Zach Berman (UC San Diego) and Tyler Sandow (Ochsner Health) join host Dr. Kavi Krishnasamy to walk us through real-world scenarios and share how they approach Y90 dose optimization. --- This podcast is supported by: Sirtexhttps://www.sirtex.com/ Medtronic Emprinthttps://www.medtronic.com/emprint --- SYNPOSIS First, the doctors review a case of HCC and discuss key lab values, like albumin, and their role in planning. They also break down how they manipulate variables like microsphere activity, perfusion density, and total dose to deliver a tumor dose of around 1,100 Gy. The doctors also challenge the standard perfused dose of 400 Gy for large tumors and share when they feel comfortable pushing beyond it. Next, they discuss nuances in treating portal vein tumor invasion and what decides which Vp classifications can be treated with Y90 or combination immunotherapy. A subsequent case involving a large central HCC tumor explores the risks of biliary stricture from high radiation and the challenge of missing tumor margins with overly selective catheterization. In the last case, the doctors discuss different scenarios in multifocal HCC liver lesions. Overall, the conversation explores different approaches based on tumor size, location, and patient liver function, and highlights the importance of multidisciplinary collaboration in optimizing patient outcomes. --- TIMESTAMPS 00:00 - Introduction and Case Overview01:28 - Patient Case Study - Hep C and Alcoholic Cirrhosis02:05 - Evaluating Liver Function and Treatment Approach04:50 - Tumor Dose and Perfusion Density15:49 - Portal Vein Tumor Invasion21:42 - Case Study: Large Central HCC Tumor Treatment22:19 - Challenges in Treating Large Central Tumors22:48 - Dosimetry Considerations and Biliary Strictures27:24 - Case Study: Assorted Multifocal HCC Lesions Scenarios
