title: [Comparison of two groups of patients with serous and mucinous types of borderline ovarian tumors].
abstract: OBJECTIVE
  The retrospective comparison of two groups of patients with the most common types of borderline ovarian tumors (BTO): serous and mucinous.
  
  
  METHODS
  All patients were treated between 1978 and 2000 at the 2nd Department of Obstetrics and Gynecology Medical University of Gdańsk. The first group consisted of 58 patients with serous BTO. The second group consisted of 48 patients with mucinous BTO. These groups were compared according to such parameters: age at diagnosis, parity, clinical symptoms, localization of tumor, tumor size, type of operation, stage of disease, utilization of adjuvant therapy, presence of recurrence and 5-year survival. Statistical comparisons were made by the chi 2 test. The clinical life table analysis was performed to determine 5-year survival and comparisons were made by means of the Long Rank tests.
  
  
  RESULTS
  The mean age of serous BTO was 53.1 +/- 12.8 and of mucinous BTO 43.3 +/- 17.9 (p = 0.0000). In the first group 15.5% and in the second 43.8% women were nullipara (p = 0.0602). The main symptom of serous BTO was pain--53.5% patients and that of mucinous BTO increasing girth--47.9% patients (p = 0.0456). The mean size of serous BTO was 13.7 +/- 6.9 cm and that of mucinous BTO was 20.3 +/- 9.5 cm (p = 0.004). 43 patients (89.6%) with mucinous and 28 patients (48.3%) with serous BTO were at I A stage and 9 patients (15.5%) with serous and only one (2.1%) with mucinous were at III stage (p = 0.0008). The mucinous BTO--affected were more frequently treated conservatively than serous BTO--ones which were rather treated radically with using adjuvant therapy (p = 0.003). Residual disease was observed mainly in patients with serous BTO. 5-years survival was better in patients with mucinous BTO, 87.7% and 85.2% respectively (p = 0.0001).
  
  
  CONCLUSIONS
  1. The mucinous BTO occurred more frequently than serous BTO in women of the childbearing age. 2. The extraovarian disease was observed more often with serous BTO than the mucinous BTO. 3. The mucinous BTO was usually bigger than serous BTO and mainly affected only one ovary. 4. The mucinous BTO was more frequently treated conservatively than serous BTO which were rather treated radically with use of adjuvant therapy. 5. The recurrence rate was higher and the 5-year survival was worse in patients with serous BTO.
