Evaluation and Predictive Value of Genetic Polymorphisms in the Management of Hormonal Treatment of Prostate Cancer

Androgen deprivation therapy (ADT) by surgical castration or administration of LHRH agonists or antagonists is the gold-standard systemic treatment of Prostate Cancer. The efficacy, severity and frequency of side effects of ADT vary from a patient to another. The exact cause of this variability is not known, however certain genetic polymorphisms affecting enzymes implicated in the synthesis and metabolism of sex-steroids seem to be involved in these processes. To perform a longitudinal study to evaluate the prevalence of various genetic polymorphisms affecting genes in the sex-steroid synthesis and metabolism pathway (CYP1A1, CYP1B1, CYP19A1, 17HSD, HSD3B1, AR, ESR1, ESRRG, IL6, TNF-alpha) in men with Prostate Cancer receiving ADT and the possible association between polymorphisms and frequency and severity of side-effects of ADT.
