Low-dose Y90 Treatment Planning for HCC

Status Completed

Clinical Trial Summary

The study proposes low-dose Y90 microspheres for therapy planning of HCC, as an alternative to Technetium (99mTc) albumin aggregated (MAA), to be a bioidentical therapeutic Y90 surrogate marker to better predict and thus achieve optimal therapeutic dosing.

Clinical Trial Description

Hepatocellular carcinoma is a second deadliest cancer in the world with less than 20% of patients eligible for curative surgery at the time of diagnosis. Yttrium-90 (Y90) radioembolization is palliative treatment with promising result. However, one of the most important factors in the success of Y90 treatment is to ensure adequate dose of radioactive material is delivered to the tumor. The technetium-99 macroaggregated albumin (MAA) which is currently used for Y90 treatment planning and shunt study does not predict distribution of Y90 in the lungs, tumors, and liver. Therefore, accurate and personalized treatment planning cannot be performed using MAA. In this study, we are proposing using low-dose Y90 microspheres for the planning stage of the therapy to obtain an accurate estimation of distribution of Y90 therapy dose. This will in turn allow us to ensure adequate dose of Y90 is delivered to the tumor(s) while minimizing dose delivered to non-tumor liver and lungs in order to decrease the chance of treatment related toxicity to the liver and lungs. ;
