    L admission des patients atteints de cancer du poumon en réanimation fait toujours débat. Le mauvais pronostic de ces patients est souvent mis en avant.Tous les patients consécutifs atteints de cancer du poumon et séjournant plus de 24h en réanimation entre janvier 2003 et décembre 2010 ont été inclus dans une étude rétrospective. 104 patients ont été inclus avec un SAPS 2 médian de 54,5 ; 52% étaient métastatiques à l admission en réanimation. 55 (53%) patients ont été intubés et ventilés de manière invasive. Les taux de mortalité en réanimation, à l hôpital, à 1 an et 3 ans sont respectivement de 31,7%, 48%, 83,7%, 98%. Les facteurs de mauvais pronostic mis en évidence sont le score SAPS 2 >= 42 (OR 2,65 IC 95% (1,10-6,36), p=0,03), la ventilation mécanique (OR 4,88 IC 95% (1,86- 12,76), p=0,012), l utilisation des vasopresseurs (OR 6,26 IC95% (2,52- 15,57), p<0,001) et la nécessité d une suppléance d organe (ventilation non-invasive, ventilation mécanique invasive, vasopresseurs, dialyse) (OR 5,5 IC95% (1,12- 27,2), p=0,0002). 75% des patients sortis vivants de l hôpital après l hospitalisation en réanimation auront un traitement spécifique du cancer du poumon.Le pronostic du patient atteint de cancer du poumon hospitalisé en réanimation dépend de la gravité de la pathologie qui l amène en réanimation et non de sa maladie sous-jacente.PARIS6-Bibl.Pitié-Salpêtrie (751132101) / SudocSudocFranceF

    International audienceBackground: Osimertinib is an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) used in first line for the treatment of advanced EGFR-mutated non-small cell lung cancer (NSCLC). Objective: The identification of related histomolecular resistance mechanisms to first-line osimertinib is a critical step to define the optimal treatment strategy beyond progression. Patients and Methods: All consecutive patients treated in the first line with osimertinib for advanced EGFR-mutated NSCLC at 10 hospitals in the Greater Paris area between April 2015 and January 2021 were included. Histomolecular data from plasma and tissue samples taken at progression under osimertinib were collected, and all samples were analyzed using DNA next-generation sequencing. Data on objective response rate (ORR), overall survival (OS), progression-free survival (PFS), and time to treatment discontinuation (TTD) were also collected. Results: Overall, 104 patients were included. Most patients had adenocarcinoma (n = 102, 98%) with an exon 19 EGFR deletion (n = 54, 52%). Forty-two patients (50%) had central nervous system (CNS) metastasis at the time of osimertinib initiation. ORR was 76%, median PFS and OS were 12.6 months and 52 months, respectively, and TTD was 33 months. At the time of analysis, 44 patients (42%) had tumor progression, and among these patients, 27 (61%) contributive samples were available. The most frequent molecular alterations at progression were mesenchymal epithelial transition factor (MET) amplification (15%; n = 4) and EGFR C797S mutation (11%; n = 3). Histological transformation was found in one patient (4%). RNA next-generation sequencing was performed in eight patients and showed a CCDC6-RET fusion in one patient (12%). Conclusions: We confirmed the efficacy of osimertinib in patients with advanced EGFR mutation-positive NSCLC. At progression, the most frequent histomolecular alterations were MET amplification and EGFR C797S mutation

    Brigatinib is a next-generation ALK inhibitor (ALKi) that shows efficacy in ALK inhibitor na&iuml;ve 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&ndash;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 &plusmn; 12.7 years; 78.3% never/former smokers; median of 3 &plusmn; 1 previous lines and 2 &plusmn; 0.5 ALKis; 37.1% ECOG PS 2 and 55.6% &gt;3 metastatic sites. The median follow-up from brigatinib initiation was 40.4 months (95% CI 38.4&ndash;42.4). InvPFS was 7.4 months (95% CI 5.9&ndash;9.6), median duration of treatment (mDOT) was 7.3 months (95% CI 5.8&ndash;9.4) and median overall survival (mOS) was 20.3 months (95% CI 15.6&ndash;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 &ge;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 &ge;2 subsequent treatments. The median follow-up was 29.9 (95% CI 25.7&ndash;33.1) months. Lorlatinib mDOT was 5.3 (95% CI 3.6&ndash;7.6) months with a median OS from lorlatinib initiation of 14.1 (95% CI 10.3&ndash;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

    International audienceBrigatinib 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.
