OBJECTIVES: To report the long-term results of bladder conservation strategies in elderly patients with muscle-invasive bladder cancer and evaluate the different factors affecting locoregional control and patient survival. METHODS: We reviewed the records of 39 elderly patients aged 70 or older, treated with curative intent with radiotherapy, with or without chemotherapy after transurethral resection of bladder for T2-T4aN0 carcinoma of the bladder. Twenty-seven men and 12 women were identified with a median age of 78 (range 70-87). Sixteen of the patients had a previous history of superficial bladder cancer. Twenty-five patients had T2 lesions, 13 patients had T3 lesions, and 1 patient had T4a lesion. The majority of patients were unsuitable for surgery because of medical reasons (67%), whereas the others refused radical cystectomy (33%). Patients were treated with radical radiation therapy with or without chemotherapy. RESULTS: At a median follow-up time of 35.5 months for patients at risk, the 5-year overall survival is 28.9% for all stages, 31.9% for T2 lesions, and 26.8% for T3-T4a lesions. Significant prognostic factors for overall survival on univariate analysis were performance status and age. Five-year cause-specific survival is 37.5% for all stages, 41.5% for T2 lesions, and 34.7% for T3-T4a lesions. No significant prognostic factors for cause-specific survival were indentified on univariate analysis. Toxicity was acceptable. CONCLUSION: Younger age and good performance status were favorable prognostic factors for overall survival. Bladder conservation strategies achieved satisfactory results and were well-tolerated in this elderly population with invasive bladder cancer.
