UNLABELLED: Men treated by androgen deprivation therapy (ADT) for localized prostate cancer are at risk for fracture, but it is not known which men require pharmacologic treatment. We found that 33% of men on ADT had osteoporosis of spine, hip, or forearm by dual-energy X-ray absorptiometry (DXA), thus requiring treatment. Using the new fracture prediction algorithm (FRAX) tool with corrected femoral neck T-score identified only 17% requiring treatment, and, if calculated without femoral neck, 54% were identified to need treatment.
INTRODUCTION: Men treated with androgen deprivation therapy (ADT) for prostate carcinoma live long enough to fracture. A new fracture prediction method, FRAX, is based on femoral neck DXA plus risk factors. Thus, DXA or FRAX could determine which men should receive osteoporosis therapy.
METHODS: Of 115 men undergoing ADT referred for DXA testing, those with bone mineral density (BMD) in spine, hip, or forearm of >or=2.5 standard deviations below a normal male ethnicity-adjusted mean were considered treatment candidates. Using FRAX with and without femoral neck BMD, men were treatment candidates if the 10-year hip fracture risk was >or=3% or the major osteoporotic fracture risk was >or=20%.
RESULTS: The men averaged 77 years old; 58% were African-American, and 14.8% were current smokers. Mean femoral neck T-score was -1.4. Using DXA, 38 (33%) men would need treatment. When FRAX was calculated including the femoral neck T-score, only 20 men met criteria for treatment. However, when FRAX was calculated without the T-score, 62 men met criteria for treatment. Overlap among the groups was surprisingly modest.
CONCLUSIONS: DXA and FRAX identify different ADT men for treatment.
