Homogeneity in stage classifications using the 7th and 8th AJCC/UICC staging systems and the modified pTNM staging system for both the training and external validation cohorts. ac Stages IIIA, IIIB, and IIIC classified according to the 7th edition, respectively; df stages IIIA, IIIB, and IIIC classified according to the 8th edition, respectively; gi stages IIIA, IIIB, and IIIC classified according to the modified pTNM staging system, respectively. jl Stages IIIA, IIIB, and IIIC classified according to the 7th edition, respectively; mo stage IIIA, IIIB, and IIIC classified according to the 8th edition, respectively; pr stage IIIA, IIIB, and IIIC classified according to the modified pTNM staging system, respectively. The homogeneity of the proposed modified pTNM staging system is higher, supporting by mild differences in survival curves, than those of the 7th and 8th AJCC/UICC staging systems
