External Beam Radiation for Prostate Cancer Increases Risk of Hip Fracture


May 30 2010
San Francisco, CA – Patients undergoing three dimensional external beam radiation therapy (3D-EBRT) for prostate cancer may be at an increased risk of hip fracture and could benefit from additional measures to improve bone health following treatment, according to a study from researchers in Minneapolis. The data was presented during the 105th Annual Scientific Meeting of the American Urological Association (AUA).

Fractures can impact a patient’s quality of life and mortality, and fracture risk is a well-known concern in prostate cancer patients who undergo androgen suppression therapy (AST), which is known to weaken bones. EBRT has been shown to increase hip-fracture risk in women, and researchers explored whether EBRT impacted a man’s risk and, if so, whether this effect extended beyond the radiation field.

Researchers identified 166,162 prostate cancer patients, ages 66 years and older, in the Surveillance, Epidemiology and End Results (SEER) database and compared hip fracture risk (inside the radiation field) vs. wrist fracture risk (outside the radiation field) in those who had undergone EBRT and those who had not. After controlling for those who were undergoing AST, as well as other risk factors including osteoporosis, race and age, researchers determined that undergoing EBRT increased a man’s risk of hip fracture by 58 percent, without increasing the risk of wrist fracture. Patients being treated with AST had an increased risk of both types of break.

“Maintaining bone health is an important part of treating prostate cancer patients, particularly those on AST,” said Jeff Holzbeierlein, MD, an AUA spokesman. “These data suggest that we might consider taking similar measures with our patients who are receiving three dimensional external beam radiation therapy.”

WELL, I HADN'T HEARD OF THIS AND I JUST FINISHED MY ADJUVANT RADIATION THERAPY!! I GUESS I WILL JUST ADD IT THE LIST OF POSSIBLE SIDE EFFECTS AND HOPE FOR THE BEST. THANKS FOR THE INFO--DAN
