This study looks at a new treatment called **Alpha DaRT-224** for people with a type of skin cancer known as **recurrent cutaneous squamous cell carcinoma (SCC)**. The treatment involves placing a special radioactive source directly into the tumor, which releases radiation to kill cancer cells. This study aims to see how effective and safe this treatment is for up to 86 participants. DaRT seeds stay in the tumor for 14-21 days.
Participants will be monitored for 6 months to see how well they respond to the treatment and how long the response lasts. The study will also check for any side effects from the treatment. To join, participants must have certain health conditions and meet specific requirements like tumor size and life expectancy.
- Duration: Monitored for up to 6 months after treatment.
- Visits: Regular check-ups to monitor response and side effects.
- Eligibility: Must have recurrent SCC and be unable to have surgery or standard radiation.
