Comparative effectiveness of radical cystectomy and radiotherapy without chemotherapy in frail patients with bladder cancer. Academic Article uri icon

Overview

abstract

  • Objectives: To evaluate cancer-specific (CSS) and overall survival (OS) in a group of frail patients who were treated with RT without chemotherapy and to compare them with a matched cohort of patients treated with RC.Methods: This study identified 71 patients treated with RT only for high-risk bladder cancer. Patients with metastatic (cN + or cM+) or non-resectable tumors (cT4) and those who received any form of chemotherapy were excluded. Patients where matched 1:1 using propensity scores which adjusted for the effects of age, clinical stage and age-adjusted Charlson comorbidity index (CCI). OS and CSS were evaluated using the Cox proportional hazards regression model and the Fine and Gray competing risk model.Results: In the overall population, RT was associated with worse OS (HR = 1.78, 95% CI = 1.15-2.77, p = 0.01) compared to RC, but not with CSS (HR 1.1, p = 0.74). In the matched cohort, RT was neither associated with OS nor CSS (p > 0.05) compared to RC. In the competing risk analyses no statistically significant association of any of the treatments was observed in the total or in the matched data set (p > 0.05).Conclusion: The use of RT may be an alternative option in well selected patients with limited disease who are considered unfit for systemic chemotherapy and RC. Future research should focus on improving patient selection and assess the quality-of-life as well as the need for reintervention in patients treated with RT.
