Abstract:
The study was aimed to investigate the clinical efficacy and adverse reactions of different thalidomide regimens in the treatment of multiple myeloma (MM), and to explore the relationship between efficacy of thalidomide and serum level of TNF-alpha in MM patients. The 85 patients with MM were divided into 5 groups according to different combinations of thalidomide. These 5 groups were following: group with the high dose (HD-T), group with thalidomide+VAD chemotherapy (T-VAD), group with thalidomide+MP chemotherapy (T-MP), group with thalidomide plus dexamethasone (TD), and group with low dose of thalidomide (LD-T). Except 5 groups mentioned above, the group with conventional VAD chemotherapy was served as the control. Clinical effects, adverse reactions, treatment-related mortality were observed. At the same time, serum levels of TNF-alpha in 30 cases of MM treated with thalidomide (15 cases effective and 15 cases ineffective) before and after treatment were detected by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) and were compared with the clinical efficacy. The results showed that the efficient rate of HD-T, T-VAD, T-MP, TD, LD-T groups were 25.0%, 80.0%, 71.4%, 33.3%, 27.3% respectively; the efficacy of T-VAD, T-MP groups were significantly higher (p<0.05) than that of other groups and conventional VAD chemotherapy group. The incidence of significant adverse reactions (peripheral neuropathy, fatigue, abdominal distension and constipation, rash, edema, leukocyte and platelet decrease) in 5 groups were 75.0%, 30.0%, 28.6%, 14.3%, 9.1% respectively, no IV grade toxicity and deep vein thrombosis were found. The treatment-related mortality was 0%. At the same time, it was found that the serum levels of TNF-alpha in ineffective group treated with thalidomide were 44.7+/-5.7 pg/ml and 46.3+/-4.0 pg/ml before and after thalidomide treatment, and there was no significant difference (p>0.05). The serum levels of TNF-alpha (27.3+/-6.4) pg/ml in the effective group after treatment was significantly lower than that before treatment (49.2+/-7.3) pg/ml (p<0.05). It is concluded that compared with conventional chemotherapy, thalidomide is a effective drug for treating MM patients. Thalidomide in combination with chemotherapy (T-VAD, T-MP) may be one better therapeutic regimen with high efficiency and milder adverse reactions. Serum level of TNF-alpha is an indicator for finding effects of thalidomide, and plays a role in the pathogenesis of MM.
