Abstract

The impact of pharmacogenetics on predicting survival in diffuse large B-cell lymphoma (DLBCL) remains unclear. We tested 337 DLBCL patients treated with rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) for 9 single nucleotide polymorphisms from 6 genes (CD20FCGR2ANAD(P)H, ABCC2ABCG2 and CYP3A5). Patients who carried the NCF4 rs1883112 GG genotype showed significantly shorter progression-free survival (PFS) (P = 0.023) and event-free survival (EFS) (P < 0.001) comparing with A allele. A significantly shortened PFS (P = 0.013) and EFS (P = 0.002) was also observed in the patients with ABCG2 rs2231137 GG genotype. Furthermore, the elder (> 60 years old) or male patients with ABCG2 rs2231137 GG genotype had poorer PFS and EFS than A allele. Moreover, CD20 rs2070770 CC and RAC2 rs13058338 AT genotypes were independent predictors of chemotherapy-induced toxicity. Cox proportional hazards analyses demonstrated that the GG genotype of ABCG2 rs2231137 and NCF4 rs1883112 were risk factors in DLBCL patients. In conclusion, the identified polymorphisms provide guide for the identification of DLBCL patients who are likely to benefit from chemotherapy.
