title: Gastric cancer treated in 1991 in Japan: data analysis of nationwide registry.
abstract: The Japanese Gastric Cancer Association Registration Committee reported the treatment results and causes of death of patients with primary gastric cancer treated in 1991 at the leading hospitals in Japan. Data of 8851 patients with primary gastric cancer were collected from 113 hospitals, and data of 7935 patients with gastric resection were finally analyzed. The lost-to-follow-up rate was 6.9%; the direct death rate was 1.0%. The cumulative 5-year survival rate (5YSR) of all the patients was 68.2%; 89.9% for Stage I, 69.1% for Stage II, 43.5% for Stage III, and 9.9% for Stage IV. Characteristic findings of the analyzed data were (1) high proportion of early-stage cancer, (2) high resection rate, (3) low mortality rate, (4) low incidence of upper-third cancer, (5) poor treatment results in cases with scirrhous cancer, infiltrating growth, and marked lymphatic or venous invasion, and (6) predominance of systematic (D2) and extended lymphadenectomies possibly resulting in reducing local recurrence and improving survivals.
