Treatments of actinic cheilitis: a systematic review of the literature

Background: No large studies have defined the best treatment of actinic cheilitis. Methods: We conducted a systematic review to define the best therapies for actinic cheilitis in clinicalresponse and recurrences. Results: We first identified 444 papers, and 49 were finally considered, including 789 patients and 843treated areas. The following therapies were recorded in order of frequency: laser therapy, photodynamic therapy (PDT), 3% diclofenac in 2.5% hyaluronic acid, PDT 1 5% imiquimod, aminolevulinic acidelaser or methyl-aminolevulinic acidelaser, 5% imiquimod, fluorouracil, partial surgery, 0.015% ingenol mebutate,50% trichloroacetic acid, and laser 1 PDT. Concerning the primary outcome, complete clinical response was achieved in 76.5% of patients, and 10.2% had clinical recurrences. Partial surgery and laser therapy showed the highest complete response rates (14 of 14 [100%] and 244 of 260 [93.8%], respectively) with low recurrences. Only a limited number of patients were treated with other therapies, with the exception of PDT, with 68.9% complete responses and 12.6% of recurrences. Interestingly, when combined with 5% imiquimod, the efficacy of PDT was significantly enhanced. Limitations: Heterogeneity across studies. Conclusion: Laser therapy appears the best option among nonsurgical approaches for actinic cheilitis, and PDT showed higher efficacy when sequentially combined with 5% imiquimod. Larger studies are needed to confirm these data
