Abstract:
Objective To detect the level of Tnl and T.2 type cytokines in the patients with lym-phoma in order to find out the laboratory evidence of tumor immunotherapy. Methods The levels of serum IFN-γ, TNF-α, IL-2, IL-4, IL-5 and IL-10 were measured by cytometric bead array (CBA) in 92 patients with lymphoma, and 70 normal sera as control. Results The levels of TH1 type cytokincs in 92 patients with lymphoma were: IFN-γ (34.26 ± 33.48) pg/ml, TNF-α (8.17 ± 10. 09) pg/ml, IL-2 (3.74 ±1.72) pg/ml; and the levels of TH2 type cytokines were: IL-10 (6. 28±8.56) pg/ml, IL-5 (3.53 ±3.20) pg/ml, IL-4 (6.22±7.13) pg/ml. The levels of TH1 and TH2 cytokines in lymphoma patients were significantly higher than those in controls(P ＜ 0.01) except TNF-α. And the rate of IL-2/IL-4 was signifi-cantly decreased in lymphoma patients(P ＜0.01). The level of IL-10 in Ⅲ/Ⅳ stage lymphoma patients was much higher than that in Ⅰ/Ⅱ stage patients(P ＜0.01). The level of IFN-γ/was significantly decreased in aged patients with lymphoma (P ＜0. 05). Conclusion TH 1/TH2 is imbalance in lymphoma, which may provide clinical index for the evaluation of progrossien and prognosis. In the lymphoma patients TH1/TH2 shifts to TH2, which may be the mechanism of tumor arising and transferring by immune escape from immu-nosurveillance.
