title: Correlation between bone metabolic markers and bone scan in prostatic cancer.
abstract: OBJECTIVE
  We examined the correlation between bone metabolic markers and bone scintigraphy in prostatic cancer.
  
  
  METHODS
  Osteoblastic and osteoclastic markers, prostate specific antigen (PSA) and bone scans were investigated in 83 specimens from 70 patients with prostatic cancer, including 32 with and 38 without bone metastasis.
  
  
  RESULTS
  All markers except for osteocalcin were significantly greater in patients with than without bone metastasis. Pyridinoline cross-linked carboxyterminal telopeptide, an osteoclastic marker, reflected the extent of bone metastasis more accurately than PSA and other bone markers.
  
  
  CONCLUSIONS
  Pyridinoline cross-linked carboxyterminal telopeptide might assist PSA and bone scintigraphy in monitoring metastatic bone activity of prostatic cancer.
