When comparing ATAD2 expression with clinical and histopathological variables for aggressive endometrial cancer, we find a highly significant association between high ATAD2 expression and high FIGO (International Federation of Gynecology and Obstetrics) stage, non-endometrioid subtype, high grade and aneuploidy (Table 1; all P-values ≤0.001). The gene discussed is ATAD2; the disease is endometrial cancer.
