Metastases To Liver

This study is led by the Department of Hepatobiliary Surgery of the First Affiliated Hospital of the University of Science and Technology of China (USTC), in close collaboration with multiple participating centers nationwide. The primary objective is to establish a standardized, large-scale clinical cohort database specifically for metastatic liver cancer. By collecting comprehensive data on patient demographics, primary tumor characteristics, systemic therapies, and local interventions, this registry aims to elucidate the clinical patterns and prognostic factors of secondary liver malignancies. This database will serve as a robust platform for conducting high-quality real-world studies and advancing evidence-based clinical research in the management of metastatic liver cancer.

The goal of this clinical trial is to evaluate the safety of two durations of the Pringle maneuver in adults undergoing elective liver resection for malignant tumors. The main questions it aims to answer are: Is the incidence of post-hepatectomy liver failure different between 15-minute and 45-minute Pringle maneuver durations? * Do the durations differ in operative time or intraoperative blood loss? * Researchers will compare patients randomized 1:1 to 15 minutes vs 45 minutes of Pringle clamping to see if outcomes are non-inferior between groups. Participants will: * Undergo standard oncologic hepatectomy with the assigned Pringle duration. * Receive routine perioperative assessments, including laboratory tests and clinical evaluations. * Attend follow-up visits at approximately 6 months, 1 year, and 3 years after surgery.
