Résumé : | [BDSP. Notice produite par INIST-CNRS m9p8R0x7. Diffusion soumise à autorisation]. Background Tubal ligation is a protective factor for ovarian cancer, but it is unknown whether this protection extends to all invasive histological subtypes or borderline tumors. We undertook an international collaborative study to examine the association between tubal ligation and ovarian cancer subtypes. Methods We pooled primary data from 13 population-based case-control studies, including 10 157 patients with ovarian cancer (7942 invasive ; 2215 borderline) and 13 904 control women. Invasive cases were analysed by histological type, grade and stage, and borderline cases were analysed by histological type. Pooled odds ratios were estimated using conditional logistic regression to match on site, race/ethnicity and age categories, and to adjust for age, oral contraceptive use duration and number of full-term births. Results Tubal ligation was associated with significantly reduced risks of invasive serous (OR, 0.81 ; 95% CI, 0.74-0.89 ; P<0.001), endometrioid (OR, 0.48 ; 95% CI, 0.40-0.59 ; P<0.001), clear cell (OR, 0.52 ; 95% CI, 0.40-0.67 ; P<0.001) and mucinous (OR, 0.68 ; 95% CI, 0.52-0.89 ; P=0.005) cancers. |
