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.
