作者报道日本九洲大学医学院自1965至1985年20年间对1150例进展型胃癌(病变侵犯超过粘膜下层)行胃切除的研究。在1150例中,1141例(99.2%)随访5年以上,并分成两组:(1)第一组为1965～1974年共622例;(2)第二组为1975～1985年共519例。按照 Sugana组织学分类可分为分化和未分化型;按照日本胃癌研究会制定的标准分成1～5型。存活率按生命表方法进行计算。结果:第一组和第二组病人的年龄、性别、肿瘤部位、大小、大体和组织学分型均具有显著性差异。在第二组中,70岁以上女性,位于胃上2/3部,大于10 cm的肿瘤,肉眼观察4～5型,以及末分化型较为多见;而小于70岁、男性胃下1/3部,直径6～10cm 的肿瘤,大
The authors reported on the gastrectomy of 1150 cases of progressive gastric cancer (lesions invaded beyond the submucosa) during the 20 years from 1965 to 1985 in Japan’s Jiuzhou University School of Medicine. Among 1150 cases, 1141 cases (99.2%) were followed up for more than 5 years and divided into two groups: (1) The first group consisted of 622 cases from 1965 to 1974; (2) The second group consisted of 519 cases from 1975 to 1985. . According to Sugana histological classification can be divided into differentiated and undifferentiated type; in accordance with the standards established by the Japanese Gastric Cancer Research Association is divided into 1 to 5 type. The survival rate is calculated according to the life table method. Results: There was a significant difference in the age, sex, tumor location, size, gross and histological types of the first and second groups of patients. In the second group, women over the age of 70 were located in 2/3 of the stomach, tumors larger than 10 cm, macroscopically observed 4 to 5, and terminally differentiated types were more common; and less than 70 years of age, men under the stomach 1/ Three tumors of 6 to 10 cm in diameter, large
