ABSTRACT
PURPOSE:
Hematuria following post-prostatectomy radiotherapy (PPRT) is inadequately characterized. We performed a consecutive cohort study of patients treated with PPRT at our institution to characterize this complication including impact on patient-reported quality of life. MATERIALS ANDMETHODS:
Patients with potential followup ≥4 years following PPRT were identified. Freedom from ≥grade 2 hematuria (FFG2H; macroscopic blood) was estimated using the Kaplan-Meier method. Predictors of ≥grade 2 hematuria (G2H) were assessed via log-rank tests and the Cox model. Urinary patient-reported quality of life by EPIC-26 (26-question Expanded Prostate Cancer Index Composite) was compared for patients with/without hematuria using mixed-effects regression.RESULTS:
A total of 216 men received PPRT (median 68.4 Gy, IQR 68.0-68.4) from 2007 to 2016 at a median of 20 months (IQR 9-45) after prostatectomy. Median followup was 72 months (IQR 54-99). A total of 85 men developed hematuria, of whom 49 (58%) underwent cystoscopy, 13 (15%) required intervention and 26 (31%) experienced recurrent hematuria. Eight-year FFG2H was 55%. G2H was highest in men treated with anticoagulation/antiplatelet therapy (HR 3.24, p <0.001), men with bladder V65 Gy ≥43% (HR 1.97, p=0.004) and men with medication allergies (HR 1.73, p=0.049). Age <65 years (HR 0.81, p=0.374) and diabetes mellitus (HR 0.49, p=0.098) were not associated with G2H. Change in urinary continence (mean -3.5, 95% CI 10.1, 3.1) and irritation/obstruction (mean -3.0, 95% CI 5.8, -0.3) domain scores did not exceed the minimally clinically important difference for men with/without hematuria.CONCLUSIONS:
Hematuria following PPRT is common, especially among men with medication allergies and those on anticoagulation/antiplatelet therapy; however, PPRT-related hematuria is typically self-limited. Limiting bladder V65 Gy may reduce PPRT-related hematuria.Palavras-chave
