Predictors of squamous cell carcinoma in high-risk patients in the VATTC trial.

Invasive squamous cell carcinoma (SCC) of the skin is one of the most common cancers in the United States, with no proven means for prevention other than systemic retinoids, which have significant toxicity, and sunscreen. We sought to determine the risk factors for invasive SCC on the face or ears in a high-risk population comprising 1,131 veterans in the Veterans Affairs Topical Tretinoin Chemoprevention (VATTC) Trial. Participants were required to have been diagnosed with at least two keratinocyte carcinomas (KCs) in the 5 years prior to enrollment.

Predictors of basal cell carcinoma in high-risk patients in the VATTC (VA Topical Tretinoin Chemoprevention) trial.

Basal cell carcinoma (BCC) is the most common cancer in the United States today, and patients who have had one are likely to have multiple carcinomas over time. Predictors of new BCCs on the face and ears among those at very high risk have not been studied in detail. We sought to do so prospectively in the context of a 6-year trial.

Tretinoin and the prevention of keratinocyte carcinoma (Basal and squamous cell carcinoma of the skin): a veterans affairs randomized chemoprevention trial.

Keratinocyte carcinoma (KC) is the most common cancer in the United States, with no proven means for prevention other than systemic retinoids, which have significant toxicity, and sunscreen. Topical tretinoin has been used for KC chemoprevention, although this use is unproven. Hence, we conducted the randomized Veterans Affairs Topical Tretinoin Chemoprevention Trial of high-dose topical tretinoin for KC prevention.

The linear excisional wound: an improved model for human ex vivo wound epithelialization studies.

Background/purpose: Wound healing is a complex process that involves multiple intercellular and intracellular processes and extracellular interactions. Explanted human skin has been used as a model for the re-epithelialization phase of human wound healing. The currently used standard technique uses a circular punch biopsy tool to make the initial wound.

Personalizing dermatology: the future of genomic expression profiling to individualize dermatologic therapy.

At the start of the 21st century, the human genome project provided the scientific community with an enormous array of information as genetic blueprints. A landmark period, yet its potential contribution to medicine at the time was limited and unknown. However, with new technological advances, the benefits of identifying genomic profiles became apparent.
