Objective:
The aim of this study was to define reliability of the sentinel lymph node technique in head and neck N0 melanoma. Identification of the sentinel node, which is the first evidence of melanoma metastasis, enables selective node dissection.
Materials And Methods:
Twelve patients with untreated localized cutaneous or mucous N0 melanoma of the head and neck were included in this study. After resection of the sentinel lymph node, type III neck dissection was performed during the same operative time in all twelve patients.
Results:
The sentinel node was successfully located by preoperative lymphoscintigraphy and confirmed at surgery in eleven patients. Five of these patients had evidence of metastatic node disease, always in the sentinel node. No other metastatic node were found in the neck dissection specimens. For the six other patients with a negative sentinel node, no other metastatic node was found in the neck dissection specimens.
Conclusion:
These preliminary results are promising. The sentinel node can be mapped and identified in most patients. No metastatic node was noted in patients with a negative sentinel node. If these results are confirmed, complete node dissection should only be performed in patients with a positive sentinel node in order to achieve more conservative surgical cure of head and neck melanoma.
