title: Mucinous borderline ovarian tumors: Analysis of 75 patients from a single center.
abstract: OBJECTIVE
  To analyze the clinicopathologic features, recurrence and survival rates, reproductive history, and treatment of patients with mucinous borderline ovarian tumors (mBOTs).
  
  
  METHODS
  Patients with a diagnosis of mBOT were evaluated retrospectively. Patients with borderline ovarian tumors other than mucinous type and concomitant invasive cancer were excluded.
  
  
  RESULTS
  A total of 75 patients were identified. Median age was 38 years. The most common symptom was pain (42.7%). Median CA-125 level was 23.5 IU/mL (range, 1-809 IU/mL). Median tumor size was 200 mm (range, 40-400 mm), and 6.7% of mBOTs were bilateral. Thirty-six (48%) patients underwent staging surgery. Two patients (5.9%) had nodal involvement. One patient received platinum-based adjuvant chemotherapy. One (1.3%) patient had recurrence. None of the patients died because of the ovarian tumor. A total of 43 patients had conservative surgery.
  
  
  CONCLUSIONS
  Prognosis of mBOTs is excellent, and fertility-sparing surgery should be considered in the reproductive age group. Furthermore, the necessity of staging surgery is controversial.
