Mode of Action



SIR-Spheres®Y-90 resin microspheres

  • are directly targeting liver tumours via the hepatic artery
  • minimise exposure to the remaining healthy liver tissue

Due to their relatively low density of 1.1 g/mL, SIR-Spheres Y-90 resin microspheres

  • travel with the blood stream
  • are taken deep into the tumour microvasculature where they become lodged.

SIR-Spheres Y-90 resin microspheres can therefore be delivered in a slow deliberate manner

  • to achieve an even distribution
  • to maximize the number of microspheres delivered,
  • to optimize tumour coverage - even in patients with extensive disease.
