Introduction. Non-Hodgkin lymphomas (NHL) represent a heterogeneous group of malignant lymphomas that develop from the malignant proliferation of the lymphatic tissue. Different prognostic scores (PS) are proposed to be used to determine NHL prognosis. The present study aims to estimate the utility of conventional PS for the determination of NHL overall survival (OS). Material and methods. 78 patients diagnosed with nodal NHL have been evaluated. International Prognostic Index (IPI), The combined index of hemoglobin, albumin, lymphocyte, and platelet (HALP), Platelet to Lymphocyte Ratio (PLR), Neutrophil to Lymphocyte Ratio (NLR), albumin/ globulin ratio(A/G), Charlson comorbidity index (CCI), were calculated as in the original references. Results. Out of the patients enrolled in the study, 67 developed B cell NHLs and 11 T cell NHLs. The mean age of the patients was 58(range 2283 years); The most frequent area of primary lymph node(ln) involvement was peripheral ln (84.61%), mediastinal ln (10.25%), and abdominal ln (5.12%); Aggressive NHLs were diagnosed in 73.07% of patients and indolent NHL in 26.93%; By using ROC analysis it was determined that the most sensitive score for determining OS was IPI (AUC=0.745), followed by HALP (AUC=0.652), PLR (AUC=0.625); NLR (AUC= 0.605); CCI (AUC=0.635); A/G (AUC=0.588). Conclusions. Among the evaluated prognostic tests, the IPI score and the HALP score proved to be the most sensitive results in the prognostication of the OS of NHL patients.
