[Development and validation of a preoperative prediction model for very early recurrence after radical resection of intrahepatic mass-forming cholangiocarcinoma].

The preoperative albumin-bilirubin grading and three CT imaging features, including tumor size, multi-nodular type, and arterial phase enhancement pattern, are independent risk factors for postoperative VER in IMCC patients. The clinical-imaging nomogram model constructed based on the albumin-bilirubin grading and these three imaging features can accurately predict postoperative VER in IMCC patients before surgery, providing a reference for the selection of individualized treatment strategies.
