Our 10-year experience is reviewed of 27 cases of endobronchial metastasis diagnosed by bronchoscopy. Primary tumors were breast (15 cases), kidney, bladder, rectum and melanoma (two cases each), and stomach, gingiva, amygdala and penis (one case each). Their presentation was prior to primary neoplasm in two patients, simultaneously in three, and posterior in the remaining patients (mean 64 +/- 52 months). Half of patients also had extrathoracic metastasis. In cases of breast cancer systemic chemotherapy was administered and the median survival rate was 24 months, significantly longer than in the remaining group (3 months); in the later, symptomatic therapy predominated due to the common involvement of lung parenchyma and functional deterioration of patients.

Introduction: Endobronchial metastases (EBMs) are rare, with primary tumours predominantly of breast, renal, and colorectal origin. Bronchoscopy is the diagnostic gold standard, with histological confirmation through immunohistochemical study.
Cases: We presented three cases of EBMs, one secondary to colorectal cancer and two associated with renal tumours.

Background Early staging of lung carcinoma (CA) is pivotal in planning the treatment. Lymph node metastasis can be detected by imaging and invasive procedures. The 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) is an emerging noninvasive imaging modality in detecting nodal metastasis.

A man in his 60s, who had undergone surgery for rectal cancer, liver metastases, and lung metastasis, had a past history of myocardial infarction and ventricular fibrillation with reduced cardiac functions. He was referred to our department because of a pulmonary nodule shadow in the S2 right upper lobe and a bronchial cast shadow along the B2 bronchus. Robot-assisted thoracoscopic right S2 segmentectomy was performed and intraoperative bronchoscopy revealed a polyp-like tumor within B2a.

Objective: Endobronchial ultrasound-guided transbronchial needle aspiration is a vital tool for mediastinal and hilar lymph node staging in patients with lung cancer. Despite its high diagnostic performance and safety, it has a limited negative predictive value. Our objective was to evaluate the diagnostic performance of deep learning-based prediction of lung cancer lymph node metastases using convolutional neural networks developed from automatically extracted images of endobronchial ultrasound videos without supervision of the lymph node location.
