Overall survival analysis based on NK1R expression in pooled samples and different tumor grades. (a) Overall survival based on NK1R expression in pooled samples. (b) Overall survival based on NK1R expression in grade II tumors. (c) Overall survival based on NK1R expression in grade III tumors. Abbreviation: NK1R; neurokinin 1 receptor. Note: NK1R was not expressed in the investigated grade I tumors.
