Embolization refers to the passage and lodging of an embolus within the bloodstream. It may be of natural origin (pathological), in which sense it is also called embolism, for example a pulmonary embolism; or it may be artificially induced (therapeutic), as a hemostatic treatment for bleeding or as a treatment for some types of cancer by deliberately blocking blood vessels to starve the tumor ...
Hence, arterial treatment targets the tumor while normal liver is relatively spared. Embolization induces ischemic necrosis of tumor causing a failure of the transmembrane pump, resulting in a greater absorption of cytotoxic agents by the tumor cells. Tissue concentration of agents within the tumor is greater than 40 times that of the ...
1990s – Treatment of bone and kidney tumors by embolization. 1990s – RFA for soft tissue tumors, i.e., bone, breast, kidney, lung and liver cancer. 1997 – Intra-arterial delivery of tumor-killing viruses and gene therapy vectors to the liver. 1997 – HIFU first used to treat prostate cancer.
Liver cancer: primary liver tumors such as hepatocellular carcinoma or cholangiocarcinoma and liver metastases are often treated by procedures such as transarterial chemoembolization (TACE), Selective internal radiation therapy (SIRT/Y-90 radioembolization), portal vein embolization, transarterial/bland embolization, or image guided ablation ...
The findings suggest IL1B macrophages could be a promising therapeutic target to treat kidney cancer, given this cell type has already been targeted using existing drugs that prevent lung cancer.
“Patients with Stage 3 or 4 kidney cancer are at high risk of recurrence,” Dr. Toni Choueiri, director of Dana-Farber’s Lank Center for Genitourinary Cancer, said in a news release about the ...
Arterial embolism can cause occlusion in any part of the body. It is a major cause of infarction (tissue death from blockage of the blood supply). [4] An embolus lodging in the brain from either the heart or a carotid artery will most likely be the cause of a stroke due to ischemia. [5]
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 ...
