Fluorescence photoradiation was performed to investigate localization of tumor using hematoporphyrin derivative (HpD) and krypton ion laser light in 35 cases of central type lung cancer. Fluorescence was recognized in all of 3 early stage cases and 29 of 32 cases of other stages of central type lung cancer. Nd-YAG laser vaporization was performed in 29 malignant and 6 benign lesions of the trachea and bronchus and improvement was obtained in 20 of 35 cases. Photoradiation therapy (PRT) with HpD and argon dye laser was performed in 53 cases of lung cancer. Complete tumor remission was obtained in 7 of 8 early stage central type lung cancer cases, which were inoperable or refused surgery, and partial remission was obtained in all other stage cases. The methcd was valuable to treat early stage central type lung cancer and also to reduce the extent of resection and to widen the indications of surgery.
