title: [Long-term survival of bladder preservation therapy with radiation and chemotherapy for locally invasive bladder cancer].
abstract: The prognoses and prognostic factors of the 54 patients with locally invasive bladder cancer who underwent bladder preservation therapy at Yokohama City University Hospital between 1977 and 1995 were analyzed statistically. The therapeutic modalities of bladder preservation were mainly radiation or chemotherapy. The prognosis for the patients who underwent bladder preservation therapy was worse than that for the patients who underwent total cystectomy. The prognostic factors of these patients were size and grade of tumor, presence of hydronephrosis and performance status (PS) of the patients by univariate analysis. Tumor grade was the most predictable prognostic factor using multivariate analysis. Only 17 patients survived more than 5 years after treatment; 78% of the survivors had good PS (0 or 1). Five of them died of cancer and two patients were alive with cancer. All of them had G3 tumors. These results suggest that patients with locally invasive G2 tumor could be candidates for bladder preservation therapy and patients who underwent bladder preservation therapy should be evaluated at 10 years post-therapy.
