ABSTRACT
OBJECTIVES:
The aim of this study was to investigate the prognostic impact of the surgical approach and adjuvant treatment in operable malignant melanoma of head and neck (MMHN).METHODS:
Retrospective reviews of 31 patients who underwent surgery-based treatment with curative intent, either by the endoscopic or external approach, for MMHN were performed to analyze recurrence patterns, salvage modalities, and oncological outcomes (disease-specific survival and disease-free survival).RESULTS:
Overall recurrence rate was 61% (19/31). In stage III patients (n=24), 50% (12/24) developed recurrences with a median recurrence-free period of 6.0 months, and 30% (4/12) of them was successfully salvaged by reoperation with adjuvant radiotherapy. On the contrary, all stage IVA patients (n=7) developed recurrences with a median recurrence-free period of 4.4 months. Distant metastasis was the most common pattern of failure and no patients were salvaged. Among variables, age and T classification, not the surgical approach, were significant prognosticators for disease-free survival and disease-specific survival. Adjuvant radiotherapy was associated with a lower rate of local failure, compared to surgery alone (hazard ratio, 0.02; 95% confidence interval, 0.06 to 0.75; P=0.02). However, adjuvant systemic therapy was not effective in reducing the risk of failures for any pattern.CONCLUSION:
Our data suggested that meticulous surgical resection, either by the endoscopic or external approach, with adjuvant radiotherapy increases the local control rate in MMHN.
