Abstract

Objective: To explore the prognostic significance of inflammatory indicator, neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR), for advanced-stage diffuse large B-cell lymphoma (DLBCL). Methods: The data of advanced stage DLBCL cases was retrospectively collected, and all the patients were seen from January 2006 to December 2012 in National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences. The patients were divided into the low NLR group (≤5:1) and the high NLR group (>5:1); the low PLR group (≤300:1) and the high PLR group (>300:1). Kaplan-Meier method was used to compare the survival rates between groups, multivriate Cox proportional hazard regression analysis was performed to assess the independent prognostic significance of clinical and histopathological variables on events or OS. Results: A total of 361 patients were included in the study. Under a median follow-up of 89 months, the 5-year overall survival (OS) and progression-free survival (PFS) of the whole group were 42.9% and 31.3%, respectively. The 5-year OS rate and PFS rate were 48.2% and 35.1% in the low NLR group, which were 24.1% and 17.7% in the high NLR group, respectively. The 5-year OS rates and PFS rate were 45.4% and 33.2% in the low PLR group, which were 29.8% and 21.1% in the high PLR group (all P<0.05). Univariate analysis showed that NLR >5∶1, PLR >300:1, age>60 year, ECOG PS>1 score, stage IV, B symptom, bulky disease, number of extranodal sites >1, Ki-67index >90%, LDH elevated and β2-MG elevated had significant influence on prognosis(all P<0.05). Multivariate analysis demonstrated that NLR, stage, B symptom, bulky disease, ECOG PS score, Ki-67 index and β2-MG were associated with poor prognosis in the advanced-stage DLBCL.
