Recurrence and survival after neck dissections in cutaneous head and neck melanoma

Abstract

Introduction: An important prognostic factor in head and neck melanoma is the status of the regional lymph nodes since the presence of metastatic disease in the nodes greatly aggravates the prognosis. There is no consensus on the surgical treatment algorithm for this group. Our aim was to study if there is a difference in nodal recurrence and survival after radical, modified or selective neck dissection.

Methods: A total of 57 patients treated for regional meta-stases of head and neck melanoma were analysed retrospectively with respect to type of neck dissection, use of sentinel node biopsy, nodal recurrence and survival.

Results: After a median 127-month (range: 22-290) follow-up period, we showed that there was no significant difference in nodal recurrence between three different dissection groups (11% for radical node dissection, 24% for modified radical node dissection and 23% for selective node dissection, p > 0.05). No significant difference in five-year survival was observed between the dissection types (56% for radical node dissection, 61% for modified radical node dissection and 48% for selective node dissection, p = 0.613). Multivariate and univariate analysis revealed that patients with metastatic deposits in sentinel nodes had a better survival than patients with clinically palpable nodes (five-year survival rate: 70% versus 36%, p = 0.008).

Conclusion: The extent of neck dissection does not significantly influence the rate of recurrence or survival. This study indicates that there is a survival benefit for patients who undergo completion lymph node dissection following a positive sentinel node biopsy.
