Figure 2. Pol ι expression correlates with poor prognosis in human ESCC.

Figure 2

A. immunohistochemical staining of Pol ι in 170 tumor tissue samples (100×), a: Negative expression; b, Low expression; c, Moderate expression; d, High expression. B. survival analysis based on the expression level of Pol ι. The groups were ranked according to the Pol ι staining intensity. The percentages of overall survival in low Pol ι expression (A, a-b) was significantly higher than that of patients with high Pol ι expression (A, c-d) (p=0.031).
