Brief Summary

Observational, feasibility study investigating biological aspects in patients with liver metastasis from colorectal cancer undergoing treatment with SIRT, by translational analysis of biological samples.

Detailed Description

In this study, the investigators seek to investigate biological aspects in patients with colorectal cancer liver metastasis undergoing treatment with Selective Internal Radiation Therapy, by translational analysis of biological samples.

SIRT will be conducted as per standard procedure at Aarhus University Hospital. Translational blood samples will be drawn pre-treatment and during follow up.

The total cell free DNA level will be quantified in all samples. The samples will be analysed for tumour specific mutations such as the KRAS, BRAF and NRAS oncogenes.

The investigators expect to include up to 30 patients.

This is a purely observational translational study. Results will be analysed in relation to outcome data.

The study is conducted in collaboration with:

Department of Gastroenterology and Hepatology, Aarhus University Hospital Department of Radiology, Aarhus University Hospital Department of Nuclear Medicine, Aarhus University Hospital

Conditions

Liver Metastasis Colon Cancer
