Figure 5 showed a representative patient with a TMIT-I tumor exhibited hypermetabolic tumors on DTP PET, characterized by high expression of PD-L1 and high density of PD-1, CD8+ TILs. Of the nine metabolic features above, eSUVmax, eSUVmean, eTLG, dSUVmax and ΔTLG were selected in the LASSO model with 10-fold cross-validation (Figure 6). The gene discussed is PDCD1; the disease is neoplasm.
