Staging criteria for carcinoma of the esophagus have been proposed. However, they do not provide excellent prognostic stratification, and are not simple to use.
In this study, researchers from Japan established simple and appropriate criteria to determine the clinical stage, with a strict prognostic stratification, for carcinoma of the esophagus.
The team included 260 patients with esophageal carcinoma, who had undergone esophagectomy and reconstruction.
They classified the patients according to their own staging criteria, SN classification.

The researchers then investigated clinicopathologic features and survival rates.
The team found that 1-, 3, and 5-year survival rates in patients who were classified as SN stage A were 100%, 95%, and 89%, respectively.
In patients with stage B, the team found that survival rates were 94%, 72%, and 62%.
In patients in stage C were survival rates were 72%, 34%, and 31%, and in patients with stage D, the rates were 32%, 9%, and 9%.
Analyses showed statistically significant differences between stages.
Dr Tadahiro Nozoe's team concluded, "Devised staging criteria for esophageal carcinoma providing an excellent stratification of disease has been established".
"The criteria are quite simple and convenient for physicians to apply clinically in determining the stage of esophageal carcinoma".
