Breast cancer commonly metastasizes to bones, producing both osteolytic and osteoblastic deposits. Different markers for quantitative determination of bone turnover have been developed to evaluate bone metastases of breast cancer. The urinary deoxypyridionline, a crosslink product of collagen molecules found in bone and excreted in urine during bone degradation, and bone specific alkaline phosphatase, an isoenzyme localized in the membrane of osteoblasts and released in circulation during bone formation, were recently described as a group of markers of bone turnover in metastatic cancer.

乳癌患者常见骨髓转移造成溶骨性及成骨性沈积物，而利用不同标记来定量骨质转换形态，可以评估乳癌骨骼转移的变化，而尿液中Deoxypyridinoline是骨质内胶原分子在骨骼破坏分解时至尿中的产物，骨特殊碱性磷酸酵素是一种同形酵素，位於成骨细胞的外膜且在骨骼形成时释放至血液中，利用此两种生化标记，可以来预测乳癌转移至骨骼的转换情形。
