3 HCC patients

For your patients with unresectable hepatocellular carcinoma Personalised and versatile TheraSphereTM Y90 Therapy


Deliver better long-term outcomes with effective downstaging or bridging treatment1

Patient on wheelschair

TheraSphere Y90 Therapy not only provides you and your patients with time to bridge to future treatments, but can allow downstaging of the tumour to access curative surgery options.

Extend mOS to 12.5 years post liver transplant*1

Treatment-naïve patients with unresectable HCC
