Clinical Study Of The Relationship Between Endoscopic Performance And Tongue Image In Different Stages Of Esophageal Cancer

Objective: The invasive, unpleasant and inconvenient nature of current diagnostic about esophagus cancer limits their application in clinical practice. There is a great need of novel non-invasive method for early esophagus cancer diagnosis. In the present study, we intend to determine whether the tongue pictures are suitable for early detection of esophagus cancer.Materials and methods: The study aimed to assess the probability of detecting early esophageal cancer using endoscopy in the training set consisted of tumor endoscopic stage and tongue picture. Ulteriorly,whether we may examine early esophagus cancer using tongue picture. Indirectly, the probability of distinguishing the infiltrative depth and the longitudinal diameter of esophagus cancer apply between tumor endoscopic stage and tongue picture.Results: The tongue color usually present the white light in the early patients of esophagus cancer, the liguliform and the sublingual-threads are normal, the coated tongue take on the thick white fur. The significant difference exist between the classification of mucosal color in endoscopy and the tongue color, the liguliform, the sublingual-threads, and the relation of the tongue color is the significance. The significance differences have between the classification of the surrounding mucosal lesions and the coated tongue in endoscopy, but the relation of that is weak. between the moss-like lesions and the coated tongue is significant difference, the relation of that is general. The significant difference is between the endoscopic stages and the filtration depth of cancer tissues, the vertical by carcinoma.Conclusion:The changes of tongue picture consider as a recent,invasive and clinical approach in detecting early esophagus cancer. The approach have greatly potential, and the esophagus cancer is found in the early stage of “T” and the infiltration depth of carcinoma as soon as possible by the changes of tongue pictures. What is said above may increase the chance of operation and the time and survival.
