The consequences of the strict health restrictions during the first wave of COVID-19 on lung cancer (LC) patients are not known. This cohort study evaluated the impact of the initial lockdown on ...management of and long-term outcome in LC patients. This exposed-unexposed-type study included two evaluation periods of 6 months each in non-selected patients; one began on the first day of lockdown in 2020, and the other in 2019 during the same calendar period. Various indicators were compared: clinical profiles, management delays and overall survival beyond 2 years. A total of 816 patients from 7 public or private centers were enrolled. The clinical characteristics of the patients in 2020 did not differ from those in 2019, except that the population was older (
= 0.002) with more non-smokers (
= 0.006). Delays for pre-therapeutic medical management were generally reduced after the first imaging in 2020 (1.28 1.1-1.49). In the multivariate analysis, being part of the 2020 cohort was correlated with better prognosis (HR = 0.71 0.5-0.84,
< 0.001). The gain observed in 2020 mainly benefited non-smoking patients, along with ECOG PS 0-2 (
= 0.01), stage 4 (
= 0.003), squamous cell carcinoma (
= 0.03) and receiving systemic therapy (
= 0.03). In conclusion, the first lockdown did not exert any deleterious impact on LC patients.
Objective
Immune checkpoint inhibitors (ICIs) for cancer therapy frequently induce immune‐related adverse effects (IRAEs). Therefore, most patients with preexisting autoimmune diseases have been ...excluded from clinical trials of ICIs. This study was undertaken to evaluate the safety and efficacy of ICIs in patients with preexisting autoimmune disease and cancer.
Methods
A retrospective cohort study was conducted from January 2017 to January 2018 via 3 French national networks of experts in oncology and autoimmunity. Adults with preexisting autoimmune disease who were receiving ICIs were assessed for the occurrence of flare of preexisting autoimmune disease, other IRAEs, and cancer response.
Results
The study included 112 patients who were followed up for a median of 8 months. The most frequent preexisting autoimmune diseases were psoriasis (n = 31), rheumatoid arthritis (n = 20), and inflammatory bowel disease (n = 14). Twenty‐four patients (22%) were receiving immunosuppressive therapy at ICI initiation. Autoimmune disease flare and/or other IRAE(s) occurred in 79 patients (71%), including flare of preexisting autoimmune disease in 53 patients (47%) and/or other IRAE(s) in 47 patients (42%), with a need for immunosuppressive therapy in 48 patients (43%) and permanent discontinuation of ICI in 24 patients (21%). The median progression‐free survival was shorter in patients receiving immunosuppressive therapy at ICI initiation (3.8 months versus 12 months; P = 0.006), confirmed by multivariable analysis. The median progression‐free survival was shorter in patients who experienced a flare of preexisting autoimmune disease or other IRAE, with a trend toward better survival in the subgroup without immunosuppressant use or ICI discontinuation.
Conclusion
Our findings indicate that flares or IRAEs occur frequently but are mostly manageable without ICI discontinuation in patients with a preexisting autoimmune disease. Immunosuppressive therapy at baseline is associated with poorer outcomes.
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.
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.
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).
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.

Background: Alectinib is a standard of care option in advanced ALK-rearranged (ALK+) non-small cell lung cancer (NSCLC) patients (pts), with efficacy established by phase 3 trials, in first-line ...and beyond. There are few efficacy data in unselected populations. Methods: The objective of this study was to evaluate the efficacy of alectinib in real-world setting. All ALK+ advanced NSCLC pts initiating alectinib, between December 13, 2017 (date of access in France) and June 27, 2020, whatever the line, were included in explore ALK study. Patient characteristics, alectinib duration of treatment (DOT), progression-free survival assessed locally (rwPFS), overall survival (OS) according to the prescription line of alectinib, the presence of brain metastases at alectinib initiation, response rate and tolerance were collected from the medical files. Results: The analysis included 223 pts: 46.2% were men, 84.7% had no smoking history or were former smokers, median age was 59 (22-101) years and 95% were adenocarcinomas. Alectinib was initiated as first-line treatment in 119 pts, with a PS of 0/1/>1 in 42%/31%/27% of cases, a median number of metastatic sites of 2 (cerebral, hepatic, bone in 33%, 24% and 32% of cases). In first-line setting, after a median follow-up of 33.7 months (95%CI, 32.2-37.5), the median of rwPFS and DOT were 28.1 (95%CI, 20.7-40.4) and 26.9 (95%CI, 20.2-31.3) months, respectively. The median OS was not reach (NR), the 3-year OS rate was 72.1%. The rwPFS was not significantly different depending on whether or not the patient has brain metastases, 28.1 (95% CI, 14.5-NR) and 30.5 (85% CI, 18.9-40.4) months, respectively. The best response was complete (CR), partial (PR) and stable (SD) in 21%, 58% and 17%. The cerebral response, evaluable in 30/39 of the pts, was CR, PR and SD in 26%, 46% and 23% respectively; 33% of pts had a grade 3 adverse event, resulting in a temporary interruption of treatment in 7.6% of cases and a permanent discontinuation in 5.9% of cases. At the time of progression, 48.1% of pts had a new biopsy (66% of tissue biopsy). Efficacy data for alectinib prescribed as second line and above are summarized in the table. Conclusions: In this large real-world, cohort of unselected advanced ALK+ NSCLC pts, alectinib initiated in 1
st
-line or beyond provides similar efficacy and safety results as obtained in phase III clinical trials. Table: see text
Background
Few real-world data are available in patients with advanced metastatic non-small cell lung cancer (NSCLC) treated with first-line immunotherapy, particularly in those with brain metastases ...at treatment initiation.
Methods
This was a national, retrospective, multicenter study that consecutively included all patients with PD-L1-positive (tumor proportion score ≥ 50%) advanced NSCLC who initiated first-line treatment with pembrolizumab as a single agent between May 2017 (date of availability of pembrolizumab in this indication in France) to November 22, 2019 (approval of the pembrolizumab-chemotherapy combination). Data were collected from medical records with local response assessment.
Results
The cohort included 845 patients and 176 (20.8%) had brain metastases at diagnosis. There were no significant differences in outcomes for patients with and without brain metastases: 9.2 (95% CI 5.6–15) and 8 (95% CI 6.7–9.2,
p
= 0.3) months for median progression-free survival (PFS) and, 29.5 (95% CI 17.2–NA) and 22 (95% CI 17.8–27.1,
p
= 0.3) months for median overall survival (OS), respectively. Overall response rates were 47% and 45% in patients with and without cerebral metastases. In multivariate analysis, performance status 2–4 vs. 0–1 and neutrophil-to-lymphocyte ratio ≥ 4 vs. < 4 were the main independent negative factors for OS; brain metastasis was not an independent factor for OS.
Conclusion
In this large multicenter cohort, nearly 20% of patients initiating pembrolizumab therapy for advanced NSCLC had cerebral metastases. There was no significant difference in response rates, PFS and OS between patients with and without brain metastases.
Purpose
Survivors after acute respiratory distress syndrome (ARDS) due to coronavirus disease 2019 (COVID-19) are at high risk of developing respiratory sequelae and functional impairment. The ...healthcare crisis caused by the pandemic hit socially disadvantaged populations. We aimed to evaluate the influence of socio-economic status on respiratory sequelae after COVID-19 ARDS.
Methods
We carried out a prospective multicenter study in 30 French intensive care units (ICUs), where ARDS survivors were pre-enrolled if they fulfilled the Berlin ARDS criteria. For patients receiving high flow oxygen therapy, a flow ≥ 50 l/min and an FiO
2
≥ 50% were required for enrollment. Socio-economic deprivation was defined by an EPICES (Evaluation de la Précarité et des Inégalités de santé dans les Centres d’Examens de Santé - Evaluation of Deprivation and Inequalities in Health Examination Centres) score ≥ 30.17 and patients were included if they performed the 6-month evaluation. The primary outcome was respiratory sequelae 6 months after ICU discharge, defined by at least one of the following criteria: forced vital capacity < 80% of theoretical value, diffusing capacity of the lung for carbon monoxide < 80% of theoretical value, oxygen desaturation during a 6-min walk test and fibrotic-like findings on chest computed tomography.
Results
Among 401 analyzable patients, 160 (40%) were socio-economically deprived and 241 (60%) non-deprived; 319 (80%) patients had respiratory sequelae 6 months after ICU discharge (81% vs 78%, deprived vs non-deprived, respectively). No significant effect of socio-economic status was identified on lung sequelae (odds ratio (OR), 1.19 95% confidence interval (CI), 0.72–1.97), even after adjustment for age, sex, most invasive respiratory support, obesity, most severe P/F ratio (adjusted OR, 1.02 95% CI 0.57–1.83).
Conclusions
In COVID-19 ARDS survivors, socio-economic status had no significant influence on respiratory sequelae 6 months after ICU discharge.

Background: To determine real-world outcomes with first line pembrolizumab monotherapy, for aNSCLC with PD-L1 TPS ≥50%. Methods: Bispective, national and multicentric study ...including consecutively aNSCLC patients who initiated first-line pembrolizumab monotherapy from May 5, 2017 (marketing authorization of pembrolizumab monotherapy in France) to Nov 22, 2019 (marketing authorization of pembrolizumab-chemotherapy for non-squamous aNSCLC). Data were collected on medical charts. Responses were locally assessed according to RECIST v1.1; overall survival (OS) and real-world progression-free survival (rwPFS) were assessed by Kaplan-Meier method. Results: 845 patients (pts) were included by 33 centres: 67.8% were men, PS 0/1/≥2: 25.5%/46.9%/27.6%, active/former/nonsmokers: 39.1%/51.7%/6.4%, adenocarcinoma: 70.8%; stage IV at diagnosis: 91.6%; median number of metastatic sites at baseline: 2±1 (brain (20.8%), liver (13.9%) and bone (35%)); KRAS mutated: 27.7%, PDL1 TPS > 75%: 53.7% At the cut off date (31 December 2020), on the 783/845 (92.7%) evaluable pts, CR, PR, disease stabilization and progression were reported on 4.7%, 42.6%, 24.1% and 28.6% of cases, respectively; 588 (69.6%) pts had discontinued pembrolizumab, 390 (66.4%) had a first disease progression; 320/390 (82.1%) received a second line treatment, mainly platinum-based chemotherapy (90.6%). With a median follow up of 25,8 95%CI: 24,8-26,7 months, median rwPFS and median OS were 8,2 95%CI: 6,9-9,5 and 22,6 95%CI: 18,5-27,4 months, respectively; 6, 12, 18-months survival rates were 76,8%, 64,8% and 54,3%. 835 adverse events were reported in 48% of the patients, grade ≥3 in 13.8% of cases, mainly asthenia, colitis, pneumonitis. For evaluable patients receiving a platinum-based doublet in second line (266/290, 89%), CR, PR, disease stabilization and progression were reported on 1.9%, 41%, 35.3% and 21.8% of cases, respectively. Uni and multivariate analysis of factors related to OS will be presented at the congress. Conclusions: Despite a less stringent selection of patients, pembrolizumab as a single agent achieves similar tumor shrinkage, rwPFS and OS than those of pivotal clinical trials.
Background
The prognosis of patients with non-small cell lung cancer (NSCLC) who develop leptomeningeal metastasis (LM) is poor.
Objective
To assess the clinical efficacy of osimertinib, a ...third-generation tyrosine-kinase inhibitor (TKI), in patients with epidermal growth-factor receptor (
EGFR
)-mutated NSCLCs and LM.
Patients and Methods
Retrospective study of NSCLC patients with osimertinib-treated
EGFR
-mutated NSCLC and LM.
Results
Twenty patients (mean age, 61.2 years; 70% women) with adenocarcinoma NSCLC were included in the study.
EGFR
mutations were reported in exons 18 (
n
= 2), 19 (
n
= 7), and 21 (
n
= 11). Before starting osimertinib, patients had received a mean of 2.3 treatment lines. When LM was diagnosed, all patients had clinical symptoms. Sixteen (80%) patients had a performance status ≥2. At osimertinib initiation, 13 (65%) patients harbored the
EGFR
-T790M–resistance mutation. Osimertinib was started at 80 (
n
= 17), 160 (
n
= 2), or 40 mg/day (
n
= 1). All 13 (100%) patients with the T790M mutation and 4 (57%) of those without it obtained clinical responses. Among the 11 radiologically assessable patients, 9 (82%) responded, with 5 responses reported within 15 days after treatment initiation. Median overall survival and progression-free survival were 18.0 and 17.2 months, respectively, from the start of osimertinib.
Conclusions
In this non-selected population, osimertinib had remarkable efficacy in NSCLC patients with LM irrespective of the presence of the
EGFR
-T790M–resistance mutation. Osimertinib efficacy was rapid in several patients, even some with poor performance status.
