In recent years,endoscopic resection,particularly endoscopic submucosal dis-section,has become increasingly popular in treating non-metastatic superficial esophageal squamous cell carcinoma(ESCC).In this evolving paradigm,it is crucial to identify factors that predict higher rates of lymphatic invasion and poorer *** tumor size,deeper invasion,poorer differentiation,more infiltrative growth patterns(INF-c),higher-grade tumor budding,positive lymphovascular invasion,and certain biomarkers have been associated with lymph node metastasis and increased morbidity through retrospective reviews,leading to the construction of comprehensive nomograms for outcome *** validated by future prospective studies,these nomograms would prove highly applicable in guiding the selection of treatment for superficial ESCC.
