The role of restaging borderline ovarian tumors: Single institution experience and review of the literature
Introduction
Borderline ovarian tumors (BOTs) were first described by Taylor in 1929 [1] and were introduced in 1971 by FIGO [2] as a category of epithelial ovarian tumors. They account for 10–15% of all ovarian epithelial tumors, primarily diagnosed in young women [3], [4], [5]. Approximately 70% of these tumors are stage I at the time of diagnosis with a 5-year survival rate of 95–97% [6]. Malignant transformation occurs in less than 0.5%, although extra-ovarian lesions, such as invasive implants, are more frequent (up to 35% in some series [7]). Therefore, both prognosis and adjuvant treatment of these tumors depend on the presence of the implants. Since early stage is the most important prognostic factor, restaging procedure could be justified. However, according to the data from the literature the issue is still controversial [8].
The aim of this study is to evaluate the role of restaging in the management of borderline ovarian tumors by analysing data on patients referred to our center after being diagnosed in other institutions, and by reviewing the available literature.

Materials and methods
Further to the approval of the Institutional Review Board, we retrospectively reviewed the clinical records of patients with borderline ovarian tumors referred to our centre further to diagnostic surgery in other hospitals to be submitted to restaging. From December 1995 to May 2008, 186 patients were treated at our institution for BOT.
The data collected included patients' age, primary surgery, restaging surgery, FIGO stage at first and second procedure, pathological findings, and follow-up
Results
Among the 186 records reviewed, 70 met the inclusion criteria described above. The median age was 43 years (range 14 to 71 years). The different procedures carried out as primary surgery and restaging surgery are listed in Table 1. After primary surgery, only 5 patients (7%) had abnormal CA125 values and three (43%) of them were eventually upstaged.
The median time from the first surgery to the restaging procedure was 132 days (range 15 to 330 days). The median length of stay was 2.7 days (range 1 to
Discussion
The role of surgical restaging for borderline ovarian tumors is still controversial. Guidelines on BOTs surgical staging are the same as those of invasive ovarian tumors [11]. The role of retroperitoneal restaging remains unclear for borderline ovarian tumors and it does not seem to be as crucial as for the malignant counterparts [12], since in the latter it may have both prognostic and therapeutic implications. The results of a study conducted by Seidman and Kurman [13] suggested that

2021, European Journal of Obstetrics and Gynecology and Reproductive BiologyCitation Excerpt :In the present study, BOTs were commonly reclassified due to the frequent occurrence of intra- or pre-operative rupture (n = 7, 50 % of cases), but remained FIGO stage I. Only one case was upstaged to FIGO stage IIB; this was a micropapillary serous BOT with a micro-invasive implant (Case 13). Therefore, few cases in this study required upstaging, which is consistent with the literature [15,30]. In addition to the micropapillary component, other prognostic factors have been identified recently in the risk of recurrence for FIGO stage I serous BOTs (i.e. most BOTs detected during pregnancy), such as young age (<30 years), conservative treatment by cystectomy, and bilateral character [31].
