Charleston Radiologists is one of only two Therasphere treatment sites in South Carolina, and the only site in the greater Charleston area. Transarterial Radioembolization with Therasphere is a minimally invasive outpatient cancer treatment for patients with primary liver cancers (hepatocellular carcinoma and cholangiocarcinoma) and liver dominant metastases. Tiny particles which emit high energy radiation (Yttrium-90) are injected through the blood vessels that supply the liver and act locally to kill tumors in the liver while causing minimal to no systemic side effects. Shown to slow disease progression and improve survival and quality of life, Transarterial Radioembolization with Thermasphere can be used to downstage certain patients to curative resection or liver transplantation. The interventional procedure is minimally invasive and can be combined with systemic chemotherapy to provide synergistic anti-tumoral effects.
