Extent of lymphadenectomy for esophageal cancer / 中华胃肠外科杂志

ABSTRACT

Esophageal cancer is a common malignant tumor in China. For resectable ones, surgery is still the primary treatment. At present, the extent of lymph node dissection remains controversial. Extended lymphadenectomy makes metastatic lymph nodes more likely to be resected, which contributed to pathological staging and postoperative treatment. However,it may also increase the risk of postoperative complications and affect prognosis. Therefore, it is controversial how to balance the optimal extent/number of dissected lymph nodes for radical resection with the lower risk of severe complications. In addition, whether the lymph node dissection strategy should be modified after neoadjuvant therapy needs to be investigated, especially for patients who have a complete response to neoadjuvant therapy. Herein, we summarize the clinical experience on the extent of lymph node dissection in China and worldwide, aiming to provide guidence for the extent of lymph node dissection in esophageal cancer.
