The role of prophylactic bilateral oophorectomy at the time of initial diagnosis of a unilateral ovarian metastasis in cases with colorectal adenocarcinoma.

摘要

BACKGROUND/AIMS: In cases with a macroscopic unilateral ovarian metastasis of colorectal adenocarcinoma, a clear therapeutic policy regarding a prophylactic bilateral oophorectomy is lacking. METHODOLOGY: Four cases of ovarian metastases of colorectal adenocarcinoma are presented. RESULTS: Case 1 is a 63-year-old with ascending colon carcinoma, Dukes' C, and right oophorectomy due to metachronous ovarian metastasis. Case 2 is a 28-year-old with transverse colon carcinoma, Dukes' D, and right oophorectomy due to synchronous ovarian metastasis. Case 3 is a 40-year-old with rectal carcinoma, Dukes' B, and right oophorectomy due to metachronous ovarian metastasis. Case 4 is a 32-year-old with rectal carcinoma, Dukes' D, and bilateral oophorectomy due to synchronous and metachronous ovarian metastases. Later, in cases 1 and 3, in which a unilateral ovary was preserved, ovarian metastases to the preserved ovary were found and caused severe clinical symptoms. However, by that time their general condition did not permit any additional laparotomy. CONCLUSIONS: Without other extensive metastases, if demonstrable diseases are found in a unilateral ovary, a prophylactic bilateral oophorectomy is recommended.
