Conclusions

Abstract

— The progress made in the diagnosis and therapeutic possibilities of this type of tumour is underlined. Thanks to more precise pre-operative knowledge and staging of the neoplasm, nowadays a more selective as well as less invasive therapy can be applied (traditional, endoscopic and percutaneous surgery). In many cases topical pharmacological therapy can overcome recurrences of the disease while in particularly serious, extensive cases, extreme conservative surgery allows easy endoscopic access for endocavitary treatment during follow-up in order to avoid dialysis. There are many therapeutic solutions and methods for this type of tumour, but they must be studied in depth to be able to alternate them wisely, regulating the therapy according to the course of the disease.
