EDAP TMS SA announces the publication of positive pre-clinical results using intraoperative high intensity focused ultrasound (HIFU) ablation of the pancreas in the peer-reviewed journal Cancers. The paper, entitled, Intraoperative HIFU Ablation of the Pancreas Using a Toroidal Transducer in a Porcine Model. The First Step towards a Clinical Treatment of Locally Advanced Pancreatic Cancer, describes a pre-clinical study designed to assess the feasibility of using HIFU under Doppler guidance to treat the pancreatic parenchyma and tissues surrounding the superior mesenteric vessels in vivo, in an animal model.

Pancreatic adenocarcinoma is among the most aggressive of all cancers. Regardless of treatment, the overall 5-year survival rate for patients with locally advanced pancreatic adenocarcinoma (“LAPA”) is less than 5%. A HIFU approach could help in the treatment of such pathology that is inaccessible by other known therapeutic methods.

Apart from palliative chemotherapy, no other curative options have been proven effective for the treatment of LAPA. During the study, HIFU treatments were performed using an intraoperative HIFU probe which caused irreversible tissue necrosis in only a few seconds by producing sufficiently strong heat in the focal area. This study is the first step toward the launch of a Phase I study to evaluate the safety and feasibility of such a HIFU approach in patients with LAPA and to further confirm these encouraging results.
