    Abstract:
    OBJECTIVE: To determine the survival of patients at our institution who were clinically tumour-free (cT0) on re-staging transurethral resection (TUR) after treatment with chemotherapy for muscle-invasive bladder cancer. PATIENTS AND METHODS: In all, 55 patients with muscle-invasive, organ-confined transitional cell carcinoma of the bladder were treated with TUR followed by systemic chemotherapy, over a 10-year period. Patients were separated into two groups, those who were clinically T0 and those who showed persistent disease (>cT0) on re-biopsy after chemotherapy. Overall and disease-specific survival rates were calculated for the two groups. The cT0 group was further followed for tumour recurrence and clinical outcomes. RESULTS: Thirty-one patients (56%) were clinically T0 on TUR after chemotherapy; of these patients, 22 (71%) either died from other causes (with no disease recurrence) or are alive and with no evidence of disease at a mean follow-up of 53 months. Twenty of the 31 patients (65%) have retained their bladder with no evidence of cancer recurrence at a mean follow-up of 46 months. Disease-free status (cT0) at the time of TUR after chemotherapy was associated with significantly higher overall and cancer-specific survival (hazard ratio 3.40, P = 0.003; and 8.63, P = 0.001, respectively). CONCLUSION: Previous studies suggest that surveillance can be a reasonable option for patients with muscle-invasive transitional cell carcinoma of the bladder who show no evidence of disease on TUR after chemotherapy. Patients with persistent bladder cancer on re-biopsy after chemotherapy tend to fare poorly even with immediate cystectomy.
