Results of radical cystectomy for primary bladder cancer. Retrospective study of more than 200 cases.
During a seven-year period 202 patients with primary bladder cancer had radical cystectomy with bilateral pelvic lymphadenectomy and urinary diversion. Lymph node metastases were found in 28.7 per cent. No significant differences in overall survival owing to age were apparent. Only extension and grade of histopathologic differentiation of the tumor proved to be an important prognostic factor. The five-year survival rates for pT1, pT2, pT3, and pT4 tumors were 76, 56, 19, and 0 per cent, respectively. In patients with deep invasive (T3 and T4) tumors no significant differences of survival rate depending on N and M categories were found. Nevertheless in pT3 tumors the probability of remaining alive was significantly decreased in those patients with histologic grade 3 compared with grade 2 tumors (P less than 0.01). The prognosis for patients submitted to radical cystectomy for bladder cancer has been classified as good: tumors confined to superficial muscle (pT1 and pT2); intermediate: tumors mildly differentiated infiltrating the deep muscle (pT3/G2); fairly poor: tumors undifferentiated infiltrating deep muscle (pT3/G3); and poor: adjacent invasive bladder tumors (pT4).
