Staging Classification Comparison of Resected Pancreatic Neuroendocrine Tumors (pNETs) Utilizing the National Cancer Database (NCDB) Abstract #1908

Introduction: The staging classification of pNETs remains a matter of debate and no obvious superior system has emerged.
Aim(s): To compare 3 current pNET staging classifications using NCDB data from 2004-2014 in patients (pts) who have undergone resection.
Materials and methods: Pts with pathologically confirmed pNET, complete data allowing restaging by AJCC (7th ed), ENETS, and mENETS classifications, who had resection of the primary tumor were included (N=4072). Overall survival (OS) was analyzed utilizing Kaplan-Meier curves, log-rank tests were used to compare stage systems. Cox proportional hazards methods were used to control for age, sex, grade, tumor location, functional status, stage, and year of diagnosis.

#74 Non-functioning pancreatic endocrine tumors: diagnostic criteria and surgical treatment
Introduction: Neuroendocrine tumors were considered rare tumors several years ago. Several reports published recently have observed increased incidence of NETs suggesting that NETs are more prevalent than previously reported. Non-functioning pancreatic endocrine tumors (NFPETs), better defined as non-hyperfunctioning, are characterized by the absence of clinical or biochemical evidence of hormone hypersecretion. From the clinical standpoint, NFPETs can be either occasionally encountered or manifest clinically similar pancreatic tumors. Since both NFPET treatment and prognosis significantly differ from that of ductal adenocarcinoma and other pancreatic malignant tumors, an accurate differential diagnosis is needed.

#232 Prognostic Factors and Survival in 481 Patients with Pancreatic and Peripancreatic Endocrine Tumors: Results from the National Cancer Registry of Spain (RGETNE)
Introduction: Duodenopancreatic neuroendocrine tumors (NETs) are uncommon neoplasms with a wide spectrum of clinical presentation. The infrequent occurrence of these tumors makes large experiences very scarce.

#338 Pancreatic Endocrine Tumors: TNM staging and WHO Grading Relation with Prognosis
Introduction: Pancreatic endocrine tumors (PETs) are heterogeneous, rare neoplasms (large experience is unlikely). Prognostic stratification based on TNM staging and WHO grading is still under debate.
