Do Patients With T1 Tumors Of The Bladder Cancer Have To Undergo Repeat Transurethral Resection

ObjectivesTo assess the value of repeat transurethral resection (TUR) in patients with newly diagnosed T1 bladder cancer.MethodsWe summarize 618 patients' clinical information in our study. We divided the data into the professional doctors' team and beginner doctors'team. Our resection margin is 1.0cm away from the tumor margin, and the deepness is to the deeper muscle layer or meeting the fat tissue. And some of the patients in each team underwent the ReTUR-BT. Patients in the both teams are followed up for 1-6 years. Then we analyze the result and review the involved literature.Result4-6 weeks after the initial resection,11 patients of the professional doctors'team underwent the repeated transurethral resection, all of which were reported non-recurrence through the biopsy. But in the beginner doctors'team,7 patients underwent the repeated transurethral resection, in which 5 patients were reported high grade urothelial cancer through the biopsy. And there are overall 96 patients have recurrence in the both teams within 3-30 months, where the recurrence tumor foci was over 2.0cm far away from the initial foci.ConclusionsFor the professional doctor, the scope of operation is qualified. The patients should not have to undergo repeated transurethral resection if the muscle biopsy reports no tumor invasion in addition.
