title: [Lymphadenectomy in surgery for cancers of the stomach and esophagus].
abstract: Lymph node invasion is the principal prognostic factor in cancers of the stomach and esophagus which have a tendency to early lymphatic spread.The anatomy of regional lymph node groupings is described and standard and extended types of lymphadenectomy are defined. We discuss he role of lymph node dissection - particularly extended lymphadenectomy - and assess whether there is demonstrable benefit in terms of morbidity and mortality, loco-regional recurrence, and survival. Articles from the surgical literature with the highest levels of evidence are analyzed. Practical guidelines for treatment choice are proposed.
