Einleitung: Seit der Einführung der Sentinellymphknotenbiopsie (SLNB) zum axillären Staging bei Mammakarzinompatientinnen hat sich diese Operationstechnik in den meisten Brustzentren etabliert. Die Idee, mit einem weniger invasiven Eingriff als der axillären Dissektion den Nodalstatus exakt zu evaluieren, ist faszinierend und entspricht dem Gesamtkonzept in der Behandlung des Mammakarzinoms, den operativen Eingriff so wenig invasiv wie möglich zu gestalten. An wenigen Abteilungen wurde bereits dazu übergegangen, bei negativem Sentinellymphknoten (SLN) auf die Axilladissektion zu verzichten. Patientinnen und Methode: Von März 1998 bis März 2002 wurde an unserer Abteilung an 500 Patientinnen mit invasivem Mammakarzinom die Technik der SLNB angewandt. Anfangs wurde die Axilladissektion direkt im Anschluss an die SLNB durchgeführt. Nach der Lernphase an 75 Patientinnen mit einer Sensitivität von 96,2% und einer falsch negativen Rate von 3,8%, wurde bei Patientinnen mit negativem SLN unter definierten Voraussetzungen auf eine Axilladissektion verzichtet. Zusätzlich wurde aber das Spektrum erweitert und die Methode bei Patientinnen mit multizentrischem Karzinom und bei Patientinnen nach neoadjuvanter Chemotherapie evaluiert. Zur Auffindung des SLN wurde die kombinierte Methode mit blauem Farbstoff und mit Technetium 99m markiertem Humanalbumin verwendet. Ergebnisse: 500 SLNB wurden durchgeführt. Die Detektionsrate für das gesamte Kollektiv betrug 86,2%. Nach Bereinigung der Patientinnen mit multizentrischem Karzinom und der Patientinnen nach neoadjuvanter Chemotherapie betrug die Detektionsrate 94,5%. Insgesamt war der SLN in 41,3% der Patientinnen positiv, in 58,7% der Patientinnen negativ. Diskussion: Die SLNB ist eine probate Alternative zur Axilladissektion bei Patientinnen mit Mammakarzinom unter definierten Voraussetzungen.

Sentinel lymph node biopsy (SLNB) is a widely used technique for axillary staging in breast cancer patients. The principle to evaluate the axillary status of a breast cancer patient with a less invasive surgery than axillary lymph node dissection (ALND) meets the new minimally invasive concept in breast cancer surgery. Some breast cancer centers proceed to SLNB without ALND in SLN-negative patients.Between March 1998 and March 2002, 500 SLNBs were performed. After a learning period with SLNB and ALND in 75 patients with a sensitivity of 96.2% and a false-negative rate of 3.8%, SLNB alone without further ALND was performed in a group of patients. In addition, the feasibility of SLNBin patients with locally advanced breast cancer, in patients after neoadjuvant chemotherapy and in patients with multicentricity was evaluated. The combined method with blue dye and technetium-99m-labeled human albumin for identification of SLNs was applied.500 SLNBs were performed. The identification rate was 86.2%. After exclusion of patients with neoadjuvant chemotherapy and patients with multicentricity, the identification rate was 94.5%. SLNs were positive in 41.3% of patients and negative in 58.7% of patients.SLNB is an excellent method for axillary stag-ing and an alternative for ALND in a certain group of breast cancer patients.

We investigated 15 patients with unilateral facial paralysis using gadolinium(Gd)-DTPA (diethylenetriamine pentaacetic acid) enhanced (magnetic resonance imaging (MRI). Eleven were idiopathic and 1 each was due to basal skill trauma, Lyme's disease, Foville's syndrome and herpes zoster oticus. Ten of 11 Bell's palsies showed a significant enhancement of the facial nerve on the paralysed side. In all cases enhancement was shown in the labyrinthine segment, in 9 in the meatal segment, in 8 in the mastoid segment and in 7 in the tympanic segment also. Follow-up Gd-enhanced MRI investigation was performed 3-11 months later in 8 patients. In 1 case with incomplete return of function after 3 months MRI enhancement was decreased. We could not find any correlation between the intensity of the Gd enhancement and the course, severity or outcome of Bell's palsy, or stapedius reflex audiometry. The mechanisms and aetiology of the Gd enhancement in Bell's palsy seem to be non-specific phenomena which are also found in post-traumatic facial lesions, for instance. Nevertheless, the ability to image the facial nerve in Bell's palsy provides a new means of examination in this disorder. In our opinion Gd-enhanced MRI is recommended in cases of recurrent or "atypical" Bell's palsy and in cases with total loss of electrical excitability, to exclude tumours. It is further suggested that MRI may provide valuable information concerning areas which may require surgical exploration or decompression.
