Introduction: Neuroendocrine tumors (NETs) metastatic to the ovary are traditionally considered rare, but data are lacking. This study seeks to better characterize the prevalence and outcomes of patients with neuroendocrine ovarian metastases (NOM). Methods: Women with well-differentiated lung and gastroenteropancreatic NETs 2007-2017 were identified by medical record query. Clinicopathologic data were reviewed among patients with and without NOM. Results: Of 242 patients, 27 (11.2%) developed NOM. NOM developed in 24.8% of SBNET patients and 65.7% of patients with carcinomatosis and intact ovaries. 33.3% had associated small bowel obstructions; 11.1% had ureteral obstruction. NOM were not apparent on imaging in 29.6% nor visible intraoperatively in 8.3%. Five-year survival rate was 61.5%. Those who underwent oophorectomy had a lower rate of subsequent ureteral obstruction (p < 0.01). Conclusions: NOM are more prevalent than previously reported and associated with significant morbidity. Empiric oophorectomy may be considered for SBNET patients and strongly advised in carcinomatosis. (C) 2020 Published by Elsevier Inc.
