摘要: It is now well established that metastatic colorectal cancer patients without KRAS mutation (codon 12) benefit from treatment with an epidermal growth factor receptor monoclonal antibody (anti-EGFR mAb). Recently, EFGR and mutations have been shown to exist in who developed resistance anti-EGFR mAb. We analyzed KRAS, BRAF V600E EGFR S492R 37 post-anti-EGFR mAb tumor samples 23 treated chemotherapy plus No EGFRS492R was detected. A found after only one tumor. Our results suggest acquired do not constitute the main mechanism of combination chemotherapy.
