The Effect of Efudex (5-Fluorouracil) Treatment on Photoaged Skin


Efudex (5-fluorouracil) has been used as topical chemotherapy for the treatment of actinic
keratoses (AKs) since the 1950's. Through many years of use, Efudex has been deemed to be a
safe and effective therapy. It requires, however, a high level of patient compliance and is
known to cause a vigorous inflammatory reaction when actinic keratoses are treated. It has
the distinct advantage of identifying precancerous skin lesions not apparent on clinical
inspection or palpation. Following a course of Efudex to the face, patients have been noted
to have fewer signs of dermatoheliosis.

The investigators propose to determine if Efudex is associated with improvement of aging
skin in the setting of treating actinic keratoses. The researchers hope to demonstrate less
p53 staining following Efudex treatment. It is proposed that the skin improvements seen
following a course of Efudex are due to both reduction of actinic keratoses and impact on
photoaging. The researchers propose to quantify the effects of Efudex therapy on the
immunohistochemical staining properties of facial skin with respect to p53 and procollagen.
The hypothesis is that Efudex therapy will decrease p53 immunostaining thus providing
biochemical evidence to support this treatment in the reduction of actinic keratoses with
concomitant improvement of aging skin.


Inclusion Criteria:



- Age 50 or older of either gender.

- Patients must have clinical photoaging judged by rhytides, dyspigmentation,
poikiloderma, lentigines, skin thinning, and/or telangiectases.

- Subjects must be in generally good health and willing to undergo skin biopsies from
the face.

- Subjects must be willing and able to comply with the requirements of the protocol.

- You must live within a reasonable driving distance of Ann Arbor, Michigan, and/or be
able to attend all of the scheduled appointments during the study.

Exclusion Criteria:

- Oral retinoid therapy (such as Accutane) within two months of study entry.

- Topical retinoid, imiquimod, or diclofenac therapy within 2 months of study entry.

- 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.
