Published Data in Hepatocellular Carcinoma

Over 140 peer reviewed publications have assessed the use of SIR-Spheres® Y-90 resin microspheres for HCC.

In addition to the RCTs outlined on previous pages, other studies have demonstrated efficacy and safety of SIR-Spheres Y-90 resin microspheres for patients with HCC. One of these studies showed a significantly increased mOS, in the first-line setting, of 8 months compared with matched controls receiving active treatment or supportive care in patients with unresectable advanced HCC.1

A large retrospective multicentre analysis of SIR-Spheres Y-90 resin microspheres in HCC included first-line and second-line treatment in 325 patients with advanced HCC (ENRY trial).2 All patients received SIR-Spheres Y-90 resin microspheres, and the authors noted the following:

  • Survival outcomes compared favourably with transarterial chemoembolisation (TACE)/transarterial embolisation (TAE) for unresectable patients in Barcelona Clinic Liver Cancer (BCLC) stages A and B.
  • Benefits of SIR-Spheres Y-90 resin microspheres treatment were particularly favourable for patients with intermediate, BCLC stage B disease who were poor candidates for TACE or had failed TACE/TAE.
  • SIR-Spheres Y-90 resin microspheres also showed positive results in patients with advanced stage (BCLC stage C) disease, particularly those with portal vein thrombosis (PVT).

Importantly, OS benefits are suggested with first-line or second-line use of SIR-Spheres Y-90 resin microspheres, irrespective of patient age, presence or absence of PVT, and whether or not the patient has had a previous procedure.2-5

An additional benefit of SIR-Spheres Y-90 resin microspheres is down-staging HCC to potentially curative resection and bridging some patients to transplant.3,4,6,7 These effects can reduce the burden of the disease on the patient, and with down-staging to allow for subsequent curative treatment, the burden on the healthcare systems can be reduced in the longer term.
