Management of advanced cSCC is challenging, and many available systemic medications have modest efficacy. Cemiplimab has demonstrated efficacy in the treatment of advanced cSCC in clinical trials, but real-world data are still limited. With the objective of evaluating the efficacy of cemiplimab in a real-world clinical setting, we conducted a prospective observational study of 13 patients with advanced cSCC. Six patients (46%) had locally advanced disease, while 7 (54%) had metastatic disease. A total of 8 patients (62%) responded to cemiplimab. Five (38%) showed a partial response, while 3 (23%) showed a complete response. Four patients with an initial partial response presented subsequent disease progression during follow-up. Six patients (46%) developed AEs, most of which were mild (G1). PFS was 5.9 months, with a median follow-up was 9 months. In conclusion, cemiplimab demonstrated its utility in the treatment of advanced cSCC, with acceptable response rates, a remarkable number of complete responses, and a very good safety profile. Resumen: El manejo del carcinoma de células escamosas cutáneo (cSCC) avanzado es complicado, siendo modesta la eficacia de muchos de los fármacos sistémicos disponibles. Cemiplimab ha demostrado su eficacia en el tratamiento del cSCC avanzado en ensayos clínicos, pero los datos del mundo real siguen siendo limitados. Con el objetivo de evaluar la eficacia de cemiplimab en un entorno clínico del mundo real, realizamos un estudio observacional prospectivo de 13 pacientes con cSCC avanzado. Seis pacientes (46%) tenían enfermedad localmente avanzada, mientras que 7 (54%) tenían enfermedad metastásica. Un total de 8 pacientes (62%) respondieron a cemiplimab, 5 (38%) mostraron una respuesta parcial y 3 (23%) mostraron una respuesta completa. Cuatro pacientes con respuesta parcial inicial presentaron una progresión de la enfermedad subsiguiente durante el seguimiento. Seis pacientes (46%) desarrollaron efectos secundarios, siendo leve la mayoría de los mismos (G1). La supervivencia libre de progresión fue de 5,9 meses, con un seguimiento medio de 9 meses. En conclusión, cemiplimab demostró su utilidad en el tratamiento del cSCC avanzado, con unas tasas de respuesta aceptables, un número destacable de respuestas completas y un perfil de seguridad muy bueno.

Introduction and Objectives: Vismodegib is the first selective Hedgehog inhibitor approved for the treatment of locally advanced and metastatic basal cell carcinoma (BCC). In this article, we describe our experience with the use of this drug to treat advanced and/or multiple BCCs at a cancer center over 5 years., Material and Methods: We analyzed the following variables: patient age and sex; tumor location, size, type, and characteristics; time since onset; primary or recurrent status; duration of treatment; response to treatment (complete, partial, stabilization, or absence of response); adverse effects; and recurrences., Results: We treated 22 patients, of whom 20 had locally advanced BCCs and 2 had metastatic BCCs with lymph node involvement. The treatment was administered over a mean of 11.8 months. Nine patients (41%) achieved complete response and 10 (45%) partial response. The disease was stabilized in 3 (14%). Two patients relapsed after a median of 21 months. The main adverse effects were dysgeusia, alopecia, and muscle cramps, all of which were mild. None of the patients developed squamous cell carcinoma in an area treated with vismodegib, although metatypical changes were observed after treatment., Conclusions: With a response rate of 96%, vismodegib is a safe and effective treatment for locally advanced BCC. Adverse effects are generally mild but they need to be taken into account owing to their high frequency., (Copyright © 2018 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.)
