RECURRENCE, PROGRESSION AND SUCCESS IN STAGE TA GRADE 3 BLADDER TUMORS TREATED WITH LOW DOSE BACILLUS CALMETTE-GUERIN INSTILLATIONS

Abstract

Our study demonstrates the high progression potential of stage Ta grade 3 tumors, since nearly 50% recurred and 25% progressed to invasive disease. These results may be closely compared with the results of previous trials of stage T1 grade 3 disease. We suggest that recurrence should be detected at an early stage using long-term followup with strict observance of the surveillance protocols during a minimum 5-year tumor-free period.
