Abstract

The biologic behavior of the superficial bladder tumor is pleomorphic depending on tumor characteristics and there are many different ways to manage these superficial bladder tumor accordingly. Careful analysis of these characteristics can be provided for categorizing patients if those have low or high risk in the rate of recurrence and spread or progression of the tumor. 90 patients of superficial bladder tumor were analyzed to assess the prognostic importance of following variables : Tumor stage, grade, shape, multiplicity of tumor, ABH (0) blood group antigen from bladder mucosa and the modality of management, and the incidence of some variables was compared to 34 patients of invasive bladder tumor. The results showed that the recurrence rate was low and the prognosis was favorable in the case of low grade, low stage and solitary tumor, which has been performed transurethral resection followed by intravesical chemotherapy. Further study may be needed to give any significance of ABH(0) antigen as a factor which might suggest the prognosis of superficial bladder tumor in this analysis because the number of patients are not enough statistically.
