Bone mets and ca27.29

BACKGROUND: The assessment of bone metastases by clinical examination or imaging techniques is still considered unreliable. We compared a specific marker of bone resorption, urinary deoxypyridinoline (DPD)-crosslinks, with serum calcium (Ca), alkaline phosphatase (AP) and CA27.29, to evaluate the status of bone metastases in patients with breast cancer. MATERIALS AND METHODS: Second morning voided urine was collected from 2 groups of patient (pts), those without evidence of disease (n = 118), and those with bone metastases (n = 85) under specific therapy plus pamidronate...
