Abstract:
Gastric stump cancer(GSC) is defined as newly developed remnant stomach cancer following gastrectomy. This definition initially referred to carcinoma detected in the remnant stomach more than 5 years after the primary surgery for a benign disease. Subsequently, this timeframe was extended to 10 years after the primary surgery for a malignant disease. Recently, the concept of "carcinoma in the remnant stomach(CRS)" proposed by the Japanese Gastric Cancer Association was introduced in China. The new definition encompasses all carcinomas arising in the remnant stomach following gastrectomy, irrespective of the histology of the primary lesion, extent of resection, or reconstruction method. It includes all carcinoma types that have developed in the remnant stomach, such as newly developed cancer, recurrent cancer, remaining cancer, and multiple cancers. Considering the current diagnosis and treatment status of gastric cancer in China, if CRS is to be used as a direct equivalent to GSC in clinical practice, confusion may arise concerning disease identification and diagnosis. Following several discussion rounds, a meta-analysis of the literatures at home and abroad, and a multicenter national retrospective study with a large sample population, the "Chinese surgeons' consensus opinion for the definition of gastric stump cancer (version 2018)" was completed. By reviewing the detailed evidence-based medicine supporting the consensus document, this paper aims to assist clinical diagnosis and enhance future academic exchange.
