Methods The follow-up data of 50 patients with pancreatic cancer between 1996 and 2006 were analyzed. SPSS 13.0 was performed to analyze the follow-up data. Results For 50 followed-up patients, 1, 3, 5 years cumulative survival rate is 63.0 %, 24.0%，12.0%, respectively. Operative mortality is 4% and 38.0% of patients have complication after operation. Cox regress indicates that surgery modus and staging are significantly risk factor for cumulative survival rate (p<0.05). Median of survival time and 3,5 years cumulative survival rate of patients performed by R0 resection are 30 months, 41.0%, 20.0%, respectively, which higher than R1 and R2 (p<0.05). Three, five-year cumulative survival rate of patients with stageⅠis 49.0% and 28.0%. Conclusion R0 resection is the only effective method to improve the rate of cumulative survival time.
