PURPOSE: Aim our study was to investigate the frequency and localization of endobronchial metastases in patients undergoing bronchoscopy at Tertiary University Center.
METHODS: We retrospectively evaluated the data of all patients undergoing bronchoscopy in the years 2002-2010. The patients with proven endobronchial metastases were further characterized in terms of primary tumor, site of endobronchial metastases, intervals between the primary tumor and occurence of endobronchial metastasis, treatment and survival.
RESULTS: Between 2002-2010 6086 bronchoscopies were performed. In 31 patients endobronchial metastases were diagnosed (0.51% of patients). The most frequent sites of primary tumor were carcinoma of the breast (8 cases), renal carcinoma (5 cases), colorectal carcinoma (5 cases), carcinoma of the uterus (3 cases) and carcinoma of the thymus (3 cases). Most frequent localization of endobronchial metastasis were segmental bronchi (14 cases), followed by main bronchi (7 cases) and lower lobe bronchi (6 cases).
CONCLUSIONS: Endobronchial metastases represent a rare bronchoscopical findings which can be misdiagnosed as primary lung tumor.
CLINICAL IMPLICATIONS: Possibility of endobronchial metastasis has to be taken into account in all patients with previous extrapulmonary malignancy.
