  • Endometrial Cancer


RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of surgery with or without medroxyprogesterone may be an effective way to prevent the development of endometrial cancer in patients who have endometrial hyperplasia. PURPOSE: Phase II trial to compare the effectiveness of surgery alone with that of medroxyprogesterone followed by surgery in preventing endometrial cancer in patients who have endometrial hyperplasia.

Study summary:

OBJECTIVES: - Determine the joint occurrence of atypical hyperplasia and adenocarcinoma in patients diagnosed at initial biopsy to have complex atypical hyperplasia. - Compare the histologic response rates in patients with atypical endometrial hyperplasia treated with oral medroxyprogesterone acetate (Provera) vs intramuscular medroxyprogesterone acetate suspension (Depo-Provera) . OUTLINE: This is a randomized, two-part study. - Part A: Patients undergo immediate hysterectomy. - Part B: Patients are randomized to 1 of 2 arms. - Arm I: Patients receive oral medroxyprogesterone acetate (Provera) once daily for 3 months. - Arm II: Patients receive medroxyprogesterone acetate suspension (Depo- Provera) intramuscularly once monthly for 3 months (days 1, 31, and 62). Patients undergo hysterectomy at the end of the third month. Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter. PROJECTED ACCRUAL: A minimum of 360 patients for part A and 140 patients (70 per arm) for part B will be accrued for this study.


DISEASE CHARACTERISTICS: - Histologically confirmed atypical endometrial hyperplasia with recommended treatment with either: - An immediate hysterectomy (Part A) OR - A three-month delay prior to hysterectomy and a randomized choice of treatment with oral medroxyprogesterone acetate (Provera) or medroxyprogesterone acetate suspension (Depo-Provera) during the 3 months (Part B with arms I and II) - Diagnosed by dilation and curettage, Novak curettage, Vabra aspirate or Pipelle endometrial biopsy - No recognized endometrial carcinoma - Must not be considered inoperable PATIENT CHARACTERISTICS: Age: - Not specified Performance status: - GOG 0-2 Life expectancy: - Not specified Hematopoietic: - WBC at least 3,000/mm^3 - Platelet count at least 100,000/mm^3 - Granulocyte count at least 1,500/mm^3 Hepatic: - Bilirubin no greater than 1.5 times normal - SGOT no greater than 3 times normal - Alkaline phosphatase no greater than 3 times normal Renal: - Creatinine no greater than 2 times normal Cardiovascular - No prior thrombophlebitis or thromboembolic phenomena - No prior cerebrovascular disorders Other: - No prior or concurrent malignancy except nonmelanoma skin cancer or carcinoma in situ of the uterine cervix - Not pregnant or nursing - Negative pregnancy test - Fertile patients must use effective contraception PRIOR CONCURRENT THERAPY: Biologic therapy: - Not specified Chemotherapy: - Not specified Endocrine therapy: - See Disease Characteristics Radiotherapy: - Not specified Surgery: - See Disease Characteristics
