Inflammation and skeletal metastasis.
Ontology highlight
ABSTRACT: On the road to metastasis a cancer cell has to overcome two major obstacles: the physical escape from the primary tumor to a distant tissue and the adaptation to the new microenvironment via colonization and the formation of a secondary tumor. Accumulated scientific findings support the hypothesis that inflammation is a critical component of the tumor microenvironment and develops as a result of tumor-induced recruitment of inflammatory cells and their reciprocal interaction with other cells from the tumor network. These interactions modulate immune responses to suppress antitumor immunity and activate feedback amplification signaling loops that link nearly all the cells in the cancer inflammatory milieu. The coordinated regulation of cytokines/chemokines, receptors and other inflammatory mediators enables the different steps of the metastatic cascade. As a target organ for colonization, the bone is rich in inflammatory mediators that are critical for successful cancer growth. In this review, we focus on the inflammatory cells, molecules and mechanisms that facilitate the expansion of cancer cells from the primary tumor to their new 'home' in the skeleton.
