Summary

Pancreatic ductal adenocarcinoma (PDAC) remains a challenging malignancy, with over 300,000 patients diagnosed annually worldwide. Patients with metastatic pancreatic cancer (MPC) are generally not considered appropriate for operative management because it would not improve their prognosis. Developments in modern surgery and systemic treatment over the past decade have substantially improved the oncological outcomes for patients with PDAC. The prognosis can be further improved by using novel combined regimens. Systemic treatment is advantageous as it allows biological selection of patients and control of systemic lesions in patients with PDAC with only hepatic metastases (Hep-MPC), which may increase the likelihood of radical tumor resection and improved survival. Therefore, there is a strong need to reassess the value of surgery in Hep-MPC. Locoregional liver-directed treatments (LLDTs) are safe and efficient methodologies and have thus become the standard of care for patients with metastatic colorectal cancer (MCC) with liver-only or liver-dominant metastases. LLDT therapies include local liver resection, radiofrequency ablation (RFA), hepatic artery infusion pump chemotherapy (HAIP), stereotactic body radiation therapy (SBRT), and selective internal radiation therapy with yttrium-90 embolization (Y90). These therapies have been reported to influence the overall survival (OS), progression-free survival (PFS), and conversion to resection in patients with metastatic colorectal cancer. However, the data on the survival outcomes of conversion surgery and the clinical application of LLDT in Hep-MPC are sparse. Therefore, it remains unclear what types of treatment, based on the survival benefit, might actually be the optimal approach for Hep-MPC after effective systemic treatment. The present study aims to clarify the selection criteria of conversion surgery for Hep-MPC and explore the prognostic significance for its multimodal management, including surgical resection and/or LLDT.
