Additionally, we performed immunohistochemical (IHC) staining of an EAC TMA ( n = 46) showing patients expressing ISG15 ( n = 40) showed a trend of correlation with poor OS ( P = 0.09) compared with nonexpressors ( n = 6; ~12% of all EACs) ( Figure 6, H and I , and Table 2 ), suggesting a critical role of ISG15 expression in EAC.
