In the Intergroupe Francophone de Cancérologie Thoracique 0501 trial the carboplatinpaclitaxel chemotherapy increased toxicity (most frequent, decreased neutrophil count, asthenia). We longitudinally compared health-related quality of life (HRQoL) of the two treatment arms. In total, 451 patients aged 70-89 years with advanced non-small cell lung cancer (NSCLC) were randomly assigned to receive carboplatin plus paclitaxel or vinorelbine or gemcitabine. HRQoL was assessed by means of the European Organisation for Research and Treatment of Cancer QLQ-C30 questionnaire at baseline, week 6 and week 18. Using a five-point decrease as the minimal clinically important difference, patients treated with the chemotherapy doublet exhibited a significant longer time until definitive deterioration (TUDD) for two HRQoL dimensions: physical functioning (median TUDD: 2.04 for the doublet versus 1.71 months for monotherapy; log-rank p=0.01) and nausea and vomiting (median: not reached versus 4.83, respectively; log-rank p=0.046). Cox multivariate analysis revealed the carboplatin and paclitaxel arm to be independently associated with longer TUDD for these two HRQoL dimensions. In addition, TUDD didn't significantly differ between the two arms for all the other HRQoL dimensions. The chemotherapy doublet did not reduce TUDD in elderly patients with advanced NSCLC. Moreover, TUDD was prolonged for two HRQoL dimensions, namely physical functioning and nausea and vomiting.

Background: Epidermal growth factor and v-Ki-ras2 Kirsten ras sarcoma (KRAS) mutation status, although associated with EGFR- tyrosine kinase inhibitor (TKI) efficacy, has not been used in clinical practice until recently. The prospective Evaluation of the EGFR Mutation status for the administration of EGFR-TKIs in non small cell lung Carcinoma (ERMETIC) study aimed to implement these biomarkers in France. Methods: Between March 2007 and April 2008, EGFR and KRAS were studied by sequencing DNA tumor specimens from 522 consecutive advanced non-small-cell lung cancer patients treated with EGFR-TKI, mostly in second- or third-line settings. Cox models were used to investigate the impact of patient characteristics and mutations on progression-free survival (PFS) and overall survival (OS). Added value from mutation status was evaluated using likelihood ratio (LR) tests. Classification and regression tree analysis aimed to identify homogeneous groups in terms of survival. Results: Among the 522 patients, 87% were white, 32% were women, and 18% were never-smokers, with 65% presenting with adenocarcinoma. Biological data were available for 307 patients, showing 44 EGFR mutations (14%) and 42 KRAS (14%) mutations. Median PFS was 2.4 months (interquartile range, 1.4-4.6) and median OS 5.6 months (interquartile range, 2.2-14.0). Factors independently associated with PFS were performance status 1 or 2 to 3 (hazards ratio [HR] = 1.5, 95% confidence interval [CI] 1.1-1.9; and HR = 2.3, CI 1.7-3.1, respectively; p < 0.001); former or current smoker status (HR = 1.8, CI 1.4-2.4 and 2.0,CI 1.4-2.8, respectively; p < 0.001); nonadenocarcinoma histology (squamous cell: HR = 0.9 CI 0.7-1.2]; others: HR = 1.6, 1.3-2.1; p < 0.001); at least two metastatic sites (HR = 1.3, CI 1.1-1.6 and 1.6, CI 1.3-2.1, respectively; p < 0.001); prior taxane-based chemotherapy (HR = 1.3, CI 1.0-1.3, p = 0.01); non-white (HR = 0.7, CI 0.5-0.9, p = 0.009). Similar results were found for OS. In addition, EGFR and KRAS mutations were significantly associated with PFS (HR = 0.5, CI 0.3-0.7 and HR = 1.2, CI 0.8-1.8, respectively, versus no mutation; LR p = 0.001). In the OS model, adjusted HR was 0.7 (0.4-1.0) for EGFR mutation and 1.7 (1.1-2.4) for KRAS (LR p = 0.004). Classification and regression tree analysis revealed EGFR mutation to be the primary factor for identifying homogeneous patient subgroups in terms of PFS. Conclusions: EGFR and KRAS status independently impacts outcomes in advanced non-small-cell lung cancer patients treated with EGFR-TKI. However, EGFR status impacts both PFS and OS whereas KRAS only impacts OS. These findings support the nationwide use of EGFR status for patient selection before EGFR-TKI therapy. The role of KRAS mutations remains to be elucidated. Copyright © 2012 by the International Association for the Study of Lung Cancer.

HYPOTHESIS:: This study explored whether chemotherapy after first-line gefitinib was effective in patients with advanced lepidic predominant adenocarcinoma (LPA), formerly advanced bronchioloalveolar carcinoma, who were enrolled in the Intergroupe Francophone de Cancérologie Thoracique (IFCT)-0401 trial. METHODS:: Overall, 88 patients presenting advanced LPA were enrolled in the IFCT-0401 trial, receiving gefitinib as first-line therapy. No predefined second-line treatment was mandatory in the case of progression or limiting toxicity under gefitinib. However, the carboplatin plus paclitaxel regimen was recommended for patients with a performance status (PS) 0 or 1 and gemcitabine monotherapy for those with a PS 2. For these patients, data concerning treatment efficacy was collected from the IFCT-0401 trial database. RESULTS:: In total, 47 patients (53%) received second-line treatment after the failure of gefitinib, with 43 having PS 0 or 1. Regarding treatment, 43 were treated with chemotherapy, with 38 receiving a platinum-doublet regimen (taxane-based, n = 29; gemcitabine-based, n = 9) and five receiving monotherapy (gemcitabine, n = 3; pemetrexed, n = 2). The overall response rate (ORR) to chemotherapy was 21% (95% confidence interval [CI]: 10-36), disease control rate 56% (95% CI: 40-71), and median progression-free survival (PFS) 3.0 months (95% CI: 2.4-4.9). For patients receiving a platinum doublet (n = 38), ORR was 21% (95% CI: 10-37), with disease control rate being 55% (95% CI: 38-71), and median PFS 2.9 months (95% CI: 2.4-4.4). For patients receiving taxane-based regimen (n = 29) and gemcitabine-based regimen (n = 12), ORR was 28% and 0%, respectively, with a median PFS of 3.3 and 2.0 months, respectively, (p = 0.0243). The two patients receiving pemetrexed experienced a prolonged response. Multivariate Cox model analysis revealed that only the use of taxane-based chemotherapy or pemetrexed was related to PFS. CONCLUSION:: Platinum-doublet chemotherapy showed some effectiveness in treating advanced LPA patients after first-line gefitinib. Our findings also suggest that taxane-based chemotherapy and pemetrexed should be investigated further in future clinical trials.

Purpose: To evaluate prognostic and predictive molecular biomarkers in early-stage non-small cell lung carcinoma (NSCLC) receiving neoadjuvant chemotherapy. Experimental Design: The IFCT-0002 trial compared two neoadjuvant regimens in 528 stages I to II NSCLC patients. DNA extraction of snap-frozen surgical samples taken from 208 patients receiving gemcitabine-cisplatin or paclitaxel-carboplatin regimens allowed for the identification of 3p allelic imbalance, Ras association domain family 1A (RASSF1A) and death-associated protein kinase 1 (DAPK1) promoter methylation, and epidermal growth factor receptor, K-ras, and TP53 mutations. Multivariate analysis identified prognostic and predictive effects of molecular alterations. A Bootstrapping approach was used to assess stability of the prognostic models generating optimism corrected indexes. Results: RASSF1A methylation correlated significantly with shorter disease-free survival (DFS; adjusted HR = 1.88, 95% CI: 1.25-2.82, P = 0.0048) and shorter median overall survival (OS; adjusted HR = 2.01, 95% CI: 1.26-3.20, P = 0.020). A computed bootstrap resampling strategy led to a prognostic model, including RASSF1A, DAPK1, and tumor stage, dividing patients into three prognostic groups, with median OSranging from 34 months for high-risk patients (HR for death=3.85,95%CI: 1.79-6.40) to more than 84 months for moderate (HR=1.85,95%CI: 0.97-3.52) and low-risk patients (reference group; P=0.00044). In addition, RASSF1A methylation predicted longer DFS in patients treated with paclitaxel-carboplatin compared with gemcitabine-cisplatin (adjusted HR = 0.47, 95% CI: 0.23-0.97, P interaction = 0.042). Conclusions: Following neoadjuvant chemotherapy, RASSF1A methylation negatively impacted prognosis of early-stage NSCLC. Along with DAPK1 methylation and tumor stage, RASSF1A methylation allowed definition of three subgroups with strikingly different prognosis. Conversely, significantly longer DFS following paclitaxel-based neoadjuvant chemotherapy for patients whose tumors showed RASSF1A methylation suggested its predictive interest in stages I and II NSCLC. ©2012 AACR.

DNA repair is a double-edged sword in lung carcinogenesis. When defective, it promotes genetic instability and accumulated genetic alterations. Conversely these defects could sensitize cancer cells to therapeutic agents inducing DNA breaks.We used immunohistochemistry (IHC) to assess MSH2, XRCC5, and BRCA1 expression in 443 post-chemotherapy specimens from patients randomized in a Phase 3 trial, comparing two neoadjuvant regimens in 528 Stage I-II non-small cell lung cancer (NSCLC) patients (IFCT-0002). O6MGMT promoter gene methylation was analyzed in a subset of 208 patients of the same trial with available snap-frozen specimens.Median follow-up was from 90 months onwards. Only high BRCA1 (n = 221, hazard ratio [HR] = 1.58, 95% confidence interval [CI] [1.07-2.34], p = 0.02) and low MSH2 expression (n = 356, HR = 1.52, 95% CI [1.11-2.08], p = 0.008) significantly predicted better overall survival (OS) in univariate and multivariate analysis. A bootstrap re-sampling strategy distinguished three patient groups at high (n = 55, low BRCA1 and high MSH2, median OS >96 months, HR = 2.5, 95% CI [1.45-4.33], p = 0.001), intermediate (n = 82, median OS = 73.4 p = 0.0596), and low (high BRCA1 and low MSH2, n = 67, median OS = ND, HR = 0.51, 95% CI [0.31-0.83], p = 0.006) risk of death.DNA repair protein expression assessment identified three different groups of risk of death in early-stage lung cancer patients, according to their tumor MSH2 and BRCA1 expression levels. These results deserve prospective evaluation of MSH2/BRCA1 theranostic value in lung cancer patients treated with combinations of DNA-damaging chemotherapy and drugs targeting DNA repair, such as Poly(ADP-ribose) polymerase (PARP) inhibitors.

There is no optimal established therapy for treating advanced or recurrent adenocarcinoma with bronchioloalveolar carcinoma features (ADC-BAC), and it remains unclear whether chemotherapy achieves therapeutic results comparable to those seen in the more common non-small lung carcinoma subtypes. In order to improve the decisions made during the treatment of advanced ADC-BAC, we attempted to better characterize the mucinous and non-mucinous ADC-BAC subtypes. Fifty pathological samples were obtained from 62 patients included in a multicenter prospective phase II trial (IFCT0401) conducted to evaluate gefitinib as a first-line therapy for non-resectable ADC-BAC. These samples were centrally reviewed and re-classified as non-mucinous (n=25) or mucinous (n=25) subtypes. We demonstrated that demographic data, clinical characteristics and stage at presentation (extrathoracic versus lung metastasis, as well as TNM staging) did not distinguish between the two subtypes. In contrast, three biological markers (PAS staining, TTF-1 expression and EGFR genomic gain combined with mutation analysis) enabled us to independently segregate all but 2 of the 50 patients into the mucinous and non-mucinous ADC-BAC subtypes. Finally, only mucinous tumors appeared to be resistant to epidermal growth factor receptor. -tyrosine kinase inhibitors (EGFR-TKIs). Additional prospective studies are required to better approach therapeutic strategy in mucinous tumors, which are a distinct entity from non-mucinous tumors. © 2009 Elsevier Ireland Ltd.

Background.- Cisplatin-based chemotherapy and concurrent radiotherapy are the standard treatments for locally advanced unresectable NSCLC. New therapeutic combinations using molecular targeted drugs are needed. Methods.- Eligible patients with previously untreated stage III non squamous, NSCLC will receive thoracic radiation (66 Gy) along with cisplatin (75mg/m2) and pemetrexed (500mg/m2) on day 1 administered intravenously every 21 days for four cycles; weekly cetuximab will be added from the first week of therapy. The primary objective of this phase II study (IFCT 0803) is to assess the disease control rate at the 16th week, one month after the completion of the treatment. Based on a two-stage Simon approach, a total of 106 patients are required with an interim analysis of the first 34 planned. Expected results.- This trial will provide information on the feasibility, efficacy and tolerability of this new therapeutic combination. Should the primary objective be achieved, a phase III randomised study testing the position of cetuximab could be considered. © 2011 SPLF. Published by Elsevier Masson SAS. All rights reserved.

The aim of this article is to summarise the published data on prognostic and predictive biomarkers for early-stage non-small cell lung cancer (NSCLC), and discuss how to integrate them into clinical trials. Large phase III trials have been published in resected NSCLC with biomarkers identifying subsets of patients benefitting from perioperative chemotherapy. Initial findings of predictive implications for the DNA repair protein, ERCC1, were not confirmed in a larger series of patients due to the versatility of the commercially available monoclonal ERCC1 antibody. Prediction of survival by RRM1 tumour expression was not confirmed in a prospective phase III trial in 275 patients with stage IV disease, precluding its use in early-stage NSCLC. BRCA1 mRNA tumour content also failed to predict platinum resistance in 287 stage IV NSCLC patients included in a phase II trial, and the results of a similar trial in early-stage patients are still pending. Of the several cDNA gene expression studies in early-stage NSCLC with non-overlapping prognostic signatures, few have been replicated in independent cohorts for prognostic value, and none received external validation for predictive value. Therefore, use of biomarkers predicting chemotherapy efficacy still needs additional validation before becoming routine practice in oncogenedriven pan-negative NSCLC patients. © ERS 2013.
