MIIP and neoplasm: As shown in Table 1, although the MIIP expression levels were not correlated with age, gender, tumor size, or TNM stage (P > 0.05), low expression of MIIP was significantly associated with a higher histological grade (P < 0.01) (WHO histological grade, Figure 7B–C) and distant metastasis (P < 0.05) (Table 1).
