摘要: Prostate-specific antigen (PSA) screening has led to a significant rise in the number of men diagnosed with prostate cancer and an associated increase biopsies performed. Despite its limitations, including positive predictive value only 25%–40%, PSA remains generally accepted biomarker for cancer. There is need better tools not identify cancer, but also recognize those potentially lethal disease who will benefit from intervention. A great deal work been done worldwide improve our knowledge genetics behind specificity by developing assays different isoforms. Common genetic alterations patients have identified, CpG hypermethylation GSPT1 TMPRSS2:ERG gene fusion. Serum urine detection RNA biomarkers (eg, PCA3) tissue protein antibodies EPCA) are being evaluated prognostic tools. This article reviews some promising developments biomarkers.
