Electrochemotherapy of Posterior Resection Surface for Lowering Disease Recurrence Rate in Pancreatic Cancer (PanECT Study)

The aim of the study is to evaluate toxicity and effectiveness of electrochemotherapy (ECT) with bleomycin in pancreatic cancer in clinical study phase I and II. After surgical resection of pancreatic cancer, the posterior resection surface will be treated with ECT with the intention to lower disease recurrence rate. The study will include 10patients in phase I clinical study and additional 10patients in phase II clinical study (or in the extension of the clinical study), which will fulfill inclusion criteria. Treatment effectiveness will be evaluated by US or CT imaging, to detect early local recurrence of the disease. Long term effectiveness of the treatment will be evaluated by frequent and precise patient follow-up. During follow-up clinical examination, laboratory tests, tumor markers (Ca 19-9 and CEA) and US/CT imaging will be 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.
