Risk Factors for Survival from Neuroendocrine Neoplasia with Unknown Primary Tumor Site

#1237

Introduction: Neuroendocrine neoplasia (NEN) with unknown primary site (NEN-CUP) may have a poor prognosis. We evaluated the clinical presentation, therapy, outcome, and risk factors for adverse outcomes in patients with NEN-CUP.

Aim(s): Role of surgery in NEN-CUP

Materials and methods: In 243 patients who had NEN, a retrospective review was performed in 38 patients who had NEN-CUP tumors. The 38 patients who had NEN-CUP were evaluated in 3 groups: group 1 (surgery; primary tumor detected; n=10); group 2 (surgery; no primary tumor detected; n=10); and group 3 (no surgery; n=18). Risk factors were evaluated with univariate and multivariate analysis.
