PG Versus TG for Advanced PGC
November 16, 2025 updated by: National Taiwan University Hospital
Proximal Versus Total Gastrectomy for Advanced Proximal Gastric Cancer: A Retrospective Double-Center Propensity Score-Matched Cohort Study
We conducted a retrospective study on patients with pathological stage II-III PGC who underwent PG or TG from 2013 to 2023.
Propensity score-matching was applied to adjust for tumor size and stage between the PG and TG groups at a 1:1 ratio.
We evaluated the procedural safety, oncological, and functional outcomes.
