Diffuse Large B-Cell Lymphomas (DLBCL) correspond to 50% of non-Hodgkin's lymphomas. Since 1993 the treatment of these patients has been directed by the International Prognostic Index (IPI), validated in several studies. However, the use of the IPI has not been evaluated in our population and social-economical conditions. In this study, we evaluate the impact of the age-adapted IPI (aIPI) in the complete response, overall survival and disease-free survival in under 60-year-old DLBCL sufferers treated in the Hematology Service of HCFMUSP. Of the 111 evaluated patients, 60 were classified as aIPI low and intermediate risk and 51 as aIPI intermediate-high and high risk. The patients with low and intermediate risk were analyzed as a whole with adapted low risk and patients with intermediate-high and high risk with the adapted high risk. We verified that the overall survival and disease-free survival were influenced by the clinic stage, LDH value and patients performance status. We recommend the regular use of IPI in the treatment of the patients with DLBCL in our institution.
