Graphic abstract

Background: Multidrug resistance gene 1 (MDR-1) encodes for P-glycoprotein (P-gp) recognized for removing cytostatic drugs from tumor cells. MDR1 gene polymorphisms change function of P-gp. In this study, we are interested in investigating whether MDR1 C1236T single nucleotide polymorphisms (SNPs) affect the susceptibility and treatment-related toxicities in B-cell non-Hodgkin lymphoma (B-NHL) in the population of eastern China.

Materials and methods: A group of 107 B-NHL patients and 150 healthy donors, unrelated ethnic Han Chinese and residents of eastern China, were included in this study. The MDR1 C1236T polymorphisms were determined using polymerase chain reaction-allele specific primers after extraction of genomic DNA. Analyses were performed using SPSS and Arlequin software.

Results: MDR1 C1236T polymorphisms were not significantly related to the risk and treatment-related toxicities of B-NHL. A significant association between extranodal sites and C1236T allele was observed (C vs T: P=0.01).

Conclusion: Our findings could expand our understanding of MDR1 in B-NHL and provide references for further research in multidrug resistance.
