Clinical value of HE4,CA125 and ROMA in diagnosis of ovarian epithelial malignant tumor / 中国实用妇科与产科杂志

OBJECTIVE: To investigate the value of HE4,CA125 and ovarian malignant tumor risk prediction models(ROMA)in the diagnosis of ovarian epithelial malignant tumors.METHODS: The clinical and pathological data of 247 patients with ovarian tumors(EOC 139 cases,BOT 18 cases,and benign ovarian tumor 90 cases)and 39 patients with uterine fibroids in Liaoning Tumor Hospital from September 2016 to August 2017 were retrospectively analyzed. The levels of serum CA125 and HE4 were measured before operation. The ROMA values were calculated and the relationship between CA125,HE4,ROMA values and clinical pathological parameters were analyzed. The diagnostic evaluation index was calculated,the receiver operating characteristic(ROC)curve was drawn,and the AUC value was also calculated.RESULTS: The positive rate of HE4 in the ovarian epithelial malignant tumor group was significantly higher than that in other groups before and after menopause,the difference being statistically significant(P0.05).There was no significant statistical difference in the positive rate of ROMA before or after menopause(P>0.05).The sensitivity of CA125 was higher than that of HE4 and ROMA. Specificity of HE4 was higher than that of CA125 and ROMA.Correct diagnosis index of ROMA was higher than that of HE4 and CA125.CONCLUSION: For the diagnosis of ovarian malignant epithelial tumors,the combined detection of serum HE4 and CA125 and ROMA model is superior to the individual detection of HE4 and CA125.

PTEN expression and single nucleotide polymorphisms in epithelial tumors of the ovary / 부인종양

OBJECTIVE: Phosphate and tensin homolog deleted on chromosome 10 (PTEN) is a potent tumor suppressor gene, localized to chromosome 10q23, and shows extensive homology with auxilin and tension. PTEN has variety roles involved in cell proliferation, invasion, and migration in tumorigenesis of solid tumors. In this study, the expression of the PTEN in the ovarian epithelial tumors, including benign, borderline malignancy, and adenocarcinomas was investigated. METHODS: Immunohistochemical expression of PTEN were analyzed in formalin fixed tumor tissues of 20 benign cystadenomas, 22 borderline tumors, and 49 malignant ovarian cancer. In the same tissue extracts, single nucleotide polymorphism were studied. RESULTS: Most of benign and borderline ovarian tumors revealed strong positive reaction, but a few cases showed negative reaction or weak positive reaction. In adenocarcinomas, 33% of cases was negative, and 43% was focal weakly staining, grade 1. The remainder of adenocarcinomas showed strong nuclear staining. In SNP assay, A/A allele of rs1234213 shows low frequency, but A/G allele reveals high frequency. C/C allele of rs701848 shows high frequency, and rs9651492 is not detected polymorphism. CONCLUSION: These results suggest that loss of PTEN expression is associated with tumorrigenesis of ovarian epithelial tumors, and is related with single nucleotide polymorphism.

Expression of Proliferating Cell Nuclear Antigen and p53 Protein in Ovarian Epithelial Tumors

p53 gene mutation is commonly accepted to be associated with loss of negative cell cycle control and progression of tumors. The proliferative activity of tumor cells is considered to be a valuable indicator of tumor aggressiveness. This study is intended to compare p53 protein expression with cell proliferation rates in the ovarian epithelial tumors according to the various clinicopathological parameters. Immunohistochemistry using monoclonal p53 antibody (DO-1) and PCNA antibody (PC10) was applied to 56 cases of ovarian epithelial tumors including 17 cases of borderline tumor. The results were as follows. Both immunohistochemical staining of PCNA and p53 protein showed positive reactions confined to the nuclei of tumor cells. There were significant differences of p53 protein expression rates between borderline malignancies (11.8%) and cystadenocarcinomas (56.4%) of ovary. The expression rate of p53 protein was not significantly different according to the differentiation and the stage, but the cases of strong positive reaction to p53 protein were more frequently noted in the poorly differentiated and advanced staged tumors. The PCNA indices of p53 strong positive cases were higher than those of p53 weak positive cases. In summary, p53 protein and PCNA expression may be used as an adjuvant in differentiating borderline lesions from carcinomas of ovary and predicting their biological behaviors.

Correlation of Histologic Findings of Ovarian Epithelial Tumors with Expression of Proliferating Cell Nuclear Antigen and Flow Cytometric DNA Analysis

The prognosis of malignant ovarian tumor is poorer than that of borderline malignant ovarian tumor, Therefore an accurate diagnosis and estimation of the biologic behavior of the tumor are necessary for proper management of the patient. The histologic investigation of the tumor may provide information on the estimation of the malignant potential of tumor cells, but it may be a questionable method because of the subjective determination of tumor grade. Quantification of proliferative activity of tumor cells may play a role as an objective method to provide an estimation of the malignant potential of tumor cells. An evaluation of histologic findings was done on 84 cases of ovarian mucinous and serous tumors that were surgically resected and diagnosed during the period from January 1981 through July 1992. The proliferating cell nuclear antigen (PCN A) labelling index estimated from the immunohistochemical stain for PCN A and the Sphase fraction and porliferative index obtained from flow cytometric DN A analysis were assessed each other with histologic findings. The results are as follows: The presence of aneuploidy in malignant tumors was statistically significant as compared with benign tumors. The borderline malignant tumors showed no significant difference between the number of diploidy and aneuploidy. The PCNA labelling index, S-phase fraction and proliferative index tended to increase as the histologic grade of tumors went up. They were higher in malignant tumors than in others. The PCN A labelling index, S-phase fraction and proliferative index were higher in tumors with aneuploidy than in those with diploidy. In contrast to borderline malignant tumors, the PCNA labelling index in malignant tumors revealed a significant relation with the mitotic index. The S-phase fraction and proliferative index showed, in malignant tumors, a close correlation with the architectural grade and nucleolar grade, but not in borderline malignant tumors. Considering these results, the presence of aneuploidy, PCNA label.
