Zusammenfassung
Das therapeutische Management des kolorektalen Karzinoms hängt entscheidend vom histologisch evaluierten Lymphknotenstatus ab. Erkenntnisse neuerer Studien weisen darauf hin, dass anstelle einer geforderten Minimalanzahl von zwölf Lymphknoten, die Präparation und histologische Untersuchung aller Lymphknoten eines Operationspräparates anzustreben ist. Dabei ist auch zu beachten, dass, trotz sachgemäßer Aufarbeitung durch den Pathologen, auch Fälle (insbesondere beim Rektumkarzinom) mit deutlich weniger als zwölf Lymphknoten vorkommen können.
Abstract
The detection of lymph node metastases is of vital importance for the therapeutical decision-making in patients with colorectal carcinoma. Due to the results of several recently published studies it seems to be most desirable to identify all lymph nodes rather than follow the recommendation to investigate a minimum number of twelve lymph nodes. However, it has to be noted that, despite a scrupulously exact lymph node recovery by the pathologist, in some cases (particularly in rectal carcinoma) substantially less than twelve lymph nodes may be yielded.
