Metastasectomy in cutaneous melanoma

Metastasectomy remains the only treatment in malignant melanoma to offer complete pathologic response within a few days of in hospital stay. It has been historically associated with the highest survival rates in the literature reported for patients of this stage. However, only a minority of patients are amenable to curative resection of distant metastatic disease. This patient group exhibit slow growing oligometastases as indicated by: a. Long disease free interval after treatment of their primary tumours and b. An exhaustive preoperative work up with the use of PET/CT and MRI scans. Only complete resection of all metastases is associated with long term survival and de bulking should not be attempted. Metastasectomy has also been shown to offer significant palliation in cases of gastrointestinal bleeding or obstruction. The timing and the sequencing of surgery in the modern multimodal targeted treatment of melanoma is still unclear and warrants further investigation.
