Efficacy of Palliative Bladder Radiotherapy for Hematuria in Advanced Bladder Cancer Using Contemporary Radiotherapy Techniques

BACKGROUND/AIM: The aim of this study was to review the outcomes of palliative radiotherapy (RT) for hematuria treated with modern RT techniques. PATIENTS AND METHODS: This was a retrospective cohort study. The primary endpoint was symptom response rate. Secondary endpoints included symptom recurrence rate, overall survival and treatment-related toxicity. RESULTS: Median age was 82 years (range=36-98 years). Median biologically effective dose (BED) was 36 Gy. Sixty-seven percent of patients (39/58) responded to RT. The median survival duration was 5.6 months (range=0.02-47.6 months). One third (13/39) of responders had recurrence of hematuria. Competing Risk regression with death as the competing risk showed that patients treated with low BED regimen ( 36 Gy) (p=0.01). One patient (2%) developed grade 3 nausea and vomiting which required admission for intravenous hydration. CONCLUSION: BED regimens should be recommended as they are associated with a significantly lower rate of recurrent hematuria.
