[Preoperative photodynamic therapy for lung cancer]

In Japan, photodynamic therapy (PDT) for locally superficial hilar lung cancer is common and its indications have already been determined. In order to improve the survival rate for lung cancer patients, it is necessary to increase the number of operable cases and preserve pulmonary function, and it thus would be beneficial to reduce the extent of resection. In our institution, preoperative PDT has been employed as one option to reduce the extent of resection. Nineteen patients who were initially planned to undergo pneumonectomy underwent successful lobectomy. For multiple primary lung cancer lesions, combined use of PDT was carried out in 29 cases. For early-stage lung cancer, PDT was performed and for advanced lesions surgery was selected. These new options may contribute to the management of advanced lung cancer.
