Case report: Irreversible electroporation for locally advanced pancreatic cancer

INTRODUCTION For patients with pancreatic adenocarcinoma who are not candidates for surgical resection, long-term survival is poor, even with currently available systemic and radiation therapy options. However, for those with locally advanced disease who do not have distant metastasis, locoregional control of the tumor has the potential to improve long-term outcomes. A newly developed technology, irreversible electroporation, has advantages over traditional thermal ablation with unresectable cancers in this location. PRESENTATION OF CASE In our case report, we describe the first patient treated with irreversible electroporation at our institution for locally advanced pancreatic cancer. The patient is a 63-year-old man who had a partial response to standard chemotherapy and radiation, but was found on operative assessment to have persistently unresectable disease. He therefore underwent irreversible electroporation to the pancreatic mass. His postoperative course was complicated by delayed gastric emptying and wound infection. Three months after surgery, he had no evidence of distant or recurrent disease. DISCUSSION Irreversible electroporation for locally advanced pancreatic cancer is an emerging technique which attempts to improve local control of locally advanced, non-metastatic pancreatic cancer. Early data have demonstrated the potential for improved long-term survival in these patients, although further studies are needed to confirm safety and efficacy of this technique. CONCLUSION While there is a positive outlook for the use of irreversible electroporation for locally advanced pancreas cancer, there remain some uncertainties surrounding this therapy, which underscores the importance of future research in this area.
