Randomized experimental treatment for colorectal cancer using an endoscopic device in combination with bleomycin or saline.

Primary objectives: The aim of this randomized trial, is to establish thesafety and efficacy of electrochemotherapy in patients with colorectalcancer, as an additive treatment prior to intended curative surgery. Theelectroporation regime in this trial will be delivered through andendoscopic device, EndoVE. The CliniporatorTM will be used for pulsegeneration
Primary endpoints: To investigate if electrochemotherapy is an efficient treatment modality for tumor down staging compared with electroporation alone prior to intended curative surgery in patients undergoing treatment for colorectal cancer.
