Abstract

BACKGROUND:

The aim of this study was to evaluate prognostic factors for recurrence after conservative treatment of a large series of 'apparent' stage I serous borderline ovarian tumors (SBOTs).

PATIENTS AND METHODS:

A review of 119 patients treated conservatively between 2000 and 2009 with follow-up data. All pathological slides were reviewed by the same expert pathologist. Prognostic factors for recurrence were studied (age, histological subtypes and surgical procedure).

RESULTS:

Conservative surgical procedures were: unilateral cystectomy (n = 43, 36%); unilateral adnexectomy (UA; n = 50, 42%); bilateral cystectomies (n = 11, 9%) and UA + contralateral cystectomy (n = 15, 13%). Stromal microinvasion and/or a micropapillary pattern was present in 21 (18%) and 13 (11%) patients, respectively. With a median follow-up of 45 months, 38 (32%) patients relapsed (10 also had peritoneal disease in the form of noninvasive implants at the first recurrence). In 2 of these 38 patients, progression-to-invasive disease occurred at the second and third relapse (one patient died to the recurrence). Three prognostic factors for recurrence were identified in the univariate analysis: a young age (< or >30 years old), the type of conservative treatment (adnexectomy versus cystectomy) and tumor bilaterality. In the multivariate analysis, only age remained statistically significant.

CONCLUSION:

In this series (the largest reported, to date, on recurrences after the conservative management of stage I SBOT), the risk of relapse was not related to tumor histological subtypes (micropapillary and stromal microinvasion) nor to the use of complete staging surgery. Invasive recurrences were very rare in stage I SBOT, but did occur. A young age, tumor bilaterality and the use of a cystectomy were identified as risk factors for recurrence, suggesting that management of fertility preservation (particularly in very young patients) should be associated with a meticulously conducted follow-up.
