Abstract

BACKGROUND: Keratinocyte carcinomas (KCs) are the most common cancers in the United States. Despite existing preventative strategies, their incidence continues to rise, highlighting a need for better intervention. The pulsed dye laser (PDL) has a myriad of medical indications but has not been studied in skin cancer prevention.

OBJECTIVE: The objective of this study was to assess the effect of PDL treatment on subsequent facial KC development.

MATERIALS AND METHODS: A retrospective cohort study was conducted on patients with a history of facial KC who received treatment at the Dermatology Laser and Cosmetic Center at Massachusetts General Hospital between 2000 and 2024.

RESULTS: Fifty-nine patients with a history of facial KC who received PDL treatment and 59 matched controls met inclusion criteria for the study. Subsequent facial KC was observed in 27.1% of PDL-treated patients, compared with 54.2% of controls (RR 0.50, p = .0047). After adjusting for age, sex, and skin type, control subjects remained at a higher risk for developing new facial KC compared with PDL-treated patients (HR 2.88, p = .0008).

CONCLUSION: These data suggest a potential association between PDL treatment and a reduced rate of subsequent facial KC development in patients with a history of KC.
