（目的）分析启东市１９７２年～１９９１年全人群胃癌患者的观察生存率和相对生存率。（方法）观察生存率用Ｋａｐｌａｎ－Ｍｅｒｉｅｒ法对生存率为观察生存率与同期同性别同年龄组人群寿命表中生存概率之比。（结果）对启东市１９７２年～１９９１年胃癌患者７１１２例（男性４５５５例，女性２５５７例）作生存率统计。１９８２年～１９９１年３年至１０年生存率显著高于１９７２年～１９８１年。

[Purpose]To analyze the observed survival rate(OS)and the relative survival rate (RS) was of stomach cancer patients in thegeneral population in 1972 ~1991.[Method]Kaplan-Meier method was used in calculating the OS.The RS was the ratio of OS to the expectedrate calculated by Qidong life table with respect to age,sex and calendar period.[Result]The 3 - to 10-year OS of 7112 stomach cancer patients(male 4555 and ed 2557)in 1982 ~1991 was significantly higher than those in 1972~1981. The 5-year OS and RS of stomach cancer decreasedwith age.The 1-,3-,5-year OS and RS in males were slightly higher than those in females.The 1-,3-5-year OS and RS with stomach cancer weresignificantly higher than thos with liver cancer.The 5-year RS in Qidong was compared with those in other regions where survivaal data was avanlable.[Conclusion ]The survival rate of stomach cancer is related to period.age,sex and area,survival also related to the social condition and the healthservice such as the level of diagnosis and treatment.
