These data are consistent with those of Salvesen et al,22 Stefansson et al,14 Geisler et al,18 and Liu et al,15 who described Ki-67 as a prognostic biomarker in endometrial cancer, although significance was generally lost after adjusting for important pathological variables like grade of disease and histological subtype. The gene discussed is MKI67; the disease is endometrial cancer.
