Biochemical recurrence of prostate cancer： the controversial ~ ecognition and management

Over the past decade, more and more patients diagnosed as prostate cancer have received radical management attributing to the advent of prostate-specific antigen （PSA） based medical screening. Radical prostatectomy （RP） and radiation therapy （RT） are the most commonly used forms of definitive therapy for clinically localized prostate cancer. However, despite these technique advances, biochemical recurrence （BCR）, as determined by subsequent rises in the serum PSA level, is still a challenge that urologists face.
