Abstract: The combination of chemotherapy with antiepidermal growth factor receptor antibodies such as cetuximab and panitumumab which prolong the survival time in the past few years have been  widely adopted for the treatment of metastatic colorectal cancer. However, a large number of patients develop resistance to these agents, while there is no standard treatment after acquired resistance yet. Therefore, finding out the mechanisms of acquired drug resistance and putting forward reasonable methods to overcome the acquired resistance will be improve its curative effect.
