本文对成都市七区二县1990─1996年居民中消化道恶性肿瘤死亡15731例进行了分析，七年中消化道恶性肿瘤平均死亡率为48．45／10万，标化死亡率为46.06／10万，死亡率有缓慢上升趋势。15731例消化道恶性肿瘤死亡总数中肝癌（死亡率为15．44／10万，标化死亡率为14.65／1O万）死亡5013例占总死亡数的31．87％，居首位；依次为胃癌（死亡率为14．95／10万，标化死亡率为14．22／10万）死亡4855例占总死亡数的30．86％；食管癌（死亡率为11．05／10万，标化死亡率10．51／10万）死亡3587例占总死亡数的22．80％；肠癌（死亡率为7．01／10万，标化死亡率为6．68／10万）死亡2276例占总死亡数的14．47％。男性消化道恶性肿瘤平均死亡率为66．46／10，女性平均死亡率为29．29／10万；男女性死亡比值为2．26：1，男性消化道恶性肿瘤死亡率高于女性。城区消化道恶性肿瘤死亡率高于郊县，死亡率随年龄增长而上升，特别是45岁以上死亡率上升幅度较大。消化道恶性肿瘤严重威胁中老年人群健康。
This article analyzes 15,731 cases of gastrointestinal cancer deaths among residents in seven districts and two counties in Chengdu from 1990 to 1996. The average mortality rate of malignant tumors in the digestive tract during the seven years was 48.45 per 100,000, and the standardized mortality rate was 46.06/ With 100,000, the death rate has been slowly rising. Among the 15731 cases of malignant digestive tract cancer deaths, liver cancer (15.44/100,000 death rate, standardized death rate of 14.65/100 000), 5013 cases accounted for 31.87% of the total deaths, ranking first; followed by Gastric cancer (death rate 14.95 per 100,000, standardized death rate 14.22 per 100,000) 4,855 cases of deaths 30.86% of total deaths; esophageal cancer (mortality 11.05 per 100,000 The standardized mortality rate was 10.51 per 100,000. 3587 deaths accounted for 22.80% of the total deaths. Intestinal cancer (mortality was 7.01 per 100,000, standardized mortality was 6.68 per 100,000). 2276 cases accounted for 14.47% of the total deaths. The average mortality rate of male gastrointestinal cancer was 66.46/10, and the average mortality rate of females was 29.29/10 million; the ratio of male to female mortality was 2.26:1. The mortality rate of male gastrointestinal cancer was higher than that of females. The mortality rate of malignant tumors in the digestive tract of the urban area is higher than that in the suburbs. The mortality rate increases with age, especially the mortality rate above the age of 45 increases significantly. Malignant tumors of the digestive tract seriously threaten the health of middle-aged and elderly people.
