[Research progress on 18F-FDG PET/CT in evaluating prognosis of patient with diffuse large B cell lymphoma].

Diffuse large B cell lymphoma (DLBCL) is one of the most common pathological type of non Hodgkin's lymphoma in adult, with a high mortality and a variety of prognostic factors. (18)F-FDG PET/CT, a functional imaging modality used for staging and monitoring response of a variety of human neoplasia to treatment, has a higher sensitivity and specificity than conventional anatomical imaging. Patinets taking (18)F-FDG PET/CT scanning for DLBCL before treatment and after complete standard treatment of DLBCL patients not only contributes to the clinical accurate staging, but also has a certain value in evaluating the prognosis of DLBCL patients and monitoring of recurrence. However, the value of interim PET/CT for evaluation of prognosis remains controversial. Therefore, this review focuses on the research progress of (18)F-FDG PET/CT for evaluating prognosis of patient with DLBCL, including baseline, interim and post-treatment (18)F-FDG PET/CT.
