Along with preventive strategies for eradicating lung cancer, detection and localization of small early-stage lung tumors are crucial for obtaining better therapeutic results, stated Harubumi Kato, MD, PhD, Professor, Department of Surgery, Tokyo Medical University, Japan. As a thoracic surgeon with more than 30 years of experience in photodynamic medicine, he believes that early-stage lung tumors can be completely treated with local noninvasive endoscopic treatments such as photodynamic therapy (PDT). The goals of PDT in lung cancer are curative for early-stage superficial lung tumors; palliative for relieving the symptoms of anchored, obstructive, advanced lung tumors; and neoadjuvant for reducing the resection volume. In this article, Dr. Kato shares a backward glance at where PDT has come from and a forward glimpse at where it may be heading.
