Study of Bone Mineral Density in Postmenopausal Women After Treatment for Breast Cancer

Breast Cancer Clinical Trial

Official title: A Pilot Study of Bone Mineral Density in Postmenopausal Women After Treatment for Breast Cancer

Status Completed

Clinical Trial Summary

Bone Mineral Density (BMD) as measured by X-ray shows the amount of calcium in the bone. Low BMD may reflect osteoporosis, a condition where there is an increased risk of fracture. Women who have gone through menopause have a higher risk of getting osteoporosis because they lose calcium from their bones much faster than younger women. Women with breast cancer may have an additional risk for getting osteoporosis because of the effects of their treatment with chemotherapy. The purpose of this study is to see what levels of BMD post-menopausal women with breast cancer have, and to see if the level of BMD changes during a women's treatment after her surgery. This trial studies changes in BMD and markers of bone activity in women receiving treatment for early stage breast cancer.

Clinical Trial Description

Breast cancer patients may be at increased risk for osteoporosis secondary to cancer treatment. The hypothesis of this study is that adjuvant chemotherapy increases the risk of osteoporosis in postmenopausal women. The objective of this pilot study is to describe the effects of chemotherapy on bone mineral density and serum markers of bone metabolism.

There is limited data on the change in bone mineral density due to chemotherapy in postmenopausal women. This prospective study will gather data on the effects of systemic breast cancer therapy on bone mineral density in postmenopausal women receiving adjuvant care for early stage (0, I, II or III) breast cancer. Postmenopausal women are the focus of this study because: (1) they are the largest subgroup of women with breast cancer (2) they are expected to have a rate of BMD loss unless disturbed by disease or medications, unlike the pre and perimenopausal women whose BMD is dramatically affected by changes in hormonal status (3) this group of patients is at greatest risk for acute osteoporotic fractures. ;
