Actinic Keratoses, Aging, Non-Melanoma Skin Cancer
Conditions
Brief summary
The purpose of this study is to determine if the Fractionated Laser Resurfacing (FLR) procedure can protect one forearm/wrist from precancerous actinic keratosis (AKs) as well as prevent skin cancer in older subjects with active AKs. This study builds on a similar study ongoing at the Dayton Veterans Administration dermatology clinic. This study is also testing if a photograph of the skin can be used to predict where the AKs and an skin cancers will form.
Interventions
A rejuvenating laser that makes tiny holes in the very superficial part of the skin.

Exclusion criteria
* More than 10 AKs on an extremity * AKs that are large (2-3+, hyperkeratotic grade 3 lesions) * AKs that are very thick (\>3 mm) * Medical history of diabetes * History of poor wound healing or scarring * Large tattoos that can interfere with study * Other serious health issues and other skin diseases that could interfere with the study * Recent (within 1 year) field therapies such as efudex cream or PDT to forearms/wrists. * Planning to leave region in next 5 years * Subjects with allergies to xylocaine will be excluded if they need this topical anesthetic.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in the number of actinic keratosis due to FLR treatment. | Up to 5 years | Investigator will assess the number of actinic keratosis on both forearms at each visit. |
| Change from baseline in the number of non-melanoma skin cancers due to FLR treatment. | Up to 5 years | Investigator will assess the number of actinic keratosis on both forearms at each visit. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Skin dysplasia change, in regards to actinic keratosis, from baseline due to FLR treatment. | Up to 5 years | Investigator will use the scattering patterns of light to assess the number of actinic keratosis on both forearms at each visit. |
| Skin dysplasia change, in regards to non-melanoma skin cancer, from baseline due to FLR treatment. | Up to 5 years | Investigator will use the scattering patterns of light to assess the number of actinic keratosis on both forearms at each visit. |
