Regional lymph node dissection is routinely performed forpatients with stage 3 metastatic melanoma to reduce the risk of localrecurrence and potentially improve survival. Method. A retrospectiveclinical audit was performed on patients who underwent lymph nodeclearance for stage 3 metastatic melanoma at Middlemore hospitalbetween 2010-2015 where patient demographics, surgical details,histology reports, complications and clinical outcome were recorded toidentify relevant risk factors. Result. 291 lymph node dissections wereperformed during the study period. Higher complication rate,specifically wound dehiscence was observed in groin dissectionscompared to axillary and neck dissections. Lymph node count below the recommended minimal node yield (as outlined by Sydney melanoma unit)are associated with poorer melanoma-specific survival rates. Complication rate, disease-specific mortality and outcome at the Middlemore unit are comparable to what has been reported in published literature.
