This research registry studies Yttrium Y 90 resin microspheres in collecting data from patients with liver cancer not capable of being removed by surgery (unresectable) for the radiation-emitting Selective Internal Radiation-Spheres (SIR-spheres) in non-resectable (RESIN) liver tumor registry. The information generated will help doctors better understand treatment patterns involving Y90 therapy, gain additional insights in the long-term outcomes for patients, as well as guide future research for using Y90 therapy, especially for those conditions where data is currently very limited or lacking.
