Ovarian-sparing local mass excision for ovarian fibroma/fibrothecoma in premenopausal women

Objectives To evaluate the recurrence rate of ovarian fibroma/fibrothecoma and reproductive outcomes following ovarian-sparing local mass excision in premenopausal women. Study design A retrospective cohort study was performed at two gynecologic surgery centers using data collected between January 2005 and December 2011. It included premenopausal patients treated with ovarian-sparing local mass excision and pathologically proven ovarian fibroma/fibrothecoma who were followed up for at least 6 months. The recurrence of fibroma/fibrothecoma and pregnancy outcomes in those who wanted to conceive after local mass excision were collected and analyzed. Results The mean age of the patients (n = 50) was 33.3 ± 6.9 years (range, 20–50 years), and the mean follow-up duration was 26.6 ± 19.2 months (range, 6–88 months). Fibroma was present in 40 patients, fibrothecoma in 7, and cellular fibroma in 3. Natural conception occurred in 11 of the 12 patients who became pregnant during the follow-up period. On follow-up ultrasonography, one patient experienced recurrent disease, 50 months after initial surgery, resulting in a crude overall recurrence rate of only 2%. Conclusion Given the 2% recurrence rate of ovarian fibroma/fibrothecoma following ovarian sparing local mass excision, local mass excision appears to be an effective surgical option in women of reproductive age.
