[Comment] An old tool for new strategies in advanced prostate cancer
Summary
Prostate-specific antigen (PSA) was discovered in 1960 and introduced as a biomarker for prostate cancer in 1987.1 Since then, PSA has been used for screening, detecting recurrence after prostatectomy or radiotherapy, and monitoring treatment response. Early work also demonstrated that PSA concentrations measured 6–9 months after initiating castration represent a major prognostic factor in metastatic castration-sens…
