Summary:

      The study is prospective, phase II study, The primary objective of the study is evaluation of
      the feasibility and safety of intraoperative electrochemotherapy of colorectal liver
      metastases. The secondary objective is to determine the efficacy of electrochemotherapy
      treatment, based on histological and radiological evaluation of treated metastases. The
      endpoints are: toxicity according to the Common Terminology Criteria for Adverse Events
      (CTCAE) ver. 4.0 and response rate measured by percentage of vital tumor cells and mRECIST
      criteria.
