Abstract

Study Type – Aetiology (prospective cohort)Level of Evidence 2BOBJECTIVE•To compare survival after prostate brachytherapy in patients aged ≤60 years with patients aged >60 years.PATIENTS AND METHODS•We analysed 419 locally confined prostate cancer patients, treated between 1989 and 2001 with I-125 implantation monotherapy.•Endpoints were biochemical failure (BF) according to the +2 ng/mL definition, disease-specific and overall survival.•Patients were subdivided into age ≤60 years and age >60 years.•Cox proportional-hazards regression analyses were performed to study the independent effect of age on BF and disease-specific survival.RESULTS•The younger cohort consisted of 87 patients (21%), with smaller prostate volumes and a lower average prostate cancer risk class than the older cohort, consisting of 332 patients (79%). Mean follow-up was 9.1 years (±sd 2.8) for the younger cohort and 8.3 years (±sd 2.9) for the older cohort.•The 10-year (95% CI) freedom from BF, disease-specific survival and overall survival rates were 63% (51–75), 87% (78–96) and 81% (69–89), respectively, for the younger cohort and 46% (39–54), 83% (78–89) and 60% (54–66), respectively, for the older patient cohort.•Although a trend for better freedom from BF and disease-specific survival was observed in younger patients, the difference proved not clinically significant.CONCLUSION•Prostate cancer risk group and the year of treatment relate to outcome, but not age. With respect to prostate cancer curability, there seems no objection to offer brachytherapy to patients aged 60 years and younger.
