title: Adjuvant treatment of proper endobronchial management in leiomyosarcoma.
abstract: Endobronchial metastasis of leiomyosarcoma is rare, but it can cause life-threatening complications, such as massive hemoptysis, respiratory failure or even death. The development of new endoscopic modalities allows for effective endobronchial management. We report three patients with endobronchial metastases from advanced leiomyosarcomas which caused bronchial obstruction. The bronchoscopic examinations revealed masses obstructing the left main bronchus in all three patients. After removing the endobronchial tumor via interventional bronchoscopy, there was symptomatic and radiologic improvement. Moreover, the patients were able to undergo additional palliative chemotherapy. Therefore, endobronchial management of endobronchial tumors should be considered in the treatment of endobronchial metastasis, even in patients with advanced malignancies.
