Figure 3

Survival curve of patients after curative resection for esophageal squamous cell carcinoma (ESCC) according to the expression of KCC3. (a) Patients were classified into two groups: low grade expression of KCC3 ( ) and high grade expression of KCC3 ( ) in the main tumor (MT). (b) Patients were classified into two groups: the low grade expression of KCC3 ( ) and high grade expression of KCC3 ( ) in the cancer nest (CN). (c) Patients were classified into two groups based on comparisons of the KCC3 score: CC ≤ MT ( ) and CN > MT ( ) in the cancer nest (CN). (d) Patients were classified into two groups based on the expression of KCC3 in the invasive front of the tumor: negative ( ) and positive ( ). (e) Patients were classified into two groups: patients with CN > MT and invasive front positive ( ) and others ( ). : log-rank test.
