Correlation Between Circulating Tumour Markers Early Variations and Clinical Response in First Line Treatment of Metastatic Colorectal Cancer

Not Applicable
Conditions
Circulating Markers
Metastatic Colorectal Cancer
Interventions
Procedure: Blood sampling for free mutant DNA analysis
Registration Number
NCT02872779
Lead Sponsor
University Hospital, Rouen
Brief Summary

The chemotherapy monitoring is currently based on radiological (RECIST 1.1 guideline) and clinical evaluation every 3 months. Circulating markers as Carcino Embryonic Antigen (CEA), circulating tumour DNA and total cell free DNA represent an alternative approach to evaluate the response. In the field of metastatic colorectal cancer (mCRC) recent studies suggest that early evaluation could be clinically relevant. Indeed, early tumoral response seems to be correlated to overall survival. Moreover, post-operative morbidity increases with the number of prior chemotherapy treatments. Early evaluation could allow to modify chemotherapy regimens when response appears to be insufficient.

The aim of the present study is to evaluate, in a prospective cohort of patients treated with systemic IV chemotherapy (5 Fluorouracil +/- oxaliplatin +/- irinotecan) +/- targeted therapy as first line treatment for a mCRC, the correlation between early variations of circulating tumour markers including CEA, circulating tumour DNA and total cell free DNA, and the 3 months objective response as defined in the RECIST 1.1 guideline.
