HE4 and TPS3 protein in cancer tissue were measured by immunohistochemical method. Results:The difference in density of HE4 and TP53 protein was significant between LGSC and HGSC tissue,while serum CA12S did not show significant difference between different serum samples.There was significant difference in serum HE4 levels between LGSC and HGSC and the result was different within FIGO(Ⅰ+Ⅱ) stage,suggesting HE4 was not a reliable biomarker for the discrimination between LGSC and HCSC.HE4 had potential as a biomarker for the discrimination between LGSC and HGSC but the role in early diagnosis was limited.Conclusions:HE4 may be a reliable marker for differential diagnosis of LGSC and HGSC.But its role in early diagnosis of LGSC and HGSC need to be confirmed from the perspective of two-tier grade system.展开更多

Methods:Patients with ovarian cancer who underwent surgical resection in West Coast Medical Center of the Affiliated Hospital of Qingdao University between June 2013 and December 2016 were selected as the ovarian cancer group of the study, and healthy women who received physical examination in China University of Petroleum (East China) Hospital during the same period were selected as the control group of the study. Serum was collected from two groups of subjects to detect serum mesothelin and human epididymis secretory protein 4 contents, and the ovarian cancer lesions and adjacent lesions were collected from ovarian cancer group to detect the expression of proliferation, apoptosis and invasion genes. Results: Serum mesothelin and human epididymis secretory protein 4 contents of ovarian cancer group were significantly higher than those of control group;FUNDC1, LSD1, TNFAIP8, CXCR4, β-catenin, CD44, PELP1, Slug, ZEB1 and Snail mRNA expression in ovarian cancer lesions were significantly higher than those in adjacent lesions and positively correlated with serum mesothelin and human epididymis secretory protein 4 contents while MFN2, PTEN, FN14 and E-cadherin mRNA expression were significantly lower than those in adjacent lesions and negatively correlated with serum mesothelin and human epididymis secretory protein 4 contents. Conclusion: Serum mesothelin and human epididymis secretory protein 4 contents abnormally increase in patients with ovarian cancer and are associated with the infiltrative growth of cancer cells.展开更多

But its role in assessing the primary optimal debulking（OD） of EOC remains unknown. The purpose of this study is to elucidate the ability of preoperative HE4 in predicting the primary cytoreductive outcomes in advanced EOC, tubal or peritoneal carcinoma.Methods： We reviewed the records of 90 patients with advanced ovarian, tubal or peritoneal carcinoma who underwent primary cytoreduction at the Department of Obstetrics and Gynecology of Peking University People＇s Hospital between November 2005 and October 2010. Preoperative serum HE4 and CA125 levels were detected with EIA kit. A receiver operating characteristic（ROC） curve was used to determine the most useful HE4 cut-off value. Logistic regression analysis was performed to identify significant preoperative clinical characteristics to predict optimal primary cytoreduction.Results： OD was achieved in 47.7%（43/48） of patients. The median preoperative HE4 level for patients with OD vs. suboptimal debulking was 423 and 820 pmol/L, respectively（P〈0.001）. The areas under the ROC curve for HE4 and CA125 were 0.716 and 0.599, respectively（P=0.080）. The most useful HE4 cut-off value was 473 pmol/L. Suboptimal cytoreduction was obtained in 66.7%（38/57） of cases with HE4 ≥473 pmol/L compared with only 27.3%（9/33） of cases with HE4 〈473 pmol/L. At this threshold, the sensitivity, specificity, positive predictive value（PPV） and negative predictive value（NPV） for diagnosing suboptimal debulking were 81%, 56%, 67%, and 73%, respectively. Logistic regression analysis showed that the patients with HE4 ≥473 pmol/L were less likely to achieve OD（odds ratio =5.044, P=0.002）.Conclusions： Preoperative serum HE4 may be helpful to predict whether optimal cytoreductive surgery could be obtained or whether extended cytoreduction would be needed by an interdisciplinary team.展开更多
