SLC2A1 and neoplasm: A few cases expressed GLUT1 and LDH differently among the considered compartments, but the concordance was still significant (p < 0.001); this was not observed for the comparison between the GLUT1 and the LDHA expression in the global cancer section and tumour stroma (where positivity was 9.2% for GLUT1 and 32.4% for LDHA) or the blood vessels (where positivity was 18.4% for GLUT1 and 65.2% for LDHA).
