Zusammenfassung
Über viele Jahrzehnte war die komplette Ausräumung der axillären Lymphknoten im Sinne einer Axilladissektion ein Standardverfahren in der Therapie des Mammakarzinom. Die Zielsetzung lag in der Bestimmung des histologischen Nodalstatus für die Festlegung der adjuvanten Therapie sowie in der Sicherung der lokoregionären Tumorkontrolle. Neben der Diskussion zur Optimierung der Therapiestrategien in der systemischen Behandlung und in der Strahlentherapie fokussieren aktuelle Diskussionen insbesondere auch auf die Verbesserung der chirurgischen Maßnahmen beim Mammakarzinom. Unter Berücksichtigung der zunehmenden Bedeutung der neoadjuvanten Chemotherapie erfährt die operative Behandlung des Mammakarzinoms sowohl im Bereich der Brust als auch im Bereich der Achselhöhle einen Wandel. Basierend auf der derzeitigen Datenlage wird die SLNE vor einer neoadjuvanten Chemotherapie grundsätzlich nicht empfohlen. Demgegenüber wird die operative axilläre Intervention – von der SLNE über die TAD bis zur ALND – nach der neoadjuvanten Chemotherapie als Vorgehen der Wahl zum axillären Staging angesehen. Zur Verringerung der Falsch-negativ-Rate des operativen Stagings der Axilla bei pN+CNB vor NACT und ycN0 nach NACT sind Targeted axillary Dissection (TAD), die Entfernung von > 2 SLNs (SLNE, kein ungezieltes axilläres Sampling), die Immunhistochemie zur Detektion von isolierten Tumorzellen oder Mikrometastasen und die Markierung von positiven Lymphknoten vor NACT als Standard anzusehen. In dem aktuellen Update zur operativen axillären Intervention wird auf die Bedeutung von isolierten Tumorzellen und Mikrometastasen nach neoadjuvanter Chemotherapie und die klinischen Konsequenzen einer mittels SLNE und TAD diagnostizierten Low Volume residual Disease eingegangen und ein Überblick bez. der diesjährigen AGO-Empfehlungen zum operativen Management der Axilla im Rahmen der Primäroperation und im Zusammenhang mit der neoadjuvanten Chemotherapie gegeben.
