Efficacy and safety of immuno-chemotherapy in patients with advanced non-small-cell lung cancer harboring oncogenic mutations: a multicenter retrospective study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe effect of immuno-chemotherapy on patients with advanced non-small-cell lung cancer (NSCLC) harboring oncogenic mutations remains poorly understood. This study aimed to characterize the efficacy of immuno-chemotherapy and determine the optimal treatment strategy for such patients.
methodsWe conducted this retrospective cohort study on patients with NSCLC harboring oncogenic driver alterations and treated with an immune checkpoint inhibitor combined with chemotherapy at five institutions. The clinical characteristics and outcomes of immuno-chemotherapy for NSCLC with oncogenic mutations in a real-world setting were analyzed.
resultsAmong 846 patients diagnosed with advanced or recurrent NSCLC between April 2017 and April 2021, 43 patients with oncogenic mutations were treated with immuno-chemotherapy. The median age of patients was 68 (range 44-78) years; 42% of patients never smoked, and adenocarcinoma was the most common histology (95%). In patients with KRAS mutations (n = 10) or PD-L1 expression of 50% or greater (n = 10), the disease control rate was 100%. The median progression-free survival (PFS) was 5.4, 6.3, and 8.9 months in patients harboring mutations in EGFR, KRAS, and other genes, respectively (P = 0.22). Patients with PD-L1 expression of 50% or greater had significantly longer median PFS than patients with PD-L1 expression of less than 50% (16.4 vs. 5.1 months; P = 0.001). Two patients experienced grade 3 immuno-related adverse events.
conclusionImmuno-chemotherapy has a clinical benefit and is safe for patients with oncogenic mutations. Notably, patients with PD-L1 expression of 50% or more experience greater benefit from immuno-chemotherapy than those with PD-L1 expression of less than 50%.
