Remote afterloading high-dose-rate brachytherapy (RAHDRB) was used endobronchially for the management of malignant airway obstruction in 82 patients, 72 of whom had primary disease in the lung. Treatment was palliative (n = 58) or definitive (n = 24). The extent of airway compromise was determined at bronchoscopy and with symptoms of hemoptysis, dyspnea, or cough or with radiographic evidence of atelectasis. RAHDRB doses were 1,000-4,700 cGy in one to five fractions. External beam radiation was used in previously unirradiated patients. A substantial reduction ,N airway disease and an improvement in symptoms were seen in 82% of patients. Obstruction scores showed an overall 74% improvement. Complications occurred in only 10 patients (two of whom died). Median survival was short (palliative group, 5 months; definitive group, 12 months); however, symptoms remained palliated in 62 patients (76%) until death or the last follow-up examination. RAHDRB is effective and can be applied with equal success in all patients with malignant airway obstruction, even those whose disease has recurred after external beam irradiation.
