Abstract

We hypothesized that the IL-1β-511 C>T polymorphism could be associated with the development of neurotoxicity and that it could be a possible biomarker to rate the risk of occurrence of neurotoxicity in cancer patients. Genomic DNA was extracted from 85 cancer patients: 49 received systemic chemotherapeutic treatment (CHT) and 36 patients did not receive it (No-CHT). All subjects were genotyped for the functionally active polymorphisms of IL-1β-511 C>T. We estimated neurotoxicity with the evaluation of neurological deficits. CHT patients showed erythrocytopenia, neurological deficit and a slight lowering of cognitive performance. The subgroup of patients carrying the CC genotype of the IL-1β-511 C>T gene showed lesser neurological deficits. In the context of cancer treatment, we suggested the potential value of IL-1β-511 C>T as genetic biomarkers to identify patients with higher risk to develop neurological deficits.
