Study of Statin as Neo-Adjuvant Therapy in Postmenopausal Breast Cancer

Lund University Hospital50 enrolled

Overview

The purpose of this study is to monitor: * Tumor biological alterations following two weeks of neo-adjuvant statin therapy. * Effects of statins on tumor proliferation. * Functional studies on the mevalonate pathway.

Blood samples and three core biopsies are taken after diagnosis. Treatment with atorvastatin at a daily dosis of 80 mg is initiated 14 days before planned surgery. Translational research will be performed from the core biopsy and blood samples taken before surgery and from the specimen from surgery.
