Pretreatment levels of urinary deoxypyridinoline as a potential marker in patients with prostate cancer with or without bone metastasis

Objective To assess the predictive role of the bone markers alkaline phosphatase (ALP) and urinary deoxypyridinoline (DPD), as indicators of bone turnover, at baseline in patients with prostate cancer. Patients, subjects and methods Urinary DPD, serum ALP and prostate‐specific antigen (PSA) were eva...

Description
Summary:Objective To assess the predictive role of the bone markers alkaline phosphatase (ALP) and urinary deoxypyridinoline (DPD), as indicators of bone turnover, at baseline in patients with prostate cancer. Patients, subjects and methods Urinary DPD, serum ALP and prostate‐specific antigen (PSA) were evaluated in 23 patients with benign prostatic hyperplasia (BPH), 115 with prostatic carcinoma, of whom 21 had bone metastasis, and in 16 age‐matched control subjects. Results Patients with newly diagnosed prostate cancer and bone metastasis had a higher urinary excretion of DPD, and a higher serum PSA and ALP than had patients with BPH and those with prostate cancer but no metastasis. Receiver operating curve analysis for PSA, ALP and DPD showed a significant discriminating ability for positive and negative bone scans (P = 0.0684). However, from logistic regression of the combinations, only serum ALP was a significant independent predictor of bone metastasis in patients with prostate cancer. Conclusion Serum ALP or urinary DPD are the best predictors of bone metastasis in patients with prostate cancer; further studies with more patients are required.
