Observational Triveneto Study on the Use of Adjuvant Hormonal Therapies in the Treatment of Hormone-responsive Breast Cancer

Retrospective Observational Triveneto Study on the Use of Adjuvant Hormonal Therapies in the Treatment of Hormone-responsive Breast Cancer in Two Successive Time Periods

There are different types of hormonal therapy medicines for the treatment of hormone-receptor-positive breast cancer. The purpose of this study is to determine the evolution of two types of hormonal treatment (the drug called "tamoxifen" and a group of medicines called "aromatase inhibitors") during two time periods of 12 months each, in years 2006 and 2008, in the northeast Italian regions. The study will include post-menopausal women who have initiated hormonal therapy medicines in 2006. The study will also verify the rate of implementation of the updated national and international recommendations for the use of adjuvant hormonal therapy in the hormone-receptor-positive breast cancer.

Inclusion Criteria:

• Post-menopausal patients with surgically treated breast cancer who started adjuvant hormonal therapy between January 2006 and December 2006 or between January 2008 and December 2008
• Documented evidence of the way adjuvant hormonal treatment was initiated.

Exclusion Criteria:

• Pre- or peri-menopausal patients with surgically treated breast cancer who started adjuvant hormonal therapy
• Patients already enrolled in clinical studies aimed at investigating hormone therapies
