The Importance of Appendectomy in Surgery for Mucinous Adenocarcinoma of the Ovary.

Objective: The aim of this study was to assess the importance of appendectomy during surgery for mucinous ovarian cancer. It can be difficult to distinguish between primary ovarian and primary appendiceal cancers clinically, histologically, and immunohistochemically. Removal of the appendix may facilitate differential diagnosis, improve staging, and possibly increase 5-year survival but may also be associated with increased postsurgical morbidity.
