Prognostic evaluation of dirty necrosis and tumor necrosis in gastric cancers.
Article in Scientific reports, 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
This study examines the prognostic significance of tumor necrosis and dirty necrosis in gastric cancer. Tumor necrosis, often linked to rapid tumor growth and insufficient vascularization, is a known poor prognostic indicator in several cancer types. Dirty necrosis, a special form seen with neutrophils and necrotic debris, has prognostic value in cancers like colorectal carcinoma and renal cell carcinoma. The presence of tumor-associated neutrophils (TANs) and NETosis, a process where neutrophils release extracellular traps, also plays a role in tumor progression and prognosis. This study included 187 gastric cancer patients who underwent surgery at Eskisehir Osmangazi University. Dirty necrosis was present in 39.6% of cases, with significant associations found between dirty necrosis and tumor type, grade, lymph node stage, and TIL presence. The study demonstrated that dirty necrosis correlated with longer recurrence-free survival and overall survival. Additionally, patients with dirty necrosis and prominent TILs exhibited improved survival outcomes. The findings suggest that dirty necrosis, particularly when associated with TIL, may indicate a better prognosis in gastric cancer. This study highlights the importance of re-evaluating necrosis types in gastric cancer prognosis and treatment strategies.
