Brief Summary

Methyl aminolaevulinate photodynamic therapy (MAL-PDT) is advantageous in that it has few cosmetic side effects and minimises patient discomfort. However, its relatively low efficacy prevents its application to the treatment of actinic cheilitis(AC). Er:YAG ablative fractional laser (AFL) treatment removes the stratum corneum to increase MAL uptake and may improve efficacy. However, no studies have directly compared the efficacy of MAL-PDT with and without Er:YAG AFL in treating AC

Outcome Measures

Primary Outcomes (1)

  • Difference the efficacy between Er:YAG AFL-assisted MAL-PDT (Er:YAG AFL MAL-PDT) and standard MAL-PDT.

    Lesion response was classified as either complete (complete disappearance of the lesion) or incomplete (incomplete disappearance) on the basis of visual examination and palpation. The response of each lesion was clinically evaluated

    Efficacy was evaluated at 3 months and 12 months after treatment

Secondary Outcomes (1)

  • Difference of the cosmetic outcomes between Er:YAG AFL-assisted MAL-PDT (Er:YAG AFL MAL-PDT) and standard MAL-PDT.

    Cosmetic outcome was assessed by each investigator for all lesions that achieved a complete response at 12 months

Other Outcomes (1)

  • Difference of the recurrence rates and safety between Er:YAG AFL-assisted MAL-PDT (Er:YAG AFL MAL-PDT) and standard MAL-PDT

    within 12 months after both treatment

Study Arms (2)

Er:YAG AFL-PDT

EXPERIMENTAL

Eligible patients were successively randomised to receive treatment with a single session of Er:YAG AFL MAL-PDT or 2 sessions of MAL-PDT with a 1-week interval between sessions

Drug: Er:YAG AFL-PDT

MAL-PDT

ACTIVE COMPARATOR

Eligible patients were successively randomised to receive treatment with a single session of Er:YAG AFL MAL-PDT or 2 sessions of MAL-PDT with a 1-week interval between sessions

Drug: MAL-PDT

Interventions

Er:YAG AFL was performed with 350 µm ablation depth, level 1 coagulation, 22% treatment density, and a single pulse. MAL cream was then applied under occlusion for 3 hrs and illuminated with a red light-emitting diode light at 37 J/cm2.

Also known as: Er:YAG ablative fractional laser-assisted MAL-PDT
Er:YAG AFL-PDT

a 1-mm thick layer of MAL (16% Metvix® cream, PhotoCure ASA, Oslo, Norway) was applied to the lesion and to 5 mm of surrounding healthy tissue. The area was covered with an occlusive dressing (Tegaderm, 3M, Saint Paul, MN, US) for 3 hours, after which the remaining cream was removed with saline gauze, and the red fluorescence of porphyrins was visualized with Wood's light. Each treatment area was then separately illuminated with red light-emitting diode (LED) lamps (Aktilite CL128; Galderma, Bruchsal, Germany) with peak emission at 632 nm and total light dose of 37 J cm-2. Areas scheduled to receive MAL-PDT received the second treatment 7 days later.
