Supplementary Table Legends Supplementary Table 1 Associations of,, γ, HIF1α, VEGF and GLUT1 expression with tumour status. In 212 breast carcinomas, high expression levels of,, γ, HIF1α, VEGF and GLUT1 were significantly associated with increments of primary tumour status (pt, p.2), nodal metastasis (pn, p.2) and stage (p.6). Supplementary Table 2 Associations between,, γ, HIF1α, VEGF and GLUT1 expression. expression was significantly positively correlated with expression of, γ, HIF1α, VEGF and GLUT1. Interestingly, the labelling indexes of all six of these markers are significantly and positively correlated to each other except for HIF1α and GLUT1, whose correlation is not significant. Supplementary Table 3,, γ, HIF1α, VEGF and GLUT1 expression significantly associated with patient survival outcome. Together with pt status, pn status, and stage,,, γ, HIF1α and VEGF expression significantly predicted disease-specific survival (DSS) and metastasis-free survival (MeFS) by Cox proportional hazards model. GLUT1 expression was significantly predictive for MeFS but not DSS. By log-rank analysis,,, γ and VEGF expression were significantly predictive for both DSS and MeFS, while HIF1α and GLUT1 were predictive for poorer MeFS but not DSS. Supplementary Table 4 Multivariate survival analyses. High expression of and and higher tumour stage remained prognostically significant for DSS (, p=.17;, p<.1) and MeFS (, p=.42;, p=.45).
