JOURNAL TITLE: Euroasian Journal of Hepato-Gastroenterology
CA 19-9 is used as a tumor marker in colon, pancreas, biliary, and gastric cancers. Laryngeal cancer is the most common malignant epithelial tumor among head and neck cancers and has no specific tumor marker.
A 66-year-old male patient had severe reflux symptoms during 5 years and had an isolated CA 19-9 elevation. Follow-up analysis revealed that he had larynx cancer and after laryngectomy, CA 19-9 levels decreased to normal range.
Currently, CA 19-9 is not a marker for malignancy. Laryngeal carcinoma has no specific tumor marker, but laryngeal squamous cell carcinoma may be manifested by elevated CA 19-9 levels.
