ABSTRACT：The lungs are the most common sites of metastases from non- pulmonarymalignancies. Endobronchial metastases are rareand have no specificity in clinical manifestations，thus being prone to misdiagnosis and delayed treatment.The common tumors asociated with endobronchial metastasis are renal，breast，and colorectal cancers.This article reported one case of postoperative rectal cancer with endobronchial and lung metastases，which was relieved by high-frequency electrocautery ablationvia bronchoscope，chemotherapy，and targeted drugs，aiming to provide a reference for clinical diagnosis and treatment.

Key words：rectal cancer；endobronchial metastasis；bronchoscopy
