Current Updates in Bleomycin-Based Electrochemotherapy for Deep-Seated Soft-Tissue Tumors

Abstract

Electrochemotherapy (ECT) has evolved significantly during the last decade, expanding treatment indications from superficial skin lesions to advanced-stage, deep-seated tumors in hard-to-reach areas. Electrodes have also shown steady technological improvement throughout the years. Besides standard and VEG (variable geometry electrode) electrodes, the introduction of laparoscopic electrodes has brought on a new era in ECT treatment, making the minimally invasive approach a reality. The exact role of ECT in the oncological dashboard is yet to be determined; however, increased tumor response, pain relief, and a low number of adverse events may yield the way for more widespread application of the technique with possible further inclusion of ECT in international oncological guidelines. The aim of this review is to give an overview on the current status of ECT in deep-seated tumor treatment and shed light on its emerging role in local anticancer therapy.
