Immunohistochemical analysis for hepatocyte growth factor, c-Met, phosphorylated c-Met, phosphorylated AKT, phosphorylated MEK, epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), p53 and vimentin was performed on an ASPS tissue microarray, yielding complete data from 26 tumours. Activation of c-Met and its downstream effectors was noted, whereas only limited EGFR expression was seen. VEGF was expressed to varying degrees. Only one sample exhibited strong nuclear p53 expression, while 10 expressed low levels. Vimentin expression was negative in the vast majority of samples (96%).
