Filter by:RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. The use of celecoxib may be an effective way to prevent the development of basal cell carcinoma. PURPOSE: Randomized phase II trial to determine the effectiveness of celecoxib in preventing basal cell carcinoma in patients who have basal cell nevus syndrome.
RATIONALE: Photodynamic therapy uses light and drugs that make cancer cells more sensitive to light to kill tumor cells. Photosensitizing drugs such as HPPH are absorbed by cancer cells and, when exposed to light, become active and kill the cancer cells. PURPOSE: Phase I trial to study the effectiveness of photodynamic therapy with HPPH in treating patients who have basal cell skin cancer.
One-third of all malignancies in the United States (approximately one million cases diagnosed annually) are nonmelanoma skin cancer (NMSC). NMSC causes considerable morbidity, economic burden, facial deformity and at least 1,000 deaths annually. Prevention of these malignancies with a topical agent free of serious side effects would confer substantial public health benefit. Three hundred fifty thousand veterans were expected to develop NMSC in 1994. NMSC is one of the most common conditions requiring dermatologic care in the VA system. Topical tretinoin has been used extensively to treat photoaged skin. Retinoids administered orally in high doses appear to be effective in chemoprevention of nonmelanoma skin cancer but have unacceptable toxicity. In this study, 1131 patients with a recent history of squamous cell and/or basal cell carcinoma were enrolled at six participating centers over a four-year period and were randomly assigned to either 0.1% tretinoin cream or placebo. They were followed for a minimum of two years to determine if topical tretinoin is effective in reducing the risk of new occurrences.
This is a continuing study which evaluates the long-term safety and efficacy of oral acitretin in an open manner in the treatment of psoriasis, cutaneous disorders of keratinization, multiple basal cell carcinomas and other retinoid responsive diseases.
RATIONALE: Photodynamic therapy uses light and drugs that make cancer cells more sensitive to light to kill tumor cells. Photodynamic therapy using aminolevulinic acid cream may be effective in treating patients with skin cancer. PURPOSE: This randomized phase II trial is studying how well photodynamic therapy works in treating patients with skin cancer.
