Show Notes

We continue the conversation where we left off in Part 1. Tyler and Juan share their thoughts on lobar treatment vs. radiation segmentectomy, selection strategies, and their preferred combination of ablation and Y-90. Tyler also reviews the core tenets of Y-90 treatment and references a handful of major landmark trials and studies.

Juan highlights more studies that guide their approach to preoperative mapping and intraoperative delivery of Y-90. Juan emphasizes cone-beam CT and how this technique has significantly evolved over the years. We cover dosimetry software, navigation software, and the calculation of treated tumor volumes. Additionally, Tyler and Juan discuss their change in treatment approach for especially complex cases, which can involve factors such as extrahepatic feeders and difficult treatment locations. We also discuss the redistribution of flow and how underlying liver disease may affect treatment plans.

We wrap up Part 2 of our discussion by highlighting the doctors’ current research pursuits. Tyler tells us about exciting new developments in the tumor marker arena, the emerging role of albumin in HCC, and the rising popularity of radiation segmentectomy in metastatic disease. Juan shares a few closing thoughts on the extrahepatic applications of Y-90 and the advantages of using AI in interventional radiology.
