AbstractBACKGROUND: Improved treatment have modified survival outcome in patients with diffuse large B-cell lymphoma (DLBCL) and altered the importance of previously recognized prognostic markers. Design and methods: To evaluate International Prognostic Index (IPI) score before and after rituximab introduction and to validate the absolute lymphocyte count (ALC)/revised International Prognostic Index (R-IPI) model, we carried out a retrospective analysis on a total of 831 patients with DLBCL. RESULTS: Our results show that IPI lost its discriminating power with the introduction of rituximab. The analysis of our second set allowed us to validate the ALC/R-IPI model. The R-IPI and ALC/R-IPI could still be used for designing clinical trials, but both have difficulty recognizing a high percentage of poor prognosis patients, though it remains an important goal of a good prognostic model considering the modest impact of salvage treatments on survival. CONCLUSIONS: A new model on the basis of significant variables in the rituximab era and built on a large database of patients treated with rituximab is urgently needed. As prognostic models are changing with the efficacy and mechanisms of action of treatment utilized, looking for a new prognostic score is a never-ending story in which researchers are trying to hit a continuously moving target.
