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).
- 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.
Primary Purpose: Treatment
medroxyprogesterone, microarray analysis, conventional surgery, neoadjuvant therapy

Controversy exists over the optimal neoadjuvant therapy in patients with locally advanced esophageal cancer (EC). While most groups favor neoadjuvant chemoradiation (nCRT), some prefer preoperative ch...

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
The simultaneous analysis, on a microchip, of multiple samples or targets arranged in an array format.
Therapeutic practices which are not currently considered an integral part of conventional allopathic medical practice. They may lack biomedical explanations but as they become better researched some (PHYSICAL THERAPY MODALITIES; DIET; ACUPUNCTURE) become widely accepted whereas others (humors, radium therapy) quietly fade away, yet are important historical footnotes. Therapies are termed as Complementary when used in addition to conventional treatments and as Alternative when used instead of conventional treatment.
A synthetic progestin that is derived from 17-hydroxyprogesterone. It is a long-acting contraceptive that is effective both orally or by intramuscular injection and has also been used to treat breast and endometrial neoplasms.
Neoplasms of the endometrial stroma that sometimes involve the MYOMETRIUM. These tumors contain cells that may closely or remotely resemble the normal stromal cells. Endometrial stromal neoplasms are divided into three categories: (1) benign stromal nodules; (2) low-grade stromal sarcoma, or endolymphatic stromal myosis; and (3) malignant endometrial stromal sarcoma (SARCOMA, ENDOMETRIAL STROMAL).

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
