Resumen
Fecha de inicio: 23 de febrero de 1999
Fecha en la que se inscribió al primer participante.OBJECTIVES: I. Compare the efficacy (clinical and histologic evidence of regression) of topical tretinoin with or without systemic fenretinide in patients with dysplastic nevi with personal or family history of cutaneous melanoma. OUTLINE: This is a randomized, double-blind study. Patients are stratified according to personal history of cutaneous melanoma vs family history of cutaneous melanoma in at least 2 blood relatives. Patients are randomized to one of two treatment arms. Arm I: Patients receive topical tretinoin twice daily and oral fenretinide once a day for 6 months. Tretinoin is applied to one half of the back with the untreated side of the back serving as a matched control. Arm II: Patients receive topical tretinoin as in arm I twice daily and oral placebo once a day for 6 months. Treatment continues in both arms in the absence of disease progression or unacceptable toxicity. Patients are followed at 6 months. PROJECTED ACCRUAL: There will be 38 patients accrued for this study.
