Abstract

Ovarian carcinoids are extremely rare (0.1 % of all ovarian neoplasms). We report on 67 patients from a single institution from 1994 to 2015.  Most benign tumors were diagnosed at surgery for pelvic mass. 29 cases were primary and 38 were metastatic. 93% of the primary tumors were unilateral, mostly with teratomas ,struma ovarii ,trabecular, mucinous and insular . Metastatic tumors were bilateral in 72% of which half were from small bowel, (mainly mucinous adenocarcinomas with neuroendocrine differentiation). All cases had neurosecretory granules ( chromogranin, synaptophysin and 67% expressed CDX2, signaling  intestinal origin. Mean age was 48 for the benign cases and 53 for the malignant ones. Carcinoid syndrome was present in 45% of the malignant cases. Surgery was performed in 95% of the cases and adjuvant treatment in 74%. Overall survival was 86% for benign tumors and 50% for malignant ones at 5 years.

In conclusion: ovarian carcinoids have generally a more indolent course than the more common ovarian cancers and have a better survival. Carcinoid syndrome is present mainly in metastatic tumors as well as well as proliferation index (Ki67), and cytologic atypia.
