The Augsburg experience: histological aspects and patient outcomes

Ann Surg Oncol. 2001 Oct;8(9 Suppl):48S-51S.

Abstract

In Augsburg, sentinel lymphonodectomy (SLNE) was introduced into melanoma treatment in 1994. Diagnostic accuracy has been improved by early identification of sentinel lymph node (SLN) micrometastases and even more by their histomorphometric assessment. The S classification defines three categories of SLN metastases, S1 to S3, supplemented by S0 in the absence of metastasis. It is the leading predictor for the status of the remaining regional lymph nodes and an independent prognosticator for distant metastasis and survival. This should find consideration in adjuvant therapy trials. The pivotal question of whether SLN-guided surgery itself achieves survival benefit has been approached by a follow-up study that compared 387 SLNE-treated patients with 473 patients from the pre-SLNE era. In contrast to nonsignificant differences in patients with thin and very thick primary tumors, death from intermediate-thickness melanoma (1.51 to 4 mm) occurred significantly more often in the watch-and-wait group versus the SLNE group. These results must be validated by prospective randomized trials (e.g., NCI 29605).
