Original description

Pancreatic ductal adenocarcinoma (PDAC) is a very aggressive cancer and may become the second leading cause of cancer death by 2030. About half of the patients are diagnosed late, when the cancer has already spread (mPDAC), and the outlook is very poor. Chemotherapy is currently the only treatment for mPDAC. It can slow the disease and slightly extend life, but usually only by a few months. There are no other treatments that clearly improve survival. Radiofrequency ablation (RFA) is a minimally invasive technique that uses high-frequency electrical energy to generate heat and destroy tumor cells. Radiofrequency energy raises the temperature of the tissue, leading to coagulative necrosis and tumor cell death. RFA is commonly used to treat certain types of cancer and pre-cancerous lesions, including liver, kidney, lung, and bone tumors. In addition to directly destroying tumor tissue, RFA may also enhance the immune system's ability to recognize and attack cancer cells by exposing tumor antigens that were previously hidden within the tumor mass. Most research on radiofrequency ablation (RFA) to date has focused on Barrett's esophagus and liver cancer. However, RFA is increasingly being explored in palliative care, where early results suggest potential benefits. Advances in miniaturized endoscopic technology have enabled the application of RFA in anatomically challenging locations, such as the bile duct. Studies, including case series and clinical trials, have demonstrated that RFA is both feasible and safe. However, its impact on overall survival remains uncertain. Many previous studies are limited by small sample sizes and heterogeneous populations, often including patients with different cancer types and disease stages, which introduces bias and limits the generalizability of findings. We have therefore designed a prospective study focusing on patients with bile duct obstruction due to pancreatic ductal adenocarcinoma (PDAC) with limited metastatic spread (oligometastatic mPDAC). This study aims to provide more robust evidence on the potential role of RFA in improving clinical outcomes in a carefully selected subset of patients with advanced PDAC.Read full original descriptionShow less
