Neuroendocrine tumors of the gynecological tract: A narrative literature review.

Neuroendocrine neoplasms (NENs) of the gynecological tract are a rare, heterogenous and aggressive group of neoplasms, with high recurrence rates and poor prognosis. In this review we focus on NENs of the gynecological system emphasizing the classification, epidemiological and clinical characteristics of NENs across the gynecological tract (cervix, endometrium, ovary, vagina, and vulva), risk/prognostic factors, pathology and molecular biology (including actionable genomic mutations), imaging, staging and the most effective treatment modalities in the "standard of care" approach as well as the pipeline products. We also focused on metastatic spreading patterns of gynecological NENs.
