Expression of epidermal growth factor receptor (EGER) may be of prognostic value in renal cell cancer (RCC). Gene amplification of EGER was investigated in a cohort of 315 patients with advanced RCC from a previously reported randomised study. Using fluorescent in situ hybridisation, only 2 patients (0.6%) had gene amplification; therefore gene amplification is of no prognostic value in RCC.
