摘要: Several studies have shown that mutation profiles could influence the treatment decisions in patients with metastatic colorectal cancer (mCRC). It has been proven mutations exon 2 of KRAS ongogene gain no benefit from monoclonal antibodies (moAbs) against Epidermal Growth Factor Receptor (EGFR), cetuximab and panitumumab. Currently, determination mutational status represents a paradigm for biomarkers development era molecular targeted therapies. The current manuscript is an overview, which summarizes critically reviews clinical relevance proposed mechanism resistance to beyond mutations, such as: outside codon 12 13, NRAS, BRAF V600E, PIK3CA 9 20 PTEN loss, EGFR ligands AREG, EREG mRNA expression amplification. aim identify markers might be used select higher probability response anti-EGFR moAbs. Overall, accumulating evidence biology CRC has, substantially, changed approach mCRC given clinicians more rational options treating this illness.
