Zusammenfassung

Die Entfernung und Untersuchung regionärer Lymphknoten bei der operativen Behandlung von gastrointestinalen Tumoren spielt eine wichtige Rolle in der Planung einer eventuellen adjuvanten Therapie. Sowohl die Anzahl der regionären Lymphknotenmetastasen als auch die Zahl der entfernten und untersuchten Lymphknoten ist für die Abschätzung der Prognose von Bedeutung. Für die Klassifikationen der regionären Lymphknoten ist es wichtig, sich darüber im Klaren zu sein, welche Lymphknoten laut Definition der UICC-TNM-Klassifikation mit eingeschlossen werden sollen, welche Definitionen für die einzelnen N-Kategorien gelten und welche Empfehlungen für eine Mindestzahl von zu untersuchenden Lymphknoten bei den jeweiligen Tumorentitäten bestehen.

Abstract

Removal and examination of regional lymph nodes play an important role in the surgical therapy of gastrointestinal tumors concerning potential adjuvant treatment strategies. The number of metastatic regional lymph nodes as well as the number of removed and examined lymph nodes are of importance regarding estimation of the prognosis. It is essential to consider which lymph nodes are defined as regional in the UICC TNM classification and which definitions apply for the individual N categories. Furthermore, it is necessary to define which recommendations are valid for the minimum numbers of lymph nodes to be removed and examined for particular tumor entities.
