title: [Comparison of epidemiological factors between serous and mucinous borderline ovarian tumors: therapeutic implications].
abstract: The goals of this multicenter French retrospective study were to compare epidemiological factors within borderline ovarian tumors (BOT) according to their serous (SBOT) or mucinous (MBOT) type and according to the presence of pejorative histological criteria. We analysed 224 SBOT and 164 MBOT diagnosed between 1990 and 2009. The patients mean age was not different according to serous or mucinous type (46.9 ± 16.7 years and 44.6 ± 17.6 years). Women with SBOT, had more frequently history of infertility (17.2% versus 3.9%, P < 0.0001) than women with MBOT. SBOT were more often asymptomatic (52.3% versus 33.5%, P < 0.001), bilateral (26.4% versus 4.3%, P = 0.0001), smaller (9.1 cm versus 14.5 cm, P = 0.0001) and diagnosed at advanced stage (81.2% of stage I versus 95.1%, P < 0.0001) than MBOT. The micropapillary pattern found in 10.3% of SBOT was observed at younger age (38 ± 15.4 years versus 47.9 ± 16.6 years, P = 0.007) and was more often associated with peritoneal implants (26.1% versus 6.5%, P = 0.02). The intraepithelial carcinoma found in 6.7% of MBOT, was more often associated with micro-invasion (36.4% versus 4.6%, P = 0.003). The existence of epidemiologic differences between SBOT and MBOT underlines that the BOT series analysis can not be considered without taking into account this parameter.
