High expression of Caprin-1 was correlated with high glycolytic activity based on metabolic parameters in 18F-FDG PET imaging. A Representative images of PET/CT imaging and immunohistochemical staining for Caprin-1 in ESCC patients with high SUVmax (left) and low SUVmax (right). B The TLG, MTV C, SUVmax D, and SUVmean E showed a linear correlation with the protein levels of Caprin-1 with correlation coefficients of 0.390, 0.216, 0.538, and 0.540 respectively. F The determination of the cutoff value of SUVmax, SUVmean, TLG, and MTV by the receiver operating characteristics (ROC) curve
