PTLD-negative and non-destructive PTLD cases
In this cohort study, 19 patients were PTLD-negative cases and 47 patients were diagnosed with non-destructive PTLD by biopsy.TABLE 2 shows the clinical baseline characteristics of the two groups. There were no significant differences between the two groups in terms of age at surgery, gender, diagnosis, donor type, EBV status of the tumor, time between transplant and 18F-FDG PET/CT, the longest diameter of the lymph node at the biopsy site (LDL), and SUVmaxTon (P > 0.05). In contrast, there were significant differences in the shortest diameter of the lymph node at the biopsy site (SDL), SDL/LDL, SUVmaxBio, SUVmaxBio/SUVmaxTon, and (SDL/LDL)*(SUVmaxBio/SUVmaxTon) between the groups (P < 0.05).
