ABSTRACT
Objective:To investigate the clinical values of progastrin-releasing peptide (Pro-GRP), neuron-specific enolase (NSE), cytokeratin 19 fragment antigen 21-1 (CYFRA21-1), squamous cell carcinoma antigen (SCCA) and human human epididymis protein 4 (HE4) detections in the diagnosis of lung cancer patients.Methods:The clinical data of 200 lung cancer patients who were admitted to the Second Affiliated Hospital of Xuzhou Medical University from January 2020 to December 2021 were retrospectively analyzed. According to the pathological type, the patients were divided into lung adenocarcinoma group (80 cases), lung squamous cell carcinoma group (75 cases) and small cell lung cancer group (45 cases). Fifty patients with benign lung diseases and 50 healthy physical examiners who were admitted to the hospital during the same period were selected. All the subjects were tested for the levels of Pro-GRP, NSE, CYFRA21-1, SCCA and HE4, and the differences of each index level in the subjects of different subgroups were compared. The receiver operating characteristic (ROC) curve was drawn, and using pathological diagnosis result as the gold standard, the diagnostic efficacy of each index alone and in combination for lung cancer was compared.Results:The serum levels of Pro-GRP, NSE, CYFRA21-1, SCCA and HE4 in lung cancer group were higher than those in the benign lung diseases group and the healthy control group (all P < 0.001). There were no statistical differences in the levels of serum Pro-GRP, NSE, CYFRA21-1, SCCA and HE4 between the benign lung diseases group and the healthy control group (all P > 0.05). The levels of Pro-GRP, NSE and HE4 in the small cell lung cancer group were higher than those in the lung adenocarcinoma group and the lung squamous cell carcinoma group (all P < 0.05). NSE and HE4 levels in the lung adenocarcinoma group were higher than those in the lung squamous carcinoma group (both P < 0.05), while CYFRA21-1 and SCCA levels were lower than those in the lung squamous carcinoma group (both P < 0.05). The AUC of lung cancer diagnosed by HE4 was the largest (0.813), the AUC of lung adenocarcinoma diagnosed by HE4 was the largest (0.824), the AUC of lung squamous carcinoma diagnosed by CYFRA21-1 was the largest (0.884), and the AUC of small cell lung cancer diagnosed by NSE was the largest (0.959). The AUC of lung cancer diagnosed by combined detection of 5 indicators was 0.951, the AUC of lung adenocarcinoma and small cell lung cancer diagnosed by combined detection of 5 indicators was 0.975 and 0.996, and the AUC of lung squamous cell carcinoma diagnosed by combined detection of CYFRA21-1, SCCA and HE4 was 0.967. Conclusions:The levels of Pro-GRP, NSE, CYFRA21-1, SCCA, HE4 and other indicators have certain clinical values in the diagnosis of lung cancer and its pathological types, and the combined detection of each index is more valuable than a single index.
ABSTRACT
Objective:To investigate the diagnostic values of human epididymis protein 4 (HE4), endothelial cell specific molecule-1 (ESM-1) and epidermal growth factor receptor (EGFR) for lung cancer.Methods:The clinical data of 90 patients with lung cancer and 50 patients with benign lung diseases diagnosed by the pathological examination in Tangshan People's Hospital from December 2019 to January 2021 were retrospectively analyzed, and 40 healthy physical examiners in the same period were selected as the controls. The serum HE4 levels were detected by electrochemiluminescence method. The serum ESM-1 and EGFR levels were tested by enzyme-linked immunosorbent assay. The differences in serum HE4, ESM-1 and EGFR levels between the three groups were compared; logistic regression analysis was used to screen out the effective indicators for the diagnosis of lung cancer and to construct a prediction model for the diagnosis of lung cancer. Using pathological diagnosis result as the gold standard, the receiver operating characteristic (ROC) curve was drawn, and the diagnostic efficacy of indicators for lung cancer was evaluated.Results:The levels of serum HE4 in lung cancer group, benign lung diseases group and healthy control group were 119.55 pmol/L (82.06 pmol/L, 189.00 pmol/L), 58.84 pmol/L (45.62 pmol/L, 69.41 pmol/L) and 42.67 pmol/L (37.09 pmol/L, 51.84 pmol/L), the levels of ESM-1 were 33.00 ng/ml (25.85 ng/ml, 47.40 ng/ml), 20.14 ng/ml (11.93 ng/ml, 28.90 ng/ml) and 15.39 ng/ml (11.84 ng/ml, 20.19 ng/ml), and the levels of EGFR were 46.60 pg/ml (37.45 pg/ml, 58.98 pg/ml), 32.77 pg/ml (26.27 pg/ml, 40.86 pg/ml) and 30.43 pg/ml (27.54 pg/ml, 35.75 pg/ml), and the differences in each indicator among the three groups were statistically significant (all P < 0.001). The levels of serum HE4, ESM-1 and EGFR in lung cancer group were higher than those in benign lung diseases group and healthy control group. In patients with lung cancer, logistic regression analysis was performed with HE4 (X 1), ESM-1 (X 2) and EGFR (X 3) as the independent variables and pathological diagnosis as the dependent variable, and a lung cancer prediction regression model was established: P = 0.171X 1+0.351X 2+0.184X 3-24.660. The accuracy of this model in predicting lung cancer could reach 98.5%, and serum HE4, ESM-1 and EGFR were risk factors for the occurrence of lung cancer (all P < 0.05). The area under ROC curve from high to low was HE4 (0.960), ESM-1 (0.942) and EGFR (0.859). The diagnostic sensitivity of serum HE4 63.67 pmol/L for lung cancer was 86.7%, and the specificity was 97.5%. Both serum HE4 ( r = 0.304, P = 0.004) and ESM-1 ( r = 0.416, P < 0.001) were correlated with EGFR. Conclusions:Serum HE4, ESM-1 and EGFR can be used as effective indicators for the diagnosis of lung cancer, and the prediction model established based on the three serum tumor markers is of good value for the diagnosis and prediction of lung cancer.

ABSTRACT
Background: Ovarian malignancies has the highest mortality rate among all gynaecological malignancies. Surface epithelial tumors form two thirds of all ovarian neoplasm and 90% of all ovarian cancers are surface epithelial carcinomas. Mortality in case of ovarian malignancy is high due to late diagnosis. Early and accurate diagnosis can improve the case specific management. HE4 (Human Epididymis Protein 4) which is proved to be overexpressed in the ovarian cancer cells, is considered a new biomarker for ovarian cancer diagnosis which helps in early diagnosis and patient management. Aims and objectives of the study was to evaluate the immunohistochemical expression of HE4 in various ovarian malignancies.Methods: It was a cross sectional, prospective, single institution-based study, conducted in the department of Pathology in collaboration with the Department of Gynaecology and Obstetrics, from December 2016 to January 2019 in institution. A total 74 ovarian malignancies were selected for this study.Results: Serous carcinoma was the most common ovarian malignancy followed by endometrioid carcinoma. Highest percentage of expression of HE4 was seen in high grade serous cancer and malignant endometrioid tumor.Conclusions: HE4 was highly expressed in malignant ovarian tumour especially serous and endometrioid carcinoma and can be used as an important biomarker for malignant ovarian neoplasm. Expression in high grade ovarian serous cancer support its prognostic value also.
ABSTRACT
Objective: To investigate the value of risk ovarian malignancy algorithm (ROMA) in evaluation of the risk of epithelial ovarian cancer and its association with the clinical pathological stages, and to provide a basis for the clinical diagnosis and treatment and prognosis analysis of epithelial ovarian cancer.Methods: The clinical materials of 135 patients with ovarian tumor confirmed by paraffin section pathology after operation were retrospectively analyzed. The patients were divided into benign ovarian tumor group(n=66), epithelial ovarian cancer group(n=58) and non-epithelial ovarian cancer group(n=11).According to the cutoff values of HE4,CA125,and ROMA of the patients in various groups,the positive rates of HE4,CA125,and ROMA of the patients in various groups were calculated.Based on the serum levels of human epididymis protein 4(HE4) and carbohydrate antigen 125(CA125) detected before operation of the patients in various groups, the relationships between the positive rates of serum HE4, CA125 and ROMA and the clinical stages of the patients with ovarian cancer;their diagnosis efficacies in the patients with ovarian cancer were evaluated. Results: The serum CA125, HE4 levels and ROMA value of the patients in epithelial ovarian cancer group were significantly higher than those in benign ovarian tumor group and non-epithelial ovarian cancer group (P0.05). Among the three indexes, ROMA had the highest diagnostic efficacy index and CA125 had the lowest.Conclusion: The diagnostic value of ROMA for evaluating the risk of epithelial ovarian cancer was higher than those of CA125 and HE4, which has a better diagnostic value for the postmenopausal patients and can improve the early diagnosis efficiency of ovarian cancer.
ABSTRACT
Objective@#To explore the diagnostic value of combined detection of serum human epididymis protein 4 (HE4) and carbohydrate antigen 125 (CA125) for ovarian epithelial cancer.@*Methods@#Patients who underwent surgery for the adnexal tumor at Shanxi Provincial Cancer Hospital from January 2012 to December 2017 were enrolled. According to the postoperative pathological results, these patients were divided into the ovarian epithelial cancer group (494 cases) and benign ovarian disease group (462 cases). The serum expressions of HE4 and CA125 in the two groups were detected by enzyme-linked immunosorbent assay (ELISA) and chemiluminescence immunoassay. The diagnostic value of detection of HE4 and CA125 alone or in combination for ovarian epithelial cancer was analyzed.@*Results@#The median levels (P 25 - P 75) of serum CA125 and HE4 in ovarian epithelial cancer group were 273.34 U/ml (39.34 U/ml, 709.74 U/ml) and 199.08 pmol/L (75.81 pmol/L, 449.20 pmol/L), which were higher than those in ovarian benign disease group [16.30 U/ml (6.30 U/ml, 53.60 U/ml) and 39.54 pmol/L (29.57 pmol/L, 53.80 pmol/L)] (both P < 0.05). There was a positive correlation between serum CA125 and HE4 levels in ovarian epithelial cancer group (r = 0.481, P < 0.01). Serum CA125 and HE4 levels in patients with stage Ⅲ and Ⅳ were higher than those in patients with stage Ⅰ and Ⅱ (both P < 0.05), and serum CA125 and HE4 levels in patients with poor differentiation were higher than those in patients with moderate differentiation (P < 0.05). Compared with CA125, the specificity and positive predictive value of serum HE4 for the diagnosis of ovarian epithelial cancer were higher (both P < 0.01). Compared with HE4 alone, the sensitivity of CA125 combined with HE4 increased (P = 0.004) and the specificity decreased (P = 0.044). When both CA125 and HE4 were positive for positive results, compared with HE4 alone, the specificity and positive predictive value increased (both P < 0.01), but the sensitivity decreased (both P < 0.01). In patients with CA125+ HE4-, the sensitivity and specificity decreased, while in CA125- HE4+ patients, the specificity was elevated, but the difference was not statistically significant (P = 0.892). When one of CA125 and HE4 was positive for positive results, the sensitivity and negative predictive value increased (both P < 0.01), but the specificity and positive predictive value decreased (both P < 0.01). The area under the curve of serum CA125 and HE4 combined detection was 0.911, indicating its clinical diagnostic value was better than that of the two alone.@*Conclusions@#In the diagnosis of epithelial ovarian cancer, the specificity of serum HE4 is higher than that of CA125, but the sensitivity is lower than that of CA125. The combined detection of HE4 and CA125 is more conducive to improve the diagnostic accuracy of ovarian epithelial cancer.

ABSTRACT
OBJECTIVE@#To compare the performance of serum cancer antigen 125 (CA125), human epididymis protein 4 (HE4), Risk of Ovarian Malignancy Algorithm (ROMA) and Copenhagen index (CPH-I) for differential diagnosis of benign and malignant diseases in patients with ovarian mass.@*METHODS@#We retrospectively analyzed the data of 719 women with pelvic mass, and the performance of preoperative serum levels of CA125 and HE4, ROMA and CPH-I for differential diagnosis of the masses was compared.@*RESULTS@#Of the 710 women analyzed, 531 were diagnosed with benign ovarian lesions, 44 with borderline ovarian tumors (BOTs), 119 with epithelial ovarian cancers (EOCs), and 25 with non-EOCs. In differentiating ovarian cancer (OC) and BOT from benign lesions, the area under the receiver-operator characteristic (ROC) curve (AUC) was 0.854 for HE4, 0.856 for ROMA, 0.854 for CPH-I, and 0.792 for CA125, demonstrating better diagnostic performance of HE4, ROMA, and CPH-I than CA125 alone; the diagnostic sensitivity was 56.9% for HE4, 70.2% for CA125, 69.1% for ROMA, and 63.8% for CPH-I; the specificity was the best with HE4 (94.4%) and CPH-I (94.7%). In sub-analysis of EOC benign lesions, the AUCs of HE4, ROMA, and CPH-I increased to 0.946, 0.947, and 0.943, respectively, all greater than that of CA125 (0.888). In other sub-analyses, HE4, ROMA, and CPH-I all showed greater AUCs than CA125 alone.@*CONCLUSIONS@#This study confirms the accuracy of HE4, ROMA, and CPH-I for differentiating malignant from benign ovarian mass, and all these 3 tests show better performance than CA125. Furthermore, HE4 and CPH-I is superior to ROMA and CA125 in terms of specificity, while CA125 and ROMA have better diagnostic sensitivities.

Epithelial ovarian cancer (EOC) has the highest mortality rate among the gynecological malignancies. Because of its early symptoms are not obvious and lack of effective screening methods, more than 70％ patients have been diagnosed at late stage (stage Ⅲ-Ⅳ). Although the 5-year progression-free survival (PFS) of EOC was prolonged with the improvement of treatment methods, its prognosis was still poor, and 50％-95％ patients relapsed within 2 years after treatment. Human epididymis protein 4 (HE4) and carbohydrate antigen 125 (CA125) are widely used in the evaluation of diagnosis, treatment efficacy and prognosis of EOC, but the evaluation effect of both HE4 and CA125 is rarely reported. Therefore, it is necessary to summarize the research progress of HE4 and CA125 in evaluating the diagnosis, treatment efficacy and prognosis of EOC.
ABSTRACT
Objective To investigate the expression of human epididymal protein 4 ( HE4) and its effect on prognosis in patients with epithelial ovarian cancer (EOC). Methods From 2009 to 2014,ninety-eight cases of epithelial ovarian cancer (EOC group) and 29 cases of benign ovarian tumor (benign group) and 100 healthy subjects (control group) were selected as research subjects. The serum HE4 was detected by double antibody sandwich enzyme-linked immunosorbent assay (ELISA),and the positive expression was determined by HE4＞150 pmol/L in serum. The concentration and positive rate of serum HE4 were compared among the three groups. The median serum HE4 level of EOC patients before treatment was divided into high level HE4 group and low level HE4 group. The median survival time of the two groups of EOC patients was compared. Results The median value of serum HE4 concentration (four percentile) in EOC group was 421. 8 (68. 7 ～ 2173. 9) pmol/L,47. 8 (35. 24 ～ 68. 5) pmol/L in the benign group and 43. 8 ( 32. 91 ～ 70. 4) pmol/ L in the control group. The serum concentration of HE4 in the EOC group was significantly higher than that in the benign group and the control group ( P＝0. 000) . The serum HE4 concentration in group EOC was significantly higher than that in benign group and control group (P＜0. 01),but there was no significant difference between benign group and control group (P＞0. 05). The positive rate of serum HE4 in the EOC group was 74. 5 (73/98),the positive rate of the benign group and the control group were 0,the difference between the three groups was statistically significant (P＝0. 000). The positive rate of serum HE4 in the EOC group was significantly higher than that in the benign group and the control group ( P＜0. 01), while the benign group and the control group had no statistical significance (P＞0. 05). The median survival time of EOC patients in low level HE4 group was 66. 2 months,while that in high level HE4 group was 36. 9. The difference between two groups was statistically significant (P＝0. 001). Conclusion The serum HE4 level of EOC patients was significantly higher than that of patients with benign ovarian tumors and healthy controls. The higher serum HE4 level,the worse the prognosis, and the shorter the survival time of patients. Therefore,the expression level of serum HE4 can be used for the diagnosis and prognosis of ovarian cancer.

ABSTRACT
Objective To observe the expression of human epididymis protein 4 (HE4) and carbohydrate antigen 125 (CA125) in endometrial carcinoma(EC) tissues,and to explore the relationship between the expression of HE4 and CA125 and the occurrence and development of EC.Methods The EC and paracancerous tissue specimens of 35 EC patients were selected from December 2015 to December 2016 in the First People's Hospital of Yibin City.The expression of HE4 and CA125 in EC tissues and paracancerous tissues was detected by immunohistochemistry.The relationship between the expression of HE4,CA125 and the clinicopathological features of EC was analyzed;and the correlation between HE4 and CA125 was analyzed too.Results The positive expression rates of HE4 and CA125 in EC tissues were 82.9％ (29/35) and 74.3％ (26/35);they were 11.4％ (4/35) and 14.3％ (5/35) in paracancerous tissues respectively;the positive expression rates of HE4and CA125 in EC tissues were significantly higher than those in paracancerous tissues(x2 =35.831,25.533;P ＜0.05).The positive expression rates of HE4 and CA125 in stage Ⅲ and Ⅳ EC tissues were 100.0％ (20/20) and 90.0％ (18/20);they were 60.0％ (9/15) and 53.3％ (8/15) in stage Ⅰ and Ⅱ EC tissues respectively;the positive expression rates of HE4 and CA125 in stage Ⅲ and Ⅳ EC tissues were significantly higher than those in stage Ⅰ and Ⅱ EC tissues(x2 =9.655,4.266;P ＜ 0.05).The positive expression rates of HE4 and CA125 in medium and low differentiated EC tissues were 100.0％ (18/18) and 83.3％ (15/18);they were 64.7％ (11/17) and 64.7％ (11/17) in highly differentiated EC tissues respectively;the positive expression rates of HE4 and CA125 in medium and low differentiated EC tissues were significantly higher than those in highly differentiated EC tissues(x2 =7.667,4.137;P ＜0.05).The positive expression rates of HE4 and CA125 in EC tissues with myometrial invasion depth≥ 1/2 were 100.0％ (18/18) and 94.4％ (17/18);they were 64.7％ (11/17) and 52.9％(9/17) in EC tissues with myometrial invasion depth ＜ 1/2 respectively;the positive expression rates of HE4 and CA125 in EC tissues with myometrial invasion depth ≥ 1/2 were significandy higher than those in EC tissues with myometrial invasion depth ＜ 1/2(x2 =7.667,7.884;P ＜ 0.05).The positive expression rates of HE4 and CA125 in EC tissues with lymph node metastasis were 100.0％ (19/19) and 78.9％ (15/19);they were 62.5％ (10/16) and 68.8％ (11/16) in EC tissues without lymph node metastasis respectively;the positive expression rate of HE4 in EC tissues with lymph node metastasis was significantly higher than that in EC tissues without lymph node metastasis (x2 =8.599,P ＜ 0.05),but there was no significant difference in the positive expression rate of CA125 in EC tissues with lymph node metastasis and without lymph node metastasis (x2 =0.473,P ＜0.05).The expression of HE4 and CA125 in EC tissues was not related to age,tumor size and pathological type(P ＜ 0.05).The expression of HE4 in EC tissues was positively correlated with the expression of CA125 (r =0.608,P ＜0.05).Conclusion HE4 and CA125 may be involved in the development and development of EC.The expression of HE4 and CA125 is high in EC tissues,the expression level of them is closely related to clinical stage,histological differentiation and myometrial invasion depth of EC.The high expression of HE4 was also related to lymph node metastasis.
ABSTRACT
Objective To investigate the clinical value of serum human epididymis protein 4 (HE4), carbohydrate antigen 125 (CA125) combined with risk of ovarian malignancy algorithm (ROMA) index in the diagnosis of ovarian cancer. Methods A total of 541 patients in the Department of Gynaecology in Baoji Central Hospital from August 2016 to February 2018 were collected. The serum HE4 and CA125 levels were measured by using electrochemiluminescence immunoassay in 226 cases of ovarian cancer (ovarian cancer group), 315 cases of ovarian benign disease (ovarian benign disease group) and 100 female healthy people (the control group). ROMA index was calculated according to ROMA model and the results were analyzed statistically. Results The levels of serum HE4, CA125 and ROMA index were significantly different in premenopausal and postmenopausal ovarian cancer group, ovarian benign disease group and the control group (all P<0.05). The sensitivity and Yonden's index of the three combined diagnosis of serum HE4, CA125 and ROMA for premenopausal ovarian cancer were 97.01 ％ and 77.01 ％ respectively, which were higher than those of a single detection (HE4:79.37％, 69.11％;CA125:76.06％, 66.38％;ROMA index:89.55％, 72.41％;χ2sensitivity=12.35, P=0.000;χ2Yonden's index=6.460, P=0.013. The sensitivity and Yonden's index ofthe three combined diagnosis of serum HE4, CA125 and ROMA for postmenopausal ovarian cancer were 98.99 ％ and 82.99 ％ respectively, which were higher than those of a single detection (HE4: 86.90 ％, 79.40 ％; CA125: 82.98 ％, 76.31 ％; ROMA index: 93.54 ％, 80.64 ％; χ2sensitivity = 14.25, P = 0.000;χ2Yonden's index= 4.822, P= 0.031). The area under the curve of the combined detection of three indicators was higher than that of a single detection (premenopausal group: 0.871 vs. 0.682, 0.626, 0.708; postmenopausal group: 0.981 vs. 0.724, 0.705, 0.833), and there were significant differences (premenopausal group: χ2 =11.24, P= 0.000; postmenopausal group: χ2= 16.38, P= 0.000). Conclusion The combined detection of serum HE4, CA125 and ROMA index can increase the sensitivity and accuracy for diagnosing ovarian cancer, which can provide a more reliable basis for diagnosis and screening of ovarian cancer.
ABSTRACT
Using Eu3+as a tracer,a sandwich?type assay was established. HE4 in serum specimens from 225 patients were detected by TRFIA. Serum levels of HE4 in pelvic tumors were quantitatively analyzed. From receiver operating characteristic (ROC) curves,the reference values was calculated for endometrial cancer,cervical cancer and ovarian cancer,respectively. Results The working range of serum HE4 for TRFIA was 10~10000 pmol/L with a sensitivity of 7.5 pmol/L. The method offered less interaction with CA125 and CA199,and also provided a better correlation with ECLA,while the CV of intra?assay was below 10%. HE4 levels were significantly higher in endometrial cancer,cervical cancer and ovarian cancer groups than in healthy volunteer group,while did not differ significantly between uterine fibroid group and healthy women group. As aging,the risk for developing pelvic tumors increased. The area of ROC for malignant tumors was all above 0.5 and the accurate interpretation of HE4 was 60 pmol/L. Conclusion A stable,precise HE4 TRFIA is well established,which is helpful in diagnosis of gynecologic cancers.
