Abstract 2476


The purpose of this study was to develop a newly accepted prognostic nomogram to estimate overall survival (OS) in patients with diffuse large B-cell lymphoma (DLBCL) and assess its incremental value to the traditional International Prognostic Index (IPI) and NCCN-IPI for individual OS estimation.


The clinical data from 1,118 patients with DLBCL treated at Cancer Hospital Chinese Academy of Medical Sciences between 2006 and 2012 were reviewed. A nomogram was developed that predicted OS based on the Cox proportional hazards model. To contrast the utility of the nomogram against the widely used IPI and NCCN-IPI, we used the concordance index (C-index) and a calibration curve to determine its predictive and discriminatory capacity.


The 5-year OS rate was 64.1% for the entire group. The entire group were divided into the primary (n = 783) and validation (n = 335) cohorts. The nomogram included eight important variables based on a multivariate analysis of the primary cohort: Ann Arbor stage; age; ECOG PS; LDH; β2-MG; CD5; Bcl-6 and Ki-67 index. The calibration curve showed that the nomogram was able to predict 5-year OS accurately. The C-index of the nomogram for OS prediction was 0.77 in the primary cohort and 0.76 in the validation, which was superior to the predictive power (range, 0.71-0.74) of the IPI and NCCN-IPI in the primary and validation cohorts. To detect the accuracy of the nomogram for rituximab plus CHOP (R-CHOP) like regimen, we took subgroup analysis. The C-index of the nomogram for OS prediction was 0.78 in the R-CHOP like regimen subgroup, and 0.76 in the CHOP like regimen subgroup.Table:

The proposed nomogram provides an individualized risk estimate of OS in patients with DLBCL, especially for the patient who received R-CHOP like regimen.
