Simvastatin and Anastrozole in Treating Postmenopausal Women With Ductal Carcinoma In Situ or Invasive Breast Cancer

• Status: Completed
• Trial end date: 2011-11-01
• Target enrollment: 0
• Participant gender: Female

Summary

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of simvastatin and anastrozole may stop cancer from forming, growing, or coming back in patients with invasive breast cancer, ductal carcinoma in situ, or a high risk of breast cancer.

PURPOSE: This phase II trial is studying how well giving simvastatin together with anastrozole works in treating postmenopausal women with invasive breast cancer, ductal carcinoma in situ, or a high risk of breast cancer.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
