    Abstract:
    OBJECTIVES: To determine the long-term results of a bladder-sparing approach in the treatment of muscle-invasive bladder cancer. METHODS: Ninety-four patients with invasive transitional cell carcinoma of the bladder were treated by transurethral resection followed by 2 or 3 cycles of cisplatin-based chemotherapy. Patients were then treated with 6480 cGy of radiation in 49 patients, segmental cystectomy in 8, or surveillance only in 7. Patients who failed to respond to chemotherapy or radiation therapy, or who developed recurrent muscle-invasive disease in follow-up, underwent salvage cystectomy. Patients were then carefully followed for a median follow-up of more than 5 years. RESULTS: After initial therapy, 53 patients (56%) were alive with their bladder preserved. Thirty of those 53 (57%) developed a local recurrence in follow-up. After a median follow-up of more than 5 years, the ultimate relapse-free survival is 49% (Stage T2, 84%; T3, 53%; and T4, 11%; P < 0.01). Of all patients enrolled, 53% had bladder preservation; however, of the currently surviving patients, 16 of 39 (41%) have their bladders intact (T2, 50%; T3, 37%; T4, 0%). Only 18% of the initially enrolled population is alive with a preserved bladder. The 5-year survival of patients who had cystectomy at some point during the study, compared with those who have had their bladders preserved, was 65% versus 40%, respectively (P < 0.01). CONCLUSIONS: Our long-term results with multimodality therapy with attempted bladder preservation showed no definitive improvement in survival compared with modern series of cystectomy alone, and a disappointingly low rate of disease-free bladder preservation. We found a high rate of locally recurrent disease in the preserved bladders. We also noted a decrease in survival in our patients with bladder preservation compared with those without preservation. Bladder preservation, although possible, should be limited to a very select group of patients.
