Abstract: Objective To explore the effects of different age，occupation and operative methodon survival rate in patients with radical gastrectomy in Yangjiang district ，a city locates in the west of Guangdong. Methods One hundred and sixty eighty patients with radical gastrectomy were performed five-year follow-up as research object. and analyzed. The survival condition in different risk factors was analyzed Using Kaplan Meier method. Results A total of 101 cases of patients died，survival interval ranged from 2 months to 70 month，and 5 years survival rate was 34.6% . Kaplan and Meier analysis showed there were no statistical differences in gender on survival time（P>0.05）. Survival time in young and middle- aged patients was shorter than old and middle- aged patients （P<0.05）. Survival time in mental labor patients was shorter than in manual labor patients（P<0.05）. Survival time in laparoscopic gastrectomy patients was longer than in open gastrectomy patients （P<0.05）. Conclusion The Results above showed agedness，laparotomy，and mental work were risk factors for the post- operation patients with gastric cancer in Yangjiang City.

摘要： 目的 探讨我省阳江市不同龄段、职业及手术方式对胃癌根治术后患者生存率的影响。方法 以我院肿瘤科行根治性切除手术并随访5年的168例该市籍胃癌患者作为观察对象，观察患者总体生存时间，使用Kaplan-Meier法分析不同因素下胃癌根治术后患者的生存情况。结果 观察期内共有101例死亡，患者的生存区间为2～70+月（删失），5年总体生存率为34.6%；Kaplan-Meier分析显示：男女胃癌根治术后患者生存时间比较无统计学意义（P>0.05），中青年胃癌根治术后患者生存期长于于中老年（P<0.05），脑力劳动患者的生存期短于体力劳动者（P<0.05），腹腔镜胃癌根治术患者生存期长于开腹胃癌根治术患者（P<0.05）。结论 年龄、施行开腹手术、从事脑力劳动，是影响该市胃癌根治术后患者生存预后的3个危险因素。
