Background Borderline tumors are malignant epithelial ovarian tumors with a very low incidence.
Thus experience in diagnostics and treatment is still rare. The aim of this study
was to present and analyze data of women with borderline ovarian tumor (BOT) regarding
clinical features, histological characteristics, diagnostics and treatment management.
Methods In this single center retrospective study women with BOT treated at the Departement
of Gynecology and Obstetrics at the Kantonsspital Luzern between 2011 and 2018 were
analyzed according to their clinical and histological reports.
Results A total of 42 women were enrolled. The median age was 58,5 with a range from 26 to
85, of which 31(73,81%) were postmenopausal, and 11 (26,19%) were still menstruating.
Regarding the histological subtypes, 23 women (54,76%) had serous and 15 (35,71%)
had mucinous BOT. Seromucinous histology was found in 3 patients (7,14%) and endometrioid
in 1 woman (2,38%) respectively. All women underwent surgery. In a total of 39 women
(92,86%) a complete surgical staging for BOT was performed. In 29 women (69,05%) staging
was performed by laparoscopy, 13 (30,95%) underwent laparotomy. Only 1 patient (2,38%)
received chemotherapy.
The mean follow up was 52 months (range=16.3-101.4 months). During this period two
patients recurred after 21,7 and 44 months respectively, the second woman died after
53 months because of the BOT.
Conclusion In the present study women were treated according to the international therapy recommendations
and the rate of recurrence was very low.
