上1/3胃癌较其它部位的胃癌发生率有所上升,这些病人的预后差,切除术后5年存活率为4～32%。本文描述了上1/3胃癌的临床病理特征及影响预后的因素,并与其它部位的胃癌作了比较。1965年～1985年,对1,468例原发性胃癌行胃切除,其中356例(占24.3%)为上1/3胃癌。若肿块1/2以上的部分位于胃上1/3,则视为上1/3胃癌。病理诊断及分型依据日本胃癌学会的外科和病理标准。作者对356例上1/3胃癌患者与1,112例其它部
The incidence of gastric cancer in the upper 1/3 gastric cancer is higher than that in other sites. The prognosis of these patients is poor, and the 5-year survival rate after resection is 4 to 32%. This article describes the clinicopathological features and prognostic factors of the upper 1/3 gastric cancer and compares it with other sites of gastric cancer. From 1965 to 1985, gastrectomy was performed on 1,468 primary gastric cancers, of which 356 (24.3%) had upper 1/3 gastric cancer. If the 1/2 or more of the mass is located on the upper 1/3 of the stomach, it is regarded as the upper 1/3 of the stomach. Pathological diagnosis and classification are based on the surgical and pathological criteria of the Japanese Gastric Society. The author of 356 patients with upper 1/3 gastric cancer and 1,112 patients with other departments
