Analysis of histological parameters of aggressiveness in resected lung squamous cell carcinoma.
Article in Pathologica, 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
Introduction: Lung squamous cell carcinoma (LUSCC) lacks consistent morphological criteria for tumour grading. Tumour budding (TB), defined as isolated cells or clusters of fewer than 4 cells at the invasive front, is prognostic in several carcinomas but remains insufficiently validated in LUSCC. Objective: To assess histopathological features of aggressiveness (including TB) in resected LUSCC as prognostic parameters and grading factors. Methods: We retrospectively analysed 296 LUSCC cases (2010-2021, University of Turin). Clinical data were collected and slides were reviewed for subtype, nuclear features, mitotic count, infiltration pattern, TB, spread through air spaces (STAS), desmoplasia, pleural/vascular/perineural invasion, and tumour-infiltrating lymphocytes. Associations with recurrence-free and overall survival were tested. Results: High TB (≥ 5 buds) correlated with pleural invasion and advanced T stage and was significantly associated with shorter recurrence-free (HR 1.84, p = 0.008) and overall survival (HR 1.73, p = 0.003), independently of stage. Nuclear enlargement and necrosis also predicted worse outcomes, while surgery had an overall protective impact. Conclusion: TB, necrosis, and nuclear size are independent predictors of outcome in LUSCC. Their inclusion in pathology reports may improve grading, refine prognosis, and guide management.
