Prognostic Factors of Long-term Outcome of Non-functional Pancreatic Neuroendocrine Neoplasms Following Surgical Treatment:A Retrospective Study Based on SEER Database
[Purpose] To investigate the prognostic factors of long-term outcome in surgically resectable non-functional pancreatic neuroendocrine tumors(Pan-NENs) based on Surveillance,Epidemiology,and End Results(SEER) database. [Methods] Patients with non-functional Pan-NENs registered in SEER database between 1990 and 2011 were identified,and those undergoing primary resection were included in the study. Cancer-specific survival of patients was analyzed,and the prognostic factors were determined by Cox univariate a...
