Tumor-bone interactions in skeletal metastasis.

Bone metastases are a frequent clinical problem in patients with breast, prostate, and other cancers. Formation of these lesions is a site-specific process determined by multiple cellular and molecular interactions between the cancer cells and the bone microenvironment. Clinical studies, and in vivo and in vitro experimental approaches, have been useful to dissect different stages of this process. Mechanisms identified as relevant to cancer …
