Patient-Reported Outcome Measures and Decision Regret After Salvage Radical Prostatectomy for Recurrent Prostate Cancer Following Radiotherapy or Focal Therapy.

BACKGROUND/OBJECTIVES: Radical prostatectomy (RP) may be considered for recurrent prostate cancer (PCa) following primary curative-intended local therapy. The effect of different prior therapies on patient-reported outcome measures (PROMs) after RP is not well defined.

METHODS

Validated PROMs (SF-12, EPIC-26, Decision Regret Scale) were used to compare health-related quality of life (HRQOL) and functional status changes following salvage RP after radiotherapy (RT-sRP) or focal therapy (FT-sRP), relative to primary RP.

RESULTS

Among 26,515 RP patients who underwent RP between 2014 and 2024, 107 (0.4%) previously received radiotherapy (RT-sRP) and 98 (0.4%) previously received focal therapy (FT-sRP). Compared with primary patients before RP, only the sexual function of RT-sRP patients was lower (EPIC score, 51 vs. 75, < 0.001). One year after RP, RT-sRP patients exhibited lower functional status in all EPIC-26 domains compared to primary RP patients, whereas FT-sRP patients did not differ significantly. For instance, the median 1 yr EPIC-26 urinary incontinence scores were 46 (RT-sRP), 86 (FT-sRP), and 92 (primary RP). In adjusted mixed model analyses, the detrimental effects of RT-sRP vs. primary RP were further validated. In contrast, no such association was observed for FT-sRP. Decision regret and severe complications were low.

CONCLUSIONS

Prior FT had only a marginal effect on HRQOL and functional status following RP, while urinary continence and sexual function were lower for RT-sRP patients as compared to primary RP patients. However, from an overall PROM perspective, prior therapies did not exert a prohibitive effect that would preclude RP as a treatment option in those patients.
