    Intravascular Survival and Extravasation of Tumor Cells.

    Cancer Cell 2017 Sep;32(3):282-293

    Most metastasizing tumor cells reach distant sites by entering the circulatory system. Within the bloodstream, they are exposed to severe stress due to loss of adhesion to extracellular matrix, hemodynamic shear forces, and attacks of the immune system, and only a few cells manage to extravasate and to form metastases. We review the current understanding of the cellular and molecular mechanisms that allow tumor cells to survive in the intravascular environment and that mediate and promote tumor cell extravasation. As these processes are critical for the metastatic spread of tumor cells, we discuss implications for potential therapeutic approaches and future research.

    Circulating Tumor Cells: When a Solid Tumor Meets a Fluid Microenvironment.
    Adv Exp Med Biol 2016 ;936:93-106

    Solid tumor dissemination from the primary site to the sites of metastasis involves tumor cell transport through the blood or lymph circulation systems. Once the tumor cells enter the bloodstream, they encounter a new hostile microenvironment. The cells must withstand hemodynamic forces and overcome the effects of fluid shear. Read More

    Cancer cells are shed into the blood stream and are exposed to hemodynamic shear stress during metastasis. It has been shown that shear stress can destroy circulating tumor cells (CTCs) both in vitro and in vivo. However, it remains unclear whether shear stress can modulate the properties and functions of tumor cells in a manner that might help CTCs to exit circulation. Read More

    Anoikis is a mode of apoptotic cell death, consequential to insufficient cell-matrix interactions and a critical player in tumor angiogenesis and metastasis. The events involved in tumor cell progression toward metastasis potential are mediated by integrins, which upon engagement with components of the extracellular matrix (ECM), reorganize to form adhesion complexes. Targeting apoptotic players is of immense therapeutic significance since resistance to apoptosis is not only critical in conferring therapeutic failure to standard treatment strategies, but anoikis (apoptosis upon loss of anchorage and detachment from ECM) also plays an important role in angiogenesis and metastasis.

    Metastatic lesions are the leading cause of death among cancer patients. These lesions usually originate from clonal proliferation of single tumor cells dispersed from the primary tumor into the circulation which finally arrest in the capillary bed of distant organs. The microenvironment within the circulation of potential metastatic target organs provides a variety of pro- and anti- metastatic stimuli regulating the onset of organ colonisation by metastatic tumor cells.
