Summary of "Update on the anti-programmed cell death-1 receptor antibodies in advanced cutaneous squamous-cell carcinoma."

Regarding the rising incidence and the not negligible mortality, the treatment of cutaneous squamous-cell carcinoma (cSCC) has a high clinical relevance. Immune checkpoint inhibitors (ICI), especially anti-programmed cell death-1 receptor (anti-PD-1) antibodies such as pembrolizumab and cemiplimab have shown promising results in phase 2 studies for patients with locally advanced and/or metastatic cSCC. We are presenting a review of the latest results in the treatment of cSCC with ICI. Patients with locally advanced or metastatic cSCC have been treated with cemiplimab 3 mg/kg every 2 weeks. For locally advanced cSCC, an objective response was observed in 44% of patients, 13% patients with a complete response and 31% with a partial response. For metastatic patients, the overall response rate was 49.2%. The approved dose for cemiplimab in the USA and Europe is 350 mg every three weeks. These ICI seem to achieve higher response rates compared with epidermal growth factor receptor (EGFR) inhibitors, with a durable response superior to both chemotherapy and EGFR inhibitors. The side effect profile of anti-PD-1 antibodies appears to be favorable compared to chemotherapy. In this way, PD-1 inhibitors are expected to become the new gold-standard treatment for patients with locally advanced and metastatic cSCC. This article is protected by copyright.

Medical and Biotech [MESH] Definitions

An inhibitory T-lymphocyte receptor that has specificity for CD274 ANTIGEN and PROGRAMMED CELL DEATH 1 LIGAND 2 PROTEIN. Signaling by the receptor limits T cell proliferation and INTERFERON GAMMA synthesis. The receptor also may play an essential role in the regulatory pathway that induces PERIPHERAL TOLERANCE.

A costimulatory B7 antigen that has specificity for the T-CELL receptor PROGRAMMED CELL DEATH 1 RECEPTOR. It is closely-related to CD274 antigen; however, its expression is restricted to DENDRITIC CELLS and activated MACROPHAGES.

An inhibitory B7 antigen that has specificity for the T-CELL receptor PROGRAMMED CELL DEATH 1 PROTEIN. CD274 antigen provides negative signals that control and inhibit T-cell responses and is found at higher than normal levels on tumor cells, suggesting its potential role in TUMOR IMMUNE EVASION.

An inhibitory B7 antigen that contains V-type and C2 type immunoglobulin domains. It has specificity for the T-CELL receptor PROGRAMMED CELL DEATH 1 PROTEIN and provides negative signals that control and inhibit T-cell responses. It is found at higher than normal levels on tumor cells, suggesting its potential role in TUMOR IMMUNE EVASION.

The decrease in the cell's ability to proliferate with the passing of time. Each cell is programmed for a certain number of cell divisions and at the end of that time proliferation halts. The cell enters a quiescent state after which it experiences CELL DEATH via the process of APOPTOSIS.
