[Course of superficial carcinoma of bladder (Ta-T1). Apropos of 171 cases].
171 patients with superficial bladder carcinoma (Ta-T1) treatment by endoscopic surgery only, were followed during the period from 1.1.1976 to 31.12.1980. The effect of previous tumors in case history, multiplicity, cellular differentiation and tumor size on the frequency of recurrence and tendency to tumor progression was investigated. It was established that the size of tumor most influences the frequency of recurrence, followed by tumors in case history, multiplicity and epithelial anaplasia. A tendency to muscular invasion during recurrence depends mainly on the tumors size and its grade of cellular anaplasia.
