Pancreatic cancer, particularly when it spreads (metastatic pancreatic ductal adenocarcinoma or mPDAC), is a severe condition. Current treatments, like chemotherapy, only extend life by a few months. Radiofrequency ablation (RFA) is a technique that uses heat to destroy cancer cells. It is being explored for its potential to help patients with this type of cancer. This study focuses on patients whose cancer has spread to the liver. It involves applying RFA to the bile duct, where the cancer often causes blockage. The goal is to see if this can improve survival. Participants will be split into two groups: one will receive a metal stent in their bile duct, and the other will receive RFA followed by a stent. RFA is expected to help by destroying tumor tissue and improving bile flow.

• Study involves two groups: one with RFA treatment and one without.
• Participants must have limited cancer spread to the liver.
• Includes patients aged 18-85 under chemotherapy.
