Serous and Mucinous Borderline Ovarian Tumours: Evaluation of Clinical Outcome and Risk Factors for Recurrence

Objective: Borderline Ovarian Tumors (BOTs) have a good prognosis; however, a few BOT patients experience the relapse of disease, either borderline or malignant. The aims of this study were to analyze the risk factors of relapse.Methods: This is a retrospective study of 31 patients with confirmed BOTs treated in the Salah Azaiez Oncologic institute between 2005 and 2015.Results: 31 cases were identified; median age was 43 years. Most of the patients 27 (87%) demonstrated stage IA. 8 patients had laparoscopic surgery and they were all treated conservatively. Between 23 patients, which had laparotomy, only two cases underwent conservative surgery and the remaining patients had radical surgery. Five patients had recurrences (16.13%). The relapse was occurred meanly 62.38 months after the primary surgery. Among the 5 recurrent cases, one cancerous transformation and 4 borderline recurrences were detected. 3 recurrences of 8 Laparoscopic surgery group and 2 recurrent cases of 23 laparotomic surgery groups were observed but the statistic result of the relation between laparoscopic approach and higher recurrence rate was not significant (P=0.093). 3 recurrences of 10 conservative surgery group and 2 recurrent cases of 21 radical surgery groups were observed. However, it did not show significant difference (P=0.175). Mean age of disease-recurrence group was 42.8 years whereas the one of non-recurrent group was 46.5 years (P=0.65), age was not risk factor of disease recurrence.Conclusion: Even if age, conservative treatment and laparoscopic technique does not reach the statistic significance as a risk factors for recurrence, we can have a definite conclusion. It is necessary to perform more randomized controlled trials to confirm such an assumption.
