Objective To observe the serum levels of IL-6 and TNF-α in patients with multiple myeloma(MM),and explore the effects of thalidomide-combination chemotherapy on IL-6 and TNF-α.Methods The serum IL-6 and TNF-α in 79 MM patients and 30 normal controls were determined by ELISA,and the results of the patients in different stages as well as before and after therapy were compared.Results The concentrations of IL-6 and TNF-α in MM group were significantly higher than those in the control(t=8.117,11.525;P0.001).The levels of IL-6 and TNF-α in stage Ⅲ and stage Ⅱpatients were higher than those of stageⅠ(F=4.233,10.273;q=3.012-6.294;P0.05).Of 55 patients responding well to the therapy,levels of IL-6 and TNF-α declined significantly compared with before treatment(t=3.153,4.361;P0.01),for 22 patients who showed poor response to the therapy,the serum parameters did not reveal significant difference from that of before medication(t=0.850,0.913;P0.05).Conclusion The concentrations of IL-6 and TNF-α are high in MM patients,and associated with the clinical stages of the disease.The thalidomide-combined chemotherapy can significantly reduce the serum levels of IL-6 and TNF-α,a detection of this two items can be used as an auxiliary index in estimating the therapeutic efficacy and the condition of patients with MM.
