To determine the incidence of endobronquial metastases in a National Referral Thoracic Oncology Service.
We reviewed 5 years of bronchoscopic procedures. We only included patients where endobronchial metastases were suspected. Information was registered with respect to the primary tumor, symptoms, X ray studies, and location of endobronquial lesion, technique for obtaining samples, diagnosis and decision for surgical intervention.
From May 1999 to December 2004, 1735 bronchoscopic studies were practiced, of these 127 were done to determine lung metastases from extrathoracic tumors. In 41 patients bronchoscopic findings consisted of tumor in 21 cases, mucosal infiltration 16 cases and extrinsic compression 4 cases. The most frequent symptom was cough and the radiologic abnormality was presence of a mass. The primary tumor according to frecuency was breast, kidney and larynx. The majority of lesions were in the right bronchial tree. Endobronchial biopsy was positive in 37.5%, cytology brushing 25% and bronchial washing in 10%. Combination of the three techniques was diagnostic in 34.1%, increasing to 60% when other methods were utilized. Five patients underwent resection of the lesion.
Endobronquial metastases are associated with advanced metastatic disease and bronchoscopy is useful in establishing the diagnosis and determining treatment in selected cases.
Provide better quality of life in patients with endobronquial metastatic disease by improving treatment options.
