Comparison of therapeutic agents' short‐term effects on facial and scalp actinic keratosis: A network meta‐analysis

Abstract

AbstractBackgroundCare for actinic keratosis (AK) can be improved with more knowledge on the relative of effect of indicated therapies.ObjectivesUsing network meta‐analyses, we quantitatively determined the comparative “short‐term” effects of interventions in adults with facial and scalp AK.MethodsOn February 28, 2023, evidence from the peer‐reviewed literature was systematically obtained from OVID, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov. We analyzed data from studies published in English, of a trial design, and investigating the effect of an actinic keratosis monotherapy. Patient complete clearance, patient partial clearance or lesion‐specific clearance across adults were analyzed at 8–12 weeks after therapy. Patient complete clearance pertained to proportion of participants who experienced complete clearance of actinic keratosis lesions; patient partial clearance corresponded to percentage of subjects who achieved at least 75% clearance of actinic keratosis lesions; lesion‐specific clearance represented the percentage of all lesions that were cleared. In the main (i.e., base) analyses, nodes were analyzed only at the level of the agent.ResultsData from a total of 84 studies were used—across which 22 active agents were identified. Estimates of interventions' surface under the cumulative ranking curve rankings and (pairwise) relative effects were estimated. Across the three outcomes, fluorouracil 5% was ranked the most effective.ConclusionsOur work is the first to provide information on covariate‐adjusted relative effects of actinic keratosis therapies— including the more recently reported treatments—for the face and scalp; this knowledge may help physicians and patients make more informed decisions.
