Brief summary

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

Detailed description

PRIMARY OBJECTIVES: I. 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. II. Determine the early and late changes in gene expression at 72 hours and 21 days in patients treated with this drug. III. 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.

Histologic Response in Endometrial Adenocarcinomas of the Uterine Corpus That Are Progesterone Receptor Positive Compared With Those That Are Progesterone Receptor NegativeDuring the hysterectomy, which is 21-24 days after administration of depo-proveraTo determine the presence of a histologic response, the slide from the initial sample was compared to the slide from the matching hysterectomy specimen. A complete histologic response was defined as the absence of identifiable adenocarcinoma in the hysterectomy specimen section. A partial histologic response was subjectively defined in advance of the study based on criteria slightly modified from Wheeler et al. (Am J Surg Pathol 2007;31:988-98) as the presence of a complex proliferation of glands that retain the architectural characteristics of adenocarcinoma, but with features of secretion, decreased nuclear stratification, or the presence of eosinophilic, squamous or mucinous metaplasia, when this was absent in the initial sample. A complete or partial histologic response was considered a histologic response in the analysis of data. PR Positivity is based on aggregate score \>0.2 (vs. \<=0.2).

Histologic Response in Endometrial Adenocarcinomas of the Uterine Corpus That Are Progesterone Receptor Positive Compared With Those That Are Progesterone Receptor Negative

To determine the presence of a histologic response, the slide from the initial sample was compared to the slide from the matching hysterectomy specimen. A complete histologic response was defined as the absence of identifiable adenocarcinoma in the hysterectomy specimen section.
