TLE1 and neoplasm: In subgroup survival analyses, more than half of the subgroups (namely, female, male, age ≤ 60 years, age > 60 years, non-diabetic, elevated CA19-9, small tumor size (≤ 4 cm), head and non-head tumor locations, G3–G4 tumor grade, absence and presence of perineural invasion, absent vascular invasion, T3 stage, N0 stage, and N1 stage, and TLE1 expression) were prognostic factors in univariate analyses (P < 0.05; Table 3).
