Abstract: Objective To investigate the prognostic factors of survival time of the Uygur and Han nationality elderly patients(over 60 years)with pancreatic cancer in Xinjiang.Methods We carried on a retrospective study of 313 aged patients diagnosed with pancreatic cancer in The First Affiliated Hospital of Xinjiang Medical University from January 1st,2003 to May 30th,2015.We used Kpalan-Meier method for calculation of survival,used Log-rank method for those factors which could affect the prognosis of patients,at last we used Cox proportional risk model for those multiple factors which match the role.Results Three hundred and thirteen cases with pancreatic cancer had a median survival of 157 days,and survival rates of half a year,1 and 2 year were 34.8%,18.5%,7.0%.There was a statistic difference between Uygur patients′ and Han patients′ survival time(P＜0.05).Single factor analysis showed the nationality,tumor size,surgery,ZPS(ECOG),Clinical stage(TNM),chemotherapy and radiotherapy,carcino-embryonic antigen(CEA)level and cancer antigen 199(CA199)level before treatment with outcome(P＜0.05).Multiple factor analysis showed that the clinical stage,surgery(P＜0.05)can be regarded as independent prognostic decision factors.Conclusion The clinical staging,surgical treatment could be regarded as independent prognostic factors for the elderly prognosis of pancreatic cancer.Both of the Han and Uygur patients,earlier discovered and more appropriate surgery treatment are the key for the elderly patients with pancreatic cancer.
