Background:
The authors tested the performance of the currently used clinical criteria reported in populations studied by van den Bergh et al and Carter et al for the selection of patients with prostate cancer (PCa) for active surveillance (AS) according to age.
Methods:
Data were analyzed from 893 patients who underwent with radical prostatectomy (RP). The authors investigated the rates of unfavorable PCa at RP (extracapsular extension, seminal vesicle or lymph node invasion, or Gleason score 7-10) in patients who fulfilled AS criteria according to age tertiles (ages ≤ 63 years, 63.1 to 69 years, and >69 years). Area under the curve (AUC) [corrected] analyses tested the criteria for predicting unfavorable PCa. Then, the patients were stratified according to the cutoff age of 70 years. Multivariate analyses were used to test the role of age in predicting unfavorable PCa.
Results:
The rate of unfavorable PCa characteristics was between 24% and 27.8%. In the van den Bergh et al population, after age 70 years, the rate of unfavorable PCa characteristics was 41% compared with 23.2% and 24.1% in patients in the previous age tertiles (ages ≤ 63 years and 63.1 to 69 years, respectively). In the Carter et al population, the rate of unfavorable PCa was 41.2% compared with 17.3% and 18.6% in the previous age tertiles (ages ≤ 63 years and 63.1 to 69 years, respectively). When the 70-year age cutoff was used, unfavorable PCa was identified in 17.9% to 23.6% of patients aged <70 years versus 4% to 41.2% of patients aged >70 years (all P < .001). AUC analyses revealed significantly lower performance in older patients. In multivariate analyses, after adjustment for prostate-specific antigen, prostate volume, and the number of cores, age represented an independent predictor of unfavorable PCa.
Conclusions:
The currently used AS criteria performed significantly better for patients aged <70 years. The authors concluded that the current results should be taken into account when deciding whether to offer active surveillance to patients with low-risk PCa.
