Systemic therapy in disseminated melanoma

There is no standard treatment for advanced melanoma. As long as metastases are satellites or in-transit metastases localized in a leg or arm, the prospects for curative treatment by isolation perfusion are good. But as soon as metastases have spread via the circulation, curative treatment with cytotoxic agents becomes virtually impossible. When the tumor burden is not too extensive, however, palliative treatment can be of clinical value. Some combinations of cytotoxic agents or combinations of biologic response modifiers have been shown to induce worthwhile remissions. Toxicity remains a problem, however. The advantages of the newer immunological approaches, especially with interleukin-2 (IL-2) and T-cell lymphocytes, is that treatment for a short period may result in good remissions at an early stage. Much clinical research is still needed to improve these costly approaches.
