Indications for PDT (Photodynamic Therapy) generally speaking include:

• Actinic Keratosis (AK):
  • in Asian patients few studies are available
  • One study enrolled 43 patients with 58 AK (located on the face)
  • 85% cleared after 1 treatment at 4 weeks follow-up.

• Bowen’s disease (Squamous-Cell Carcinoma in situ):
  • in a Singaporean study
  • 43 patients were recruited
  • lesions were located on the head and neck
  • average age was 71.4 years
  • biopsy confirmed
  • clearance reached 85.7% after one treatment
  • of the 11 who didn’t respond, 8 were immunocompromised (eg kidney transplants on ciclosporine)
