INTRODUCTION TO METASTATIC MELANOMA
Among new cancer cases documented in the United States in 2008, melanoma is estimated to be the sixth and seventh most common in men and women, respectively. This cancer has continued to rise in incidence at a rate exceeding those for all other cancers. In 2010, there were projected to be 68,130 new cases of melanoma, but the vast majority of these were forecast to be early-stage and therefore curable. However, it was estimated that 8,700 patients would die from this disease in 2010 [1]. Annually, about 8,000 patients are found to have metastatic melanoma presenting as a recurrence of an earlier primary melanoma; this number closely approximates the annual number of deaths from this disease. This statistic illustrates the lack of progress that has been made in the treatment of stage IV melanoma over the past several decades.
The American Joint Committee on Cancer (AJCC) divides cutaneous melanoma into four stages. Primary tumors confined to the skin without regional lymph node involvement are assigned stages I and II, depending on the thickness (depth) of the tumor, ulceration of the overlying epithelium, or invasion of the reticular dermis or subcutaneous fat (Clark level IV or V). Stage III is a disease with clinical or pathological evidence of regional lymph node involvement or with the presence of in-transit or satellite metastases. Stage IV disease is defined by the presence of distant metastasis [2].
