Comparative analysis and optimization of tumor regression grade assessment systems in neoadjuvant therapy for esophageal squamous cell carcinoma.
Article in BMC cancer, 2025. 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
objectiveThis study aims to compare and analyze the effectiveness of different tumor regression grade (TRG) assessment systems in evaluating neoadjuvant therapy for esophageal cancer, with the goal of identifying an optimal assessment method to guide clinical practice.
methodsA total of 467 patients with esophageal squamous cell carcinoma who underwent neoadjuvant therapy followed by surgical resection were included in this study. We comprehensively evaluated the effectiveness of five TRG assessment systems-Mandard, CAP, Becker, JSED, and Ryan-in predicting the prognosis of the primary tumor (PT) and lymph nodes (LN). The inter-observer consistency among these systems was also assessed to identify the most effective TRG evaluation method.
resultsThe performance of the TRG assessment systems in predicting LN prognosis was generally superior to that for PT. Specifically, while the Ryan criteria demonstrated the highest inter-observer consistency coefficient (Mean Kappa = 0.848), its predictive efficacy was the lowest (Mean AUC = 0.502). In contrast, the Becker criteria exhibited the highest predictive efficacy (Mean AUC = 0.609) alongside a good consistency coefficient (Mean Kappa = 0.788). Notably, the modified Modified TRG system not only achieved a higher AUC value (0.624) but also showed excellent inter-observer consistency (Kappa = 0.904).
conclusionThe modified Modified TRG system, with a focus on LN evaluation, demonstrates superior prognostic predictive ability and risk stratification effectiveness. These findings may assist clinicians in more accurately assessing patient prognosis and adjusting treatment strategies accordingly, ultimately optimizing patient treatment pathways.
