[Mechanism of cancer-induced bone pain].
Bone pain is one of the major complications of bone metastases and profoundly deteriorates quality of life in cancer patients. It has been suggested that the nerve injuries by tumor invasion and the inflammatory factors secreted by cancer cells are involved in the pathophysiology of bone pain. Recent studies including ours suggest that the activation of acid-sensing receptors by tumor-induced acidosis in bone metastases also plays a part in causing bone pain. In this review, the current understanding of the mechanisms of cancer-induced bone pain is discussed.
