In primary lesions, the GLUT1 IHC score was positively correlated with GLS (R=0.51, p=0.01), and CD36 was negatively correlated with GLS (R=-0.43, p=0.04) (Figures 4F, G), which represented the canonical characteristics of tumor cell metabolism in primary lesions. The gene discussed is SLC2A1; the disease is neoplasm.
