Diffuse Large B Cell Lymphoma (DLBCL) is the most common NHL and %80 of all NHLs. Although it has some subtypes with heterogenous characteristic for prognosis, in area of rituximab monoclonal anti-body, improvement in overall survival (OS) was achieved. We evaluated response of treatment, epidemiologic features, OS and progression-free survival (PFS) of our patients with DLBCL for 5-years retrospectively.

Materials and Methods:

We investigated 160 patients from three centers in Turkey. Demografic features, stages, risk groups, the type of first-line therapy and its reason, duration of remission, relapse status and adverse events were collected. Package for the Social Sciences (SPSS) 22.0 program were used for statistical analysis. Dates of survival and significancies were obtained by Kaplan-Meier analysis and long-rank test, respectively. Analyses with p values below 0.05 were recognized as statistically significant.


Mean age of patients at the time of diagnoses was 60.75 ± 13.95. Number of patients with only nodal involved and extranodal involved were 109 (%68,1) and 51 (%31,9), respectively. Frequency of relaps after the first therapy was significancy superior in males than females. Althought there was no significant differencies between stage and OS, and response to treatment (p=0,140 ve p=0,378), significant difference was obtained between stage and PFS (p=0,038). In additon there wasn’t significant differencies between OS and PFS among patients with nodal and extranodal involved. Otherwise patients with advance age adjuested international prognostic index (aaIPI) scores had significancy inferior rate of response of first treatment (p=0,031).


We demosrated the characteristics of patients with DLBCL as a general population and other else results related risk factors were similary with literatures.
