Objective: The aim of the current study was to investigate possible associations between catalase C262T (CAT C262T), glutathione peroxidase 1 Pro198Leu (GPX1 Pro198Leu), manganese superoxide dismutase Ala16Val (MnSOD Ala16Val) gene polymorphisms and non-Hodgkin Lymphoma risk (NHL) in a Romanian population and the five-year overall survival rate of the NHL patients.
Methods: We included in this case-control study 406 individuals, divided into two groups: the control group (n=315) and the patients group (n=91). The DNA was extracted from peripheral blood and amplified using specific techniques.
Results: The variant homozygous genotype of GPX1 Pro198Leu represents a risk factor for NHL development and no associations regarding the risk for NHL were found for MnSOD Ala16Val and CAT C262T gene polymorphisms. Two of the studied polymorphisms were associated with the overall survival rate thus: negative association regarding MnSOD Ala16Val, associated with higher overall survival rate and a positive one regarding CAT C262T, associated with lower overall survival rate.
Conclusions: According to our results, the mentioned polymorphisms may be considered as susceptible markers of the five-year overall survival rate for NHL patients. Future studies with a larger number of patients are needed to confirm our results.
