Biochemical recurrence after localized treatment

The quoted incidence of biochemical recurrence (BCR) after localized treatment varies significantly and depends on numerous well-known prognostic factors; however, it likely occurs in at least 30%-40% of patients who receive localized treatment. Because the clinical significance of BCR is often unclear, and depends in many cases on unknown factors, it is difficult to select the best treatment and determine when best to institute that therapy. This review examines some of the issues associated with BCR and attempts to shed some light on this common but controversial clinical scenario. Some treatment strategies discussed in this article include salvage radiotherapy after radical prostatectomy, salvage therapy after radiotherapy, and hormonal therapy.
