Abstract

This consensus statement, conceived as a joint initiative of the Spanish Society of Pathology (SEAP) and the Spanish Society of Medical Oncology (SEOM), makes diagnostic and treatment recommendations for the management of patients with advanced or metastatic melanoma based on the current scientific evidence on biomarker use. This document thus provides an opportunity to improve healthcare efficiency and resource use, which will benefit these patients. Based on the data available so far, this expert group recommends routinely testing patients with metastatic melanoma for BRAF mutation status, as the result affects the subsequent therapeutic management of these patients. The analysis of genetic alterations in KIT may be reasonable in patients with primary tumours in acral or mucosal sites or on chronically sun-exposed skin, in an advanced condition, but not in patients with other types of melanomas. This panel believes that testing for other genetic alterations, such as NRAS mutation status in patients not carrying BRAF mutations, GNAQ/GNA11 mutational analysis or genetic alterations in PTEN, is not currently indicated as routine clinical practice, because the results do not influence treatment planning in these patients at the present time. Other important issues addressed in this document are the organisational requirements and quality controls needed for proper testing of these biomarkers, and the legal implications to be borne in mind.
