Summary
The goal of this clinical trial is to compare the effectiveness and safety of two treatments-cryotherapy and 5-Fluorouracil (5-FU)-for actinic keratosis, a common skin condition caused by long-term sun exposure. Cryotherapy is a treatment that uses extreme cold produced by liquid nitrogen to freeze and destroy abnormal cells, and 5-FU is a topical cream applied to the skin to treat lesions by interfering with cell growth. The main questions this trial aims to answer are:
* Which treatment, cryotherapy or 5-FU, is more effective in reducing the number of actinic keratosis lesions?
* What are the side effects associated with each treatment?
* How do these treatments impact patient satisfaction, cosmetic outcomes, and health-related quality of life?
Participants will:
* Undergo a baseline assessment where their demographics information such as age, sex, race, smoking status, and medical history are recorded, along with the number and severity of actinic keratosis lesions.
* Receive both cryotherapy and 5-FU, with each treatment applied to different areas of their body. The area of the body to receive each treatment is decided by a random process (like flipping a coin).
* Complete weekly surveys to monitor for side effects during and after the treatment period.
* Return to the clinic for follow-up assessments at 3 months and 12 months.
