Selective Internal Radiation Therapy (SIRT) using SIR-Spheres® Y-90 resin microspheres is a targeted treatment option for liver tumours and has no effect on tumours outside the liver. Therefore, SIRT is only suitable for patients who have liver tumours where either the liver is the only site of disease or the liver is the major site of disease.
Before SIRT can be offered to you as a treatment option, there are a number of other factors that have to be considered by your doctor. Most importantly, you need to have a sufficiently healthy liver that is working satisfactorily. This is usually determined by a simple blood test.
