title: The effect of age on prostate implantation results.
abstract: OBJECTIVE
  The current study was undertaken to determine the effect of young age (60 years or younger) on the 5-year biochemical disease-free survival rate following ultrasound-guided transperineal prostate implantation.
  
  
  METHODS
  The radiation therapy charts of 330 patients who underwent ultrasound-guided transperineal prostate implantation who were treated from 1992 through 2004 were retrospectively reviewed. Follow-up ranged from 12 to 120 months, with a mean of 48 months. A total of 63 patients were 60 years of age or younger, and 267 patients were over 60 years of age. Prostate-specific antigen (PSA) recurrence was defined as three successive increases following ultrasound-guided transperineal prostate implantation. Biochemical disease-free survival was determined using the life-table method.
  
  
  RESULTS
  There were no statistically significant differences in the 5-year biochemical disease-free survival rates for the younger versus the older group. On univariate analysis, age was not a statistically significant factor in predicting PSA failure. Univariate analysis revealed that Gleason score, PSA at diagnosis, and clinical T stage were significant in predicting for PSA failure. Patients with Gleason score<7, PSA<10, and clinical stage T1c disease had statistically significant lower PSA failure rates than patients with Gleason score>or=7, PSA>or=10, and clinical stage T2 disease, respectively.
  
  
  CONCLUSIONS
  Patients who are 60 years of age or younger who are treated with ultrasound-guided transperineal prostate implantation can expect 5-year biochemical disease-free survival rates similar to those of older patients treated with ultrasound-guided transperineal prostate implantation therapy.
