Survival Analysis of 148 Patients with Primary Diffuse Large B Cell Lymphoma / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To investigate the clinical outcome of the patients with primary diffuse large B-cell lymphoma（DLBCL）.@*METHODS@#Clinical data of 148 patients with DLBCL in our hospital and cancer hospital from March 2006 to April 2016 were retrospectively analyzed. Kaplan-Meier analysis was used to estimate progression-free survival（PFS）and overall survival（OS）.@*RESULTS@#5-year OS and PFS rates were 85% and 69%，respectively. The survival analysis showed that 5-year OS rate of R-CHOP group was significantly higher than that of CHOP alone group（89% vs. 70%，P60 years），poor ECOG score（≥2），advanced stage（Ⅲ-Ⅳ），higher IPI score（≥3），CHOP alone and absence of radiotherapy related with poor survival rate. Furthermore，multivariate analysis showed that age>60 year significantly related with the worse OS.@*CONCLUSION@#Age >60 year is an important independent prognostic factor to predict worse OS or PFS.
