Primary Outcome Measures:
  • Best pathologic response rates [ Time Frame: up to 24 months ] [ Designated as safety issue: No ]
    The time is for each patient. Patients will be reevaluated for response every 12 weeks

Secondary Outcome Measures:
  • toxicity and tolerability duration of response [ Time Frame: up to 36 months ] [ Designated as safety issue: Yes ]
  • Duration of response [ Time Frame: up to 4 years ] [ Designated as safety issue: No ]
    For each patient, assessed every 12 weeks during treatment and every 6 months during follow-up.

  • rate of pregnancy [ Time Frame: up to 3 years after the treament for each patient ] [ Designated as safety issue: No ]

Enrollment: 31

Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Megestrol Acetate
80 mg (2 tablets) orally at breakfast, 80 mg at dinner for at least 12 weeks
Drug: Megestrol Acetate
Other Name: Megace

Detailed Description:

The trial's objectives are to study the efficacy, defined as complete pathologic resolution of disease, of a standard hormonal regimen with the progestin Megestrol Acetate (MegaceR) for the treatment of atypical endometrial hyperplasia or well or moderately differentiated endometrial carcinoma in women desiring conservative medical management of these conditions in the Women's Cancer Program at the NYU School of Medicine and at the Bellevue Gynecologic Oncology clinics.

The major endpoint is pathologic complete response (pCR). For the purposes of this study, patients will be reevaluated for response every 12 weeks until complete response.

Response will be assessed within 4 weeks of completion of 12 weeks of Megace, by endometrial biopsy or D&C/hysteroscopy. An endometrial biopsy is sufficient to document progressive, stable disease or partial response. A D&C is necessary to confirm complete response

Patients whose disease has completely responded will discontinue treatment and be encouraged to pursue fertility. Those not desiring immediate fertility will be placed on low dose ocp's for at least 6 months.

Patients who have had either a partial response or stable disease will be recounseled and offered continued medical management or surgical therapy.

Patients whose disease has progressed will be offered definitive surgical management. Those patients declining surgery will still be followed on study.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Women with a diagnosis of atypical endometrial hyperplasia or G1 or G2 endometrial carcinoma confirmed by an NYU pathologist desiring medical management will be eligible. The diagnosis may be obtained either by endometrial biopsy or D&C. If diagnosis has been made outside of NYU, slides must be available for review.
  • Age > = 18 years.
  • Life expectancy of greater than 12 months.
  • GOG performance status score of 0, 1 or 2
  • Patients must have normal organ and marrow function as defined below:

    • leukocytes > = 3,000/mcL
    • platelets > = 100,000/mcL
    • total bilirubin within normal institutional limits
    • AST(SGOT)/ALT(SGPT) no greater than 2.5 X institutional upper limit of Normal
    • glucose < 200 mg/dl
    • creatinine within normal institutional limits OR
    • creatinine clearance > = 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal
  • Eligibility of patients receiving any medications or substances known to affect or with the potential to affect the activity or pharmacokinetics of Megace will be determined following review of their case by the Principal Investigator.
  • The effects of Megace on the developing human fetus at the recommended therapeutic dose are unknown. For this reason and because Megace is known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
  • Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

  • Patients with a histological diagnosis of clear cell, papillary serous or poorly differentiated (G3) endometrial carcinoma.
  • Patients with cancer have an MRI showing evidence of extrauterine spread or myometrial invasion.
  • Presence of US findings suspicious for ovarian malignancy, unclear endometrial primary or recurrent endometrial cancer.
  • Patients receiving other investigational agents.
  • Patients with a history of a previous thrombotic event, known thrombophilic condition or poorly controlled diabetes.
  • Patients with a history of breast cancer or other hormonally responsive malignancy.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • Pregnant women are excluded from this study because Megace has the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with Megace, breastfeeding should be discontinued if the mother is treated with Megace.
