B-RAF Inhibitors: An Evolving Role in the Therapy of Malignant Melanoma

Current Oncology Reports Aims and scope Submit manuscript

Abstract

Immunotherapy and chemotherapy benefit few patients with metastatic melanoma, and even fewer experience durable survival benefit. These poor results come from treating melanoma as a single homogeneous disease. Recently, it has been shown that targeting activated tyrosine kinases (oncogenes) can mediate striking clinical benefits in several cancers. In 2002, a mutation at the V600E amino acid of the BRAF serine/threonine kinase was described as present in over 50% of melanomas. The mutation appeared to confer a dependency by the melanoma cancer cell on its activation of the MAP kinase pathway. The frequency and specificity of this mutation (95% at V600E of BRAF) suggests that it may be a potential target for therapy, and recent results with one inhibitor, PLX4032/RG7204, bare this out. This review updates the status of BRAF inhibitors in melanoma and what may be on the horizon.

Sequencing of kinases in the MAP kinase pathway in a number of cancer cell lines reveals the presence of mutations in the BRAF gene in nearly 70% of melanoma samples (cell line, short-term cultures, or fresh tumor samples). These mutations are overwhelmingly found at the 599 amino acid (later determined to be 600) with a V to E mutation. The mutation appears to lead to transforming activity for the altered gene product.
