BACKGROUND: Prostate cancer (PCA) is one of the leading causes of death among men, being related to several factors, including the aging male population, like benign prostatic hyperplasia (BPH), a histopathological and hyperplastic alteration associated to prostate aging. The FASL, BCL-2 and BAX genes are involved in cell apoptosis regulation and can be related to the development of both cancer and hyperplasia. This study aimed to investigate the association of FASL - 844 (rs763110), BCL-2 -938 (rs2279115) and BAX - 248 (rs4645878) polymorphic variants in Southern Brazilian PCA and BPH patients and healthy controls. METHODS AND RESULTS: 348 samples were analyzed, being 123 from PCA patients, 143 BPH patients and 82 healthy controls, using PCR-RFLP techniques. The results of genotyping analysis were adjusted by age, and compared with PSA levels and prostate volume. The analyzes of genotype frequencies according to PCA, HPB and controls, were performed by logistic regression corrected by age, and showed that the FASL CC genotype can be a risk factor for PCA patients, when compared to controls (p = 0.041). The clinical data investigation indicated higher PSA levels in PCA patients with FASL CC genotype, as compared to TC genotype carriers (p = 0.044), higher PSA levels for healthy individuals with BCL-2 AA genotype, comparing with CC genotype (p = 0.027) and higher PSA levels in BPH group with FASL CC genotype, as compared to TC genotype (p = 0.044). CONCLUSIONS: Our data indicate the FASLCC genotype as a risk factor for prostate pathologies, whileBCL-2 CC can act as a protective genotype.
