Summary

This study is a single-arm clinical trial of irreversible electroporation (IRE) for the treatment of unresectable locally advanced pancreatic cancer (LAPC).

The aim of the study is to evaluate the efficacy of IRE in this patient group. A statistical analysis of patient survival will be performed, comparing study participants to historical data from the Danish national database of pancreatic cancer patients.

Description

Patients with unresectable LAPC can be included in the study. Prior to inclusion, initial treatment with chemotherapy with or without radiation therapy (RT) is administered to all patients accord to the referring institutions protocol. Some patients will have undergone an attempted resection prior to inclusion. It is expected, that a substantial number of patients are participants in the LAPC-03 protocol (FOLFIRINOX followed by local therapy (resection, RT and/or IRE) in patients with LAPC).

After completion of initial therapy, potential study participants are restaged with a PET-CT scan and serum tumor markers. Patients found on restaging to be free of metastatic disease and without significant primary tumor progression will be candidates for IRE therapy. IRE therapy will be administered not earlier than 2 weeks after completion of initial therapy.

IRE will be done under general anesthesia as an in-patient procedure. Patients will attend study specific visits with PET-CT scan 3, 6, 9, 12, 18 and 24 months post-IRE. Patients will attend the out-patient clinic after 1, 3, 6, 9, 12, 15, 18, 21 and 24 months. During this we will monitor pain, quality of life, global functioning and nutritional status.

In patients who, at any time during the study, are assessed as candidates for resection, a more detailed re-evaluation of resectability is performed according to local preferences (e.g. EUS and/or LAP/LUS and/or CT and/or MR).
