Résumé
The prognostic value of interim positron emission tomography (PET) interpreted according to visual criteria is a matter of debate in diffuse large B-cell lymphoma (DLBCL). Maximal standardized uptake value reduction (DeltaSUVmax) may better predict outcome. To compare the prognostic value of both methods, we analyzed PET done at baseline (PET0) and after 2 (PET2) and 4 (PET4) cycles in 85 patients with high-risk DLBCL enrolled on a prospective multicenter trial. All images were centrally reviewed and interpreted visually according to the International Harmonization Project criteria and by computing DeltaSUVmax between PET0 and PET2 (DeltaSUVmaxPET0-2) or PET4 (DeltaSUVmaxPET0-4). Optimal cutoff to predict progression or death was 66% for DeltaSUVmaxPET0-2 and 70% for DeltaSUVmaxPET0-4. Outcomes did not differ significantly whether PET2 and PET4 were visually positive or negative. Inversely, DeltaSUVmaxPET0-2 analysis (> 66% vs 70% vs
