Brief Summary
Radiation segmentectomy (RS) refers to selective infusion of Y-90 microspheres to the tumor bearing hepatic segment of hepatic artery. Majority of the data on RS is based on the Glass microspheres experience. Due to different properties of Resin and Glass microspheres description of dose limits to the segment for effectiveness of treatments with Resin microspheres are needed. Based on this background in this study it is aimed to evaluate the safety and efficacy of RS with resin microspheres in HCC patients. Secondly, it is planned to describe the dose limits for complete radiological response.
