High grade superficial transitional cell carcinoma (TCC)
of urinary bladder remains a difficult situation to manage
even in premiere centers. Opinions differ as to whether
conservative or radical surgery is appropriate when high
grade (G3) tumors are diagnosed. Following transurethral
resection (TURBT) of the initial T1G3 tumor with no
additional therapy, there is a recurrence rate of 50% to
70% and a progression rate of 25% to 50%.
