Permanent prostate brachytherapy is safe in men with severe baseline lower urinary tract symptoms

PurposeTo evaluate the long-term urinary outcomes of men with severe pretreatment lower urinary tract symptoms (LUTS) treated with permanent prostate brachytherapy (PPB) ± external beam radiation therapy for localized prostate cancer.Methods and materialsA total of 105 men with International Prostate Symptom Score (IPSS) 20–35 before PPB were categorized by IPSS change at last followup: (1) worse = IPSS rise >3; (2) no change = IPSS change within three points of baseline; (3) improved = IPSS fall by >3 points. We then evaluated patients who worsened vs. those who did not (no change or improved) with respect to incontinence outcomes, LUTS medication usage, and predictors of symptom worsening.ResultsMean followup was 80.3 ± 55.8 months. Mean age was 66.3 ± 7.1 years; mean pretreatment IPSS was 23.6 ± 3.0. Overall mean improvement in IPSS was 7.6 ± 9.3. Specifically, 14.3% (15/105) worsened, 21.9% (23/105) had no significant change, and 63.8% (67/105) improved. There were no patient- or treatment-related factors significantly associated with long-term worsening of urinary symptoms. No men required anticholinergic therapy at last followup, whereas 7% (8/105) were using an alpha blocker. Only 2.9% (3/105) of men were using at least one pad daily at last followup. Alternatively, only 7.7% (8/105) reported subjective incontinence.ConclusionsPPB is an acceptable option in the setting of severe baseline LUTS in appropriately selected and counseled patients when performed by a skilled practitioner.
