Surgical management of distant metastases.
Although the location of metastases is of prognostic importance in stage IV melanoma, as seen in the revised AJCC staging classification system and other studies, certain guiding principles apply to patients who have any stage IV disease. Close follow-up of any patient who has melanoma may identify surgically resectable metastatic disease, although this method is controversial. Components of this monitoring may include careful questioning to determine symptoms, such as cough, abdominal pain, or headaches; physical examination for evidence of skin, soft tissue, and lymph node metastases; and screening tools, such as radiographs and laboratory tests. Identifying patients who have metastatic disease at the earliest stage possible is crucial for surgical resection to be an option. Patients should also be thoughtfully evaluated for the possibility of a complete surgical re-section. Complete metastectomy, regardless of the anatomic site, confers survival advantages not seen with other treatment modalities. This aggressive surgical approach should be tempered with the knowledge that incomplete resections put patients at increased risk without any proven survival benefit, and should be reserved only for palliation of symptoms. Systemic adjuvant therapies for stage IV melanoma are evolving, but do not yet confer the survival advantage of complete surgical resection. Until novel drug therapies show efficacy and significantly prolong survival in patients who have stage IV disease, careful consideration should be given to a complete metastectomy if technically feasible.
