Korea Gastric Cancer Association: Nationwide Gastric Cancer Report in Korea

Abstract

In this study, the Korean Gastric Cancer Association collected 12,152 gastric cancer patients (5,380 in 1995, 6,772 in 1999) from 29 hospitals. Twelve clinicopathological factors- sex, age, operation date, tumor location, size, operation method, gross type of early gastric cancer, Borrmann type, depth of invasion, lymph node metastasis, distant metastasis, stage-were summarized in a database file and analyzed. Chronological change has been evaluated between the patients in 1995 and those in 1999. Proportion of early gastric cancer has been increased from 28.6% in 1995 to 32.8% in 1999. The UICC staging was 25.3% (1995), 29.3% (1999) for stage Ia, 12.7%, 13.9% for stage Ib, 15.7%, 14.8% for stage II, 15.2%, 13.2% for stage IIIa, 8.2%, 6.3% for stage IIIb, and 20.1%, 18.1% for stage IV. The operation of each year was subtotal gastrectomy (67.6%, 67.3%), total gastrectomy (26.6%, 24.1%), proximal gastrectomy (0.3%, 3.6%), wedge resection (0.1%, 0.5%), bypass surgery (2.3%, 1.8%), and open biopsy (3.1%, 2.7%). In early gastric cancer, type IIc was the most common (44.5% in 1995, 42.8% in 1999). The incidence of upper one-third cancer was slightly increased in 1999 (12.5%) than 1995 (11.2%), which is reflected in the increased prox-imal gastrectomy in 1999 (207 cases, 3.6%). There was no significant difference between either groups regarding the regional differences.
