Further study details as provided by Lithuanian University of Health Sciences:

Primary Outcome Measures:
  • Clinically cleared actinic keratosis with histological evaluation when clinically suspicious for relapse [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    All treated actinic keratoses evaluated by two investigators for clinical/histological relapse at months 1, 3, 6, 12, 24 after treatment


Secondary Outcome Measures:
  • Pain during the treatment [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Patients inform a present investigator about pain severity at the beginning, in the middle, at the end of the session and move a counter of visual analogue scale.

Arms Assigned Interventions
Active Comparator: Group I
Patients with actinic keratosis (AK) on the left and right sides of face/scalp region treated with photodynamic therapy using 20% 5-aminolevulinic acid.
Device: Photodynamic therapy with light dose of 70 J/cm2 using a broad-band red light source

Patients take part in intraindividual (left-right) comparison study when having at least 2 non-hyperkeratotic actinic keratoses (AK) on the left and right sides of the face/scalp.

Punch biopsies in 3.5 millimetres diameter performed to confirm the diagnosis of AK.

Patients randomized so that half of them would receive a light dose of 70J/cm2 as their first split face/scalp treatment on the left side. Photodynamic therapy with the light dose of 70 J/cm2 using a broad-band red light source (570-670 nm,Curelight®, PhotoCure, Oslo, Norway) and 20% 5-ALA. Treatment repeated twice with two weeks interval.

Active Comparator: Group II
Patients with actinic keratosis (AK) on the left and right sides of the face/scalp region treated with photodynamic therapy using 20% 5-aminolevulinic acid.
Procedure: Photodynamic therapy with 100J/cm2 light dose using a broad-band red light source

Patients take part in intraindividual (left-right) comparison study when having at least 2 non-hyperkeratotic actinic keratoses (AK) on the left and right sides of the face/scalp. Punch biopsies in 3.5 millimetres diameter performed to confirm the diagnosis of AK.

Patients randomized so that half of them would receive a light dose of 100J/cm2 as their first split face/scalp treatment on the left side. Photodynamic therapy with the light dose of 70 J/cm2 using a broad-band red light source (570-670 nm,Curelight®, PhotoCure, Oslo, Norway) and 20% 5-ALA.Treatment repeated twice with two weeks interval.


Detailed Description:

To determine and compare clinical and histological effectiveness of different (70 J/cm2 ir 100 J/cm2) light doses when treating actinic keratoses with photodynamic therapy.

To determine pain intensity during photodynamic therapy with visual analogue scale and factors influencing pain during the procedure.
