Abstract

Background and Purpose. The aim of this study is to determine the prognostic value of interim and final FDG-PET in major histotypes of B-cell NHL patients treated with rituximab containing-chemotherapy. Methods. We searched for articles published in English, limited to lymphoma, rituximab, and FDG-PET, and dedicated to deal with the impact on progression and survival. The log hazard ratios (HR) and their variances were estimated. Results. A PubMed and Scopus review of published trials identified 13 studies of Progression-free survival (PFS) and overall survival (OS) which were set as the main outcome measures. The combined HRs of I-PET for PFS and OS in DLBCL were 4.4 ( ) and 3.99 ( ), respectively. The combined HRs of F-PET for PFS and OS in DLBCL were 5.91 ( ) and 6.75 ( ), respectively. Regarding to non-DLBCL with F-PET, the combined HRs of F-PET for PFS and OS were 4.05 ( ) and 5.1 ( ), respectively. No publication bias existed. Conclusion. In DLBCL, both I-PET and F-PET can be performed for survival and progression analysis. But in other B-cell subtypes such as follicular lymphoma (FL) and mantle cell lymphoma (MCL), it would be necessary to perform F-PET for predictive purposes.
