In terms of histologic subgroup (Figure 5), NUF2, CDCA3/4/5/8 were significantly overexpressed in serous endometroid adenocarcinoma (SEA) than endometroid endometrial adenocarcinoma (EEA) and mixed serous and endometrioid adenocarcinoma (MSE) (all p<0.05), except that overexpressed CDCA7 was significantly associated with EEA. This evidence concerns the gene NUF2 and endometrioid adenocarcinoma.
