The investigation for common hepatic cartery lymph node metastasis of esophageal squamous cell carcinoma / 中华胸心血管外科杂志

ABSTRACT

Objective:To investigation for common hepatic cartery lymph node metastasis of esophageal squamous cell carcinoma.Methods:From 2015 to 2017, 413 patients with esophageal squamous cell carcinoma who were dissected the common hepatic cartery lymp node were admitted in Cancer Hospital of Sichuan. The relationship between metastatic of rates of common hepatic cartery lymp node and the clinical data including sex, age, tumor site, diameter of tumor, invasion depth, differentiation degree, pathological stage, neurovascular invasion status were reviewed retrospectively.Results:A total of 10 649 lymph nodes were dissected.The lymph node metastatic rate was 45.27%(187/413), and the metastatic lymph node ratio was 7.96%(848/10 649). Lymph nodes adjacent to the middle esophagus, cervical esophagus, cardia of stomach had a higher metastatic rate, while the Lymph nodes adjacent to the hilar, supraclavicular, common hepatic cartery had a lower metastatic rate.A total of 775 lymph nodes were dissected in common hepatic cartery.The lymph node metastatic rate was 7.02%(29/413), and the metastatic lymph node ratio was 4.51%(35/775). To analysis the relationship between metastatic of rates of common hepatic cartery lymp node and the clinical data.We conclusion that the common hepatic artery lymph node metastatic rates of upper, middle and lower esophageal squamous cell carcinoma were 2.89%(2/69), 5.35%(12/224) and 12.50%(15/120), with significant difference.The common hepatic artery lymph node metastatic rates of patients with diameter of tumor under 3 cm, 3-5 cm and above 5 cm were 5.20%(9/173), 5.52%(9/163)and 14.28%(11/77), with significant difference.The common hepatic artery lymph node metastatic rates of sex, age, tumor site, diameter of tumor, invasion depth, differentiation degree, pathological stage, neurovascular invasion status, with no significant difference.Conclusion:The metastatic rates of common hepatic artery lymph node in esophageal squamous cell carcinoma is lower. For the upper thoracic esophageal cancer with tumor diameter under 5 cm, the dissection of common hepatic lymph node can be ommitted in surgery.
