Overview
This is an monocenter, single arm, clinical investigation that evaluate the impact of the method on the objective response rate (ORR) of visceral lesions undergoing electrochemotherapy. Electrochemotherapy is a well-defined method for the treatment of cutaneous and subcutaneous metastases of different tumor histotypes.
Although still limited, the various experiences in the treatment of visceral localizations, particularly in liver metastases from colorectal cancer are promising and show that electrochemotherapy is a safe treatment, even in the case of lesions near large vessels or nerves. The investigators therefore propose a clinical investigation with a Medical Device according to EU Regulation 745/2017, using electrochemotherapy (Cliniporator) with bleomycin for the treatment of visceral, primary or secondary, unresectable localizations, with percutaneous or intraoperative technique (laparoscopic or laparotomy), as needed.
Description
This is a single-center clinical investigation with the enrollment of at least 24 patients with visceral, primary or secondary localizations, of any histotype, with particular reference to liver cancer, liver metastases from colorectal cancer and melanoma, primary pancreatic tumors, retroperitoneal sarcomas, abdominal and/or peritoneal localizations from melanoma and non-melanoma skin cancer (Merkel cell carcinoma, Squamous cell ca).
