Advanced stage mucinous adenocarcinoma of the ovary is both rare and highly lethal

Primary mucinous adenocarcinomas of the ovary are uncommon, and their biological behavior is uncertain. Retrospective studies have suggested that many mucinous carcinomas initially diagnosed as primary to the ovary have in fact metastasized from another site. A prospective randomized trial provided an opportunity to estimate the frequency of mucinous tumors, diagnostic reproducibility, and clinical outcomes.
