RESUMO
BACKGROUND: Despite the superior efficacy of topical therapies for the treatment of actinic keratoses in clinical trials, cryosurgery remains a frequent treatment modality in clinical practice. Little is known about patients' experience of real-world use of topical therapy. OBJECTIVE: To determine the real-world effectiveness and tolerability of 5-fluorouracil and imiquimod in the treatment of actinic keratoses. METHODS: A phone survey and chart review was conducted among 51 patients prescribed 5-fluorouracil (N = 27) or imiquimod (N = 24) for actinic keratoses. RESULTS: Six patients (22%) in the 5-fluorouracil group and five patients (21%) in the imiquimod group reported severe local skin reactions, and three patients in both groups (11% and 13%, respectively) were unwilling to use the respective topical therapies again. Patients in the 5-fluorouracil group had, on average, 3.3 fewer cryosurgery spot treatments following topical treatment. Patients in the imiquimod group averaged 2.0 fewer spot treatments. LIMITATIONS: While this study provides information on real-world experiences, patients' responses were limited by the ability to recall treatment and potential adverse effects. CONCLUSION: High rates of skin reactions, prolonged discomfort, and the continued need for procedural treatments may make patients less willing to use topical 5-fluorouracil or imiquimod for actinic keratoses.
