NCT00121511

Brief Summary

The researchers propose that skin improvements may be seen following a course of Efudex, (5-fluorouracil), a FDA-approved topical therapy (applied directly to the skin). These improvements could be the result of both a reduction of actinic keratoses (small red horny growths or flesh-colored wartlike growths caused by overexposure to ultraviolet radiation or the sun) and improvement of sun-damaged skin. In addition, this research study is being done to determine if the expression of p53, a tumor suppressor gene (its activity stops the formation of tumors), is decreased following Efudex treatment. Mutations (abnormal changes) in the gene, called p53, are associated with a certain type of skin cancer. In addition, p53-mutated genes are known to exist in non-cancerous sun-damaged skin. Thus, the presence of p53 mutations may serve as a marker for both sun damage and an elevated risk of developing skin cancer.

Outcome Measures

Primary Outcomes (1)

  • Actinic Keratoses resolution and improvement in photoaging

Secondary Outcomes (2)

  • Changes in p53 immunostaining intensity will be used to assess response

  • Collagen production will be evaluated by Western blotting, immunohistology, and RT-PCR

  • Prior laser re-surfacing, chemical peels for actinic keratoses or aging skin.
  • Pregnant or nursing subjects.
  • Non-compliant subjects.
  • Subjects with a significant medical history or concurrent illness that the investigator feels is not safe for study participation.
  • Prior systemic treatment with 5-fluorouracil.
  • Known history of allergy to lidocaine (numbing medication), 5-fluoruracil, or any other known components of Efudex.
