Therapies targeting epidermal growth factor receptor (EGFR) are a promising recent development in the treatment of metastatic colorectal cancer (mCRC). Panitumumab is a fully human anti-EGFR monoclonal antibody that competitively inhibits the binding of all known EGFR ligands, including epidermal growth factor and transforming growth factor alpha, to cells expressing EGFR. In patients with mCRC, panitumumab monotherapy has resulted in favorable clinical responses, including increases in objective response rate, stable disease rate, and progression-free survival. Panitumumab has also shown promising antitumor activity in combination with selected chemotherapy regimens. Responses and improvements in progression-free survival associated with panitumumab monotherapy in patients with mCRC appear to be confined to patients whose tumors express wild-type KRAS. Therapy with panitumumab is generally well tolerated; the most common adverse events observed include skin-related toxicities, gastrointestinal toxicities, and hypomagnesemia. Infusion reactions are rare, and the agent has low immunogenicity.

Colorectal cancer (CRC) is the third most common cancer in men and the second most common in women worldwide. In Latin America and the Caribbean, it has a mortality of 56%. The median overall survival for patients with metastatic colorectal cancer (mCRC) is currently estimated as ~30 months, which has substantially improved through strategic changes in treatment and in the management of patients. As opposed to other metastatic cancers where first-line regimens are often determined, mCRC requires special attention because there is controversy in the possible combinations of the available drugs and the different periods of duration for each patient. Each combination must seek to be effective and to generate the minimum adverse effects as possible. Instead of giving the first-line regimen until the tumour progresses, treatment is often individualised. Furthermore, up to 60% of colorectal tumours are considered non-mutated or wild-type CRC. Not harbouring mutations in the RAS family of genes or mutations in the signalling pathways of the epidermal growth factor receptor causes a null response to anti-epidermal growth factor receptor antibody therapy, which implies even more complex considerations regarding its management. The primary objective of this consensus is to address the main scenarios of mCRC in order to warrant the most appropriate therapeutic intervention for these patients in the Central American and the Caribbean (CAC) region. This can lead to better clinical outcomes as well as quality of life for palliative patients. This document includes the formal expert consensus recommendations for scenarios of mutated and non-mutated mCRC, including synchronous or metachronous disease, management of mCRC with liver and lung metastasis, resectable, potentially resectable or non-resectable tumours and local in the CAC context.
