Impact of STAS on Lung Resections for Adenocarcinoma: A Retrospective Analysis.
Article in Cancers, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundTumor spread through air spaces (STAS) has been proposed as a histopathological marker of aggressive tumor biology in adenocarcinoma of the lung (ADCL). Its independent prognostic significance and clinical implications regarding surgical strategy remain controversial. This study evaluated clinicopathological correlates and the prognostic impact of STAS in a homogeneous cohort of resected ADCL.
methodsWe retrospectively analyzed 100 patients with primary ADCL resected between 2009 and 2018. STAS was classified as absent, low (1-4 clusters), or high (≥5) by an experienced pathologist. Associations between STAS and clinical, surgical, and pathological variables were tested with univariate analyses and multivariable logistic regression. Overall survival (OS) was evaluated using Kaplan-Meier and Cox regression.
resultsSTAS was present in 46% of tumors and was significantly associated with a higher pathological N category (pN0-pN3;
conclusionsSTAS is frequent in resected ADCL and correlates with adverse pathological features and reduced OS in univariate models. In multivariate analysis, STAS did not emerge as an independent prognostic factor. These findings support the interpretation of STAS as a marker of aggressive tumor biology rather than an independent determinant of prognosis or surgical decision-making.
