Lasers for the Treatment of Nonmelanoma Skin Cancer: A Systematic Review of the Literature

Lasers may present an alternative treatment modality for the management of nonmelanoma skin cancer (NMSC).

To investigate lasers as a definitive treatment of NMSC.

A comprehensive search was performed on MEDLINE, the Cochrane Library, and the National Institutes of Health ( www.clinicaltrials.gov ). The Preferred Reporting Items for Systematic Reviews and Meta-Analysis was used to finalize a list of relevant literature studies evaluating the role of laser therapy for NMSC. Articles published through May 1, 2023, were included.

The authors identified 37 studies investigating nonablative and ablative lasers alone and in combination with other lasers, noninvasive imaging, and additional modalities for the treatment of basal cell carcinomas, 10 focusing on squamous cell carcinoma in situ and 3 focusing on the treatment of both basal and squamous cell carcinomas.

Although surgical management continues to be superior to laser therapy for the management of high-risk and cosmetically sensitive tumors, laser therapy may be an acceptable alternative for low-risk lesions on the trunk and extremities. However, further studies are needed to optimize parameters, determine maximal efficacy, and provide long-term follow-up before the adoption of laser therapy for NMSC into daily clinical practice.
