Several studies indicate RTKs are associated with MPM tumor progression, including epidermal growth factor receptor (EGFR) (Pache et al., 1998), vascular endothelial growth factor receptor (VEGFR) (Ohta et al., 1999; Strizzi et al., 2001), insulin growth factor 1 receptor (IGF1R) (Lee et al., 1993; Pass et al., 2004), and AXL (Ou et al., 2011). The gene discussed is EGFR; the disease is neoplasm.
