Using radiation therapy to treat liver metastases from colorectal cancer

Selective Internal Radiation Therapy With 90Y Resin Micropheres for Refractory Colorectal Cancer Liver Metastases - SIRT - A Translational Feasibility Study

Observational Aarhus University Hospital · NCT04491929

This study is testing how well Selective Internal Radiation Therapy works for patients with liver cancer that started from colorectal cancer by looking at changes in their blood before and after treatment.

What this trial studies

This observational study investigates the biological aspects of patients with liver metastases from colorectal cancer who are undergoing Selective Internal Radiation Therapy (SIRT). The study involves collecting and analyzing blood samples before and after treatment to quantify cell-free DNA and identify tumor-specific mutations. The aim is to understand the relationship between these biological markers and patient outcomes. Up to 30 patients will be included in this feasibility study conducted at Aarhus University Hospital.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with metastatic colorectal adenocarcinoma and liver-dominant disease that is not amenable to surgical resection or other local therapies.

Not a fit: Patients with detectable extrahepatic disease or those who have not met the pre-treatment criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the biological behavior of liver metastases and improve treatment strategies for colorectal cancer patients.

How similar studies have performed: While this approach is observational and focuses on biological analysis, similar studies using SIRT have shown promise in treating liver metastases, suggesting potential for success.
