of borderline significancep = 0.09
Interestingly, in a separate multivariate analysis of the endometrioid subgroup, the role of CK5/6 expression appeared to be of borderline significance (HR = 2.0; p = 0.09 ), while histologic grade (HR = 2.3; p = 0.03 ), vascular invasion (HR = 4.4; p = 0.001 ) and clinical stage (HR=6.1; p < 0.0001 ) obtained still an independent prognostic value.
