Breast Cancer Survivors May Face Early Hip Fracture Risk

“Their health care costs may increase and their fractures contribute to losing some independence.”

Edwards said she was surprised to find that the majority of the women did not have osteoporosis, but did have lower than normal bone mineral density (osteopenia). This suggests that rapid change in bone architecture from chemotherapy, early menopause and adjuvant therapy may not be evident on bone mineral density tests, she added.

The women had early stage breast cancer and received treatment including lumpectomy, radiation therapy and chemotherapy with cytoxan and adriamycin one to four years before the fracture occurred. They were all perimenopausal at the time of the fracture.

Four of the six women had breast cancer that grew in response to estrogen and received aromatase inhibitors (AIs) as part of their cancer therapy to block their bodies from making estrogen. Recent studies have linked AIs with possible bone loss in women.

Edwards’ team also reviewed reports from the Food and Drug Administration's adverse event reporting system and other databases, and found that AIs were the most common drug class associated with hip fractures.

“Although the majority of women with breast cancer can expect to be fully cured from the disease, the prevention of cancer treatment-induced bone loss is important to consider in cancer survival,” Edwards said. “More research needs to be done before treatment guidelines are changed, but greater awareness of the adverse effects of certain breast cancer drugs is needed.”

Edwards said the next step is for researchers to conduct a clinical trial and give bone density screenings to women before they enter breast cancer chemotherapy. High-risk patients would be flagged and given preventive bone loss therapy and monitored for premature hip fractures.

“The pain and suffering and hospital stays and higher health costs associated with these hip fractures might be prevented through early intervention,” Edwards said.
