Acitretin in Preventing Skin Cancers in Patients With Previously Treated Skin Cancers Who Have Undergone Organ Transplantation
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of acitretin may be an effective way to prevent the recurrence or further development of skin cancer.
PURPOSE: Randomized clinical trial to study the effectiveness of acitretin in preventing skin cancers in patients with at least two previously treated skin cancers who have undergone organ transplantation.
|Study Design:||Allocation: Randomized
Primary Purpose: Prevention
|Official Title:||Chemoprevention Trial of Acitretin Versus Placebo in Solid Organ Transplant Recipients With Multiple Prior Treated Skin Cancers|
|Study Start Date:||May 2000|
|Primary Completion Date:||February 2003 (Final data collection date for primary outcome measure)|
- Determine the chemopreventive efficacy of acitretin in immunosuppressed solid organ transplant recipients with a history of multiple previous basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) skin cancer resections.
- Evaluate human papillomavirus (HPV) as a possible etiologic cofactor in the development of cutaneous epidermal dysplasia/carcinoma from skin tissues of these patients.
- Determine the effect of acitretin on potential surrogate endpoint biomarkers and HPV DNA in normal (sun protected), sun-exposed, and dysplastic and carcinoma (SCC/BCC) skin specimens.
OUTLINE: This is a randomized study. Patients are stratified according to age (at least 18 to under 50 vs 50 to 59 vs 60 to 69 vs 70 and over), number of prior skin cancers in past 5 years (2 vs 3 vs at least 4), time since most recent skin cancer occurrence (less than 12 months vs at least 12 months), sunburn susceptibility (none vs moderate vs high), visible skin damage (mild vs moderate vs severe).
Patients receive either oral acitretin or placebo daily for 2 years. Skin biopsies are obtained at 1 year from normal areas and from any areas with skin cancer for genetic studies.
Patients are followed every 6 months.
PROJECTED ACCRUAL: A total of 110 patients will be accrued for this study within 4-5 years.
