[Prognosis of the patients with high grade bladder carcinoma].
The pathological features and clinical outcome of grade 3 transitional cell carcinoma of the bladder, excluding CIS, encountered between 1972 and 1988 were studied to clarify the clinical characteristics of the disease. The subjects of this study were 108 patients consisting of 76 males and 32 females aged 33-87 years, with a mean age of 66 years. The survival rate according to each factor was calculated by Kaplan-Meier method, and the survival curves were compared by generalized Wilcoxon test. Grade 3 bladder cancer was often papillary, sessile and about 3 cm in diameter and showed a tendency of multiple occurrence. Histopathologically, it was often in high stages of pT2 or above and frequently with vascular invasion. Total cystectomy is not considered to be an absolute necessity for pT1, G3 bladder cancer patient, because, in our experience, it did not improve the prognosis. However, bladder-preserving operation requires strict postoperative follow-ups. After this operation, the 5-year survival rate was higher in the no-recurrence group than in the recurrence group, and the out come tended to be better in the group that had undergone intravesical instillation chemotherapy for prevention of recurrence than in the group without this therapy. Ample intravesical instillation chemotherapy after bladder-preserving operation seems to improve the postoperative course of bladder cancer patients. Total cystectomy may be unavoidable in patients with pT2 or above, and no effect of postoperative adjuvant chemotherapy was noted in our series. The establishment of multidisciplinary approaches is considered to be needed for improvement of the prognosis of high stage bladder cancer.
