Registry for patients with unresectable liver tumors treated with SIR-Spheres

Observational Study to Assess Real-World Outcomes in Patients With Unresectable Liver Tumors Initiating Treatment With SIR-Spheres (Y-90 Resin Microspheres) (SIRtain Registry)

Observational Sirtex Medical · NCT05967143

This study is collecting information on how well SIR-Spheres treatment works for people with liver tumors that can't be removed and who haven't responded to chemotherapy.

What this trial studies

This observational registry aims to collect extensive data on the use of SIR-Spheres in patients with unresectable hepatocellular carcinoma (HCC) or liver metastases from colorectal cancer (mCRC) who are refractory to or intolerant to chemotherapy. The study will involve approximately 845 patients across 44 sites in 10 countries, assessing real-world clinical responses to SIRT with SIR-Spheres. The goal is to validate the safety and effectiveness of this treatment in routine clinical practice.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with unresectable HCC or liver metastases from mCRC who are suitable for SIR-Spheres treatment.

Not a fit: Patients who have previously received radiation treatment to the liver or are participating in other interventional clinical trials may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the effectiveness of SIR-Spheres for patients with difficult-to-treat liver tumors.

How similar studies have performed: While this approach is observational, similar studies using SIR-Spheres have shown promising results in treating liver tumors.
