ABSTRACT
OBJECTIVE:
Pro-inflammatory and pro-angiogenic cytokines play an important role in the pathogenesis of lymphoma, and recent studies have shown that cytokines can be used as prognostic markers. Non-Hodgkin lymphoma (NHL) patients with high levels of serum interleukin-6 (s-IL6) and serum vascular endothelial growth factor (s-VEGF) have poor prognosis and shorter survival time. We aimed to determine pre-treatment levels of s-IL6 and s-VEGF and their relation with known prognostic markers, especially International Prognostic Index (IPI) scores, and to examine their effects on overall survival in newly diagnosed, untreated aggressive NHL patients. MATERIALS ANDMETHODS:
The study included 51 newly diagnosed NHL patients and 17 healthy controls. Blood samples were obtained to study s-IL6 and s-VEGF cytokine levels.RESULTS:
Patients with aggressive NHL diagnosis had higher s-VEGF and s-IL6 levels than the healthy population. If the s-IL6 levels of patients were above the cut-off levels, the overall survival time was shorter. There was no relation between s-VEGF and overall survival time.CONCLUSION:
s-IL6 is an independent prognostic factor that may be included in IPI risk classification. In addition to the s-IL6 level, age, erythrocyte sedimentation rate, beta-2 microglobulin, WHO performance status, and IPI score are independent prognostic factors that are effective, especially for overall survival, in the clinical follow-up of NHL patients.
