Patients with Upper Third of Esophageal Squamous Cell Carcinoma Have Better Tumor Regression After Neoadjuvant Immunochemotherapy.
Article in Annals of surgical oncology, 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
backgroundSeveral high-quality clinical trials have shown promising results compared with neoadjuvant chemotherapy (NCT) or chemoradiotherapy, further supporting the efficacy of neoadjuvant immunochemotherapy (NICT) for locally advanced esophageal cancer (AEC). This study evaluated the efficacy of NICT in different segments of esophageal squamous cell carcinoma (ESCC) and aimed to identify potential prognostic factors.
methodsA retrospective cohort study analyzed 248 patients. Before undergoing radical surgery, the patients received two to four cycles of NICT. The relationship between different segments of ESCC and both clinical and pathologic characteristics were evaluated.
resultsThe patients with tumors in the upper thoracic esophagus had a higher proportion of lower tumor regression grade (TRG) scores. A significantly higher proportion of patients with TRG 0-1 was observed in the upper and middle thoracic tumor groups than in the lower thoracic group (P = 0.001). In esophageal cancer, TRG 2-3 was significantly associated with lower thoracic tumor location (odds ratio [OR], 3.298; P = 0.003), clinical T3 stage (OR, 2.834; P < 0.001), and clinical N2 stage (OR, 2.557; P = 0.045).
conclusionsThe patients with upper-third ESCC appeared to derive greater clinical benefits from NICT than those with tumors located in the lower third of the esophagus in this post hoc analysis. This could potentially serve as a predictor of NICT efficacy.
