We investigated the potential prognostic roles of p53 (codon 72) and XRCC1 (codons 194, 280, and 399) polymorphisms in clinical localized prostate cancer after radical prostatectomy.
The decreased risk we observed with the hOGG1 326 Cys/Cys genotype confirms an earlier report and the further reduced risk found with the CYP1B1 (432 Leu/Leu or Leu/Val)-hOGG1 (326 Cys/Cys)-XRCC1 (Arg/Arg or Arg/Gln) genotype combination may lend new insights to the importance of ROS generated from non-receptor-mediated estrogenic mechanisms in more aggressive prostate cancer.
This is the first report on the studies of XPC and XRCC1 Arg194Trp polymorphisms in PC, and our present data suggest that XPC Lys939Gln and the T-A haplotype of XRCC1 Arg194Trp and Arg399Gln may be risk factors for PC in Japanese.
