S0511, Goserelin and Anastrozole in Treating Men With Recurrent or Metastatic Breast Cancer

• Status: Withdrawn
• Trial end date: 2007-01-01
• Target enrollment: 0
• Participant gender: Male

Summary

RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using goserelin and anastrozole may fight breast cancer by blocking the use of estrogen by the tumor cells. Giving goserelin together with anastrozole may be an effective treatment for male breast cancer.

PURPOSE: This phase II trial is studying how well giving goserelin together with anastrozole works in treating men with recurrent or metastatic breast cancer.

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