Abstract

The use of rituximab brought attention to the hosts' immune system and to the microenvironment in non-Hodgkin's lymphoma cases. Our aim was to identify prognostic factors that can be measured easily to indicate the current state of the patient's immune status and possible reaction against malignant cells. In the retrospective analysis (2000-2008), 66 patients diagnosed with B-cell non-Hodgkin's lymphomas were enrolled (40 women, 26 men; mean age: 51 years). White blood cells, lymphocytes, CD3 +; CD4 +; CD8 + T-cells, immunoglobulin types A; G; M, anti-cardiolipin antibody isotypes A; G; M; and levels of beta-2-microglobulin were measured before the initiation of the first cycle of chemotherapy, during and after 4-weeks treatment. As for CD 3+ T-lymphocytes, the absolute CD 3+ T -lymphocyte numbers were higher before (0.78 × 10 9 /L) versus during (0.27 × 10 9 /L) treatment, and increased percentages were detected in pre- (66.57 %) and post-treatment (75.32 %). Absolute numbers of CD 8+ T-lymphocyte levels showed reduction before (0.26 × 10 9 /L) versus during (0.10 × 10 9 /L) therapy, but were elevated after (0.28 × 10 9 /L) treatment, while increased percentage before (21.99 %) versus after (29.85 %), and during (24.56 %) versus after (29.85 %) therapy were seen. Average white blood cell numbers were increased before (9.71 × 10 9 /L) versus during (12.07 × 10 9 /L) treatment, while decreased numbers could be observed, after (5.47 × 10 9 /L) treatment. IgA levels were decreased before (2.51 g/L) versus after (1.63 g/L) therapy. IgG levels were higher before (12.25 g/L) vs. after (8.64 g/L) treatment. IgM levels were decreased before (1.76 g/L) and after (0.83 g/L) as well as before (1.76 g/L) versus during (0.73 g/L) treatment. Anti-cardiolipin antibody type A level were decreased before (2.76 U/ml) versus after (2.49 U/ml) treatment. Decreased level of beta-2-microglobulin could be observed before (2.91 mg/L) versus post (2.28 mg/L) chemotherapy. Findings may provide better insight into the effects of immuno-chemotherapy on the hosts' immune system.
