Interim 18F-FDG PET/CT and BCL2 for predicting the prognosis of patients with diffuse large B-cell lymphoma in the rituximab era

In this study, we investigated the prognostic role of interim fluorine-18-fluorodeoxyglucose PET/computed tomography (I-PET/CT) and BCL2 in diffuse large B-cell lymphoma (DLBCL) patients treated with rituximab-containing chemotherapy. Materials and methods A total of 106 patients with newly diagnosed DLBCL underwent PET/CT scans at baseline and a subsequent I-PET/CT after the fourth cycle of chemotherapy. I-PET/CT was analyzed using the Deauville five-point score. The prognostic significance of I-PET/CT and BCL2 was evaluated by predicting progression-free survival (PFS) and overall survival (OS). Results With a median follow-up of 25 months, the 2-year PFS and OS were 78 and 95% in the I-PET/CT-negative group and 33 and 57% in the I-PET/CT-positive group (P
