Abstract
Follicular lymphoma is an indolent lymphoma with potential relapses in the course of its evolution. In the last few years, new therapeutic strategies have improved patient´s survival. However, a high risk subgroup progresses early with a shorter overall
survival. Our primary objective is to report the incidence of POD24 and its impact on OS and, as a secondary objective, to evaluate the association of the FLIPI 1, FLIPI 2 and PRIMA PI scores and the clinical-metabolic variables with the risk of a POD24
event. Three hundred and thirty-two patients were included, 46 patients (13.8%) with a POD24 event.
Factors independently associated with greater probability of a POD24 event were: presence of B symptoms (OR 2.09) and elevated LDH (OR 1.27). In
this study we report a significant difference in OS between POD24 vs NO POD24 (at 60 months, 63 vs 95% with p <0.001) reinforcing the POD24 impact as a negative prognostic factor. Despite being a retrospective study and the limited number of patients, we report local data not available to date. New clinical and/or biological markers will be necessary to identify the subgroup with POD24 risk, which could benefit from an adapted therapy.
