Clinical analysis of patients with recurrences of borderline ovarian tumors including surgical treatment

OBJECTIVES: Risk of recurrences of borderline ovarian tumors is low (7-10%) but the cases with incidence of recurrence have worse prognosis. The time between primary operation and the first diagnosis of recurrence and treatment is different. DESIGN: The purpose of the current study was to evaluate frequency and the methods of treatment patients with recurrences of borderline ovarian tumors. MATERIALS AND METHODS: The analyzing group consists of 129 patients with borderline tumors of the ovary (BTO) diagnosed and treated in Department of Gynecology between years 1978-2000. RESULTS: In our recurrences developed in 7% of patients. The recurrences in BTO were connected with stage of BTO, types of primary operations and residual disease. Recurrences developed in 5,9% patients with stage I and in 18,1% patients with stage II/III. Similarly recurrences developed in 5,8% patients with no residual disease and in 20% patient with residual disease. A higher relapse rate was observed in patients treated conservatively but recurrences was quickly recognized and efficaciously treated. 5 years survival of patients without recurrences was 91,7% and with recurrences was 72,9%. CONCLUSIONS: 1. Risk of recurrences of BTO is low (7%) and depends on stage and residual disease. 2. Risk of recurrences is higher after primary conservative operation but long follow-up and regular gynecological examinations allows to early diagnosis and treatment of recurrences. 3. Prognosis of patients with recurrences of BTO is good. 5-years survival was 90,6% of group without and 72,9% of group with recurrences of BTO.
