However, few randomised trials have assessed the benefits and harms of radical prostatectomy (RPX), radiation therapy (XRT) and watchful waiting/observation to provide the evidence base for treating men with clinically localised PCA. The Scandinavian Prostate Cancer Group-4 (SPCG-4) trial randomised 695 men diagnosed in the pre-prostate-specific antigen (PSA) era, most had palpable disease, to surgery or observation.1 After a median follow-up of 13.4 years, surgery reduced PCA deaths by 44% (HR=0.56; 95% CI 0.41 to 0.77; absolute risk reduction=11 percentage points). All-cause mortality was reduced by 12.7 percentage points. Reductions were confined to men <65 years of age. The Prostate Cancer Intervention Versus Observation Trial (PIVOT) randomised 731 men from the early PSA era to RPX or observation.2 After a 10-year median follow-up, surgery did not reduce disease-specific mortality (HR=0.63; 95% CI 0.36 to 1.09). There was also no significant reduction for all-cause mortality. Absolute differences were 10 ng/mL or intermediate risk disease (p for interaction=0.11 for PCA mortality in both subgroups).
