OBJECTIVE: To determine the influence of maximal androgen blockade (MAB) on bone mineral density (BMD) in men with prostate cancer.
METHODS: We enrolled 40 men with prostate cancer treated by MAB for 7 to 12 months. We obtained the laboratory results of PSA, testosterone, serum calcium and phosphorus, 24-h urine calcium and phosphorus, alkaline phosphatase, and parathyroid hormone, measured the BMD of the lumbar spine and femoral neck by dual energy X-ray absorptiometry, recorded pain scores, and compared the results before and after the treatment.
RESULTS: Before MAB treatment, 5 (12.5%) of the patients met the BMD criteria of lumbar spine (L2-4) osteopenia, 8 (20%) lumbar spine (L2-4) osteoporosis, 13 (32.5%) left femoral neck osteopenia, and 15 (37.5%) left femoral neck osteoporosis. The PSA and testosterone levels were decreased from (52.9 +/- 69.9) microg/L and (18.9 +/- 6.5) nmol/L before MAB to (1.5 +/- 1.6) microg/L and (1.9 +/- 1.3) nmol/L after it (P<0.05). There were no statistically significant differences before and after MAB in the levels of serum calcium and phosphorus, 24-h urine calcium and phosphorus, alkaline phosphatase, and parathyroid hormone (P>0.05), nor in the BMD levels of the lumbar spine ([1.1 +/- 0.1] vs [1.1 +/- 0.2] g/cm2) and femoral neck ([0.8 +/- 0.2] vs [0.8 +/- 0.1] g/cm2), nor in the pain score ([0.6 +/- 0.2] vs [0.7 +/- 0.1], P>0.05).
CONCLUSION: MAB treatment (range from 7 to 12 months) has no significant influence on BMD in men with prostate cancer, but BMD should be measured before MAB.
