Clinicopathological features, survival and prognosis were followed up. Rates were compared using chi-square test, means between multiple groups were compared using ANOVA, OS was analyzed by Kaplan–Meier, COX proportional hazard model was for analyzing the prognosis. Number of cases showed increasing trend since 2000. Female exceeded Male except for jejunum tumor, but without significant difference; There were no significant difference between cases of more and less than 60 years of age.
