Core Tip
Core tip: High-quality lymphadenectomy is an essential part of radical resection of gallbladder cancer. However, until now, no frequently used radiological modalities could satisfy the need of precise preoperative evaluation of lymphatic status, including ultrasonography, computed tomography (CT), magnetic resonance and positron emission tomography, and most patients with lymphatic metastasis (LM) could not be detected until postoperative pathology. This study discovered two risk factors of LM as age < 60 years and carbohydrate antigen 19-9 elevation. By combining these two factors to direct radiological detection of LM on CT, the total percentage of LM detected preoperatively could have a drastic increase from 31.3% to 81.8%.
