Therapeutic lymphadenectomy in melanomas of the head and neck.

Abstract

This retrospective study describes patients with loco-regionally metastasized melanoma of the head and neck. All patients underwent a therapeutic lymph node dissection. The 3-year survival rate was 35%. Duration of disease-free interval, number of lymph nodes involved, and extent of neck dissection proved of no influence on survival rates. Locoregional recurrence occurred in 10 patients and always proved to be a sign of systemic dissemination. Ultimately, 19 patients developed systemic disease. More than 40% developed cerebral metastases and the cerebrum was the second most involved site. As cerebral involvement occurs often in head and neck melanoma, a computed tomography or magnetic resonance imaging scan of the brain is recommended in the routine work-up before lymph node dissection. Furthermore, because the extent of the surgical procedure had no influence on local recurrence rate and overall survival, a selective approach, preserving functional structures, is advocated.
