TOPLINE:
according to a phase 3, open-label, randomized trial evaluating quality-of-life outcomes.
METHODOLOGY:
- Compared with prostatectomy, radiotherapy may offer better urinary and sexual outcomes but a higher risk for bowel toxicity in patients with localized prostate cancer. However, a comparison has not been performed in a randomized trial using more modern treatment options, such as SBRT.
- Researchers conducted the multicenter PACE-A trial to compare and evaluate quality-of-life outcomes among 123 patients (median age, 65.5 years) with low- to intermediate-risk localized prostate cancer who were randomly assigned to undergo either SBRT (n = 63) or radical prostatectomy (n = 60).
- Of the 123 patients, 97 (79%) had a Gleason score of 3+4 and 116 (94%) had National Comprehensive Cancer Network intermediate risk. The median follow-up was 60.7 months.
- The co–primary endpoints were urinary continence, measured by the number of absorbent urinary pads required per day, and bowel function, assessed using the Expanded Prostate Cancer Index Composite Short Form (EPIC-26).
- Secondary endpoints included erectile function (measured using the International Index of Erectile Function 5 questionnaire) , clinician-reported genitourinary and gastrointestinal toxicity, and International Prostate Symptom Score. Other patient-reported outcomes included EPIC-26 domain scores for urinary irritative/obstructive symptoms, and overall urinary, bowel, and sexual issues.
TAKEAWAY:
- At 2 years, only 6.5% (three of 46) of patients who ultimately received SBRT used one or more urinary pads daily compared with 50% (16 of 32) of patients who underwent prostatectomy (P < .001). Patients in the prostatectomy group reported worse EPIC-26 urinary incontinence domain scores (median, 77.3 vs 100; P = .003).
- Patients who underwent prostatectomy also had significantly worse sexual function scores (median, 18 vs 62.5 with SBRT; P < .001). Erectile dysfunction events of grade 2 or higher were significantly more common in patients who underwent prostatectomy (63% vs 18%).
- However, at 2 years, the bowel domain scores in the prostatectomy group were significantly higher than in the SBRT group (median, 100 vs 87.5), with a mean difference of 8.9.
- Overall, clinician-reported genitourinary and gastrointestinal toxicities were low in both treatment groups.
IN PRACTICE:
“PACE-A provides level 1 evidence of better outcomes of urinary continence and sexual function with worse bowel bother for SBRT, compared with prostatectomy,” the authors wrote, adding that the trial “provides contemporary toxicity estimates to optimize treatment decisions and maximize individual quality of life.”
SOURCE:
The study, led by Nicholas van As, of The Royal Marsden Hospital and The Institute of Cancer Research in London, was published online in European Urology.
LIMITATIONS:
The small sample size and differential dropout from allocated treatment could have introduced bias. Data completeness was another limitation.
DISCLOSURES:
The study was supported by grants from the Royal Marsden NHS Foundation Trust. Several authors reported having various ties with various sources.
