Intracerebral efficacy and tolerance of nivolumab in non–small-cell lung cancer patients with brain metastases

International audienceObjectives: Although nivolumab has shown efficacy against non-small-cell lung cancers (NSCLCs), patients with active brain metastases (BMs) were excluded from pivotal clinical trials. Hence, data regarding nivolumab intracerebral activity and safety in NSCLC patients with BMs are scarce.Materials and methods: We conducted a retrospective multicenter study on NSCLC patients with BMs treated with nivolumab. The primary endpoint was intracerebral objective response rate (IORR), according to RECIST criteria. Secondary endpoints included intracerebral control rate, intracerebral and general progression-free survival (PFS), overall survival (OS) and tolerance.Results and conclusion: Forty-three patients were included. BMs were locally pretreated in 34 (79%) patients and active in 16 (37%) patients. Median follow-up was 5.7 (95% CI: 2.7-8.4) months. IORR and extracerebral response rate were, respectively, 9% (95% CI: 3-23%) and 11% (95% CI: 4-26%). Intracerebral control rate was 51% (95% CI: 37-66%). Median intracerebral and general PFS lasted 3.9 (95% CI: 2.8-11.1) and 2.8 (95% CI: 1.8-4.6) months, respectively. Median OS was 7.5 (95% CI: 5.6-not reached) months. Five neurological adverse events occurred, including 1 grade-4 transient ischemic attack of uncertain imputability and 1 grade-3 neurological deficit; neither required nivolumab discontinuation. Nivolumab intracerebral activity was similar to its reported extracerebral efficacy, with an acceptable safety profile. Prospective and controlled data are needed to determine nivolumab's place in treatment of NSCLC patients with BMs

Non-Small Cell Lung Cancer Patients Harboring HER2 Mutations: Clinical Characteristics and Management in a Real-Life Setting. Cohort HER2 EXPLORE GFPC 02–14

Background: Mutation of human receptor tyrosine kinase epidermal growth factor receptor-2 (HER2) is a rare event, found in approximately 1% non-small cell lung cancers (NSCLC). The objective was to investigate the clinical characteristics and management of HER2-mutated NSCLCs in a real-life setting. Methods: This multicenter study described NSCLCs harboring HER2 mutations diagnosed between January 2012 and December 2014, according their clinical characteristics, management, and outcomes: response rate (RR), progression-free survival (PFS), and overall survival (OS). Results: Thirty patients were included: 66.7% women; median age 65.2 ± 12 years; never or former smokers 73.3%. Of the stage IV patients (n = 23), 86% received first-line platin doublet chemotherapy: RR 61.5% and PFS 6.7 (95% CI 5.9-9.5) months; 52.1% received a second-line therapy: RR 18.2% and PFS 4.9 (95% CI 2.5-11.9) months. Median OS of stage IV was 10.7 months and 2-year OS was 27.2% (95% CI 11.7-63.2). All patients with stage I-III NSCLCs were alive at 2 years. Conclusion: The rarity of HER2-mutated NSCLCs requires specific studies.

Octogenarians with EGFR-mutated non-small cell lung cancer treated by tyrosine-kinase inhibitor a multicentric real-world study assessing tolerance and efficacy (OCTOMUT study)

International audienceObjective. To assess efficacy and tolerance of EGFR tyrosine-kinase inhibitors (TKIs) for advanced EGFR-mutated non-small cell lung cancer (NSCLC) in octogenarians.Patients and methods. Patients aged 80 years or older with EGFR-mutated NSCLC treated by EGFR TKI between January 2011 and March 2015 whatever the line of treatment were retrospectively selected.Results. 20 centers retrospectively included 114 patients (women, 77.2%; Caucasians, 98.3%; mean age, 83.9 years). A performance status of 0–1 or 2–3 at diagnosis was reported for 71.6% and 28.4% of patients, respectively. Overall, 95.6% of patients had adenocarcinomas and histological stage at diagnosis was stage IV for 79.8% of patients. EGFR mutations were identified mainly on exon 19 (46.5%) and exon 21 (40.4%). A geriatric assessment was performed in 35.1% of patients. TKI treatment was administered to 97.3% of patients as first or second line of treatment. Overall response rate and disease control rate were 63.3% (69/109) and 78.9% (86/109), respectively. Median progression-free survival was 11.9 months (95% confidence interval [CI], 8.6–14.7) and median overall survival was 20.9 months (95% CI, 14.3–27.1). After progression, 36/95 (37.9%) patients received a new line of chemotherapy. Main toxicities were cutaneous for 66.7% of patients (grade 3–4, 10%), diarrhea for 56.0% (grade 3–4, 15%; grade 5, 2%) and others for 25.7% (grade 3–4, 41%).Conclusions. Octogenarians with EGFR-mutated NSCLC treated by EGFR TKI had clinical outcomes and toxicity profile comparable to younger patients. Geriatric assessment appeared to be underused in this population

Elective extra corporeal membrane oxygenation for high-risk rigid bronchoscopy

International audienceThe use of extracorporeal membrane oxygenation for high-risk rigid bronchoscopy has been reported in few urgent cases. We report our experience with this approach which was planned electively in five cases on 202 procedures (2.5%). It was proposed because of the potential inability to ventilate the lungs using conventional techniques due to extensive tracheobronchial lesions or the risk of major intraoperative bleeding related to disease characteristics. There were no intraoperative complications and postoperative course was favourable in all patients. With a maximum follow-up of 3 years and 7 months, all patients are alive with no tracheostomy despite major morbidities
