Researchers at University of California - San Francisco Report Findings in Prostate Cancer (Genome-wide association study of prostate-specific antigen levels identifies novel loci independent of prostate cancer)
By a News Reporter-Staff News Editor at Cancer Weekly -- New research on Oncology - Prostate Cancer is the subject of a report. According to news reporting originating in San Francisco, California, by NewsRx journalists, research stated, "Prostate-specific antigen (PSA) levels have been used for detection and surveillance of prostate cancer (PCa). However, factors other than PCa-such as genetics-can impact PSA."
The news reporters obtained a quote from the research from the University of California - San Francisco, "Here we present findings from a genome-wide association study (GWAS) of PSA in 28,503 Kaiser Permanente whites and 17,428 men from replication cohorts. We detect 40 genome-wide significant (p <5 ? 10) single-nucleotide polymorphisms (SNPs): 19 novel, 15 previously identified for PSA (14 of which were also PCa-associated), and 6 previously identified for PCa only. Further analysis incorporating PCa cases suggests that at least half of the 40 SNPs are PSA-associated independent of PCa. The 40 SNPs explain 9.5% of PSA variation in non-Hispanic whites, and the remaining GWAS SNPs explain an additional 31.7%; this percentage is higher in younger men, supporting the genetic basis of PSA levels."
According to the news reporters, the research concluded: "These findings provide important information about genetic markers for PSA that may improve PCa screening, thereby reducing over-diagnosis and over-treatment."
