RESUMO
BACKGROUND: Among patients with resectable early-stage non-small-cell lung cancer (NSCLC), a perioperative approach that includes both neoadjuvant and adjuvant immune checkpoint inhibition may provide benefit beyond either approach alone. METHODS: We conducted a randomized, double-blind, phase 3 trial to evaluate perioperative pembrolizumab in patients with early-stage NSCLC. Participants with resectable stage II, IIIA, or IIIB (N2 stage) NSCLC were assigned in a 1:1 ratio to receive neoadjuvant pembrolizumab (200 mg) or placebo once every 3 weeks, each of which was given with cisplatin-based chemotherapy for 4 cycles, followed by surgery and adjuvant pembrolizumab (200 mg) or placebo once every 3 weeks for up to 13 cycles. The dual primary end points were event-free survival (the time from randomization to the first occurrence of local progression that precluded the planned surgery, unresectable tumor, progression or recurrence, or death) and overall survival. Secondary end points included major pathological response, pathological complete response, and safety. RESULTS: A total of 397 participants were assigned to the pembrolizumab group, and 400 to the placebo group. At the prespecified first interim analysis, the median follow-up was 25.2 months. Event-free survival at 24 months was 62.4% in the pembrolizumab group and 40.6% in the placebo group (hazard ratio for progression, recurrence, or death, 0.58; 95% confidence interval [CI], 0.46 to 0.72; P<0.001). The estimated 24-month overall survival was 80.9% in the pembrolizumab group and 77.6% in the placebo group (P = 0.02, which did not meet the significance criterion). A major pathological response occurred in 30.2% of the participants in the pembrolizumab group and in 11.0% of those in the placebo group (difference, 19.2 percentage points; 95% CI, 13.9 to 24.7; P<0.0001; threshold, P = 0.0001), and a pathological complete response occurred in 18.1% and 4.0%, respectively (difference, 14.2 percentage points; 95% CI, 10.1 to 18.7; P<0.0001; threshold, P = 0.0001). Across all treatment phases, 44.9% of the participants in the pembrolizumab group and 37.3% of those in the placebo group had treatment-related adverse events of grade 3 or higher, including 1.0% and 0.8%, respectively, who had grade 5 events. CONCLUSIONS: Among patients with resectable, early-stage NSCLC, neoadjuvant pembrolizumab plus chemotherapy followed by resection and adjuvant pembrolizumab significantly improved event-free survival, major pathological response, and pathological complete response as compared with neoadjuvant chemotherapy alone followed by surgery. Overall survival did not differ significantly between the groups in this analysis. (Funded by Merck Sharp and Dohme; KEYNOTE-671 ClinicalTrials.gov number, NCT03425643.).

Molecular diagnosis on nasopharyngeal swabs (NPS) is the current standard for COVID-19 diagnosis, but saliva may be an alternative specimen to facilitate access to diagnosis. We compared analytic performances, feasibility and acceptability of NPS, saliva, and oral-self sampling swab for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A prospective, multicenter study was conducted in military hospitals in France among adult outpatients attending COVID-19 diagnosis centers or hospitalized patients. For each patient, all samples were obtained and analyzed simultaneously with RT-PCR or transcription-mediated amplification method. Clinical signs, feasibility, and acceptability for each type of sample were collected. A total of 1220 patients were included, corresponding to 1205 NPS and saliva and 771 OS. Compared to NPS, the sensitivity, specificity, and kappa coefficient for tests performed on saliva were 87.8% (95% CI 83.3-92.3), 97.1% (95% CI 96.1-98.1), and 0.84 (95% CI 0.80-0.88). Analytical performances were better in symptomatic patients. Ct values were significantly lower in NPS than saliva. For OS, sensitivity was estimated to be 61.1% (95% CI 52.7-69.4) and Kappa coefficient to be 0.69 (95% CI 0.62-0.76). OS was the technique preferred by the patients (44.3%) before saliva (42.4%) and NPS (13.4%). Instructions were perceived as simple by patients (> 90%) for saliva and OS. Finally, the painful nature was estimated to be 0.9 for OS, on a scale from 0 to 10, and to be 5.3 for NPS. Performances of OS are not sufficient. Saliva is an acceptable alternative to NPS for symptomatic patient but the process required additional steps to fluidize the sample.

INTRODUCTION: Preliminary reports indicated that smokers could be less susceptible to coronavirus SARS-CoV-2, which causes Covid-19. However, once infected an increased risk of severe disease is reported. We investigated the association between smoking and COVID-19 during an outbreak of the disease on a naval vessel. METHODS: We conducted a cross-sectional, observational study on the 1769 sailors of the same navy aircraft carrier at sea exposed at the same time to SARS-CoV2 to investigate the link between tobacco consumption and Covid-19. RESULTS: Among the 1688 crewmembers (87% men; median age = 28 [interquartile range 23-35]) included, 1279 (76%) developed Covid-19 (1038 [62%] reverse-transcriptase- polymerase chain reaction testing-positive and 241 [14%] with only clinical signs). One hundred and seven patients were hospitalized. The univariable analysis odds ratio (OR) for Covid-19 infection was 0.59 (95% confidence interval [CI], 0.45-0.78; p < .001) for current smokers versus former and nonsmokers; sex, body mass index or blood group had no significant impact. Crewmembers >50 years old had an increased risk of contracting Covid-19 (OR, 2.84 [95% CI, 1.30-7.5]; p = .01). Multivariable analysis retained the lower risk of current smokers becoming infected (OR, 0.64 [0.49-0.84]; p < .001) and age >50 years was significatively associated with Covid-19 (OR, 2.6 [1.17-6.9]; p = .03). CONCLUSIONS: Current smoking status was associated with a lower risk of developing Covid-19 but cannot be considered as efficient protection against infection. The mechanism of the lower susceptibility of smokers to SARS-CoV-2 requires further research. TRIAL REGISTRATION: IRB no.: 0011873-2020-09. IMPLICATIONS: (1) Recent epidemiologic data suggest a paradoxical link between smoking and COVID-19. (2) Among the 1688 crewmembers (with an attack rate of 76% and exposed at the same time in the same place to SARS-CoV2), we found a significantly lower risk for developing COVID-19 in current smokers (71%) versus former and nonsmokers (80%). This finding strongly supports the need for further research on nicotine physiological pathway and its impact on COVID-19 infection whilst emphasizing that tobacco smoking should not be considered as efficient protection against COVID-19.

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: There is no recommended therapy for malignant pleural mesothelioma that has progressed after first-line pemetrexed and platinum-based chemotherapy. Disease control has been less than 30% in all previous studies of second-line drugs. Preliminary results have suggested that anti-programmed cell death 1 (PD-1) monoclonal antibody could be efficacious in these patients. We thus aimed to prospectively assess the anti-PD-1 monoclonal antibody alone or in combination with anti-cytotoxic T-lymphocyte protein 4 (CTLA-4) antibody in patients with malignant pleural mesothelioma. METHODS: This multicentre randomised, non-comparative, open-label, phase 2 trial was done at 21 hospitals in France. Eligible patients were aged 18 years or older with an Eastern Cooperative Oncology Group performance status of 0-1, histologically proven malignant pleural mesothelioma progressing after first-line or second-line pemetrexed and platinum-based treatments, measurable disease by CT, and life expectancy greater than 12 weeks. Patients were randomly allocated (1:1) to receive intravenous nivolumab (3 mg/kg bodyweight) every 2 weeks, or intravenous nivolumab (3 mg/kg every 2 weeks) plus intravenous ipilimumab (1 mg/kg every 6 weeks), given until progression or unacceptable toxicity. Central randomisation was stratified by histology (epithelioid vs non-epithelioid), treatment line (second line vs third line), and chemosensitivity to previous treatment (progression ≥3 months vs <3 months after pemetrexed treatment) and used a minimisation method with a 0·8 random factor. The primary outcome was the proportion of patients who achieved 12-week disease control, assessed by masked independent central review; the primary endpoint would be met if disease control was achieved in at least 40% of patients. The primary endpoint was assessed in the first 108 eligible patients. Efficacy analyses were also done in the intention-to-treat population and safety analyses were done in all patients who received at least one dose of their assigned treatment. This trial is registered at ClinicalTrials.gov, number NCT02716272. FINDINGS: Between March 24 and August 25, 2016, 125 eligible patients were recruited and assigned to either nivolumab (n=63) or nivolumab plus ipilimumab (n=62). In the first 108 eligible patients, 12-week disease control was achieved by 24 (44%; 95% CI 31-58) of 54 patients in the nivolumab group and 27 (50%; 37-63) of 54 patients in the nivolumab plus ipilimumab group. In the intention-to-treat population, 12-week disease control was achieved by 25 (40%; 28-52) of 63 patients in the nivolumab group and 32 (52%; 39-64) of 62 patients in the combination group. Nine (14%) of 63 patients in the nivolumab group and 16 (26%) of 61 patients in the combination group had grade 3-4 toxicities. The most frequent grade 3 adverse events were asthenia (one [2%] in the nivolumab group vs three [5%] in the combination group), asymptomatic increase in aspartate aminotransferase or alanine aminotransferase (none vs four [7%] of each), and asymptomatic lipase increase (two [3%] vs one [2%]). No patients had toxicities leading to death in the nivolumab group, whereas three (5%) of 62 in the combination group did (one fulminant hepatitis, one encephalitis, and one acute kidney failure). INTERPRETATION: Anti-PD-1 nivolumab monotherapy or nivolumab plus anti-CTLA-4 ipilimumab combination therapy both showed promising activity in relapsed patients with malignant pleural mesothelioma, without unexpected toxicity. These regimens require confirmation in larger clinical trials. FUNDING: French Cooperative Thoracic Intergroup.

BACKGROUND: Radiochemotherapy without surgical resection has become the treatment of choice for anal squamous-cell carcinoma. The optimal treatment for rectal squamous-cell carcinoma is not well established. OBJECTIVE: The purpose of this work was to assess the efficacy of nonoperative strategies in the management of primary rectal squamous-cell carcinoma. DESIGN: We retrospectively reviewed data from all of the patients with documented rectal squamous-cell carcinoma who were treated with conservative strategies in a single institution. Concomitant radiochemotherapy was proposed to all except 1 patient. The remaining patient was treated by radiotherapy alone given his impaired functional status. All of the patients were treated with conformal or intensity-modulated radiation therapy. Surgical resection was reserved for persistent disease or relapse. SETTING: This study was conducted in a single tertiary institution. MAIN OUTCOME MEASURES: After a mean follow-up of 56 months, 2 patients experienced relapse and no patients died. RESULTS: Eleven patients were included in the series. The clinical response to radiotherapy was complete for 7 patients. The remaining 4 patients underwent salvage surgery. The pathologic response was incomplete for 2 of the 4 patients. One recurrence occurred outside the field of radiotherapy and was successfully treated by radiotherapy. The second was a local recurrence, which occurred on a patient who was treated with radiotherapy alone. LIMITATIONS: The number of patients included in this retrospective series was limited because of the rarity of the disease. Patients were treated with nonhomogeneous conservative strategies because of modification in the therapeutic strategy for anal squamous-cell carcinoma and of the adaptation of the treatment to patient comorbidities and functional status. CONCLUSIONS: This series demonstrates that good results can be obtained by using a rectum-conserving strategy. Close follow-up should be maintained, with the use of salvage surgery reserved only for persistent disease or relapse (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A155).

The FDG-PET (fluorine-18 fluorodeoxyglucose positron emission tomography) scan is used with increasing frequency to investigate pleural abnormalities and to determine the possibility of neoplastic invasion. However, false-positive findings are not uncommon and talc pleurodesis has been reported to cause hypermetabolic pleural thickenings up to 5 years after the procedure. We report the cases of 3 patients (2 of whom had a history of asbestos exposure) requiring talc pleurodesis for recurrent pneumothoraces between 1988 and 1990, who were investigated in 2011 for pleural abnormalities. Avid pleural thickening on FDG-PET scan mimicking pleural cancer was found, but this was deemed secondary to the pleurodesis. Talc pleurodesis generates inflammation which promotes pleural adhesions. This inflammatory reaction could decrease with time, as in other inflammatory processes. Since talc is not metabolized by the body, the FDG-PET scan can remain positive, most likely because of a foreign-body granulomatous reaction, even 20 years later. It is important to be aware of this possibility and to question patients with pleural abnormalities about past procedures and mention such procedures to the colleagues who are responsible for interpreting metabolic imaging. Follow-up of hypermetabolic pleural lesions attributed to talc pleurodesis is important for the detection of new pleural lesions or neoplastic evolution.

UNLABELLED: The concept that ultrasonography could be interesting in the prehospital setting and during the transfer of traumatized patients is not new. Paradoxically, there is a lack of description of routine use of ultrasonography in emergency ambulances. The aim of this study was to compare the feasibility and efficiency of an extended focused assessment sonography for trauma (eFAST) examination performed on-site, during the patient's transfer, or both. MATERIALS AND METHODS: From February 2010 to June 2012, 30 prehospital emergency physicians were divided randomly into 3 groups. Group 1 performed an ultrasound examination on-site; group 2, during patient transfer; and group 3, in both settings. The eFAST examination was systematically performed in all severe traumas. RESULTS: Ninety-eight patients were included. Forty-four eFAST examinations were performed on-site only; 33, only during transport; and 21, in both settings. The feasibility was 95.4%, 93.9%, and 95.2%, respectively, and efficiency, 95%, 97%, and 100%, respectively. There was no significant difference in performance or duration whether the examination was performed on-site, during the transfer, or both (w = 0.68). Last but not least, in 2 cases in group 3, the second examination carried out during transfer showed new results with the occurrence of intraperitoneal effusion in one case and a pleural effusion in the other. CONCLUSIONS: The eFAST examination can provide reliable and important information in the initial evaluation of traumatized patients. It can be completed either on-site or during patient transfer. Its feasibility and efficiency are similar to that done in intensive units, especially if the examination is repeated.

BACKGROUND: First-line standard-of-care for unresectable, pleural mesothelioma (PM) changed with the phase 3 CheckMate 743 study results, showing that nivolumab plus ipilimumab (Nivo + Ipi) significantly extended overall survival (OS) versus platinum + pemetrexed chemotherapy for PM (median OS 18.1 versus 14.1 months; hazard ratio: 0.74; p = 0.002). Efficacy and safety data in real-world (rw) settings are needed to confirm these results. METHODS: This French multicenter, retrospective cohort study was undertaken to assess the outcomes of treatment-naïve PM patients given Nivo + Ipi via an early-access program (EAP). The primary objective was investigator-assessed real world -progression-free survival (PFS). The secondary objectives were the combination's -overall survival (OS) and safety. RESULTS: From 1 April 2021 to 15 Feb 2022, the analysis included 201 of the 305 EAP-enrolled patients treated in 63 centers (79.6 % men; median age: 75 years; 91.8 % Eastern Cooperative Oncology Group performance status (ECOG-PS) 0/1; 74.5 % epithelioid histology). With median (95 % CI) follow-up for all patients of 18.4 (17.7-19.2) months, -PFS and OS were 6.3 (5.3-7.5) and 18.9 (17.6-not reached (NR)) months, with 1-year OS at 66.4 % (60.1-73.3 %). Median OS and 1-year survival rates were 21.0 (18.7-NR) and 70.8 % (63.9 %-780.6 %), and 14.1 (10.9-21.0) months and 54.9 % (42.8 %-70.4 %) for epithelioid and non-epithelioid PM subgroups, respectively. PFS was equal between the two subgroups. Grade 3-4 adverse events occurred in 23.3 % of patients and three deaths were treatment-related. CONCLUSIONS: For this unselected PM population, efficacy and safety outcomes compared favorably with CheckMate 743 trial results.

BACKGROUND: In an open-label multicenter non-randomized non-comparative phase II study in patients with stage IIIB/IV non-squamous non-small cell lung cancer (NSCLC), oncogenic addiction (EGFR mutation or ALK/ROS1 fusion), with disease progression after tyrosine-kinase inhibitor and no prior chemotherapy (NCT04042558), atezolizumab, carboplatin, pemetrexed with or without bevacizumab showed some promising result. Beyond the clinical evaluation, we assessed safety and patient-reported outcomes (PROs) to provide additional information on the relative impact of adding atezolizumab to chemotherapy with and without bevacizumab in this population. MATERIALS: Patients received platinum-pemetrexed-atezolizumab-bevacizumab (PPAB cohort) or, if not eligible, platinum-pemetrexed-atezolizumab (PPA cohort). The incidence, nature, and severity of adverse events (AEs) were assessed. PROs were evaluated using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-Core 30 and EORTC QLQ-Lung Cancer 13). RESULT: Overall, 68 (PPAB) and 72 (PPA) patients were evaluable for safety. Grade 3-4 AEs occurred in 83.8% (PPAB) and 63.9% (PPA). Grade 3-4 atezolizumab-related AEs occurred in 29.4% and 19.4%, respectively. Grade 3-4 bevacizumab-related AEs occurred in 36.8% (PPAB). Most frequent grade 3-4 AEs were neutropenia (19.1% in PPAB; 23.6% in PPA) and asthenia (16.2% in PPAB; 9.7% in PPA). In PPAB, we observed a global stability in global health security (GHS) score, fatigue and dyspnea with a constant tendency of improvement, and a significant improvement in cough. In PPA, we observed a significant improvement in GHS score with a significant improvement in fatigue, dyspnea and cough. At week 54, we observed an improvement from baseline in GHS score for 49.2% of patients. In both cohorts, patients reported on average no clinically significant worsening in their overall health or physical functioning scores. CONCLUSION: PPAB and PPA combinations seem tolerable and manageable in patients with stage IIIB/IV non-squamous NSCLC with oncogenic addiction (EGFR mutation or ALK/ROS1 fusion) after targeted therapies.

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: Management of stage-III-N2 non-small-cell lung cancer (NSCLC) based on a multimodal strategy (surgery or radiotherapycombined with systemic drugs) remains controversial. Patients are treated with a curative intent, and available data suggestprolonged survival after complete resection. However, no consensual definition of "tumor resectability" exists. This study aimed to analyze the concordanceamong French tumor board meeting (TBM)-emittedtherapeutic decisions forstage-III-N2 NSCLC. METHODS: Six patients with stage-III-N2 NSCLC discussed at Saint-Etienne University Hospital'sthoracic TBMs were selected, anonymouslyreported, and submitted to the participating TBMs. The primary goal of this multicenter, prospective, observational study was to assess the consistency of TBMpanel decisions for each case. The secondary endpointwas identifying the demographic or technical factors that potentiallyaffected decision-making. RESULTS: Twenty-seven TBMs from university hospitals, a cancer center, general hospitals, and a private hospitalparticipated in this study. None of their decisions for the six cases were unanimous.The decisions were homogenous for three cases (78%, 85%, and 88% TBMs opted for medical treatment, respectively),andmore ambivalent for the other three (medical versus surgical strategies were favored by 44%/56%, 46%/54%, and 58%/42% TBMs, respectively). Interestingly, decisions regarding chemoradiationand perioperative chemotherapyinthe medical and surgical strategies, respectively, were also discordant. Hospital type, specialist participation in TBMs, and activity volumes were not significantly associated with therapeutic decisions. CONCLUSION: The results of this study highlight substantial disparities amongFrench TBMs regarding therapeutic management of stage-III-N2 NSCLC. The decisions were not associated with local conditions.

OBJECTIVE: To evaluate the safety and efficacy of second-line metronomic oral vinorelbine-atezolizumab combination for stage IV non-small-cell lung cancer. METHODS: This was a multicenter, open-label, single-arm Phase II study performed in patients with advanced NSCLC without activating EGFR mutation or ALK rearrangement who progressed after first-line platinum-doublet chemotherapy. Combination treatment was atezolizumab (1200 mg IV day 1, every 3 weeks) and oral vinorelbine (40 mg, 3 times by week). The primary outcome was progression-free survival (PFS) during the 4-month follow-up from the first dose of treatment. Statistical analysis was based on the exact single-stage Phase II design defined by A'Hern. Based on literature data, the Phase III trial threshold was set at 36 successes in 71 patients. RESULTS: 71 patients were analyzed (median age, 64 years; male, 66.2%; ex-smokers/active smokers, 85.9%; ECOG performance status 0-1, 90.2%; non-squamous NSCLC, 83.1%; PD-L1 ≥ 50%, 4.4%). After a median follow-up of 8.1 months from treatment initiation, 4-month PFS rate was 32% (95% CI, 22-44), i.e. 23 successes out 71 patients. OS rate was 73.2% at 4 months and 24.3% at 24 months. Median PFS and OS were 2.2 (95% CI, 1.5-3.0) months and 7.9 (95% CI, 4.8-11.4) months, respectively. Overall response rate and disease control rate at 4 months were 11% (95% CI, 5-21) and 32% (95% CI, 22-44), respectively. No safety signal was evidenced. CONCLUSION: Metronomic oral vinorelbine-atezolizumab in the second-line setting did not achieve the predefined PFS threshold. No new safety signal was reported for vinorelbine-atezolizumab combination.

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
BACKGROUND: Smoking kills 8 million people a year worldwide. It is the most prevalent cause of death in France by cancer, cardiovascular, or respiratory diseases. Minimal advice consists in asking patients who smoke if they are interested in quitting. It is effective in reducing smoking. The French High Health Authority recommends its systematic use with patients, whatever their reason for seeking treatment. The beneficial effect of spirometry on smoking cessation is controversial. The objective of our study was to measure the consequences of spirometry associated with minimal advice, compared with only minimal advice in soldiers seen during a routine medical examination. METHODS: Our prospective, longitudinal, open, multicenter, controlled, randomized study was conducted among French military smokers presenting for an occupational medicine visit. Each participant received, depending on their group (intervention or control), either minimal advice associated with an evaluation of lung function by mini-spirometer, or only minimal advice. Follow-up visits were performed at 6 and 12 months. The primary objective was self-reported tobacco use cessation at 6 months. RESULTS: A total of 267 participants (126 in the intervention group and 141 for the control arm) were included in 10 centers between June 2019 and June 2020. The response rate was 75.6% at 6 months. The cessation rates were 17% and 18% in the intervention and control groups, respectively, with no significant difference between the two groups (P = 0.9). The cessation rate in the general population was 13% at 6 months. CONCLUSIONS: Spirometry does not seem to influence smoke cessation on a military population at 6 months. The overall cessation rate in our study was well in excess of the 3-6% expected from only providing minimal which is underused in general practice and should be encouraged.
RESUMO
BACKGROUND: Previous reports showed limited efficacy of immune checkpoint inhibitors as single-agent treatment for non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutation or ALK/ROS1 fusion. We aimed at evaluating the efficacy and safety of immune checkpoint inhibitor combined with chemotherapy and bevacizumab (when eligible) in this patient subgroup. METHODS: We conducted a French national open-label multicentre non-randomised non-comparative phase II study in patients with stage IIIB/IV NSCLC, oncogenic addiction (EGFR mutation or ALK/ROS1 fusion), with disease progression after tyrosine kinase inhibitor and no prior chemotherapy. Patients received platinum, pemetrexed, atezolizumab, bevacizumab (PPAB cohort) or, if not eligible to bevacizumab, platinum-pemetrexed-atezolizumab (PPA cohort). The primary end-point was the objective response rate (RECIST v1.1) after 12 weeks, evaluated by blind independent central review. RESULTS: 71 patients were included in PPAB cohort and 78 in PPA cohort (mean age, 60.4/66.1 years; women 69.0%/51.3%; EGFR mutation, 87.3%/89.7%; ALK rearrangement, 12.7%/5.1%; ROS1 fusion, 0%/6.4%, respectively). After 12 weeks, objective response rate was 58.2% (90% confidence interval [CI], 47.4-68.4) in PPAB cohort and 46.5% (90% CI, 36.3-56.9) in PPA cohort. Median progression-free survival and overall survival were 7.3 (95% CI 6.9-9.0) months and 17.2 (95% CI 13.7-NA) months in PPAB cohort and 7.2 (95% CI 5.7-9.2) months and 16.8 (95% CI 13.5-NA) months in PPA cohort, respectively. Grade 3-4 adverse events occurred in 69.1% of patients in PPAB cohort and 51.4% in PPA cohort; Grade 3-4 atezolizumab-related adverse events occurred in 27.9% and 15.3%, respectively. CONCLUSION: Combination approach with atezolizumab with or without bevacizumab and platinum-pemetrexed achieved promising activity in metastatic EGFR-mutated or ALK/ROS1-rearranged NSCLC after tyrosine kinase inhibitor failure, with acceptable safety profile.

The ROS-1 gene plays a major role in the oncogenesis of numerous tumors. ROS-1 rearrangement is found in 0.9-2.6% of non-small-cell lung cancers (NSCLCs), mostly lung adenocarcinomas, with a significantly higher rate of women, non-smokers, and a tendency to a younger age. It has been demonstrated that ROS-1 is a true oncogenic driver, and tyrosine kinase inhibitors (TKIs) targeting ROS-1 can block tumor growth and provide clinical benefit for the patient. Since 2016, crizotinib has been the first-line reference therapy, with two-thirds of the patients' tumors responding and progression-free survival lasting ~20 months. More recently developed are ROS-1-targeting TKIs that are active against resistance mechanisms appearing under crizotinib and have better brain penetration. This review summarizes current knowledge on ROS-1 rearrangement in NSCLCs, including the mechanisms responsible for ROS-1 oncogenicity, epidemiology of ROS-1-positive tumors, methods for detecting rearrangement, phenotypic, histological, and molecular characteristics, and their therapeutic management. Much of this work is devoted to resistance mechanisms and the development of promising new molecules.
