“…There is growing evidence that HE4 may be useful as a prognostic marker in EC, with many studies showing an association between serum HE4 and poor prognostic histopathological factors, including ≥50% MI [ 27 , 31 , 35 , 42 , 55 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 ], CI and stage [ 42 , 60 , 65 , 66 , 69 ], presence of LVSI [ 31 , 42 , 55 , 60 , 64 , 66 , 68 , 69 ], tumour size [ 31 , 55 , 67 , 68 , 69 , 70 ] and LNM [ 27 , 31 , 32 , 44 , 55 , 60 , 64 , 65 , 68 , 69 ]. Capriglione et al demonstrated that the proportion of EC patients with a cut-off of HE4 >70 pM was 42%, 77%, 90%, 93% and 100% at stages IA, IB, II, III and IV, respectively, and suggested ideal serum HE4 cut-offs by stage with >80% sensitivity and >95% specificity [ 71 ].…”
