Cutaneous squamous cell carcinoma (cSCC) is the second most common form of skin cancer worldwide after basal cell carcinoma. It involves approximately 20% of all cutaneous malignancies and its incidence is still increasing. In 2020, nearly 15,000 cSCCs were reported in the Netherlands, of which approximately 50% concerned patients aged 75 years or older. UV radiation is the main risk factor for development of a cSCC, therefore the majority of cSCCs are localized to the sun-exposed skin in the head-neck region. cSCCs have a metastatic rate of 2.6-5% and recurrence rate of 1.9-3.7%, with rates increasing in high-risk cSCCs. The increasing incidence, advanced age, the (often) high-risk localization in the head-neck area (given functional and cosmetic importance) and the possible high risk of metastasis result in complex care, especially in stage T2 to T4 cSCCs, also known as high-risk cSCCs.~Patient-reported outcomes and health related quality of life (HRQoL) are important outcomes in the care for high-risk cSCCs in the head-neck region (HNcSCCs). Previous research is limited regarding the impact of cSCCs on QoL in patients with high-risk HNcSCCs , as is research on decision conflicts in the choice of treatment. The PROFILES registry (Arts, 2019) investigated QoL and satisfaction with care in 215 patients with keratinocyte carcinomas in the head-neck region. However, the majority of the patients had basal cell carcinoma (81%); only 23 patients had cSCC. Besides, no distinction was made in high or low risk cSCC. Finally, quality of life and patient satisfaction questionnaires were not administered until at least one year after diagnosis.~Other studies of QoL in cSCC patients do not distinguish stage and/or location of the tumor, involve small study populations, or only use oncological questionnaires rather than disease-specific questionnaires.~In conclusion, there is little scientific research on health related quality of life, decision conflicts in the choice of treatment and satisfaction with care in specific patients with high-risk HNcSCCs.
Patient reported outcomes in patients with high-risk cutaneous squamous cell carcinoma in the head-neck region are an important part of the complex care for these patients. Health-related quality of life, decision conflicts in the choice of treatment and satisfaction with care have not yet been sufficiently studied in this patient group.
