• Non-Hodgkin's lymphoma
• Lactate dehydrogenase (LDH)
• beta 2-Microglobulin (beta 2-M)
• Cancer antigen 125 (CA 125)
• International prognostic index
• Survival analysis

We aimed to evaluate the prognostic value of the combination of three serum tumor markers (LDH, beta 2-M and CA 125) in patients with non-Hodgkin's lymphoma (NHL). Clinical and pathological variables including the levels of these markers were measured in 415 NHL patients. Statistical analysis showed that increased levels of all three markers were associated with stage, B symptoms, effusions, bone marrow involvement, and International Prognostic Index (IPI) in NHL patients (p<0.05). Overall survival and event-free survival rates were associated not only with LDH but also with beta 2-M and CA125 (p<0.001). Response to treatment and overall survival rates were different in three groups with elevated LDH; in particular, the combination of three or two elevated markers seemed to identify a group of patients at higher risk of treatment failure and/or relapse than the group with a high LDH level only. Furthermore, multiple Cox regression analysis showed that IPI score complemented by the additional serum markers beta 2-M and CA125 was a better prognosticator of overall and event-free survival than LDH alone. This result suggests that if the combination of three elevated serum tumor markers is included as a parameter in the IPI instead of LDH alone, the prognostic value of IN can be improved.
