导言在日本,胃癌是最常见的恶性疾病。1978年死于胃癌者达49,564人。日本每10万人口的胃癌调整死亡率从1958年和1959年处于高峰的39.4下降至1975年的29.6。胃癌与全部恶性疾病总数之比也从1951年的48.8%下降至1978年的35.2%。这是由于其他恶性肿瘤,如肺癌、胰腺癌的发病率增加,而胃癌发病率下降所致。另一方面,胃癌发病率肯定高于其死亡率。这种差异由于早期胃癌发现率的增加而逐年变大,早期胃癌的术后五年存活率已达80%
Introduction In Japan, gastric cancer is the most common malignancy. There were 49,564 people who died of gastric cancer in 1978. Japan’s mortality rate for stomach cancer adjustment per 100,000 population dropped from 39.4, which was at its peak in 1958 and 1959, to 29.6 in 1975. The ratio of gastric cancer to the total number of malignant diseases also decreased from 48.8% in 1951 to 35.2% in 1978. This is due to the increase in the incidence of other malignancies, such as lung cancer and pancreatic cancer, and the decrease in the incidence of gastric cancer. On the other hand, the incidence of gastric cancer is definitely higher than its mortality rate. This difference is increasing year by year due to the increase in the detection rate of early gastric cancer. The five-year survival rate of early gastric cancer has reached 80%.
