Experimental Note Identified from the Human Clinical Data
In Vivo Model A retrospective survey in conducting clinical studies Homo sapiens
Experiment for
Molecule Alteration		 Ligation assay; BEAMing assay
Experiment for
Drug Resistance		 Progression-free survival analysis; Overall survival analysis
Mechanism Description Our study indicates that the resistance mutations in kRAS and other genes were highly likely to be present in a clo.l subpopulation within the tumors prior to the initiation of panitumumab therapy.

Drug Resistance		 Progression-free survival (PFS) analysis; Overall survival (OS) analysis
Mechanism Description Cetuximab and panitumumab are monoclonal antibodies (mAbs) against epidermal growth factor receptor (EGFR) that are effective agents for metastatic colorectal cancer (mCRC). The mechanisms of resistance refer to intrinsic and extrinsic alterations of tumours. The intrinsic mechanisms include EGFR ligand overexpression, EGFR alteration, RAS/RAF/PI3K gene mutations, ERBB2/MET/IGF-1R activation, metabolic remodelling, microsatellite instability and autophagy. Extrinsic alterations mainly disrupt the tumour microenvironment, specifically immune cells, cancer-associated fibroblasts (CAFs) and angiogenesis.
