CSP #562 - The VA Keratinocyte Carcinoma Chemoprevention Trial

United States954 participantsStarted 2009-06-26

Plain-language summary

The main purpose of this study is to see if 5-fluorouracil (5-FU) skin cream can prevent the growth of new skin cancers on the face and ears. The cost of trying to prevent skin cancer will be compared to the usual cost of treating skin cancer. Participants are being asked to be a part of this study because the participants have been treated for two or more skin cancers within the past five (5) years. At least one of these cancers occurred on the face or ears. Having had two or more skins cancers in the past 5 years makes it likely that participants will develop additional skin cancers in the future. Exposure to ultraviolet radiation from the sun or artificial sources such as tanning beds is a major cause of basal cell and squamous cell carcinoma of the skin. Using lotions, creams, or gels that contain sunscreens can help protect the skin from premature aging and damage that may lead to skin cancer. The 5-FU skin cream used in this study is FDA-approved to treat some types of skin cancers and spots that might become skin cancer. However, 5-FU skin cream has never been studied to see if it can prevent skin cancer. This drug is not approved by the FDA for how it will be used in this study. In this study, one half of the patients will use the 5-FU cream and the other half will use a skin cream that looks identical to the 5-FU cream but does not have 5-FU or any other active drug in it. Approximately twelve VA medical centers will work together in this study. About one thousand (1000) patients will be in this study. The study is sponsored by the U.S. Department of Veterans Affairs Cooperative Studies Program.

Inclusion Criteria: * Veteran who is at high risk for developing skin cancer defined as 2 keratinocyte carcinomas in the past 5 years, at least one of which was located on the face or ears Exclusion Criteria: * Participants who are unable to speak English * Participants with KC at randomization * Participants currently using or having used field therapy for AKs on the face or ears in the past 3 years. The vast majority of these field treatments would have been with 5-FU cream. The investigators will allow recent use of therapies that are applied to individual AK lesions (e.g. cryotherapy), but not those that were used on an entire area (field) in the study treatment area Participants currently using or having used systemic 5-fluorouracil or oral capecitabine (Xeloda) within the past 3 years Participants with known allergy to sunscreen, triamcinolone and/or 5-fluorouracil. Exclusions 6-l0: The investigators will exclude the small proportion who get their KCs for special reasons other than ultraviolet radiation exposure (see list below), since that etiologic difference, which is associated with a prognostic difference, could be associated with a biologic difference in response to chemoprevention efforts. These will include: * Solid organ transplant recipients, such as renal, hepatic, or cardiac transplant patients * Individuals with genetic disorders associated with very high cancer risk such as: * basal cell nevus syndrome * erythrodysplasia verruciformis * xeroderma pigm…
