MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Photodamage refers to premature skin aging from long-term UV exposure. Topical fluorouracil cream, typically used in the treatment of actinic keratosis, has been suggested for use in treating photodamage due to clinical and histological findings. However, in our ad hoc secondary analysis of a large randomized clinical trial, a standard course of topical fluorouracil did not result in detectable improvement of photodamage.
MedicalResearch.com: What should clinicians and patients take away from your report?
Response: The primary strength in this study is a large sample size in a randomized clinical trial of participants with severe photodamage. Our finding may suggest a true lack of effect of topical fluorouracil on photodamage. However, it may also be attributable to limitations in current photoaging scales. Most photonumeric scales focus on rhytids; fluorouracil may impact other manifestations of photoaging due to its mechanisms of action.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Response: The development of photonumeric scales that include manifestations of photoaging other than rhytids, such as hyperpigmentation, lentigines, telangiectasias, and volume loss, should be considered.
