title: Circannual rhythms in steroid receptor concentration in gynecologic and breast cancers.
abstract: Both estrogen and progestin receptor concentrations vary in a predictive temporal pattern for breast cancer; in epithelial ovarian cancer a temporal rhythmic pattern is suggested for estrogen receptor concentration only. No pattern for either receptor is seen for endometrial cancer.
