Rare urinary bladder carcinomas: Clinic’s own case series

Abstract

Introduction: To date, the scientific reports dealing with the rare urinary bladder carcinomas are few, and this is clear by searching the literature review in the German medical journals. These reports are fewer than required to conclude a therapeutic regime. In addition, there is a clear lack of randomized trials concerning these rare disease. Case Series: In this case series, nine cases of rare bladder carcinomas were examined over one year. The aim is to give attention to the importance of conducting prospective, multicenter, randomized studies with long-term follow-up to define therapeutic regimens for these rare carcinomas. Conclusion: The German guidelines lack therapy guidelines that concern with rare carcinomas of the urinary bladder. The insufficient data necessitate further investigations to be continued in order to optimize treatment options. A possible solution would be a central urological registry that is accessible for all national and international practicing urologists.
