RAdiation SEgmentectomy With REsin Microspheres (RASEREM) Study

Radiation segmentectomy (RS) refers to selective infusion of Y-90 microspheres to the tumor bearing hepatic segment of hepatic artery. It was first described in 2011 and has been demonstrated to be a safe and reliable therapy able to deliver a curative intent high dose of selective ablative radiation for the treatment of hepatocellular carcinoma (HCC). This approach is gained to the radioembolization to a notable position in today's established algorithm for the multidisciplinary management of HCCs. 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.

In a recent retrospective study it is demonstrated that RS with resin microspheres are safe and effective In comparison to glass microspheres evet with lower radiation doses to the tumor. Despite this data on the effectiveness and safety of RS with resin microspheres in the multidisciplinary meeting I noticed that nuclear medicine specialist and interventional radiologist form our country rely on the use glass microspheres in the RS setting. As a nuclear medicine specialist who perform RS with resin microspheres I need to show the success of resin microspheres in RS with a multicenter prospective study. I believe that this multicenter experience would change clinical practice in our country and the scientific data that we will have would...
