Cemiplimab in Ultra-Octogenarian Patients with Cutaneous Squamous Cell Carcinoma: The Real-Life Experience of a...

The incidence of cutaneous squamous cell carcinoma (cSCC) is rapidly increasing, paralleling the aging of the population. cSCC predominantly affects chronically sun-exposed areas, such as the head and neck region. At our tertiary center, a multidisciplinary approach to non-melanoma skin cancer is provided for locally advanced cSCC.

We retrospectively revised all patients with locally advanced/metastatic cSCC treated with anti-PD1 antibody (Cemiplimab) at our Institution from January 2020 to March 2023 (minimum follow-up of 4 months on treatment).

Overall, we consecutively treated 20 ultra-octogenarian patients, of whom 15 were males and 5 were females (median age: 86.9 years). Despite age, a median number of concomitant drugs, and comorbidities, efficacy, and safety were superimposable with the available literature. No patients reported treatment-related adverse events of grade 3 or higher. Grade 2 adverse events were reported in 25% of patients. Overall, the response rate was 65%, with 50% partial responses and 20% long-lasting stable disease. The median duration of response was 14 months. The G8 elderly score was assessed in all patients, and the median score was 12 (range 9-14).

Among ultra-octogenarian patients, a clinical benefit from Cemiplimab was obtained in most, including tumor shrinkage and pain relief. Cemiplimab confirmed its effectiveness in elderly patients in a real-life setting, with no new safety concerns.
