Introduction: Compared with docetaxel, the phase-III trial, ULTIMATE, showed a significant improvement of progression-free survival (PFS) with paclitaxel–bevacizumab combination (PB) as second- or third-line treatment in advanced non-small cell lung cancer (NSCLC). With the increase of immunotherapy treatment in first-line settings, the optimal treatment after first-line failure must be redefined. Methods: This multicentric retrospective study identified all advanced NSCLC patients treated with PB as second-line therapy and beyond. The main efficacy outcomes assessed were objective response rate (ORR), disease control rate (DCR), PFS, and overall survival (OS). The adverse events were reported according to Common Terminology Criteria for Adverse Events (CTCAE). Results: From January 2010 to February 2020, 314 patients in 16 centers received the PB combination. Most patients were male (55%), with a median age of 60 years (19–82), 95% had adenocarcinoma, 27% had a performance status ⩾2, 45% had brain metastases at the time of inclusion. They mostly received the PB combination either in second (20%) or in third-line (39%), and 28% were treated just after ICI failure. ORR and DCR were 40% and 77%, respectively; median PFS and OS were 5.7 [interquartile range (IQR): 3.2–9.6] and 10.8 [IQR: 5.3–19.6] months, respectively. All grade adverse events concerned 82% of patients, including 53% asthenia and 39% neurotoxicity, and 25% of patients continued monotherapy (mostly with bevacizumab) alone due to toxicity. Median PFS for patients treated after ICI failure (ICI+) was significantly superior compared with those not previously treated with ICI (ICI−): 7.0 [IQR: 4.2–11.0] versus 5.2 [IQR: 2.9–8.8] months, p = 0.01, without statistically significant difference for OS between these two groups. In multivariate analysis, factors associated with superior PFS were previous ICI treatment and performance status of 0–1. Only a performance status of 0–1 was associated with superior OS. Conclusion: PB combination as second-line treatment or beyond for advanced non-squamous NSCLC had acceptable toxicity and a clinically relevant efficacy and is an option as salvage treatment for these patients, more particularly after ICI progression.

Durvalumab is a humanized monoclonal antibody targeting programmed cell death ligand‐1 (PD‐L1), leading to an antitumor activity, used as consolidation therapy in patients with locally advanced unresectable non‐small cell lung cancer (NSCLC). Several immune‐related adverse events (irAEs) have previously been described in patients following treatment with immune checkpoint inhibitors (ICIs). To the best of our knowledge, we report the first case of immunotherapy‐induced fully reversible bronchiolitis and bronchiectasis, despite the fact that its pathophysiological mechanism has been previously considered to be irreversible. Here we report a case of durvalumab‐induced lesions of bronchiolitis and fully reversible bronchiectasis. This immune‐related adverse event has not previously been described.

Background: Few epidemiological data are available on surgically treated Caucasian patients with non-small-cell lung cancers (NSCLCs) harboring epidermal growth factor receptor (EGFR) mutations. The main objective of this study was to describe, in the real-world setting, these patients’ incidence, clinical, and tumoral characteristics. Methods: The participating centers included all consecutive localized non-squamous NSCLC patients undergoing surgery between January 2018 and December 2019 in France. EGFR status was determined retrospectively when not available before surgery. Results: The study includes 1391 no squamous NSCLC patients from 16 centers; EGFR status was determined before surgery in 692 (49.7%) of the cases and conducted as part of the study for 699 (50.3%); 171 (12.3%) were EGFR mutated; median age: 70 (range: 36–88) years; female: 59.6%; never smokers: 75.7%; non-squamous histology 97.7%, programmed death ligand-1 expression 0%/1–49%/⩾50 in 60.5%/25.7%/13.8%, respectively. Surgery was predominantly lobectomy (81%) or segmentectomy (14.9%), with systematic lymph node dissection in 95.9%. Resection completeness was R0 for 97%. Post-surgery staging was as follows: IA: 52%, IB: 16%, IIA: 4%, IIB: 10%, IIIA: 16%, and IIIB: 0.05%; EGFR mutation exon was Del19/exon 21 (L858R)/20/18 in 37.4%/36.8%/14%, and 6.4% of cases, respectively; 31 (18%) patients received adjuvant treatment (chemotherapy: 93%, EGFR tyrosine kinase inhibitor: 0%, radiotherapy: 20%). After a median follow-up of 31 (95% confidence interval: 29.6–33.1) months, 45 (26%) patients relapsed: 11/45 (24%) locally and 34 (76%) with metastatic progression. Median disease-free survival (DFS) and overall survival were not reached and 3-year DFS was 60%. Conclusion: This real-world analysis provides the incidence and outcomes of resected EGFR-mutated NSCLCs in a European patient cohort.

Background: The role and timing of whole or stereotaxic brain radiotherapy (BR) in patients with advanced non-small cell lung cancer (aNSCLC) and asymptomatic brain metastases (aBMs) are not well established. This study investigates whether deferring BR until cerebral progression was superior to upfront BR for patients with aNSCLC and aBM. Methods: This open-label, multicenter, phase III trial, randomized (1:1) aNSCLC patients with aBMs to receive upfront BR and chemotherapy: platin–pemetrexed and bevacizumab in eligible patients, followed by maintenance pemetrexed with or without bevacizumab, BR arm, or the same chemotherapy with BR only at cerebral progression, chemotherapy (ChT) arm. Primary endpoint was progression-free survival (PFS), secondary endpoints were overall survival (OS), global, extra-cerebral and cerebral objective response rate (ORR), toxicity, and quality of life [ClinicalTrials.gov identifier: NCT02162537]. Results: The trial was stopped early because of slow recruitment. Among 95 included patients, 91 were randomized in 24 centers: 45 to BR and 46 to ChT arms (age: 60 ± 8.1, men: 79%, PS 0/1: 51.7%/48.3%; adenocarcinomas: 92.2%, extra-cerebral metastases: 57.8%, without differences between arms.) Significantly more patients in the BR-arm received BR compare with those in the ChT arm (87% versus 20%; p < 0.001); there were no significant differences between BR and ChT arms for median PFS: 4.7, 95% confidence interval (CI):3.4–7.5 versus 4.8, 95% CI: 2.4–6.5 months, for median OS: 8.5, 95% CI:.6–11.1 versus 8.3, 95% CI:4.5–11.5 months, cerebral and extra-cerebral ORR (27% versus 13%, p = 0.064, and 30% versus 41%, p = 0.245, respectively). The ChT arm had more grade 3/4 neutropenia than the BR arm (13% versus 6%, p = 0.045); others toxicities were comparable. Conclusion: The significant BR rate difference between the two arms suggests that upfront BR is not mandatory in aNSCLC with aBM but this trial failed to show that deferring BR for aBM is superior in terms of PFS from upfront BR.

Background Immune checkpoint inhibitors (ICIs) have been approved as second‐line therapy for advanced non–small cell lung cancers (NSCLCs) progressing after platinum‐based chemotherapy. However, some patients' disease progressed rapidly and sometimes exhibited explosive tumor progression. This descriptive, prospective study aimed to assess the characteristics of nonresponders with rapid progression (RP), defined as progression‐free survival (PFS) ≤2 or 2‐4 months under ICIs. Methods This analysis included all consecutive ICI‐treated (second‐or‐more line) patients with RP ≤4 months from 1 September 2016 to 31 August 2017 and compared the clinical characteristics, treatments, and outcomes (overall survival [OS]; responses; PFS, according to treatment line) of NSCLCs that progressed after ≤2 vs 2‐4 months on ICIs. Results Comparisons of the 224 (70.2%) patients with ≤2‐month and 95 (29.8%) with 2‐ to 4‐month RP revealed the former had less frequent nonsmokers and ECOG PS = 0, more frequent stage IV disease and higher neutrophil/lymphocyte ratio. Their respective ICI PFS rates were: 1.6 [95% CI: 0.1‐2] and 2.7 [2.0‐4.2] months, with 16.5% and 11.6% having partial responses to first‐ and second‐line therapies post‐ICI chemotherapy. Their respective median OS rates were 6.0 and 9.0 months (P ≤ .009). Multivariate analysis retained only PFS of the first‐line therapy pre‐ICI and neutrophil/lymphocyte ratio at ICI onset as being significantly associated with ≤2‐month RP. Conclusion In the real‐life setting, NSCLC RP on ICI remains a challenge. New descriptive and analytic studies are needed to identify factors predictive of RP. Immune checkpoint inhibitors (ICIs) have been approved as second‐line therapy for advanced non–small cell lung cancers (NSCLCs) progressing after platinum‐based chemotherapy. However, some patients' disease progressed before 2 or 4 months—without any response—and sometimes exhibited explosive tumoral progression. This descriptive prospective study aimed to assess the management and clinical outcomes of nonresponders with rapid progression, defined as progression‐free survival ≤2 or 2‐4 months under ICI.

BackgroundThe optimal treatment duration of ICIs for patients with advanced NSCLC remains uncertain. In phase 3 clinical trials, treatment continued for 2 years or until disease progression with similar long-term survival rates. Real-life data are missing.Patients and methodsThis academic multicentric retrospective study aims at analyzing the characteristics of patients who discontinued treatment after at least 18 months of ICI monotherapy, in the setting of controlled disease.ResultsOf the 1127 patients treated with immunotherapy in the given period in six centers, 107 patients had their tumor controlled after at least 18 months of treatment and 54 (50%) of them had discontinued ICI. The median duration of treatment was 26 months. Treatment was stopped due to prescriber choice or toxicity in 46% and 22% of cases, respectively. After a median follow-up of 21 months from ICI discontinuation (95% CI 15.0–26.1 months), 18 (33%) patients experienced tumor progression after a median time of 10.0 months (range 2–33). From discontinuation, 12-month overall survival (OS) and progression-free survival (PFS) were 90% (95% CI 77.7–95.7) and 71% (95% CI 56.8–81.5), respectively; 24-month OS and PFS were 84% (95% CI 68.7–92.2) and 63% (95% CI 46.1–76.2), respectively. Duration of disease control after ICI discontinuation was correlated with tumor response at treatment discontinuation: PFS rate at 12 months was 76% after complete response (CR n = 11) or partial response (PR n = 37) and 22% after only stable disease (SD n = 6) as best response, p-value = 0.0002. PFS rate at 12 months was 80% for CR and/or complete metabolic response with 18F-FDG PET/CT (CMR) and 65% for others. Fourteen patients out of the 18 relapse patients received a subsequent treatment: seven with ICI rechallenge (best response 14% PR and 86% SD) and five with localized therapy with 60% CR.ConclusionsThis real-life study provides new insight into long-term outcomes of patients with advanced NSCLC treated with ICI for at least 18 months before treatment discontinuation in the absence of PD. Tumor response and CMR with FDG PET just before therapy discontinuation may be a predictive factor of prolonged disease control upon discontinuation. These results call for caution in discontinuing treatment in patients with stable disease as the best response.

BackgroundFew 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.MethodsThis 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.ResultsThe 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.ConclusionIn 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.

Background Few data are available on the impact of venous thrombotic events (VTE) in patients with metastatic non-small cell lung cancer (mNSCLC) treated with immunotherapy. Methods This is a secondary analysis of the ESKEYP study, a national, retrospective, multicenter study that consecutively included all PD-L1 ≥ 50% mNSCLC patients who initiated first-line treatment with pembrolizumab monotherapy. From May 2017 to November 2019, 845 patients were included (from availability of pembrolizumab in this indication in France to the authorization of the combination with chemotherapy). Impact of VTE and patient characteristics were analyzed. Results Of the 748 patients (88.5%) with available data, the incidence of VTE was 14.8% (111/748). At pembrolizumab initiation, Khorana score was ≥ 2 for 55.0% (61/111) of them. Recurrence of VTE was reported for 4 of the 111 patients and 5 had bleeding complications. Patients with VTE were significantly younger, had more frequently long-term corticosteroids treatment and more often liver metastases. Progression-free survival (PFS) was significantly shorter in patients with VTE compared to patients without VTE: 6.1 (95% CI 4.1–9.0) months vs. 8.3 (6.9–10.3) months (p = 0.03). VTE did not significantly impact overall survival (OS): 15.2 (10.0–24.7) months with VTE and 22.6 (18.4–29.8) months without VTE (p = 0.07). In multivariate analysis for PFS and OS, HRs for VTE were 1.3 (0.99–1.71), p = 0.06 and 1.32 (0.99–1.76), p = 0.05. Conclusion The incidence of VTE appears to be as high with in first-line immunotherapy as with chemotherapy in patients with mNSCLC, with in patient with VTE, a no significant trend for lower PFS and OS in multivariate analysis. more marked impact on PFS than on OS.

BackgroundMET-targeted tyrosine kinase inhibitors (TKIs) demonstrated efficacy in advanced non-small cell lung cancer (aNSCLC) with MET exon14 skipping mutations (METexon14); yet, data on the management of these patients in clinical practice is sparse.ObjectiveThe aim of this study was to describe the management of METexon14 aNSCLC patients.Patients and MethodsThis real-life, retrospective study analyzed the management of METexon14 aNSCLC. The primary endpoint was the median overall survival (mOS). Secondary endpoints were to assess investigator–progression-free survival (PFS) and mOS in different subgroups: patients treated with (a) crizotinib, regardless of treatment line; (b) anti-MET TKIs (crizotinib, tepotinib, capmatinib); and (c) immunotherapy.ResultsA total of 118 patients were included between December 2015 and January 1, 2020 in 13 centers. Median age was 73 years, 62.7% were female, 83.9% had adenocarcinoma, 92.4% at stage IV, and 27% had more than three metastatic sites. The majority of the patients (106, 89.8%) received at least one systemic treatment; 73% received at least one anti-MET TKI: crizotinib (68.6%), tepotinib (16%), capmatinib (10%). Only 10% received two anti-MET TKIs in their treatment sequences. With a median follow-up of 16 months (95% CI 13.6–29.7), mOS was 27.1 months (95% CI 18–31.4). There was no significant difference between mOS of patients treated and never treated with crizotinib, 19.7 (95% CI 13.6–29.7) and 28 (95% CI 16.4–NR) months, respectively (p = 0.16); mOS of the TKI cohort and of the TKI-naïve patient cohort were 27.1 (95% CI 18–29.7) and 35.6 (95% CI 8.6–NR) months respectively, with no significant difference (p = 0.7).ConclusionsIn this real-life study, there was no evidence of benefit in mOS with anti-MET TKIs.
