Keys to Diagnosis of Small and Minute Esophageal Cancer Including Diagnosis by Magnifying Endoscopy with Narrow Band Imaging
With the advent of endoscopic therapy, the treatment of superficial-type esophageal cancer has greatly changed. Even when this cancer is detected at an early stage, surgery, chemotherapy, or radiotherapy is required. For diagnosis of esophageal cancer in the early stages, it is necessary to enhance the conventional endoscopic examination through the use of esophageal iodine staining and narrow band imaging in patients at high risk of esophageal cancer. These high-risk patients include 1) men with smoking habits and/or excessive alcohol consumption, in particular those who exhibit alcohol-induced flushing; 2) patients with head and neck cancer; 3) patients with melanosis observed by upper gastrointestinal endoscopy; and 4) patients with a personal or family history of cancer.
