A retrospective study of 32 borderline ovarian tumours: The experience of a non-specialized centre

Background: We evaluated the clinical features and treatment of patients with borderline ovarian tumors.

Methods: This was a retrospective review of the charts of 32 patients with borderline ovarian tumours that underwent surgery at the Department of Obstetrics and Gynaecology, Tzaneio General Hospital of Piraeus, over a 14-year period (1/1990-12/2003).

Results: Of the patients 62.5% were pre- or peri-menopausal. Mean age was 41.6 years. Five patients (15.63%) had undergone pelvic surgery (caesarean section not included) for unrelated reasons prior to the diagnosis of borderline tumour. Mean follow-up was 71.37 months and all patients showed up for their scheduled appointment during the first trimester of 2004. Pain was the presenting symptom in 37.5% (12/32) of patients. Twenty patients were diagnosed either by ultrasound (12.5%, 4/32) or during unrelated surgeries (50%, 16/32) and reported no relevant symptoms at the time of diagnosis. Treatment was conservative, comprised of either cystectomy (3/32), unilateral salpingo-oophorectomy (13/32), and unilateral salpingo-oophorectomy with myomectomy (1/32). Abdominal hysterectomy with bilateral salpingo-oophorectomy was performed in 15 patients for unrelated conditions (uterine pathology). Mucinous borderline tumours were identified in 11 patients (34.38%), serous borderline tumours in 17 patients (53.12%), and nonserous-mucinous borderline tumours in four patients (12.5%). Omentectomy was performed in two cases, biopsy of the controlateral ovary was performed in five cases and peritoneal washing in eight cases. Restaging surgery was performed at the Metaxa Anticancer Piraeus Hospital in 11 patients (34.38%). One patient who did not undergo a restaging operation had a recurrence of the disease.

Conclusion: Suboptimal staging remains a major problem during the initial operation in non-specialized centres in gynaecologic malignancies.
