 (1) Roentgen signs useful in differentiating m from sm cancer of the esophagus include the degree of elevation for an elevated lesion, and marginal filling defect, double delineation sign, marginal elevation as well as the size of the lesion for a depressed or flat lesion.

 (2) Differentiation between ep and mm cancer is almost impossible with en-face view. Profile view, however, gives a clue to differentiating these two con-ditions, especially when the esophageal wall is well distended.

 (3) Diagnostic criteria for ep cancer should be defined based on clinically confirmed evidences.
