BACKGROUND: Squamous cell carcinoma (SCC) is the second-most common form of non-melanoma skin cancer (NMSC). OBJECTIVE: To provide guidance to Canadian health care practitioners regarding management of SCCs. METHODS: Literature searches and development of graded recommendations were carried out as discussed in the accompanying introduction (chapter 1 of the NMSC guidelines). RESULTS: SCCs are sometimes confined to the epidermis, but they can also invade nearby tissues and, in some cases, metastasize to neighbouring lymph nodes or other organs. This chapter discusses the natural history, staging, prognosis, and management of SCC--a tumour type that is less common but typically more aggressive than BCC. For this reason, margin control is strongly preferred in treating SCCs. CONCLUSIONS: Although approaches such as cryosurgery and radiation therapy may be considered for some patients, surgical excision--sometimes coupled with radiation--remains the cornerstone of SCC management. Patients with high-risk SCC may also be considered for referral to an appropriate multidisciplinary clinic.
