For tumor histological subtype grouping, the rates of weakly positive SHBG in group 1 (serous tumor), group 2 (mucinous and endometrioid tumors) and group 3 (clear cell, mixed and undifferentiated tumors) were 25.2% (41/163), 45.9% (17/37) and 14.8% (4/27) respectively, and strong SHBG detection rates in these three groups were 41.1% (67/163), 18.9% (7/37) and 40.7% (11/27), respectively. This evidence concerns the gene SHBG and endometrioid tumor.
