[Minimal invasive surgery in breast carcinoma].

The presence or absence of involved axillary lymph nodes is the single best predictor of survival of breast cancer, and important treatment decisions are based on it. For staging purpose as well as for local control a level I and II dissection is recommended. In order to lower the morbidity of axillary lymph node dissection less invasive treatment modalities have been evaluated. Beside the sentinel lymph node biopsy another new method is discussed: the endoscopic axillary lymph node dissection. After liposuction of the axillary fat the lymph nodes of level I and II are removed by endoscopy. With this technique enough lymph node can be removed which allows a sufficient staging as well as local control. This technique is not to be recommended for general use unless long term results have proven its value.
