Impacts of Upper Gastrointestinal Surgery Volume on Gastric Cancer Outcomes

High overall volume of upper gastrointestinal surgeries at hospitals, despite lower gastrectomy volume for cancer, leads to similar postoperative outcomes to high gastrectomy volume centers. Equivalence in 5-year survival rates between hospitals with mixed and high gastrectomy operation volumes across all disease stages. Findings suggest high-volume upper gastrointestinal surgery centers provide comparable outcomes and enhance accessibility to quality cancer care.
