can be considered similar; as a result, only the costs of management of the AEs were considered. Costs and resource utilization in the management of the AEs were estimated by a panel of Spanish oncologists and from studies previously carried out in Spain. A probabilistic analysis was performed based on a Monte Carlo simulation. Results The model generated 1,000 simulations. The total cost per patient treated with erlotinib and afatinib was €657.44 and €1,272.15, respectively. With erlotinib, the cost per patient and per AE of grades ≤2 and ≥3 was €550.86 and €106.58, respectively, whereas the cost with afatinib was €980.63 and €291.52, respectively. The reduction in the number of AEs with erlotinib could avoid a mean cost for the NHS of €614.71 (95% CI: €342.57–881.29) per patient. Conclusion In advanced EGFR mutation-positive NSCLC patients, first-line treatment with erlotinib could reduce health care costs for the NHS, due to a decrease in the AE rate compared with afatinib. In long-term treatments, the avoidance of complications and the lowering of costs associated with the management of AEs are relevant factors that contribute to the sustainability of the health system.

    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.

    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 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 Epidermal growth factor receptor (EGFR) mutations can predict tumor response to tyrosine kinase inhibitors (TKIs). Detecting EGFR mutations in plasma DNA samples in patients with advanced non-small cell lung cancer is challenging and promising. We compared three methods for detecting plasma EGFR mutations, including direct DNA sequencing, denaturing high-performance liquid chromatography (DHPLC) and Scorpions Amplification Refractory Mutation System (Scorpions ARMS).Methods Plasma DNA samples from 73 patients with stage ⅢB to Ⅳ adenocarcinoma were analyzed for EGFR mutations in exons 19 (deletion mutation) and 21(L858R mutation) using direct DNA sequencing, DHPLC and Scorpions ARMS. Sensitivities of the three methods were compared and the relationship between EGFR mutations and patients'survival was analyzed.Results In 73 patients, we detected EGFR mutations in 5 samples (6.9%) by direct DNA sequencing, in 22 samples (30.1%) by DHPLC, and in 28 samples (38.4%) by Scorpions ARMS. EGFR mutations were found in 13 samples in exon 19 and in 9 samples in exon 21 by DHPLC, while we found mutations in 15 samples in exon 19 and in 13 samples in exon 21 by Scorpions ARMS. Among the 73 patients, there was 90.4% concordance between DHPLC and Scorpions ARMS (66/73, K=0.79, P=0.07). Of the 73 patients, 46 patients were treated with gefitinib, including 18 patients with mutations and 28 patients without mutations as determined by Scorpions ARMS. The 18 patients with mutations had a significantly longer progression-free survival (PFS) time (median PFS was 21.0 months) than the 28 patients without mutations (median PFS was 7.0 months) (P=0.022).Conclusions Among the three methods for detecting EGFR mutations in plasma DNA samples of patients with advanced lung adenocarcinoma, direct gene sequencing had the lowest sensitivity, while Scorpion ARMS showed the highest mutation detecting capability. DHPLC is slightly less sensitive than Scorpion ARMS. EGFR

    Full Text Available Abstract Background 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. Methods 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. Results 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

    The presence of activating gene mutations in the epidermal growth factor receptor of non-small cell lung cancer patients is predictive (improved progression-free survival and improved response rate) when treated with small molecule tyrosine kinase inhibitors such as gefitinib, erlotinib and afatinib. The two most common mutations that account for greater than 85% of all EGFR gene mutations are in-frame deletions in exon 19 (LREA deletions) and substitution in exon 21 (L858R). Exon 18 mutations occur much less frequently at about 4% of all EGFR gene mutations. Together, exon 19 deletion and exon 21 L858R gene substitution are present in about 10% of Caucasian patients and 20-40% of Asian patients with non-small cell lung cancer. T790M gene mutation at exon 20 is associated with acquired resistance to epidermal growth factor receptor tyrosine kinase inhibitors. Early studies showed that activating EGFR gene mutations are most common in patients with adenocarcinoma histology, women, never smokers and those of Asian ethnicity. A recent multi-center phase III trial suggested that frontline epidermal growth factor receptor tyrosine kinase inhibitor therapy with afatinib is associated with improved progression-free survival compared to chemotherapy regardless of race. Moreover, guidelines now suggest EGFR gene mutation testing should be conducted in all patients with lung adenocarcinoma or mixed lung cancers with an adenocarcinoma component, regardless of characteristics such as smoking status, gender or race. The success of targeted therapies in non-small cell lung cancer patients has changed the treatment paradigm in metastatic non-small cell lung cancer. However, despite a durable response of greater than a year, resistance to epidermal growth factor receptor tyrosine kinase inhibitors inevitably occurs. This mini-review describes the clinically relevant EGFR gene mutations and the efficacy/toxicity of small molecule epidermal growth factor receptor tyrosine kinase

    Cetuximab is a chimeric human-mouse anti-EGF receptor monoclonal antibody. In Phase I studies, no dose-limiting toxicities were observed with cetuximab as a single agent or combined with chemotherapy; pharmacokinetic and pharmacodynamic analyses supported 250 mg/m(2) weekly administration. Skin toxicity, diarrhea and fatigue were the most common toxicities. The positive results obtained in Phase II trials in patients with advanced non-small-cell lung cancer prompted two randomized Phase III trials evaluating cetuximab in addition to first-line chemotherapy. Both trials showed a small benefit in overall survival for the experimental treatment, which was considered insufficient by the EMA for marketing approval. However, a subgroup analysis of the FLEX Phase III trial recently demonstrated a larger survival benefit from the experimental treatment in patients with high immunohistochemical EGF receptor expression. This finding, if confirmed prospectively, could represent a new opportunity for positioning cetuximab into the standard treatment of advanced non-small-cell lung carcinoma.

    Full Text Available BACKGROUND: Several EGFR-tyrosine kinase inhibitors (EGFR-TKIs including erlotinib, gefitinib, afatinib and icotinib are currently available as treatment for patients with advanced non-small-cell lung cancer (NSCLC who harbor EGFR mutations. However, no head to head trials between these TKIs in mutated populations have been reported, which provides room for indirect and integrated comparisons. METHODS: We searched electronic databases for eligible literatures. Pooled data on objective response rate (ORR, progression free survival (PFS, overall survival (OS were calculated. Appropriate networks for different outcomes were established to incorporate all evidences. Multiple-treatments comparisons (MTCs based on Bayesian network integrated the efficacy and specific toxicities of all included treatments. RESULTS: Twelve phase III RCTs that investigated EGFR-TKIs involving 1821 participants with EGFR mutation were included. For mutant patients, the weighted pooled ORR and 1-year PFS of EGFR-TKIs were significant superior to that of standard chemotherapy (ORR: 66.6% vs. 30.9%, OR 5.46, 95%CI 3.59 to 8.30, P<0.00001; 1-year PFS: 42.9% vs. 9.7%, OR 7.83, 95%CI 4.50 to 13.61; P<0.00001 through direct meta-analysis. In the network meta-analyses, no statistically significant differences in efficacy were found between these four TKIs with respect to all outcome measures. Trend analyses of rank probabilities revealed that the cumulative probabilities of being the most efficacious treatments were (ORR, 1-year PFS, 1-year OS, 2-year OS: erlotinib (51%, 38%, 14%, 19%, gefitinib (1%, 6%, 5%, 16%, afatinib (29%, 27%, 30%, 27% and icotinib (19%, 29%, NA, NA, respectively. However, afatinib and erlotinib showed significant severer rash and diarrhea compared with gefitinib and icotinib. CONCLUSIONS: The current study indicated that erlotinib, gefitinib, afatinib and icotinib shared equivalent efficacy but presented different efficacy-toxicity pattern for EGFR

    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.

    Full Text Available Introduction: Lung cancer is the third most frequent neoplastic tumour in Spain, with around 27 000 new cases diagnosed per year; 80-95% of these are non-small-cell cancer (NSCLC, and the majority of cases are diagnosed in advanced stages of the disease, and for this reason it is one of the oncologic conditions with higher mortality rates (21.4% mean survival at 5 years. The main treatment regimens used for first-line treatment of NSCLC are: isplatin/pemetrexed (cis/pem, cisplatin/gemcitabine/ bevacizumab (cis/gem/bev, and carboplatin/paclitaxel/ bevacizumab (carb/pac/bev. The objective of this study was to evaluate the cost-effectiveness ratio of antineoplastic 1st line NSCLC treatment regimens, from the point of view of hospital management. Methodology: A cost-efficacy mathematical model was prepared, based on a decision tree. The efficacy variable was Progression Free Survival, obtained from the PARAMOUNT, AVAIL and SAIL Phase III clinical trials. The study was conducted from the perspective of the hospital management, considering only the direct costs of drug acquisition. A deterministic sensitivity analysis was conducted to confirm the robustness of outcomes. Results: The PFS obtained in clinical trials with cis/pem, cis/ gem/bev and carb/pac/bev was: 6.9, 6.7 and 6.2 months, respectively. Based on our model, the mean cost of treatment per patient for these regimens was: 19 942 €, 15 594 € and 36 095 €, respectively. The incremental cost-effectiveness ratio per month of additional PFS between cis/pem and cis/gem/bev was 19 303 €. Estimating a 30% reduction in acquisition costs for pemetrexed (Alimta®Eli Lilly Nederland B.V., due to the forthcoming launch of generic medications, the cis/pem treatment would become the predominant alternative for 1st line treatment of NSCLC patients, by offering the best health results at a lower cost.

    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

    Full Text Available Nintedanib is a triple angiokinase inhibitor that has been approved by the European Agency Medicines (EMA in combination with docetaxel for the treatment of adult patients with locally advanced, metastatic or locally recurrent non small cell lung cancer (NSCLC of adenocarcinoma tumour histology, after first-line chemotherapy. In LUME-Lung 1 clinical trial, the combination of nintedanib plus docetaxel vs. placebo plus docetaxel improved progression free survival (PFS in NSCLC patients, and improved overall survival in the population of adenocarcinoma patients, particularly in those with progression within 9 months after first line treatment initiation, median 10.9 months ( [95% CI 8.5–12.6] vs. 7.9 months [6.7–9.1]; HR 0.75 [95% CI 0.60–0.92], p=0.0073. The toxicity profile of the combination included a higher incidence of neutropenia, gastro-intestinal (GI disorders, and liver enzyme elevations; however, this did not cause a detrimental effect on patient quality of life. According to data from the clinical trial mentioned, the addition of nintedanib to docetaxel would lead to an estimated incremental cost-effectiveness ratio (ICER per year of life with PFS in the overall population of 134,274.47 € (notified price. In the adenocarcinoma population per each life of year gained (LYG, the ICER of adding nintedanib to docetaxel would be 40,886.14 €; while by implementing a sensitivity analysis with a 25% discount in the drug price, the cost per LYG would be 32,364.05 €, and would place it close to the threshold of cost-effectiveness usually considered acceptable in our setting. In view of efficacy and safety results the proposed positioning is to recommend its inclusion in the Hospital Formulary only for adult patients with metastatic or locally recurrent NSCLC with adenocarcinoma histology after first line chemotherapy, with progression < 9 months from the initiation of first line treatment, taking into account the inclusion and

    Full Text Available Patrick J Richard, Ramesh Rengan Department of Radiation Oncology, University of Washington, Seattle, WA, USA Abstract: The oligometastatic disease theory was initially described in 1995 by Hellman and Weichselbaum. Since then, much work has been performed to investigate its existence in many solid tumors. This has led to subclassifications of stage IV cancer, which could redefine our treatment approaches and the therapeutic outcomes for this historically “incurable” entity. With a high incidence of stage IV disease, non-small-cell lung cancer (NSCLC remains a difficult cancer to treat and cure. Recent work has proven the existence of an oligometastatic state in NSCLC in terms of properly selecting patients who may benefit from aggressive therapy and experience long-term overall survival. This review discusses the current treatment approaches used in oligometastatic NSCLC and provides the evidence and rationale for each approach. The prognostic factors of many trials are discussed, which can be used to properly select patients for aggressive treatment regimens. Future advances in both molecular profiling of NSCLC to find targetable mutations and investigating patient selection may increase the number of patients diagnosed with oligometastatic NSCLC. As this disease entity increases, it is of utmost importance for oncologists treating NSCLC to be aware of the current treatment strategies that exist and the potential advantages/disadvantages of each.

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.

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.

    @@ 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).

    The relation between dietary intake and metabolic profile in non-small cell lung cancer (NSCLC) was evaluated. Patients with NSCLC were recruited and their caloric requirement and resting energy expenditure (REE) were calculated using the Harris-Benedict equation and Katch-McArdle formula respectively. Hypermetabolic state was defined as REE more than 10% above the basal metabolic rate (BMR). Body composition parameters were calculated by bioelectric impedance method. The 24-h dietary intake method and Malnutrition Universal Screening Tool assessed nutritional intake. One hundred and forty-eight subjects were included (87% males). Of these, 46.6% subjects were hypermetabolic and 31% cachexic, with lower calorie and protein intakes than recommended, although per cent of total energy derived from protein, fat and carbohydrates were similar. Hypermetabolic patients had lower BMI, though the per cent deficit in energy and protein consumption was similar. Cachexia was associated with lower BMR but not with deficit in energy or protein consumption. No correlation was seen between dietary intake and body composition parameters. The calorie and protein intake of NSCLC patients is lower than recommended. The discordance between elevated REE and dietary intake implies that the relationship between increased energy demands and food intake may be altered.

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 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.

    STEALTH cisplatin (SPI-77) is a liposomal formulation of cisplatin that has activity in animal models of non small-cell lung cancer (NSCLC). Vinorelbine has documented clinical activity in NSCLC. The purpose of this study was to determine the dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) of SPI-77 when administered in combination with a fixed dose of vinorelbine to patients with stage IIIB or IV NSCLC refractory to or recurrent following previous chemotherapy. SPI-77 was given on day 1 in combination with vinorelbine at a fixed dose of 25 mg/m2 on days 1 and 8 of a 3-week treatment cycle. Dose escalation of SPI-77 progressed as follows: 20, 40, 80, 100, 120, and 140 mg/m2. Twenty patients were entered (11 men and nine women; median age, 63 years). Sixty-four complete cycles of therapy were administered, and 19 of 20 patients completed at least 1 cycle of combination chemotherapy. Neutropenia was dose limiting at a SPI-77 dose of 140 mg/m2. Neuropathy and nephrotoxicity were minimal and not dose related. A partial response was observed in three of 17 patients eligible for a response evaluation and response duration ranged from 6 weeks to 5 months. In conclusion, treatment with combination SPI-77 and vinorelbine was well tolerated, and our recommended phase II dose is 120 mg/m2 of SPI-77 in combination with vinorelbine at 25 mg/m2. Activity was observed in this patient population, and additional phase II testing of this regimen in a less extensively pretreated cohort of patients with NSCLC is indicated.

    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.

    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.

    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

    Globally, Lung cancer is the leading cause of cancer-related death of high morbidity and mortality with poor prognosis, which needs some more effective and less toxic therapies. hTe immunotherapies offer a novel approach for the treatment of patients with non-small cell lung cancer (NSCLC) in both the adjuvant and palliative disease settings. A number of promising immunotherapies based on different mechanism have now been evaluated showing an increasing response rate. Moreover, further phase II/III clinical trials will be indicated to explore its value. hTese include checkpoint inhibitors (anti-CT-LA4 antibody, anti-PD-1 antibody, anti-PD-L1 antibody), active vaccination (L-BLP25 liposome vaccine, Belagenpumatucel-L vaccine, MAGE-A3 protein vaccine) and adoptive vaccination (CIK cells). hTe purpose of this paper will draw a summary on the theory, clinical trials, toxicity and problems to be solved of the immunotherapies in NSCLC.%肺癌是全球范围内癌性死亡的首要因素,发病率、死亡率高,预后较差,急需开发一种新的高效低毒疗法。作为术后辅助或是姑息治疗手段,免疫治疗为非小细胞肺癌患者提供了一个新的治疗方向。免疫疗法作用机理各不相同,如免疫检测点受体抑制剂(抗CTLA4抗体、抗PD-1抗体、抗PD-L1抗体)、主动性免疫疫苗(L-BLP25脂质体疫苗、Belagenpumatucel-L疫苗、MAGE-A3蛋白疫苗)、过继性免疫疫苗(CIK细胞)等,研究表明免疫治疗非小细胞肺癌肿瘤缓解率较前提高,前景值得期待,II期/III期临床试验亦在进一步探索其临床应用价值。本文就当前非小细胞肺癌免疫疗法原理、临床试验、不良反应及待解决问题作一概述。

    Objective: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. hTe mechanisms of resistance are complicated. hTe lack of established therapeutic options for patients atfer a failed EGFR-TKI treatment poses a great challenge to physicians in managing this group of lung cancer patients. hTis study evaluates the inlfuence of EGFR-TKI retreatment following chemotherapy atfer failure of initial EGFR-TKI within at least 6 months on NSCLC patients. Methods:hTe data of 27 patients who experienced treatment failure from their initial use of EGFR-TKI within at least 6 months were analyzed. Atfer chemotherapy, the patients were retreated with EGFR-TKI (geiftinib 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. Results: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). hTe disease control rate (DCR) was 85.2%(95%CI:62%-94%). hTe 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. hTe 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. hTe DCR was 85.7%, and the mPFS was 9.5 months. Signiifcant difference was found between the two

    Full Text Available Abstract Background Glutamine (Gln supplementation during concurrent chemoradiotherapy (C-CRT effectively reduces the incidence and severity of acute radiation-induced esophagitis (RIE. However, there are concerns that Gln might stimulate tumor growth, and therefore negatively impact the outcomes of anticancer treatment. We retrospectively investigated the effect of co-administration of oral Gln during C-CRT on survival outcomes of patients with stage IIIB non-small cell lung carcinoma (NSCLC. We additionally evaluated role of oral Gln in preventing C-CRT-induced weight change, acute and late toxicities. Methods The study included 104 patients: 56 (53.8% received prophylactic powdered Gln (Gln+ orally at a dose of 10 g/8 h and 48 (46.2% did not receive Gln (Gln- and served as controls. The prescribed radiation dose to the planning target volume was 66 Gy in 2-Gy fractions. Primary endpoints of progression-free survival (PFS, local/regional progression-free survival (LRPFS, and overall survival (OS were correlated with status of Gln supplementation. Results Oral Gln was well tolerated except for mild nausea/vomiting in 14 (25.0% patients. There was no C-CRT-related acute or late grade 4–5 toxicity. Administration of Gln was associated with a decrease in the incidence of grade 3 acute radiation-induced esophagitis (RIE (7.2% vs. 16.7% for Gln+ vs. Gln-; p=0.02 and late-RIE (0% vs. 6.3%; p=0.06, a reduced need for unplanned treatment breaks (7.1% vs. 20.8%; p=0.04, and reduced incidence of weight loss (44.6% vs. 72.9%; p=0.002. At a median follow-up of 24.2 months (range 9.2-34.4 the median OS, LRPFS, and PFS for Gln+ vs. Gln- cohorts were 21.4 vs. 20.4 (p=0.35, 14.2 vs.11.3 (p=0.16, and 10.2 vs. 9.0 months (p=0.11, respectively. Conclusion In our study, supplementation with Gln during C-CRT had no detectable negative impact on tumor control and survival outcomes in patients with Stage IIIB NSCLC. Furthermore, Gln appeared to have a beneficial

    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.)

    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

    Objective The aim of the study was to observe the influence of autologous cytokine-induced kil er cel (CIK) treatment on the objective ef icacy and safety of gefitinib in advanced non-smal cel lung cancer (NSCLC). Methods Sixty-six patients with NSCLC received gefitinib as second-line treatment. They were randomly divided into 2 groups, and informed consent forms were signed before grouping. Gefitinib was administrat-ed to the control group, and autologous CIK treatment was added to the observation group. The objective treatment and adverse reactions were evaluated in both groups. Results The objective response rate (ORR) and the disease control rate (DCR) of the observation group were slightly higher than those of the control group, although no statistical dif erences were found between the 2 groups (P > 0.05). The incidences of diarrhea, fatigue, anorexia, oral ulcers, and myelosuppression in the observation group were much lower than those in the control group (P 0.05). Conclusion Autologous CIK in combination with gefitinib is ef ective as second-line treatment for ad-vanced NSCLC, and can significantly reduce adverse reactions and improve the objective ef icacy.

    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

    This phase 2 study assessed PF-3512676 plus erlotinib in patients with epidermal growth factor receptor-positive advanced non-small cell lung cancer after prior chemotherapy failure. Patients were randomized 1:1 to PF-3512676 (0.20 mg/kg injected subcutaneously once weekly) plus erlotinib (150 mg daily) or erlotinib alone. The primary objective was to estimate progression-free survival (PFS). Patients received PF-3512676 plus erlotinib (n = 18) or erlotinib alone (n = 21). The study was halted because an unplanned interim analysis indicated that large improvement in PFS with addition of PF-3512676 would be unlikely. In the PF-3512676-plus-erlotinib and erlotinib-alone arms, median PFS was 1.6 and 1.7 mo (hazard ratio, 1.00; 95% confidence interval, 0.5-2.0; P = 0.9335), respectively. Salient grade ≥ 3 adverse events in PF-3512676-plus-erlotinib and erlotinib-alone arms were diarrhea (5/0), dyspnea (5/6), fatigue (4/1), other flu-like symptoms (2/0), anemia (2/1), and lymphocytopenia (based on laboratory values, 1/4). Adding PF-3512676 to erlotinib did not show potential for increased progression-free survival over erlotinib alone in patients with advanced recurrent epidermal growth factor receptor-positive non-small cell lung cancer.

    Lung cancer continues to be the leading cause of cancer death worldwide, and non-small cell lung cancer is the most common type of lung cancer. Despite many clinical trials of platinum-based chemotherapy in combination with various drugs, the median survival time of patients with non-small cell lung cancer remains poor. The overall 5-year survival rate of patients with advanced non-small cell lung cancer is approximately 15%, and has improved only marginally in recent years.A recent milestone in this field has been the development of molecular-targeting drugs, among which gefitinib and erlotinib targeting the epidermal growth factor receptor (EGFR) have improved the efficacy of therapy for non-small cell lung cancer.Anti-angiogenetic drug, such as bevacizumab, has been used in the treatment of non-small cell lung cancer. Moreover, the discovery of echinoderm microtubule-associated protein-like 4/anaplastic lymphoma kinase(EMI4-ALK) fusion gene has contributed to the marvelous progress in research of lung cancer. In this review, the drugs used in individualized treatment of advanced non-small cell lung cancer, such as EGFR-tyrosine kinase inhibitors and EMIA-ALK fusion gene inhibitors are introduced.%在世界范围内,肺癌位居所有癌症致死的首位,且其中大部分为非小细胞肺癌.尽管大量有关含铂化疔或联合其他药物的临床研究不断涌现,非小细胞肺癌患者的预后仍然差强人意.晚期非小细胞肺癌患者的5年生存率约为15%,在过去几年中未有明显提高.目前,肺癌治疗领域的主要成就在于靶向治疗的出现,例如针对表皮细胞生长因子受体(EGFR)靶点的吉非替尼和厄罗替尼,以及针对抗血管内皮细胞生长因子(VEGF)的贝伐单抗,均广泛运用于临床.同时,关于棘皮动物微管相关蛋白样/间变淋巴瘤激酶(EML4-ALK)融合基因的研究使得肺癌的治疗又有了新的进展.该文主要对晚期非小细胞肺癌患者个体化治疗

    The main methods to treat locally advanced non-small cell lung cancer are radiotherapy and chemotherapy. The combination of radiotherapy and chemotherapy includes sequential chemoradiotherapy and concurrent chemoradiotherapy. The effectiveness of concurrent chemoradiotherapy is superior to that of sequential chemoradiotherapy, but the toxicity of concurrent chemoradiotherapy increases as well. Continuing to explore new ways which can improve the effectiveness and reduce the toxicity is the current and future direction. [Key words] Carcinoma, non-small cell lung; Radiotherapy; Drug therapy%局部晚期非小细胞肺癌主要的治疗方式是放疗和化疗.放疗与化疗结合分为序贯放化疗和同步放化疗两种.同步放化疗在治疗疗效方面优于序贯治疗,但同时增加了不良反应.继续探索新的提高疗效、降低毒性的方法是目前及未来的研究方向.

    Objective: The purpose of this study was to evaluate the efficacy and safety of concurrent chemoradiotherapy (CCRT) in patients with locally advanced non-small cell lung cancer (LANSCLC). Methods: 83 cases of patients who have been diagnosed for locally advanced NSCLC by determined cytology or pathology were divided into two groups randomly, 42 patients in NP group and 41 patients in EP group. All patients accepted thoracic three-dimensional conformal radiotherapy (3D-CRT) and concurrent either NP chemotherapy in NP group or EP chemotherapy in EP group. 3D-CRT were started on day 1 in the first cycle of chemotherapy. Chemotherapy were carried out for 4 cycles, every cycle was 21 days. Thoracic radiotherapy adopted conventional fractionated irradiation with 15 MeV-X ray, a total dose of 60 Gy. Results: In 83 patients were evaluable, there were 5 cases complete regression to be observed, 29 cases had partial regression (PR), 7 cases with stable disease (SD) and 1 case with progression disease (PD) in NP group. CR 3 cases, PR 27 cases, SD 9 cases and PD 2 cases in EP group. The overall response rate (RR) both NP group and EP group were 80.9%, 73.2%, respectively (P = 0.785).1-, 2-, 3-year survival rate were 90.5%, 69.0%, 28.6% and 82.9%, 51.2%, 21.9%, respectively (P = 0.393). The incidence of leukopenia and thrombocytopenia in NP group was higher than that in the EP group (P < 0.05). Conclusion: CCRT in patients with locally advanced non-small cell lung cancer, 3D-CRT with concurrent NP or EP chemotherapy. 1-, 2-, 3-year overall survival (OS) and average survival time (AST) were not statistically differences, a higher incidence of toxicities were observed in NP group but can be tolerable.

    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). Other clinical features were all

    Photodynamic therapy is increasingly being utilized to treat thoracic malignancies. For patients with early-stage non-small cell lung cancer, photodynamic therapy is primarily employed as an endobronchial therapy to definitely treat endobronchial, roentgenographically occult, or synchronous primary carcinomas. As definitive monotherapy, photodynamic therapy is most effective in treating bronchoscopically visible lung cancers ≤1 cm with no extracartilaginous invasion. For patients with advanced-stage non-small cell lung cancer, photodynamic therapy can be used to palliate obstructing endobronchial lesions, as a component of definitive multi-modality therapy, or to increase operability or reduce the extent of operation required. A review of the available medical literature detailing all published studies utilizing photodynamic therapy to treat at least 10 patients with non-small cell lung cancer is performed, and treatment recommendations and summaries for photodynamic therapy applications are described.

    Several phase III clinical trials had authenticated that the addition of bevacizumab to paclitaxel plus carboplatin or gemcitabine plus cisplatin showed encouraging efficacy as first-line therapy for advanced NSCLC patients. However, the benefits of adding bevacizumab to other chemotherapy regimens in first- or second-line therapy have not been reported. To compare the clinical efficacy and safety of bevacizumab concomitant with chemotherapy regimens in patients with advanced NSCLC as first- or second-line therapy, we retrospectively reviewed the effects of adding bevacizumab to chemotherapy regimens in naive-chemotherapy and pre-chemotherapy patients with advanced non-squamous NSCLC. A total of 79 patients with advanced non-squamous NSCLC received at least two cycles of bevacizumab with chemotherapy between October 2010 and December 2013 were selected. Our primary end points were overall response rate (ORR) and disease control rate (DCR). The secondary objective was overall survival (OS) and safety. Seventy-nine patients were included in this study. Overall response rates at first evaluation (after 2 cycles) were 23.1 % (9/39) and 5.0 % (2/40) in first- and second-line therapy (P = 0.020), respectively. And disease control rates were 84.6 % (33/39) and 50 % (20/40), respectively (P = 0.001). The median OS were 27.2 months (95 % CI 13.3-41.1 months) and 29.6 months (95 % CI 6.7-52.5 months), respectively (P = 0.740). Grade 3-4 adverse events included leukopenia (2/39), and neutropenia (3/39) in first-line therapy versus neutropenia (1/40) and thrombocytopenia (2/40) in second-line treatment. In our experience, combination of bevacizumab and chemotherapy had encouraging anti-tumor efficacy as both first- and second-line therapy.

    HeadHER1/EGFR is known to play a pivotal role in tumorigenesis and is overexpressed in up to 80% of NSCLCs. The study of an Expanded Access Clinical Program of Erlotinib in NSCLC is a phase IV open-label, non-randomized, multicenter trial in patients with advanced (inoperable stage IIIb/IV) NSCLC who were eligible for treatment with erlotinib but had no access to trial participation. Patients for the study from Bosnia and Herzegovina (B&H) were selected from two Clinical centres (Sarajevo and Banja Luka). The aim of study was to evaluated efficacy and tolerability of erlotinib monotherapy in this setting. All patients who received at least one dose of erlotinib and data were entered in the database as of the CRF cut-off date of 14th May 2008 were included in analysis of data (n = 19). This population is defined as the Intent to Treat (ITT) population and includes all patients who had at least one dose of erlotinib regardless of whether major protocol violations were incurred. The findings are consistent with the results of the randomized, placebo-controlled BR.21 study. Indicating that erlotinib is an effective option for patients with advanced NSCLC who are unsuitable for, or who have previously failed standard chemotherapy. In B&H group of patients DCR was almost 84%, and PFS was approximately 24,7 weeks (compared with 44% and 9,7 weeks for erlotinib reported in phase III). Almost three quarter of the patients received erlotinib as their second line of therapy. Overall, erlotinib was well tolerated; there were no patients who withdrew due to a treatment-related AE (mainly rash) and there were few dose reductions. 24% of patients experienced an SAE (most commonly gastrointestinal (GI) disorders).

    A prognostic index for second-line chemotherapy of NSCLC was previously developed, based on individual patient data (IPD) of nine randomized trials. In order to validate the prognostic score in an external dataset, we analysed IPD of a non-inferiority phase III trial comparing vinflunine vs. docetaxel in second-line treatment of advanced NSCLC. Primary endpoint of this analysis was overall survival (OS). The following variables were considered for survival analysis and score calculation: gender, performance status, stage of disease, tumour histology, type of first-line treatment, response to first-line treatment. Cox model, stratified by treatment arm, was used for multivariate analysis. Individual prognostic scores were derived, and patients were divided into 3 categories: 9 (worst). All 551 patients enrolled in the trial had complete information for the calculation of prognostic score. Median OS in the whole group was 6.9 months, with similar efficacy in the two treatment arms. Median OS was 12.9, 6.9 and 3.8 months in the best, intermediate and worst category, respectively. Cox model showed a significant effect comparing intermediate vs. best category (Hazard Ratio 1.79, 95%CI 1.31-2.47, p=0.0003) and comparing worst vs. best category (Hazard Ratio 3.25, 95%CI 2.18-4.83, pmodel was high (0.926), indicating a good discrimination according to the proposed three risk categories. Prognostic ability of our score for candidates to second-line treatment in advanced NSCLC was successfully validated, allowing the identification of subgroups of patients with more vs. less favourable outcome. Prognostic score could be useful in daily decision-making in clinical practise, because a better understanding of factors conditioning life expectancy of patients could greatly help a careful evaluation of risks and benefits associated with therapeutic decisions.

    This multicenter phase II study evaluated, in chemonaive patients with stage IIIB–IV NSCLC, age ⩾70 and with a performance status 0–2, the activity, efficacy and tolerability of planned sequential administration of gemcitabine 1200 mg m−2 on days 1 and 8 every 3 weeks for three courses followed by three cycles of docetaxel 37.5 mg m−2 on days 1 and 8 every 3 weeks, provided there was no evidence of disease progression. A total of 56 patients entered the study. According to intention-to-treat analysis, the objective response rate was 16.0% (95% CI 7.6–28.3%); 23 patients (41.0%) had stable disease and 24 patients (43%) had progressive disease. Five patients who had a stable disease after three courses of gemcitabine obtained a conversion to partial response by docetaxel. Median time to progression was 4.8 months (95% CI 3.6–6.0 months) and median duration of survival was 8.0 months (95% CI 5.6–10.5 months). The 1-year survival rate was 34%. No grade 4 haematological toxicity was observed and grade 3 neutropenia and thrombocytopenia were reported in 5.4 and 3.6% of the patients, respectively. Grade 3/4 mucositis and grade 3 diarrhoea, both occurred in 3.6% of the patients and grade 3 asthenia was observed in 9% of patients. One patient reported a grade 4 skin toxicity. No treatment-related deaths occurred. Sequential gemcitabine and docetaxel is a well-tolerated and effective regimen in elderly advanced NSCLC patients. PMID:18212755

    Objective: To analyze the outcomes of patients who received TKI immediately after the first-line without progression as maintenance treatment (immediate group) vs. those received delayed treatment upon disease progression as second-line therapy (delayed group). Methods: The study included 159 no-small-cell lung cancer (NSCLC) patients who received gefitinib or erlotinib as maintenance treatment in the immediate group (85 patients) or as second-line therapy in the delayed group (74patients). The primary end point was progression-free survival (PFS). EGFR mutation status was detected using denaturing high-performance liquid chromatography (DHPLC). Results: PFS was 17.3 and 16.4 months in the immediate and delayed groups, respectively (hazard ratio [HR],0.99; 95% Confidence Interval [Cl]: 0.69-1.42; P=0.947). In a subgroup analysis that included only patients with EGFR mutation, however, PFS was significantly longer in the immediate group than in the delayed group (HR, 0.48; 95% Cl:0.27-0.85; P=0.012). In patients with wild type EGFR, the risk for disease progression was comparable between the two groups (HR, 1.23; 95% Cl: 0.61-2.51; P=0.564). No significant difference was demonstrated between the immediate and delayed group in terms of the overall survival (OS) (26.1 months vs. 21.6 months, respectively;HR=0.53; 95% Cl: 0.27 to 1.06; P=0.072). There was also no difference in the incidence of adverse events between the two groups. Conclusions: EGFR TKI maintenance improves PFS in patients with EGFR mutation. Prospectively designed clinical studies that compare TKI immediate vs. delayed treatment after first-line chemotherapy upon disease progression are needed.

The SUVmax from early images (SUVmax1 and SUVmax from delayed images (SUVmax2 were recorded and used to calculate the SUVmax changes, including the SUVmax increment (ΔSUVmax and percent change of the SUVmax (%ΔSUVmax. Progression-free survival (PFS and overall survival (OS were determined by the Kaplan–Meier method and were compared with the studied PET parameters, and the clinicopathological prognostic factors in univariate analyses and multivariate analyses were constructed using Cox proportional hazards regression.Results: One hundred and fifteen consecutive patients were reviewed, and the median follow-up time was 12.5 months. The estimated median PFS and OS were 3.8 and 9.6 months, respectively. In univariate analysis, SUVmax1, SUVmax2, ΔSUVmax, %ΔSUVmax, clinical stage, and Eastern Cooperative Oncology Group (ECOG scores were significant prognostic factors for PFS. Similar results were significantly correlated with OS, except %ΔSUVmax. In multivariate analysis, ΔSUVmax and %ΔSUVmax were significant

    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.

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

    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.

    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.

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.

    Full Text Available Biomarker testing has become standard of care for patients diagnosed with non-small cell lung cancer. Although it can be successfully performed in circulating tu-mor cells, at present, the vast majority of investigations are carried out using di-rect tumor sampling, either through aspiration methods, which render most often isolated cells, or tissue sampling, that could range from minute biopsies to large resections. Consequently, pathologists play a central role in this process. Recent evidence suggests that refining NSCLC diagnosis might be clinically signifi-cant, particularly in cases of lung adenocarcinomas (ADC, which in turn, has prompted a new proposal for the histologic classification of such pulmonary neo-plasms. These changes, in conjunction with the mandatory incorporation of biomarker testing in routine NSCLC tissue processing, have directly affected the pathologist’s role in lung cancer work-up. This new role pathologists must play is complex and demanding, and requires a close interaction with surgeons, oncologists, radiologists and molecular pathologists. Pathologists often find themselves as the central figure in the coordination of a process, that involves assuring that the tumor samples are properly fixed, but without disruption of the DNA structure, obtaining the proper diagnosis with a minimum of tissue waste, providing pre-analytical evaluation of tumor samples selected for biomarker testing, which includes assessment of the proportion of tumor to normal tissues, as well as cell viability, and assuring that this entire pro-cess happens in a timely fashion. Therefore, it is part of the pathologist’s respon-sibilities to assure that the samples received in their laboratories, be processed in a manner that allows for optimal biomarker testing. This article goal is to discuss the essential role pathologists must play NSCLC bi-omarker testing, as well as to provide a summarized review of the main NSCLC bi-omarkers of

    Full Text Available Breast and lung cancers are the most common primary neoplasms to manifest with choroidal metastases. The incidence of choroidal metastases from metastatic lung cancer was reported to be 2–6.7%. We report a case of bilateral choroidal metastasis from non-small cell lung cancer. A 59-year-old Caucasian female patient, never a smoker, was diagnosed with stage IV lung adenocarcinoma metastatic to the pleura, bones, and the brain. Her initial scan of the chest showed innumerable soft tissue nodules and mediastinal adenopathy compatible with metastatic disease. Her initial brain MRI showed numerous small enhancing lesions consistent with extensive disease. Unfortunately, during her follow-up visits, she presented with bulge on her left eye. Simultaneously, her follow-up chest scan showed increase in the size of the lung nodules. She continued to have a reasonable performance status at that time, except for mild increase in her dyspnea. The choroidal metastases require a multidisciplinary care and should be among the differential patients with malignancy who present with ocular symptoms.

    Background Icotinib is a small molecule targeting epidermal growth factor receptor tyrosine kinase, which shows non-inferior efficacy and better safety comparing to gefitinib in previous phase III trial. The present study was designed to further evaluate the efficacy and safety of icotinib in patients with advanced non-small-cell lung cancer (NSCLC) previously treated with platinum-based chemotherapy. Methods Patients with NSCLC progressing after one or two lines of chemotherapy were enrolled to receive oral icotinib (125mg tablet, three times per day). The primary endpoint was progression-free survival. The secondary endpoints included overall survival, objective response rate, time to progression, quality of life and safety. Results From March 16, 2010 to October 9, 2011, 128 patients from 15 centers nationwide were enrolled, in which 124 patients were available for efficacy evaluation and 127 patients were evaluable for safety. The median progression-free survival and time to progression were 5.0 months (95%CI 2.9–6.6 m) and 5.4 months (95%CI 3.1–7.9 m), respectively. The objective response rate and disease control rate were 25.8% and 67.7% respectively. Median overall survival exceeded 17.6 months (95%CI 14.2 m-NA) according to censored data. Further follow-up of overall survival is ongoing. The most frequent treatment-related adverse events were rash (26%, 33/127), diarrhea (12.6%, 16/127) and elevation of transaminase (15.7%, 20/127). Conclusions In general, this study showed similar efficacy and numerically better safety when compared with that in ICOGEN trial, further confirming the efficacy and safety of icotinib in treating patients with advanced NSCLC previously treated with chemotherapy.

    The activity of glufosfamide (beta-D-glucosylisophosphoramide mustard) was tested in a multicentre phase II clinical trial in patients with advanced non-small cell lung cancer (NSCLC) who had received one prior line of platinum-based chemotherapy. Patients were treated with 5000 mg/m(2) glufosfamide by a 1-h intravenous (i.v.) infusion every 3 weeks following registration at the European Organisation for Research and Treatment of Cancer (EORTC) Data Center. Patients were randomised between hydration and no hydration to evaluate the nephroprotective effects of forced diuresis. Patients experiencing >/= 35 micromol/l increase of serum creatinine compared with baseline values were taken off the treatment. The Response evaluation criteria in solid tumours (RECIST) criteria were applied for the response assessment. Blood sampling was performed for a pharmacokinetic analysis. 39 patients from seven institutions were registered and a median of three cycles was given (range 0-6) cycles; 20 patients were randomised to the hydration arm. Haematological toxicity was mild, but treatment-related metabolic and electrolytic abnormalities and increases of serum creatinine occurred in several patients. Hydration did not have any significant influence on the plasma pharmacokinetics of glufosfamide and did not show any nephroprotective effect. Only one confirmed partial remission was observed (response rate 3%; 95% (Confidence Interval (CI) 0-14) and 18 cases with stable disease (49%) were recorded as assessed by an independent panel. Median survival of all patients treated was 5.8 months (95% CI 4.2-7.9). In conclusion, glufosfamide administered by a 1-h infusion every 3 weeks has modest activity in advanced NSCLC patients after one prior platinum-based chemotherapy.

    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

    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.

    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.

    Full Text Available BACKGROUND: In evaluation of the clinical benefit of a new targeted agent in a phase 3 trial enrolling molecularly selected patients with advanced non-small cell lung cancer (NSCLC, overall survival (OS as an endpoint seems to be of limited use because of a high level of treatment crossover for ethical reasons. A more efficient and useful indicator for assessing efficacy is needed. METHODS AND FINDINGS: We identified 18 phase 3 trials in the literature investigating EGFR-tyrosine kinase inhibitor (TKIs or ALK-TKIs, now approved for use to treat NSCLC, compared with standard cytotoxic chemotherapy (eight trials were performed in molecularly selected patients and ten using an "all-comer" design. Receiver operating characteristic analysis was used to identify the best threshold by which to divide the groups. Although trials enrolling molecularly selected patients and all-comer trials had similar OS-hazard ratios (OS-HRs (0.99 vs. 1.04, the former exhibited greater progression-free survival-hazard ratios (PFS-HR (mean, 0.40 vs. 1.01; P<0.01. A PFS-HR of 0.60 successfully distinguished between the two types of trials (sensitivity 100%, specificity 100%. The odds ratio for overall response was higher in trials with molecularly selected patients than in all-comer trials (mean: 6.10 vs. 1.64; P<0.01. An odds ratio of 3.40 for response afforded a sensitivity of 88% and a specificity of 90%. CONCLUSION: The notably enhanced PFS benefit was quite specific to trials with molecularly selected patients. A PFS-HR cutoff of ∼0.6 may help detect clinical benefit of molecular targeted agents in which OS is of limited use, although desired threshold might differ in an individual trial.

    2015-01-01

    Since the development of molecular biology,the treatment of advanced non-small cell cancer is shifting from traditional chemotherapy into molecular targeted therapy with genotyping as a guide′s help.The most widely used is epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs).With the appli-cation of EGFR-TKIs,the resistances to EGFR inhibitors are paid more and more attention,in recent years. The main mechanisms of acquired resistances are as follows:secondary mutation of the EGFR gene,amplifica-tion of c-MET,Her2 and other target genes,histological transformation,activation of the bypass mechanisms, loss of p53,the relief of negative feedback loops,overlap of mechanisms,etc.%随着分子生物学的发展,晚期非小细胞肺癌的治疗由传统的化疗转向以基因分型为指导的分子靶向治疗。其中应用较多的是表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI)类药物。然而EGFR-TKI 的耐药问题近年来受到越来越多的关注,其机制主要有 EGFR 基因二次突变,c-MET、人类表皮生长因子受体2(Her2)等靶基因的扩增,组织表型的改变,旁路途径的激活,p53基因的缺失,细胞信号通路负反馈的减弱以及多重机制叠加等。

    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

    Purpose Although intensity-modulated radiation therapy (IMRT) is increasingly used to treat locally advanced non-small-cell lung cancer (NSCLC), IMRT and three-dimensional conformal external beam radiation therapy (3D-CRT) have not been compared prospectively. This study compares 3D-CRT and IMRT outcomes for locally advanced NSCLC in a large prospective clinical trial. Patients and Methods A secondary analysis was performed to compare IMRT with 3D-CRT in NRG Oncology clinical trial RTOG 0617, in which patients received concurrent chemotherapy of carboplatin and paclitaxel with or without cetuximab, and 60- versus 74-Gy radiation doses. Comparisons included 2-year overall survival (OS), progression-free survival, local failure, distant metastasis, and selected Common Terminology Criteria for Adverse Events (version 3) ≥ grade 3 toxicities. Results The median follow-up was 21.3 months. Of 482 patients, 53% were treated with 3D-CRT and 47% with IMRT. The IMRT group had larger planning treatment volumes (median, 427 v 486 mL; P = .005); a larger planning treatment volume/volume of lung ratio (median, 0.13 v 0.15; P = .013); and more stage IIIB disease (30.3% v 38.6%, P = .056). Two-year OS, progression-free survival, local failure, and distant metastasis-free survival were not different between IMRT and 3D-CRT. IMRT was associated with less ≥ grade 3 pneumonitis (7.9% v 3.5%, P = .039) and a reduced risk in adjusted analyses (odds ratio, 0.41; 95% CI, 0.171 to 0.986; P = .046). IMRT also produced lower heart doses ( P < .05), and the volume of heart receiving 40 Gy (V40) was significantly associated with OS on adjusted analysis ( P < .05). The lung V5 was not associated with any ≥ grade 3 toxicity, whereas the lung V20 was associated with increased ≥ grade 3 pneumonitis risk on multivariable analysis ( P = .026). Conclusion IMRT was associated with lower rates of severe pneumonitis and cardiac doses in NRG Oncology clinical trial RTOG 0617, which supports

    Objective To investigate the efficacy of pemetrexed as a second line treatment for advanced-stage non-small cell lung cancer (NSCLC), which was failed to the standard platium-based chemotherapies. Methods Fifty qualifed patients received pemetrexed 500 mg/m~2, for 2 cycles with every 21 days each. Quality of life(QOL) was assessed with QLQ-30 and QLQ-LC13 forms. Disease control was assessed by response evaluation criteria in solid tumors(RECIST). Results Of 50 cases, 22 cases had partial remission (PR) , 20 cases had stable disease (SD) , and 8 cases had progressive disease (PD). Except the social function in the 5-function scales, all other 4 functions and the mean scores of QOL were improved significantly after pemetrexed therapy (P<0. 05). Mean scores of major general symptoms, like hypodynamia and anorexia, and disease-related symptoms were decreased significantly (P<0. 05). Conclusion As a second line treatment, premetrexed not only increases the survival, but also reduces tumor-related symptoms and improves QOL in the advanced-stage NSCLC patients, who have received platium-based regiments previously.%目的 探讨培美曲塞二线治疗晚期非小细胞肺癌(NSCLC)的临床疗效.方法 一线含铂方案化疗后复发的晚期NSCLC患者50例,使用培美曲塞(500 mg/m~2,d_1)治疗2个周期(21 d×2).治疗前后分别采用QLQ-C30和QLQ-LC13问卷,对患者的生活质量和症状进行评价,按RECIST标准评判临床疗效.结果 部分缓解(PR)6例,稳定(SD)26例,进展(PD)18例.与治疗前比较,除社会功能外,体格、角色、情感、认知4种功能状态和整体生活质量评分均显著提高(P<0.05);乏力、食欲不振2个全身症状及5种疾病相关症状评分显著降低(P<0.05).结论 培美曲塞二线治疗晚期NSLC能显著改善肺癌相关症状,提高患者生活质量.

    The previous AVAPERL trial demonstrated that induction therapy with first-line cisplatin (CDDP), pemetrexed (PEM) and bevacizumab (BEV), followed by continuation maintenance therapy with PEM+BEV, improved the progression-free survival (PFS) and overall survival (OS) compared with BEV alone (median PFS, 10.2 vs. 6.6 months and median OS, 19.8 vs. 15.9 months, respectively) in patients with advanced non-squamous non-small-cell lung cancer (non-Sq NSCLC). However, those findings were based on selected patients who were eligible for BEV and maintenance therapy. To assess the efficacy of CDDP+PEM as first-line therapy in selected patients depending on their eligibility for BEV and maintenance therapy, consecutive patients with non-Sq NSCLC who received first-line chemotherapy with CDDP+PEM at the Shizuoka Cancer Center (Shizuoka, Japan) between July, 2009 and December, 2013 were retrospectively reviewed. A total of 160 patients were assessed, including 92 who were eligible and 68 who were not eligible for BEV treatment. In the BEV-eligible group, CDDP+PEM treatment followed by maintenance PEM exhibited significantly superior efficacy compared with that in the BEV-ineligible group (median PFS, 5.8 vs. 4.8 months, respectively, P=0.013; and median OS, 21.3 vs. 12.6 months, respectively, P=0.0025). In the BEV-eligible group, 60 patients were suitable for maintenance therapy with PEM (group A) and 32 patients were unsuitable (group B). In the BEV-ineligible group, 31 patients were suitable for maintenance therapy with PEM (group C) and 37 patients were unsuitable (group D). In group A, the median PFS and OS were 6.9 and 31.8 months, respectively, compared with 2.4 and 10.5 months in group B, 6.1 and 18.5 months in group C, and 2.8 and 7.7 months in group D. The PFS and OS in group A were significantly better compared with those in the other groups. Thus, the PFS and OS with CDDP+PEM were favorable among patients with advanced non-Sq NSCLC who were eligible for BEV and

    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.

    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. Median progression-free survival (PFS was 4.6 months for arm A vs. 3.5 months for arm B (HR = 1.03; 95% CI, 0.45–2.27; p = 0.95 and median overall survival (OS was 15.0 months for arm A vs. 14.8 months for arm B (HR = 0.79; 95% CI, 0.40–1.51; p = 0.60, showing no difference between the two arms. The response rate, disease control rate, and the transit rate to maintenance phase were 36.0% (9/25, 64.0% (16/25, and 48% (12/25 for arm A vs. 16.7% (4/24, 50.0% (12/24, and 33% (8/24 for arm B, which were also statistically similar between the two arms (p = 0.13, p = 0.32, and p = 0.30, respectively.

    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

    Full Text Available Abstract Background The aim of the study was to determine the maximal tolerated dose (MTD of gemcitabine every two weeks concurrent to radiotherapy, administered during an aggressive program of sequential and simultaneous radiochemotherapy for locally advanced, unresectable non-small cell lung cancer (NSCLC and to evaluate the efficacy of this regime in a phase II study. 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. These patients showed persisting dysphagia 3 to 4 weeks after completing radiotherapy. In accordance with expected complications as esophagitis, dysphagia and odynophagia, we defined the MTD at this dose level, although no dose limiting toxicity (DLT grade 3 was reached. In the phase I/II median follow-up was 15.7 months (4.1 to 42.6 months. The overall response rate after completion of therapy was 64%. The median overall survival was 19.9 (95% CI: [10.1; 29.7] months for all eligible patients. The median disease-free survival for all patients was 8.7 (95% CI: [2.7; 14.6] months. Conclusion

    Full Text Available Background and objective Although the guidelines of the National Comprehensive Cancer Network of USA recommend that the standard therapy for locally advanced non-small cell lung cancer (LANSCLC is concurrent chemoradiotherapy. There is ongoing controversy about the treatment regimen which combines chemotherapy concurrently with radiotherapy. The aim of this study is to compare weekly usage with triple weekly usage of paclitaxel in concurrent radiochemotherapy for patients with LANSCLC, and to obtain the best paclitaxel regimen in the concurrent radiochemotherapy. Methods From April 2006 to April 2009, some LANSCLC patients in multicenter were randomly divided into weekly usage (45 mg/m2, 1 times/week, a total of 270 mg/m2 in six weeks and triple weekly usage (15 mg/m2, 3 times/week, a total of 270 mg/m2 in six weeks group of paclitaxel by a random number table. All patients were treated with 3D radiotherapy, and 95% planning target volume (PTV received a prescription dose of (60-70 Gy/(30-35times/(6-7weeks, (1.8-2.0 Gy/fraction.

    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.

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.

    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.

    Full Text Available Background/Aims: Previous studies have shown that patients with schizophrenia have a lower incidence of cancer than the general population, and several antipsychotics have been demonstrated to have cytotoxic effects on cancer cells. However, the mechanisms underlying these results remain unclear. The present study aimed to investigate the effect of clozapine, which is often used to treat patients with refractory schizophrenia, on the growth of non-small cell lung carcinoma cell lines and to examine whether autophagy contributes to its effects. Methods: A549 and H1299 cells were treated with clozapine, and cell cytotoxicity, cell cycle and autophagy were then assessed. The autophagy inhibitor bafilomycin A1 and siRNA-targeted Atg7 were used to determine the role of autophagy in the effect of clozapine. Results: Clozapine inhibited A549 and H1299 proliferation and increased p21 and p27 expression levels, leading to cell cycle arrest. Clozapine also induced a high level of autophagy, but not apoptosis, in both cell lines, and the growth inhibitory effect of clozapine was blunted by treatment with the autophagy inhibitor bafilomycin A1 or with an siRNA targeting atg7. Conclusions: Clozapine inhibits cell proliferation by inducing autophagic cell death in two non-small cell lung carcinoma cell lines. These findings may provide insights into the relationship between clozapine use and the lower incidence of lung cancer among patients with schizophrenia.

    Interobserver variability in the definition of target volumes (TVs) is a well-known confounding factor in (multicentre) clinical studies employing radiotherapy. Therefore, detailed contouring guidelines are provided in the prospective randomised multicentre PET-Plan (NCT00697333) clinical trial protocol. This trial compares strictly FDG-PET-based TV delineation with conventional TV delineation in patients with locally advanced non-small cell lung cancer (NSCLC). Despite detailed contouring guidelines, their interpretation by different radiation oncologists can vary considerably, leading to undesirable discrepancies in TV delineation. Considering this, as part of the PET-Plan study quality assurance (QA), a contouring dummy run (DR) consisting of two phases was performed to analyse the interobserver variability before and after teaching. In the first phase of the DR (DR1), radiation oncologists from 14 study centres were asked to delineate TVs as defined by the study protocol (gross TV, GTV; and two clinical TVs, CTV-A and CTV-B) in a test patient. A teaching session was held at a study group meeting, including a discussion of the results focussing on discordances in comparison to the per-protocol solution. Subsequently, the second phase of the DR (DR2) was performed in order to evaluate the impact of teaching. Teaching after DR1 resulted in a reduction of absolute TVs in DR2, as well as in better concordance of TVs. The Overall Kappa(κ) indices increased from 0.63 to 0.71 (GTV), 0.60 to 0.65 (CTV-A) and from 0.59 to 0.63 (CTV-B), demonstrating improvements in overall interobserver agreement. Contouring DRs and study group meetings as part of QA in multicentre clinical trials help to identify misinterpretations of per-protocol TV delineation. Teaching the correct interpretation of protocol contouring guidelines leads to a reduction in interobserver variability and to more consistent contouring, which should consequently improve the validity of the overall study

    BACKGROUND: Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) targeted treatment has been a standard therapy for advanced non-small cell lung cancer (NSCLC), but it is not tolerated well by all patients. In China, some studies have reported that traditional Chinese medicinal herbs (TCMHs) may increase efifcacy and reduce toxicity when combined with EGFR-TKI, but outside of China few studies of this kind have been attempted. OBJECTIVE:This study is intended to systematically review the existing clinical evidence on TCMHs combined with EGFR-TKI for treatment of advanced NSCLC. SEARCH STRATEGY:PubMed, the Cochrane Library, the Excerpta Medica Database (EMBASE), the China BioMedical Literature (CBM), and the China National Knowledge Infrastructure (CNKI) and web site of the American Society of Clinical Oncology (ASCO), the European Society for Medical Oncology (ESMO), the World Conference of Lung Cancer (WCLC) were searched; the search included all documents published in English or Chinese before October 2013. INCLUSION CRITERIA:We selected randomized controlled trials based on speciifc criteria, the most important of which was that a TCMH plus EGFR-TKI treatment group was compared with an EGFR-TKI control group in patients with advanced NSCLC. DATA EXTRACTION AND ANALYSIS: The modiifed Jadad scale was used to assess the quality of studies. For each included study, patient characteristics, treatment details, therapeutic approach and clinical outcomes were collected on a standardized form. When disagreements on study inclusion or data extracted from a study emerged, the consensus of all coauthors provided the resolution. The clinical outcome metrics consisted of objective response rate (ORR; complete response + partial response divided by the total number of patients), disease control rate (DCR; complete response + partial response + no change divided by the total number of patients), survival rate, improved or stabilized Karnofsky performance status

    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。

    Non-small-cell lung cancer (NSCLC) constitutes 85% of all lung cancers, and is the leading cause of cancer-related death worldwide. The poor prognosis and resistance to both radiation and chemotherapy warrant further investigation into the molecular mechanisms of NSCLC and the development of new, more efficacious therapeutics. The processes of autophagy and apoptosis, which induce degradation of proteins and organelles or cell death upon cellular stress, are crucial in the pathophysiology of NSCLC. The close interplay between autophagy and apoptosis through shared signaling pathways complicates our understanding of how NSCLC pathophysiology is regulated. The apoptotic effect of autophagy is controversial as both inhibitory and stimulatory effects have been reported in NSCLC. In addition, crosstalk of proteins regulating both autophagy and apoptosis exists. Here, we review the recent advances of the relationship between autophagy and apoptosis in NSCLC, aiming to provide few insights into the discovery of novel pathogenic factors and the development of new cancer therapeutics.

    The aim of the present study was to determine whether kaempferol has a radiosensitization potential for lung cancer in vitro and in vivo. The in vitro radio-sensitization activity of kaempferol was elucidated in A-549 lung cancer cells by using an MTT (3-(4 5-dimethylthiazol-2-yl)-25-diphenyl-tetrazolium bromide) assay, cell cycle analysis and clonogenic assay. The in vivo activity was evaluated in the BALB/c nude mouse xenograft model of A-549 cells by hematoxylin and eosin staining and immunohistochemistry, and the tumor volume was recorded. Protein levels of the apoptotic pathway were detected by western blot analysis. Treatment with kaempferol inhibited the growth of A-549 cells through activation of apoptotic pathway. However, the same doses did not affect HFL1 normal lung cell growth. Kaempferol induced G2/M cell cycle arrest and the enhancement of radiation-induced death and clonogenic survival inhibition. The in vivo data showed that kaempferol increased tumor cell apoptosis and killing of radiation. In conclusion, the findings demonstrated that kaempferol increased tumor cell killing by radiation in vitro and in vivo through inhibition of the AKT/PI3K and ERK pathways and activation of the mitochondria apoptosis pathway. The results of the present study provided solid evidence that kaempferol is a safe and potential radiosensitizer.

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.

Methods:The clinical data of 289 advanced NSCLC patients hospitalized from April 2009 to October 2013 were retrospectively analyzed. All the enrolled patients were newly diag-nosed NSCLC with stage Ⅳ and not received treatment previously. Of those patients,223 had no brain metastasis. The rest were diagnosed with brain metastasis. Results:The incidence of brain metastasis was 22. 8%(66 / 289),the medi-an survival time of patients with the brain metastasis was 9. 4 months. The 1 - year and 2 - year survival rates were 37% and 15% respectively. The serum level of carcinoembryonic antigen(CEA)was significantly different between no brain metastasis patients and those who had(P = 0. 001). The median value of CEA of patients with and without brain metastasis was 6. 8ng/ ml,16. 0ng/ ml respectively. Overall survival was significantly shorter among patients with elevated serum CEA(median survival 15 months vs. 8 months,P = 0. 027)or CA125(median survival 13 months vs. 7 months,P = 0. 008). In multivariate analysis,CA125,radiotherapy and sex were independent prognostic factors for brain metastasis(P < 0. 05). Conclusion:The high serum CEA level may be potentially used as an indicator to predict the probability of brain metastasis in patients with NSCLC. The high serum CA125 may be used as reference index of the prognosis of brain metastasis in patients with NSCLC.%目的:探讨血清 CEA、CA125、CA153、CA199、CA724和 CYFRA21-1水平与晚期非小细胞肺癌(NSCLC)脑转移发生和预后的相关性。方法:回顾性分析我院2009年4月至2013年10月289例(非脑转移223例,脑转移66例)未进行过任何治疗的Ⅳ期 NSCLC 患者临床资料。结果:全组病例脑转移发生率为22.8%(66/289),66例脑转移的中位生存期为9.4个月,1年、2年生存率分别为37%、15

    2017-01-01

    Afatinib, a second-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, has been approved worldwide as a first-line treatment for advanced non-small cell lung cancer (NSCLC) that harbors activating EGFR mutations. Here, we have reviewed the recent clinical developments in the treatment of lung cancer using afatinib. Emerging data have revealed the overall survival benefit of first-line afatinib therapy in patients with advanced EGFR (del19)-positive NSCLC. Phase III studies of afatinib have shown the effectiveness of afatinib as a second-line treatment for advanced lung squamous cell carcinoma, as well as the benefit of continuing afatinib therapy in combination with cytotoxic chemotherapy for advanced NSCLC after the occurrence of disease progression in patients who are receiving afatinib monotherapy. Therapeutic benefits of afatinib have also been reported in studies of patients with central nervous system metastasis and patients with HER2 mutation. The utility of afatinib-based combination therapies is being investigated in ongoing research.

    Lung cancer remains the most frequently diagnosed cancer in the United States, excluding non-melanoma skin cancer. Non-small cell lung cancer (NSCLC) constitutes the majority (more than 80%) of lung cancer diagnoses. Systemic therapy, with either cytotoxic chemotherapy and/or targeted therapies, has been established to provide benefit to patients with NSCLC in both the adjuvant and advanced disease settings. Vinorelbine, a semi-synthetic vinca-alkaloid has been extensively tested alone and in combination with other cytotoxic or targeted agents in the treatment of NSCLC. Its safety has been well established with neutropenia, anemia, nausea, and vomiting being the most frequently encountered toxicities. The data defining the risks and benefits of vinorelbine in the treatment of NSCLC will be summarized. PMID:21695100

    In the last 5 years, the current management of stage I non-small-cell lung cancer has been challenged due to novel surgical approaches and advances in radiation technology. The outcome after a sublobar resection is promising, especially for tumors less than 2 cm. Other treatment opportunities are available for high risk patients with comorbidity and impaired pulmonary function. Stereotactic ablative body radiotherapy is a good alternative treatment to surgery, especially in elderly and comorbid patients. However, randomized evidence comparing sublobar resection and stereotactic radiotherapy is presently lacking. The most recent development in radiotherapy is hadron therapy with a presumed reduced toxicity because of its peculiar physical and biological effects. Promising thermal and microwave ablative techniques are in development and have specific niche indications.

    Recently, several studies have been carried about maintenance therapy in non-small cell lung cancer, and some chemotherapy agents have been approved for clinical practice. But there are still a lot of questions about maintenance therapy that we have to consider. For example, the defects of design in maintenance therapy trials;how to choose gold standard of maintenance therapy for evaluation;who beneift from the maintenance therapy and how to estimate pharmaceutical eco-nomics. In this paper, we will make deep analysis about these issues.%近年来,针对晚期非小细胞肺癌的维持治疗进行了诸多临床研究,而这些研究亦已使得部分药物通过审批应用于临床实践。但是目前维持治疗仍存在诸多不容忽视的问题和质疑,如维持治疗试验设计中存在的缺陷和疏漏;维持治疗评价金标准是什么;获益人群以及维持治疗的药效经济学等问题,本文就上述问题作进一步解析。

The aim of this review is to analyze trials of targeted therapies in localized NSCLC. In patients with wild-type EGFR, tyrosine kinase inhibitors have shown no efficacy in Phase III trials. Few data are available for EGFR-mutated localized NSCLC, as routine biological profiling is not recommended. Available studies are small, often retrospectives, and/or conducted in a single-center making it difficult to draw firm conclusions. Ongoing prospective Phase III trials are comparing adjuvant tyrosine kinase inhibitor administration versus adjuvant chemotherapy. By analogy with the indication of bevacizumab in advanced NSCLC, use of antiangiogenic agents in the perioperative setting is currently restricted to nonsquamous NSCLC. Several trials of adjuvant or neoadjuvant bevacizumab are planned or ongoing, but for the moment there is no evidence of efficacy. Data on perioperative use of biomarkers in early-stage NSCLC come mainly from small, retrospective, uncontrolled studies. Assessment of customized adjuvant or neoadjuvant therapy in localized NSCLC (with or without oncogenic driver mutations is a major challenge.

    Liquid biopsy analyses are already incorporated in the routine clinical practice in many hospitals and oncology departments worldwide, improving the selection of treatments and monitoring of lung cancer patients. Although they have not yet reached its full potential, liquid biopsy-based tests will soon be as widespread as “standard” biopsies and imaging techniques, offering invaluable diagnostic, prognostic, and predictive information. This review summarizes the techniques available for the isolation and analysis of circulating free DNA and RNA, exosomes, tumor-educated platelets, and circulating tumor cells from the blood of cancer patients, presents the methodological challenges associated with each of these materials, and discusses the clinical applications of liquid biopsy testing in lung cancer.

    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.

    Metastin, the product of the KISS-1 gene, seems to represent a strong suppressant of metastasis for some types of cancer. The aim of this study is to explore whether circulating levels of metastin could be used as a marker for the metastatic potential of non-small cell lung cancer (NSCLC) as well as a diagnostic marker in NSCLC patients. The possible correlation between metastin and leptin circulating levels was also evaluated. Fasting serum levels of metastin and leptin were determined in 96 NSCLC patients at diagnosis (76 with metastatic disease and 21 with locally advanced disease) and 49 healthy volunteers using commercial available ELISA. Serum metastin levels presented no differences between NSCLC patients and healthy volunteers (1.18 ± 0.98 vs. 1.17 ± 0.39 ng/ml, P = 0.979) as well as between patients with metastatic and locally advanced disease (1.17 ± 1.05 vs. 1.21 ± 0.64 ng/ml, P = 0.872). There was no statistically significant correlation between circulating metastin and leptin levels in NSCLC patients and patients with locally advanced and metastatic disease. This study shows a lack of direct involvement of metastin in the diagnosis and metastatic potential of NSCLC.

    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 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

    (1) Platinum-based chemotherapy is generally used to treat advanced-stage non small-cell lung cancer (stages III and IV), but has only a modest impact on survival. There is no reference treatment. (2) Gefitinib inhibits the tyrosine kinase activity of the receptor for EGF (epidermal growth factor), which is thought to be involved in tumour growth. It has a temporary licence in France and is used on a named-patient basis, but full marketing authorisation has already been granted in Japan, the United States, and elsewhere. (3) Two double-blind dose-finding studies compared two doses of oral gefitinib monotherapy (250 mg/day and 500 mg/day) in patients in whom at least two lines of chemotherapy had failed. The results were favourable, with a median survival of 6 months and a symptomatic improvement in some patients, but they are undermined by the absence of a placebo group and by major protocol violations. (4) Two double-blind trials, each in more than 1000 patients, showed that gefitinib does not increase the efficacy of first-line platinum combinations. (5) About 15% of patients receiving gefitinib monotherapy in clinical trials stopped taking the treatment because of adverse events. The most frequent were gastrointestinal (diarrhea, nausea, vomiting) and cutaneous (rash, acne, dry skin, pruritus). (6) Interstitial pneumonitis occurred in about 1% of patients, and was fatal in about one-third of cases. (7) Gefitinib is metabolised by the cytochrome P450 isoenzyme CYP3A4, so carries a potentially high risk of interactions. (8) In practice, more thorough assessment of gefitinib is needed to determine whether this new drug is beneficial for patients with non small-cell lung cancer. Marketing authorisation is not currently justified.

    The therapeutic cancer vaccines have low toxicity and well tolerance. However, many clinical studies of vaccines for NSCLC have not made significant progress. The major difficulties in the development of therapeutic cancer vaccines include the lack of tumor specific antigen, the tumor escape mechanisms from host immune surveillance and immune tolerance. In recent years, new insights in the interaction between tumors and the immune system, the better identification of antigenic targets, the addition of immunoadjuvants and the production of more efficient delivery systems have resulted in more sophisticated vaccines, such as antigen-specific vaccines targeting melanoma-associated antigen-A3 , mucin 1 and EGF, and whole-cell vaccines such as belagenpumatucel-L. These vaccines have shown promising results in phase II clinical trials, and need to be evaluated in Phase II clinical trials.%非小细胞肺癌(non-small cell lung cancer,NSCLC)的疫苗治疗具有不良反应小、耐受性好的特点,但众多的临床研究并未取得突破性的进展.影响疫苗治疗肺癌的主要困难包括由于肿瘤免疫原性弱而缺乏肿瘤特异性抗原以及宿主免疫监视下的肿瘤免疫逃逸和免疫耐受.近几年来,随着人们对肿瘤和免疫系统关系的进一步认识,特异性肿瘤抗原的发现及免疫佐剂和载体的发展,疫苗治疗NSCLC已经取得了显著的进展,如melanoma-associated antigen-A3疫苗、针对mucin 1抗原的疫苗、EGF疫苗等抗原特异性疫苗以及将TGF-β2转染NSCLC细胞株制成的全细胞疫苗Belagenpumatucel-L等.多个Ⅱ期临床研究已经证实了它们在NSCLC中的疗效,相应多中心的Ⅲ期临床研究正在进行中.

    Full Text Available Despite significant advances in the detection and treatment of lung cancer, it causes the highest number of cancer-related mortality. Recent advances in the detection of genetic alterations in patient samples along with physiologically relevant animal models has yielded a new understanding of the molecular etiology of lung cancer. This has facilitated the development of potent and specific targeted therapies, based on the genetic and biochemical alterations present in the tumor, especially non-small-cell lung cancer (NSCLC. It is now clear that heterogeneous cell signaling pathways are disrupted to promote NSCLC, including mutations in critical growth regulatory proteins (K-Ras, EGFR, B-RAF, MEK-1, HER2, MET, EML-4-ALK, KIF5B-RET, and NKX2.1 and inactivation of growth inhibitory pathways (TP53, PTEN, p16, and LKB-1. How these pathways differ between smokers and non-smokers is also important for clinical treatment strategies and development of targeted therapies. This paper describes these molecular targets in NSCLC, and describes the biological significance of each mutation and their potential to act as a therapeutic target.

    Full Text Available MiR-122 is a novel tumor suppresser and its expression induces cell cycle arrest, or apoptosis, and inhibits cell proliferation in multiple cancer cells, including non-small cell lung cancer (NSCLC cells. Radioresistance of cancer cell leads to the major drawback of radiotherapy for NSCLC and the induction of radiosensitization could be a useful strategy to fix this problem. The present work investigates the function of miR-122 in inducing radiosensitization in A549 cell, a type of NSCLC cells. MiR-122 induces the radiosensitization of A549 cells. MiR-122 also boosts the inhibitory activity of ionizing radiation (IR on cancer cell anchor-independent growth and invasion. Moreover, miR-122 reduced the expression of its targeted genes related to tumor-survival or cellular stress response. These results indicate that miR-122 would be a novel strategy for NSCLC radiation-therapy.

    Emerging evidence on the role of the antitumor activity of the immune system has generated great interest in immunotherapy even for tumors that were historically considered as nonimmunogenic. Immunotherapy is emerging as a major modality in non-small cell lung cancer (NSCLC) treatment focusing on vaccine approaches to elicit specific immune responses and development of inhibitors of the molecular mediators of cancer-induced immunosuppression (immune checkpoints) to boost antitumor immune responses. Amplification of the host response against evolving tumors through vaccination is being investigated in ongoing clinical trials with tumor cell vaccines; however, the clinical efficacy of these agents has been limited. Blocking inhibitory pathways such as the CTL antigen 4 (CTLA-4) and programmed cell death 1 (PD-1) checkpoint pathways with mAbs has generated antitumor immune responses that are transforming cancer therapeutics. PD-1 and programmed cell death ligand 1 (PD-L1) antibodies have shown durable responses in NSCLC, with a favorable safety profile and manageable side effects. The activity of immune checkpoint inhibitors is currently been assessed in treatment-naïve patients with PD-L1-positive advanced NSCLC. Combinatorial approaches with other immune checkpoint inhibitors, chemotherapy, or targeted agents are being explored in ongoing clinical trials, and may improve outcome in NSCLC.

    Stathmin 1 (STMN1), a major microtubule-depolymerizing protein, is involved in cell cycle progression and cell motility. However, the clinical significance of STMN1 expression in non-small cell lung cancer (NSCLC) has not been determined. The expression pattern of STMN1 mRNA was analyzed by quantitative real-time PCR (qRT-PCR) in 37 cases of NSCLC and in the corresponding non-tumor tissue samples. Furthermore, immunohistochemistry was performed to detect STMN1 protein expression in 113 primary NSCLC tissues. The functional role of STMN1 in lung cancer cell lines was evaluated by small interfering RNA-mediated depletion followed by analyses of cell proliferation and invasion. We found that the STMN1 mRNA and protein levels in NSCLC tissues were significantly higher than those in the corresponding non-tumor tissues (P<0.001). In addition, increased STMN1 expression was correlated with poor tumor differentiation (P<0.001), large tumor size (P=0.022), advanced N stage (P=0.033), and advanced TNM stage (P<0.001). Kaplan-Meier analysis indicates that NSCLC patients with higher STMN1 expression showed significantly worse survival. Moreover, multivariate analysis indicates that higher STMN1 protein expression was an independent prognostic factor of disease-specific survival (HR 2.247, 95%CI 1.320-3.825, P=0.003). Finally, the knockdown of STMN1 in lung cancer cells resulted in a decrease in cellular proliferation and invasion. Our findings suggest that STMN1 may have an important role in NSCLC progression and could serve as a potential prognostic marker for 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.

    Targeted therapies are revolutionizing the treatment of advanced non-small cell lung cancer (NSCLC). The discovery of key oncogenic events mainly in lung adenocarcinoma, like EGFR mutations or ALK rearrangements, has changed the treatment landscape while improving the prognosis of lung cancer patients. Inevitably, virtually all patients initially treated with targeted therapies develop resistance because of the emergence of an insensitive cellular population, selected by pharmacologic pressure. Diverse mechanisms of resistance, in particular to EGFR, ALK and ROS1 tyrosine-kinase inhibitors (TKIs), have now been discovered and may be classified in three different groups: (1) alterations in the target (such as EGFR T790M and ALK or ROS1 mutations); (2) activation of alternative pathways (i.e. MET amplification, KRAS mutations); (3) phenotype transformation (to small cell lung cancer, epithelial-mesenchymal transition). These basic mechanisms are informing the development of novel therapeutic strategies to overcome resistance in the clinic. Novel-generation molecules include osimertinib, for EGFR-T790M-positive patients, and new ALK-TKIs. Nevertheless, the possible concomitant presence of multiple resistance mechanisms, as well as their heterogeneity among cells and disease localizations, makes research in this field particularly arduous. In this chapter, available evidence and perspectives concerning precise mechanisms of escape to pharmacological inhibition in oncogene-addicted NSCLC are reported for single targets, including but not limited to EGFR and ALK.

    Non-small cell lung cancer (NSCLC) represents close to 90% of all lung cancers. When diagnosed, most cases are on an advanced and inoperable stage, with limited therapeutic options. Existing therapies have shown to be insufficient and novel strategies are urgently necessary. New advances in understanding the disease at cellular and molecular level however have helped researchers in devising novel strategies for therapy. These directed therapies limit cancer growth by targeting specific molecules related with tumor progression. Such strategies have shown to be more effective than chemotherapy and radiotherapy and can be complemented to existing therapeutic paradigm in augmenting beneficial outcome. Lung cancer could benefit from such innovative therapy. RNA interference (RNAi) is a sequence-specific gene silencing mechanism and, since its discovery widespread applications have pointed it as a powerful tool in cancer treatment. Several on-going clinical trials have been successfully demonstrating its potential as a novel therapeutic, including in the treatment of NSCLC. Here, we revise the recent findings concerning the therapeutic effects of molecular variations associated with NSCLC and where targeted therapies stand in its treatment, with special focus on RNAi-mediated gene silencing as a powerful strategy for NSCLC treatment.

    Full Text Available The landscape of advanced non-small lung cancer (NSCLC therapies has rapidly been evolving beyond chemotherapy over the last few years. The discovery of oncogenic driver mutations has led to new ways in classifying NSCLC as well as offered novel therapeutic targets for anticancer therapy. Targets such as epidermal growth factor receptor (EGFR mutations and anaplastic lymphoma kinase (ALK gene rearrangements have successfully been targeted with appropriate tyrosine kinase inhibitors (TKIs. Other driver mutations such as ROS, MET, RET, BRAF have also been investigated with targeted agents with some success in the early phase clinical setting. Novel strategies in the field of immune-oncology have also led to the development of inhibitors of cytotoxic T lymphocyte antigen-4 (CTLA-4 and programmed death-1 receptor (PD-1, which are important pathways in allowing cancer cells to escape detection by the immune system. These inhibitors have been successfully tried in NSCLC and also now bring the exciting possibility of long term responses in advanced NSCLC. In this review recent data on novel targets and therapeutic strategies and their future prospects are discussed.

    Full Text Available Non-small-cell lung cancer (NSCLC is the leading cause of death from cancer for both men en women. Chemotherapy is the mainstay of treatment in advanced disease, but is only marginally effective. In about 30% of patients with advanced NSCLC in East Asia and in 10-15% in Western countries, EGFR mutations are found. In this population, first-line treatment with the tyrosine kinase inhibitors (TKI erlotinib, gefitinib or afatinib is recommended. The treatment beyond progression is less well-defined. In this paper we present 3 patients, EGFR mutation positive, with local progression after an initial treatment with TKI. These patients were treated with local radiotherapy. TKI was temporarily stopped and restarted after radiotherapy. We give an overview of the literature and discuss the different treatment options in case of progression after TKI: TKI continuation with or without chemotherapy, TKI continuation with local therapy, alternative dosing or switch to next-generation TKI or combination therapy. There are different options for treatment beyond progression in EGFR mutation positive metastatic NSCLC, but the optimal strategy is still to be defined. Further research on this topic is ongoing.

    Full Text Available The rate of the anaplastic lymphoma kinase (ALK gene rearrangements in non-small cell lung cancer (NSCLC tissues is 3%-5%. The first-in-class ALK tyrosine kinase inhibitor, crizotinib, can effectively target these tumors represent a significant advance in the evolution of personalized medicine for NSCLC. A randomized phase III clinical trial in which superiority of crizotinib over chemotherapy was seen in previously treated ALK-positive NSCLC patients demonstrated durable responses and well tolerance in the majority of ALK-positive NSCLC patients treated with crizotinib. However, despite the initial responses, most patients develop acquired resistance to crizotinib. Several novel therapeutic approaches targeting ALK-positive NSCLC are currently under evaluation in clinical trials, including second-generation ALK inhibitors, such as LDK378, CH5424802 (RO5424802, and AP26113, and new agents shock protein 90 inhibitors. This review aims to present the current knowledge on this fusion gene, the treatment advances, and novel drug clinical trials in ALK rearranged NSCLC.

    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.

    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

    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.

    2015-06-01

    Full Text Available The present study was done to determine whether kaempferol, a natural polyphenol of the flavonoid family, affects Epithelial-Mesenchymal Transition (EMT in non-small cell lung cancer cells. Kaempferol not only inhibited cancer cell proliferation and migration in a dose-dependent manner but also modulated the expression of EMT-related proteins E-cadherin and vimentin which are indispensible to cellular motility, invasiveness and metastasis. These results indicate that kaempferol suppresses non-small cell lung cancer migration by modulating the expression of EMT proteins. Therefore, kaempferol may be useful as a potential anticancer agent for non-small cell lung cancer.

    The last decade has witnessed rapid advances in the discovery and development of immune checkpoint inhibitors in cancer medicine, particularly drugs targeting programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) in non-small cell lung cancer (NSCLC). The proven antitumor efficacy coupled with low rates of drug-related toxicities observed, albeit idiosyncratic, with these novel immunotherapeutics have led to the registration of multiple PD-1 and PD-L1 inhibitors, such as nivolumab, pembrolizumab, and atezolizumab, in second-line advanced NSCLC, whereas durvalumab and avelumab are in late-phase clinical testing. Moreover, pembrolizumab has shown a survival advantage in the first-line setting; however, nivolumab failed to show a survival benefit possibly relating to patient selection based on PD-L1 expression. Current patient selection is based on PD-L1 expression, using the relevant companion diagnostic test, where patients with strong PD-L1 expression being more likely to respond to these novel agents. Ongoing clinical research focuses on the development of PD-1 and PD-L1 inhibitor monotherapy in neoadjuvant and adjuvant NSCLC. There is also much interest in using these drugs as a therapeutic backbone for rational combinations with other treatment modalities including cytotoxic chemotherapies in the first-line NSCLC, other immunotherapies such as cytotoxic T-lymphocyte-associated protein 4 antagonists, molecularly targeted agents including EGFR and ALK inhibitors, and radiotherapy. Concurrent treatment with radiotherapy is of particular interest owing to the potential for the abscopal effect, using radiotherapy to facilitate systemic treatment.

    Biguanides, used for anti-diabetic drugs, bring more attention in cancer research for their beneficial effects. Phenformin is more potent than metformin. However its potential application as a anti-cancer regent is far behind metformin. In order to investigate any beneficial effect of combination of Phenformin and radiotherapy, non-small cell lung cancer cell lines A549 and H1299 were exposure under different dose of ionizing radiation with or without Phenformin. Results indicated Phenformin showed synergistic effect and could induce more cancer cell apoptosis and inhibition of tumor growth compared with ionizing radiation alone. Furthermore, this synergistic effect may be through different pathway according to cancer cell genotype background. Our results showed Phenformin induced AMPK activation in A549 but not H1299. However, Phenformin activated eIF2α in both cell lines. Our findings implicated Phenformin may be used as radiosensitizer for non-small cell lung cancer therapy.

The proportion of Th17 and Treg cells of the non-remission group after chemotherapy were all significantly higher than before chemotherapy (P < 0. 05),and were higher than those of the control group(P < 0. 05). The proportion of Th17 cells were posi-tively related to the proportion of Treg cells in the peripheral blood of patients with advanced non-small cell lung cancer before and after chemotherapy(r = 0. 589,0. 657;P < 0. 05). Conclusion Chemotherapy can reduce the proportion of Th17 cells and Treg cells in the peripheral blood of patients with advanced non-small cell lung cancer, and has the positive significance for tumor immune function.

    Full Text Available Lung Cancer is the most common cause of cancer related deaths that frequently metastasizes prior to disease diagnosis. Circulating tumor cells (CTCs are found in many different types of epithelial tumors and are of great clinical interest in terms of prognosis and therapy intervention. Here, we present and discuss EpCAM-dependent and -independent capture of CTCs in non-small cell lung cancer (NSCLC and the clinical relevance of CTC detection and characterization. Taking blood samples and analyzing CTCs as liquid biopsy might be a far less invasive diagnostic strategy than biopsies of lung tumors or metastases. Moreover, sequential blood sampling allows to study the dynamic changes of tumor cells during therapy, in particular the development of resistant tumor cell clones.

    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.

    Full Text Available Objectives: Stage III non-small cell lung cancer (NSCLC has a poor prognosis. Reports suggest that five-year survival after current treatment is between 14 to 24 percent. The purpose of this retrospective study was to investigate the morbidity and mortality of patients diagnosed with stage III NSCLC and treated with pneumonectomy at the University of Kentucky Medical Center in Lexington, KY. Methods: We reviewed the medical record and tumor registry follow-up data on 100 consecutive patients who underwent pneumonectomy for lung cancer at the University of Kentucky. Results: We identified thirty-six patients in stage III who underwent pneumonectomy. Ten patients had surgery only, eight patients received adjuvant chemotherapy, and eighteen patients received neoadjuvant therapy. There was one surgical death in this series. Mean follow-up was 2.9 years. One-, three-, and five-year survival was 66%, 38%, and 38%, respectively. Five-year survival for the group with adjuvant therapy was 60%. Conclusion: Most lung cancer patients present with advanced disease and the prognosis remains poor. Our experience indicates resection offers an above average chance of long-term survival when supplemented with neoadjuvant and/or adjuvant therapy.

    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.

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

    Full Text Available Systemic therapy for non-small cell lung cancer (NSCLC has undergone a dramatic paradigm shift over the past decade. Advances in our understanding of the underlying biology of NSCLC have revealed distinct molecular subtypes. A substantial proportion of NSCLC depends on oncogenic molecular aberrations (so-called “driver mutations” for their malignant phenotype. Personalized therapy encompasses the strategy of matching these subtypes with effective targeted therapies. EGFR mutations and ALK translocation are the most effectively targeted oncogenes in NSCLC. EGFR mutations and ALK gene rearrangements are successfully being targeted with specific tyrosine kinase inhibitors. The number of molecular subgroups of NSCLC continues to grow. The scope of this review is to discuss recent data on novel molecular targets as ROS1, BRAF, KRAS, HER2, c-MET, RET, PIK3CA, FGFR1 and DDR2. Thereby the review will focus on therapeutic strategies targeting these aberrations. Moreover, the emerging challenge of acquired resistance to initially effective therapies will be discussed.

    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.

    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.%表皮生长因子受体酪氨酸激酶抑制剂(epidermal growth factor receptor tyrosine kinase inhibitors,EGFRTKIs)在晚期非小细胞肺癌患者(non-small cell lung cancer,NSCLC)中的应用越来越广泛,但患者的疗效存在明显差异.目前主要是根据EGFR基因突变来选择患者,然而,其检测常受到肿瘤组织来源困难、技术复杂、费用高等因素限制.因此,临床亟待寻求其他生物学标记物来预测EGFR-TKIs疗效.近来有诸多研究发现EGFR基因多态性与晚期NSCLC患者EGFR-TKIs疗效及预后也存在相关性,现将其研究进展作一综述.

    Early identification and treatment of nutritional deficiencies can lead to improved outcomes in the quality of life (QoL) and survival of patients with nonsmall cell lung cancer (NSCLC). Noninvasive techniques are needed to evaluate changes in body composition as part of determining nutritional status. The aim of the study was to evaluate the association of nutritional parameters in health-related quality of life (HRQL) and survival in patients with advanced NSCLC. Chemotherapy-naïve patients with advanced NSCLC with good performance status Eastern Cooperative Oncology Group (ECOG) 0-2 were included prospectively in the study. We evaluated inflammatory parameters such as C-reactive protein, platelet/lymphocyte index, neutrophil/lymphocyte index, serum interleukin (IL)-6, and tumor necrosis factor-α, and nutritional variables such as body mass index (BMI) and serum albumin levels. Bioelectrical impedance analysis including phase angle was obtained before cisplatin-based chemotherapy was started. HRQL was assessed by application of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ)-C30 and QLQ-LC13 instruments at baseline. Overall survival (OS) was calculated with the Kaplan-Meier method and analyzed with log-rank and Cox proportional hazard models. One hundred nineteen patients were included. Mean BMI was 24.8 ± 4.5 kg/m(2), average weight loss of patients was 8.4%, and median phase angle was 5.8°. Malnutrition measured by subjective global assessment (SGA), weight loss >10%, BMI >20 was associated with lower HRQL scales. Patients with ECOG 2, high content serum IL-6, lower phase angle, and malnutrition parameters showed lower OS; however, after multivariate analysis, only ECOG 2 [Hazard ratio (HR), 2.7; 95% confidence interval (95% CI), 1.5-4.7; P = 0.001], phase angle ≤5.8° (HR = 3.02; 95% CI: 1.2-7.11; P = 0.011), and SGA (HR = 2.7; 95% CI, 1.31-5.5; P = 0.005) were associated with poor survival.

The majority of patients bear nonsmall cell lung cancer ( NSCLC ). And most of them have already locally advanced or distant metastasis when clinical diagnose. The most common histological type is adenocarcinoma, followed by squamous cell carcinoma, large cell carcinoma and undifferentiated carcinoma, et al. For patients of good performance status ( PS ) scores, platinum -based double - agent regimen could prolong survival period, improve quality of life and reduce tumor - related symptoms. Without clinical benefit, the addition of a third cytotoxic drug could only increase toxicity. It's tumor molecular markers that show great significance on chemotherapy drug options and treatment efficacy prediction. Patients will receive better survival benefits if we combines platinum -based double -agent regimen with molecular targeted drug,such as bevacizumab. Such patients must meet non -squamous cell carcinoma, PS score ≤ 1, no brain metastases,no hemoptysis, no uncontrolled hypertension and no need of anticoagulant therapy. Low PS score patients, as chemotherapy brings little clinical benefits, are currently recommended single -agent chemotherapy. It's also the standard chemotherapy of most elderly patients ( ≥ 70 years old ), who are thought to

    Highlights: • Disulfiram and copper synergistically inhibit lung cancer cell proliferation. • Lung cancer cell colony formation ability is inhibited by Disulfiram/copper. • Disulfiram/copper increases the sensitivity of cisplatin to lung cancer cells. • Lung cancer stem cells are specifically targeted by Disulfiram/copper complex. - Abstract: Non-small cell lung cancer (NSCLC) is the most common cause of cancer-related death in both men and women worldwide. Recently, Disulfiram has been reported to be able to inhibit glioblastoma, prostate, or breast cancer cell proliferation. In this study, the synergistic effect of Disulfiram and copper on NSCLC cell growth was investigated. Inhibition of cancer cell proliferation was detected by 1-(4,5-Dimethylthiazol-2-yl)-3,5-diphenylformazan (MTT) assay and cell cycle analysis. Liquid colony formation and tumor spheroid formation assays were used to evaluate their effect on cancer cell clonogenicity. Real-time PCR was performed to test the mRNA level of cancer stem cell related genes. We found that Disulfiram or copper alone did not potently inhibit NSCLC cell proliferation in vitro. However, the presence of copper significantly enhanced inhibitory effect of Disulfiram on NSCLC cell growth, indicating a synergistic effect between Disulfiram and copper. Cell cycle analysis showed that Disulfiram/copper complex caused NSCLC cell cycle arrest in G2/M phase. Furthermore, Disulfiram/copper significantly increased the sensitivity of cisplatin in NSCLC cells tested by MTT assay. Liquid colony formation assay revealed that copper dramatically increased the inhibitory effect of Disulfiram on NSCLC cell colony forming ability. Disulfiram combined with copper significantly attenuated NSCLC cell spheroid formation and recuded the mRNA expression of lung cancer stem cell related genes. Our data suggest that Disulfiram/copper complex alone or combined with other chemotherapy is a potential therapeutic strategy for NSCLC patients.

    In this work, we demonstrated that the growth of human non-small-cell-lung-cancer cells H460 and A549 cells can be inhibited by low concentrations of an epoxide derivative, teroxirone, in both in vitro and in vivo models. The cytotoxicity was mediated by apoptotic cell death through DNA damage. The onset of ultimate apoptosis is dependent on the status of p53. Teroxirone caused transient elevation of p53 that activates downstream p21 and procaspase-3 cleavage. The presence of caspase-3 inhibitor reverted apoptotic phenotype. Furthermore, we showed the cytotoxicity of teroxirone in H1299 cells with stable ectopic expression of p53, but not those of mutant p53. A siRNA-mediated knockdown of p53 expression attenuated drug sensitivity. The in vivo experiments demonstrated that teroxirone suppressed growth of xenograft tumors in nude mice. Being a potential therapeutic agent by restraining cell growth through apoptotic death at low concentrations, teroxirone provides a feasible perspective in reversing tumorigenic phenotype of human lung cancer cells. - Highlights: • Teroxirone repressed tumor cell growth in nude mice of human lung cancer cells. • The apoptotic cell death reverted by caspase-3 inhibitor is related to p53 status. • Teroxirone provides a good candidate for lung cancer treatment.

    Full Text Available Purpose: Measurement of the number of circulating tumor cells (CTCs in the bloodstream has been shown to have prognostic significance in treating breast carcinoma. This pilot study was formulated to determine if stage IV non-small cell lung carcinomas similarly shed malignant cells into the circulation and if their presence has prognostic significance. Methods: Patients with stage IV non-small cell lung carcinomas were tested once for CTCs in 7.5 ml of their blood prior to receiving any treatments. A proprietary blood collection kit produced by Veridex LLC (Raritan, NJ, which manufactures the instrument that performs the immunomagnetic CELLSEARCH® CTC assay, was used. Tumor measurements were determined in three dimensions by the same radiologist using computerized axial tomography. The three-dimensional sum was used to represent tumor size. Survival from the date of the pretreatment CTC assay was monitored and recorded. Data were analyzed statistically using NCSS8 statistical software (NCSS LLC, Kaysville, UT. Results: Of 19 evaluable patients, 10 had no detectable CTCs. There was no relation between intrapulmonary primary tumor size and the number of CTCs, nor between tumor size and survival. Survival was not affected by gender or age at entry into the trial. The mean survival of those with no detectable CTCs was 536 ± 91.1 days versus 239 ± 96.0 days for those with 1 or more detectable CTCs, a statistically significant advantage (P=0.034 favoring those without CTCs. Conclusions: Patients with a CTC score of 0 survived significantly longer than those with a CTC score of ≥ 1. Survival was not correlated with gender, age or primary tumor size. Recovery of CTCs potentially provides a noninvasive source of tumor cells for genomic profiling, which may enable development of a custom treatment plan for the individual patient. Further investigations are warranted and needed.

    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.

    Changes in WIFI expression, an extracellular inhibitor of Wnt pathway, in non-small cell lung carcinomas were analyzed. Frequent (67% cases) suppression of WIFI transcript in non-small cell lung carcinomas were found. Our results, together with previously published data, suggest that inhibition of WIFI expression often occurs in squamous cell carcinomas and is less typical of adenocarcinomas. It was also found that a decrease in the WIFI transcript in tumors is parallel to concomitant suppression of the WIFI protein level. Our results provide further evidence that the WIFI suppression is a frequent event in the lung carcinogenesis, which might lead to disregulation of Wnt signaling pathway and contribute to tumor progression.

    Recent studies indicate that the transient receptor potential canonical 6 (TRPC6) channel is highly expressed in several types of cancer cells. However, it remains unclear whether TRPC6 contributes to the malignancy of human non-small cell lung cancer (NSCLC). We used a human NSCLC A549 cell line as a model and found that pharmacological blockade or molecular knockdown of TRPC6 channel inhibited A549 cell proliferation by arresting cell cycle at the S-G2M phase and caused a significant portion of cells detached and rounded-up, but did not induce any types of cell death. Western blot and cell cycle analysis show that the detached round cells at the S-G2M phase expressed more TRPC6 than the still attached polygon cells at the G1 phase. Patch-clamp data also show that TRPC whole-cell currents in the detached cells were significantly higher than in the still attached cells. Inhibition of Ca2+-permeable TRPC6 channels significantly reduced intracellular Ca2+ in A549 cells. Interestingly, either blockade or knockdown of TRPC6 strongly reduced the invasion of this NSCLC cell line and decreased the expression of an adherent protein, fibronectin, and a tight junction protein, zonula occluden protein-1 (ZO-1). These data suggest that TRPC6-mediated elevation of intracellular Ca2+ stimulates NSCLC cell proliferation by promoting cell cycle progression and that inhibition of TRPC6 attenuates cell proliferation and invasion. Therefore, further in vivo studies may lead to a consideration of using a specific TRPC6 blocker as a complement to treat NSCLC. PMID:28030826

    Objective To investigate the effects of bisdemethoxycurcumin (BDMC) on non-small cell lung cancer (NSCLC) cell line, A549, and the highly metastatic lung cancer 95D cells. Methods CCK-8 assay was used to assess the effect of BDMC on cytotoxicity. Flow cytometry was used to evaluate apoptosis. Western blot analysis, electron microscopy, and quantification of GFP-LC3 punctuates were used to test the effect of BDMC on autophagy and apoptosis of lung cancer cells. Results BDMC inhibited the viability of NSCLC cells, but had no cytotoxic effects on lung small airway epithelial cells (SAECs). The apoptotic cell death induced by BDMC was accompanied with the induction of autophagy in NSCLC cells. Blockage of autophagy by the autophagy inhibitor 3-methyladenine (3-MA) repressed the growth inhibitory effects and induction of apoptosis by BDMC. In addition, BDMC treatment significantly decreased smoothened (SMO) and the transcription factor glioma-associated oncogene 1 (Gli1) expression. Furthermore, depletion of Gli1 by siRNA and cyclopamine (a specific SMO inhibitor) induced autophagy. Conclusion Aberrant activation of Hedgehog (Hh) signaling has been implicated in several human cancers, including lung cancers. The present findings provide direct evidence that BDMC-induced autophagy plays a pro-death role in NSCLC, in part, by inhibiting Hedgehog signaling.

    Background Osteopontin (OPN) was identified as one of the leading genes that promote the metastasis of malignant tumor.However,the mechanism by which OPN mediates metastasis in non-small cell lung cancer (NSCLC) remains unknown.The aim of the study is to investigate the biological significance and the related molecular mechanism of OPN expression in lung cancer cell line.Methods Lentiviral-mediated RNA interference was applied to inhibit OPN expression in metastatic human NSCLC cell line (A549).The invasion,proliferation,and metastasis were evaluated OPN-silenced in A549 cells in vitro and in vivo.The related mechanism was further investigated.Results Interestingly,OPN knockdown significantly suppressed the invasiveness of A549 cells,but had only a minor effect on the cellular migration and proliferation.Moreover,we demonstrated that OPN knockdown significantly reduced the levels of matrix metalloproteinase (MMP)-2 and urokinase plasminogen activator (uPA),and led to an obviousinhibition of both in vitro invasion and in vivo lung metastasis of A549 cells (P <0.001).Conclusions Our data demonstrate that OPN contributes to A549 cell metastasis by stimulating cell invasion,independent of cellular migration and proliferation.OPN could be a new treatment target of NSCLC.

    Non-small cell lung cancer (NSCLC) is the most common cause of cancer-related death in both men and women worldwide. Recently, Disulfiram has been reported to be able to inhibit glioblastoma, prostate, or breast cancer cell proliferation. In this study, the synergistic effect of Disulfiram and copper on NSCLC cell growth was investigated. Inhibition of cancer cell proliferation was detected by 1-(4,5-Dimethylthiazol-2-yl)-3,5-diphenylformazan (MTT) assay and cell cycle analysis. Liquid colony formation and tumor spheroid formation assays were used to evaluate their effect on cancer cell clonogenicity. Real-time PCR was performed to test the mRNA level of cancer stem cell related genes. We found that Disulfiram or copper alone did not potently inhibit NSCLC cell proliferation in vitro. However, the presence of copper significantly enhanced inhibitory effect of Disulfiram on NSCLC cell growth, indicating a synergistic effect between Disulfiram and copper. Cell cycle analysis showed that Disulfiram/copper complex caused NSCLC cell cycle arrest in G2/M phase. Furthermore, Disulfiram/copper significantly increased the sensitivity of cisplatin in NSCLC cells tested by MTT assay. Liquid colony formation assay revealed that copper dramatically increased the inhibitory effect of Disulfiram on NSCLC cell colony forming ability. Disulfiram combined with copper significantly attenuated NSCLC cell spheroid formation and recuded the mRNA expression of lung cancer stem cell related genes. Our data suggest that Disulfiram/copper complex alone or combined with other chemotherapy is a potential therapeutic strategy for NSCLC patients.

    Background and objective Pemetrexed have been approved for the treatment of patients affected by advanced non-small cell lung cancner (NSCLC) in progression after first-line chemotherapy. We evaluated the activity and feasibility of pemetrexed in previously treated NSCLC.Methods Patients with histologically or cytologically confirmed NSCLC were evaluated from April 2007 to March 2009. The patients had relapsed or progressed after prior chemotherapy treatment. Pemetrexed (500 mg/m2) was administered intravenously once every 3 weeks after progression to prior chemotherapy. The tumor response was evaluated according to RECIST criteria by chest CT at every 2 cycles of chemotherapy.Results A total 61 patients were eligible for analysis. Performance status of them (100%) was over 2. The response rate and disease control rate were 14.7% and 37.7% respectively. Non-squamous cell carcinoma histology was significantly associated with a superior response rate (P=0.045) and disease control rate (P=0.008). The median survival time and the median progression free survival (PFS) time were 6.11 months and 2.17 months, respectively. Comparing the efficacy of pemetrexed in these two settings [second-line versus (12/61) more than third (49/61)], there was no significant difference in regard to median survival (11.18 months vs 11.46 months, P=0.922,S), but PFS was more longer in third- or further-line groups than second-line group (1.39 months vs 2.25 months, P=0.015,3).Conclusion Pemetrexed is a feasible regimen in previously treated NSCLC with poor performance status.

    BRAF mutation is one of driver mutations in non⁃small cell lung cancer(NSCLC). BRAF mutation rate is about 0�5%~4�9%, and more than half of BRAF mutation is V600E. BRAF mutation occurs more commonly in female patients with adeno⁃carcinoma, and the mutation rate is much lower in Asian people. The clinical significance of coexistence of BRAF mutation and other mutations, such as EGFR and K⁃Ras mutations was yet unknown. Given the huge global burden of lung cancer, progress of BRAF mu⁃tation studies hold significant importance, despite its low mutation rate overall. Currently, several BRAF inhibitors are being studied in clinical trials for patients with NSCLC. This review is intended to outline the recent advances of BRAF mutation and its targeted therapy in NSCLC.%鼠类肉瘤病毒癌基因同源物B1( BRAF)基因是非小细胞肺癌( NSCLC)的驱动基因之一,在NSCLC中突变率为0�5%~4�9%,其中V600E突变类型占到一半以上。 BRAF突变多见于女性、肺腺癌患者,亚裔人群中突变率相对较低。BRAF突变可与其他基因突变,如EGFR、K⁃Ras突变共存,但其临床意义尚不清楚。全球NSCLC患者数量庞大,尽管BRAF突变率在NSCLC中较低,低突变率基因及其靶向治疗的研究仍然相当重要。目前BRAF抑制剂治疗NSCLC正在临床试验中。本文就NSCLC中BRAF突变及靶向治疗的研究进展进行综述。

    Full Text Available Abstract Evasion of apoptosis is a hallmark of tumorigenesis and a recognised cause of multidrug resistance. Over the last decade, insights into how apoptosis might be exploited in non-small cell lung cancer (NSCLC and how cancer therapeutics might be used to engage apoptotic signalling in a personalised manner have changed markedly. We are now in the wake of a paradigm shift in stratified therapeutic approaches related to NSCLC. At the heart of this shift in thinking is the emerging knowledge that even the most drug-resistant cancers exhibit a functional death pathway and, critically, that this pathway can be efficiently engaged, leading to clinical benefit. This review will summarise current knowledge of mitochondrial apoptotic pathway dysfunction in NSCLC and how the next generation of targeted therapeutics might be used to exploit deficiencies in apoptotic signalling in a personalised manner to improve clinical outcome and predict therapeutic benefit.

    2013-03-01

    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.

    Non-small cell lung cancer, as the most frequent type lung cancer, has lower survival rate of 5 years, despite improvements in surgery and chemotherapy. Previous studies showed immature colon carcinoma transcript 1 is closely related to tumorigenesis of human cancer cells. In the present study, we found immature colon carcinoma transcript 1 was overexpressed in lung cancer tissues using Oncomine database mining, and the biological effect of immature colon carcinoma transcript 1 was investigated in non-small cell lung cancer cell lines 95D and A549. Lentivirus-mediated RNA interference was used to knock down immature colon carcinoma transcript 1 expression in 95D and A549 cells in vitro, and the knockdown efficiency was determined using quantitative real-time polymerase chain reaction and Western blot assay. Knockdown of immature colon carcinoma transcript 1 significantly suppressed non-small cell lung cancer cell proliferation and colony formation ability confirmed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and colony formation assay. Flow cytometry was applied to measure cell cycle arrest, and the result showed the cell cycle arrested in G2/M phase in 95D cells and arrested in G0/G1 phase in A549 cells. Furthermore, we measured the levels of cell cycle-associated proteins by Western blot analysis and found immature colon carcinoma transcript 1-mediated cell proliferation inhibition appeared due to downregulation of cell cycle activator cyclin D1 and upregulation of cell cycle inhibitor p21. In addition, immature colon carcinoma transcript 1 silencing significantly induced non-small cell lung cancer cell apoptosis by annexin V/7-amino-actinomycin D double-staining assay. All our data suggest that immature colon carcinoma transcript 1 may play an important role for non-small cell lung cancer cell proliferation and could be a potential molecular target for diagnosing and treating human non-small cell lung cancer.

    吴国明; 钱桂生

    2012-01-01

    Currently, molecularly target therapy has increasingly altered the strategies in advanced non-small cell lung cancer ( NSCLC). Epidermal growth factor receptor tyrosine kinase inhibitors ( EGFR-TKIs) , gefitinib and erlotinib, are regarded as the most successful target drugs. However, EGFR-TKIs resistance has become a major clinical challenge. EGFR-TKIs resistance includes the primary resistance and the acquired resistance. The primary resistance' s mechanisms are associated with other non-sensitive EGFR mutations such as exon 20 insertions and other gene mutations such as KRAS, BRAF and EML4-ALK. The acquired resistance' s mechanisms are often associated with the secondary T790 mutation and MET gene amplification. At present, new strategies in overcoming EGFR-TKIs resistance are mainly focusing on irreversible EGFR inhibitors and MET inhibitors.

    Amit Dutt

    Full Text Available BACKGROUND: Squamous cell lung carcinomas account for approximately 25% of new lung carcinoma cases and 40,000 deaths per year in the United States. Although there are multiple genomically targeted therapies for lung adenocarcinoma, none has yet been reported in squamous cell lung carcinoma. METHODOLOGY/PRINCIPAL FINDINGS: Using SNP array analysis, we found that a region of chromosome segment 8p11-12 containing three genes-WHSC1L1, LETM2, and FGFR1-is amplified in 3% of lung adenocarcinomas and 21% of squamous cell lung carcinomas. Furthermore, we demonstrated that a non-small cell lung carcinoma cell line harboring focal amplification of FGFR1 is dependent on FGFR1 activity for cell growth, as treatment of this cell line either with FGFR1-specific shRNAs or with FGFR small molecule enzymatic inhibitors leads to cell growth inhibition. CONCLUSIONS/SIGNIFICANCE: These studies show that FGFR1 amplification is common in squamous cell lung cancer, and that FGFR1 may represent a promising therapeutic target in non-small cell lung cancer.

    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.

    Purpose The standard of care in Locally-Advanced Non-Small Cell Lung Cancer (LA-NSCLC) is chemotherapy and radiation; however, Radiation-Induced Lung Injury (RILI), which may be prevented by the anti-inflammatory and anti-oxidant properties of Flaxseed (FS), impedes its maximum benefit. Materials and Methods Patients with LA-NSCLC requiring definitive RT were randomized to one FS or control muffin daily from start to 2 weeks after RT. Blood and urine were collected to quantify plasma FS metabolites, Enterodione (ED) and Enterolactone (EL), and urinary oxidative stress biomarkers, 8, 12-iso-iPF2a-VI (isoprostane) and 8-oxo-7,8-dihydro-2′deoxyguanosine (8-oxo-dGuo). Tolerability was defined as consuming ≥ 75% of the intended muffins and no ≥ grade 3 gastrointestinal toxicities. Results Fourteen patients (control,7; FS,7) were enrolled. The tolerability rates were 42.9 versus 71.4% (p=0.59) for FS and control, respectively. Mean percentages of intended number of muffins consumed were 37% versus 73% (p=0.12). ED and EL increased at onset of FS and decreased with discontinuation, confirming bioavailability. Isoprostane and 8-oxo-dGuo were detectable. There was a trend towards decreased rates of pneumonitis in FS. Conclusions This is the first study to report FS bioavailability and quantify oxidative stress markers in NSCLC patients. FS in the administered muffin formulation did not meet tolerability criteria. Given the promising mechanism of FS as a radioprotectant, further investigations should focus on the optimal method for administration of FS. PMID:24575360

    Error and variation in reporting remains one of the weakest features of clinical imaging despite enormous technological advances in nuclear medicine and radiology. The aim of this study was to evaluate agreement amongst experienced readers in staging non-small-cell lung cancer (NSCLC) with PET-CT. A series of {sup 18}F-FDG PET-CT scans from 100 consecutive patients were reviewed independently by three experienced readers, with two readers reviewing each scan series a second time. Individual mediastinal lymph node stations were assessed as benign/inflammatory, equivocal or malignant, and AJCC N and M stage were also assigned. Kappa ({kappa}) was used to compare ratings from two categories and weighted kappa ({kappa}{sub w}) for three or more categories, and kappa values were interpreted according to the Landis-Koch benchmarks. Both intra- and interobserver agreement for N and M staging were high. For M staging there was almost perfect intra- and interobserver agreement ({kappa} = 0.90-0.93). For N staging, agreement was either almost perfect or substantial (intraobserver {kappa}{sub w} = 0.79, 0.91; interobserver {kappa}{sub w} = 0.75-0.81). Importantly, there was almost perfect agreement for N0/1 vs N2/3 disease ({kappa} = 0.80-0.97). Agreement for inferior and superior mediastinal nodes (stations 1, 2, 3, 7, 8, 9) was either almost perfect or substantial ({kappa}{sub w} = 0.71-0.88), but lower for hilar nodes (10; {kappa}{sub w} = 0.56-0.71). Interreporter variability was greatest for aortopulmonary nodes (5, 6; {kappa}{sub w} = 0.48-0.55). Amongst experienced reporters in a single centre, there was a very high level of agreement for both mediastinal nodal stage and detection of distant metastases with PET-CT. This supports the use of PET-CT as a robust imaging modality for staging NSCLC. (orig.)

    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.

However, the underlying mechanism remains largely unclear. Investigation on special therapeutic targets associated with radioresistance shows promises for the enhancement of clinical radiotherapy effect toward NSCLC. This study aimed to reveal the role of Stathmin1 (STMN1 in radioresistance in NSCLC as well as the underlying mechanism. Our data showed that the protein levels of STMN1 were significantly upregulated in NSCLC cells subjected to radiation, accompanied with the activation of autophagy. Knockdown of STMN1 expression enhanced the sensitivity of NSCLC cells to X-ray, and the radiation-induced autophagy was also inhibited. Molecular mechanism investigation showed that knockdown of STMN1 expression upregulated the activity of phosphoinositide 3-kinase (PI3K/mammalian target of rapamycin (mTOR signaling pathway in NSCLC cells. Moreover, the activation of PI3K/mTOR signaling showed an inhibitory effect on the autophagy and radioresistance induced by STMN1 in NSCLC cells. In addition, luciferase reporter assay data indicated that STMN1 was a direct target gene of miR-101, which had been reported to be an inhibitor of autophagy. Based on these data, we suggest that as a target gene of miR-101, STMN1 promotes the radioresistance by induction of autophagy through PI3K/mTOR signaling pathway in NSCLC. Therefore, STMN1 may become a potential therapeutic target for NSCLC radiotherapy. Keywords: radioresistance, non-small-cell

    Lung cancer remains the leading cause of cancer-related mortality worldwide and non-small cell lung cancer (NSCLC) accounts for approximately 80-85% of all cases of lung cancer. Cisplatin plays a significant role in the management of human lung cancer. Translesion DNA synthesis (TLS) is involved in DNA damage repair. DNA polymerase ζ (Pol ζ) is able to mediate the DNA replication bypass of DNA damage, which is suggested to be involved in chemoresistance. REV3L is the catalytic subunit of Pol ζ. Due to its critical role in translesion DNA synthesis, whether REV3L modulates cisplatin response in NSCLC cells remains unknown. In this study, REV3L overexpression and silencing H1299 cell lines were established. The reports showed that cisplatin induced the expression of REV3L by recruiting Sp1 to its promoter. Similar results were obtained when the ability of the cells to express luciferase from a platinated plasmid was measured. Co-transfection of the reporter with the REV3L overexpression vector or REV3L plus REV7L significantly enhanced the reporter activity. Nuclear condensation and fragmentation of shRNA-REV3L H1299 cells were more pronounced than shRNA-NC H1299 cells after cisplatin exposure, indicating that REV3L overexpression abolished cisplatin-induced DNA damage. Moreover, a forced expression of REV3L conferred the resistance of H1299 cells to cisplatin, whereas the knockdown of REV3L sensitized cisplatin efficacy in H1299 cells. Taken together, we demonstrated that inhibition of REV3L sensitized lung cancer H1299 cells to cisplatin treatment. Thus, REV3L may be a novel target for the chemotherapy of NSCLC.

    Insulin plays an important role as a growth factor and its contribution to tumor proliferation is intensely discussed. It acts via the cognate insulin receptor (IR) but can also activate the IGF1 receptor (IGF1R). Apart from increasing proliferation, insulin might have additional effects in lung cancer. Therefore, we investigated insulin action and effects of IR knockdown (KD) in three (NCI-H292, NCI-H226 and NCI-H460) independent non-small cell lung cancer (NSCLC) cell lines. All lung cancer lines studied were found to express IR, albeit with marked differences in the ratio of the two variants IR-A and IR-B. Insulin activated the classical signaling pathway with IR autophosphorylation and Akt phosphorylation. Moreover, activation of MAPK was observed in H292 cells, accompanied by enhanced proliferation. Lentiviral shRNA IR KD caused strong decrease in survival of all three lines, indicating that the effects of insulin in lung cancer go beyond enhancing proliferation. Unspecific effects were ruled out by employing further shRNAs and different insulin-responsive cells (human pre-adipocytes) for comparison. Caspase assays demonstrated that IR KD strongly induced apoptosis in these lung cancer cells, providing the physiological basis of the rapid cell loss. In search for the underlying mechanism, we analyzed alterations in the gene expression profile in response to IR KD. A strong induction of certain cytokines (e.g. IL20 and tumour necrosis factor) became obvious and it turned out that these cytokines trigger apoptosis in the NSCLC cells tested. This indicates a novel role of IR in tumor cell survival via suppression of pro-apoptotic cytokines.

    Currently, chemotherapy with platinum-based drugs including cisplatin is the most effective therapy for the treatment of non-small cell lung carcinoma (NSCLC). However, the efficacy of chemotherapy is limited due to commonly developed drug resistance. Spindle and kinetochore-associated complex subunit 1 (SKA1) is part of a complex essential for stabilizing the attachment of spindle microtubules to kinetochores and for maintaining the metaphase plate during mitosis. In the present study, we aimed to investigate the role of SKA1 in the process of metastasis and drug resistance of NSCLC. We completed a series of experiments to investigate the function of SKA1 in NSCLC metastasis and drug resistance including qRT-PCR, immunohistochemistry and western blotting, as well as MTT, BrdU, wounded healing, Transwell and gelatin zymography assays. We demonstrated that the expression levels of SKA1 were elevated in NSCLC and were correlated with cancer progression and malignancy. We also reported that SKA1 positively regulated the proliferation and metastatic ability of NSCLC cells. In addition, we determined that SKA1 contributed to cisplatin resistance in NSCLC cells by protecting these cells from cisplatin-induced cell apoptosis. SKA1 also appeared to regulate the ERK1/2 and the Akt-mediated signaling pathways in NSCLC cells. SKA1 is required for metastasis and cisplatin resistance of non-small cell lung cancer.

    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.)

    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.

    Lung cancer remains interdisciplinary problem. The genetic alterations in non-small cell lung cancer (NSCLC) are related to tumor suppressor genes and proto-oncogenes. CCND1 gene, coding cyclin DI, in correlation with pRb is involved in regulation of cell cycle arrest in G1 phase. Amplification of CCND1 gene and cyclin D1 over-expression was found in several cancers including head and neck cancers or colorectal cancer, where these alterations were correlated with worse prognosis. The literature addressing the clinical significance of CCND1 gene amplification/expression in NSCLC remains poor and prognostic value of these alterations in that cancer is still controversial.

    Full Text Available Xiaoting Zhao, Yinan Guo, Wentao Yue, Lina Zhang, Meng Gu, Yue Wang Department of Cellular and Molecular Biology, Beijing TB and Thoracic Tumor Research Institute/Beijing Chest Hospital, Capital Medical University, Beijing, People's Republic of China Background: Multidrug resistance protein 4 (MRP4, also known as ATP-cassette binding protein 4 (ABCC4, is a member of the MRP/ABCC subfamily of ATP-binding cassette transporters, which are capable of pumping a wide variety of drugs out of the cell. However, little is known about the function of ABCC4 in the proliferation of lung cancer cells. Methods: ABCC4 mRNA and protein levels in lung cancer cell lines were measured by real-time polymerase chain reaction and Western blot, respectively. A lentivirus-mediated RNA interference technique was used to inhibit ABCC4 mRNA expression in A549 and 801D cells. The function of ABCC4 in cell growth was investigated by MTS and colony formation assays. The role of ABCC4 in cell cycle progression was evaluated by flow cytometry and Western blot analysis. ABCC4 mRNA levels in 30 pairs of tumors and corresponding matched adjacent normal tissues from non-small cell lung cancer patients were detected by real-time polymerase chain reaction. Results: ABCC4 was highly expressed in lung cancer cell lines. ABCC4 expression was markedly downregulated in A549 and 801D cells using the RNA interference technique. Suppression of ABCC4 expression inhibited cell growth. The percentage of cells in G1 phase was increased when ABCC4 expression was suppressed. Phosphorylation of retinoblastoma protein was weakened, originating in the downregulation of ABCC4. ABCC4 mRNA was highly expressed in lung cancer tissue and lung cancer cell lines. Conclusion: ABCC4 may play an important role in the control of A549 and 801D cell growth. ABCC4 is a potential target for lung cancer therapy.

Here, we found that SAMD9 is down-regulated in human non-small cell lung cancer (NSCLC). Furthermore, knockdown of SAMD9 expression is increased the invasion, migration and proliferation in H1299 cells in vitro and overexpression of SAMD9 suppressed proliferation and invasion in A549 cells. Finally, depletion of SAMD9 increases tumor formation in vivo. Our results may provide a strategy for blocking NSCLC tumorigenesis and progression.

    Through epithelial-mesenchymal transition (EMT), cancer cells acquire enhanced ability of migration and invasion, stem cell like characteristics and therapeutic resistance. Notch signaling regulates cell-cell connection, cell polarity and motility during organ development. Recent studies demonstrate that Notch signaling plays an important role in lung cancer initiation and cross-talks with several transcriptional factors to enhance EMT, contributing to the progression of non-small cell lung cancer (NSCLC). Correspondingly, blocking of Notch signaling inhibits NSCLC migration and tumor growth by reversing EMT. Clinical trials have showed promising effect in some cancer patients received treatment with Notch1 inhibitor. This review attempts to provide an overview of the Notch signal in NSCLC: its biological significance and therapeutic application.

    Objective: The aim of this study was to evaluate the clinical efficacy and side effects of docetaxel/cisplatin regiment and gemcitabine/cisplatin regiment in the patients with advanced non-small-cell lung cancer (NSCLC). Methods: Seventy-six patients with advanced NSCLC who were chemotherapy-naive were enrolled in two groups. In docetaxel group (DP group) the patients received docetaxe175 mg/m2 and cisplatin 60 mg/m2 on day 1. In gemcitabine group (GP group) the patients received gemcitabine 1000 mg/m2 on day 1 and day 8. The dosage of cisplatin was the same as DP group. The two regiments were administrated intravenously every 21 days as a cycle, each patient received 2-4 cycles. All patients were followed up until disease progressed or patients died. Results: The overall response rates were 43.5% in DP group and 45.9% in GP group. The response rate was significantly different between the initial treated group and retreated group in both two groups (53.8% vs 23.0% in DP group and 56% vs 25% in GP group, P < 0.05, respectively). The main side effects were bone marrow suppression and thrombocytopenia. Conclusion: Docetaxel/cisplatin regiment and gemcitabine/cisplatin regiment for the patients with advanced NSCLC were efficient and well-tolerated chemotherapeutic approachs with Iow toxicity levels. The efficacy and major toxicity in two groups were similar.

    Gefitinib is effective in only approximately 20% of patients with non-small-cell lung cancer (NSCLC),and the underlying mechanism remains unclear.FoxM1 is upregulated in NSCLC and associated with a poor prognosis in NSCLC patients.In this study,we examined the possible role of FoxM1 in gefitinib resistance and the related mechanisms.Methods:Gefitinib resistant human lung adenocarcinoma cell line SPC-A-1 and gefitinib-sensitive human lung mucoepidermoid carcinoma cell line NCI-H292 were used.mRNA and protein expression of FoxM1 and other factors were tested with quantitative RT PCR and Western blot analysis.RNA interference was performed to suppress FoxM1 expression in SPC-A-1 cells,and lentiviral infection was used to overexpress FoxM1 in H292 cells.MTT assay and flow cytometry were used to examine the proliferation and apoptosis of the cells.Results:Treatment of SPC-A-1 cells with gefitinib (1 and 10 μmol/L) upregulated the expression of FoxM1 in time- and concentrationdependent manners,while gefrtinib (1 μmol/L) downregulated in H292 cells.In SPC-A-1 cells treated with gefitinib (1 μmol/L),the expression of several downstream targets of FoxM1,including survivin,cyclin B1,SKP2,PLK1,Aurora B kinase and CDC25B,were significantly upregulated.Overexpression of FoxM1 increased the resistance in H292 cells,while attenuated FoxM1 expression restored the sensitivity to gefitinib in SPC-A-1 cells by inhibiting proliferation and inducing apoptosis.Conclusion:The results suggest that FoxM1 plays an important role in the resistance of NSCLC cells to gefitinib in vitro.FoxM1 could be used as a therapeutic target to overcome the resistance to gefitinib.

    Objective To explore the effects of adjuvant chemotherapy combined with Kang'ai injection on the expression of serum VEGF in patients with advanced non-small cell lung cancer. Methods Forty-six patients with advanced non-small cell lung cancer were randomly divided equally into two groups. Patients in experimental group were treated with gemcitabine and cisplatin chemotherapy regimen(GP)combined with Kang'ai injection, while patients in the control were just treated with GP regimen chemotherapy. The expression levels of serum vascular endothelial growth factor(sVEGF) were measured by ELISA before and after the treatment,respectively. Results The sVEGF levels of all patients with advanced NSCLC were obviously higher than that of health controls(P<0. 05). And the level of sVEGF in squamous cell cancer group was higher than that in adenocarcinoma, large cell carcinoma or adenosquamous carcinoma group, respectively(P<0. 05),while there was no significant difference between the latter 3 groups(P>0. 05). Compared the well differentiated group, the sVEGF level of moderately and poorly defferentiated group was increased with no significance(P>0. 05). The sVEGF level was obviously decreased in two groups after the treatments(P<0. 05). Furthermore, the sVEGF level was significantly decreased combination therapy group than that in chemotherapy group(P<0. 05). Conclusion Kang'ai injection might decrease the expression of serum VEGF in patients with advanced non-small cell lung cancer which suppressed neovascularization. Serum VEGF could be a biomarker for lung cancer diagnosis and therapeutic effect of chemotherapy or biotherapy.%目的 探讨康艾注射液辅助化疗对晚期非小细胞肺癌患者血清VEGF(sVEGF)表达的干预作用.方法 将入组的46例晚期非小细胞肺癌患者随机分为实验组(康艾注射液联合化疗组,23例)和对照组(单纯化疗组23例),应用酶联免疫吸附法(ELISA)检测患者治疗前后sVEGF表

    Bone metastasis occurs in approximately 30–40% patients with advanced non-small cell lung cancer (NSCLC), but the mechanism underlying this bone metastasis remains poorly understood. The chemokine super family is believed to play an important role in tumor metastasis in lung cancer. The chemokine receptor XCR1 has been identified to promote cell proliferation and migration in oral cancer and ovarian carcinoma, but the role of XCR1 in lung cancer has not been reported. In this study, we demonstrated for the first time that XCR1 was overexpressed in lung cancer bone metastasis as compared with that in patients with primary lung cancer. In addition, the XCR1 ligand XCL1 promoted the proliferation and migration of lung cancer cells markedly, and knockdown of XCR1 by siRNA abolished the effect of XCL1 in cell proliferation and migration. Furthermore, we identified JAK2/STAT3 as a novel downstream pathway of XCR1, while XCL1/XCR1 increased the mRNA level of the downstream of JAK2/STAT3 including PIM1, JunB, TTP, MMP2 and MMP9. These results indicate that XCR1 is a new potential therapeutic target for the treatment of lung cancer bone metastasis. - Highlights: • XCR1 is overexpressed in bone metastasis compared with primary NSCLC. • XCR1 activation by XCL1 promotes lung cancer cell proliferation and migration. • JAK2/STAT3 is a novel potential downstream pathway of XCR1.

    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.

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. Keywords: non-small cell lung cancer, precision medicine, epidermal growth factor receptor, Kirsten rat sarcoma viral oncogene homolog, serine/threonine kinase 11, tumor protein p53

    Lung cancer is the principal cause of cancer-related death worldwide. The use of targeted therapies, especially tyrosine kinase inhibitors (TKIs), in specific groups of patients has dramatically improved the prognosis of this disease, although inevitably some patients will develop resistance to these drugs during active treatment. The most common cancer-associated acquired mutation is the epidermal growth factor receptor (EGFR) Thr790Met (T790M) mutation. During active treatment with targeted therapies, histopathological transformation to small-cell lung carcinoma (SCLC) can occur in 3-15% of patients with non-small-cell lung carcinoma (NSCLC) tumors. By definition, SCLC is a high-grade tumor with specific histological and genetic characteristics. In the majority of cases, a good-quality hematoxylin and eosin (H&E) stain is enough to establish a diagnosis. Immunohistochemistry (IHC) is used to confirm the diagnosis and exclude other neoplasia such as sarcomatoid carcinomas, large-cell carcinoma, basaloid squamous-cell carcinoma, chronic inflammation, malignant melanoma, metastatic carcinoma, sarcoma, and lymphoma. A loss of the tumor-suppressor protein retinoblastoma 1 (RB1) is found in 100% of human SCLC tumors; therefore, it has an essential role in tumorigenesis and tumor development. Other genetic pathways probably involved in the histopathological transformation include neurogenic locus notch homolog (NOTCH) and achaete-scute homolog 1 (ASCL1). Histological transformation to SCLC can be suspected in NSCLC patients who clinically deteriorate during active treatment. Biopsy of any new lesion in this clinical setting is highly recommended to rule out a SCLC transformation. New studies are trying to assess this histological transformation by noninvasive measures such as measuring the concentration of serum neuron-specific enolase.

    Objective: Despite platinum-based adjuvant chemotherapy has improved greatly patients' outcomes, drug resistance poses a major impediment to the successful use of such an effective agent. Metallothioneins(MTs) are known to play putative roles in cancer cell proliferation, apoptosis, differentiation, drug resistance and prognosis. The present studiy was to investigte the role of metallethioein1H(MT1H) in cisplatin resistance of human non-small cell lung cancer(NSCLC) cell lines in vitro or its possible molecular mechanisms. Methods: MT1H mRNA expression in A549 and A549/DDP cells was detected by RT-PCR. A recombinant eukaryotic expression plasmid pcDNA3.1(-)-MT1H was constructed and transfected into A549 cells which express no MT1H. MT1H siRNA was transfected into A549/DDP cells which express MT1H highly. MT1H expression was detected by RT-PCR and Immunoblot. The chemosensitivity to cisplatin was assessed by MTT assay. Apoptosis rate was determined by Tunel and FCM. Bcl-2 and Bax were determined by immunohistochemistry. Results: MT1H mRNA was expressed in A549/DDP but not in A549. After transfection of MT1H, MT1H expression was enhanced and the chemosensitivity to cisplatin was decreased in A549 cells. Inversely, after transfection of MT1H siRNA, MT1H expression was decreased and the chemosensitivity to cisplatin was increased in A549/DDP. The apoptosis rate induced by cisplatin was increased and Bcl-2 was down-regulated but Bax showed little change in A549/DDP cells interferred with MT1H siRNA. Conclusion: MT1H overexpression can promote drug resistance in A549 cells . Down-regulation of MT1H interfered with siRNA can effectively reverses the drug resistance in A549/DDP cells by down-regulating the expression of Bcl-2 and increasing cisplatin induced apoptosis. SiRNA targeting MT1H combined with chemotherapy may be a very promising strategy for treatment of lung cancer.

    Pulmonary artery (PA) agenesis in the absence of associated cardiac abnormalities is a rare congenital abnormality. It may remain undiagnosed until adulthood when patients present with respiratory symptoms such as hemoptysis, dyspnea, repeated respiratory infections, or pulmonary hypertension. Herein we present a case of a 50-year-old woman who was found to have multiple, morphologically distinct non-small cell lung cancers in association with agenesis of the PA. This instance represents the fourth reported case of such association in the English literature.

    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.

    Full Text Available An increasing proportion of patients with advanced NSCLC are over 70 years old, raising unique challenges for treatment decision-making. While these patients are underrepresented in clinical trials, there is an emerging body of evidence associated with this group. The lesson of comprehensive geriatric assessment is that chronological age does not always correlate with physiological age and a variety of important comorbidities and geriatric syndromes can go undetected in a typical history and physical. These comorbidities and expected physiologic changes due to aging complicate decision-making around appropriate treatment. This review discusses geriatric assessment in elderly cancer patients and evaluates the current evidence for chemotherapy and targeted therapy for patients with advanced non-small cell lung cancer aged ≥70 years.
