Three-Field versus Two-Field Lymphadenectomy for Esophageal Squamous Cell Carcinoma: A Meta-analysis.

Background: Most surgeons now accept lymphadenectomy as an essential feature of the operative treatment of esophageal squamous cell carcinoma. Three-field and two-field lymphadenectomy are two of the most popular excision scopes among surgeons. Over recent years, researchers have performed a range of comparative studies regarding these techniques, although the conclusions remain inconsistent.

Prognostic significance of the number of lymph nodes dissection in esophageal adenocarcinoma patients.

Background: Esophagectomy combined with lymphadenectomy has been considered as the preferred treatment option for esophageal cancer (EC). However, for a long time, no consensus is reached on the optimal number and scope of lymph node dissection (LND). In particular, related research on esophageal adenocarcinoma remains lacking at present.
