Zusammenfassung

Hintergrund

Lokale Ablationsverfahren stehen in der Onkologie im Fokus aktueller Entwicklungen. Vorrangiges Ziel ist es, ohne Kompromittieren der onkologischen Ergebnisse, Organe und Organfunktionen zu erhalten.

Methode

Die irreversible Elektroporation (IRE) ist ein neues Ablationsverfahren und beruht auf einer induzierten Zellapoptose nach Applikation von Starkstromimpulsen ohne thermische Schädigung des Zielgewebes und benachbarter Strukturen.

Ziel

2005 erstmals publiziert, wird die IRE aktuell in einigen onkologischen Fachgebieten präklinischen und klinischen Untersuchungen unterzogen, die Ergebnisse sind bisher vielversprechend. Die IRE könnte eine deutliche Entwicklung in der Ablationstherapie beim Nierenzellkarzinom (NZK) bedeuten, der entscheidende Wirknachweis für das lokale NZK steht jedoch bisher aus. In dieser Arbeit werden eigene präklinische und erste klinische Untersuchungen und Ergebnisse dargestellt, diskutiert und mit anderen Ablationstechniken verglichen, um die aktuelle Wertigkeit der IRE aufzuzeigen.

Abstract

Background

Local ablation techniques are a major focus of current developments in oncology. The primary aim is to retain organs and preserve organ functions without compromising the oncological outcome.

Method

Irreversible electroporation (IRE) is a novel ablation technique that involves the application of high-voltage pulses to induce cell apoptosis without causing thermal damage to the target tissue or adjacent structures.

Aim

First published in 2005 IRE is currently undergoing preclinical and clinical trials in several areas of oncology and the initial results have been promising. The IRE technique could be a significant development in ablation treatment for renal cell carcinoma (RCC) but decisive proof of its effectiveness for local RCC has not yet been provided. This study presents the results of preclinical and initial clinical trials which are discussed and compared with those of other ablation techniques in order to demonstrate the current value of IRE.
