title: [Photodynamic Therapy for Lung Cancer].
abstract: In Japan, Photodynamic therapy (PDT) is recommended as a treatment option for centrally located early-stage lung cancers (CLELCs). It is a minimally invasive treatment with excellent anti-tumor effects. The 2nd generation photosensitizer, talaporfin sodium has strong anti-tumor effects with much less photosensitivity than porfimer sodium. Moreover, the laser equipment is compact and portable, and talaporfin sodium is now the current mainstay of PDT for lung cancer. For successful PDT, accurate evaluation of tumor extent and bronchial invasion is crucial. Detailed examination of the tumor using autofluorescence bronchoscopy and endobronchial ultrasonography or optical coherence tomography is extremely useful before PDT. At present, PDT has become the 1st choice of treatment for CLELC in institutions with the necessary equipment. It can also be effective for advanced lung cancer causing tracheobronchial obstruction. With such advances in PDT for CLELC, we are expanding the indications of PDT for not only CLELC, but also peripheral type lung cancer.
