The effect of tamoxifen or exemestane on bone mineral density during the first 2 years of adjuvant treatment of postmenopausal women with early breast cancer.

Background: Adjuvant therapy with aromatase inhibitors is associated with increased bone loss in postmenopausal women with breast cancer. We assessed changes in bone mineral density (BMD) from baseline to 24 months in patients receiving either tamoxifen (T) or exemestane (E).

Patients And Methods: A total of 578 women randomly assigned to T 20 mg per day orally or E 25 mg/day orally enrolled in this substudy; baseline, 12-month, and 24-month BMD measurements of the femur and lumbar spine by dual-energy x-ray absorptiometry were planned.

Risk counseling and management in patients with lobular carcinoma in situ.

Background: The understanding of lobular carcinoma in situ (LCIS) has evolved since it was first described. LCIS once was thought to be a premalignant condition, but now it is considered a marker for increased risk for developing invasive breast cancer. We evaluated patient perception of risk, counseling, and subsequent management.
