摘要

A small proportion of cutaneous squamous cell carcinomas (CSCC) belongs to the group of advanced tumors that require adjuvant radiotherapy in addition to surgical resection. Despite the combination of these treatment modalities recurrences and distant metastases are not uncommon and are difficult to treat. The immuno-oncological medicament cemiplimab (monoclonal antibody against programmed cell death 1 protein, PD‑1 receptor) has been approved for a long time for the treatment in an unresectable situation (advanced or metastatic CSCC). The central objective of the C‑POST trial was to assess the effectiveness and safety of cemiplimab as adjuvant therapy in comparison to placebo in patients with resected high-risk CSCC after conclusion of postoperative radiotherapy. The results led to approval of cemiplimab in Germany for this group of patients.
