Abstract
It certainly falls within the aims and scope of any international or national laser society to help regulate the safe use of the laser or any other form of phototherapy, and the Japan Society for Laser Surgery and Medicine (JSLSM) is one of the longest-established laser societies in the world, with a large and active membership and annual meetings which are well-attended each year. The JSLSM maintains contacts within the Japanese Ministry of Health, Labour and Welfare, and has acted in an advisory capacity for many years. At the 2006 meeting of the JSLSM, new safety guidelines in various fields were adopted, including the very precise field of photodynamic therapy (PDT). The following is the set of JSLSM guidelines for the application of PDT for early stage lung cancer, which the author offers as a starting point for comments and discussion from interested international bodies.
