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 ...
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 ...
It may also be used to help protect patients with head, breast, or neck cancer from external beam radiation during treatment. Results from the largest, most comprehensive study to date evaluating SIRT in liver metastases from colorectal cancer were presented at ASCO in 2012, ASCO-GI 2013, and ASCO in 2014.
SIR-Spheres microspheres are used to treat patients with unresectable liver cancer. These are mostly patients with hepatocellular carcinoma (HCC), metastatic colorectal cancer (mCRC), or metastatic neuroendocrine tumours (mNET). [1] Therapy goals are local disease control, downstaging to resection, bridging to transplantation, and extended ...
The most common side effects of Sorafenib include a hand-foot skin reaction and diarrhea. [76] Sorafenib is thought to work by blocking growth of both tumor cells and new blood vessels. Numerous other molecular targeted drugs are being tested as alternative first- and second-line treatments for advanced HCC, such as lenvatinib and regorafenib. [77]
Embolization is a process in which the interventional radiologist accesses the culprit bleeding vessel via a small catheter and interrupts blood flow to the site of bleeding via various mechanisms. Side effects of this procedure are minimal but there is a risk of bleeding and infection—though much less than the equivalent surgical procedure.
By creating a shunt from the portal vein to the hepatic vein, this intervention allows portal blood an alternative avenue for draining into systemic circulation. In bypassing the flow-resistant liver, the net result is a reduced pressure drop across the liver and a decreased portal venous pressure. Decreased portal venous pressure in turn ...
Carbon ion radiotherapy has increasingly garnered scientific attention as technological delivery options have improved and clinical studies have demonstrated its treatment advantages for many cancers such as prostate, head and neck, lung, and liver cancers, bone and soft tissue sarcomas, locally recurrent rectal cancer, and pancreatic cancer ...
