Perioperative Chemoimmunotherapy for Resectable Gastric and Gastroesophageal Junction Cancer: A Conceptual, Biomarker-Informed, and Regionally Adapted Framework.
Review in Journal of gastrointestinal cancer, 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
Perioperative treatment for resectable gastric and gastroesophageal junction (GEJ) adenocarcinoma is changing rapidly as immune checkpoint inhibition enters a field historically shaped by distinct chemotherapy and surgical paradigms. This review critically appraises contemporary perioperative and adjuvant evidence and proposes a biomarker-informed, regionally adaptable framework for clinical decision-making. We conducted a structured narrative review of perioperative and adjuvant systemic therapy, surgical outcomes, treatment completion, safety, and biomarker evidence in resectable gastric and GEJ adenocarcinoma, with emphasis on randomized phase III trials, mature follow-up, prospective biomarker studies, and relevant regulatory data. MATTERHORN demonstrated significant event-free survival and subsequently overall survival benefits with perioperative durvalumab plus fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT), supporting regulatory approvals. In contrast, KEYNOTE-585 increased pathological complete response but did not meet the prespecified event-free survival statistical boundary, while ATTRACTION-5 did not establish postoperative nivolumab after D2 gastrectomy as a new standard. MSI-H/dMMR is the most clinically relevant perioperative biomarker, although chemotherapy-free strategies remain investigational. PD-L1 thresholds validated in advanced disease should not be directly transferred to the curative setting. Pathological response, ypN status, circulating tumor DNA/molecular residual disease, and emerging multimodal risk models are prognostic, but none currently provides validated treatment-effect prediction sufficient to mandate postoperative escalation or de-escalation. Perioperative treatment should integrate resectability, surgical quality, patient fitness, regional chemotherapy backbones, MSI-H/dMMR status, treatment completion, and postoperative recovery. The proposed framework is conceptual rather than a guideline and requires prospective validation.
