Medroxyprogesterone in Treating Patients With Endometrioid Adenocarcinoma of the Uterine Corpus

2014-08-27 03:55:07 | BioPortfolio

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).

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.

Medical and Biotech [MESH] Definitions

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).
