The differential genes were then, analyzed in the TCGA ovarian cancer data set for risk regression analysis and verified in the GSE26712 data set. In addition, we performed a functional enrichment analysis on the genes in the signature of hypoxia, and further analyzed the level of hypoxia risk and immune infiltration. Finally, a nomogram combining the hypoxia risk score, clinical stage, pathological grade, 3-year and 5-year survival rate was constructed. Results : A signature containing 12 hypoxia-related genes was identified as a Cox regression model for predicting the prognosis of ovarian cancer, and verified it in an independent data set. Subsequent enrichment analysis revealed that the signature is related to the immune system. We have also demonstrated a significant relationship between the signature of hypoxia and the infiltration of certain immune cells. Finally, the nomogram shows the accuracy of hypoxia characteristics in predicting ovarian cancer prognosis. Conclusion : We have established a good prognostic risk assessment model for ovarian cancer related to hypoxia risk, which provides personalized survival predictions and possible targeted treatment strategies.","PeriodicalId":11903,"journal":{"name":"European journal of gynaecological oncology","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47862508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods : In total 506 consecutive women referred because of abnormal cervical cytology or a positive high-risk HPV test, had an examination using OESD, LBC, and hrHPV testing. They were screened in 4 colposcopy clinics in New South Wales, Australia. In a retrospective audit, results were compared to the gold standard of colposcopy and biopsies if required. Sensitivity, specificity, area under the receiver operating characteristic (ROC)-curves, and differences using McNemar tests were calculated. All results were available for comparison on 474 patients. Results : The sensitivity to detect CIN II+ lesions by OESD, LBC and hrHPV-testing was 0.72, 0.81, and 0.88, and the specificity was 0.71, 0.95, and 0.76 respectively. The age- and previous-treatment adjusted area under the ROC curve for OESD was 0.83, for LBC 0.94, and for hrHPV testing 0.89. McNemar’s tests showed no significant difference in sensitivity between OESD and LBC ( p = 0.26), and no significant difference in specificity between OESD and hrHPV-testing ( p = 1.0) amongst patients without previous treatment. Conclusions : The optoelectronic screening device demonstrated comparable sensitivity to high quality cytology conducted in a hospital clinical setting. Specificity was comparable to hrHPV-testing in an approximate primary screening setting. OESD has the advantage of producing an immediate result and being easy to use without need of laboratory equipment. This device can potentially become an important tool in the prevention of cervical cancer, particularly in developing countries and resource-limited settings.","PeriodicalId":11903,"journal":{"name":"European journal of gynaecological oncology","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47553212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite advances in detection and treatment strategies over the past few decades, the current biomarkers of BC are less than satisfactory for effective prognosis and individualized treatment. This study aimed to investigate the new biomarkers to meet this urgent demand. Methods : The current study investigated the transcriptional levels of minichromosome maintenance genes (MCMs) in BC patients from the Oncomine, UALCAN database, and Gene Expression Profiling Interactive Analysis (GEPIA); protein expression levels of MCM proteins in BC patients were derived from the Human Protein Atlas (HPA) database. Further, survival analysis was evaluated with Kaplan-Meier Plotter. BC genome atlas data were obtained from cBioPortal databases. Gene regulatory network analysis was performed using the STRING online tool, and gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using DAVID. Results : Based on multiple database analysis, mRNA and protein levels of MCM2 , MCM4 and MCM10 were much higher in BC patient, and survival analysis showed that high transcription levels of most MCMs were found to be associated with poor prognosis for BC patients; moreover, the MCMs genetic alterations, especially of MCM2 , MCM4 and MCM10 , were found in 45% of BC patients. In addition, dysregulation of MCMs was considered to possibly affect DNA damage/repair, cell cycle dysregulation and chromosome instability. Conclusions : In summary, this study indicated that MCM2 , MCM4 , and MCM10 are potential prognostic markers and therapeutic targets for BC.","PeriodicalId":11903,"journal":{"name":"European journal of gynaecological oncology","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46815122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current treatment methods include debulking surgery with chemotherapy, however even with treatment, the five-year survival rate is below 45%. Cancer immunotherapy is an innovative treatment option being highly researched. Interleukins (ILs) are signaling molecules used by the human immune system to assist in detecting and destroying cancer cells. The ability of tumor cells to evade the immune system is a major challenge we face in fighting cancer. Ox40L/Ox40 and 4-1BBL/4-1BB are key immune costimulatory molecules that increase T cell activation to eliminate tumors. Past research has shown that IL9 has unique influences on various types of cancer, however, its role in ovarian cancer has not yet been assessed. In this study, ovarian cancer cells were treated with IL9 and the expression of Ox40L and 4-1BBL were measured. Methods : A2780 ovarian cancer cells were treated with IL9. Proliferation of ovarian cancer cells was measured by a Clonogenic Survival Assay and Quick Proliferation Assay. RT-PCR was conducted to determine whether IL9 upregulated the costimulatory molecules Ox40L and 4-1BBL. IHC was performed to further investigate IL9 upregulation of Ox40L and 4-1BBL. Results : Treatment of A2780 ovarian cancer cells with IL9 resulted in decreased proliferation of the ovarian cancer cells. By using RT-PCR, it was determined that IL9 treated ovarian cancer cells displayed upregulation of the costimulatory molecules Ox40L and 4-1BBL. Upregulation of OX40L and 4-1BBL was further confirmed by IHC. Conclusions : IL9 inhibited growth of ovarian cancer cells, and IL9 upregulated the key immune costimulatory molecules Ox40L and 4-1BBL. This suggests that increased expression of Ox40L and 4-1BBL may be associated with the inhibitory effect of IL9 on proliferation of ovarian cancer. This study warrants further investigation of the role of Ox40L and 4-1BBL in ovarian cancer growth.","PeriodicalId":11903,"journal":{"name":"European journal of gynaecological oncology","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49573232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By performing a literature review, we aim to highlight both the current treatment of malignant dysgerminoma and unanswered questions in the modern management of this disease.

Data on the efficacy of HIPEC in the primary debulking surgery (PDS) setting are still controversial and limited by the small sample size of most of the studies, the inclusion of different treatment settings and chemotherapy regimens. Among the ongoing prospective trials, only the OVHIPEC-2 trial is investigating exclusively patients submitted to PDS ± HIPEC with cisplatin 100 mg/m 2 and results are expected by 2026. On the interval debulking surgery (IDS) setting high quality data are coming from the result of the OVHIPEC-1 trial, which demonstrated a survival advantage of nearly 4 months in median progression-free survival (PFS) (14.2 months vs . 10.7 months; p = 0.003) and almost 12 months in median overall survival (OS) (45.7 months vs . 33.9 months; p = 0.02) for HIPEC treated patients (cisplatin 100 mg/m 2 ) compared to no-HIPEC group, with comparable morbidity. However, due to some criticisms raised to the results of OVHIPEC-1 trial, the ESMO-ESGO guidelines recommended not to consider HIPEC as standard therapy until results from ongoing randomized control trials (RCTs) are provided. On the contrary, for the National Comprehensive cancer network (NCCN) guidelines HIPEC can be considered at the time of IDS. Similarly, data supporting the role of HIPEC in association with surgery in case of recurrent disease appear to be controversial in terms of patients and selection and intraperitoneal chemotherapy regimen. Indeed, despite the positive results coming from a prospective randomized trial, they appear to be biased by the inclusion of both platinum sensitive and resistant disease and the lack of information on PFS. Those results are in contrast with data coming from another prospective trial, which failed to demonstrate a survival gain of recurrent ovarian cancer patients treated with secondary cytoreductive surgery + HIPEC with carboplatin (800 mg/m 2 for 90 min) compared to women submitted to cytoreduction only. Again, in this subgroup of patients data of ongoing RCTs are awaited to assess the impact on survival of HIPEC administration in case of recurrent disease.","PeriodicalId":11903,"journal":{"name":"European journal of gynaecological oncology","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48018803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
