Supplementary Material for: Advanced Cutaneous Squamous Cell Carcinoma Is Associated with Suboptimal Initial Management in a Cohort of 109 Patients

Background: Little is known about the epidemiological characteristics of patients with advanced cutaneous squamous cell carcinoma (A-cSCC). Objective and Method: A retrospective study was conducted on a routine care cohort of 109 patients to identify the epidemiological factors associated with A-cSCC. Results: The median age was 83 years (IQR: 73.9–89.8), and the median ECOG was 1 (IQR: 1–2). Sixty percent of the patients had a history of cardiac disease and 22% had cognitive disorders. Seventy-four percent of patients were from rural/semi-rural areas (towns of Conclusion: A-cSCC is associated with incomplete initial treatment in an elderly and rural population with good general condition. We hypothesize that a lack of access to good dermatological expertise may have led to underestimation of the aggressiveness of cSCC and/or therapeutic mismanagement.
