Official title

Efficacy and Safety of Cryotherapy Versus 5-Fluorouracil in the Treatment of Actinic Keratosis: A Prospective, Randomized Controlled, Intra-Individual Trial

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
