The aim of this study is to determine the correlation of pretreatment fluorine-18 fluorodeoxyglucose uptake with clinicopathological factors and its prognostic value in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL).


A cohort of 162 patients with newly diagnosed DLBCL who had undergone pretreatment PET/computed tomography was retrospectively reviewed. The relationship of pretreatment maximum standard uptake value (SUVmax) with clinical factors, molecular markers, and efficacy was evaluated. The value of SUVmax in predicting progression-free survival (PFS) and overall survival was analyzed.


In all, 72.9% of the patients received R-CHOP treatment; the rest received CHOP chemotherapy. The median follow-up duration was 30 months (range, 4-124 months). The median SUVmax was 12.2 (range, 1.7-42.7). SUVmax between groups differed significantly with respect to each of International Prognostic Index (IPI) factors, except for age and performance status. High SUVmax was associated with high Ki-67 and Glut-3 protein expression, but not with Glut-1. Complete remission rate differed significantly between the low (SUVmax≤9.0) and the high SUVmax (SUVmax>9.0) groups (91.7 vs. 61.1%, P=0.000). Patients with low SUVmax showed favorable survival (3-year PFS: 92.2 vs. 63.6%, P=0.000; 3-year overall survival: 95.5 vs. 78.3%, P=0.003). On multivariate analyses, SUVmax predicted PFS independent of revised-IPI (SUVmax: P=0.011, hazard ratio 4.784; revised-IPI: P=0.004, hazard ratio 2.551).


Pretreatment SUVmax was associated with clinicopathological factors, efficacy, and survival outcome. A novel prognostic model on the basis of IPI score/pretreatment SUVmax might be useful for risk stratification of patients with newly diagnosed DLBCL Video abstract:
