title: A case-control study of borderline ovarian tumors: the influence of perineal exposure to talc.
abstract: The authors interviewed 116 female residents of western Washington State with serous and mucinous borderline ovarian tumors diagnosed between 1980 and 1985 and questioned them on their use of hygienic powders. A sample of 158 control women from the same counties were identified through random digit dialing and were interviewed as well. Neither the perineal application of baby powder nor the perineal application of cornstarch was associated with an appreciably altered risk of borderline ovarian tumors. However, women who used deodorizing powders alone or in combination with other talc-containing powders had 2.8 times the risk (95% confidence interval 1.1-11.7) of women who had not had perineal exposure to powder. These results suggest that future studies of ovarian tumors in relation to the application of talc-containing powders should consider ascertaining the specific type(s) of powder used.
