Significance of Tumor Microenvironment on the Genesis of: Interstitial Fluid, Angiogenesis, Haemostatic/Haemorheologic Abnormalities. Pathogenesis and Therapeutic Aspects

Solid tumours tend to have e more acidic and hypoxic microenvironment then normal tissue. This hostile microenvironment results from a disparity between oxygen supply and demand of the tumor tissue. Overcoming hypoxia tumor induces e new vascular supply. This new vasculature is however inefficient and chaotic. It perpetuates the factors that have stimulated its induction. This review focuses on these processes and peculiarly on angiogenesis, tumor vascular morphology, hypoxia, pH, and the metabolic-vascular events induced or following rumour tissue heating. The various mechanisms that either modulate tumor micrenvironments blood perfusion during hyperthermia are described, providing also the many clinical modalities that may enhance or sensitize cancer cells to heat.
