Résumé

Overall survival of metastatic colorectal cancer (mCRC) patients has been improved with the addition of targeted therapy such as anti-epithelial growth factor receptor monoclonal antibodies (anti-EGFR mAbs) to standard chemotherapy. Retrospective studies and randomized trials showed that the presence of RAS mutations was linked to the absence of clinical response to anti-EGFR mAbs. Patients harboring KRAS and NRAS mutations on exons 2, 3 or 4 have little or no benefit from anti-EGFR therapies. Polymerase chain reaction (PCR)-based assays are routinely used to assess KRAS and NRAS status, whereas deep sequencing with next generation sequencing (NGS) currently represents an alternative method.
