Abstract
Among 43cases of lung cancer treated by endoscopic laser therapy since 1987, we analyzed the effect of endoscopic photodynamic therapy (PDT) on 7cases of a hilar recurence after operation. PDT was performed by laser irradiation using the gold vaper laser or excimer dye laser after hematoporphyrin (HPDII) infusion.
All of these 7 cases had hemoptysis at the first medical examination, and diagnosed as a hilar advanced recurrence of lung cancer. PDT was selected and performed for these cases, as an operation could not be undergone because of the patients age, poor respiratory function, or patient's refusal. All cases demonstrated marked improvement of obstructive pneumonia caused by bronchial stenosis in a lilac lesion. they survived for 19 months (average) after PDT
(Summary) Endoscopic photodynamic therapy appears to be effective for the treatment of a hilar recurrence of lung cancer after operation, and especially improves quality of life and survival of the patient who has no indication for an operation because of aging or poor respiratory function.
