In the context where advanced cutaneous squamous cell carcinoma (cSCC) is currently a public health issue due to its increasing incidence and where its management is rapidly evolving, it is essential to characterize and monitor changes in therapeutic strategies for patients requiring systemic treatment with adjuvant/neoadjuvant or curative setting.

The overall objective of this study is to describe the long-term, real-life management of patients with cSCC requiring systemic therapy, including their clinical characteristics as well as treatment effectiveness and safety. To achieve this aim, the project is based on the establishment of a French national database of patients with cSCC receiving systemic therapy. This is a non-interventional multicenter study involving approximately 30 centers from the French Cutaneous Oncology Group (GCC), including a retrospective phase (from January 2020 for initiation of first-line systemic therapy) followed by a prospective phase.

Time perspective is Retrospective and Prospective
