Brief Summary

Adenocarcinoma of the colon and rectum is a common, serious disease and it is the second cause of death from cancer in Spain. The prognosis of CRC depends to a great extent on its stage when diagnosed. Patients with advanced disease, who present up to 40% of all patients, have a poor prognosis. Although the application of modern chemotherapy and radiotherapy treatments obtains median survival periods of around 24 months, the proportion of patients with advanced disease who obtain a cure is low. Systemic treatment of advanced CRC has changed considerably in the last ten years with the introduction of active drugs such as oxaliplatin, irinotecan, and capecitabine. The most commonly used first line regimens are 5-Fluorouracil-Leucovorin-Oxaliplatin (FOLFOX), Capecitabine-Oxaliplatin (XELOX), 5-Fluorouracil-Leucovorin-Irinotecan (FOLFIRI) and, to a lesser extent, Capecitabine-Irinotecan (XELIRI). Chemotherapy regimens are combined with different agents against therapeutic targets, three of which are effective in colon cancer: bevacizumab, which targets vascular endothelial growth factor (VEGF) and cetuximab or panitumumab, which target the epidermal growth factor receptor (EGFR). The use of cetuximab and panitumumab is not recommended in patients with KRAS mutations and the combination of a VEGF and EGFR agents is not beneficial. Two recent studies results have identified KRAS mutations as frequent drivers of acquired resistance to cetuximab and panitumumab in colorectal cancer patients. The conclusions indicate that the emergence of KRAS mutant clones can be detected non-invasively months before radiographic progression by a DNA Blood Test (Inostics´BEAMing Technology). Centro Integral Oncológico Clara Campal (CIOCC) is aiming to undertake a pioneer project aimed at integrating the analysis of KRAS switch status by BEAMing Technology in patients with metastatic colorectal cancer, tumor KRAS wild-type and BEAMing wild-type treated with first line FOLFIRI-cetuximab In naive chemotherapy tumor-KRAS wild-type metastatic colorectal cancer patients, who are BEAMing positive (KRAS mutated in blood) before treatment may have worse evolution in terms of PFS (progression Free Survival) and response rate than BEAMing negative (KRAS native in blood) patients. To know the proportion of patients who are BEAMing positive (KRAS mutation can be detected in circulating extracellular DNA) at the beginning of treatment, could be of great importance for treatment efficacy.

Outcome Measures

Primary Outcomes (1)

• To estimate the proportion of patients with advanced colorectal cancer in whom KRAS mutation can be detected in circulating extracellular DNA

  Baseline

Secondary Outcomes (7)

• To estimate the proportion of patients with metastatic colorectal cancer who switch from BEAMing negative to BEAMing positive while being treated with first line FOLFIRI-Cetuximab

  At 4 months and every eight weeks until disease progression up to 12 months

• To estimate the response rate, in biopsy-proven K-ras wild-type patients according to KRAS status in circulating extracellular DNA.

  Every eight weeks until disease progression up to 12 months

• Disease control rate according to KRAS status in circulating extracellular DNA.

  Every eight weeks until disease progression up to 12 months

• Complete response rate according to KRAS status in circulating extracellular DNA.

  Every eight weeks until disease progression up to 12 months

• Duration of response according to KRAS status in circulating extracellular DNA.

  Every eight weeks until disease progression, up to 12 months
