The Importance of the Depth of Invasion in Stage T1 Bladder Carcinoma: A Prospective Cohort Study

Abstract

The prognosis is poor in patients with deep lamina propria invasion (stage pT1b) treated with transurethral resection alone. Patients treated with radical cystectomy had excellent survival regardless of the depth of invasion in the lamina propria. Radiotherapy was associated with poor survival.
