Abstract

MitochondrialDNA(mtDNA) copy number is increased in patients with chronic lymphocytic leukemia (CLL), in Burkitt lymphoma andEpstein-Barr virus-transformed lymphoblastoid cell lines, and in T cells activated via the T-cell receptor.We hypothesized that having a higher mtDNA copy number in peripheral white blood cellDNAfrom healthy subjects would be associated with future risk of non-Hodgkin lymphoma (NHL). We analyzed mtDNA copy number in 104 incident male NHL cases and 104 matched controls within the prospective Alpha-Tocopherol, Beta-Carotene (ATBC) Cancer Prevention cohort. There was a doseresponse relationship between tertiles of mtDNA copy number and risk of NHL (odds ratio [OR], 95% confidence interval [CI]: 1.0; 1.4 [0.7-2.8]; and 2.4 [1.0-5.5], respectively; Ptrend = .046). The effect was most pronounced for the CLL/small lymphocytic lymphoma (SLL) subtype (OR: 1.0; 3.2 [0.7-15.7]; 14.1 [1.9-103.2]; Ptrend = .009). These results suggest that mtDNA copy number could be associated with the risk of NHL, particularly CLL/ SLL.
