Management of cutaneous melanoma: Comparison of the leading international guidelines updated to the 8th American Joint Committee on Cancer staging system and workup proposal by the Italian Society of Dermatology

The melanoma care landscape is changing fast in the last years. As a result of new insights in melanoma biology, prognosis and therapeutic options, both the American Joint Committee on Cancer (AJCC) and the World Health OrgaÂnization (WHO) Classification of Skin Tumors underwent substantial changes in 2018. Consequently, all the leading guidelines on melanoma management have been updated. Most of the recommendations derive from systematic reÂviews, while others are based on expert opinion, due to the lack of high-level evidence in some aspects of melanoma management. We provide a revision of all the available guidelines that have been updated to the 8th version of the AJCC classification system. Comparison is not provided for topics on which there is agreement on the standard of care.
