Objective To understand the stomach cancer survival state and trends of Fuzhou in order to evaluate the effect of Ⅱ and Ⅲ prevention in the last 10 years.
Methods Seven hundred and twenty-four stomach cancer cases diagnosed in 1992-1999 are investigated, survival rate, mean survival time and median survival time are calculated by life table method and Kaplan-Meier method, survival time are compared by Logrank Test.
Results Survival rate of 1, 3 and 5 years are 0.637 7, 0.355 8 and 0.230 5, mean survival time and median survival time are 918.35 and 558 days.Difference among survival time of different year groups is staistically significant and survial rate of 1, 3, and 5 years are increased with time.There are significant difference of survival time in age groups, survival time of the group of 75 years old is shorter than 35-70 group.
Conclusion Ⅱ and Ⅲ prevention have initial effect, but stomach cancer survival rate is still not high.
