PDGFRB and neoplasm: Thus, this research aimed to screen different tumor types for human epidermal growth factor receptor 2 (HER-2), epidermal growth factor receptors 1 (EGFR1), vascular endothelial growth factor receptor 2 (VEGFR-2), platelet derived growth factor receptor beta (PDGFR-β), c-KIT, and extracellular signal-regulated kinase 1/2 (ERK1/ERK2) immunoexpression to propose a panel of antibodies predictive for the use of TKI drugs.
