LDHA and hepatocellular carcinoma: To investigate whether preoperative hyperglycolysis can be predicted by imaging, we immunostained HCC samples resected from patients who underwent 18F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET/CT), and FDG-PET hyperaccumulation significantly correlated with increased LDHA expression and enhanced Treg cell recruitment (p = 0.006 and 0.039, respectively) shown in Table S4.
