Serum HE4 levels were measured by immunoassay before starting primary treatment. A mean serum HE4 level of 72.6 pmol\/L was used to divide the patients into low and high HE4 groups. Patient characteristics, clinicopathological variables, and survival outcomes were compared between the two groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The low and high HE4 groups included 55 (82.1%) and 12 (17.9%) patients at diagnosis, respectively. Higher HE4 levels were significantly associated with older age at diagnosis (age &lt;50: .0% vs age \u226550: 100.0%; P = .002), menopause (premenopause: 8.3% vs postmenopause: 91.7%; P = .009), higher FIGO stage (stage I\u2013II: 33.3% vs III\u2013IV: 66.7%; P = .017), large tumor size (&lt;4.0\u00a0cm: 41.7% vs \u22654.0\u00a0cm: 58.3%; P = .029), positive lymph node metastasis (negative: 41.7% vs positive: 58.3%; P = .049), and involvement of the parametrium (negative: 25.0% vs positive: 75.0%; P = .002). Higher HE4 level was a predictive factor for worse overall survival but not for progression-free survival. Elevated HE4 levels were not independent factors for the prediction of either overall survival or progression-free survival. Subgroup analysis by histological type revealed similar results for patients with squamous cell carcinoma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
