What is SIRT or radioembolization? SIRT, or radioembolization, is a transarterial method for treating hepatic malignancies that involves selective intraarterial delivery of microspheres loaded with a radioisotope. It is a form of intraarterial brachytherapy. The primary mode of action is the emission of radiation and the second mode of action is the embolization of the …
How is response to TAE and TACE monitored? Posttreatment monitoring is performed with contrast-enhanced multiphase computed tomography (CT) or dynamic magnetic resonance imaging (MRI) 4 to 6 weeks after all tumor-bearing areas are treated. If treatment of both lobes of the liver is planned, imaging between sessions may be performed based on operator preference. Signs …
Exclusion criteria/contraindications for TACE in HCC patients Contraindications for TACE can be categorized based on tumor status, liver disease, patient performance status, procedural aspects, and chemotherapy characteristics. Exclusion criteria based on laboratory values are not definitively established. Greater than 50% liver replacement with tumor, bilirubin level of more than 2 mg/dL, a lactate dehydrogenase level …
What is the expected median survival for intermediate HCC patients after TACE? For intermediate HCC patients the expected median survival is 16 months. After TACE, it is approximately 20 months. This fulfills standard oncological criteria for treatment efficacy.
Indications for TACE Chemoembolization is indicated in patients with liver-dominant hepatic malignancies who are not candidates for curative resection. In patients with hepatocellular carcinoma (HCC), TACE has been used as palliative treatment or as a bridge to liver transplantation. It is considered standard of care for intermediate stages of HCC according to the Barcelona Clinic …
Latest radiologic methods to treat liver cancer Current radiologic methods of treating hepatic malignancies Transarterial chemoembolization (TACE), transarterial embolization (TAE), selective internal radiation therapy (SIRT), percutaneous image-guided chemical ablation, percutaneous image-guided thermal ablation, TACE combined with ablation, and hepatic arterial chemotherapy infusion are the current radiologic methods. Hepatic arterial chemotherapy infusion has been used for …
How effective is Virtual Colonoscopy in screening for polyps Most studies suggest that the accuracy of CTC is greater than barium ememas and approaches optical colonoscopy, especially for polyps > 10 mm if the colon is properly prepped and distended. However, interpretation of CTC exams requires the review of both 2D and 3D images and …
