Abstract
Background: There is limited direct comparative data on imiquimod versus cryotherapy to treat actinic keratoses. Objective: Compare lesion response through 12 months post-initial treatment. Methods: Patients with ≥10 lesions on the face or scalp were randomized to cryotherapy (up to 10 lesions per session, up to 4 sessions, every 3 months) or imiquimod (3-times-per-week for 3-4 weeks, up to 2 courses) with repeat treatment depending on response. Results: In 36 patients assigned to cryotherapy and 35 to imiquimod, lesion complete response rates were 85.0 percent (306/360) and 66.9 percent (234/350) for cryotherapy and imiquimod, respectively (P<0.0002). For completely cleared lesions, global ..
