Megestrol in Treating Patients With Endometrial Neoplasia or Endometrial Hyperplasia

Summary
Brief summary (as posted)
This randomized phase II trial is studying how well megestrol works in treating patients with endometrial neoplasia or endometrial hyperplasia. Estrogen can cause the growth of endometrial cancer cells. Hormone therapy using megestrol may fight endometrial cancer by blocking the use of estrogen by the abnormal cells.

Arms (3)
- type
- EXPERIMENTAL
- label
- Regimen 1 (megestrol acetate, surgery)
- description
- Patients receive oral megestrol twice daily every day for 24 weeks. Approximately twelve weeks after treatment starts, clinical blood tests are obtained and research serum and plasma collected. Twenty-four weeks constitutes one course of treatment and a pill count is performed during the 12-week f/u visit and at the completion of the treatment course to determine compliance. After progestin therapy the patient has an induced-withdrawal bleed. Patients in this arm undergo a re-evaluation biopsy and hysterectomy a minimum of two weeks and a maximum of eight weeks after completing the megestrol treatment.

- description
- Patients receive oral megestrol twice daily for two weeks continuously followed by no treatment for two weeks. This course is repeated for a total of 24 weeks. Approximately twelve weeks after treatment starts, clinical blood tests are obtained and research serum and plasma collected. Twenty-four weeks constitutes one course of treatment and a pill count is performed during the 12-week f/u visit and at the completion of the treatment course to determine compliance. After progestin therapy the patient has an induced-withdrawal bleed. Patients in this arm undergo a re-evaluation biopsy and hysterectomy a minimum of two weeks and a maximum of eight weeks after the megestrol treatment.
