Biomarker: HAI-2

Histology type: endometrial carcinoma

Country: Japan

Region: Okayama

Followed up time :

Subgroup 1 name : weak epithelial staining

Subgroup 1 number: 21

Subgroup 2 name: moderate staining;high staining

Subgroup 2 number: 25;40

Conclusion: These findings indicate that HAI-2 could be considered used as favorable prognosis markers for endometrial cancer.

Sample type : tissue

Sample method: immunohistochemistry

Expression pattern : high expression (score 2)

Expression elevation: The level of HAI-2 staining in epithelial cells was classified into three groups by scoring the percentage of positive cells: strong (2); >50% of cells stained, moderate (1); 10–50% of cells stained, and weak (0); <10% of cells stained.Low epithelial expression, score 0–1; high epithelial expression, score 2

Statictics: cutoff<60;cutoff>60

Cohort age: 32;24
