The International Prognostic Index (IPI) groups a series of prognostic factors that allow to predict the probable clinical evolution of non-Hodgkin's lymphomas (NHL). It was used in 121 patients with diagnosis of large-cell NHL. It was stratified into 2 age groups and these at the same time were divided into 4 Prognostic Groups (PG). In the Group A, where pàtients of all ages were included, the greatest number was found in the Low Prognostic Groups (LPG) and Low-Intermediate Prognostic Groups (LIPG) with 41.32 and 38.02 %, respectively. Complete Remission (CR) was attained in 47.1 %. The highest figures of remissions were observed in the LPG (54 %) and in the LIPG (52 %) The probability of Global Survival (GS) at 5 years was 60 %. The highest was obtained in the LPG (75 %) and in the LIPG (62 %). Group B included patients aged 60 or under. Most of them were in the LIPG (43.6 %) and in the High-Intermediate Prognostic Group (37.2 %). 50 % of CR was achieved in this group. The best therapeutic response was obtained in the High PG with 100 % of CR (but with only 2 patients), followed by the LPG with 69.2 %. GS at five years was 66 %. The highest was that of the LPG (90 %), followed by the ILPG (65 %). It was proved in a general way that better results are obtained in relation to CR and GS in the group analizing only patients under 60 and in the groups of good prognosis (LPG and LIPG).
