The biology of metastasis to a sanctuary site.
Metastasis to the brain is prevalent in solid tumors and lymphomas, and is associated with shortened survival. The brain is regarded as a sanctuary site for metastatic tumor cells where they exist partially protected from drugs by the blood-tumor barrier. Model systems for brain metastasis have been developed and are now yielding mechanistic insights into the roles of angiogenesis, energy metabolism, the Her-2 and Stat3 signaling pathways, and dormancy. Specific, new approaches to combat brain metastatic disease are needed.
