RATIONALE: The use of intrauterine levonorgestrel may prevent atypical endometrial hyperplasia and endometrial cancer in women with hereditary non-polyposis colorectal cancer or Lynch syndrome. It is not yet known whether intrauterine levonorgestrel and observation are more effective than observation alone in preventing atypical endometrial hyperplasia and endometrial cancer in women with hereditary non-polyposis colorectal cancer or Lynch syndrome.

PURPOSE: This randomized phase III trial is studying intrauterine levonorgestrel and observation to see how well they work compared with observation alone in preventing atypical endometrial hyperplasia and endometrial cancer in women with hereditary non-polyposis colorectal cancer or Lynch syndrome.

Primary Outcome Measures:
  • Rate of atypical endometrial hyperplasia or endometrial cancer during the active follow-up period of the study

Estimated Enrollment: 600
Study Start Date: July 2007
Study Completion Date: August 2009
Primary Completion Date: October 2008 (Final data collection date for primary outcome measure)
Detailed Description:



  • To determine if treatment with intrauterine levonorgestrel (using the Mirena® intrauterine system [IUS]) reduces the incidence of atypical endometrial hyperplasia (AEH) and endometrial cancer in women with hereditary non-polyposis colorectal cancer or Lynch syndrome.


  • Determine the age-related incidence of AEH and endometrial cancer in these patients.
  • Determine the sensitivity and specificity of transvaginal sonography and endometrial biopsy in detecting AEH and endometrial cancer.
  • Determine the premalignant pathway to carcinoma.
  • Determine if the Mirena® IUS reduces the rate of therapeutic hysterectomy for AEH or endometrial cancer.
  • Determine the psychological benefits or adverse effects from the use of the Mirena® IUS.
  • Determine the satisfaction and compliance with screening.
  • Determine the extent of adverse effects of the Mirena® IUS and observation.
  • Determine the molecular changes associated with pre-malignant changes in the endometrium of these patients, and possibly the utility of tests on cervical mucus samples in diagnosing endometrial cancer.

OUTLINE: This is a multicenter study. Patients are stratified by center and menopausal status. Patients are randomized to 1 of 2 arms.

  • Arm I: Patients undergo insertion of the Mirena® intrauterine device containing levonorgestrel. The device is scheduled to remain in place for 4 years. Patients also undergo observation comprising an assessment of menstrual history, transvaginal scanning (TVS), and endometrial biopsy (or hysteroscopy) at baseline and then annually for 4 years.
  • Arm II: Patients undergo observation comprising an assessment of menstrual history, TVS, and endometrial biopsy (or hysteroscopy) at baseline and then annually for 4 years.

Patients complete a personal health and lifestyle questionnaire, the Life Events Scale, and the Profile of Mood States (POMS) questionnaires at baseline and periodically during study.
