Transarterial bland embolization (TAE, also known as HAE) is a catheter-based tumor treatment of the liver.In this procedure, embolizing agents (e.g., polyvinyl alcohol, gelfoam, acrylic copolymer gelatin particles, embospheres) can be delivered through the tumor's feeding artery in order to completely occlude the tumor's blood supply.
Hepatic arterial infusion (HAI) is a medical procedure that delivers chemotherapy directly to the liver.The procedure, mostly used in combination with systemic chemotherapy, plays a role in the treatment of liver metastases in patients with colorectal cancer (CRC). [1]
Although there is no consensus to the absolute minimum liver volume required for adequate post-resection liver function, a FLR/TELV ratio of at least 25% is recommended in patients with otherwise normal livers. [2] The recommendation for those with chronic liver disease such as cirrhosis is a FLR/TELV ratio of at least 40%. In these patients a ...
The several types of hepatic artery treatments are based on the observation that tumor cells get nearly all 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.

TACE of liver tumors derives its beneficial effect by two primary mechanisms. [3] Most tumors within the liver are supplied by the proper hepatic artery, so arterial embolization preferentially interrupts the tumor's blood supply and stalls growth until neovascularization. Secondly, focused administration of chemotherapy allows for delivery of ...
Gastric (stomach) cancer: Routine screening is not typically recommended in the United States, other than in high-risk populations. Cervical cancer : Screening typically starts at age 21 with a ...
After four months of pre-surgery chemotherapy, a 12-hour surgery to resect her liver and another eight weeks of chemotherapy, Mia reached remission on July 25, 2022. Unfortunately, she relapsed ...
Radiation therapy is used to kill cancer cells; however, normal cells are also damaged in the process. Currently, therapeutic doses of radiation can be targeted to tumors with great accuracy using linear accelerators in radiation oncology; however, when irradiating using external beam radiotherapy, the beam will always need to travel through healthy tissue, and the normal liver tissue is very ...
