Peripheral blood lymphocyte/monocyte ratio predicts outcome in follicular lymphoma and in diffuse large B-cell lymphoma patients in the rituximab era.

Abstract

Diffuse large B-cell lymphoma is an aggressive lymphoma and a large number of studies have therefore focused on the search for prognostic factors. The same interest concerns FL, for which identification of patients candidates for watch and wait (W&W) strategy is still an option. Studies about the number and type of lymphocytes and monocytes detectable in patients with Hodgkin and non-Hodgkin lymphomas indicate they might affect the pathogenesis and prognosis of these diseases. LMR is recently under investigation as a new prognostic parameter in DLBCL; the role of this ratio in FL in the rituximab era is unknown.
