Abstract
A patient with unresectable lung cancer who was treated by photoradiation using haematoporphyrin derivative and a low-energy argon dye laser was presented. The patient, roentgenographically occult and cytologically positive, had three polypoid tumours diagnosed as squamous cell carcinoma in the trachea and at the bifurcation of the right upper lobe bronchus. Two of the tumours responded completely after the first course of treatment, and the remaining lesion showed a complete response after the second course of treatment. The patient is apparently diseasefree 72 months after treatment. Photoradiation therapy may be a curative form of treatment in certain early-stage cases of lung cancer.
