Survival Outcomes in Patients With Locally Advanced NSCLC Converted to Resectable Disease by Neoadjuvant Therapy.

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/
aimNeoadjuvant therapy enables disease conversion to resectability in selected patients with locally advanced non-small-cell lung cancer (NSCLC) but real-world survival outcomes in this setting are not well defined. This study aimed to evaluate survival outcomes and prognostic factors in patients with initially unresectable, non-metastatic NSCLC in whom complete resection was achieved following neoadjuvant therapy. PATIENTS AND
methodsThis retrospective cohort study included 35 pa tients with initially unresectable NSCLC who underwent R0 resection after neoadjuvant therapy. Demographic, clinical, radiological, and pathological characteristics, treatment details, and survival outcomes were collected. Factors associated with event-free (EFS) and overall (OS) survival were analyzed.
resultsThe mean age at diagnosis was 67.6 years, and 85.7% of patients were male. Patients received a median of 3 (range=2-6) neoadjuvant therapy cycles (77% with carboplatin and paclitaxel). Postoperative pathology revealed mediastinal lymph node involvement in 37.1% and angiolymphatic invasion in 25.7% of patients. Adjuvant treatment was administered to 51.4% of patients, with no factor significantly associated with this decision. During a median follow-up of 40.6 months, the recurrence rate was 37.1%, and the mortality rate was 40%. The median EFS was 25.4 months, while the median OS was not reached. Two-year EFS and OS rates were 53.9% and 66.3%, respectively. Univariate analysis identified mediastinal lymph node involvement, angiolymphatic invasion, and receiving ≥3 neoadjuvant cycles as significant predictors of shorter EFS, while only mediastinal lymph node involvement significantly affected OS. Multivariate analysis did not reveal independent predictors, likely due to collinearity.
conclusionComplete resection after neoadjuvant therapy yields favorable long-term survival in selected patients with initially unresectable NSCLC. Postoperative mediastinal lymph node status remains a critical prognostic factor.
