Summary

This study invites 2,900 adults who had radiotherapy for non-melanoma skin cancer on the head or neck between 2020 and 2024 to a follow-up visit at least two years later. Participants will fill out a questionnaire about how the treated area looks and have their skin examined. The goal is to learn about cosmetic results and how often the cancer comes back, which may help improve future care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could provide real-world data to improve treatment guidelines for non-melanoma skin cancer.
What could go wrong
This is an observational study, not a trial testing a new treatment. It cannot prove cause and effect, and results may not apply to other countries or healthcare systems.

Who is studied

Adults aged 18 years or older with head and neck non-melanoma skin cancer (basal cell carcinoma or cutaneous squamous cell carcinoma) who received primary radiotherapy between 2020 and 2024 at five Danish oncology centres. Participants will be invited via the national digital mailbox (e-Boks) to attend a hospital follow-up visit at the centre where they received radiotherapy, at least two years after completion of treatment. The study represents a real-world national cohort within the Danish public health-care system.
