Tumor necrosis, an independent prognostic factor for predicting gastric gastrointestinal stromal tumors.

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: Tumor necrosis has been identified as an independent adverse prognostic factor in various human malignancies; however, its prognostic value in gastric gastrointestinal stromal tumors (gGISTs) remains uncertain. This study aimed to investigate the association between tumor necrosis and overall survival (OS) in patients with gGIST who underwent radical surgical resection. Methods: In this retrospective cohort study, clinical and pathological data from 1,463 patients with gGIST were analyzed. The association between tumor necrosis and OS was assessed using univariate analysis with log-rank tests and multivariate analysis with Cox proportional hazards regression models. Results: Tumor necrosis was observed in 238 patients (16.3%) and was significantly associated with tumor location (P=0.044), tumor size (P<0.001), mitotic count (P<0.001), and modified National Institutes of Health (NIH) risk categories (P<0.001). Multivariate analysis confirmed tumor necrosis as an independent unfavorable predictor of OS (P=0.02). Incorporating tumor necrosis into the modified NIH risk classification enabled the stratification of patients into five prognostically distinct groups (P<0.001). Conclusions: Tumor necrosis was identified as an independent adverse prognostic factor in gGIST, and its integration into the modified NIH classification improves prognostic accuracy, supporting a refined risk stratification system for enhanced clinical decision-making and patient management.
