Abstract

We reviewed 261 patients who underwent a radical operation at a single institution as definitive treatment of invasive bladder cancer to evaluate the survival and accuracy of the tumor, nodes and metastasis system in characterizing the prognosis. Between January 1979 and June 1987 the 261 evaluable patients underwent 1-stage radical cystectomy with pelvic node dissection and urinary diversion. No chemotherapy and/or radiation therapy was given before or after the operation. The postoperative mortality rate was 1.8%. The over-all staging error between clinical and pathological stages was as high as 44%. The over-all actuarial 5-year survival rate was 54.5%. The 5-year survival rates were 75% for stage pT1, 63% for stage pT2, 31% for stage pT3 and 21% for stage pT4 disease. A significant difference in the survival (p less than 0.002) was observed in stage pT3 by dividing tumors confined within the bladder wall (pT3a, 50%) from those extending throughout the bladder wall (pT3b, 15%). A careful evaluation of transitional cell involvement of the prostate in stage pT4a cancer led to the identification of 2 different patterns: 1) contiguous when a bladder tumor extended directly into the prostate through the bladder wall and 2) noncontiguous when a bladder tumor and a transitional cell carcinoma of the prostate were found simultaneously. These patterns had completely different (p less than 0.05) survival rates (6 versus 37%). The patients with high grade tumors had a worse prognosis in comparison with those with grades 1 and 2 tumors (41 versus 56%, p less than 0.005). The over-all 5-year survival of patients with positive nodes was 4% in comparison with 60% of those without nodal involvement (p less than 0.001). Despite current optimal surgical treatment, nearly 50% of all patients with invasive bladder cancer continue to die. The need for a modification of the current tumor, nodes and metastasis tumor classification to provide the clinician a more reliable staging system for planning treatment modalities is indeed mandatory.
