Cramer and co-workers1 recently reported observing an association between talc use and risk of ovarian cancer. We therefore examined data on talc use that two of us (L.M. and L.P.L.) had collected as part of a case-control interview study of epithelial ovarian cancer conducted from 1974 to 1977 in the Washington, DC, area.2 The cases were 197 women with pathologically confirmed primary epithelial ovarian cancers treated in participating hospitals.
