Persistence, Recurrence, and Progression Rates of Superficial Bladder Tumours after Resection Using the Differentiated Technique

Abstract

Objective: To investigate whether the differentiated resection technique for excising superficial bladder cancer leads to higher recurrence and progression rates as compared with regular resection. Subjects and Methods: We evaluated 163 patients, 66 undergoing a differentiated and 97 a regular resection. All patients underwent a routine second resection within 6–10 weeks. Recurrence and progression rates as well as tumour persistence on second resection were analyzed. Results: Patients with differentiated resections of bladder tumours did not have higher tumour recurrence and progression rates. Also, these patients had a significantly higher percentage of tumour-free second resections (p = 0.03). Conclusion: The differentiated resection technique for excising superficial bladder cancer has no negative influence on recurrence and progression rates, but it leads to a reduced tumour persistence.
