Objective:To study the diagnostic value of multiple tumor markers in malignant ovarian neoplasm.Methods:Sera obtained from 430 patients with ovarian masses (110 cases were malignant ovarian tumors,320 cases were benign ovarian tumors) before operation,and from 50 healthy women as control.Serologic examination of tumor markers included CA125,TSGF,SA,CEA,AFP,HCG and Fer.Results:The serum levels of CA125,TSGF,SA and Fer in patients with ovarian cancer were higher than those in patients with benign ovarian tumors (P<0.05),also in control group (P<0.05).In the diagnostic value of application for malignant ovarian neoplasm,CA125,TSGF and SA were better than the others.The sensitivity,specificity and accuracy in diagnosis of ovarian cancer were 86.4%,82.8%and 83.7% respectively for CA125 alone,78.2%,81.3%and 80.5% for TSGF alone,74.5%,81.9%and 80.0% for SA alone,whereas 95.5%,45.6%and 58.4% for multiple tumor markers combined in which 1 or more indices showed positive,93.6%,80.6%and 84.0% for that in which 2 or more indices showed positive,and 87.3%,90.3%and 89.5% for that in which 3 or more indices show positive.Conclusion:multiple tumor markers examination could improve the diagnosis of ovarian cancer,and examination of CA125,TSGF and SA combined is most ideal.

Accuracy of Intraoperative Frozen Section in the Diagnosis of Ovarian Neoplasms

Objective: The aim of the work is to evaluate the accuracy of intraoperative frozen section in the diagnosis of ovarian neoplasms in Zagazig University. Design: A prospective cross sectional cohort study. Method: This study was performed between March 2011 and March 2012, on 50 patients presented with ovarian mass. Gross examination of the tumor removed was done by inspection and palpation. The specimen was then cut with a sharp knife into two halves. The most appropriate area thought to be representative of lesion was chosen. The number of sections frozen was depended on the type and size of the tumor. Seven to eight μm sections were obtained and stained with hematoxylin-eosin. The specimens were then fixed in formalin. Paraffin blocks of the sections were processed in the routine way and sections were stained with hematoxylin and eosin (H and E). The diagnosis obtained by intraoperative frozen section based on cellularity and cell morphology was compared with final histopathological diagnosis in terms of diagnostic sensitivity, to differentiate between benign and malignant lesions. Assessment of the overall accuracy of the intraoperative diagnosis was classified as concordant or discordant. Results: There was no statisticaly significant differencre in the studied patients as regard the clinical data, macroscopic and intraoperative picture, while there was statisticaly significat association as regard the laterality of the ovarian masses. The validity of frozen section in the diagnosis of benign tumour was 100% with 100% accuracy, specificity, positive predictive value, negative predictive value, while sensitivity & negative prediction for borderline tumour and specificity & positive prediction of malignant tumour were 100%, specifecity for borderline tumours was 95% while the positive predictive value was 33.3% with 96% accuracy for both malignant and borderline tumours. Conclusion: Intraoperative frozen section is accurate for rapid diagnosis of ovarian tumors. It can help surgeons avoid under-treatment or overtreatment of patients. Our study was designed prospectively using a small number of patients. The door is open to larger studies using a larger number of patients to be performed in order to substantiate our results.

Expression and significance of tumor suppressor gene p16 in human ovarian neoplasm

To observe the relationship between tumor suppressor gene p16 expression and ovarian cancer occurrence and development. Metbods: Using ABC immunohistochemistry method, we investigated the expression of p16 in 72 cases of ovarian neoplasm. Results: The positive rates of p16 in malignant, benign, borderline tumors and normal ovarian tissue were 7. 89%, 60.00%, 66. 67% and 83. 33%, respectively (P<0.01). In the cases whose tumors were more malignant and poorly differentiated, and who relapsed and died, the positive stainings were not discovered. Conclusiou: p16 is well related with the occurrence and development of malignant ovarian tumor.

Human ovarian neoplasm cell CD147 stimulates production and activation of matrix metalloproteinases in co-cultures with mouse fibroblasts

Objective: To investigate the expression of CD147 on human ovarian neoplasm cell lines and its influence on production and activation of matrix metallproteinases(MMPs). Methods: The expression of CD147 on different human ovarian neoplasm cell lines was studied by western blotting. Co-culture was carried out to investigate the stimulative effect of the positive expression CD147 cell HO-8910 on the production of MMPs of fibroblast cell in vitro. Zymography and immune blotting were used to study the production and activity of positive MMPs, at the time, to explore the relation between CD147 and MMPs. Results: CD147 was positively presented in 2 ovarian neoplasm cell lines(HO-8910,3-AO), but in SKOV3, TC-1,NIN3T3 cell was negative. MMP-2 and MMP-9 were detected by HO-8910 cell line, mouse fibroblast cell and co-culture cells; but the expression in co-culture cell is obviously higher than individual cultures of each type alone.CD147 stimulated MMPs in dose-dependent manner. Conclusion: CD147 causes increased production and activation of MMP-2, MMP-9.CD147 is probably a indirect marker of some ovarian cancer cells with invasion and metastasis.

TGF-β-regulated different iron metabolism processes in the development and cisplatin resistance of ovarian cancer

The impact of different iron metabolism processes(DIMP)on ovarian cancer remains unclear.In this study,we employed various gene chips and databases to investigate the role of DIMP in the initiation and development of ovarian cancer.cBioPortal was used to determine mutations in DIMP-associated genes in ovarian cancer.Kaplan-Meier plotter was used to examine the influence of DIMP on the prognosis of ovarian cancer.By analyzing 1669 serous ovarian cancer cases,we identified a range of mutations in iron metabolism genes,notably in those coding for the transferrin receptor(19%),melanotransferrin(19%),and ceruloplasmin(10%)in the iron import process,and glucose-6-phosphate isomerase(9%),hepcidin antimicrobial peptide(9%),metal regulatory transcription factor 1(8%),and bone morphogenetic protein 6(8%)in the iron regulation process.Compared to the unaltered group,the group with gene alterations exhibited a higher tumor mutation burden count(43 vs.54)and more advanced histologic grade(78.19%vs.87.90%).Compared to the normal ovarian counterparts,a reduction in expression was observed in 9 out of the 14 genes involved in iron utilization and 4 out of the 5 genes involved in iron export in ovarian cancer;in contrast,an increase in expression was observed in 2 out of the 3 genes involved in iron storage in ovarian cancer.Furthermore,in cisplatin-resistant cells compared to cisplatin-sensitive ones,the expression of all genes in iron storage and 13 out of 14 genes in iron import was decreased,while that of 8 out of the 10 genes in iron utilization was increased.In addition,survival curve analysis indicated that a higher expression in the majority of genes in the iron import process(12/21),or a reduced expression in most genes in the iron export process(4/5)correlated with poor progression-free survival.Additionally,TGF-βcould regulate the expression of most iron metabolism-associated genes;particularly,expression of genes involved in the iron storage process(2/2)was inhibited after TGF-β1 or TGF-β2 treatment.In conclusion,DIMP plays multifaceted roles in the initiation,chemo-resistance,and prognosis of ovarian cancer.Therapeutically targeting DIMP may pave the way for more tailored treatment approaches for ovarian cancer.

Immune pathway through endometriosis to ovarian cancer

Endometriosis is an estrogen-dependent inflammatory disease,defined by the presence of functional endometrial tissue outside of the uterine cavity.This disease is one of the main gynecological diseases,affecting around 10%-15%women and girls of reproductive age,being a common gynecologic disorder.Although endometriosis is a benign disease,it shares several characteristics with invasive cancer.Studies support that it has been linked with an increased chance of developing endometrial ovarian cancer,representing an earlier stage of neoplastic processes.This is particularly true for women with clear cell carcinoma,low-grade serous carcinoma and endometrioid.However,the carcinogenic pathways between both pathologies remain poorly understood.Current studies suggest a connection between endometriosis and endometriosis-associated ovarian cancers(EAOCs)via pathways associated with oxidative stress,inflammation,and hyperestrogenism.This article aims to review current data on the molecular events linked to the development of EAOCs from endometriosis,specifically focusing on the complex relationship between the immune response to endometriosis and cancer,including the molecular mechanisms and their ramifications.Examining recent developments in immunotherapy and their potential to boost the effectiveness of future treatments.

EZH2 Contributes to Anoikis Resistance and Promotes Epithelial Ovarian Cancer Peritoneal Metastasis by Regulating m6A

Objective:Histone modification has a significant effect on gene expression.Enhancer of zeste homolog 2(EZH2)contributes to the epigenetic silencing of target chromatin through its roles as a histone-lysine N-methyltransferase enzyme.The development of anoikis resistance in tumor cells is considered to be a critical step in the metastatic process of primary malignant tumors.The purpose of this study was to investigate the effect and mechanism of anoikis resistance in ovarian adenocarcinoma peritoneal metastasis.Methods:In addition to examining EZH2 protein expression in ovarian cancer omental metastatic tissues,we established a model of ovarian cancer cell anoikis and a xenograft tumor model in nude mice.Anoikis resistance and ovarian cancer progression were tested after EZH2 and N6-methyladenosine(m6A)levels were modified.Results:EZH2 expression was significantly higher in ovarian cancer omental metastatic tissues than in normal ovarian tissues.Reducing the level of EZH2 decreased the level of m6A and ovarian cancer cell anoikis resistance in vitro and inhibited ovarian cancer progression in vivo.M6a regulation altered the effect of EZH2 on anoikis resistance.Conclusion:Our results indicate that EZH2 contributes to anoikis resistance and promotes ovarian adenocarcinoma abdominal metastasis by m6A modification.Our findings imply the potential of the clinical application of m6A and EZH2 for patients with ovarian cancer.

Primary ovarian choriocarcinoma occurring in a postmenopausal woman:A case report

BACKGROUND Nongestational ovarian choriocarcinoma(NGOC)is a rare but aggressive neoplasm with limited sensitivity to chemotherapy and a very poor prognosis.Few cases of NGOC have been reported,and there is limited information regarding its clinical features,treatment protocols,or prognosis.CASE SUMMARY A postmenopausal woman in her 5th decade of life visited our clinic because of abnormal vaginal bleeding and an abdominal mass.Although she had been menopausal for more than eight years and her last abortion occurred nine years ago,she had an increased level of serumβ-human chorionic gonadotropin(β-hCG).Thus,an ovarian neoplasm of trophoblastic origin was suspected,and exploratory laparotomy was performed.Based on the patient’s clinical history and the histopathological examination and immunohistochemistry results obtained postoperatively,we concluded that she most likely had primary NGOC.Cytoreductive surgery was performed in combination with adjuvant chemotherapy comprising bleomycin,etoposide,and cisplatin.Serumβ-hCG levels decreased to normal after two cycles,and there was no evidence of recurrence after four cycles of chemotherapy.CONCLUSION Even in postmenopausal women,ovarian choriocarcinoma should be considered in the initial differential diagnosis for an adnexal mass.

EXPRESSION AND SIGNIFICANCE OF BASIC FIBROBLAST GWOWTH FACTOR AND FIBROBLAST GROWTH FACTOR RECEPTOR-1 IN OVARIAN EPITHELIAL NEOPLASM

Objective To study the relevance of expression of basic fibroblast growth factor (bFGF), fibroblast growth factor receptor 1 (FGFR 1) and carcinogenesis and progression of ovarian epithelial neoplasm. Methods Ten cases of normal ovarian tissues and 75 cases of ovarian epithelial neoplasm tissues were detected by immunohistochemical methods: S P for bFGF, FGFR 1,double immunohistochemistry Lab SA for Ki 67 antigen and bFGF. Results The expression level of bFGF, FGFR 1in ovarian epithelium and ovarian epithelial neoplasm showed a step wise increase in the following order:normal <benign <borderline <malignant; The expression level and intensity of bFGF and FGFR 1 were increased with the decrease of differentiation degree and increase of clinical stage in ovarian carcinoma; There was no statistical difference between the expression of bFGF, FGFR 1 in serous cystadenocarcinoma and that of mucinous cystadenocarcinoma; The expression of bFGF was correlated with that of FGFR 1 in neoplastic tissues; There were positive expression rates of bFGF and Ki 67 antigen in ovarian epithelial neoplasm. Conclusion As an important proliferative factor, bFGF plays an important role in carcinogenisis and progression of ovarian epithelial neoplasm.

A Case of Low-Grade Appendiceal Mucinous Neoplasm of Its Difficultly to Distinguish from a Right Ovarian Tumor Due to Postmenopause

We here present a rare case of appendiceal tumor mimicking ovarian tumor in menopause woman. The patient was a 56-year-old woman, G1P1, who presented to our hospital with a right adnexal cyst diagnosed at another hospital. Transvaginal echocardiography showed a cyst in the right adnexal region, and pelvic contrast-enhanced MRI revealed a small cyst in the same region. The left ovary was atrophic and identifiable. It was unclear whether the cyst was contiguous with the gastrointestinal tract. Blood tests showed no elevation of tumor markers. We considered its possibility of a gastrointestinal origin, but since right normal ovary was not found, we thought the tumor was of ovarian origin and decided on a laparoscopic resection of the right adnexa. Intraoperatively, we observed atrophied bilateral normal ovaries, and the pelvic tumor was contiguous to the appendix. Surgeons performed a laparoscopic appendectomy after consultation with us. After resection we searched the abdominal and pelvic cavities, but found no obvious disseminated lesions. The histological diagnosis was low-grade appendiceal mucinous neoplasm (LAMN), a rare benign tumor of the appendix. Appendiceal tumors can be difficult to differentiate from right ovarian tumors due to their close anatomic location in the pelvis. It is possible to determine whether the tumor is of ovarian or appendiceal origin by identifying normal ovaries and the location of the feeding vessels into the tumors. In our case, there were no lesions other than the appendix, but LAMN can metastasize to the ovary, cause pseudomyoxoma peritonei, or be an overlapping tumor with an ovarian tumor. If an appendiceal tumor is diagnosed after surgery for ovarian tumor, the intra-abdominal cavity should be searched for metastasis or dissemination, and a thorough search for ovarian lesions should be performed with the possibility of an overlapping tumor in mind.

PARP抑制剂与免疫检查点抑制剂联合治疗在妇科恶性肿瘤中的应用

近年来肿瘤靶向和免疫治疗的研究进展迅速,如多腺苷二磷酸核糖聚合酶抑制剂[poly(ADP-ribose)polymerase inhibitor,PARPi]、免疫检查点抑制剂(immune checkpoint inhibitors,ICI)等已改变了妇科肿瘤的传统治疗模式,但部分患者疗效有限或出现耐药。临床前研究发现,PARPi损伤DNA修复过程,可造成肿瘤突变负荷与肿瘤特异性抗原增加,调节肿瘤微环境,刺激肿瘤浸润淋巴细胞(tumor infiltrating lymphocytes,TIL)产生并促进抗肿瘤免疫反应,为PARPi与ICI联合治疗提供了理论基础。近年多项临床研究发现PARPi与ICI联合使用可显著改善妇科恶性肿瘤患者的预后。

N6-甲基腺苷(m6A)修饰是一种常见的表观遗传学修饰,动态调控RNA代谢的整个过程。m6A包括甲基转移酶、去甲基酶及m6A结合蛋白。m6A的甲基化修饰通过调节RNA的衰变、运输、剪切、翻译来调节细胞的增殖和分化,m6A与妇科恶性肿瘤的发生发展有关。笔者就近年来m6A甲基化修饰在宫颈癌、子宫内膜癌和卵巢癌中的相关研究进展进行回顾,分析m6A通过作用于RNA的修饰调节妇科恶性肿瘤发生发展的机制,为妇科恶性肿瘤的治疗、改善预后提供新的方向。

晚期上皮性卵巢癌误诊为盆腔结核一例

盆腔结核是由结核分枝杆菌引起的女性盆腔炎症,是慢性盆腔炎和不孕症的常见原因。由于盆腔结核可引起腹盆腔钝性疼痛、腹胀等特征与晚期上皮性卵巢癌相似,加之肺外结核没有特异的临床特征或影像学表现可以明确诊断,因此盆腔腹膜结核很容易与腹膜癌和晚期上皮性卵巢癌混淆。分析1例晚期上皮性卵巢癌患者,因卵巢占位组织穿刺病理及腹水脱落细胞学检查均未查见肿瘤细胞,遂行结核鉴别检查,患者结核菌素试验和结核分枝杆菌γ干扰素均为阳性,诊断为盆腔结核,后经病理证实为上皮性卵巢癌。对本病例的诊治过程进行总结,以期为临床处理晚期上皮性卵巢癌与盆腔结核诊断困难的病例积累一定经验。

机会性输卵管切除术对卵巢储备的短期影响:基于GRADE证据分级系统的随机对照试验荟萃分析

背景机会性输卵管切除术(OS)可以作为卵巢癌(OC)的一级预防手段,但由于卵巢与输卵管拥有同源血供系统,OS可能会引起卵巢功能的损害,从而增加卵巢老化和更年期提前的风险。目的基于GRADE证据分级系统,评价OS对卵巢储备的短期影响。方法于2022年9月,检索中国知网、万方数据知识服务平台、维普网、PubMed、Web of Science、Scopus,获取评估OS对卵巢储备短期影响的文献,检索时限均为建库至2022-09-10。由2名研究者独立筛选文献并提取数据,使用Jadad量表评价文献质量,Stata 17.0软件用于数据处理与荟萃分析,GRADEpro 3.2软件用于评估荟萃分析结果的证据质量。结果共纳入9项随机对照试验(RCT),包含482例患者,其中OS组238例、non-OS组244例。Jadad风险评估量表结果显示所纳入的RCT均为高质量文献。荟萃分析结果表明:相对于non-OS组,OS组抗苗勒氏激素(AMH)(WMD=-0.07,95%CI=-0.28~0.13,P=0.13)、卵泡刺激素(FSH)(WMD=-0.03,95%CI=-1.65~1.59,P=0.24)、黄体生成素(LH)(WMD=-0.39,95%CI=-1.62~0.83,P=0.08)、雌二醇(E2)(WMD=3.08,95%CI=-4.26~10.43,P=0.35)手术前后的变化差异无统计学意义(P>0.05)。GRADEpro软件对荟萃分析的结果显示,AMH的研究为高质量证据,FSH的研究为中等质量证据,E2和LH的研究为低质量证据。结论在短期内因良性疾病接受OS的未绝经女性的卵巢储备功能指标与未接受OS的女性无明显差异。已完成生育的绝经前女性通过OS来预防OC是合理的,但是这个结论仍有待于更长随访时间、设计更严谨且样本量更大的RCT来验证。
