A Study on Multiple Primary Gastric Carcinoma

Abstract

Over the last 18 years, patients with multiple gastric carcinoma were studied by using Moertel's principle. Of a total of 692 patients with gastric carcinoma, there were 24 (3.4%) with multiple gastric carcinoma, including 22 synchronous double lesions and 2 synchronous triple lesions. Seven patients had both primary and secondary lesions in the M-area. Secondary lesions were found to be in the early stages of cancer development. Only one case showed protrusion coupled with indentation. Histologically, 14 patients (58.3%) had double differentiated lesions.In 6 cases, secondary lesions in the C-area showed little histological differentiation. When we perform distal gastrectomy, it is important to refer to the C-area in detail before and during the operation.
