    2015-06-01

    Cancer anorexia-cachexia syndrome (CACS) is associated with increased morbidity and mortality. Anamorelin is a novel, orally active ghrelin receptor agonist in clinical development for the treatment of CACS in NSCLC. The aim of this review is to summarize preclinical and clinical studies evaluating anamorelin as a potential promising treatment for CACS in NSCLC. Pharmacodynamics, pharmacokinetics and metabolism, clinical efficacy, safety and tolerability of anamorelin for the treatment of CACS in NSCLC were reviewed. Anamorelin administration may lead to increases in food intake, body weight and lean body mass, and a stimulatory effect on growth hormone secretion in NSCLC patients. Anamorelin is well tolerated with no dose-limiting toxicities identified to date. Targeting ghrelin receptors presents the advantage of potentially addressing multiple mechanisms of CACS simultaneously including appetite, muscle protein balance, adipose tissue metabolism, energy expenditure and inflammation. Clinical data suggest that anamorelin is well tolerated and it effectively increases appetite, body weight and lean mass in patients with advanced NSCLC. Long-term safety remains unknown at this time. The potential synergistic effects of anamorelin with nutritional support or exercise as well as its efficacy/safety in other tumor types are also unknown.

    Full Text Available Marianne Davies Smilow Cancer Hospital at Yale-New Haven Hospital, New Haven, CT, USA Abstract: Recent advances in the understanding of immunology and antitumor immune responses have led to the development of new immunotherapies, including vaccination approaches and monoclonal antibodies that inhibit immune checkpoint pathways. These strategies have shown activity in melanoma and are now being tested in lung cancer. The antibody drugs targeting cytotoxic T-lymphocyte-associated antigen-4 and programmed cell death protein-1 immune checkpoint pathways work by restoring immune responses against cancer cells, and are associated with unconventional response patterns and immune-related adverse events as a result of their mechanism of action. As these new agents enter the clinic, nurses and other health care providers will require an understanding of the unique efficacy and safety profiles with immunotherapy to optimize potential patient benefits. This paper provides a review of the new immunotherapeutic agents in development for lung cancer, and strategies for managing patients on immunotherapy.

    Full Text Available Lung cancer is the third most commonly diagnosed cancer and the leading cause of cancer-related death in the United States. Unlike non-squamous NSCLC, squamous NSCLC rarely harbor epidermal growth factor receptor (EGFR and anaplastic lymphoma kinase (ALK mutations for which there are directed therapies, and until the recent approval of immunotherapies for squamous NSCLC, a limited number of traditional cytotoxic chemotherapy drugs have been FDA-approved for use in the treatment of advanced and metastatic squamous NSCLC. Immunotherapies directed at the programmed cell death-1 receptor (PD-1 or its ligand (PD-L1 (nivolumab and pembrolizumab have demonstrated efficacy in both nonsquamous and squamous cell NSCLC. Because of their similar mechanism of action against the PD-L1/PD-1 pathway, both drugs have similar toxicity profiles related to immune-mediated adverse reactions that can generally be monitored and managed with oral corticosteroids. This paper provides an overview of drug therapy options for squamous cell NSCLC with a focus on the evidence and clinical application of the anti-PD1 therapies. A comparison of the dosing, administration, indications, and differences in the measurement of PD-L1 expression in the clinical trials of nivolumab and pembrolizumab is also provided.

    Recent advances in the treatment of non-small cell lung cancer (NSCLC) have led to improvements in patient survival and quality of life. It is unclear whether molecular abnormalities associated with NSCLC cell survival, growth and proliferation are useful in predicting treatment benefit. We conducted a systematic review to establish which biomarkers contribute meaningfully to the management of NSCLC. A team of researchers searched PubMed and conference proceedings (ASCO, ESMO, IASLC, USCAP) using MESH terms for NSCLC and randomized trials (RCT), plus keywords for variables of interest. Evidence from multiple RCTs confirmed that histologic subtype is prognostic for survival and predictive of treatment efficacy and/or toxicity in NSCLC. Likewise, activating mutations of the epidermal growth factor receptor (EGFR) are associated with benefit from EGFR tyrosine kinase inhibitors in patients with advanced non-squamous NSCLC and should be assessed routinely. No biomarkers to date reliably predict response to anti-Vascular Endothelial Growth Factor (VEGF) therapies. There are inconsistent data on the role of ERCC1, BRCA, Beta tubulin III, RRM1, K-RAS, or TP-53 in treatment decisions. These tests should not be routinely used in selecting treatment at this time, whereas EML4/ALK translocations predict responses to specific targeted agents, the optimal assessment of this molecular abnormality has yet to be established. Personalized care of patients with NSCLC based on biomarkers is increasingly important to both clinical practice and research.

    XL-184 (BMS-907351), under development by Exelixis Inc and Bristol-Myers Squibb Co, is a pan-tyrosine kinase inhibitor for the potential oral treatment of medullary thyroid cancer, glioblastoma multiforme and NSCLC. The prinicipal targets of XL-184 are MET, VEGFR-2 and RET, but the drug is also reported to display inhibitory activity against KIT, FLT3 and TEK. Preclinical studies demonstrated that XL-184 potently inhibited multiple receptor tyrosine kinases in various cancer cell lines and animal xenograft models, and that the drug exhibited significant oral bioavailability and blood-brain barrier penetration. A phase I clinical trial in patients with advanced solid malignancies indicated that XL-184 accumulated dose-dependently in the plasma and had a long terminal half-life. A phase II trial in patients with progressive or recurrent glioblastoma revealed modest but promising median progression-free survival. Toxicity and side effects for the drug have generally been of low-to-moderate severity. At the time of publication, three additional trials of XL-184 were recruiting patients, including a phase I trial in combination with standard of care in patients with glioblastoma, a phase I/II trial in combination with erlotinib in patients with NSCLC, and a phase III trial in patients with medullary thyroid cancer.

    Full Text Available Historically, the treatment algorithm applied to non small cell lung cancer (NSCLC was the same for all histologic subtypes. However, recent advances in our understanding of the molecular profiles of squamous and non-squamous NSCLC have changed this perspective. Histologic subtype and the presence of specific molecular abnormalities have predictive value for response to and toxicity from therapy, as well as overall survival. For patients with squamous NSCLC, a platinum agent plus gemcitabine, or paclitaxel is recommended as first-line therapy. The role of EGFR monoclonal antibodies is uncertain. Maintenance therapy is not widely recommended, although data exist for the use of erlotinib. The standard recommendation for second-line therapy is docetaxel and erlotinib should be considered as second or third-line therapy. There is ongoing research identifying molecular targets in squamous NSCLC and many agents are in early phase clinical trials. Immunotherapeutic approaches targeting programmed death 1 receptor (PD-1 and its ligand (PD-L1 appear promising.

Chemotherapy has reached a plateau in the overall survival curve of about 10 months. Therefore, in last decade novel targeted approaches have been developed to extend survival of these patients, including antiangiogenic treatment. Vascular endothelial growth factor (VEGF signaling pathway plays a dominant role in stimulating angiogenesis, which is the main process promoting tumor growth and metastasis. Bevacizumab (bev; Avastin® is a recombinant humanized monoclonal antibody that neutralizes VEGF’s biologic activity through a steric blocking of its binding with VEGF receptor. Currently, bev is the only antiangiogenic agent approved for the first-line treatment of advanced or recurrent nonsquamous NSCLC in “bev-eligible” patients. The ineligibility to receive bev is related to its toxicity. In the pivotal trials of bev in NSCLC, fatal bleeding events including pulmonary hemorrhage were observed with rates higher in the chemotherapy-plus-bev group. Therefore, in order to reduce the incidence of severe pulmonary hemorrhage, numerous exclusion criteria have been characteristically applied for bev such as central tumor localization or tumor cavitation, use of anticoagulant therapy, presence of brain metastases, age of patients (elderly. Subsequent studies designed to evaluate the safety of bev have demonstrated that this agent is safe and

    Full Text Available NPRL2, one of the tumor suppressor genes residing in a 120-kb homozygous deletion region of human chromosome band 3p21.3, has a high degree of amino acid sequence homology with the nitrogen permease regulator 2 (NPR2 yeast gene, and mutations of NPRL2 in yeast cells are associated with resistance to cisplatin-mediated cell killing. Previously, we showed that restoration of NPRL2 in NPRL2-negative and cisplatin-resistant cells resensitize lung cancer cells to cisplatin treatment in vitro and in vivo. In this study, we show that sensitization of non-small cell lung cancer (NSCLC cells to cisplatin by NPRL2 is accomplished through the regulation of key components in the DNA-damage checkpoint pathway. NPRL2 can phosphorylate ataxia telangiectasia mutated (ATM kinase activated by cisplatin and promote downstream gamma-H2AX formation in vitro and in vivo, which occurs during apoptosis concurrently with the initial appearance of high-molecular-weight DNA fragments. Moreover, this combination treatment results in higher Chk1 and Chk2 kinase activity than does treatment with cisplatin alone and can activate Chk2 in pleural metastases tumor xenograft in mice. Activated Chk1 and Chk2 increase the expression of cell cycle checkpoint proteins, including Cdc25A and Cdc25C, leading to higher levels of G2/M arrest in tumor cells treated with NPRL2 and cisplatin than in tumor cells treated with cisplatin only. Our results therefore suggest that ectopic expression of NPRL2 activates the DNA damage checkpoint pathway in cisplatin-resistant and NPRL2-negative cells; hence, the combination of NPRL2 and cisplatin can resensitize cisplatin nonresponders to cisplatin treatment through the activation of the DNA damage checkpoint pathway, leading to cell arrest in the G2/M phase and induction of apoptosis. The direct implication of this study is that combination treatment with NPRL2 and cisplatin may overcome cisplatin resistance and enhance therapeutic efficacy.

    Thymidylate synthase (TS) is a key enzyme responsible for DNA synthesis and repair. Altered expression of TS protein or TS gene polymorphisms has been associated with cancer progression and treatment response. This study investigated the expressions of TS and its gene SNPs in non-small cell lung cancer (NSCLC), and then its association with sensitivity to pemetrexed treatment. Immunohistochemistry and qRT-PCR were performed on 160 resected NSCLC specimens and corresponding normal tissues to assess the expressions of TS protein and TS mRNA, and for associations with clinicopathological data. Blood samples of 106 lung adenocarcinoma patients were examined for polymorphisms of the TS gene 3'-UTR 1494del 6 bp, which was then investigated for associations with responses of the patients to pemetrexed treatment and survival. Expression of both TS protein and its mRNA was elevated in NSCLC tissues compared with matched normal tissues, and significantly higher in lung squamous cell carcinoma than in lung adenocarcinoma. TS expression was associated with poor tumor differentiation. Furthermore, the genotyping data showed that 56% of lung adenocarcinoma patients had the TS gene 3'-UTR 1494 bp (-6 bp/-6 bp) genotype and the rest had TS gene 3'-UTR 1494 bp (-6 bp/+6 bp). There was no TS 3'-UTR 1494 bp (+6 bp/+6 bp) genotype in any patients. Statistical analysis revealed that gender, tumor stage, and TS 3'-UTR 1494del 6 bp polymorphism were significant prognostic factors after short-term pemetrexed treatment. Log-rank analysis revealed that patients with the (-6 bp/-6 bp) genotype had significantly better progression-free and overall survival than patients with (-6 bp/+6 bp). This study showed that TS protein is highly expressed in NSCLC and that polymorphisms of TS 3'-UTR 1494del 6 bp are associated with sensitivity of lung adenocarcinoma patients to pemetrexed treatment. This suggests that TS gene polymorphisms should be further evaluated as prognostic markers for personalized

    This single arm, phase II study aims to evaluate the role of epidermal growth factor receptor-tyrosine-kinase inhibitor erlotinib as maintenance therapy following concurrent chemoradiotherapy (cCRT) in unresectable locally advanced non-small-cell lung cancer (NSCLC). Patients with unresectable stage IIIA o dry IIIB NSCLC with no evidence of tumor progression after receiving a standard cCRT regimen with curative intent were included. Oral erlotinib 150 mg/day was administered within 4-6 weeks after the end of the cCRT for a maximum of 6 months if no disease progression or intolerable toxicity occurred. Primary end point was the progression-free rate (PFR) at 6 months. Secondary end points included time to progression (TTP) and overall survival (OS). Sixty-six patients were enrolled and received maintenance treatment with erlotinib [average: 4.5 months (95 % CI 4.0-5.0)]. PFR at 6 months was 63.5 % (41/66). With a median follow-up of 22.7 months (95 % CI 13.5-37.1), the median TTP was 9.9 months (95 % CI 6.2-12.1), and the median OS was 24.0 months (95 % CI 17.3-48.6). Most common adverse events (AEs) related to erlotinib were rash (78.8 %; 16.7 % grade 3), diarrhea (28.8 %; 1.5 % grade 3), fatigue (15.2 %; 1.5 % grade 3), anorexia (7.6 %; 1.5 % grade 3) and vomiting (4.6 %; none grade 3). Five patients (7.6 %) were withdrawn due to AEs. Erlotinib as maintenance therapy is an active treatment after cCRT in unselected patients with stage III NSCLC, reaching a 6-month PFR of 63.5 % and a median OS of 24 months. The safety profile of maintenance erlotinib was as expected and manageable.

The majority of NSCLC patients present with advanced, unresectable disease, which remains incurable. In advanced disease, chemotherapy with platinum (cisplatin or carboplatin in combination with a third-generation cytotoxic drug (vinorelbine, gemcitabine, paclitaxel, or docetaxel can provide a modest improvement in survival without impairing quality of life. In chemotherapy-naïve, advanced, non-squamous NSCLC patients, the combination of bevacizumab with chemotherapy was shown to produce better outcomes than chemotherapy alone. Response rates of 20%–40% can now be expected, with a median survival of 8–11 months and a 1-year survival rate of 30%–40%. In second-line treatment, docetaxel has shown superiority to best supportive care in terms of survival and quality of life. A pooled analysis comparing docetaxel administered weekly versus 3-weekly found similar survival rates between the schedules and a non-significant reduction in febrile neutropenia for the weekly regimen. Pemetrexed, a multitargeted antifolate agent, has shown clear activity in several tumors, including mesothelioma and NSCLC. In a phase III trial, second-line treatment with pemetrexed demonstrated overall survival comparable to docetaxel, with a more manageable toxicity profile.Keywords: pemetrexed, second-line therapy, NSCLC

    Diabetes has been consistently linked to many forms of cancers, such as liver, colorectal, pancreatic, and breast cancer, however, the role of diabetes in outcome among cancer patients remains unclear. In this study, we retrospectively reviewed electronic medical records of 342 inpatients newly diagnosed with NSCLC referred by a teaching hospital cancer center in southern Taiwan between 2005 and 2007 to examine the effects of fasting glucose levels at time of cancer diagnosis on overall survival in patients with non-small cell lung cancer (NSCLC). All patients were followed up until the end of 2010. The Kaplan-Meier method was used to compare survival curves for patients with and without diabetes. The Cox proportional hazards model was used to estimate hazard ratios for the association between diabetes, other prognostic factors and patient survival. We observed that significant prognostic factors for poor overall survival in patients with NSCLC included older age, smoking, poor performance status, advanced stage (stage IIIB or IV), and no cancer-directed surgery treatment. Particularly, we identified that diabetic state defined by fasting blood glucose level ≥126 mg/dl was another independent prognostic factor for these patients. Compared with those who had normal range of fasting glucose level (70-99 mg/dl), patients with high fasting glucose level (≥126 mg/dl) had 69% excess risk of all-cause mortality in patients with NSCLC. Diabetes as indicated by elevated fasting blood glucose was independently associated with a significantly higher risk of all-cause mortality in patients with NSCLC, indicating that diabetes or hyperglycemia effectively controlled may present an opportunity for improving prognosis in NSCLS patients with abnormal glucose level.

    Over recent years, [18F]-fluorodeoxyglucose positron emission tomography acquired together with low dose computed tomography (FDG-PET/CT) has proven its role as a staging modality in patients with non-small cell lung cancer (NSCLC). The purpose of this review was to present the evidence to use FDG-PET/CT for response evaluation in patients with NSCLC, treated with epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKI). All published articles from 1 November 2003 to 1 November 2013 reporting on 18F-FDG-PET response evaluation during EGFR-TKI treatment in patients with NSCLC were collected. In total 7 studies, including data of 210 patients were eligible for analyses. Our report shows that FDG-PET/CT response during EGFR-TKI therapy has potential in targeted treatment for NSCLC. FDG-PET/CT response is associated with clinical and radiologic response and with survival. Furthermore FDG-PET/CT response monitoring can be performed as early as 1-2 wk after initiation of EGFR-TKI treatment. Patients with substantial decrease of metabolic activity during EGFR-TKI treatment will probably benefit from continued treatment. If metabolic response does not occur within the first weeks of EGFR-TKI treatment, patients may be spared (further) unnecessary toxicity of ineffective treatment. Refining FDG-PET response criteria may help the clinician to decide on continuation or discontinuation of targeted treatment.

Inhibition of the Na/K-ATPase enzyme by ouabain disturbs the intracellular ion composition of cancer cells, altering cellular homeostasis. This suggests that inhibition of the Na/K pump results in cellular sensitization of malignant but not benign cells to the induction of apoptosis. Epidemiologic studies have also shown beneficial effects of digitalis in breast cancer incidence. At ASCO (American Society of Clinical Oncology 2007 our group presented a Phase II study showing encouraging results by adding digoxin to biochemotherapy for melanoma. Erlotinib is one of the standard second-line treatments for nonsmall cell lung cancer (NSCLC, with a response rate (RR of 10%. This study's hypothesis was that adding digoxin to erlotinib will improve the RR and time to progression (TTP in NSCLC.Methods: Patients with progressive disease (PD after chemotherapy were enrolled if they had an ECOG (Eastern Cooperative Oncology Group score from 0 to 2 and good organ function. Daily erlotinib 150 mg and digoxin 0.25 mg were taken by mouth. The digoxin dose was adjusted to keep levels between 1 and 2 ng/mL. Computed tomography scans were done every 6 weeks. Treatment continued until PD or significant toxicity occurred.Results: Patient accrual lasted from March 2006 until August 2008 and was stopped early at the time of interim analysis. Twenty-eight patients were enrolled, and 24 who completed at least 6 weeks of therapy are presented here. All patients had unresectable NSCLC stage III/IV at diagnosis. Median age was 61 (34–78, 14 were female, 17 had prior radiation (not involving the target lesions, 23 had one prior chemotherapy, and one subject had two. Only one patient was a never-smoker.

    1,25-dihydroxyvitamin D{sub 3} (1,25(OH){sub 2}D{sub 3}) exerts anti-proliferative activity by binding to the vitamin D receptor (VDR) and regulating gene expression. We previously reported that non-small cell lung cancer (NSCLC) cells which harbor epidermal growth factor receptor (EGFR) mutations display elevated VDR expression (VDR{sup high}) and are vitamin D-sensitive. Conversely, those with K-ras mutations are VDR{sup low} and vitamin D-refractory. Because EGFR mutations are found predominately in NSCLC cells with an epithelial phenotype and K-ras mutations are more common in cells with a mesenchymal phenotype, we investigated the relationship between vitamin D signaling capacity and the epithelial mesenchymal transition (EMT). Using NSCLC cell lines and publically available lung cancer cell line microarray data, we identified a relationship between VDR expression, 1,25(OH){sub 2}D{sub 3} sensitivity, and EMT phenotype. Further, we discovered that 1,25(OH){sub 2}D{sub 3} induces E-cadherin and decreases EMT-related molecules SNAIL, ZEB1, and vimentin in NSCLC cells. 1,25(OH){sub 2}D{sub 3}-mediated changes in gene expression are associated with a significant decrease in cell migration and maintenance of epithelial morphology. These data indicate that 1,25(OH){sub 2}D{sub 3} opposes EMT in NSCLC cells. Because EMT is associated with increased migration, invasion, and chemoresistance, our data imply that 1,25(OH){sub 2}D{sub 3} may prevent lung cancer progression in a molecularly defined subset of NSCLC patients.

    Erlotinib is an approved treatment for NSCLC locally advanced or with metastases, after failure of initial chemotherapy. The authors present a NSCLC clinical case of great clinical and imaging improvement, with no drug-induced toxicity observed, after treatment with erlotinib. A 76-year-old woman, never-smoker, had been diagnosed for lung adenocarcinoma, through thoracoscopy, after presenting a large-volume pleural effusion. At the time of diagnosis it was inoperable (stage IIIB - T4 N1 M0). She was submitted to two consecutive chemotherapy treatments with carboplatin+gemcitabin and pemetrexed, respectively. Due to its failure, with lack of response, erlotinib was set as the alternative choice, with great clinical and imaging improvement after 6 months of treatment. The authors recommend, even in the absence of EGFR result, the use of erlotinib when progression of the disease is seen, after initial chemotherapy, especially in lung adenocarcinoma and in never-smokers.

    Lung cancer (LC) is still the most common cause of cancer related deaths worldwide. Non-small cell lung cancer (NSCLC) accounts for 85% of all LC cases but is not a single entity. It is now accepted that, apart from the characteristic driver mutations, the unique molecular signatures of adeno- (AC) and squamous cell carcinomas (SCC), the two most common NSCLC subtypes should be taken into consideration for their management. Therapeutic interventions, however, frequently lead to chemotherapy resistance highlighting the need for in-depth analysis of regulatory mechanisms of multidrug resistance to increase therapeutic efficiency. Non-canonical Wnt5a and canonical Wnt7b and ABC transporter expressions were tested in primary human LC (n = 90) resections of AC and SCC. To investigate drug transporter activity, a three dimensional (3D) human lung aggregate tissue model was set up using differentiated primary human lung cell types. Following modification of the canonical, beta-catenin dependent Wnt pathway or treatment with cisplatin, drug transporter analysis was performed at mRNA, protein and functional level using qRT-PCR, immunohistochemistry, immune-fluorescent staining and transport function analysis. Non-canonical Wnt5a is significantly up-regulated in SCC samples making the microenvironment different from AC, where the beta-catenin dependent Wnt7b is more prominent. In primary cancer tissues ABCB1 and ABCG2 expression levels were different in the two NSCLC subtypes. Non-canonical rhWnt5a induced down-regulation of both ABCB1 and ABCG2 transporters in the primary human lung aggregate tissue model recreating the SCC-like transporter pattern. Inhibition of the beta-catenin or canonical Wnt pathway resulted in similar down-regulation of both ABC transporter expression and function. In contrast, cisplatin, the frequently used adjuvant chemotherapeutic agent, activated beta-catenin dependent signaling that lead to up-regulation of both ABCB1 and ABCG2 transporter

    Full Text Available Tyrosine kinase inhibitors (TKIs against the epidermal growth factor receptor (EGFR are the standard of care treatment in non-small cell lung cancer (NSCLC. TKIs are used first line in EGFR mutation-positive NSCLC; erlotinib is the only TKI approved for subsequent lines of treatment in EGFR wild-type NSCLC. As promising as TKIs are in helping patients avoid some of the side effects of traditional cytotoxic chemotherapy, they do come with a variety of side effects.This article will describe the most common adverse events associated with the epidermal EGFR family of TKIs including diarrhea, rash, mucositis, and paronychia. The objective of this paper is to provide simple guidelines to assist oncologists in managing these common toxicities. As patient survival is often directly correlated with successful therapeutic drug delivery, the management of TKI- induced adverse events ensures proper treatment and may avoid discontinuation or reduction of the therapeutic.

    Full Text Available Non-small cell lung cancer (NSCLC is one of most common malignancies and the leading cause of cancer deaths worldwide. Despite advances in targeted therapies, majority of NSCLC patients do not have targetable genomic alterations. Nevertheless, recent discovery that NSCLC is an immunogenic tumor type, and several breakthroughs in immunotherapies have led to rapid expansion of this new treatment modality in NSCLC with recent FDA approvals of PD-1 inhibitors, nivolumab and pembrolizumab. Here, we review promising immunotherapeutic approaches in metastatic NSCLC, including checkpoint inhibitors, agents with other mechanisms of action, and immunotherapy combinations with other drugs. With advent of immunotherapy, therapeutic options in metastatic NSCLC are rapidly expanding with the hope to further expand life expectancy in metastatic lung cancer.

    To develop a fully automated procedure for multicriterial volumetric modulated arc therapy (VMAT) treatment planning (autoVMAT) for stage III/IV non-small cell lung cancer (NSCLC) patients treated with curative intent. After configuring the developed autoVMAT system for NSCLC, autoVMAT plans were compared with manually generated clinically delivered intensity-modulated radiotherapy (IMRT) plans for 41 patients. AutoVMAT plans were also compared to manually generated VMAT plans in the absence of time pressure. For 16 patients with reduced planning target volume (PTV) dose prescription in the clinical IMRT plan (to avoid violation of organs at risk tolerances), the potential for dose escalation with autoVMAT was explored. Two physicians evaluated 35/41 autoVMAT plans (85%) as clinically acceptable. Compared to the manually generated IMRT plans, autoVMAT plans showed statistically significant improved PTV coverage (V{sub 95%} increased by 1.1% ± 1.1%), higher dose conformity (R{sub 50} reduced by 12.2% ± 12.7%), and reduced mean lung, heart, and esophagus doses (reductions of 0.9 Gy ± 1.0 Gy, 1.5 Gy ± 1.8 Gy, 3.6 Gy ± 2.8 Gy, respectively, all p < 0.001). To render the six remaining autoVMAT plans clinically acceptable, a dosimetrist needed less than 10 min hands-on time for fine-tuning. AutoVMAT plans were also considered equivalent or better than manually optimized VMAT plans. For 6/16 patients, autoVMAT allowed tumor dose escalation of 5-10 Gy. Clinically deliverable, high-quality autoVMAT plans can be generated fully automatically for the vast majority of advanced-stage NSCLC patients. For a subset of patients, autoVMAT allowed for tumor dose escalation. (orig.)

Crizotinib was the first ALK tyrosine kinase inhibitor to receive fast approval and is currently indicated as the first-line therapy for advanced, ALK-positive NSCLC patients. However, despite crizotinib’s efficacy, patients almost invariably progress, with the central nervous system being one of the most common sites of relapse. Different mechanisms of acquired resistance have been identified, including secondary ALK mutations, ALK copy number alterations and activation of bypass tracks. Different highly potent and brain-penetrant next-generation ALK inhibitors have been developed and tested in NSCLC patients with ALK rearrangements. Ceritinib, a structurally distinct and selective ALK inhibitor, showed 20 times higher potency than crizotinib in

    For many decades, the use of chemotherapy as second-line therapy in non-small-cell lung cancer relied upon disease progression. Several studies have shown that four to six cycles of chemotherapy administered as front-line therapy treatment offers a survival advantage to patients; however, further chemotherapy beyond this initial treatment was more associated with side effects and no benefit in survival. Until 2009, second-line treatment for lung cancer was well established for three therapeutic agents: docetaxel, pemetrexed and erlotinib. Currently, the timeframe to use these agents has been challenged by two large randomized clinical trials in which pemetrexed (JMEN trial) and erlotinib (Sequential Tarceva in Unresectable NSCLC [SATURN] trial) were used as 'maintenance' therapy and shown to impact progression-free survival and overall survival. This review focuses on the actual dilemma that medical oncologists face in clinical practice in terms of when and to whom maintenance therapy should be applied or if the 'watch and wait' approach prior to start second-line therapy is still advisable.

    This study aimed to assess the incidence of mutations in the epidermal growth factor receptor (EGFR) gene in non-small-cell lung cancer (NSCLC) patients in the Galician region of Spain and the clinical management and outcome of patients carrying EGFR mutations. All newly diagnosed advanced or metastatic NSCLC patients were screened for EGFR mutations in matched tumor samples (tissue or cytology specimens) and serum samples. Of 198 patients screened for EGFR mutations in tumor samples, 184 had evaluable data and, of these, 25 (13.6%) had EGFR mutations (84% sensitizing mutations). EGFR mutation was found in serum in 14 (8.1%) patients (of 174 evaluable). Compared to matched tumor tissue, serum EGFR mutation testing specificity and sensitivity were 99% and 52%, respectively. All but two patients received gefitinib. Median progression-free survival and overall survival were 10 (95% confidence interval: 4.8-15.3) months and 17.8 (95% confidence interval: 13.9-21.6) months, respectively, in patients carrying sensitizing mutations. The incidence of EGFR mutations in Galicia is consistent with previous data in Spain. Our results also support the feasibility of EGFR testing to guide treatment decision making using tumor tissue or cytology samples, or serum samples if tumor specimens are unavailable. These findings also confirm that first-line gefitinib is an active treatment option in Caucasians with EGFR mutation-positive NSCLC.

    The goal of radiation therapy for non-small cell lung cancer (NSCLC) is to improve the survival rate of patients without increasing treatment-related toxicity and to improve patients' quality of life. Several prospective randomized trials have demonstrated a survival advantage in combined modality treatment over radiotherapy or chemotherapy alone when a cisplatin-based chemotherapy regimen is utilized in the treatment plan. Combined modality treatment of cisplatin-based chemotherapy and radiotherapy is standard treatment for selected patients such as those with better performance status with locally or regionally advanced lung cancer including T3-T4 or N2-N3. Determining the contribution of new agents in combined modality treatment will require carefully designed and conducted clinical trials. High-dose involved field radiation therapy using 3D-conformal radiation therapy potentially enables the use of higher doses than standard radiation therapy, because less normal tissue is irradiated, and may improve local control and survival. The combination of radiotherapy with chemotherapy and dose escalation using 3D-conformal radiation therapy is also a possibility in unresectable NSCLC. In surgery cases, the results of several Phase III trials of cisplatin-based preoperative chemotherapy have suggested survival improvement. But the concept needs to be tested in a larger Phase III trial. (author)

    Testing for genetic abnormalities in epithelial growth factor receptor (EGFR), anaplastic lymphoma receptor tyrosine kinase (ALK), and potentially additional genes is a critical tool in the care of advanced NSCLC. There is conflicting evidence for the role of such tests in early NSCLC. We report a single-institute Sequenom testing for a wide range of mutations and their clinical correlations in early-resected NSCLC specimens. Early NSCLC paraffin-embedded, formalin-fixed (FFPE) specimens were collected, DNA extracted, and using Sequenom-based matrix-assisted laser desorption/ionization-time of flight analysis, mutations in 22 oncogenes and tumor suppressor genes were evaluated. Clinical data was collected retrospectively. The technique was found to be feasible. Thirty-six of 96 patients (37.5%) had any genetic abnormality identified, and 8 (8.3%) had 2 or more mutations. Kirsten rat sarcoma viral oncogene homolog (KRAS) and EGFR were the most common genes to appear mutated (15.6%); phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA) was the gene to be found most commonly in tumors with co-mutations. Transversions were found mostly in KRAS gene mutations and to be nonprognostic. No difference in the spectrum of mutations was found between squamous-cell and non-squamous-cell lung cancers. Ever-smokers showed a trend for worse prognosis, with a similar spectrum of mutations. Sequenom-based mutation screen is feasible using FFPE samples. More than a third of the patients were found to harbor some genetic abnormality, and 8% were found to have more than a single mutated gene. Wide-range gene screens using large sample depositories are required for further insight into the important genes at play in early NSCLC. Copyright © 2014 Elsevier Inc. All rights reserved.

  17. Sulforaphane attenuates EGFR signaling in NSCLC cells.

    EGFR, a receptor tyrosine kinase (RTK), is frequently overexpressed and mutated in non-small cell lung cancer (NSCLC). Tyrosine kinase inhibitors (TKIs) have been widely used in the treatment of many cancers, including NSCLC. However, intrinsic and acquired resistance to TKI remains a common obstacle. One strategy that may help overcome EGFR-TKI resistance is to target EGFR for degradation. As EGFR is a client protein of heat-shock protein 90 (HSP90) and sulforaphane is known to functionally regulate HSP90, we hypothesized that sulforaphane could attenuate EGFR-related signaling and potentially be used to treat NSCLC. Our study revealed that sulforaphane displayed antitumor activity against NSCLC cells both in vitro and in vivo. The sensitivity of NSCLC cells to sulforaphane appeared to positively correlate with the inhibition of EGFR-related signaling, which was attributed to the increased proteasomal degradation of EGFR. Combined treatment of NSCLC cells with sulforaphane plus another HSP90 inhibitor (17-AAG) enhanced the inhibition of EGFR-related signaling both in vitro and in vivo. We have shown that sulforaphane is a novel inhibitory modulator of EGFR expression and is effective in inhibiting the tumor growth of EGFR-TKI-resistant NSCLC cells. Our findings suggest that sulforaphane should be further explored for its potential clinical applications against NSCLC.

    Immune checkpoint inhibitors (ICIs) have been incorporated in the treatment strategy of advanced non-small cell lung cancer (NSCLC). Beyond the already approved indications in first- and second-line setting of advanced NSCLC, new data has recently emerged demonstrating its efficacy in locally advanced disease as maintenance after chemo-radiotherapy and currently several trials are also exploring its efficacy in earlier stages of the disease to evaluate whether these results could be extrapolated to the adjuvant setting. With the advent of all these new therapies, their potential in other thoracic malignancies such as mesothelioma and small-cell lung cancer are also being evaluated with encouraging preliminary data that endorses their short-term incorporation as new therapeutic options in these thoracic malignancies. However, despite all these new evidence, there are still several open questions that remain to be solved like the use of immune agents in special subpopulations such as elderly or fragile patients or the case of patients with brain metastases or autoimmune disorders. In addition some other open questions remain with regards ICIs activity in patients receiving corticosteroid or antibiotics, the potential use in oncogenic addicted tumours, as well as the safety of retreatment after the onset of immune-related adverse events (ir-AE) or the optimal dose schedule or time on treatment for ICIs administration. Herein, we propose to address all these questions, reviewing most recent evidence available in order to give readers some practical advises and guidance on how to deal with these challenges when treating NSCLC patients with immunotherapy.

    2014-10-01

    Full Text Available Radiotherapy has had important role in the palliation of NSCLC. Randomized trials tend to suggest that, in general, short regimens give similar palliation and toxicity compared to longer regimens. The benefit of combining chemotherapy to radiosensitize the palliative radiation treatment is an open question, but so far it has not been proved to be very useful in NSCLC. The addition of molecular targeted drugs to radiotherapy outside of approved regimens or clinical trials warrants careful consideration for every single case and probably should not be used as a routine management.Stereotactic radiosurgery (SRS and stereotactic body radiation therapy (SBRT are modern techniques being used each time more frequently in the treatment of single or oligometastases. In general, they offer good tumour control with little toxicity (with a more expensive cost compared to the traditionally fractionated radiotherapy regimens.

    Full Text Available Heat shock protein 70 (Hsp70 is frequently overexpressed in tumor cells. An unusual cell surface localization could be demonstrated on a large variety of solid tumors including lung, colorectal, breast, squamous cell carcinomas of the head and neck, prostate and pancreatic carcinomas, glioblastomas, sarcomas and hematological malignancies, but not on corresponding normal tissues. A membrane (mHsp70-positive phenotype can be determined either directly on single cell suspensions of tumor biopsies by flow cytometry using cmHsp70.1 monoclonal antibody or indirectly in the serum of patients using a novel lipHsp70 ELISA. A mHsp70-positive tumor phenotype has been associated with highly aggressive tumors, causing invasion and metastases and resistance to cell death. However, natural killer (NK, but not T cells were found to kill mHsp70-positive tumor cells after activation with a naturally occurring Hsp70 peptide (TKD plus low dose IL-2 (TKD/IL-2. Safety and tolerability of ex vivo TKD/IL-2 stimulated, autologous NK cells has been demonstrated in patients with metastasized colorectal and NSCLC in a phase I clinical trial. Based on promising clinical results of the previous study, a phase II randomized clinical study was initiated in 2015. The primary objective of this multicenter proof-of-concept trial is to examine whether an adjuvant treatment of NSCLC patients after platinum based radiochemotherapy with TKD/IL-2 activated, autologous NK cells is clinically effective. As a mHsp70-positive tumor phenotype is associated with poor clinical outcome only mHsp70-positive tumor patients will be recruited into the trial. The primary endpoint of this study will be the comparison of the progression-free survival of patients treated with ex vivo activated NK cells compared to patients who were treated with radiochemotherapy alone. As secondary endpoints overall survival, toxicity, quality-of-life and biological responses will be determined in both study groups.

    Full Text Available Abstract Background NSCLC exhibits considerable heterogeneity in its sensitivity to chemotherapy and similar heterogeneity is noted in vitro in a variety of model systems. This study has tested the hypothesis that the molecular basis of the observed in vitro chemosensitivity of NSCLC lies within the known resistance mechanisms inherent to these patients' tumors. Methods The chemosensitivity of a series of 49 NSCLC tumors was assessed using the ATP-based tumor chemosensitivity assay (ATP-TCA and compared with quantitative expression of resistance genes measured by RT-PCR in a Taqman Array™ following extraction of RNA from formalin-fixed paraffin-embedded (FFPE tissue. Results There was considerable heterogeneity between tumors within the ATP-TCA, and while this showed no direct correlation with individual gene expression, there was strong correlation of multi-gene signatures for many of the single agents and combinations tested. For instance, docetaxel activity showed some dependence on the expression of drug pumps, while cisplatin activity showed some dependence on DNA repair enzyme expression. Activity of both drugs was influenced more strongly still by the expression of anti- and pro-apoptotic genes by the tumor for both docetaxel and cisplatin. The doublet combinations of cisplatin with gemcitabine and cisplatin with docetaxel showed gene expression signatures incorporating resistance mechanisms for both agents. Conclusion Genes predicted to be involved in known mechanisms drug sensitivity and resistance correlate well with in vitro chemosensitivity and may allow the definition of predictive signatures to guide individualized chemotherapy in lung cancer.

    The purpose of this article was to describe the process and results of the preliminary qualitative development of a new symptoms-based patient-reported outcome (PRO) measure intended for assessing treatment benefit in clinical trials of advanced non-small cell lung cancer (NSCLC). Individual qualitative interviews were conducted in adults with NSCLC (Stages I-IV) in the United States. Experienced interviewers conducted concept-elicitation (CE) and cognitive interviews using semistructured interview guides. The CE interview guide was used for eliciting spontaneous reports of symptom experiences along with probing to further explore and confirm concepts. Interview transcripts were coded and analyzed by professional qualitative coders, and were summarized by like content using an iterative coding framework. Data from the CE interviews were considered alongside existing literature and clinical expert opinion during an item-generation process, leading to the development of a preliminary version of the NSCLC Symptom Assessment Questionnaire (SAQ). Three waves of cognitive interviews were conducted to evaluate concept relevance, item interpretability, and structure of the draft items and to facilitate further instrument refinement. Fifty-one subjects (mean [SD] age, 64.9 [11.2] years; 51.0% women) participated in the CE interviews. A total of 1897 expressions of NSCLC-related symptoms were identified and coded in interview transcripts, representing ~42 distinct symptom concepts. A 9-item initial-draft instrument was developed for testing in 3 waves of cognitive interviews with additional subjects with NSCLC (n = 20), during which both paper and electronic versions of the instrument were evaluated and refined. Participant responses and feedback during cognitive interviews led to the removal of 2 items and substantial modifications to others. The NSCLC-SAQ is a 7-item PRO measure intended for use in advanced NSCLC clinical trials to support medical product labelling. The

    Four to six cycles of platinum-based chemotherapy are currently recommended for the first-line treatment of advanced non-small-cell lung cancer (NSCLC). Several studies have assessed the benefit of maintenance therapy following platinum-based first-line therapy, to improve disease control, and thus, progression-free and overall survival with minimal toxicity and maintenance or improvement of quality of life of patients. We review here clinical trials evaluating continuation maintenance therapy or switch maintenance therapy in locally advanced or metastatic NSCLC, to highlight the achievements made and critical issues faced. Based on the available results and limitations of these trials, maintenance therapy should be considered a good treatment strategy for a limited subgroup of patients. Maintenance therapy should be personalised according to the characteristics of patients and their disease, taking into account the data available for the agents used in this setting. © The Author 2013.

    Full Text Available Background and objective More and more chest physicians chose video-assisted thoracoscopic surgery (VATS to treat early stage non-small cell lung cancer (NSCLC. In recent years, there is still lack of a random trial comparing the clinical outcomes of VATS and stereotactic body radiotherapy (SBRT in treating NSCLC. To provide a reference for the choice between VATS and SBRT, in the current meta-analysis, we compared the clinical outcomes of these two therapies in treating NSCLC. Methods Five major medical databases, CNKI, CPVIP (http://www.cqvip.com/, PubMed, Embase, and ISI web of science were systematically searched to identify all studies from January 2010 to February 2016 on VATS and SBRT therapies. Finally, original English or Chinese publications of stage I and II NSCLC with adequate patients and adequate SBRT doses were enrolled. A multivariate random effects model was used to perform a meta-analysis to compare overall survival and disease free survival between VATS and SBRT while adjusting for median age and operable patient numbers. Results Fourteen VATS studies (included 3,482 patients and nineteen SBRT studies (included 3,997 patients published in the same period were eligible. The median age and follow-up duration were 64 years and 43.4 months for VATS patients and 74 years and 29.5 months for SBRT patients, respectively. The mean unadjusted overall survival rates at 1, 2, 3, and 5 years with VATS were 93.5%, 84.9%, 77.0% and 76.3% compared to 89.0% 73.3% 59.0% and 36.7% with SBRT. The mean unadjusted disease free survival rates at 1, 2, 3, and 5 years with VATS were 93.6%, 88.6%, 85.6% and 75.6% compared to 79.3%, 72.1%, 64.9% and 58.9% with SBRT. While, after adjusted for proportion of operable patients and median age, the estimate overall survival rates at 1, 2, 3, and 5 years with VATS were 94%, 92%, 84% and 71% compared to 98%, 95%, 87% and 83% with SBRT. And the estimate disease free survival rates at 1, 2, 3, and 5 years with

    Full Text Available Angiogenesis is a complex biological process that plays a relevant role in sustaining the microenvironment, growth, and metastatic potential of several tumors, including non-small cell lung cancer (NSCLC. Bevacizumab was the first angiogenesis inhibitor approved for the treatment of patients with advanced NSCLC in combination with chemotherapy; however, it was limited to patients with non-squamous histology and first-line setting. Approval was based on the results of two phase III trials (ECOG4599 and AVAIL that demonstrated an improvement of about two months in progression-free survival (PFS in both trials, and in the ECOG4599 trial, an improvement in overall survival (OS also. Afterwards, other antiangiogenic agents, including sunitinib, sorafenib, and vandetanib have been unsuccessfully tested in first and successive lines. Recently, two new antiangiogenic agents (ramucirumab and nintedanib produced a significant survival benefit in second-line setting. In the REVEL study, ramucirumab plus docetaxel prolonged the median OS of patients with any histology NSCLC when compared with docetaxel alone (10.4 versus 9.1 months, hazard ratio (HR 0.857, p = 0.0235. In the LUME-Lung 1 study, nintedanib plus docetaxel prolonged the median PFS of patients with any tumor histology (p = 0.0019, and improved OS (12.6 versus 10.3 months in patients with adenocarcinoma. As a result, it became a new option for the second-line treatment of patients with advanced NSCLC and adenocarcinoma histology. Identifying predictive biomarkers to optimize the benefit of antiangiogenic drugs remains an ongoing challenge.

  8. Examination of 12-lipoxygenase (12-LOX) as a therapeutic target in non-small cell lung cancer (NSCLC): Mechanisms controlling survival and induction of apoptosis following selective inhibition

    Cathcart, Mary Clare

    2011-06-01

    Background: Platelet-type 12-LOX is an arachidonic acid metabolising enzyme resulting in the formation of 12(S)-HETE, which stimulates tumour cell adhesion, invasion and metastasis. This study aimed to examine the expression profile and role of this enzyme in NSCLC, and determine if it is a potential target for intervention. Methods: A panel of retrospective resected lung tumours was stained for 12-LOX expression by IHC. Levels of the 12-LOX metabolite, 12(S)-HETE, were examined in 50 NSCLC serum samples, and correlated with serum VEGF. A panel of NSCLC cell lines were treated with baicalein (10 uM), a selective inhibitor of 12-LOX, or 12(S)-HETE (100 ng\\/ml) and cell survival\\/proliferation examined by BrdU. Apoptosis following 12-LOX inhibition was examined by HCS and validated by FACS and DNA laddering. The effect of 12-LOX inhibition on NSCLC tumour growth and survival was examined in-vivo using an athymic nude mouse model. Gene alterations following 12-LOX inhibition in NSCLC cell lines were assessed by qPCR arrays and validated by RT-PCR. Transient transfection methods were used to examine the effects of 12-LOX overexpression in NSCLC cells. Results: 12-LOX expression was observed to a varying degree in human lung cancers of varying histological subtypes. 12(S)-HETE levels were correlated (p<0.05) with those of VEGF. Baicalein inhibited proliferation\\/survival in all cell lines, while 12(S)-HETE increased proliferation. 12-LOX inhibition increased apoptosis, indicated by a reduction in f-actin content and mitochondrial mass potential. Treatment with baicalein significantly reduced the growth of NSCLC tumours and increased overall survival in athymic nude mice. qPCR array data implicated a number of apoptosis\\/angiogenesis genes regulating these effects, including bcl-2, VEGF, integrin A2 and A4. 12-LOX overexpression resulted in an increase in VEGF secretion, confirming qPCR observations. Conclusions: 12-LOX is a survival factor\\/potential target in

    Full Text Available Abstract Background To evaluate the performance of surface-based deformable image registration (DR for adaptive radiotherapy of non-small cell lung cancer (NSCLC. Methods Based on 13 patients with locally advanced NSCLC, CT images acquired at treatment planning, midway and the end of the radio- (n = 1 or radiochemotherapy (n = 12 course were used for evaluation of DR. All CT images were manually [gross tumor volume (GTV] and automatically [organs-at-risk (OAR lung, spinal cord, vertebral spine, trachea, aorta, outline] segmented. Contours were transformed into 3D meshes using the Pinnacle treatment planning system and corresponding mesh points defined control points for DR with interpolation within the structures. Using these deformation maps, follow-up CT images were transformed into the planning images and compared with the original planning CT images. Results A progressive tumor shrinkage was observed with median GTV volumes of 170 cm3 (range 42 cm3 - 353 cm3, 124 cm3 (19 cm3 - 325 cm3 and 100 cm3 (10 cm3 - 270 cm3 at treatment planning, mid-way and at the end of treatment. Without DR, correlation coefficients (CC were 0.76 ± 0.11 and 0.74 ± 0.10 for comparison of the planning CT and the CT images acquired mid-way and at the end of treatment, respectively; DR significantly improved the CC to 0.88 ± 0.03 and 0.86 ± 0.05 (p = 0.001, respectively. With manual landmark registration as reference, DR reduced uncertainties on the GTV surface from 11.8 mm ± 5.1 mm to 2.9 mm ± 1.2 mm. Regarding the carina and intrapulmonary vessel bifurcations, DR reduced uncertainties by about 40% with residual errors of 4 mm to 6 mm on average. Severe deformation artefacts were observed in patients with resolving atelectasis and pleural effusion, in one patient, where the tumor was located around large bronchi and separate segmentation of the GTV and OARs was not possible, and in one patient, where no clear shrinkage but more a decay of the tumor was observed

    The pathogenesis and progression of lung cancer is a complicated process in which many genes take part. But molecular gene testing is typically only performed in advanced-stage non-squamous non-small-cell lung cancer (NSCLC). The value of tyrosine kinase inhibitors (TKI) administration is not widely recognized with respect to early-stage NSCLC. Here, we present a case of a man, heavy smoker who initially presented with stage IA lung adenocarcinoma (LADC). Three years after a lung lobectomy, he was diagnosed with advanced lung squamous cell carcinoma (SCC), according to laboratory, imaging, and pathological examinations. The case initially had an early-stage LADC with an L858R epidermal growth factor receptor (EGFR) mutation. A subsequent advanced SCC bearing EGFR L858R/T790M mutations occurred 3 years after surgery. The comprehensive therapy we utilized, including surgical resection for the early-stage lesion and GP chemotherapy and local radiotherapy as the first line therapy along with gefitinib maintenance treatment for the advanced metachronous second primary tumors (MST). The synthetical therapy, have resulted in our patient with remaining alive and progression free for 4.5 years. This case suggests that changes in molecular pathology should be monitored closely throughout cancer progression to guide personalized therapy and improve prognosis. We further review administration of TKI to early-stage NSCLC and to the metachronous second primary tumors (MST) in survivors.

Of the less frequently described CAD antihistamines, astemizole showed a similar significant association with reduced mortality as loratadine among patients with any non-localized cancer, and ebastine use showed a similar tendency. The association between CAD antihistamine use and reduced mortality was stronger among patients with records of concurrent chemotherapy than among those without such records. In line with this, sub-micromolar concentrations of loratadine, astemizole and ebastine sensitized NSCLC cells to chemotherapy and reverted multidrug resistance in NSCLC, breast and prostate cancer cells. Thus, CAD antihistamines may improve the efficacy of cancer chemotherapy. Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.

Median progression-free survival and overall survival were 10 (95% confidence interval: 4.8–15.3 months and 17.8 (95% confidence interval: 13.9–21.6 months, respectively, in patients carrying sensitizing mutations. Conclusion: The incidence of EGFR mutations in Galicia is consistent with previous data in Spain. Our results also support the feasibility of EGFR testing to guide treatment decision making using tumor tissue or cytology samples, or serum samples if tumor specimens are unavailable. These findings also confirm that first-line gefitinib is an active treatment option in Caucasians with EGFR mutation-positive NSCLC.

    Full Text Available Objectives: Src family kinases (SFKs are expressed in NSCLC and may be involved in tumor growth and metastases. Inhibition of SFK may also enhance radiation. The purpose of this study was to evaluate if a maximum dose of 100 mg of dasatinib could be safely administered with concurrent chemoradiation and then continued as maintenance for patients with newly diagnosed stage III NSCLC.Methods: Patients with stage III locally advanced NSCLC received paclitaxel, 50mg/m2/week, with carboplatin area under the curve (AUC = 2, weekly for 7 weeks, and concurrent radiotherapy, 64.8 Gy. Three dose levels of dasatinib 50, 70 and 100mg/day were planned.Results: Eleven patients with locally advanced NSCLC were entered. At the 70 mg dose level 1 patient had grade 5 pneumonitis not responsive to therapy, and 1 patient had reversible grade 3 pneumonitis and grade 3 pericardial effusion. Due to these toxicities the Brown University Oncology Group Data Safety Monitoring Board terminated the study. Conclusion: Dasatinib could not be safely combined with concurrent chemoradiation for stage 3 lung cancer due to pneumonitis.

    In the present study we investigated the prognostic value of Circulating Tumour Cells (CTC) and their utility for therapy monitoring in non-small cell lung cancer (NSCLC). A total of 43 patients newly diagnosed with NSCLC were prospectively enrolled. Blood samples were obtained before the 1st, 2nd and 5th cycles of chemotherapy and analyzed using CellSearch technology. Both CTC and CTC-related objects (not morphological standard or broken epithelial cells) were counted. At baseline 18 (41.9%) patients were positive for intact CTC count and 10 (23.2%) of them had ≥5 CTC, while CK positive events were found in 79.1% of patients. The group of patients with CTC ≥5 at baseline presented worse PFS and OS than those with <5 CTC (p = 0.034 and p = 0.008, respectively). Additionally, high levels of total CK positive events were associated with poor prognosis in the group of patients with <5 CTC. Regarding therapy monitoring, patients presenting increased levels of CTC during the treatment demonstrated lower OS and PFS rates. All these data supported the value of CTC as a prognostic biomarker and as a surrogate indicator of chemotherapy effectiveness in advanced NSCLC patients, with the additional value of analyzing other “objects” such as apoptotic CTC or CK fragments to guide the clinical management of these patients.

    The demand for early-response evaluation with 2'-deoxy-2'-[18F] fluoro-D-glucose (F-18-FDG) positron emission tomography combined with whole body CT (PET/CT) is rapidly growing. This study was initiated to evaluate the applicability of the PET response criteria in solid tumours (PERCIST 1.0) for response evaluation. We performed a retrospective study of 21 patients with locally advanced non-small cell lung cancer (NSCLC), who had undergone both a baseline and a follow-up F-18-FDG-PET/CT scan during their treatments. The scans were performed at our institution in the period September 2009 and March 2011 and were analysed visually and according to PERCIST 1.0 by one board-certified nuclear medicine physician. The response was compared with overall survival (OS) and progression-free survival (PFS). The variation in key parameters affecting the F-18-FDG uptake was assessed. A kappa of 0.94 corresponding to an almost perfect agreement was found for the comparison of the visual evaluation with PERCIST. Patients with partial metabolic response and stable metabolic disease (as evaluated by PERCIST 1.0) had statistically significant longer median time to progression: 8.4 months (confidence interval (CI) 5.1-11.8 months) as compared with 2.7 months (CI 0-5.6 months) in patients classified with progression. The variation in uptake time between baseline and follow-up scans was more than the recommended 15 min in 48% of patients. PERCIST 1.0 is readily implementable and highly comparable with visual evaluation of response using early F-18-FDG-PET/CT scanning for locally advanced NSCLC patients. In spite of variations in parameters affecting F-18-FDG uptake, evaluation of F-18-FDG-PET/CT during treatment with PERCIST 1.0 is shown to separate non-responders from responders, each with statistically significant differences in both OS and PFS. © 2015 The Royal Australian and New Zealand College of Radiologists.

    Full Text Available Abstract Background Lung cancer is the leading cause of cancer-related death worldwide. Genetic and epigenetic alterations have been identified frequently in lung cancer, such as promoter methylation, gene mutations and genomic amplification. However, the interaction between genetic and epigenetic events and their significance in lung tumorigenesis remains poorly understood. Methods We determined the promoter methylation of 6 genes and PIK3CA amplification using quantitative methylation-specific PCR (Q-MSP and real-time quantitative PCR, respectively, and explore the association of promoter methylation with PIK3CA amplification in a large cohort of clinically well-characterized non-small cell lung cancer (NSCLC. Results Highly frequent promoter methylation was observed in NSCLC. With 100% diagnostic specificity, excellent sensitivity, ranging from 45.8 to 84.1%, was found for each of the 6 genes. The promoter methylation was associated with histologic type. Methylation of CALCA, CDH1, DAPK1, and EVX2 was more common in squamous cell carcinomas (SCC compared to adenocarcinomas (ADC. Conversely, there was a trend toward a higher frequency of RASSF1A methylation in ADC than SCC. In addition, PIK3CA amplification was frequently found in NSCLC, and was associated with certain clinicopathologic features, such as smoking history, histologic type and pleural indentation. Importantly, aberrant promoter methylation of certain genes was significantly associated with PIK3CA amplification. Conclusions Our data showed highly frequent promoter methylation and PIK3CA amplification in Chinese NSCLC population, and first demonstrated the associations of gene methylation with PIK3CA amplification, suggesting that these epigenetic events may be a consequence of overactivation of PI3K/Akt pathway.

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

    To investigate potential associations between dose to heart (sub)structures and non-cancer death, in early stage non-small cell lung cancer (NSCLC) patients treated with stereotactic body radiation therapy (SBRT). 803 patients with early stage NSCLC received SBRT with predominant schedules of 3×18Gy (59%) or 4×12Gy (19%). All patients were registered to an average anatomy, their planned dose deformed accordingly, and dosimetric parameters for heart substructures were obtained. Multivariate Cox regression and a sensitivity analysis were used to identify doses to heart substructures or heart region with a significant association with non-cancer death respectively. Median follow-up was 34.8months. Two year Kaplan-Meier overall survival rate was 67%. Of the deceased patients, 26.8% died of cancer. Multivariate analysis showed that the maximum dose on the left atrium (median 6.5Gy EQD2, range=0.009-197, HR=1.005, p-value=0.035), and the dose to 90% of the superior vena cava (median 0.59Gy EQD2, range=0.003-70, HR=1.025, p-value=0.008) were significantly associated with non-cancer death. Sensitivity analysis identified the upper region of the heart (atria+vessels) to be significantly associated with non-cancer death. Doses to mainly the upper region of the heart were significantly associated with non-cancer death. Consequently, dose sparing in particular of the upper region of the heart could potentially improve outcome, and should be further studied. Copyright © 2017 Elsevier B.V. All rights reserved.

    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. 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). 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. 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.

    This study investigated the potential prognostic value of the number of involved extracranial organs in patients with brain metastasis from non-small cell lung cancer (NSCLC). A total of 472 patients who received whole-brain radiotherapy (WBRT) alone with 5 x 4 Gy or 10 x 3 Gy for brain metastasis from NSCLC were included in this retrospective study. In addition to the number of involved extracranial organs, 6 further potential prognostic factors were investigated including WBRT regimen, age, gender, Karnofsky Performance Score (KPS), number of brain metastases, and the interval from cancer diagnosis to WBRT. Subgroup analyses were performed for patients with metastatic involvement of one (lung vs. bone vs. other metastasis) and two (lung+bone vs. lung+lymph nodes vs. other combinations) extracranial organs. The survival rates at 6 months of the patients with involvement of 0, 1, 2, 3, and ≥4 extracranial organs were 52, 27, 17, 4, and 14%, respectively (p<0.001). On multivariate analysis, the number of involved extracranial organs remained significant (risk ratio 1.32; 95% confidence interval 1.19-1.46; p<0.001). Age <65 years (p=0.004), KPS ≥70 (p<0.001), and only 1-3 brain metastases (p=0.022) were also significantly associated with survival in the multivariate analysis. In the separate analyses of patients with involvement of one and two extracranial organs, survival was not significantly different based on the pattern of extracranial organ involvement. The number of involved extracranial organs is an independent prognostic factor of survival in patients with brain metastasis from NSCLC, irrespective of the pattern of extracranial organ involvement.

    The potential of intensity-modulated radiation therapy (IMRT) as opposed to three-dimensional conformal radiotherapy (3D-CRT) is analyzed for two different concepts of fluorodeoxyglucose positron emission tomography (FDG PET)-based target volume delineation in locally advanced non-small cell lung cancer (LA-NSCLC): involved-field radiotherapy (IF-RT) vs. elective nodal irradiation (ENI). Treatment planning was performed for 41 patients with LA-NSCLC, using four different planning approaches (3D-CRT-IF, 3D-CRT-ENI, IMRT-IF, IMRT-ENI). ENI included a boost irradiation after 50 Gy. For each plan, maximum dose escalation was calculated based on prespecified normal tissue constraints. The maximum prescription dose (PD), tumor control probability (TCP), conformal indices (CI), and normal tissue complication probabilities (NTCP) were analyzed. IMRT resulted in statistically significant higher prescription doses for both target volume concepts as compared with 3D-CRT (ENI: 68.4 vs. 60.9 Gy, p ENI, there was a considerable theoretical increase in TCP (IMRT: 27.3 vs. 17.7 %, p ENI: 12.3 vs. 30.9 % p < 0.0001; IF: 15.9 vs. 24.1 %; p < 0.001). The IMRT technique and IF target volume delineation allow a significant dose escalation and an increase in TCP. IMRT results in an improved sparing of OARs as compared with 3D-CRT at equivalent dose levels.

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

    Hsa-microRNA-187-3p (miR-187-3p) has recently been discovered having anticancer efficacy in different organs. However, the role of miR-187-3p on non-small cell lung cancer (NSCLC) is still ambiguous. In this study, we investigated the role of miR-187-3p on the development of NSCLC. The results indicated that miR-187-3p was significantly down-regulated in primary tumor tissues and very low levels were found in NSCLC cell lines. Ectopic expression of miR-187-3p in NSCLC cell lines significantly suppressed cell growth as evidenced by cell viability assay and colony formation assay, through inhibition of BCL6. In addition, miR-187-3p induced apoptosis, as indicated by concomitantly with up-regulation of the activities of caspase-3 and caspase-7, and inhibited cellular migration and invasiveness through inhibition of BCL6. Further, oncogene BCL6 was revealed to be a putative target of miR-187-3p, which was inversely correlated with miR-187-3p expression in NSCLC. Taken together, our results demonstrated that miR-187-3p played a pivotal role on NSCLC through inhibiting cell proliferation, migration, invasion, and promoting apoptosis by targeting oncogenic BCL6.

    Given the success of cabazitaxel in patients with prostate cancer who progressed after receiving prior chemotherapy, its preclinical efficacy in various cell lines and possible ability to cross blood-brain barrier, cabazitaxel was hypothesized to increase objective response rate (ORR) in second-line setting in non-small cell lung cancer (NSCLC). This was a phase II 2-stage trial in 28 patients using two different treatment schedules (A: 20 mg/m(2) every 3 weeks intravenously and B: 8.4 mg/m(2) intravenously weekly) to determine the ORR of cabazitaxel with secondary end points including progression-free survival (PFS), safety, and overall survival (OS). There was one objective response in schedule B. PFS and OS of schedule A was 3 and 6 months, respectively. PFS and OS of schedule B was 3 and 13 months, respectively. The stable disease rate was higher in schedule A (SD = 69.23 %; 95 % CL 38.57, 90.90) as compared to schedule B (SD = 38.46 %; 95 % CL 13.86, 68.42), but this difference was not statistically significant (P value = 0.1156). There were two grade 5 toxicities from sepsis. Hematuria of any grade developed in greater percentage of patients (35%) as compared to previous cabazitaxel phase 3 trial and led to change in our protocol. Response to cabazitaxel in NSCLC was not as robust as seen in prostate cancer and not superior to currently used agents such as docetaxel, pemetrexed, and erlotinib. In absence of significant objective responses, the second stage of the study was not undertaken.

    BACKGROUND: Most chemotherapeutics are administrated intravenously (iv), but some are also available in an oral (po) formulation. This study was designed with the primary objective to estimate the patients' preference for po or iv vinorelbine in combination with carboplatin for the palliative...... treatment of non-small cell lung cancer (NSCLC). Secondary aims were to evaluate toxicity, efficacy, and subjective reasons the preference. PATIENTS AND METHODS: Sixty-one patients were randomized in a cross-over trial to two cycles of carboplatin day 1 and vinorelbine day 1 and day 8 iv followed by two...... cycles of carboplatin and vinorelbine po, or the opposite. Patients, who did not show progressive disease after four cycles, had a free choice of iv or po vinorelbine for the next two cycles. RESULTS: Forty-three patients were evaluable for preference and 32 (74%, 95% CI 61-88%) chose po (p

    Evidence has suggested survival benefits of maintenance for advanced NSCLC patients not progressing after first-line chemotherapy. Additionally, particular first-line targeted therapies have shown survival improvements in selected populations. Optimal first-line and maintenance therapies remain unclear. Here, currently available evidence was synthesized to elucidate optimal first-line and maintenance therapy within patient groups. Literature was searched for randomized trials evaluating first-line and maintenance regimens in advanced NSCLC patients. Bayesian network meta-analysis was performed within molecularly and clinically selected groups. The primary outcome was combined clinically meaningful OS and PFS benefits. A total of 87 records on 56 trials evaluating first-line treatments with maintenance were included. Results showed combined clinically meaningful OS and PFS benefits with particular first-line with maintenance treatments, (1) first-line intercalated chemotherapy+erlotinib, maintenance erlotinib in patients with EGFR mutations, (2) first-line afatinib, maintenance afatinib in patients with EGFR deletion 19, (3) first-line chemotherapy + bevacizumab, maintenance bevacizumab in EGFR wild-type patients, (4) chemotherapy+conatumumab, maintenance conatumumab in patients with squamous histology, (5) chemotherapy+cetuximab, maintenance cetuximab or chemotherapy + necitumumab, maintenance necitumumab in EGFR FISH-positive patients with squamous histology, and (6) first-line chemotherapy+bevacizumab, maintenance bevacizumab or first-line sequential chemotherapy+gefitinib, maintenance gefitinib in patients clinically enriched for EGFR mutations with nonsquamous histology. No treatment showed combined clinically meaningful OS and PFS benefits in patients with EGFR L858R or nonsquamous histology. Particular first-line with maintenance treatments show meaningful OS and PFS benefits in patients selected by EGFR mutation or histology. Further research is needed

    While changes in heme oxygenase (HO-1) in lung cancer have already been reported, conflicting results were obtained for enzyme expression in human lung cancer specimens. Therefore, the aim of this work was to study HO-1 expression in a large collection of human lung cancer samples. For this purpose, we analyzed the expression of HO-1 in an organized tissue microarray (TMA) and investigated its correlation with clinicopathological data. Ninety-six percent of tumor samples were positive for HO-1, and the expression of HO-1 was significantly higher in cancerous than in non-cancerous tissues. Importantly, HO-1 expression correlated with advanced stages and lymph node involvement. Additionally, quantitative RT-PCR in 18 pairs of human lung carcinomas and their adjacent non-malignant tissues was performed. Our results demonstrate that HO-1 protein is upregulated in epithelial malignant cells in NSCLC and its expression is associated with higher stages of the disease. Additionally, different subcellular localization is observed between tumor and adjacent non-malignant tissues. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

  17. Elective nodal irradiation (ENI) vs. involved field radiotherapy (IFRT) for locally advanced non-small cell lung cancer (NSCLC): A comparative analysis of toxicities and clinical outcomes.

    Elective nodal irradiation (ENI) and involved field radiotherapy (IFRT) are definitive radiotherapeutic approaches used to treat patients with locally advanced non-small cell lung cancer (NSCLC). ENI delivers prophylactic radiation to clinically uninvolved lymph nodes, while IFRT only targets identifiable gross nodal disease. Because clinically uninvolved nodal stations may harbor microscopic disease, IFRT raises concerns for increased nodal failures. This retrospective cohort analysis evaluates failure rates and treatment-related toxicities in patients treated at a single institution with ENI and IFRT. We assessed all patients with stage III locally advanced or stage IV oligometastatic NSCLC treated with definitive radiotherapy from 2003 to 2008. Each physician consistently treated with either ENI or IFRT, based on their treatment philosophy. Of the 108 consecutive patients assessed (60 ENI vs. 48 IFRT), 10 patients had stage IV disease and 95 patients received chemotherapy. The median follow-up time for survivors was 18.9 months. On multivariable logistic regression analysis, patients treated with IFRT demonstrated a significantly lower risk of high grade esophagitis (Odds ratio: 0.31, p = 0.036). The differences in 2-year local control (39.2% vs. 59.6%), elective nodal control (84.3% vs. 84.3%), distant control (47.7% vs. 52.7%) and overall survival (40.1% vs. 43.7%) rates were not statistically significant between ENI vs. IFRT. Nodal failure rates in clinically uninvolved nodal stations were not increased with IFRT when compared to ENI. IFRT also resulted in significantly decreased esophageal toxicity, suggesting that IFRT may allow for integration of concurrent systemic chemotherapy in a greater proportion of patients.

    Lung cancer causes more than 150000 deaths annually in the United States alone, of which non-small cell lung cancer (NSCLC) accounts for 80%. Our studies demonstrated that NSCLC cells were sensitive to leflunomide and its metabolite teriflunomide, a FDA approved drug, which was a well-known immunomodulatory drug for relapsing multiple sclerosis (MS). In the present studies, we found first time that they displayed anti-tumor activity of NSCLC in vitro and in vivo. Potent anti-cancer effects in NSCLC in vitro, including inhibiting NSCLC cells viability, arresting cell cycle at the G0/G1 phase, inducing cell apoptosis, delaying and suppressing NSCLC cells colony-forming ability and cell motility, could be achieved with this agent. Meanwhile, we provided evidence that these effects were applicable in vivo by using H460 cells xenograft model in nude mice. In addition, to comprehensively clarify the mechanisms of teriflunomide in NSCLC, we explored a genome-wide transcriptomic analysis, and found that teriflunomide was involved in multiple signaling pathways and cellular processes, such as cell cycle, apoptosis, MAPK and p53 signaling pathway. Taken together, the results of our studies provided insights into a novel anti-cancer effect of leflunomide and teriflunomide on NSCLC and might open new therapeutic avenues for the treatment of NSCLC.

    The potential of intensity-modulated radiation therapy (IMRT) as opposed to three-dimensional conformal radiotherapy (3D-CRT) is analyzed for two different concepts of fluorodeoxyglucose positron emission tomography (FDG PET)-based target volume delineation in locally advanced non-small cell lung cancer (LA-NSCLC): involved-field radiotherapy (IF-RT) vs. elective nodal irradiation (ENI). Treatment planning was performed for 41 patients with LA-NSCLC, using four different planning approaches (3D-CRT-IF, 3D-CRT-ENI, IMRT-IF, IMRT-ENI). ENI included a boost irradiation after 50 Gy. For each plan, maximum dose escalation was calculated based on prespecified normal tissue constraints. The maximum prescription dose (PD), tumor control probability (TCP), conformal indices (CI), and normal tissue complication probabilities (NTCP) were analyzed. IMRT resulted in statistically significant higher prescription doses for both target volume concepts as compared with 3D-CRT (ENI: 68.4 vs. 60.9 Gy, p < 0.001; IF: 74.3 vs. 70.1 Gy, p < 0.03). With IMRT-IF, a PD of at least 66 Gy was achieved for 95 % of all plans. For IF as compared with ENI, there was a considerable theoretical increase in TCP (IMRT: 27.3 vs. 17.7 %, p < 0.00001; 3D-CRT: 20.2 vs. 9.9 %, p < 0.00001). The esophageal NTCP showed a particularly good sparing with IMRT vs. 3D-CRT (ENI: 12.3 vs. 30.9 % p < 0.0001; IF: 15.9 vs. 24.1 %; p < 0.001). The IMRT technique and IF target volume delineation allow a significant dose escalation and an increase in TCP. IMRT results in an improved sparing of OARs as compared with 3D-CRT at equivalent dose levels. (orig.)

    Using mathematical modelling allows to select a treatment's regimen across infinite possibilities. Here, we report the phase I assessment of a new schedule for metronomic vinorelbine in treating refractory advanced NSCLC and mesothelioma patients. Overall, 13 patients were screened and 12 were treated (50% male, median age: 68yrs), including 9 NSCLC patients. All patients received at least one week (3 doses) of treatment. At data cut-off, the median length of treatment was 6.5 weeks (1-32+). All the patients presented with at least one adverse event (AE) and six patients with a severe AE (SAE). One partial response and 5 stable diseases were observed. The median OS was 6.4 months (95% CI, 4.8 to 12 months). The median and mean vinorelbine's AUC were 122 ng/ml*h and 159 ng/ml*h, respectively, with the higher plasmatic vinorelbine exposure associated with the best ORR (difference of AUC comparison between responders and non-responders, p-value 0.017). The mathematical modelling determined the administration of vinorelbine, 60 mg on Day 1, 30 mg on Day 2 and 60 mg on Day 4 weekly until progression, as the best schedule. Advanced NSCLC or mesothelioma patients progressing after standard treatment were eligible for the trial. NCT02555007. Responses with acceptable safety profile were observed in heavily pretreated NSCLC and mesothelioma patients using oral vinorelbine at this metronomic dosage based on a mathematic modeling. This study demonstrates the feasibility of this new type of approach, as mathematical modeling may help to rationally decide the better regimen to be clinically tested across infinite possibilities.

    The majority of stage III patients with non-small cell lung cancer (NSCLC) are unsuitable for concurrent chemoradiotherapy, the non-surgical gold standard of care. As the alternative treatment options of sequential chemoradiotherapy and radiotherapy alone are associated with high local failure rates, various intensification strategies have been employed. There is evidence to suggest that altered fractionation using hyperfractionation, acceleration, dose escalation, and individualisation may be of benefit. The MAASTRO group have pioneered the concept of 'isotoxic' radiotherapy allowing for individualised dose escalation using hyperfractionated accelerated radiotherapy based on predefined normal tissue constraints. This study aims to evaluate whether delivering isotoxic radiotherapy using intensity modulated radiotherapy (IMRT) is achievable. Isotoxic IMRT is a multicentre feasibility study. From June 2014, a total of 35 patients from 7 UK centres, with a proven histological or cytological diagnosis of inoperable NSCLC, unsuitable for concurrent chemoradiotherapy will be recruited. A minimum of 2 cycles of induction chemotherapy is mandated before starting isotoxic radiotherapy. The dose of radiation will be increased until one or more of the organs at risk tolerance or the maximum dose of 79.2 Gy is reached. The primary end point is feasibility, with accrual rates, local control and overall survival our secondary end points. Patients will be followed up for 5 years. The study has received ethical approval (REC reference: 13/NW/0480) from the National Research Ethics Service (NRES) Committee North West-Greater Manchester South. The trial is conducted in accordance with the Declaration of Helsinki and Good Clinical Practice (GCP). The trial results will be published in a peer-reviewed journal and presented internationally.

    Full Text Available Beta catenin has been well documented in previous studies to be involved in non small cell lung cancer (NSCLC. Beta catenin abundance and transcriptional activity are significantly regulated by several factors. Though it is well known that Akt and Gsk3 beta are respective positive and negative regulators of beta catenin, however, no single study has so far documented how the expression and activity of both positive as well as negative regulators play favorable role on beta catenin expression and activity in NSCLC. In this study, we compared expression and activity of beta catenin and its regulators in normal lung cell WI38 and NSCLC cell A549 by western blot, qRT-PCR and luciferase assay. We observed that beta catenin positive regulators (Akt and Hsp90 and negative regulators (Gsk3 beta and microRNA-214 have differential expression and/or activity in NSCLC cell A549. However the differentially altered statuses of both the positive and negative regulators rendered cumulative positive effect on beta catenin expression and activity in A549. Our study thus suggests that chemotherapeutic modulations of regulating factors are crucial when abrogation and/or inhibition of key oncogenic proteins are necessary for cancer chemotherapy.

    MET is a receptor present in the membrane of NSCLC cells and is known to promote cell proliferation, survival and migration. MET gene copy number is a common genetic alteration and inhibition o MET emerges as a promising targeted therapy in NSCLC. Here we aim to combine in a meta-analysis, data on the effect of high MET gene copy number on the overall survival of patients with resected NSCLC. Two independent investigators applied parallel search strategies with the terms "MET AND lung cancer", "MET AND NSCLC", "MET gene copy number AND prognosis" in PubMed through January 2014. We selected the studies that investigated the association of MET gene copy number with survival, in patients who received surgery. Among 1096 titles that were identified in the initial search, we retrieved 9 studies on retrospective cohorts with adequate retrievable data regarding the prognostic impact of MET gene copy number on the survival of patients with NSCLC. Out of those, 6 used FISH and the remaining 3 used RT PCR to assess the MET gene copy number in the primary tumor. We calculated the I2 statistic to assess heterogeneity (I2 = 72%). MET gene copy number predicted worse overall survival when all studies were combined in a random effects model (HR = 1.78, 95% CI 1.22-2.60). When only the studies that had at least 50% of adenocarcinoma patients in their populations were included, the effect was significant (five studies, HR 1.55, 95% CI 1.23-1.94). This was not true when we included only the studies with no more than 50% of the patients having adenocarcinoma histology (four studies HR 2.18, 95% CI 0.97-4.90). Higher MET gene copy number in the primary tumor at the time of diagnosis predicts worse outcome in patients with NSCLC. This prognostic impact may be adenocarcinoma histology specific.

    Surgery remains the best curative option for appropriately selected patients with lung cancer. Evidence suggests that improving cardiovascular fitness and functional capacity can accelerate post-surgery recovery and reduce mortality. However, the effect of exercise intervention for patients surgically treated for Non-Small Cell Lung Cancer [NCSLC] has not been fully examined. This review examines the literature regarding exercise intervention for patients who are surgically treated for NSCLC focussing on three key areas: methodological quality, intervention design (e.g. duration, frequency, type) and outcomes measured. A search of Medline, EMBASE, CINAHL and PsychINFO was undertaken. Randomised Controlled Trials [RCTs] and non-RCTs including exercise training pre or post lung cancer resection were included. Descriptive characteristics were extracted and methodological quality assessed using Downs and Black appraisal checklist. Twenty studies (eight RCT's) were included: nine pre-surgical, nine post-surgical and two pre to post-surgical. The quality of evidence is questionable with many limitations (e.g. small samples, inadequate allocation concealment and a lack of clear reporting on timing, adverse events and follow-up). Regarding design of exercise intervention and outcomes measured, there was much variation between studies producing a disparate set of data. An optimal programme is still to be determined; however, suggestions are made relating to type of exercise (i.e. mixing aerobic, resistance and breathing exercises). Preliminary work from this review suggests that exercise intervention compared with usual care both pre and post-surgery is associated with improved cardiopulmonary exercise capacity, increased muscle strength and reduced fatigue, post-operative complications and hospital length of stay. Results concerning pulmonary function, quality of life, and blood gas analysis were variable and inconsistent. In order to implement exercise intervention

  7. Tumor-targeted SN38 inhibits growth of early stage non-small cell lung cancer (NSCLC in a KRas/p53 transgenic mouse model.

    Full Text Available Non-small cell lung cancer (NSCLC is the leading cause of cancer death worldwide, with a 5-year survival of only ~16%. Potential strategies to address NSCLC mortality include improvements in early detection and prevention, and development of new therapies suitable for use in patients with early and late stage diagnoses. Controlling the growth of early stage tumors could yield significant clinical benefits for patients with comorbidities that make them poor candidates for surgery: however, many drugs that limit cancer growth are not useful in the setting of long-term use or in comorbid patients, because of associated toxicities. In this study, we explored the use of a recently described small molecule agent, STA-8666, as a potential agent for controlling early stage tumor growth. STA-8666 uses a cleavable linker to merge a tumor-targeting moiety that binds heat shock protein 90 (HSP90 with the cytotoxic chemical SN38, and has been shown to have high efficacy and low toxicity, associated with efficient tumor targeting, in preclinical studies using patient-derived and other xenograft models for pancreatic, bladder, and small cell lung cancer. Using a genetically engineered model of NSCLC arising from induced mutation of KRas and knockout of Trp53, we continuously dosed mice with STA-8666 from immediately after tumor induction for 15 weeks. STA-8666 significantly slowed the rate of tumor growth, and was well tolerated over this extended dosing period. STA-8666 induced DNA damage and apoptosis, and reduced proliferation and phosphorylation of the proliferation-associated protein ERK1/2, selectively in tumor tissue. In contrast, STA-8666 did not affect tumor features, such as degree of vimentin staining, associated with epithelial-mesenchymal transition (EMT, or downregulate tumor expression of HSP90. These data suggest STA-8666 and other similar targeted compounds may be useful additions to control the growth of early stage NSCLC in patient

There have been major treatment advances in NSCLC over the past decade with the discovery of molecular drivers of NSCLC, which has ushered in an era of personalized medicine. There are several actionable genetic aberrations in NSCLC, such as epidermal growth factor receptor and anaplastic lymphoma kinase (ALK. In 3%–7% of NSCLC, a chromosomal inversion event in chromosome 2 leads to fusion of a portion of the ALK gene with the echinoderm microtubule–associated protein-like 4 (EML4 gene. The constitutive activation of the ALK fusion oncogene renders it vulnerable to therapeutic intervention. This review focuses on the first-line treatment of advanced ALK-positive NSCLC using ALK inhibitors. Crizotinib was the first agent proven to be efficacious as first-line treatment for ALK-positive NSCLC. However, acquired resistance inevitably develops. The central nervous system is a sanctuary site that represents a common site for disease progression as well. Hence, more potent, selective next-generation ALK inhibitors that are able to cross the blood–brain barrier have been developed for treatment against crizotinib-resistant ALK-positive NSCLC and are also currently being evaluated for first-line therapy as well. In this review, we provide summary of the clinical experience with these drugs in the treatment of ALK-positive NSCLC. Keywords: non-small-cell lung cancer, ALK, first line, crizotinib, pemetrexed

    Cisplatin is commonly used in non-small-cell lung cancer (NSCLC) chemotherapy; however, chemoresistance to cisplatin remains a great clinical challenge. Octamer-binding protein 4 (OCT4) has been reported to be overexpressed in NSCLC. In this study, we aimed to investigate the potential role of OCT4 in NSCLC with chemoresistance to cisplatin. Expressions of OCT4 was detected in NSCLC tissues and cell lines. We utilized siRNA to knock down OCT4 expression in human NSCLC cells and analyzed their phenotypic changes. We found that the difference of OCT4 expression between NSCLC and the adjacent non-tumourous tissues was statistically significant. Knockdown of OCT4 in NSCLC cells could decrease cell proliferation, and potentiate apoptosis induced by cisplatin, suggesting OCT4 may contribute to cisplatin resistance in NSCLC. Our findings indicate that targeting OCT4 could improve cisplatin effect in NSCLC, confirming their role in modulating cisplatin sensitivity.

    NSCLC is a leading cause of morbidity and mortality worldwide. It includes adeno- and squamous cell carcinoma. In the background, COPD and smoking play a vital role in development of NSCLC. Local progression and metastasis of NSCLC has been associated with various mechanisms, but in particular by a process called epithelial mesenchymal transition (EMT), which is implicated in COPD pathogenesis. In this study, we have investigated whether expression of EGFR (activation marker) and S100A4, vimentin and N-cadherin (as EMT) is different both in central and leading edge of NSCLC and to what extent related to EMT activity of both small and large airways, stage and differentiation of NSCLC. We have investigated EMT biomarkers (S100A4, vimentin, and N-cadherin), an epithelial activation marker (EGFR) and a vascularity marker (Type-IV collagen) in surgically resected tissue from patients with NSCLC (adeno- and squamous cell carcinoma), and compared them with expression in the corresponding non-tumorous airways. EGFR, S100A4, vimentin, N-cadherin expression was higher in tumor cells located at the peripheral leading edge of NSCLC when compared with centrally located tumor cells of same subjects (P < 0.01). Type-IV collagen-expressing blood vessels were also more at the leading edge in comparison with central parts of NSCLC. EGFR and S100A4 expression was related to differentiation status (P < 0.05) and TNM stage (P < 0.05) of NSCLC. Moreover, EMT markers in the leading edge were significantly related to airway EMT activity, while peripheral edge vascularity of squamous cell carcinoma only was significantly related to large airway Rbm vascularity (P < 0.05). EGFR- and EMT-related protein expression was markedly high in the peripheral leading edge of NSCLCs and related to tumor characteristics associated with poor prognosis. The relationships between EMT-related tumor biomarker expression and those in the airway epithelium and Rbm provide a background for utility of

    Introduction Although lung cancer is the leading cause of cancer death in women, few studies have investigated the hormonal influence on survival after a lung cancer diagnosis and results have been inconsistent. We evaluated the role of reproductive and hormonal factors in predicting overall survival in women with non–small-cell lung cancer (NSCLC). Methods Population-based lung cancer cases diagnosed between November 1, 2001 and October 31, 2005 were identified through the Metropolitan Detroit Surveillance, Epidemiology, and End Results Registry. Interview and follow-up data were collected for 485 women. Cox proportional hazard regression models were used to determine hazard ratios (HRs) for death after an NSCLC diagnosis associated with reproductive and hormonal variables. Results Use of hormone therapy (HT) was associated with improved survival (HR, 0.69; 95% confidence interval, 0.54–0.89), adjusting for stage, surgery, radiation, education level, pack-years of smoking, age at diagnosis, race, and a multiplicative interaction between stage and radiation. No other reproductive or hormonal factor was associated with survival after an NSCLC diagnosis. Increased duration of HT use before the lung cancer diagnosis (132 months or longer) was associated with improved survival (HR, 0.54; 95% confidence interval, 0.37–0.78), and this finding remained significant in women taking either estrogen alone or progesterone plus estrogen, never smokers, and smokers. Conclusion These findings suggest that HT use, in particular use of estrogen plus progesterone, and long-term HT use are associated with improved survival of NSCLC. PMID:24496005

    Reported herein are efforts to profile 4-aryl-N-phenylpyrimidin-2-amines in terms of their anti-cancer activity towards non small-cell lung carcinoma (NSCLC) cells. We have synthesized new 4-aryl-N-phenylpyrimidin-2-amines and assessed them in terms of their cytotoxicity (A549, NCI-H187, MCF7, Vero & KB) and physicochemical properties (logD7.4 and solubility). 13f and 13c demonstrated potent anti-cancer activity in A549 cells (0.2µM), compared to 0.4μM for the NSCLC drug Doxorubicin. 13f also displayed low experimental logD7.4 (2.9) and the best solubility (∼40μM). Compounds 13b and 13d showed the best balance of A549 anti-cancer activity and selectivity. 13g showed good activity and selectivity comparable with the anti-cancer drug Doxorubicin.

    Epithelial-mesenchymal transition (EMT) is able to drive metastasis during progression of multiple cancer types, including non-small cell lung cancer (NSCLC). As resistance to immunotherapy has been associated with EMT and immune exclusion in melanoma, it is important to understand alterations to T-cell infiltration and the tumor microenvironment during EMT in lung adenocarcinoma and squamous cell carcinoma. We conducted an integrated analysis of the immune landscape in NSCLCs through EMT scores derived from a previously established 16 gene signature of canonical EMT markers. EMT was associated with exclusion of immune cells critical in the immune response to cancer, with significantly lower infiltration of CD4 T-cells in lung adenocarcinoma and CD4/CD8 T-cells in squamous cell carcinoma. EMT was also associated with increased expression of multiple immunosuppressive cytokines, including IL-10 and TGF-β. Furthermore, overexpression of targetable immune checkpoints, such as CTLA-4 and TIM-3 were associated with EMT in both NSCLCs. An association may exist between immune exclusion and EMT in NSCLC. Further investigation is merited as its mechanism is not completely understood and a better understanding of this association could lead to the development of biomarkers that could accurately predict response to immunotherapy.

    Full Text Available Molecular targeted therapy has become more and more important in the treatment of non-small cell lung cancer (NSCLC. HGF/c-MET plays the pivotal role in the growth, development and tolerance to epidermal growth factor receptor tyrosine kinase inhibitor of NSCLC. Moreover it has become another heat point in the molecular targeted therapy of NSCLC. c-MET amplification or high expression was deemed to another significant gene modification beyond EGFR and ALK. In the preclinical studies, HGF/c-MET inhibitors have showed the promising anti-tumor effect. Recently, some phase II/III clinical trials have proved that these inhibitors could improve the survival of patients with NSCLC. Hence we performed this review to elaborate the research progress of c-MET inhibitor in the treatment of NSCLC.

    Purpose: The purpose of this research is investigating which texture features extracted from FDG-PET images by gray-level co-occurrence matrix(GLCM) have a higher prognostic value than the other texture features. Methods: 21 non-small cell lung cancer(NSCLC) patients were approved in the study. Patients underwent 18F-FDG PET/CT scans with both pre-treatment and post-treatment. Firstly, the tumors were extracted by our house developed software. Secondly, the clinical features including the maximum SUV and tumor volume were extracted by MIM vista software, and texture features including angular second moment, contrast, inverse different moment, entropy and correlation were extracted using MATLAB.The differences can be calculated by using post-treatment features to subtract pre-treatment features. Finally, the SPSS software was used to get the Pearson correlation coefficients and Spearman rank correlation coefficients between the change ratios of texture features and change ratios of clinical features. Results: The Pearson and Spearman rank correlation coefficient between contrast and SUV maximum is 0.785 and 0.709. The P and S value between inverse difference moment and tumor volume is 0.953 and 0.942. Conclusion: This preliminary study showed that the relationships between different texture features and the same clinical feature are different. Finding the prognostic value of contrast and inverse difference moment were higher than the other three textures extracted by GLCM.

    A phase II trial was launched to evaluate if neoadjuvant stereotactic ablative radiotherapy (SABR) before surgery improves oncologic outcomes in patients with stage I non-small cell lung cancer (NSCLC). We report a mandated interim safety analysis for the first 10 patients who completed protocol treatment. Operable patients with biopsy-proven T1-2 N0 NSCLC were eligible. SABR was delivered using a risk-adapted fractionation (54Gy/3 fractions, 55/5 or 60/8). Surgical resection was planned 10 weeks later at a high-volume center (>200 lung cancer resections annually). Patients were imaged with dynamic positron emission tomography-computed tomography scans using 18F-fludeoxyglucose (18F-FDG-PET CT) and dynamic contrast-enhanced CT before SABR and again before surgery. Toxicity was recorded using CTCAE version 4.0. Twelve patients were enrolled between 09/2014 and 09/2015. Two did not undergo surgery, due to patient or surgeon preference; neither patient has developed toxicity or recurrence. For the 10 patients completing both treatments, median age was 70 (range: 54-76), 60% had T1 disease, and 60% had adenocarcinoma. Median FEV1 was 73% predicted (range: 54-87%). Median time to surgery post-SABR was 10.1 weeks (range: 9.3-15.6 weeks). Surgery consisted of lobectomy (n = 8) or wedge resection (n = 2). Median follow-up post-SABR was 6.3 months. After combined treatment, the rate of acute grade 3-4 toxicity was 10%. There was no post-operative mortality at 90 days. The small sample size included herein precludes any definitive conclusions regarding overall toxicity rates until larger datasets are available. However, these data may inform others who are designing or conducting similar trials. NCT02136355 . Registered 8 May 2014.

    The discovery that a number of aberrant tumorigenic processes and signal transduction pathways are mediated by druggable protein kinases has led to a revolutionary change in nonsmall cell lung cancer (NSCLC) treatment. Epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) are the targets of several tyrosine kinase inhibitors (TKIs), some of them approved for treatment and others currently in clinical development. First-generation agents offer, in target populations, a substantial improvement of outcomes compared with standard chemotherapy in the treatment of advanced NSCLC. Unfortunately, drug resistance develops after initial benefit through a variety of mechanisms. Novel generation EGFR and ALK inhibitors are currently in advanced clinical development and are producing encouraging results in patients with acquired resistance to previous generation agents. The search for new drugs or strategies to overcome the TKI resistance in patients with EGFR mutations or ALK rearrangements is to be considered a priority for the improvement of outcomes in the treatment of advanced NSCLC.

    Full Text Available Background and objective TACE, Ar-He target cryosurgery and radioactive seeds implantation are the mainly micro-invasive methods in the treatment of lung cancer. This article summarizes the survival quality after treatment, the clinical efficiency and survival period, and analyzes the advantages and shortcomings of each methods so as to evaluate the clinical effect of non-small cell lung cancer with multiple minimally invasive treatment. Methods All the 139 cases were nonsmall cell lung cancer patients confirmed by pathology and with follow up from July 2006 to July 2009 retrospectively, and all of them lost operative chance by comprehensive evaluation. Different combination of multiple minimally invasive treatments were selected according to the blood supply, size and location of the lesion. Among the 139 cases, 102 cases of primary and 37 cases of metastasis to mediastinum, lung and chest wall, 71 cases of abundant blood supply used the combination of superselective target artery chemotherapy, Ar-He target cryoablation and radiochemotherapy with seeds implantation; 48 cases of poor blood supply use single Ar-He target cryoablation; 20 cases of poor blood supply use the combination of Ar-He target cryoablation and radiochemotheraoy with seeds implantation. And then the pre- and post-treatment KPS score, imaging data and the result of follow up were analyzed. Results The KPS score increased 20.01 meanly after the treatment. Follow up 3 years, 44 cases of CR, 87 cases of PR, 3 cases of NC and 5 cases of PD, and the efficiency was 94.2%. Ninety-nine cases of 1 year survival (71.2%, 43 cases of 2 years survival (30.2%, 4 cases with over 3 years survival and the median survival was 19 months. Average survival was (16±1.5months. There was no severe complications, such as spinal cord injury, vessel and pericardial aspiration. Conclusion Minimally invasive technique is a highly successful, micro-invasive and effective method with mild complications

  8. Signaling networks associated with AKT activation in non-small cell lung cancer (NSCLC: new insights on the role of phosphatydil-inositol-3 kinase.

    Directory of Open Access Journals (Sweden)

    Marianna Scrima

    Full Text Available Aberrant activation of PI3K/AKT signalling represents one of the most common molecular alterations in lung cancer, though the relative contribution of the single components of the cascade to the NSCLC development is still poorly defined. In this manuscript we have investigated the relationship between expression and genetic alterations of the components of the PI3K/AKT pathway [KRAS, the catalytic subunit of PI3K (p110α, PTEN, AKT1 and AKT2] and the activation of AKT in 107 surgically resected NSCLCs and have analyzed the existing relationships with clinico-pathologic features. Expression analysis was performed by immunohistochemistry on Tissue Micro Arrays (TMA; mutation analysis was performed by DNA sequencing; copy number variation was determined by FISH. We report that activation of PI3K/AKT pathway in Italian NSCLC patients is associated with high grade (G3-G4 compared with G1-G2; n = 83; p<0.05 and more advanced disease (TNM stage III vs. stages I and II; n = 26; p<0.05. In addition, we found that PTEN loss (41/104, 39% and the overexpression of p110α (27/92, 29% represent the most frequent aberration observed in NSCLCs. Less frequent molecular lesions comprised the overexpression of AKT2 (18/83, 22% or AKT1 (17/96, 18%, and KRAS mutation (7/63, 11%. Our results indicate that, among all genes, only p110α overexpression was significantly associated to AKT activation in NSCLCs (p = 0.02. Manipulation of p110α expression in lung cancer cells carrying an active PI3K allele (NCI-H460 efficiently reduced proliferation of NSCLC cells in vitro and tumour growth in vivo. Finally, RNA profiling of lung epithelial cells (BEAS-2B expressing a mutant allele of PIK3 (E545K identified a network of transcription factors such as MYC, FOS and HMGA1, not previously recognised to be associated with aberrant PI3K signalling in lung cancer.

    Non-small cell lung cancer (NSCLC) is one of the most prevalent cancers and is responsible for a large proportion of all cancer-related deaths. Current treatment options are inadequate, reflecting a substantial unmet clinical need. Increasing knowledge regarding the mechanisms and genetic aberrations underlying tumor development and growth has heralded a new era of therapy in oncology, moving away from indiscriminate cytotoxic chemotherapy toward more finely focused, targeted medicine. The development of small-molecule drugs and monoclonal antibodies directed toward specific components of dysfunctional molecular or immune pathways, and mutated genes specific to particular cancer types, is leading the field to more personalized and less toxic treatment options, many of which have demonstrated greater efficacy and survival benefits than their chemotherapeutic counterparts. Particularly successful examples are agents that interfere with the programmed death 1 (PD-1) pathway, which many tumors can hijack to avoid immune surveillance and editing. Pembrolizumab, a monoclonal antibody directed at PD-1 that blocks the engagement between PD-1 and its ligands, has been explored as a treatment for solid tumors, and demonstrated survival benefits in several studies. The use of PD-1 inhibitors such as nivolumab and pembrolizumab in advanced cancers is widespread, and pembrolizumab is available in more than 60 countries for at least one of the following: advanced melanoma, PD-L1-expressing NSCLC, head and neck squamous cell carcinoma, and adult and pediatric patients with refractory classical Hodgkin's lymphoma. This work provides a brief overview of the role of pembrolizumab in the treatment of advanced (recurrent/metastatic) NSCLC. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    Epidermal growth factor receptor (EGFR) is a non-small-cell lung cancer biomarker, based on which several near-patient-testing methods have been developed and applied to predict treatment response on individual patients. Existing methods for detection of EGFR mutation are costly, labor-intensive and time-consuming. In this paper, we report a novel EGFR mutation testing system, which is based on Mach-Zehnder Interferometer (MZI) sensor and isothermal solid-phase DNA amplification (IDA) technique, called MZI-IDA sensor system. The system can deliver results within 30 min and shows high sensitivity to detect trace amounts of genomic DNA (IDA sensor system is proved to be capable of fast and accurate detection of the L858R mutation of EGFR gene in clinical samples. This may greatly help the clinicians develop an appropriate treatment plan. Copyright © 2015 Elsevier B.V. All rights reserved.

    James L Sherwood

    Full Text Available Non-invasive mutation testing using circulating tumour DNA (ctDNA is an attractive premise. This could enable patients without available tumour sample to access more treatment options.Peripheral blood and matched tumours were analysed from 45 NSCLC patients. We investigated the impact of pre-analytical variables on DNA yield and/or KRAS mutation detection: sample collection tube type, incubation time, centrifugation steps, plasma input volume and DNA extraction kits.2 hr incubation time and double plasma centrifugation (2000 x g reduced overall DNA yield resulting in lowered levels of contaminating genomic DNA (gDNA. Reduced "contamination" and increased KRAS mutation detection was observed using cell-free DNA Blood Collection Tubes (cfDNA BCT (Streck, after 72 hrs following blood draw compared to EDTA tubes. Plasma input volume and use of different DNA extraction kits impacted DNA yield.This study demonstrated that successful ctDNA recovery for mutation detection in NSCLC is dependent on pre-analytical steps. Development of standardised methods for the detection of KRAS mutations from ctDNA specimens is recommended to minimise the impact of pre-analytical steps on mutation detection rates. Where rapid sample processing is not possible the use of cfDNA BCT tubes would be advantageous.

    The current study is conducted to investigate efficacy of the chemotherapy drug paclitaxel in combination with Avastin (Roche Diagnostics GmbH., Mannheim, Germany) (antiangiogenic agent) in treatment of malignant pleural effusions (MPEs).Twenty-four patients with non-small cell lung cancer were randomly assigned for 2 treatment approaches. Ten patients received paclitaxel (175 mg/m) alone, and 14 patients took a combination therapy of paclitaxel and Avastin (5 mg/kg). Efficacy of the treatment approaches in the patients was validated with the change in the MPE volume. Pharmacokinetic (PK) profile and urinary excretion rate of paclitaxel were analyzed with serum vascular endothelial growth factor (VEGF) level, and adverse events were examined as well.The combination therapy reduced the MPE level with a successful rate of 29% and a survival rate of 25% over the single paclitaxel treatment in the study cohort (both P < 0.05). PKs for the combined treatment displayed a rapid distribution of the anticancer drug paclitaxel with an obvious increase in its elimination half-life in the pleural fluid (both P < 0.01). Mean residence time of paclitaxel increased in the presence of Avastin (P < 0.01). Serum VEGF levels significantly reduced in the Avastin-treated patients as compared to the paclitaxel-treated ones (P < 0.01). The urinary excretion rate was similar in the study cohort. Incidence of adverse events for the 2 treatment approaches was similar in the patients.Intervention of Avastin enhances potency of paclitaxel in treatment of MPEs with the increased survival rate of the patients through inhibiting VEGF production and prolonging time of ongoing interaction between the chemotherapy drug and the tumor tissues.

    To assess feasibility and reproducibility of an Active Breathing Coordinator (ABC) used throughout radical radiotherapy for non-small-cell lung cancer, and compare lung dosimetric parameters between free-breathing and ABC plans. A total of 18 patients, recruited into an approved study, had free-breathing and ABC breath-hold treatment plans generated. Lung volume, the percentage volume of lung treated to a dose of ≥20 Gy (V(20)), and mean lung dose (MLD) were compared. Treatment (64 Gy in 32 fractions, 5 days/week) was delivered in breath-hold. Repeat breath-hold computed tomography scans were used to assess change in gross tumor volume (GTV) size and position. Setup error was also measured and potential GTV-planning target volume (PTV) margins calculated. Seventeen of 18 patients completed radiotherapy using ABC daily. Intrafraction tumor position was consistent, but interfraction variation had mean (range) values of 5.1 (0-25), 3.6 (0-9.7), and 3.5 (0-16.6) mm in the superoinferior (SI), right-left (RL), and anteroposterior (AP) directions, respectively. Tumor moved partially outside the PTV in 5 patients. Mean reduction in GTV from planning to end of treatment was 25% (p = 0.003). Potentially required PTV margins were 18.1, 11.9, and 11.9 mm in SI, RL, and AP directions. ABC reduced V(20) by 13% (p = 0.0001), V(13) by 12% (p = 0.001), and MLD by 13% (p breathing; lung volume increased by 41% (p cell lung cancer using ABC. Image guidance is recommended with ABC. The use of ABC can reduce dose volume parameters determining lung toxicity, and might allow for equitoxic radiotherapy dose escalation. Copyright © 2011. Published by Elsevier Inc.

    The treatment of advanced non-small cell lung cancer (NSCLC) is currently driven by the detection of targetable oncogenic drivers, i.e. epidermal growth factor receptor, echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase, etc. Those patients who are wildtype for known and valuable oncogenes can receive standard chemotherapy as first-line treatment, with the possibility of adding bevacizumab. With regard to second-line treatment, nintedanib can improve the efficacy of docetaxel. Nintedanib is a tyrosine kinase inhibitor targeting three angiogenesis-related transmembrane receptors. The usefulness of nintedanib as an anticancer agent for NSCLC has been proved by both preclinical and clinical phase I and II trials; however, its approval for the use in clinical practice has been possible because of the positive results of the LUME-Lung 1 trial (nintedanib + docetaxel versus docetaxel alone) in terms of progression-free survival and overall survival, and a manageable tolerability profile. Therefore, the good results seen in the clinical trials with nintedanib in the second-line setting for NSCLC patients with adenocarcinoma subtype are encouraging enough to recommend it in clinical practice.

    Retrospective studies suggested a benefit of first-line tyrosine kinase inhibitor (TKI) treatment continuation after response evaluation in solid tumors (RECIST) progression in epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC) patients. The aim of this multicenter observational retrospective study was to assess the frequency of this practice and its impact on overall survival (OS). The analysis included advanced EGFR-mutated NSCLC patients treated with first-line TKI who experienced RECIST progression between June 2010 and July 2012. Among the 123 patients included (67 ± 12.7 years, women: 69 %, non smokers: 68 %, PS 0-1: 87 %), 40.6 % continued TKI therapy after RECIST progression. There was no difference between the patients who did and did not continue TKI therapy with respect to progression-free survival (PFS1: 10.5 versus 9.5 months, p = 0.4). Overall survival (OS) showed a non-significant trend in favor of continuing TKI therapy (33.0 vs. 21.2 months, p = 0.054). Progressions were significantly less symptomatic in the TKI continuation group than in the discontinuation group (18 % vs. 37 %, p 1 (HR 4.33, 95 %CI: 2.21-8.47, p = 0.001), >1 one metastatic site (HR 1.96, 95 %CI: 1.06-3.61, p = 0.02), brain metastasis (HR 1.75, 95 %CI: 1.08-2.84, p = 0.02) at diagnosis, and a trend towards a higher risk of death in cases of TKI discontinuation after progression (HR 1.62, 95 %CI: 0.98-2.67, p = 0.056 ). In multivariate analysis only PS >1 (HR 6.27, 95 %CI: 2.97-13.25, p = 0.00001) and >1 metastatic site (HR 2.54, 95 %CI: 1.24-5.21, p = 0.02) at diagnosis remained significant. This study suggests that under certain circumstances, first-line TKI treatment continuation after RECIST progression is an acceptable option in EGFR-mutated NSCLC patients. NCT02293733.

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.

    Changes in tumour 3'-deoxy-3'-[{sup 18}F]fluorothymidine (FLT) uptake during concurrent chemo-radiotherapy in patients with non-small cell lung cancer (NSCLC) have been reported, at variable time points, in two pilot positron emission tomography (PET) studies. The aim of this study was to assess whether FLT changes occur early in response to radiotherapy (RT) without concurrent chemotherapy and whether such changes exceed test-retest variability. Sixteen patients with NSCLC, scheduled to have radical RT, underwent FLT PET once/twice at baseline to assess reproducibility and/or after 5-11 RT fractions to evaluate response. Primary and nodal malignant lesions were manually delineated on CT and volume, mean and maximum standardized uptake values (SUV{sub mean} and SUV{sub max}) estimated. Analysis included descriptive statistics and parameter fitting to a mixed-effects model accounting for patients having different numbers of evaluable lesions. In all, 35 FLT PET scans from 7 patients with a total of 18 lesions and 12 patients with a total of 30 lesions were evaluated for reproducibility and response, respectively. SUV{sub mean} reproducibility in primary tumours (SD 8.9 %) was better than SUV{sub max} reproducibility (SD 12.6 %). In nodes, SUV{sub mean} and SUV{sub max} reproducibilities (SD 18.0 and 17.2 %) were comparable but worse than for primary tumours. After 5-11 RT fractions, primary tumour SUV{sub mean} decreased significantly by 25 % (p = 0.0001) in the absence of significant volumetric change, whereas metastatic nodes decreased in volume by 31 % (p = 0.020) with a larger SUV{sub mean} decrease of 40 % (p < 0.0001). Similar changes were found for SUV{sub max}. Across this group of NSCLC patients, RT induced an early, significant decrease in lesion FLT uptake exceeding test-retest variability. This effect is variable between patients, appears distinct between primary and metastatic nodal lesions, and in primary tumours is lower than previously

    Despite excellent initial clinical responses of non-small cell lung cancer (NSCLC) patients to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs), many patients eventually develop resistance. According to a recent report, vacuolar H + ATPase (vATPase) is overexpressed and is associated with chemotherapy drug resistance in NSCLC. We investigated the combined effects of EGFR TKIs and vATPase inhibitors and their underlying mechanisms in the regulation of NSCLC cell death. We found that combined treatment with EGFR TKIs (erlotinib, gefitinib, or lapatinib) and vATPase inhibitors (bafilomycin A1 or concanamycin A) enhanced synergistic cell death compared to treatments with each drug alone. Treatment with bafilomycin A1 or concanamycin A led to the induction of Bnip3 expression in an Hif-1α dependent manner. Knock-down of Hif-1α or Bnip3 by siRNA further enhanced cell death induced by bafilomycin A1, suggesting that Hif-1α/Bnip3 induction promoted resistance to cell death induced by the vATPase inhibitors. EGFR TKIs suppressed Hif-1α and Bnip3 expression induced by the vATPase inhibitors, suggesting that they enhanced the sensitivity of the cells to these inhibitors by decreasing Hif-1α/Bnip3 expression. Taken together, we conclude that EGFR TKIs enhance the sensitivity of NSCLC cells to vATPase inhibitors by decreasing Hif-1α/Bnip3 expression. We suggest that combined treatment with EGFR TKIs and vATPase inhibitors is potentially effective for the treatment of NSCLC. - Highlights: • Co-treatment with EGFR TKIs and vATPase inhibitors induces synergistic cell death • EGFR TKIs enhance cell sensitivity to vATPase inhibitors via Hif-1α downregulation • Co-treatment of these inhibitors is potentially effective for the treatment of NSCLC.

    Full Text Available PURPOSE: Recent clinical trials showed that the sequential combination of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs and chemotherapy could prolong the PFS and/or OS of advanced non-small cell lung cancer (NSCLC patients with EGFR mutation. The aim of present study was to assess the optimal combination sequence and to explore its possible mechanism. METHODS: PC-9 cells and A549 cells, the lung adenocarcinoma cells with mutant and wide-type EGFR respectively, were treated with docetaxel/gefitinib alone or in different combination schedules. The EGFR and K-ras gene status was determined by qPCR-HRM technique. Cell proliferation was detected by MTT assay. The expression and phosphorylation of EGFR, ERK, Akt and IGF-1R were detected by western blot. Cell cycle distribution was observed by flow cytometry. RESULTS: Only sequential administration of docetaxel followed by gefitinib (D → G induced significant synergistic effect in both cell lines (Combination Index1.1, whereas the concurrent administration (D+G showed additive (0.9NSCLC cells, and the phosphorylation of EGFR and ERK might contribute to this effect.

    Immune checkpoint blockaders (ICBs) act by unbalancing the immune system, thus favoring the development of an immune-mediated antitumor effect. ICBs targeting the programmed cell death receptor-1 (PD-1) have recently been investigated in a number of advanced tumors, including non-small cell lung cancer (NSCLC). Nivolumab, a fully human IgG4 kappa directed against PD-1, has been the first ICB to be approved for second-line treatment of advanced NSCLC. Areas covered: In this review we focus on the clinical development of nivolumab for the treatment of advanced NSCLC, with an emphasis on its safety profile. In addition, we summarize the most common types of immune-related adverse events (irAEs) associated with nivolumab, mainly due to organ inflammation secondary to autoimmunity. Expert opinion: Nivolumab is the preferred treatment option for platinum-pretreated advanced NSCLC, having convincingly shown higher efficacy compared with standard docetaxel chemotherapy in phase III trials. The same trials showed far less incidence of either any grade and severe treatment-related AEs with nivolumab compared with chemotherapy. IrAEs associated with nivolumab are rarely severe in intensity, and often resolve with prompt management. Future studies will explore nivolumab in combination strategies with either platinum-based chemotherapy or other ICBs in treatment-naïve advanced NSCLC patients.

    Treatment outcomes for non-small-cell lung cancer (NSCLC) patients diagnosed at stage IIIA have been analyzed in many studies, which generally involve patients younger and healthier than the average patient with this disease. To analyze demographics and treatment outcomes in patients with stage IIIA NSCLC at a community cancer center. We reviewed charts of 226 patients diagnosed with stage IIIA NSCLC from January 2003 to December 2008 treated at our community cancer center. Results Median overall survival for all patients and sequentially and concurrently treated chemoradiation patients were 18 months, and 18 months, and 20 months, respectively. Median overall survival for women and men was 24 months and 16 months, respectively. Median overall survival for all patients and sequentially and concurrently treated chemoradiation patients were 18 months, and 18 months, and 20 months, respectively. Median overall survival for women and men was 24 months and 16 months, respectively. Study design was retrospective and some medical records were not available. However, this population is likely representative of patients treated in similar settings. In our population, advanced age and male gender were associated with lower median survival. Responses to concurrent and sequential chemoradiation seemed to differ based on age group, which may be useful as a prognostic guideline for similar populations. ©2015 Frontline Medical Communications.

A total of 70%–75% of all lung cancers are non-small cell lung cancer (NSCLC with two-thirds presenting with locally advanced or metastatic disease at diagnosis. Brain metastasis is one of the most common problems in the management of NSCLC, worsening the prognosis and quality of life of NSCLC patients. The epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs gefitinib and erlotinib have been tested in patients with NSCLC and brain metastasis. Icotinib is a new type of oral EGFR-TKI. In this report, we describe a patient with lung adenocarcinoma cancer with brain metastases who received icotinib treatment and kept satisfactory health-related quality of life for 1 year.

    Introduction: The therapeutic options for NSCLC are limited barring targeted drugs, such as EGFR tyrosine-kinase inhibitors and anaplastic lymphoma kinase inhibitors, for patients bearing oncogenic mutations. Platinum-based chemotherapy remains the best strategy for most patients. New targeted drugs, including mAbs and small molecules, are currently under clinical investigation for treating NSCLC patients. Areas covered: The authors of this article focus on farletuzumab , a mAb targeting folate receptor, which has been studied in ovarian cancer and various other malignancies. In this review, the authors review its potential as therapy for NSCLC, because of the biological rationale provided by the expression of folate receptor α in most of lung adenocarcinoma. The authors provide details of farletuzumab's mechanism of action and discuss the results from completed Phase I and Phase II clinical trials. They also highlight ongoing trials. Expert opinion: There are an increasing number of treatment options for NSCLC and it is hoped that farletuzumab could be added to them. That being said, further evidence for its use with NSCLC patients is still needed. It could have a synergic effect with pemetrexed, because these two drugs have a similar target, namely the folate pathway. This combined action could provide an improved efficacy, although there are some concerns about increased toxicity. However, the authors do note that the combination of farletuzumab with other cytotoxic drugs has not been shown to increase toxicity alone.

    Full Text Available Hepatocyte growth factor/c-MET (HGF/c-MET signaling pathway can be abnormal activated by many mechanisms such as c-MET mutation, amplification and the overexpression of HGF, and it plays an important role in the development of non-small cell lung cancer (NSCLC, as well as in the tolerance of epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI in NSCLC. Therefore, c-MET is a new molecular target for the therapy of NSCLC since EGFR and ALK. At present, although the c-MET inhibitors have shown a potential prospect in some clinical trials, its assessment of safety and effectiveness in clinical applications, and the choice of testing methods and standards still need a further discussion. In this paper, we summarized the mechanism of c-MET in NSCLC, as well as its treatment prospect and selection of testing methods.

    Brain metastases are not only the most common intracranial neoplasm in adults but also very prevalent in patients with lung cancer. Patients have been grouped into different classes based on the presence of prognostic factors such as control of the primary tumor, functional performance status, age, and number of brain metastases. Patients with good prognosis may benefit from more aggressive treatment because of the potential for prolonged survival for some of them. In this review, we will comprehensively discuss the therapeutic options for treating brain metastases, which arise mostly from a lung cancer primary. In particular, we will focus on the patient selection for combined modality treatment of brain metastases, such as surgical resection or stereotactic radiosurgery (SRS) combined with whole brain irradiation; the use of radiosensitizers; and the neurocognitive deficits after whole brain irradiation with or without SRS. The benefit of prophylactic cranial irradiation (PCI) and its potentially associated neuro-toxicity for both small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) are also discussed, along with the combined treatment of intrathoracic primary disease and solitary brain metastasis. The roles of SRS to the surgical bed, fractionated stereotactic radiotherapy, WBRT with an integrated boost to the gross brain metastases, as well as combining WBRT with epidermal growth factor receptor (EGFR) inhibitors, are explored as well.

    To assess the feasibility of non-Gaussian DWI as part of a FDG-PET/MRI protocol in patients with histologically proven non-small cell lung cancer. 15 consecutive patients with histologically proven NSCLC (mean age 61 ± 11 years) were included in this study and underwent whole-body FDG-PET/MRI following whole-body FDG-PET/CT. As part of the whole-body FDG-PET/MRI protocol, an EPI-sequence with 5 b-values (0, 100, 500, 1000 and 2000 s/mm(2)) was acquired for DWI of the thorax during free-breathing. Volume of interest (VOI) measurements were performed to determine the maximum and mean standardized uptake value (SUV(max); SUV(mean)). A region of interest (ROI) was manually drawn around the tumor on b=0 images and then transferred to the corresponding parameter maps to assess ADC(mono), D(app) and K(app). To assess the goodness of the mathematical fit R(2) was calculated for monoexponential and non-Gaussian analysis. Spearman's correlation coefficients were calculated to compare SUV values and diffusion coefficients. A Student's t-test was performed to compare the monoexponential and non-Gaussian diffusion fitting (R(2)). T staging was equal between FDG-PET/CT and FDG-PET/MRI in 12 of 15 patients. For NSCLC, mean ADC(mono) was 2.11 ± 1.24 × 10(-3) mm(2)/s, Dapp was 2.46 ± 1.29 × 10(-3) mm(2)/s and mean Kapp was 0.70 ± 0.21. The non-Gaussian diffusion analysis (R(2)=0.98) provided a significantly better mathematical fitting to the DWI signal decay than the monoexponetial analysis (R(2)=0.96) (pGaussian diffusion acquisitions are feasible. Non-Gaussian diffusion parameters show a good correlation with SUV and might provide additional information beyond monoexponential ADC, especially as non-Gaussian diffusion exhibits better mathematical fitting to the decay of the diffusion signal than monoexponential DWI.

    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

    Ongoing cancer cachexia trials evaluate sarcopenia by skeletal muscle index (SMI) at the L3 vertebrae level, commonly used as a standard. Routine chest CT institutional protocols widely differ in including L3. We investigated whether SMI at L1 assessment, rather than L3, would be reliable and more practicable for non-small cell lung cancer (NSCLC). NSCLC patients with routine CT chest had SMI measurements performed at L1 using Slice-O-Matic software. Accuracy of including L1 level, imaging quality, and ability to detect sarcopenia was collected and correlation of L1 SMI with body mass index (BMI) was performed. Thirty-seven patients with NSCLC (73 CT assessments) were enlisted at three institutions. Characteristics: 47% female; medians: age 59, KPS 80%; BMI 25.49, weight 72.97 kg, SMI 59.24. Sarcopenia was detected in 14.7% of patients; 20% had sarcopenic obesity. Of the 73 CTs, 94.5% included L1 (95% CI 86.6-98.5%). Three images (4%) were difficult to evaluate. Inclusion of L1 was similar among the three participating institutions (90.4 to 96.7% inclusion). BMI correlation with SMI was weak (r = 0.329). SMI assessment at L1 is achievable in patients with NSCLC receiving routine chest CT, with 96% having acceptable quality evaluations. Similar to results previously reported at L3, BMI showed poor correlation and low sensitivity to detect muscle mass loss. The use of CT at L1 is reliable and presents the opportunity for easier patient evaluation of sarcopenia in patients with lung cancer without the need for additional testing or radiation exposure.

    Full Text Available Abstract Background Cancer-Associated Fibroblasts (CAFs are significant components of solid malignancies and play central roles in cancer sustainability, invasion and metastasis. In this study we have investigated the invasive capacity and matrix remodelling properties of human lung CAFs after exposure to ablative doses of ionizing radiation (AIR, equivalent to single fractions delivered by stereotactic ablative radiotherapy (SART for medically inoperable stage-I/II non-small-cell lung cancers. Methods CAFs were isolated from lung tumour specimens from 16 donors. Initially, intrinsic radiosensitivity was evaluated by checking viability and extent of DNA-damage response (DDR at different radiation doses. The migrative and invasive capacities of CAFs were thereafter determined after a sub-lethal single radiation dose of 18 Gy. To ascertain the mechanisms behind the altered invasive capacity of cells, expression of matrix metalloproteinases (MMPs and their endogenous inhibitors (TIMPs were measured in the conditioned media several days post-irradiation, along with expression of cell surface integrins and dynamics of focal contacts by vinculin-staining. Results Exposing CAFs to 1 × 18 Gy resulted in a potent induction of multiple nuclear DDR foci (> 9/cell with little resolution after 120 h, induced premature cellular senescence and inhibition of the proliferative, migrative and invasive capacity. AIR promoted MMP-3 and inhibited MMP-1 appearance to some extent, but did not affect expression of other major MMPs. Furthermore, surface expression of integrins α2, β1 and α5 was consistently enhanced, and a dramatic augmentation and redistribution of focal contacts was observed. Conclusions Our data indicate that ablative doses of radiation exert advantageous inhibitory effects on the proliferative, migratory and invasive capacity of lung CAFs. The reduced motility of irradiated CAFs might be a consequence of stabilized focal contacts via integrins.

    To evaluate FDG PET-CT in the detection of unexpected pre-malignancy or second malignancy at the initial staging of patients with histologically proven non-small cell lung cancer (NSCLC) and its impact on management. Staging FDG PET-CT scans acquired between February 2006 and July 2010 in 649 patients (M=389; F=260) with NSCLC were reviewed for the presence of unexpected pre-malignancy or second primary. A "True-Positive" lesion represented a second primary or pre-malignant lesion. A "False-Positive" lesion was due to benign causes or an atypical site of metastasis from NSCLC. 77 (12%) patients were identified on PET-CT as having a potential pre-malignancy or second primary. 39 out of 77 (51%) patients had diagnostic verification where histopathology served as reference standard in 33 patients (85%) and the rest had endoscopy and progress PET-CT scans. 20 patients (3.1%) had a second primary (n=11) or pre-malignant lesions comprising dysplastic colorectal polyps (n=9), and additional therapy and/or management change for the index tumour was instigated in 17 patients (85%). In patients with a second primary, 3 (27%) patients had a high impact change in management from an initial curative intent to palliative. Staging FDG PET-CT is highly valuable in identifying second primary cancers or pre-malignant lesions in patients with NSCLC. When a second primary is detected on PET-CT, there is a high impact change in management in 27% of patients. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

  9. Rationale for the design of an oncology trial using a generic targeted therapy multi-drug regimen for NSCLC patients without treatment options (Review)

    LANGHAMMER, STEFAN

    2013-01-01

    Despite more than 70 years of research concerning medication for cancer treatment, the disease still remains one of the leading causes of mortality worldwide. Many cancer types lead to death within a period of months to years. The original class of chemotherapeutics is not selective for tumor cells and often has limited efficacy, while treated patients suffer from adverse side-effects. To date, the concept of tumor-specific targeted therapy drugs has not fulfilled its expectation to provide a key for a cure. Today, many oncology trials are designed using a combination of chemotherapeutics with targeted therapy drugs. However, these approaches have limited outcomes in most cancer indications. This perspective review provides a rationale to combine targeted therapy drugs for cancer treatment based on observations of evolutionary principles of tumor development and HIV infections. In both diseases, the mechanisms of immune evasion and drug resistance can be compared to some extent. However, only for HIV is a breakthrough treatment available, which is the highly active antiretroviral therapy (HAART). The principles of HAART and recent findings from cancer research were employed to construct a hypothetical model for cancer treatment with a multi-drug regimen of targeted therapy drugs. As an example of this hypothesis, it is proposed to combine already marketed targeted therapy drugs against VEGFRs, EGFR, CXCR4 and COX2 in an oncology trial for non-small cell lung cancer patients without further treatment options.

    Full Text Available In recent years, it has been well known that non-small cell lung cancer (NSCLC patients with mutations of epidermal growth factor receptor (EGFR response better to EGFR-tyrosine kinase inhibitor treatment. Although DNA-based assays (e.g. DNA sequencing are the most frequently used and a relatively reliable method to detect EGFR mutations, they are complex, time-consuming and relatively expensive for routine use in clinical laboratories, besides they require high quality tumor samples. In contrast, the immunohistochemistry (IHC methods make up fully for the above shortcomings and can serve as screening tests for EGFR mutations. However, there are many factors that can influence the results of IHC methods, such as different staining procedures, different antigen retrieval solutions and different sets of criteria, etc. Thus the IHC methods for detecting EGFR mutations have not been widely used in clinic and only in the research stage. This article reviews the use of IHC methods by different researchers and further discusses how to make the IHC methods work best for the detection of EGFR mutations.

Evidence about its efficacy in addition to second-line chemotherapy in non-small-cell-lung-cancer (NSCLC has been produced by two large randomized phase III clinical trials (LUME-Lung-1 and LUME-Lung-2, conducted in patients with pretreated NSCLC, without major risk factors for bleeding. In the LUME-Lung-1, the addition of nintedanib to docetaxel significantly improved progression-free survival (PFS, that was the primary endpoint of the trial (3.4 vs 2.7 months, HR 0.79; p=0.0019. Furthermore, a significant improvement in median overall survival (OS (from 10.3 to 12.6 months was observed in patients with adenocarcinoma histology, with a greater advantage in patients with adenocarcinoma who progressed within 9 months after start of first line treatment (from 7.9 to 10.9 months, and in patients with adenocarcinoma most refractory to first line chemotherapy (from 6.3 to 9.8 months. Adverse events were more common in the docetaxel plus nintedanib group and they included diarrhea and increased liver enzymes, while no statistically significant increase in the incidence of bleeding and hypertension events by the addition of nintedanib was observed. On these bases, the combination of docetaxel and nintedanib can be considered a new option for the second-line treatment for patients with advanced NSCLC with adenocarcinoma histology. Future challenges are the identification of predictive factors to help the decision of using nintedanib in eligible patients.

    Purpose: In the light of tumor regression and normal tissue changes, dose distributions can deviate undesirably from what was planned. As a consequence, replanning is sometimes necessary during treatment to ensure continued tumor coverage or to avoid overdosing organs at risk (OARs). Proton plans are generally thought to be less robust than photon plans because of the proton beam’s higher sensitivity to changes in tissue composition, suggesting also a higher likely replanning rate due to tumor regression. The purpose of this study is to compare dosimetric deviations between forward-calculated double scattering (DS) proton plans with IMRT plans upon tumor regression, and assesses their impact on clinical replanning decisions. Methods: Ten consecutive locally advanced NSCLC patients whose tumors shrank > 50% in volume and who received four or more CT scans during radiotherapy were analyzed. All the patients received proton radiotherapy (6660 cGy, 180 cGy/fx). Dosimetric robustness during therapy was characterized by changes in the planning objective metrics as well as by point-by-point root-mean-squared differences for the entire PTV, ITV, and OARs (heart, cord, esophagus, brachial plexus and lungs) DVHs. Results: Sixty-four pairs of DVHs were reviewed by three clinicians, who requested a replanning rate of 16.7% and 18.6% for DS and IMRT plans, respectively, with a high agreement between providers. Robustness of clinical indicators was found to depend on the beam orientation and dose level on the DVH curve. Proton dose increased most in OARs distal to the PTV along the beam path, but these changes were primarily in the mid to low dose levels. In contrast, the variation in IMRT plans occurred primarily in the high dose region. Conclusion: Robustness of clinical indicators depends where on the DVH curves comparisons are made. Similar replanning rates were observed for DS and IMRT plans upon large tumor regression.

    Full Text Available The phosphatidylinositol 3-kinases (PI3Ks are members of a family of intracellular lipid kinases that phosphorylate the 3’-hydroxyl group of phosphatidylinositol and phosphoinositides. PI3K regulate signaling pathways for neoplasia, including cell proliferation, adhesion, survival and motility. Different classes of PI3K have distinct roles in cellular signal transduction. PI3K pathway is activated by several different mechanisms in cancers, including, somatic mutation and gene amplification. In this review, we examine the literature addressing PI3K mutation status and gene amplification, with an emphasis on non-small cell lung cancer (NSCLC.

    Full Text Available TNF-related apoptosis-inducing ligand (TRAIL is a promising antitumor agent for its remarkable ability to selectively induce apoptosis in cancer cells, without affecting the viability of healthy bystander cells. The TRAIL tumor suppressor pathway is deregulated in many human malignancies including lung cancer. In human non-small cell lung cancer (NSCLC cells, sensitization to TRAIL therapy can be restored by increasing the expression levels of the tumor suppressor microRNA-212 (miR-212 leading to inhibition of the anti-apoptotic protein PED/PEA-15 implicated in treatment resistance. In this study, we exploited a previously described RNA aptamer inhibitor of the tyrosine kinase receptor Axl (GL21.T expressed on lung cancer cells, as a means to deliver miR-212 into human NSCLC cells expressing Axl. We demonstrate efficient delivery of miR-212 following conjugation of the miR to GL21.T (GL21.T-miR212 chimera. We show that the chimera downregulates PED and restores TRAIL-mediate cytotoxicity in cancer cells. Importantly, treatment of Axl+ lung cancer cells with the chimera resulted in (i an increase in caspase activation and (ii a reduction of cell viability in combination with TRAIL therapy. In conclusion, we demonstrate that the GL21.T-miR212 chimera can be employed as an adjuvant to TRAIL therapy for the treatment of lung cancer.

    Full Text Available Introduction. Lung cancer is currently the most common malignancy (1.6 million new cases annually, after non-melanoma skin cancer and the leading cause of cancer-related deaths (1.4 million annually. In Ukraine IV stage of the disease is diagnosed approximately in 27% of patients before their treatment. Chemotherapy, targeted therapy, radiation therapy and surgery are today the main treatment methods for patients with stage IV non-small cell lung cancer (NSCLC depending on clinical circumstances. Despite significant progress in the treatment of NSCLC a slight improvement in survival has been noted during the last decade. The aim of this scientific review was to present modern treatment methods for patients with stage IV of non-small cell lung cancer (chemotherapy, radiation therapy, targeted therapy, surgery, hormone therapy, immunotherapy. For patients with a preserved performance status (0-2 points by ECOG, double agent platinum based therapy extends survival, improves quality of life, and reduces disease-related symptoms. The addition of a third cytotoxic agent increases toxicity without any clinical benefit. Customizing treatment based on histology and molecular typing has become the standard of care. Epidermal growth factor receptor (EGFR genotyping and pathology subtyping should be considered routine in new diagnoses of metastatic NSCLC. Treatment options for those with somatic EGFR activating mutations include gefitinib until progression, followed by standard chemotherapy. Second-line chemotherapy is offered to a selected subgroup of patients upon progression and may include pemetrexed in non-squamous histology and docetaxel or erlotinib (or both in all histologies. Currently, only erlotinib is offered as a third-line option in unselected NSCLC patients after failure of first- and second-line chemotherapy. A paradigm shift in favor of maintenance therapy for patients with advanced stage disease has gained strength from recent data

    Full Text Available Background and objective Erlotinib, a selective inhibitor of epidermal growth factor receptor tyrosine kinase, has been approved effective in local advanced or metastatic non-small cell lung cancer (NSCLC. The aim of this study was to evaluate the efficacy and safety of erlotinib for the treatment of advanced NSCLC. Methods Ninety-two patients with advanced NSCLC who had failed or not tolerated or refused chemotherapy received 150 mg oral doses of erlotinib once daily until the disease progression or intolerable toxicity. Results Among the 92 NSCLC patients, 2 patient got complete response (2.2%, 22 partial response (23.9%, 48 stable disease (52.2% and 20 progressive disease (21.7%. The overall response rate and the disease controlled rate of erlotinib was 26.1% (24/92 and 78.3% (72/92, respectively. The response rate of erlotinib were significantly higher in rash and ECOG 0-1 than no rash and ECOG ≥ 2. The disease controlled rate of erlotinib was significantly higher in female and non-smokers than male and smokers (P < 0.05. The response rate of erlotinib did not show significant differences within pathological type or previous treatment. The most common side effects were rash and diarrhea with 84.8% and 31.5%, respectively, but usually were mild. Conclusion Erlotinib is effective and safe in the treatment of advanced NSCLC patients.

    Full Text Available Our previous findings have demonstrated that bee venom (BV has anti-cancer activity in several cancer cells. However, the effects of BV on lung cancer cell growth have not been reported. Cell viability was determined with trypan blue uptake, soft agar formation as well as DAPI and TUNEL assay. Cell death related protein expression was determined with Western blotting. An EMSA was used for nuclear factor kappaB (NF-κB activity assay. BV (1–5 μg/mL inhibited growth of lung cancer cells by induction of apoptosis in a dose dependent manner in lung cancer cell lines A549 and NCI-H460. Consistent with apoptotic cell death, expression of DR3 and DR6 was significantly increased. However, deletion of DRs by small interfering RNA significantly reversed BV induced cell growth inhibitory effects. Expression of pro-apoptotic proteins (caspase-3 and Bax was concomitantly increased, but the NF-κB activity and expression of Bcl-2 were inhibited. A combination treatment of tumor necrosis factor (TNF-like weak inducer of apoptosis, TNF-related apoptosis-inducing ligand, docetaxel and cisplatin, with BV synergistically inhibited both A549 and NCI-H460 lung cancer cell growth with further down regulation of NF-κB activity. These results show that BV induces apoptotic cell death in lung cancer cells through the enhancement of DR3 expression and inhibition of NF-κB pathway.

    Non-Small Cell Lung Cancer (NSCLC) is characterized by aggressiveness and includes the majority of thorax malignancies. The possibility of early stratification of patients as responsive and non-responsive to radiotherapy with a non-invasive method is extremely appealing. The distribution of the Fluorodeoxyglucose ({sup 18}F-FDG) in tumours, provided by Positron-Emission-Tomography (PET) images, has been proved to be useful to assess the initial staging of the disease, recurrence, and response to chemotherapy and chemo-radiotherapy (CRT). In the last years, particular efforts have been focused on the possibility of using ad interim {sup 18}F-FDG PET (FDG{sub int}) to evaluate response already in the course of radiotherapy. However, controversial findings have been reported for various malignancies, although several results would support the use of FDG{sub int} for individual therapeutic decisions, at least in some pathologies. The objective of the present review is to assemble comprehensively the literature concerning NSCLC, to evaluate where and whether FDG{sub int} may offer predictive potential. Several searches were completed on Medline and the Embase database, combining different keywords. Original papers published in the English language from 2005 to 2016 with studies involving FDG{sub int} in patients affected by NSCLC and treated with radiation therapy or chemo-radiotherapy only were chosen. Twenty-one studies out of 970 in Pubmed and 1256 in Embase were selected, reporting on 627 patients. Certainly, the lack of univocal PET parameters was identified as a major drawback, while standardization would be required for best practice. In any case, all these papers denoted FDG{sub int} as promising and a challenging examination for early assessment of outcomes during CRT, sustaining its predictivity in lung cancer. (orig.)

    Comprehensively review the evidence regarding the use of ayahuasca, an Amerindian medicine traditionally used to treat many different illnesses and diseases, to treat some types of cancer. An in-depth review of the literature was conducted using PubMed, books, institutional magazines, conferences and online texts in nonprofessional sources regarding the biomedical knowledge about ayahuasca in general with a specific focus in its possible relations to the treatment of cancer. At least nine case reports regarding the use of ayahuasca in the treatment of prostate, brain, ovarian, uterine, stomach, breast, and colon cancers were found. Several of these were considered improvements, one case was considered worse, and one case was rated as difficult to evaluate. A theoretical model is presented which explains these effects at the cellular, molecular, and psychosocial levels. Particular attention is given to ayahuasca's pharmacological effects through the activity of N,N-dimethyltryptamine at intracellular sigma-1 receptors. The effects of other components of ayahuasca, such as harmine, tetrahydroharmine, and harmaline, are also considered. The proposed model, based on the molecular and cellular biology of ayahuasca's known active components and the available clinical reports, suggests that these accounts may have consistent biological underpinnings. Further study of ayahuasca's possible antitumor effects is important because cancer patients continue to seek out this traditional medicine. Consequently, based on the social and anthropological observations of the use of this brew, suggestions are provided for further research into the safety and efficacy of ayahuasca as a possible medicinal aid in the treatment of cancer.

    Treatment and survival rates of patients with non-small-cell lung cancer (NSCLC) were compared between three French Cancer Registries (Calvados, Doubs, Tarn). The methodological issues in such comparisons are discussed. The treatments for NSCLC differed between the regions: radiotherapy tended to be preferred in Calvados (73% vs 21.3% surgery), whereas surgery was more frequently employed in Doubs and Tarn (27.7% and 37% respectively). The percentage of cases receiving no therapeutic treatment ranged from 7.8% (Calvados) to 26% (Tarn). Despite the differences in treatment, the overall survival rates were similar in the three regions. Adjustment for treatment in such a descriptive study may be misleading since different therapeutic strategies in different regions may lead to selection of patients of systematically better or poorer prognosis in the various treatment groups.

    Purpose: To compare the apparent diffusion coefficient (ADC) in non-small cell lung cancer lesions with standardized uptake values (SUV) derived from combined 18F-fluoro-deoxy-glucose-positron emission tomography/magnetic resonance imaging (FDG-PET/MRI) and those derived from FDG-PET/CT. Materials and Methods: In 18 consecutive patients with histologically proven NSCLC (17 men, 1 woman; mean age, 61 {+-} 12 years), whole-body FDG-PET/MRI was performed after whole-body FDG-PET/CT. Regions of interest (ROI) encompassing the entire primary tumor were drawn into FDG-PET/CT and FDG-PET/MR images to determine the maximum and mean standardized uptake value (SUV{sub max}; SUV{sub mean}) and into ADC parameter maps to assess mean ADC values. Pearson's correlation coefficients were calculated to compare SUV and ADC values. Results: The SUV{sub max} of NSCLC was 12.3 {+-} 4.8 [mean {+-} SD], and the SUV{sub mean} was 7.2 {+-} 2.8 as assessed by FDG-PET/MRI. The SUV{sub max} and SUV{sub mean} derived from FDG-PET/CT and FDG-PET/MRI correlated well (R = 0.93; p < 0.001 and R = 0.92; p < 0.001, respectively). The ADC{sub mean} of the pulmonary tumors was 187.9 {+-} 88.8 x 10{sup -5} {sup mm{sup 2/s}} [mean {+-} SD]. The ADC{sub mean} exhibited a significant inverse correlation with the SUV{sub max} (R = -0.72; p < 0.001) as well as with the SUVmean assessed by FDG-PET/MRI (R = -0.71; p < 0.001). Conclusion: This simultaneous PET/MRI study corroborates the assumed significant inverse correlation between increased metabolic activity on FDG-PET and restricted diffusion on DWI in NSCLC. (orig.)

  12. Laetrile treatment for cancer.

    2015-04-28

    Laetrile is the name for a semi-synthetic compound which is chemically related to amygdalin, a cyanogenic glycoside from the kernels of apricots and various other species of the genus Prunus. Laetrile and amygdalin are promoted under various names for the treatment of cancer although there is no evidence for its efficacy. Due to possible cyanide poisoning, laetrile can be dangerous. To assess the alleged anti-cancer effect and possible adverse effects of laetrile and amygdalin. We searched the following databases: CENTRAL (2014, Issue 9); MEDLINE (1951-2014); EMBASE (1980-2014); AMED; Scirus; CINAHL (all from 1982-2015); CAMbase (from 1998-2015); the MetaRegister; the National Research Register; and our own files. We examined reference lists of included studies and review articles and we contacted experts in the field for knowledge of additional studies. We did not impose any restrictions of timer or language. Randomized controlled trials (RCTs) and quasi-RCTs. We searched eight databases and two registers for studies testing laetrile or amygdalin for the treatment of cancer. Two review authors screened and assessed articles for inclusion criteria. We located over 200 references, 63 were evaluated in the original review, 6 in the 2011 and none in this update. However, we did not identify any studies that met our inclusion criteria. The claims that laetrile or amygdalin have beneficial effects for cancer patients are not currently supported by sound clinical data. There is a considerable risk of serious adverse effects from cyanide poisoning after laetrile or amygdalin, especially after oral ingestion. The risk-benefit balance of laetrile or amygdalin as a treatment for cancer is therefore unambiguously negative.

    Purpose: Tumor treatment response may potentially be assessed during radiation therapy (RT) by analyzing changes in CT-textures. We investigated the different early RT-responses between small cell (SCLC) and non-small cell lung cancer (NSCLC) as assessed by CT-texture. Methods: Daily diagnostic-quality CT acquired during routine CT-guided RT using a CT-on-Rails for 13-NSCLC and 5-SCLC patients were analyzed. These patient had ages ranging from 45–78 and 38–63 years, respectively, for NSCLC and SCLC groups, and tumor-stages ranging from T2-T4, and were treated with either RT or chemotherapy and RT with 45–66Gy/ 20–34 fractions. Gross-tumor volume (GTV) contour was generated on each daily CT by populating GTV contour from simulation to daily CTs with manual editing if necessary. CT-texture parameters, such as Hounsfield Unit (HU) histogram, mean HU, skewness, kurtosis, entropy, and short-run high-gray level emphasis (SRHGLE), were calculated in GTV from each daily CT-set using an in house software tool. Difference in changes of these texture parameters during RT between NSCLC and SCLC was analyzed and compared with GTV volume changes. Results: Radiation-induced changes in CT-texture were different between SCLC and NSCLC. Average changes from first to the last fractions for NSCLC and SCLC in GTV were 28±10(12–44) and 30±15(11–47) HU (mean HU reduction), 12.7% and 18.3% (entropy), 50% and 55% (SRHGLE), 19% and 22% (kurtosis), and 5.2% and 22% (skewness), respectively. Good correlation in kurtosis changes and GTV was seen (R{sup 2}=0.8923) for SCLC, but not for NSCLC (R{sup 2}=0.4748). SCLC had better correlations between GTV volume reduction and entropy (SCLC R{sup 2}=0.847; NSCLC R{sup 2}=0.6485), skewness (SCLC R{sup 2}=0.935; NSCLC R{sup 2}=0.7666), or SRHGLE (SCLC R{sup 2}=0.9619; NSCLC R{sup 2}=0.787). Conclusion: NSCLC and SCLC exhibited different early RT-responses as assessed by CT-texture changes during RT-delivery. The observed larger changes in

    Introduction: To investigate the potential correlation of the apparent diffusion coefficient assessed by diffusion-weighted MRI (DWI) and glucose metabolism determined by the standardized uptake value (SUV) at 18F-FDG PET/CT in non-small cell lung cancer (NSCLC). Materials and methods: 18F-FDG PET/CT and DWI (TR/TE, 2000/66 ms; b-values, 0 and 500 s/mm{sup 2}) were performed in 41 consecutive patients with histologically verified NSCLC. Analysing the PET-CT data calculation of the mean (SUV{sub mean}) and maximum (SUV{sub max}) SUV was performed. By placing a region-of-interest (ROI) encovering the entire tumor mean (ADC{sub mean}) and minimum ADC (ADC{sub min}) were determined by two independent radiologists. Results of 18F-FDG PET-CT and DWI were compared on a per-patient basis. For statistical analysis Pearson's correlation coefficient, Bland–Altman and regression analysis were assessed. Results: Data analysis revealed a significant inverse correlation of the ADC{sub min} and SUV{sub max} (r = −0.46; p = 0.032). Testing the correlation of the ADC{sub min} and SUV{sub max} for each histological subtype separately revealed that the inverse correlation was good for both adenocarcinomas (r = −0.47; p = 0.03) and squamouscell carcinomas (r = −0.71; p = 0.002), respectively. No significant correlation was found for the comparison of ADC{sub min} and SUV{sub mean} (r = −0.29; p = 0.27), ADC{sub mean} vs. SUV{sub mean} (r = −0.28; p = 0.31) or ADC{sub mean} vs. SUV{sub max} (r = −0.33; p = 0.23). The κ-value of 0.88 indicated a good agreement between both observers. Conclusion: This preliminary study is the first to verify the relation between the SUV and the ADC in NSCLC. The significant inverse correlation of these two quantitative imaging approaches points out the association of metabolic activity and tumor cellularity. Therefore, DWI with ADC measurement might represent a new prognostic marker in NSCLC.

    The objectives were (i) to confirm that diagnostic FDG-PET images could be obtained during thoracic radiotherapy, (ii) to verify that significant changes in FDG uptake or volume could be measured early enough to adapt the radiotherapy plan and (iii) to determine an optimal time window during the radiotherapy course to acquire a single FDG-PET examination that would be representative of tumour response. Ten non-small cell lung carcinoma (NSCLC) patients with significant PET/CT-FDG tumour radioactivity uptake (versus the background level), candidates for curative radiotherapy (RT, n=4; 60-70 Gy, 2 Gray per fraction, 5 fractions per week) or RT plus chemotherapy (CT-RT, n=6), were prospectively evaluated. Using a Siemens Biograph, 5 or 6 PET/CT scans (PET(n), n=0-5) were performed for each patient. Each acquisition included a 15-min thoracic PET with respiratory gating (RG) 60±5 min post-injection of the FDG (3.5 MBq/kg), followed by a standard, 5-min non-gated (STD) thoracic PET. PET(0) was performed before the first RT fraction. During RT, PET(1-5) were performed every 7 fractions, i.e., at 14 Gy total dose increment. FDG uptake was measured as the variation of SUV(max,PETn) versus SUV(max,PET0). Each lesions' volume was measured by (i) visual delineation by an experienced nuclear physician, (ii) 40% SUV(max) fixed threshold and (iii) a semi-automatic adaptive threshold method. A total of 53 FDG-PET scans were acquired. Seventeen lesions (6 tumours and 11 nodes) were visible on PET(0) in the 10 patients. The lesions were located either in or near the mediastinum or in the apex, without significant respiratory displacements at visual inspection of the gated images. Healthy lung did not cause motion artefacts in the PET images. As measured on 89 lesions, both the absolute and relative SUV(max) values decreased as the RT dose increased. A 50% SUV(max) decrease was obtained around a total dose of 45 Gy. Out of the 89 lesions, 75 remained visually identifiable during

    Information regarding chemotherapy in non-small cell lung cancer (NSCLC) patients with chronic respiratory failure is limited. We retrospectively analyzed patients who received oxygen therapy and underwent chemotherapy for NSCLC at our hospital. 6 patients with NSCLC receiving oxygen therapy (4 with unresectable lung cancer and 2 with postoperative recurrent lung cancer) underwent chemotherapy. 1 patient achieved a partial response and 1 achieved stable disease after first-line chemotherapy. The median overall survival (OS) was 247 days in all patients. Patients with unresectable NSCLC and recurrent NSCLC had median OS times of 282 and 239 days, respectively. Grade 3 lung infection occurred in 4 patients during chemotherapy treatment; however, there were no chemotherapy-related deaths. There is a possibility that chemotherapy could improve the survival of NSCLC patients who receive oxygen therapy. © 2016 S. Karger GmbH, Freiburg.

Several biomarkers and signaling pathways have been recognized as conceivable targets for treatment, and among them is the mesenchymal–epithelial transition/hepatocyte growth factor (c-MET/HGF axis. Alterations in the c-MET gene and aberrations of MET and HGF expression impact on lung cancer prognosis and are involved in resistance to epidermal growth factor receptor (EGFR inhibitors in non-small cell lung cancer (NSCLC patients harboring activating EGFR mutations. Several anti-MET and anti-HGF strategies are currently under investigation, including monoclonal antibodies. Ficlatuzumab is a monoclonal antibody directed against HGF that is currently under investigation in NSCLC. The aim of the present review is to critically review available data on HGF and ficlatuzumab in NSCLC. Keywords: non-small cell lung cancer, MET, hepatocyte growth factor, ficlatuzumab, AV-299

    Lung neoplasms are the leading cause of death by cancer worldwide. Non-small cell lung cancer (NSCLC) constitutes more than 80% of all lung malignancies and the majority of patients present advanced disease at onset. However, in the last decade, multiple oncogenic driver alterations have been discovered and each of them represents a potential therapeutic target. Although KRAS mutations are the most frequently oncogene aberrations in lung adenocarcinoma patients, effective therapies targeting KRAS have yet to be developed. Moreover, the role of KRAS oncogene in NSCLC remains unclear and its predictive and prognostic impact remains controversial. The study of the underlying biology of KRAS in NSCLC patients could help to determine potential candidates to evaluate novel targeted agents and combinations that may allow a tailored treatment for these patients. The aim of this review is to update the current knowledge about KRAS-mutated lung adenocarcinoma, including a historical overview, the biology of the molecular pathways involved, the clinical relevance of KRAS mutations as a prognostic and predictive marker and the potential therapeutic approaches for a personalized treatment of KRAS-mutated NSCLC patients.

    Cisplatin is the most potent and widespread used chemotherapy drug for lung cancer treatment. However, a large proportion of NSCLC patients were insensitive to chemotherapy. This study explored the role of miR-34a in regulating sensitivity of NSCLC cells to cisplatin and its downstream targets. The quantitative PCR result showed that miR-34a expression was upregulated in cisplatin sensitive NSCLC patients compared cisplatin insensitive NSCLC controls. By applying loss-and-gain function analysis, we demonstrated that miR-34a directly targeted to MYCN to sensitize NSCLC cells to cisplatin. In addition, p53 was found to monitor the expression of miR-34a in NSCLC cells after cisplatin treatment. Therefore, the sensitivity of cisplatin in NSCLC cells was modulated via p53/miR-34a/MYCN axis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Background. Recent clinical trials proven the clinically significant efficacy and tolerability of nivolumab, a programmed death 1 (PD-1 inhibitor, in previously treated patients with non-small cell lung cancer (NSCLC. Case Presentation. Here, we describe the case of a patient who experienced possible “disease flare” immediately after initiation of nivolumab treatment. A 54-year-old man was diagnosed with Stage IIB (T2N1M0 lung adenocarcinoma. After 7 years from recurrence, 10th line chemotherapy, nivolumab, was initiated. Six weeks later, after 3 cycles of nivolumab treatment, rapid lung cancer progression was observed with an increase in the size of the primary lesion, multiple novel nodules on both lungs, and multiple novel brain metastases. Conclusion. We believe that physicians should be made aware that, in a subset of NSCLC patients, disease flare might occur on nivolumab treatment.

    2017-04-03

    The usual treatments for patients with non-small-cell lung cancer (NSCLC), such as advanced lung adenocarcinoma, are unspecific and aggressive, and include lung resection, radiotherapy and chemotherapy. Recently, treatment with monoclonal antibodies and biological inhibitors has emerged as an effective alternative, generating effective results with few side effects. In recent years, several clinical trials using monoclonal antibodies presented potential benefits to NSCLC, and 4 of them are already approved for the treatment of NSCLC, such as cetuximab, bevacizumab, nivolumab and pembrolizumab. Also, biological inhibitors are attractive tolls for biological applications. Among the approved inhibitors are crizotinib, erlotinib, afatinib and gefitinib, and side effects are usually mild to intense. Nevertheless, biological molecule treatments are under development, and several new monoclonal antibodies and biological inhibitors are in trial to treat NSCLC. Also under trial study are as follows: anti-epidermal growth factor receptor (EGFR) antibodies (nimotuzumab and ficlatuzumab), anti-IGF 1 receptor (IGF-1R) monoclonal antibody (figitumumab), anti-NR-LU-10 monoclonal antibody (nofetumomab) as well as antibodies directly affecting the cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) molecule (ipilimumab and tremelimumab), to receptor activator of nuclear factor-kappa B ligand (RANKL) (denosumab) or to polymerase enzyme (veliparib and olaparib). Among new inhibitors under investigation are poly-ADP ribose polymerase (PARP) inhibitors (veliparib and olaparib) and phosphatidylinositol 3-kinase (PI3K) inhibitor (buparlisib). However, the success of immunotherapies still requires extensive research and additional controlled trials to evaluate the long-term benefits and side effects.

Erlotinib, another EGFR-TKI, was also approved a few years thereafter. In 2004, activating mutations in the EGFR gene were discovered to be a predictive biomarker for EGFR-TKI treatment, and gefitinib, which is not effective for patients with EGFR wild-type NSCLC, has since been used only in patients with EGFR-mutated NSCLC. In contrast, erlotinib is potentially effective for the treatment of EGFR wild-type NSCLC. Similar to gefitinib, erlotinib is also effective for EGFR-mutated NSCLC and has been used as an initial treatment for patients with advanced EGFR-mutated NSCLC. Both gefitinib and erlotinib can be used in a Japanese clinical setting. The approved daily dose of erlotinib (150 mg is equal to the maximum tolerated dose of erlotinib. In contrast, the daily dose of gefitinib has been set at 250 mg, which is approximately one-third of the maximum tolerated dose of gefitinib. Accordingly, a higher serum concentration can be achieved using erlotinib, compared with gefitinib. This advantage can be applied to the treatment of central nervous system metastases (brain metastasis and carcinomatous meningitis, the treatment of which is complicated by the difficulty drugs have penetrating the blood–brain barrier. Although patients with EGFR-mutated NSCLC respond dramatically to EGFR-TKIs, some patients have a poor response and the majority eventually undergo disease progression. To overcome such resistance, several novel treatment strategies, such as combination

    Selecting chemotherapy regimens guided by chemosensitivity tests can provide individualized therapies for cancer patients. The 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H- tetrazolium, inner salt (MTS) assay is one in vitro assay which has become widely used to evaluate the sensitivity to anticancer agents. The aim of this study was to evaluate the clinical applicability and accuracy of MTS assay for predicting chemotherapeutic response in unresectable NSCLC patients. Cancer cells were isolated from malignant pleural effusions of patients by density gradient centrifugation, and their sensitivity to eight chemotherapeutic agents was examined by MTS assay and compared with clinical response. A total of 37 patients participated in this study, and MTS assay produced results successfully in 34 patients (91.9%). The sensitivity rates ranged from 8.8% to 88.2%. Twenty-four of 34 patients who received chemotherapy were evaluated for in vitro-in vivo response analysis. The correlation between in vitro chemosensitivity result and in vivo response was highly significant (P=0.003), and the total predictive accuracy, sensitivity, specificity, positive predictive value, and negative predictive value for MTS assay were 87.5%, 94.1%, 71.4%, 88.9%, and 83.3%, respectively. The in vitro sensitivity for CDDP also showed a significant correlation with in vivo response (P=0.018, r=0.522). MTS assay is a preferable in vitro chemosensitivity assay that could be use to predict the response to chemotherapy and select the appropriate chemotherapy regimens for unresectable NSCLC patients, which could greatly improve therapeutic efficacy and reduce unnecessary adverse effects.

    Eliciting antitumor T-cell response by targeting the PD-1/PD-L1 axis with checkpoint inhibitors has emerged as a novel therapeutic strategy in non-small cell lung cancer (NSCLC). The identification of predictors for sensitivity or resistance to these agents is, therefore, needed. Herein, we investigate the correlation of metabolic information on FDG-PET with tissue expression of immune-checkpoints and other markers of tumor-related immunity in resected NSCLC patients. All patients referred to our institution for upfront surgical resection of NSCLC, who were investigated with FDG-PET prior to surgery, were consecutively included in the study. From January 2010 to May 2014, 55 patients (stage IA-IIIB; M:F = 42:13; mean age 68.9 years) were investigated. Sampled surgical tumor specimens were analyzed by immunohistochemistry (IHC) for CD68-TAMs (tumor-associated macrophages), CD8-TILs (tumor infiltrating lymphocytes), PD-1-TILs, and PD-L1 tumor expression. Immunoreactivity was evaluated, and scores were compared with imaging findings. FDG-PET images were analyzed to define semi-quantitative parameters: SUVmax and SUVmean. Metabolic information on FDG-PET was correlated with tissue markers expression and disease-free survival (DFS) considering a median follow-up of 16.2 months. Thirty-six adenocarcinomas (ADC), 18 squamous cell carcinomas (SCC), and one sarcomatoid carcinoma were analyzed. All tumors resulted positive at FDG-PET: median SUVmax 11.3 (range: 2.3-32.5) and SUVmean 6.4 (range: 1.5-13) both resulted significantly higher in SCC compared to other NSCLC histotypes (p = 0.007 and 0.048, respectively). IHC demonstrated a median immunoreactive surface covered by CD68-TAMs of 5.41 % (range: 0.84-14.01 %), CD8-TILs of 2.9 % (range: 0.11-11.92 %), PD-1 of 0.65 % (range: 0.02-5.87 %), and PD-L1 of 0.7 % (range: 0.03-10.29 %). We found a statistically significant correlation between SUVmax and SUVmean with the expression of CD8 TILs (rho = 0.31; p = 0.027) and PD-1

    The pharmacokinetics, pharmacodynamics, efficacy, toxicity, and place in therapy of nivolumab, a novel immunotherapy agent for the treatment of advanced non-small-cell lung cancer (NSCLC) of the squamous cell subtype are reviewed. Nivolumab is a novel programmed cell death 1 (PD-1) immune checkpoint inhibitor indicated as a second-line treatment for patients with NSCLC whose tumors exhibit squamous cell histology. Nivolumab has high affinity for the PD-1 receptor, and durable responses to treatment have been reported in clinical trials. In a Phase II study evaluating the drug's safety and efficacy in patients who had disease progression despite treatment with platinum-based doublet chemotherapy and at least one additional systemic therapy, nivolumab-treated patients had an objective response rate of 14.5%, with a 17% rate of grade 3 or 4 treatment-related adverse events; overall survival at one year was 40.8%. A head-to-head comparison of docetaxel and nivolumab for second-line treatment of squamous cell NSCLC demonstrated superior overall survival and reduced grade 3 or 4 adverse effects in nivolumab-treated patients. Nivolumab is a novel PD-1 immune checkpoint inhibitor that is effective for treating advanced squamous NSCLC in patients previously treated with platinum-based doublet chemotherapy or alternative first-line agents. Based on its improved efficacy and lower toxicity relative to docetaxel, nivolumab should be considered standard second-line therapy for this population.

    Harless William W

    2011-01-01

    Full Text Available Abstract Background Physiologic wound repair and tissue regeneration are associated with distinct cellular behaviors triggered by tissue damage. Normally quiescent stem cells proliferate to regenerate damaged tissue, while relatively immobile epithelial cells can transform into a motile, tissue invasive phenotype through a partial epithelial-mesenchymal transition. These distinct cellular behaviors may have particular relevance to how cancer cells can be predicted to behave after treatments damaging a tumor. Presentation of the hypothesis Surgery, chemotherapy, and radiation therapy trigger highly conserved wound healing pathways that: (1 facilitate the phenotypic transformation of surviving cancer cells into a highly mobile, metastatic phenotype through an EMT or epithelial-mesenchymal transition and (2 induce residual cancer stem cell proliferation. Testing the hypothesis Tissue damage caused by cancer treatments will trigger the release of distinct cytokines with established roles in physiologic wound healing, EMT induction, and stem cell activation. They will be released rapidly after treatment and detectable in the patient's blood. Careful histologic evaluation of cancerous tissue before and after treatment will reveal cellular changes suggestive of EMT induction (down regulation of cytokeratin expression and cancer stem cell enrichment (stem cell markers upregulated. Implications of the hypothesis Cancer cells surviving treatment will be more capable of metastasis and resistant to conventional therapies than the pre-treatment population of cancer cells. These changes will develop rapidly after treatment and, in distinct contrast to selection pressures fostering such changes, be triggered by highly conserved wound repair signals released after tissue damage. This pattern of tissue (tumor repair may be amenable to treatment intervention at the time it is upregulated.

    Objective: BRCA1 (breast cancer susceptibility gene 1) and RAP80 (receptor-associated protein 80) play key roles in predicting chemosensitivity of platinum and taxanes. A randomized trial was carried out to compare non-selected cisplatin-based chemotherapy with therapy customized according to BRCA1 and RAP80 expression. Methods: Advanced stage NSCLC patients whose tumor specimen was sufficient for molecular analysis were randomized (1∶3) to the control or experimental arm. Patients in the control arm received docetaxel/cisplatin; in the experimental arm, patients with low RAP80 expression received gemcitabine/cisplatin (Arm 1), those with intermediate/high RAP80 expression and low/intermediate BRCA1expression received docetaxel/cisplatin (Arm 2), and those with intermediate/high RAP80 expression and high BRCA1 expression received docetaxel alone (Arm 3). The primary end point was progression-free survival (PFS). Results: 226 patients were screened and 124 were randomized in this trial. ORR in the four subgroups was 22.6%, 48.4%, 30.3% and 19.2%, respectively (P=0.08); PFS was 4.74, 5.59, 3.78 and 2.73 months, respectively (P=0.55); and OS was 10.82, 14.44, 10.86 and 10.86 months, respectively (P=0.84). The common adverse effects included neutropenia, nausea, anemia and fatigue. Conclusions: No statistically significant difference of ORR, PFS or OS is observed in the experimental arms compared with the control arm. Patients with low RAP80 mRNA levels have a trend of better survival and higher response rate to gemcitabine/cisplatin chemotherapy.

    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

    Panobinostat (pano) is an FDA-approved histone deacetylase inhibitor. There is interest in evaluating alternate dosing schedules and novel combinations of pano for the treatment of upper aerodigestive and lung malignancies; thus we evaluated it in combination with Taxol, a chemotherapeutic with activity in both diseases. Dose-dependent synergy was observed in Non-Small Cell Lung Cancer (NSCLC) and Head and Neck Squamous Cell Carcinoma (HNSCC) cell lines and was due to senescence rather than potentiation of cell death. Senescence occurred following cisplatin- or Taxol-treatment in cell lines from both cancer types and was associated with decreased histone 3 (H3) acetylation and increased Bcl-xL expression: the latter a biomarker of senescence and target of anti-senescence therapeutics, or senolytics. Since H3 acetylation and Bcl-xL expression were altered in senescence, we subsequently evaluated pano as a senolytic in chemotherapy-treated cancer cells enriched for senescent cells. Pano caused cell death at significantly higher rates compared to repeat dosing with chemotherapy. This was associated with decreased expression of Bcl-xL and increased acetylated H3, reversing the expression patterns observed in senescence. These data support evaluating pano as a post-chemotherapy senolytic with the potential to kill persistent senescent cells that accumulate during standard chemotherapy in NSCLC and HNSCC.

    SUMMARY Background ALK-rearranged non-small-cell lung cancer (NSCLC) is sensitive to ALK tyrosine kinase inhibitors (ALKi) such as crizotinib, but resistance invariably develops, often with progression in the brain. Ceritinib is a more potent ALKi than crizotinib in vitro, crosses the blood-brain barrier in vivo and shows clinical responses in crizotinib-resistant disease. Here, we assessed whole-body and intracranial activity of ceritinib in both ALK-pretreated and ALKi-naïve patients with ALK-rearranged NSCLC. Methods The primary objective (to determine the maximum tolerated dose of ceritinib) of this first-in-human, phase I, open-label ASCEND-1 trial has been reported previously. In the analysis reported here, antitumour efficacy of ceritinib was evaluated in all patients with ALK-rearranged NSCLC (n=246) treated with ceritinib at the recommended dose of 750 mg/day. Additionally, as patients with untreated or locally treated neurologically stable brain metastases at baseline were permitted in this study, intracranial efficacy was retrospectively confirmed by independent neuroradiologists for 94 patients with baseline brain metastases and at least one post-baseline MRI/CT tumour assessment. This study is no longer recruiting patients; however, treatment and follow-up are ongoing. This study is registered with ClinicalTrials.gov, number NCT01283516. Findings Median follow-up at the time of this report was 11 1 months (interquartile range 6·7–15·2). Patients were mainly heavily pretreated (105/246 [42·7%] at least three prior regimens). The overall response rate was 72·3% (60/83; 95% confidence interval [CI] 61·4–81·6) for ALKi-naïve (n=83) and 56·4% (92/163; 95% CI 48·5–64·2) for ALKi-pretreated (n=163) patients. Median progression-free survival in ALKi-naïve and ALKi-pretreated patients was 18·4 (95% CI 11·1-non-estimable) and 6·9 (95% CI 5·6–8·7) months, respectively. Brain metastases by investigator assessment were reported at study

    The efficacy of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in EGFR-mutant non-small cell lung cancer (NSCLC) is limited by adaptive activation of cell survival signals. We hypothesized that both signal transducer and activator of transcription 3 (STAT3) and Src-YES-associated protein 1 (YAP1) signaling are dually activated during EGFR TKI treatment to limit therapeutic response. We used MTT and clonogenic assays, immunoblotting, and quantitative polymerase chain reaction to evaluate the efficacy of EGFR TKI alone and in combination with STAT3 and Src inhibition in three EGFR-mutant NSCLC cell lines. The Chou-Talalay method was used for the quantitative determination of drug interaction. We examined tumor growth inhibition in one EGFR-mutant NSCLC xenograft model (n = 4 mice per group). STAT3 and YAP1 expression was evaluated in tumors from 119 EGFR-mutant NSCLC patients (64 in an initial cohort and 55 in a validation cohort) by quantitative polymerase chain reaction. Kaplan-Meier and Cox regression analyses were used to assess the correlation between survival and gene expression. All statistical tests were two-sided. We discovered that lung cancer cells survive initial EGFR inhibitor treatment through activation of not only STAT3 but also Src-YAP1 signaling. Cotargeting EGFR, STAT3, and Src was synergistic in two EGFR-mutant NSCLC cell lines with a combination index of 0.59 (95% confidence interval [CI] = 0.54 to 0.63) for the PC-9 and 0.59 (95% CI = 0.54 to 0.63) for the H1975 cell line. High expression of STAT3 or YAP1 predicted worse progression-free survival (hazard ratio [HR] = 3.02, 95% CI = 1.54 to 5.93, P = .001, and HR = 2.57, 95% CI = 1.30 to 5.09, P = .007, respectively) in an initial cohort of 64 EGFR-mutant NSCLC patients treated with firstline EGFR TKIs. Similar results were observed in a validation cohort. Our study uncovers a coordinated signaling network centered on both STAT3 and Src-YAP signaling

    Full Text Available Platinum-based chemotherapy is one of the standard treatments for non-small-cell lung cancer (NSCLC, while its high toxicity and limited clinical effects raise big concerns. Shenfu injection (SFI has been commonly used as an adjutant chemotherapy drug for NSCLC in China. We ascertained the beneficial and adverse effects of SFI in combination with platinum-based chemotherapy for advanced NSCLC by using meta-analysis methods. The randomized controlled trials (RCTs involving advanced NSCLC treatment with SFI plus platinum-based chemotherapy versus chemotherapy alone were searched on 6 medical databases up to February 2017. Cochrane handbook 5.1.0 was applied to assess the quality of included trials and RevMan 5.3 software was employed for data analysis. 23 RCTs including 1574 patients met our inclusion criteria. We evaluated the following outcome measures: objective tumor response (ORR, disease control rate (DCR, Karnofsky performance score (KPS, adverse effects, and indicators of cellular immune function. The meta-analysis indicated that SFI plus platinum-based chemotherapy may benefit the patients with NSCLC on attenuated synergies of chemotherapy. These findings need to be confirmed by further rigorously designed high-quality and large-scale RCTs.

    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.

    Until 2004, docetaxel in monotherapy was the standard for second-line treatment of non-small cell lung cancer (NSCLC). Pemetrexed (P) has shown similar activity in this setting with a better adverse event profile. In Portugal, it was introduced in October of 2004. We have carried out a retrospective analysis of patients (pts) who received P for second-line NSCLC in Portugal from October 2004 to December 2006. Data were collected from the records of pts with locally advanced or metastatic NSCLC and failed first-line chemotherapy enrolled in centers participating in the Portuguese Lung Cancer Study Group (GECP). Objective response (OR; complete [CR] or partial [PR] response) was evaluated using RECIST and safety was assessed using serious or non-serious adverse events (SAEs/AEs). By December 2006, 19 GECP centers had enrolled 244 pts who had received P for ≥1cycle, and were considered evaluable for both objective response and safety. Demography: male/female, 175/69; median age, 57.0years (range 20-81); smoking status, y/ex/n, 116/57/71; adenocarcinoma / squamous-cell carcinoma/other histology, 141/72/31; mean time to progression (TTP) 8.07months. Disease control in 209 evaluable pts was observed in 116 (55.5%): 2 CR, 45 PR and 69 SD; mean TTP 4.70months. The majority of AEs were grade 3 anemia (15 pts) and neutropenia (18 pts). The mean overall survival was 17.27months. Our retrospective analysis has observed a similar disease control rate with P in 2nd line (55.5%), and TTP (4.7months) in our current unselected population to that published in the literature. P is an option for second-line NSCLC with a good tolerability. Rev Port Pneumol 2008; XIV (Sup.2): S9-S20. © 2008 Sociedade Portuguesa de Pneumologia/SPP.

    Non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancers. Traditional chemotherapy for this disease leads to serious side effects. Here we prepared an inhalable oridonin-loaded poly(lactic-co-glycolic)acid (PLGA) large porous microparticle (LPMP) for in situ treatment of NSCLC with the emulsion/solvent evaporation/freeze-drying method. The LPMPs were smooth spheres with many internal pores. Despite a geometric diameter of ~10 µm, the aerodynamic diameter of the spheres was only 2.72 µm, leading to highly efficient lung deposition. In vitro studies showed that most of oridonin was released after 1 h, whereas the alveolar macrophage uptake of LPMPs occurred after 8 h, so that most of oridonin would enter the surroundings without undergoing phagocytosis. Rat primary NSCLC models were built and administered with saline, oridonin powder, gemcitabine, and oridonin-loaded LPMPs via airway, respectively. The LPMPs showed strong anticancer effects. Oridonin showed strong angiogenesis inhibition and apoptosis. Relevant mechanisms are thought to include oridonin-induced mitochondrial dysfunction accompanied by low mitochondrial membrane potentials, downregulation of BCL-2 expressions, upregulation of expressions of BAX, caspase-3 and caspase-9. The oridonin-loaded PLGA LPMPs showed high anti-NSCLC effects after pulmonary delivery. In conclusion, LPMPs are promising dry powder inhalations for in situ treatment of lung cancer.

  8. Effect of ABCG2/BCRP Expression on Efflux and Uptake of Gefitinib in NSCLC Cell Lines.

    Directory of Open Access Journals (Sweden)

    Maricla Galetti

    Full Text Available BCRP/ABCG2 emerged as an important multidrug resistance protein, because it confers resistance to several classes of cancer chemotherapeutic agents and to a number of novel molecularly-targeted therapeutics such as tyrosine kinase inhibitors. Gefitinib is an orally active, selective EGFR tyrosine kinase inhibitor used in the treatment of patients with advanced non small cell lung cancer (NSCLC carrying activating EGFR mutations. Membrane transporters may affect the distribution and accumulation of gefitinib in tumour cells; in particular a reduced intracellular level of the drug may result from poor uptake, enhanced efflux or increased metabolism.The present study, performed in a panel of NSCLC cell lines expressing different ABCG2 plasma membrane levels, was designed to investigate the effect of the efflux transporter ABCG2 on intracellular gefitinib accumulation, by dissecting the contribution of uptake and efflux processes.Our findings indicate that gefitinib, in lung cancer cells, inhibits ABCG2 activity, as previously reported. In addition, we suggest that ABCG2 silencing or overexpression affects intracellular gefitinib content by modulating the uptake rather than the efflux. Similarly, overexpression of ABCG2 affected the expression of a number of drug transporters, altering the functional activities of nutrient and drug transport systems, in particular inhibiting MPP, glucose and glutamine uptake.Therefore, we conclude that gefitinib is an inhibitor but not a substrate for ABCG2 and that ABCG2 overexpression may modulate the expression and activity of other transporters involved in the uptake of different substrates into the cells.

    Full Text Available Brain metastases are frequently encountered in patients with non-small cell lung cancer (NSCLC and are a significant cause of morbidity and mortality. Antiangiogenesis therapy plays a major role in the management of brain metastases in lung cancer. Bevacizumab have become the novel method for the treatment of lung cancer with brain metastases beyond the whole brain radiation therapy, stereotactic radiosurgery and chemotherapy. Recently, more and more studies and trials laid emphasis on the bevacizumab for NSCLC with brain metastases treatment. The key point is the efficacy and safety. In this review, bevacizumab therapy of NSCLC with brain metastases were summarized.

    2016-12-01

    Next-generation sequencing technologies have provided us with a precise description of the mutational burden of cancers, making it possible to identify targetable oncogene addictions. However, the emergence of resistant clones is an inevitable limitation of therapies targeting these addictions. Alternative approaches to cancer treatment are therefore required. We propose here a novel approach, based on the notion of conflicting signals and on a phenotypic description of cancer cells. "Phenotype" is an inherently complex notion that we describe in the conceptual framework of the epigenetic landscape, with a view to bridging the gap between theory and practice at the patient's bedside. By passing from theory to the description of several examples, we will illustrate how this approach can facilitate data analysis and the design of new strategies for cancer treatment.

  11. Maintenance treatment after induction therapy in non-small cell lung cancer: latest evidence and clinical implications

    Gentzler, Ryan D.

    2014-01-01

    Non-small cell lung cancer (NSCLC) is the leading cause of cancer death in the industrialized world. Despite significant progress in early stage disease, survival rates for advanced disease remain low. Maintenance therapy is a treatment strategy that has been investigated extensively in NSCLC. Therapies that have been studied in this setting in randomized trials to date include chemotherapy and molecularly targeted agents. Following the development of multiple new agents that show activity in NSCLC and have a tolerable side-effect profile, there has been increasing interest in utilizing them to maintain response to initial therapy after treatment with platinum-based doublets. Two effective strategies have evolved: continuation and switch maintenance. Despite improvements in progression-free survival and often overall survival on multiple clinical trials, there remains considerable controversy around this treatment paradigm. Here, we briefly outline the evolution of this treatment strategy and examine the available data, including recently updated data from the PARAMOUNT, AVAPERL, and PointBreak maintenance trials. Ultimately, the decision to use maintenance chemotherapy requires a nuanced discussion between the patient and physician that adequately assesses benefits of prolonged therapy and impact in terms of toxicity, quality of life, and financial cost.

    Palliative effect of PDT in advanced NSCLC has been proven. Radachlorin® is a second generation photosensitizer that has quicker pharmacokinetics than first generation photosensitizers. Although there are reports describing Radachlorin®, limited data are available regarding its advantages in PDT. Advanced NSCLC patients with central airway obstruction were enrolled. Patients who had comorbidity effects on drug metabolism were excluded. All patients received 1mg/kg of Radachlorin®, 4 h before light irradiation. 200 J/cm² of laser was irradiated during 11 min 6 s. Bronchial toileting was performed the following day. A PFT was performed before and after PDT. The primary treatment outcome was improvement of airway obstruction, which was evaluated according to bronchoscopic findings and improvement of FEV1. Secondary treatment outcomes included the rate of PDT-related complications, one year survival rate and progression free survival. Ten patients were enrolled between June 2010 and May 2011. Their median age was 58.5 years and their baseline cancer stage was more than IIIA. 20% of patients showed successful results, 70% showed partially successful results and 10% showed an unsuccessful result. All patients showed improvement in their obstructive symptoms. The mean FEV1 before PDT was 1.70±0.69 L, while the mean FEV1 after PDT was 1.99±0.60 L (P=0.029). No patients had major complications. Eight patients were undergoing additional treatment after resolving airway obstruction. The one year survival rate after PDT was 70%. Radachlorin®-based PDT is safe and effective treatment for relieving central airway obstruction in advanced NSCLC. Copyright © 2013 Elsevier B.V. All rights reserved.

  13. Single nucleotide polymorphisms in lung cancer patients and cisplatin treatment

    2014-11-01

    Full Text Available Lung cancer is a major cause of mortality worldwide and non-small cell lung cancer (NSCLC accounts for over 80% of all cases of lung cancer. Despite efforts to develop and improve early screening methods, the majority of tumors are detected at advanced stages. For over 30 years, cisplatin (CDDP, or any of its analogues, has been used in the treatment of many types of tumors, including lung cancer. The use of platinum-based chemotherapeutics is limited by their toxicity and later on by the development of chemoresistance by tumor cells. The molecular mechanisms of CDDP resistance are not fully resolved. Genetic variants of DNA repair proteins, as well as proteins involved in drug accumulation or detoxification, play a crucial role in determining the cell’s response to platinum-based chemotherapy. The identification of selected gene polymorphisms could improve the prognosis of a patient’s response to therapy and overall survival. In this review we will focus on the gene polymorphisms involved in CDDP resistance, in particular in lung tumors, and discuss their potential as prognosis and survival markers.

  14. Drug Resistance to EGFR Inhibitors in Lung Cancer | Office of Cancer Genomics

    Science.gov (United States)

    The discovery of mutations in epidermal growth factor receptor (EGFR) has dramatically changed the treatment of patients with non-small-cell lung cancer (NSCLC), the leading cause of cancer deaths worldwide. EGFR-targeted therapies show considerable promise, but drug resistance has become a substantial issue. We reviewed the literature to provide an overview of the drug resistance to EGFR tyrosine kinase inhibitors (TKIs) in NSCLC. The mechanisms causing primary, acquired and persistent drug resistance to TKIs vary.

    We report a first case of a patient experiencing reactivation of pulmonary tuberculosis (TB) during treatment of oral tyrosine kinase inhibitor (TKI) with non-small cell lung cancer (NSCLC). A 44-year-old male patient visited the hospital with cough. He had been treated with erlotinib (oral TKI) for 8 months after being diagnosed as NSCLC with sensitive epidermal growth factor receptor mutation in our clinic. At initial chest imaging, the patient had fibroatelectatic calcified granuloma in the right upper lobe (RUL) apex as well as 1.9 cm × 2.5 cm sized cancer mass encasing the RUL bronchus. He had not been treated for active pulmonary TB before. He had no known history of contact with active TB patients. During the past treatment period, he had shown overall stable response to erlotinib for 8 months. However, chest computed tomography taken for the fourth response evaluation showed increased number and size of nodules with bronchial luminal narrowing in RUL compared to the last exam, suggesting disease progression. We performed bronchoscopy to re-biopsy the cancer mass. Mucosal biopsy and bronchial washing fluid culture revealed active endobronchial pulmonary TB rather than lung cancer progression. Based on these study results, we started anti-TB medications without changing chemotherapy regimen. After 7 months of treatment for pulmonary TB with erlotinib maintenance, he has been shown successful regression of pulmonary TB with stable chemotherapeutic response. Previously, several reports have described the effect of anti-cancer therapy on the treatment of active TB. However, there has been no case report presenting TB reactivation during oral TKI treatment in NSCLC. Therefore, we suggest that the risk of TB reactivation should be considered in patients with solid organ malignancies even if targeted agents are used. Moreover, misdiagnosis of disease progression must be ruled out.

    Full Text Available Background. Radiotherapy has been widely used for non-small-cell lung cancer (NSCLC, while its low efficacy and high toxicity raise big concerns. Astragalus (as a monarch drug-containing Chinese herbal prescriptions and radiotherapy were frequently coused for NSCLC in China; however, the effects were not systematically analyzed. Objective. To evaluate the benefits of Astragalus-containing Chinese herbal prescriptions combined with radiotherapy for NSCLC. Methods. The randomized controlled trials involving NSCLC treatment with Astragalus-containing Chinese herbal prescriptions combined with radiotherapy were searched. The Review Manager 5.1 software was employed for data analysis. Funnel plot and Egger’s test were applied to evaluate publication bias. Results. 29 eligible studies met our criteria. Of the studies, 8, 6, and 4 reported reduced risk of death at one year, two years, and three years, respectively. 26 studies revealed amended tumor response. Six studies showed improved Karnofsky performance status. Among the studies, 14 and 18 displayed a lowered white blood cells (WBC toxicity and an ameliorated radiation pneumonia, respectively. Conclusion. Couse of Astragalus-containing Chinese herbal prescriptions and radiotherapy may benefit the patients with NSCLC via increasing the therapeutic effectiveness and reducing the toxicity of radiotherapy. To confirm the exact merits, further rigorously designed trials are warranted.

    We previously reported that sphere-forming non-small cell lung cancer (NSCLC) tumor-initiating cells (TICs) have an altered activation of DNA damage response- and repair proteins and are refractory to DNA-damaging treatments. We analyzed whether chromatin organization plays a role in the observed refractoriness. Bulk cells and TICs from the NSCLC H23 and H1299 cell lines were examined using cell viability, clonogenic survival, Western blot, short interfering RNA analysis, and micronucleus assay. NSCLC TICs displayed elevated heterochromatin markers trimethylated lysine 9 of histone H3 and heterochromatin protein 1γ relative to bulk cells and reduced cell viability upon histone deacetylase inhibition (HDACi). Vorinostat and trichostatin A increased the euchromatin markers acetylated lysine 9/14 of histone H3 and lysine 8 of histone H4, and HDACi pretreatment increased the phosphorylation of the DNA damage response proteins ataxia telangiectasia mutated and DNA-dependent protein kinase, catalytic subunit, upon irradiation in TICs. HDACi sensitized TICs to cisplatin and to some extent to ionizing irradiation. The protectiveness of a dense chromatin structure was indicated by an enhanced frequency of micronuclei in TICs following irradiation, after knockdown of heterochromatin protein 1γ. Although confirmatory studies in additional NSCLC model systems and with respect to analyses of other DNA damage response proteins are needed, our data point toward a heterochromatic structure of NSCLC TICs, such that HDACi can sensitize TICs to DNA damage.

    Next-generation sequencing (NGS) is a cost-effective technology capable of screening several genes simultaneously; however, its application in a clinical context requires an established workflow to acquire reliable sequencing results. Here, we report an optimized NGS workflow analyzing 22 lung cancer-related genes to sequence critical samples such as DNA from formalin-fixed paraffin-embedded (FFPE) blocks and circulating free DNA (cfDNA). Snap frozen and matched FFPE gDNA from 12 non-small cell lung cancer (NSCLC) patients, whose gDNA fragmentation status was previously evaluated using a multiplex PCR-based quality control, were successfully sequenced with Ion Torrent PGM™. The robust bioinformatic pipeline allowed us to correctly call both Single Nucleotide Variants (SNVs) and indels with a detection limit of 5%, achieving 100% specificity and 96% sensitivity. This workflow was also validated in 13 FFPE NSCLC biopsies. Furthermore, a specific protocol for low input gDNA capable of producing good sequencing data with high coverage, high uniformity, and a low error rate was also optimized. In conclusion, we demonstrate the feasibility of obtaining gDNA from FFPE samples suitable for NGS by performing appropriate quality controls. The optimized workflow, capable of screening low input gDNA, highlights NGS as a potential tool in the detection, disease monitoring, and treatment of NSCLC.

    Full Text Available Ruilin Xue,1 Cuili Yang,1 Fang Zhao,2 Dejia Li1 1Global Health Institute, School of Public Health, 2Zhongnan Hospital, Wuhan University, Wuhan, People's Republic of ChinaAbstract: Aberrant methylation of CpG dinucleotides is a commonly observed epigenetic modification in human cancer. Thus, detection of aberrant gene promoter methylation as a tool for diagnosis of tumors or as a prognostic marker has been widely described for many types of cancers, including nonsmall cell lung cancer (NSCLC. Emerging evidence indicates that CDH13 is a candidate tumor suppressor in several types of human tumors, including NSCLC. However, the correlation between CDH13 hypermethylation and clinicopathological characteristics of NSCLC remains unclear. In the current study, we conducted a systematic review and meta-analysis to quantitatively evaluate the effects of CDH13 hypermethylation on the incidence of NSCLC and clinicopathological characteristics. Final analysis of 803 NSCLC patients from eleven eligible studies was performed. CDH13 hypermethylation was observed to be significantly higher in NSCLC than in normal lung tissue, with the pooled odds ratio (OR from seven studies including 448 NSCLC and 345 normal lung tissue (OR, 7.85; 95% confidence interval, 5.12–12.03; P<0.00001. CDH13 hypermethylation was also associated with pathological types. The pooled OR was obtained from four studies, including 111 squamous cell carcinoma and 106 adenocarcinoma (OR, 0.35; 95% confidence interval, 0.19–0.66; P=0.001, which indicated that CDH13 hypermethylation plays a more important role in the pathogenesis of adenocarcinoma. NSCLC with CDH13 hypermethylation was found more frequently in poorly differentiated NSCLC patients. NSCLC patients with CDH13 hypermethylation had a lower survival rate than those without CDH13 hypermethylation. In addition, CDH13 mRNA high expression was found to correlate with better overall survival for all NSCLC patients followed for 20 years

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

    Purpose: Quantification of volume changes on CBCT during SBRT for NSCLC may provide a useful radiological marker for radiation response and adaptive treatment planning, but the reproducibility of CBCT volume delineation is a concern. This study is to quantify inter-scan/inter-observer variability in tumor volume delineation on CBCT. Methods: Twenty earlystage (stage I and II) NSCLC patients were included in this analysis. All patients were treated with SBRT with a median dose of 54 Gy in 3 to 5 fractions. Two physicians independently manually contoured the primary gross tumor volume on CBCTs taken immediately before SBRT treatment (Pre) and after the same SBRT treatment (Post). Absolute volume differences (AVD) were calculated between the Pre and Post CBCTs for a given treatment to quantify inter-scan variability, and then between the two observers for a given CBCT to quantify inter-observer variability. AVD was also normalized with respect to average volume to obtain relative volume differences (RVD). Bland-Altman approach was used to evaluate variability. All statistics were calculated with SAS version 9.4. Results: The 95% limit of agreement (mean ± 2SD) on AVD and RVD measurements between Pre and Post scans were −0.32cc to 0.32cc and −0.5% to 0.5% versus −1.9 cc to 1.8 cc and −15.9% to 15.3% for the two observers respectively. The 95% limit of agreement of AVD and RVD between the two observers were −3.3 cc to 2.3 cc and −42.4% to 28.2% respectively. The greatest variability in inter-scan RVD was observed with very small tumors (< 5 cc). Conclusion: Inter-scan variability in RVD is greatest with small tumors. Inter-observer variability was larger than inter-scan variability. The 95% limit of agreement for inter-observer and inter-scan variability (∼15–30%) helps define a threshold for clinically meaningful change in tumor volume to assess SBRT response, with larger thresholds needed for very small tumors.

    Three hundred patients with symptomatic, locally advanced or metastatic NSCLC not requiring immediate radiotherapy were enrolled into this randomized multicentre trial comparing gemcitabine + BSC vs BSC alone. Patients allocated gemcitabine received 1000 mg/m2 on days 1, 8 and 15 of a 28-day cycle, for a maximum of six cycles. The main aim of this trial was to compare patient assessment of a predefined subset of commonly reported symptoms (SS14) from the EORTC QLQ-C30 and LC13 scales. The primary end-points were defined as (1) the percentage change in mean SS14 score between baseline and 2 months and (2) the proportion of patients with a marked (> or = 25%) improvement in SS14 score between baseline and 2 months sustained for > or =4 weeks. The secondary objectives were to compare treatments with respect to overall survival, and multidimensional QL parameters. The treatment groups were balanced with regard to age, gender, Karnofsky performance status (KPS) and disease stage (40% had metastatic disease). The percentage change in mean SS14 score from baseline to 2 months was a 10% decrease (i.e. improvement) for gemcitabine plus BSC and a 1% increase (i.e. deterioration) for BSC alone (P = 0.113, two-sample t-test). A sustained (> or = 4 weeks) improvement (> or =25%) on SS14 was recorded in a significantly higher proportion of gemcitabine + BSC patients (22%) than in BSC alone patients (9%) (P = 0.0014, Pearson's chi-squared test). The QLQ-C30 and L13 subscales showed greater improvement in the gemcitabine plus BSC arm (in 11 domains) than in the BSC arm (one symptom item). There was greater deterioration in the BSC alone arm (six domains/items) than in the gemcitabine + BSC arm (three QL domains). Tumour response occurred in 19% (95% CI 13-27) of gemcitabine patients. There was no difference in overall survival: median 5.7 months (95% CI 4.6-7.6) for gemcitabine + BSC patients and 5.9 months (95% CI 5.0-7.9) (log-rank, P = 0.84) for BSC patients, and 1 -year

    The aims of this study are to analyze differences in survival between academic and non-academic hospitals and to provide insight into treatment patterns for non-small cell lung cancer (NSCLC). Results show the state of NSCLC survival and care in the Netherlands. The Netherlands Cancer Registry provided data on NSCLC survival for all Dutch hospitals. We used the Kaplan-Meier estimate to calculate median survival time by hospital type and a Cox proportional hazards model to estimate the relative risk of mortality (expressed as hazard ratios) for patients diagnosed in academic versus non-academic hospitals, with adjustment for age, gender, and tumor histology, and stratifying for disease stage. Data on treatment patterns in Dutch hospitals was obtained from 4 hospitals (2 academic, 2 non-academic). A random sample of patients diagnosed with NSCLC from January 2009 until January 2011 was identified through hospital databases. Data was obtained on patient characteristics, tumor characteristics, and treatments. The Cox proportional hazards model shows a significantly decreased hazard ratio of mortality for patients diagnosed in academic hospitals, as opposed to patients diagnosed in non-academic hospitals. This is specifically true for primary radiotherapy patients and patients who receive systemic treatment for non-metastasized NSCLC. Patients diagnosed in academic hospitals have better median overall survival than patients diagnosed in non-academic hospitals, especially for patients treated with radiotherapy, systemic treatment, or combinations. This difference may be caused by residual confounding since the estimates were not adjusted for performance status. A wide variety of surgical, radiotherapeutic, and systemic treatments is prescribed. Copyright © 2015 Elsevier Inc. All rights reserved.

    Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related deaths worldwide due to the limited availability of effective therapeutic options. For instance, there are no effective strategies for NSCLCs that harbor mutant KRAS, the most commonly mutated oncogene in NSCLC. Thus, our purpose was to make progress toward the generation of a novel therapeutic strategy for NSCLC. We characterized the effects of suppressing focal adhesion kinase (FAK) by RNA interference (RNAi), CRISPR/CAS9 gene editing or pharmacologic approaches in NSCLC cells and in tumor xenografts. In addition, we tested the effects of suppressing FAK in association with ionizing radiation (IR), a standard-of-care treatment modality. FAK is a critical requirement of mutant KRAS NSCLC cells. With functional experiments, we also found that, in mutant KRAS NSCLC cells, FAK inhibition resulted in persistent DNA damage and susceptibility to exposure to IR. Accordingly, administration of IR to FAK-null tumor xenografts causes a profound antitumor effect in vivo CONCLUSIONS: FAK is a novel regulator of DNA damage repair in mutant KRAS NSCLC and its pharmacologic inhibition leads to radiosensitizing effects that could be beneficial in cancer therapy. Our results provide a framework for the rationale clinical testing of FAK inhibitors in NSCLC patients. Clin Cancer Res; 22(23); 5851-63. ©2016 AACR. ©2016 American Association for Cancer Research.

    Although tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and its agonistic receptors have been identified as highly promising antitumor agents preferentially eliminating cancer cells with minimal damage, the emergence of TRAIL resistance in most cancers may contribute to therapeutic failure. Thus, there is an urgent need for new approaches to overcome TRAIL resistance. Gold nanoparticles (AuNPs) are one of the most promising nanomaterials that show immense antitumor potential via targeting various cellular and molecular processes; however, the effects of AuNPs on TRAIL sensitivity in cancer cells remain unclear. In this study, we found that AuNPs combined with TRAIL exhibited a greater potency in promoting apoptosis in non-small-cell lung cancer (NSCLC) cells compared with TRAIL alone, suggesting that AuNPs sensitize cancer cells to TRAIL. Further experiments demonstrated that the combination of TRAIL and AuNPs was more effective in causing excessive mitochondrial fragmentation in cancer cells accompanied by a dramatic increase in mitochondrial recruitment of dynamin-related protein 1 (Drp1), mitochondrial dysfunctions, and enhancement of autophagy induction. Small interfering RNA (siRNA) silencing of Drp1 or inhibition of autophagy could effectively alleviate apoptosis in cells exposed to TRAIL combined with AuNPs. In vivo studies revealed that AuNPs augmented TRAIL sensitivity in tumor-bearing mice. Our data indicated that AuNPs potentiate apoptotic response to TRAIL in NSCLC cells through Drp1-dependent mitochondrial fission, and TRAIL combined with AuNPs can be a potential chemotherapeutic strategy for the treatment of NSCLC.

Camargo Cancer Center, São Paulo, 3Department of Oncology, Clinical Research – UPCO, Hospital de Clínicas de Porto Alegre, Porto Alegre, Rio Grande do Sul, Brazil Abstract: Lung cancer persists throughout the world as a major cause of death. In 2014, data from the Brazilian National Cancer Institute (INCA estimated 16.400 new cases of lung cancer among men (second most common and 10.930 new cases among women (fourth most common. These data are consistent for all Brazilian regions and reflect the trends of cancer in the country over the last decade. Brazil is a continental country, the largest in Latin America and fifth in the world, with an estimated population of >200 million. Although the discrepancy in the national income between rich and poor has diminished in the last 2 decades, it is still huge. More than 75% of the Brazilian population do not have private health insurance and rely on the national health care system, where differences in standard of cancer care are evident. It is possible to point out differences from the recommendations of international guidelines in every step of the lung cancer care, from the diagnosis to the treatment of advanced disease. This review aims to describe and recognize these differences as a way to offer a real discussion for future modifications and action points toward delivery of better oncology care in our country.

  18. The tumor suppressor gene TUSC2 (FUS1 sensitizes NSCLC to the AKT inhibitor MK2206 in LKB1-dependent manner.

    Directory of Open Access Journals (Sweden)

    Jieru Meng

    Full Text Available TUSC2-defective gene expression is detected in the majority of lung cancers and is associated with worse overall survival. We analyzed the effects of TUSC2 re-expression on tumor cell sensitivity to the AKT inhibitor, MK2206, and explored their mutual signaling connections, in vitro and in vivo. TUSC2 transient expression in three LKB1-defective non-small cell lung cancer (NSCLC cell lines combined with MK2206 treatment resulted in increased repression of cell viability and colony formation, and increased apoptotic activity. In contrast, TUSC2 did not affect the response to MK2206 treatment for two LKB1-wild type NSCLC cell lines. In vivo, TUSC2 systemic delivery, by nanoparticle gene transfer, combined with MK2206 treatment markedly inhibited growth of tumors in a human LKB1-defective H322 lung cancer xenograft mouse model. Biochemical analysis showed that TUSC2 transient expression in LKB1-defective NSCLC cells significantly stimulated AMP-activated protein kinase (AMPK phosphorylation and enzymatic activity. More importantly, AMPK gene knockdown abrogated TUSC2-MK2206 cooperation, as evidenced by reduced sensitivity to the combined treatment. Together, TUSC2 re-expression and MK2206 treatment was more effective in inhibiting the phosphorylation and kinase activities of AKT and mTOR proteins than either single agent alone. In conclusion, these findings support the hypothesis that TUSC2 expression status is a biological variable that potentiates MK2206 sensitivity in LKB1-defective NSCLC cells, and identifies the AMPK/AKT/mTOR signaling axis as an important regulator of this activity.

    Full Text Available There are no adequate data to determine whether intensity-modulated radiotherapy (IMRT is superior to three-dimensional conformal radiotherapy (3DCRT in the treatment of non-small cell lung cancer (NSCLC. This meta-analysis was conducted to compare the clinical outcomes of IMRT and 3DCRT in the treatment of NSCLC.No exclusions were made based on types of study design. We performed a literature search in PubMed, EMBASE and the Cochrane library databases from their inceptions to April 30, 2015. The overall survival (OS and relative risk (RR of radiation pneumonitis and radiation oesophagitis were evaluated. Two authors independently assessed the methodological quality and extracted data. Publication bias was evaluated by funnel plot using Egger's test results.From the literature search, 10 retrospective studies were collected, and of those, 5 (12,896 patients were selected for OS analysis, 4 (981 patients were selected for radiation pneumonitis analysis, and 4 (1339 patients were selected for radiation oesophagitis analysis. Cox multivariate proportional hazards models revealed that 3DCRT and IMRT had similar OS (HR = 0.96, P = 0.477 but that IMRT reduced the incidence of grade 2 radiation pneumonitis (RR = 0.74, P = 0.009 and increased the incidence of grade 3 radiation oesophagitis (RR = 2.47, P = 0.000.OS of IMRT for NSCLC is not inferior to that of 3DCRT, but IMRT significantly reduces the risk of radiation pneumonitis and increases the risk of radiation oesophagitis compared to 3DCRT.

    Glutaminase 1 (GLS1) expression is increased in non-small cell lung cancer (NSCLC). GLS1 knockdown using siRNA or inhibition using bis-2-(5-phenylacetamido-1,3,4-thiadiazol-2-yl)ethyl sulfide (BPTES) induced cell cycle arrest with significant reduction of ATP level while levels of reactive oxygen species or glutathione were not affected in NSCLC cell lines. Recently we found that NSCLC significantly depends on cytosol NADH for ATP production. GLS1 remarkably contributes to ATP production through transferring cytosolic NADH into mitochondria via malate-aspartate shuttle by supply of glutamate in NSCLC. Regulation of malate-aspartate shuttle by knockdown or inhibition of glutamic-oxaloacetic transaminase 2 or malate dehydrogenase 2 mimicked GLS1 knockdown, which induced cell death with ATP reduction in NSCLC. Therefore, GLS1 inhibition induced cell cycle arrest with ATP depletion by glutamate reduction. Dual inhibition with BPTES and thymidylate synthase inhibitor, 5-fluorouracil (5-FU), elicits cell death synergistically through cell cycle arrest in NSCLC. A preclinical xenograft model of NSCLC showed remarkable anti-tumour effect synergistically in the BPTES and 5-FU dual therapy group.

    Non-small cell lung cancer (NSCLC) frequently presents in advanced stages. A significant proportion of those with reportedly good ECOG performance status (PS) fail to receive planned multidisciplinary team (MDT) treatment, often for functional reasons, but an objective decline in physical performance is not well described. Sarcopenia, or loss of muscle mass, is an integral part of cancer cachexia. However, changes in both muscle mass and physical performance may predate clinically overt cachexia, and may be present even with normal body mass index. Physical fitness for treatment is currently subjectively assessed by means of the PS score, which may be inadequate in predicting tolerance to treatment. This study aims to evaluate whether measuring physical performance and muscle mass at baseline in NSCLC patients, in addition to PS score, is able to predict commencement and successful completion of MDT-planned treatment. This is a prospective, single-centre exploratory study of NSCLC patients attending a Rapid Access Lung Cancer clinic. Baseline data collected are (methods in brackets): physical performance (Short Physical Performance Battery), muscle mass (bioelectrical impedance ± dual energy x-ray absorptiometry), patient and physician-assessed PS (ECOG and Karnofsky), nutritional status and presence of cachexia. Longitudinal data consists of receipt and completion of MDT treatment plan. The primary outcome measure is commencement of MDT-planned treatment, and important secondary outcomes include successful completion of treatment, length of stay in surgical patients, and risk of chemotherapy- and radiotherapy-related side effects. A more comprehensive assessment of phenotype, particularly with regards to physical performance and muscle mass, will provide additional discriminatory information of patients' fitness for treatment. If positive, this study has the potential to identify targets for early intervention in those who are at risk of deterioration. This will

    Evidence shows that older patients are discriminated against when it comes to cancer treatment. A pilot project was commissioned by the Department of Health in partnership with Macmillan Cancer Support and Age UK. The project involved staff, including nurses, from five cancer networks in England examining ways to improve care for this patient group. Drawing on approaches used in geriatric medicine, patients' needs in accessing treatment were explored by conducting assessments and, for example, providing taxis for hospital appointments and practical support from voluntary organisations. Challenges for nurses included lack of training in patient screening and the extra workload caused by the assessments. The report on the pilot project concluded that involving elderly care specialists and using comprehensive geriatric assessments were useful approaches in the care of older cancer patients.

    Introduction Stage III non-small cell lung cancer (NSCLC) and its possible multimodal therapy present a challenge to the responsible oncologist, chest surgeon and radiologist. The aim of the present retrospective study was to analyse and evaluate the treatment algorithm in our hospital for patients with stage III NSCLC (intention to treat). We compared an aggressive treatment regime with primary trimodal therapy (high dose radiochemotherapy and resection), independently of "multilevel" N2 or "single level" N3 status. These results were then compared with a historical group of our patients who solely received simultaneous radiochemotherapy (bimodal therapy). Materials and Methods Within the period of the study, 156 patients were diagnosed with stage III NSCLC and treated with trimodal therapy. The median age was 71 years. 103 patients (60%) were male, 53 (34%) female. In the group with bimodal therapy, 102 patients were evaluated. Results After radiological restaging and checking functional resectability, 90 patients (57.7%) in the trimodal therapy group received secondary resection, including 37 (41.1%) lobectomies/bilobectomies, 37 (41.1%) sleeve lobectomies, 13 (14.4%) pneumonectomies and 3 (3.3%) segmentectomies (for severely restricted pulmonary function). The median survival time in the trimodal therapy group was 535 days and in the bimodal group 388 days; this difference was not statistically significant (p = 0.1377). Finally the 5-year survival after actual therapy was performed ("as-treated trimodally" vs. "as-treated bimodally"). The median survival time was then 807 days for trimodal therapy and 427 days for bimodal therapy. Conclusion High dose neoadjuvant radiochemotherapy followed by secondary resection is still a valuable option for selected patients with stage III NSCLC. However, this retrospective analysis failed to find a statistically significant survival advantage for the "intention-to-treat" trimodal patients. Georg Thieme Verlag KG

    Patients with non-small-cell lung cancer (NSCLC) appear to gain particular benefit from treatment with epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitors (TKI) if their disease tests positive for EGFR activating mutations. Recently, several large, controlled, phase III studies have been published in NSCLC patients with EGFR mutation-positive tumours. Given the increased patient dataset now available, a comprehensive literature search for EGFR TKIs or chemotherapy in EGFR mutation-positive NSCLC was undertaken to update the results of a previously published pooled analysis. Pooling eligible progression-free survival (PFS) data from 27 erlotinib studies (n = 731), 54 gefitinib studies (n = 1802) and 20 chemotherapy studies (n = 984) provided median PFS values for each treatment. The pooled median PFS was: 12.4 months (95% accuracy intervals [AI] 11.6–13.4) for erlotinib-treated patients; 9.4 months (95% AI 9.0–9.8) for gefitinib-treated patients; and 5.6 months (95% AI 5.3–6.0) for chemotherapy. Both erlotinib and gefitinib resulted in significantly longer PFS than chemotherapy (permutation testing; P = 0.000 and P = 0.000, respectively). Data on more recent TKIs (afatinib, dacomitinib and icotinib) were insufficient at this time-point to carry out a pooled PFS analysis on these compounds. The results of this updated pooled analysis suggest a substantial clear PFS benefit of treating patients with EGFR mutation-positive NSCLC with erlotinib or gefitinib compared with chemotherapy.

    The increase in the number of cancer survivors, together with the improvement of their follow-up, lead to the frequent diagnosis of resectable non-small cell lung cancer (NSCLC) in patients with history of previous malignancy. We sought to analyse the outcomes of these patients. Patients undergoing surgical resection for NSCLC between January 1980 and December 2009 were retrospectively reviewed. For each patient, the presence of previous malignancy was noted, and classified into five groups: oro-pharyngeal cancer, lung cancer, haematopoietic malignancy, other organ malignancy, and more than two cancers. The overall population included 5846 patients. Among them, 1243 (21%) had a history of previous malignancy, of whom 383 (31%) presented with synchronous cancer. Patients with history of previous malignancy were more often female, older, with more adenocarcinomas, more limited disease, less pneumonectomies, but higher postoperative morbidity and mortality. Overall survival was worse in patients with a history of previous malignancy than in patients without (median, 5 and 10 year: 33 months, 34.3%, 17.8% versus 47 months, 44.6%, 28.8%). A history of previous malignancy impacted significantly the prognosis of patients operated on for limited NSCLC. However, only surgical resection led to improved long-term survival at 5 years.

    The presence of muscle mass depletion is associated with poor outcomes and survival in cancer. Alongside muscle mass, assessment of muscle strength or physical performance is essential for the diagnosis of sarcopenia. Non-small cell lung cancer (NSCLC) is a prevalent form of cancer with high mortality, and Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) is commonly used to assess patients' suitability for treatment. However, a significant proportion of patients with good PS are unable to complete multidisciplinary team (MDT)-planned treatment. Little is known about the ability of objective measurements of physical performance in predicting patients' ability to complete MDT-planned treatment and outcomes in NSCLC. We sought to establish whether physical performance, utilising the short physical performance battery (SPPB), alongside muscle mass measurements, was able to predict receipt and completion of MDT-planned treatment, with a focus on chemotherapy in NSCLC. Participants with NSCLC treated through a single lung cancer MDT and ECOG PS 0-2 were recruited and the following assessed: body composition [bioelectrical impedance (BIA) and whole body dual-energy X-ray absorptiometry (DXA) in a subset], physical performance (SPPB), PS and nutritional status. We recorded receipt and completion of chemotherapy, as well as any adverse effects, hospitalisations, and treatment delays. We included a total of 62 participants with NSCLC, and in 26 of these, the MDT-planned treatment was chemotherapy. Participants with earlier stage disease and weight loss of performance by SPPB is quick and simple to do in clinical settings and may give better indication of likely chemotherapy treatment course completion than muscle mass alone and ECOG PS. In turn, this may identify specific targets for early functional intervention and impact on MDT decision-making and prudent use of resources.

    The nature-based and nontoxic image makes application of unproven methods in oncology attractive in contrast to application of a mechanized scientific medicine. The application frequency of these treatments ranges from 10% to greater than 60%. Increasingly, the promoters try to create a scientific impression through a pseudologic cancer theory, a harmless diagnostic test, and a holistic treatment of every cancer. Of the big variety of unproven methods, which are summarized in 11 groups in this review, the following are discussed: anthroposophic and other mistletoe preparations; homeopathy; Maharishi Ayur-Veda; unproven anticancer diets; orthomolecular medicine, including ascorbic acid; and methods supposedly stimulating unspecific and specific defense mechanisms. In conclusion, physicians should beware of and have knowledge of currently used unproven cancer treatments for epidemiologic, social, economic, and scientific reasons.

    Non-small cell lung cancer (NSCLC) is one of the most deadly human cancers. MicroRNA-300 acts as both tumor promoter and suppressor in different types of cancer. Here, we try to identify the function of microRNA-300 in human NSCLC. We compared MicroRNA-300 levels between tumor tissues versus paired adjacent non-tumor lung tissues from NSCLC patients, and in NSCLC versus normal lung cell lines. Effects of microRNA-300 on cell proliferation, invasion and migration were examined in vitro, and on tumor growth in vivo using a xenograft mouse model. Potential mRNA targets of microRNA-300 were predicted and underlying mechanism was explored. MicroRNA-300 expression was lower in both NSCLC tissues and cell lines. Overexpression of microRNA-300 inhibited proliferation, invasion and migration of NSCLC cells in vitro, and tumor growth in vivo. MicroRNA-300 could directly bind to the 3'-UTR of hypoxia inducible factor-3 alpha (HIF3α) mRNA, and inhibit both its mRNA and protein expressions. Restoring HIF3α expression could rescue the inhibitory effects of microRNA-300 on tumorigenesis of NSCLC both in vitro and in vivo. MicroRNA-300 is a tumor suppressor microRNA in NSCLC by downregulating HIF3α expression. Both microRNA-300 and HIF3α may serve as potential therapeutic targets in NSCLC treatment.

    Non-small cell lung cancer (NSCLC) is the leading cause of death in smokers and the most common cause for cancer mortality in both males and females in the United States. Predisposition of this malignancy to distant metastasis leads to poor prognosis; therefore, it is urgent to discover novel therapeutic agents for metastatic NSCLC. The present study aimed to investigate the effects of actein treatment on NSCLC cell growth and migration. Cell viability assays demonstrated that administration of actein markedly inhibited NSCLC cell proliferation in a dose- and time-dependent manner. Transwell assays demonstrated that actein treatment suppressed cell migration and invasion in two NSCLC cell lines, A549 and 95D. Furthermore, treatment with actein remarkably increased the activities of caspase-3 and -9 in NSCLC cells. The protein expression levels of cytoplasmic BCL2 apoptosis regulator (Bcl-2) and BCL2 associated X (Bax) were markedly decreased, while the protein expression levels of mitochondrial Bax, caspase-3, -9 and cytochrome c were upregulated following actein treatment, as evidenced by western blot analysis. The present results demonstrated that actein inhibited cell proliferation and metastasis and promoted cell apoptosis in NSCLC cells, which indicated that actein administration might serve as a potential therapeutic strategy for the treatment of NSCLC in the clinic.

    Lung cancer is a heterogeneous, complex, and challenging disease to treat. With the arrival of genotyping and genomic profiling, our simple binary division of lung cancer into non-small-cell lung cancer (NSCLC) and small-cell lung cancer (SCLC) is no longer acceptable. In the past decade and with the advent of personalized medicine, multiple advances have been made in understanding the underlying biology and molecular mechanisms of lung cancer. Lung cancer is no longer considered a single disease entity and is now being subdivided into molecular subtypes with dedicated targeted and chemotherapeutic strategies. The concept of using information from a patient's tumor to make therapeutic and treatment decisions has revolutionized the landscape for cancer care and research in general.Management of non-small-cell lung cancer, in particular, has seen several of these advances, with the understanding of activating mutations in EGFR, fusion genes involving ALK, rearrangements in ROS-1, and ongoing research in targeted therapies for K-RAS and MET. The next era of personalized treatment for lung cancer will involve a comprehensive genomic characterization of adenocarcinoma, squamous-cell carcinoma, and small-cell carcinoma into various subtypes. Future directions will involve incorporation of molecular characteristics and next generation sequencing into screening strategies to improve early detection, while also having applications for joint treatment decision making in the clinics with patients and practitioners. Personalization of therapy will involve close collaboration between the laboratory and the clinic. Given the heterogeneity and complexity of lung cancer treatment with respect to histology, tumor stage, and genomic characterization, mind mapping has been developed as one of many tools which can assist physicians in this era of personalized medicine. We attempt to utilize the above tool throughout this chapter, while reviewing lung cancer epidemiology, lung cancer

    Data on the treatment of non-small cell lung cancer (NSCLC) in real-world clinical practice in Japan are limited. This large-scale, retrospective cohort study examined data on patients' characteristics and systemic therapies for advanced or recurrent NSCLC in routine practice in Japan. This study used an electronic health records-based database of health claims and Diagnosis Procedure Combination data from 215 consenting hospitals in Japan. Records from April 2008 to September 2015 were analyzed. Regimens were examined by histology, age, sex, and therapeutic line. Logistic regression analysis was performed to predict which clinical and demographic factors affected patients' probability of receiving first- or second-line therapy or completing first-line platinum-based chemotherapy. Among 16,413 patients, 67.9%, 39.2%, and 22.3% received first-, second-, and third-line systemic treatment, respectively. Treatment was more common in patients aged 75 years, treatment at a general (vs cancer-specific) hospital, worse scores on certain activities of daily living, presence of chronic pulmonary disease, worse Hugh-Jones classification, and positive smoking status. The likelihood of completing first-line platinum-based chemotherapy was increased with greater body mass index, better activities of daily living scores, absence of chronic pulmonary disease, and better Hugh-Jones classification. The likelihood of continuing with second-line therapy was decreased with older age and recurrence of NSCLC. Systemic treatment patterns for advanced or recurrent NSCLC in Japan were varied. Nearly 30% of all patients and approximately half of elderly patients did not receive systemic treatment. Treatment rates declined with subsequent therapeutic lines. Generally, guidelines were followed with first-line treatment administration, but not with second-line administration. These results underscore the need for better guideline adherence and more optimal treatment in and elderly patients and

    Soon after the discovery that viruses cause human disease, started the idea of using viruses to treat cancer. After the initial indiscriminate use, crude preparations of each novel virus in the early twentieth century, a second wave of virotherapy blossomed in the 60s with purified and selected viruses. Responses were rare and short-lived. Immune rejection of the oncolytic viruses was identified as the major problem and virotherapy was abandoned. During the past two decades virotherapy has re-emerged with engineered viruses, with a trend towards using them as tumor-debulking immunostimulatory agents combined with radio or chemotherapy. Currently, oncolytic Reovirus, Herpes, and Vaccinia virus are in late phase clinical trials. Despite the renewed hope, efficacy will require improving systemic tumor targeting, overcoming stroma barriers for virus spread, and selectively stimulating immune responses against tumor antigens but not against the virus. Virotherapy history, viruses, considerations for clinical trials, and hurdles are briefly overviewed.

    The increasing prevalence of distant metastases from non-small cell lung cancer (NSCLC) indicates an urgent need for novel therapeutic modalities. Brain metastasis is particularly common in NSCLC, with severe adverse effects on clinical prognosis. Although the molecular heterogeneity of NSCLC and availability of various targeted agents suggest personalized therapeutic approaches for such brain metastases, further development of appropriate preclinical models is needed to validate the strategies. We established patient-derived xenografts (PDX) using NSCLC brain metastasis surgical samples and elucidated their possible preclinical and clinical implications for personalized treatment. NSCLC brain metastases (n = 34) showed a significantly higher successful PDX establishment rate than primary specimens (n = 64; 74% vs. 23%). PDXs derived from NSCLC brain metastases recapitulated the pathologic, genetic, and functional properties of corresponding parental tumors. Furthermore, tumor spheres established in vitro from the xenografts under serum-free conditions maintained their in vivo brain metastatic potential. Differential phenotypic and molecular responses to 20 targeted agents could subsequently be screened in vitro using these NSCLC PDXs derived from brain metastases. Although PDX establishment from primary NSCLCs was significantly influenced by histologic subtype, clinical aggressiveness, and genetic alteration status, the brain metastases exhibited consistently adequate in vivo tumor take rate and in vitro tumor sphere formation capacity, regardless of clinical and molecular conditions. Therefore, PDXs from NSCLC brain metastases may better represent the heterogeneous advanced NSCLC population and could be utilized as preclinical models to meet unmet clinical needs such as drug screening for personalized treatments. ©2014 American Association for Cancer Research.

    Small-molecule tyrosine kinase inhibitors (TKIs) of the human epidermal growth factor receptor (HER) include the reversible epidermal growth factor receptor (EGFR/HER-1) inhibitors gefitinib and erlotinib. EGFR TKIs have demonstrated activity in the treatment of patients with non-small cell lung cancer (NSCLC) harboring activating EGFR mutations; however, multiple mechanisms of resistance limit the benefit of these drugs. Although resistance to EGFR TKIs can be intrinsic and correlated with molecular lesions such as in Kirsten rat sarcoma viral oncogene homolog (KRAS; generally observed in a wild-type EGFR background), acquired resistance to EGFR TKIs can evolve in the setting of activating EGFR mutations, such as in the case of EGFR T790M mutations. Several irreversible inhibitors that target multiple members of the HER family simultaneously are currently in clinical development for NSCLC and may have a role in the treatment of TKI-sensitive and TKI-resistant disease. These include PF00299804, an inhibitor of EGFR/HER-1, HER-2, and HER-4, and afatinib (BIBW 2992), an inhibitor of EGFR/HER-1, HER-2, and HER-4. Results of large, randomized trials of these agents may help to determine their potential for the treatment of NSCLC.

    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.

    Lung cancer is the leading cause of cancer-related deaths worldwide. Despite advancements and improvements in surgical and medical treatments, the survival rate of lung cancer patients remains frustratingly poor. Local control for early-stage nonsmall cell lung cancer (NSCLC) has dramatically improved over the last decades for both operable and inoperable patients. However, the molecular mechanisms of NSCLC invasion leading to regional and distant disease spread remain poorly understood. Here, we identify microRNA-224 (miR-224) to be significantly up-regulated in NSCLC tissues, particularly in resected NSCLC metastasis. Increased miR-224 expression promotes cell migration, invasion, and proliferation by directly targeting the tumor suppressors TNFα-induced protein 1 (TNFAIP1) and SMAD4. In concordance with in vitro studies, mouse xenograft studies validated that miR-224 functions as a potent oncogenic miRNA in NSCLC in vivo. Moreover, we found promoter hypomethylation and activated ERK signaling to be involved in the regulation of miR-224 expression in NSCLC. Up-regulated miR-224, thus, facilitates tumor progression by shifting the equilibrium of the partially antagonist functions of SMAD4 and TNFAIP1 toward enhanced invasion and growth in NSCLC. Our findings indicate that targeting miR-224 could be effective in the treatment of certain lung cancer patients. PMID:26187928

    Full Text Available BACKGROUND: Lung cancer causes approximately 1.2 million deaths per year worldwide, and non-small cell lung cancer (NSCLC represents 85% of all lung cancers. Understanding the molecular events in non-small cell lung cancer (NSCLC is essential to improve early diagnosis and treatment for this disease. METHODOLOGY AND PRINCIPAL FINDINGS: In an attempt to identify novel NSCLC related genes, we performed a genome-wide screening of chromosomal copy number changes affecting gene expression using microarray based comparative genomic hybridization and gene expression arrays on 32 radically resected tumor samples from stage I and II NSCLC patients. An integrative analysis tool was applied to determine whether chromosomal copy number affects gene expression. We identified a deletion on 14q32.2-33 as a common alteration in NSCLC (44%, which significantly influenced gene expression for HSP90, residing on 14q32. This deletion was correlated with better overall survival (P = 0.008, survival was also longer in patients whose tumors had low expression levels of HSP90. We extended the analysis to three independent validation sets of NSCLC patients, and confirmed low HSP90 expression to be related with longer overall survival (P = 0.003, P = 0.07 and P = 0.04. Furthermore, in vitro treatment with an HSP90 inhibitor had potent antiproliferative activity in NSCLC cell lines. CONCLUSIONS: We suggest that targeting HSP90 will have clinical impact for NSCLC patients.

    Recently, pemetrexed (PEM), a new generation antifolate, has been used for the treatment of patients with advanced non-squamous cell carcinoma (SQ) of non-small cell lung cancer (NSCLC) and malignant pleural mesothelioma (MPM). However, no useful markers for selecting appropriate candidates exist at present. Tumor specimens were collected from 5 lung non-SQ and 8 MPM patients who underwent surgery and received PEM. Real-time PCR and immunohistochemical (IHC) staining of the primary tumor were used to analyze the mRNA and protein expressions of thymidylate synthase (TS)/dihydrofolate reductase (DHFR), and glycinamide ribonucleotide formyltransferase (GARFT), and to compare the expression status and clinical outcomes. TS, DHFR, and GARFT mRNA levels had a median value of 2.39, 1.70, and 1.40 in non-SQ samples of NSCLC patients. The TS and DHFR protein levels had a mean total score of 2 and 4 in non-SQ of NSCLC patients. TS, DHFR, and GARFT mRNA levels had a median value of 5.55, 3.73, and 3.52 in MPM patients. TS and DHFR protein levels had a mean total expression score of 1 and 3 in MPM patients. No significant correlation was identified between the expression levels of TS/DPD/GARFT mRNA and clinical response for the non-SQ of NSCLC and MPM patients treated with PEM. TS, DHFR, and GARFT mRNA and protein expression may not be useful markers for predicting clinical response in Japanese patients with non-SQ of NSCLC and MPM. Further investigations are necessary in order to develop biomarkers to determine the clinical benefits of PEM treatment.

    The best treatment for elderly patients with advanced non-small-cell lung cancer (NSCLC) is still debated. To guide clinical management of these patients and suggest the priorities for clinical research in this field, an International Expert Panel met in Naples, Italy, on April 19 to 20, 2004. Results and conclusions based on a review of evidence available in the literature to date are presented in this article. A comprehensive geriatric assessment is recommended to better define prognosis and to predict tolerance to treatment. In the first randomized study dedicated to elderly NSCLC patients, single-agent vinorelbine showed superiority over supportive care alone, both in terms of survival and quality of life. In a large randomized trial, gemcitabine plus vinorelbine failed to show any advantage over either agent alone. Subset analyses suggest that the efficacy of platinum-based combination chemotherapy is similar in fit older and younger patients, with an acceptable increase in toxicity for elderly patients. These data should be interpreted cautiously because retrospective subgroup analyses are encumbered by selection bias; hence, randomized trials dedicated to platinum-based chemotherapy for nonselected elderly patients are warranted. Several promising biologic therapies are under investigation; however, with present data, target-based agents as first-line treatment for elderly NSCLC patients are not yet recommended. Clinical research, with trials specifically designed for elderly patients, is mandatory. With the current evidence, single-agent chemotherapy with a third-generation drug (vinorelbine, gemcitabine, a taxane) should be the recommended option for nonselected elderly patients with advanced NSCLC. Platinum-based chemotherapy is a viable option for fit patients with adequate organ function. Best supportive care remains important, in addition to chemotherapy or as the exclusive option for patients who are unsuitable for more aggressive treatment.

    Non-small cell lung cancer (NSCLC) is the most common lung cancer type and the most common cause of mortality in lung cancer patients. NSCLC is often associated with resistance to chemotherapeutics and together with rapid metastatic spread, results in limited treatment options and poor patient survival. NSCLCs are heterogeneous, and consist of epithelial and mesenchymal NSCLC cells. Mesenchymal NSCLC cells are thought to be responsible for the chemoresistance phenotype, but if and how this phenotype can be transferred to other NSCLC cells is currently not known. We hypothesised that small extracellular vesicles, exosomes, secreted by mesenchymal NSCLC cells could potentially transfer the chemoresistance phenotype to surrounding epithelial NSCLC cells. To explore this possibility, we used a unique human bronchial epithelial cell (HBEC) model in which the parental cells were transformed from an epithelial to mesenchymal phenotype by introducing oncogenic alterations common in NSCLC. We found that exosomes derived from the oncogenically transformed, mesenchymal HBECs could transfer chemoresistance to the parental, epithelial HBECs and increase ZEB1 mRNA, a master EMT transcription factor, in the recipient cells. Additionally, we demonstrate that exosomes from mesenchymal, but not epithelial HBECs contain the ZEB1 mRNA, thereby providing a potential mechanism for the induction of a mesenchymal phenotype in recipient cells. Together, this work demonstrates for the first time that exosomes derived from mesenchymal, oncogenically transformed lung cells can transfer chemoresistance and mesenchymal phenotypes to recipient cells, likely via the transfer of ZEB1 mRNA in exosomes. © 2017 UICC.

    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.

Currently, platinum-based chemotherapy drugs, including cisplatin and carboplatin, are the most effective treatment for NSCLC. However, the clinical efficacy of chemotherapy is markedly reduced later in the treatment because drug resistance develops during the treatment. Recently, a series of studies has suggested the involvement of FAT10 in the development and malignancy of multiple cancer types. In this study, we focused our research on the function of FAT10 in NSCLC, which has not been previously reported in the literature. We found that the expression levels of FAT10 were elevated in quick chemoresistance NSCLC tissues, and we demonstrated that FAT10 promotes NSCLC cell proliferation, migration, and invasion. Furthermore, the protein levels of FAT10 were elevated in cisplatin- and carboplatin-resistant NSCLC cells, and knockdown of FAT10 reduced the drug resistance of NSCLC cells. In addition, we gained evidence that FAT10 regulates NSCLC malignancy and drug resistance by modulating the activity of the nuclear factor kappa B signaling pathway.

    The vascular endothelial growth factor (VEGF) and receptor is a therapeutic target because of the importance of this pathway in carcinogenesis. This pathway regulates and promotes angiogenesis as well as increases endothelial cell proliferation, permeability, and cancer survival. Ramucirumab is a new fully human monoclonal antibody that targets the VEGF receptor-2, an important key receptor implicated in angiogenesis. Ramucirumab has been approved for the treatment of second-line advanced or metastatic non-small cell lung cancer (NSCLC) in combination with the chemotherapy agent docetaxel. This was based on the result of the randomized trial REVEL of 1,253 patients with metastatic NSCLC previously treated with a platinum-based combination therapy. The authors observed a significant improvement in overall survival (OS) with an acceptable toxicities profile. In this study, patients were randomized to receive ramucirumab plus docetaxel or placebo with docetaxel. The combination of docetaxel and ramucirumab showed an improved OS (hazard ratio [HR]: 0.86; 95% CI: 0.75, 0.98). Median OS was 10.5 months in the ramucirumab arm versus 9.1 months in the placebo arm. Regarding side effects, the toxicity described on the ramucirumab arm were principally diarrhea, fatigue, and neutropenia. The most common (5%) adverse reactions of grade 3 and 4 in the ramucirumab arm were fatigue, neutropenia, febrile neutropenia, leukopenia, and hypertension. Adding ramucirumab to docetaxel improves QoL of patients, and does not impair symptoms or functioning. There are currently several trials in progress evaluating the effects of ramucirumab in combination with other drugs in patients with advanced NSCLC.

    Full Text Available AIM: To explore the association between genetic polymorphisms of the receptor for advanced glycation end-products (RAGE and susceptibility, chemotherapy response rate and prognosis of non-small cell lung cancer (NSCLC. METHOD: This is a prospective study in which 562 patients with NSCLC and 764 healthy controls were enrolled. Three RAGE genetic polymorphisms, namely, -429T/C, -374T/A and 82G/S were genotyped. Platinum-based chemotherapy was given to 432 subjects with advanced inoperable NSCLC and their responses to chemotherapy were evaluated. RESULTS: All the polymorphic genotypes of RAGE polymorphisms were associated with susceptibility for NSCLC. Only the 82G/S polymorphisms denoted a significant difference between responders and non-responders to chemotherapy. The 82SS genotype and 82S allele distribution not only increased the NSCLC risk, but also was associated with a lower chemotherapy response rate and poor prognosis, indicated by overall survival and progression free survival. CONCLUSION: The 82G/S genetic polymorphism of RAGE gene might be used as a genetic marker to screen for patients sensitive to thermotherapy and to predict the prognosis of NSCLC.

    Mohammed, Somala; Van Buren, George; Fisher, William E

    2014-07-28

    Pancreatic cancer is a leading cause of cancer mortality and the incidence of this disease is expected to continue increasing. While patients with pancreatic cancer have traditionally faced a dismal prognosis, over the past several years various advances in diagnosis and treatment have begun to positively impact this disease. Identification of effective combinations of existing chemotherapeutic agents, such as the FOLFIRINOX and the gemcitabine + nab-paclitaxel regimen, has improved survival for selected patients although concerns regarding their toxicity profiles remain. A better understanding of pancreatic carcinogenesis has identified several pre-malignant precursor lesions, such as pancreatic intraepithelial neoplasias, intraductal papillary mucinous neoplasms, and cystic neoplasms. Imaging technology has also evolved dramatically so as to allow early detection of these lesions and thereby facilitate earlier management. Surgery remains a cornerstone of treatment for patients with resectable pancreatic tumors, and advances in surgical technique have allowed patients to undergo resection with decreasing perioperative morbidity and mortality. Surgery has also become feasible in selected patients with borderline resectable tumors as a result of neoadjuvant therapy. Furthermore, pancreatectomy involving vascular reconstruction and pancreatectomy with minimally invasive techniques have demonstrated safety without significantly compromising oncologic outcomes. Lastly, a deeper understanding of molecular aberrations contributing to the development of pancreatic cancer shows promise for future development of more targeted and safe therapeutic agents.

    Two therapies are appropriate as 2nd-line treatment of non-small cell lung cancer (NSCLC) patients: chemotherapy and epidermal growth factor receptor (EGFR) inhibitor therapy. VeriStrat, a serum proteomic test, can be used to guide treatment decisions for NSCLC patients. The test classifies patients as likely to benefit from either of these two treatment options. The objective of this research was to model the anticipated survival and cost-effectiveness of four different treatment strategies: chemotherapy for all patients (C-all), EGFR inhibitor for all (E-all), a performance status guided selection strategy (PS-guided), and a strategy guided by VeriStrat test results (V-guided). We developed a Markov model with the perspective of the U.S. health care system. Model inputs were taken from published literature for the base-case analysis. One-way and probabilistic sensitivity analyses were performed. The C-all treatment strategy showed the best overall survival outcome (10.1 months), followed by V-guided (9.6 months), PS-guided (9.2 months), and E-all (8.2 months) strategies. The incremental cost-effectiveness ratio (ICER) of a V-guided treatment strategy was $91,111 (vs. E-all) and $8462 (vs. PS-guided) per quality-adjusted life year (QALY). The ICER for C-all compared to V-guided was $105,616. This cost-utility analysis indicates that a treatment strategy guided by the VeriStrat test in patients receiving second-line therapy for NSCLC may experience an overall survival benefit at an incremental cost-effectiveness ratio that is reasonable when compared with other practices, including cancer treatments, generally covered in the U.S. health care system. However, treating all patients with chemotherapy yielded the greatest expected survival. Copyright © 2013. Published by Elsevier Ireland Ltd.

    A number of studies on the relationship between xeroderma pigmentosum group G (XPG) polymorphisms and clinical outcomes in non-small cell cancer (NSCLC) have led to inconclusive results. This meta-analysis evaluates the predictive value of XPG polymorphisms on the treatment response rate and overall survival of patients with NSCLC. To measure the correlative strength of the relationship between XPG polymorphisms and outcomes of patients with NSCLC, we searched electronic databases, including PubMed and China National Knowledge Infrastructure, to retrieve studies up to August 2016. We also employed pooled odds ratios (ORs) and hazard ratios (HRs) corresponding to 95% confidence intervals (95% CIs). Twelve studies involving 2877 patients with NSCLC were included: 8 studies involving 1473 patients examined the correlation between XPG polymorphisms and tumor response rate and 7 studies involving 2329 patients reported on the correlation of XPG polymorphisms with overall survival. None of the XPG His1104Asp(C>G)/His46His(C>T) polymorphisms exhibited a correlation with treatment response rate or overall survival. However, in a further stratified analysis by ethnicity, carriers of the 1104G allele were associated with good response among Asians in the homozygote model (GG vs. CC: OR = 1.57, 95% CI: 1.05-2.34, P = 0.027). Meanwhile, further stratified by ethnicity, His46His polymorphism was not associated with RR and OS in any genetic models. No strong evidence was found to support the use of XPG polymorphisms as tumor response and prognostic factors of patients with NSCLC receiving a platinum-based treatment regimen, which is attributed to marginal association. Studies with large-scale and multiple ethnicities need to be conducted to verify the conclusion.

    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 a pivotal drug when a combination maintenance therapy is used in practice. For future maintenance therapy, we need to explore reliable predictive selection or exclusion markers that can predict who will really benefit from maintenance therapy.

    In many countries of the developed world, there is an increasing trend toward delay in childbearing from 30 to 40 years of age for various reasons. This is unfortunately concordant with an increasing incidence of breast cancer in women who have not yet completed their family. The current choice for premenopausal women with breast cancer is adjuvant therapy which includes cytotoxic chemotherapy, ovarian ablation (by surgery, irradiation, or chemical ovarian suppression), anti-estrogen therapy, or any combination of these. Although the use of adjuvant therapies with cytotoxic drugs can significantly reduce mortality, it raises issues of the long-term toxicity, such as induction of an early menopause and fertility impairment. The risk of infertility is a potential hardship to be faced by the patients following treatment of breast cancer. The offspring of patients who became pregnant after completion of chemotherapy have shown no adverse effects and congenital anomalies from the treatment, but sometimes high rates of abortion (29%) and premature deliveries with low birth weight (40%) have been demonstrated. Therefore, the issue of recent cytotoxic treatment remains controversial and further research is required to define a "safety period" between cessation of treatment and pregnancy. Preservation of fertility in breast cancer survivors of reproductive age has become an important issue regarding the quality of life. Currently, there are several potential options, including all available assisted technologies, such as in vitro fertilization and embryo transfer, in vitro maturation, oocyte and embryo cryopreservation, and cryopreservation of ovarian tissue. Because increased estrogen levels are thought to be potentially risky in breast cancer patients, recently developed ovarian stimulation protocols with the aromatase inhibitor letrozole and tamoxifen appear to provide safe stimulation with endogenous estrogen. Embryo cryopreservation seems to be the most established

    Although lung cancer is the leading cause of cancer death in women, few studies have investigated the hormonal influence on survival after a lung cancer diagnosis and results have been inconsistent. We evaluated the role of reproductive and hormonal factors in predicting overall survival in women with non-small-cell lung cancer (NSCLC). Population-based lung cancer cases diagnosed between November 1, 2001 and October 31, 2005 were identified through the Metropolitan Detroit Surveillance, Epidemiology, and End Results Registry. Interview and follow-up data were collected for 485 women. Cox proportional hazard regression models were used to determine hazard ratios (HRs) for death after an NSCLC diagnosis associated with reproductive and hormonal variables. Use of hormone therapy (HT) was associated with improved survival (HR, 0.69; 95% confidence interval, 0.54-0.89), adjusting for stage, surgery, radiation, education level, pack-years of smoking, age at diagnosis, race, and a multiplicative interaction between stage and radiation. No other reproductive or hormonal factor was associated with survival after an NSCLC diagnosis. Increased duration of HT use before the lung cancer diagnosis (132 months or longer) was associated with improved survival (HR, 0.54; 95% confidence interval, 0.37-0.78), and this finding remained significant in women taking either estrogen alone or progesterone plus estrogen, never smokers, and smokers. These findings suggest that HT use, in particular use of estrogen plus progesterone, and long-term HT use are associated with improved survival of NSCLC.

    Non-small cell lung cancer (NSCLC) is hyposensitive to the normal first and second-line chemotherapy regimens. Camptothecin derivative is becoming a hot point in the treatment of advanced NSCLC. The objective of this article was to evaluate the response, toxicity, and survival time of HMVP, MVP, and HVP regimens (detail in below) in the treatment of advanced NSCLC. A total of 134 cases with advanced NSCLC was randomized into three groups: HMVP group [46 patients, hydroxycamptothecin (HCPT) 12 mg/m(2) from d1 to d5, mitomycin C (MMC) 6 mg/m(2) d1, vindesine (VDS) 2.5-3 mg/m(2) d1 and d8, cisplatin (DDP) 50 mg/m(2) d2 and d3], MVP group (44 patients, MMC, VDS and DDP were the same as HMVP group) and HVP group (44 patients, HCPT, VDS, DDP were the same as HMVP group). The response rates were 39.54% (17/43), 35.57% (15/42), and 26.19% (11/42) in HMVP, MVP, and HVP groups, respectively; no significant difference was detected among the three groups (P >0.05). No significant difference was detected in the median time of remission, median survival time, and 1-, 2-year survival rates among the three groups. Moreover, no significant difference was detected in grade III-IV leukopenia, grade III-IV thrombocytopenia, grade III-IV nausea and vomiting and grade III-IV constipation among the three groups. The response rate of MVP regimen is slightly lower than that of HMVP regimen, but HMVP regimen do not show obvious superiority. It may increase toxicities such as leukopenia, nausea/vomiting, and constipation. The response rate of HVP regimen is slightly lower than that of MVP regimen.

    Full Text Available Ashwin Somasundaram, Timothy F Burns Division of Hematology/Oncology, Department of Medicine, University of Pittsburgh Cancer Institute, Pittsburgh, PA, USA Abstract: Lung cancer is the leading killer of both men and women in the US, and the 5-year survival remains poor. However, the approval of checkpoint blockade immunotherapy has shifted the treatment paradigm and provides hope for improved survival. The ability of non-small-cell lung cancer (NSCLC to evade the host immune system can be overcome by agents such as pembrolizumab (MK-3475/lambrolizumab, which is a monoclonal antibody targeting the programmed death 1 (PD-1 receptor. In early studies, treatment with pembrolizumab led to dramatic and durable responses in select patients (PD-L1+ tumors. This remarkable efficacy lead to approval of pembrolizumab in the second-line setting as response rates were almost doubled compared to standard of care (SOC chemotherapy. Most recently, data in the first-line setting from the KEYNOTE-024 study have redefined the SOC therapy for a selected subset of patients. In patients with ≥50% PD-L1+ tumors, pembrolizumab had a clear progression-free survival and overall survival benefit. Toxicity was mostly immune related and similar to checkpoint blockade toxicities observed in previous studies. The initial approval and subsequent studies of pembrolizumab required and utilized a companion diagnostic test, Dako’s IHC 22C3, to assess PD-L1 status of patients. The evaluation and scoring system of this assay has been used by other companies as a reference to develop their own assays, which may complicate selection of patients. Finally, the impact of pembrolizumab in NSCLC is growing as evidenced by the numerous, ongoing trials open for combinations with chemotherapy, chemoradiation, other immunotherapeutics, immunomodulators, tyrosine kinase inhibitors, PI3K inhibitors, MEK inhibitors, hypomethylating agents, and histone deacetylase inhibitors.

    Currently, no markers predictive of response to nivolumab monotherapy in patients with advanced non-small cell lung cancer (NSCLC) are currently recognized in Japan. The present study was undertaken to identify such markers. Medical records of 50 patients with advanced NSCLC and treated with nivolumab monotherapy at Shizuoka Cancer Center between December 2015 and April 2016 were retrospectively reviewed. The parameters studied were age, sex, Eastern Cooperative Oncology Group performance status, smoking history, histological diagnosis, epidermal growth factor receptor or anaplastic lymphoma kinase status, therapeutic line of nivolumab, efficacy of treatment immediately before nivolumab monotherapy, and time since previous therapy. The objective response rate to nivolumab monotherapy was 18% [95% confidence interval (CI) 10-31]. Multivariate logistic regression identified "squamous histology" [odds ratio (OR) 0.00054; 95% CI 0-0.27] and "response to the treatment immediately before nivolumab monotherapy" (OR 0.0011; 95% CI 0-0.092) as independently associated with response to nivolumab monotherapy. "Response to the treatment immediately before nivolumab monotherapy" might be a predictive marker of response to nivolumab in patients with advanced NSCLC.

    Because of the poor results observed after platinum-based first-line chemotherapy, research on new strategies for second-line treatment of advanced non-small-cell lung cancer (NSCLC) is warranted. Current research focuses on the development of new agents and the assessment of a combination of therapies, especially those with different mechanisms of action. PM02734 (elisidepsin, Irvalec) is a compound related to Kahalalide F (KF), a moderately soluble marine product that belongs to a family of dehydro aminobutyric acid-containing peptides isolated from the herbivorous marine mollusk Elysia rufescens. Preclinical and clinical studies showed that KF induces strong cytotoxic activity against different solid tumors, including NSCLC, particularly in patients with squamous histology; in fact, almost 40% of patients treated in the second line were still alive at 1 year after beginning treatment with KF. Analysis of data collected during clinical development has revealed that KF has a predictable and manageable toxicity profile. The toxicities most commonly associated with KF are generally transient and mild or moderate. The absence of hematologic toxicity and cumulative toxic effects suggests that KF may be suitable for combination trials with other anticancer agents. The development of KF could stopped because of the unavailability of a natural source of the compound. PM02734 is a closely related derivative of KF with similar activity and characteristics. Herein, we summarize the studies of PM02734 and future clinical perspectives.

This pathway regulates and promotes angiogenesis as well as increases endothelial cell proliferation, permeability, and cancer survival. Ramucirumab is a new fully human monoclonal antibody that targets the VEGF receptor-2, an important key receptor implicated in angiogenesis. Ramucirumab has been approved for the treatment of second-line advanced or metastatic non-small cell lung cancer (NSCLC in combination with the chemotherapy agent docetaxel. This was based on the result of the randomized trial REVEL of 1,253 patients with metastatic NSCLC previously treated with a platinum-based combination therapy. The authors observed a significant improvement in overall survival (OS with an acceptable toxicities profile. In this study, patients were randomized to receive ramucirumab plus docetaxel or placebo with docetaxel. The combination of docetaxel and ramucirumab showed an improved OS (hazard ratio [HR]: 0.86; 95% CI: 0.75, 0.98. Median OS was 10.5 months in the ramucirumab arm versus 9.1 months in the placebo arm. Regarding side effects, the toxicity described on the ramucirumab arm were principally diarrhea, fatigue, and neutropenia. The most common (5% adverse reactions of grade 3 and 4 in the ramucirumab arm were fatigue, neutropenia, febrile neutropenia, leukopenia, and hypertension.

    1994-09-01

    The present paper is a comprehensive review of available data concerning the role of radiotherapy as an intended curative treatment in patients with non-small cell lung cancer (NSCL). The following issues are reviewed (1) optimal dose, (2) optimal fractionation, (3) optimal treatment planning, (4) clinical results in terms of single treatment and combined treatment with either surgery or chemotherapy. In resectable NSCLC high dose radiotherapy to small localized tumours gives a 5-year survival rate of 7-38%. It is concluded that this treatment modality is appropriate for certain selected patients who refuse to have surgery, who have medical contradications for surgery, or who are of old age. It is discussed whether the treatment should be split course, continuous, hypo-og hyperfraction. A total dose of 55 Gy must be given. CT scanning should be mandatory for optimal planning and therapy. The literature does not give a conclusive answer to whether preoperative or postoperative radiotherapy is indicated. The data indicate that patients with Stage III NSCLC will benefit from a combined treatment modality in terms of chemotherapy based on high dose cisplatinum and radiotherapy. The main conclusion of the review is that many areas with randomized controlled trials are needed in order to answer the critical issue of the role of radiotherapy in the treatment of NSCLS.

However, further investigations about ctDNA prognostic and predictive value are still needed, and conclusions from several studies were inconsistent.Experimental design: We performed capture-based targeted ultradeep sequencing on liquid biopsies from a cohort of 34 advanced Chinese non-small-cell lung cancer (NSCLC patients and analyzed the clinical use of ctDNA in this study.Results: On the basis of clinical characteristics of the 34 NSCLC patients, we found that brain metastasis correlated with shorter progression-free survival (PFS and is more prone to happen in younger patients. After ctDNA sequencing, we analyzed the prognostic value of baseline ctDNA. In osimertinib-treated group, high max allelic fraction (maxAF correlated with shorter PFS. But for the cohort of 34 patients, no correlation can be observed between maxAF and PFS. We also presented two cases to demonstrate the value of disease progression prediction by ctDNA, which can be detected earlier than clinical response.Conclusion: In this study, we demonstrated that ctDNA is a prognostic marker for evaluating treatment response and predicting recurrence in advanced NSCLC.

An alternative strategy used to prolong the duration of first-line treatment and extend survival in metastatic NSCLC is first-line maintenance therapy. Erlotinib was approved for first-line maintenance in a stable disease population following results from a randomized, controlled Phase III trial comparing erlotinib with best supportive care. We aimed to estimate the incremental cost-effectiveness of erlotinib 150 mg/day versus best supportive care when used as first-line maintenance therapy for patients with locally advanced or metastatic NSCLC and stable disease.Methods: An economic decision model was developed using patient-level data for progression-free survival and overall survival from the SATURN (SequentiAl Tarceva in UnResectable NSCLC study. An area under the curve model was developed; all patients entered the model in the progression-free survival health state and, after each month, moved to progression or death. A time horizon of 5 years was used. The model was conducted from the perspective of national health care payers in France, Germany, and Italy. Probabilistic sensitivity analyses were performed.Results: Treatment with erlotinib in first-line maintenance resulted in a mean life expectancy of 1.39 years in all countries

    Full Text Available Background and objective The efficacy of complete resection of the cancer for patients with stage IIIa non-small cell lung cancer (NSCLC is limited. Synthetic therapy is taken the lead in advocating at present. However, the value of post-operative radiotherapy is not still clear. The aim of this study is to evaluate the survival time and side effects of postoperative chemotherapy or chemoradiotherapy in the treatment of stage IIIa NSCLC. Methods Between December 2003 and June 2007, 52 cases that have completed followed-up data with stage IIIa of NSCLC received in the First Affiliated Hospital of Dalian Medical University. Twenty-three patients received postoperative chemoradiotherapy (group A and 29 patients received postoperative chemotherapy combined with radiotherapy (group B. Group A adopted platinum-based combination chemotherapy for 4-6 cycles. The chemotherapeutics included gemcitabine, vinorelbine and docetaxel. Group B used chemotherapy for 2-4 cycles and then received 3-dimensional conformal radiotherapy (3D-CRT. The prescribe dose of target volume was 50 Gy. The chemotherapy was same as for group A and needed 4 cycles in all. The impact of postoperative adjuvant treatment on survival and toxicity was observed in patients with stage IIIa NSCLC and the reason of disease progression was analyzed. Results The median survival was 32.5 months in group A and 31.9 months in group B (P=0.371. Progression-free survival extended about 6 months (P=0.044. The survival rate was 87% at 1 year, 0.1% at 2 year, 33% at 3 year for group A compared with 93%, 69%, 45% for group B. The major side effects were hematological and gastrointestinal toxicities, including nausea, vomiting and neutropenia. There was no significant difference in these toxicities between the two groups (P>0.05. Radioactiv esophageal infection occurred in 17.2% of the patients. Acute and late radioactive lung infection occurred in 13.8% and 27.6% of the patients. All these toxicities

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

    The standard treatment for locally advanced non-small cell lung cancer (LA NSCLC) includes surgery, radiotherapy, chemotherapy, or some combination of these modalities. Many clinical trials have been conducted in attempts to intensify treatment for LA NSCLC, but with little improvement. A therapeutic plateau had been reached, with no major progress in extending survival for patients with this disease. However, several recent trials of newer targeted therapies and immunotherapies may shed new light on potential therapeutic breakthroughs. The potential benefits from new targeted therapies and immunotherapies in combination with other forms of therapy for LA NSCLC are sufficiently striking as to change current treatment paradigms. Trials of these agents are moving forward from patients with advanced disease to those with earlier stage disease, and from palliative intent to curative intent, which may well revolutionize treatment strategies that have been considered standard over the past several decades. Future studies are needed to explore the role of targeted therapies and immunotherapies in combination with existing therapies for earlier stage disease and for frontline treatment, either as concurrent or perhaps neoadjuvant or adjuvant approaches.

    It is estimated that half of all patients with cancer eventually develop a syndrome of cachexia, with anorexia and a progressive loss of adipose tissue and skeletal muscle mass. Cancer cachexia is characterized by systemic inflammation, negative protein and energy balance, and an involuntary loss of lean body mass. It is an insidious syndrome that not only has a dramatic impact on patient quality of life, but also is associated with poor responses to chemotherapy and decreased survival. Cachexia is still largely an underestimated and untreated condition, despite the fact that multiple mechanisms are reported to be involved in its development, with a number of cytokines postulated to play a role in the etiology of the persistent catabolic state. Existing therapies for cachexia, including orexigenic appetite stimulants, focus on palliation of symptoms and reduction of the distress of patients and families rather than prolongation of life. Recent therapies for the cachectic syndrome involve a multidisciplinary approach. Combination therapy with diet modification and/or exercise has been added to novel pharmaceutical agents, such as Megestrol acetate, medroxyprogesterone, ghrelin, omega-3-fatty acid among others. These agents are reported to have improved survival rates as well as quality of life. In this review, we will discuss the emerging understanding of the mechanisms of cancer cachexia, the current treatment options including multidisciplinary combination therapies, as well an update on new and ongoing clinical trials.

    Full Text Available The rapidly expanding catalogue of human oncogenic mutations, coupled with difficulties in identifying the cellular targets of active compounds in phenotypic screens, has refocused drug discovery efforts on inhibitors of specific cellular proteins. This new ‘target-based’ approach has enjoyed some spectacular successes in several types of tumours, including non-small-cell lung cancer (NSCLC. Epidermal growth factor receptor (EGFR mutations occur in 17% of NSCLC patients, with notable response to single agent therapy. Unfortunately, all patients eventually develop acquired resistance to EGFR tyrosine kinase inhibitors (TKIs, while complete remission rate to EGFR TKIs monotherapy is low. Priming BIM, a proapoptotic signalling BH3-only protein, induces sensitivity to erlotinib [Tarceva®] in EGFR-mutant cell lines. Synthetic lethal approaches and pre-emptive therapies based on the initial expression of BIM may significantly improve treatment outcomes. EGFR mutations result in transient pro-death imbalance of survival and apoptotic signalling in response to EGFR inhibition. Src homology 2 domain-containing phosphatase 2 is essential to the balance between extracellular signal-regulated kinase, phosphoinositide- 3-kinase/protein kinase B and signal transducer and activator of transcription 3 activity. Furthermore, stromal hepatocyte growth factor confers EGFR TKI resistance and induces inter-receptor crosstalk with Ephrin Type-A receptor 2, CDCP1, AXL, and JAK1. A better understanding of the complex cancer molecular biology of EGFR mutant lung cancer is crucial for development of effective treatment and design of successful future clinical studies.

    Induction therapy induces degenerative changes of various degrees in both cancerous and non-cancerous cells of non-small cell lung cancer (NSCLC). The effect of induction therapy on histological characteristics, in particular the ratio of residual cancer cells to non-cancerous components, is unknown. Seventy-four NSCLC patients treated with induction therapy followed by surgery were enrolled. Residual cancer cells were identified using anti-pan-cytokeratin antibody (AE1/AE3). We analyzed and quantified the following three factors via digital image analysis; (1) the tumor area containing cancer cells and non-cancerous components (TA), (2) the total area of AE1/AE3 positive cancer cells (TACC), (3) the percentage of TACC to TA (%TACC). These factors were also analyzed in a matched control group (surgery alone, n = 80). The median TACC of the induction therapy group was significantly lower than that of the control group (p induction therapy group (5.9 %) was significantly lower than that of the control group (58.6 %) (p induction therapy group. Conversely, TACC had a strong positive correlation with %TACC in the induction therapy group (r = 0.95), but not in the control group. Unlike the control group, the smaller the total area of residual cancer cells, the higher residual tumor contained non-cancerous components in the induction group, which may be the characteristic histological feature of NSCLC after induction therapy.

    Lung cancer with the ALK rearrangement constitutes only a small fraction of patients with non-small cell lung cancer (NSCLC). However, in the era of molecular-targeted therapy, efficient patient selection is crucial for successful treatment. In this context, an effective method for EML4-ALK detection is necessary. We developed a new highly sensitive variant specific TaqMan based real time PCR assay applicable to RNA from formalin-fixed paraffin-embedded tissue (FFPE). This assay was used to analyze the EML4-ALK gene in 96 non-selected NSCLC specimens and compared with two other methods (end-point PCR and break-apart FISH). EML4-ALK was detected in 33/96 (34%) specimens using variant specific real time PCR, whereas in only 23/96 (24%) using end-point PCR. All real time PCR positive samples were confirmed with direct sequencing. A total of 46 specimens were subsequently analyzed by all three detection methods. Using variant specific real time PCR we identified EML4-ALK transcript in 17/46 (37%) specimens, using end-point PCR in 13/46 (28%) specimens and positive ALK rearrangement by FISH was detected in 8/46 (17.4%) specimens. Moreover, using variant specific real time PCR, 5 specimens showed more than one EML4-ALK variant simultaneously (in 2 cases the variants 1+3a+3b, in 2 specimens the variants 1+3a and in 1 specimen the variant 1+3b). In one case of 96 EML4-ALK fusion gene and EGFR mutation were detected. All simultaneous genetic variants were confirmed using end-point PCR and direct sequencing. Our variant specific real time PCR assay is highly sensitive, fast, financially acceptable, applicable to FFPE and seems to be a valuable tool for the rapid prescreening of NSCLC patients in clinical practice, so, that most patients able to benefit from targeted therapy could be identified.

    Long non-coding RNAs play an important role in tumorigenesis, hence, identification of cancer-associated lncRNAs and investigation of their biological functions and molecular mechanisms are important for understanding the development and progression of cancer. Recently, the downregulation of lncRNA MEG3 has been observed in various human cancers. However, its role in non-small cell lung cancer (NSCLC) is unknown. The aim of this study was to examine the expression pattern of MEG3 in NSCLC and to evaluate its biological role and clinical significance in tumor progression. Expression of MEG3 was analyzed in 44 NSCLC tissues and 7 NSCLC cell lines by qRT-PCR. Over-expression approaches were used to investigate the biological functions of MEG3 in NSCLC cells. Bisulfite sequencing was used to investigate DNA methylation on MEG3 expression. The effect of MEG3 on proliferation was evaluated by MTT and colony formation assays, and cell apoptosis was evaluated by Hoechst staining and Flow-cytometric analysis. NSCLC cells transfected with pCDNA-MEG3 were injection into nude mice to study the effect of MEG3 on tumorigenesis in vivo . Protein levels of MEG3 targets were determined by western blot analysis. Differences between groups were tested for significance using Student's t-test (two-tailed). MEG3 expression was decreased in non-small cell lung cancer (NSCLC) tumor tissues compared with normal tissues, and associated with advanced pathologic stage, and tumor size. Moreover, patients with lower levels of MEG3 expression had a relatively poor prognosis. Overexpression of MEG3 decreased NSCLC cells proliferation and induced apoptosis in vitro and impeded tumorigenesis in vivo. MDM2 and p53 protein levels were affected by MEG3 over-expression in vitro. Our findings indicate that MEG3 is significantly down-regulated in NSCLC tissues that could be affected by DNA methylation, and regulates NSCLC cell proliferation and apoptosis, partially via the activition of p53. Thus, MEG3

    In industrialized countries lung cancer is associated with highest mortality among carcinoma. Progression of the disease is associated with diminished tolerance for physical activities, aggravated dyspnea and lowering of life quality. The aim of study was the evaluation of blood gas, blood saturation and chosen parameters of spirometric examination in NSCLC patients undergoing chemotherapy and pulmonary rehabilitation. Analysis of capillary blood was done using RapidPoint 405 Siemens device. Spirometric examination was done using PNEUMO abcMED device. Forty-nine patients with inoperable NSCLC were subjected to the examination. This included 38 men and 11 women aged between 46-75 years (mean age 63 +/- 7.5 years) who were separated into two groups: group I--25 patients undergoing standard chemotherapy (group C); group II--24 patients undergoing standard chemotherapy and pulmonary rehabilitation (group CK). All patients were subjected to blood gas analysis, blood saturation analysis and spirometric examination twice, before and after first-line chemotherapy Increase of pO2 and SaO2 in blood, and FEV1 and FVC in spirometric examination was significantly higher in patients undergoing pulmonary rehabilitation and chemotherapy (group II) (p blood gas, blood saturation analysis and chosen parameters of spirometric analysis. Pulmonary rehabilitation in patients with lung cancer seems to be an important form of supplementary treatment.

    Curcumin (diferuloylmethane) is a phenolic compound present in turmeric and is ingested daily in many parts of the world. Curcumin has been reported to cause inhibition on proliferation and induction of apoptosis in many human cancer cell lines, including non-small cell lung cancer cells (NSCLC). However, the clinical application of curcumin is restricted by its low bioavailability. In this report, it was observed that combined treatment of a low dosage of curcumin (5-10 µM) with a low concentration (0.1-2.5 µM) of small molecule inhibitors, including AG1478, AG1024, PD173074, LY294002 and caffeic acid phenethyl ester (CAPE) increased the growth inhibition in two human NSCLC cell lines: A549 and H1299 cells. The observation suggested that combined treatment of a low dosage of curcumin with inhibitors against epidermal growth factor receptor (EGFR), insulin-like growth factor 1 (IGF-1R), fibroblast growth factors receptor (FGFR), phosphatidylinositol 3-kinases (PI3K) or NF-κB signaling pathway may be a potential adjuvant therapy beneficial to NSCLC patients.

    Gastric cancer is a malignant disease which has generally a very bad prognosis. The frequency of occurence of this disease in the population is dependent on the age and localisation. Most frequently, this disease has occured in Japan, China, countries of South Africa and Eastern Europe for a long time but men are more likely to suffer from this disease than women witha ratio of 2 : 1. We retrospectively evaluated the group of patients who had been treated in our complex oncology center in the course of five years We treated 572 patients with gastric cancer in five years period. 218 patients of the total number were admitted, 185 patients of all hospitalized patients were operated (85 %). 53 patients of our group of hospitalized patients underwent adjuvant oncology therapy (24 %). Overall, five-year survival was 18.4 % in our group, the median survival time was 12.9 months. Radical surgery is considered to be the only treatment modality which can lead to patient´s cure under optimal conditions. Complex care for patients with gastric carcinoma should be centralized in big centers. Personalized oncological treatment should be a way how to get better results (Tab. 2, Fig. 5, Ref. 14).

    Patients with a newly diagnosed non-small cell lung cancer (NSCLC) stage IIIB are offered chemoradiotherapy, as proposed by the current guidelines. This combination treatment is facilitated by the coexistence of corresponding departments in the same establishment. The geographical disparity of these health facilities influences patients' willingness to be treated and may influence their survival. This is an observational study that compares the survival of two groups of patients with NSCLC stage IIIB: those treated with chemoradiotherapy versus those treated only with chemotherapy. These two comparable groups were formed exclusively by patients' and/or their families' decisions. One hundred fifteen consecutive NSCLC stage IIIB patients were included in the study. All were hospitalized in the biggest Chest Disease Hospital in Athens and were offered sequential chemoradiotherapy. Only 54 patients opted for the proposed treatment, while 61 decided to be treated with chemotherapy only, denying continuing their treatment in another health care unit (radiotherapy). Their survival and related factors were analyzed. Mean overall survival was estimated 10 months (95% confidence interval [CI]: 7.96-12.04). Patients treated with chemoradiotherapy had almost double overall survival compared to those under chemotherapy (P = 0.001): 13.6 months (95% CI: 12.3-14.9) versus 7.5 (95% CI: 6.1-8.9). Patients aged ≤ 65 years (P < 0.001), smokers (P < 0.001), and those without a cancer history (P < 0.001) survived longer. The lack of a radiotherapy department in a hospital providing chemotherapy impedes the application of current guidelines advocating combined radiochemotherapy. When recommended radiotherapy after six chemo cycles, half of the patients are unwilling to be displaced and do not follow the recommendations. This has an impact on patient survival.

    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.

    A recent pooled analysis of randomized trials indicated significant improvement in overall survival from cisplatin-based adjuvant chemotherapy for non-small cell lung cancer (NSCLC), depending on disease stage (only in stages II and III) and PS (≤ 1). Post-operative radiotherapy (RT) is optional for pN2 tumours. To evaluate opinions and daily clinical practice of Italian Oncologists about adjuvant treatment of NSCLC, a 46-item questionnaire was delivered via e-mail. Seventy-eight physicians from 68 Centers (out of 98 contacted) returned their questionnaire. Seventy-four, 86, 94, and 78% of them give the indication for adjuvant chemotherapy for stage IIA, IIB, IIIA, and IIIB disease, respectively and 14% in stage IB disease. Stage, PS, and age are taken into consideration evaluating adjuvant approach by 97, 95 and 73%, respectively. Cisplatin-vinorelbine (64%) and cisplatin-gemcitabine (33%), for 4 cycles (81%), are the preferred regimens, while 32% use different regimens. Ninety-two percent indicate RT in pN2 disease and/or positive resection margins. Real Number of patients Needed to Treat (NNT) is probably not completely known/understood and/or used by physicians. A substantial adherence between clinical daily practice in Italy and scientific progresses is described in this paper, even with some discordances regarding the most appropriate adjuvant chemotherapy regimen.

    The selection of treatment for local recurrence in patients with non-small-cell lung cancer (NSCLC) depends on the possibility of performing a radical tumor resection, the patient's performance status, and cardiopulmonary efficiency. Compared with chemoradiotherapy, surgical treatment offers a greater chance of long-term survival, but results in completion pneumonectomy and is associated with a relatively high rate of complications. Aim of the study was to evaluate early and long-term results of surgery and conservative treatment (chemoradiotherapy) in patients with local NSCLC recurrence. Between 1998 and 2011, 1697 NSCLC patients underwent lobectomy or bilobectomy at the Department of Thoracic Surgery in Poznań. Among them, 137 patients (8.1%) were diagnosed with cancer recurrence; chemotherapy or chemoradiotherapy was provided to 116 patients; 21 patients (15.3%) were treated with completion pneumonectomy. The median time from primary surgery to recurrence was 13.4 months. No metastases to N2 lymph nodes were observed among the patients undergoing surgery; in 7 patients N1 lymph node metastases were confirmed. The rate of complications after surgery was significantly higher in comparison with conservative therapy (80.9% vs. 48.3%). Patients treated with surgery were most likely to suffer from complications associated with the circulatory system (80.9%), while hematologic complications were dominant in the group undergoing oncological treatment (41.4%). There were no perioperative deaths after completion pneumonectomy. The age of the patients was the only factor which significantly influenced the incidence of complications in both groups of patients. Analysis of the survival curves demonstrated statistically significant differences in survival between the groups treated with surgery, chemoradiotherapy, and chemotherapy (p = 0.00001). Five-year survival probability was significantly higher among patients treated surgically as compared to patients undergoing

    Breast cancer is one of the most common cancers diagnosed during pregnancy and its frequency is increasing as more women postpone their pregnancies to their thirties and forties. Breast cancer diagnosis during pregnancy and lactation is difficult and complex both for the patient and doctors. Delay in diagnosis is frequent and treatment modalities are difficult to accept for the pregnant women. The common treatment approach is surgery after diagnosis, chemotherapy after the first trimester and radiotherapy after delivery. Even though early stage breast cancers have similar prognosis, advanced stage breast cancers diagnosed during pregnancy and lactation have poorer prognosis than similar stage breast cancers diagnosed in non-pregnant women. Women who desire to become pregnant after treatment of breast cancer will have many conflicts. Although the most common concern is recurrence of breast cancer due to pregnancy, the studies conducted showed that pregnancy has no negative effect on breast cancer prognosis. In this review we search for the frequency of breast cancer during pregnancy, the histopathological findings, risk factor, diagnostic and treatment modalities. We reviewed the literature for evidence based findings to help consult the patients on the outcome of breast cancer diagnosed during pregnancy and lactation, and also inform the patients who desire to become pregnant after breast cancer according to current evidences.

    There is a concern for dose calculation in highly heterogenous environments such as the thorax region. This study compares the quality of treatment plans of peripheral non-small cell lung cancer (NSCLC) stereotactic body radiation therapy (SBRT) using 2 calculation algorithms, namely, Eclipse Anisotropic Analytical Algorithm (AAA) and Acuros External Beam (AXB), for 3-dimensional conformal radiation therapy (3DCRT) and volumetric-modulated arc therapy (VMAT). Four-dimensional computed tomography (4DCT) data from 20 anonymized patients were studied using Varian Eclipse planning system, AXB, and AAA version 10.0.28. A 3DCRT plan and a VMAT plan were generated using AAA and AXB with constant plan parameters for each patient. The prescription and dose constraints were benchmarked against Radiation Therapy Oncology Group (RTOG) 0915 protocol. Planning parameters of the plan were compared statistically using Mann-Whitney U tests. Results showed that 3DCRT and VMAT plans have a lower target coverage up to 8% when calculated using AXB as compared with AAA. The conformity index (CI) for AXB plans was 4.7% lower than AAA plans, but was closer to unity, which indicated better target conformity. AXB produced plans with global maximum doses which were, on average, 2% hotter than AAA plans. Both 3DCRT and VMAT plans were able to achieve D95%. VMAT plans were shown to be more conformal (CI = 1.01) and were at least 3.2% and 1.5% lower in terms of PTV maximum and mean dose, respectively. There was no statistically significant difference for doses received by organs at risk (OARs) regardless of calculation algorithms and treatment techniques. In general, the difference in tissue modeling for AXB and AAA algorithm is responsible for the dose distribution between the AXB and the AAA algorithms. The AXB VMAT plans could be used to benefit patients receiving peripheral NSCLC SBRT. Copyright © 2017 American Association of Medical Dosimetrists. Published by Elsevier Inc. All rights

    Full Text Available Human tumour xenografts in a nude rat model have consistently been used as an essential part of preclinical studies for anticancer drugs activity in human. Commonly, these animals receive whole body irradiation to assure immunosuppression. But whole body dose delivery might be inhomogeneous and the resulting incomplete bone marrow depletion may modify tumour behaviour. To improve irradiation-mediated immunosuppression of human non-small cell lung cancer (NSCLC xenografts in a nude rat model irradiation (2 + 2 Gy from opposite sides of animals has been performed using a conventional X-ray tube. The described modification of whole body irradiation improves growth properties of human NSCLC xenografts in a nude rat model. The design of the whole body irradiation mediated immunosuppression described here for NSCLC xenografts may be useful for research applications involving other types of human tumours.

    Full Text Available Lung adenocarcinoma is the most common subtype of non-small cell lung cancer (NSCLC. With the discovery of epidermal growth factor receptor (EGFR mutations, anaplastic lymphoma kinase (ALK rearrangements and effective targeted therapies, therapeutic options are expanding for patients with lung adenocarcinoma. Here, we review novel therapies in non-squamous NSCLC, which are directed against oncogenic targets, including EGFR, ALK, ROS1, BRAF, MET, human epidermal growth factor receptor 2 (HER2, vascular endothelial growth factor receptor 2 (VEGFR2, RET and NTRK. With the rapidly evolving molecular testing and development of new targeted agents, our ability to further personalize therapy in non-squamous NSCLC is rapidly expanding.

    The distribution and function of T lymphocytes in human lung cancer remain limited. In this study, we investigated the properties of human T cell subsets in the blood of non-small cell lung cancer (NSCLC) patients. We found a relatively normal level of CD4+ subsets in the blood of NSCLC patients, but CD8+ effector T cells increased and CD8+ effector memory cells declined compared to the healthy donors. To further analyze their properties, we stimulated the peripheral blood mononuclear cells (PBMCs) of NSCLC patients by mitogens to examine cytokine production. Our data suggest that both CD4+ and CD8+ naïve cells in NSCLC patients significantly reduced IFN-γ and TNF-α production. Additionally, fewer CD8+ effector cells produced IFN-γ and TNF-α in NSCLC patients than in healthy subjects. Moreover, similar results were observed for CD4+ or CD8+ memory cells in NSCLC patients for the production of IFN-γ, TNF-α, and IL-17. Therefore, our results strongly suggest that the function of CD4+ and CD8+ T lymphocytes in NSCLC patients is compromised or dysregulated. The development of vaccines and antitumor immunotherapy may be essential for the treatment of lung cancer patients.

    The aim was to evaluate stereotactic body radiation therapy (SBRT) treatment planning variability for early stage nonsmall cell lung cancer (NSCLC) with respect to the published guidelines of the Stereotactic Radiotherapy Working Group of the German Society for Radiation Oncology (DEGRO). Planning computed tomography (CT) scan and the structure sets (planning target volume, PTV; organs at risk, OARs) of 3 patients with early stage NSCLC were sent to 22 radiotherapy departments with SBRT experience: each department was asked to prepare a treatment plan according to the DEGRO guidelines. The prescription dose was 3 fractions of 15 Gy to the 65% isodose. In all, 87 plans were generated: 36 used intensity-modulated arc therapy (IMAT), 21 used three-dimensional conformal radiation therapy (3DCRT), 6 used static field intensity-modulated radiation therapy (SF-IMRT), 9 used helical radiotherapy and 15 used robotic radiosurgery. PTV dose coverage and simultaneously kept OARs doses were within the clinical limits published in the DEGRO guidelines. However, mean PTV dose (mean 58.0 Gy, range 52.8-66.4 Gy) and dose conformity indices (mean 0.75, range 0.60-1.00) varied between institutions and techniques (p ≤ 0.02). OARs doses varied substantially between institutions, but appeared to be technique independent (p = 0.21). All studied treatment techniques are well suited for SBRT of early stage NSCLC according to the DEGRO guidelines. Homogenization of SBRT practice in Germany is possible through the guidelines; however, detailed treatment plan characteristics varied between techniques and institutions and further homogenization is warranted in future studies and recommendations. Optimized treatment planning should always follow the ALARA (as low as reasonably achievable) principle. (orig.)

  12. [PARAMOUNT trial: clinical meaning of continuous maintenance therapy in lung cancer].

    2015-05-01

    Non-small cell lung cancer (NSCLC) remains one of the leading causes of cancer related deaths worldwide across both sex. Patients with Advanced -NSCLC (A-NSCLC) do not have curative treatment options, so the primary endpoint of every therapeutic decision aims to prolong survival, improving or maintain a good Quality of Life (QoL). Histology could represent a positive predictive factor for patients with Non squamous NSCLC (Nsq-NSCLC) respect to pemetrexed treatment. Pemetrexed is an antifolate that inhibits primarily thymidylate synthase (TS), together with dihydrofolate reductase and glycinamide ribonucleotide formyl transferase. Pemetrexed in combination with cisplatin is approved in the first line setting and as monotherapy in the switch or continuous maintenance of Non Squamous A-NSCLC. Maintenance therapy is a widely used therapeutic option in other solid and hematologic malignancies, but in the A-NSCLC represent an innovative approach. The rationale in this new setting of patients is based on the evidence that patients who benefit from an initial induction therapy platinum based may benefit from maintenance therapy with the third generation agent dropping the platinum drug after four to six cycles. We can define two types of maintenance therapy: continuation maintenance and switch maintenance. Major results in prolonging Overall Survival (OS) was reported with the continuation maintenance strategy as in the PARAMOUNT trial.

    Erlotinib and gefitinib are weak base drugs whose absorption and clinical efficacy may be impaired by concomitant gastric acid suppressive (AS) therapy, yet proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2As) are widely indicated in non-small cell lung cancer (NSCLC) patients for the prevention and treatment of erlotinib-induced gastrointestinal injury and corticosteroid-associated gastric irritation. We assessed the clinical relevance of this potential drug-drug interaction (DDI) in a retrospective cohort of EGFR-mutant NSCLC patients. The AS usage rate was 35%. In the overall cohort, AS users did not experience poorer OS (HR: 1.47, 95% CI: 0.92 - 2.35, P = 0.10; median, 11.4 versus 17.5 months) or PFS (HR = 1.37, 95% CI: 0.89 - 2.12, P = 0.16; median, 7.6 versus 8.7 months) compared with non-users in multivariate Cox regression analysis. However, subgroup analyses indicated that AS usage was associated with significantly poorer OS and PFS in patients who had fewer or milder comorbidities (Charlson comorbidity index ≤ 2), those with Karnofsky performance status < 90, and never-smokers. A retrospective database analysis of 157 patients given erlotinib or gefitinib for EGFR-mutant advanced NSCLC from two institutions was conducted. Patients were classified as AS-users if the periods of AS and anti-EGFR therapy overlapped by ≥ 30%. Overall survival (OS) and progression-free survival (PFS) were assessed according to AS usage. Concomitant AS therapy did not have an adverse impact on OS and/or PFS in the overall cohort. Our subgroup findings should be regarded exploratory and require replication in a large prospective cohort.

    Lung cancer is the leading cause of cancer-related death worldwide. Non-small cell lung cancer (NSCLC) accounts for 80% of lung cancer cases and the reported overall 5-year survival rate is less than 5%. Natural medicines have attracted much attention due to their lower toxicity and fewer side effects. Trichosanthes kirilowii Maxim (TKM) fruits are commonly used in cancer treatment in combination with other Chinese medicinal herbs. However, little is known about their biological functions and mechanisms in NSCLC cells. In this study, we investigated the efficacy of TKM fruits in NSCLC cells using cell proliferation, invasion, migration, and anchorage independent assays and a Xenograft NSCLC tumor model, and explored the possible biological mechanism by flow cytometric analysis, cDNA microarray and real-time PCR. Results showed that TKM fruits significantly suppressed NSCLC cell proliferation, migration, invasion, tumorigenicity and tumor growth, and significantly extended the survival time of NSCLC-bearing mice. Flow cytometric analysis showed that TKM fruits significantly induced G2-M arrest, necrosis and apoptosis in NSCLC cells. cDNA microarray analysis revealed that TKM fruits regulated the differential expression of 544 genes, and the differential expression of selected genes was also confirmed. Gene ontology (GO) analysis showed that 18 of first 20 biological processes were involved in cell cycle and mitosis. These results indicate that TKM fruits have certain inhibitory effect on NSCLC cells through cell-cycle and mitosis arrest, and suggest that TKM fruits may be an important resource for developing new antitumor drugs, and a potent natural product for treating patients with NSCLC.

    2006-06-01

    Full Text Available Non-small cell lung cancer (NSCLC is the most common type of lung cancer and its medical and economical burden represents a serious matter in Europe and Usa, due to its high mortality rates and drug costs. Lung cancer is responsible for about 30% of cancer death in men and women; in Europe only about 8 per cent of people with lung cancer survive for 5 years. At present combination chemotherapy based on cisplatin or carboplatin associated with paclitaxel, vinorelbine or gemcitabine is the state of the art for the treatment in patients with stage IIIb or IV NSCLC. Aim of this study was to compare the cost-effectiveness of paclitaxel/carboplatin (PCb, gemcitabine/cisplatin (GC and vinorelbine/cisplatin (VC in the perspective of the Italian National Health Service. Therefore we perfomed a semi-Markov decision model mainly based on clinical results from the Italian Lung Cancer Project. The model included differential direct medical costs registered for two years from starting chemotherapy, using tariffs valid for 2005. Benefits was measured by years of life saved (YOLs. The model also allowed to estimate only costs accrued over the period of time, performing a cost-minimisation analysis. According to cost-effectiveness analysis, VC is dominated because it’s more costly and less effective than GC. On the contrary, combination chemotherapy with GC is more inexpensive but less effective than paclitaxel/carboplatin (PCb: in this case we compared the incremental cost-effectiveness ratio (ICER with a maximum acceptable willingness-to-pay (WTP value. In the base scenario the ICER of PCb over GC treatment is 52,326 euro/ YOLs, which is definitely lower than the maximum acceptable WTP value. Sensitivity analyses confirmed the robustness of the results from cost-effectiveness analysis in the base scenario.

    Full Text Available Mark W Burns, Eric S Kim Wilmot Cancer Center, University of Rochester, Rochester, NY, USA Abstract: Lung cancer has become one of the leading causes of death in both men and women in the United States, with approximately 230,000 new cases and 160,000 deaths each year. Approximately 80% of lung cancer patients are diagnosed with non-small-cell lung cancer (NSCLC, a subset of epithelial lung cancers that are generally insensitive to chemotherapy. An estimated 3%–7% of NSCLC patients harbor tumors containing anaplastic lymphoma kinase (ALK gene rearrangement as an oncogenic driver. Subsequent development of the first-generation tyrosine kinase inhibitor crizotinib demonstrated substantial initial ALK+-tumor regression, yet ultimately displayed resistance in treated patients. The recently approved tyrosine kinase inhibitor ceritinib has been shown to be an effective antitumor agent against crizotinib-naïve and -resistant ALK+-NSCLC patients. In this review, we will provide an overview of biology and management of ALK+-NSCLC with a special focus on clinical development of ceritinib.

    Lung cancer leads the cause of cancer-related deaths in men and women around the world. The most common is non-small cell lung cancer (NSCLC). Fast and accurate staging is essential for choosing treatment for NSCLC. The positron emission tomography (PET) with {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) can provide molecular and metabolic information, which acquired simultaneously with computed tomography (CT), has proved to be a very useful tool in the cancer diagnosis and staging. Identifying the stage of lung cancer is important to avoid unnecessary surgeries, reducing morbidity and treatment costs. This study aims to examine the impact of {sup 18}F-FDG PET/CT in the initial evaluation of patients with NSCLC in the Brazilian reality. Twenty-six patients with histopathologic diagnosis of NSCLC were included. They underwent staging in two separated moments: first with morphological images (x-ray and computed tomography scan) and after with {sup 18}F-FDG PET/CT. The performance of {sup 18}F-FDG PET/CT changed lymph node staging in around 30% of the patients initially classified as potentially operable, with high sensitivity and negative predictive values. Regarding the stage of metastasis, {sup 18}F-FDG PET/CT increased by 11.5% the detection of metastasis not previously detected. About the clinical staging, using the {sup 1}'8F-FDG PET/CT significantly reduced the number of patients classified as potentially operable in the early stages, avoiding the use of unnecessary thoracotomies in 19.2% of patients. The metabolic information obtained by {sup 18}F-FDG PET/CT demonstrated better accuracy when compared to anatomic methods in the detection of lymph node and distant metastases. Thus, having important impact on therapeutic strategy and treatment cost related. (author)

    We evaluated the efficacy, toxicity, and dose responses of re-irradiation with stereotactic body radiotherapy (SBRT) in patients with recurrent non- small cell lung cancer (NSCLC) after previous irradiation. 28 patients were included. Previous median radiation doses were 54 and 66 Gy. The median interval time between previous radiotherapy and SBRT was 14 months. The median follow-up time after SBRT was 9 months (range 3-93 months). To evaluate the effectiveness of SBRT, local control, overall survival, and treatment-related toxicity were reported. SBRT doses and fractionation ranged from 60 to 30 Gy and from 3 to 8, respectively, according to previous doses, location of the recurrence, and interval time. 65% of tumor recurrences overlapped with previous treatment, while 35% of tumors recurred outside of the previous treatment. 4 patients had local progression after SBRT at their first follow-up. The Kaplan-Meier estimates of the 1- and 2-year actuarial overall survival were 71 and 42%, respectively. The mean survival following SBRT was 32.8 months, and the median survival was 21 months. No grade 3 or higher toxicities were observed. Robotic SBRT is a tolerable treatment option with manageable toxicity which can be used with radical or palliative intent in carefully selected patients with locally recurrent tumors after previous irradiation. © 2017 S.

    Concurrent chemoradiotherapy (CCRT) is considered the standard treatment regimen in non-surgical locally advanced non-small cell lung cancer (NSCLC) patients and sequential chemoradiotherapy (SCRT) is recommended in patients who are unfit to receive CCRT or when the treatment volume is considered too large. In this study, we investigated the proportion of CCRT/SCRT in the Netherlands and Belgium. Furthermore, patient and disease characteristics associated with SCRT were assessed. An observational study was carried out with data from three independent national registries: the Belgian Cancer Registry (BCR), the Netherlands Cancer Registry (NCR) and the Dutch Lung Cancer Audit-Radiotherapy (DLCA-R). Differences in patient and disease characteristics between CCRT and SCRT were tested with unpaired t-tests (for continuous variables) and with chi-square tests (for categorical variables). A prognostic model was constructed to determine patient and disease parameters predictive for the choice of SCRT. This study included 350 patients from the BCR, 780 patients from the NCR and 428 patients from the DLCA-R. More than half of the stage III NSCLC patients in the Netherlands (55%) and in Belgium more than a third (35%) were treated with CCRT. In both the Dutch and Belgian population, higher age and more advanced N-stage were significantly associated with SCRT. Performance score, pulmonary function, comorbidities and tumour volume were not associated with SCRT. In this observational population-based study, a large treatment variation in non-surgical stage III NSCLC patients was observed between and within the Netherlands and Belgium. Higher age and N-stage were significantly associated with the choice for SCRT. Copyright © 2017 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.

    In a population-based case-control study, we explored the associations between 42 polymorphisms in seven genes in this region and non-small cell lung cancer (NSCLC) risk among Caucasian (364 cases; 380 controls) and African American (95 cases; 103 controls) women. Two TERT region SNPs, rs2075786 and rs2853677, conferred an increased risk of developing NSCLC, especially among African American women, and TERT-rs2735940 was associated with a decreased risk of lung cancer among African Americans. Five of the 20 GHR polymorphisms and SEPP1-rs6413428 were associated with a marginally increased risk of NSCLC among Caucasians. Random forest analysis reinforced the importance of GHR among Caucasians and identified AMACR, TERT, and GHR among African Americans, which were also significant using gene-based risk scores. Smoking-SNP interactions were explored, and haplotypes in TERT and GHR associated with NSCLC risk were identified. The roles of TERT, GHR, AMACR and SEPP1 genes in lung carcinogenesis warrant further exploration.

    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.

    Rodriguez-Wallberg, Kenny A; Oktay, Kutluk

    2014-01-01

    The majority of children, adolescents, and young adults diagnosed with cancer today will become long-term survivors. The threat to fertility that cancer treatments pose to young patients cannot be prevented in many cases, and thus research into methods for fertility preservation is developing, aiming at offering cancer patients the ability to have biologically related children in the future. This paper discusses the current status of fertility preservation methods when infertility risks are related to surgical oncologic treatments, radiation therapy, or chemotherapy. Several scientific groups and societies have developed consensus documents and guidelines for fertility preservation. Decisions about fertility and imminent potentially gonadotoxic therapies must be made rapidly. Timely and complete information on the impact of cancer treatment on fertility and fertility preservation options should be presented to all patients when a cancer treatment is planned.

    Nintedanib (Vargatef®) is a triple angiokinase inhibitor that potently blocks the proangiogenic pathways mediated by vascular endothelial growth factor receptors, platelet-derived growth factor receptors and fibroblast growth factor receptors. In the EU, nintedanib in combination with docetaxel is indicated for adults with locally advanced, metastatic or locally recurrent non-small cell lung cancer (NSCLC) of adenocarcinoma tumour histology after first-line chemotherapy. Nintedanib in combination with docetaxel relative to placebo plus docetaxel significantly prolonged progression-free survival (PFS), but did not increase overall survival (OS), in the overall population of patients with advanced NSCLC in the phase III LUME-Lung 1 study. Notably, the subgroup of patients with adenocarcinoma histology experienced a significant improvement in both PFS and OS with nintedanib plus docetaxel, with a greater benefit seen in patients with rapidly progressing disease. Nintedanib is the first antiangiogenic agent to have shown a survival benefit in the second-line treatment of these patients. Health-related quality of life (HR-QOL) was not adversely affected with the addition of nintedanib to docetaxel in the overall population or in the adenocarcinoma subgroup. Nintedanib combination therapy had a generally manageable tolerability profile. Adverse events typically associated with antiangiogenic agents (e.g. bleeding and hypertension) were not greatly increased with nintedanib plus docetaxel relative to placebo plus docetaxel. To conclude, nintedanib in combination with docetaxel is an effective treatment option for patients with advanced NSCLC of adenocarcinoma histology after first-line chemotherapy.

    Cannabinoids, the active components of the hemp plant Cannabis sativa, along with their endogenous counterparts and synthetic derivatives, have elicited anti-cancer effects in many different in vitro and in vivo models of cancer. While the various cannabinoids have been examined in a variety of cancer models, recent studies have focused on the role of cannabinoid receptor agonists (both CB(1) and CB(2)) in the treatment of estrogen receptor-negative breast cancer. This review will summarize the anti-cancer properties of the cannabinoids, discuss their potential mechanisms of action, as well as explore controversies surrounding the results.

    Rash is a common epidermal growth factor receptor inhibitor-induced toxicity that can impair quality of life and treatment compliance. We sought to evaluate the efficacy of doxycycline in preventing erlotinib-induced rash (folliculitis) in patients with non-small-cell lung cancer. This open-label, randomized, prospective, phase II trial was conducted in 147 patients with locally advanced or metastatic non-small-cell lung cancer progressing after first-line chemotherapy, randomized for 4 months with erlotinib alone 150 mg/d per os (control arm) or combined with doxycycline 100 mg/d (doxycycline arm). Incidence and severity of rash, compliance, survival, and safety were assessed. Baseline characteristics of the 147 patients were well balanced in the intent-to-treat population. Folliculitis occurred in 71% of patients in the doxycycline arm and 81% in the control arm (P = .175). The severity of folliculitis and other skin lesions was lower in the doxycycline arm compared with the control arm. Other adverse events were reported at a similar frequency across arms. There was no significant difference in survival between treatment arms. The open-label design of the study and the duration of the treatment with doxycycline are limitations. Doxycycline did not reduce the incidence of erlotinib-induced folliculitis, but significantly reduced its severity. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    Full Text Available linical trials have shown that the status of the women achieving complete pathomorphological repression (CPR of a tumor is characterized by significantly improved survival as compared to that of those who have not to an equal degree. The achievement of CPR as an intermediate marker for improved survival is chiefly observed in women with aggressive subtypes of breast cancer (BC: triple-negative and HER-2-positive. In patients with the latter subtype, addition of trastuzumab to neoadjuvant chemotherapy doubles the rate of CPR and correlates with higher survival rates. The performed clinical trials have established that neoadjuvant endocrine therapy is the most suitable treatment for patients with steroid hormone receptor overexpression. Whether it may be used in combination with targeted (anti-HER-2 therapy for estrogen and HER-2 coexpression is being investigated. Neoadjuvant therapy for suitable BC stages can accelerate the assessment of novel medications through identification of predictive biological markers for response (CPR in particular. Although standard neoadjuvant therapy gives an obvious benefit to patients with CPR, other patients with the so-called residual disease are at high recurrence risk.

    Full Text Available Lung cancer is the most common cancer worldwide, accounting for 1.8 million new cases and 1.6 million deaths in 2012. Non-small cell lung cancer (NSCLC, which is one of two types of lung cancer, accounts for 85–90% of all lung cancers. Despite advances in therapy, lung cancer still remains a leading cause of death. Cancer relapse and dissemination after treatment indicates the existence of a niche of cancer cells that are not fully eradicated by current therapies. These chemoresistant populations of cancer cells are called cancer stem cells (CSCs because they possess the self-renewal and differentiation capabilities similar to those of normal stem cells. Targeting the niche of CSCs in combination with chemotherapy might provide a promising strategy to eradicate these cells. Thus, understanding the characteristics of CSCs has become a focus of studies of NSCLC therapies.

    2011-04-01

    Prostate cancer is a frequently diagnosed male cancer. In men presenting locally advanced or metastatic disease, the mainstay of treatment is hormonal suppression. Despite the castrate levels of testosterone, with time, prostate cancer gradually evolves into a castration-refractory state. Chemotherapeutic agents are able to influence the natural history of metastatic castration-resistant prostate cancer. Docetaxel is a clinically relevant, FDA-approved taxane. Today, it is the first-line chemotherapeutic agent in castration-refractory prostate cancer (CRPC). There is no standard second-line chemotherapeutic regimen. This review provides information on the efficacy of cabazitaxel as a second-line treatment for CRPC. The medline database was searched for clinical trials on chemotherapeutical treatment options of castration-resistant prostate cancer. All available data on the efficacy of cabazitaxel are summarized. New treatment strategies for castration-resistant prostate cancer should primarily focus on quality of life. In this view, vaccination therapy seems promising because of the acceptable level of toxicity. However, more research is needed to prove their efficacy in the treatment of castration-resistant prostate cancer. Cabazitaxel seems to be a promising second-line therapy in CRPC.

    Almost all breast cancer patients receive one or more adjuvant treatments consisting of tamoxifen, aromatase inhibitors, LHRH-antogonists, chemotherapy, trastuzumab, and radiotherapy. These treatments have been shown to considerably improve overall survival. As a result, long term survival for 15 and more years is achieved in more than two thirds of newly diagnosed breast cancer patients. Therefore, more interest in short and long term risks of adjuvant treatments has been arisen. The focus of this article is the long term cardiac risks of adjuvant radiotherapy in breast cancer patients and possible interactions with chemotherapy and trastuzumab. (orig.)

  4. Strategies of dose escalation in the treatment of locally advanced non-small cell lung cancer: image guidance and beyond

    2014-06-01

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

    Fatigue is a distressing symptom occurring in more than 60% of patients with cancer. The CNS stimulants modafinil and methylphenidate are recommended for the treatment of cancer-related fatigue, despite a limited evidence base. We aimed to evaluate the efficacy and tolerability of modafinil in the management of fatigue in patients with non-small-cell lung cancer (NSCLC). Adults with advanced NSCLC and performance status of 0 to 2, who were not treated with chemotherapy or radiotherapy within the last 4 weeks, were randomly assigned to daily modafinil (100 mg on days 1 to 14; 200 mg on days 15 to 28) or matched placebo. The primary outcome was change in Functional Assessment of Chronic Illness Therapy (FACIT) -Fatigue score from baseline to 28 days, adjusted for baseline fatigue and performance status. Secondary outcomes included safety and patient-reported measures of depression, daytime sleepiness, and quality of life. A total of 208 patients were randomly assigned, and 160 patients (modafinil, n = 75; placebo, n = 85) completed questionnaires at both baseline and day 28 and were included in the modified intention-to-treat analysis. FACIT-Fatigue scores improved from baseline to day 28 (mean score change: modafinil, 5.29; 95% CI, 2.57 to 8.02; placebo, 5.09; 95% CI, 2.54 to 7.65), but there was no difference between treatments (0.20; 95% CI, -3.56 to 3.97). There was also no difference between treatments for the secondary outcomes; 47% of the modafinil group and 23% of the placebo group stated that the intervention was not helpful. Modafinil had no effect on cancer-related fatigue and should not be prescribed outside a clinical trial setting. Its use was associated with a clinically significant placebo effect. © 2014 by American Society of Clinical Oncology.

    Breast cancer is the most common female cancer and globally remains a major public health concern. The diagnosis and treatment of breast cancer continues to develop. Diagnosis is now more precise, surgery is less mutilating and women now have the option of breast conserving therapy with better cosmesis, and without sacrificing survival. Radiotherapy is more targeted and the selection of patients for adjuvant chemotherapy is based not only on prognostic and predictive factors, but also on newer molecular profiling that will ensure that chemotherapy is given to the patients who need and respond to it. These developments all provide a more tailored approach to the treatment of breast cancer. Management now involves a multidisciplinary team approach in order to provide the highest standard of care for patients throughout their cancer journey from diagnosis through treatment and into follow-up care.

    2010-11-01

    Lung cancer is the most common cancer worldwide with non-small cell lung cancer (NSCLC), including squamous carcinoma, adenocarcinoma and large cell carcinoma, accounting for about 85% of all lung cancer types with most of the patients presenting with advanced disease at the time of diagnosis. In this setting first-line platinum-based chemotherapy for no more than 4-6 cycles are recommended. After these cycles of treatment, non-progressing patients enter in the so called "watch and wait" period in which no further therapy is administered until there is disease progression. In order to improve the advanced NSCLC outcomes, the efficacy of further treatment in the "watch and wait" period was investigated. This is the "maintenance therapy". Recently, the results coming from randomized phase III trials investigating two new agents, pemetrexed and erlotinib, in this setting led to their registration for maintenance therapy. Here, we report and discuss these results. Copyright © 2010 Elsevier Ltd. All rights reserved.

    The importance of evaluating physical cues in cancer research is gradually being realized. Assessment of cancer cell physical appearance, or phenotype, may provide information on changes in cellular behavior, including migratory or communicative changes. These characteristics are intrinsically different between malignant and non-malignant cells and change in response to therapy or in the progression of the disease. Here, we report that pancreatic cancer cell phenotype was altered in response to a physical method for cancer therapy, a non-invasive radiofrequency (RF) treatment, which is currently being developed for human trials. We provide a battery of tests to explore these phenotype characteristics. Our data show that cell topography, morphology, motility, adhesion and division change as a result of the treatment. These may have consequences for tissue architecture, for diffusion of anti-cancer therapeutics and cancer cell susceptibility within the tumor. Clear phenotypical differences were observed between cancerous and normal cells in both their untreated states and in their response to RF therapy. We also report, for the first time, a transfer of microsized particles through tunneling nanotubes, which were produced by cancer cells in response to RF therapy. Additionally, we provide evidence that various sub-populations of cancer cells heterogeneously respond to RF treatment.

    To evaluate the effectiveness of nivolumab as second-line treatment compared to standard therapy with docetaxel in adult patients with non-small cell lung cancer (NSCLC) in clinical practice. This is an observational, retrospective cohort study of adult patients diagnosed with NSCLC, stage III-IV, treated with docetaxel or nivolumab as second-line treatment. The end points evaluated were overall survival (OS) and progression-free survival (PFS). PFS and OS were described using the Kaplan-Meier method. The Cox proportional hazards model was applied to identify independent prognostic and predictive factors related to disease progression or death. Thirty-three patients were included in this study (i.e., 14 in the nivolumab group and 19 in the docetaxel group). Nonsquamous NSCLC was the most frequent histological subtype. Cohorts were homogeneous. The follow-up time was 116 ± 87.3 days. The median PFS was 84 days (95% CI 39-300) for patients treated with nivolumab and 61 days (95% CI 48-76) for patients treated with docetaxel. The risk of progression was 60% lower for patients treated with nivolumab (HR 0.40; 95% CI 0.16-0.97; p = 0.043) compared to patients receiving docetaxel. Among the patients treated with docetaxel, the median OS was 129 days (95% CI 106-300). More than 50% of the patients treated with nivolumab were alive at the end of the follow-up period; nevertheless, the risk difference was not statistically significant (HR 0.55; 95% CI 0.20-1.51; p = 0.244). NSCLC patients treated with nivolumab as second-line therapy had a longer PFS compared to patients treated with docetaxel in a health care environment. © 2017 S. Karger AG, Basel.

    Maintenance treatment (MTx) in responders following first-line treatment has been investigated and practiced for many cancers. Modeling and simulation may support interpretation of interim data and development decisions. We aimed to develop a modeling framework to simulate overall survival (OS) for MTx in NSCLC using tumor growth inhibition (TGI) data. TGI metrics were estimated using longitudinal tumor size data from two Phase III first-line NSCLC studies evaluating bevacizumab and erlotinib as MTx in 1632 patients. Baseline prognostic factors and TGI metric estimates were assessed in multivariate parametric models to predict OS. The OS model was externally validated by simulating a third independent NSCLC study (n = 253) based on interim TGI data (up to progression-free survival database lock). The third study evaluated pemetrexed + bevacizumab vs. bevacizumab alone as MTx. Time-to-tumor-growth (TTG) was the best TGI metric to predict OS. TTG, baseline tumor size, ECOG score, Asian ethnicity, age, and gender were significant covariates in the final OS model. The OS model was qualified by simulating OS distributions and hazard ratios (HR) in the two studies used for model-building. Simulations of the third independent study based on interim TGI data showed that pemetrexed + bevacizumab MTx was unlikely to significantly prolong OS vs. bevacizumab alone given the current sample size (predicted HR: 0.81; 95 % prediction interval: 0.59-1.09). Predicted median OS was 17.3 months and 14.7 months in both arms, respectively. These simulations are consistent with the results of the final OS analysis published 2 years later (observed HR: 0.87; 95 % confidence interval: 0.63-1.21). Final observed median OS was 17.1 months and 13.2 months in both arms, respectively, consistent with our predictions. A robust TGI-OS model was developed for MTx in NSCLC. TTG captures treatment effect. The model successfully predicted the OS outcomes of an independent study

    Full Text Available Background and objective Lung cancer is the leading form of cancer in terms of both incidence and cancer-related deaths. For patients with resectable IIIa/N2 non-small cell lung cancer (NSCLC, guidelines in and abroad recommend multidisciplinary team treatment, including surgery and chemotherapy, radiotherapy or other comprehensive treatment. Newly published evidences prove that neoadjuvant therapy can improve outcomes of NSCLC patients significantly, with advangtages in tolerability and compliance medication. Neoadjuvant therapy has been adopted mainly in locally advanced NSCLC, especially in stages IIIa/N2 patients, and chemotherapy of 2-4 cycles has become the basic pattern. Neoadjuvant therapy does not increase the concomitant complications of chemotherapy and surgery. However, challenges still exist in determining subsequent surgical timing, approach and extent of resection.

Although surgery and chemoradiotherapy can cure 80%–95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.Keywords: Cervical cancer, clinical trials, gene therapy, HPV E6 and E7 oncogenes, siRNAs

    Patients with diabetes mellitus are at increased risk of cancer development. Metformin is a well-established, effective agent for the management of type 2 diabetes mellitus. Epidemiological studies have identified an association between metformin use and a beneficial effect on cancer prevention and treatment, which has led to increasing interest in the potential use of metformin as an anticancer agent. Basic science has provided a better understanding of the mechanism of action of metformin and the potential for metformin to modulate molecular pathways involved in cancer cell signaling and metabolism. This article outlines the link between metformin and cancer, the potential for metformin in oncology, and limitations of currently available evidence.

The purpose of this study was to identify compounds that directly or indirectly modulate Src to suppress lung cancer cell growth and motility and to investigate the molecular mechanisms underlying the effects of these compounds. Methods Human non-small cell lung cancer (NSCLC cell lines (PC9, PC9/gef, A549, and H1975 with different EGFR statuses were tested by cytotoxicity and proliferation assays after AC-93253 iodide treatment. Src and Src-related protein expression in AC-93253 iodide-treated PC9, PC9/gef, and A549 cells were assessed by western blotting. The effects of AC-93253 iodide on cancer cell colony formation, invasion, and migration were assessed in PC9 and PC9/gef cells. The synergistic effects of gefitinib and AC-93253 iodide were evaluated by combination index (CI-isobologram analysis in gefitinib-resistant cell lines. The efficacy of AC-93253 iodide in vivo was determined using nude mice treated with either the compound or the vehicle. Results Among the compounds, AC-93253 iodide exhibited the most potent dose-independent inhibitory effects on the activity of Src as well as on that of the Src-related proteins EGFR, STAT3, and FAK. Furthermore, AC-93253 iodide significantly suppressed cancer cell proliferation, colony formation, invasion, and migration in vitro and tumor growth in vivo. AC-93253 iodide sensitized tumor cells to gefitinib treatment regardless of whether the cells were gefitinib-sensitive (PC9 or resistant (H1975 and PC9/gef, indicating that it may exert synergistic effects when used in combination with established therapeutic agents. Our findings also suggested that the inhibitory effects of AC-93253 iodide on lung cancer progression may be attributable to

    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

    Cervical cancer is a major gynecological cancer which involves uncontrolled cell division and tissue invasiveness of the female uterine cervix. With the availability of new technologies researchers have increased their efforts to develop novel biomarkers for early diagnosis, and evaluation and monitoring of therapeutic treatments. This approach will help in the development of early diagnosis and in increasing treatment efficacy with decreased recurrence. The present review explains the currently available biomarkers for cervical cancer diagnosis and prognosis. Apart from the currently available biomarkers the review also explains strategies for the development of biomarkers based on cellular and molecular approaches such as DNA, protein and other metabolic markers with suitable clinical examples. The investigations of specific proteins, enzymes and metabolites will establish more useful biomarkers for accurate detection and management of gynecological cancers especially cervical cancer.

    Full Text Available Christina M Dieli-Conwright, Breanna Z Orozco Division of Biokinesiology and Physical Therapy, Women's Health and Exercise Laboratory, University of Southern California, Los Angeles, CA, USA Abstract: Over the past 2 decades, great strides have been made in the field of exercise-oncology research, particularly with breast cancer. This area of research is particularly important since there are >2.8 million breast cancer survivors who are in need of an intervention that can offset treatment-related side effects. Noticeable reductions in physical fitness (ie, cardiopulmonary fitness and muscular strength, negative changes in body composition (ie, increase in body mass, decrease in lean body mass, and increase in fat mass, increased fatigue, depression, or anxiety are some of the common side effects of cancer treatments that negatively impact overall quality of life and increase the risk for the development of comorbidities. Exercise plays a vital role in improving cardiopulmonary function, psychological events, muscular strength, and endurance in breast cancer survivors, and thus should be considered as a key factor of lifestyle intervention to reverse negative treatment-related side effects. The purpose of this review is to address current perspectives on the benefits of aerobic and resistance exercise after breast cancer treatments. This review is focused on the well-established benefits of exercise on physical and emotional well-being, bone health, lymphedema management, and the postulated benefits of exercise on risk reduction for recurrence of breast cancer.

The threat to fertility that cancer treatments pose to young patients cannot be prevented in many cases, and thus research into methods for fertility preservation is developing, aiming at offering cancer patients the ability to have biologically related children in the future. This paper discusses the current status of fertility preservation methods when infertility risks are related to surgical oncologic treatments, radiation therapy, or chemotherapy. Several scientific groups and societies have developed consensus documents and guidelines for fertility preservation. Decisions about fertility and imminent potentially gonadotoxic therapies must be made rapidly. Timely and complete information on the impact of cancer treatment on fertility and fertility preservation options should be presented to all patients when a cancer treatment is planned.

    Full Text Available Resistance to progestin treatment is a major hurdle in the treatment of advanced and reoccurring endometrial cancer. Fenretinide is a synthetic retinoid that has been evaluated in clinical trials as a cancer therapeutic and chemo-preventive agent. Fenretinide has been established to be cytotoxic to many kinds of cancer cells. In the present study, we demonstrate that fenretinide decreased cell viability and induced apoptosis in Ishikawa cells, which are an endometrial cancer cell line, in dose dependent manner in-vitro. This effect was found to be independent of retinoic acid nuclear receptor signaling pathway. Further, we have shown that this induction of apoptosis by fenretinide may be caused by increased retinol uptake via STRA6. Silencing of STRA6 was shown to decrease apoptosis which was inhibited by knockdown of STRA6 expression in Ishikawa cells. Results of an in-vivo study demonstrated that intraperitoneal injections of fenretinide in endometrial cancer tumors (created using Ishikawa cells in mice inhibited tumor growth effectively. Immunohistochemistry of mice tumors showed a decrease in Ki67 expression and an increase in cleaved caspase-3 staining after fenretinide treatment when compared to vehicle treated mice. Collectively, our results are the first to establish the efficacy of fenretinide as an antitumor agent for endometrial cancer both in-vitro and in-vivo, providing a valuable rationale for initiating more preclinical studies and clinical trials using fenretinide for the treatment of endometrial cancer.

    Lung cancer is the second most frequent cancer diagnosis in Denmark. Although improved during the last decade, the prognosis of lung cancer is still poor with an overall 5-year survival rate of approximately 12%. Delay in diagnosis and treatment of lung cancer has been suggested as a potential cause of the poor prognosis and as consequence, fast track cancer care pathways were implemented describing maximum acceptable time thresholds from referral to treatment. In Denmark, patients with lung cancer are often transferred between hospitals with diagnostic facilities to hospitals with treatment facilities during the care pathway. We wanted to investigate whether this organizational set-up influenced the time that patients wait for the diagnosis and treatment. Therefore, the objective of this study was to uncover the impact of transfer between hospitals on the delay in the diagnosis and treatment of Non-Small Cell Lung Cancer (NSCLC). We performed a historical prospective cohort study using data from the Danish Lung Cancer Registry (DLCR). All patients diagnosed with primary NSCLC from January 1st 2008 to December 31st 2012 were included. Patients with unresolved pathology and incomplete data on the dates of referral, diagnosis and treatment were excluded. A total of 11 273 patients were included for further analyses. Transfer patients waited longer for treatment after the diagnosis, (Hazard ratio (HR) 0.81 (0.68-0.96)) and in total time from referral to treatment (HR 0.84 (0.77-0.92)), than no-transfer patients. Transfer patients had lower odds of being diagnosed (Odds Ratio (OR) 0.82 (0.74-0.94) and treated (OR 0.66 (0.61-0.72) within the acceptable time thresholds described in the care pathway. Fast track cancer care pathways were implemented to unify and accelerate the diagnosis and treatment of cancer. We found that the transfer between hospitals during the care pathway might cause delay from diagnosis to treatment as well as in the total time from referral to

    The development of novel antitumor drugs for the treatment of non-small cell lung carcinoma NSCLC is imperative in order to improve the efficacy of lung cancer therapy and prognosis. In the current study, we demonstrated the antitumor activity of isorhamnetin and its combinations with cisplatin and carboplatin against A-549 lung cancer cells. In order to assess the anticancer enhancing effect of isorhamnetin on cisplatin and carboplatin, A-549 cells were treated with isorhamnetin, cisplatin, carboplatin and their combinations and cell viability, cell apoptosis, cell cycle arrest as well as loss of mitochondrial membrane potential were evaluated by MTT assay, flow cytometry, confocal microscopy and fluorescence microscopy. The effect of the drugs on cancer cell migration, microtubule depolymerization as well activation of caspases was also studied. The results revealed that, as compared to single drug treatment, the combination of isorhamnetin with cisplatin and carboplatin resulted in greater effect in inhibiting cancer cell growth and inducing apoptosis. Combination of isorhamnetin with cisplatin and carboplatin resulted in more potent apoptosis induction as revealed by fluorescence microscopy using AO/PI double staining. Isorhamnetin and its combinations also triggered microtubule distortion and depolymerization. The combination of isorhamnetin with cisplatin and carboplatin increased the number of cells in G2/M phase dramatically as compared to single drug treatment. Moreover, isorhamnetin and its combinations with known anticancer drugs induced disruption of the mitochondrial membrane potential as well as activation of caspases 3, 9 and poly-(ADP-ribose) polymerase in A-549 cells. Isorhamnetin as well as its combinations with cisplatin and carboplatin resulted in inhibition of cancer cell migration significantly. Results of the current study suggest that isorhamnetin combinations with cisplatin and carboplatin might be a potential clinical chemotherapeutic

    Functional health issues and the ability to autonomously participate in social life play a more pronounced role for geriatric patients than the mere prolongation of life. Quality-adjusted life years reflect the relation of health and life span. Comorbidities and functional or cognitive impairment represent independent predictors for the overall survival of geriatric patients. This must be kept in mind when planning systemic cancer treatment. All forms of cancer-specific therapy should evaluate whether the patient can truly benefit taking into consideration geriatric aspects. This particularly demands a great deal of palliative chemotherapy. When curation is no longer possible, a cancer-specific treatment must not lead to therapy-related symptoms. Clear communication of the aims of therapy is indispensable. In addition to routine urooncologic data, other relevant information must be inquired in advance of cancer-specific treatment in order to identify those functionally or cognitively impaired patients who may not benefit from systemic cancer treatment. A precise indication with respect of age-dependent physiological changes and a clear prioritization of symptoms outline the approach for systemic cancer-specific treatment.

    Purpose: The purpose of this study was to refine the heterogeneous clinical stage IIIA non-small cell lung cancer (NSCLC) with N2 nodes status (cIIIA-N2) by clinicopathological characteristics before treatment. Methods and Materials: We analyzed data of consecutive patients with cIIIA-N2 NSCLC diagnosed between 1997 and 2010 and treated by chemoradiation therapy (CRT). The appearance of the mediastinal lymph nodes (MLNs) was classified into discrete or infiltrative according to the criteria proposed by the American College of Chest Physicians. In addition, the extent of MLN involvement (MLNI) was classified as limited (close to the primary tumor) or extensive (including upper MLNI in the case of tumors in the lower lobes and vice versa). Results: A total of 148 patients with cIIIA-N2 NSCLC was treated by CRT. The patient characteristics were as follows: males: 118; females: 30; median age: 62 years; appearance of the involved MLNs: 85 discrete, 63 infiltrative; extent of MLNI: 82 limited, 66 extensive; histology: 36 squamous, 112 nonsquamous. The median progression-free survival (PFS) and median overall survival (OS) in the entire subject population were 9.9 and 34.7 months, respectively. A discrete appearance of the involved MLNs and a limited extent of MLNI contributed significantly to a better PFS and OS. The percentages of cases with relapses within the irradiated field classified according to the characteristics of the MLNs were as follows; appearance of the MLNs (24.6% discrete, 18.9% infiltrative); extent of MLNI (25.9 limited, 17.9% extensive). Conclusions: Those with a discrete appearance of the involved MLNs and a limited extent of MLNI at diagnosis could show relatively more favorable outcomes and could be candidates for multimodality therapy.

    Purpose: To study breathing related tumor motion amplitudes by lung lobe location under controlled breathing conditions used in Stereotactic Body Radiation Therapy (SBRT) for NSCLC. Methods: Sixty-five NSCLC SBRT patients since 2009 were investigated. Patients were categorized based on tumor anatomic location (RUL-17, RML-7, RLL-18, LUL-14, LLL-9). A 16-slice CT scanner [GE RT16 Pro] along with Varian Realtime Position Management (RPM) software was used to acquire the 4DCT data set using 1.25 mm slice width. Images were binned in 10 phases, T00 being at maximum inspiration ' T50 at maximum expiration phase. Tumor volume was segmented in T50 using the CT-lung window and its displacement were measured from phase to phase in all three axes; superiorinferior, anterior-posterior ' medial-lateral at the centroid level of the tumor. Results: The median tumor movement in each lobe was as follows: RUL= 3.8±2.0 mm (mean ITV: 9.5 cm{sup 3}), RML= 4.7±2.8 mm (mean ITV: 9.2 cm{sup 3}), RLL=6.6±2.6 mm (mean ITV: 12.3 cm{sup 3}), LUL=3.8±2.4 mm (mean ITV: 18.5 cm{sup 3}), ' LLL=4.7±2.5 mm (mean ITV: 11.9 cm{sup 3}). The median respiratory cycle for all patients was found to be 3.81 ± 1.08 seconds [minimum 2.50 seconds, maximum 7.07 seconds]. The tumor mobility incorporating breathing cycle was RUL = 0.95±0.49 mm/s, RML = 1.35±0.62 mm/s, RLL = 1.83±0.71 mm/s, LUL = 0.98 ±0.50 mm/s, and LLL = 1.15 ±0.53 mm/s. Conclusion: Our results show that tumor displacement is location dependent. The range of motion and mobility increases as the location of the tumor nears the diaphragm. Under abdominal compression, the magnitude of tumor motion is reduced by as much as a factor of 2 in comparison to reported tumor magnitudes under conventional free breathing conditions. This study demonstrates the utility of abdominal compression in reducing the tumor motion leading to reduced ITV and planning tumor volumes (PTV)

    Lung cancer is the second most common cancer and the primary cause of cancer-related death in both men and women in the United States and rest of the world. Due to diagnosis at an advanced stage, it is associated with a high mortality in a majority of patients. In recent years, enormous advances have occurred in the development and application of nanotechnology in the detection, diagnosis, and therapy of cancer. This progress has led to the development of the emerging field of "cancer nanomedicine." Nanoparticle-based therapeutic systems have gained immense popularity due to their bioavailability, in vivo stability, intestinal absorption, solubility, sustained and targeted delivery, and therapeutic effectiveness of several anticancer agents. Currently, a plethora of nanocarrier formulations are utilized including lipid-based, polymeric and branched polymeric, metal-based, magnetic, and mesoporous silica. In lung cancer, nanoparticle-based therapeutics is paving the way in the diagnosis, imaging, screening, and treatment of primary and metastatic tumors. The application and expansion of novel nanocarriers for drug delivery is an exciting and challenging research filed, in particular for the delivery of emerging cancer therapies. Some of the current progress and challenges in nanoparticle-based drug delivery systems for lung cancer treatment are discussed.

    Brain metastases are common in patients with non-small cell lung cancer (NSCLC), and due to associated poor prognosis, this field is an important area of need for the development of innovative medical therapies. Therapies including local approaches through surgical intervention and/or radiation and evolving systemic therapies have led to improvements in the treatment of brain metastases in patients with lung cancer. Strategies that consider applying advanced radiation techniques to minimize toxicity, intervening early with effective systemic therapies to spare radiation/surgery, testing radiosensitization combinations, and developing drug penetrant molecules have and will continue to define new practice patterns. We believe that in carefully considered asymptomatic patients, first-line systemic therapy may be considered before radiation therapy and small-molecule targeted therapy may provide an opportunity to defer radiation therapy for recurrence or progression of disease. The next several years in oncology drug development will see the reporting on of brain penetrant molecules in oncogene-defined non-small cell lung cancer. Ongoing studies will evaluate immunotherapies in patients with brain metastases with associated endpoints. We hope that continued drug development and carefully designed clinical trials may afford an opportunity to improve the lives of patients with brain metastases.

    Despite advances in surgery, chemotherapy, and radiotherapy over the last decades, the death rate from lung cancer has remained largely unchanged, which is mainly due to metastatic disease. Because of the overall poor prognosis, new treatment strategies for lung cancer patients are urgently needed. In this review, we summarize recent advances in non-small cell lung cancer (NSCLC) screening and diagnostic workup. We discuss current clinical management, highlighting stage-specific therapy approaches, chemotherapy options for advanced-stage patients, along with new agents such as vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) monoclonal antibodies, and the EGFR-targeting tyrosine kinase inhibitors erlotinib and gefitinib, and the anaplastic lymphoma kinase (ALK) inhibitor crizotinib. Finally, we give an outlook into NSCLC disease biology, focusing on the importance of EGFR activating mutations and the role of the tumor-microenvironment. CXCR4 chemokine receptors expressed on NSCLC cells are a central pathway of NSCLC cross talk with the tumor microenvironment, as they induce activation, migration, and tumor cell adhesion to stromal cells, which in turn provides growth- and drug resistance-signals. Because of the growing evidence that the microenvironment in NSCLC promotes disease progression, we expect that selected molecular pathways of cross talk between NSCLC cells and their microenvironment will become alternative therapeutic targets in the near future.

    2017-11-01

    To review recent studies in esophagogastric cancer. Positive emission tomography (PET) scan in follow-up after curative treatment of esophagogastric cancer did not lead to improved survival. In the preoperative treatment of esophagogastric cancer, the addition of the antivascular endothelial growth factor agent bevacizumab to perioperative chemotherapy with combination epirubicin, cisplatinum, and 5-fluorouracil (5-FU; ECF) failed to improve survival compared with chemotherapy alone. In a head-to-head comparison of preoperative chemotherapy for locally advanced gastric and esophagogastric adenocarcinoma, FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) significantly improved overall survival compared with ECF. Assessing response to induction chemotherapy prior to combined preoperative chemoradiotherapy in PET nonresponding patients allowed a change in chemotherapy during subsequent radiotherapy with improved rates of pathologic complete response. In human epidermal growth factor receptor-2-positive advanced esophagogastric adenocarcinoma, second-line treatment with the chemotherapy/trastuzumab drug conjugate emtansine/trastuzumab failed to improve response or overall survival compared with treatment using paclitaxel chemotherapy. The immune checkpoint inhibitor, nivolumab, improved survival in refractory gastric cancer. Recent studies in gastric cancer clarify the optimal preoperative chemotherapy regimen and the use of PET scan as a response measure of preoperative therapy in esophagogastric cancer, and the role of targeted agents and immune checkpoint inhibitors in metastatic disease.

    2017-01-01

    Full Text Available Cancer-related fatigue is a symptom of cancer where most patients or the general practitioners tend to misinterpret due to the insufficient understanding or knowledge of cancer-related fatigue (CRF. This paper will provide a better perspective for the patients and the health professionals on how to manage and handle CRF for both mild and severe fatigue patients. Articles were selected from the searches of PubMed database that had the terms “randomized controlled trials,” “cancer,” “fatigue,” “pharmacologic treatment,” and “nonpharmacologic treatment” using both Mesh terms and keywords. The authors have reviewed the current hypothesis and evidence of the detailed etiology of the CRF present in the literature for healthier management, directives, and strategies to improve the treatment of cancer-related fatigue. An algorithm has been blueprinted on screening, and management, of the CRF, and various kinds of effective treatments and assessment tools have been briefly studied and explained. Although many strategies seemed promising, the quality of randomized controlled trials is generally quite low in studies, making it difficult to draw conclusions about the effectiveness of each self-care strategies. Therefore, future studies require better design and reporting of methodological issues to ensure evidence-based self-care recommendations for people receiving cancer treatment.

    Erlotinib (Tarceva R ) is a selective epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor in the treatment of human non-small cell lung cancer (NSCLC). Salinomycin, a polyether antibiotic, has been promising a novel therapeutic agent for lung cancer, and down-regulated the expression of thymidylate synthase (TS) in NSCLC cell lines. Previous study showed that against EGFR and TS was strongly synergistic cytotoxicity in NSCLC cells. In this study, we showed that erlotinib (1.25-10μM) treatment down-regulating of TS expression in an AKT inactivation manner in two NSCLC cell lines, human lung squamous cell carcinoma H1703 and adenocarcinoma H1975 cells. Knockdown of TS using small interfering RNA (siRNA) or inhibiting AKT activity with PI3K inhibitor LY294002 enhanced the cytotoxicity and cell growth inhibition of erlotinib. A combination of erlotinib and salinomycin resulted in synergistic enhancement of cytotoxicity and cell growth inhibition in NSCLC cells, accompanied with reduced protein levels of phospho-AKT(Ser473), phospho-AKT(Thr308), and TS. Overexpression of a constitutive active AKT (AKT-CA) or Flag-TS expression vector reversed the salinomycin and erlotinib-induced synergistic cytotoxicity. Our findings suggested that the down-regulation of AKT-mediated TS expression by salinomycin enhanced the erlotinib-induced cytotoxicity in NSCLC cells. These results may provide a rationale to combine salinomycin with erlotinib for lung cancer treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

    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.

  12. Risk of isolated nodal failure for non-small cell lung cancer (NSCLC) treated with the elective nodal irradiation (ENI) using 3D-conformal radiotherapy (3D-CRT) techniques--a retrospective analysis.

    2008-01-01

    To estimate retrospectively the rate of isolated nodal failures (INF) in NSCLC patients treated with the elective nodal irradiation (ENI) using 3D-conformal radiotherapy (3D-CRT). One hundred and eighty-five patients with I-IIIB stage treated with 3D-CRT in consecutive clinical trials differing in an extent of the ENI were analyzed. According to the extent of the ENI, two groups were distinguished: extended (n = 124) and limited (n = 61) ENI. INF was defined as regional nodal failure occurring without local progression. Cumulative Incidence of INF (CIINF) was evaluated by univariate and multivariate analysis with regard to prognostic factors. With a median follow up of 30 months, the two-year actuarial overall survival was 35%. The two-year CIINF rate was 12%. There were 16 (9%) INF, eight (6%) for extended and eight (13%) for limited ENI. In the univariate analysis bulky mediastinal disease (BMD), left side, higher N stage, and partial response to RT had a significant negative impact on the CIINF. BMD was the only independent predictor of the risk of incidence of the INF (p = 0.001). INF is more likely to occur in case of more advanced nodal status.

  13. Impact of cancer and cancer treatment on male fertility.

    2015-01-01

    While cancer, and especially testicular cancer and Hodgkin's disease, affects male fertility in many ways, the current increase of survival of male cancer patients of reproductive age or earlier has emerged as a new challenge to their subsequent ability to father children. Cancer treatments, including surgery, radiotherapy and chemotherapy, can have a transitory as well as a permanent detrimental impact on male fertility. Gonadotoxic effects and the length of time for sperm recovery after radiotherapy depends not only on initial semen quality, but also on gonadal dosage and the delivery method after chemotherapy, on the type of regimens and dosages and on the spermatogenesis phase that each drug impacts. Combination treatment with radiotherapy and chemotherapy will induce more gonadotoxicity than either modality alone. Although efforts to prevent gonadal toxicity in cancer treatment are routinely applied, sperm cryopreservation remains the gold standard to maintain male fertility after cancer survival. Fertility preservation for prepubertal boys presents the greatest problem due to the absence of mature sperm in their gonads. In this area, research efforts are concentrated on cryopreservation of immature gametes and, in particular, techniques for their maturation and proliferation after thawing.

    Reviews of yoga research that distinguish results of trials conducted during (versus after) cancer treatment are needed to guide future research and clinical practice. We therefore conducted a review of non-randomized studies and randomized controlled trials of yoga interventions for children and adults undergoing treatment for any cancer type. Studies were identified via research databases and reference lists. Inclusion criteria were the following: (1) children or adults undergoing cancer treatment, (2) intervention stated as yoga or component of yoga, and (3) publication in English in peer-reviewed journals through October 2015. Exclusion criteria were the following: (1) samples receiving hormone therapy only, (2) interventions involving meditation only, and (3) yoga delivered within broader cancer recovery or mindfulness-based stress reduction programs. Results of non-randomized (adult n = 8, pediatric n = 4) and randomized controlled trials (adult n = 13, pediatric n = 0) conducted during cancer treatment are summarized separately by age group. Findings most consistently support improvement in psychological outcomes (e.g., depression, distress, anxiety). Several studies also found that yoga enhanced quality of life, though further investigation is needed to clarify domain-specific efficacy (e.g., physical, social, cancer-specific). Regarding physical and biomedical outcomes, evidence increasingly suggests that yoga ameliorates sleep and fatigue; additional research is needed to advance preliminary findings for other treatment sequelae and stress/immunity biomarkers. Among adults undergoing cancer treatment, evidence supports recommending yoga for improving psychological outcomes, with potential for also improving physical symptoms. Evidence is insufficient to evaluate the efficacy of yoga in pediatric oncology. We describe suggestions for strengthening yoga research methodology to inform clinical practice guidelines.

    2016-03-01

    Full Text Available Definitive radiochemotherapy is the standard treatment for many patients with locally advanced nonsmall cell lung cancer (NSCLC. Treatment outcomes have improved over the last decades. Several treatment regimens have been shown effective and safe. This review summarises the results of significant studies between 1996 and 2015 on concomitant and sequential radiochemotherapy regimens and radiation dose per fraction. Beside therapy regimens, optimised radiotherapy planning is indispensable to improve outcome and minimise radiation-induced toxicity. An insight into the rationale of radiotherapy planning for stage III NSCLC is also provided.

    Genetic polymorphisms of thymidylate synthase (TYMS) gene have been reported to be associated with development or prognosis of several cancers. However, the association between polymorphisms of TYMS gene and clinical outcomes of non-small cell lung cancer (NSCLC) patients are still unknown. In the present study, we investigated the associations between single nucleotide polymorphisms (SNPs) of TYMS gene and response to chemotherapy as well as clinical outcomes in NSCLC patients. Five SNPs in TYMS gene were genotyped using the Sequenom iPLEX genotyping system in a hospital-based cohort with 500 NSCLC patients, and their associations with NSCLC outcomes were evaluated by Cox proportional hazard regression analysis under three genetic models (additive, dominant, and recessive models). Our data showed that there was no significant association between individual SNP and overall survival of NSCLC patients. However, SNP rs2847153 was significantly associated with NSCLC recurrence under recessive model. We further identified a significant interaction between rs2847153 and chemotherapy in modifying clinical outcome of patients. Our data showed that individuals carrying GG/GA genotypes of rs2847153 had a significantly better response to chemotherapy when comparing to those carrying AA genotype. Conclusively, our data suggest that SNPs rs2847153 in TYMS gene may be a potential biomarker for predicting clinical outcome and personalized treatment in NSCLC patients.

  17. Novel Immunotherapeutic Strategies of Gastric Cancer Treatment

    2011-01-01

    Full Text Available Gastric cancer (GC is the fourth most common cancer and the second most frequent cause of cancer-related deaths, accounting for 10.4% of cancer deaths worldwide. Despite the improvements, estimated cure rates for patients with advanced stages remain poor, and in the metastatic setting, chemotherapy is the mainstay of palliative therapy and results in objective response rates (ORRs of only 20–40% and median overall survivals (OS of 8–10 months. Therefore, many investigators believe that the potential for making significant progress lies in understanding and exploiting the molecular biology of these tumors to investigate new therapeutic strategies to combat GC, such as specific immunotherapy. In this paper, we analyze the different approaches used for immune-based (especially dendritic and T cells therapies to gastric cancer treatment and discuss the results obtained in preclinical models as in clinical trials.

    The purpose of this study was to verify the kinetic response of the human marrow myeloid progenitor cells to the short term use of GM-CSF and its impact on the therapeutic activity of this three-drug cisplatinum containing regimen in non small cell lung cancer (NSCLC). Sixty patients with stage 3-B and 4 NSCLC were randomised to receive GM-CSF for 3 days, five days prior to the onset of chemotherapy. The chemotherapy regimen consisted of Mitomycin-C: 6 mg/m{sup 2} on day one, Ifosfamide: 2000 mg/m{sup 2} days 1 to 3, Mesna: 2000 mg/m{sup 2} days 1 to 3, Cisplatinum: 30 mg/m{sup 2} days 1 to 3, and was repeated every 4 weeks. All the patients received 30-50 Gy of radiotherapy to the primary and/or metastatic sites. Chemotherapy cycles and overall survival (p=0.000). Administration of GM-CSF was an independent prognostic parameter in locally advanced and metastatic disease (p=0.041). In the GM-CSF receiving arm more courses could be given (117 versus 99, p=0.0415), and less courses were postponed (6 versus 22). In this arm, the mean of granulocyte nadir was higher (p=0.033) and mean time to granulocyte recovery became shorter (p=0.001) as the number of chemotherapy cycles increased. It was concluded that, dose intensification with GM-CSF prophylaxis is benefical in increasing the treatment tolerability by decreasing the intensity of granulocytopenia as well as providing rapid recovery.

    Full Text Available Abstract Background Progress in lung cancer is hampered by the lack of clinically useful diagnostic markers. The goal of this study was to provide a detailed evaluation of lung cancer tumor markers indicative of molecular abnormalities and to assess their diagnostic utility in non-small cell lung cancer (NSCLC patients. Methods Quantitative real-time RT-PCR was used to determine LunX, CK19, CEA, VEGF-C and hnRNP A2/B1 mRNA levels in peripheral blood and pleural fluid from NSCLC patients, compared with those from patients with other epithelial cancer (esophagus cancer and breast cancer, benign lung disease (pneumonia and tuberculo pleurisy and from healthy volunteers. Results In peripheral blood LunX mRNA was detectable in 75.0% (33/44 of patients with NSCLC, but not in patients with other epithelial cancer (0/28, benign lung disease (0/10 or in healthy volunteers (0/15. In contrast, all other genetic markers were detected in patients with either NSCLC, other epithelia cancer or benign lung disease, and in healthy volunteers. The expression level and positive rate of LunX mRNA in peripheral blood correlated with the pathologic stage of NSCLC (P LunX mRNA was detected in 92.9% (13/14 of malignant pleural fluid samples and was the only marker whose expression level was significantly different between malignant and benign pleural fluid (P LunX mRNA in the peripheral blood of NSCLC patients decreased shortly after clinical treatment (P = 0.005. Conclusion Of several commonly used genetic markers, LunX mRNA is the most specific gene marker for lung cancer and has potential diagnostic utility when measured in the peripheral blood and pleural fluid of NSCLC patients.

    Full Text Available Colorectal cancer (CRC was the second most frequent cancer in Europe in 2004, responsible for 13% (376,400 of all incident cancer cases. It is also the second most frequent cause of cancer mortality in Europe, with 11.9% (203,700 annual deaths. When localized, CRC is often a curable disease, but the overall prognosis is determined by the extent of local and particularly metastatic tumour spread. The disease outlook is relatively poor, because advanced disease is a significant cause of worldwide cancer-related mortality. Thus, estimated 5-year survival rates range from nearly 90% in stage I disease (Dukes’ A to less than 10% in patients with metastatic disease (Dukes’ D. Comprehensive cancer care in the 21st century is dependent on a multidisciplinary approach to patients with malignant disease. Large bowel cancer is no exception, as there is increasing clinical trial data supporting multimodal treatment for both localized and advanced tumours. This review will focus on important aspects in CRC including the latest treatment strategies (chemotherapy, radiotherapy and the targeted therapies.

    Full Text Available Abstract Background Reporting further developments evolved since the first report about this conformal technique. Methods Technical progress focused on optimization of the quality assurance (QA program, especially regarding the required work input; and on optimization of beam arrangements. Results Besides performing the regular QA program, additional time consuming dosimetric measurements and verifications no longer have to be accomplished. 'Class solutions' of treatment plans for six patients with non-resected non-small cell lung cancer in locally advanced stages are presented. Target configurations comprise one central and five peripheral tumor sites with different topographic positions to hilus and mediastinum. The mean dose to the primary tumor is 81,9 Gy (range 79,2–90,0 Gy, to macroscopically involved nodes 61,2 Gy (range 55,8–63,0 Gy, to electively treated nodes 45,0 Gy. Treatments are performed twice daily, with fractional doses of 1,8 Gy at an interval of 11 hours. Median overall treatment time is 33 days. The set-up time at the linac does not exceed the average time for any other patient. Conclusion Target splitting is a highly conformal and nonetheless non-expensive method with regard to linac and staff time. It enables secure accelerated high-dose treatments of patients with NSCLC.

    2014-01-01

    Our aim is to report on the clinical methods and outcomes of helical intensity-modulated stereotactic body radiotherapy (SBRT) for the treatment of early-stage non-small cell lung cancer (NSCLC). Seventy-nine patients with stage I NSCLC underwent helical SBRT with 48 Gy in 4 fractions or 60 Gy in 5 fractions. All patients underwent 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) or FDG-PET/computed tomography (CT) scanning in the immobilized treatment position for planned fusion with a separate kilovoltage (KV) CT simulation prior to treatment. Megavoltage CT images were obtained on the treatment unit prior to therapy and repeated at mid-fraction with comparison and fusion to the KV CT simulation planning images to assure setup accuracy. Serial follow-up with FDG-PET or FDG-PET/CT was performed at 3-4 months and every 6 months thereafter. Median follow-up was 27 months (range, 4-82 months). Overall local control rate (LCR) was 93.6% (95% confidence interval [CI], 86.0-97.3%) and 3-year overall survival (OS) was 58.4% (95% CI, 47.2-69.5%). For patients with T1N0M0 disease (n = 59) the LCR was 94.9% (95% CI, 86.1-98.3%) and the 3-year OS was 62.8% (95% CI, 49.9-73.9%). Patients treated with 60 Gy had longer 3-year OS than patients treated with 48 Gy (65.2% vs 37.5%; P = 0.044). SBRT-related toxicity was modest, with 10 patients developing grade 1/2 chest wall toxicity based on the Common Terminology Criteria for Adverse Events (CTCAE). Image-guided SBRT with helical IMRT delivered in 4 or 5 fractions of 12 Gy with rigid immobilization, FDG-PET-assisted targeting, and repeat mid-fraction CT scan is an effective treatment for early NSCLC.

  5. [Cancer treatment for patients with dementia].

    Ogawa, Asao

    2014-09-01

    Cancer is a disease associated with aging. In Japan, the rate of aging is estimated to be over 25%. Further, the prevalence of dementia also increases with age, and cancer patients with dementia are becoming more common. Dementia is a progressive condition characterized by impairment in memory and at least one other cognitive domain(language, praxis, gnosis, or executive function), as well as a compromised ability to perform daily functions. Impairment of short-term memory and executive function in particular are associated with an increased risk for functional decline and mortality. Assessment of cognitive function is necessary to ensure that cancer patients can provide informed consent and understand the risks, benefits, and alternatives of therapeutic treatment. The health care team needs to ascertain whether patients have the mental capacity for cancer treatment, will comply with the treatment schedule, and will understand when to seek help. Elderly cancer patients undergoing treatment need to be assessed for vulnerability with the comprehensive geriatric assessment (CGA).

    2014-01-01

    Hepatitis B virus (HBV), hepatitis C virus (HCV), human papillomavirus (HPV), and Epstein-Barr virus (EBV) contribute to about 10-15 % global burden of human cancers. Conventional chemotherapy or molecular target therapies have been used to treat virus-associated cancers. However, a more proactive approach would be the use of antiviral treatment to suppress or eliminate viral infections to prevent the occurrence of cancer in the first place. Antiviral treatments against chronic HBV and HCV infections have achieved this goal, with significant reduction in the incidence of hepatocellular carcinoma in treated patients. Antiviral treatments for EBV, Kaposi's sarcoma-associated herpesvirus (KSHV), and human T-cell lymphotropic virus type 1 (HTLV-1) had limited success in treating refractory EBV-associated lymphoma and post-transplant lymphoproliferative disorder, KSHV-associated Kaposi's sarcoma in AIDS patients, and HTLV-1-associated acute, chronic, and smoldering subtypes of adult T-cell lymphoma, respectively. Therapeutic HPV vaccine and RNA-interference-based therapies for treating HPV-associated cervical cancers also showed some encouraging results. Taken together, antiviral therapies have yielded promising results in cancer prevention and treatment. More large-scale studies are necessary to confirm the efficacy of antiviral therapy. Further investigation for more effective and convenient antiviral regimens warrants more attention.

    We examined the relationship of sociodemographic factors, urban/rural residence, and county-level socioeconomic factors on accrual of Maryland patients with cancer to National Cancer Institute (NCI)-sponsored cancer treatment clinical trials. Data were analyzed for the period 1999 to 2002 for 2240 Maryland patients with cancer accrued onto NCI-sponsored treatment trials. The extent to which Maryland patients with cancer and patients residing in lower socioeconomic and/or rural areas were accrued to cancer trials and were representative of all patients with cancer in Maryland was determined. Data were obtained from several sources, including NCI's Cancer Therapy Evaluation Program for Maryland patients with cancer in Cooperative Group therapeutic trials, Maryland Cancer Registry data on cancer incidence, and United States Census and the Department of Agriculture. For Maryland patients with cancer accrued onto NCI-sponsored treatment trials between 1999 and 2002, subgroups accrued at a higher rate included pediatric and adolescent age groups, white patients, female patients (for sex-specific tumors), patients with private health insurance, and patients residing in the Maryland National Capitol region. Moreover, between 1999 and 2002, there was an estimated annual decline (8.9% per year; P Maryland patients with cancer onto NCI-sponsored treatment trials based on patient age, race/ethnicity, geography of residence, and county-level socioeconomic factors. Findings provide the basis for development of innovative tailored and targeted educational efforts to improve trial accrual, particularly for the underserved.

    To explore the potential of a novel dose-volume based metric to assist in the selection of optimal fractionation schedules for lung cancer patients. Selecting the dose per fraction that maximizes the therapeutic ratio via a linear-quadratic effect on normal tissue complication probability and tumor cell survival is an optimization problem. The mathematical solution reveals that the optimal fractionation schedule is determined by a generalized dose ratio between the normal tissue and the tumor, here termed the bifurcation number B, that can be derived from the dose-volume histogram of the normal tissue. The bifurcation number characterizes the volume effect of a normal tissue and its dependency on the fractionation schedule. The clinical relevance of the bifurcation number was evaluated in 46 patients previously treated for nonsmall cell lung cancer (NSCLC) according to various fractionation protocols. Bifurcation numbers were computed for both lung and esophagus as the normal tissues. The value of the bifurcation number determines whether the volume effect reverses the traditional radiobiological advantage of small dose per fraction for the normal tissue. If B is smaller than the ratio of alpha/beta ratios between normal tissue and tumor, then a single fraction is optimal; otherwise the optimal treatment is an infinite number of doses (hence the name "bifurcation" number). These fractionation schedules correspond clinically to hypo- and standard/hyperfractionation, respectively. Compared with traditional dose-volume metrics, the bifurcation number is a unitless ratio and independent of dose fractionation. The B-numbers derived from the clinical treatment plans are also strongly consistent with historically prescribed clinical fractionation protocols for NSCLC treatments. The B-numbers for esophagus and lung for all patients receiving a high dose per fraction protocol (>7.5 Gy/fraction) were all smaller than the B-numbers for the patients receiving standard 2 Gy

    Purpose. Non-small cell lung cancer (NSCLC) is one the types of cancer with higher prevalence and mortality. Apo2-Ligand/TRAIL is a TNF family member able to induce apoptosis in tumor cells but not in normal cells. It has been tested in clinical trials against different types of human cancer including NSCLC. However, results of clinical trials have shown a limited efficacy of TRAIL-based therapies. Recently we have demonstrated that artificial lipid nanoparticles coated with bioactive Apo2L/TRAIL (LUV-TRAIL) greatly improved TRAIL cytotoxic ability being capable of killing chemoresistant hematological cancer cells. In the present work we have extended the study to NSCLC. Methods/patients. LUV-TRAIL-induced cytotoxicity was assessed on different NSCLC cell lines with different sensitivity to soluble TRAIL and on primary human tumor cells from three patients suffering from NSCLC cancer. We also tested LUV-TRAIL-cytotoxic ability in combination with several anti-tumor agents. Results. LUV-TRAIL exhibited a greater cytotoxic effect compared to soluble TRAIL both in A549 cells and primary human NSCLC cells. LUV-TRAIL-induced cell death was dependent on caspase-8 and caspase-3 activation. Moreover, combination of LUV-TRAIL with other anti-tumor agents such as flavopiridol, and SNS-032 clearly enhanced LUV-TRAIL-induced cytotoxicity against NSCLC cancer cells. Conclusion. The novel formulation of TRAIL based on displaying it on the surface of lipid nanoparticles greatly increases its anti-tumor activity and has clinical potential in cancer treatment.

    There has been a long-standing interest in the investigation of interactions in science. The objective of the study is to evaluate interaction between Epidermal Growth Factor Receptor (EGFR) mutation and treatment from randomized, phase II study of chemotherapy versus chemotherapy plus erlotinib in patients with progressive Non-Small Cell Lung Cancer (NSCLC) following clinical benefit from erlotinib. Forty-six patients with advanced stage NSCLC and progression from erlotinib were randomized to receive chemotherapy (pemetrexed or docetaxel) or chemotherapy plus erlotinib between 2008 and 2012. Patient characteristics at baseline including age, gender, tumor stage, race, smoking history and EGFR mutation status along with the clinical outcomes, namely response, Progression- Free Survival (PFS) and Overall Survival (OS) were obtained. The effects of treatment, EGFR mutation and interaction between the two on survival outcomes were evaluated using Cox proportional hazards model with first-order interaction. For PFS, there was a significant interaction between treatment (arm B) and EGFR mutation (mutant EGFR+) (p = 0.018), although the main effects of treatment (arm B vs. arm A) and EGFR mutation (mutant vs. wild-type EGFR) were statistically significant (with p = 0.03 and p = 0.088, respectively) favoring arm B and mutant EGFR+. Thus when taking the interaction between treatment and EGFR into account, the hazard ratio comparing arm B to arm A when EGFR is positive was 1.49 (95% CI: 0.72, 3.11); and the hazard ratio comparing arm B to arm A when EGFR is negative was 0.17 (95% CI: 0.04 - 0.84). Similarly, for OS, there was a significant interaction between treatment and EGFR mutation (p = 0.02), with significant main effects of treatment and EGFR favoring arm B and mutant EFGR+. Taking together, the hazard ratio comparing arm B to arm A when EGFR is positive was 1.61 (95% CI: 0.68 - 3.82); and the hazard ratio comparing arm B to arm A when EGFR is negative was 0.16 (95

    Given the increase in the age distribution of the population, an increase in cancer incidence rates are to be expected. Oral cancer is a disfiguring disease that continues to increase in incidence, particularly in the young, and to an extent that cannot be fully explained by increased exposure to known risk factors. Despite extensive research on treatment modalities towards oral cancer, the 5-year survival rate of this disease has not been improved over the last 4-5 decades. These facts strongly favour chemoprevention-systemic medication to revert, stop, or delay the carcinogenic process-as an approach to treating oral cancer. A chemopreventive approach to oral cancer most likely should encompass a combination of drugs targeting metabolic pathways relevant to oral carcinogenesis. Candidate drugs are retinoids and selective inhibitors of cyclooxygenase-2, epidermal growth factor receptor (EGFR), and peroxisome proliferator activated receptors (PPARs). Chemopreventive trials so far have used surrogate intermediate biomarkers as measurement of treatment effect. However, the efficiency of any drug for chemopreventive use should be assessed through a prospective randomized trial and evaluated by the only definitive end point for prevention of cancer, the incidence rates of new carcinomas.

    During the past decade, improvements in treatment-planning tools, computer and imaging technologies, and new therapeutic modalities have allowed radiation to be delivered in a conformal fashion while minimizing treatment toxicity. It is important that physicians involved in breast cancer treatment recognize the numerous advances that have occurred in the delivery of radiation therapy. Changes in 3 specific areas in treatment planning and delivery have revolutionized the way we approach breast cancer treatment: the design of radiation fields using computed tomography (CT) data sets, the development of 3-dimensional dose-calculation algorithms, and the development of new methods to modulate the delivery of radiation dose. With the advent of CT simulators, individual patient anatomy and pathology can be readily visualized and reconstructed in axial, coronal, and sagittal views. With an improved anatomic delineation between the target volumes and critical organ structures, the treatment fields can be designed to be more congruous to the areas at highest risk. In the past few years, new 3-dimensional dose-calculation algorithms have been generated that more accurately calculate dose distributions throughout the treatment-planning volume. Finally, modern linear accelerators allow for modulation of the dose intensity of the radiation beam, which may lead to improved aesthetics and decreased side effects while ensuring that the volumes at high risk receive the prescribed dose. Radiation therapy can be delivered safely and effectively to patients with breast cancer.

    Interleukin-35 (IL-35) has recently been implicated in tumor immunity. The aim of this study was to explore the clinical role of plasma IL-35 in patients with non-small cell lung cancer (NSCLC). Plasma collected from 106 patients with NSCLC cases and 78 healthy controls (HC) were subjected to IL-35 enzyme-linked immunosorbent assay (ELISA) and relationships between plasma IL-35 levels and clinical characteristics were evaluated. The correlation of IL-35 and overall survival was analyzed using Kaplan-Meier method. The prognostic value of IL-35 was tested using univariate and multivariate analysis. Circulating IL-35 levels were significantly higher in the NSCLC group in comparison with the HC group (21.37 ± 11.55 pg/ml vs. 10.09 ± 5.32 pg/ml, p 35 correlated positively with tumor TNM stage (p 35 showed an inverse correlation with overall survival. Univariate and multivariate analysis indicated that plasma IL-35 was an independent prognostic factor for NSCLC patients. Circulating IL-35 in NSCLC patients significantly increased. IL-35 is a promising potential biomarker in prognostication of clinical outcome of NSCLC patients and the regulation of IL-35 expression may provide a new target for the treatment of NSCLC patients.

    Practice guidelines have been developed for early-stage and locally advanced non-small cell lung cancer (NSCLC). However, many common clinical scenarios still require individualized decision making. This is true for locoregional relapse after initial stereotactic radiotherapy (stereotactic body radiation therapy or stereotactic ablative radiotherapy; SBRT or SABR), an increasingly utilized curative treatment option for stage I NSCLC. A consortium of expert radiation oncologists was established with the aim of providing treatment recommendations. In this scenario, a case was distributed to six radiation oncologists who provided their institutions' treatment recommendations. In this case, a patient developed local and mediastinal relapse after SABR (45 Gy, 3 fractions), comparable to the tumor burden in de novo stage IIIA NSCLC. Treatment recommendations were tabulated and a consensus conclusion was developed. Three institutions recommended evaluation for surgery. If the patient was not a surgical candidate, and/or refused surgery, definitive chemoradiation was recommended, including retreating the primary to full dose. European participants were more in favor of a non-surgical approach. None of the participants were reluctant to prescribe reirradiation, but two institutions prescribed doses lower than 60 Gy. Platinum-based doublets together with intensity-modulated radiotherapy were preferred. The institutional recommendations reflect the questions and uncertainties discussed in current stage III guidelines. All institutions agreed that previous SABR is not a contraindication for salvage chemoradiation. In the absence of high-quality prospective trials for recurrent NSCLC, all treatment options recommended in current guidelines for stage III disease can be considered in clinical scenarios such as this.

    Full Text Available Recent innovations in thulium laser techniques have allowed application in the treatment of bladder cancer. Laser en bloc resection of bladder cancer is a transurethral procedure that may offer an alternative to the conventional transurethral resection procedure. We conducted a review of basic thulium laser physics and laser en bloc resection procedures and summarized the current clinical literature with a focus on complications and outcomes. Literature evidence suggests that thulium laser techniques including smooth incision, tissue vaporization, and en bloc resection represent feasible, safe, and effective procedures in the treatment of bladder cancer. Moreover, these techniques allow improved specimen orientation and accurate determination of invasion depth, facilitating correct diagnosis, restaging, and re-evaluation of the need for a second resection. Nonetheless, large-scale multicentre studies with longer follow-up are warranted for a robust assessment. The present review is meant as a quick reference for urologists.

    INTRODUCTION: The traditional first-line treatment for patients with advanced ovarian cancer with primary debulking surgery (PDS) and adjuvant chemotherapy is controversial as some authors report a potential benefit from the alternative treatment with neoadjuvant chemotherapy (NACT) and interval...... debulking surgery. The aim of this study was to investigate the use of NACT in Denmark in regard to increased use and regional differences. MATERIAL AND METHODS: Stage IIIC and IV ovarian cancer patients treated in the five Danish tertiary referral centres in the 2005-2010-period were included. The study...... is based on validated data from The Danish Gynaecological Cancer Database. RESULTS: Of the 1,367 eligible patients 1,069 were treated with PDS and 298 with NACT. In 2005-2007, 11% of patients were treated with NACT. In 2008-2010, this percentage had risen to 30% (p

    Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, with high morbidity and mortality rates. Numerous diagnosis and treatment methods have been proposed, and the prognosis of NSCLC has improved to a certain extent. However, the mechanisms of NSCLC remain largely unknown, and additional studies are required. In the present study, the RNA sequencing dataset of NSCLC was downloaded from the Gene Expression Omnibus (http://www.ncbi.nlm.nih.gov/geo/). The clean reads obtained from the raw data were mapped to the University of California Santa Cruz human genome (hg19), based on TopHat, and were assembled into transcripts via Cufflink. The differential expression (DE) and differential alternative splicing (DAS) genes were screened out through Cuffdiff and rMATS, respectively. The significantly enriched gene ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes pathways were obtained through the Database of Annotation, Visualization and Integrated Discovery (DAVID). Different numbers of DE and DAS genes were identified in different types of NSCLC samples, but a number of common functions and pathways were obtained, including biological processes associated with abnormal immune and cell activity. GO terms and pathways associated with substance metabolism, including the insulin signaling pathway and oxidative phosphorylation, were enriched in DAS genes rather than DE genes. Integrated analysis of differential expression and alternative splicing may be helpful in understanding the mechanisms of NSCLC, in addition to its early diagnosis and treatment.

    2015-07-01

    Full Text Available The purpose of this paper is to present a review of highly developed medicinal usages of plants in the treatment of cancer. In the last decades, the cancer treatment has been included in this range of plant use, due to plant active substances. Active substances or secondary metabolites are generally known for their widespread application. When it comes to the cancer treatment, these substances affect the uncontrolled cell division. Therefore, the plants which are the source of these substances are proved to be irreplaceable in this field of medicine. This paper deals with some of the most significant plants well known for their multiple aspects of beneficial medicinal influence. The group of the plants described is comprised of the following species: Taxus brevifolia (Taxaceae, Catharanthus roseus (Apocynaceae, Podophyllum peltatum (Berberidaceae, Camptotheca accuminata (Cornaceae, and Cephalotaxus harringtonia (Cephalotaxaceae. The comprehensive description of the plants in this paper includes the morphological characteristics, the features and the representation of the molecular structures of active substances, the particular influence that these active substances have and the general importance of the substances as seen from the aspect of cancer treatment mostly with reference to the impacts on cell cycle.

  9. Imaging Surveillance After Primary Breast Cancer Treatment

    OBJECTIVE Current clinical guidelines are consistent in supporting annual mammography for women after treatment of primary breast cancer. Surveillance imaging beyond standard digital mammography, including digital breast tomosynthesis (DBT), breast ultrasound, and MRI, may improve outcomes. This article reviews the evidence on the performance and effectiveness of breast imaging modalities available for surveillance after treatment of sporadic unilateral primary breast cancer and identifies additional factors to be considered when selecting an imaging surveillance regimen. CONCLUSION Evidence review supports the use of mammography for surveillance after primary breast cancer treatment. Variability exists in guideline recommendations for surveillance initiation, interval, and cessation. DBT offers the most promise as a potential modality to replace standard digital mammography as a front-line surveillance test; a single published study to date has shown a significant decrease in recall rates compared with standard digital mammography alone. Most guidelines do not support the use of whole-breast ultrasound in breast cancer surveillance, and further studies are needed to define the characteristics of women who may benefit from MRI surveillance. The emerging evidence about surveillance imaging outcomes suggests that additional factors, including patient and imaging characteristics, tumor biology and gene expression profile, and choice of treatment, warrant consideration in selecting personalized posttreatment imaging surveillance regimens.

    In outcome studies of oncology patients undergoing radiation, researchers extract valuable information from medical records generated before, during, and after radiotherapy visits, such as survival data, toxicities, and complications. Clinical studies rely heavily on these data to correlate the treatment regimen with the prognosis to develop evidence-based radiation therapy paradigms. These data are available mainly in forms of narrative texts or table formats with heterogeneous vocabularies. Manual extraction of the related information from these data can be time consuming and labor intensive, which is not ideal for large studies. The objective of this study was to adapt the interactive information extraction platform Information and Data Extraction using Adaptive Learning (IDEAL-X) to extract treatment and prognosis data for patients with locally advanced or inoperable non-small cell lung cancer (NSCLC). We transformed patient treatment and prognosis documents into normalized structured forms using the IDEAL-X system for easy data navigation. The adaptive learning and user-customized controlled toxicity vocabularies were applied to extract categorized treatment and prognosis data, so as to generate structured output. In total, we extracted data from 261 treatment and prognosis documents relating to 50 patients, with overall precision and recall more than 93% and 83%, respectively. For toxicity information extractions, which are important to study patient posttreatment side effects and quality of life, the precision and recall achieved 95.7% and 94.5% respectively. The IDEAL-X system is capable of extracting study data regarding NSCLC chemoradiation patients with significant accuracy and effectiveness, and therefore can be used in large-scale radiotherapy clinical data studies.

    To investigate the probability of death (POD) from any causes by time after diagnosis of non-small cell lung cancer (NSCLC) and the factors associated with survival for NSCLC patients. A total of 202,914 patients with NSCLC from 2004 to 2013 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. The overall survival (OS) and lung cancer-specific survival (LCSS) were calculated and POD from any causes at different time periods after diagnosis was explored. The predictive factors for OS, LCSS and survival from non-lung cancer deaths were investigated using multivariate analysis with Cox proportional hazards regression and competing risk regression analysis. The 5- and 10-year OS were 20.4% and 11.5%, accordingly that for LCSS were 25.5% and 18.4%, respectively. Lung cancer contributed 88.3% (n = 128,402) of the deaths. The POD from lung cancer decreased with time after diagnosis. In multivariate analysis, advanced age and advanced stage of NSCLC were associated with decreased OS and LCSS. Comparing to no surgery, any kind of resection conferred lower risk of death from lung cancer and higher risk of dying from non-lung cancer conditions except lobectomy or bilobectomy, which was associated with lower risk of death from both lung cancer and non-lung cancer conditions. Most of the patients with NSCLC died from lung cancer. Rational surveillance and treatment policies should be made for them. Early stage and lobectomy or bilobectomy were associated with improved OS and LCSS. It is reasonable to focus on early detection and optimal surgical treatment for NSCLC.

    Minocycline is a semisynthetic tetracycline derivative; it has anti-inflammatory and anti-cancer effects distinct from its antimicrobial function. However, the molecular mechanism of minocycline-induced cytotoxicity in non-small cell lung cancer (NSCLC) cells has not been identified. Rad51 plays a central role in homologous recombination and high levels of Rad51 expression are observed in chemo- or radioresistant carcinomas. Our previous studies have shown that the MKK1/2-ERK1/2 signal pathway maintains the expression of Rad51 in NSCLC cells. In this study, minocycline treatment inhibited cell viability and proliferation of two NSCLC cells, A549 and H1975. Treatment with minocycline decreased Rad51 mRNA and protein levels through MKK1/2-ERK1/2 inactivation. Furthermore, expression of constitutively active MKK1 (MKK1-CA) vectors significantly rescued the decreased Rad51 protein and mRNA levels in minocycline-treated NSCLC cells. However, combined treatment with MKK1/2 inhibitor U0126 and minocycline further decreased the Rad51 expression and cell viability of NSCLC cells. Knocking down Rad51 expression by transfection with small interfering RNA of Rad51 enhanced the cytotoxicity and cell growth inhibition of minocycline. Mitomycin C (MMC) is typically used as a first or second line regimen to treat NSCLC. Compared to a single agent alone, MMC combined with minocycline resulted in cytotoxicity and cell growth inhibition synergistically in NSCLC cells, accompanied with reduced activation of phospho-ERK1/2, and reduced Rad51 protein levels. Overexpression of MKK1-CA or Flag-tagged Rad51 could reverse the minocycline and MMC-induced synergistic cytotoxicity. These findings may have implications for the rational design of future drug regimens incorporating minocycline and MMC for the treatment of NSCLC. Copyright © 2015 Elsevier Inc. All rights reserved.

    2014-03-01

    Full Text Available There is a major unmet medical need for effective and well-tolerated treatment options for patients with advanced nonsmall cell lung cancer (NSCLC, in both first-line and relapsed/refractory settings. Experimental evidence has validated signalling pathways that regulate tumour angiogenesis, including the vascular endothelial growth factor (VEGF, platelet-derived growth factor (PDGF and fibroblast growth factor (FGF pathways, as valid anti-cancer drug targets. However, to date, bevacizumab (an anti-VEGF monoclonal antibody is the only antiangiogenic agent to be approved for the treatment of NSCLC. Many other agents, including antibodies, small-molecule tyrosine kinase inhibitors and vascular disrupting agents, have been assessed in phase III trials but have generally failed to demonstrate clinically meaningful benefits. This lack of success probably reflects the redundancy of proangiogenic pathways and the molecular and clinical heterogeneity of NSCLC. In this review we summarise recently completed and ongoing randomised clinical trials of emerging antiangiogenic agents in patients with NSCLC. We highlight recent promising data with agents that simultaneously inhibit multiple proangiogenic pathways, including the PDGF and FGF pathways, as well as the VEGF pathway. Finally, we discuss the outlook for antiangiogenic agents in NSCLC, emphasising the need for clinically validated prognostic and predictive biomarkers to identify patients most likely to respond to therapy.

    The Dean and Betty Gallo Prostate Cancer Center (GPCC) was established with the goal of eradicating prostate cancer and improving the lives of men at risk for the disease through research, treatment, education and prevention. GPCC was founded in the memory of Dean Gallo, a beloved New Jersey Congressman who died tragically of prostate cancer diagnosed at an advanced stage. GPCC unites a team of outstanding researchers and clinicians who are committed to high-quality basic research, translation of innovative research to the clinic, exceptional patient care, and improving public education and awareness of prostate cancer. GPCC is a center of excellence of The Cancer Institute of New Jersey, which is the only NCI-designated comprehensive cancer center in the state. GPCC efforts are now integrated well as part of our Prostate Program at CINJ, in which Dr. Robert DiPaola and Dr. Cory Abate-Shen are co-leaders. The Prostate Program unites 19 investigators from 10 academic departments who have broad and complementary expertise in prostate cancer research. The overall goal and unifying theme is to elucidate basic mechanisms of prostate growth and oncogenesis, with the ultimate goal of promoting new and effective strategies for the eradication of prostate cancer. Members' wide range of research interests collectively optimize the chances of providing new insights into normal prostate biology and unraveling the molecular pathophysiology of prostate cancer. Cell culture and powerful animal models developed by program members recapitulate the various stages of prostate cancer progression, including prostatic intraepithelial neoplasia, adenocarcinoma, androgen-independence, invasion and metastases. These models promise to further strengthen an already robust program of investigator-initiated therapeutic clinical trials, including studies adopted by national cooperative groups. Efforts to translate laboratory results into clinical studies of early detection and

    Prostate cancer treatment results in several sexually related side effects beyond the well studied erectile dysfunction. Climacturia (leakage of urine during orgasm) has been reported after prostatectomy but studies have been limited by multiple factors. In this study we examine the prevalence, causes and impact on orgasm function of climacturia after definitive treatment of prostate cancer with surgery or radiation. A total of 906 anonymous surveys were sent to patients with prostate cancer treated with surgery and/or radiation. Respondents were asked about the presence of urinary leakage, climacturia and various elements related to sexual and orgasmic function. We estimated the prevalence of climacturia, evaluated the differences between those with and without climacturia, and assessed the impact of climacturia on orgasmic function. Overall 412 surveys were returned and available for analysis, and of these respondents 75.2% were sexually active or experiencing orgasms. Climacturia was reported by 22.6% of these respondents, and by 28.3%, 5.2% and 28.6% of those treated with surgery, radiation, or both, respectively (p orgasmic function and satisfaction. Climacturia is experienced by a substantial proportion of men after undergoing definitive treatment of prostate cancer. We found a complex relationship between stress urinary incontinence and climacturia, and noted that the presence of climacturia does not necessarily negatively impact sexual satisfaction.

    Japanese women bear children at a later age. Thus, fertility-sparing treatment for gynecologic cancer is very important. Per the Japanese treatment guidelines for cervical cancer, the uterus can be preserved by performing cervical conization alone in patients with stage I A1 disease. Radical trachelectomy (RT) is not yet recommended for patients with stage I A2 or I B 1 disease in Japan. Further, RT will not be popular in Japan because cervical cancer can be prevented with HPV vaccine. The efficacy of fertility-sparing treatment with a high-dose of medroxyprogesterone acetate for grade 1 endometrial cancer was proven in a Japan clinical oncology group (JCOG) phase II study. Japanese multi-institutional retrospective investigation data confirm that fertility-sparing surgery is safe for patients with stage I A disease with non-clear cell histology grade 1 or 2. These data suggest that patients with stage I A disease with clear cell histology and those with stage I C disease with non-clear cell histology grade 1 or 2 can be candidates for fertility sparing surgery followed by adjuvant chemotherapy.

    Ultrasonic transabdominal and transrectal investigations, computed tomography, endoscopic photodynamic studies, polyfocal biopsy of the urinary bladder were used in examination of 1238 patients which were diagnosed to have urinary bladder cancer. 894 patients underwent transurethral resection of the bladder. Morphologically, cancer of the urinary bladder has an inductory effect on intact parts of the bladder mucosa. This means that even most radical resection does not eliminate grounds for a new tumor growth. Radical cystectomy was performed in diffuse papillomatosis, multiple stage T2 tumors of high-grade malignancy, tumors at stage T3, T4, Nx, MO, in rapid recurrent tumors after conservative or operative treatment.

    We recently demonstrated that brain endothelial cells and astrocytes protect cancer cells from chemotherapy through an endothelin-dependent signaling mechanism. Here, we evaluated the efficacy of macitentan, a dual endothelin receptor (ETAR and ETBR) antagonist, in the treatment of experimental breast and lung cancer brain metastases. The effect of macitentan on astrocyte- and brain endothelial cell-mediated chemoprotective properties was measured in cytotoxic assays. We compared survival of mice bearing established MDA-MB-231 breast cancer or PC-14 non-small cell lung cancer (NSCLC) brain metastases that were treated with vehicle, macitentan, paclitaxel, or macitentan plus paclitaxel. Cell division, apoptosis, tumor vasculature, and expression of survival-related proteins were assessed by immunofluorescent microscopy. Cancer cells and tumor-associated endothelial cells expressed activated forms of AKT and MAPK in vehicle- and paclitaxel-treated groups in both metastasis models, but these proteins were downregulated in metastases of mice that received macitentan. The survival-related proteins Bcl2L1, Gsta5, and Twist1 that localized to cancer cells and tumor-associated endothelial cells in vehicle- and paclitaxel-treated tumors were suppressed by macitentan. Macitentan or paclitaxel alone had no effect on survival. However, when macitentan was combined with paclitaxel, we noted a significant reduction in cancer cell division and marked apoptosis of both cancer cells and tumor-associated en
