Randomized Phase III Trial of Sequential Chemoradiotherapy Compared With Concurrent Chemoradiotherapy in Locally Advanced Non–Small-Cell Lung Cancer: Groupe Lyon-Saint-Etienne d'Oncologie Thoracique–Groupe Français de Pneumo-Cancérologie NPC 95-01 Study

PURPOSE We conducted a phase III study to compare the survival impact of concurrent versus sequential treatment with radiotherapy (RT) and chemotherapy (CT) in unresectable stage III non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Patients were randomly assigned to one of the two treatment arms. In the sequential arm, patients received induction CT with cisplatin (120 mg/m2) on days 1, 29, and 57, and vinorelbine (30 mg/m2/wk) from day 1 to day 78, followed by thoracic RT at a dose of 66 Gy in 33 fractions (2 Gy per fraction and 5 fractions per week). In the concurrent arm, the same RT was started on day 1 with two concurrent cycles of cisplatin 20 mg/m2/d and etoposide 50 mg/m2/d (days 1 to 5 and days 29 to 33); patients then received consolidation therapy with cisplatin 80 mg/m2 on days 78 and 106 and vinorelbine 30 mg/m2/wk from days 78 to 127. RESULTS Two hundred five patients were randomly assigned. Pretreatment characteristics were well balanced between the two arms. There were six toxic deaths in the sequential arm and 10 in the concurrent arm. Median survival was 14.5 months in the sequential arm and 16.3 months in the concurrent arm (log-rank test P = .24). Two-, 3-, and 4-year survival rates were better in the concurrent arm (39%, 25%, and 21%, respectively) than in the sequential arm (26%, 19%, and 14%, respectively). Esophageal toxicity was significantly more frequent in the concurrent arm than in the sequential arm (32% v 3%). CONCLUSION Although not statistically significant, clinically important differences in the median, 2-, 3-, and 4-year survival rates were observed, with a trend in favor of concurrent chemoradiation therapy, suggesting that is the optimal strategy for patients with locally advanced NSCLC.

Randomized, Phase III Study of Gemcitabine or Erlotinib Maintenance Therapy Versus Observation, With Predefined Second-Line Treatment, After Cisplatin-Gemcitabine Induction Chemotherapy in Advanced Non–Small-Cell Lung Cancer

PURPOSE This phase III study investigated whether continuation maintenance with gemcitabine or switch maintenance with erlotinib improves clinical outcome compared with observation in patients with advanced non-small-cell lung cancer (NSCLC) whose disease was controlled after cisplatin-gemcitabine induction chemotherapy. PATIENTS AND METHODS Four hundred sixty-four patients with stage IIIB/IV NSCLC without tumor progression after four cycles of cisplatin-gemcitabine were randomly assigned to observation or to gemcitabine (1,250 mg/m(2) days 1 and 8 of a 3-week cycle) or daily erlotinib (150 mg/day) study arms. On disease progression, patients in all three arms received pemetrexed (500 mg/m(2) once every 21 days) as predefined second-line therapy. The primary end point was progression-free survival (PFS). RESULTS PFS was significantly prolonged by gemcitabine (median, 3.8 v 1.9 months; hazard ratio [HR], 0.56; 95% CI, 0.44 to 0.72; log-rank P < .001) and erlotinib (median, 2.9 v 1.9 months; HR, 0.69; 95% CI, 0.54 to 0.88; log-rank P = .003) versus observation; this benefit was consistent across all clinical subgroups. Both maintenance strategies resulted in a nonsignificant improvement in overall survival (OS); patients who received second-line pemetrexed or with a performance status of 0 appeared to derive greater benefit. Exploratory analysis showed that magnitude of response to induction chemotherapy may affect the OS benefit as a result of gemcitabine maintenance. Maintenance gemcitabine and erlotinib were well tolerated with no unexpected adverse events. CONCLUSION Gemcitabine continuation maintenance or erlotinib switch maintenance significantly reduces disease progression in patients with advanced NSCLC treated with cisplatin-gemcitabine as first-line chemotherapy. Response to induction chemotherapy may affect OS only for continuation maintenance.

Association of EGFR L858R Mutation in Circulating Free DNA With Survival in the EURTAC Trial

IMPORTANCE The EURTAC trial demonstrated the greater efficacy of erlotinib compared with chemotherapy for the first-line treatment of European patients with advanced non-small-cell lung cancer (NSCLC) harboring oncogenic epidermal growth factor receptor (EGFR) mutations (exon 19 deletion or L858R mutation in exon 21) in tumor tissue. OBJECTIVE To assess the feasibility of using circulating free DNA (cfDNA) from blood samples as a surrogate for tumor biopsy for determining EGFR mutation status and to correlate EGFR mutations in cfDNA with outcome. DESIGN, SETTING, AND PARTICIPANTS This prespecified analysis was a secondary objective of the EURTAC trial using patients included in the EURTAC trial from 2007 to 2011 with available baseline serum or plasma samples. Patients had advanced NSCLC, oncogenic EGFR mutations in the tumor, and no prior chemotherapy for metastatic disease and were treated with erlotinib or chemotherapy. EGFR mutations were examined in cfDNA isolated from 97 baseline blood samples by our novel peptide nucleic acid-mediated 5´ nuclease real-time polymerase chain reaction (TaqMan) assay. MAIN OUTCOMES AND MEASURES Overall survival (OS), progression-free survival (PFS), and response to therapy were correlated with type of EGFR mutations in cfDNA. RESULTS In samples from 76 of 97 (78%) patients with usable blood samples, EGFR mutations in cfDNA were detected. Median OS was shorter in patients with the L858R mutation in cfDNA than in those with the exon 19 deletion (13.7 [95% CI, 7.1-17.7] vs 30.0 [95% CI, 19.3-37.7] months; P < .001). Univariate analyses of patients with EGFR mutations in cfDNA identified the L858R mutation in tumor tissue or in cfDNA as a marker of shorter OS (hazard ratio [HR], 2.70 [95% CI, 1.60-4.56]; P < .001) and PFS (HR, 2.04 [95% CI, 1.20-3.48]; P = .008). For patients with the L858R mutation in tissue, median OS was 13.7 (95% CI, 7.1-17.7) months for patients with the L858R mutation in cfDNA and 27.7 (95% CI, 16.1-46.2) months for those in whom the mutation was not detected in cfDNA (HR, 2.22 [95% CI, 1.09-4.52]; P = .03). In the multivariate analysis of the 76 patients with EGFR mutations in cfDNA, only erlotinib treatment remained an independent predictor of longer PFS (HR, 0.41 [95% CI, 0.23-0.74]; P = .003). CONCLUSIONS AND RELEVANCE The peptide nucleic acid-mediated 5´ nuclease real-time polymerase chain reaction (TaqMan) assay used in this study can be used to efficiently assess EGFR mutations in cfDNA. The L858R mutation in cfDNA may be a novel surrogate prognostic marker. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00446225.

Use of a Comprehensive Geriatric Assessment for the Management of Elderly Patients With Advanced Non–Small-Cell Lung Cancer: The Phase III Randomized ESOGIA-GFPC-GECP 08-02 Study

PURPOSE Comprehensive geriatric assessment (CGA) is recommended to assess the vulnerability of elderly patients, but its integration in cancer treatment decision making has never been prospectively evaluated. Here, in elderly patients with advanced non-small-cell lung cancer (NSCLC), we compared a standard strategy of chemotherapy allocation on the basis of performance status (PS) and age with an experimental strategy on the basis of CGA. PATIENTS AND METHODS In a multicenter, open-label, phase III trial, elderly patients ≥ 70 years old with a PS of 0 to 2 and stage IV NSCLC were randomly assigned between chemotherapy allocation on the basis of PS and age (standard arm: carboplatin-based doublet if PS ≤ 1 and age ≤ 75 years; docetaxel if PS = 2 or age > 75 years) and treatment allocation on the basis of CGA (CGA arm: carboplatin-based doublet for fit patients, docetaxel for vulnerable patients, and best supportive care for frail patients). The primary end point was treatment failure free survival (TFFS). Secondary end points were overall survival (OS), progression-free survival, tolerability, and quality of life. RESULTS Four hundred ninety-four patients were randomly assigned (standard arm, n = 251; CGA arm, n = 243). Median age was 77 years. In the standard and CGA arms, 35.1% and 45.7% of patients received a carboplatin-based doublet, 64.9% and 31.3% received docetaxel, and 0% and 23.0% received best supportive care, respectively. In the standard and CGA arms, median TFFS times were 3.2 and 3.1 months, respectively (hazard ratio, 0.91; 95% CI, 0.76 to 1.1), and median OS times were 6.4 and 6.1 months, respectively (hazard ratio, 0.92; 95% CI, 0.79 to 1.1). Patients in the CGA arm, compared with standard arm patients, experienced significantly less all grade toxicity (85.6% v 93.4%, respectively P = .015) and fewer treatment failures as a result of toxicity (4.8% v 11.8%, respectively; P = .007). CONCLUSION In elderly patients with advanced NSCLC, treatment allocation on the basis of CGA failed to improve the TFFS or OS but slightly reduced treatment toxicity.

Multicentre phase II study of cisplatin–etoposide chemotherapy for advanced large-cell neuroendocrine lung carcinoma: the GFPC 0302 study

BACKGROUND The optimal treatment of large-cell neuroendocrine carcinoma (LCNEC) of the lung remains unclear. Here, our primary objective was to assess the efficacy of cisplatin-etoposide doublet chemotherapy in advanced LCNEC. Accuracy of the pathological diagnosis and treatment toxicity were assessed as secondary objectives. PATIENTS AND METHODS Prospective, multicentre, single-arm, phase II study with a centralised review of treatment-response and pathological data. Patients had untreated performance status (PS) 0/1 stage IV/IIIB LCNEC and received cisplatin (80 mg/m22 d1) and etoposide (100 mg/m22 d1-3) every 21 days. RESULTS Eighteen centres included 42 patients (mean age, 59 ± 9 years; 69% men; median of four cycles/patient). At least one grade-3/4 toxicity occurred in 59% of patients (neutropaenia, thrombocytopaenia, and anaemia in 32%, 17%, and 12%, respectively). The median progression-free survival (PFS) and overall survival (OS) were 5.2 months (95% confidence interval, CI, 3.1-6.6) and 7.7 months (95% CI, 6.0-9.6), respectively. The centralised pathologist review reclassified 11 of 40 (27.5%) patients: 9 as small-cell lung cancer, 1 as undifferentiated non-small-cell lung cancer, and 1 as atypical carcinoid. Survival data were not significantly changed by excluding the reclassified patients. CONCLUSIONS The pathological diagnosis of LCNEC is difficult. The outcomes of advanced LCNEC treated with cisplatin-etoposide doublets are poor, similar to those of patients with advanced small-cell lung carcinoma (SCLC).

Feasibility and clinical impact of re-biopsy in advanced non small-cell lung cancer: A prospective multicenter study in a real-world setting (GFPC study 12-01)

OBJECTIVES When advanced non-small-cell lung cancer (NSCLC) progresses during first-line treatment, re-biopsy may be indicated to detect a possible new biological profile (comparison to initial status, emergence of resistance biomarkers, or assessment of new biomarkers). The aim of this pragmatic prospective multicenter study was to assess the feasibility and clinical utility of re-biopsy in advanced NSCLC in a real-world setting. METHODS The main inclusion criteria were advanced NSCLC with an indication for repeat biopsy identified by the patients clinician. The primary outcome was the percentage of successful procedures. Secondary outcomes were the type of procedure, new biological status, tolerability of the procedure, and clinical utility (treatment modification). RESULTS From May 2012 to May 2013, 18 centers enrolled 100 patients (males: 44%; median age: 64.8 years; PS 0/1: 88%; adenocarcinoma: 89%; EGFR mutated: 50%; no initial biological profile: 16.4%). Re-biopsy was not possible in 19.5% of cases and provided no or too few tumor cells in 25.6% of cases. Repeat biopsy was useful for guiding treatment in 30.4% (25/82) of cases. Complications were infrequent (2 cases of moderate bleeding and 1 case of pneumothorax). CONCLUSION Re-biopsy of advanced NSCLC is feasible in the real-world setting, with acceptable adverse events. Guidelines are needed on the indications of re-biopsy, the choice of procedure, the sampling site, and laboratory analysis.

Economics of treatments for non-small cell lung cancer.

AbstractThe purpose of this article is to review the economics of treatments for non-small cell lung cancer (NSCLC). We systematically analysed the cost effectiveness of treatments for the different stages of NSCLC, with particular emphasis on more recently approved agents.Numerous economic analyses in NSCLC have been conducted, with a variety of methods and in a number of countries. In patients with localized disease, adjuvant chemotherapy appears to have greater cost effectiveness than observation; however, there are few published data. In locally advanced disease, combined modalities (chemotherapy, surgery and/or radiotherapy) are probably cost effective, but high-quality economic analyses are lacking. In advanced NSCLC, third-generation chemotherapies used in the first-line setting can be administered with acceptable incremental cost effectiveness. In the second-line setting, new agents (docetaxel, pemetrexed and erlotinib) have acceptable cost effectiveness. The lack of cost-utility analyses for elderly patients and patients with a poor prognosis rules out firm conclusions.This review suggests that most therapies for NSCLC are cost effective when the patient has a good performance status, with an incremental costeffectiveness ratio under

Economic Evaluation of Epilepsy in Kiremba (Burundi): A Case–Control Study

US50 000 per life-year gained in the majority of cases.

Cost-effectiveness of second-line chemotherapy for non-small cell lung cancer: an economic, randomized, prospective, multicenter phase III trial comparing docetaxel and pemetrexed: the GFPC 05-06 study.

Summary:  Purpose: Epilepsy is a common disease whose prevalence across Africa is extremely variable (from 5 to 74‰). Its social and economic consequences in this continent are not well established. The objective of this study was to compare the cost of care of patients with epilepsy with that of controls in the commune of Kiremba in Burundi.

Cost of lung cancer: a methodological review.

Background: There are few data on the cost-effectiveness of second-line chemotherapies for non-small cell lung cancer (NSCLC). The objective of this phase III, randomized, multicenter, prospective study was to compare the cost-effectiveness of docetaxel and pemetrexed, two widely used drugs. Methods: We compared, from a payers perspective, the directs costs and effectiveness of docetaxel (75 mg/m2, arm A) and pemetrexed (500 mg/m2, arm B) administered every 3 weeks to NSCLC patients who had progressed after first-line platinum-based chemotherapy. Monthly health utilities (based on disease states: responding, stable or progressive, and grade 3/4 toxicities) were derived from the literature. Costs were prospectively assessed. Results: One hundred fifty patients were enrolled between February 2006 and June 2008. The patients in the docetaxel and pemetrexed arms had similar clinical characteristics and treatment efficacy (respective objective response rates 10.7% and 12%; median progression-free survival times 2.8 and 2.5 months; median survival times 8.0 and 6.4 months, respectively). Grade 3/4 toxicities were significantly less frequent with pemetrexed (52.0% versus 33.3%, p = 0.02). Docetaxel was associated with lower treatment-period costs (&U20AC;9709 ± &U20AC;6272 versus &U20AC;13,436 ± &U20AC;6508, p < 0.001). Docetaxel had a more favorable cost-utility ratio than pemetrexed. When compared with best supportive care, the cost-utility was &U20AC;32,652/quality-adjusted life year for docetaxel and &U20AC;40,980/quality-adjusted life year for pemetrexed. Conclusion: Second-line treatment for NSCLC is more cost-effective with docetaxel than with pemetrexed. Both strategies have acceptable cost-effectiveness ratios compared with commonly used and reimbursed regimens for advanced NSCLC.
