Notes: Correlation between the parameters except “outcome” and “tumor recurrence” was based on the data from all the 231 patients. * at p<0.05 level, ** at p<0.01 level.

Abbreviations: ESCC, esophageal squamous cell carcinoma; DTCD, degree of tumor cell differentiation; LNM, lymph node metastasis; PP, percentage of positive tumor cells relative to the total number of tumor cells.
