title: Successful treatment of refractory bronchorrhea by inhaled indomethacin in two patients with bronchioloalveolar carcinoma.
abstract: Bronchorrhea in patients with bronchioloalveolar carcinoma is not uncommon. However, to our knowledge, an effective treatment for bronchorrhea in these patients has not been established. Recently, we have confirmed the efficacy of inhaled indomethacin in severe refractory bronchorrhea in comparison to that of other medications in two patients with bronchioloalveolar carcinoma. Despite the administration of a macrolide and corticosteroid, sputum volume increased to 700 mL/d in case 1 and to 200 mL/d in case 2 and hypoxemia and dyspnea deteriorated. Within a few days after the initiation of treatment with inhaled nebulized indomethacin (75 mg/d), sputum volume started to decrease and was controlled to < 100 mL/d, associated with alleviation of dyspnea and hypoxemia. To our knowledge, this is the first report of successfully treated refractory bronchorrhea associated with bronchioloalveolar carcinoma by inhaled indomethacin, resulting in markedly reduced sputum volume, improved quality of life, and prolonged survival.
