Your patient with melanoma: staging, prognosis, and treatment.

Melanoma, a cancer of melanocytes, pigment-producing cells in the skin, is the most serious form of skin cancer. Its incidence is increasing rapidly and reaching epidemic proportions. When detected early, it is considered curable, but when detected at later stages it is arguably one of the most lethal malignancies and is the cause of more years of lost life than any other cancer except leukemia. Because most cutaneous melanomas are visible, however, melanoma in general is a cancer highly amenable to early detection. Surgery is standard treatment for localized melanoma. There is no standard therapy for advanced-stage melanoma. Metastatic melanoma disseminates widely and it frequently involves sites that are not commonly affected in other cancers, such as the gastrointestinal tract and skin. The median survival time for patients with metastatic melanoma is less than 1 year. Despite these grim statistics, long-term survival occurs occasionally. This article will review diagnosis, staging, and treatment for malignant melanoma and will discuss the nursing role in the care of patients with melanoma.
