Efficacy and safety of induction chemoimmunotherapy in older patients with unresectable stage III NSCLC: a real-world multicenter study.
Article in Therapeutic advances in medical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: The benefit of adding immunotherapy to induction chemotherapy before definitive chemoradiotherapy (CRT) in older patients with unresectable stage III non-small-cell lung cancer (NSCLC) remains unclear. Objectives: This real-world study aimed to evaluate the efficacy and safety of induction chemoimmunotherapy followed by CRT in this patient population. Design: A real-world multicenter study. Methods: In this retrospective, multicenter study, we enrolled patients aged ⩾65 years with unresectable stage III NSCLC who received CRT between January 2014 and June 2024. Patients were stratified into two groups: the induction chemoimmunotherapy group (I-CRT), who received PD-1/PD-L1 inhibitors plus chemotherapy before CRT, and the control group (Non-I-CRT), who received CRT without any prior immunotherapy. Propensity score matching (PSM) was used to balance baseline characteristics. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Results: Among 260 patients, 141 received I-CRT and 119 constituted the Non-I-CRT control group. After 1:1 PSM (97 patients per group), the I-CRT group showed significantly improved outcomes compared to the Non-I-CRT group: median PFS was 23.4 versus 11.6 months ( Conclusion: Induction chemoimmunotherapy before CRT is feasible in selected older NSCLC patients, offering survival benefits without significant safety concerns.
