PURPOSE: To evaluate our long-term results of bladder preservation with brachytherapy in the treatment of bladder cancer. METHODS AND MATERIALS: Between 1987 and 2000, 108 patients with T1-G3 and T2-T3a stages of bladder cancer were treated with a transurethral resection (TUR) and a course of external beam radiotherapy (30 Gy in 15 fractions) followed by brachytherapy (40 Gy). All tumors were solitary lesions with a diameter < or =5 cm. Median follow-up was 54 months (range, 1-178 months). RESULTS: The 5-year and 10-year overall survival rates were 62% and 50%, respectively. The 5-year and 10-year disease-specific survival rates were 73% and 67%, respectively. The actuarial local control rate was 73% at 5 and 73% at 10 years, respectively. The 5-year and 10-year disease-specific survival rates for patients with a preserved bladder were 68% and 59%, respectively. Of all long-term surviving patients, 90% preserved their native bladders. The treatment was well tolerated. Acute toxicity was mild. Two patients experienced serious late toxicity: 1 patient developed a persisting vesicocutaneous fistula and the other a stricture of the urethra and ureters. CONCLUSION: For patients with solitary, organ confined invasive bladder cancer < or =5 cm, bladder preservation with brachytherapy is an excellent alternative to radical cystectomy and combined modality treatment.
