Materials and Methods: A retrospective analysis of all patients treated for BOTs at Ankara Oncology Education and Research Hospital between 2008 and 2015 was performed. Data were obtained from hospital records and from the patients by phone. Fifteen patients were identified. Results: The mean age at diagnosis was 38.20 ± 7.37 (27-50) years. Sixty percent of the patients in this study were under 40 years of age. At the time of diagnosis, 93.4% of the patients had Stage I disease and 6,6% of the patients had advanced-stage disease. All patients underwent surgery. Serous histology was found in 73.3% of the patients. Forty-six percent of patients underwent fertility-sparing surgery (FSS) and 53.3% radical surgery. Conclusion: BOTs have perfect prognosis, and FSS may be applied to patients at reproductive ages desiring to protect their fertility.
