Abstract
Over the past few years, selective internal radiation therapy (SIRT) has been used clinically for the treatment of non-resectable hepatic metastases in the absence of extrahepatic metastases and in combination with hepatic arterial chemotherapy. The procedure involves using Yttrium-90 microspheres (25–35 u in diameter (fig. 32b. 1), that are injected using a syringe into the hepatic artery via an access route: either a trans-femoral catheter or a permanently implanted hepatic artery port with catheter (fig. 32b.2). Once injected, the spheres travel through the blood stream and target the tumour within the liver, delivering high doses of beta radiation of 0.93 MeV energy, with a maximum 11 mm and mean 2.5 mm penetration distance [1, 2]. Treatment takes around 20–30 minutes and is delivered under mild sedation
