Objectives. To evaluate the fertility and recurrence outcomes in women treated with fertility-sparing surgery for borderline ovarian tumors. Methods. A total of 142 patients with borderline ovarian tumors managed surgically from 1993 to 2004 were identified from gynecologic oncology and pathology files of SSK Ankara Maternity and Women’ s Health Teaching Hospital. Sixty-two of those patients who had conservative surgery were eligible for the study. Information was acquired by retrospective medical record review and patient interview. Results. The observed recurrence rates after radical and fertility-sparing surgery were 0.0% and 6.5% , respectively. Four patients from the conservative surgery group developed recurrence, in contrast to none of the patients from the non-conservative surgery group. No disease-related deaths occurred in any group. In the conservatively managed group, ten women had successful pregnancies, with a total of 10 live births and 3 abortions. The mean duration of follow-up for the conservative surgery group was 44.3 months (range, 3- 128). Conclusion. Fertility-sparing surgery for borderline ovarian tumors should be considered for women in the reproductive age group who desire preservation of fertility. Recurrence is noted significantly more often after this type of treatment and close follow-up is needed to detect recurrent disease. Objectives.
