Effectiveness of Endoscopic Classification in Assessing Tumor Infiltration Depth and Capacity of Early Oesophageal Carcinoma

Guiyong Peng

Tumor infiltration and lymphatic metastasis are the most important factors determining the prognosis of digestive tract cancers. Hence, assessment of tumor infiltration and lymphatic metastasis at an early stage is of great significance for the appropriate selection of treatment in clinical practice. However, preoperative assessment of tumor infiltration and lymphatic metastasis at the early stage of digestive tract cancers is relatively difficult. Our previous research revealed that the intraluminal growth pattern can reflect the growth pattern inside of the esophageal wall of early esophageal carcinomas. Therefore, based on endoscopic and ultrasonographic observations, we proposed a new endoscopic classification system for early esophageal carcinoma.
