Popis: Abstract Background The aim of the study was to explore the association between the SIRT1 single nucleotide polymorphism (SNP) rs3758391 and diffuse large B cell lymphoma (DLBCL) in a Chinese Han population. Methods 206 patients diagnosed with DLBCL and 219 healthy individuals were recruited in the present study. The genotyping of SIRT1 rs3758391 polymorphism was detected by polymerase chain reaction–restriction fragment length polymorphism. The SIRT1 mRNA expression was detected by the Taqman real-time quantitative PCR. Results Our study showed that the genotype TT and allele T frequency were significantly higher in DLBCL patients than that of controls (p = 0.02 and 0.01, respectively). No statistical differences were observed between SIRT1 rs3758391 and clinical characteristics of DLBCL patients. Analysis of the polymorphism revealed an increased risk of DLBCL associated with TC and TT genotype when compared with CC genotype [odds ratio = 2.621 and 3.518, respectively; 95% confidence interval (CI) 1.249–5.501 and 1.675–7.390, respectively; p = 0.011 and 0.001, respectively]. The survival analysis indicated that the patients with C allele had higher overall survival rate than those with genotype TT (p = 0.005). Furthermore, multivariate Cox regression analysis showed that the TT genotype of SIRT1 SNP rs3758391 was an independent poor prognostic factor for DLBCL patients (p = 0.006, HR 1.981, 95% CI 1.215–3.231). The SIRT1 mRNA expression was significantly upregulated in DLBCL patients than that of controls (p
