Abstract

Multiple myeloma is a disseminated malignancy of monoclonal plasma cells that accounts for 15 % of all hematological cancers. The present study was conducted to evaluate the role of inflammation and oxidant-antioxidant dynamics in the etiology of this disease. The study population comprised of 20 cases of multiple myeloma and 20 healthy controls. The parameters evaluated were serum malondialdehyde (MDA), superoxide dismutase (SOD) and ferritin levels. The serum MDA levels were 1.9 ± 0.96 nmol/ml in cases as compared to 0.98 ± 0.55 nmol/ml in the controls. Similarly, a statistically significant difference was noted in the SOD and ferritin levels between the cases and controls (93.2 ± 23.8 vs. 210.1 ± 190.5 U/ml and 285.8 ± 216.4 vs. 131.8 ± 30.1 ng/ml respectively). Our study highlights the imbalance in the oxidant-anti oxidant mechanism and the role of smoldering inflammation in the etiology of multiple myeloma.
