Prognostic impact of mitosis and necrosis in non-mucinous lung adenocarcinomas and correlation with IASLC grading system.
Article in Histology and histopathology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIn 2020, the International Lung Cancer Study Group (IASLC) Pathology Committee established a grading system for non-mucinous primary lung adenocarcinomas. This grading system is based on whether areas of high-grade patterns are present in more than 20% of the tumor. Parameters, such as necrosis, mitotic activity, lymphovascular invasion (LVI) and spread through air spaces (STAS), are excluded from evaluating the grading system.
methodsA total of 217 patients' lung resection materials for primary lung adenocarcinoma were re-reviewed using the IASLC grading system. Necrosis, mitotic activity, LVI status and STAS were also evaluated in the resection materials, aiming to demonstrate the relationship between these histopathological features and clinical outcome data.
resultsAt all stages, overall survival (OS) and recurrence-free survival (RFS) were related to grade (
conclusionsThe new grading system provides a highly efficient prognostic classification for survival. Necrosis and high mitotic count are important prognostic parameters for survival. Additionally, necrosis is a stage-independent prognostic factor for OS in grade 3 tumors, although no effect on prognosis can be demonstrated in grade 2 tumors.
