Advanced Cutaneous Squamous Cell Carcinoma (CSCC)

Non-melanoma skin cancers (NMSCs) are responsible for 90% of skin cancers in the United Kingdom (UK)1. Cutaneous squamous cell carcinoma (CSCC), a type of non-melanoma skin cancer (NMSC), accounts for approximately 23% of all NMSC cases in the UK and is the cause of 75% of NMSC deaths1-4. Primary CSCCs are typically curable with surgery and/or radiotherapy, however approximately 5% of all CSCCs will advance locally to other areas of the body, or spread5-7.

Advanced CSCC is classified as locally advanced and metastatic, including locoregional metastatic or distant metastatic CSCC8. Advanced disease is typically associated with a poor prognosis8.

Unmet CSCC Needs

Advanced CSCC causes significant morbidity and reduced quality of life due to scarring, disfigurement and aesthetic complications and functional loss9,10,11. When disfigurement is experienced, patients may also struggle with physical and psychosocial issues11. Surgery and/or radiotherapy may be ruled out when patients are likely to face unacceptable complications, morbidity or deformity post-treatment8,12. Rates of metastatic disease in recurrent CSCC vary from 25-45% depending on location of the tumour, with higher rates seen in the head and neck area, including in particular the ear and lip13.

There have historically been limited options for patients unable or unwilling to undergo local treatments12,14. A retrospective study conducted in 2018 showed that 59% of patients diagnosed with locally advanced CSCC and were found ineligible for curative surgery and/or radiotherapy remained untreated15.

Evolving Treatment Landscape

Alternative treatment approaches are required in advanced CSCC when surgery and/or radiotherapy is deemed to be non-curative or would result in disfigurement and loss of function16-18. Patients who are ineligible for curative local treatments may have historically received unlicensed chemotherapy typically associated with short lived responses or best supportive/palliative care19. Studies have demonstrated a median overall survival of 8 – 13 months for patients with locally advanced or metastatic CSCC who are not candidates for curative surgery or radiation20-28.

Within UK clinical practice guidelines, a specialist skin multi-disciplinary team (SSMDT) review of locally advanced and metastatic CSCC presentations is a key recommendation29-32. In the UK, MDT approaches to cancer patient management have been shown to improve patient survival rates in other tumour types (colorectal, oesophageal and head and neck) and overall patient experience of their care33. European clinical practice guidelines further recommend that people with locally advanced or metastatic CSCC who are not candidates for curative surgery or curative radiotherapy should receive first-line treatment with an antibody that inhibits the PD-1/PD-L1 immune checkpoint pathway29.

Sanofi Genzyme Oncology is committed to the management of patients with advanced CSCC. LIBTAYO® ▼ (cemiplimab) is a PD-1 immune checkpoint inhibitor and as monotherapy is indicated for the treatment of adult patients with metastatic or locally advanced cutaneous squamous cell carcinoma (mCSCC or laCSCC) who are not candidates for curative surgery or curative radiation34

ASCENT Knowledge Hub

The ASCENT knowledge hub has been developed to provide on-demand, HCP-led education and content for the CSCC MDT, including oncologists, surgeons, dermatologists and clinical nurse specialists. The ASCENT knowledge hub aims to facilitate discussion around critical issues in CSCC and the unmet needs of advanced patients; bring together all stakeholders committed to the management of CSCC within a single community; define the optimal management of patients prescribed Libtayo and share real world experience of using Libtayo.
