Abstract

Pancreatic cancer usually refers to ductal adenocarcinoma of the pancreas, accounting for more than 95% of pancreatic malignant tumors [1]. Surgical resection is the only effective method for pancreatic cancer patients to obtain a chance of cure and long-term survival. In the past, distant metastasis of pancreatic cancer was considered as a contraindication for surgery, and radiotherapy was recommended instead of surgical resection. With the development of surgical techniques, the safety of surgery was increased in recent years, and the death rate from surgery-related diseases has dropped to less than 5% [2]. Therefore, for patients with isolated distant metastasis of pancreatic head cancer, such as liver metastasis or lung metastasis, whether extended pancreaticoduodenectomy can be performed has aroused the interest of the majority of pancreatic surgeons.
