Objectives:
The absence of tumor in up to 10% of cystectomy specimens of patients with invasive bladder cancer justify the search for non aggressive therapies. The present study attempts to establish the safety and curative capacity of TUR alone for patients with superficial muscle-infiltrating bladder cancer.
Methods:
Over a period of 18 months, 12 patients with superficial muscle-infiltrating bladder cancer (T2) were diagnosed at our department, TUR was repeated in 9 of the 12 patients. The extension study was negative in all 9 patients.
Results:
The mean follow up was 12.8 months (range 7-70 months). Local recurrence was found in 4 patients (44.4%) who were submitted to another TUR; 3 were superficial and 1 invasive (with the same muscle involvement as at the initial diagnosis). The tumor-free survival rate was 9.3 months. No patient showed tumor progression.
Conclusion:
The percentage and nature of local recurrence, tumor-free survival and the progression rate (which was not observed during the short follow up period) indicate that TUR is a treatment option that must be taken into account in selected patients with invasive bladder cancer.
