Clinical Trial Summary

The present study will investigate the feasibility and clinical value of using circulating tumor DNA as selection for anti-epidermal growth factor receptor treatment for metastatic colorectal cancer.

Description:

The primary aim of this prospective study is to investigate if cfDNA in plasma is feasible and reliable for selection of mCRC patients who will benefit of anti-EGFR monoclonal antibody therapy Secondary, to analyze developments in mutational status as reflected by cfDNA in plasma during therapy and at time of progression
