Elevated carcinoembryonic antigen and bronchial obstruction caused by a rotten vegetable leaf mimic lung cancer: A case report

Abstract

Tracheobronchial foreign body aspiration is a potentially risky medical event, associating with clinical manifestations varying from acute respiratory distress, to chronic pulmonary infections, even death. 1 Notably, accidental foreign body aspirations in children and adults with normal bronchial system are relatively uncommon occurrences, 2 which can develop with or without the presence of obvious incentives. Therefore, the condition often requires early detection and rapid intervention to improve respiratory symptoms and prevent major morbidity. 1,2

New insights into the diagnostic characteristics and clinical application of serum biomarkers for lung cancer, and human epididymis protein 4 as a new biomarker?

“…CEA is considered a biomarker for SCLC and adenocarcinoma (AD) of the lung [29], and serum CEA is elevated in many types of cancers mostly in AD [30,31]. CEA is also increased in other types of non-cancerous diseases or other conditions [11,32]. Our results showed that high levels of CEA were observed in both NSCLC (which includes AD and SCC) and SCLC (Figures 1, 2A, 2B).…”
