Lymphatic Metastasis and Sentinel Lymphonodectomy

Metastases determine malignancy. The main attention so far has been focused upon organ metastases. The molecular mechanisms thereof, while far from being totally elucidated, are increasingly well understood. Modern diagnostic tools now enable detection and precise localization of small lesions. In contrast, our knowl­ edge and diagnostic capabilities regarding metastatic spread to the'lymphatic system are rather limited. However, there have re­ cently been a number of interesting advances. It is
