Clinical Trial Summary

RATIONALE: Hormone therapy using medroxyprogesterone may be effective in treating endometrioid cancer.

PURPOSE: This phase II trial is studying how well medroxyprogesterone works in treating patients with endometrioid adenocarcinoma (cancer) of the uterine corpus (the body of the uterus, not including the cervix).


Clinical Trial Description

OBJECTIVES:

- Compare the efficacy of medroxyprogesterone, in terms of induction of histologic response, in patients with progesterone receptor-positive vs progesterone receptor-negative endometrioid adenocarcinoma of the uterine corpus.

- Determine the early and late changes in gene expression at 72 hours and 21 days in patients treated with this drug.

- Examine the mechanisms surrounding the dynamic changes in endometrial tumor cells by determining possible correlations among histologic response, steroid receptor status, immunohistochemical measures of growth and apoptosis, and gene expression profiles in patients treated with this drug.

OUTLINE: This is a pilot, multicenter study.

Patients receive medroxyprogesterone intramuscularly once approximately 3 weeks before surgical hysterectomy.

A subset of 15 patients has tissue collected by pipelle biopsy or curettage at baseline, 72 hours after medroxyprogesterone therapy, and during surgery for gene expression arrays.

Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study. ;
