Core Tip

Core Tip: This study investigated the effectiveness of various pathological sampling protocols for detecting microvascular invasion (MVI) in hepatocellular carcinoma. Conventional 7-point sampling methods have a high false-negative rate for MVI detection. However, the study revealed that whole-mount slide imaging, particularly when three consecutive interval whole-mount slide imaging from the tumor center are used, significantly improves diagnostic accuracy. This innovative approach improves the detection of MVI, especially in distant nonneoplastic liver tissue that have previously been ignored, offering a more reliable method for postoperative prognosis.
