In most cases, these malignancies arise in the head and neck area, and they can be treated with locoregional therapies. A minority of cases require systemic therapy. Currently, Sonic Hedgehog inhibitors (i.e., vismodegib and sonidegib) have been approved for advanced BCC, while the PD-1 checkpoint inhibitor cemiplimab has been approved as a first-line treatment for cSCC and as a second-line treatment for BCC. Nevertheless, there is a clinical need for an effective and safe systemic therapies for advanced synchronous (syn) BCC/cSCC not amenable to local treatments. International guidelines do not provide specific recommendations for patients affected by this condition, and no case reports on the full-dose association of these medications have been previously reported. Here, we present the cases of two elderly patients affected by synBCC/cSCC of the head and neck, who received combined therapy with cemiplimab and sonidegib at full dose and standard schedule, achieving remarkable clinical benefit and long-term responses, without major adverse events. The instance of a feasible treatment for patients with advanced synBCC/cSCC will become increasingly frequent with the advancement of life expectancy in the global population, and the synergistic activity of targeted therapies and immunotherapy—administered either in association or sequentially—deserves to be further explored.  \nKEYWORDS  \ncutaneous squamous ce","cbCaihscYr52j23J","https://ap.wps.com/l/cbCaihscYr52j23J","pdf",8962928,"English","# Introduction\n## Background on non-melanoma skin cancers\n## Risk factors and epidemiology\n# Case report summary\n## Combined full-dose cemiplimab and sonidegib therapy\n## Clinical outcomes and safety signals\n# Discussion and outlook\n## Need for evidence and future exploration","[{\"question\":\"What clinical problem does the article address?\",\"answer\":\"It addresses the need for effective and safe systemic therapy for advanced synchronous BCC/cSCC of the head and neck when patients are not suitable for local treatments and guidelines offer no specific recommendations.\"},{\"question\":\"How were cemiplimab and sonidegib used in the reported cases?\",\"answer\":\"Two elderly patients received combined therapy with cemiplimab and sonidegib at full dose and on the standard schedule.\"},{\"question\":\"What outcomes and adverse events were reported?\",\"answer\":\"The patients achieved remarkable clinical benefit with long-term responses, without major adverse events.\"}]","The association of cemiplimab plus sonidegib for synchronous cutaneous squamous cell carcinoma and basal cell carcinoma of the head and neck - Two case reports | PDF",1790270167,18]
