Title: Lymphotoxin alfa and receptor-interacting protein kinase 1 gene polymorphisms may correlate with prognosis in patients with diffuse large B cell lymphoma treated with R-CHOP. Author: Chae YS, Kim JG, Sohn SK, Moon JH, Kim SN, Lee SJ, Park TI, Lee MH. Journal: Cancer Chemother Pharmacol; 2010 Feb; 65(3):571-7. PubMed ID: 19629486. Abstract: PURPOSE: Diffuse large B cell lymphoma (DLBCL) is a heterogenous disease entity due to diverse clinical outcomes to treatment. Most anticancer agents, regardless of their distinct mechanisms of action, ultimately kill cancer cells by inducing apoptosis. Accordingly, the present study analyzed the impact of polymorphisms of apoptosis-related genes on outcome in DLBCL patient treated with R-CHOP. PATIENTS AND METHODS: Ninety patients with DLBCL treated with R-CHOP were enrolled in the present study. The genomic DNA was extracted from paraffin-embedded tissue and 22 polymorphisms of 18 apoptosis-related genes were assessed using a polymerase chain reaction-restriction fragment length polymorphism assay. RESULTS: All the evaluable patients were responsive to R-CHOP. The multivariate analysis showed that the AA genotype of lymphotoxin alpha (LTA) C804A (rs1041981) and GG genotype of RIPK1 G83A (rs2272990) were significantly correlated with a worse time to progression (TTP) compared with the combined C/A and C/C genotype and the combined G/A and A/A genotype (hazard ratio [HR]=7.92; 95% confidence interval [CI]=1.42-44.18; P=0.018 and HR=20.02; 95% CI=1.59-251.52; P value=0.018, respectively), whereas no association was observed between the other polymorphisms and TTP. CONCLUSION: The polymorphisms of LTA (rs1041981) and RIPK1 (rs2272990) may correlate with TTP in patients with DLBCL treated with R-CHOP.[Abstract] [Full Text] [Related] [New Search]
