Melanoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - General Information About Melanoma

Clinical staging is based on whether the tumor has spread to regional lymph nodes or distant sites. For disease clinically confined to the primary site, the greater the thickness and depth of local invasion of the melanoma are, the higher the chance of lymph node or systemic metastases, and the worse the prognosis is. Melanoma can spread by local extension (through lymphatics) and/or by hematogenous routes to distant sites. Any organ may be involved by metastases, but lungs and liver are common sites. The risk of relapse decreases substantially over time, though late relapses are not uncommon.[8,9]
