Two- versus three-field lymphadenectomy for esophageal cancer. A systematic review and meta-analysis of early and late results.

This study aims to estimate whether prophylactic cervical lymphadenectomy for esophageal cancer influences the short- and long-term results through a systematic literature review and meta-analysis. Twenty-eight articles were selected in this systematic review, encompassing 9180 patients. Prophylactic neck lymphadenectomy for esophageal cancer should be performed with caution, as it is associated with worse short-term results compared to traditional two-field lymphadenectomy and does not improve long-term survival.
