Abstract

Purpose

To compare long-term (4–10 years) quality of life (QoL) of men with low-risk prostate cancer (PCa) treated by different modalities and a reference group without PCa.

Methods

In this cross-sectional study, four groups were sent a one-time QoL-questionnaire; PCa patients (1) following the structured Prostate cancer Research International Active Surveillance protocol, (2) who underwent radical prostatectomy (RP) in the context of the European Randomized study of Screening for Prostate Cancer—section Rotterdam, (3) who underwent radiotherapy (RT) at an academic hospital in The Netherlands, and (4) an age-matched reference group of men without PCa. The QoL-questionnaire addressed prostate-specific health (EPIC), generic health (SF-12), and anxiety (STAI-6). Statistical significance (p ≤ 0.05) and clinical relevance (≥0.5 SD) of differences between groups were assessed.

Results

The AS, RP, RT, and reference group response rates amounted to 74% (122/165), 66% (70/106), 66% (221/335), and 75% (205/273), respectively. At a mean of 6.6 years of follow-up, active surveillance (AS)-men reported better urinary function [M = 93.0 (SD = 10.6) vs. 80.0 (SD = 19.1), p ≤ 0.001], less urinary incontinence [M = 90.0 (SD = 14.6) vs. 70.1 (SD = 28.8), p ≤ 0.001], and better sexual function [M = 40.9 (SD = 24.6) vs. 14.8 (17.7), p ≤ 0.001, clinically relevant] than RP-men. Compared to RT, AS-men reported better sexual function [M = 40.9 (SD = 24.6) vs. 25.8 (SD = 25.0), p = 0.069]. The four groups reported similarly low anxiety levels; the number of highly anxious men (STAI ≥ 44) ranged from 8 to 13%. For all QoL domains, men on AS and men without PCa reported very similar scores.

Conclusions

Prostate-specific function of AS-men was significantly better than that of RP-men. When comparing AS to RT, a borderline significant difference in sexual function was seen. Men who followed an AS strategy for a long-term period were not anxious and accepted it well, suggesting that AS may be a good treatment option for men with low-risk PCa.
