Brief 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.

Condition or disease Intervention/treatment
Colorectal Cancer Metastatic Circulating Tumor DNA KRAS Gene Mutation NRAS Gene Mutation BRAF Gene Mutation Epidermal Growth Factor Receptor Inhibitor Other: Plasma circulating DNA analysis

Detailed 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

Clinical utility of ctDNA analysis for treatment decision

Use of ctDNA for KRAS, NRAS and BRAF testing prior to potential anti-EGFR monoclonal antibody treatment for metastatic colorectal cancer

Other: Plasma circulating DNA analysis
Clinical utility of ctDNA analysis for treatment decision

Primary Outcome Measures :
  1. Feasibility of ctDNA analysis for RAS mutation analysis [ Time Frame: maximum 7 days ]

    Feasibility measures

    Identification of wildtype or mutated status and results delivered to clinicians

    • Initial clinical test results i.e. ctDNA mutations or wildtype status within 7 days
    • Detailed mutation type characterization is provided retrospectively.

    Failure parameters

    • Quality of samples; PB > 5%, CPP1 major loss < 10%
    • Transportation > 3 week days
    • Analysis > 3 working days
    • Total results delivered > 7 days.

Secondary Outcome Measures :
  1. Retrospective concordance analysis [ Time Frame: By end of study, expected after 3 years ]
    Retrospective comparison of tumor mutation and plasma mutation analysis at baseline

  2. Disease control rate [ Time Frame: 1 year ]
    Rate of disease control

  3. OS [ Time Frame: 3 years ]
    Overall survival rate

  4. Resistance mutations [ Time Frame: At time of progression, data analysis expected after 3 years ]
    Rate of Ectoderm mutations at time of progression

  5. Lead time [ Time Frame: At time of progression, data analysis expected after 3 years ]
    Calcualted lead time between radiologically detected progression and molecular biologically detected ( by Ectoderm and other resistance mutations) in the ctDNA.
