Evaluation of therapeutic effect and prognostic value of 18F-FDG PET/CT in different treatment nodes of DLBCL patients

An analysis of the role of baseline, interim, and end-of-treatment ¹⁸F-FDG PET/CT in assessing DLBCL prognosis found that 3 to 4 cycles of R-CHOP treatment may be a time point for early prediction of early recurrence/refractory patients and active preemptive treatment. In terms of predicting recurrence, the combination of visual and semi-quantitative parameters showed higher positive predictive value and specificity than a single index.
