Immune-checkpoint inhibitor (ICI) efficacy in patients with NSCLC harboring molecular alterations remains poorly elucidated. This study was undertaken to determine ICI efficacy against BRAF-, HER2-, ...MET-, and RET-NSCLC in a real-world setting.
In this retrospective, multicenter study in ICI-treated BRAF-, HER2-, MET- or RET-NSCLCs, we analyzed clinical characteristics and outcomes: ICI-treatment duration, progression-free survival (PFS), objective response rate, duration of response, and overall survival (OS).
There were 107 patients with NSCLC (mean age, 65.5 y) included from 21 centers: 37% were never-smokers, 54% were men, and 93% had adenocarcinoma. Among them, 44 had BRAF mutation (V600: 26), 23 had HER2 mutation, 30 had MET mutation, and nine had RET translocation. Programmed cell death ligand 1 (PD-L1) status was known for 70 patients and was greater than or equal to 1% in 34 patients. Before ICI, patients had received a median of one treatment line. Median duration of response, PFS, and OS were 15.4 (95% confidence interval CI: 12.6–not reached NR) months, 4.7 (95% CI: 2.3–7.4) months, and 16.2 (95% CI: 12.0–24.0) months, respectively, for the entire cohort. The response rates for BRAF-V600, BRAF–non-V600, HER2, MET, and RET-altered NSCLC were 26%, 35%, 27%, 36%, and 38%, respectively. For patients who were PD-L1 negative and those who were PD-L1 positive, PFS was 3.0 (95% CI: 1.2–NR) and 4.3 (95% CI: 2.1–8.5) months, respectively, and OS was 11.7 (95% CI: 4.1–NR) and 35.8 (95% CI: 9.0–35.2) months, respectively. Toxicities were reported in 28 patients (26%), including 11 patients (10%) with a grade greater than or equal to three.
In this real-world setting, ICI efficacy against patients with BRAF-, HER2-, MET-, or RET-NSCLC seemed close to that observed in unselected patients with NSCLC. Large prospective studies on these subsets of patients are needed.
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.
Summary Background The molecular profiling of patients with advanced non-small-cell lung cancer (NSCLC) for known oncogenic drivers is recommended during routine care. Nationally, however, the ...feasibility and effects on outcomes of this policy are unknown. We aimed to assess the characteristics, molecular profiles, and clinical outcomes of patients who were screened during a 1-year period by a nationwide programme funded by the French National Cancer Institute. Methods This study included patients with advanced NSCLC, who were routinely screened for EGFR mutations, ALK rearrangements, as well as HER2 (ERBB2), KRAS, BRAF, and PIK3CA mutations by 28 certified regional genetics centres in France. Patients were assessed consecutively during a 1-year period from April, 2012, to April, 2013. We measured the frequency of molecular alterations in the six routinely screened genes, the turnaround time in obtaining molecular results, and patients' clinical outcomes. This study is registered with ClinicalTrials.gov , number NCT01700582. Findings 18 679 molecular analyses of 17 664 patients with NSCLC were done (of patients with known data, median age was 64·5 years range 18–98, 65% were men, 81% were smokers or former smokers, and 76% had adenocarcinoma). The median interval between the initiation of analysis and provision of the written report was 11 days (IQR 7–16). A genetic alteration was recorded in about 50% of the analyses; EGFR mutations were reported in 1947 (11%) of 17 706 analyses for which data were available, HER2 mutations in 98 (1%) of 11 723, KRAS mutations in 4894 (29%) of 17 001, BRAF mutations in 262 (2%) of 13 906, and PIK3CA mutations in 252 (2%) of 10 678; ALK rearrangements were reported in 388 (5%) of 8134 analyses. The median duration of follow-up at the time of analysis was 24·9 months (95% CI 24·8–25·0). The presence of a genetic alteration affected first-line treatment for 4176 (51%) of 8147 patients and was associated with a significant improvement in the proportion of patients achieving an overall response in first-line treatment (37% 95% CI 34·7–38·2 for presence of a genetic alteration vs 33% 29·5–35·6 for absence of a genetic alteration; p=0·03) and in second-line treatment (17% 15·0–18·8 vs 9% 6·7–11·9; p<0·0001). Presence of a genetic alteration was also associated with improved first-line progression-free survival (10·0 months 95% CI 9·2–10·7 vs 7·1 months 6·1–7·9; p<0·0001) and overall survival (16·5 months 15·0–18·3 vs 11·8 months 10·1–13·5; p<0·0001) compared with absence of a genetic alteration. Interpretation Routine nationwide molecular profiling of patients with advanced NSCLC is feasible. The frequency of genetic alterations, acceptable turnaround times in obtaining analysis results, and the clinical advantage provided by detection of a genetic alteration suggest that this policy provides a clinical benefit.

Background
The KEYNOTE‐024 trial demonstrated that pembrolizumab, a PD‐1 inhibitor, significantly improves progression‐free survival (PFS) and overall survival (OS) in selected patients with ...previously untreated advanced non–small cell lung cancer (NSCLC) with a PD‐L1 tumor proportion score (TPS) ≥50% and without EGFR/ALK aberrations. The main aim of this study was to report the efficacy and safety profile of pembrolizumab in real‐life conditions.
Method
This was a French retrospective multicenter longitudinal study of 108 consecutive patients with advanced NSCLC, a PD‐L1 TPS ≥50% and without EGFR/ALK aberrations who were treated by pembrolizumab, in first line. Patient data were obtained from medical files.
Results
The main characteristics of the cohort were: median age range 66.7 37‐87 years, 64.8% male, 23.1% with a performance status (PS) of 2, and 88.9% current or former smokers. Eighty‐seven percent had stage IV NSCLC at diagnosis, 9.2% untreated brain metastases at inclusion,. With a median follow‐up of 8.2 months, the median PFS was 10.1 months (95% CI, 8.8‐11.4). The objective response rate was 57.3% (complete response 2.7%, partial response 54.6%). Disease control rate was 71.1%. At 6 months, the OS rate estimated was 86.2%. Treatment‐related adverse events (AE) of grade 3 occurred in 8% of patients. There were no grade 4 or 5 AEs.
Conclusion
In a real‐life cohort of advanced NSCLC patients (including PS 2 and untreated brain metastases), with PD‐L1 TPS ≥50%, pembrolizumab demonstrates similar PFS to the pivotal clinical trial.
This retrospective multicenter longitudinal study was intended to report the efficacy and safety profile of pembrolizumab in real‐life conditions for the first‐line treatment of advanced squamous none small‐cell lung cancer. The median progression free survival was 10.1 months (95% CI, 8.8‐11.4) and the treatment‐related adverse events of grade 3 occurred in 8% of patients. This study demonstrates similar progression‐free survival to KEYNOTE‐024.
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.
Data regarding characteristics, safety and survival outcomes of patients aged 80 or older treated with immune checkpoint inhibitors (ICI) in routine oncology practice are limited.
We retrospectively ...collected data of patients aged 80 and older with advanced non-small cell lung cancer (NSCLC) or melanoma treated with anti-PD1, anti-PD-L1 or anti-CTLA-4 regardless of the treatment line, in 14 institutions, between January 2014 and June 2017. Progression-free survival (PFS) and overall survival (OS) were estimated with the Kaplan Meier method. Toxicity was assessed according to CTCAE 5.0. Multivariate analyses were performed with the Cox model.
Eighty-two patients were included (36 with NSCLC, 45 with melanoma). Their median age was 82 years (range 80-93). Nivolumab and pembrolizumab were mainly used. In the NSCLC group, median PFS and OS were 2.3 months (95%CI 1.8-6.1) and 8.8 months (95%CI 5.5-18.1), respectively. In the melanoma group, median PFS and OS were 10.2 months (95%CI 4.5-20.0) and 24.5 months (95%CI 14.1-NR), respectively. The albumin level was found to be independently associated with a better OS in both groups. Grade 3-4 toxicities occurred in 15 patients (18.5%). One patient died from ICI-induced pulmonary toxicity.
Our study findings suggest that treatment with ICI in elderly patients with NSCLC and melanoma has a risk-benefit ratio that supports its use. However, we report in this cohort that one in five patients has a grade 3-4 IRAEs leading to treatment discontinuation. Geriatric assessment prior to initiation of therapy and during therapy should be routine in patients aged 80 years and older.
•Small cell lung cancer (SCLC) is a highly aggressive type of lung cancer.•Atezolizumab plus chemotherapy improves overall survival in 1st-line treatment of extensive SCLC.•IFCT-1905 CLINATEZO ...studied consecutive patients receiving this regimen in France.•Our studyreproduced in a real life setting thekey survival outcomesof the landmark trial.
Small cell lung cancer (SCLC) has a tendency towards recurrence and limited survival. Standard-of-care in 1st-line is platinum-etoposide chemotherapy plus atezolizumab or durvalumab,based on landmarkclinical trials.
IFCT-1905 CLINATEZO is a nationwide, non-interventional, retrospectivestudy of patients with extensive-SCLC receivingatezolizumab plus chemotherapy as part of French Early Access Program. Objectives were to analyse effectiveness,safetyand subsequent treatments.
The population analyzed included 518 patients who received atezolizumabin 65 participating centers. There were 66.2% male,mean age was 65.7 years; 89.1% had a performance status (PS) 0/1 and 26.6% brain metastases. Almost all(95.9%) were smokers. Fifty-five (10.6%) received at least 1 previous treatment. Median number of atezolizumab injections was 7.0 (range 1.0–48.0) for a median duration of 4.9 months (95% CI 4.5–5.1). Atezolizumab was continued beyond progression in 122 patients (23.6%) for a median duration of 1.9 months (95% CI: 1.4–2.3). Best objective response was complete and partialin 19 (3.9%) and 378 (77.1%)patients. Stable diseasewas observed in 50 patients (10.2%). Median follow-up was30.8 months (95% CI: 29.9–31.5). Median overall survival (OS), 12-, 24-month OS rates were 11.3 months (95% CI: 10.1–12.4), 46.7% (95% CI 42.3–50.9) and 21.2% (95% CI 17.7–24.8). Median real-world progression-free survival, 6-, 12-month rates were 5.2 months (95% CI 5.0–5.4), 37.5% (95% CI 33.3–41.7) and 15.2% (95% CI 12.2–18.6). For patients with PS 0/1, median OS was 12.2 months (95% CI 11.0–13.5). For patients with previous treatment, median OS was 14.9 months (95% CI 10.1–21.5). Three-hundred-and-twenty-six patients(66.4%) received subsequent treatment and27 (5.2%) were still underatezolizumabat date of last news.
IFCT-1905 CLINATEZO shows reproductibility, in real-life,ofIMpower-133survival outcomes, possibly attributed to selection of patients fit for this regimen, adoption of pragmatic approaches,including concurrent radiotherapy and treatment beyond progression.
•The study included advanced non-squamous NSCLC refractory to 1st-line chemotherapy.•Progression as best response during platin-based chemotherapy first line defined refractory state.•Efficacy of ...nintedanib-docetaxel combination for 2nd-line treatment was assessed.•One-year PFS was 11.8%; 12 and 18-months OS were 32.1% and 27.6% respectively.•A subpopulation of these refractory patients seems to benefit from this combination.
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.
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.
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.
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.
•In 681 non-squamous aNSCLC PD-L1 ≥ 50 % patients, 12.5 % had a KRAS G12C mutation.•No clinical or biological difference between KRAS G12C and KRAS non-G12C patients.•KRAS G12C had no impact on ...first-line pembrolizumab efficacy in non-squamous aNSCLC.
Few data are available on the impact of KRAS mutation in patients with advanced non-squamous non-small cell lung cancer (aNSCLC) treated with immunotherapy. This analysis assessed the impact of KRAS mutation on the efficiency of first-line pembrolizumab immunotherapy in aNSCLC patients with PD-L1 ≥ 50 %.
This was a secondary analysis of the ESCKEYP study, a retrospective, national, multicenter study which included consecutively all metastatic NSCLC patients who initiated first-line treatment with pembrolizumab monotherapy from May 2017 (date of pembrolizumab availability in this indication in France) to November 22, 2019 (pembrolizumab-chemotherapy combination approval). Progression-free survival (PFS) and overall survival (OS) were calculated from the start of pembrolizumab treatment by the Kaplan-Meier method. Tumor response and PFS were assessed locally.
Among the 681 non-squamous aNSCLC PD-L1 ≥ 50 % patients treated with pembrolizumab in the first line, 227 (33.0 %) had a KRAS mutation (KRAS G12C, 12.5 %; KRAS non-G12C, 20.5 %). Except among non-smokers (KRAS G12C, 0 %; KRAS non-G12C, 2.9 %; no KRAS mutation, 9.2 %), patients presented no differences in terms of sex, age, number and sites of metastatic disease at diagnosis, use of corticosteroids, use of antibiotics, and for biological factors between wild-type KRAS, KRAS G12C and non-KRAS G12C groups. Median (95 % CI) PFS in months were 7.0 (3.7–14) for KRAS G12C, 4.8 (3.4–6.7) for KRAS non-G12C and 8.5 (7.3–10.6) for wild-type KRAS genotypes (p = 0.23). Median OS were 18.4 (12.6-NR), 20.6 (11.4-NR) and 27.1 (18.7–34.2) months, respectively (p = 0.57).
No difference in efficacy was observed in non-squamous aNSCLC patients treated with first-line pembrolizumab immunotherapy whether they presented a KRAS G12C, non KRAS G12C or wild-type KRAS genotype.
•In France, epidermal growth factor receptor mutations are present in 12.9% of the resected stage I-II.•Epidermal growth factor receptor mutations have no impact on disease-free survival and overall ...survival.•Patients with resected stage I-II non-small cell lung cancer have a 5-year Disease-Free Survival of 65% and a 5-year overall survival of 75%.
Molecular profile of resected stage I–II non-small cell lung cancer (NSCLC) would help refine prognosis and personalize induction or adjuvant strategies. We sought to report the molecular profile of resected stage I–II NSCLC and analyzed the impact of epidermal growth factor receptor (EGFR) mutations on outcomes in a Western population.
Surgical cases were identified from Biomarkers France study, a nationwide prospective study including NSCLC patients screened for EGFR, HER2, KRAS, BRAF, PIK3CA, ALK alterations from 2012 to 2013. Among surgical patients, clinical charts of the largest centers were reviewed in order to analyze the prognostic impact of EGFR mutations.
In the BMF database (n = 17.636), surgical patients (n = 854) were characterized by a higher proportion of EGFR mutations than nonsurgical patients (12.9% vs. 10.2%, P = .025), while the other molecular alterations did not differ. The proportion of EGFR mutations was 27% in women undergoing surgery. In the study group (n = 293; EGFR wild type, n = 235; usual mutation, n = 50; rare mutation, n = 8), after a median follow-up of 67 months, 215 patients (74.4%) had not relapsed. No difference was found between EGFR-mutant and EGFR-wt tumors regarding recurrence site, disease-free survival, and overall survival. The 5-year disease-free survival and overall survival after surgical resection of stage I-II EGFR-mutated tumors were 65% and 75%, respectively.
In resected stage I to II NSCLC, EGFR mutations were found in 12.9% of cases, associated with a 5-year overall survival of 75%, with no impact on recurrence site, disease-free survival, and overall survival.
Molecular profile of localized non-small cell lung cancer has not been reported in Western Europe. In the nationwide Biomarker France study, EGFR mutations were found in 12.9% of resected stage I-II NSCLC, associated with 5-year DFS of 65% and 5-year OS of 75%. No difference was found between EGFR-mutant and EGFR-wt tumors regarding recurrence site, disease-free survival, and overall survival.
