RESUMO
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.

Pembrolizumab plus chemotherapy is currently used in the first-line treatment of advanced non-small-cell lung cancer without EGFR mutations or ALK rearrangements, regardless of PD-L1 expression status. A study comparing chemotherapy plus pembrolizumab versus pembrolizumab alone has never been performed in patients with PD-L1 ≥50%. The aim of this trial is to perform such a comparison as first-line treatment in patients not eligible for locally advanced treatment who have expression of PD-L1 on ≥50% of tumor cells. The expected results are a reduction in the risk of early progression. A higher objective tumor response is also expected with the combination of chemotherapy and pembrolizumab compared with pembrolizumab alone. The study will allow a direct comparison of the proportion of patients who derive long-term benefit from the treatment. Clinical trial number: EudraCT (2020-002626-86); ClinicalTrials.gov (NCT04547504).
Lay abstract Non-small-cell lung cancer (NSCLC) is the most frequent type of lung cancer. Most NSCLC patients are diagnosed with advanced disease and only 1015% of them are alive after 5 years. In the absence of specific tumor mutations, the currently recommended treatment is a combination of chemotherapy and immunotherapy with the monoclonal antibody pembrolizumab. The goal of immunotherapy is to prevent cancer from evading the immune system by interacting with molecules expressed at the surface of tumor cells (PD-L1) or immune cells (PD-1). A study comparing chemotherapy plus pembrolizumab versus pembrolizumab alone has never been performed in patients with a high level of PD-L1 expression on tumor cells. Therefore we designed the PERSEE study to compare these treatments in advanced-stage NSCLC patients with PD-L1 expression on ≥50% of tumor cells.

BACKGROUND: Topotecan is currently the only drug approved in Europe in a second-line setting for the treatment of small-cell lung cancer. This study investigated whether the doublet of carboplatin plus etoposide was superior to topotecan as a second-line treatment in patients with sensitive relapsed small-cell lung cancer. METHODS: In this open-label, randomised, phase 3 trial done in 38 hospitals in France, we enrolled patients with histologically or cytologically confirmed advanced stage IV or locally relapsed small-cell lung cancer, who responded to first-line platinum plus etoposide treatment, but who had disease relapse or progression at least 90 days after completion of first-line treatment. Eligible patients were aged 18 years or older and had an Eastern Cooperative Oncology Group performance status 0-2. Enrolled patients were randomly assigned (1:1) to receive combination carboplatin plus etoposide (six cycles of intravenous carboplatin [area under the curve 5 mg/mL per min] on day 1 plus intravenous etoposide [100 mg/m2 from day 1 to day 3]) or oral topotecan (2·3 mg/m2 from day 1 to day 5, for six cycles). Randomisation was done using the minimisation method with biased-coin balancing for ECOG performance status, response to the first-line chemotherapy, and treatment centre. The primary endpoint was progression-free survival, which was centrally reviewed and analysed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT02738346. FINDINGS: Between July 18, 2013, and July 2, 2018, we enrolled and randomly assigned 164 patients (82 in each study group). One patient from each group withdrew consent, therefore 162 patients (81 in each group) were included in the intention-to-treat population. With a median follow-up of 22·7 months (IQR 20·0-37·3), median progression-free survival was significantly longer in the combination chemotherapy group than in the topotecan group (4·7 months, 90% CI 3·9-5·5 vs 2·7 months, 2·3-3·2; stratified hazard ratio 0·57, 90% CI 0·41-0·73; p=0·0041). The most frequent grade 3-4 adverse events were neutropenia (18 [22%] of 81 patients in the topotecan group vs 11 [14%] of 81 patients in the combination chemotherapy group), thrombocytopenia (29 [36%] vs 25 [31%]), anaemia (17 [21%] vs 20 [25%]), febrile neutropenia (nine [11%] vs five [6%]), and asthenia (eight [10%] vs seven [9%]). Two treatment-related deaths occurred in the topotecan group (both were febrile neutropenia with sepsis) and no treatment-related deaths occurred in the combination group. INTERPRETATION: Our results suggest that carboplatin plus etoposide rechallenge can be considered as a reasonable second-line chemotherapy option for patients with sensitive relapsed small-cell lung cancer.

INTRODUCTION: A tyrosine-kinase inhibitor (TKI) is indicated as a first-line treatment for patients with non-small-cell lung cancer (NSCLC) harboring an epidermal growth-factor - receptor (EGFR) mutation. Chemotherapy (ChT) given in combination with an EGFR-TKI in this setting is of interest. METHODS: We conducted a meta-analysis of phase III randomized trials comparing EGFR-TKI + ChT vs. EGFR-TKI alone as first-line therapy for advanced NSCLC harboring an activating EGFR mutation. RESULTS: Three studies evaluated gefitinib + ChT (NEJ009, GAP-Brain, and Noronha et al.) and another evaluated osimertinib + ChT (FLAURA-2). Those four eligible studies included 1413 patients with non-squamous NSCLCs, 826 (58%) with an exon-19 deletion (ex19del) and 541 (38%) with EGFRL858R. The EGFR-TKI + ChT combination was significantly associated with prolonged PFS (hazard ratio [HR]: 0.52 [95% confidence interval (CI): 0.45-0.59]; p < 0.0001) and OS (HR: 0.69 [0.52-0.93]; p = 0.01). PFS was particularly improved for patients with brain metastases (HR: 0.41[0.33-0.51]; p < 0.00001). CONCLUSIONS: For patients with untreated, advanced, EGFR-mutated NSCLCs, the EGFR-TKI + ChT combination, compared to EGFR-TKI alone, was associated with significantly prolonged PFS and OS. However, further studies are needed to identify which patients will benefit the most from the combination. REGISTRATION: PROSPERO CRD42024508055.

BACKGROUND: The management of stage III non-small-cell lung cancer (NSCLC) remains heterogeneous and complex, even after the approval of immune checkpoint inhibitors post-chemoradiotherapy (CRT). This observational study from France evaluated real-world practices in managing stage III NSCLC. METHODS: Between 2020 and 2022, we conducted a physician practice survey in 41 medical centers across France, and retrospectively analyzed aggregated information from 417 consecutive charts of patients with stage III NSCLC. We collected information on diagnostic and staging procedures, biomarker testing, surgical and non-surgical treatments, and follow-up. RESULTS: According to the physician survey, diagnostic workup of stage III NSCLC primarily relied on positron emission tomography/computed tomography and brain magnetic resonance imaging, performed for the majority of patients in 100 % and 78 % of centers, respectively. Of 417 patient charts, 414 were evaluable with 53 % of patients having stage IIIA disease, 37 % IIIB, and 10 % IIIC. The most common node involvement was N2 (59 %). Programmed death-ligand 1 testing was conducted for 98 % of patients. Invasive staging (mediastinoscopy or endobronchial ultrasound) was performed in 41 % of patients, of whom 83 % had N2 or N3 nodal involvement. Surgical resection was offered to 120 patients (29 %), with 85 % achieving R0 resection. In 292 charts of patients with unresectable stage III NSCLC, 190 patients (65 %) were offered CRT followed by consolidation immunotherapy. Within these patients, concurrent CRT was more frequently employed (52 %) than sequential CRT (13 %). CONCLUSIONS: Diagnostic procedures and treatment modalities in French medical centers generally align with clinical guidelines for stage III NSCLC, except for invasive staging that was less commonly performed than expected.

Purpose: The third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), osimertinib, is an effective first-line therapy for patients with common EGFR mutation-positive non-small cell lung cancer (NSCLC). However, almost all patients become resistant to treatment. In some patients, emergence of tertiary EGFR mutations is implicated as a resistance mechanism. This study describes patients with NSCLC who acquired the rare EGFR mutations, L718Q or G724S, following EGFR TKI treatment. Patients and Methods: This was a retrospective, observational study undertaken in France from Feb-Nov 2021, in patients with EGFR mutation-positive NSCLC with an acquired L718Q or G724S mutation. Primary objectives were description of tumor characteristics, progression, and progression under treatment. Results: Nine eligible patients were identified. Acquired resistance to initial EGFR TKI treatment was associated with T790M emergence in six patients, who then received osimertinib monotherapy. Overall, eight patients received osimertinib monotherapy treatment at some point (average treatment duration: 18.3 months). Following the emergence of L718Q or G724S, patients received chemotherapy (n = 4; two of whom subsequently received afatinib), nivolumab (n = 2), afatinib (n = 2), or immunochemotherapy (n = 1). In the four patients who received afatinib after identification of L718Q or G724S, 2 achieved a partial response, one had stable disease and one had progressive disease. Treatment duration was 1.6-31.7 months. In patients with controlled disease (n = 3), progression-free survival was 6.1-31.7 months. Two of these patients had previously received osimertinib. Conclusion: Currently, there is no consensus regarding the treatment of EGFR mutation-positive NSCLC following emergence of the osimertinib resistance mutations, L718Q or G724S. Afatinib appears to be a promising treatment option in this setting.
RESUMO
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.
RESUMO
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.

INTRODUCTION: Predictors for mortality and toxicity in older patients with cancer are mainly studied in cohorts with various cancers at different stages. This study aims to identify predictive geriatric factors (PGFs) for early death and severe chemotherapy related adverse events (CRAEs) in patients aged ≥70 years with metastatic non-small-cell lung cancer (mNSCLC). MATERIAL AND METHODS: This is a secondary analysis of the multicenter, randomized, phase 3 ESOGIA trial that compared, for patients ≥70 years with mNSCLC, a treatment algorithm based on performance status and age to another algorithm based on geriatric assessment. To identify PGFs of three-month mortality and grade 3, 4, or 5 CRAEs, multivariate Cox models and logistic models, adjusted for treatment group and center, and stratified by randomization arm, were constructed. RESULTS: Among 494 included patients, 145 (29.4%) had died at three months and 344 (69.6%) had severe chemotherapy toxicity. For three-month mortality, multivariate analyses retained mobility (Test Get up and Go), instrumental activity of daily living (IADL) dependence and weight loss as PGFs. The combined effect of IADL ≤2/4 and weight loss ≥3 kg was strongly associated with three-month mortality (adjusted hazard ratio: 5.71 [95% confidence interval [CI]: 2.64-12.32]). For chemotherapy toxicity, Charlson Comorbidity Index ≥2 was independently associated with grade3, 4, or 5 CRAEs (adjusted odds ratio [95% CI]: 1.94 [1.06-3.56]). DISCUSSION: Mobility, IADL dependence, and weight loss were predictive of three-month mortality in a population aged ≥70 years treated for mNSCLC, while comorbidities were independently associated with severe chemotherapy toxicity.
RESUMO
Outside clinical trials, few data are available on the effect of long-term first-line pembrolizumab in patients with advanced non-small-cell lung cancers with ≥50% of tumor cells expressing programmed cell death ligand 1 (PD-L1). This French, multicenter study included consecutive advanced patients with non-small-cell lung cancer given first-line pembrolizumab alone between May 2017 (authorization date for this indication) and November 2019 (authorization date for pembrolizumab-chemotherapy combination). Information was collected from patients' medical files, with a local evaluation of the response and progression-free survival (PFS). Overall survival (OS) was calculated from pembrolizumab onset using the Kaplan-Meier method. The analysis concerned 845 patients, managed in 33 centers: median age: 65 (range: 59-72) years, 67.8% men, 78.1% Eastern Cooperative Oncology Group performance status 0/1, 38.9%/51.5%/6.6% active, ex or never-smokers, respectively, 10.9%/16.8% taking or recently took corticosteroids/antibiotics, 69.6% nonsquamous histology, 48.9% ≥75% PD-L1-positive, and 20.8% had brain metastases at diagnosis. After a median (95% CI) follow-up of 45 (44.1-45.9) months, respective median (95% CI) PFS and OS lasted 8.2 (6.9-9.2) and 22 (8.5-25.9) months; 3-year PFS and OS rates were 25.4% and 39.4%, respectively. Multivariate analysis retained never-smoker status, adenocarcinoma histology, Eastern Cooperative Oncology Group performance status ≥2, and neutrophil/lymphocyte ratio >4 as being significantly associated with shorter survival, but not brain metastases at diagnosis or <75% PD-L1 tumor-cell expression. These long-term results of pembrolizumab efficacy based on a nationwide "real-world" cohort reproduced those obtained in clinical trials.
RESUMO
BACKGROUND: The median age of newly diagnosed patients with non-small cell lung cancer (NSCLC) is 67 years, and one-third of patients are older than 75 years. Elderly patients are more vulnerable to the adverse effects of chemotherapy, and targeted therapy might thus be a relevant alternative. The objective of this study was to assess the cost-effectiveness of erlotinib followed by chemotherapy after progression, compared to the reverse strategy, in fit elderly patients with advanced NSCLC participating in a prospective randomized phase 2 trial (GFPC0504). METHODS: Outcomes (PFS and overall survival) and costs (limited to direct medical costs, from the third-party payer perspective) were prospectively collected until second progression. Costs after progression and health utilities (based on disease states and grade 3-4 toxicities) were derived from the literature. RESULTS: Median overall survival, QALY and total costs for the erlotinib-first strategy were respectively 7.1 months, 0.51 and 27 734 , compared to 9.4 months, 0.52 and 31 688 for the chemotherapy-first strategy. The Monte Carlo simulation demonstrates that the two strategies do not differ statistically. CONCLUSION: In terms of cost effectiveness, in fit elderly patients with NSCLC, erlotinib followed by chemotherapy compares well with the reverse strategy.

Brigatinib is a next-generation ALK inhibitor (ALKi) that shows efficacy in ALK inhibitor naïve and post-crizotinib ALK+ advanced NSCLCs (aNSCLCs). The efficacy of brigatinib was retrospectively assessed in patients with aNSCLCs included in the brigatinib French Early-Access Program (1 August 2016−21 January 2019). The primary endpoint was investigator-assessed progression-free survival (invPFS) and the primary analysis was updated in 2021 with a longer follow-up, focused on post-brigatinib lorlatinib efficacy. Sixty-six centers included 183 patients: median age 60 ± 12.7 years; 78.3% never/former smokers; median of 3 ± 1 previous lines and 2 ± 0.5 ALKis; 37.1% ECOG PS 2 and 55.6% >3 metastatic sites. The median follow-up from brigatinib initiation was 40.4 months (95% CI 38.4−42.4). InvPFS was 7.4 months (95% CI 5.9−9.6), median duration of treatment (mDOT) was 7.3 months (95% CI 5.8−9.4) and median overall survival (mOS) was 20.3 months (95% CI 15.6−27.6). The median DOT and OS from brigatinib initiation tend to decrease with the number of ALK inhibitors used in previous lines of therapy. Based on the data collected, 92 (50.3%) patients received ≥1 agent(s) post-brigatinib and 68 (73.9%) of them received lorlatinib, with 51 (75%) immediately receiving it post-brigatinib, 12 (17.6%) receiving it after one and 5 (7.4%) after ≥2 subsequent treatments. The median follow-up was 29.9 (95% CI 25.7−33.1) months. Lorlatinib mDOT was 5.3 (95% CI 3.6−7.6) months with a median OS from lorlatinib initiation of 14.1 (95% CI 10.3−19.2) months. The results of the brigALK2 study confirm the efficacy of brigatinib in a population of heavily pretreated ALK+ aNSCLC patients and provide new data on the activity of lorlatinib after brigatinib.
RESUMO
Background: Long-term changes in lung cancer (LC) patients are difficult to evaluate. We report results from the French KBP-2020 real-life cohort. Methods: KBP-2020 was a prospective cohort that included all patients diagnosed with LC in 2020, in nonacademic public hospital in France. Patient and tumour characteristics were described and compared with similarly designed cohorts in 2000 and 2010. Findings: In 2020, 82 centers included 8,999 patients diagnosed with LC. The proportion of women increased: 34·6% (3114/8999) compared to, 24·3% (1711/7051) and 16·0% (904/5667) in 2010 and 2000 (p<0·0001). The proportion of non-smokers was higher in 2020 (12·6%, 1129/8983) than in previous cohorts (10·9% (762/7008) in 2010; 7·2% (402/5586) in 2000, p<0·0001). In 2020, at diagnosis, 57·6% (4405/7648) of patients had a metastatic/disseminated stage non-small-cell lung cancer (NSCLC) (58·3% (3522/6046) in 2010; 42·6% (1879/4411) in 2000, p<0·0001). Compared with 2000 and 2010 data, early survival improved slightly. In 2020, 3-month mortality of NSCLC varied from 3·0% [2·2 - 3·8] for localized to 9·6% [8·1 - 11·0] for locally advanced to 29·2% [27·8 - 30·6] for metastatic and was 24·8% [22·3 - 27·3] for SCLC. Interpretation: To our knowledge KBP cohorts have been the largest, prospective, real-world cohort studies involving LC patients conducted in worldwide. The trend found in our study shows an increase in LC in women and still a large proportion of patients diagnosed at metastatic or disseminated stage. Funding: The study was promoted by the French College of General Hospital Pulmonologists with financial support of industrials laboratories.
RESUMO
INTRODUCTION: Advanced non-squamous non-small cell lung cancer (NsqNSCLC) progressing at the induction of a first-line of platin-based chemotherapy is a subgroup of patients with poor prognosis and few second-line treatment options. MATERIALS AND METHODS: This single-stage phase II prospective multicenter open-label trial performed in platin-based refractory (i.e. progressing during induction phase of first-line platin-based chemotherapy) advanced NsqNSCLC assessed the efficacy of the nintedanib-docetaxel combination in second-line treatment. The primary endpoint was progression-free survival (PFS) rates at 12 weeks with a cut-off at 30% for ineffectiveness and 50% for minimal efficacy. RESULTS: A total of 59 patients from 23 centers were included (mean age, 58.5 years; male gender, 73.6%; performance status 0-1, 100%; former/current smokers, 92.5%; adenocarcinoma, 92.5%, median platin-based first-line chemotherapy, 2). Nintedanib-docetaxel combination was administered for a median of 4 cycles. The rate of PFS at 12 weeks was 39.6% (95% CI, 28.2-56.8). Median PFS was 2.7 (95% CI, 1.4-4.1) months and one-year PFS was 11.8% (95% CI, 4.8-22.2). Median overall survival (OS) was 6.9 (95% CI, 4.3-8.2) months and 12-month OS was 32.1% (95% CI, 19.8-45.0); 18-month OS was 27.6% (95% CI, 16,1-40.4). Twenty-nine (53.7%) patients reported at least one serious treatment-related adverse events leading to permanent discontinuation of at least one study drug in 12 (22.2%) patients. CONCLUSION: The predefined minimal efficacy was not demonstrated. However, a number of NsqNSCLC patients refractory to first-line platin-based chemotherapy appeared to benefit from this combination.

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.
RESUMO
OBJECTIVES: Immune checkpoint inhibitors have become the standard of care for metastatic non-small-cell lung cancer (NSCLC) progressing during or after platinum-based chemotherapy. Real-world clinical practice tends to represent more diverse patient characteristics than randomized clinical trials. We sought to evaluate overall survival (OS) outcomes in the total study population and in key subsets of patients who received nivolumab for previously treated advanced NSCLC in real-world settings in France, Germany, or Canada. MATERIALS AND METHODS: Data were pooled from two prospective observational cohort studies, EVIDENS and ENLARGE, and a retrospective registry in Canada. Patients included in this analysis were aged ≥18 years, had stage IIIB/IV NSCLC, and received nivolumab after at least one prior line of systemic therapy. OS was estimated in the pooled population and in various subgroups using the Kaplan-Meier method. Timing of data collection varied across cohorts (2015-2019). RESULTS: Of the 2585 patients included in this analyses, 1235 (47.8 %) were treated in France, 881 (34.1 %) in Germany, and 469 (18.1 %) in Canada. Median OS for the total study population was 11.3 months (95 % CI: 10.5-12.2); this was similar across France, Germany, and Canada. The OS rate was 49 % at 1â¯year and 28 % at 2 years for the total study population. In univariable Cox analyses, the presence of epidermal growth factor receptor mutations in nonsquamous disease, liver, or bone metastases were associated with significantly shorter OS, whereas tumor programmed death ligand 1 expression and Eastern Cooperative Oncology Group performance status 0-1 were associated with significantly prolonged OS. Similar OS was noted across subgroups of age and prior lines of therapy. CONCLUSION: OS rates in patients receiving nivolumab for previously treated advanced NSCLC in real-world clinical practice closely mirrored those in phase 3 studies, suggesting similar effectiveness of nivolumab in clinical trials and clinical practice.

BACKGROUND: Few data have been published on the clinical and histopathological characteristics of advanced non-small-cell lung cancer (NSCLC) patients with high PD-L1 expression versus intermediate or none and the prognostic value of PD-L1 expression for patients treated with chemotherapy is unknown. This study was undertaken to prospectively assess the prognostic value of tumor-cell (TC) and immune-cell (IC) PD-L1 expressions for advanced NSCLC patients. METHODS: It was a prospective, multicenter study on advanced NSCLC patients, with performance status 0/1, scheduled, consecutively, to receive first-line platin-based chemotherapy. PD-L1 expression was determined immunochemically (Dako Autostainer and monoclonal antibody 22C3) and its impact on progression-free survival (PFS) and overall survival (OS) assessed. RESULTS: Among 198 patients screened in 19 centers, 140 were included median age: 66.5 ± 10 years; 76.4% men; 79.3% Caucasians; 10.7% nonsmokers; 63.6% adenocarcinomas; <1%, 1-50% and ≥50% TC PD-L1-expression rates were 47.1%, 25.7% and 27.2% of patients, respectively; respective null, intermediate and high rates on ICs were 35.7%, 38.6% and 25.7%. Second- and third-line chemotherapies were administered to 58.6% and 26.4% of the patients, respectively. None received immunotherapy. First-, second- and third-line median (95% CI) PFS lasted 4.6 (3.6-5.2), 3.7 (2.3-4.7) and 2.2 (1.5-4.3) months, respectively; median OS was 16.9 (11.4-19.9) months. No significant PFS and OS differences were observed according to TC or IC PD-L1 expression. CONCLUSION: According to the results of this prospective, multicenter study, neither TC nor IC PD-L1 expression appears to be prognostic for chemotherapy-managed advanced NSCLC patients.
RESUMO
Immune-checkpoint inhibitor (ICI) efficacy in patients with non-small cell lung cancer (NSCLC) harboring molecular alterations remains poorly elucidated. This study was undertaken to determine ICI efficacy against epidermal growth-factor receptor (EGFR)/anaplastic lymphoma kinase (ALK)/c-ros oncogene 1 (ROS1)-mutated NSCLC patients in the real-world setting.In this retrospective, multicenter study on adults with ICI-treated EGFR-mutated or ALK- or ROS1-translated NSCLCs, we analyzed clinical characteristics and outcomes: ICI-treatment duration, and progression-free survival (PFS), objective response rate, duration of response, and overall survival (OS) from immunotherapy initiation.Fifty-one NSCLC patients (mean age, 58.0 years) were included from 20 French centers: 61% were never-smokers and 59% were women. Among them, 82% had EGFR-activating mutations, 16% ALK translocations, or 2% ROS1 translocations. Before ICI therapy, patients had received a median of 3 treatment lines (including tyrosine-kinase inhibitor). The median PFS was 2.1 (95% confidence interval [CI], 1.5-3.2) months for the entire cohort, 2.2 (95% CI, 1.4-3.2) for EGFR-mutated patients, and 2.4 (95% CI, 2.1-not reached) months for ALK-translocated patients. The median OS was 14.7 (95% CI, 12.1-19.2) months for the entire population and 13.9 (95% CI, 8.8-20.0) and 19.2 (95% CI, 13.1-not reached) months for EGFR-mutated and ALK-translocated patients, respectively. Seven (13.7%) patients were treated with ICI for >9 months. Toxicities were reported in 22% (11/51), including 8% (4/51) grade ≥3.In this real-world setting, analysis of ICI PFS against EGFR-mutated or ALK-translocated NSCLC patients appeared close to that observed in pretreated unselected NSCLC patients. The more promising OS probably linked to post-ICI treatments. Large prospective studies on these patient subsets are needed.

Dabrafenib plus trametinib combination is approved in Europe for BRAF V600E-mutant metastatic non-small-cell lung cancer (NSCLC). The objective of this study was to assess efficacy and safety of this combination in a real-world setting. This retrospective multicentric study included 40 patients with advanced NSCLC harboring BRAF V600E mutation and receiving dabrafenib plus trametinib. The median progression-free survival (PFS) and overall survival (OS) were 17.5 (95% CI 7.1-23.0) months and 25.5 (95% CI 16.6-not reached) months in the entire cohort, respectively. For the 9 patients with first-line treatment, median PFS was 16.8 (95% CI 6.1-23.2) months and median OS was 21.8 (95% CI 1.0-not reached) months; for the 31 patients with second-line or more treatments, median PFS and OS were 16.8 (95% CI 6.1-23.2) months and 25.5 (95% CI 16.6-not reached) months, respectively. Adverse events led to permanent discontinuation in 7 (18%) patients, treatment interruption in 8 (20%) and dose reduction in 12 (30%). In conclusion, these results suggest that efficacy and safety of dabrafenib plus trametinib combination in patients with BRAF V600E metastatic NSCLC are comparable in a real-world setting and in clinical trials for both previously untreated and treated patients.
RESUMO
INTRODUCTION: Using immune-checkpoint inhibitors (ICIs) to manage cancer is associated with various immune-related adverse events. Central and/or peripheral neurological disorders are rare and potentially serious. We analyzed the characteristics of non-small-cell lung cancer (NSCLC) patients who developed immune-related encephalitis under anti-programmed-death protein-1 or its ligand (PD-1/PD-L1). METHODS: Clinical, biological and radiological characteristics of ICI-treated NSCLC patients with immune-related encephalitis, from 6 centers, were evaluated retrospectively. RESULTS: The 6 centers included 9 patients: all men, all smokers, median (range) age 67 (48-77) years, 78% adenocarcinomas, first- or second-line ICI for 5 and 4 patients, respectively. Two patients had non-active cerebral metastases at ICI onset. A median of 5 (1-22) ICI infusions preceded neurological symptoms, the most frequent being confusion (78%), fever (45%) and cerebellar ataxia (33%). CSF analyses revealed a median white blood cell count of 22/mm3 (1-210/mm3), with hyperlymphocytosis in 8 patients and high protein levels in all. All bacteriological and virological analyses were negative. Cerebral MRI was considered normal for 5 patients; 4 patients had FLAIR hypersignals consistent with brain parenchyma inflammation. Three patients required intensive care. All patients received corticosteroids (different doses), a median of 8.5 (6-18) days post-onset. Corticosteroids achieved rapid symptom regression without sequelae in 8 patients. The last patient, with the longest time until corticosteroid introduction, died. ICIs were never restarted in any patient. CONCLUSION: Immune encephalitis, a rare but serious complication of anti-PD-1/PD-L1 therapy, carries a good prognosis when managed with early corticosteroids.
