Vasculogenesis

Introduction The traditional concept of vasculogenesis in cancer maintains that malignant tumors prefer aerobic metabolism for growth. This theory posits that after continued proliferation, the tumor will “outgrow” its arterial vascular supply; as the resulting hypoxia ensues, the tumor will become dormant. The traditional vasculogenesis theory therefore states that tumors will reinitiate growth only after arteriogenesis occurs, allowing adequate blood flow to restore normoxia. Unfortunately, tumor…

Image-Guided Ablation of Parenchymal Organs

Introduction Image-guided tumor ablation is a minimally invasive strategy to treat a range of focal tumors by inducing irreversible cellular injury through the application of thermal and more recently nonthermal energy or chemical injection. This approach is being used to treat a range of focal tumors, most commonly primary and secondary malignancies of the liver, lung, kidney, adrenal glands, and bone. Specific advantages of percutaneous tumor…
