    Full Text Available PURPOSE: To assess the cost effectiveness of adding cetuximab to platinum-based chemotherapy in first-line treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC from the perspective of the Canadian public healthcare system. METHODS: We developed a Markov state transition model to project the lifetime clinical and economic consequences of recurrent or metastatic HNSCC. Transition probabilities were derived from a phase III trial of cetuximab in patients with recurrent or metastatic HNSCC. Cost estimates were obtained from London Health Sciences Centre and the Ontario Case Costing Initiative, and expressed in 2011 CAD. A three year time horizon was used. Future costs and health benefits were discounted at 5%. RESULTS: In the base case, cetuximab plus platinum-based chemotherapy compared to platinum-based chemotherapy alone led to an increase of 0.093 QALY and an increase in cost of $36,000 per person, resulting in an incremental cost effectiveness ratio (ICER of $386,000 per QALY gained. The cost effectiveness ratio was most sensitive to the cost per mg of cetuximab and the absolute risk of progression among patients receiving cetuximab. CONCLUSION: The addition of cetuximab to standard platinum-based chemotherapy in first-line treatment of patients with recurrent or metastatic HNSCC has an ICER that exceeds $100,000 per QALY gained. Cetuximab can only be economically attractive in this patient population if the cost of cetuximab is substantially reduced or if future research can identify predictive markers to select patients most likely to benefit from the addition of cetuximab to chemotherapy.

    The First-Line Erbitux in Lung Cancer (FLEX) trial showed that the addition of cetuximab to chemotherapy followed by weekly cetuximab maintenance significantly improved survival in the first-line treatment of advanced non-small cell lung cancer (NSCLC). The phase IIIb NSCLC Erbitux Trial (NEXT) trial (NCT00820755) investigated the efficacy and safety of weekly and every 2 weeks cetuximab maintenance therapy in this setting. Patients were treated with platinum-based chemotherapy plus cetuximab, and those progression-free after four to six cycles were randomized to every 2 weeks (500 mg/m(2)) or weekly (250 mg/m(2)) cetuximab maintenance. Randomization was stratified for tumor histology and response status. The primary endpoint for a regimen would be reached if the lower boundary of the 95 % confidence interval (CI) for the 1-year survival rate exceeded 55 %. A planned 480 patients were to be randomized. However, enrollment was curtailed following a negative opinion from the European Medicines Agency with regard to the use of cetuximab in this setting. After combination therapy, 311/583 (53.3 %) patients without progression were randomized to maintenance therapy: 157 to every 2 weeks cetuximab and 154 to weekly cetuximab. Baseline characteristics were balanced between these groups and exposure to cetuximab was similar. The 1-year survival rate was 62.8 % (95 % CI, 54.7-70.0) for every 2 weeks cetuximab and 64.4 % (95 % CI, 56.2-71.4) for weekly cetuximab. Safety profiles were similar, manageable, and in line with expectations. Therefore, in patients with advanced NSCLC who were progression-free after four to six cycles of first-line chemotherapy plus cetuximab, weekly and every 2 weeks cetuximab maintenance therapy were associated with similar survival outcomes.

However, acquired resistance is inevitable, but the salvage therapies are still unclear.Patients and methods: We designed a retrospective study of the salvage therapy and enrolled patients with stage IV lung adenocarcinoma who had mutated EGFR and developed an acquired resistance to the first-line gefitinib in two university-affiliated hospitals in Taiwan during June 2011 to December 2014. Age, sex, smoking history, EGFR gene mutation, performance statuses, response rate, PFS2 (the PFS in salvage therapy, and overall survival (OS2, the OS in salvage therapy were recorded.Results: Two hundred and nine patients with mutated EGFR and who took gefitinib as first-line therapy were identified in the period, and a total of 98 patients who had been treated with salvage therapy with cytotoxic chemotherapy or erlotinib were eligible for this

    To compare the effect of first-line treatment with platinum-based chemotherapy and non-platinum-based chemotherapy in patients with lung metastases from triple negative breast cancer (TNBC). Sixty-five eligible patients were divided into platinum-treated group and non-platinum-treated group according to the first-line therapy. Factors predicting the chemotherapeutic efficacy included overall survival (OS), progression-free survival (PFS) and objective response (OR). In the platinum-treated group of 32 patients, 2 cases (6.3%) achieved CR, 16 cases (50.0%) achieved PR, 11 (34.4%) cases achieved SD, and 3 patients (9.4%) achieved PD. In the non-platinum-treated group of 33 patients, 2 cases (6.1%) achieved CR, 6 cases (18.2%) achieved PR, 16 cases (48.5%) achieved SD, and 9 cases (27.3%) achieved PD. Median PFS was significantly longer in the platinum-treated group than in the non-platinum-treated group (10 months vs. 6.0 months, P = 0.012), and OS was also improved (32 months vs. 22 months, P = 0.006). Multivariate analysis of several factors including local-regional lymph node involvement, lung metastasis-related symptoms, first-line platinum-based chemotherapy, disease-free interval, size and number of lung lesions, showed that first-line platinum-based chemotherapy was an independent prognostic factor for TNBC patients with lung metastases. Compared with non-platinum-based chemotherapy, the first-line platinum-based chemotherapy can improve PFS and OS in TNBC patients with metastases confined to the lungs.

    Adjuvant platinum-based chemotherapy has developed its stability as the first-line treatment in advanced non-small cell lung cancer (NSCLC). The objective of this study was to investigate the prognostic value of meningioma-associated protein (MAC30) on adjuvant platinum-based chemotherapeutic response and survival in patients with NSCLC. A total of 174 retrospective stage III B to IV Chinese patients with NSCLC were enrolled in the study. Among all cases, 85 patients were given platinum-based chemotherapy and another 89 patients received molecularly targeted therapy. The expression of MAC30 in tumor samples was confirmed via immunohistochemical staining to correlate with the therapeutic response and survival of patients. Patients having NSCLC with MAC30 overexpression showed a poorer response to platinum-based chemotherapy, while there was no prognostic value of MAC30 expression on molecularly targeted therapy. Further, patients receiving platinum-based chemotherapy with enhanced MAC30 expression exhibited shorter survival. A multivariate analysis exhibited that increased MAC30 expression was an independent prognostic factor for overall survival in patients having NSCLC with platinum-based chemotherapy. In conclusion, patients having NSCLC with higher MAC30 expression resisted to platinum-based chemotherapy and exhibited worse survival. © The Author(s) 2015.

    Lung cancer is one of the leading causes of cancer-related death in the world. Platinum-based chemotherapy is the first-line treatment for non-small-cell lung cancer (NSCLC), however, the therapeutic efficiency varies remarkably among individuals. A large number of pharmacogenomics studies aimed to identify genetic variations which can be used to predict platinum response. Those studies are leading NSCLC treatment to the new era of precision medicine. In the current review, we provided a comprehensive update on the main recent findings of genetic variations which can be used to predict platinum sensitivity in the NSCLC patients.

    In the phase III LUX-Lung 8 trial, afatinib significantly improved progression-free survival (PFS) and overall survival (OS) versus erlotinib in patients with squamous cell carcinoma (SCC) of the lung progressing during or after platinum-based chemotherapy. Patient-reported outcomes (PROs) and health-related quality of life (QoL) in these patients are presented. Patients (n = 795) were randomized 1:1 to oral afatinib (40 mg/d) or erlotinib (150 mg/d). PROs were collected (baseline, every 28 days until progression, 28 days after discontinuation) using the European Organization for Research and Treatment of Cancer QoL questionnaire and lung cancer-specific module. The percentage of patients improved during therapy, time to deterioration (TTD), and changes over time were analyzed for prespecified lung cancer-related symptoms and global health status (GHS)/QoL. Questionnaire compliance was 77.3% to 99.0% and 68.7% to 99.0% with afatinib and erlotinib, respectively. Significantly more patients who received afatinib versus erlotinib experienced improved scores for GHS/QoL (36% vs. 28%; P = .041) and cough (43% vs. 35%; P = .029). Afatinib significantly delayed TTD in dyspnea (P = .008) versus erlotinib, but not cough (P = .256) or pain (P = .869). Changes in mean scores favored afatinib for cough (P = .0022), dyspnea (P = .0007), pain (P = .0224), GHS/QoL (P = .0320), and all functional scales. Differences in adverse events between afatinib and erlotinib, specifically diarrhea, did not affect GHS/QoL. In patients with SCC of the lung, second-line afatinib was associated with improved prespecified disease-related symptoms and GHS/QoL versus erlotinib, complementing PFS and OS benefits with afatinib.

    Background To investigate the value of the metabolic tumor response assessed with 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), compared with clinicobiological markers, to predict the response disease to first line platinum based chemotherapy in advanced thymic epithelial tumors (TETs). Methods Twenty patients with diagnosis of TET and stage of disease III and IV sec, Masaoka-Koga, were retrospectively included in this monocentric study. Different pre-treatment clinical, biological and pathological parameters, including histotype sec, WHO 2004 and stage of disease sec, Masaoka-Koga were assessed. Tumor glucose metabolism at baseline and its change after the first line platinum based chemotherapy (from 4 to 6 cycles) were assessed using FDG-PET, moreover the response disease was assessed using total body CT scan for the evaluation of RECIST criteria 1.1. Results Twelve patients had an objective response to the first line platinum based chemotherapy according RECIST criteria 1.1 and all of them started with a SUVmax at baseline major than 5, indeed the other eight patients, non-responders to chemotherapy, had a SUVmax at baseline minor than 5. Conclusions It is important to define the chemosensitivity of advanced TETs early. Combining bio-pathological parameters with the metabolism at baseline assessed with FDG-PET can help the physician to early predict the probability of obtaining a disease response to first line platinum based chemotherapy. The SUVmax cut off of 5 at 18FDG-PET/CT performed at baseline treatment might be a new parameter for choosing the most powerful first line of chemotherapy. Given these results, further prospective studies are needed to establish a new first line therapy in advanced TETs with a low SUVmax at baseline, non-responders to conventional chemotherapy.

    Objective:To explore the expression of breast cancer susceptibility gene 1 (BRCA1) in human colorectal cancer and its correlation with efifcacy of platinum-based chemotherapy. Methods:A total of 78 samples from patients with colorectal cancer and receiving platinum-based chemotherapy were selected, and meanwhile 14 cases of normal colonic mucosa samples were selected as a normal control, 12 cases of non-cancerous tissue in colorectal cancer samples were selected as a pericarcinorma control. The expression of BRCA1 in these tissues was detected using immunohistochemical S-P method, and all patients treated with drugs were followed-up for survival time. Results: The positive rate of BRCA1 expression in colorectal cancer tissue was 52.6%, signiifcantly lower than that in the control groups. BRCA1 expression was closely associated with histological differentiation degrees (χ2=14.16,P=0.001), but not with the age, gender, local inifltration, lymph node metastasis and TNM staging. Comparing with those with positive BRCA1 expression, the patients with negative BRCA1 expression after oxaliplatin-based chemotherapy had signiifcantly longer disease-free survival (DFS) (P=0.032). Conclusion:Application of oxaliplatin-based chemotherapy in the patients with negative BRCA1 expression can obtain the survival beneift, and the level of BRCA1 expression can be useful in the selection of chemotherapy regimens and evaluation of prognosis for patients with colorectal cancer after surgery.

    Background: Possible targeted therapies for metastatic triple negative breast cancer (TNBC) include cytotoxic chemotherapy that causes interstrand breaks (platinum-based drugs). The excision repair cross-complementation 1 (ERCC1) enzyme plays an essential role in the nucleotide excision repair pathway, removing platinum-induced DNA adducts and contributing to cisplatin resistance. Detecting ERCC1 overexpression is important in considering treatment options for metastatic TNBC, including individualized approaches to therapy, and may facilitate improved responses or reduction of unnecessary toxicity. We hypothesized that assigning cisplatin based on pretreatment ERCC1 expression would improve response and survival. This study was conducted to assess the impact of ERCC1 expression on PFS, OS and response rates in metastatic triple negative breast cancer patients treated with platinum-based chemotherapy. Methods: From June 2012 to November 2013, 52 metastatic triple negative breast cancer patients were enrolled. ERCC1 protein expression was detected from pretreatment biopsies by Immunohistochemistry. All patients received cisplatin plus paclitaxel. The primary end point was the impact of ERCC1 expression on PFS and OS. Results: 34 patients (65.4%) showed positive ERCC1 expression while 18 (34.6%) proved negative. Positive ERCC1 expression was associated with short PFS (median, 5 months vs. 7 months; P = 0.043), short OS (median, 9 months vs. 11 months; P = 0.033) and poor response to cisplatin based chemotherapy (P = 0.046). Conclusions: This prospective study further validated ERCC1 as a reliable biomarker for customized chemotherapy in metastatic triple negative breast cancer patients. High expression of ERCC1 was thereby fond to be significantly associated with poor outcome in patients treated with platinum based chemotherapy.

    Full Text Available BACKGROUND: Palonosetron is a potent second generation 5- hydroxytryptamine-3 selective antagonist which can be administered by either intravenous (IV or oral routes, but subcutaneous (SC administration of palonosetron has never been studied, even though it could have useful clinical applications. In this study, we evaluate the bioavailability of SC palonosetron. PATIENTS AND METHODS: Patients treated with platinum-based chemotherapy were randomized to receive SC or IV palonosetron, followed by the alternative route in a crossover manner, during the first two cycles of chemotherapy. Blood samples were collected at baseline and 10, 15, 30, 45, 60, 90 minutes and 2, 3, 4, 6, 8, 12 and 24 h after palonosetron administration. Urine was collected during 12 hours following palonosetron. We compared pharmacokinetic parameters including AUC0-24h, t1/2, and Cmax observed with each route of administration by analysis of variance (ANOVA. RESULTS: From October 2009 to July 2010, 25 evaluable patients were included. AUC0-24h for IV and SC palonosetron were respectively 14.1 and 12.7 ng × h/ml (p=0.160. Bioavalability of SC palonosetron was 118% (95% IC: 69-168. Cmax was lower with SC than with IV route and was reached 15 minutes following SC administration. CONCLUSIONS: Palonosetron bioavailability was similar when administered by either SC or IV route. This new route of administration might be specially useful for outpatient management of emesis and for administration of oral chemotherapy. TRIAL REGISTRATION: ClinicalTrials.gov NCT01046240.

    Ovarian cancer is routinely treated with surgery and platinum-based chemotherapy. Resistance is a major obstacle in the efficacy of this chemotherapy regimen and the ability to identify those patients at risk of developing resistance is of considerable clinical importance. The expression of calpain-1, calpain-2 and calpastatin were determined using standard immunohistochemistry on a tissue microarray of 154 primary ovarian carcinomas from patients subsequently treated with platinum-based adjuvant chemotherapy. High levels of calpain-2 expression was significantly associated with platinum resistant tumours (P = 0.031). Furthermore, high expression of calpain-2 was significantly associated with progression-free (P = 0.049) and overall survival (P = 0.006) in this cohort. The association between calpain-2 expression and overall survival remained significant in multivariate analysis accounting for tumour grade, stage, optimal debulking and platinum sensitivity (hazard ratio = 2.174; 95% confidence interval = 1.144–4.130; P = 0.018). The results suggest that determining calpain-2 expression in ovarian carcinomas may allow prognostic stratification of patients treated with surgery and platinum-based chemotherapy. The findings of this study warrant validation in a larger clinical cohort. PMID:22435971

    Purpose Clinical features characteristic of small-cell prostate carcinoma (SCPC), (““anaplastic””) often emerge during the progression of prostate cancer. We sought to determine the efficacy of platinum-based chemotherapy in patients meeting at least one of seven prospectively defined “anaplastic” clinical criteria, including exclusive visceral or predominantly lytic bone metastases, bulky tumor masses, low PSA levels relative to tumor burden or short response to androgen deprivation therapy. Experimental Design A 120-patient phase II trial of frontline carboplatin and docetaxel (CD) and second-line etoposide and cisplatin (EP) was designed to provide reliable clinical response estimates under a Bayesian probability model with early stopping rules in place for futility and toxicity. Results Seventy-four of 113 (65.4%) and 24 of 71 (33.8%) were progression free after 4 cycles of CD and EP, respectively. Median overall survival (OS) was 16 months (95% CI, 13.6-19.0 months). Of the 7 “anaplastic” criteria, bulky tumor mass was significantly associated with poor outcome. Lactic acid dehydrogenase (LDH) strongly predicted for OS and rapid progression. Serum carcinoembryonic antigen (CEA) concentration strongly predicted OS but not rapid progression. Neuroendocrine markers did not predict outcome or response to therapy. Conclusion Our findings support the hypothesis that patients with “anaplastic” prostate cancer are a recognizable subset characterized by a high response rate of short duration to platinum-containing chemotherapies, similar to SCPC. Our results suggest that CEA is useful for selecting therapy in men with CRPC and consolidative therapies to bulky high-grade tumor masses should be considered in this patient population.

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

Methods: Patients receiving platinum-based doublets in the first-line setting for AdvNS-NSCLC from 2010 to 2012 in two Chinese tertiary hospitals were identified to create the retrospective study cohort. Propensity score methods were used to create matched treatment groups for head-to-head comparisons on HCTC between pemetrexed–platinum and other platinum-based doublets. Multiple linear regression analyses were performed to rank studied platinum-based doublets for their associations with the log10 scale of HCTC for nonchemotherapy drugs and nondrug care. Results: Propensity score methods created matched treatment groups for pemetrexed–platinum versus docetaxel–platinum (61 pairs, paclitaxel–platinum (39 pairs, gemcitabine–platinum (93 pairs, and vinorelbine–platinum (73 pairs, respectively. Even though the log10 scale of HCTC for nonchemotherapy drugs and nondrug care associated with pemetrexed–platinum was ranked lowest in all patients (coefficient –0.174, P=0.015, which included patients experiencing

    Assuming that tumor cell dissemination requires a shift to a mesenchymal phenotype, we analyzed the incidence of epithelial-to-mesenchymal-transition (EMT)-like circulating tumor cells (CTCs) in ovarian cancer patients and inquired, how their molecular phenotypes respond to platinum-based chemotherapy and influence outcome. Before surgery, overall detection rate for epithelial CTCs was 18%. EMT-like CTCs were more frequently observed (30%) and were mutually exclusive to epithelial CTCs in the majority of patients (82%). After chemotherapy, EMT-like CTCs increased up to 52%, accompanied by the "de novo" emergence of PI3Kα+/Twist+ EMT-like CTCs. Before surgery, PI3K+ EMT-like CTCs in combination with epithelial CTCs indicated decreased OS (p = 0.02) and FIGO I-III patients with residual tumor burden after surgery were more likely to be positive for EMT-like CTCs after chemotherapy (p = 0.02). In the latter group, epithelial CTCs alone significantly correlated with decreased PFS and OS (p = 0.02, p = 0.002), supported by an additional inclusion of PI3K+ CTCs (OS, p = 0.001). Blood samples of 91 ovarian cancer patients before surgery and 31 matched samples after adjuvant chemotherapy were evaluated for CTCs with the AdnaTest ovarian cancer and EMT-1, analyzing the epithelial-associated transcripts EpCAM, Muc-1 and CA125 and the EMT-associated transcripts PI3Kα, Akt-2 and Twist. Platinum-based chemotherapy seems to select for EMT-like CTCs in ovarian cancer patients and provokes a shift towards PI3Kα and Twist expressing CTCs, which may reflect clonal tumor evolution towards therapy resistance. It has to be determined, whether this CTC subgroup may serve as a biomarker to identify patients at high risk.

    Polymorphisms of DNA repair genes may affect the repair capacity of DNA damages and cause different responses towards chemotherapy. Excision repair cross-complementing group 2 (ERCC2) plays an important role in the nucleotide excision repair. The aim of this study was to investigate the association between ERCC2 single nucleotide polymorphisms (SNPs) and the response to platinum-based chemotherapy among patients with triple negative breast cancer. In total, 60 triple negative breast cancer patients treated with platinum-based chemotherapy were studied. The clinical, pathological and treatment data of them were collected. Sequenom's MassARRAY system was used in the detection of the SNPs of ERCC2. Finally, the association between genotypes and different clinical responses among patients was analyzed. All of the patients received a platinum-based chemotherapy for 4 cycles in median and achieved an overall response rate of 66.7%, showing a comparative good response towards platinum-based chemotherapy among triple negative breast cancer. Fifty-three of the 60 patients had got the results of ERCC2 rs1799793 polymorphisms after MassARRAY detection. The proportion of GG genotype and GA genotype was 81.1% and 18.9% respectively. The response rate of the rs1799793 GG genotype group was 69.8%, while the GA genotype group only had a response rate of 30.0%. It turned out that the GG genotype was associated with better response towards platinum-based chemotherapy (P=0.030). ERCC2 rs1799793 polymorphism may be associated with the clinical sensitivity of platinum-based chemotherapy and could be a potential predictive biomarker for triple negative breast cancer patients treated with platinum compounds.

    The efficacy of chemotherapeutic treatment of colorectal cancer is challenged by severe gastrointestinal side effects, which include nausea, vomiting, constipation, and diarrhea. These symptoms can persist long after the treatment has been ceased. An emerging concept is the ability of platinum-based drugs to stimulate immunity, which is in contrast to conventional chemotherapeutic agents that are immunosuppressive. Here, we review the immunomodulatory aspects of platinum-based anticancer chemotherapeutics and their impact on gastrointestinal innervation. Given the bidirectional communication between the enteric nervous system and gastrointestinal immune system; exploring the consequences of platinum-induced immunogenicity will facilitate better understanding of gut dysfunction caused by chemotherapeutic agents. We propose that the development of future successful chemotherapeutics should rely on targeting the mechanisms underlying long-term gastrointestinal side effects.

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

    Lung cancer is the leading cause of tumor-derived death. Although target therapy is proven very efficient, traditionally platinum-based chemotherapies are still primary treatment for most patients. Platinum can suppress the tumor growth and impair normal cells together. The primary aim of the present study was to study the potential role of translesion synthesis (TLS) that might play in platinum-chemotherapy tolerance and side-effect. In present study, a total of 663 patients who were newly histologically diagnosed with advanced NSCLC (aNSCLC) were enrolled. Treatment response was classified into four categories: complete response, partial response, stable disease, and progressive disease. Incidence of gastrointestinal and hematological toxicities was assessed twice a week during the whole first-line treatment. Eleven SNPs of POLK were genotyped. The associations between SNPs and treatment response or toxicity were analyzed with logistic regression model. Cox regression was used for survival analysis between SNPs and progression-free survival or overall survival. We identified that rs3213801 and rs5744533 showed complete linkage in the present study, and they were significantly associated with treatment response (adjusted P = 0.044), together with rs5744655 (adjusted P = 0.039). rs1018119 was correlated with gastrointestinal toxicity in smokers specially (adjusted P = 0.041). Besides, rs3756558 was associated with hematological toxicity and overall toxicity in smokers and combined cohort with additive model. We also identified the significant association between two SNPs, rs10077427 and rs5744545, and PFS. The polymorphism of POLK, an important gene in TLS, participates in platinum-chemotherapy tolerance and side-effect.

    Abstract The present observational cohort study was designed to elucidate the efficacy and safety profile of bevacizumab or cetuximab with chemotherapy as the first-line treatment in Chinese patients with metastatic colorectal cancer (mCRC). Clinical data were collected from a single-center registry study where mCRC patients received first-line fluoropyrimidine-based chemotherapy combined with either bevacizumab (188 patients with KRAS wild-type or mutated tumors) or cetuximab (101 patients with KRAS wild-type tumors) between January 2009 and December 2013. The Kaplan–Meier method was used for survival analysis. Cox proportional hazards model was used for estimating the prognostic and predictive values of clinicopathological characteristics. No statistically significant difference was observed between the bevacizumab and cetuximab groups in terms of median progression-free survival (PFS) (10.6 vs 8.7 months, P = 0.317), median overall survival (OS) (27.7 vs 28.3 months, P = 0.525), or overall response rate (43.1% vs 53.5%, P = 0.108). For the subset of patients with peritoneal dissemination, bevacizumab-based triplet appears to be superior to cetuximab-based triplet as measured by PFS (9.6 vs 6.1 months) and OS (26.3 vs 12.7 months), but not for patients without peritoneal dissemination (PFS, 10.6 vs 9.1 months; OS, 27.9 vs 30.7 months) (all unadjusted and adjusted interaction P < 0.05). Our study suggests that bevacizumab- or cetuximab-based regimens have similar effectiveness as first-line treatment of mCRC in Chinese population. Patients with peritoneal dissemination were likely to gain more benefit from bevacizumab than cetuximab treatment. Future prospective studies are required to further confirm these results.

    In the past decade, the advent of the epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) has dramatically influenced the therapeutic strategies for treating lung cancer, but with tumor progression and drug resistance, patients will ultimately develop reduced sensitivity to EGFR-TKIs. How can we delay the emergence of drug resistance? What is the next strategy after drug resistance? How to reasonably combine platinum-based chemotherapy and EGFR-TKIs? These questions are currently the focus of lung cancer research. Clinical studies have reported that platinum-based chemotherapy can increase the sensitivity to EGFR-TKIs. However, results of pre-clinical and clinical studies have been inconsistent. The mechanisms of platinum chemotherapy and EGFR-TKIs are still unknown due to the lack of systematic research. Therefore, systematic studies are required to show the mechanisms of EGFR-TKIs and chemotherapy agents and define the markers sensitive to their combinations when given concurrently or sequentially.

    Although adjuvant platinum-based chemotherapy improves survival in completely resected non-small cell lung cancer (NSCLC), its effect is limited. We evaluated whether the expression of heat shock protein 70 (Hsp70) is associated with clinical outcomes in patients with completely resected NSCLC who were treated with or without adjuvant platinum-based chemotherapy. Patients who underwent curative resection for NSCLC and diagnosed as stage IIA through IIIA were included. Immunohistochemical staining for Hsp70 was performed on surgical specimens and survival rates were compared by Hsp70 expression and adjuvant platinum-based chemotherapy. Of 327 enrolled patients, Hsp70 expression was positive in 220 (67.3%). For patients who did not receive adjuvant chemotherapy, Hsp70 expression did not significantly affect survival. However, for patients who received adjuvant chemotherapy, those with Hsp70-positive tumors had a longer disease-free survival outcome than cases with Hsp70-negative tumors (not reached vs. 27.3 months; P=0.002), although there was no significant difference in overall survival (97.0 vs. 58.9 months, P=0.080). In the adjuvant chemotherapy group, multivariate modeling showed that patients with Hsp70-postitive tumors had a lower risk of recurrence and death after adjusting for age, sex, performance status, pathologic stage, and histological type (disease-free survival: adjusted hazard ratio, 0.537; 95% CI, 0.362-0.796; P=0.002; overall survival: adjusted hazard ratio, 0.663; 95% CI, 0.419-1.051; P=0.080). Hsp70 is a positive predictive factor in completely resected NSCLC with received platinum-based adjuvant chemotherapy. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Squalamine, an antiangiogenic aminosterol, is presently undergoing Phase II clinical trials in cancer patients. To broaden our understanding of the clinical potential for squalamine, this agent was evaluated in nu/nu mouse xenograft models using the chemoresistant MV-522 human non-small cell lung carcinoma and the SD human neuroblastoma lines. Squalamine was studied alone and in combination with either cisplatin or paclitaxel plus carboplatin. Squalamine alone produced a modest MV-522 tumor growth inhibition (TGI) and yielded a TGI with cisplatin that was better than cisplatin alone. Squalamine also significantly enhanced the activity of paclitaxel/carboplatin combination therapy in the MV-522 tumor model. Squalamine similarly improved the effectiveness of cisplatin in producing TGI when screened against the SD human neuroblastoma xenograft. Xenograft tumor shrinkage was seen for the MV-522 tumor in combination treatments including squalamine, whereas no tumor shrinkage was seen when squalamine was omitted from the treatment regimen. To gain a greater understanding of the mechanism by which squalamine inhibited tumor growth in the xenograft studies, in vitro experiments were carried out with vascular endothelial growth factor-stimulated human umbilical vein endothelial cells in culture exposed to squalamine. Squalamine treatment was found to retard two cellular events necessary for angiogenesis, inducing disorganization of F-actin stress fibers and causing a concomitant reduction of detectable cell the surface molecular endothelial cadherin (VE-cadherin). We propose that the augmentation by squalamine of cytotoxicity from platinum-based therapies is attributable to interference by squalamine with the ability of stimuli to promote endothelial cell movement and cell-cell communication necessary for growth of new blood vessels in xenografts after chemotherapeutic injury to the tumor.

Methods: From 2002 to 2011 seventy- four consecutive patients with advanced or metastatic CRC, treated in UMHAT- Dr. G. Stranski, Department of Medical Oncology entered the study. Some patient’s characteristics, hematological and pathological parameters, were evaluated for their role as predictors of overall survival. The therapeutic regimens included FOLFOX or FOlFIRI. Survival analysis was evaluated by Kaplan- Meier test. The influence of pretreatment characteristics as prognostic factor for survival was analyzed using multivariate stepwise Cox regression analyses. Results: In multivariate analysis a significant correlation was exhibited between survival, poor performance status and multiple sites of metastasis. Variables significantly associated with overall survival in univariate analysis were performance status>1, thrombocytosis, anemia and number of metastatic sites >1. Conclusion: These results indicated that poor performance status, anemia, thrombocytosis as well as multiple site of metastasis could be useful prognostic factors in patients with metastatic CRC.

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

Published evidence has shown controversial results about the relationship between XRCC3 Thr241Met polymorphism and clinical outcomes of non-small cell lung cancer (NSCLC patients receiving platinum-based chemotherapy. METHODS: A systematic review and meta-analysis was performed to evaluate the predictive value of XRCC3 Thr241Met polymorphism on clinical outcomes of advanced NSCLC receiving platinum-based chemotherapy. Response to chemotherapy, overall survival (OS and progression-free survival (PFS were analyzed. RESULTS: A number of 11 eligible studies were identified according to the inclusion criteria. Carriers of the variant XRCC3 241Met allele were significantly associated with good response to platinum-based chemotherapy (ThrMet/MetMet vs. ThrThr: OR  = 1.509, 95% CI: 1.099-2.072, Pheterogeneity  = 0.618. The XRCC3 Thr241Met polymorphism was not associated with OS (MetMet vs. ThrThr, HR  = 0.939, 95% CI:0.651-1.356, Pheterogeneity  = 0.112 or PFS (MetMet vs. ThrThr, HR  = 0.960, 95% CI: 0.539-1.710, Pheterogeneity  = 0.198. Additionally, no evidence of publication bias was observed. CONCLUSIONS: This systematic review and meta-analysis shows that carriers of the XRCC3 241Met allele are associated with good response to platinum-based chemotherapy in advanced NSCLC, while the XRCC3 Thr241Met polymorphism is not associated with OS or PFS.

    Full Text Available Abstract Malignant Mesothelioma is an uncommon and very aggressive tumor that accounts for 1% of all the deaths secondary to malignancy in humans. Interestingly, this neoplasm has been occasionally described in companion animals as well. Aim of this study was the preclinical evaluation of the combination of piroxicam with platinum-based intracavitary chemotherapy in pets. Three companion animals have been treated in a three years period with this combination. Diagnosis was obtained by ultrasonographic exam of the body cavities that evidenced thickening of the mesothelium. A surgical biopsy further substantiated the diagnosis. After drainage of the malignant effusion from the affected cavity, the patients received four cycles of intracavitary CDDP at the dose of 50 mg/m2 every three weeks if dogs or four cycles of intracavitary carboplatin at the dose of 180 mg/m2 (every 3 weeks if cats, coupled with daily administration of piroxicam at the dose of 0.3 mg/kg. The therapy was able to arrest the effusion in all patients for variable remission times: one dog is still in remission after 3 years, one dog died of progressive disease after 8 months and one cat died due to progressive neoplastic growth after six months, when the patient developed a mesothelial cuirass. The combination showed remarkable efficacy at controlling the malignant effusion secondary to MM in our patients and warrants further investigations.

    Reactive oxygen species modulator 1 (Romo1) is a key mediator of intracellular reactive oxygen species production. However, examination of the clinical usefulness of Romo1 in cancers has been limited. We evaluated the association of Romo1 expression with clinical outcomes in advanced non-small cell lung cancer (NSCLC) patients treated with platinum-based chemotherapy. Romo1 expression in tumor tissue was examined by immunohistochemistry and evaluated by histological score. Survival analyses were performed according to Romo1 expression and the association between Romo1 expression and clinical parameters was evaluated. A total of 88 tumor specimens were analyzed. Significantly shorter median progression-free survival (PFS) was observed in the high Romo1 group compared with the low Romo1 group (4.5 months vs. 9.8 months, p in advanced NSCLC patients treated with platinum-based chemotherapy. Romo1 could be a potential adverse predictive marker in this setting.

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

    In non-small cell lung cancer (NSCLC), the association between common EGFR mutations (Del EX19/L858R) with EGFR tyrosine kinase inhibitors (EGFR-TKIs) has been well established. However, this has not been investigated for rare EGFR mutations or their impact on treatment response and outcome to EGFR TKIs (primary objective) and chemotherapy (secondary objective). In an observational prospective cohort, we analyzed 188 NSCLC patients from Mexico, Colombia and Costa Rica with EGFR mutations. As a first line of treatment, 66.5% received platinum-based chemotherapy. All patients received TKIs in first-line treatment or after progression to chemotherapy. The clinical-pathological characteristics as well as the f of common and rare EGFR mutations associated with treatment response were analyzed. Of all patients, 79.5% had common and 20.5% had rare EGFR mutations. Lepidic and acinar adenocarcinomas were associated with common EGFR mutations (p=0.010). Patients with common EGFR mutations had higher response rates to EGFR-TKIs than those who had rare EGFR mutations (63.8 vs 32.4%, p<0.001). Women had increased progression-free survival (PFS) to EGFR-TKIs than men (16.4 vs 9.5 months, p=0.02). The median PFS and overall survival (OS) were better in patients with common EGFR mutations (15.5 vs 3.9 months, p<0.001; and 37.3 vs 17.4 months, p<0.001) respectively. Our findings suggested that only patients with rare EGFR mutations could receive platinum-based chemotherapy as a first-line treatment, due to their low response rates and short PFS in response to EGFR-TKIs. Consequently, EGFR-TKIs could be reserved as a second- or third-line treatment. In patients with EGFR mutations, women have better PFS to EGFR-TKIs than men, and rare EGFR mutations are more frequent in high grade adenocarcinomas than in low grade tumors.

    Abstract Background Non-small cell lung cancer (NSCLC) is the most common type of lung cancer and remains an important cause of cancer death worldwide. Platinum-based chemotherapy (PBC) for NSCLC can modify outcome while the risk of cardiotoxicity remains poorly researched. We aimed to evaluate the incidence and severity of cardiac injury during PBC in patients with NSCLC and to identify patients at risk. Methods This was a single-centre, prospective, observational study of patients with early and advanced stage NSCLC referred for PBC. In addition to standard care, patients were examined and evaluated for cardiotoxicity before the first dose (visit 1), at the last dose (visit 2) and 6 months after the last dose of PBC (visit 3). Cardiotoxicity (at visit 2 and 3) was defined as increase in the ultrasensitive troponin T, N-terminal pro-B type natriuretic peptide or decrease in left ventricular ejection fraction (LVEF). Results Overall, 41 patients (mean age 61 ± 9; 54% men; 68% advanced lung cancer) were included. The median number of PBC cycles was 4. During the study period, there were no incidents of heart failure, and 3 deaths caused by tumour progression were recorded. The mean values of biomarkers and LVEF did not change significantly (p > 0.20). However, 10 (25%) had cardiotoxicity which was independently associated with a history of ischemic heart disease (p = 0.026). Conclusions In NSCLC, cardiac assessment and lifestyle modifications may be pursued in patients with a history of cardiac disease and in patients with longer life expectancy.

    Full Text Available Objectives: Toxicity of cancer chemotherapy may be affected by nutritional status of patients which is reflected in the body mass index (BMI. We sought to assess whether the adverse drug reaction (ADR profile of platinum-based chemotherapy varies with BMI status. Materials and Methods: Adult patients of either sex, suffering from a solid tumor (lung, head and neck, ovary, gall bladder, stomach, colon and started on platinum-based chemotherapy as initial treatment were included. BMI at chemotherapy commencement was obtained from medical records. Events were recorded and graded as per Eastern Co-operative Oncology Group Common Toxicity Criteria-patients′ complaints; clinically evident signs and laboratory reports were considered. Frequencies of individual adverse events were compared between low BMI (<18.5 kg/m 2 and satisfactory BMI groups. Similar comparisons were done for events with grades 2 or 3 severities. Results: A total of 50 patients were observed over a 3-month period of whom 17 (34% belonged to the low BMI group. Nausea, vomiting, diarrhea, stomatitis, anemia, alopecia, tinnitus and paresthesia were the commonly observed ADRs. The frequencies of anemia (P = 0.152 and vomiting (P = 0.140 and severity of grades of nausea (P = 0.066, anemia (P = 0.120 and paresthesia (P = 0.128 showed a higher trend in the low BMI group though differences were not statistically significant. The frequencies of tinnitus (P = 0.021 and paresthesia overall (P = 0.036 were significantly higher in the low BMI group. Conclusion: ADR profile of primary platinum-based chemotherapy appears to be partly influenced by BMI. This suggests the importance of maintaining adequate nutrition in patients and the need for greater vigilance in those with low BMI.

    There is debate surrounding which treatment is superior in overall survival (OS) rates in patients with epidermal growth factor receptor (EGFR) mutant non-small cell lung cancer (NSCLC); first-line tyrosine kinase inhibitor (TKI) followed by second-line platinum-based doublet chemotherapy (PCT), or the reverse sequence. Cross treatment of first- and second-line TKI and PCT makes it difficult to deduce which sequence (TKI-PCT or PCT-TKI) is better for OS. Using the keywords “lung cancer” and “EGFR” we identified clinical trials within the PubMed database which were published between January 2006 and November 2016. Basic characteristics and OS with hazard ratio and 95% confidence intervals were searched and analyzed. In total, 457 articles were reviewed and nine clinical trials with 1,876 patients were of sufficient quality for further analysis. Fixed effects models were performed to pool the data in this meta-analysis. All nine studies were open-labeled, multicenter, Phase III randomized controlled clinical trials. The pooled hazard ratio was 0.96 (95% confidence interval: 0.84–1.10) for OS between first-line TKI followed by second-line PCT compared to the reverse sequence. No statistically significant heterogeneity (I2=0, P=0.553) nor publication bias (Egger’s P=0.991) was observed among these studies. In conclusion, there was no OS benefit between first-line TKI followed by second-line PCT compared to the reverse sequence in EGFR mutant NSCLC patients. Chemotherapy was still useful and irreplaceable for the treatment of NSCLC, especially for those patients with EGFR unavailable for testing. PMID:28280362

The purpose of this study was to investigate the association between TIMP-1 and objective response to chemotherapy in an independent patient population consisting of patients with metastatic breast cancer from Sweden and Denmark. TIMP-1 was measured using ELISA in 162 primary tumor extracts from...... patients who later developed metastatic breast cancer and these levels were related to the objective response to first-line chemotherapy. Increasing levels of TIMP-1 were associated with a decreasing probability of response to treatment, reaching borderline significance (OR = 1.59, 95% CI: 0.97-2.62, P = 0...

    This is an update of a Cochrane review that was first published in Issue 1, 2009. Gestational trophoblastic neoplasia (GTN) is a rare but curable disease arising in the fetal chorion during pregnancy. Most women with low-risk GTN will be cured by evacuation of the uterus with or without single-agent chemotherapy. However, chemotherapy regimens vary between treatment centres worldwide and the comparable benefits and risks of these different regimens are unclear.

    Abstract Background: Ovarian cancer (OC) is the 5th leading cause of cancer-related deaths around the world, and several chemotherapy regimens have been applied in the treatment of OC. We aim to compare toxicities of different chemotherapy regimens in the treatment of advanced ovarian cancer (AOC) using network meta-analysis. Methods: Literature research in Cochrane Library, PubMed, and EMBASE was performed up to November 2015. Eligible randomized controlled trials (RCTs) of different chemotherapy regimens were included. Network meta-analysis combined direct and indirect evidence to assess pooled odds ratios (ORs) and draw the surface under the cumulative ranking (SUCRA) curves. Results: Thirteen eligible RCTs were included in this network meta-analysis, including 8 chemotherapy regimens (paclitaxel + carboplatin [PC], pegylated liposomal doxorubicin [PLD] + carboplatin, carboplatin, gemcitabine + carboplatin, paclitaxel, PC + epirubicin, PC + topotecan, docetaxel + carboplatin). Gemcitabine + carboplatin regimen exerted higher incidence of anemia when compared with carboplatin and paclitaxel regimens. The incidence of febrile neutropenia of gemcitabine + carboplatin regimen was higher than that of PC, PLD + carboplatin, carboplatin, and PC + topotecan regimens. Topotecan PC + epirubicin regimen had a higher toxicity, comparing with PC, PLD + carboplatin, and PC + topotecan regimens. As for thrombocytopenia, gemcitabine + carboplatin chemotherapy regimen produced an obviously higher toxicity than PC and carboplatin. As for nausea, PLD + carboplatin chemotherapy regimen had a significantly higher toxicity than that of carboplatin chemotherapy regimen. Moreover, when compared with PC and carboplatin chemotherapy regimens, the toxicity of PC + epirubicin was greatly higher to patients with AOC. Conclusion: The nonhematologic toxicity of PLD + carboplatin regimen was higher than other regimens, which

    Whether fluorine-18-fluorodeoxyglucose ((18)F-FDG) uptake within tumor cells differs between primary and recurrent lung cancers is unknown. The aim of this study was to investigate the prognostic significance of (18)F-FDG uptake by comparing that measured preoperatively at the primary site to that measured postoperatively at sites of non-small cell lung cancer (NSCLC) recurrence. Only patients with postoperative recurrences who received platinum-based chemotherapy as the initial treatment after recurrence were included in the study. Fifty-two patients underwent (18)F-FDG positron emission tomography (PET) examinations before thoracotomy and at the time of recurrence after curative surgery. All recurrences were treated with platinum-based chemotherapy. (18)F-FDG uptake in the preoperative primary tumors was significantly higher than that in the recurrent tumors (p=0.028), demonstrating a statistically significant correlation (Pearson's correlation coefficient γ=0.482, precurrence. In NSCLC patients treated by chemotherapy for recurrence, preoperative measurements of (18)F-FDG uptake may be a more powerful surrogate marker for predicting outcome when measured preoperatively at the primary tumor site rather than postoperatively at sites of recurrence. © 2013 Published by The Japanese Respiratory Society on behalf of The Japanese Respiratory Society.

    Colorectal cancer liver metastasis (CRLM) is a refractory disease after failure of first-line or second-line chemotherapy. Bevacizumab is recommended as first-line therapy for advanced colorectal cancer, but is unproven in CRLM through the hepatic artery. We report favorable outcomes with targeted vessel regional chemotherapy (TVRC) for liver metastatic gastric cancer. TVRC with FOLFOX and bevacizumab perfusion through the hepatic artery was attempted for CRLM for efficacy and safety evaluation. In a single-institution retrospective observational study, 246 patients with CRLM after at least first-line or second-line failure of systemic chemotherapy received TVRC with FOLFOX (i.e. oxaliplatin, leucovorin, and 5-fluorouracil). Of 246 patients, 63 were enrolled into two groups: group 1 (n=30) received bevacizumab and TVRC following tumor progression during previous TVRC treatments; group 2 (n=33) received TVRC plus bevacizumab for CRLM on initiating TVRC. There were no significant differences in the median survival time (14.7 vs. 13.2 months, P=0.367), although the median time to progression was significant (3.3 vs. 5.5 months, P=0.026) between groups. No severe adverse events related to TVRC plus bevacizumab perfusion occurred. Target vessel regional chemotherapy with FOLFOX plus bevacizumab perfusion through the hepatic artery was effective and safe in CRLM. The optimal combination of TVRC and bevacizumab needs further confirmation in future phase II-III clinical trials.

    The aim of present study was to investigate the role of preoperative neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) used as prognostic markers for predicting chemotherapeutic response and survival outcomes in patients with epithelial ovarian cancer (EOC) who are receiving platinum-based chemotherapy. A total of 344 patients diagnosed with EOC who are receiving platinum-based chemotherapy from 2005 to 2010 in the hospital were enrolled. NLR and PLR were calculated from complete blood cell count taken before operation. The patients were divided into platinum-resistant (P-R) group and platinum-sensitive (P-S) group according to chemotherapeutic response. Clinicopathologic variables and outcomes were retrospectively collected and compared among groups. We used receiver operating characteristic (ROC) curves to calculate optimal cut-off values for NLR and PLR to predict chemotherapeutic response and prognosis. The AUC, sensitivity, specificity of NLR > 3.02 to predict platinum resistance were 0.819, 75.0% and 81.45%, respectively. The corresponding values of PLR > 207 were 0.727, 60.42% and 85.48%, respectively. Patients with lower value of NLR (NLR platinum resistance in patients with EOC.

    To carry out a cost-minimization analysis including a comparison of the costs arising from first-line treatment by trastuzumab plus docetaxel versus trastuzumab plus paclitaxel in patients with metastatic breast cancer. All consecutive patients with human epidermal growth receptor 2-postive metastatic breast cancer who were treated at Besançon University Hospital and Saint Vincent private hospital between 2001 and 2010 by first-line therapy containing trastuzumab plus taxane were retrospectively studied. Economic analysis took into account costs related to drugs, hospitalization, and healthcare travel. Progression-free survival difference between the two treatments was not significant (p = 0.65). First-line treatment by trastuzumab plus taxane was estimated at approximately €68,000 (p = 0.74). The drug costs represented around 70-75% of the total cost, mainly related to the use of trastuzumab. Our economic analysis shows that although the costs of the two trastuzumab plus taxane regimens are similar, they may contribute to the on-going debate about the availability and use of innovative chemotherapy drugs, in particular in human epidermal growth factor receptor 2-positive metastatic breast cancer with new therapies such as trastuzumab-DM1 and pertuzumab. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available Abstract Background The molecular characteristics associated with the response to treatment in glioblastomas (GBMs remain largely unknown. We performed a retrospective study to assess the genomic characteristics associated with the response of GBMs to either first-line chemotherapy or radiation therapy. The gene expression (n = 56 and genomic profiles (n = 67 of responders and non-responders to first-line chemotherapy or radiation therapy alone were compared on Affymetrix Plus 2 gene expression arrays and BAC CGH arrays. Results According to Verhaak et al.'s classification system, mesenchymal GBMs were more likely to respond to radiotherapy than to first-line chemotherapy, whereas classical GBMs were more likely to respond to first-line chemotherapy than to radiotherapy. In patients treated with radiation therapy alone, the response was associated with differential expression of microenvironment-associated genes; the expression of hypoxia-related genes was associated with short-term progression-free survival ( 10 months. Consistently, infiltration of the tumor by both CD3 and CD68 cells was significantly more frequent in responders to radiotherapy than in non-responders. In patients treated with first-line chemotherapy, the expression of stem-cell genes was associated with resistance to chemotherapy, and there was a significant association between response to treatment and p16 locus deletions. Consistently, in an independent data set of patients treated with either radiotherapy alone or with both radiotherapy and adjuvant chemotherapy, we found that patients with the p16 deletion benefited from adjuvant chemotherapy regardless of their MGMT promoter methylation status, whereas in patients without the p16 deletion, this benefit was only observed in patients with a methylated MGMT promoter. Conclusion Differential expression of microenvironment genes and p16 locus deletion are associated with responses to radiation therapy and to first-line

    LDH may represent an indirect marker of neo-angiogenesis and worse prognosis in many tumour types. We assessed the correlation between LDH and clinical outcome for biliary tract cancer (BTC) patients treated with first-line chemotherapy. Overall, 114 advanced BTC patients treated with first-line gemcitabine and cisplatin were included. Patients were divided into two groups (low vs. high LDH), according to pre-treatment LDH values. Patients were also classified according to pre- and post-treatment variation in LDH serum levels (increased vs. decreased). Median progression free survival (PFS) was 5.0 and 2.6 months respectively in patients with low and high pre-treatment LDH levels (p = 0.0042, HR = 0.56, 95% CI: 0.37-0.87). Median overall survival (OS) was 7.7 and 5.6 months (low vs. high LDH) (p = 0.324, HR = 0.81, 95% CI: 0.54-1.24). DCR was 71% vs. 43% (low vs. high LDH) (p = 0.002). In 38 patients with decreased LDH values after treatment, PFS and OS were respectively 6.2 and 12.1 months, whereas in 76 patients with post-treatment increased LDH levels, PFS and OS were respectively 3.0 and 5.1 months (PFS: p = 0.0009; HR = 0.49; 95% IC: 0.33-0.74; OS: p < 0.0001; HR = 0.42; 95% IC: 0.27-0.63). Our data seem to suggest that LDH serum level may predict clinical outcome in BTC patients receiving first-line chemotherapy.

  15. [Efficacy of first-line afatinib versus chemotherapy in EGFR mutation positive pulmonary adenocarcinoma].

    2014-12-01

    Therapy of patients with advanced NSCLC has lately changed due to the algorithm based on the presence or absence of oncogenic mutations. There is an agreement nowadays that in the presence of activating EGFR mutations, the administration of EGFR TKI (gefitinib, erlotinib, afatinib) is the most efficacious initial treatment. Unlike the first-generation TKIs, afatinib is a new, irreversible ErbB blocker, selectively and effectively blocking signals from the ErbB family receptors. Afatinib's marketing authorization is based on a large, randomized, phase III clinical trial, LUX-Lung 3, where patients in the control arm were treated with the best available chemotherapy (pemetrexed/cisplatin combination). Primary endpoint was progression-free survival (PFS). Patients with common EGFR mutations showed a PFS of 13.6 months when treated with afatinib, while treatment in the control arm resulted in a PFS of 6.9 months. Overall survival (OS) was 31.6 and 28.2 months, respectively. LUX-Lung 3 has been followed by the LUX-Lung 6 trial, comparing afatinib treatment to traditional chemotherapy (gemcitabine/cisplatin) in Asian patients with NSCLC harboring EGFR mutations. This clinical trial has also proved benefit of afatinib: PFS was 11.0 months in the afatinib arm and 5.6 months in the control arm by independent reviewer, while OS was 23.6 months and 23.5 months, respectively. Similarity of the OS values in both trials is explained by the cross-over treatment. When further analyzing OS data, a statistically significant difference between the afatinib and the control arm was seen in the EGFR exon 19 del subgroup (LUX-Lung 3: 33.3 vs. 21.1 months, LUX-Lung 6: 31.4 vs. 18.4 months, respectively).

    Full Text Available Long non-coding RNA (lncRNA CASC8 rs10505477 polymorphism has been identified to be related to risk of many kinds of cancers, such as colorectal cancer, gastric cancer, and invasive ovarian cancer, and it may be involved in the prognosis of gastric cancer patients who have received platinum-based chemotherapy after surgical treatment. So far, there is no study investigating the clinical significance of lncRNA CASC8 rs10505477 in lung cancer susceptibility and treatment. In this study, we genotyped 498 lung cancer patients and 213 healthy control subjects to explore the correlation between the rs10505477 polymorphism and lung cancer risk in a Chinese population. Among the 498 patients, 467 were selected for the chemotherapy response and toxicity study. We found that the single nucleotide polymorphisms (SNP rs10505477 was greatly related to lung cancer risk in male and adenocarcinoma subgroups in recessive model (adjusted OR = 0.51, 95%CI = 0.29–0.90, p = 0.02; adjusted OR = 0.52, 95%CI = 0.30–0.89, p = 0.02, respectively. It was also closely correlated with platinum-based chemotherapy response in dominant model (adjusted OR = 1.58, 95%CI = 1.05–2.39, p = 0.03. Additionally, we observed that CASC8 rs10505477 polymorphism was significantly relevant to severe hematologic toxicity in non-small-cell lung cancer (NSCLC subgroup in dominant model (adjusted OR = 0.59, 95%CI = 0.35–0.98, p = 0.04 and in additive model (adjusted OR = 0.62, 95%CI = 0.43–0.90, p = 0.01. Furthermore, it was found that rs10505477 polymorphism was greatly associated with gastrointestinal toxicity in SCLC and cisplatin subgroups in dominant model (adjusted OR = 7.82, 95%CI = 1.36–45.07, p = 0.02; adjusted OR = 1.94, 95%CI = 1.07–3.53, p = 0.03, respectively. Thus, lncRNA CASC8 rs10505477 could serve as a possible risk marker for diagnosing lung cancer, and could be used to forecast the response and toxicity of platinum-based treatment in lung cancer patients.

    Background: Combination chemotherapy is accepted as a high efficacy treatment for gastric cancer, whereas choice of standard treatment is unclear. Multiple chemotherapeutic regimens have been used to achieve higher efficacy and lower toxicity. This study was designed to evaluate the treatment results of advanced gastric cancer with Capecitabine and Oxaliplatin regimen. Subjects and Methods : All cases with documented gastric adenocarcinoma and advanced disease were candidates for receiving Xelox regimen (Capecitabine – 750 mg/m2/twice daily/ 1-14 days and Oxaliplatin 125 mg/m2 in 1st day). Results: Twenty five cases with advanced gastric cancer entered in study while 24 cases continued treatment protocol and were evaluated. Mean age was 59.5 ± 12.1 years (range: 20-75), male and female cases were 66.7% and 33.3%, respectively. All cases received at least four cycles of Xelox regimen. Overall response rate was 74.99% with 29.16% complete response. Overall survival rate was 13 ± 0.53 months and DFS (disease-free survival) was 6 ± 1.09 months. Extremities neuropathy (62.5%), headache (45.8%) and muscle cramps (29.2%) were the most common complains. Haematological changes were rare and 16.7% of cases had mild cytopenia. Treatment related death was not observed. Conclusion: Xelox regimen is a safe and highly effective first line treatment for gastric cancer; however, considering it as first line therapy needs larger studies. PMID:27928475

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

    Objective:The combination of hepatic arterial chemotherapy (HAIC) and systemic chemotherapy (SYC) has potential ef ect on colorectal cancer (CRC) patients with unresectable hepatic metastasis. The aim of this retrospective study was to investigate the ef icacy and safety of this combined therapeutic regimen on Chinese patients based on single institute experiences. Methods:Al 54 patients of this retrospective analysis were diagnosed with CRC with unresectable liver metas-tasis and received combined HAIC and SYC. Among the patients, 23 of them received HAIC plus SYC when they developed liver metastases as first-line treatment (Group 1), and 31 patients received HAIC plus SYC as non-first-line treatment (Group 2). The dif erent ef icacy in two groups was analyzed by SPSS 19.0. Results:The overal response rate (ORR) were 52.2%and 25.8%respectively in Groups 1 and 2 (P=0.047), and the disease control rate (DCR) were 65.2%and 35.5%respec-tively in Groups 1 and 2 (P=0.031). The median progression-free survival (PFS) were 6.8 and 3.3 months (P=0.002), the median hepatic progression-free survival (H-PFS) were 8.8 and 3.7 months (P=0.001), and the median overal survival (OS) were 18.8 and 13.7 months (P=0.121) in Groups 1 and 2, respectively. No fatal reaction was observed and no significant dif erence of adverse reaction was found in two groups. Grade 3/4 toxic ef ects included neutropenia (9.7%in Group 2 only), gastrointestinal reaction (8.7%in Group 1 and 6.5%in Group 2), stomatitis (6.5%in Group 2 only) and hyperbilirubinemia (4.3%in Group 1 only). Conclusion:HAIC combined with SYC showed promising ef icacy and safe profiles on CRC patients with unresectable liver metastases.

    Full Text Available Abstract Background Bevacizumab has an important role in first-line treatment of metastatic colorectal cancer. However, clinical trials studying its effect have involved distinct chemotherapy regimens with divergent results. The aim of this meta-analysis is to gather current data and evaluate not only the efficacy of bevacizumab, but also the impact of divergent backbone regimens. Methods A wide search of randomized clinical trials using bevacizumab in first-line metastatic colorectal cancer was performed in Embase, MEDLINE, LILACS and Cochrane databases. Meeting presentations and abstracts were also investigated. The resulting data were examined and included in the meta-analysis according to the type of regimen. Results Six trials, totaling 3060 patients, were analyzed. There was an advantage to using bevacizumab for overall survival (OS and progression-free survival (PFS (HR = 0.84; CI: 0.77-0.91; P Conclusions Bevacizumab has efficacy in first-line treatment of advanced colorectal cancer, but the current data are insufficient to support efficacy in all regimens, especially infusional fluorouracil regimens, like FOLFIRI and FOLFOX.

    Fluoropyrimidine-based regimens are the most common treatments in advanced gastric cancer. We used a Bayesian network meta-analysis to identify the optimal fluoropyrimidine-based chemotherapy by comparing their relative efficacy and safety. We systematically searched databases and extracted data from randomized controlled trials, which compared fluoropyrimidine-based regimens as first-line treatment in AGC. The main outcomes were overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and grade 3 or 4 adverse events (AEs). A total of 12 RCTs of 4026 patients were included in our network meta-analysis. Pooled analysis showed S-1 and capecitabine had a significant OS benefit over 5-Fu, with hazard ratios of 0.90 (95%CI = 0.81-0.99) and 0.88 (95%CI = 0.80-0.96), respectively. The result also exhibited a trend that S-1 and capecitabine prolonged PFS in contrast to 5-Fu, with hazard ratios of 0.84 (95%CI = 0.66-1.02) and 0.84 (95%CI = 0.65-1.03), respectively. Additionally, all the three fluoropyrimidine-based regimens were similar in terms of ORR and grade 3 or 4 AEs. Compared with regimens based on 5-Fu, regimens based on S-1 or capecitabine demonstrated a significant OS improvement without compromise of AEs as first-line treatment in AGC in Asian population. S-1 and capecitabine can be interchangeable according their different emphasis on AEs.

    The phase III IUNO trial assessed the benefit of maintenance erlotinib versus erlotinib at progression in advanced/metastatic non-small-cell lung cancer (NSCLC) that had not progressed following four cycles of platinum-based chemotherapy. Patients had stage IIIB/IV NSCLC, no known epidermal growth factor receptor (EGFR)-activating mutation, and objective response or disease stabilization after platinum-based induction chemotherapy. Central EGFR-mutation testing was undertaken on tumors from patients with unknown or wild-type EGFR status following local testing. Patients were randomized to receive blinded maintenance erlotinib 150mg/day ('early erlotinib') or placebo. Those who progressed on placebo received open-label erlotinib ('late erlotinib'); patients who progressed on erlotinib received approved second-line chemotherapy or best supportive care. Primary endpoint: overall survival (OS). 643 patients were randomized to receive maintenance erlotinib (n=322) or placebo (n=321). As of March 23, 2015, 242 (75.2%) OS events had occurred with 'early erlotinib' versus 235 (73.2%) with 'late erlotinib'. Median OS was 9.7 and 9.5 months with 'early erlotinib' and 'late erlotinib', respectively (HR, 1.02, 95% CI: 0.85-1.22; log-rank p=0.82). No progression-free survival, objective response rate, or disease control rate benefit was observed with maintenance erlotinib. 410 patients entered the second-line phase of the study: 160 patients (50%) from the maintenance erlotinib arm and 250 patients (78%) from the maintenance placebo arm. The pattern of adverse events (AEs) was consistent with previous trials; 11 patients who received blinded erlotinib and 3 who received placebo died during the blinded maintenance phase due to nontreatment-related AEs. OS with maintenance erlotinib was not superior to second-line treatment in patients whose tumor did not harbor an EGFR-activating mutation. Safety results were consistent with the established safety profile of erlotinib. Thus

Methods: We retrospectively reviewed patients who had received second-line docetaxel-based chemotherapy for advanced ESCC in Zhejiang Cancer Hospital between January 2008 and December 2011. Survival curves were plotted using the Kaplan–Meier method. The Cox proportional hazard model was used for multivariate analysis. Results: Eighty-five patients received docetaxel-based second-line chemotherapy after the failure of first-line fluorouracil-based treatment. Forty-four patients received docetaxel-platinum chemotherapy, and 41 received docetaxel single-agent treatment. The progression-free survival (PFS and overall survival (OS were 3.5 and 5.5 months in all of the patients, respectively. There were no statistically significant differences in PFS and OS between docetaxel-platinum and docetaxel single-agent chemotherapy groups (P-value 0.38 and 0.64, respectively. Response to first-line chemotherapy was a favorable prognostic factor for PFS in uni- and multivariate analyses (P-value 0.005 and 0.028, respectively. Conclusion: Patients with docetaxel-based second-line treatment obtained a moderate PFS advantage in advanced ESCC. Response to first-line chemotherapy was a favorable prognostic factor for PFS of second-line chemotherapy in advanced ESCC. Keywords: ESCC, efficacy, toxicity

    Aidi injection is an adjuvant chemotherapy drug commonly used in China. Can Aidi injection restore the cellular immunity and improve the clinical efficacy in non-small-cell lung cancer (NSCLC) patients treated with platinum-based chemotherapy? There is a lack of strong evidence to prove it. To further reveal it, we systematically evaluated all related studies. We collected all studies about the clinical efficacy and cellular immunity of Aidi injection plus platinum-based chemotherapy for NSCLC in Medline, Embase, Web of Science, China national knowledge infrastructure database (CNKI), Chinese Scientific Journals Full-Text Database (VIP), Wanfang, China biological medicine database (CBM) (established to June 2015), Cochrane Central Register of Controlled Trials (CCRCT) (June 2015), Chinese clinical trial registry, and US-clinical trials (June 2015). We evaluated their quality according to the Cochrane evaluation handbook of randomized controlled trials (RCTs) (5.1.0), extracted data following the patient intervention control group outcomes principles and synthesized the data by meta-analysis. Seventeen (RCTs) with 1390 NSCLC patients were included, with general methodological quality in most trials. The merged relative risk (RR) values and their 95% CI of meta-analysis for objective response rate (ORR) and disease control rate (DCR) were as follows: 1.26 (1.12, 1.42) and 1.11(1.04, 1.17). The merged standardized mean difference (SMD) values and their 95% CI of meta-analysis for the percentage of CD3T cells, CD4T cells, CD8T cells, natural killer (NK) cells, and CD4/CD8 T cell ratio were as follows: 1.41, (0.89, 1.92), 1.59, (1.07, 2.11), 0.85, (0.38, 1.33), 1.64 (0.89, 2.39) and 0.91, (0.58, 1.24). Compared with platinum-based chemotherapy alone, all differences were statistically significant. These results might be overestimated or underestimated. Aidi injection plus platinum-based chemotherapy can improve the clinical efficacy of patients with NSCLC. Aidi

    Full Text Available Background and objective It has been proven that the insulin-like growth factor 1 receptor (IGF-1R gene is an important regulator of many aspects of growth, differentiation, and development. The insulin-like growth factor 2 receptor (IGF-2R gene is a negative mediator for carcinogenesis. The aim of this study is to investigate the relationship of IGF-1R+1013(G/A and IGF-2R+1619(G/A single nucleotide polymorphism (SNP with platinum-based chemotherapy outcomes in advanced non-small cell lung cancer (NSCLC. Methods A total of 132 patients with NSCLC were routinely treated with platinum-based chemotherapy, and their clinical responses were evaluated after four cycles of chemotherapy. IGF-1R+1013(G/A and IGF-2R+1619(G/A were genotyped using polymerase chain reaction-restrictive fragment length polymorphism. The relationship between IGF-1R+1013(G/A and IGF-2R+1619(G/A genotypes and the clinical benefit rate, as well as the median survival time (MST, was analyzed. Results No significant association was found between IGF-1R+1013(G/A and IGF-2R+1619(G/A polymorphisms with clinical benefit (P>0.05. Further, we found that the two SNPs could not work together (P=0.975. The MST of patients with IGF-1R+1013(G/A genotypes with A allele (GA+AA was significantly shorter than that of GG genotype carriers (P=0.017. There was no significant difference in MST in patients with IGF-2R+1619(G/A A allele (GA+AA carrier and GG genotype carrier (P=0.575. The two SNPs showed a synergistic effect on MST. Patients who carried a mutant allele A of IGF-1R+1013(G/A and a mutant allele A of IGF-2R+1619(G/A had a MST of 12 months, which was significantly shorter than that of patients with other genotypes (P<0.05. Estimation by the Cox proportional hazards model showed that IGF-1R+1013(G/A polymorphism is an independent prognostic factor (P=0.020, and IGF-1R+1013(G/A polymorphism in combination with IGF-2R +1619(G/A polymorphism is an independent prognostic factor in advanced

    Cetuximab, in combination with platinum chemotherapy plus 5-fluoruracil (5-FU), is approved for the first-line treatment of recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN). Cetuximab manufactured by ImClone (US commercial cetuximab) potentially results in higher systemic exposures than cetuximab manufactured by Boehringer Ingelheim (BI-manufactured cetuximab). This prospective, randomized, double-blind study compared the safety profiles of the two cetuximab formulations. Patients with previously untreated locoregionally recurrent and/or metastatic SCCHN were randomly assigned to receive the same dose of US commercial cetuximab (Arm A) or BI-manufactured cetuximab (Arm B), each in combination with cisplatin or carboplatin plus 5-FU. The primary outcome was all-grade, all-cause treatment-emergent adverse events (TEAEs). The majority of patients experienced ≥ 1 TEAE, regardless of causality (Arm A: 75/77 patients, 97.4%; Arm B: 68/71 patients, 95.8%). TEAEs with the highest incidence included nausea, fatigue, and hypomagnesemia in both arms. The absolute risk difference between the two arms for patients experiencing at least one adverse event (AE) was 0.029 (p = 0.281, 95% confidence interval [CI]: -0.024, 0.082) for AEs regardless of causality and 0.005 (p = 0.915, 95% CI: -0.092, 0.103) for AEs possibly related to study drug. There were no significant differences between the two arms in the incidence of acneiform rash, cardiac events, infusion reactions, or hypomagnesemia. Overall survival, progression-free survival, and overall response rates were similar in the two arms. There were no clinically meaningful differences in safety between US commercial cetuximab and BI-manufactured cetuximab in combination with platinum-based therapy with 5-FU in patients with locoregionally recurrent and/or metastatic SCCHN. The use of US commercial cetuximab in this combination chemotherapy regimen did not result in any unexpected safety signals. The

    The paper is to systematically evaluate the effect and safety of Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy for non-small cell lung cancer (NSCLC). Randomized controlled trials (RCTs) on Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy (experiment group) and chemotherapy alone group ( control group) were electronically retrieved from Medline, EMbase, Clinical Trials, Cochrane Library, CBM, CNKI, VIP, and Wanfang Data base. All trials were assessed for quality according to the Cochrane Reviewer's Handbook for Systematic Reviews of Intervention and then Meta-analysis was performed withRevMan5. 2 Software. A total of 43 RCTs (3433 patients) were included after screening and selecting. Results of Meta-analysis showed that: Objective remission rate (ORR): ORR of experimental group was about 20% higher than that of control group [RR = 1.23, 95% CI (1.11,1.35), P < 0.0001]. Disease control rate (DCR):DCR of SFI combined with first-line chemotherapy was 11% higher than that of first-line chemotherapy alone [RR = 1.11, 95% CI (1.07, 1.16), P < 0.000 01]. Life quality evaluated by Kosovan performance status (KPS) showed that: life quality improvement rate of experimental group was about twice of that in control group [RR = 2.02, 95% CI (1.81, 2.26), P < 0.000 01]. Toxic and side reaction analysis showed that: the incidence of side reactions in experimental group was about 50% lower than that in control group [RR = 0.59, 95% CI (0.53, 0.66), P < 0.000 01]. Immune function test showed that: the function of experimental group was 3.2 (standard deviations) times greater than that of control group [MD = 3.23, 95% CI (2.86, 3.60), P < 0.000 01]. We can see that SFI combined with first-line chemotherapy for NSCLC can increase objective efficacy, improve life quality, decrease toxic and side reactionsinduced by chemotherapy, and improve the immune functions. As most of the included studies in this systematic evaluation had poor quality

    According to current guidelines, endocrine therapy (ET) is recommended as first-line treatment of luminal-like metastatic breast cancer (MBC), whereas chemotherapy (CT) should be considered in presence of life-threatening disease. In daily practice, CT is often used outside of this clinical circumstance. Factors influencing first-line choice and the relative impact on outcome are unknown. A consecutive series of luminal-like HER2-negative MBC patients treated from 2004 to 2014 was analyzed to test the association of disease- and patient-related factors with the choice of first-line treatment (ET vs. CT). A propensity score method was used to estimate impact of first-line strategy on outcome. Of 604 consecutive luminal-like MBC patients identified, 158 cases were excluded due to unknown or positive HER2-status. Among 446 HER2-negative cases, 171 (38%) received first-line CT. On multivariate analysis, the only factors significantly associated with lower CT use were old age (OR 0.25, 95%C.I. 0.13-0.49) or presence of bone metastases only (OR 0.26, 95%C.I. 0.13-0.53). In propensity score matched population, no differences were observed between CT and ET as first-line treatment either in terms of overall survival (37.5 months and 33.4 months respectively, log-rank test, P = 0.62) or progression-free survival (13.3 months and 9.9 months respectively, log-rank test, P = 0.92). High percentage of patients with luminal-like MBC received CT as first-line therapy in real-life. The choice was mainly driven by age and site of metastases. With the limitations of a non-randomized comparison, no differences on patients' outcome were observed depending on the first-line strategy. Copyright © 2016 The Authors. Published by Elsevier Ltd..

    ABSTRACT Patients with acute leukemia are susceptible to chemotherapy-induced severe myelosuppression, and therefore are at a high risk for febrile neutropenia (FN). In such cases, the use of broad-spectrum antibiotics such as fourth-generation cephalosporins and carbapenems is recommended as first-line antimicrobial treatment; however, the effectiveness of these agents in patients with acute myeloid leukemia (AML) has not been investigated in detail. We retrospectively examined and evaluated the effectiveness of first-line antibiotic treatment regimens for chemotherapy-induced FN in patients with AML in Japanese Red Cross Nagoya Daiichi Hospital. The evaluated first-line treatment regimens were as follows: cefozopran (CZOP) + amikacin (AMK) in 38 cases, cefepime (CFPM) alone in 2 cases, CFPM + AMK in 2 cases, piperacillin (PIPC) + AMK in 2 cases, and CZOP alone in 1 case. Additionally, prophylactic antifungal agents were administered in all cases. Markedly effective, effective, moderately effective, and ineffective responses occurred in 31.1%, 8.9%, 8.9%, and 51.1%, respectively, of the treated cases. The response rate, defined as the combination of markedly effective and effective outcomes, was 40.0%. In 11 cases, impairment of renal functions were observed, and they were associated with combination treatments including AMK; nine of these were associated with a glycopeptide. The combination of CZOP with AMK (84.4%) was the most commonly used first-line treatment for FN in patients with AML; carbapenem or tazobactam/PIPC has never been used for treatment of such cases. Our findings demonstrate that fourth-generation cephems will be an effective first-line treatment for FN in patients with AML in our hospital. PMID:28303057

    The JNK and P38α pathways play a crucial role in tissue homeostasis, apoptosis and autophagy under genotoxic stresses, but it is unclear whether single nucleotide polymorphisms (SNPs) of genes in these pathways play a role in platinum-based chemotherapy-induced toxicities in patients with advanced non-small cell lung cancer (NSCLC). We genotyped 11 selected, independent, potentially functional SNPs of nine genes in the JNK and P38α pathways in 689 patients with advanced NSCLC treated with platinum-combination chemotherapy regimens. Associations between these SNPs and chemotherapy toxicities were tested in a discovery group of 345 patients and then validated in a replication group of 344 patients. In both discovery and validation groups as well as their pooled analysis, carriers of GADD45B rs2024144T variant allele had a significantly higher risk for severe hematologic toxicity and carriers of MAPK14 rs3804451A variant allele had a significantly higher risk for both overall toxicity and gastrointestinal toxicity. In addition, carriers of GADD45A rs581000C had a lower risk of anemia, while carriers of GADD45B rs2024144T had a significantly higher risk for leukocytopenia or agranulocytosis. The present study provides evidence that genetic variants in genes involved in the JNK and P38α pathways may predict platinum-based chemotherapy toxicity outcomes in patients with advanced NSCLC. Larger studies of other patient populations are needed to validate our findings. PMID:26993769

    Survival times of women starting first-line chemotherapy for metastatic breast cancer (MBC) in routine clinical practice were determined and compared with those from a systematic review of randomised clinical trials. We identified women with MBC starting first-line chemotherapy from June 2003 to February 2011 and recorded their demographics, tumour and treatment characteristics, and survival times from the start of chemotherapy. Their survival distribution was summarised by the following percentiles (represented scenarios for survival): 90th (worst-case), 75th (lower-typical), 25th (upper-typical) and 10th (best-case), which were compared with the same percentiles from our systematic review of first-line chemotherapy trials. The 273 women had a median age of 56 years, and a median time from diagnosis of MBC of 3 months. Eastern Cooperative Oncology Group performance status was 0-1 in 80%. Tumours were hormone receptor positive in 69%, human epidermal growth factor receptor 2 (HER2)-positive in 27% and triple negative in 13%. Survival times in months in routine clinical practice (vs the systematic review) were: 90th percentile 4 (6); 75th percentile 9 (12); median 20 (22); 25th percentile 36 (36) and 10th percentile 61 (56). Independent predictors of overall survival included HER2-positive disease (hazard ratio (HR) 0.49, P = 0.0002), hormone receptor positive disease (HR 0.51, P = 0.0004), Eastern Cooperative Oncology Group performance status 0-1 (HR 0.36, P HR 1.86, P = 0.0002). Median and better survival times in routine practice were similar to those from randomised clinical trials; however, survival times worse than the median were shorter, likely reflecting patient selection in trials. Oncologists should adjust trial-based survival estimates for patients not meeting typical trial eligibility criteria. © 2013 The Authors; Internal Medicine Journal © 2013 Royal Australasian College of Physicians.

    Objectives To determine the recommended dose and efficacy/safety of docetaxel combined with resminostat (DR) in non-small cell lung cancer (NSCLC) patients with previous platinum-based chemotherapy. Materials and Methods A multicenter, open-label, phase I/II study was performed in Japanese patients with stage IIIB/IV or recurrent NSCLC and prior platinum-based chemotherapy. The recommended phase II dose was determined using a standard 3 + 3 dose design in phase I part. Resminostat was escalated from 400 to 600 mg/day and docetaxel fixed at 75 mg/m(2). In phase II part, the patients were randomly assigned to docetaxel alone (75 mg/m(2)) or DR therapy. Docetaxel was administered on day 1 and resminostat on days 1-5 in the DR group. Treatment was repeated every 21 days until progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). Results A total of 117 patients (phase I part, 9; phase II part, 108) were enrolled. There was no dose-limiting toxicity in phase I part; the recommended dose for resminostat was 600 mg/day with 75 mg/m(2) of docetaxel. In phase II part, median PFS (95% confidence interval [CI]) was 4.2 (2.8-5.7) months with docetaxel group and 4.1 (1.5-5.4) months with DR group (hazard ratio [HR]: 1.354, 95% CI: 0.835-2.195; p = 0.209). Grade ≥ 3 adverse events significantly more common with DR group than docetaxel group were leukopenia, febrile neutropenia, thrombocytopenia, and anorexia. Conclusion In Japanese NSCLC patients previously treated with platinum-based chemotherapy, DR therapy did not improve PFS compared with docetaxel alone and increased toxicity.

    Full Text Available This study was designed to assess the role of first-line chemotherapy with 5-FU and platinum in the treatment of advanced or recurrent cervical cancer, ten patients with advanced or recurrent cancer of the cervix, with no prior chemotherapy were entered in phase II trial, from Oct. 2000 to Nov. 2001. Eight patients were treated with cis-platinum (50 mg/m2 over 60 minutes in first day followed by 5-FU (1 g/m2 over 24 hours for 4 days and two patients with impaired renal function were treated with carboplatin (300 mg/m2 over 15 minutes in first day followed by 5-FU (1 g/m2 over 24 hours for 4 days every three weeks, until progression of disease or prohibitive toxicity had been observed. Median age was 52 years (range: 28-70 years. Ten patients received a total of 42 cycles of chemotherapy. The mean number of chemotherapy cycles was 4.2 (median 4, range: 3-7. Three patients had partial response (30%, CI, 1.7%-58.5%. Mean response duration was 198 days (range: 122-273 days. Four patients required red blood cell transfusions; three of them had grade II and one of them grade III nausea and vomiting Two had fever and neutropenia (one developed acute renal insufficiency, and there wee no treatment related mortalities. First-line chemotherapy with platinum and 5-FU for advanced recurrent cervical cancer is promising and deserves consideration for large phase III trials.

    Cachexia and sarcopenia are associated with poor outcome and increased chemotherapy-induced toxicity in lung cancer patients. However, the complex interplay of obesity, sarcopenia and cachexia, and its impact on survival in the context of first-line-chemotherapy is not yet understood. In 200 consecutively recruited lung cancer patients (70 female, mean age 62y; mean BMI 25 kg/m2; median follow-up 15.97 months) with routine staging-CT before and after chemotherapy (CTX, mean interval: 4.3 months), densitometric quantification of total (TFA), visceral (VFA), and subcutaneous-fat-area (SFA), inter-muscular-fat-area (IMFA), muscle-density (MD), muscle-area (MA) and skeletal-muscle-index (SMI) was performed retrospectively to evaluate changes under chemotherapy and the impact on survival. We observed increases in TFA, VFA, SFA, VFA/SFA, and IMFA (pdecreases in MA, MD and BMI (pDecrease in BMI (HR = 1.303; pincreased survival (17.6 vs. 9.1months), less muscle depletion (SMIdifference: pdecreased muscle and increased adipose tissue compartments, which was not adequately mirrored by BMI and weight loss but by imaging. Particularly sarcopenic patients received less CTX-cycles and had poorer survival. As loss of BMI, weight and muscle were associated with poor survival, early detection (via imaging) and prevention (via physical exercise and nutrition) of sarcopenia may potentially improve outcome and reduce chemotherapy-induced toxicity.

    TAS-102 is an oral combination treatment comprised of an antimetabolite, trifluridine, a thymidine-based nucleoside analog, and tipiracil hydrochloride, at a molar ratio of 1:0.5. This antimetabolite has demonstrated efficacy in clinical trials, including a global phase 3 trial in metastatic colorectal cancer. As this agent has shown activity greater than cisplatin in small cell lung cancer xenograft mouse models, the objective of this study was to evaluate TAS-102 in the second-line treatment of small cell lung cancer. This was a multicenter, open-label, two-arm, randomized phase 2 study designed to compare oral TAS-102 (35mg/m(2)/dose twice daily) versus control (topotecan or amrubicin). Patients requiring second-line chemotherapy for treatment of small cell lung cancer, either refractory or sensitive to frontline platinum-based chemotherapy, were enrolled. Eighteen patients were enrolled. Eight of nine patients receiving TAS-102 discontinued treatment due to progressive disease and one patient died due to clinical progression during the safety follow-up. Unplanned interim futility considerations were made, and the study was terminated early because it was unlikely that superiority of TAS-102 versus comparator could be demonstrated. Six control patients discontinued therapy due to progressive disease and one due to an adverse event. Median progression-free survival was 1.4 months (range 0.9-1.8) versus 2.7 months (range 1.0-6.8) for TAS-102 and control, respectively, with a hazard ratio of 3.76 (80% CI, 1.68-8.40) favoring control. The most common adverse events with TAS-102 were neutropenia, diarrhea, anemia, anorexia, and fatigue, each in three patients. TAS-102 showed no evidence of activity in second-line small cell lung cancer. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    This trial evaluated the efficacy of maintenance erlotinib, an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, after first-line chemotherapy. Eligible patients had high-risk International Federation of Gynecology and Obstetrics stage I or stage II to IV epithelial ovarian, primary peritoneal, or fallopian tube cancer and were not selected for EGFR expression. All patients underwent first-line platinum-based chemotherapy (CT) and showed no signs of progression at the end of CT. Patients were randomly assigned to maintenance erlotinib 150 mg orally daily for 2 years or to observation. EGFR immunohistochemistry (IHC), fluorescent in situ hybridization (FISH), and mutation analyses were performed in 318 patients. Between October 2005 and February 2008, 835 patients were randomly assigned (median follow-up, 51 months). Twenty-six percent of the patients stopped erlotinib as a result of adverse effects (of these, 67% were due to rash). For erlotinib and observation, respectively, the median progression-free survival was 12.7 and 12.4 months (hazard ratio [HR], 1.05; 95% CI, 0.90 to 1.23), and the median overall survival was 50.8 and 59.1 months (HR, 0.99; 95% CI, 0.81 to 1.20 months), respectively. No subgroup could be identified with improved effect of erlotinib, based on IHC or FISH for EGFR, or mutations in genes related to the EGFR pathway, or on rash during erlotinib therapy. However, patients with a positive FISH EGFR score had a worse overall survival (46.1 months) than those with a negative score (67.0 months; HR, 1.56; 95% CI, 1.01 to 2.40; P = .044). Global health/quality-of-life scores showed a significant difference during the first year (P = .0102) in favor of the observation arm. Maintenance erlotinib after first-line treatment in ovarian cancer did not improve progression-free or overall survival.

Results We observed increases in TFA, VFA, SFA, VFA/SFA, and IMFA (p<0.05–0.001), while there were decreases in MA, MD and BMI (p<0.05–0.001) after chemotherapy. High pre-therapeutic VFA/SFA was a predictive factor for poor survival (HR = 1.272; p = 0.008), high pre-therapeutic MD for improved survival (HR = 0.93; p<0.05). Decrease in BMI (HR = 1.303; p<0.001), weight (HR = 1.067; p<0.001) and SMI (HR = 1.063; p<0.001) after chemotherapy were associated with poor survival. Patients with ≥4 CTX-cycles showed increased survival (17.6 vs. 9.1months), less muscle depletion (SMIdifference: p<0.05) and no BMI loss (BMIdifference: p<0.001). Conclusions After chemotherapy, patients exhibited sarcopenia with decreased muscle and increased adipose tissue compartments, which was not adequately mirrored by BMI and weight loss but by imaging. Particularly sarcopenic patients received less CTX-cycles and had poorer survival. As loss of BMI, weight and muscle were associated with poor survival, early detection (via imaging) and prevention (via physical exercise and nutrition) of sarcopenia may potentially improve outcome and reduce chemotherapy-induced toxicity.

    Full Text Available The combination of chemotherapy and epidermal growth factor receptor (EGFR tyrosine kinase inhibitors (TKIs currently has become the hotspot issue in the treatment of non-small lung cancer (NSCLC. This systematic review was conducted to compare the efficacy and safety of the synchronous combination of these two treatments with EGFR TKIs or chemotherapy alone in advanced NSCLC.EMBASE, PubMed, the Central Registry of Controlled Trials in the Cochrane Library (CENTRAL, Chinese biomedical literature database (CNKI and meeting summaries were searched. The Phase II/III randomized controlled trials were selected by which patients with advanced NSCLC were randomized to receive a combination of EGFR TKIs and chemotherapy by synchronous mode vs. EGFR TKIs or chemotherapy alone.A total of six randomized controlled trials (RCTs including 4675 patients were enrolled in the systematic review. The meta-analysis demonstrated that the synchronous combination group of chemotherapy and EGFR TKIs did not reach satisfactory results; there was no significant difference in overall survival (OS, time to progression (TTP and objective response rate (ORR, compared with monotherapy (OS: HR = 1.05, 95%CI = 0.98-1.12; TTP: HR = 0.94, 95%CI = 0.89-1.00; ORR: RR = 1.07, 95%CI = 0.98-1.17, and no significant difference in OS and progression-free survival (PFS, compared with EGFR TKIs alone (OS: HR = 1.10, 95% CI = 0.83-1.46; PFS: HR = 0.86, 95% CI = 0.67-1.10.

    Full Text Available BACKGROUND: The use of cetuximab in combination with platinum (P plus 5-fluorouracil (F has previously been demonstrated to be effective in the treatment of metastatic squamous cell cancer of head and neck (SCCHN. We investigated the efficacy and outcome of this protocol as a first-line treatment for patients with recurrent or metastatic disease. We evaluated overall-survival (OS, progression-free-survival (PFS, overall response rate (ORR and the treatment toxicity profile in a retrospective cohort. PATIENTS AND METHODS: This study enrolled 121 patients with untreated recurrent or metastatic SCCHN. The patients received PF+ cetuximab every 3 weeks for a maximum of 6 cycles. Patients with stable disease who received PF+ cetuximab continued to receive cetuximab until disease progressed or unacceptable toxic effects were experienced, whichever occurred first. RESULTS: The median patient age was 53 (37-78 years. The patient cohort was 86.8% male. The addition of cetuximab to PF in the recurrent or metastatic setting provided an OS of 11 months (Confidential Interval, CI, 95%, 8.684-13.316 and PFS of 8 months (CI 95%, 6.051-9.949. The disease control rate was 48.9%, and the ORR was 23.91%. The most common grade 3 or 4 adverse events in the PF+ cetuximab regimen were febrile neutropenia (5.7%, skin rash (3.8% and mucosistis (3.8%. CONCLUSIONS: The results of this study suggest that cetuximab plus platinum-fluorouracil chemotherapy is a good option for systemic treatment in advanced SSCHN patients. This regimen has a well-tolerated toxicity profile.

    IMPORTANCE Combining biologic monoclonal antibodies with chemotherapeutic cytotoxic drugs provides clinical benefit to patients with advanced or metastatic colorectal cancer, but the optimal choice of the initial biologic therapy in previously untreated patients is unknown. OBJECTIVE To determine if the addition of cetuximab vsbevacizumab to the combination of leucovorin, fluorouracil, and oxaliplatin (mFOLFOX6) regimen or the combination of leucovorin, fluorouracil, and irinotecan (FOLFIRI) regimen is superior as first-line therapy in advanced or metastatic KRAS wild-type (wt) colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS Patients (≥18 years) enrolled at community and academic centers throughout the National Clinical Trials Network in the United States and Canada (November 2005-March 2012) with previously untreated advanced or metastatic colorectal cancer whose tumors were KRAS wt chose to take either the mFOLFOX6 regimen or the FOLFIRI regimen as chemotherapy and were randomized to receive either cetuximab (n = 578) or bevacizumab (n = 559). The last date of follow-up was December 15, 2015. INTERVENTIONS Cetuximab vs bevacizumab combined with either mFOLFOX6 or FOLFIRI chemotherapy regimen chosen by the treating physician and patient. MAIN OUTCOMES AND MEASURES The primary end point was overall survival. Secondary objectives included progression-free survival and overall response rate, site-reported confirmed or unconfirmed complete or partial response. RESULTS Among 1137 patients (median age, 59 years; 440 [39%] women), 1074 (94%) of patients met eligibility criteria. As of December 15, 2015, median follow-up for 263 surviving patients was 47.4 months (range, 0–110.7 months), and 82% of patients (938 of 1137) experienced disease progression. The median overall survival was 30.0 months in the cetuximab-chemotherapy group and 29.0 months in the bevacizumab-chemotherapy group with a stratified hazard ratio (HR) of 0.88 (95% CI, 0.77–1.01; P = .08).

    Glioblastoma multiforme (GBM), the most frequent brain tumor in adults, is not considered chemosensitive. Nevertheless, there is widespread use of first-line chemotherapy, often with temozolomide, as a therapeutic option in patients with progressive disease after surgery and radiotherapy. However, at the time of second recurrence and/or progression, active and noncross-resistant chemotherapy regimens are required. The aim of the present multicenter phase II trial, therefore, was to ascertain the efficacy of second-line carmustine (BCNU) and irinotecan chemotherapy. Patients with histologically confirmed GBM, recurring or progressing after surgery, standard radiotherapy and a first-line temozolomide-based chemotherapy, were considered eligible. The primary end-point was progression-free survival at 6 months (PFS-6), and secondary end-points included response rate, toxicity, and survival. All patients were on enzyme-inducing antiepileptic prophylaxis. Chemotherapy consisted of BCNU (100 mg/m2 on day 1) plus irinotecan (175 mg/m2/weekly for 4 weeks), every 6 weeks, for a maximum of eight cycles. In the absence of grade 2 toxicity, the irinotecan dose was increased to 200 mg/m2. A total of 42 patients (median age, 53.4 years; median Karnofsky performance status, 80; range, 60 to 90) were included in the study. PFS-6 was 30.3% (95% CI, 18.5% to 49.7%). Median time to progression was 17 weeks (95% CI, 11.9 to 23.9). Nine partial responses (21.4%; 95% CI, 9% to 34%) were obtained. Toxicity was manageable. The BCNU plus irinotecan regimen seems active and non-cross-resistant in patients with GBM with recurrence after temozolomide-based chemotherapy.

    First-line chemotherapy regimens suitable for elderly advanced breast cancer patients are still not defined. Women with stage III or IV breast cancer aged > or =70 years were enrolled in a phase II study aimed to evaluate both activity and toxicity of weekly paclitaxel. Among 46 planned patients, at least 18 responses and not more than seven unacceptable toxic events are required for a favourable conclusion. Paclitaxel 80 mg/m(2) was administered weekly for 3 weeks every 28 days. Unacceptable toxicity occurred in seven out of 46 patients evaluated for toxicity [15.2%; exact 95% confidence interval (CI) 7.6% to 28.2%] and was represented by one case of febrile neutropenia, one case of severe allergic reaction and five cases of cardiac toxicity. Among 41 patients evaluated for response, a complete response occurred in two (4.9%) patients and a partial response in 20 (48.8%), with an overall response rate of 53.7% (exact 95% CI 38.7% to 67.9%). The median progression-free survival was 9.7 months (95% CI 8.5-18.7) and median survival was 35.8 months (95% CI 19-not defined). Weekly paclitaxel is highly active in elderly advanced breast cancer patients. Data on cardiovascular complications, however, indicate the need for a careful monitoring of cardiac function before and during chemotherapy.

    Full Text Available Decision-making capacity to provide informed consent regarding treatment is essential among cancer patients. The purpose of this study was to identify the frequency of decision-making incapacity among newly diagnosed older patients with hematological malignancy receiving first-line chemotherapy, to examine factors associated with incapacity and assess physicians' perceptions of patients' decision-making incapacity.Consecutive patients aged 65 years or over with a primary diagnosis of malignant lymphoma or multiple myeloma were recruited. Decision-making capacity was assessed using the Structured Interview for Competency and Incompetency Assessment Testing and Ranking Inventory-Revised (SICIATRI-R. Cognitive impairment, depressive condition and other possible associated factors were also evaluated.Among 139 eligible patients registered for this study, 114 completed the survey. Of these, 28 (25%, 95% confidence interval [CI]: 17%-32% were judged as having some extent of decision-making incompetency according to SICIATRI-R. Higher levels of cognitive impairment and increasing age were significantly associated with decision-making incapacity. Physicians experienced difficulty performing competency assessment (Cohen's kappa -0.54.Decision-making incapacity was found to be a common and under-recognized problem in older patients with cancer. Age and assessment of cognitive impairment may provide the opportunity to find patients that are at a high risk of showing decision-making incapacity.

    This note presents a comparison of the use of saliva versus leukocytes for the determination of Pt-DNA adducts obtained from patients undergoing platinum-based chemotherapy. Samples of both blood and saliva were taken pre- and post-treatment and were analysed via sector-field inductively coupled plasma mass spectrometry (SF-ICP-MS) to determine the level of Pt-DNA adducts formed. As expected, significant inter-patient variability was seen; however, a lack of correlation between the levels of adducts observed in saliva and blood samples was also observed (Pearson correlation coefficient r = -0.2598). A high yield of DNA was obtained from saliva samples, but significant difficulties were experienced in obtaining patient adherence to the saliva sampling procedure. In both leukocyte and saliva samples, not only was Pt from previous chemotherapy cycles detected, but the rapid appearance of Pt in the DNA was noted in both sample types 1 h after treatment.

    Background: The therapeutic paradigm of metastatic urothelial carcinoma (UC) is rapidly shifting and new biomarkers are needed to enhance patient selection. Objective: Early identification of dynamic predictors of outcome may be a key to optimize the sequence of effective therapies in metastatic UC patients. Methods: Blood samples from patients receiving first-line MVAC chemotherapy were collected at baseline (T0) and after 2 cycles (T2). Samples were processed by immunomagnetic beads (AdnaTest ProstateCancerSelect kit) and the expression of EPCAM, MUC1 and ERBB2 was studied using multiplex-PCR. Circulating tumor cell (CTC) positivity and cutoffs, obtained by receiver operator characteristic (ROC) curve analysis in healthy donors, were: ≥1 positive marker among EPCAM (≥0.40 ng/μl), MUC1 (≥0.10 ng/μl) and ERBB2 (≥0.20 ng/μl). CTC variation (T0/T2) was split in favorable (+/–, –/–, –/+) and unfavorable groups (+/+). Cox regression analyses evaluated associations with clinical factors. Results: In this pilot study to assess a new CTC detection method, among 31 evaluable patients, 17 (54.8%) were CTC-positive at T0. No association was found between CTC and objective response to MVAC. CTC dynamic changes better predicted 3-year progression-free (PFS) and overall survival (OS) compared to CTC status assessed at single time points. Unfavorable trend was univariably detrimental on 3-year PFS (10% vs. 49.2%, p = 0.006) and OS (20% vs. 63.5%, p = 0.017). Significance was maintained after controlling for liver metastases (p = 0.031 and p = 0.025 for PFS and OS) and MSKCC score (p = 0.014 and 0.025). Conclusions: Newly described early CTC changes during chemotherapy might be useful to improve our prognostic ability. Pending validation, these results could fulfill the promise to help accelerating therapeutic sequences. PMID:28035320

    Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) mediates apoptosis via binding to death receptors and enhances the anti-tumor effect of conventional cancer therapies. We evaluated the efficacy of TRA-8, an agonistic antibody to DR5, combined with docetaxel and carboplatin in vitro in an intraperitoneal (IP) ovarian cancer model. Luciferase positive ES2 cells (ES2H) were treated in 96 well plates with TRA-8, carboplatin, docetaxel, and combination therapy. Cell viability was assessed using ATP-lite assay. Apoptosis was confirmed via Western blot analysis. ES2H cells were injected IP into female athymic nude mice. Animals were sorted based on bioluminescent signal with the following treatments: 1) untreated; 2) TRA-8 alone; 3) docetaxel+carboplatin; and 4) docetaxel+carboplatin+TRA-8. Animals receiving TRA-8 antibody were injected IP with 200 μg of TRA-8 twice weekly until death. Animals receiving docetaxel+carboplatin were injected IP with 5mg/kg and 15 mg/kg respectively every 3 weeks until death. Animals were assessed for tumor burden using bioluminescence imaging and overall survival. Combination therapy reduced viability of ES2H cells in vitro over single agent therapy. Tumor burden was lowest in the chemotherapy+TRA-8 group at days 23 (pTRA-8 group (41 days) compared to the chemotherapy only group (34 days) and control group (27 days) as determined by Kaplan-Meier analysis (pTRA-8 reduced cell-viability via activation of apoptotic pathways, reduced tumor burden and improved survival in this ovarian cancer model.

    Data suggest selective internal radiotherapy (SIRT) in third-line or subsequent therapy for metastatic colorectal cancer has clinical benefit in patients with colorectal liver metastases with liver-dominant disease after chemotherapy. The FOXFIRE, SIRFLOX, and FOXFIRE-Global randomised studies evaluated the efficacy of combining first-line chemotherapy with SIRT using yttrium-90 resin microspheres in patients with metastatic colorectal cancer with liver metastases. The studies were designed for combined analysis of overall survival. FOXFIRE, SIRFLOX, and FOXFIRE-Global were randomised, phase 3 trials done in hospitals and specialist liver centres in 14 countries worldwide (Australia, Belgium, France, Germany, Israel, Italy, New Zealand, Portugal, South Korea, Singapore, Spain, Taiwan, the UK, and the USA). Chemotherapy-naive patients with metastatic colorectal cancer (WHO performance status 0 or 1) with liver metastases not suitable for curative resection or ablation were randomly assigned (1:1) to either oxaliplatin-based chemotherapy (FOLFOX: leucovorin, fluorouracil, and oxaliplatin) or FOLFOX plus single treatment SIRT concurrent with cycle 1 or 2 of chemotherapy. In FOXFIRE, FOLFOX chemotherapy was OxMdG (oxaliplatin modified de Gramont chemotherapy; 85 mg/m(2) oxaliplatin infusion over 2 h, L-leucovorin 175 mg or D,L-leucovorin 350 mg infusion over 2 h, and 400 mg/m(2) bolus fluorouracil followed by a 2400 mg/m(2) continuous fluorouracil infusion over 46 h). In SIRFLOX and FOXFIRE-Global, FOLFOX chemotherapy was modified FOLFOX6 (85 mg/m(2) oxaliplatin infusion over 2 h, 200 mg leucovorin, and 400 mg/m(2) bolus fluorouracil followed by a 2400 mg/m(2) continuous fluorouracil infusion over 46 h). Randomisation was done by central minimisation with four factors: presence of extrahepatic metastases, tumour involvement of the liver, planned use of a biological agent, and investigational centre. Participants and investigators were not masked to treatment. The

    Full Text Available OBJECTIVE: Platinum-based doublet chemotherapy is considered the standard of care for advanced non-small cell lung cancer (NSCLC. However, prognosis after recurrent or progressive disease following first-line chemotherapy is usually poor. Maintenance chemotherapy, second line treatment and even third line chemotherapy are available for patients with advanced NSCLC. Unfortunately, few patients are candidates for chemotherapy beyond first line. The present study evaluated characteristics of patients with NSCLC and outcomes of the treatment of their metastatic disease, with emphasis on second and third-line chemotherapy. METHODS: This was a retrospective observational study of 2,673 patients with metastatic, stage IV, non-small cell lung cancer admitted for treatment in two São Paulo institutions. First-line chemotherapy was defined as the first chemotherapeutic approach administered to the patient. Second and third-line chemotherapy were defined as the systemic treatment administered after discontinuing first-line chemotherapy, either for intolerance or for progressive or recurrent disease. RESULTS: Most patients (57.9% received first-line chemotherapy, and approximately 23.4% received second-line and 8% third-line regimens. Only 2.5% received fourth-line chemotherapy.

    The purpose of this study was to evaluate the efficacy of 3 first-line chemotherapy combination regimens for HER2-negative metastatic breast cancer (mBC). In this open-label, 3-arm, randomized phase II trial, patients were randomized to all-oral NORCAP (vinorelbine/capecitabine), GEMPAC (gemcitabine/paclitaxel), or GEMDOC (gemcitabine/docetaxel) as first-line chemotherapy for HER2-negative mBC. Stratification factors were center, previous (neo)adjuvant anthracycline, and age. The primary end point was disease control rate (DCR; complete or partial response, or stable disease for ≥3 months). The DCR was 73% (95% confidence interval [CI], 59-85) with NORCAP (36 of 49 patients), 78% (95% CI, 64-88) with GEMPAC (39 of 50 patients), and 80% (95% CI, 66-90) with GEMDOC (40 of 50 patients). Objective response rates were 33% (16 of 49 patients), 24% (12 of 50 patients), and 50% (25 of 50 patients), respectively; median progression-free survival was 7.6, 9.0, and 11.4 months, respectively. Median overall survival was 30 to 31 months with all regimens. The most common Grade ≥3 adverse event with each regimen was neutropenia (24 patients [50%], 23 patients [46%], and 43 patients [86%], respectively). The most common nonhematological Grade ≥3 adverse event was fatigue. Grade 2 alopecia occurred in 36 patients (72%) who received GEMPAC and 38 patients (76%) who received GEMDOC, but only 4 patients (8%) who received NORCAP. There was no evidence of a detrimental effect of NORCAP on quality of life. All-oral NORCAP is an active first-line chemotherapy regimen and might be offered as an alternative to first-line taxane-based therapy for HER2-negative mBC, particularly if patients wish to avoid alopecia or frequent intravenous administrations.

    Cisplatin and temozolomide (TMZ) are active in glioblastoma multiforme (GBM), with different profiles of toxicity. A bid regimen of TMZ achieves a strong inhibition of O(6)-alkylguanine DNA-alkyl transferase (AGAT), and cisplatin reduces AGAT activity in vitro, suggesting a possible synergic interaction. The primary end point of the present multicenter phase II study was progression-free survival (PFS) at 6 months (PFS-6); secondary end points included response, toxicity, and overall survival. Chemotherapy-naive patients with GBM who experienced disease recurrence or progression after surgery and standard radiotherapy were eligible. Chemotherapy cycles consisted of cisplatin 75 mg/m(2) on day 1, TMZ 130 mg/m(2) bolus followed by nine doses of 70 mg/m(2) every 12 hours (total of 5 days) from day 2 every 4 weeks. In the absence of hematologic toxicity, TMZ was escalated to 1,000 mg/m(2) in 5 days. A total of 50 patients (median age, 53.4 years; range, 27 to 70 years; median Karnofsky performance status, 80; range, 60 to 100) were accrued in the study. PFS-6 was 34% (95% CI, 23% to 50%), and PFS-12 was 4% (95% CI, 0.3% to 16%). Median PFS was 18.4 weeks (95% CI, 13 to 25.9 weeks). Among 49 assessable patients, one complete response and nine partial responses were obtained, with an overall response rate of 20.4% (95% CI, 7.7% to 33%). Among 203 treatment cycles delivered, the most common grade 3 or grade 4 events included granulocytopenia in 7.9% of cycles, thrombocytopenia in 4%, and neurologic toxicity in three patients (6%). The new cisplatin plus bid TMZ regimen appears active in chemotherapy-naive patients with recurrent GBM and incurs an acceptable toxicity.

    Several predictors of metastatic colorectal cancer (mCRC) outcomes have been described. Specific geriatric characteristics could be of interest to determine prognosis. Elderly patients (75+) with previously untreated mCRC were randomly assigned to receive infusional 5-fluorouracil-based chemotherapy, either alone (FU) or in combination with irinotecan (IRI). Geriatric evaluations were included as an optional procedure. The predictive value of geriatric parameters was determined for the objective response rate (ORR), progression-free survival (PFS) and overall survival (OS). From June 2003 to May 2010, the FFCD 2001-02 randomised trial enrolled 282 patients. A baseline geriatric evaluation was done in 123 patients; 62 allocated to the FU arm and 61 to the IRI arm. The baseline Charlson index was ≤1 in 75%, Mini-Mental State Examination was ≤27/30 in 31%, Geriatric Depression Scale was >2 in 10% and Instrumental Activities of Daily Living (IADL) was impaired in 34% of the patients. Multivariate analyses revealed that no geriatric parameter was predictive for ORR or PFS. Normal IADL was independently associated with better OS. The benefit of doublet chemotherapy on PFS differed in subgroups of patients ≤80 years, with unresected primary tumour, leucocytes >11,000 mm(3) and carcinoembryonic antigen >2N. There was a trend towards better OS in patients with normal IADL. The autonomy score was an independent predictor for OS. A trend toward a better efficacy of doublet chemotherapy in some subgroups of patients was reported and should be further explored. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This study was designed to evaluate the feasibility, toxicity, and efficacy of rituximab added to the VNCOP-B (etoposide/mitoxantrone/cyclophosphamide/vincristine/prednisone/bleomycin) combination regimen for the treatment of elderly patients with large B-cell lymphoma. Previously untreated patients > or = 65 years of age with stage II, III, or IV large B-cell non-Hodgkin's lymphoma were treated with a modified VNCOP-B regimen with weekly chemotherapy for 8 weeks. In addition, patients received rituximab 375 mg/m2 intravenously on weeks 1, 2, 3, 4, 6, and 8. All patients received prophylactic granulocyte colony-stimulating factor (G-CSF) or granulocyte-macrophage colony-stimulating factor (GM-CSF) during the 8 weeks of treatment. Between August 1999 and February 2002, 41 patients entered this multicenter phase II trial. The median age was 74 years, and 54% of patients had high-risk tumors (age-adjusted International Prognostic Index scores of 2 or 3). Sixty-eight percent of patients completed the 8 weeks of therapy. Overall response rate was 66%; actuarial progression-free survival rate at 2 years was 59%, with a 57% actuarial overall 2-year survival rate. Patients > or = 75 years of age had similar treatment outcomes compared with younger patients. Toxicity with this regimen was predominantly related to chemotherapy; rituximab was well tolerated. Grade 3/4 neutropenia occurred in 83% of patients even with routine use of prophylactic G-CSF or GM-CSF. Treatment-related death occurred in 4 patients (10%). VNCOP-B plus rituximab is efficacious, producing 2-year progression-free survival rates that compare favorably with those of other active regimens in this patient group. Hematologic toxicity was increased compared with previous reports with VNCOP-B alone, as evidenced by the treatment-related mortality rate of 10% in the present study. Differences in toxicity may have been caused by the addition of rituximab, the modified etoposide schedule, or the differences in

    Purpose To establish whether maintenance lapatinib after first-line chemotherapy is beneficial in human epidermal growth factor receptor (HER) 1/HER2-positive metastatic urothelial bladder cancer (UBC). Methods Patients with metastatic UBC were screened centrally for HER1/HER2 overexpression. Patients who screened positive for HER1/2 and who did not have progressive disease during chemotherapy (four to eight cycles) were randomly assigned one to one to lapatinib or placebo after completion of first-line/initial chemotherapy for metastatic disease. The primary end point was progression-free survival (PFS). Results Between 2007 and 2013, 446 patients with UBC were screened, and 232 with HER1- or HER2-positive disease were randomly assigned. The median PFS for lapatinib and placebo was 4.5 (95% CI, 2.8 to 5.4) and 5.1 (95% CI, 3.0 to 5.8) months, respectively (hazard ratio, 1.07; 95% CI, 0.81 to 1.43; P = .63). The overall survival for lapatinib and placebo was 12.6 (95% CI, 9.0 to 16.2) and 12.0 (95% CI, 10.5 to 14.9) months, respectively (hazard ratio, 0.96; 95% CI, 0.70 to 1.31; P = .80). Discontinuation due to adverse events were similar in both arms (6% lapatinib and 5% placebo). The rate of grade 3 to 4 adverse events for lapatinib and placebo was 8.6% versus 8.1% ( P = .82). Preplanned subset analysis of patients strongly positive for HER1/HER2 (3+ on immunohistochemistry; n = 111), patients positive for only HER1 (n = 102), and patients positive for only HER2 (n = 42) showed no significant benefit with lapatinib in terms of PFS and overall survival ( P > .05 for each). Conclusion This trial did not find significant improvements in outcome by the addition of maintenance lapatinib to standard of care.

    Enumeration of circulating tumor cells (CTCs) is a promising tool in the management of metastatic breast cancer (MBC). This study investigated the capturing efficiency and prognostic value of our previously reported peptide-based nanomagnetic CTC isolation system (Pep@MNPs). We counted CTCs in blood samples taken at baseline (n = 102) and later at patients' first clinical evaluation after starting firstline chemotherapy (n = 72) in a cohort of women treated for MBC. Their median follow-up was 16.3 months (range: 9.0-31.0 months). The CTC detection rate was 69.6 % for the baseline samples. Patients with ≤2 CTC/2 ml at baseline had longer median progression-free survival (PFS) than did those with >2 CTC/2 ml (17.0 months vs. 8.0 months; P = 0.002). Patients with ≤2 CTC/2 ml both at baseline and first clinical evaluation had longest PFS (18.2 months) among all patient groups (P = 0.004). Particularly, among patients with stable disease (SD; per imaging evaluation) our assay could identify those with longer PFS (P 2 CTC/2 ml at baseline were also significantly more likely to suffer liver metastasis (P = 0.010). This study confirmed the prognostic value of Pep@MNPs assays for MBC patients who undergo firstline chemotherapy, and offered extra stratification regarding PFS for patients with SD, and a possible indicator for patients at risk for liver metastasis.

    Full Text Available Abstract Background Elderly patients have been often excluded from or underrepresented in the study populations of combination chemotherapy trials. The primary end point of this study was to determine the response rate and the toxicity of the weekly oxaliplatin, 5-fluorouracil and folinic acid (OXALF regimen in elderly patients with advanced gastric cancer. The secondary objective was to measure the time to disease progression and the survival time. Methods Chemotherapy-naive patients with advanced gastric cancer aged 70 or older were considered eligible for study entry. Patients received weekly oxaliplatin 40 mg/m2, fluorouracil 500 mg/m2 and folinic acid 250 mg/m2. All drugs were given intravenously on a day-1 schedule. Results A total of 42 elderly patients were enrolled. Median age was 73 years and all patients had metastatic disease. The response rate according to RECIST criteria was 45.2% (95% CIs: 30%–56% with two complete responses, 17 partial responses, 13 stable diseases and 10 progressions, for an overall tumor rate control of 76.2% (32 patients. Toxicity was generally mild and only three patients discontinued treatment because of treatment related adverse events. The most common treatment-related grade 3/4 adverse events were fatigue (7.1%, diarrhoea (4.8%, mucositis (2.4%, neurotoxicity (2.4% and neutropenia (4.8%. The median response duration was 5.3 months (95% CIs: 2.13 – 7.34, the median time to disease progression was 5.0 months (95% CIs: 3.75 – 6.25 and the median survival time was 9.0 months (95% CIs: 6.18 – 11.82. Conclusion OXALF represents an active and well-tolerated treatment modality for elderly patients with locally advanced and metastatic gastric cancer.

    In the MACRO study, patients with metastatic colorectal cancer (mCRC) were randomised to first-line treatment with 6 cycles of capecitabine and oxaliplatin (XELOX) plus bevacizumab followed by either single-agent bevacizumab or XELOX plus bevacizumab until disease progression. An additional retrospective analysis was performed to define the prognostic value of tumour KRAS status on progression-free survival (PFS), overall survival (OS) and response rates. KRAS data (tumour KRAS status and type of mutation) were collected by questionnaire from participating centres that performed KRAS analyses. These data were then cross-referenced with efficacy data for relevant patients in the MACRO study database. KRAS status was analysed in 394 of the 480 patients (82.1%) in the MACRO study. Wild-type (WT) KRAS tumours were found in 219 patients (56%) and mutant (MT) KRAS in 175 patients (44%). Median PFS was 10.9 months for patients with WT KRAS and 9.4 months for patients with MT KRAS tumours (p=0.0038; HR: 1.40; 95% CI:1.12-1.77). The difference in OS was also significant: 26.7 months versus 18.0 months for WT versus MT KRAS, respectively (p=0.0002; HR: 1.55; 95% CI: 1.23-1.96). Univariate and multivariate analyses showed that KRAS was an independent variable for both PFS and OS. Responses were observed in 126 patients (57.5%) with WT KRAS tumours and 76 patients (43.4%) with MT KRAS tumours (p=0.0054; OR: 1.77; 95% CI: 1.18-2.64). This analysis of the MACRO study suggests a prognostic role for tumour KRAS status in patients with mCRC treated with XELOX plus bevacizumab. For both PFS and OS, KRAS status was an independent factor in univariate and multivariate analyses.

    The aim of this study was to prospectively evaluate the value of [{sup 11}C] Choline PET/CT in monitoring early and late response to a standardized first-line docetaxel chemotherapy in castration refractory prostate cancer (mCRPC) patients. Thirty-two patients were referred for [{sup 11}C] Choline PET/CT before the start of docetaxel chemotherapy, after one and ten chemotherapy cycles (or - in case of discontinuation - after the last administered cycle) for therapy response assessment. [{sup 11}C] Choline uptake (SUV{sub max}, SUV{sub mean}), CT derived Houndsfield units (HU{sub max}, HU{sub mean}), and volume of bone, lung, and nodal metastases and local recurrence were measured semi-automatically at these timepoints. Change in SUV{sub max}, SUV{sub mean}, HU{sub max}, HU{sub mean,} and volume was assessed between PET 2 and 1 (early response assessment, ERA) and PET 3 and 1 (late response assessment, LRA) on a patient and lesion basis. Results of PET/CT were compared to clinically used RECIST 1.1 and clinical criteria based therapy response assessment including PSA for defining progressive disease (PD) and non-progressive disease (nPD), respectively. Relationships between changes of SUV{sub max} and SUV{sub mean} (early and late) and changes of PSA{sub early} and PSA{sub late} were evaluated. Prognostic value of initial SUV{sub max} and SUV{sub mean} was assessed. Statistical analyses were performed using SPSS. In the patient-based ERA and LRA there were no statistically significant differences in change of choline uptake, HU, and volume between PD and nPD applying RECIST or clinical response criteria. In the lesion-based ERA, decrease in choline uptake of bone metastases was even higher in PD (applying RECIST criteria), whereas in LRA the decrease was higher in nPD (applying clinical criteria). There were only significant correlations between change in choline uptake and PSA in ERA in PD, in LRA no significant correlations were discovered. Initial SUV{sub max

    Despite the lack of evidence to support its implementation in the clinical practice, induction chemotherapy (IC) before chemoradiotherapy (CRT) is often used in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN). We retrospectively examined the tolerability, feasibility, and clinical outcome of both concepts in a single center analysis. In all, 83 patients were treated between 2007 and 2010 with IC + CRT (n = 42) or CRT alone (n = 41). IC consisted of docetaxel, cisplatin and 5-fluorouracil (TPF), or cisplatin and 5-fluorouracil (PF). All patients were scheduled to receive 2 cycles of PF during concurrent CRT. Adverse events were assessed according to the common toxicity criteria of adverse events (CTCAE v. 3.0). Associations were tested using the χ{sup 2} test, and survival estimates were calculated according to Kaplan-Meier. The median follow-up was 30.35 months (range 2.66-61.25 months). At 2 years, the overall survival rate was significantly higher for primary CRT compared to IC + CRT group (74.8 % vs. 54 %, respectively; p = 0.041). Significantly more treatment-related overall grade 4 toxicities were documented in the IC + CRT group compared to the CRT group (42.9% vs. 9.8%; p = 0.001). Renal toxicity ≥ grade 2 occurred in 52.4 % vs. 7.3 % (p < 0.001), respectively. In all, 93 % of the patients with primary CRT compared to 71 % with IC + CRT received the planned full radiotherapy dose (p = 0.012). This is, to our knowledge, the largest retrospective study to compare IC + CRT with primary CRT. IC showed high acute toxicity, compromised the feasibility of concurrent CRT, and was associated with reduced overall survival rates compared to primary CRT. The lack of clinical benefit in conjunction with the increased toxicity does not support implementation of IC. (orig.)

    Cellular resistance in advanced gastric cancer (GC) might be related to function of multidrug resistance (MDR) proteins. The adaptor protein NHERF1 (Na+/H+ exchanger regulatory factor) is an important player in cancer progression for a number of solid malignancies, even if its role to develop drug resistance remains uncertain. Herein, we aimed to analyze the potential association between NHERF1 expression and P-gp, sorcin and HIF-1α MDR-related proteins in advanced GC patients treated with epirubicin/oxaliplatin/capecitabine (EOX) chemotherapy regimen, and its relation to response. Total number of 28 untreated patients were included into the study. Expression and subcellular localization of all proteins were assessed by immunohistochemistry on formalin-fixed paraffin embedded tumor samples. We did not found significant association between NHERF1 expression and the MDR-related proteins. A trend was observed between positive cytoplasmic NHERF1 (cNHERF1) expression and negative nuclear HIF-1α (nHIF-1α) expression (68.8% versus 31.3% respectively, P = 0.054). However, cytoplasmic P-gp (cP-gp) expression was positively correlated with both cHIF-1α and sorcin expression (P = 0.011; P = 0.002, respectively). Interestingly, nuclear NHERF1 (nNHERF1) staining was statistically associated with clinical response. In detail, 66.7% of patients with high nNHERF1 expression had a disease control rate, while 84.6% of subjects with negative nuclear expression of the protein showed progressive disease (P = 0.009). Multivariate analysis confirmed a significant correlation between nNHERF1 and clinical response (OR 0.06, P = 0.019). These results suggest that nuclear NHERF1 could be related to resistance to the EOX regimen in advanced GC patients, identifying this marker as a possible independent predictive factor.

    In colorectal cancer (CRC), unresectable liver metastases are associated with a poor prognosis. The FOXFIRE (an open-label randomized phase III trial of 5-fluorouracil, oxaliplatin, and folinic acid +/- interventional radioembolization as first-line treatment for patients with unresectable liver-only or liver-predominant metastatic colorectal cancer), SIRFLOX (randomized comparative study of FOLFOX6m plus SIR-Spheres microspheres versus FOLFOX6m alone as first-line treatment in patients with nonresectable liver metastases from primary colorectal carcinoma), and FOXFIRE-Global (assessment of overall survival of FOLFOX6m plus SIR-Spheres microspheres versus FOLFOX6m alone as first-line treatment in patients with nonresectable liver metastases from primary colorectal carcinoma in a randomized clinical study) clinical trials were designed to evaluate the efficacy and safety of combining first-line chemotherapy with selective internal radiation therapy (SIRT) using yttrium-90 resin microspheres, also called transarterial radioembolization. The aim of this analysis is to prospectively combine clinical data from 3 trials to allow adequate power to evaluate the impact of chemotherapy with SIRT on overall survival. Eligible patients are adults with histologically confirmed CRC and unequivocal evidence of liver metastases which are not treatable by surgical resection or local ablation with curative intent at the time of study entry. Patients may also have limited extrahepatic metastases. Final analysis will take place when all participants have been followed up for a minimum of 2 years. Efficacy and safety estimates derived using individual participant data (IPD) from SIRFLOX, FOXFIRE, and FOXFIRE-Global will be pooled using 2-stage prospective meta-analysis. Secondary outcome measures include progression-free survival (PFS), liver-specific PFS, health-related quality of life, response rate, resection rate, and adverse event profile.

    Cetuximab improves efficacy when added to chemotherapy for metastatic colorectal cancer (mCRC). Effective management of skin reactions from cetuximab improves quality of life (QoL), and treatment compliance in clinical trials. No data are available from real-world settings. The ObservEr observational, multicenter, prospective study evaluated QoL, the incidence of skin reactions, and management of chemotherapy plus cetuximab in first-line for mCRC. The primary endpoint was QoL measured with the Dermatology Life Quality Index (DLQI) and EORTC QLQ-C30. Secondary endpoints were the incidence of skin and serious adverse events, median overall and progression-free survival, tumor response, and resection rates. Between May 2011 and November 2012, 228 patients with KRASwt mCRC were enrolled at 28 Italian centers, 225 evaluable, median age 65 years. QoL did not change during treatment and was not affected by the choice of prophylactic or reactive skin management. The incidence of cetuximab-specific grade ≥3 skin reactions was 14%, with no grade 4/5 events. Skin reactions correlated with survival (P = 0.016), and their incidence was influenced by chemotherapy regimen (oxaliplatin vs. irinotecan-Incidence rate ratio [IRR] 1.72, P < 0.0001) and gender (male vs. female-IRR 1.38, P = 0.0008). Compliance at first postbaseline evaluation was 97.75%. Median overall survival was 23.6 months, median progression-free survival 8.3 months. Cetuximab plus chemotherapy did not compromise QoL in the routine clinical setting when patients receive close monitoring plus prophylactic or reactive management of skin reactions. We observed the same correlation between overall survival (OS) and skin reactions reported in controlled clinical trials, also in this setting.

    Objective To investigate whether SNPs of ERCCKC118T) and XPD(Lys751Gln) were associated with the sensitivity of non-small-cell lung cancer ( NSCLC) to platinum-based chemotherapy in the patients with advanced NSCLC. Methods Polymorphisms of ERCC1 and XPD were detected by PCR-restrictive fragment length polymorphism (PCR-RFLP) method in 78 cases. Results No association was detected between polymorphisms of ERCC1 and XPD and age, sex, histologic type,ECOG performance status,smoking history and clinical stage of tumor.

    We compared continuous versus stop-and-go chemotherapy after disease stabilisation with induction chemotherapy in the first-line treatment of metastatic gastric cancer (MGC). MGC patients who achieved disease control after 6 cycles of S-1/oxaliplatin (SOX) were randomised to receive either continuous SOX until progression (continuous arm) or to have a chemotherapy-free interval followed by SOX reintroduction at progression (stop-and-go arm). The primary end-point was overall survival (OS). Of the 250 patients enrolled, 247 participated in the induction phase. Of these, 121 patients were randomised to the continuous arm (n = 59) or the stop-and-go arm (n = 62). Progression-free survival (PFS) was significantly longer in the continuous arm than in the stop-and-go arm (10.5 versus 7.2 months; hazard ratio [HR] 0.55, 95% CI, 0.37-0.81; P = 0.002). Duration of disease control (DDC) and OS, however, were comparable between the two arms: median DDC, 10.5 versus 11.3 months, HR 0.92 (95% CI, 0.62-1.36; P = 0.674); median OS, 22.6 versus 22.7 months, HR 0.78 (95% CI, 0.50-1.23; P = 0.284). Adverse events including grade ≥3 fatigue (28.8% versus 8.1%; P = 0.003) and sensory neuropathy (25.4% versus 9.7%; P = 0.022) occurred more frequently in the continuous arm than in the stop-and-go arm. Quality of life (QOL) including global health status, physical/role functioning and other symptom scores significantly favoured the stop-and-go arm. Compared with the stop-and-go strategy, maintenance chemotherapy improved PFS but not DDC and OS and had a negative impact on QOL, suggesting the stop-and-go strategy may be an appropriate option in MGC patients following induction chemotherapy.

    Full Text Available Preclinical and clinical studies have suggested that expression of ribonucleotide reductase regulatory subunit M1 (RRM1 and excision repair cross-complementation group 1 (ERCC1 is associated with resistance to gemcitabine and cisplatin, respectively. We evaluated the significance of RRM1 and ERCC1 expression to predict tumor response to gemcitabine plus platinum chemotherapy (GP and survival in advanced UC. We retrospectively collected tumor samples and reviewed clinical data of 53 patients with unresectable or metastatic UC, who were treated with first-line GP. RRM1 and ERCC1 expression were measured by immunohistochemistry. Among 53 patients, 12 (22.6% and 26 (49.1% patients had tumors that demonstrated a high expression for RRM1 and ERCC1, respectively. Twenty-nine (70.7% of 41 patients with low RRM1 expression achieved a clinical response (complete + partial responses, but only 3 (25.0% of 12 patients with high RRM1 expression achieved a clinical response after GP (P=0.007. Nineteen (70.4% of 27 patients with low ERCC1 expression achieved a clinical response, while 13 (50.0% of 26 patients with high ERCC1 expression achieved a clinical response (P=0.130. High RRM1 expression was associated with shorter progression free survival and overall survival (PFS P=0.006, OS P=0.006. Multivariate analysis confirmed that patients with high RRM1 expression had a significantly greater risk of progression and death than those with low RRM1 expression. ERCC1 status was not a significant predictor for PFS and OS. RRM1 expression was predictive and prognostic of clinical outcome in advanced UC treated with gemcitabine plus platinum combination chemotherapy.

    Hand-foot syndrome (HFS) is a limiting toxicity of capecitabine, which is not life-threatening but could compromise capecitabine efficacy. This phase II, multicenter, non-controlled study assessed the safety, particularly grade three HFS incidence, and efficacy of four capecitabine-based chemotherapy regimens [cisplatin/capecitabine (CX), epirubicin/cisplatin/capecitabine (ECX), epirubicin/oxaliplatin/capecitabine (EOX) and docetaxel/cisplatin/capecitabine (DCX)] as first-line treatment for advanced and/or metastatic gastric cancer. One hundred and eight patients were assigned to one of the four treatment groups, according to investigator's criteria, and grouped together for both safety and efficacy primary analyses. HFS was reported in 31 patients (19.6%) and its first presentation occurred at a median of 72 days (range 19-209 days). Grade 3 HFS developed in 6.3, 5.2, 3.7 and 2.4%, of patients receiving ECX, DCX, EOX or CX chemotherapy regimen, respectively. Capecitabine dose reduction/discontinuation due to HFS was required in 5.7% of patients (9/158). The most common (> 10%) grade 3-4 treatment-related AEs were neutropenia (15.2%), asthenia (12.0%) and diarrhoea (11.4%). A moderate incidence of HFS was reported in patients treated with capecitabine, which generally presented late and required dose reduction in < 1/3 of patients. The results suggest that capecitabine may be useful in combination with standard fluorouracil-based regimens in patients with advanced and/or metastatic gastric cancer with favourable safety profile.

    Background There is no standard first-line chemotherapy for advanced urothelial carcinoma (aUC) in cisplatin-ineligible (cisplatin-unfit) patients. The study assessed the efficacy and tolerability profile of two vinflunine-based cytotoxic regimens in this setting. Patients and methods Patients with aUC a creatinine clearance (CrCl) of <60 but ≥30 ml/min, performance status 0 or 1 and no prior chemotherapy for advanced disease were randomized (1 : 1). They received vinflunine 250 or 280 mg/m2 (based on baseline CrCl) on day 1, plus either gemcitabine [750 mg/m2 escalated to 1000 mg/m2 in cycle 2 if no toxicity grade (G) ≥2 on days 1 and 8 (VG) or plus carboplatin area under the curve 4.5 day 1 (VC) every 21 days]. To detect a 22% improvement in each arm compared with H0 (41%) in the primary end point, disease control rate (DCR = complete response + partial response + stable disease), 31 assessable patients per arm were required (α = 5%, β = 20%). Results Sixty-nine patients were enrolled (34 VG, 35 VC). Less G3/4 haematological adverse events (AEs) were reported with VG: neutropaenia was seen in 38% (versus 68% with VC) and febrile neutropaenia in 3% (versus 14% with VC) of patients. No major differences were observed for non-haematological AEs. DCR was 77% in both groups; overall response rate (ORR) was 44.1% versus 28.6%, with a median progression-free survival of 5.9 versus 6.1 months and median OS of 14.0 versus 12.8 months with VG and VC, respectively. Conclusion Both vinflunine-based doublets offer a similar DCR, ORR and OS. The better haematological tolerance favours the VG combination, which warrants further study.

    We have planned a multicentre prospective study to examine the relative impact of the efficacy and adverse events of cetuximab plus first-line chemotherapy on the quality of life in Japanese patients with KRAS wild-type unresectable colorectal cancer. The Dermatology Life Quality Index and the European Organization for Research Treatment of Cancer Quality of Life Questionnaire Core 30 will be used to assess dermatology-specific and health-related quality of life. The severity of adverse events will be assessed by using the National Cancer Institute Common Terminology Criteria for adverse Events ver. 4.0. The endpoints will be the following associations: adverse events, including skin toxicity and quality of life; efficacy and skin toxicity; efficacy and quality of life; and skin-related quality of life and health-related quality of life. A total of 140 patients are considered to be appropriate for inclusion in this study. The results of this study will provide more information to both patients and physicians regarding the practical use of cetuximab and its impact on quality of life in patients with unresectable colorectal cancer in Japan. This study was registered at the University Hospital Medical Information Network Clinical Trial Registry as UMIN000010985.

    Abstract Background: Trials investigating the efficacy and safety of combining molecular targeted agent (MTA) with platinum–gemcitabine (PG) in first-line treatment of advanced non-small cell lung cancer (NSCLC) have shown inconsistent findings. This meta-analysis aimed to explore whether the addition of MTAs to PG in NSCLC could provide a survival benefit with a tolerable toxicity. Methods: Web of knowledge, PubMed, Ovid, Embase, and Cochrane Library were searched to identify relevant studies and extract data on overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and common grade 3 or 4 adverse events. Subgroup analyses were conducted on the basis of race and the type of MTA. Results: Twelve trials with a total of 6143 patients were included in this meta-analysis. Compared with PG chemotherapy, combination therapy of MTA with PG did not improve OS (hazard ratio [HR] = 0.96, 95% confidence interval [CI] = 0.90–1.01) but improved PFS (HR = 0.77, 95% CI = 0.66–0.89) and ORR (risk ratio [RR] = 1.33, 95% CI = 1.11–1.60). Subanalysis indicated that there was more incidence of grade 3 or 4 rash (RR = 11.20, 95% CI = 6.07–20.68), anemia (RR = 1.21, 95% CI = 1.01–1.46), diarrhea (RR = 2.62, 95% CI = 1.21–5.65), and anorexia (RR = 2.08, 95% CI = 1.12–3.88) in combining epidermal growth factor receptor targeted therapy group compared to PG group. An increased risk of grade 3 or 4 rash (RR = 5.08, 95% CI = 1.53–16.79), thrombocytopenia (RR = 1.50, 95% CI = 1.03–2.18), and hypertension (RR = 2.36, 95% CI = 1.05–5.32) was observed in sorafenib combination group. Conclusion: The combination of PG plus MTA was superior to PG alone in terms of PFS and ORR but not in OS. The combination chemotherapy also showed a higher frequency of grade 3 or higher toxic effects in patients with advanced NSCLC than PG chemotherapy. PMID:27977596

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available Recent advances in understanding the mechanisms of nonsmall cell lung cancer (NSCLC has led to the development of targeted treatments, including the reversible epidermal growth factor receptor (EGFR tyrosine kinase inhibitors gefitinib and erlotinib, and the irreversible ErbB family blocker afatinib. Several important activating EGFR mutations have now been identified, which correlate strongly with response to treatment with these agents. Multiple randomised controlled trials have confirmed the association between the presence of activating EGFR mutations and objective response to gefitinib, erlotinib and afatinib, thus demonstrating their superiority over platinum-based chemotherapy as first-line treatment for NSCLC patients with EGFR mutation-positive tumours, and resulting in approval of these agents for use in this setting. It can be tempting to compare outcome data across multiple clinical trials and agents; however, substantial differences in methodology between studies, including investigator versus independent assessment and differences in patient eligibility, makes such comparisons fraught with difficulty. This critical review provides an overview of the evolution of the methodology used in eight phase III trials investigating first-line targeted treatment of NSCLC, identifies key differences in methodology and reporting, and critically assesses how these differences should be taken into account when interpreting the findings from such trials.

    The purpose of this study was to propose a time-series modeling and simulation (M&S) strategy for probabilistic cost-effective analysis in cancer chemotherapy using a Monte-Carlo method based on data available from the literature. The simulation included the cost for chemotherapy, for pharmaceutical care for adverse events (AEs) and other medical costs. As an application example, we describe the analysis for the comparison of four regimens, cisplatin plus irinotecan, carboplatin plus paclitaxel, cisplatin plus gemcitabine (GP), and cisplatin plus vinorelbine, for advanced non-small cell lung cancer. The factors, drug efficacy explained by overall survival or time to treatment failure, frequency and severity of AEs, utility value of AEs to determine QOL, the drugs' and other medical costs in Japan, were included in the model. The simulation was performed and quality adjusted life years (QALY) and incremental cost-effectiveness ratios (ICER) were calculated. An index, percentage of superiority (%SUP) which is the rate of the increased cost vs. QALY-gained plots within the area of positive QALY-gained and also below some threshold values of the ICER, was calculated as functions of threshold values of the ICER. An M&S process was developed, and for the simulation example, the GP regimen was the most cost-effective, in case of threshold values of the ICER=$70000/year, the %SUP for the GP are more than 50%. We developed an M&S process for probabilistic cost-effective analysis, this method would be useful for decision-making in choosing a cancer chemotherapy regimen in terms of pharmacoeconomic.

    The staging of node-negative non-small-cell lung cancer is modified in the 7th edition TNM classification. Here, we pool data from the National Cancer Institute of Canada Clinical Trials Group JBR.10 trial and the Cancer and Leukemia Group B-9633 trial to explore the prognostic and predictive effects of the new T-size descriptors and KRAS mutation status. Node-negative patients were reclassified as T2a (>3-≤5 cm), T2b (>5-≤7 cm), T3 (>7 cm) or T ≤ 3 cm (≤3 cm, but other T2 characteristics). Of 538 eligible patients, 288 (53.5%) were T2a, 111 (21%) T2b, 62 (11.5%) T3, whereas 77 (14%) T≤3 cm were excluded to avoid confounding. KRAS mutations were detected in 104 of 390 patients (27%). T-size was prognostic for disease-free survival (p = 0.03), but borderline for overall survival (OS; p = 0.10), on multivariable analysis. Significant interaction between the prognostic value of KRAS and tumor size was observed for OS (p = 0.01), but not disease-free survival (p = 0.10). There was a nonsignificant trend (p = 0.24) for increased chemotherapy effect on OS with advancing T-size (hazard ratio [HR] T2a 0.90, [0.63-1.30]; T2b 0.69, [0.38-1.24]; and T3 0.57, [0.28-1.17]). The HR for chemotherapy effect on OS in T2a patients with KRAS wild-type tumors was 0.81 (p = 0.36), whereas a trend for detrimental effect was observed in those with mutant tumors (HR 2.11; p = 0.09; interaction p = 0.05). Similar trends were observed in T2b to T3 patients with wild-type (HR 0.86; p = 0.62), and KRAS mutant tumors (HR 1.16; p = 0.74; interaction p = 0.58). Chemotherapy effect seems to increase with tumor size. However, this small study could not identify subgroups of patients who did or did not derive significant benefit from adjuvant chemotherapy based on T-size or KRAS status.

    Patients with non-small cell lung cancer (NSCLC) with mutated epidermal growth factor receptor (EGFR) are relatively sensitive to EGFR-tyrosine kinase inhibitor (TKI) treatment and have longer progression-free survival (PFS) when treated with EGFR-TKI compared with platinum-based chemotherapy. However, many patients with advanced NSCLC who have mutated EGFR do not respond to first-line EGFR-TKI treatment and still have shorter PFS. The aim of this study was to identify genetic variants associated with PFS among patients with lung adenocarcinoma who were treated with first-line EGFR-TKIs. A genome-wide association study on PFS was performed in never-smoking women diagnosed with lung adenocarcinoma and who were treated with first-line EGFR-TKIs (n = 128). Significant single-nucleotide polymorphisms (SNPs) were selected for follow-up association analysis (n = 198) and for replication assay in another independent cohort (n = 153). We identified SNPs at 4q12 associated with PFS at genome-wide significance (P Genetic variants in 4q12 merit further investigation to assess their potential as pharmacogenomic predictors for and to understand the biology underlying its influence on PFS in patients treated with TKI therapy.

    Patients with advanced non-small-cell lung cancer (NSCLC) have poor survival, and platinum-based chemotherapy agents are the standard first-line chemotherapy agents for advanced NSCLC. This study aimed to identify predictive factors associated with the response to chemotherapy and survival in 258 patients with advanced NSCLC treated with platinum-based chemotherapy. Stage IIIA-IV NSCLC patients diagnosed in Kaifeng second people's hospital (Henan, China) between March 2002 and September 2011 were retrospectively reviewed. All of the patients had received platinum-based chemotherapy, and patients were followed up to date of death or last follow-up to obtain data of response to chemotherapy and survival. Potential prognostic factors such as gender, age, tumor size, tumor type, histologic stage, anemia, calcium levels, ECOG performance status (PS), thrombocytosis, TTF-1, p63, and connexin 43 were analyzed. Response to chemotherapy, overall survival (OS) and progression-free survival (PFS) were calculated by the Kaplan-Meier method and Cox regression model. A univariate analysis indicated that thrombocytosis and connexin 43 were found to be significant prognostic factors (p thrombocytosis was associated with increased mortality and resistance to chemotherapy in chemotherapy responders. In addition, all 21 patients of the 5-year OS were from chemotherapy responders with connexin 43 ≥ +2 or non-thrombocytosis. Thrombocytosis and connexin 43 absence may be reliable surrogate markers for the prediction of chemotherapy response and prognosis for patients with advanced NSCLC, and assessment of these factors may identify a population of patients with advanced NSCLC that is likely to have a prolonged life expectancy.

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

    WHO standard of care for failure of a first regimen, usually 2N(t)RTI's and an NNRTI, consists of a ritonavir-boosted protease inhibitor with a change in N(t)RTI's. Until recently, there was no evidence to support these recommendations which were based on expert opinion. Two large randomized clinical trials, SECOND LINE and EARNEST both showed excellent response rates (>80%) for the WHO standard of care and indicated that a novel regimen of a boosted protease inhibitor with an integrase inhibitor had equal efficacy with no difference in toxicity. In EARNEST, a third arm consisting of induction with the combined protease and integrase inhibitor followed by protease inhibitor monotherapy maintenance was inferior and led to substantial (20%) protease inhibitor resistance. These studies confirm the validity of the current recommendations of WHO and point to a novel public health approach of using two new classes for second line when standard first-line therapy has failed, which avoids resistance genotyping. Notwithstanding, adherence must be stressed in those failing first-line treatments. Protease inhibitor monotherapy is not suitable for a public health approach in low- and middle-income countries.

    The development of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) changed dramatically the history of non-small cell lung cancer (NSCLC) harboring EGFR sensitive mutations. Several randomized prospective trials confirmed the superiority of these target agents about survival and response rate when comparing with platinum-based chemotherapy. Knowledge about EGFR mutations increased gradually during the development of target agents and different clinical trials. EGFR mutations cannot be considered all equal, but different entities should be considered in our clinical practice: exon 19 deletions, exon 21 mutation (L858R) and uncommon mutation (exon 20, exon 18 and double mutation). Nowadays, we dispose of three different EGFR TKIs (afatinib, erlotinib and gefitinib) approved for the treatment for first-line treatment of patients di NSCLC carrying EGFR, that was compared only by indirect analysis, producing data not always clear and convincing. This research highlight is an overview of data about EGFR TKIs in first-line setting, focusing on differences about exon 19 deletions and L585R mutation in patients treated with different TKIs. In addition, we report the preliminary results of the first head-to-head randomized clinical trial between two different EGFR TKIs, the LUX-Lung 7 (LL7) that compared afatinib and gefitinib showing interesting results.

    In the HD15 trial of the German Hodgkin Study Group, the negative predictive value (NPV) of positron emission tomography (PET) using [18F]-fluorodeoxyglucose in advanced-stage Hodgkin lymphoma (HL) was evaluated. A total of 817 patients were enrolled and randomly assigned to receive BEACOPP-based chemotherapy. After completion of chemotherapy, residual disease measuring more than or equal to 2.5 cm in diameter was assessed by PET in 311 patients. The NPV of PET was defined as the proportion of PET− patients without progression, relapse, or irradiation within 12 months after PET review panel. The progression-free survival was 96% for PET− patients (95% confidence interval [CI], 94%-99%) and 86% for PET+ patients (95% CI, 78%-95%, P = .011). The NPV for PET in this analysis was 94% (95% CI, 91%-97%). Thus, consolidation radiotherapy can be omitted in PET− patients with residual disease without increasing the risk for progression or early relapse compared with patients in complete remission. The impact of this finding on the overall survival at 5 years must be awaited. Until then, response adapted therapy guided by PET for HL patients seems to be a promising approach that should be further evaluated in clinical trials. This trial is registered at http://isrctn.org study as #ISRCTN32443041. PMID:18757777

    Platinum-based drugs (cisplatin, carboplatin, and oxaliplatin) are widely used therapeutic agents for cancer treatment. Even though the platinum (Pt)-drugs are routinely used clinically, a clear picture of their distribution within tumor tissues is lacking. The current methods to image the distribution of Pt drugs are limited and do not enable the discrimination of the drug from its metabolites. In this manuscript, we demonstrate a methodology that enables chemical imaging of a Pt drug and its metabolites simultaneously and specifically. Matrix-Assisted Laser Desorption/Ionization (MALDI) Mass Spectrometry Imaging (MSI) is combined with an on-tissue chemical derivatization using diethyldithiocarbamate (DDTC). DDTC abstracts the Pt atom to generate ionizable complexes that can be imaged by MALDI MSI. We demonstrate that Pt drugs and their metabolites can be specifically imaged. This approach was successfully applied to map the penetration and metabolism of oxaliplatin in hyperthermic intraperitoneal chemotherapy (HIPEC)-like treated 3D colorectal tumor mimics. The distribution of cisplatin and carboplatin was mapped in additional 3D tumor mimics. We demonstrate that the approach can also be used to image the distribution of copper ions in cells. This method has the potential to be used to evaluate the penetration and distribution of a wide range of compounds.

    As part of its Single Technology Appraisal process, the National Institute for Health and Care Excellence (NICE) invited the manufacturer of olaparib (AstraZeneca) to submit evidence on the clinical and cost effectiveness of olaparib for the maintenance treatment of BRCA1/2 mutated (BRCAm), platinum-sensitive relapsed (PSR) ovarian, fallopian tube and peritoneal cancer in people whose relapsed disease has responded to platinum-based chemotherapy. The Evidence Review Group (ERG) produced a critical review of the evidence contained within the company's submission (CS) to NICE. The clinical evidence related to one phase II, double-blind randomised controlled trial that recruited 265 patients with PSR serous ovarian cancer (OC) regardless of BRCAm status. Patients received olaparib 400 mg twice daily (b.i.d.) or matched placebo. In the whole population, the primary endpoint of progression-free survival (PFS) was met (hazard ratio [HR] 0.35; 95 % confidence interval [CI] 0.25-0.49, p group (HR 0.88; 95 % CI 0.64-1.21; p = 0.44) or the BRCAm subgroup (0.73; 95 % CI 0.45-1.17; p = 0.19), though treatment switching may have confounded results. The exclusion of data from sites allowing crossover resulted in an HR for overall survival (OS) of 0.52 (95 % CI 0.28-0.97, p = 0.039) in the BRCAm group. Health-related quality-of-life measures were not significantly different between groups. All post hoc exploratory outcomes (time to treatment discontinuation/death, time to first subsequent therapy/death, and time to second subsequent therapy/death) were statistically significantly better in the olaparib arm in the whole population and the BRCAm subgroup analyses. Adverse events were more frequent for olaparib but were largely minor or manageable. The company's semi-Markov model assessed the cost effectiveness of olaparib versus routine surveillance in patients with BRCAm PSR OC from a National Health Service (NHS) and Personal Social Services (PSS) perspective over a

    Cervical cancer is the fourth most common cancer affecting women worldwide. Despite advances in screening and human papillomavirus (HPV) vaccination, a significant number of women present with or develop advanced disease. Palliative platinum-based chemotherapy (CT) is the standard first-line treatment for metastatic/recurrent cervical cancer. The prognosis remains poor and effective second line options are urgently needed. We searched the English-language medical literature as well as relevant guideline databases, published from January 1981 to December 2015 and identified publications related to cervical cancer and its therapies. Our effort was to highlight the available treatment options in the setting of recurrent/metastatic disease. Although there have been important advances in the management of women with cervical cancer, the optimal treatment for patients with locally recurrent and metastatic disease after platinum failure is still problematic. Overall, there is a trend in terms of longer overall survival (OS) and better quality of life for the combination of cisplatin/paclitaxel (PC) as compared to the doublets of cisplatin/topotecan (TC), cisplatin/vinorelbine (VC), and cisplatin/gemcitabine (GC). Currently available single agents beyond first-line platinum-based therapy have limited efficacy in this setting and include topoisomerase inhibitors, vinca alkaloids, taxanes, alkylating agents and antimetabolites. Several targeted therapies have demonstrated activity in advanced cervical cancer. Bevacizumab has been evaluated in a phase III trial using doublets of cisplatin with paclitaxel or topotecan and has been approved in the first-line setting by the U. S. Food and Drug Administration. Selective targeting of angiogenic kinases by tyrosine kinase inhibitors (TKIs) may represent a novel therapeutic tool in this setting, but its use alone or in combination with CT is still investigational. Early reports have implicated PI3KCA somatic mutations suggesting

    Objective: Based on published literatures, the study aimed to compare the efficacy, safety and cost-effectiveness of gefitinib with traditional chemotherapy in first-line treatment of EGFR-mutation advanced non-small cell lung cancer (NSCLC). Methods:A systematic review method was performed to search and retrieve the evidence from various databases including Pubmed, Medline, CNKI, etc. We collected English and Chinese studies during last decade on comparison of gefitinib with traditional chemotherapy in first-line treatment of NSCLC. Results:With inclusion and exclusion criteria, there were 5 clinical studies and 2 cost-effectiveness studies finally recruited for the analysis. Clinical results showed that progression-free survival and objective response rate favored gefitinib in the first-line treatment of EGFR-mutation NSCLC. Also gefitinib was proved to be superior to traditional chemotherapy in safety and improvement in quality of life. Two cost effectiveness studies revealed that from the perspective of UK NHS and Singapore society, gefitinib was cost effective compared with traditional chemotherapy. Conclusions:Gefitinib can be considered as a standard option in the first-line treatment of EGFR-mutation NSCLC. More evidences on cost and cost effectiveness of gefitinib for EGFR-mutation NSCLC patients in China are still needed to support clinical usage and local public decision making on health insurance benefits update in China.%目的:通过文献系统综述,对吉非替尼和普通化疗一线治疗EGFR突变阳性的晚期非小细胞肺癌的临床疗效、安全性、生命质量和成本-效果进行比较研究。方法:在Pubmed、Medline、中国期刊全文数据库(CNKI)等检索近10年发表的比较吉非替尼和化疗一线治疗晚期NSCLC的文献。结果:纳入临床研究5个,显示吉非替尼在改善无进展生存期和客观缓解率上好于化疗,安全性和生活质量的改善好于化疗。2个成本-效果研究

    Breast cancer is the leading cause of cancer among women worldwide and the most common cancer in China. Many factors influence the treatment strategy for metastatic breast cancer (MBC). Chemotherapy should be administered to patients with hormone receptor-negative tumors, symptomatic visceral metastasis, and a short disease-free interval. Sequential single-agent chemotherapy has similar efficacy as combination agents in terms of overall survival and quality of life. Anthracyclines are the cornerstone of first-line treatment for MBC, and taxanes represent the second treatment option after resistance. When progression or intolerable toxicity occurs after optimal treatment, the alternative treatments include capecitabine, vinorel-bine, and gemcitabine. Ixabepilone and eribulin are relatively new effective single agents. A combination of cytotoxic agents for patients with rapid clinical progression can further improve the overall response rate and time to progression compared to single-agent treatment. For patients with MBC who were pretreated with anthracyclines in the neoadjuvant/adjuvant setting, a taxane-containing regimen such as docetaxel plus capecitabine or gemcitabine plus paclitaxel should be administered. Platinum-based therapies such as cisplatin or carboplatin have a role in the treatment of triple-negative breast cancer. Meanwhile, the efficacy of the addition of targeted drugs such as iniparib, bevacizumab, and cetuximab to chemotherapy remains unproven. Maintenance chemotherapy is routinely recommended in clinical practice at present. Patients who were previously treated with paclitaxel and gemcitabine have better progression-free and overall survival with maintenance chemotherapy according to a Korean phase Ⅲ clinical trial. Sequential maintenance treatment with capecitabine monotherapy after capecitabine-based combination chemotherapy (X-based X) appears favorable based on a series of domestic studies.

    Full Text Available Abstract Background Arsenic exposure increases the risk of non-cancerous and cancerous diseases. In the Antofagasta region in Chile, an established relationship exists between arsenic exposure and the risk of cancer of the bladder, lung and skin. Platinum-based drugs are first-line treatments, and many works recognise selenium as a cancer-fighting nutrient. We characterised the short-term urinary excretion amounts of arsenic, selenium and platinum in 24-h urine samples from patients with lung cancer and those with cancer other than lung treated with cisplatin or/and carboplatin. As - Se - Pt inter-element relationships were also investigated. Results The amounts of platinum excreted in urine were not significantly different between patients with lung cancer and those with other cancers treated with cisplatin, despite the significant variation in platinum amounts supplied from platinum-based drugs. In general, the analytical amounts of excreted selenium were greater than those for arsenic, which could imply that platinum favours the excretion of selenium. For other types of cancers treated with drugs without platinum, excretion of selenium was also greater than that of arsenic, suggesting an antagonist selenium-anti-cancer drug relationship. Conclusions Regards the baseline status of patients, the analytical amounts of excreted Se is greater than those for As, particularly, for cisplatin chemotherapy. This finding could imply that for over the As displacement Pt favours the excretion of Se. The analytical amounts of excreted Se were greater than those for As, either with and without Pt-containing drugs, suggesting an antagonist Se-anti-cancer drug relationship. However, it seemed that differences existed between As - Se - Pt inter-element associations in patients treated for lung cancer in comparison with those treated for cancer other than lung. Therefore, knowledge obtained in this work, can contribute to understanding the arsenic cancer

    The paper will examines and discusses the results from a structured observational study, wherein 50 first-line managers from the public sector in Denmark in five areas of employment where observed. These observational studies are a key contribution in the ‘greenhouse for management’ project......, the study explores which tasks the managers primarily perform, divided into eight categories of activities. Third, it is examined how the manager’s usage of time is divided among the individual tasks. The results of the above data can be used both to provide a comprehensive characterization of municipal...... first-line managers’ work and to illuminate differences between first-line managers from different occupational groups. The second question relates to current debate about the degree of professionalized management among the municipal first-line managers. In both the international and Danish management...

    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.

    At the 4th Ovarian Cancer Consensus Conference of the Gynecologic Cancer InterGroup (GCIG) held in Vancouver, Canada, in June 2010, representatives of 23 cooperative research groups studying gynecologic cancers gathered to establish international consensus on issues critical to the conduct of large randomized trials. The process focused on 13 predetermined questions. Group A, 1 of the 3 discussion groups, addressed the first 5 questions, examining first-line therapies in newly diagnosed ovarian cancer patients. A1: What are the appropriate end points for different trials (maintenance, upfront chemotherapy trials including molecular drugs)? A2: Are there any subgroups defined by tumor biology who need specific treatment options/trials? A3: Is the 2004 GCIG-recommended standard comparator arm still valid? A4: What is the role of modifying dose, schedule, and delivery of chemotherapy? A5: What role does surgery play today?

    Since the approval of cisplatin as an antineoplastic drug, the medical and the scientific communities have been concerned about the side effects of platinum-based drugs, and this has been the dose-limiting factor that leads to reduced treatment efficiency. Another important issue is the intrinsic or acquired resistance of some patients to treatment. Identifying proper biomarkers is crucial in evaluating the efficiency of a treatment, assisting physicians in determining, at early stages, whether or not the patient presents resistance to the drug, minimizing severe side effects, and allowing them to redirect the established course of chemotherapy. A great effort is being made to identify biomarkers that can be used to predict the outcome of the treatment of cancer patients with platinum-based drugs. In this context, the metallomic approach has not yet been used to its full potential. Since the basis of these drugs is platinum, the monitoring of biomarkers containing this metal should be the natural approach to evaluate treatment progress. This review intends to show where the research in this field stands and points out some gaps that can be filled by metallomics.

    The platinum-based drugs cisplatin, carboplatin, and oxaliplatin belong to the most widely used chemotherapeutics in oncology, showing clinical efficacy against many solid tumors. Their main mechanism of action is believed to be the induction of cancer cell apoptosis as a response to their covalent

    Maintenance therapy improves outcomes in various tumour types, but cumulative toxic effects limit the choice of drugs. We investigated whether maintenance therapy with vinflunine would delay disease progression in patients with advanced urothelial carcinoma who had achieved disease control with first-line chemotherapy. We did a randomised, controlled, open-label, phase 2 trial in 21 Spanish hospitals. Eligible patients had locally advanced, surgically unresectable, or metastatic transitional-cell carcinoma of the urothelial tract, adequate organ function, and disease control after four to six cycles of cisplatin and gemcitabine (carboplatin allowed after cycle four). Patients were randomly assigned (1:1) to receive vinflunine or best supportive care until disease progression. We initially used block randomisation with a block size of six. Four lists were created for the two stratification factors of starting dose of vinflunine and presence of liver metastases. After a protocol amendment, number of cisplatin and gemcitabine cycles was added as a stratification factor, and eight lists were created, still with a block size of six. Finally, we changed to a minimisation procedure to reduce the risk of imbalance between groups. Vinflunine was given every 21 days as a 20 min intravenous infusion at 320 mg/m(2) or at 280 mg/m(2) in patients with an Eastern Cooperative Oncology Group performance status score of 1, age 75 years or older, previous pelvic radiotherapy, or creatinine clearance lower than 60 mL/min. The primary endpoint was median progression-free survival longer than 5·3 months in the vinflunine group, assessed by modified intention to treat. Comparison of progression-free survival between treatment groups was a secondary endpoint. This trial is registered with ClinicalTrials.gov, number NCT01529411. Between April 12, 2012, and Jan 29, 2015, we enrolled 88 patients, of whom 45 were assigned to receive vinflunine and 43 to receive best supportive care. One

    Objective To compare the therapeutic effects and toxic reactions of DP regimen (docetaxel plus cisplatin) and GP regimen (gemcitabine plus cisplatin) in the treatment of advanced stage non-small cell lung career (NSCLC). Methods A total of 79 patients with advanced stage NSCLC were treated by first-line chemotherapy for 4~6 weeks. The patients were divided into two groups: DP group (docetaxel plus cisplatin) and GP group (gemcitabine plus cisplatin). Patients in DP group (n=43) were treated by 75 mg/m2 docetaxel on day 1 plus 25 mg/m2 cisplatin on day I to day 3. Patients in GP group (n=36) were treated by 1000 mg/m2 gemcitabine on day 1 and day 8 plus 25 mg/m2 cisphtin on day 1 to day 3. Twenty-one days were a treatment cycle. The treatment response rate and survival rate were evaluated by the end of every two cycles. Results The response rate was 37.21% for DP group and 33.33% for GP group, with no statistically significant difference between the two groups (P>0.05). The response rate also had no statistically significant difference in adenocarcinoma and squamous carcinoma sub-groups. The main side effects were myelosup-pression, nausea and omiting. There was no statistically significant difference in Ⅲ ~Ⅳ grade thrombocytopenia and gastrointestinal side effects between the two groups. Conclusion Both DP regimen (docetaxel and cisplatin) and GP regimen (gemcitabine and cisplatin) in first-line chemotherapy have good therapeutic effects and toleranted toxic reactions in the treatment of advanced stage non-small cell lung cancer (NSCLC).%目的 比较多西他赛联合顺铂与吉西他滨联合顺铂一线治疗晚期非小细胞肺癌的疗效和不良反应.方法 晚期非小细胞肺癌患者79例,均接受4~6周期一线化疗.多西他赛联合顺铂组(DP组)43例:多西他赛75 mg/m2,第1天,顺铂25 mg/m2,第1~3天.吉西他滨联合顺铂组(GP组)36例:吉西他滨1 000 mg/m2,第1天、第8天,顺铂用量同DP组.21d为一个化疗周期,每2

    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

    含铂两药联合化疗方案目前仍是晚期非小细胞肺癌(NSCLC)的标准一线治疗方案,分子靶向药物为晚期NSCLC患者提供了新的治疗选择.临床研究证实,在晚期NSCLC患者的二线治疗中,表皮生长因子酪氨酸激酶抑制剂(EGFR-TKI)与标准化疗相比具有明确的非劣效性.然而,肿瘤组织标本检测显示EGFR基因突变阳性的NSCLC患者使用EGFR-TKI作为一线治疗的疗效更优.目前对于分子靶向药物用于NSCLC的一线治疗还是二线治疗尚存争议.本文对多项临床研究进行分析,以探讨EGFR-TKI用于NSCLC患者的治疗时机问题.%Platinum-based chemotherapy is still the standard first-line treatment for patients with advanced non-small cell lung cancer (NSCLC). Molecular targeted agents provide a new option for NSCLC patients. Clinical trial had shown that survival rate with epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) treatment was not inferior compared with platinum-based chemotherapy in second line NSCLC therapy. However, for the patients with EGFR gene mutation, a better outcome has been achieved with the use of EGFR-TKI as first-line treatment. Currently,controversy still exists in the use of EGFR-TKI for treatment of NSCLC as first-line or second-line therapy. In present paper, the optimal time to use EGFR-TKI for treatment of NSCLC has been discussed based on the analysis of a series of clinical trials.

    The purpose of this article is to provide updated recommendations for the treatment of patients with stage IV non-small-cell lung cancer. A literature search identified relevant randomized trials published since 2002. The scope of the guideline was narrowed to chemotherapy and biologic therapy. An Update Committee reviewed the literature and made updated recommendations. One hundred sixty-two publications met the inclusion criteria. Recommendations were based on treatment strategies that improve overall survival. Treatments that improve only progression-free survival prompted scrutiny of toxicity and quality of life. For first-line therapy in patients with performance status of 0 or 1, a platinum-based two-drug combination of cytotoxic drugs is recommended. Nonplatinum cytotoxic doublets are acceptable for patients with contraindications to platinum therapy. For patients with performance status of 2, a single cytotoxic drug is sufficient. Stop first-line cytotoxic chemotherapy at disease progression or after four cycles in patients who are not responding to treatment. Stop two-drug cytotoxic chemotherapy at six cycles even in patients who are responding to therapy. The first-line use of gefitinib may be recommended for patients with known epidermal growth factor receptor (EGFR) mutation; for negative or unknown EGFR mutation status, cytotoxic chemotherapy is preferred. Bevacizumab is recommended with carboplatin-paclitaxel, except for patients with certain clinical characteristics. Cetuximab is recommended with cisplatin-vinorelbine for patients with EGFR-positive tumors by immunohistochemistry. Docetaxel, erlotinib, gefitinib, or pemetrexed is recommended as second-line therapy. Erlotinib is recommended as third-line therapy for patients who have not received prior erlotinib or gefitinib. Data are insufficient to recommend the routine third-line use of cytotoxic drugs. Data are insufficient to recommend routine use of molecular markers to select chemotherapy.

    Pancreatoblastoma is a rare tumor and surgery with complete resection is the main treatment approach. Prognosis for patients with residual disease after surgery is usually dismal. A 14-year-old girl with pancreatoblastoma in the pancreatic body and tail was submitted to preoperative chemotherapy. She underwent surgery and the tumor was resected with microscopic margins. Postoperative chemotherapy was followed by high dose chemotherapy and autologous hematopoietic stem cell transplantation. After four years she remains very well with no evidence of disease. This is the first case reported of pancreatoblastoma that was treated with autologous hematopoietic stem cell transplantation as first line treatment without radiotherapy at the site of the microscopic disease.

    Full Text Available Context: The excision repair cross-complementation group 1 (ERCC1 codon 118 C/T polymorphism has been associated with clinical outcome in cancer patients treated with platinum chemotherapy. Ethnic differences in the frequency of this polymorphism have been observed in Caucasian and African populations. Aim: The aim of this study was to evaluate the frequency and survival benefit of the ERCC1 codon 118 C/T polymorphism in a high-altitude population with advanced gastric cancer. Materials and Methods: Polymerase chain reaction-restriction fragment length polymorphism was used to determine the frequency of ERCC1 118 codon C/T polymorphism in 206 advanced gastric cancer patients residing in the high-altitude Qinghai-Tibetan plateau. The influence of the ERCC1 codon 118 C/T polymorphism on its micro ribonucleic acid (mRNA and protein expression, clinicopathological features; response to the platinum-based combination chemotherapy, and the outcome was evaluated. Statistical Analysis: The Kaplan-Meier method was used for survival analysis. The correlation of ERCC1 codon 118 polymorphism with ERCC1 mRNA and protein expression, clinicopathological characteristics, and first-line oxaliplatin, 5-fluorouracil, and leucovorin (FOLFOX-4 response was determined by χ2 -test. Results and Conclusions: ERCC1 codon 118 C/T polymorphism was not associated with ERCC1 mRNA and protein expression, FOLFOX-4 response, and progression-free survival (PFS or overall survival (OS. High ERCC1 mRNA and protein expression levels were associated with significantly lower FOLFOX-4 responses, PFS, and OS. ERCC1 codon 118 C/T polymorphism is not an important prognostic marker for advanced gastric cancer. Determination of ERCC1 mRNA and protein levels may be beneficial in predicting the response and outcome of FOLFOX-4 therapy in gastric cancer.

    Dysregulated long noncoding RNAs (lncRNAs) are potential markers of several tumor prognoses. This study aimed to develop a lncRNA expression signature that can predict chemotherapeutic sensitivity for patients with advanced stage and high-grade serous ovarian cancer (HGS-OvCa) treated with platinum-based chemotherapy. The lncRNA expression profiles of 258 HGS-OvCa patients from The Cancer Genome Atlas were analyzed. Results revealed that an eight-lncRNA signature was significantly associated with chemosensitivity in the multivariate logistic regression model, which can accurately predict the chemosensitivity of patients [Area under curve (AUC) = 0.83]. The association of a chemosensitivity predictor with molecular subtypes indicated the excellent prognosis performance of this marker in differentiated, mesenchymal, and immunoreactive subtypes (AUC > 0.8). The significant correlation between ZFAS1 expression and chemosensitivity was confirmed in 233 HGS-OvCa patients from the Gene Expression Omnibus datasets (GSE9891, GSE63885, and GSE51373). In vitro experiments demonstrated that the ZFAS1 expression was upregulated by cisplatin in A2008, HeyA8, and HeyC2 cell lines. This finding suggested that ZFAS1 may participate in platinum resistance. Therefore, the evaluation of the eight-lncRNA signature may be clinically implicated in the selection of platinum-resistant HGS-OvCa patients. The role of ZFAS1 in platinum resistance should be further investigated.

    Since its approval for the first-line treatment of metastatic colorectal cancer (mCRC), bevacizumab has become a standard treatment option in combination with chemotherapy for patients with mCRC. Bevacizumab has demonstrated efficacy in combination with a number of different backbone chemotherapy regimens, and its widespread use has introduced several important questions regarding the selection and optimization of bevacizumab-based treatment regimens, its use in various patient populations, and the identification of associated adverse events. This review discusses the results of several phase II and phase III clinical trials, as well as large observational studies, to address the use of bevacizumab in the treatment of patients with mCRC in the first-line setting.

    The prognosis of locally advanced (T3/T4 or N1) and metastatic disease urothelial carcinoma is poor. In this retrospective study, we reviewed data about patients receiving third-line chemotherapy for metastatic disease, in view of the lack of data in this setting.We retrospectively analyzed medical records of patients with a pathologic diagnosis of urothelial carcinoma treated with systemic chemotherapy for metastatic disease at 4 participating Institutions between January, 2010, and January, 2015. Cox proportional hazards regression was used to evaluate the association of the chemotherapy agent used versus others with overall survival, adjusted for 5 externally validated prognostic factors in advanced urothelial carcinoma.Of 182 patients that received first-line chemotherapy/adjuvant chemotherapy as defined above, 116 patients (63.73%) received second-line salvage treatment. Fifty-two patients were finally included in this analysis, whereas 9 were excluded due to missing data. Third-line chemotherapy was based on cyclophosphamide, platinum, vinflunine, taxanes, and gemcitabine in 16, 12, 11, 10, and 3 patients, respectively. Median PFS (progression-free survival) and OS (overall survival) of the population were 13 (10-17) and 31 (28-36) weeks. Single-agent cyclophosphamide was associated with a PFS of 18 (13-22) and an OS of 38 (33-41) weeks, whereas platinum-based combinations were associated with a PFS of 5 weeks and an OS of 8 weeks. Multivariate analysis showed improved survival in patients treated with cyclophosphamide (hazard ratio (HR) = 0.42; 95% CI: 0.20-0.89; P = 0.025) and a worse survival in those treated with platinum-based regimens (HR: 4.37; 95% CI = 1.95-9.77; P < 0.01).We observed a significantly longer overall survival in patients receiving single-agent cyclophosphamide, with few grade 3 to 4 toxicities. Further studies should assess the efficacy of metronomic single-agent cyclophosphamide in advanced lines of treatment, as it may

    Background and objective The third generation single-agent drug has been recommended as a first-line chemotherapy for elderly patients with advanced non-small cell lung cancer (NSCLC). The aim of the current radomized trial is to compare the clinical efficacy and toxicities of single-agent paclitaxel liposome versus paclitaxel liposome plus oxaliplatin as a first-line chemotherapy for elderly patients. Methods Sixty-nine advanced NSCLC patients from July 2008 to August 2010, confirmed with pathology or cytology and had never received treatment, were randomly divided into two groups. The first group was given 135 mg/m2 of single-agent paclitaxel liposome on day 1 of each cycle. The second group was given 135 mg/m2 paclitaxel liposome plus 125 mg/m oxaliplatin on day 1 of each cycle. One cycle is composed of 21 days. Efficacy and toxicities could be evaluated after two or more cycles. Results No statistical differences were observed between the two groups in terms of efficacy (22.9% vs 35.3%, P=0.297), disease control rate (60.0% vs 70.6%, P=0.450), and 1-year survival rate (28.6% vs 41.2%, P=0.724). However, the group treated with paclitaxel liposome plus oxaliplatin had longer progression free survival (PFS) (5.0 months vs 3.5 months, P=0.024). In addition, the toxicities that occurred in the two groups were similar including leukocytopenia (P=0.808), thrombocytopenia (P>0.999), anemia (P=0.477), and nausea/vomiting (P=0.777). The number of neurotoxicity that occurred in the two groups were 33 and 3 (97.1% vs 8.6%, P<0.00l), respectively. However, all were grade I-II. Conclusion The clinical efficacy of paclitaxel liposome plus oxaliplatin as a first-line chemotherapy for elderly patients with advanced NSCLC is more better than that of the single-agent paclitaxel liposome. It prolongs PFS and is safe for clinical use.%背景与目的 目前推荐第三代药物单药治疗老年晚期非小细胞肺癌( non-small cell lung cancer,NSCLC),本研究旨在比较紫杉

    Epithelial ovarian cancer is initially a chemosensitive neoplasm, with overall response rates to systemic platinum-based therapy exceeding 80% in conjunction with cytoreductive surgery. However, long-term survival remains poor due to eventual tumor recurrence and emergence of drug resistance. While platinum (cisplatin or carboplatin) and taxanes remain at the core of primary treatment, there has been increased interest in the evaluation of doublet and triplet combinations with diverse cytotoxic agents, including docetaxel, topotecan, gemcitabine, and PEG-liposomal doxorubicin. This has been prompted by single-agent activity in the setting of recurrent platinum-resistant disease and encouraging data from nonrandomized phase I-II trials. As a result, beginning in 1998, the international cooperative groups collaborated on a series of phase III trials to improve long-term outcomes through the development of new platinum-based combinations. More than 10,000 women have been randomized on these trials, and preliminary data from several studies have been reported. Although final data are pending, there is not currently any evidence to recommend adopting a new two- or three-drug combination, and carboplatin with paclitaxel remains the standard regimen of choice. Rapid developments in molecular-targeted therapy are challenging our paradigm for future clinical trials, and our priorities need to be carefully considered.

    The prognosis for patients with glioblastoma remains poor with current treatments. Although platinum based drugs are sometimes offered at relapse, their efficacy in this setting is still disputed. In this study, we use convection-enhanced delivery (CED) to deliver the platinum-based drugs (cisplatin, carboplatin, and Lipoplatin™-liposomal formulation of cisplatin) directly into the tumor of F98 glioma-bearing rats that were subsequently treated with γ radiation (15 Gy). CED increased by factors varying between 17 and 111, the concentration of these platinum-based drugs in the brain tumor compared to intra-venous (i.v.) administration, and by 9- to 34-fold, when compared to intra-arterial (i.a.) administration. Furthermore, CED resulted in a better systemic tolerance to platinum drugs compared to their i.a. injection. Among the drugs tested, carboplatin showed the highest maximum tolerated dose (MTD). Treatment with carboplatin resulted in the best median survival time (MeST) (38.5 days), which was further increased by the addition of radiotherapy (54.0 days). Although the DNA-bound platinum adduct were higher at 4 h after CED than 24 h for carboplatin group, combination with radiotherapy led to similar improvement of median survival time. However, less toxicity was observed in animals irradiated 24 h after CED-based chemotherapy. In conclusion, CED increased the accumulation of platinum drugs in tumor, reduced the toxicity, and resulted in a higher median survival time. The best treatment was obtained in animals treated with carboplatin and irradiated 24 h later. PMID:25784204

    The response of tumor cells to platinum-based chemotherapy involves DNA repair mechanisms. Excision repair cross-complementation group 1 (ercc1) is one of the leading genes involved in DNA repair, and several studies have linked ercc1 to platinum resistance in cell lines and in human cancers....... A common single nucleotide polymorphism (SNP) of ercc1 at codon 118 has been proposed to impair ercc1 translation and reduce ERCC1 protein expression and consequently influence the response to platinum-based chemotherapy. The primary aim of the present study was to evaluate ERCC1 expression and ercc1 codon...... 118 polymorphism in epithelial ovarian cancer (EOC) and their possible predictive value in patients treated with platinum-based chemotherapy. Formalin-fixed, paraffin-embedded tissue sections from 159 patients with advanced EOC were used for immunohistochemistry. Ercc1 codon 118 SNP genotyping...

    The treatment of metastatic colorectal cancer (mCRC) has evolved considerably in the last decade, currently allowing most mCRC patients to live more than two years. Monoclonal antibodies targeting the epidermal growth factor receptor (EGFR) and vascular endothelial growth factor play an important role in the current treatment of these patients. However, only antibodies directed against EGFR have a predictive marker of response, which is the mutation status of v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS). Cetuximab has been shown to be effective in patients with KRAS wild-type mCRC. The CRYSTAL study showed that adding cetuximab to FOLFIRI (regimen of irinotecan, infusional fluorouracil and leucovorin) significantly improved results in the first-line treatment of KRAS wild-type mCRC. However, results that evaluate the efficacy of cetuximab in combination with oxaliplatin-based chemotherapy in this setting are contradictory. On the other hand, recent advances in the management of colorectal liver metastases have improved survival in these patients. Adding cetuximab to standard chemotherapy increases the response rate in patients with wild-type KRAS and can thus increase the resectability rate of liver metastases in this group of patients. In this paper we review the different studies assessing the efficacy of cetuximab in the first-line treatment of mCRC.

    Patients with advanced non-small cell lung cancer (NSCLC) generally require second-line treatment although their prognosis is poor. In this multicenter study, we aimed to detect the characteristics related to patients and disease that can predict the response to second-line treatments in advanced NSCLC. Data of 904 patients who have progressed after receiving first-line platinum-based chemotherapy in 11 centers with the diagnosis of stage IIIB and IV NSCLC and who were evaluated for second-line treatment were retrospectively analyzed. The role of different factors in determining the benefit of second-line treatment was analyzed. Median age of patients was 57 years (range 19-86). Docetaxel was the most commonly used (20.9 %, n = 189) single agent, while gemcitabine-platinum was the most commonly used (6.7 %, n = 61) combination chemotherapy regimen in second-line setting. According to survival analysis, median progression-free survival after first-line treatment (PFS2) was 3.5 months (standard error (SE) 0.2; 95 % confidence interval (CI), 3.2-3.9), median overall survival (OS) was 6.7 months (SE 0.3; 95 % CI, 6.0-7.3). In multivariate analysis, independent factors affecting PFS2 were found to be hemoglobin (Hb) level over 12 g/dl and treatment-free interval (TFI) longer than 3 months (p = 0.006 and 0.003, respectively). Similarly, in OS analysis, Hb level over 12 g/dl and time elapsed after the first-line treatment that is longer than 3 months were found to be independent prognostic factors (p = 0.0001 and 0.045, respectively). In light of these findings, determining and using the parameters for which the treatment will be beneficial prior to second-line treatment can increase success rate.

    Renin-angiotensin system (RAS) inhibitors are widely prescribed for treatment of hypertension, especially for diabetic patients on the basis of postulated advantages for the reduction of diabetic nephropathy and cardiovascular morbidity and mortality. Despite widespread use of angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) for hypertension in both diabetic and non-diabetic patients, the efficacy and safety of RAS inhibitors compared to other antihypertensive drug classes remains unclear. To evaluate the benefits and harms of first-line RAS inhibitors compared to other first-line antihypertensive drugs in patients with hypertension. We searched the Cochrane Hypertension Group's Specialised Register, MEDLINE, MEDLINE In-Process, EMBASE and ClinicalTrials.gov for randomized controlled trials up to November 19, 2014 and the Cochrane Central Register of Controlled Trials (CENTRAL) up to October 19, 2014. The WHO International Clinical Trials Registry Platform (ICTRP) is searched for inclusion in the Cochrane Hypertension Group's Specialised Register. We included randomized, active-controlled, double-blinded studies with at least six months follow-up in people with primary elevated blood pressure (≥130/85 mmHg), which compared first-line RAS inhibitors with other first-line antihypertensive drug classes and reported morbidity and mortality or blood pressure outcomes. Patients with proven secondary hypertension were excluded. Two authors independently selected the included trials, evaluated the risk of bias and entered the data for analysis. We included 42 studies, involving 65,733 participants, with a mean age of 66 years. Much of the evidence for our key outcomes is dominated by a small number of large studies at a low risk of bias for most sources of bias. Imbalances in the added second-line antihypertensive drugs in some of the studies were important enough for us to downgrade the quality of the evidence.Primary outcomes were

    Background The purpose of the study was to evaluate the role of neoadjuvant chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries in treating patients with advanced ovarian epithelial carcinoma.Methods Forty-two patients with advanced ovarian epithelial carcinoma (study group) were treated via the anterior branches of the bilateral internal iliac arteries after cytoreductive surgery and 7 courses of adjuvant platinum-based combination chemotherapy. Primary cytoreductive surgery was performed in 43 patients with advanced ovarian epithelial carcinoma (control group), and then followed by 8 courses of adjuvant platinum-based combination chemotherapy. The rate of optimal cytoreductive surgery, survival rate, blood loss during operation and operative time were investigated in the two groups. Statistical significance was asessed using Student's t test, the Chi-squre test and the log-rank test. Results In the study group, the rate of optimum debulking after platinum-based chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries was 71.43%(30/42) (χ2=10.06, P0.05).Conclusions Neoadjuvant platinum-based combination chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries is an alternative treatment for patients with advanced ovarian epithelial carcinoma, in whom the chance of optimal cytoreductive surgery is low. The treatment can reduce blood loss, decrease operative time, and increase the rate of optimal cytoreductive surgery; but the median survival can't be improved significantly.

    Full Text Available Metastatic pancreatic cancer is an aggressive malignancy that is difficult to treat. Gemcitabine monotherapy has been used first line and many contemporary treatment approaches have focused on gemcitabine plus experimental agents. The 2012 ASCO Gastrointestinal Cancers Symposium Abstract #213 is a study of gemcitabine with IPI-926, a novel hedgehog pathway inhibitor. Abstract #227 is a study of gemcitabine with 90Y-hPAM4 radioimmunotherapy with yttrium labeled anti-mucin humanized antibody. Abstract #296 is a study of gemcitabine with temsirolimus, an mTOR inhibitor. Gemcitabine and erlotinib has shown slight advantages to gemcitabine alone. Abstract #253 takes this one step further and evaluates gemcitabine and erlotinib with apricoxib, a COX-2 inhibitor. FOLFIRINOX has shown superiority to gemcitabine; however, doing so at the cost of significantly greater toxicity. Abstract #199, is a study which examines the cost effectiveness of first line FOLFIRINOX approaches. Another cost effective study is portrayed in Abstract #372, a study evaluating the survival of unresectable pancreatic cancer patients treated with gemcitabine and the disease course is followed clinically without radiographic follow-up.

    After description of the importance of EGFR mutations in non-small cell lung cancer and confirmation that tyrosine-kinase inhibitors are more beneficial than chemotherapy in patients with EGFR+ tumours, treatment with one of these drugs has become the standard recommendation. Despite this advance, patients continue to progress and consequently there is a need to search for alternative treatments. Some studies have analysed afatinib activity after first-generation TKI therapy, as well as its administration in combination with conventional chemotherapy. Afatinib produces significant response rates and progression-free survival times after the development of clinical resistance, which are independent of the presence of the T790M resistance mutation and can be attributed to continued pan-HER inhibition. In addition to the initial clinical trial, LUX-LUNG-1, data are available from the use of afatinib in routine clinical practice, within extended use programs. Overall, response rates of between 7 and 15% can be expected with a duration of approximately 24 months and a median progression-free time of about 4 months. A study combining afatinib with cetuximab has obtained a high response rate. Afatinib toxicity in second-line treatment is similar to that appears when the drug is used as first-line therapy (mainly mucocutaneous and diarrhoea) and can be managed with routine measures. In conclusion, afatinib should be considered as a treatment option in patients with EGFR mutations who show disease progression after a first tyrosine-kinase inhibitor.

    Full Text Available Abstract Background Taxane-platinum therapy (TP has replaced platinum-based therapy (PC or PAC, DNA damaging chemotherapy in the postoperative treatment of ovarian cancer patients; however, it is not always effective. TP53 protein plays a differential role in response to DNA-damaging agents and taxanes. We sought to define profiles of patients who benefit the most from TP and also of those who can be treated with PC. Methods We compared the effectiveness of PC/PAC (n = 253 and TP (n = 199 with respect to tumor TP53 accumulation in ovarian cancer patients with FIGO stage IIB-IV disease; this was a non-randomized retrospective study. Immunohistochemical analysis was performed on 452 archival tumors; univariate and multivariate analysis by the Cox's and logistic regression models was performed in all patients and in subgroups with [TP53(+] and without TP53 accumulation [TP53(-]. Results The advantage of taxane-platinum therapy over platinum-based therapy was seen in the TP53(+, and not in the TP53(- group. In the TP53(+ group taxane-platinum therapy enhanced the probability of complete remission (p = .018, platinum sensitivity (p = .014, platinum highly sensitive response (p = .038 and longer survival (OS, p = .008. Poor tumor differentiation diminished the advantage from taxane-platinum therapy in the TP53(+ group. In the TP53(- group PC/PAC was at least equally efficient as taxane-platinum therapy and it enhanced the chance of platinum highly sensitive response (p = .010. However, in the TP53(- group taxane-platinum therapy possibly diminished the risk of death in patients over 53 yrs (p = .077. Among factors that positively interacted with taxane-platinum therapy in some analyses were endometrioid and clear cell type, FIGO III stage, bulky residual tumor, more advanced age of patient and moderate tumor differentiation. Conclusion Our results suggest that taxane-platinum therapy is particularly justified in patients with TP53(+ tumors or older

    Introduction There are a limited number of paediatric antiretroviral drug options. Characterising the long term safety and durability of different antiretrovirals in children is important to optimise management of HIV infected children and to determine the estimated need for alternative drugs in paediatric regimens. We describe first-line antiretroviral therapy (ART) durability and reasons for discontinuations in children at two South African ART programmes, where lopinavir/ritonavir has been recommended for children <3 years old since 2004, and abacavir replaced stavudine as the preferred nucleoside reverse transcriptase inhibitor in 2010. Methods We included children (<16 years at ART initiation) who initiated ≥3 antiretrovirals between 2004–2014 with ≥1 follow-up visit on ART. We estimated the incidence of first antiretroviral discontinuation using Kaplan-Meier analysis. We determined the reasons for antiretroviral discontinuations using competing risks analysis. We used Cox regression to identify factors associated with treatment-limiting toxicity. Results We included 3579 children with median follow-up duration of 41 months (IQR 14–72). At ART initiation, median age was 44 months (IQR 13–89) and median CD4 percent was 15% (IQR 9–21%). At three and five years on ART, 72% and 26% of children respectively remained on their initial regimen. By five years on ART, the most common reasons for discontinuations were toxicity (32%), treatment failure (18%), treatment simplification (5%), drug interactions (3%), and other or unspecified reasons (18%). The incidences of treatment limiting toxicity were 50.6 (95% CI 46.2–55.4), 1.6 (0.5–4.8), 2.0 (1.2–3.3), and 1.3 (0.6–2.8) per 1000 patient years for stavudine, abacavir, efavirenz and lopinavir/ritonavir respectively. Conclusions While stavudine was associated with a high risk of treatment-limiting toxicity, abacavir, lopinavir/ritonavir and efavirenz were well-tolerated. This supports the World Health

    Tapentadol is the newest centrally acting analgesic to be approved by the US FDA and regulatory bodies in other countries. It has been called the first-in-class of a novel-acting analgesic mechanism of action that combines µ-opioid receptor agonist activity with neuronal norepinephrine-reuptake inhibition in a single molecule. This duality of action should combine inhibition of ascending (afferent) pain-transmitting signals with activation of descending (efferent) pain-attenuating systems (e.g., diffuse noxious inhibitory controls). However, not all novel mechanisms of action impart the characteristics needed for an analgesic to be considered for first-line therapy. These key questions may help inform clinical decision making.

    Chemotherapy plays a critical and venturous role against the co-morbidity of nonsmall cell lung cancer and interstitial lung disease (NSCLC-ILD).We performed a Bayesian meta-analysis and systematic review to evaluate the safety and efficacy of the chemotherapy in NSCLC-ILD patients.EMBASE, PubMed, the Cochrane Central Register of Controlled Trials, and clinicaltrials.gov (up to January 2015).We included all study designs except case reports, all studies with NSCLC-ILD patients and all the possible chemotherapy regimens.Quality was assessed by a components approach. We derived summary estimates using Bayesian method through WinBUGS (version 1.4.3, MRC Biostatistics Unit, Cambridge, UK).Seven studies involving 251 patients with NSCLC-ILD were included in the meta-analysis. The treatment response (complete remission, 0; [partial remission, 39.1%; 95% credible interval [CrI], 32.6-45.7]; [stable disease, 36%; 95% CrI, 29.6-42.2]; [PD, 15.4%; 95% CrI, 11.3-19.8]; [nonevaluable, 6.4%; 95% CrI, 2.7-10.1]; [overall response rate, 41.3%; 95% CrI, 35.3-47.4]; [disease control rate, 77.7%; 95% CrI, 72.2-82.7]) were comparable to that of patients with NSCLC alone; the survival outcomes (median overall survival, median progression-free survival, and 1-year survival rate) were slightly worse, especially the lower 1-year survival rate. Platinum-based doublets as first-line chemotherapy may be related to higher incidence of acute exacerbation-ILD in first line chemotherapy (AE, 8.47%; 95% CrI, 5.04-12.6).The data selection bias and small patient number make the meta-analysis of treatment response and conclusions generated from these data inaccurate.The present meta-analysis suggests that chemotherapy might be an effective therapy for patients with NSCLC-ILD, but it might be associated with higher incidence of acute exacerbation.

    The objective of the study is to determine whether surgery influences the outcome of stage IV ovarian cancer. The study design is as follows: From May 1995 to December 2000, 129 patients with FIGO stage IV ovarian cancer, recruited in 42 centers, were prospectively included in GINECO first-line randomized studies of platinum-based regimens with paclitaxel administered simultaneously or sequentially. In all, 109 were eligible for this study. Standard peritoneal cytoreductive surgery was defined as a procedure including at least total hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and peritoneal debulking. Surgery was considered optimal if residual lesions were smaller than 1 cm. The Kaplan-Meier method was used to compare survival. Initial abdominopelvic cytoreductive surgery was considered standard in 55 (54%) patients. Abdominopelvic surgery was optimal in 29 patients and nonoptimal in 26. Twenty-two (22%) patients had a simple biopsy, and 25 (24%) patients underwent substandard surgery. Twenty-two of these 47 patients without initial standard surgery underwent a second surgical procedure, and 17 of the 22 patients completed standard surgery. The median overall survival time in the entire population was 24.3 months (95% confidence interval [CI], 19.5-29.1 months). Patients treated without a cytoreductive surgical procedure had significantly worse median survival (15.1 months; 95% CI, 5.4-24.9 months) than patients who had optimal primary surgery (22.9 months; 95% CI, 15.6-30.1 months), nonoptimal primary surgery (27.1 months; 95% CI, 21.2-32.9 months), or neoadjuvant chemotherapy followed by surgery (45.5 months; 95% CI, 23.5-67.5 months) (P= .001). In conclusion, this study shows a significant benefit of debulking surgery in stage IV ovarian cancer patients who responded to neoadjuvant chemotherapy. Neoadjuvant chemotherapy can help to select patients for surgery.

    Background Endometrial adenocarcinoma (womb cancer) is a malignant growth of the lining (endometrium) of the womb (uterus). It is distinct from sarcomas (tumours of the uterine muscle). Survival depends the risk of microscopic metastases after surgery. Adjuvant (postoperative) chemotherapy improves survival from some other adenocarcinomas, and there is evidence that endometrial cancer is sensitive to cytotoxic therapy. This systematic review examines the effect of chemotherapy on survival after hysterectomy for endometrial cancer. Objectives To assess efficacy of adjuvant (postoperative) chemotherapy for endometrial cancer. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2010, Issue 3), MEDLINE and EMBASE up to August 2010, registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Selection criteria Randomised controlled trials (RCTs) comparing adjuvant chemotherapy with any other adjuvant treatment or no other treatment. Data collection and analysis We used a random-effects meta-analysis to assess hazard ratios (HR) for overall and progression-free survival and risk ratios (RR) to compare death rates and site of initial relapse. Main results Five RCTs compared no additional treatment with additional chemotherapy after hysterectomy and radiotherapy. Four trials compared platinum based combination chemotherapy directly with radiotherapy. Indiscriminate pooling of survival data from 2197 women shows a significant overall survival advantage from adjuvant chemotherapy (RR (95% CI) = 0.88 (0.79 to 0.99)). Sensitivity analysis focused on trials of modern platinum based chemotherapy regimens and found the relative risk of death to be 0.85 ((0.76 to 0.96); number needed to treat for an additional beneficial outcome (NNT) = 25; absolute risk reduction = 4% (1% to 8%)). The HR for overall survival is 0.74 (0.64 to 0.89), significantly

    2009-01-01

    Many patients with generalized anxiety disorder (GAD) do not receive adequate treatment. Several classes of drugs, including benzodiazepines, azapirones, selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, antihistamines, alpha(2)delta Ca++ channel modulators, and atypical antipsychotics are consistently beneficial in patients with GAD. Cognitive therapy is also effective as a first-line treatment. When individualizing treatment, drug dose ranges and side effect profiles need to be considered, as well as the patient's comorbid conditions. Doses may need to be reduced for elderly or medically ill patients or those taking other medications. Doses may need to be increased for refractory cases. Common comorbid conditions with GAD include depression, alcohol or drug abuse, social anxiety disorder, and panic disorder. In patients with significant depression, an antidepressant is more likely to succeed than a benzodiazepine. Generalized anxiety disorder is a chronic illness that requires long-term treatment. Remission is attainable but can take several months, and stopping medication increases the risk of relapse within the first year of initiating treatment.

    Ovarian cancer is an important health concern worldwide. The majority of patients present with advanced disease, and despite initial chemosensitivity, most relapse and die from their disease. Better therapeutic options are urgently required. Maximal surgical debulking in combination with platinum/taxane chemotherapy has been the standard of care in advanced ovarian cancer since the mid-1990s. Trials investigating the addition of a third chemotherapeutic agent have disappointingly failed to demonstrate benefit. Intra-peritoneal therapy demonstrated improvements in outcomes in some trials, but at the cost of increased toxicity and inconvenience. Encouragingly, prospective data has now demonstrated benefits with bevacizumab in both the first-line and relapsed settings; however, interpretation is complex, particularly considering recent data demonstrating non-inferiority of neo-adjuvant chemotherapy with delayed primary surgery, and other data demonstrating a substantial improvement in outcome as a result of first-line paclitaxel dose fractionation. This article reviews the recent advances in ovarian cancer treatment and discusses current management and key areas for future research.

    Prior to the recent therapeutic advances, chemotherapy was the mainstay of treatment options for advanced-stage melanoma. A number of studies have investigated various chemotherapy combinations in order to expand on the clinical responses achieved with single-agent dacarbazine, but these have not demonstrated an improvement in overall survival. Similar objective responses were observed with the combination of carboplatin and paclitaxel as were seen with single-agent dacarbazine. The combination of chemotherapy and immunotherapy, known as biochemo-therapy, has shown high clinical responses; however, biochemo-therapy has not been shown to improve overall survival and resulted in increased toxicities. In contrast, palliation and long-term responses have been observed with localized treatment with isolated limb perfusion or infusion in limb-isolated disease. Although new, improved therapeutic options exist for first-line management of advanced-stage melanoma, chemotherapy may still be important in the palliative treatment of refractory, progressive, and relapsed melanoma. We review the various chemotherapy options available for use in the treatment and palliation of advanced-stage melanoma, discuss the important clinical trials supporting the treatment recommendations, and focus on the clinical circumstances in which treatment with chemotherapy is useful.

    Full Text Available Objective: To evaluate the efficacy and adverse reactions of pemetrexed as the first-line treatment in elderly patients with advanced non-squamous non-small-cell lung cancer (NSCLC. Methods: The elderly patients with advanced non-squamous NSCLC received pemetrexed as the first-line treatment were retrospectively analyzed. All of them were intravenously injected 500 mg/ m2 pemetrexed, and 21 days were as one cycle. The efficiency was evaluated every two cycles till the disease progressed or sever adverse reactions occurred. The condition of adverse reactions as well as final outcome were observed. Results: Eighty-seven patients were enrolled in the research, totally receiving 392 cycles of chemotherapy, and the mean for 1 patient being 4.5 cycles. After 2 cycles of chemotherapy, partial response (PR and stable disease (SD were respectively 39 and 18 cases. The response rate and disease control rate were 44.8% and 65.5%, respectively. The median overall survival (OS of all patients was 16.1 months, and median progression-free survival (PFS was 3.2 months. Twenty-five patients completed 4 cycles of chemotherapy, and 32 patients completed 6 cycles of chemotherapy at least. The median OS of patients > 4 cycles of chemotherapy was 17.4 months, while those ≤ 4 cycles was 13.6 months, and the difference had statistical significance (χ2 = 4.374, P = 0.036. The major adverse reactions included myelosuppression, fatigue and gastrointestinal reactions, mainly at grades 1 - 2. No treatment-related deaths occurred. Conclusion: The efficiency of pemetrexed is definite as the first-line treatment in elderly patients with advanced non-squamous NSCLC, and the incidence of adverse reactions is low. The prognosis of patients is associated with cycles of pemetrexed chemotherapy.

    Tumor microenvironment is one of the major obstacles to the efficacy of chemotherapy in cancer patients. The abnormal blood flow within the tumor results in uneven drug distribution. Electrochemotherapy (ECT) is a tumor treatment that adopts the systemic or local delivery of anticancer drugs with the application of permeabilizing electric pulses having appropriate amplitude and waveforms. This allows the use of lipophobic drugs that frequently have a narrow therapeutic index maintaining at the same time a reduced patient morbidity and preserving appropriate anticancer efficacy. Its use in humans is addressed to the treatment of cutaneous neoplasms or the palliation of skin tumor metastases, and a standard operating procedure has been devised. On the other hand, in veterinary oncology this approach is gaining popularity, thus becoming a first line treatment for different cancer histotypes, in a variety of clinical conditions due to its high efficacy and low toxicity. This review summarizes the state of the art in veterinary oncology as a preclinical model and reports the new protocols in terms of drugs and therapy combination that have been developed.

    The efficacy and safety of capecitabine and bevacizumab in elderly patients with metastatic colorectal cancer (mCRC) considered unsuitable for receiving first-line chemotherapy with an irinotecan or oxaliplatin-based combination were assessed in a phase II, open, multicentre, uncontrolled study. Treatment consisted of capecitabine 1250 mg m(-2) (or 950 mg m(-2) for patients with a creatinine clearance of 30-50 ml min(-1)) twice daily on days 1-14 and bevacizumab (7.5 mg kg(-1)) on day 1 every 3 weeks. A total of 59 patients aged >or=70 years with mCRC were enrolled. In an intention-to-treat analysis, the overall response rate was 34%, with 71% of patients achieving disease control. Median progression-free survival and overall survival were 10.8 months and 18 months, respectively. In all, 32 patients (54%) had grade 3/4 adverse events (AEs), the most common being hand-foot syndrome (19%), diarrhoea (9%) and deep venous thrombosis (7%). Four patients died because of treatment-related AEs. A relationship was detected between creatinine clearance

    Despite recent advances in the primary and secondary prevention of cervical cancer, a significant number of women present with or develop metastatic disease. There is currently no consensus on the standard of care for second-line systemic treatment of recurrent/metastatic cervical cancer. The purpose of this study was to evaluate the second-line systemic therapy used and the associated outcomes in a single cancer centre. A retrospective review of patients with cervical cancer who received one or more lines of treatment for recurrent or metastatic cervical cancer at the Royal Marsden Hospital between 2004 and 2014 was carried out. The primary objective was to establish the types of second-line systemic treatment used. Secondary end points included objective response rate, progression-free survival and overall survival after second-line therapy. In total, 75 patients were included in the study; 53 patients (70.7%) received second-line therapy for recurrent/metastatic disease. The most common second-line therapy was weekly paclitaxel (28.3%). Carboplatin-based chemotherapy (24.5%), targeted agent monotherapy within clinical trials (22.6%), docetaxel-based chemotherapy (13.2%), topotecan (9.4%) and gemcitabine (1.9%) were also used. The objective response rate to second-line therapy was 13.2%, which included three partial responses to carboplatin and paclitaxel, two partial responses to docetaxel-based chemotherapy, one partial response to weekly paclitaxel and one partial response to cediranib. Twenty-two patients (41.5%) achieved stable disease at 4 months. The median progression-free survival for women treated with second-line therapy was 3.2 months (95% confidence interval 2.1-4.3) and median overall survival was 9.3 months (95% confidence interval 6.4-12.5). Thirty-nine per cent of patients received third-line therapy. Seventy per cent of patients treated with first-line systemic therapy for recurrent/metastatic cervical cancer subsequently received second

    A 52-year-old man was presented with a huge left testicular mass and palpable cervical lymphadenopathy with retroperitoneal lymph node enlargement on an abdominal computed tomography. A left radical orchiectomy and an ultrasound-guided neck node biopsy were performed. A pathological examination revealed spermatocytic seminoma with extensive rhabdomyosarcomatous transformation, a condition known to be highly resistant to platinum-based chemotherapy. The patient received four cycles of etoposide, ifosfamide and cisplatin (VIP) chemotherapy. A repeat computed tomography revealed a substantial regression consistent with a partial response. Retroperitoneal lymph node dissection was attempted, which revealed rhabdomyosarcoma; however, complete microscopic resection was not achieved. After surgery, the residual abdominal lymph node progressed and salvage paclitaxel, ifosfamide and cisplatin (TIP) chemotherapy was employed, which again achieved a partial response. Here, we present a first case report of a spermatocytic seminoma with extensive rhabdomyosarcomatous transformation and multiple metastatic lymphadenopathies that showed a favorable response to platinum-based systemic chemotherapy.

    Cisplatin is a widely used cancer chemotherapeutic that promotes DNA damage-associated apoptosis. Although platinum compounds are known to form DNA adducts and provoke DNA damage, the molecular mechanism of cisplatin-induced cell death remains unclear. In this article, we show that the BH3-only protein Noxa is strongly transcriptionally upregulated in response to cisplatin and related platinum compounds. Cisplatin-induced Noxa expression was ERK dependent, but p53 independent, and inhibition of ERK activation markedly attenuated cisplatin-induced cell death, as well as Noxa expression. Furthermore, siRNA-mediated ablation of Noxa expression also inhibited cisplatin-induced cell death and permitted clonogenic survival. These observations reveal a novel ERK-regulated route to Noxa expression that is important for the cell killing activity of platinum-based chemotherapeutic drugs.

    The nano-sized platinum based catalysts using high surface area silica support have been prepared by sol-gel method. Tetramethoxysilane (TMOS) diluted in methanol was hydrolyzed to form a porous silica gel. Platinum (2%) was loaded at sol state using platinum chloride solution. After gelation, the solvent from the gel pores was extracted at ambient temperature which resulted in porous silica matrix incorporated with nanosized platinum. X-ray diffraction studies indicated the presence of elemental platinum in the silica-platinum composites. Transmission electron microscopy of the platinum -silica composites revealed that nanosized platinum particles of about 5-10 nm are homogeneously dispersed in silica matrix. Chemisorptions studies showed high dispersion (more than 50%) of platinum on silica support with specific surface area of 400 m2/g which puts them as promising candidates as catalyst in heterogeneous reactions.

    The phamacogenetics is being used to predict whether the selected chemotherapy will be really effective and tolerable to the patient.

    Full Text Available Platinum-based chemotherapy is commonly used for the treatment of locally advanced and metastatic bladder cancer. However, there are currently no methods to predict chemotherapy response in this disease setting. A better understanding of the biology of bladder cancer has led to developments of molecular biomarkers that may help guide clinical decision making. These biomarkers, while promising, have not yet been validated in prospective trials and are not ready for clinical applications. As alkylating agents, platinum drugs kill cancer cells mainly through induction of DNA damage. A microdosing approach is currently being tested to determine if chemoresistance can be identified by measuring platinum-induced DNA damage using highly sensitive accelerator mass spectrometry technology. The hope is that these emerging strategies will help pave the road towards personalized therapy in advanced bladder cancer.

    Full Text Available Platinum derivatives used as chemotherapeutic drugs such as cisplatin and oxaliplatin have a potent antitumor activity. However, severe side effects such as nephro-, oto-, and neurotoxicity are associated with their use. Effects and side effects of platinum-based drugs are in part caused by their transporter-mediated uptake in target and non target cells. In this mini review, the transport systems involved in cellular handling of platinum derivatives are illustrated, focusing on transporters for cisplatin. The copper transporter 1 seems to be of particular importance for cisplatin uptake in tumor cells, while the organic cation transporter (OCT 2, due to its specific organ distribution, may play a major role in the development of undesired cisplatin side effects. In polarized cells, e.g. in renal proximal tubule cells, apically expressed transporters, such as multidrug and toxin extrusion protein 1, mediate secretion of cisplatin and in this way contribute to the control of its toxic effects. Specific inhibition of cisplatin uptake transporters such as the OCTs may be an attractive therapeutic option to reduce its toxicity, without impairing its antitumor efficacy.

    Due to the greenhouse effect, hydrogen production from bioethanol reforming is a very important subject in heterogeneous catalysis research. Pt based catalysts are employed in H{sub 2} purification processes and also as electrocatalysts of PEM (''Proton Exchange Membrane'') fuel cells. Hydrogen obtained from ethanol reforming may contain, as contaminants, acetaldehyde and small amounts of CO. This aldehyde can be decarbonylated on Pt based catalysts generating carbon monoxide and methane, rendering the hydrogen purification more challenging. Moreover, acetaldehyde might also change the electrocatalyst behavior. Therefore, this contribution aims at studying the acetaldehyde behavior in the presence of platinum based catalysts in hydrogen atmosphere. The Pt/SiO{sub 2}, Pt/USY catalysts and an electrocatalyst were characterized by n-butylamine, H{sub 2} and CO{sub 2} adsorption, ATG/DTG measurements and cyclohexane dehydrogenation reaction. It was observed that the acid-basic properties of the supports promote condensation reactions. When in contact with Pt based catalysts, acetaldehyde undergoes C-C and C=O bond scissions. The former occurs at a wide range of temperatures, whereas the latter only at low temperatures (<200 C). The C-C bond scission (decarbonylation) produces methane and CO. The C=O bond scission generates carbon residues on the catalyst as well as oxygen species, which in turn is able to eliminate CO from the catalytic surface. The data also show that decarbonylation is not a structure-sensitive reaction. (author)

    To examine the effect of chemical treatment on the adsorption and catalytic activity of nanostructured platinum based catalyst, the aged commercial Pt/AC catalyst was pretreated with sulfuric acid (H2SO4) and a cleaning agent (Hexane). Several reliable methods such as nitrogen adsorption, X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and inductively coupled plasma (ICP) were employed to characterize the aged Pt/AC catalyst and its chemically pretreated Pt/AC catalysts. The catalytic and adsorption activities of nano-structured heterogeneous Pt/AC catalyst were investigated on the basis of toluene oxidation and adsorption isotherm data. In addition, the adsorption isotherms of toluene were used to calculate the adsorption energy distribution functions for the parent catalyst and its pre-treated nano-structured Pt/AC catalysts. It was found that sulfuric acid aqueous treatment can enhance the catalytic performance of aged Pt/AC catalyst toward catalytic oxidation of toluene. It was also shown that a comparative analysis of the energy distribution functions for nano-structured Pt/AC catalysts as well as the pore size distribution provides valuable information about their structural and energetic heterogeneity.

    Breast cancer (BC) is the most common cause of cancer-related death worldwide. Although platinum-based drugs (PBDs) are effective anticancer agents, responsive patients eventually become resistant. While resistance of some cancers to PBDs has been explored, the cellular responses of BC cells are not studied yet. Therefore, we aim to assess the differential effects of PBDs on BC ultrastructure. Three representative cells were treated with different concentrations and timing of Cisplatin, Carboplatin, and Oxaliplatin. Changes on cell surface and ultrastructure were detected by scanning (SEM) and transmission electron microscope (TEM). In SEM, control cells were semiflattened containing microvilli with extending lamellipodia while treated ones were round with irregular surface and several pores, indicating drug entry. Prolonged treatment resembled distinct apoptotic features such as shrinkage, membrane blebs, and narrowing of lamellipodia with blunt microvilli. TEM detected PBDs' deposits that scattered among cellular organelles inducing structural distortion, lumen swelling, chromatin condensation, and nuclear fragmentation. Deposits were attracted to fat droplets, explained by drug hydrophobic properties, while later they were located close to cell membrane, suggesting drug efflux. Phagosomes with destructed organelles and deposits were detected as defending mechanism. Understanding BC cells response to PBDs might provide new insight for an effective treatment.

    To determine whether conformity to standard recommendations of retroperitoneal lymph node dissection (RPLND) after chemotherapy for testicular and primary retroperitoneal nonseminomatous germ cell tumours (NSGCT) and completeness of surgical excision have an effect on oncological outcome. This was a retrospective study of patients with testicular and primary retroperitoneal NSGCT, with initial involvement of RPLNs, treated between June 1992 and December 2002 in one institution. We reviewed the clinical, surgical and histological charts of 151 such patients who had a RPLND after first-line platinum-based chemotherapy. The recommendations used to define conformity to RPLND standards were: the indication based on initial and residual lymph node size, shrinkage, extension of dissection and completeness of resection. RPLND conformed to standard recommendations in 70 of the 151 (46%) patients. Conformity was complete for the surgeon who operated on 48 patients and was 26% of the others. Fifteen patients (10%) relapsed in the retroperitoneum, 14 of whom had initial lymph nodes of > or =5 cm. Two patients (3%) relapsed in the group of 70 patients with conformed and complete RPLND, vs 13 (16%) in the 81 with conformed but incomplete resection or with non-conformed and complete or incomplete RPLND. After a median (range) follow-up of 77 (1.3-186.5) months 132 patients were alive with no evidence of disease, 18 died and one was alive with progressive disease. The limitations of this study were the relatively few patients and that it was retrospective. There was conformity of RLNPD to the recommendations, and completeness of resection, in half of the patients operated; this might have an effect on oncological outcome. Our data suggest that patients should be treated in tertiary centres.

  12. Nano-structured Platinum-based Catalysts for the Complete Oxidation of Ethylene Glycol and Glycerol

    Science.gov (United States)

    Falase, Akinbayowa

    Direct alcohol fuel cells are a viable alternative to the traditional hydrogen PEM fuel cell. Fuel versatility, integration with existing distribution networks, and increased safety when handling these fuels increases their appeal for portable power applications. In order to maximize their utility, the liquid fuel must be fully oxidized to CO2 so as to harvest the full amount of energy. Methanol and ethanol are widely researched as potential fuels to power these devices, but methanol is a toxic substance, and ethanol has a much lower energy density than other liquids such as gasoline or glucose. Oxidation of complex fuels is difficult to realize, due to difficulty in breaking carbon-carbon bonding and poisoning of the catalysts by oxidative byproducts. In order to achieve the highest efficiency, an anode needs to be engineered in such a way as to maximize activity while minimizing poisoning effects of reaction byproducts. We have engineered an anode that uses platinum-based catalysts that is capable of completely oxidizing ethylene glycol and glycerol in neutral and alkaline media with little evidence of CO poisoning. We have constructed a hybrid anode consisting of a nano-structured PtRu electrocatayst with an NAD-dependent alcohol dehydrogenase for improved oxidation of complex molecules. A nano-structured PtRu catalyst was used to oxidize ethylene glycol and glycerol in neutral media. In situ infrared spectroscopy was used to verify complete oxidation via CO2 generation. There was no evidence of poisoning by CO species. A pH study was performed to determine the effect of pH on oxidative current. The peak currents did not trend at 60 mV/pH unit as would be expected from the Nernst equation, suggesting that adsorption of fuel to the surface of the electrode is not an electron-transfer step. We synthesized nano-structured PtRu, PtSn, and PtRuSn catalysts for oxidation of ethylene glycol and glycerol in alkaline media. The PtRu electrocatalyst the highest oxidative

The purpose of this study was to determine the proportion of senior hypertensives that received thiazide diuretics as first-line treatment, and to determine if cardiovascular and other potentially relevant comorbidities predict the choice of first-line therapy. Methods and Findings British Columbia PharmaCare data were used to determine the cohort of seniors (residents aged 65 or older who received their first reimbursed hypertension drug during the period 1993 to 2000. These individual records were linked to medical and hospital claims data using the British Columbia Linked Health Database to find the subset that had diagnoses indicating the presence of hypertension as well as cardiovascular and other relevant comorbidities. Rates of first-line thiazide prescribing as proportion of all first-line treatment were analysed, accounting for patient age, sex, overall clinical complexity, and potentially relevant comorbidities. For the period 1993 to 2000, 82,824 seniors who had diagnoses of hypertension were identified as new users of hypertension drugs. The overall rate at which thiazides were used as first-line treatment varied from 38% among senior hypertensives without any potentially relevant comorbidity to 9% among hypertensives with previous acute myocardial infarction. The rate of first-line thiazide diuretic prescribing for patients with and without potentially relevant comorbidities increased over the study period. Women were more likely than men, and older patients were more likely than younger, to receive first-line thiazide therapy. Conclusions Findings indicate that first-line prescribing practices for hypertension are not consistent with the evidence from randomized control trials measuring morbidity and mortality.

    To evaluate risk factors for GI adverse events (AEs) within a phase III trial of bevacizumab in first-line ovarian cancer therapy. Women with previously untreated advanced disease after surgery were randomly allocated to six cycles of platinum-taxane chemotherapy plus placebo cycles (C)2 to C22 (R1); chemotherapy plus bevacizumab C2 to C6 plus placebo C7 to C22 (R2); or chemotherapy plus bevacizumab C2 to C22 (R3). Patients were evaluated for history or on-study development of potential risk factors for GI AEs defined as grade ≥ 2 perforation, fistula, necrosis, or hemorrhage. Of 1,873 patients enrolled, 1,759 (94%) were evaluable, and 2.8% (50 of 1,759) experienced a GI AE: 10 of 587 (1.7%, R1), 20 of 587 (3.4%, R2), and 20 of 585 (3.4%, R3). Univariable analyses indicated that previous treatment of inflammatory bowel disease (IBD; P = .005) and small bowel resection (SBR; P = .032) or large bowel resection (LBR; P = .012) at primary surgery were significantly associated with a GI AE. The multivariable estimated relative odds of a GI AE were 13.4 (95% CI, 3.44 to 52.3; P GI AEs in patients receiving first-line platinum-taxane chemotherapy for advanced ovarian cancer. After accounting for these risk factors, concurrent bevacizumab doubles the odds of a GI AE, but is not appreciably increased by continuation beyond chemotherapy.

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

    Full Text Available Seigo Minami, Yoshitaka Ogata, Suguru Yamamoto, Kiyoshi Komuta Department of Respiratory Medicine, Osaka Police Hospital, Osaka, Japan Background: Advanced non-small-cell lung cancer (NSCLC eventually progresses after first-line chemotherapy, and usually requires salvage treatment. Although neither gemcitabine nor vinorelbine is approved as a candidate drug in the second- or further-line for NSCLC, they can be alternative drugs in terms of anti-tumor effects and toxicities. Actually, in our institution, we often use a combination of these two anti-tumor drugs in our daily practice. Methods: We retrospectively reviewed 85 patients with advanced NSCLC who had received combination chemotherapy of gemcitabine and vinorelbine after a platinum-based regimen from June 2007 to June 2014 in Osaka Police Hospital, and performed Cox proportional hazard analyses in order to detect predictive factors for progression-free survival (PFS. Results: Patient characteristics included a mean age of 65.5 years, 56 males, 54 adenocarcinoma, 53 European Clinical Oncology Group performance status 0–1. Thirteen and 35 patients received the study treatment as the second- and third-line treatment, respectively. The overall response rate, disease control rate, PFS, and overall survival were 4.7% (95% confidence interval 1.3%–11.6%, 30.6% (21.0%–41.5%, 2.1 months (1.7–2.8 months, and 6.9 months (5.0–11.0 months.

    The aim of this study was to investigate first-line nursing home managers' views on their leadership and related to that, palliative care. Previous research reveals insufficient palliation, and a number of barriers towards implementation of palliative care in nursing homes. Among those barriers are issues related to leadership quality. First-line managers play a pivotal role, as they influence working conditions and quality of care. Nine first-line managers, from different nursing homes in Sweden participated in the study. Semi-structured interviews were conducted and analysed using qualitative descriptive content analysis. In the results, two categories were identified: embracing the role of leader and being a victim of circumstances, illuminating how the first-line managers handle expectations and challenges linked to the leadership role and responsibility for palliative care. The results reveal views corresponding to committed leaders, acting upon demands and expectations, but also to leaders appearing to have resigned from the leadership role, and who express powerlessness with little possibility to influence care. The first line managers reported their own limited knowledge about palliative care to limit their possibilities of taking full leadership responsibility for implementing palliative care principles in their nursing homes. The study stresses that for the provision of high quality palliative care in nursing homes, first-line managers need to be knowledgeable about palliative care, and they need supportive organizations with clear expectations and goals about palliative care. Future action and learning oriented research projects for the implementation of palliative care principles, in which first line managers actively participate, are suggested.

    Full Text Available Platinum-based cytostatics, such as cisplatin, carboplatin or oxaliplatin are widely used agents in the treatment of various types of tumors. Large amounts of these drugs are excreted through the urine of patients into wastewaters in unmetabolised forms. This phenomenon leads to increased amounts of platinum ions in the water environment. The impacts of these pollutants on the water ecosystem are not sufficiently investigated as well as their content in water sources. In order to facilitate the detection of various types of platinum, we have developed a new, rapid, screening flow injection analysis method with electrochemical detection (FIA-ED. Our method, based on monitoring of the changes in electrochemical behavior of analytes, maintained by various pH buffers (Britton-Robinson and phosphate buffer and potential changes (1,000, 1,100 and 1,200 mV offers rapid and cheap selective determination of platinum-based cytostatics and platinum chlorides, which can also be present as contaminants in water environments.

    Platinum-based chemotherapy, with cytoreductive surgery, is the cornerstone of treatment of advanced ovarian cancer, however acquired drug resistance is a major clinical obstacle. It has been proposed that subpopulations of tumour cells with stem-cell like properties, such as so-called side populations (SP) which over-express ABC drug-transporters, can sustain the growth of drug resistant tumour cells, leading to tumour recurrence following chemotherapy. The histone methyltransferase EZH2 is a key component of the Polycomb Repressive Complex 2 (PRC2) required for maintenance of a stem cell state and overexpression has been implicated in drug resistance and shorter survival of ovarian cancer patients. We observe higher percentage SP in ascites from patients that have relapsed following chemotherapy compared to chemonaive patients, consistent with selection for this subpopulation during platinum-based chemotherapy. Furthermore, ABCB1 (P-glycoprotein) and EZH2 are consistently over-expressed in SP compared to non-SP from patients’ tumour cells. SiRNA knockdown of EZH2 leads to loss of SP in ovarian tumour models, reduced anchorage-independent growth and reduced tumour growth in vivo. Together these data support a key role for EZH2 in the maintenance of a drug-resistant tumour-sustaining subpopulation of cells in ovarian cancers undergoing chemotherapy. As such, EZH2 is an important target for anticancer drug development. PMID:21216927

    Full Text Available Introduction. Malignant pleural mesothelioma (MPM is associated with a poor prognosis. Palliative platinum-based chemotherapy may help to improve symptoms and prolong life. Since 2004, the platinum is commonly partnered with a folate antimetabolite. We performed a review investigating if survival had significantly changed before and after the arrival of folate antimetabolites in clinical practice. Methods. All MPM patients from January 1991 to June 2012 were identified. Data collected included age, gender, asbestos exposure, presenting signs/symptoms, performance status, histology, stage, bloodwork, treatment modalities including chemotherapy, and date of death or last follow-up. The primary endpoint was overall survival. Cox models were applied to determine variables associated with survival. Results. There were 245 patients identified. Median overall survival for all patients was 9.4 months. After multivariate analysis, performance status, stage, histology, leucocytosis, and thrombophilia remained independently associated with survival. Among all patients who received chemotherapy, there was no difference in overall survival between the periods before and after folate antimetabolite approval: 14.2 versus 13.2 months (P=0.35. Specifically receiving combined platinum-based/folate antimetabolite chemotherapy did not improve overall survival compared to all other chemotherapy regimens: 14.1 versus 13.6 months (P=0.97. Conclusions. In this review, we did not observe an incremental improvement in overall survival after folate antimetabolites became available.

O paciente com MM assintomático não deve receber tratamento ao diagnóstico, mas apenas quando surgirem indicações. Para o paciente sintomático (anemia, hipercalcemia, alteração da função renal, presença de lesões líticas ou plasmocitoma extramedular, aumento progressivo do componente-M no soro e/ou urina, o tratamento deverá ser rapidamente instituído. Aqueles pacientes com menos de 65-70 anos, com bom performance status, sem comorbidades e com função renal próxima do normal são potencialmente candidatos à consolidação com altas doses de quimioterapia seguidas de transplante autólogo de células-tronco hematopoéticas. Portanto, não devem utilizar drogas alquilantes para evitar prejuízos à mobilização das células-tronco. São opções: dexametasona, VAD e talidomida (com ou sem dexametasona. Os pacientes com mais de 65-70 anos, com performance status ruim, comorbidades e com função renal alterada podem receber tratamento com agentes alquilantes (por exemplo, melfalano e prednisona, com ou sem talidomida pois não serão submetidos a transplante. O principal objetivo nesses casos é atingir resposta com mínima toxicidade.The aim of this review is to evaluate the current status of first line treatment in multiple myeloma. Asymptomatic patients should not receive treatment at diagnosis. However, symptomatic patients (anemia, hypercalcemia, deterioration in renal function, lytic lesions or extramedullary plasmacytomas, increase of M-component in serum or urine should receive treatment as soon as possible. Patients younger than 65-70 years old with good performance status, no concurrent diseases and normal renal function are possible candidates for consolidation using high-dose chemotherapy followed by stem-cell transplantation. Therefore, they should not receive drugs that could potentially interfere with

    Full Text Available BACKGROUND: The aim was to analyse trends in clinically relevant resistance to first-line antiretroviral drugs in Spain, applying the Stanford algorithm, and to compare these results with reported Transmitted Drug Resistance (TDR defined by the 2009 update of the WHO SDRM list. METHODS: We analysed 2781 sequences from ARV naive patients of the CoRIS cohort (Spain between 2007-2011. Using the Stanford algorithm "Low-level resistance", "Intermediate resistance" and "High-level resistance" categories were considered as "Resistant". RESULTS: 70% of the TDR found using the WHO list were relevant for first-line treatment according to the Stanford algorithm. A total of 188 patients showed clinically relevant resistance to first-line ARVs [6.8% (95%Confidence Interval: 5.8-7.7], and 221 harbored TDR using the WHO list [7.9% (6.9-9.0]. Differences were due to a lower prevalence in clinically relevant resistance for NRTIs [2.3% (1.8-2.9 vs. 3.6% (2.9-4.3 by the WHO list] and PIs [0.8% (0.4-1.1 vs. 1.7% (1.2-2.2], while it was higher for NNRTIs [4.6% (3.8-5.3 vs. 3.7% (3.0-4.7]. While TDR remained stable throughout the study period, clinically relevant resistance to first line drugs showed a significant trend to a decline (p = 0.02. CONCLUSIONS: Prevalence of clinically relevant resistance to first line ARVs in Spain is decreasing, and lower than the one expected looking at TDR using the WHO list. Resistance to first-line PIs falls below 1%, so the recommendation of screening for TDR in the protease gene should be questioned in our setting. Cost-effectiveness studies need to be carried out to inform evidence-based recommendations.

    Full Text Available Introduction: A substantial number of patients with HIV in South Africa have failed first-line antiretroviral therapy (ART. Although individual predictors of first-line ART failure have been identified, few studies in resource-limited settings have been large enough for predictive modelling. Understanding the absolute risk of first-line failure is useful for patient monitoring and for effectively targeting limited resources for second-line ART. We developed a predictive model to identify patients at the greatest risk of virologic failure on first-line ART, and to estimate the proportion of patients needing second-line ART over five years on treatment. Methods: A cohort of patients aged ≥18 years from nine South African HIV clinics on first-line ART for at least six months were included. Viral load measurements and baseline predictors were obtained from medical records. We used stepwise selection of predictors in accelerated failure-time models to predict virologic failure on first-line ART (two consecutive viral load levels >1000 copies/mL. Multiple imputations were used to assign missing baseline variables. The final model was selected using internal-external cross-validation maximizing model calibration at five years on ART, and model discrimination, measured using Harrell's C-statistic. Model covariates were used to create a predictive score for risk group of ART failure. Results: A total of 72,181 patients were included in the analysis, with an average of 21.5 months (IQR: 8.8–41.5 of follow-up time on first-line ART. The final predictive model had a Weibull distribution and the final predictors of virologic failure were men of all ages, young women, nevirapine use in first-line regimen, low baseline CD4 count, high mean corpuscular volume, low haemoglobin, history of TB and missed visits during the first six months on ART. About 24.4% of patients in the highest quintile and 9.4% of patients in the lowest quintile of risk were predicted

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

    Mintzberg proposed that managers at all levels enact ten roles. There is, however, a relative importance ascribed to the various roles given the manager's location in the hierarchy. Like Mintzberg's ideas on the utility of ten roles, we found that managers at all levels, to varying degrees, need the three skills proposed by Katz. We have argued that a variety of roles and skills describe what managers do. At the same time, the predominance of one role or skill over another may be influenced by the location of the manager in the hierarchy. The question is not whether roles would be enacted at different levels or whether skills will be required, but whether one role or skill or a set of roles and skills will be predominant for the first-line supervisor. The first-line supervisor's work requires that he or she be predominantly proficient in the areas of human and technical skills in order to fulfill supervisory responsibilities. Current empirical research supports this assertion; however, the continuing study of managerial roles and skills and other variables such as functional specialty will offer other opportunities for the study of first-line supervisors. For example, will the predominance of the roles and skills that we have discussed vary if the supervisor is a line or staff manager or if the supervisor works in a production or service related organization? Organizations adapt to change to meet the expectations of those within and outside the organization with something at stake. Organizations need managers to facilitate the realization of organizational goals, so organizations need to continuously train managers, targeting appropriate roles and skills given each manager's location in the hierarchy. The preceding pages should provide resource materials to individuals and organizations interested in evaluating and designing the training and development of first-line supervisors. This roles-and-skills information can be productively utilized to assist the

    Full Text Available The management of retinoblastoma (RB has dramatically changed over the past two decades from previous radiotherapy methods to current chemotherapy strategies. RB is a remarkably chemotherapy-sensitive tumor. Chemotherapy is currently used as a first-line approach for children with this malignancy and can be delivered by intravenous, intra-arterial, periocular, and intravitreal routes. The choice of route for chemotherapy administration depends upon the tumor laterality and tumor staging. Intravenous chemotherapy (IVC is used most often in bilateral cases, orbital RB, and as an adjuvant treatment in high-risk RB. Intra-arterial chemotherapy (IAC is used in cases with group C or D RB and selected cases of group E tumor. Periocular chemotherapy is used as an adjunct treatment in eyes with group D and E RB and those with persistent/recurrent vitreous seeds. Intravitreal chemotherapy is reserved for eyes with persistent/recurrent vitreous seeds. In this review, we describe the various forms of chemotherapy used in the management of RB. A database search was performed on PubMed, using the terms "RB," and "treatment," "chemotherapy," "systemic chemotherapy," "IVC," "IAC," "periocular chemotherapy," or "intravitreal chemotherapy." Relevant English language articles were extracted, reviewed, and referenced appropriately.

    Interaction of cis-platin and neda-platin, two conventional platinum-based anticancer drugs, with pristine [8,8] and Al-doped [8,0] boron nitride nanotubes (BNNTs) are investigated using the density functional theory (DFT) method. The obtained results indicate that cis-platin and neda-platin weakly interact with pristine zig zag or armchair BNNTs with a little dependency on the adsorbing positions; while both cis-platin and neda-platin are preferentially adsorbed onto the Al atom of the Al-doped BNNT with considerable adsorption energies. Therefore the Al-doped-BNNT might be an efficient carrier for delivery of these drugs in nanomedicine domain. The electronic structures of the stable configurations are also investigated through both DOS and PDOS spectra. The obtained results introduce the Al-doped-BNNT as an efficient carrier for delivery of cis-platin and neda-platin in nanomedicine domain.

    Three molecular targeted tyrosine kinase inhibitors (TKI) were conjugated to classical platinum-based drugs with an aim to circumvent TKI resistance, predominately mediated by the emergence of secondary mutations on oncogenic kinases. The hybrids were found to maintain specificity towards the same oncogenic kinases as the original TKI. Importantly, they are remarkably less affected by TKI resistance, presumably due to their unique structure and the observed dual mechanism of anticancer activity (kinase inhibition and DNA damage). The study is also the first to report the application of a hybrid drug approach to switch TKIs from being efflux transporter substrates into non-substrates. TKIs cannot penetrate into the brain for treating metastases because of efflux transporters at the blood brain barrier. The hybrids were found to escape drug efflux and they accumulate more than the original TKI in the brain in BALB/c mice. Further development of the hybrid compounds is warranted.

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

    Standard systemic therapeutic agents used in acne include oral antimicrobials, isotretinoin, and hormonal agents. Appropriate patient selection is the key to decide when to use hormonal agents as first-line therapy as well as to achieve optimal results. Indications of hormonal therapy in acne in girls and women include proven ovarian or adrenal hyperandrogenism, recalcitrant acne, acne not responding to repeated courses of oral isotretinoin, acne tarda, polycystic ovary syndrome, or the presence of clinical signs of hyperandrogenism such as androgenic alopecia or the presence of the seborrhea, acne, hirsutism, alopecia syndrome. We describe the hormonal agents currently available for acne treatment, discuss their indications and contraindications, and address the question of whether they may be used as a first-line therapy in acne.

    The aim of this study was to describe first-line managers' experiences of alternative modes of funding elderly care in two communities in western Sweden. A growing elderly population demands alternative modes of funding elderly care for better outcomes for patients and better efficiency as it is publicly funded through taxation. The study comprised a total of eight semi-structured interviews with first-line managers working within elderly care. The interviews were analysed using manifest qualitative content analysis. Respect for the individuals was a main concern in the study. One category, quality improvement, and four subcategories freedom of choice, organisational structure, quality awareness and market forces effects were identified to describe first-line managers' experiences of the operation of elderly care. Quality improvement was an important factor to deal with when elderly care was operated in different organisational perspectives, either private or public. The first-line manager is a key person for developing a learning organisation that encourages both staff, clients and their relatives to improve the organisation. Moreover, person-centred care strengthens the client's role in the organisation, which is in line with the government's goal for the quality improvement of elderly care. However, further research is needed on how quality improvement could be developed when different caregivers operate in the same market in order to improve care from the elderly perspective. This study highlights alternative modes of funding elderly care. The economical perspectives should not dominate without taking care of quality improvement when the operation of elderly care is planned and implemented. Strategies such as a learning organisational structure built on person-centred care could create quality improvement in elderly care. © 2012 Blackwell Publishing Ltd.

    To compare virologic success between adult patients on tenofovir (TDF) and zidovudine (AZT)-containing first-line antiretroviral (ART) regimens in 10 rural clinics in Lesotho, Southern Africa. Multicentre cross-sectional study, patients ≥16 years, on first-line ART ≥6 months, receiving AZT/lamivudine (3TC) or TDF/3TC combined with efavirenz (EFV) or nevirapine (NVP). Patient characteristics and clinical/therapeutic history were collected on the day of blood draw for viral load (VL). Analysis was stratified for non-nucleoside reverse transcriptase inhibitor (EFV or NVP). A logistic regression model weighted for patients' baseline characteristics was used to assess the likelihood of virologic success (<80 copies/ml) in patients with TDF- as compared to AZT-backbones. In total 1539 patients were included in the analysis. Most were clinically and immunologically stable (clinical failure: 2.7% (AZT) and 2.8% (TDF); immunological failure: 4.6% (AZT) and 4.8% (TDF)). In EFV-based regimens (n = 1162), TDF was significantly associated with higher rates of virologic suppression than AZT (93.8% vs. 88.1%; weighted odds ratio: 2.15 (95% CI: 1.29-3.58; P = 0.003)). In NVP-based regimens, a similar trend was observed, but not significant (89.4% vs. 86.7%; 1.99 (0.83-4.75, P = 0.121)). These findings support the WHO recommendation to use TDF/3TC/EFV as first-line regimen. They do, however, not support the recommendation that patients who are clinically stable on AZT should continue on this first-line regimen. © 2015 John Wiley & Sons Ltd.

    In this review, we summarize the evidence for benzodiazepines and barbiturates as alcohol withdrawal treatment and outline a treatment guideline. A number of randomized controlled trials (RCTs) indicate that benzodiazepine treatment decreases alcohol withdrawal seizures and is safe....... For barbiturates, only a few RCTs have been undertaken, and barbiturates were not found to be superior to benzodiazepines. Consequently, we suggest that benzodiazepines should still be first-line treatment for alcohol withdrawal....

    2015-03-01

    The aim of this study was to explore how first-line nurse managers constructed the meaning of resilience and its relationship to work-life balance for nurses in Korea. Participants were 20 first-line nurse managers working in six university hospitals. Data were collected through in-depth interviews from December 2011 to August 2012, and analyzed using Strauss and Corbin's grounded theory method. Analysis revealed that participants perceived work-life balance and resilience to be shaped by dynamic, reflective processes. The features consisting resilience included "positive thinking", "flexibility", "assuming responsibility", and "separating work and life". This perception of resilience has the potential to facilitate a shift in focus from negative to positive experiences, from rigidity to flexibility, from task-centered to person-centered thinking, and from the organization to life. Recognizing the importance of work-life balance in producing and sustaining resilience in first-line nurse managers could increase retention in the Korean nursing workforce. Copyright © 2015.

    The management of achalasia remains controversial, with little consensus on the optimal patient treatment pathway. In our own esophageal unit, we offer pneumatic dilatation as the initial therapy in most patients as first-line therapy. In this study, we aimed to examine the safety and efficacy of our own approach to the management of patients with a diagnosis of achalasia, examining symptomatic outcomes, patient satisfaction, and need for further intervention, as well as examining patient factors associated with treatment failure. Sixty-seven consecutive patients underwent pneumatic dilatation as first-line therapy (53% male, mean age 46 years). All attended regular outpatient follow-up (mean 37, range 3-132 months). Twenty-five percent of patients required a second intervention because of symptom recurrence, at a median period of 4.5 months. Symptomatic outcomes were excellent or good in 80%. Significant predictors of treatment failure and poor symptom score included a younger age at the time of diagnosis and increased esophageal diameter on barium swallow. This study suggests that pneumatic dilatation is a safe and effective approach as first-line therapy in patients with newly diagnosed achalasia.

    Full Text Available Abstract Imatinib, a tyrosine kinase inhibitor (TKI of BCR-ABL, was the standard first-line therapy for chronic myeloid leukemia (CML for almost 10 years. Dasatinib and nilotinib, two newer drugs with higher potency than imatinib against BCR-ABL and activity against most imatinib-resistant BCR-ABL mutations, have each shown superior efficacy compared with imatinib for first-line treatment of chronic-phase CML in randomized phase 3 trials. With 14 months follow-up time, available data suggest no obvious differences in efficacy between dasatinib and nilotinib. Compared with imatinib, dasatinib is associated with higher rates of pleural effusion and thrombocytopenia, but lower rates of edema, gastrointestinal AEs, musculoskeletal AEs, and rash. Nilotinib is associated with higher rates of dermatologic toxicity, headache, and biochemical abnormalities associated with hepatic and pancreatic toxicity compared with imatinib, but lower rates of edema, gastrointestinal AEs, muscle spasm, and neutropenia. Several studies have shown that poor adherence to imatinib detrimentally affects responses and should be considered in patients with a suboptimal response. The different dosing requirements of dasatinib (once daily with or without food and nilotinib (twice daily with fasting may be an additional factor in selecting frontline agents. This review compares and contrasts the three FDA approved first line TKI agents.

    Despite the initially high response rate to standard front-line debulking surgery followed by platinum-based chemotherapy, the relapse rate in ovarian cancer is high and many patients will recur within 6 months of completing platinum based treatment. These patients may still require further chemotherapy despite being considered "platinum resistant". In this setting, response rates to conventionally scheduled second line platinum and non-platinum agents is low, ranging between 5% and 15%. There is an emerging body of evidence that in this scenario, chemotherapeutic activity can be enhanced using unconventionally scheduled "dose-dense" platinum and non-platinum based regimens with improved response rates of up to 65%. Randomised studies to evaluate the impact of this approach on survival in recurrent, platinum resistant disease are urgently required to confirm the promising phase II findings if there is to be a change in the standard of care of patients with platinum resistant disease. In this review we discuss the evolving strategies to overcome resistance in patients with platinum resistant ovarian cancer with a particular focus on alterations in dose schedule as a means of reversing platinum resistance.

    The backbone of current cytotoxic treatment of metastatic colorectal cancer (mCRC) consists of a fluoropyrimidine together with either oxaliplatin (XELOX/FOLFOX) or irinotecan (XELIRI/FOLFIRI). With an overall objective response rate of approximately 50% for either treatment combination, a major unsolved problem is that no predictors of response to these treatments are available. To address this issue, we profiled 742 microRNAs in laser-capture microdissected cancer cells from responding and non-responding patients receiving XELOX/FOLFOX as first-line treatment for mCRC, and identified, among others, high expression of miR-625-3p, miR-181b and miR-27b to be associated with poor clinical response. In a validation cohort of 94 mCRC patients treated first-line with XELOX, high expression of miR-625-3p was confirmed to be associated with poor response (OR = 6.25, 95%CI [1.8; 21.0]). Independent analyses showed that miR-625-3p was not dysregulated between normal and cancer samples, nor was its expression associated with recurrence of stage II or III disease, indicating that miR-625-3p solely is a response marker. Finally, we also found that these miRNAs were up-regulated in oxaliplatin resistant HCT116/oxPt (miR-625-3p, miR-181b and miR-27b) and LoVo/oxPt (miR-181b) colon cancer cell lines as compared with their isogenic parental cells. Altogether, our results suggest an association between miR-625-3p and response to first-line oxaliplatin based chemotherapy of mCRC.

    Background No biomarker is available to predict prognosis of patients with advanced ovarian cancer (AOC) and guide the choice of chemotherapy. We performed a prospective-retrospective biomarker study within the MITO2 trial on the treatment of AOC. Patients and methods: MITO2 is a randomised multicentre phase 3 trial conducted with 820 AOC patients assigned carboplatin/paclitaxel (carboplatin: AUC5, paclitaxel: 175 mg/m², every 3 weeks for 6 cycles) or carboplatin/PLD-pegylated liposomal doxorubicin (carboplatin: AUC5, PLD: 30 mg/m², every 3 weeks for 6 cycles) as first line treatment. Sixteen biomarkers (pathways of adhesion/invasion, apoptosis, transcription regulation, metabolism, and DNA repair) were studied in 229 patients, in a tissue microarray. Progression-free and overall survival were analysed with multivariable Cox model. Results After 72 months median follow-up, 594 progressions and 426 deaths were reported; there was no significant difference between the two arms in the whole trial. No biomarker had significant prognostic value. Statistically significant interactions with treatment were found for DNA-dependent protein kinase (DNA-PK) and phosphorylated acetyl-coenzymeA carboxylase (pACC), both predicting worse outcome for patients receiving carboplatin/paclitaxel. Conclusion These data show that in presence of DNA-PK or pACC overexpression, carboplatin/paclitaxel might be less effective than carboplatin/PLD as first line treatment of ovarian cancer patients. Further validation of these findings is warranted. PMID:27655643

    To evaluate the cost-effectiveness of bendamustine compared with chlorambucil as first-line treatment for patients with chronic lymphocytic leukemia who would be considered unsuitable for treatment with fludarabine combination chemotherapy regimens. A semi-Markov approach was used to estimate time in each health state. The model was parameterized primarily by using data from a phase III randomized, open-label trial comparing bendamustine with chlorambucil. It captured the increased progression-free survival and improved response rates with bendamustine, and the cost and quality of life impacts of postprogression treatments. The analysis was conducted from the perspective of the National Health Service in England and Wales. A lifetime (35-year) time horizon was used. Deterministic sensitivity analyses, probabilistic sensitivity analyses, and subgroup analyses in older patients and patients with poor performance status were carried out. The estimated incremental cost-effectiveness ratio was £ 11,960 per quality-adjusted life-year. None of the deterministic sensitivity analyses increased the incremental cost-effectiveness ratio by more than £ 2000. Subgroup analyses showed that bendamustine remained cost-effective across different patient groups. Probabilistic sensitivity analysis showed that at the £ 20,000 threshold, bendamustine has a 90% probability of being cost-effective. Bendamustine represents good value for first-line treatment of patients with chronic lymphocytic leukemia who are unsuitable for treatment with fludarabine combination chemotherapy. The incremental cost-effectiveness ratio is below the thresholds commonly applied in England and Wales (£ 20,000-£ 30,000 per quality-adjusted life-year).

    The randomised, controlled OSHO#39 study showed promising results using first-line mitoxantrone, chlorambucil and prednisolone (MCP) chemotherapy plus rituximab in patients with advanced symptomatic follicular lymphoma (FL) in need of therapy. The aim of this long-term follow-up was to investigate whether clinical benefits are maintained after up to 9 years of observation. Following the 4-year follow-up of OSHO#39, 77 FL patients who received rituximab plus MCP (R-MCP) and 52 patients who received MCP (129 patients alive and not previously censored in total) were followed for 5 additional years in this prospective, non-interventional, observational study. For the efficacy analysis, data were jointly analysed with OSHO#39 data (FL intention-to-treat population: 105 patients R-MCP, 96 MCP). Patients not included in the 5-year follow-up were censored. For surviving patients, median follow-up was 102 months (R-MCP) and 87 months (MCP). Although median overall survival (OS) was not yet reached, OS was longer for patients with R-MCP compared with MCP (p = 0.0057), with 8-year-survival rates of 76.1 versus 55.9%. Further time-to-event data were substantially longer for the R-MCP group than for MCP alone: median progression-free survival (PFS) was 93.4 versus 34.9 months, and median event-free survival (EFS) 89.6 versus 26.5 months. Unplanned subanalyses of patients with and without interferon maintenance showed improved PFS and EFS without an impact on OS. The addition of rituximab to first-line MCP chemotherapy improves clinical outcomes in advanced FL patients and translates into long-term OS benefits. R-MCP remains a promising standard option for this patient group.

    Primary HIV drug resistance has been associated with poor treatment outcome of first-line highly active antiretroviral therapy (HAART) in several trials. The aim of the study was to assess the efficacy of first-line HAART guided by resistance testing. In a prospective multicenter study in the state of Nordrhein-Westfalen, Germany, chronically HIV-infected patients underwent genotypic resistance testing and were monitored for 48 weeks after initiation of HAART. Primary drug resistance was found in 30 of 269 patients entering the study between January 2001 and December 2003 [11.2%; 95% confidence interval, 7.4-14.9]. In intent-to-treat analysis, the proportion of patients with viral load below 50 copies/mL after 24 and 48 weeks was 70.0% and 66.7%, respectively, in patients with resistance and 74.1% and 73.6%, respectively, in patients without (P = 0.66 and 0.51). In on-treatment analysis, the proportions were 80.8% and 83.3%, respectively, in patients with resistance and 81.9% and 85.0%, respectively, in patients without (P= 0.79 and 0.77). These results were also valid considering a detection limit of 400 copies/mL. The prevalence of primary drug resistance was 11.2% in chronically HIV-infected patients. HAART guided by resistance testing had similar efficacy in patients with primary drug resistance as compared with patients with wild-type virus. Based on these facts, resistance-adapted first-line HAART is suggested as routine practice.

    Although uncommon in treatment-naive patients with chronic lymphocytic leukemia, deletion 17p is a high-risk disease characteristic. We analyzed and reported outcomes for 63 patients with deletion 17p chronic lymphocytic leukemia who received first-line therapy at our institution; at time of first treatment, 81% had unmutated immunoglobulin heavy chain variable gene and 58% had complex karyotype. Forty-nine patients (76%) received first-line fludarabine, cyclophosphamide, rituximab-based therapy, 6 (11%) received rituximab-based and 8 (13%) received lenalidomide-based treatment. Overall, the complete plus nodular partial remission rate was 33%; on multivariable model, higher complete plus nodular partial remission rate was observed in patients with less than 50% cells positive for deletion 17p, and a higher probability of achieving at least a partial remission was observed with fludarabine, cyclophosphamide, rituximab-based treatment. After a median follow up of 33 months (range 1-89 months), the estimated median progression-free survival was 14 months (95% confidence interval 10-18) and estimated median overall survival was 63 months (95% confidence interval 43-83). In multivariable analysis, factors independently associated with longer progression-free survival were response to treatment and absence of complex karyotype. Achievement of complete plus nodular partial remission rate and mutated immunoglobulin heavy chain variable gene were independently associated with longer overall survival in multivariable model. Complex karyotype was associated with increased risk for Richter's transformation. New first-line strategies and agents must aim at both improving response and maintaining remission in patients with deletion 17p, particularly in the presence of complex karyotype.

    To investigate the factors that affect the choice of 5-fluorouracil (5-FU) or its oral alternative, capecitabine, as first-line treatment in patients with colorectal cancer (CRC). Patients treated with 5-FU or capecitabine for CRC between January 1, 2011 and December 31, 2013 in a teaching hospital in the Sydney metropolitan area, Australia were identified using the hospital's database MOSAIQ(®). The electronic medical record of each patient was manually reviewed to extract factors potentially affecting treatment choice. Logistic regression was used to assess which patient and/or treatment factors could explain the choice between 5-FU or capecitabine. Where it was available in the medical correspondence, the explicit reason for the choice made was extracted. 170 CRC patients were included; 119 on 5-FU, and 51 on capecitabine. The odds of receiving capecitabine as a first-line treatment were positively associated with giving patients a choice in the decision (OR = 17.51, 95% CI: 5.37-57.08). Qualitative data suggest treatment choices were motivated by convenience (oral administration) and tolerability. Time from diagnosis to treatment commencement (OR = 1.02 per month, 95% CI 1.00-1.04) was also found to be positively associated with the choice of capecitabine. The odds of being treated with capecitabine were lower for patients who lived further from the treating hospital (OR = 0.22, 95% CI 0.05-0.94). This study suggests that patient choice, favoring oral capecitabine over i.v. 5-FU, was a key factor influencing first-line treatment for CRC in this cohort. To respect their autonomy, patients should be involved in the clinical decision making process.

    Coccidioidomycosis is an infection caused by inhalation of the Coccidioides fungus. Most infections remain subclinical or are confined to the pulmonary system. Disseminated disease is rare. Traditionally, a combination of imaging modalities has been used to determine disease extent. We suggest (18)F-FDG PET/CT as a single first-line imaging examination to assess disease extent. We present a case of disseminated coccidioidomycosis to the lung, mediastinum, soft tissues, and skeletal system. To our knowledge, no prior case reports demonstrate such widespread disease using PET/CT. © 2016 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

    Full Text Available Hemangiomas are the most common tumors of infancy. Most of them require no treatment, but treatment is needed if dramatic aesthetic, and/or functional impairment as visual or airway obstruction or ulceration arises. We reported a 6-month-old infant presented with a 6-week history of a rapidly growing cutaneus hemangioma on the right eyelid and caused visual impairment. The patient was successfully treated with the use of oral propranolol therapy. We suggest that propranolol can be considered as a first line treatment in a patient with infantil hemangioma.

    Full Text Available The tools for managing retinoblastoma have been increasing in the past decade. While globe-salvage still relies heavily on intravenous chemotherapy, tumors in advanced stage that failed chemotherapy are now referred for intra-arterial chemotherapy (IAC to avoid enucleation. However, IAC still has many obstacles to overcome. We present an update on the indications, complications, limitations, success, and technical aspects of IAC. Given its safety and high efficacy, it is expected that IAC will replace conventional strategies and will become a first-line option even for tumors that are amenable for other strategies.

    To compare efficacy of pemetrexed versus pemetrexed plus carboplatin in pretreated patients with advanced non-small-cell lung cancer (NSCLC). Patients with advanced NSCLC, in progression during or after first-line platinum-based chemotherapy, were randomly assigned to receive pemetrexed (arm A) or pemetrexed plus carboplatin (arm B). Primary end point was progression-free survival (PFS). A preplanned pooled analysis of the results of this study with those of the NVALT7 study was carried out to assess the impact of carboplatin added to pemetrexed in terms of overall survival (OS). From July 2007 to October 2009, 239 patients (arm A, n = 120; arm B, n = 119) were enrolled. Median PFS was 3.6 months for arm A versus 3.5 months for arm B (hazard ratio [HR], 1.05; 95% CI, 0.81 to 1.36; P = .706). No statistically significant differences in response rate, OS, or toxicity were observed. A total of 479 patients were included in the pooled analysis. OS was not improved by the addition of carboplatin to pemetrexed (HR, 90; 95% CI, 0.74 to 1.10; P = .316; P heterogeneity = .495). In the subgroup analyses, the addition of carboplatin to pemetrexed in patients with squamous tumors led to a statistically significant improvement in OS from 5.4 to 9 months (adjusted HR, 0.58; 95% CI, 0.37 to 0.91; P interaction test = .039). Second-line treatment of advanced NSCLC with pemetrexed plus carboplatin does not improve survival outcomes as compared with single-agent pemetrexed. The benefit observed with carboplatin addition in squamous tumors may warrant further investigation.

In the CAM307 study alemtuzumab was tested and finally approved as a first-line single agent, even though the hurdle with chlorambucil as the contender was not set very high. Within clinical trials, the drug demonstrated an excellent ability to eliminate minimal residual disease in blood and bone marrow, which has been correlated with a corresponding survival advantage in patients. However, in the maintenance setting, infectious complications due to severe T cell suppression have been highlighted and do not allow clinicans to use alemtuzumab outside of clinical trials. This review discusses potential therapeutic niches and future applications of alemtuzumab with a focus on CLL front-line treatment.Keywords: CLL, alemtuzumab, Campath, front-line, first-line treatment

    Full Text Available Abstract Background The aim of the study was to determine the most common pharmacological strategies used in the management of major depressive disorder (MDD after an inadequate response to first-line antidepressant treatment in clinical practice. Methods Multicenter, non-interventional study in adult outpatients with a DSM-IV-TR diagnosis of MDD and inadequate response to first-line antidepressant medication. Multiple logistic regression analyses were performed to identify independent factors associated with the adoption of a specific second-line strategy. Results A total of 273 patients were analyzed (mean age: 46.8 years, 67.8% female. Baseline mean Montgomery-Asberg Depression Rating Scale total score was 32.1 (95%CI 31.2-32.9. The most common strategies were: switching antidepressant medication (39.6%, augmentation (18.8%, and combination therapy (17.9%. Atypical antipsychotic drugs were the most commonly used agent for augmenting antidepressant effect. The presence of psychotic symptoms and the number of previous major depressive episodes were associated with the adoption of augmenting strategy (OR = 3.2 and 1.2, respectively. Conclusion The switch to another antidepressant agent was the most common second-line therapeutic approach. Psychiatrists chose augmentation based on a worse patients’ clinical profile (number of previous episodes and presence of psychotic symptoms.

    Medulloblastoma is an aggressive primitive neuroectodermal tumor of the cerebellum that is rare in adults. Medulloblastomas fall into 4 prognostically significant molecular subgroups that are best defined by experimental gene expression profiles: the WNT pathway, sonic hedgehog (SHH) pathway, and subgroups 3 and 4 (non-SHH/WNT). Medulloblastoma of adults belong primarily to the SHH category. Vismodegib, an SHH-pathway inhibitor FDA-approved in 2012 for treatment of basal cell carcinoma, has been used successfully in the setting of chemorefractory medulloblastoma, but not as a first-line therapy. In this report, we describe a sustained response of an unresectable multifocal form of adult medulloblastoma to vismodegib. Molecular analysis in this case revealed mutations in TP53 and a cytogenetic abnormality, i17q, that is prevalent and most often associated with subgroup 4 rather than the SHH-activated form of medulloblastoma. Our findings indicate that vismodegib may also block alternate, non-canonical forms of downstream SHH pathway activation. These findings provide strong impetus for further investigation of vismodegib in clinical trials in the first-line setting for pediatric and adult forms of medulloblastoma.

  17. Energy basis of recognition of base pair for platinum-based antitumour drug ZD0473 and cisplatin

    2008-01-01

    Platinum-based antitumour drug ZD0473 was designed to reduce the cisplatin resistance to the tumor cells. In this paper, the mixed method of molecular mechanics and quantum chemistry, HF/lanl2dz// MM/uff and B3LYP/lanl2dz//6-31G*, are used to investigate the differences between four types of GG, 3′AG5′, 3′GA5′, and AA complexes, which are formed from four discrete DNA fragments recognized by ZD0473 and cisplatin. The results show that the binding interaction of both ZD0473 and cisplatin drugs with the GG base pair is much stronger than with other base pairs, namely the recognition capability of such drugs to the GG base pair is more considerable. Moreover, the interaction of four complexes of ZD0473 with DNA fragments is stronger than that of cisplatin with corresponding DNA fragments, which indicates the stronger binding capability of ZD0473 with DNA fragments and high antitumour activity of ZD0473. The main reason for easier forming of 3′GA5′ complex than the 3′AG5′ one is that the drug molecule prefers to bind with a single G base to form a monoligand compound firstly; then the con- figuration transformation from such monoligand compound to the bi-ligand one is limited.

    through passive transport within the tumor. Recent advances have enhanced the diffusion of pharmaceuticals through active transport by using pharmaceuticals designed to target the genome of tumors. In the present study, five patients with non-small cell lung cancer epidermal growth factor receptor (EGFR negative stage IIIa–IV International Union Against Cancer 7 (UICC-7, and with Eastern Cooperative Oncology Group (ECOG 2 scores were administered platinum-based doublet chemotherapy using combined intratumoral-regional and intravenous route of administration. Cisplatin analogues were injected at 0.5%–1% concentration within the tumor lesion and proven malignant lymph nodes according to pretreatment histological/cytological results and the concentration of systemic infusion was decreased to 70% of a standard protocol. This combined intravenous plus intratumoral-regional chemotherapy is used as a first line therapy on this short series of patients. To the best of our knowledge this is the first report of direct treatment of involved lymph nodes with cisplatin by endobronchial ultrasound drug delivery with a needle without any adverse effects. The initial overall survival and local response are suggestive of a better efficacy compared to established doublet cisplatin–based systemic chemotherapy in (higher standard concentrations alone according to the UICC 7 database expected survival. An extensive search of the literature was performed to gather information of previously published literature of intratumoral chemo-drug administration and formulation for this treatment modality. Our study shows a favorable local response, more than a 50% reduction, for a massive tumor mass after administration of five sessions of intratumoral chemotherapy plus two cycles of low-dose intravenous chemotherapy according to our protocol. These encouraging results (even in very sick ECOG 2 patients with central obstructive non-small cell lung cancer having a worse prognosis and quality of

    Full Text Available Chemotherapy is the first line treatment in management of many cancers, both for cure and palliation; hence it’s crucial to minimize the unpleasant side effects of chemotherapy to increase tolerability to chemotherapy. Most of the conventional anti cancer drugs are emetogenic. Patients receiving chemotherapy experience different degrees of nausea and vomiting depending on the emetogenic potential of the anti cancer drugs given and the patient characteristics. With a better understanding of the pathophysiology, distinct phases of chemotherapy-induced nausea and vomiting (CINV i.e., acute emesis, delayed emesis and anticipatory emesis have been identified. Identification of various mediators has led to the development of different drugs acting through different mechanisms which are useful in the prevention and treatment of CINV. Serotonin receptor three (5-HT3 antagonists, corticosteroids and neurokinin type one receptor (NK-1 antagonists are of proven usefulness and have wide therapeutic indexes in the prevention of CINV. Other drugs like dopamine receptor antagonists & benzodiazepines are not routinely used because of their narrow therapeutic index. Practice guidelines for prevention of CINV will not only improve patient’s tolerability to chemotherapy & wellbeing, but also decrease hospital stay and overall cost of treatment of the patient.

    Full Text Available Genetic variants have been shown to affect length of survival in cancer patients. This study explored the association between lung cancer susceptibility loci tagged by single-nucleotide polymorphisms (SNPs identified in the genome-wide association studies and length of survival in small-cell lung cancer (SCLC. Eighteen SNPs were genotyped among 874 SCLC patients and Cox proportional hazards regression was used to examine the effects of genotype on survival length under an additive model with age, sex, smoking status and clinical stage as covariates. We identified 3 loci, 20q13.2 (rs4809957G >A, 22q12.2 (rs36600C >T and 5p15.33 (rs401681C >T, significantly associated with the survival time of SCLC patients. The adjusted hazard ratio (HR for patients with the rs4809957 GA or AA genotype was 0.80 (95% CI, 0.66-0.96; P = 0.0187 and 0.73 (95% CI, 0.55-0.96; P = 0.0263 compared with the GG genotype. Using the dominant model, the adjusted HR for patients carrying at least one T allele at rs36600 or rs401681 was 0.78 (95% CI, 0.63-0.96; P = 0.0199 and 1.29 (95% CI, 1.08-1.55; P = 0.0047, respectively, compared with the CC genotype. Stratification analyses showed that the significant associations of these 3 loci were only seen in smokers and male patients. The rs4809957 SNP was only significantly associated with length of survival of patients with extensive-stage but not limited-stage tumor. These results suggest that some of the lung cancer susceptibility loci might also affect the prognosis of SCLC.

    2014-05-01

    A general method for tracking morphological surface changes on a nanometer scale with scanning electron microscopy (SEM) is introduced. We exemplify the usefulness of the method by showing consecutive SEM images of an identical location before and after the electrochemical and thermal treatments of platinum-based nanoparticles deposited on a high surface area carbon. Observations reveal an insight into platinum based catalyst degradation occurring during potential cycling treatment. The presence of chloride clearly increases the rate of degradation. At these conditions the dominant degradation mechanism seems to be the platinum dissolution with some subsequent redeposition on the top of the catalyst film. By contrast, at the temperature of 60°C, under potentiostatic conditions some carbon corrosion and particle aggregation was observed. Temperature treatment simulating the annealing step of the synthesis reveals sintering of small platinum based composite aggregates into uniform spherical particles. The method provides a direct proof of induced surface phenomena occurring on a chosen location without the usual statistical uncertainty in usual, random SEM observations across relatively large surface areas.

    Current evidence suggests that epoetin alpha administration is well tolerated and effective in the management of anemia of cancer and cancer chemotherapy. An open-label, multinational, non-comparative study was conducted in 215 cancer patients with anemia secondary to chemotherapy with platinum- or non-platinum-based combinations. Epoetin alpha was administered s.c. (150 IU/kg three times/week) for a planned period of 16 weeks. The response rate of epoetin alpha, defined as an increase in hemoglobin level of 2 g/dl or more from baseline, was 67%. The rate of response was not related to the chemotherapy regimen administered (platinum or non-platinum based). The percentage of patients transfused and the transfusion rate during epoetin alpha treatment were reduced. Transfusional need was eliminated in 64 (75%) of the 85 patients transfused before the study start, after 1 month of therapy. Quality of life, assessed using a visual analog scale, improved markedly in patients who experienced a hematological response. These patients also experienced a statistically significant (p performance score. These findings indicate that epoetin alpha is a well tolerated and effective agent which increases hemoglobin concentration and reduces transfusion requirements in anemic cancer patients receiving chemotherapy.

    2015-12-01

    Leaks are the most frequent early postoperative complication in the two most popular bariatric procedures, Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy. Multimodal therapy based on self-expandable stent insertion 'to cover' the defect is the most widely documented technique to date with a reported success rate >80%. Additional experimental techniques 'to close' the defect or 'to drain' the paradigestive cavity have been reported with encouraging results. The role of endoscopy in early postoperative bleeding is limited to management of bleeds arising from fresh sutures and the diagnosis of chronic sources of bleeding such as marginal ulcer after RYGB. Post-RYGB stricture is a more delayed complication than leaks and the role of endoscopic dilation as a first-line treatment in this indication is well documented. Ring and band placement are outdated procedures for obesity treatment, but might still be an indication for endoscopic removal, a technique which does not compromise further surgery, if needed.

    Pathogenic strains of Acanthamoeba genus are the causative agents of fatal granulomatous amoebic encephalitis and a serious sight-threatening infection of the eye known as Acanthamoeba keratitis. In a previous study, Acanthamoeba strains were isolated from nasal swabs collected from healthy individuals in Peru. In the present study, the pathogenic potential of the isolated strains was established based on temperature and osmotolerance assays as well as the secretion rate of extracellular proteases. Based on these experiments, four strains that showed the highest pathogenic potential were selected for sensitivity assays against two molecules (voriconazole and chlorhexidine) which are currently used for the treatment of Acanthamoeba infections. After performing sensitivity and activity assays, it was found that both drugs were active against the tested strains. However, voriconazole showed higher activity against the studied strains compared to chlorhexidine. Therefore, voriconazole should be established as a first-line treatment against Acanthamoeba infections at least in the studied region of Peru.

    A recent Intercontinental Cooperative ITP Study Group (ICIS) meeting in September 2015 focused on immunomodulation across the spectrum of autoimmune conditions. It became clear to the attendees that in this wide range of conditions, there is a subset of patients that remain highly refractory to first line therapy. Therapeutic approaches to these patients vary greatly and while many different immunomodulatory agents have been investigated, few have seen universal success. We outline here the landscape of immunomodulation therapy for refractory patients across a variety of autoimmune conditions in order to highlight the variety of agents that have been studied, the lack of overall consensus about management, and the need for ongoing research in this area.

    Approximately one-fourth of the estimated 10,000 HIV-infected children in Burkina Faso are undergoing antiretroviral (ARV) therapy. At the Charles de Gaulle Pediatric Hospital Center in Ouagadougou, Burkina Faso, Support for ARV therapy began in July 2003 and a total of 250 children were undergoing treatment in late 2007. The purpose of this retrospective case-control study conducted over a period of 54 months from July 2003 to December 2007 was to investigate cases involving failure of first-line ARV therapy in particular with regard to cause. All patients (n = 32) showing poor virological, immunological, and/or clinical response to ARV therapy were considered as failures and thus included in the case group. The control group (n = 160) consisted of patients with good responses to treatment. Cases and controls were compared using the Chi-square test and odds ratio (OR) technique with a confidence interval at 95%. The failure rate was 12.8%. Failure was significantly correlated with low socioeconomic level (OR = 3), orphan status (OR = 4), age over 10 years (OR = 5), male gender (OR = 3), baseline viral load > or = 1,000,000 copies/mL (OR = 9), and poor compliance (OR = 37). Mortality in children who failed to respond to first-line ARV therapy was 25% due to the unavailability of a national second-line ARV therapy program. This study underlines the need for patient education to promote compliance and for creation of reference centers to prescribe ARV therapy to HIV-infected children including second-line ARV and genotyping.

    Concentrations of the cytotoxic platinum-based anticancer drugs, as total Pt, have been measured over a three week period in one of the main drains and in the effluent of the oncology ward of a major UK hospital (Derriford, Plymouth). Concentrations of Pt were highly variable in both discharges, and ranged from about 0.02 to 140 μg L(-1) in the oncology effluent and from about 0.03 to 100 μg L(-1) in the main drain. A comparison of drug administration figures over the study period with an estimate of the quantity of Pt discharged through the drains suggests that about 22% of total Pt is emitted to the environment from the hospital with the remainder being discharged by treated patients in the wider community. Administration figures for the three Pt-based drugs used in the hospital (cisplatin, carboplatin and oxaliplatin) coupled with published measurements on the removal of the drugs by conventional sewage treatment allowed the concentrations of Pt arising from each drug to be predicted in recipient surface waters as a function of water flow rate. For conditions representative of the region under study, concentrations of total Pt between a few tens and in excess of 100 pg L(-1) are predicted, with the principal form of the metal occurring as carboplatin and its metabolites. Although predicted concentrations are below EMEA guidelines warranting further risk assessment, the presence of substances in surface waters that are potentially carcinogenic, mutagenic and teratogenic and yet whose environmental effects are not understood is cause for concern.

    2017-04-15

    This thesis presents an integrated study of nanocatalysts for heterogenous catalytic and electrochemical processes using pure ruthenium (Ru) with mixed-phase and platinum-based nanomaterials synthesized by continuous-flow chemistry. There are three major challenges to the application of nanomaterials in heterogenous catalytic reactions and electrocatalytic processes in acidic solution. These challenges are the following: (i) controlling the size, shape and crystallography of nanoparticles to give the best catalytic properties, (ii) scaling these nanoparticles up to a commercial quantity (kg per day) and (iii) making stable nanoparticles that can be used catalytically without degrading in acidic electrolytes. Some crucial limitations of these nanostructured materials in energy conversion and storage applications were overcome by continuous-flow chemistry. By using a continuous-flow reactor, the creation of scalable nanoparticle systems was achieved and their functionality was modified to control the nanoparticles’ physical and chemical characteristics. The nanoparticles were also tested for long-term stability, to make sure these nanoparticles were feasible under realistic working conditions. These nanoparticles are (1) shape- and crystallography-controlled ruthenium (Ru) nanoparticles, (2) size-controlled platinum-metal (Pt-M= nickel (Ni) & copper (Cu)) nanooctahedra (while maintaining morphology) and (3) core-shell platinum@ruthenium (Pt@Ru) nanoparticles where an ultrathin ruthenium shell was templated onto the platinum core. Thus, a complete experimental validation of the formation of a scalable amount of these nanoparticles and their catalytic activity and stability towards the oxygen evolution reaction (OER) in acid medium, hydrolysis of ammonia borane (AB) along with plausible explanations were provided.

    Platinum-based neoadjuvant therapy is the standard treatment for esophageal cancer (EC). At present, no reliable response markers exist, and patient therapeutic outcome is variable and very often unpredictable. The aim of this study was to understand the contribution of host constitutive DNA polymorphisms in discriminating between responder and nonresponder patients. DNA collected from 120 EC patients treated with platinum-based neoadjuvant chemotherapy was analyzed using drug metabolism enzymes and transporters (DMET) array platform that interrogates polymorphisms in 225 genes of drug metabolism and disposition. Four gene variants of DNA repair machinery, 2 in ERCC1 (rs11615; rs3212986), and 2 in XPD (rs1799793; rs13181) were also studied. Association analysis was performed with pTest software and corrected by permutation test. Predictive models of response were created using the receiver-operating characteristics curve approach and adjusted by the bootstrap procedure. Sixteen single nucleotide polymorphisms (SNPs) of the DMET array resulted significantly associated with either good or poor response; no association was found for the 4 variants mapping in DNA repair genes. The predictive power of 5 DMET SNPs mapping in ABCC2, ABCC3, CYP2A6, PPARG, and SLC7A8 genes was greater than that of clinical factors alone (area under the curve [AUC] = 0.74 vs 0.62). Interestingly, their combination with the clinical variables significantly increased the predictivity of the model (AUC = 0.78 vs 0.62, P = 0.0016). In conclusion, we identified a genetic signature of response to platinum-based neoadjuvant chemotherapy in EC patients. Our results also disclose the potential benefit of combining genetic and clinical variables for personalized EC management.

    Full Text Available AIM: The role of Sirtuin 1 (SIRT 1 in carcinogenesis is controversial. This study was to explore the association between the SIRT1 expression and the clinical characteristics, the responsiveness to chemotherapy and prognosis in Non-small cell lung cancer (NSCLC. METHODS: We enrolled 295 patients with inoperable advanced stage of NSCLC, namely, stage III (A+B and IV NSCLC. All patients had received platinum-based chemotherapy after diagnosis and the chemotherapy response were evaluated. All patients were followed up for overall survival (OS and progression free survival (PFS. In vitro, H292 cells were tranfected with SIRT1 small interfering RNA (siRNA. The cell biological behaviors and chemosensitivity to cisplatin treatment were studied. The in vivo tumorgenesis and metastasis assays were performed in nude mice. RESULTS: We found that the SIRT1 expressions were significantly associated with the tumor stage, tumor size and differentiation status. Patients with high SIRT 1 expressions had a significantly higher chance to be resistant to chemotherapy than those with low SIRT 1 expression. Patients with high expression of SIRT1 had significantly shorter OS and DFS than those with low expression. Cox analyses confirmed that the SIRT 1 expression was a strong predictor for a poor OS and PFS in NSCLC patients underwent Platinum-based chemotherapy. In vitro studies revealed that the reduced expression SIRT 1 by siRNA technique significantly inhibited cell proliferation, migration and invasion. More importantly, SIRT1 si-RNA significantly enhanced the chemosensitivity of H292 cells to cisplatin treatment. The in vivo tumorgenesis and metastasis assays showed that SIRT1 knockdown dramatically reduced the tumor volume and the metastatic ability in nude mice. CONCLUSION: Collectively, our data suggest that the SIRT1 expression may be a molecular marker associated with the NSLCLC clinical features, treatment responsiveness and prognosis of advanced NSCLC.

    Gastric cancer is the fifth most common cancer and third leading cause of cancer-related deaths worldwide. Complete resection of the whole tumor remains the only approach to treat this malignant disease. Since gastric cancer is usually asymptomatic in its early stages, many people are diagnosed at an advanced stage when the tumor is inoperable. In addition, because other conventional treatments (radiotherapy and chemotherapy) have only modest efficacy for those with advanced/metastatic gastric cancer, the prognosis in such cases is poor. Recently, trials have provided some promising results regarding molecular-targeted therapy, raising the possibility that the development of these agents could be a fruitful approach. However, the benefit of molecular-targeted therapy for advanced gastric cancer remains inconclusive. To evaluate the efficacy and safety of molecular-targeted therapy , either alone or in combination with chemotherapy, in people with advanced gastric cancer. We searched the following databases (from inception to December 2015): the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and CINAHL. In addition, we searched the reference lists of included trials and contacted experts in the field. We searched for randomized controlled trials (RCTs) in adults (aged 18 years or older) with histologically-confirmed advanced adenocarcinoma of the stomach/gastro-esophageal junction. Trials of participants with esophageal adenocarcinoma were also considered to be eligible. The eligible trials should aim to evaluate the effects of molecular-targeted agents on participants' prognosis. Two review authors independently performed selection of eligible trials, assessment of trial quality, and data extraction. We used methods of survival analysis and expressed the intervention effect as a hazard ratio (HR) when pooling time-to-event data, and calculated the odds ratio (OR) for dichotomous data and mean differences (MDs) for continuous data, with

    Full Text Available Abstract Background Medicines to control hypertension, a leading cause of morbidity and mortality, are a major component of health expenditures in the Philippines. This study aims to review economic studies for first line anti-hypertensive medical treatment without co-morbidities; and discuss practical, informational and policy implications on the use of economic evaluation in the Philippines. Methods A systematic literature review was performed using the following databases: MEDLINE, EMBASE, BIOSIS, PubMed, The Cochrane Library, Health Economics Evaluations Database (HEED and the Centre for Reviews and Dissemination – NHS NICE. Six existing economic analytical frameworks were reviewed and one framework for critical appraisal was developed. Results Out of 1336 searched articles, 12 fulfilled the inclusion criteria. The studies were summarized according to their background characteristics (year, journal, intervention and comparators, objective/study question, target audience, economic study type, study population, setting and country and source of funding/conflict of interest and technical characteristics (perspective, time horizon, methodology/modeling, search strategy for parameters, costs, effectiveness measures, discounting, assumptions and biases, results, cost-effectiveness ratio, endpoints, sensitivity analysis, generalizability, strengths and limitations, conclusions, implications and feasibility and recommendations. The studies represented different countries, perspectives and stakeholders. Conclusions Diuretics were the most cost-effective drug class for first-line treatment of hypertension without co-morbidities. Although the Philippine Health Insurance Corporation may apply the recommendations given in previous studies (i.e. to subsidize diuretics, ACE inhibitors and calcium channel blockers, it is uncertain how much public funding is justified. There is an information gap on clinical data (transition probabilities, relative risks

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

    To assess the prevalence of acquired drug resistance in HIV-1-infected patients living in Monrovia, Liberia, who had clinical and/or immunological failure of first-line ART according to WHO criteria. Patients receiving ART for >1 year with clinical and/or immunological failure were included. Sequencing of protease and reverse transcriptase regions was performed using Agence Nationale de Recherche sur le SIDA et les hépatites virales (ANRS) procedures and sequences were interpreted using the ANRS resistance algorithm. Ninety patients were enrolled. They had been receiving ART for a median time of 42 months and half were receiving zidovudine/lamivudine/nevirapine. Seventy-five per cent of patients were infected with CRF02_AG. Twenty-seven per cent of patients displayed a plasma viral load viruses with PI RAMs. Regarding NRTI drug resistance, 29%, 38%, 63%, 29% and 25% of patients had viruses resistant to zidovudine, stavudine, lamivudine/emtricitabine, abacavir and tenofovir, respectively. Regarding the NNRTI drug class, 56%, 65%, 33% and 42% of patients had viruses resistant to efavirenz, nevirapine, etravirine and rilpivirine, respectively. The high prevalence of acquired drug resistance in patients followed in two centres of the Liberian capital city, documented after a median of 3 years on a first-line ART regimen, jeopardizes the activity of second-line regimens and highlights the need for virological monitoring in these settings. © The Author 2015.

    Anti-EGFR monoclonal antibodies (anti-EGFR MoAbs) in metastatic colorectal cancer (mCRC) treatment are still not effective in all patients. This study aimed to evaluate the relationship between BRAF V600E mutation and the tumor response of anti-EGFR MoAbs for first-line treatment in mCRC patients. We searched the MEDLINE and EMBASE databases, using the key words that included colorectal cancer, cetuximab, panitumumab, and BRAF mutation and retrieved 445 articles. Among them four were included in the systematic review. Relative risks (RRs) with 95% confidence intervals (CI) for response rate were calculated. BRAF mutation carriers had worse ORR than non-carriers in mCRC patients with KRAS wild-type in first-line treatment whether adding anti-EGFR MoAb to chemotherapy or not (RR = 0.43, [95% CI 0.16-0.75]; RR = 0.38, [95% CI 0.20-0.73]). But in the unselected patients whose KRAS mutation were unknown, BRAF mutation carriers had similar ORR whether adding cetuximab to chemotherapy or not (RR = 0.45, [95% CI 0.18-1.09]; RR = 0.57, [95% CI 0.15-2.23]). In BRAF mutation carriers adding anti-EGFR MoAb to chemotherapy was similar to chemotherapy alone whether in patients with wild-type KRAS or unselected patients (RR = 1.61, [95% CI 0.57-4.47]; RR = 0.71, [95% CI 0.18-2.77]). But in the BRAF mutation non-carriers, adding anti-EGFR MoAb produced a clear benefit in response rate than chemotherapy alone and this advantage was restricted to KRAS wild-type patients (RR = 1.48, [95% CI 1.28-1.71]). BRAF mutation decreases tumor response in first-line treatment whether cetuximab was given or not in patients with KRAS wild-type, and anti-EGFR MoAb produces a clear benefit in response rate in patients with BRAF and KRAS wild-type.

    Although favourable results of pentoxifylline (PTX) used in treatment of severe alcoholic hepatitis patients with a Maddrey discriminant function score ≥ 32 have been previously reported, it is not currently recommended as a first line treatment for alcoholic hepatitis owing to lack of evidence for its efficacy as compared to the standard treatment with corticosteroids. In a very recent issue of World Journal of Gastroenterology, Dr. De BK and colleagues compared for the first time the two treatment modalities head to head in a randomized controlled study, demonstrating the advantage of PTX over corticosteroids in terms of patients' survival and risk-benefit profile. The advantage of PTX over corticosteroids in survival of patients with severe alcoholic hepatitis was found to be related to the prevention of hepatorenal syndrome in their study. This study raises the question of the use of PTX as a standard treatment for severe alcoholic hepatitis. Considering the fact that PTX presented a spectacular efficiency in prevention of hepatorenal syndrome in their study as well as that previous studies have shown that this effect is possibly related to a primary renoprotective action because it is irrelevant of tumor necrosis factor-α synthesis inhibition or improved liver function, we tempted to speculate that PXT might be an effective option for prevention and/or treatment of hepatorenal syndrome complicating other forms of advanced liver disease. This attractive theory remains to be elucidated by pressing future studies in view of the lack of effective treatment modalities for hepatorenal syndrome.

    The humanized monoclonal antibody pertuzumab is the first in a new class of drugs, the human epidermal growth factor receptor (HER) dimerization inhibitors. Given that pertuzumab binds to a different epitope of the HER2 extracellular domain than trastuzumab, combination therapy with pertuzumab plus trastuzumab may result in more comprehensive blockade of HER2 signalling than can be achieved with trastuzumab alone. The efficacy of adding pertuzumab to trastuzumab plus docetaxel for the first-line treatment of HER2-positive metastatic breast cancer was demonstrated in the randomized, double-blind, multinational, phase III CLEOPATRA trial. Both independently assessed progression-free survival (primary endpoint) and investigator-assessed progression-free survival were significantly improved in patients receiving pertuzumab plus trastuzumab and docetaxel compared with those receiving placebo plus trastuzumab and docetaxel. The prespecified interim analysis of survival revealed a strong trend towards a survival benefit associated with pertuzumab, although this was not considered statistically significant. The objective response rate was higher with pertuzumab than with placebo. Intravenous pertuzumab had an acceptable tolerability profile when added to trastuzumab and docetaxel in the CLEOPATRA trial.

    Full Text Available Philip C AmreinHematology-Oncology, Massachusetts General Hospital, Boston, USAAbstract: Dasatinib is a broad spectrum, ATP-competitive, tyrosine kinase inhibitor with low nM activity against Bcr-Abl, Src, and other tyrosine kinases. This activity has allowed dasatinib to emerge as one of the most effective agents in the treatment of chronic myeloid leukemia (CML, and dasatinib has become the third drug over the past 10 years to be FDA approved for first line therapy in this setting. This review consists of papers and reports that recount the recent dramatic progress that has been made in the understanding of CML on a molecular basis leading up to the new targeted therapies, especially the use of dasatinib. As with any drug, treatment with dasatinib has risks and side effects, especially pleural effusions and anti-platelet effects, as outlined in recently published studies. Of interest are the reports of alternative doses and schedules that may be able to circumvent some of these side effects without compromising the effectiveness of this drug. This review outlines the mode of action, pharmacology, effectiveness, and safety of dasatinib in the treatment of CML, and by comparing dasatinib directly with the other tyrosine kinase inhibitors effective in CML, it describes the place in therapy that dasatinib currently holds.Keywords: dasatinib, CML, chronic myeloid leukemia

    OBJECTIVE To investigate the role of maintenance chemotherapy on stage Ⅲ ovarian carcinoma.METHODS A retrospective analysis was conducted of 47 stage Ⅲ ovarian carcinoma patients with clinical complete remission after first-line chemotherapy. Among these patients, 21 cases were treated with maintenance chemotherapy, while the other 26 cases were free of treatment until progression. The 2 groups were compared with respect to progression-free survival (PFS) and overall survival(OS).RESULTS The median PFS and OS were not significantly different between the 2 groups. For those patients, in a subgroup of suboptimal surgery (residual disease >2 cm), the median PFS was 110 weeks and 56 weeks and the median OS was 223 weeks and 157 weeks for the maintenance and non-treated respectively. Both PFS and OS values favoured the maintenance group, P=0.004 and P=0.015 respectively. In a subgroup of optimal surgery (residual disease ≤2 cm), the differences were not significant.CONCLUSION Patients with stage Ⅲ ovarian carcinoma with clinical complete remission may benefit from maintenance chemotherapy, if the residual disease is >2 cm. To those with a residual disease ≤2 cm, the maintenance chemotherapy maybe of no value. So "individualized maintenance chemotherapy" should be conducted in the clinical setting.

    Hypersensitivity reactions are increasingly prevalent, although underrecognized and underreported. Platins induce immunoglobulin E-mediated sensitization; taxenes and some monoclonal antibodies can induce reactions at first exposure. Severe hypersensitivity can preclude first-line therapy. Tryptase level at the time of a reaction is a useful diagnostic tool. Skin testing provides a specific diagnosis. Newer tests are promising diagnostic tools to help identify patients at risk before first exposure. Safe management includes rapid drug desensitization. This review provides information regarding the scope of hypersensitivity and anaphylactic reactions induced by chemotherapy and biological drugs, as well as diagnosis, management, and treatment options.

    Full Text Available Abstract Background DNA repair genes critically regulate the cellular response to chemotherapy and epigenetic regulation of these genes may be influenced by chemotherapy exposure. Restoration of BRCA1 and BRCA2 mediates resistance to platinum chemotherapy in recurrent BRCA1 and BRCA2 mutated hereditary ovarian carcinomas. We evaluated BRCA1, BRCA2, and MLH1 protein expression in 115 sporadic primary ovarian carcinomas, of which 31 had paired recurrent neoplasms collected after chemotherapy. Additionally, we assessed whether promoter methylation of BRCA1, MLH1 or FANCF influenced response to chemotherapy or explained alterations in protein expression after chemotherapy exposure. Results Of 115 primary sporadic ovarian carcinomas, 39 (34% had low BRCA1 protein and 49 (42% had low BRCA2 expression. BRCA1 and BRCA2 protein expression were highly concordant (p Conclusion Low BRCA1 expression in primary sporadic ovarian carcinoma is associated with prolonged survival. Recurrent ovarian carcinomas commonly have increased BRCA1 and/or BRCA2 protein expression post chemotherapy exposure which could mediate resistance to platinum based therapies. However, alterations in expression of these proteins after chemotherapy are not commonly mediated by promoter methylation, and other regulatory mechanisms are likely to contribute to these alterations.

    As it remains uncertain whether patients with advanced gastric cancer who progress after first-line chemotherapy should receive second-line chemotherapy, we attempted to identify the optimal indications for second-line chemotherapy. In this retrospective study, 101 patients were included in univariate and multivariate analyses to identify clinicopathological variables independently associated with longer survival postprogression (SPP), defined as the time from recognition of disease progression on first-line chemotherapy to death from any cause or last follow-up. The median SPP was 340 days. On multivariate analysis, performance status 2 [hazard ratio (HR), 14.234; 95% confidence interval (CI), 2.766-73.258], serum albumin level less than 3.5 g/dl (HR, 2.088; 95% CI, 1.047-4.060) at initiation of second-line chemotherapy, and time to progression less than 170 days on first-line chemotherapy (HR, 2.497; 95% CI, 1.227-5.083) were identified as independent prognostic factors associated with shorter SPP. The median SPP was 496, 375, and 232 days in patients with 0, 1, and 2 of these 3 negative prognostic factors, respectively (P=0.0002). The present study suggests that second-line chemotherapy would not be beneficial in patients with two or more of the following three negative prognostic factors: performance status 2, serum albumin less than 3.5 g/dl at initiation of second-line chemotherapy and time to progression less than 170 days on first-line chemotherapy.

    The advent of endoscopic sphenopalatine artery ligation (ESPAL) for the control of posterior epistaxis provides an effective, low-morbidity treatment option. In the current practice algorithm, ESPAL is pursued after failure of posterior packing. Given the morbidity and limited effectiveness of posterior packing, we sought to determine the cost-effectiveness of first-line ESPAL compared to the current practice model. A standard decision analysis model was constructed comparing first-line ESPAL and current practice algorithms. A literature search was performed to determine event probabilities and published Medicare data largely provided cost parameters. The primary outcomes were cost of treatment and resolution of epistaxis. One-way sensitivity analysis was performed for key parameters. Costs for the first-line ESPAL arm and the current practice arm were $6450 and $8246, respectively. One-way sensitivity analyses were performed for key variables including duration of packing. The baseline difference of $1796 in favor of the first-line ESPAL arm was increased to $6263 when the duration of nasal packing was increased from 3 to 5 days. Current practice was favored (cost savings of $437 per patient) if posterior packing duration was decreased from 3 to 2 days. This study demonstrates that ESPAL is cost-saving as first-line therapy for posterior epistaxis. Given the improved effectiveness and patient comfort of ESPAL compared to posterior packing, ESPAL should be offered as an initial treatment option for medically stable patients with posterior epistaxis. © 2013 ARS-AAOA, LLC.

    The aim of this study was to evaluate the efficacy and safety of intravenous valproate (i.v. VPA) as first-line treatment of status epilepticus (SE) and seizure clusters in selected patient populations. We enrolled 23 patients (11 females and 12 males; mean age: 61 years) with SE who received i.v. VPA as first-line therapy (25 mg/kg in 100 mL saline infused over 15 min). ECG tracing was monitored before, during, and after infusion. Liver function and serum ammonia tests were conducted after 24 and 72 h of treatment. We evaluate the response of SE to i.v. therapy and short-term outcome. In 15 out of 23 patients (65%), i.v. VPA was effective. In our population, we retrospectively identified three different subgroups: patients with cardiorespiratory comorbidities discouraging the use of traditional SE first-line drugs, patients with specific epileptic subsyndromes (such as idiopathic generalized epilepsy), and patients affected by psycho-organic syndromes. No significant adverse effects were detected. Our study shows the clinical relevance of i.v. VPA as first-line therapy of SE in patients with medical conditions contraindicating the use of traditional first-line antiepileptic drugs for SE, and in those presenting with specific forms of SE.

    Although switching of antiretroviral therapy (ART) is a valid approach for addressing treatment failure in patients with human immunodeficiency virus (HIV), ART changes among those who are well maintained on their current regimens may lead to the development of new side effects or resistance. To examine the effect of first-line regimen switching on subsequent health care utilization and cost among stable HIV patients. This was a retrospective claims data study of adult patients with HIV who initiated ART between 2007 and 2013 and had been treated with their initial regimens for at least 6 continuous months. Those with evidence of pregnancy or HIV-2 were excluded. Patients who underwent an ART change were assigned to a switcher cohort; a nonswitcher cohort was then generated by matching up to 20 nonswitchers for each switcher, with replacement. The index date was the date of the first ART change for switchers and was the claim date closest to the corresponding switcher's switch date for nonswitchers. Patient characteristics at baseline and post-index annualized health care utilization and costs were analyzed descriptively and with multivariable models. Analyses were performed in the full population and among patients designated as virologically stable (had undetectable viral ribonucleic acid [RNA] for 90 days pre-index) and virologically and clinically stable (had undetectable viral RNA and no apparent clinical reason for switching ART). The study population consisted of 6,983 individuals, which included 927 switchers (168 virologically stable; 55 virologically+clinically stable), who were matched with replacement with 18,511 nonswitcher comparators. The switcher cohort was 88.8% male (mean age 43.8 years). Mean preindex and follow-up treatment durations for switchers and nonswitchers were 1.8 years and 1.5 years, respectively; demographic characteristics, pre-index treatment duration, and follow-up duration were similar between cohorts.

    Our objective was to estimate the cost effectiveness of ofatumumab plus chlorambucil (OChl) versus chlorambucil in patients with chronic lymphocytic leukaemia for whom fludarabine-based therapies are considered inappropriate from the perspective of the publicly funded healthcare system in Canada. A semi-Markov model (3-month cycle length) used survival curves to govern progression-free survival (PFS) and overall survival (OS). Efficacy and safety data and health-state utility values were estimated from the COMPLEMENT-1 trial. Post-progression treatment patterns were based on clinical guidelines, Canadian treatment practices and published literature. Total and incremental expected lifetime costs (in Canadian dollars [$Can], year 2013 values), life-years and quality-adjusted life-years (QALYs) were computed. Uncertainty was assessed via deterministic and probabilistic sensitivity analyses. The discounted lifetime health and economic outcomes estimated by the model showed that, compared with chlorambucil, first-line treatment with OChl led to an increase in QALYs (0.41) and total costs ($Can27,866) and to an incremental cost-effectiveness ratio (ICER) of $Can68,647 per QALY gained. In deterministic sensitivity analyses, the ICER was most sensitive to the modelling time horizon and to the extrapolation of OS treatment effects beyond the trial duration. In probabilistic sensitivity analysis, the probability of cost effectiveness at a willingness-to-pay threshold of $Can100,000 per QALY gained was 59 %. Base-case results indicated that improved overall response and PFS for OChl compared with chlorambucil translated to improved quality-adjusted life expectancy. Sensitivity analysis suggested that OChl is likely to be cost effective subject to uncertainty associated with the presence of any long-term OS benefit and the model time horizon.

  7. Melanocytes and melanin represent a first line of innate immunity against Candida albicans.

    Melanocytes are dendritic cells located in the skin and mucosae that synthesize melanin. Some infections induce hypo- or hyperpigmentation, which is associated with the activation of Toll-like receptors (TLRs), especially TLR4. Candida albicans is an opportunist pathogen that can switch between blastoconidia and hyphae forms; the latter is associated with invasion. Our objectives in this study were to ascertain whether C. albicans induces pigmentation in melanocytes and whether this process is dependent on TLR activation, as well as relating this with the antifungal activity of melanin as a first line of innate immunity against fungal infections. Normal human melanocytes were stimulated with C. albicans supernatants or with crude extracts of the blastoconidia or hyphae forms, and pigmentation and TLR2/TLR4 expression were measured. Expression of the melanosomal antigens Melan-A and gp100 was examined for any correlation with increased melanin levels or antifungal activity in melanocyte lysates. Melanosomal antigens were induced earlier than cell pigmentation, and hyphae induced stronger melanization than blastoconidia. Notably, when melanocytes were stimulated with crude extracts of C. albicans, the cell surface expression of TLR2/TLR4 began at 48 h post-stimulation and peaked at 72 h. At this time, blastoconidia induced both TLR2 and TLR4 expression, whereas hyphae only induced TLR4 expression. Taken together, these results suggest that melanocytes play a key role in innate immune responses against C. albicans infections by recognizing pathogenic forms of C. albicans via TLR4, resulting in increased melanin content and inhibition of infection.

    Vascular endothelial growth factor receptor inhibitors, mammalian target of rapamycin inhibitors, and tyrosine kinase inhibitors are approved for metastatic renal cell cancer. Proteinuria can occur, but there is limited data regarding the incidence, monitoring, and management in metastatic renal cell cancer patients. Our primary objective was to describe the incidence and severity of proteinuria in metastatic renal cell cancer patients treated in the first-line setting with pazopanib, bevacizumab, or everolimus. We conducted a retrospective review of patients with metastatic renal cell cancer enrolled from January 2011-April 2013 in a phase II trial. Baseline and toxicity data were extracted from the electronic medical record. Descriptive statistics were used. In all, 129 patients were eligible for analysis. The overall incidence of proteinuria was 81%, with most events being Grade 1 or 2. The incidence of proteinuria was 80% (n = 35) for pazopanib, 64% (n = 25) for bevacizumab, and 96% (n = 44) for everolimus. At peak proteinuria, 80% (n = 28), 64% (n = 16), and 80% (n = 35) of patients on pazopanib, bevacizumab, and everolimus, respectively, were managed with continued monitoring at the same dose. The overall incidence of Grades 3 and 4 events was 24% (n = 6) and found in the bevacizumab group. A high incidence of proteinuria with minor severity within each class was demonstrated. It may be reasonable to continue therapy at the same dose for Grade 1 or 2 proteinuria. Treatment modification or discontinuation of therapy may be warranted with Grade 3 or 4 proteinuria. © The Author(s) 2014.

    Non-adherence to disease-modifying therapies (DMTs) in multiple sclerosis may be associated with reduced efficacy. We assessed compliance, the reasons for non-compliance, treatment satisfaction, and quality of life (QoL) of patients treated with first-line therapies. A cross-sectional, multicenter study was conducted that included relapsing multiple sclerosis patients. Compliance in the past month was assessed using Morisky-Green test. Seasonal compliance and reasons for non-compliance were assessed by an ad-hoc questionnaire. Treatment satisfaction and QoL were evaluated by means of TSQM and PRIMUS questionnaires. A total of 220 patients were evaluated (91% relapsing-remitting); the mean age was 39.1 years, 70% were female, and the average time under treatment was 5.4 years. Subcutaneous interferon (IFN) β-1b was used in 23% of the patients, intramuscular IFN β-1a in 21%, subcutaneous IFN β-1a in 37%, and with glatiramer acetate in 19%. The overall compliance was 75%, with no significant differences related to the therapy, and 81% did not report any seasonal variation. Compliant patients had significantly lower disability scores and time of diagnosis, and greater satisfaction with treatment and its effectiveness. Discomfort and flu-like symptoms were the most frequent reasons for non-compliance. The satisfaction and QoL were associated with less disability and number of therapeutic switches. The rate of compliance, satisfaction and QoL in multiple sclerosis patients under DMTs is high, especially for those newly diagnosed, less disabled, and with fewer therapeutic switches. Discomfort and flu-like symptoms associated with injected therapies significantly affect adherence. Copyright © 2013 Sociedad Española de Neurología. Published by Elsevier España, S.L.U.

    The combination of docetaxel and cisplatin is an effective first-line regimen in patients with advanced non-small cell lung cancer. However, the recommended three-weekly schedule is associated with frequent neutropenia and infections. Because of the toxicity of cisplatin, patients may need to be hospitalized to ensure adequate hydration. The aim of this study was to assess the efficacy and tolerability of a weekly schedule of docetaxel and cisplatin. Patients with inoperable stage International Union Against Cancer IIIB (malignant effusion) or IV non-small cell lung cancer received docetaxel (35 mg/m(2), 30 minutes infusion) and cisplatin (25 mg/m(2), 30 minutes infusion) on days 1, 8, and 15, every 4 weeks for 4 to 6 cycles. Ondansetron (8 mg) and dexamethasone (8 mg) were given intravenously before chemotherapy. The patients received oral dexamethasone 2 x 4 mg daily from the day before until the day after chemotherapy. NK1-antagonists were given at the investigator's discretion. The majority of patients was treated in outpatient departments. Safety was assessed using CTCAE v3.0. The primary end point was response rate (RECIST). Forty-four patients were included. Twelve of 44 patients achieved an objective response (11 partial, 1 complete, intent-to-treat response rate 27%). Median time to progression was 4.4 months (95% confidence interval: 4.0-4.7) and median survival 9.6 months (95% confidence interval: 2.9-16.2). Patients received a median of three full cycles. Four patients (9%) required dose reductions. No cases of febrile neutropenia or grade 2 to 4 thrombocytopenia were observed. One patient (2%) experienced grade 3/4 nausea and vomiting. Weekly docetaxel-cisplatin demonstrated comparable efficacy with three-weekly schedules. Although the frequencies of neutropenia and febrile neutropenia were low, non-neutropenic infections remained a problem. Because of relatively short hydration, the schedule can be safely administered in an outpatient setting.

    Optimal chemotherapy regimen for peripheral T-cell lymphomas (PTCL) has not been fully defined. This study aimed to evaluate the optimal chemotherapy regimen in the first-line treatment for PTCL patients. Between 2003 and 2014, 93 consecutive patients with PTCL were enrolled in this study. Of 93 patients, 42 patients received CHOPE, 40 patients with CHOP, and 11 patients with GDP regimen. Response could be evaluated in 88 of 93 patients at the end of primary treatment. The CR rate for patients received CHOP (n = 38), CHOPE (n = 39), and GDP (n = 11) were 28.9, 51.3, and 45.5%, respectively, (P = 0.132) with an ORR of 65.8, 76.9, and 90.9%, respectively, (P = 0.210). The median follow-up time was 17.1 (1.4-108.3) months. Median progression-free survival (PFS) in CHOP (n = 40), CHOPE (n = 42), and GDP (n = 11) groups were 6.0, 15.3, and 9.7 months (P = 0.094) with 1-year PFS of 35.0, 54.8, and 45.5%, respectively, (P = 0.078). One-year OS for patients received CHOP (n = 40), CHOPE (n = 42), and GDP (n = 11) were 65.0, 83.3, and 100%, respectively, (P = 0.013) (CHOP vs CHOPE, P = 0.030; CHOP vs GDP, P = 0.024; CHOPE vs GDP, P = 0.174). CHOPE has a trend to improve CR rate, 1-year PFS and OS compared with CHOP alone. GDP shows promising efficacy which worth further exploration in large cohort studies. Clinical experience presented in this study may serve as reference for future large cohort studies.

    Maintenance therapy (MT) with pemetrexed has been shown to improve overall and progression-free survival of patients with non-squamous non-small cell lung cancer (NSCLC), without impairing patients' health-related quality of life (HRQOL) substantially. Comprehensive data on HRQOL under real-life conditions are necessary to enable informed decision-making. This study aims to (1) assess HRQOL during first-line chemotherapy and subsequent MT and (2) record patients' and physicians' reasons leading to clinical decisions on MT. Patients treated for NSCLC at three Austrian medical centres were included. HRQOL was assessed at every chemotherapy cycle using the EORTC QLQ-C30/+LC13 questionnaire. Semi-structured interviews were conducted before MT initiation and at the time of discontinuation to evaluate patients' and physicians' reasons for treatment decisions. Longitudinal QOL analysis was based on linear mixed models. Sixty-one (73%) out of 84 patients were considered for MT. Thirty-six patients (43%) received MT and 29 (35%) discontinued therapy. Decisions on MT initiation (in 20 cases by the physician vs 4 by the patient) and discontinuation (19 vs 10) were mainly voiced by the physician. Treatment toxicity of first-line chemotherapy was the main reason for rejection of MT in patients with stable disease and was more often indicated by patients than clinicians. HRQOL data were collected from 83 patients at 422 assessment time points and indicated significantly lower symptom severity during MT compared with first-line therapy for nausea and vomiting (p = 0.006), sleep disturbances (p loss (p = 0.043), constipation (p = 0.017) and chest pain (p = 0.022), and a deterioration in emotional functioning (p = 0.023) and cognitive functioning (p = 0.044) during MT. Our results indicate that HRQOL and symptom burden improve between first-line treatment to MT in some respects, although some late toxicity persists. Discrepancies between patients' and physicians

    The objective of this study was to determine the outcome of using ultrasound-guided local methotrexate injection as the first-line treatment of cesarean scar pregnancy (CSP). A literature review was performed on all eligible reports using this modality as the first-line treatment of CSP. Relevant publications were obtained from the PubMed electronic database from inception to December 2014. Ninety-six cases from 95 women reported in 17 articles were reviewed. The success rate was 73.9% after a single local methotrexate injection. An accumulated success rate of 88.5% could be achieved after additional local or intramuscular methotrexate administration. Eleven cases (11.5%) failed methotrexate treatment and required surgical interventions. Except for women with serum human chorionic gonadotropin levels higher than 100 000 IU/L, ultrasound-guided local methotrexate injection could be considered as a first-line treatment modality for CSP.

    Based on demonstrated favourable risk-benefit profiles, taxanes remain a key component in the first-line standard of care for advanced non-small-cell lung cancer (nsclc) and nsclc subtypes. In 2012, a novel taxane, nab-paclitaxel (Abraxane: Celgene Corporation, Summit, NJ, U.S.A.), was approved, in combination with carboplatin, for the first-line treatment of locally advanced or meta-static nsclc. The approval was granted because of demonstrated improved antitumour activity and tolerability compared with solvent-based paclitaxel-carboplatin in a phase iii trial. This review focuses on the evolution of first-line taxane therapy for advanced nsclc and the new options and advances in taxane therapy that might address unmet needs in advanced nsclc.

    Service is a special product. It is intangible and unstored, so service er-rors are not avoided. Once service errors appear, the first line staffs who keep di-rect touch with customers wil play an important role in service recovery. The staffs' negative emotions during the recovery service should be recovered by internal ser-vice recovery. In this paper, critical incident technique is applied to analyse the re-covery strategies expected by the first line staff and the internal service recovery strategies such as inspiring, authorization, training and psychology service are put forward. the strategy most expected by the staff is reward.

    The fluoroquinolone moxifloxacin has potent activity against Mycobacterium tuberculosis and has been recommended by the guidelines for the treatment of pulmonary tuberculosis (TB). Monotherapy is not recommended by the guidelines and only a few studies have evaluated the efficacy and safety of moxifloxacin plus standard first-line therapy in treating TB. The purpose of this meta-analysis was to further investigate the efficacy and safety of moxifloxacin plus standard therapy compared with standard therapy alone in treating patients with pulmonary TB. Medline, Cochrane, EMBASE and Google Scholar (until February 12, 2015) were searched for studies that evaluated the clinical efficacy and tolerability of moxifloxacin in the treatment of pulmonary TB. Rate of culture conversion and serious adverse events (SAEs) were assessed. Risk of bias and sensitivity analysis, using the leave-one-out approach, was used to assess the robustness of the findings. Six studies were included in the meta-analysis which covered 2056 patients with pulmonary TB. For all included studies, the drug regimens at least contained rifampicin and pyrazinamide and the length of treatment was at least eight weeks. The odds ratio (OR) for the negative culture rate for moxifloxacin plus first-line medications compared first-line medications alone (the control group) was 1.60 with 95% CI in 0.93-2.74 (P = 0.089), indicating the moxifloxacin plus first-line medications had no significantly greater rate of culture conversion compared with first-line medication alone. The odds ratio of SAEs for moxifloxacin plus first-line medications compared with first-line medications alone found no difference in rate of SAEs between treatment groups (OR = 0.94, P = 0.862). In conclusion, our meta-analysis suggests that there was a trend for the addition of moxifloxacin to standard first-line therapy for non-drug resistant TB resulted to increase the rate of culture conversion but this effect requires confirmation

    Abstract Background: Simultaneous multiple myeloma (MM) and pulmonary adenocarcinoma is a rare occurrence, and thus, treatment is a challenge. This study reports on 1 such case of MM with concurrent lung cancer, where an accurate diagnosis was made and the patient underwent treatment for both cancers. Case summary: A 68-year-old man presented with 2 months of progressive lower back pain. Visualization with magnetic resonance imaging (MRI) revealed multiple collapsed vertebrae from T12 to S3, as well as an altered signal intensity at the T3 vertebra. The patient was diagnosed with MM upon examination. A chest computed tomography (CT) scan revealed a round mass in the left lower lobe of the lungs, and a CT-guided needle biopsy uncovered a moderately differentiated adenocarcinoma. There were no additional notable findings in the left lung using positron emission tomography computed tomography (PET-CT). Therefore, a diagnosis of MM with pulmonary adenocarcinoma was made. Surgery was performed to excise the lung cancer. Bortezomib was used as first-line induction therapy against both tumors and lenalidomide was used for maintenance. The patient went into complete remission. Using this combined chemotherapy, the patient has survived for over 3 years since a diagnosis was made despite relapsing twice after the first year. Conclusion: This report clearly delineates the diagnosis and treatment of a rare case of synchronous MM and pulmonary adenocarcinoma, as well as depicts a potentially positive outcome for the patient. It also overviews some diagnostic and therapeutic implications for clinicians. PMID:28072730

    Full Text Available Abstract Background Ugandan national guidelines recommend initiation of combination antiretroviral therapy (cART at CD4+ T cell (CD4 count below 350 cell/μl, but the implementation of this is limited due to availability of medication. However, cART initiation at higher CD4 count increases survival, albeit at higher lifetime treatment cost. This analysis evaluates the cost-effectiveness of initiating cART at a CD4 count between 250–350 cell/μl (early versus Methods Life expectancy of cART-treated patients, conditional on baseline CD4 count, was modeled based on published literature. First-line cART costs $192 annually, with an additional $113 for patient monitoring. Delaying initiation of cART until the CD4 count falls below 250 cells/μl would incur the cost of the bi-annual CD4 count tests and routine maintenance care at $85 annually. We compared lifetime treatment costs and disability adjusted life-expectancy between early vs. delayed cART for ten baseline CD4 count ranges from 250-350 cell/μl. All costs and benefits were discounted at 3% annually. Results Treatment delay varied from 6–18 months. Early cART initiation increased life expectancy from 1.5-3.5 years and averted 1.33–3.10 disability adjusted life years (DALY’s per patient. Lifetime treatment costs were $4,300–$5,248 for early initiation and $3,940–$4,435 for delayed initiation. The cost/DALY averted of the early versus delayed start ranged from $260–$270. Conclusions In HIV-positive patients presenting with CD4 count between 250-350 cells/μl, immediate initiation of cART is a highly cost-effective strategy using the recommended one-time per capita GDP threshold of $490 reported for Uganda. This would constitute an efficient use of scarce health care funds.

    Little is known about survival outcomes of HIV patients on first-line antiretroviral therapy (ART) on a large-scale in India, or facility level factors that influence patient survival to guide further improvements in the ART program in India. We examined factors at the facility level in addition to patient factors that influence survival of adult HIV patients on ART in the publicly-funded ART program in a high- and a low-HIV prevalence state. Retrospective chart review in public sector ART facilities in the combined states of Andhra Pradesh and Telangana (APT) before these were split in 2014 and in Rajasthan (RAJ), the high- and a low-HIV prevalence states, respectively. Records of adults initiating ART between 2007-12 and 2008-13 in APT and RAJ, respectively, were reviewed and facility-level information collected at all ART centres and a sample of link ART centres. Survival probability was estimated using Kaplan-Meier method, and determinants of mortality explored with facility and patient-level factors using Cox proportional hazard model. Based on data from 6581 patients, the survival probability of ART at 60 months was 76.3 % (95 % CI 73.0-79.2) in APT and 78.3 % (74.4-81.7) in RAJ. The facilities with cumulative ART patient load above the state average had lower mortality in APT (Hazard ratio [HR] 0.74, 0.57-0.95) but higher in RAJ (HR 1.37, 1.01-1.87). Facilities with higher proportion of lost to follow-up patients in APT had higher mortality (HR 1.47, 1.06-2.05), as did those with higher ART to pre-ART patient ratio in RAJ (HR 1.62, 1.14-2.29). In both states, there was higher hazard for mortality in patients with CD4 count 100 cells/mm(3) or less at ART initiation, males, and in patients with TB co-infection. These data from the majority of facilities in a high- and a low-HIV burden state of India over 5 years reveal reasonable and similar survival outcomes in the two states. The facilities with higher ART load in the longer established ART program in

    Very few reliable clinical data about the use of radioimmunotherapy in aggressive B-cell lymphoma exist. Patients with aggressive B-cell lymphoma registered in the international RIT-Network were analysed with regard to prior treatment, response and side effects. The RIT-Network is a web-based registry that collects observational data from radioimmunotherapy-treated patients with malignant lymphoma across 13 countries. This analysis included 215 with aggressive B-cell lymphoma out of 232 patients registered in the RIT-Network. Histological subtypes were as follows: 190 diffuse large B-cell, 15 primary mediastinal, 9 anaplastic large cell, and 1 intravascular lymphoma. The median age of the patients was 62 years (range 17 - 88), with 27 % above the age of 70 years. Radioimmunotherapy was mainly used as consolidation after first-line or second-line chemotherapy (56.1 %), as part of third-line to eighth-line therapy for relapse (16.4 %), and in refractory disease (12.2 %). Grade IV neutropenia and thrombopenia and grade III anaemia were observed. The median time to recovery of blood count was 81 days (range 0 - 600 days). The overall response rate was 63.3 %. The complete response rate was 76.4 % in patients treated as part of first-line therapy, and 44.3 % in patients with relapse. Mean overall survival in first-line therapy patients was 32.7 months and 14.0 months in patients with relapse or refractory disease, respectively. Most patients with aggressive B-cell lymphoma in the RIT-Network received radioimmunotherapy as consolidation after first-line therapy with excellent complete remission and overall survival rates compared to published data. In relapsed aggressive B-cell lymphoma, radioimmunotherapy is a safe and feasible treatment leading to satisfactory response rates with acceptable toxicity. (orig.)

    The tyrosine kinase inhibitor (TKI) imatinib has become an integral part of front-line therapy for Philadelphia chromosome-positive acute lymphoblastic leukaemia, with remission rates exceeding 90% irrespective of whether imatinib is given alone or combined with chemotherapy. Treatment outcome with imatinib-based regimens has improved compared with historic controls, but most patients who do not undergo allogeneic stem cell transplantation (SCT) eventually relapse. Second-generation TKI, e.g. dasatinib and nilotinib, show activity against most of the bcr-abl tyrosine kinase domain mutations involved in acquired imatinib resistance, but clinical benefit is generally short lived. Accordingly, SCT in first complete response is considered to be the best curative option. Strategies to improve outcome in patients ineligible for transplantation as well as after SCT include front-line treatment with more effective TKI to increase molecular response rates. Following SCT, the pre-emptive use of imatinib appears to reduce the relapse rate. Novel immunotherapeutic interventions and combinations of TKI are also being explored.

    In 2001, caspofungin received market authorisation by the FDA and EMA and is globally licensed for several indications, including candidiasis, empirical antifungal therapy in patients with neutropenic fever of unknown origin and treatment of invasive aspergillosis in patients refractory to or intolerant of amphotericin B, lipid formulations of amphotericin B or itraconazole. Despite the lack of phase III data in first-line treatment of invasive aspergillosis, increasing evidence supports the use of first-line therapy. Here, we analyse the evidence of therapeutic activity, represented by favourable response rates, of caspofungin for invasive aspergillosis. A systematic literature search was conducted to identify international presentations and papers reporting monotherapy with caspofungin. Efficacy data are summarised separately for first-line and salvage therapy. Thirty-one papers and published abstracts reported caspofungin therapy for aspergillosis. Fifteen full papers and two abstracts fulfilled the criteria of reporting significant outcome data for caspofungin monotherapy for invasive aspergillosis. Consistent with other analyses and the known safety profile, few adverse events and associated terminations of caspofungin medication have been reported. Although a randomised, comparative, prospective study using caspofungin in this indication is still lacking, growing evidence supports the efficacy of this echinocandin not only for salvage but also for first-line therapy.

Molecular forms of Sb (V complexes are commercialized as sodium stibogluconate (Pentostam® and meglumine antimoniate (MA (Glucantime®. Ever-increasing drug resistance in the parasites limits the use of antimonials, due to the low drug concentrations being administered against high parasitic counts. Sb5+ toxicity provokes severe side effects during treatment. To enhance therapeutic potency and to increase Sb (V concentration within the target cells, we decided to try a new active substance form, a hydrosol of Sb2O5⋅nH2O nanoparticles (NPs, instead of molecular drugs. Methodology/principal findings: Sb2O5⋅nH2O NPs were synthesized by controlled SbCl5 hydrolysis in a great excess of water. Sb2O5⋅nH2O phase formation was confirmed by X-ray diffraction. The surface of Sb (V NPs was treated with ligands with a high affinity for target cell membrane receptors. The mean particle size determined by dynamic light scattering and transmission electron microscopy was ~35–45 nm. In vitro tests demonstrated a 2.5–3 times higher antiparasitic activity of Sb (V nanohybrid hydrosols

    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.

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

    Full Text Available Jeffrey Bryan, Gautam BorthakurDepartment of Leukemia, The University of Texas MD Anderson Cancer Center, Houston, TX, USAAbstract: Chronic lymphocytic leukemia (CLL is a biologically heterogeneous illness that primarily afflicts the elderly. For many decades, the initial therapy for most patients requiring treatment was limited to single-agent alkylator therapy. Within the last two decades, we have seen remarkable progress in understanding the biology of CLL and the development of more effective treatment strategies that have employed monoclonal antibodies, such as rituximab (anti-CD20. Furthermore, recognition of the synergy between fludarabine, cyclophosphamide, and rituximab (FCR prompted investigators to explore the clinical activity of FCR in Phase II and III trials in patients with relapsed/refractory or previously untreated CLL. On the basis of these findings, the US Food and Drug Administration (FDA recently approved rituximab in combination with fludarabine and cyclophosphamide for the treatment of patients with relapsed/refractory or previously untreated CD20-postive CLL. Recent data from a randomized Phase III trial has confirmed improved overall survival with FCR in patients with previously untreated CLL. However, FCR is not for everyone. More tolerable regimens using rituximab for the elderly and less fit patients are being pursued in clinical trials. Recent Phase II trials have explored potentially less myelosuppressive approaches by using lower doses of fludarabine and cyclophosphamide, replacing fludarabine with pentostatin, and combining rituximab with chlorambucil. Furthermore new biomarkers predictive of early disease progression have prompted investigators to explore the benefits of early treatment with rituximab combined with other agents. In addition to the proven utility of rituximab as a frontline agent for CLL, rituximab has a favorable toxicity profile both as a single agent and in combination with chemotherapy. The

    Full Text Available Abstract Background Integument-related toxicities are common during epidermal growth factor receptor (EGFR-targeted therapy. Panitumumab is a fully human monoclonal antibody targeting the EGFR that significantly improves progression-free survival when added to chemotherapy in patients with metastatic colorectal cancer who have wild-type (WT KRAS tumours. Primary efficacy and tolerability results from a phase II single-arm study of first-line panitumumab plus FOLFIRI in patients with metastatic colorectal cancer have been reported. Here we report additional descriptive tolerability and quality of life data from this trial. Methods Integument-related toxicities and quality of life were analysed; toxicities were graded using modified National Cancer Institute Common Toxicity Criteria. Kaplan-Meier estimates of time to and duration of first integument-related toxicity were prepared. Quality of life was measured using EuroQoL EQ-5D and EORTC QLQ-C30. Best overall response was analysed by skin toxicity grade and baseline quality of life. Change in quality of life was analysed by skin toxicity severity. Results 154 patients were enrolled (WT KRAS n = 86; mutant KRAS n = 59; most (98% experienced integument-related toxicities (most commonly rash [42%], dry skin [40%] and acne [36%]. Median time to first integument-related toxicity was 8 days; median duration was 334 days. Overall, proportionally more patients with grade 2+ skin toxicity responded (56% compared with those with grade 0/1 (29%. Mean overall EQ-5D health state index scores (0.81 vs. 0.78, health rating scores (72.5 vs. 71.0 and QLQ-C30 global health status scores (65.8 vs. 66.7 were comparable at baseline vs. safety follow-up (8 weeks after completion, respectively and appeared unaffected by skin toxicity severity. Conclusions First-line panitumumab plus FOLFIRI has acceptable tolerability and appears to have little impact on quality of life, despite the high incidence of integument

    Background Three randomised trials have demonstrated that combining bevacizumab with first-line chemotherapy significantly improves progression-free survival versus chemotherapy alone in HER2-negative locally recurrent/metastatic breast cancer (LR/mBC).However,data from Chinese populations are limited and possible differences between ethnic and geographic populations are unknown.This study was conducted to determine whether there are differences in safety and efficacy in patients with HER2-negative LR/mRC between Chinese and Western populations after they receive first-line bevacizumab combined with taxane-based therapy.Methods In the single-arm,open-label,Avastin Therapy for Advanced Breast Cancer (ATHENA) study (NCT00448591),patients with H ER2-negative LR/mBC received first-line bevacizumab (investigator's choice of 10 mg/kg every 2 weeks or 15 mg/kg every 3 weeks) combined with taxane-based therapy.The primary endpoint was safety profile and the secondary is time to progression (TTP).A subpopulation analysis was conducted to assess safety and efficacy in Chinese patients.Results Of 2264 patients treated in ATHENA,202 were enrolled in China.Bevacizumab was combined with docetaxel in 90% of Chinese patients and paclitaxel in 10%.The most common grade 3/4 adverse events were diarrhoea (in 5.0% of patients) and hypertension (in 2.5% of patients).Grade 3/4 proteinuria occurred in 0.5%.After median follow-up of 17.6 months and events in 56% of patients,median TTP was 9.0 months (95%C/,8.4-11.1).Overall survival data were immature.Conclusions We found no evidence of increased bevacizumab-related toxicity or reduced efficacy in Chinese LR/mBC patients receiving first-line bevacizumab-taxane therapy compared with predominantly Western populations.The safety profile was generally similar to previously reported LR/mBC trials.Subtle differences may be attributable to different lifestyle and cardiovascular risk factors in Chinese patients compared with the

    Non-bismuth quadruple sequential therapy (SEQ) comprising a first induction phase with a dual regimen of amoxicillin and a proton pump inhibitor (PPI) for five days followed by a triple regimen phase with a PPI, clarithromycin and metronidazole for another five days, has been suggested as a new first-line treatment option to replace the standard triple therapy (STT) comprising a proton pump inhibitor (PPI), clarithromycin and amoxicillin, in which eradication proportions have declined to disappointing levels. To conduct a meta-analysis of randomised controlled trials (RCTs) comparing the efficacy of a SEQ regimen with STT for the eradication of H. pylori infection, and to compare the incidence of adverse effects associated with both STT and SEQ H. pylori eradication therapies. We conducted bibliographical searches in electronic databases, and handsearched abstracts from Congresses up to April 2015. We sought randomised controlled trials (RCTs) comparing 10-day SEQ and STT (of at least seven days) for the eradication of H. pylori. Participants were adults and children diagnosed as positive for H. pylori infection and naïve to H. pylori treatment. We used a pre-piloted, tabular summary to collect demographic and medical information of included study participants as well as therapeutic data and information related to the diagnosis and confirmatory tests.We evaluated the difference in intention-to-treat eradication between SEQ and STT regimens across studies, and assessed sources of the heterogeneity of this risk difference (RD) using subgroup analyses.We evaluated the quality of the evidence following Cochrane standards, and summarised it using GRADE methodology. We included 44 RCTs with a total of 12,284 participants (6042 in SEQ and 6242 in STT). The overall analysis showed that SEQ was significantly more effective than STT (82% vs 75% in the intention-to-treat analysis; RD 0.09, 95% confidence interval (CI) 0.06 to 0.11; P STT were greater in Europe (RD 0.16, 95

    2012-09-01

    Full Text Available Aspergillosis remains to be a life-threatening complication in immunocompromised patients. However, Aspergillus infection can be observed in non-immunocompromised individuals in rare cases. We report a case of liver aspergilloma in a chronic aplastic anemia patient under relatively intact immune status. Therapeutic strategy for this rare condition was extensively discussed and caspofungin acetate single agent first-line therapy was applied after careful consideration. Encouraging clinical and radiologic improvements were achieved in response to the antifungal salvage. Our long-term follow-up study also revealed a favorable prognosis. Based on this experience, we suggest caspofungin acetate as first-line therapy for treatment plans of liver aspergilloma.

    To investigate the different outcomes in patients with metastatic renal cell carcinoma (mRCC) who receive a reduced first-line dose of sunitinib or pazopanib compared to those who continue at the standard dose. All the patients treated in 11 oncological centers in Italy for mRCC who started first-line treatment with sunitinib or pazopanib at the standard dose. Descriptive statistical tests were used to highlight differences among groups. Survival was estimated by the Kaplan-Meier method and compared across the groups using log-rank tests, the Cox proportional hazards model adjusted for statistically significant variables was also done. A total of 591 patients were included in the study. Of these, 45.7% received a reduced dose of sunitinib or pazopanib after a median treatment time of 3.6 months at the standard dose. The median overall survival in the patients who continued to receive the standard dose was 24.0 months compared to 49.4 months for those who received a reduced dose (hazard ratio = 1.80; 95% CI: 1.42-2.29; P<0.001). Only 45% of the patients received second-line therapy: 42.5% had an mTOR and 54.1% a tyrosine kinase inhibitor. Second-line overall survival was 19.8 and 11.8 months, respectively, in the patients who received, or did not, a reduced dose during first-line therapy (P = 0.007). Toxicity-related dose reduction is a common event in mRCC patients who have started first-line therapy with either sunitinib or pazopanib. This is positively related to the outcomes of both first- and second-line therapy. Copyright © 2017 Elsevier Inc. All rights reserved.

    Chemotherapy stands today for cancer. In 1909, Paul Ehrlich (1854-1915) advocates the use of arsphenamine by infusion. So, he is considered as the father of chemotherapy. In fact, the first to have thought through chemotherapy was Sir Christopher Wren (1632-1723). In 1676, ideas and experiments on animals had sufficiently progressed to allow Michel Ettmuller (1644-1683) to publish the first edition of his book and several others were printed until 1753. In this book, he describes the first intravenous treatment, it sets the first indications, dosages and different products which can be used. However this method has been forgotten until the late 19th century.

    Full Text Available Previous studies in small-cell lung cancer (SCLC patients have mainly focused on exploring neurocognitive deficits associated with prophylactic cranial irradiation (PCI. Little is known about functional brain alterations that might occur due to chemotherapy treatment in this population before PCI is administered. For this reason, we used resting-state functional Magnetic Resonance Imaging (fMRI to examine potential functional connectivity disruptions in brain networks, including the Default Mode Network (DMN, the Sensorimotor Network, and the Task-Positive Network (TPN. Nineteen SCLC patients after platinum-based chemotherapy treatment and thirteen controls were recruited in the current study. ROI-to-ROI and Seed-to-Voxel analyses were carried out and revealed functional connectivity deficits in patients within all the networks investigated demonstrating the possible negative effect of chemotherapy in cognitive functions in SCLC populations.

    We tested the hypothesis that expression of microRNAs (miRNAs) in cancer tissue can predict effectiveness of bevacizumab added to capecitabine and oxaliplatin (CAPEOX) in patients with metastatic colorectal cancer (mCRC). Patients with mCRC treated with first line CAPEOX and bevacizumab (CAPEOXBEV): screening (n = 212) and validation (n = 121) cohorts, or CAPEOX alone: control cohort (n = 127), were identified retrospectively and archival primary tumor samples were collected. Expression of 754 miRNAs was analyzed in the screening cohort using polymerase chain reaction (PCR) arrays and expression levels were related to time to disease progression (TTP) and overall survival (OS). Significant miRNAs from the screening study were analyzed in all three cohorts using custom PCR arrays. In situ hybridization (ISH) was done for selected miRNAs. In the screening study, 26 miRNAs were significantly correlated with outcome in multivariate analyses. Twenty-two miRNAs were selected for further study. Higher miR-664-3p expression and lower miR-455-5p expression were predictive of improved outcome in the CAPEOXBEV cohorts and showed a significant interaction with bevacizumab effectiveness. The effects were strongest for OS. Both miRNAs showed high expression in stromal cells. Higher expression of miR-196b-5p and miR-592 predicted improved outcome regardless of bevacizumab treatment, with similar effect estimates in all three cohorts. We have identified potentially predictive miRNAs for bevacizumab effectiveness and additional miRNAs that could be related to chemotherapy effectiveness or prognosis in patients with mCRC. Our findings need further validation in large cohorts, preferably from completed randomized trials.

    Full Text Available Background. To report on the use and feasibility of a multimodality approach using concomitant radiotherapy and chemotherapy in patients with high-risk nonmelanoma skin carcinoma (NMSC of the head and neck. Methods. Records of patients with NMSC of the head and neck who received concomitant CRT at the University of North Carolina between 2001 and 2007 were reviewed. Results. Fifteen identified patients had at least one of the following high-risk factors: T4 disease (93%, unresectability (60%, regional nodal involvement (40%, and/or recurrence (47%. Ten patients were treated in the definitive setting and five in the postoperative setting. Platinum based chemotherapy was given in 14 (93% patients. Ten of fifteen (67% patients completed all planned chemotherapy treatments, and thirteen patients (87% completed at least 80% of planned chemotherapy. Mild radiation dermatitis occurred in all patients and reached grade 3 in 13% of patients. No patients experienced grade 4 or 5 toxicity. With a median followup of 31 months in surviving patients, the 2-year actuarial locoregional control and relapse-free survival were 79% and 49%, respectively. Conclusions. Definitive or postoperative chemoradiotherapy for patients with locally advanced or regionally metastasized NMSC of the head and neck appears feasible with acceptable toxicities and favorable locoregional control.

    Full Text Available Abstract Background Most cervical cancer patients with pelvic recurrent or persistent disease are not candidates for exenteration, therefore, they only receive palliative chemotherapy. Here we report the results of a novel treatment modality for these patients pre-exenterative chemotherapy- under the rational that the shrinking of the pelvic tumor would allow its resection. Methods Patients with recurrent or persistent disease and no evidence of systemic disease, considered not be candidates for pelvic exenteration because of the extent of pelvic tumor, received 3-courses of platinum-based chemotherapy. Response was evaluated by CT scan and bimanual pelvic examination; however the decision to perform exenteration relied on the physical findings. Toxicity to chemotherapy was evaluated with standard criteria. Survival was analyzed with the Kaplan-Meier method. Results Seventeen patients were studied. The median number of chemotherapy courses was 4. There were 9 patients who responded to chemotherapy, evaluated by bimanual examination and underwent pelvic exenteration. Four of them had pathological complete response. Eight patients did not respond and were not subjected to surgery. One patient died due to exenteration complications. At a median follow-up of 11 months, the median survival for the whole group was 11 months, 3 months in the non-operated and 32 months in those subjected to exenteration. Conclusion Pre-exenterative chemotherapy is an alternative for cervical cancer patients that are no candidates for exenteration because of the extent of the pelvic disease. Its place in the management of recurrent disease needs to be investigated in randomized studies, however, its value for offering long-term survival in some of these patients with no other option than palliative care must be stressed.

    Few treatments with a distinct mechanism of action are available for patients with platinum-refractory advanced or metastatic urothelial carcinoma. We assessed the efficacy and safety of treatment with docetaxel plus either ramucirumab-a human IgG1 VEGFR-2 antagonist-or placebo in this patient population. We did a randomised, double-blind, phase 3 trial in patients with advanced or metastatic urothelial carcinoma who progressed during or after platinum-based chemotherapy. Patients were enrolled from 124 sites in 23 countries. Previous treatment with one immune-checkpoint inhibitor was permitted. Patients were randomised (1:1) using an interactive web response system to receive intravenous docetaxel 75 mg/m(2) plus either intravenous ramucirumab 10 mg/kg or matching placebo on day 1 of repeating 21-day cycles, until disease progression or other discontinuation criteria were met. The primary endpoint was investigator-assessed progression-free survival, analysed by intention-to-treat in the first 437 randomised patients. This study is registered with ClinicalTrials.gov, number NCT02426125. Between July, 2015, and April, 2017, 530 patients were randomly allocated either ramucirumab plus docetaxel (n=263) or placebo plus docetaxel (n=267). Progression-free survival was prolonged significantly in patients allocated ramucirumab plus docetaxel versus placebo plus docetaxel (median 4·07 months [95% CI 2·96-4·47] vs 2·76 months [2·60-2·96]; hazard ratio [HR] 0·757, 95% CI 0·607-0·943; p=0·0118). A blinded independent central analysis was consistent with these results. An objective response was achieved by 53 (24·5%, 95% CI 18·8-30·3) of 216 patients allocated ramucirumab and 31 (14·0%, 9·4-18·6) of 221 assigned placebo. The most frequently reported treatment-emergent adverse events, regardless of causality, in either treatment group (any grade) were fatigue, alopecia, diarrhoea, decreased appetite, and nausea. These events occurred predominantly at grade 1

    Full Text Available Abstract Background Tipranavir (TPV is a recently approved nonpeptidic protease inhibitor (PI of HIV-1 and has been indicated for those infected with PIs-resistant HIV-1. However, in clinical practice, whether the HIV-1 from the patients with virological failure to the regimens containing first-line PIs remains susceptible to TPV/r may be questionable. Methods To assess the resistance levels to TPV of HIV-1 from patients with treatment failure to first-line PIs, patients who experienced virological failure were tested for genotypic resistance of HIV-1 since August 2006 in National Taiwan University Hospital. Patients were enrolled for this analysis if their failed regimens contained > 12 weeks of atazanavir or lopinavir/ritonavir (defined as ATV group and LPV/r group, respectively, but were excluded if they experienced both or other PIs. The levels of genotypic resistance to TPV/r were determined by TPV mutation score. Results Till May 2008, 21 subjects in ATV group and 20 subjects in LPV/r group were enrolled. The TPV mutation scores in subjects in LPV/r group were significantly higher than these in ATV group (median, 3 vs 1, P = 0.007. 95.2% subjects in ATV group and only 45% subjects in LPV/r group had an estimated maximal virological response to TPV/r (P Conclusion Cross-resistance from first-line PIs may impede the effectiveness of TPV/r-containing salvage therapy. TPV/r should be used cautiously for patients with virological failure to LPV/r especially long duration of exposure.

    Combination antiretroviral therapy (ART) has improved in efficacy, durability and tolerability. Virological efficacy studies in India are limited. We determined incidence and predictors of virological failure among patients initiating first-line ART and described virological resuppression after confirmed failure, with the goal of informing national policy. Therapy-naïve patients initiated on first-line ART as per national guidelines were monitored every 3 months for adherence and virological response over 2 years. Genotyping on baseline samples was performed to assess primary drug resistance. Multivariate Cox regression analysis was used to assess predictors of virological failure. Virological failure rate among 599 eligible patients was 10.7 failures per 100 person-years. Cumulative failure incidence was 13.2% in the first year and 16.5% over 2 years. Patients initiated on tenofovir had a significantly lower rate of virological failure than those on stavudine or zidovudine (6.7 vs. 11.9 failures per 100 person-years, P = 0.013). Virological failure was independently associated with age <40 years, mean adherence <95%, non-tenofovir-containing regimens and presence of primary drug resistance. In a subset of 311 patients who were reassessed after treatment failure, 19% (11/58) patients resuppressed their viral load to <400 copies/ml after confirmed virological failure. Our results support the inclusion of tenofovir as first-line ART in resource-limited settings and a role for regular adherence counselling and virological monitoring for enhanced treatment success. Detection of early virological failure should provide an opportunity to augment adherence counselling and repeat viral load testing before therapy switch is considered. © 2015 John Wiley & Sons Ltd.

    Full Text Available Metastatic carcinoma of unknown primary (CUP has a very poor prognosis, and no standard first-line therapy currently exists. Here, we report the results of a phase II study utilizing a combination of gemcitabine and irinotecan as first-line therapy. Treatment was with gemcitabine 1000 mg/m(2 and irinotecan 75 mg/m(2 weekly times four on a six week cycle (Cohort I. Due to excessive toxicity, the dose and schedule were modified as follows: gemcitabine 750 mg/m(2 and irinotecan 75 mg/m(2 given weekly times three on a four week cycle (Cohort II. The primary endpoint was the confirmed response rate (CR + PR. Secondary endpoints consisted of adverse events based upon the presence or absence of the UDP glucuronosyltransferase 1 family, polypeptide A1*28 (UGT1A1*28 polymorphism, time to progression, and overall survival. Thirty-one patients were enrolled with a median age of 63 (range: 38-94, and 26 patients were evaluable for efficacy. Significant toxicity was observed in Cohort 1, characterized by 50% (7/14 patients experiencing a grade 4+ adverse event, but not in cohort II. The confirmed response rate including patients from both cohorts was 12% (95% CI: 2-30%, which did not meet the criteria for continued enrollment. Overall median survival was 7.2 months (95% CI: 4.0 to 11.6 for the entire cohort but notably longer in cohort II than in cohort I (9.3 months (95% CI: 4.1 to 12.1 versus 4.0 months (95% CI: 2.2 to 15.6. Gemcitabine and irinotecan is not an active combination when used as first line therapy in patients with metastatic carcinoma of unknown primary. Efforts into developing novel diagnostic and therapeutic approaches remain important for improving the outlook for this heterogeneous group of patients.ClinicalTrials.gov NCT00066781.

    Full Text Available Introduction: First-line antiretroviral therapy (ART failure often results from the development of resistance-associated mutations (RAMs. Three patterns, including thymidine analogue mutations (TAMs, 69 Insertion (69Ins and the Q151M complex, are associated with resistance to multiple-nucleoside reverse transcriptase inhibitors (NRTIs and may compromise treatment options for second-line ART. Methods: We investigated patterns and factors associated with multi-NRTI RAMs at first-line failure in patients from The TREAT Asia Studies to Evaluate Resistance – Monitoring study (TASER-M, and evaluated their impact on virological responses at 12 months after switching to second-line ART. RAMs were compared with the IAS-USA 2013 mutations list. We defined multi-NRTI RAMs as the presence of either Q151M; 69Ins; ≥2 TAMs; or M184V+≥1 TAM. Virological suppression was defined as viral load (VL 2 years (OR=6.25, 95% CI [2.39–16.36], p<0.001. Among 87/105 patients with available VL at 12 months after switch to second-line ART, virological suppression was achieved in 85%. The median genotypic susceptibility score (GSS for the second-line regimen was 2.00. Patients with ART adherence ≥95% were more likely to be virologically suppressed (OR=9.33, 95% CI (2.43–35.81, p=0.001. Measures of patient resistance to second-line ART, including the GSS, were not significantly associated with virological outcome. Conclusions: Multi-NRTI RAMs at first-line failure were associated with low CD4 level and longer duration of ART. With many patients switching to highly susceptible regimens, good adherence was still crucial in achieving virological response. This emphasizes the importance of continued adherence counselling well into second-line therapy.

    Fluconazole is a standard first-line therapy for candidemia/invasive candidiasis (C/IC), based on its efficacy, safety profile, and comparatively low acquisition cost. However, little is known about the total costs associated with fluconazole treatment for this indication, particularly in cases of clinical failure. The aim of this study was to examine overall costs, resource use, and treatment outcomes associated with fluconazole as first-line therapy for invasive Candida infections in the United States. A retrospective analysis of data from a US hospital-based (>500 hospitals), service-level database was performed. All patients aged >16 years with primary or secondary International Classification of Diseases, Ninth Revision, Clinical Modification codes for IC or septicemia, receiving intravenous fluconazole treatment, and discharged between October 1, 2004 and September 30, 2005 were selected. Costs and resource use were calculated from the start of antifungal therapy until discharge. Two groups were analyzed: patients who received fluconazole only and those who required a second-line antifungal. Separate analyses for the survivor subpopulations were also conducted. A total of 7170 patients met the inclusion criteria; 21.2% required an additional antifungal agent. Overall mortality was 27.1%, and total mean treatment cost for all patients was $44,482 (in 2005 US dollars). Patients treated with fluconazole alone incurred mean costs of $36,319. Mean hospital and intensive care unit stays in the fluconazole monotherapy group were 17.9 days and 7.1 days, respectively. Patients requiring additional therapy had a mortality rate of 34.5% and a mean treatment cost of $76,329; in this group, the mean hospital and intensive care unit stays were 31.7 days and 14.8 days, respectively. The overall resource use associated with fluconazole as first-line treatment for C/IC was high, especially in patients who required additional antifungal therapy. Future studies should examine

    Studies concerning the eradication of Helicobacter pylori have resulted in a proliferation of meta-analyses. To date, there are 303 meta-analyses cited in PubMed, 113 dealing with the therapy of the infection. A chronological analysis of the results of meta-analyses performed between 1998 and 2010 shows that first-line standard triple therapies achieved eradication rates on an intention-to-treat basis of around 80%; prolonging treatment to 14, but not 10 d should improve the results.

    Raynaud's phenomenon is a transient paroxysmal vasomotor phenomenon affecting the extremities including manifestations of ischemia. It is a common phenomenon in the general population. In a routine clinical situation, the first step is to differentiate Raynaud's disease from a secondary Raynaud's phenomenon, the latter requiring complementary investigations. We report here the case of an 80-year-old woman who presented a secondary Raynaud's phenomenon. First-line investigations remained negative. A mammography was performed and revealed breast cancer. Raynaud's phenomenon disappeared after treatment of the breast carcinoma and did not recur during the 2-year follow-up.

Virological suppression was defined as viral load (VL) Thailand, Hong Kong, Indonesia, Malaysia and Philippines were included. There were 97/105 (92%) patients harbouring ≥1 RAMs at first-line failure, 39/105 with multi-NRTI RAMs: six with Q151M; 24 with ≥2 TAMs; and 32 with M184V+≥1 TAM. Factors associated with multi-NRTI RAMs were CD4 ≤200 cells/µL at genotyping (OR=4.43, 95% CI [1.59–12.37], p=0.004) and ART duration >2 years (OR=6.25, 95% CI [2.39–16.36], p<0.001).

    As a specific variation of chemotherapy-induced nausea and vomiting, anticipatory nausea and vomiting (ANV) appears particularly linked to psychological processes. The three predominant factors related to ANV are classical conditioning; demographic and treatment-related factors; and anxiety or negative expectancies. Laboratory models have provided some support for these underlying mechanisms for ANV. ANV may be treated with medical or pharmacological interventions, including benzodiazepines and other psychotropic medications. However, behavioral treatments, including systematic desensitization, remain first line options for addressing ANV. Some complementary treatment approaches have shown promise in reducing ANV symptoms. Additional research into these approaches is needed. This review will address the underlying models of ANV and provide a discussion of these various treatment options.

    ITSI as a first-line therapy in uremia patients with SSNHL offers a valid and safe treatment compared with intravenous systemic steroid treatment. A specific pathophysiology caused by possible sodium pump paralysis may be explained for uremia patients with SSNHL. To compare the efficacy of intratympanic steroid injection (ITSI) with that of systemic intravenous steroids as a first-line therapy in uremia patients with sudden sensorineural hearing loss (SSNHL). A total of 23 consecutive uremia patients with SSNHL were enrolled in this study. Patients were divided into two groups: the ITSI group (n = 15) and the non-ITSI group (n = 8), in which patients received intravenous systemic steroid treatment. The two groups were homogeneous in all respects. The hearing improvement and relative gain were statistically significant between the two groups. The value of hearing gain (ΔPTA = PTA pre - PTA post) in the ITSI group and the non-ITSI group was 24.6 ± 16.4dB and 8.4 ± 19.3dB. The value of relative gain (ΔPTA/PTApre) in the ITIS group and the non-ITSI group was 31.1 ± 22% and 9.4 ± 20.5%. In the ITSI group, 11 patients (73.3%) exhibited hearing recovery (ΔPTA > 10 dB).

    The optimal treatment approach for patients with mantle cell lymphoma (MCL) is not well defined. Intensive therapeutic regimens result in high response rates and prolonged progression-free survival but at the expense of significant toxicity. We report here our results of the administration of rituximab plus chlorambucil (R-Chl) as first line treatment in patients with MCL. Twenty consecutively diagnosed patients were treated with this combination in which an induction and a maintenance arm were included. During induction, rituximab was administered at a dose of 375 mg/m(2) on day 1, while chlorambucil was given afterward at a dose of 10 mg/day for 10 consecutive days for eight cycles and then as a single agent for an additional four cycles. Maintenance consisted of rituximab administration every 2 months for 1 year. Most patients had indolent disease features such as a low mantle-cell international prognostic index (MIPI) score. The overall response rate was 95% (90% CR, 5% PR). Among patients in CR, 78% presented a molecular remission. The 3-year progression-free survival was 89%. There were no serious side effects. These results show that the R-Chl combination could be an effective therapeutic option as first line treatment in MCL, especially for patients with indolent disease characteristics.

    Bleeding after cardiac surgery requiring surgical reexploration and blood component transfusion is associated with increased morbidity and mortality. Although prothrombin complex concentrate (PCC) has been used satisfactorily in bleeding disorders, studies on its efficacy and safety after cardiopulmonary bypass are limited. Between January 2005 and December 2013, 3454 consecutive cardiac surgery patients were included in an observational study aimed at investigating the efficacy and safety of PCC as first-line coagulopathy treatment as a replacement for fresh frozen plasma (FFP). Starting in January 2012, PCC was introduced as solely first-line treatment for bleeding following cardiac surgery. After one-to-one propensity score-matched analysis, 225 pairs of patients receiving PCC (median dose 1500 IU) and FFP (median dose 2 U) were included. The use of PCC was associated with significantly decreased 24-h post-operative blood loss (836 ± 1226 vs. 935 ± 583 ml, p surgery setting, the use of PCC compared with FFP was associated with decreased post-operative blood loss and RBC transfusion requirements. However, PCC administration may be associated with a higher risk of post-operative AKI.

    Due to the unavailability of horse antithymocyte globulin (ATG) in many markets worldwide, patients with severe aplastic anemia (SAA) are limited to the use of rabbit ATG. We aimed to analyze hematologic response and overall survival (OS) of Asian patients treated with rabbit ATG as first-line therapy of SAA. We retrospectively reviewed the medical records of 97 consecutive patients who received rabbit ATG as first-line treatment of SAA from 2006 to 2012 at centers in four Asian countries. The primary endpoint was 6- and 12-month overall response rates (ORR) for patients receiving rabbit ATG within the recommended dose range (2.5-3.75 mg/kg/day). Secondary endpoints included ORR in patients receiving any dose of rabbit ATG and 2-year OS. For patients who received rabbit ATG within the recommended dose range, 6- and 12-month ORRs were 17.4 and 63.6 %, respectively. For patients who received any dose of rabbit ATG, 6- and 12-month ORRs were 24.3 and 68.6 %, respectively. The 2-year OS rate was 86.3 %. Rabbit ATG is effective for treatment of SAA in Asian patients. The 12-month ORR and 2-year OS with rabbit ATG were comparable to historical results obtained with horse ATG.

    To assess the prevalence of metabolic syndrome (MetS) among patients in rural Lesotho who are taking first-line antiretroviral therapy (ART) containing either zidovudine or tenofovir disoproxil. Cross-sectional survey in 10 facilities in Lesotho among adult (≥16 years) patients on non-nucleoside reverse transcriptase inhibitor (NNRTI)-based first-line ART for ≥6 months. MetS was defined according to the International Diabetes Federation criteria. Among 1166 patients (65.8% female), 22.2% (95% CI: 19.3-25.3) of women and 6.3% (4.1-9.1) of men met the IDF definition of MetS (P < 0.001). In both sexes, there was no significant difference in MetS prevalence between NNRTIs. However, in women taking zidovudine as nucleoside reverse transcriptase inhibitor (NRTI), MetS prevalence was 27.9%, vs. 18.8% in those taking tenofovir. In the multivariate logistic regression allowing for socio-demographic and clinical covariates, ART containing zidovudine was associated with MetS in women (aOR 2.17 (1.46-3.22), P < 0.001) but not in men. In this study, taking ART containing zidovudine instead of tenofovir disoproxil was an independent predictor of MetS in women but not in men. This finding endorses WHO's recommendation of tenofovir as preferred NRTI. © 2017 John Wiley & Sons Ltd.

    Full Text Available Objective: Gemcitabine and platinum-based compounds represent the new standard combination therapy for bladder cancer. In this study, we evaluate the efficacy and safety of gemcitabine and carboplatin followed sequentially by paclitaxel in 27 patients with advanced transitional cell carcinoma.Methods: This phase II multicentre study was based on the doublet gemcitabine 800 mg/m2 and carboplatin area under the concentration-time curve 2 on days 1 and 8 every 21 days for 4 cycles, followed sequentially by paclitaxel 60 mg/m2/w for 12 consecutive weeks. The disease was assessed after each sequence.Results: Primary tumor was localized in the bladder and renal pelvis in 25 and 2 patients, respectively. Twenty patients completed all 4 cycles of the gemcitabine and carboplatin sequence. Mean number of cycles was 3.5 (range 1 to 4. Toxicities were mainly hematologic, including Grade 3 neutropenia and anemia in 3 patients. Objective response was noted in 11 pts (40.7%, including 1 complete response (CR and 10 partial responses (PR. Three patients had stable disease and 11 progressed. Among the 20 patients, 14 received the second sequence. Mean number of paclitaxel injections was 7 (range 2 to 12. Toxicities were limited to diarrhea and neurotoxicity in 1 patient each. Objective response was documented in 6 patients (30% (3 CR and 3 PR, including the improvement of PR into CR in 2 patients. Median duration of response was 6 months. After a median follow-up of 7 months, 21 patients died and 6 remained alive, including 2 who maintained CR and 1 PR.Sixteen patients had locally advanced disease and 11 had metastatic disease, better prognostic was noticed with patients with locally advanced disease.Conclusion: the sequential approach of treatment for advanced urothelial cancer using gemcitabine and carboplatine followed by paclitaxel seems to be a safer alternative to the combined triplet, but due to the limited number of patients this study failed to improve

    Full Text Available Ovarian carcinoma (OC is the most lethal gynecological malignancy. Despite the advances in the treatment of OC with combinatorial regimens, including surgery and platinum-based chemotherapy, patients generally exhibit poor prognosis due to high chemotherapy resistance. Herein, we tested the hypothesis that DNA damage response (DDR pathways are involved in resistance of OC patients to platinum chemotherapy. Selected DDR signals were evaluated in two human ovarian carcinoma cell lines, one sensitive (A2780 and one resistant (A2780/C30 to platinum treatment as well as in peripheral blood mononuclear cells (PBMCs from OC patients, sensitive (n = 7 or resistant (n = 4 to subsequent chemotherapy. PBMCs from healthy volunteers (n = 9 were studied in parallel. DNA damage was evaluated by immunofluorescence γH2AX staining and comet assay. Higher levels of intrinsic DNA damage were found in A2780 than in A2780/C30 cells. Moreover, the intrinsic DNA damage levels were significantly higher in OC patients relative to healthy volunteers, as well as in platinum-sensitive patients relative to platinum-resistant ones (all P<0.05. Following carboplatin treatment, A2780 cells showed lower DNA repair efficiency than A2780/C30 cells. Also, following carboplatin treatment of PBMCs ex vivo, the DNA repair efficiency was significantly higher in healthy volunteers than in platinum-resistant patients and lowest in platinum-sensitive ones (t1/2 for loss of γH2AX foci: 2.7±0.5h, 8.8±1.9h and 15.4±3.2h, respectively; using comet assay, t1/2 of platinum-induced damage repair: 4.8±1.4h, 12.9±1.9h and 21.4±2.6h, respectively; all P<0.03. Additionally, the carboplatin-induced apoptosis rate was higher in A2780 than in A2780/C30 cells. In PBMCs, apoptosis rates were inversely correlated with DNA repair efficiencies of these cells, being significantly higher in platinum-sensitive than in platinum-resistant patients and lowest in healthy volunteers (all P<0.05. We conclude

    Full Text Available Objective: To explore the clinical efficacy and safety of rituximab combined with chemotherapy and single chemotherapy for diffuse large B cell lymphoma (DLBCL. Methods: A total of 97 patients with DLBCL were selected. Patients treated by single chemotherapy were designed as control group, while those by rituximab combined with chemotherapy as observational group. All patients were treated for at least 4 cycles. The short-term and long-term efficacy and related adverse reactions of 2 groups were observed. Results: The rate of complete remission (CR in observational group was significantly higher than in control group (χ2=4.6589, P=0.0309. However, there was no significant difference in objective remission rate (ORR between 2 groups (P=0.3651. The rates of 3-year overall survival (OS, progression-free survival (PFS and disease-free survival (DFS were 80.30% (53/66, 69.70% (46/66 and 59.09% (39/66 in observational group, and 61.29% (19/31, 58.06% (18/31 and 58.06% (18/31 in control group, respectively. The OS in observational group was significantly longer than in control group (P=0.035. However, there was no significant difference in PFS, DFS and rate adverse reactions between 2 groups (P=0.089; P=0.438; χ2=0.1562, P=0.6927. Conclusion: Rituximab combined with chemotherapy can improve the efficacy of DLBCL without increasing the adverse reactions, which can be used as the first-line treatment for DLBCL, thus deserving to be widely applied in clinic.

    Background: Platinum-based therapy (PBT) is the standard therapy for recurrent and/or metastatic head and neck cancer (HNC), but the incidence of recurrence remains high. This study evaluates the efficacy and tolerability of capecitabine as palliative monotherapy for recurrent HNC previously treated with PBT. Methods: Patients aged 18–75 years, with Eastern Cooperative Oncology Group performance status 0–2, squamous HNC with locoregional and/or metastatic recurrence previously treated with PBT and adequate organ functions, were included. Capecitabine (1.250 mg m−2 BID) was administered on days 1–14 every 21 days for at least two cycles. Results: A total of 40 male patients with a median age of 58 years were analysed. All patients received a median number of four cycles of capecitabine (range: 1–9) and the median relative dose intensity was 91%. Seven patients were not evaluable for response. Overall response rate was 24.2%. Median time to progression and overall survival were 4.8 and 7.3 months, respectively. Haematological adverse events (AEs) grade 3/4 were reported in six patients. Most common grade 3/4 non-haematological AEs were asthenia (12.5%), palmar-plantar eritrodisestesia (10%), mucositis (10%), dysphagia (10%) and diarrhoea (7.5%). Conclusions: Capecitabine seems to be an active, feasible and well-tolerated mode of palliative treatment for advanced HNC patients who have previously received PBT schedules. PMID:20485287

    Full Text Available Stem cell transplantation forms an integral part of the treatment for multiple myeloma. This paper reviews the current role of transplantation and the progress that has been made in order to optimize the success of this therapy. Effective induction chemotherapy is important and a combination regimen incorporating the novel agent bortezomib is now favorable. Adequate induction is a crucial adjunct to stem cell transplantation and in some cases may potentially postpone the need for transplant. Different conditioning agents prior to transplantation have been explored: high-dose melphalan is most commonly used and bortezomib is a promising additional agent. There is no well-defined superior transplantation protocol but single or tandem autologous stem cell transplantations are those most commonly used, with allogeneic transplantation only used in clinical trials. The appropriate timing of transplantation in the treatment plan is a matter of debate. Consolidation and maintenance chemotherapies, particularly thalidomide and bortezomib, aim to improve and prolong disease response to transplantation and delay recurrence. Prognostic factors for the outcome of stem cell transplant in myeloma have been highlighted. Despite good responses to chemotherapy and transplantation, the problem of disease recurrence persists. Thus, there is still much room for improvement. Treatments which harness the graft-versus-myeloma effect may offer a potential cure for this disease. Trials of novel agents are underway, including targeted therapies for specific antigens such as vaccines and monoclonal antibodies.

    2016-01-01

    Objectives Hypertension is well established as a major risk factor for cardiovascular disease. Although there is undeniable evidence to support the beneficial effects of antihypertensive therapy on morbidity and mortality, adequate blood pressure management still remains suboptimal. Research into the treatment of hypertension has produced a multitude of drug classes with different efficacy profiles. These agents include β-blockers, diuretics, ACE inhibitors, angiotensin receptor blockers and calcium channel blockers. One of the oldest groups of antihypertensives, the calcium channel blockers are a heterogeneous group of medications. Methods This review paper will focus on amlodipine, a dihydropyridine calcium channel blockers, which has been widely used for 2 decades. Results Amlodipine has good efficacy and safety, in addition to strong evidence from large randomised controlled trials for cardiovascular event reduction. Conclusions Amlodipine should be considered a first-line antihypertensive agent.

    Full Text Available Changes in the South African media and management environment have had distinct influences on especially small to medium-sized mainstream media enterprises (media SMEs which often have to compete with bigger media organisations for the same news stories. Moreover, these media organisations are commonly faced with unique challenges related to human and other resources. This situation adds to the importance of effective and efficient management practices at these media sites. The management practices of first-line news managers in media SMEs are qualitatively and quantitatively evaluated in this paper by considering six managerial competencies found in general management theory. These competencies relate to communication, planning and administration, teamwork; strategic action, global awareness and self-management.

    Full Text Available Abstract Objective: To explore the efficacy and safety of S-1 plus oxaliplatin versus S-1 plus cisplatin as the first-line treatment for elderly patients with advanced gastric cancer. Methods: A total of 60 patients with advanced gastric cancer admitted in Xi’an Yanliang Railway Hospital from Jan., 2011 to Oct., 2013 were selected as study objects and randomly divided into 2 groups: S1 plus oxaliplatin group (SOX group, 30 cases and S1 plus cisplatin group (SP group, 30 cases. SOX group were given intravenous drip of 130 mg/m2 oxaliplatin for 2 h on d1. And S-1 was also given according to body surface area: body surface area <1.25 m2, 40 mg once; 1.25-1.5 m2, 60 mg once; >1.5, 28 d as 1 cycle. SP group was administered with intravenous drip of 25 mg/m2 cisplatin during d1-d3. Treatment was discontinued until the occurrence of disease progression or patients’ intolerance to chemotherapy. Results: SOX group was non-inferior to SP group in overall response rate (ORR (53.3% vs. 43.3%, disease control rate (DCR (83.3% vs. 80.0%, median progression-free survival (PFS (7.0 vs. 6.0 months and median overall survival (OS (11.0 vs. 10.5 months. However, the difference was statistical significant in the rate of increased KPS score (86.7% vs. 46.7%, χ2=10.800, P=0.001 and the rate of increased FACT-G score (73.3% vs. 36.7%, χ2=8.148, P=0.004. The main toxic and side effects of two groups was hematological toxicity. There was no degree III-IV toxic and side effects occurring in non hematological toxicity in two groups. The main toxic effect was peripheral neuritis in SOX group, and nausea and vomiting and renal dysfunction in SP group, and there were statistical differences in the above toxic and side effects between two groups (P<0.05. Conclusion: SOX regimen is as safe and effective as SP regimen for elderly patients with advanced gastric cancer, with better quality of life and less toxic and side effects.

    Full Text Available Abstract Background Docetaxel is the standard first-line agent for the treatment of androgen-independent prostate cancer (AIPC. The combination of docetaxel with molecularly targeted therapies may offer the potential to increase the efficacy and decrease the toxicity of cytotoxic chemotherapy for prostate cancer. Previous studies demonstrate activation of the human epidermal growth factor receptor (EGFR in prostate cancer. Erlotinib is a specific inhibitor of the tyrosine-kinase activity of EGFR. The goal of this study is to determine the anti-cancer activity docetaxel combined with erlotinib for the treatment of elderly subjects with AIPC. Methods This is a multi-institutional Phase II study in patients with histologically confirmed adenocarcinoma of the prostate and age ≥ 65 years. Patients were requred to have progressive disease despite androgen-deprivation therapy as determined by: (1 measurable lesions on cross-sectional imaging; (2 metastatic disease by radionucleotide bone imaging; or (3 elevated prostate specific antigen (PSA. Treatment cycles consisted of docetaxel 60 mg/m2 IV on day 1 and erlotinib 150 mg PO days 1–21. Patients with responding or stable disease after 9 cycles were eligible to continue on erlotinib alone as maintenance therapy. Results Characteristics of 22 patients enrolled included: median age 73.5 years (range, 65–80; median Karnofsky Performance Status 90 (range 70–100; median hemoglobin 12.1 g/dl (range, 10.0–14.3; median PSA 218.3 ng/ml (range, 9–5754. A median of 6 treatment cycles were delivered per patient (range 1–17. No objective responses were observed in 8 patients with measurable lesions (0%, 95% CI 0–31%. Bone scan improvement and PSA decline was seen in 1 patient (5%, 95% CI 0.1–25%. Five of 22 patients experienced ≥ 50 % decline in PSA (23%, 95% CI 8–45%.

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

    Although core needle biopsy was introduced as a diagnostic alternative to fine-needle aspiration, the utility and safety of core needle biopsy for thyroid nodules in a large population has yet to be studied comprehensively. We evaluate core needle biopsy yields on a large-scale basis to investigate its potential in the preliminary diagnosis of thyroid nodules. Between March 2005 and December 2013, 2448 initially detected thyroid nodules from 2120 consecutive patients who underwent core needle biopsy were retrospectively evaluated. Of these, 72 thyroid nodules from 63 patients were excluded due to prior fine-needle aspiration attempts. The inconclusive and conclusive result rates, diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and unnecessary surgery rate of core needle biopsy were evaluated. With core needle biopsy as the first-line method, the inconclusive result rate was 11.9% (283/2376) and the conclusive result rate was 88.1% (2093/2376). The diagnostic accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of core needle biopsy for the diagnosis of malignancy were 96.7% (1160/1200), 89.7% (347/387), 100% (813/813), 100% (347/347), and 95.3% (813/853), respectively. There were no major complications and 12 minor complications. We have demonstrated that first-line use of core needle biopsy may well improve diagnostic accuracy in thyroid nodules, reducing inconclusive or false-negative results and unnecessary operations. Such benefits underscore the promising role of core needle biopsy in managing thyroid nodules and optimizing related surgical decision-making. © 2017 by American Journal of Neuroradiology.

    A combination of surgical and medical treatment is normally required for patients with septic arthritis. Antibiotics selected for use on these patients are normally based on tissue culture results. However, in sub-acute and chronic septic arthritis cases, the results of the culture are usually negative as a result of prior treatment. The present study will investigate the incidence of culture-negative septic arthritis and the outcomes based on the use of first-line drug antibiotics for the treatment of sub-acute and chronic septic arthritis. For the present study, the authors retrospectively reviewed medical records of surgically treated septic arthritis cases over the past 10 years at Siriraj Hospital. The patient culture results, the antibiotics used, and the results of treatment were all recorded and analyzed. One hundredfifty-three septic arthritis patients were reviewed. Sixty-two patients were classified as having been diagnosed with either sub-acute or chronic septic arthritis. Thirty-six of 62 patients (58.1%) had a negative culture result. In the culture-positive patients, 42.3% had Streptococcus, 26.9% had Staphylococcus aureus, 11.5% had other gram positive bacteria, 15.4% had gram-negative bacteria, and 3.8% had tuberculus infection. In the culture-negative sub-acute and chronic group (36 of 62), 23 patients received Cefazolin, nine patients received Cloxacillin, and four patients received Clindamycin. Successful results were 69.9%, 66.7% and 75%, respectively. The present study reflects that the incidence ofculture-negative, sub-acute and chronic septic arthritis is approximately 58.1%. The first-line class of antibiotics remains the appropriate antibiotic choice for these patients because they are still effective for treatment of septic arthritis in up to 70% of all cases.

    Schreckenberger, Paul C; McAdam, Alexander J

    2015-10-01

    The first FDA-approved multiplex PCR panel for a large number of respiratory pathogens was introduced in 2008. Since then, other PCR panels for detection of several respiratory and gastrointestinal pathogens have been approved by the FDA and are commercially available, and more such panels are likely to become available. These assays detect 12 to 20 pathogens, and some include pathogens that typically cause different manifestations of infection, although they infect the same organ system. Some of these tests are labor-intensive, while others require little labor, and all of them are expensive, both for the laboratory and for the patient or insurer. They include a bundle of tests with limited or no options for selecting which tests will be performed. Laboratories and hospitals have adopted different strategies for offering these assays. Some have implemented strategies to limit the use of the tests, such as limiting the frequency with which patients can be tested, restricting testing to specific groups of patients (e.g., immunocompromised patients), or providing education to encourage the use of less expensive tests before using large multiplex panels. Others have offered these assays without limiting their use, either relying on the ordering provider to exercise good judgment or because such assays are thought to be appropriate for first-line diagnostic testing. In this Point-Counterpoint, Paul Schreckenberger of Loyola University Medical Center explains why his laboratory offers these assays without restriction. Alex McAdam of Boston's Children Hospital explains the concerns about the use of these assays as first-line tests and why some limitations on their use might be appropriate.

    Purpose: To analyze the impact of TP53 mutations on response to first-line tyrosine kinase inhibitors (TKI) in patients with EGFR-mutated non-small cell lung cancer (NSCLC).Experimental Design: 136 EGFR-mutated NSCLC patients receiving first-line TKIs were analyzed. TP53 mutations were evaluated in 123 patients in relation to disease control rate (DCR), objective response rate (ORR), progression-free survival (PFS), and overall survival (OS).Results:TP53 mutations were observed in 37 (30.1%), 10 (27.0%), 6 (16.2%), 9 (24.3%), and 12 (32.4%) patients in exons 5, 6, 7, and 8, respectively. DCR was 70% in TP53-mutated patients compared with 88% in TP53-wild type (wt) patients [relative risk, RR, of disease progression: 3.17 (95% CI, 1.21-8.48), P = 0.019]. In particular, a 42% DCR was observed in patients with TP53 exon 8 mutation versus 87% in exon 8 wt patients [RR of disease progression 9.6 (2.71-36.63), P TP53 exon 8 mutations compared with others (4.2 vs. 12.5, P = 0.058, and 16.2 vs. 32.3, P = 0.114, respectively); these differences became significant in the subgroup with EGFR exon 19 deletion (4.2 vs. 16.8, P TP53 mutations, especially exon 8 mutations, reduce responsiveness to TKIs and worsen prognosis in EGFR-mutated NSCLC patients, mainly those carrying exon 19 deletions.

    Background Estrogen receptor alpha(ER a)is the most important endocrine therapy responsiveness predictor for women with breast cancer.The accuracy of the prediction of the response to endocrine therapy was thought to be affected by involving the estrogen receptor coregulatory proteins and cross-talk between ER and other growth factor-signaling networks.Nuclear corepressor 1(NCOR1)is one of the ERa transcription repressor.The objective of the study is to investigate the expression of NCOR1 at the protein level and pursue its predictive value for breast cancer endocrine therapy.Methods In the present study,the level of expression of NCOR1 protein has been assessed by immunohistochemistry in 104 cases of invasive carcinoma of the breast.Associations between NCOR1 protein expression and different clinicopathological factors and survival were sought.Results It was found that NCOR1 was expressed at significantly higher levels in responsive patients treated with endocrine therapy as first-line treatment on relapse.Responsive patients also had a significantly longer post-relapse survival and overall survival.No NCOR1 expression difference was found between patient by age,tumor size,lymph node status,different histological grade groups and human epidermal growth factor receptor 2(HER2)status.Multivariate analysis showed that NCOR1 is an independent prognostic factor for over-all survival.Conclusions In breast cancer,NCOR1 protein expression level predicts response to endocrine therapy as first-line treatment for breast cancer patients on relapse and NCOR1 protein level assay may increase the accuracy in the endocrine treatment determination and,therefore,improving the patients survival.

    Because the prevalence of antibiotic resistance markedly increases with time worldwide, anti-H. pylori treatment is continuing to be a great challenge forsphysicians in clinical practice. The Real-world Practice & Expectation of Asia-Pacific Physicians and Patients in Helicobacter Pylori Eradication (REAP-HP) Survey demonstrated that the accepted minimal eradication rate of anti-H. pylori regimen in H. pylori-infected patients was 91%. The Kyoto Consensus Report on Helicobacter Pylori Gastritis also recommended that, within any region, only regimens which reliably produce eradication rates of ≥90% in that population should be used for empirical treatment. This article is aimed to review current first-line eradication regimens with a per-protocol eradication rate exceeding 90% in most geographic areas. In regions with low (≦15%) clarithromycin resistance, 14-day hybrid (or reverse hybrid), 10 ~ 14-day sequential, 7 ~ 14-day concomitant, 10 ~ 14-day bismuth quadruple or 14-day triple therapy can achieve a high eradication rate in the first-line treatment of H. pylori infection. However, in areas with high (>15%) clarithromycin resistance, standard triple therapy should be abandoned because of low eradication efficacy, and 14-day hybrid (or reverse hybrid), 10 ~ 14-day concomitant or 10 ~ 14-day bismuth quadruple therapy are the recommended regimens. If no recent data of local antibiotic resistances of H. pylori strains are available, universal high efficacy regimens such as 14-day hybrid (or reverse hybrid), concomitant or bismuth quadruple therapy can be adopted to meet the recommendation of consensus report and patients' expectation.

    We assessed the treatment outcomes on first-line antiretroviral therapy (ART), and factors associated with switching regimen in HIV-infected children treated through the universal coverage health program (UC) in Thailand. Children aged <15 years at ART initiation who had been receiving ART for at least 6 months between 2008 and 2014 through UC were included in the analysis. The Kaplan-Meier method was used to estimate immunological recovery (IMR), immunologic failure (IMF) and virologic failure (VF). Cox models were used to assess predictors of IMR and VF. Competing risk models were used to assess factors associated with switching to a second-line regimen, with death considered as a competing risk. A total of 4,120 children initiated ART at a median (IQR) age of 9.3 (5.8-12.0) years. The median duration of ART was 3.7 years with 17,950 person-years of follow up. 2,805 children achieved IMR and the probability of IMR increased to76% by 3 years after ART initiation. Among 1,054 children switched to second-line regimens; 84% had VF and 19% had IMF. The cumulative rate of switching regimen increased from 4% to 20% from 1 to 3 years after treatment. Children aged ≥ 12 years at ART initiation, starting with NNRTIs, and baseline CD4% < 10% had an increased risk of switching to second-line regimens. Children receiving ART through UC had good treatment outcomes, although a fifth required switching regimen by 3 years. Earlier treatment initiation and avoiding NNRTI first-line regimens in high risk children may prevent treatment failure.

    Background: The use of positron emission tomography with fluoro-deoxy-glucose (FDG PET) in Hodgkin's disease (HD) is continuing to expand worldwide, with response assessment after completion of therapy being its most widely utilized application. A positive scan has been associated with high relapse rates and disease progression. Methods: A decision analysis was performed to determine the long-term impact of FDG PET restaging both with and without computed tomography (CT) in terms of the 5-year progression-free survival (5yrPFS). Outcomes and utilities were based on published data. The first strategy involved CT restaging after first-line therapy, with or without subsequent FDG PET, while Second strategy used FDG PET scan alone. All positive test required histological examination. Upon histological confirmation of active lymphoma, patients were considered candidates for autologous transplantation and long-term outcomes were retrieved. The expected clinical benefit of the two strategies was calculated and depicted, along with the mean costs. One-way and two-way sensitivity analyses were performed to ensure the validity of the results. Results: CT restaging plus FDG PET when residual mass is detected, results in a 2% benefit at 5yrPFS at baseline compared to FDG PET-alone restaging and remains positive for a wide range of probabilities. This strategy reduces the average cost by Euro 1863 per patient, including costs of biopsy and autologous transplantation. Conclusion: A more conservative approach that includes CT restaging after first-line therapy and FDG PET scan only on residual mass, is the preferred strategy in HD. Furthermore it appears to confer the maximal diagnostic yield along with a substantial reduction in the mean cost.

    The use of induction chemotherapy (CT) is controversial. We compared the survival of head and neck cancer patients receiving docetaxel- or platinum-based induction CT before concomitant chemoradiotherapy (CCRT) with the survival of those receiving upfront CCRT alone. Data from the National Health Insurance and cancer registry databases in Taiwan were linked and analyzed. We enrolled patients who had head and neck cancer between January 1, 2002 and December 31, 2011. Follow-up was from the index date to December 31, 2013. We included head and neck patients diagnosed according to the International Classification of Diseases, Ninth Revision, Clinical Modification codes 140.0-148.9 who were aged >20 years, at American Joint Committee on Cancer clinical cancer stage III or IV, and receiving induction CT or platinum-based CCRT. The exclusion criteria were a cancer history before head and neck cancer diagnosis, distant metastasis, AJCC clinical cancer stage I or II, receipt of platinum and docetaxel before radiotherapy, an age induction CT for >8 weeks before RT, induction CT alone before RT, cetuximab use, adjuvant CT within 90 days after RT completion, an RT dose cancer surgery before RT, nasopharyngeal cancer, in situ carcinoma, sarcoma, and head and neck cancer recurrence. We enrolled 10,721 stage III-IV head and neck cancer patients, with a median follow-up of 4.18 years (interquartile range, 3.25 years). The CCRT (arm 1), docetaxel-based induction CT (arm 2), and platinum-based CCRT (arm 3; control arm) groups comprised 7968, 503, and 2232 patients, respectively. Arm 3 was used to investigate mortality risk after induction CT. After adjustment for age, sex, clinical stage, and comorbidities, the adjusted hazard ratios (aHRs) (95% confidence interval [CI]) for overall death were 1.37 (1.22-1.53) and 1.44 (1.36-1.52) in arms 2 and 3, respectively. In a disease-specific survival rate analysis, aHRs (95% CI) of head and neck cancer-related death were 1.29 (1

    Full Text Available Renal medullary carcinoma (RMC is a rare but aggressive malignancy affecting young individuals with sickle cell trait. Renal medullary carcinoma commonly presents with advanced or metastatic disease and is associated with a rapidly progressive clinical course and an extremely short overall survival measured in weeks to few months. Due to the rarity of RMC, there is no proven effective therapy and patients are often treated with platinum-based chemotherapy. We report near-complete radiological and pathological response in a patient treated with dose-dense MVAC (methotrexate, vinblastine, doxorubicin, and cisplatin chemotherapy. The patient underwent consolidation nephrectomy and retroperitoneal lymph node dissection and had a 16-month progression-free survival, one of the longest reported in patients with RMC.

    There is accumulating clinical evidence that chemotherapeutic agents induce neurological side effects, including memory deficits and mood disorders, in cancer patients who have undergone chemotherapeutic treatments. This review focuses on chemotherapy-induced neurodegeneration and hippocampal dysfunctions and related mechanisms as measured by in vivo and in vitro approaches. These investigations are helpful in determining how best to further explore the causal mechanisms of chemotherapy-induced neurological side effects and in providing direction for the future development of novel optimized chemotherapeutic agents.

    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 < 0.05) in comparison to NSCLC patients undergoing only chemotherapy (group I). Pulmonary rehabilitation of NSCLC patients undergoing first-line chemotherapy results in improvement of indicators of 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.

    To date, between 17% and 35% of patients with rheumatoid arthritis (RA) do not respond as expected to the initial biological therapy. The objective of this project is to recognize and weigh the attributes of biologic DMARD (bDMARD) to identify the most appropriate for each case, in the first lines of treatment of RA (after inadequate response to at least one synthetic DMARD or previous bDMARD). To recognize the possible attributes that could define the bDMARD, we performed a systematic search of the literature that recognized the possible attributes involving general aspects, pharmacology, efficacy, safety, management, and cost. Then a Delphi process was conducted with two rounds among a group of selected expert rheumatologists in the management of RA indicating the degree of agreement with the attributes identified in the literature. The project was completed between February and September 2015, indicating the degree of importance that was ascribed to each attribute. Two criteria were applied to determine the consistency of results: 1) based on the median and interquartile range; and 2) on the simultaneous compliance with mean, median, standard deviation, interquartile range and coefficient of variation. The agreement and final ratification of the expert panel were also determined. Eighty-three Spanish rheumatologists participated and completed both rounds of the Delphi process. In no case was the importance of the 77 attributes identified considered to be low; 75 of 77 (97.4%) were considered highly important and 76 of 77 (98.7%) were ratified. Fifteen attributes had the support of 100% of the working group. There was a high degree of agreement concerning the selected attributes. Fifteen of them had the support of 100% of the working group and could be considered the definition of the ideal bDMARD in the first lines of RA treatment.

    Hybrid therapy has recently attracted widespread attention. However, many issues require further exploration. For example, research in regions with high antibiotic resistance rates is limited, and the correlation between eradication efficacy and antibiotic resistance remains unclear. The aim of this study was to determine the efficacy, compliance, safety, and risk factors of hybrid therapy as first-line regimen in a region with high antibiotic resistance rates. This prospective study was conducted in a tertiary hospital between January 2014 and June 2015. A total of 196 patients with dyspepsia but without prior eradication therapy received hybrid regimen (esomeprazole 20 mg and amoxicillin 1000 mg twice daily for 14 days with the addition of clarithromycin 500 mg and tinidazole 500 mg twice daily for the final 7 days). All patients underwent Helicobacter pylori culture, antibiotic susceptibility testing and cytochrome P450 isoenzyme 2C19 polymorphism testing. Hybrid therapy achieved eradication rates of 77.0% (95% confidence interval (CI), 70.9-83.7%) in intention-to-treat (ITT), 83.9% (78.9-88.9%) in modified ITT and 86.0% (80.2-91.3%) in per-protocol analyses in a setting with high antibiotic resistance rates (amoxicillin 2.0%, clarithromycin 44.9%, metronidazole 67.3% and dual clarithromycin and metronidazole 33.3%). Adverse reactions occurred in 31.9% patients and 2.7% discontinued medications due to adverse reactions. Good compliance was achieved by 92.0%. Multivariate analyses identified clarithromycin resistance (odds ratio, 3.494; 95% CI, 1.237-9.869), metronidazole resistance (3.012; 1.013-12.054) and poor compliance (5.840; 1.126-30.296) as independent predictors of treatment failure. The eradication rate with dual clarithromycin and metronidazole resistance (70.2%) was markedly decreased compared to isolated clarithromycin resistance (87.5%), isolated metronidazole resistance (88.6%), or dual susceptibility (96.4%) (p = .014). Despite good compliance and

    The structural, elastic, electronic and optical properties of the platinum-based superconductor SrPt3P under pressure are investigated by the generalized gradient approximation with the Perdew-Burke-Ernzerhof exchange-correlation functional in the framework of density-functional theory. The calculated structural parameters (a, c) and the primitive cell volume V of SrPt3P at the ground state are in good agreement with the available experimental data and seem to be better than other calculated results. The pressure dependences of the elastic constants Cnolimitsij, bulk modulus B, shear modulus G, Young's modulus E and Poisson's ratio σ of SrPt3P are also obtained successfully. The computed elastic constants indicate that SrPt3P is mechanically stable up to 100 GPa. The obtained B/G is 2.56 at the ground state, indicating that SrPt3P behaves in a ductile manner. The ratio B/G also increases with growing pressures, indicating that the structure becomes more and more ductile. Even though SrPt3P is an ionic-covalent crystal, the obtained density of states shows that it has metallic characteristic. These conclusions can be further demonstrated by analysing the charge and Mulliken population. In addition, we have investigated the dielectric function and the loss function. It is found that the dielectric function in (E||x, E||y) is isotropic, whereas the directions (E||x, E||z) are anisotropic; the effect of pressure on the loss function of the deep ultraviolet region gradually increases as the pressure increases.

    Full Text Available The preparation and thorough characterization of a hybrid magnetic carrier system for the possible transport of activated platinum-based anticancer drugs, as demonstrated for cisplatin (cis-[Pt(NH32Cl2], CDDP, are described. The final functionalized mag/Au–LA–CDDP* system consists of maghemite/gold nanoparticles (mag/Au coated by lipoic acid (HLA; LA stands for deprotonated form of lipoic acid and functionalized by activated cisplatin in the form of cis-[Pt(NH32(H2O2]2+ (CDDP*. The relevant techniques (XPS, EDS, ICP-MS proved the incorporation of the platinum-containing species on the surface of the studied hybrid system. HRTEM, TEM and SEM images showed the nanoparticles as spherical with an average size of 12 nm, while their superparamagnetic feature was proven by 57Fe Mössbauer spectroscopy. In the case of mag/Au, mag/Au–HLA and mag/Au–LA–CDDP*, weaker magnetic interactions among the Fe3+ centers of maghemite, as compared to maghemite nanoparticles (mag, were detected, which can be associated with the non-covalent coating of the maghemite surface by gold. The pH and time-dependent stability of the mag/Au–LA–CDDP* system in different media, represented by acetate (pH 5.0, phosphate (pH 7.0 and carbonate (pH 9.0 buffers and connected with the release of the platinum-containing species, showed the ability of CDDP* to be released from the functionalized nanosystem.

    Sapoviruses are single stranded positive sense RNA viruses belonging to the family Caliciviridae. The virus is detected in different species including the human and the porcine species as an enteric pathogen causing asymptomatic to symptomatic enteritis. In this study, we report the development of a rapid real time qRT-PCR based on SYBR Green chemistry for the diagnosis of porcine sapovirus infection in swine. The method allows the detection of porcine sapoviruses and the quantification of the genomic copies present in stool samples. During its development, the diagnostic tool showed good correlation compared with the gold standard conventional RT-PCR and was ten-fold more sensitive. When the method was applied to field samples, porcine noroviruses from genogroup 2 genotype 11b were also detected. The method was also applied to swine samples from the Netherlands that were positive for PoSaV infection. Phylogenetic results obtained from the samples showed that PoSaV sequences were genetically related to the currently described genogroup III, to the proposed genogroup VII and also to the MI-QW19 sequence (close to the human SaV sequences). A rapid, sensitive, and reliable diagnosis method was developed for porcine sapovirus diagnosis. It correlated with the gold standard conventional RT-PCR. Specificity was good apart for genogroup 2 genotype 11b porcine noroviruses. As a first line screening diagnosis method, it allows a quicker and easier decision on doubtful samples.

    Febrile urinary tract infections (UTIs) often require the intravenous infusion of antibiotics and/or hospitalization. Acute pyelonephritis (AP) is one of the most severe forms of UTI, and the antibiotics we should use as the first line and the risk factors for treatment failure remain controversial. The objective of this study was to investigate the efficacy of i.v. antibiotics selected for the treatment of febrile AP and to examine the risk factors for antibiotic resistance. We set risk factors for antibiotic treatment failure such as age, sex, and the presence of underlying urinary tract disease. We classified all cases into 49 cases of complicated AP and 24 cases of uncomplicated AP according to the presence of underlying urinary tract diseases, and examined the characteristics of the patients and the efficacy of the antibiotics used in this study. We investigated risk factors which relate to initial treatment failure and the duration of antibiotic treatment. Initial antibiotic treatment failure was significantly correlated to C-reactive protein in complicated AP and to positive blood culture in uncomplicated AP. We revealed a significant correlation between the duration of the given antibiotics and diabetes mellitus or positive blood culture in uncomplicated AP, and tazobactam/piperacillin was significantly related to prolongation of antibiotic treatment in complicated AP. In conclusion, in this study, a positive blood culture was the representative risk factor that related to both initial treatment failure and longer duration of the given antibiotics in uncomplicated AP.

Pharmaceutical and administration costs were calculated in two scenarios: non-optimization and optimization of intravenous (IV) vials. The retrospective analysis of 66 patients from a Spanish 1,000 beds-hospital Rheumatology Clinic Service was used to obtain posology and weight data. The study time horizon was two years. Costs were expressed in 2013 euros. For an average 69kg-weighted patient the lowest cost corresponded to abatacept subcutaneous (SC ABA) (€21,028.09) in the scenario without IV vials optimization and infliximab (IFX) (€20,779.29) with optimization. Considering patients' weight in the scenario without IV vials optimization infliximab (IFX) was the least expensive drug in patients ranged 45-49kg, IV ABA in 50-59kg and SC ABA in patients over 60kg. With IV vials optimization IFX was the least expensive drug in patients under 69kg and SC ABA over 70kg. Assuming comparable effectiveness of biological drugs, patient's weight is a variable to consider, potentials savings could reach €20,000 in two years.

    Pertuzumab (Perjeta®) is a humanized anti-HER2 monoclonal antibody that binds to the extracellular dimerization subdomain of the HER2 receptor and reduces HER2 intracellular signalling by preventing HER2 from forming heterodimers with other HER receptors. Inhibition of HER2 signalling results in a reduction of tumour cell proliferation, invasiveness and survival. Pertuzumab and trastuzumab bind to different sites on the HER2 receptor and have complementary antitumour activities; they act synergistically in inhibiting the growth of HER2-overexpressing breast cancer cell lines in vitro. The efficacy of intravenous pertuzumab (840 mg loading dose, then 420 mg every 3 weeks) in combination with trastuzumab plus docetaxel in the first-line treatment of HER2-positive metastatic breast cancer was demonstrated in the randomized, double-blind, placebo-controlled, multinational, phase III CLEOPATRA trial. Pertuzumab in combination with trastuzumab and docetaxel significantly increased independently assessed median progression-free survival (primary endpoint), objective response rate and overall survival compared with placebo in combination with trastuzumab and docetaxel. Pertuzumab had an acceptable tolerability profile when added to trastuzumab and docetaxel in the pivotal CLEOPATRA trial. Thus, pertuzumab is a valuable addition to the growing list of anti-HER2 targeted therapies for breast cancer.

    The aim of this study was the assessment of semi-quantified salivary gland dynamic scintigraphy (SGdS) parameters independently and in an integrated way in order to predict primary Sjögren's syndrome (pSS). Forty-six consecutive patients (41 females; age 61 ± 11 years) with sicca syndrome were studied by SGdS after injection of 200 MBq of pertechnetate. In sixteen patients, pSS was diagnosed, according to American-European Consensus Group criteria (AECGc). Semi-quantitative parameters (uptake (UP) and excretion fraction (EF)) were obtained for each gland. ROC curves were used to determine the best cut-off value. The area under the curve (AUC) was used to estimate the accuracy of each semi-quantitative analysis. To assess the correlation between scintigraphic results and disease severity, semi-quantitative parameters were plotted versus Sjögren's syndrome disease activity index (ESSDAI). A nomogram was built to perform an integrated evaluation of all the scintigraphic semi-quantitative data. Both UP and EF of salivary glands were significantly lower in pSS patients compared to those in non-pSS (p quantitative parameters and ESSDAI. The proposed nomogram accuracy was 87%. SGdS is an accurate and reproducible tool for the diagnosis of pSS. ESSDAI was not shown to be correlated with SGdS data. SGdS should be the first-line imaging technique in patients with suspected pSS.

    In a phase II trial, we evaluated chlorambucil and rituximab (CLB-R) as first-line induction treatment with or without R as maintenance for elderly chronic lymphocytic leukemia (CLL) patients. Treatment consisted of eight 28-day cycles of CLB (8 mg/m(2) /day, days 1-7) and R (day 1 of cycle 3, 375 mg/m(2) ; cycles 4-8, 500 mg/m(2) ). Responders were randomized to 12 8-week doses of R (375 mg/m(2) ) or observation. As per intention-to-treat analysis, 82.4% (95% CI, 74.25-90.46%) of 85 patients achieved an overall response (OR), 16.5% a complete response (CR), 2.4% a CR with incomplete bone marrow recovery. The OR was similar across Binet stages (A 86.4%, B 81.6%, and C 78.6%) and age categories (60-64 years, 92.3%; 65-69, 85.2%; 70-74, 75.0%; ≥75, 81.0%). CLB-R was well tolerated. After a median follow-up of 34.2 months, the median progression-free survival (PFS) was 34.7 months (95% CI, 33.1-39.5). TP53 abnormalities, complex karyotype, and low CD20 gene expression predicted lack of response; SF3B1 mutation and BIRC3 disruption low CR rates. IGHV mutations significantly predicted PFS. R maintenance tended towards a better PFS than observation and was safe and most beneficial for patients in partial response and for unmutated IGHV cases. CLB-R represents a promising option for elderly CLL patients. Copyright © 2014 Wiley Periodicals, Inc.

    Full Text Available Purpose : To investigate the efficacy of topiramate monotherapy in West syndrome prospectively. Methods : The study population included 28 patients (15 male and 13 female children aged 2 to 18 months diagnosed with West syndrome. After a 2-week baseline period for documentation of the frequency of spasms, topiramate was initiated at 2 mg/kg/day. The dose was increased by 2 mg/kg every week to a maximum of 12 mg/ kg/day. Clinical assessment was based on the parents’ report and a neurological examination every 2 weeks for the first 2 months of treatment. The baseline electroencephalograms (EEGs were compared with the post-treatment EEGs at 2 weeks and 1 month. Results : West syndrome was considered to be cryptogenic in 7 of the 28 patients and symptomatic in 21 patients. After treatment, 11 patients (39% became spasm-free, 6 (21% had more than 50% spasmsreduction, 3 (11% showed less than 50% reduction, and 8 (29% did not respond. The effective daily dose for achieving more than 50% reduction in spasm frequency, including becoming spasm-free, was found to be 5.8±1.1 mg/kg/day. Nine patients (32% showed complete disappearance of spasms and hypsarrhythmia, and 11 (39% showed improved EEG results. Despite adverse events (4 instances of irritability, 3 of drowsiness, and 1 of decreased feeding, no patients discontinued the medication. Conclusion : Topiramate monotherapy seems to be effective and well tolerated as a first line therapy for West syndrome and is not associated with serio
