Abstract

The present invention relates to methods for preventing the development of epithelial ovarian cancer by administering a Vitamin D compound in an amount capable of increasing apoptosis in non-neoplastic ovarian epithelial cells of the female subject.

Claims

1. A method of increasing apoptosis in non-neoplastic ovarian epithelial cells of a female subject in need thereof comprising administering to a female subject a Vitamin D compound sensitive to induce apoptosis in an amount effective to induce apoptosis in non-neoplastic ovarian epithelial cells of the female subject.

2. The method of claim 1 wherein Vitamin D compound is administered at a dosage equivalent of from 0.0001 to 1.0 mg 1,25-dihydroxyvitamin D₃ /kg of body weight.

3. The method of claim 2 wherein Vitamin D compound is administered at a dosage equivalent of from 0.005 to 0.1 mg/kg 1,25-dihydroxyvitamin D₃ of body weight.

4. The method of claim 1 wherein the Vitamin D compound is 1,25-dihydroxyvitamin D₃.

5. The method of claim 1 wherein the female subject is at high risk of developing ovarian cancer.

6. The method of claim 1 wherein said non-neoplastic cells are dysplastic cells.
