Clinical Guides in Oncology


Publication of this consensus statement is a joint initiative of the Spanish Society of Pathology (SEAP) and the Spanish Society of Medical Oncology (SEOM), intended to revise and update the diagnostic and treatment recommendations published 2 years ago on biomarker use and the management of patients with colorectal carcinoma (CRC), thereby providing an opportunity to improve healthcare efficiency and resource use in these patients. This expert group recommends testing for KRAS and NRAS status in all patients with metastatic CRC being considered for anti-epidermal growth factor receptor (anti-EGFR) therapy, as this type of treatment should only be used in patients not harbouring mutations in these genes. In contrast, testing for BRAF, EGFR, PI3K and PTEN mutation status is not necessary for therapeutic decision making, so does not need to be done routinely.





The authors are grateful for the editorial assistance of Ana Martín of HealthCo (Madrid, Spain) in the production of this manuscript. SEOM and SEAP are grateful for financial support for this project in the form of unrestricted grants from Merck, Sanofi and Roche.

Conflict of interest

The authors declare that, when writing and revising the text, they did not know the names of the pharmaceutical companies that provided financial support for this project, so this support has not influenced the content of this article.
