OBJECTIVETo evaluate the correlation of the single nucleotide polymorphisms (SNPs) of the CYP1A2 gene with the stages and grades of prostate cancer (PCa).

METHODSWe conducted gene sequencing of the rs2069514-3859 (A > G) and rs2069525-1707 (C >T) alleles in the CYP1A2 gene in 253 patients with benign prostatic hyperplasia (BPH) and 206 patients with PCa treated by castration therapy, and statistically analyzed their correlations with the genotypes, stages and grades of prostate cancer.

RESULTSThe incidences of the 2 CYP1A2 SNPs showed no significant difference between the BPH and the castrated PCa patients (P > 0.05), and their genotypes were not correlated with the stages of PCa (P > 0.05). The Gleason scores were mostly <7 in the PCa patients with genotypes containing C in the rs2069525-1707 (C > T) allele (P = 0.030, OR = 4.658, 95% CI: 1.222 - 17.754).

CONCLUSIONSNPs of the CYP1A2 gene may have some correlations with the pathologic stages of PCa, but their mechanisms and clinical significance need to be further confirmed.
