Abstract

Advanced cutaneous squamous cell carcinoma is a challenge to treat. Conventional systemic treatment options include chemotherapy and epidermal growth factor receptor-inhibitors. The aim of this study was to assess clinical outcomes with systemic treatments in advanced cutaneous squamous cell carcinoma. Patients receiving systemic treatment at the Tübingen Dermato-Oncology centre between 2007 and 2017 were identified (n = 59). Median age was 76 years (interquartile range (IQR) 71–80 years), 83.1% of patients were male, 72.9% had metastatic cutaneous squamous cell carcinoma, and 27.1% had unresectable locally advanced cutaneous squamous cell carcinoma. During median follow-up of 52 weeks (IQR 27–97 weeks), overall response rate was 14.3%, and disease control rate was 53.6%. Median progression-free survival was 15 weeks (IQR 8–42 weeks), and median overall survival was 52 weeks (IQR 27–97 weeks). Patients receiving chemoradiation vs chemotherapy alone showed better overall survival (hazard ratio 0.41, p = 0.014,) and progression-free survival (hazard ratio 0.42, p = 0.009); no differences were observed for metastatic cutaneous squamous cell carcinoma vs locally advanced cutaneous squamous cell carcinoma patients. Although chemotherapy and/or cetuximab showed limited outcomes in advanced cutaneous squamous cell carcinoma, such therapy may still be an option when anti-PD-1 treatment is contraindicated.
