HpD and laser photoradiation therapy (PDT) was performed preoperatively in 15 cases of bronchial tumors with invasion, and the effectiveness of resectionnecessary and to extend the surgical indications of surgery was valuated. PDT improved the condition of inoperable cases to the point where surgery could be performed in 4 out of 5 cases and the extent of resection was reduced from pneumonectomy to lobectomy in 7 out of 10 cases. This methodology makes it possible to reduce the extent of resection in cases with poor pulmonary function and increase the surgical indication in cases with advanced bronchial lesions.
