Disseminated melanoma is an incurable disease whose prognosis has remained unchanged over the past 20 years. To date, no consensus treatment has emerged. No treatment strategy has proved superior to dacarbazine (Deticene) monochemotherapy that remains considered as the reference treatment for this disease. Both multidrug chemotherapy and biochemotherapy have provided disappointing results, with poorer quality of life and no survival benefit for the patients. Other treatment approaches, particularly immunotherapy, remain to be investigated in clinical trials.
