Safety of simple cystectomy in patients with unilateral mucinous borderline tumors.

OBJECTIVE

To report on ovarian carcinoma development after cystectomy for a borderline mucinous ovarian tumor.

DESIGN

Case report.

SETTING

A French comprehensive cancer center.

PATIENT(S): One patient who developed recurrence in the form of an invasive ovarian carcinoma after simple cystectomy for a borderline mucinous ovarian tumor.

INTERVENTION(S): Simple cystectomy.

MAIN OUTCOME MEASURE(S): Clinical outcome.

RESULT(S): A 22-year-old nulliparous patient underwent laparoscopic cystectomy. Histological examination revealed a borderline mucinous ovarian tumor. No additional treatment was prescribed. Two years later, the patient relapsed with a malignant mucinous ovarian carcinoma. She underwent surgical resection and staging, including hysterectomy, bilateral adnexectomy, omentectomy, and pelvic and para-aortic lymphadenectomy, and platinum-based chemotherapy.

CONCLUSION(S): Recurrence in the form of invasive ovarian carcinoma may occur in the same ovary after cystectomy in cases of borderline mucinous ovarian tumor. An approach combining systematic unilateral salpingo-oophorectomy and strict monitoring is preferable to simple cystectomy. Such treatment enables preservation of reproductive potential and reduces the risk of developing invasive carcinoma.
