Background. The regimens of therapy with bortezomib have significantly improved the survival among patients with multiple myeloma (MM). However, the development of peripheral polyneuropathy (PP) resulting from treatment using proteasome inhibitors is still an undesirable event. Risk factors for PP in MM patients include old age, previous neuropathy and use of neurotoxic drugs. Recent studies have established the presence of a genetic component in the mechanism of developing bortezomib-induced neurotoxicity. However, there are conflicting opinions on the role of genetic characteristics in predicting the risk of treatment-induced neuropathy development.Aim. To identify the risk group of bortezomib-induced PP based on the analysis of gene polymorphism of the immune response in patients with newly-diagnosed MM.Materials and methods. A study of the association of 20 polymorphic loci of 14 immune response genes in 46 MM patients was conducted using a candidate gene identification approach. All the patietns were receiving VCD therapy with bortezomib.Results. The distribution of single nucleotide polymorphisms was compared in groups of patients with the presence and absence of PP. It is found that homozygous carriers of the wild type allele of the genes TLR6 (Ser249Pro) (p = 0.006), IL1β (G-1473C) (p = 0.04), IL4 (C-589T) (p = 0.04), as well as haplotype carriers with the mutant allele of the gene IL10 (G-1082A) (p = 0.04) and with the wild type allele gene IL2 (T-330G) (p = 0.01) were significantly more frequent among PP patients.Сonclusion. Our results have confirmed the contribution of the genetic component to the risk of developing bortezomibinduced neuropathy. These findings can be used for individualization of therapeutic approaches to the treatment of MM patients.
