MP-13.01: Human Gene Polymorphism and Response to Bacillus Calmette-Guerin Immunotherapy for Superficial Bladder Cancer

The NRAMP1 gene has been implicated in susceptibility to tuberculosis and to BCG response in murine models. The Human glutathione peroxidase 1 (hGPX1) is a selenium-dependent enzyme that participates in detoxification of hydrogen peroxide, organic peroxides, and possibly cigarette smoke-derived oxidative radicals. An association between hGPX1 and NRAMP1, and bladder cancer recurrence has been suggested. We aim to determine the predictive value of NRAMP1 and hGPX1 gene polymorphisms in superficial bladder cancer recurrence and response to BCG therapy.
