This approach was developed for metastatic neuroendocrine tumors in the early 1970s. Tumor cells get over 90% of their nutrients from the hepatic artery, while the normal cells of the liver get about 70-80 percent of their nutrients and 50% their oxygen supply from the portal vein, and thus can survive with the hepatic artery effectively blocked. Once the catheter is carefully placed in the artery or in a selected branch, the blood
