Brief Summary:
Guidelines for photodynamic therapy (PDT) of actinic keratosis recommend pretreatment with curettage. The impact of curettage on the treatment effect is, however, not known. The present study aimed to evaluate whether daylight-PDT without curettage would reduce treatment effect compared to daylight-PDT with curettage.

Condition or disease Intervention/treatment Phase
Keratosis, Actinic Drug: No curettage Drug: Curettage Phase 4

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 25 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Photodynamic Therapy of Actinic Keratosis of the Face and Scalp With and Without Prior Curettage
Actual Study Start Date : June 1, 2017
Actual Primary Completion Date : December 20, 2017
Actual Study Completion Date : December 20, 2017

Arm Intervention/treatment
Experimental: PDT with no curettage Drug: No curettage
Standard PDT without curettage

Active Comparator: Standard PDT Drug: Curettage
Standard PDT




Primary Outcome Measures :
  1. Complete lesion response rate [ Time Frame: Treatment efficacy was evaluated 3 months after PDT ]
    Complete lesion response rate, was defined as the number of completely responding lesions divided by the total number of treated lesion in each field. Complete lesion response was defined as complete disappearance of the lesion both by palpation and visually.
