Description of the Evidence

Background Incidence and mortality There are three main types of skin cancer: Basal cell carcinoma. Squamous cell carcinoma (together with basal cell carcinoma referred to as nonmelanoma skincancer). Melanoma. Basal cell carcinoma and squamous cell carcinoma are the most common forms of skin cancer but have substantially better prognoses than the less common, generally more aggressive melanoma. Nonmelanoma skin cancer is the most commonly occurring cancer...

Added Risk Factors as a new subsection.

Cellular and Molecular Classification of Melanoma

Revised text to state that identification of activating mutations in the mitogen-activated protein (MAP) kinase pathway has led to the definition of molecular subtypes of melanoma and provided potential drug targets.

Treatment Option Overview

Revised text to state that prospective, randomized, controlled trials with both agents have not shown an increase in overall survival (OS) when compared with observation (cited Kirkwood et al. and Eggermont et al. as references 9 and 10, respectively.) Also added text about therapies that have impacted OS in patients with recurrent or metastatic disease that are now being tested as adjuvant therapy in clinical trials, including NCT01274338, NCT01667419, and NCT01682083.

Added text to state that these single agents are rarely curative, but the trials that incorporate these agents are testing combinations in an attempt to prevent development of drug resistance. Also added text about clinical trials that are testing targeted therapies in the smaller patient subsets.

Stage III Melanoma

Added text to state that prospective, randomized, multicenter treatment trials have demonstrated that high-dose interferon alpha-2b and pegylated interferon do not improve OS and agents that have demonstrated improved OS in patients with recurrent or metastatic disease are now being tested in clinical trials of adjuvant therapy in patients at high risk for relapse after surgical resection of tumor. These trials include: NCT01274338, NCT01667419, and NCT01682083.

Stage IV and Recurrent Melanoma

Added text to include checkpoint inhibitors in the treatment options list.

Revised text to state that although melanoma that has spread to distant sites is rarely curable, two approaches have demonstrated clinical benefit by prolonging OS in randomized trials: immunotherapy and inhibition of the MAP kinase pathway, adding that both ipilimumab and vemurafenib were approved by the U.S. Food and Drug Administration in 2011. Also added that although neither appears to be curative when used as a single agent, clinical trials are currently testing combinations of these and similar agents to prevent the development of resistance; additionally, ipilimumab and vemurafenib are available to newly diagnosed and previously treated patients.
