The Role of Cemiplimab in Treating Locally Advanced Cutaneous SCC: A UK Single-Centre Experience and the Implications for Surgical Management
摘要
Although over 95% of patients presenting with cutaneous squamous cell carcinoma (cSCC) are cured with surgery or radiotherapy, a subset develop locally advanced disease and undergo major resection and reconstruction. This may constitute high-risk surgery with potential for prolonged recovery and no assurance of oncological, functional, or aesthetic satisfaction. Immune checkpoint inhibitors have shown promise in this setting. We report a single-center UK experience with cemiplimab for locally advanced cSCC and our surgical experience of operating on a cemiplimab patient cohort.
MethodsThis retrospective cohort study included all patients treated with cemiplimab for ≥ 3 months between November 2021 and May 2025. We report the objective response rate and describe operative findings and surgical outcomes for patients who progressed on treatment. We present our early experience and discuss patient selection.
ResultsIn total, 25 consecutive patients were included, with a median follow-up of 16 months. The median age was 79 years (range 48–90). The objective response rate was 64%, comprising 11 complete and five partial responses. The median time to clinical response was 3 weeks. Among the 20 patients with operable disease, three (15%) underwent surgical resection for progressive disease with no surgical complications attributable to earlier cemiplimab. In total, 85% of patients avoided surgical intervention. Grade ≥ 3 toxicity occurred in 12% of patients, with one treatment discontinuation.
DiscussionCemiplimab demonstrated robust activity in patients with advanced cSCC in this real-world population, with durable responses in long-term survivors. Salvage surgery appears feasible for patients with disease progression.
