O16 Therapy-Induced Alteration of the Tumor Microenvironment: Impact of Bone Marrow Derived Cells Robert Kerbel 1 1 Molecular & Cellular Biology Research, Sunnybrook Health Sciences Centre, Toronto, Ontario, Canada A common problem associated with cancer therapy using various cytotoxic drugs, including chemotherapy, or other treatments, e.g. radiation, is the property of responding tumors to rapidly repopulate and recover from such therapies (Kim & Tannock, Nat Rev Cancer 2005). This can significantly compromise the progression free and overall survival benefits induced by such therapies. Historically, tumor repopulation has been viewed see more primarily, or exclusively, as an intrinsic tumor cell phenomenon. However, we have obtained evidence for various therapy-induced host responses that can alter
the tumor microenvironment in such a way so as to accelerate tumor repopulation after administering therapies such as maximum tolerated dose (MTD) chemotherapy or ‘vascular disrupting agents’ (Y Shaked et al. Science 2006; ibid Cancer Cell 2008). These host responses consist of the rapid systemic induction of a variety of growth factors, cytokines, and chemokines such as SDF-1 and G-CSF, among others, which then induce mobilization of a variety of bone marrow derived cell (BMDC) types, including circulating endothelial progenitor cells (CEPs). Such cells subsequently home to and invade the drug treated tumors, in potentially large numbers. The molecular mechanisms responsible for CEP tumor homing and retention at the tumor site are under investigation, and several molecular entities have been implicated including CXCR4/SDF-1, a4b1
integrin, G-CSF, and VE-cadherin. As a result, targeting such molecules to prevent the invasion of tumors by BMDCs Fossariinae becomes a therapeutic option, e.g. targeting CXCR4 or a4b1 concurrently with certain cytotoxic therapies. In addition, certain antiangiogenic drugs such as anti-VEGF(R-2) antibodies may function, at least in part, to enhance MTD chemotherapy or VDA therapy by reducing aspects of the host bone marrow ‘tumor response’, either by preventing mobilization, tumor homing, or retention at the tumor site.
