Stage IIIA Non-Small Cell Lung Cancer Treatment and Outcomes: A Single Institution Retrospective Analysis.
Article in Thoracic cancer, 2025. 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
objectivesStage III non-small cell lung cancer (NSCLC) treatment remains challenging, with a multitude of treatment options available. We assessed Stage IIIA NSCLC outcomes by treatment received.
methodsWe performed a single-institution retrospective review of NSCLC patients with Stage IIIA disease treated January 01, 2010-March 01, 2022. Demographics, treatments, outcomes, and failure patterns were collected. Progression-free survival (PFS) and overall survival (OS) were assessed using Kaplan-Meier analysis. Failure patterns were assessed for differences using chi-square analysis.
resultsOf 270 Stage III NSCLC patients, 134 had Stage IIIA disease with a median follow-up of 29.9 months and a median age of 66 years (IQR 60-75). 66 (49.3%) patients were male, and 105 (78.4%) were current/former smokers (with 30 median pack-years). Patients were treated with definitive radiation with/without chemotherapy (CRT; n = 77, 57.5%), surgery with neoadjuvant chemotherapy and/or radiation (Neoadj; n = 42, 31.3%), and surgery without neoadjuvant therapy (Surg; n = 15, 11.2%). Median PFS was 25.4 months (95% CI 12.5-42.6) for CRT, 22.6 months (95% CI 12.2-44.4) for Neoadj, and 22.8 months (95% CI 5.2-NA) for Surg with no significant intergroup difference (p = 0.99). Median OS was 57.0 months (95% CI 37.4-77.5) for CRT, 51.5 months (95% CI 36.7-65.5) for Neoadj, and 35.3 months (95% CI 16.8-NR) for Surg with no significant intergroup difference (p = 0.99).
conclusionsIn this single institution retrospective study, we find no significant differences in PFS, OS, and failure patterns between patients with Stage IIIA NSCLC treated with definitive (chemo)radiation and surgery with or without neoadjuvant therapy. Further work in the immunotherapy era is needed.
