ABSTRACT
Radioembolization of inoperable primary or metastatic liver cancers with Yttrium-90 (Y-90) labeled radiomicrospheres is a treatment modality with its efficacy established. It is possible to administer curative doses of radiation to the tumor tissue while preserving normal liver parenchyma to a large extent with selective intraarterial radionuclide therapy performed with Y-90 labeled microspheres. Selective intraarterial radionuclide therapy with SIRSpheres ® was approved by Turkish Ministry of Health for the treatment of inoperable liver cancers in April 2008. In this study, the results of selective intraarterial radionuclide therapy performed with SIR-Spheres® for the first time in Turkey in a 32-year-old male patient with inoperable liver metastasis due to medullary thyroid carcinoma are presented.
