Development of a Nomogram for Preoperative Estimation of Splenic Hilar Lymph Node Metastasis

A high-performing preoperative nomogram for predicting splenic hilar lymph node metastasis in non-greater curvature advanced proximal gastric cancer was developed. Tumor location, size, Borrmann type, and lymphadenectasis were key predictors. The nomogram showed good performance in both training and validation cohorts, aiding surgeons in making informed clinical decisions and leading to improved patient outcomes.
