The last 30 years has seen a revolution in melanoma. Fundamental elements of the surgical, adjuvant medical, and systemic therapy for the disease have been significantly altered toward improved management and better outcomes. The intent of this article is to reflect on past efforts and research in melanoma and the current landscape of treatment of melanoma. The authors also hope to capture the excitement currently rippling through the field and the hope for a cure. The intent of treatment of advanced melanoma, which was once considered incurable, has changed from palliative to potentially curative.

Introduction
In 2014, an estimated 76,100 patients will develop new primary melanoma in the United States, and 9710 will die of this disease.1 In the United States, melanoma accounts for less than 5% of all skin cancers but is the leading cause of skin cancer mortality.2 The annual rate of increase of melanoma incidence is currently estimated at 3% compared with 6% in the 1970s to 1980s, but the overall mortality has been relatively stable since 1990.3 Worldwide the incidence of melanoma continues to increase; despite advances in local and systemic therapy, mortality continues to increase, with 80% of skin cancer-related deaths attributable to melanoma.4 Progress in the basic molecular biology and immunology of melanoma over the past 50 years has translated into improved outcomes for patients with localized disease as well as for those with systemic disease. The distribution of the burden of disease may be seen as inversely related to the opportunities to improve outcome. Advanced disease represents a smaller fraction of cases compared to earlier operable disease, associated with higher morbidity/mortality affording us greater opportunities for improved outcomes.5 Outcomes for patients with deeper primary lesions show a different picture. Those patients with deeper localized American Joint Committee on Cancer (AJCC) stage IIB/IIC disease have an increased risk of relapse and death, whereas patients with microscopic regional stage IIIA disease detectable with sentinel lymph node (SLN) mapping and biopsy have an intermediate risk. Recurrent nodal disease and bulky nodal IIIB-C disease have a relapse and mortality risk that approaches 70% or more at 5 years.5 Treatment and outcomes for advanced melanoma have improved over the past 20 years because of rapid advances in tumor cell biology, immunology, surgical techniques, radiosurgery, and imaging that are likely to further transform the field in the decade to come. This review reflects on the progress made in the past century and familiarizes the reader with the current state and management of melanoma.
Historical perspectives
Described in antiquity as a fatal black tumor, the term derived from Greek (melas “dark” and oma “tumor”) was coined by Dr Robert Carswell in 1838. References to this fatal black tumor can be found in the writings of the Greek physician Hippocrates in the fifth century bc, whereas those of Rufus of Ephesus emanate from the first century ad.6 Hunter is credited with the first resection of melanoma in 1787. Renè Laennec described melanoma as a disease entity and coined the term melanose to describe the tumor in 1804.7 Dr William Norris noted the heterogeneous appearance of the tumor and its propensity to metastasize in 18208 and first noted the heritable nature of melanoma and familial atypical multiple melanoma. In further publications, he observed that most of his patients had fair skin with light colored hair and the futility of surgery and medical therapy in the setting of distant metastases.9 Thomas Fawdington10 described one of the first cases of uveal melanoma and despaired at the lack of knowledge of therapies for this “insidious” process in 1820. In 1844, British surgeon Samuel Cooper11 recognized the benefit of the early removal of tumors and the untreatable nature of advanced disease.
Pathogenesis
Melanocytes in the epidermis of the skin produce the pigment melanin, which occurs in several forms that variably protect the skin from UV radiation. Most melanoma is sporadic. Environmental insults followed by proto-oncogene activation coupled with the suppression of tumor suppressor genes and defects in the DNA repair mechanism further exacerbated by the inability of the immune system to contain these insults result in melanoma. William Norris presciently observed the hereditary nature of melanoma and light hair and complexion associated with melanoma in 1857. He proposed that nevi and environmental exposures predispose to melanoma, observations that were validated in the discovery of the Familial Atypical Multiple Mole and Melanoma (FAMM) syndrome12,13 and the sporadic dysplastic nevus syndrome.14 The connection between UV radiation exposure and increased risk of melanoma in the Australian Caucasian population was described by Henry Lancaster in 1956 whose later work demonstrated the importance of skin characteristics in the cause of melanoma.15 These observations gave impetus to efforts to understand the genetics of melanoma. The discovery of the melanocortin receptor 1 (MC1R) on skin/hair phenotype16 and its highly polymorphic nature helped make the association between pale skin/fair hair with poor tanning response (English/Celtic ancestry) and melanoma. Approximately 40% of familial melanomas were attributed to a heritable germline mutation in the cyclin-dependent kinase (CDK) gene CDKN2A.17 Defects in CDK4, xeroderma pigmentosum, and MC1R genes have been implicated in familial melanomas.18–21 The discovery of the role of the Ras oncogene family in the 1980s and their effects on downstream signaling were the first steps toward the identification of driver mutations in melanoma.22 NRAS was first identified in a melanoma cell line in 1984.23 The identification of the mitogen-activated protein kinase (MAPK)/ERK and PI3K/Akt pathways of melanoma tumorigenesis followed. The mutations termed rapidly accelerated fibrosarcoma (RAF) were initially identified in Ewing sarcoma. Systematic genetic typing identified the V600E variant to be frequent in cutaneous melanoma in 2002.24 This mutation and its constitutive activation of the MAPK pathway have become the target of multiple pharmaceutical trials of small molecule inhibitors resulting in several new therapies approved by the Food and Drug Administration (FDA). The evaluation of other histologic subtypes led to the discovery of cKIT in acral and mucosal melanomas.25 Uveal melanomas exhibit driver mutations in GNAQ, GNA11, and BAP1 with a low incidence of BRAF.26 The differing pattern of driver mutations in different histologic subtypes of melanoma and the numeric burden of mutations in different melanoma cell lines from single tumors and in tumor samples ex vivo27,28 reflect the genetic heterogeneity of melanoma and are likely to have profound implications for the molecular and immunologic therapy for melanoma.
Risk factors
Melanoma is a disease that afflicts Caucasian Americans 20 times more commonly than African Americans. The lifetime risk of melanoma is approximately 2.0% (1 in 50) for Caucasians, 0.1% (1 in 1000) for African Americans, and 0.5% (1 in 200) for Hispanics. The risk of melanoma increases with age. The average age at incidence is 61 years; but it is not uncommon among those younger than 30 years, especially young women. Men have a higher lifetime risk than women. Previous history of melanoma is associated with an approximately 7% chance of developing a second primary melanoma....
