Efficacy of anti-PD-1 on skin carcinomas and melanoma metastases in an Xeroderma Pigmentosum patient

Abstract

Xeroderma pigmentosum is an orphan disease of poor prognosis. We report one case of parallel efficacy with anti-PD-1 antibody on both melanoma and skin carcinoma in a xeroderma pigmentosum patient.

A 17-year old patient presented with metastatic melanoma and multiple non melanoma skin cancers. He was treated with pembrolizumab, a monoclonal anti-PD-1 antibody, at the dose of 2mg/Kg 3 weeks apart. Parallel therapeutic efficacy of anti-PD1 was observed in metastatic melanoma and skin carcinomas, and maintained at week 24.

This observation suggests anti-PD1 may be considered in patients with XP and metastatic melanoma as well as advanced non melanoma skin cancer.
