Veterans with a history of two or more keratinocyte carcinomas (skin cancers), with at least one on the face or ears (median age 70 years, 98% male, 99% White)

Study Design

Randomized controlled trial with quadruple blinding

Intervention 

  • 5-fluorouracil 5% topical cream

Setting

National

N

932

Response Rate

97.7% (932 of 954 initially enrolled)

Recruitment Method

Two recruitment strategies were employed:

  • Site coordinators reviewed medical records of patients scheduled for Dermatology Clinic appointments and assessed their electronic medical records for eligibility. The Site Investigator approached potentially eligible patients to speak about the trial. Interested patients were given a more detailed overview of the trial and consent for participation was obtained.
  • Request a comprehensive query of all patients who may have had two or more skin cancers in the prior five years was requested of each medical center. Study Coordinators mailed a recruitment letter to those potential participants and followed up with a phone call within two weeks.

Compensation

$20 - 40 per study visit to cover cost of gas and travel expenses

Data Collected

  • Time to first occurrence of a surgically treated primary keratinocyte carcinoma
  • Histopathologic specimens
  • Photographs to document reactions to skin cream
  • Self-reported symptoms/adverse effects of skin cream

Data Collection Methods

  • Assessment by dermatologist
  • Nurse interview (in person and by phone)
  • Review of medical record
  • Questionnaires
