Genome wide association studies have identified over two dozen single nucleotide polymorphisms (SNPs) that are associated with an increased risk of developing prostate cancer. Of note, all of these designs were case-control studies. In order to better differentiate between aggressive and indolent prostate cancer, Xu et al. performed the first casecase study design where 4,829 patients with aggressive prostate cancer were compared to 12,205 patients with less aggressive disease as defined by Gleason score. Their work, published in a recent issue of Proceedings of the National Academy of Sciences, identified a genetic variant, rs4054823, which significantly distinguished between the two natures of prostate tumors. Results indicated a 25% increased likelihood of developing aggressive prostate cancer with the TT genotype (p = 2.1 x 10 -6). While one biomarker alone does not warrant clinical change, this finding encourages future research to utilize a case-case genotyping methodology in order to effectively characterize risk of aggressive prostate cancer. Delineation would benefit clinicians in their diagnosis and treatment and ultimately would reduce the number of men who are overtreated from PSAbased screening.
