Head and neck cutaneous melanoma: a retrospective observational study on 146 patients.
BACKGROUND
Sentinel node biopsy (SNB) is a novel staging technique in cutaneous melanoma, but it is more challenging in the head and neck (H&N) than in the trunk and extremities. The aim of this study was to investigate the utility of SNB in patients with clinical stage I-II H&N cutaneous melanoma, with emphasis on disease outcome.


METHODS
Twenty five patients with H&N melanoma of >1.0 mm in Breslow depth underwent SNB and were compared to 121 historic H&N melanoma patients, who had either undergone routine prophylactic neck dissection or had been observed without any invasive nodal staging.


RESULTS
Sixteen percent of the SNB patients were sentinel-positive and there have been no false-negative cases. In the Kaplan-Meier analysis, there were no significant differences between the study groups in melanoma-specific overall survival. Among the entire cohort, melanoma-specific overall survival rate was 67.1% at 5 years and 61.9% at 10 years. Predictive factors for worsen survival were nodal micrometastases, male sex, scalp location, thick primary lesion and ulceration.


CONCLUSIONS
SNB is a reliable and mini-invasive approach for the nodal staging of H&N cutaneous melanoma. Traditional neck dissection is recommended only for therapeutic purposes in clinically node-positive or sentinel-positive patients.
