Neues, nicht chirurgisch implantierbares Katheter-Port-System zur lokoregionalen Chemotherapie des fortgeschrittenen Harnblasenkarzinoms

Abstract

A new method to treat advanced urinary bladder cancer with locoregional chemotherapy has been developed which can be implanted by the radiologist. So far 3 patients with urinary bladder cancer invading the surrounding anatomical structures were treated. A 5F catheter is introduced into the internal iliac artery by the translumbar approach. Then, this catheter is exchanged with a coaxially assembled catheter port system over a guide wire. A subcutaneous tunnel through the puncture site is formed to receive the port. 10 mg mitomycin were infused three times at intervals of one to three weeks. Computed tomograms and cytoscopy showed complete disappearance of the tumour.
