Clinical trials

Renal cell carcinoma (RCC), the most common type of kidney cancer, is typically treated with surgery; however, there is no established therapy for patients who are not surgical candidates and who have tumours greater than 4.0 cm in size. Selective internal radiation therapy (SIRT) or radioembolization using radioactive spheres containing 90-Yttrium (Y-90) is successful at treating large tumours with high doses of radiation within the liver and might be similarly effective for treating larger RCC tumours in patients, particularly those who are not surgical candidates. This prospective study will enroll 16 participants with RCC who are not candidates for surgery and treat them with Y-90 radioembolization using a high-dose therapy to see if it is an effective cancer therapy. Primary outcome will be RCC treatment response 1 year after the Y-90 radioembolization. Additionally, the safety, tolerability, and impact on kidney function of the therapy will be monitored for all participants. Patients will be followed for a total of 5 years to evaluate long-term outcome in cancer control and safety of the treatment.
