Treatment of Liver Metastases With Electrochemotherapy

The aim of the study is to evaluate toxicity and effectiveness of electrochemotherapy with bleomycin in treatment of liver metastases of colorectal cancer in clinical study phase I and II. The study will include 10-15 patients with colorectal cancer with synchronous or metachronous liver metastases, but electrochemotherapy will be performed on metastasis not more than 3 cm in the largest diameter. Treatment effectiveness will be evaluated by magnetic resonance imaging (MRI) and ultrasonography (US) in a monthly interval. Two or three month after the first operation the treated and untreated metastases will be resected and through histological analyses performed. The secondary objectives of the trial are to quantify the impact of the treatment on the patient’s quality of life, tolerance to the therapy and suitability for larger study to be conducted.
