For the staging of esophageal cancer, it not only depends on the T stage, but also on the N and M stages. If we are just considering the T stage, it is T3. If there are no N0 and M0 stages, it is relatively early and surgery can be considered. However, if looking only at T3 and the N stage involves lymph node involvement (N1, N2, or N3), with regional or distant lymph node metastasis, then the staging of the esophageal cancer is relatively late. Furthermore, if there is an M stage, which indicates the presence of distant organ metastasis, then it is classified as advanced stage. Therefore, the T stage alone for esophageal cancer does not determine whether it is early, intermediate, or late stage. It is necessary to look in conjunction with the N and M stages to determine the overall staging.
