Summary
Brief summary (as posted)
We used the SEER database to analyze the data of patients with PDAC. The database includes patients of 18 registries in the USA from 1973-2013All the malignant cases were followed-up annually to determine vital status. The aim of Our study is to make clearly the long-term survival of younger (age \<80 years) and elderly (age ≥80 years) pancreatic cancer patients underwent PD. Sec-ond, find out the risk factors of poor prognosis in elderly patients.
