IMPORTANCE: Historically, patients with cervical metastases from melanoma of the head and neck were treated with a radical neck dissection. This study evaluates the efficacy of limiting the extent of lymphadenectomy in this high-risk population.
OBJECTIVES: To determine whether limiting the extent of lymphadenectomy for patients with biopsy-proven melanoma has a negative effect on regional control. Our hypothesis was that performing a more limited lymphadenectomy does not have a negative impact on regional control.
DESIGN, SETTING, AND PARTICIPANTS: A retrospective, single-cohort study was performed using a prospectively collected database of patients with head and neck melanoma with histopathologically positive lymph nodes after modified radical (MRND) or selective neck dissection (SNDs) performed at a high-volume, academic, tertiary care center.
INTERVENTIONS: Lymphadenectomy was performed as clinically indicated.
MAIN OUTCOMES AND MEASURES: Primary end points were regional recurrence and regional recurrence free survival. Univariable and multivariable analyses were conducted using multiple patient characteristics.
RESULTS: Forty-one patients underwent SND or MRND from 2001 through 2010. The median number of positive nodes was 1 (range, 1-16). Twenty-six patients (63%) received adjuvant radiation and 23 patients (56%) received adjuvant immunotherapy or chemotherapy. The median follow-up time was 17 months (range, 1-116 months). Regional control was achieved in 29 patients (71%). Median regional recurrence-free survival was 21 months (range, 1-116 months). Age (hazard ratio [HR], 1.13; 95% CI, 1.01-1.26), total number of nodes examined (HR, 1.05; 95% CI, 1.01-1.10), and number of sentinel lymph nodes examined (HR, 1.45; 95% CI, 1.01-2.09) were all significantly associated with increased recurrence-free survival. Tumor depth, extracapsular spread, number of nodes positive, prior SLNB, extent of lymphadenectomy, and adjuvant therapy were not significant.
CONCLUSIONS AND RELEVANCE: Limiting the extent of lymphadenectomy with frequent use of adjuvant radiation therapy is effective in achieving regional control of head and neck melanoma with cervical metastases.
