Can we triumph over locally advanced cervical cancer with colossal para-aortic lymph nodes? A case report

BACKGROUND Para-aortic lymph nodes(PALNs)are common sites for the regional spread of cervical squamous cell carcinoma(SCC).CASE SUMMARY We report the case of a 36-year-old woman who presented with cervical SCC with multiple bulky PALNs,largest measured 4.5 cm×5 cm×10 cm.The patient was treated with radical intent with definitive chemoradiation using sequential doseescalated adaptive radiotherapy,followed by maintenance chemotherapy.The patient achieved a complete response;she has been doing well since the completion of treatment with no evidence of the disease for 2 years.CONCLUSION Regardless of the size of PALN metastases of cervical carcinoma origin,it is still treatable(with radical intent)via concurrent chemoradiation.Adaptive radiotherapy allows dose escalation with minimal toxicity.

Radical Hysterectomy in Cervical Cancer: Patients’ Epidemiological and Clinical Profiles and Perioperative Outcome in Two Referral Hospitals in Cameroon

Background: Cervical cancer (CC) is one of the most frequent cancers and the leading cause of death from gynecological cancer in Low and middle income countries, Cameroon inclusive. Surgery is the primary treatment modality when the disease is diagnosed at early stage. Radical hysterectomy in cervical cancer has not been evaluated in recent years in Cameroon. The purpose of this study is thus to evaluate the epidemiological and clinical features and short term outcomes of patients who underwent surgery. Patients and methods: This retrospective study was conducted at the Douala Gynaeco-obstetric and Pediatric Hospital and the Douala General Hospital. Cervical cancer patients who underwent Radical hysterectomy between January 2015 and December 2020 were included. A pre-established data collection tool was used to record socio-demographic, clinical and outcomes information from patients’ files;additional outcome information was obtained from phone calls. Descriptive analysis was done using the SPSS version 26. Bivariate analysis was used to determine associations between disease and patients characteristics and occurrence of adverse postoperative outcome. P value of 0.05 was considered. Results: Sixty one patients were enrolled. Their ages ranged from 33 to 74 years with a mean age of 51.95 ± 10.29 years. Over 85% of women were married, 65.57% were unemployed and 86.88% were multiparous. Only 28% had never done cervical cancer screening. Most patients had stage IB1 to IB2 stage disease (57.1%). Less than 9% underwent radical hysterectomy and 8 of those (13.11%) suffered intraoperative complications. Twenty-five patients (40.98%) presented immediate and short term complications. There was no significant association between the disease or patients’ characteristics and adverse outcomes. Conclusion: Cervical cancer patients are relatively young in our settings and only 9% of them reach the hospital at early stage. Postoperative adverse outcomes rate is higher than that reported in the literature. Sensitization on screening and awareness of early symptoms can reverse the situation.

Cervical cancer with transferrin receptor has a poor prognosis and is associated with immune infiltration, according to a comprehensive bioinformatics study

Background:The molecular mechanism underlying the involvement of the Transferrin receptor(TFRC)in cervical cancer remains poorly understood.This study aims to elucidate the role of TFRC in cervical cancer by analyzing data from The Cancer Genome Atlas(TCGA)and Genotype-Tissue Expression(GTEx)databases.Methods:TFRC protein expression was obtained from Human Protein Altas(HPA).All datas were collected from TCGA and GTEx.In this study,we analyzed the expression of TFRC in cervical cancer and its clinical significance.Through Kyoto Encyclopedia of Genes and Genomes(KEGG)and Gene set enrichment analyses(GSEA),investigated the related molecular pathways of TFRC.The relationship between TFRC and immune infiltration was then examined.The prognosis of different immune cell subsets was then analyzed after dividing cervical cancer patients into high and low expression of TFRC groups.Results:TFRC is highly expressed in various tumor tissues compared to control normal tissues,including cervical cancer.An increased expression of TFRC was associated with higher Tumor(T)and Node(N)stage,as well as a higher clinical stage.Kaplan–Meier(KM)survival analysis investigated that higher TFRC expression patients have a poor overall survival(OS),disease specific survival(DSS)and progress free interval(PFI).Both KEGG and GSEA enriched signaling pathway by high TFRC and low TFRC groups.There was a significant negative linear correlation between TFRC expression and immune infiltration.TFRC affects the prognosis of cervical cancer patients through immune pathway.Conclusions:Cervical cancer patients with TFRC expression may have a worse prognosis.

Cervical Cancer Prevention Challenges and Barriers to Cervical Cancer Screening and HPV Vaccinations in Ukraine and Eastern Europe

Objectives: To identify the obstacles and issues that hinder effective cancer prevention efforts in Ukraine. The study aims to provide a comprehensive assessment of the barriers to cancer prevention, including both infrastructure and behavioral factors, and identify potential solutions to address these challenges. Study Design: Comprehensive literature review. Methods: The following databases were searched: National Center for Biotechnology Information (NCBI) and PubMed (U.S. National Library of Medicine at the National Institutes of Health). The keywords used in the search included “Cervical Cancer”, “Human Papillomavirus Vaccination (HPV)”, “Ukraine”, “Eastern Europe”, “Healthcare Infrastructure in Disasters”, “Cervical Cancer Prevention”, “Pap Smear”, and “HPV Testing”. Results: A total of 3500 articles were screened. A total of 65 articles met the inclusion criteria. Limited public awareness and limited access to vaccination and screening, combined with inadequate treatment facilities lead to higher rates of cervical cancer. The COVID pandemic, war with Russia, and the Chernobyl disaster are significant factors for the low level of vaccination in Ukraine. Conclusion: The prevention and treatment of cervical cancer in Ukraine face significant challenges due to the inadequate HPV vaccination rates and screening by cytology. Efforts to improve funding and increase education of both the population and health care providers are necessary to increase interventions such as HPV vaccination, cervical cytology, and HPV testing to reduce cervical cancer rates in Ukraine.

The role of nurses in the prevention of cervical cancer: Cervical screening, an unkept promise by the majority of women in Nigeria

Cervical cancer remains a major public health problem accounting for continuous female death in developing countries.Cervical cancer is the second most common cancer in women globally with an estimated number of 500,000 new cases of cervical cancer and 273,000 mortalities annually.Cervical screening is the best cancer screening test in the history of medicine and most cost-effective of all medical screening tests.The study review aimed to highlight methods of cervical cancer prevention,identify the uptake of cervical screening among women,and explain the role of nurses in uptake of cervical screening.Cervical cancer is preventable and easily treatable if it is detected at early stages,but poor information on prevention and access to screening and treatment contributes to 90%of deaths.In the developing countries such as Nigeria,a large proportion of cervical cancers are diagnosed in advanced stages,with poor rates of survival.The three main methods for preventing cervical cancer are through primary prevention(human papillomavirus vaccination and health education),secondary prevention(cervical screening,early detection of precancerous lesions,and treatment),and tertiary prevention(measures to slow the progression or recurrence,surgical removal,radiotherapy,and chemotherapy).Nurses can help improve the acceptability of this neglected promise by focusing on health education on cervical screening and vaccination in prenatal clinics and infant welfare clinics where there are more women.Inclusion of cyberspace could also serve as a successful and popular platform for this health teaching.All nurses/midwives must preach and fervently work toward the WHO 90–70–90 plan for eradicating cervical cancer.

Perceived Barriers to Cervical Cancer Screening Using Pap Smear Test among Women Attending Saad Abu Al Ella Hospital in Khartoum State, 2022

Background: Cervical cancer is the second common cancer among women worldwide. It is a preventable cancer, and early detection of precancerous conditions through the Papanicolaou cytology screening (Pap smear) is a key aspect of prevention;it is accepted worldwide as an efficient tool for secondary prevention. While the PS test is simple, inexpensive, and relatively reliable as a method of diagnosing cervical cancer, most women do not take the test. Therefore, this study is sought to describe the barriers to pap smear uptake among Sudanese women. Materials and Method: This total coverage observational, analytical and cross sectional, hospital-based study was conducted in Saad Abu El Ella Hospital in April 2022. The study was conducted using an anonymous questionnaire to assess the perceived barriers of 93 participants. All data were computerized using Microsoft Excel’17 and the data were described and analyzed using statistical package for social science (SPSS23). Results: The findings revealed that the mean age of the participants was 39.5 years and only 3.2% had ever undergone a pap smear test. Identified barriers were lack of information, not knowing where to go, and fear of pain. The majority, 72% are willing to routinely perform a pap smear test if well informed about it. The study also demonstrates that there is a significant correlation between perceived barriers score and willingness to perform the pap smear test (p value = 0.008), and between the perceived barriers score and the sociodemographic factors: Age (p value = 0.006), educational level (p value = 0.028) and occupation (p value = 0.040), but no association with the economic status was found (p value = 0.378). Conclusion: The detection rate is too low compared to the national target of over 70%. Therefore, more work is needed to reduce perceived barriers to cervical cancer screening by providing education/raising for popular awareness;addressing misconceptions and false beliefs;informing women about the necessity and importance of Pap smear;and health promotion using mass media such as national television, social media, radio, billboards, and newspapers and other print media.

Establishment of a prediction model for severe acute radiation enteritis associated with cervical cancer radiotherapy

BACKGROUND Cervical cancer is one of the most common gynecological malignant tumors.Radiation enteritis(RE)leads to radiotherapy intolerance or termination of radiotherapy,which negatively impacts the therapeutic effect and seriously affects the quality of life of patients.If the incidence of RE in patients can be predicted in advance,and targeted clinical preventive treatment can be carried out,the side effects of radiotherapy in cervical cancer patients can be significantly reduced.Furthermore,accurate prediction of RE is essential for the selection of individualized radiation dose and the optimization of the radiotherapy plan.AIM To analyze the relationships between severe acute RE(SARE)of cervical cancer radiotherapy and clinical factors and dose-volume parameters retrospectively.METHODS We included 50 cervical cancer patients who received volumetric modulated arc therapy(VMAT)from September 2017 to June 2018 in the Department of Radiotherapy at The First Affiliated Hospital Soochow University.Clinical and dose-volume histogram factors of patients were collected.Logistic regression analysis was used to evaluate the predictive value of each factor for SARE.A nomogram to predict SARE was developed(SARE scoring system≥3 points)based on the multiple regression coefficients;validity was verified by an internal verification method.RESULTS Gastrointestinal and hematological toxicity of cervical cancer VMAT gradually increased with radiotherapy and reached the peak at the end of radiotherapy.The main adverse reactions were diarrhea,abdominal pain,colitis,anal swelling,and blood in the stool.There was no significant difference in the incidence of gastrointestinal toxicity between the radical and postoperative adjuvant radiotherapy groups(P>0.05).There were significant differences in the small intestine V_(20),V_(30),V_(40),and rectal V40 between adjuvant radiotherapy and radical radiotherapy after surgery(P<0.05).Univariate and multivariate analyses revealed anal bulge rating(OR:14.779,95%CI:1.281-170.547,P=0.031)and disease activity index(DAI)score(OR:53.928,95%CI:3.822-760.948,P=0.003)as independent predictors of SARE.CONCLUSION Anal bulge rating(>0.500 grade)and DAI score(>2.165 points)can predict SARE.The nomogram shows potential value in clinical practice.

Tra2βEnhances Cell Proliferation by Inducing the Expression of Transcription Factor SP1 in Cervical Cancer

Objective In this study,the role and potential mechanism of transformer 2β(Tra2β)in cervical cancer were explored.Methods The transcriptional data of Tra2βin patients with cervical cancer from Gene Expression Profiling Interactive Analysis(GEPIA)and cBioPortal databases were investigated.The functions of Tra2βwere evaluated by using Western blot,MTT,colony formation,Transwell assays,and nude mouse tumor formation experiments.Target genes regulated by Tra2βwere studied by RNA-seq.Subsequently,representative genes were selected for RT-qPCR,confocal immunofluorescence,Western blot,and rescue experiments to verify their regulatory relationship.Results The dysregulation of Tra2βin cervical cancer samples was observed.Tra2βoverexpression in Siha and Hela cells enhanced cell viability and proliferation,whereas Tra2βknockdown showed the opposite effect.Alteration of Tra2βexpression did not affect cell migration and invasion.Furthermore,tumor xenograft models verified that Tra2βpromoted cervical cancer growth.Mechanically,Tra2βpositively regulated the mRNA and protein level of SP1,which was critical for the proliferative capability of Tra2β.Conclusion This study demonstrated the important role of the Tra2β/SP1 axis in the progression of cervical cancer in vitro and in vivo,which provides a comprehensive understanding of the pathogenesis of cervical cancer.

Primary Treatment for Clinically Early Cervical Cancer with Lymph Node Metastasis:Radical Surgery or Radiation?

Objective To compare survival outcomes between primary radical surgery and primary radiation in early cervical cancer.Methods Patient information was extracted from the Surveillance,Epidemiology,and Results database.Patients diagnosed with early cervical cancer of stage T1a,T1b,and T2a(American Joint Committee on Cancer,7th edition)from 1998 to 2015 were included in this study after propensity score matching.Overall survival(OS)was analyzed using the Kaplan-Meier method.Results Among the 4964 patients included in the study,1080 patients were identified as having positive lymph nodes(N1),and 3884 patients were identified as having negative lymph nodes(N0).Patients with primary surgery had significantly longer 5-year OS than those with primary radiotherapy in both the N1 group(P<0.001)and N0 group(P<0.001).In the subgroup analysis,similar results were found in patients with positive lymph nodes of stage T1a(100.0%vs.61.1%),T1b(84.1%vs.64.3%),and T2a(74.4%vs.63.8%).In patients with T1b1 and T2a1,primary surgery resulted in longer OS than primary radiation,but not in patients with T1b2 and T2a2.In multivariate analysis,the primary treatment was identified as an independent prognostic factor in both N1 and N0 patients(HR_(N1)=2.522,95%CI=1.919–3.054,PN1<0.001;HR_(N0)=1.895,95%CI=1.689–2.126,PN0<0.001).Conclusion In early cervical cancer stage T1a,T1b1,and T2a1,primary surgery may result in longer OS than primary radiation for patients with and without lymph node metastasis.

Estimation of economic burden throughout course of cervical squamous intraepithelial lesion and cervical cancer in China:A nationwide multicenter cross-sectional study

Objective: Cervical squamous intraepithelial lesion(SIL) and cervical cancer are major threats to females' health and life in China, and we aimed to estimate the economic burden associated with their diagnosis and treatment.Methods: A nationwide multicenter, cross-sectional, hospital-based survey was conducted in 26 qualified hospitals across seven administrative regions of China. We investigated females who had been pathologically diagnosed with SIL and cervical cancer, and included five disease courses(“diagnosis”, “initial treatment”,“chemoradiotherapy”, “follow-up” and “recurrence/progression/metastasis”) to estimate the total costs. The median and interquartile range(IQR) of total costs(including direct medical, direct non-medical, and indirect costs), reimbursement rate by medical insurance, and catastrophic health expenditures in every clinical stage were calculated.Results: A total of 3,471 patients in different clinical stages were analyzed, including low-grade SIL(LSIL)(n=549), high-grade SIL(HSIL)(n=803), cervical cancer stage ⅠA(n=226), ⅠB(n=610), ⅡA(n=487), ⅡB(n=282), Ⅲ(n=452) and Ⅳ(n=62). In urban areas, the estimated total costs of LSIL and HSIL were $1,637.7(IQR:$956.4-$2,669.2) and $2,467.1(IQR:$1,579.1-$3,762.3), while in rural areas the costs were $459.0(IQR:$167.7-$1,330.3) and $1,230.5(IQR:$560.6-$2,104.5), respectively. For patients with cervical cancer stage ⅠA,ⅠB, ⅡA, ⅡB, and Ⅲ-Ⅳ, the total costs were $15,034.9(IQR:$11,083.4-$21,632.4), $19,438.6(IQR:$14,060.0-$26,505.9), $22,968.8(IQR:$16,068.8-$34,615.9), $26,936.0(IQR:$18,176.6-$41,386.0) and $27,332.6(IQR:$17,538.7-$44,897.0), respectively. Medical insurance covered 43%-55% of direct medical costs for cervical cancer patients, while the coverage for SIL patients was 19%-43%. For most cervical cancer patients, the expense was catastrophic, and the extent of catastrophic health expenditure was about twice large for rural patients than that for urban patients in each stage.Conclusions: The economic burden of SIL and cervical cancer in China is substantial, with a significant proportion of the costs being avoidable for patients with LSIL. Even for those with medical insurance, catastrophic health expenditures are also a major concern for patients with cervical cancer, particularly for those living in rural areas.

Early-Stage Cervical Cancerous Cell Detection from Cervix Images Using YOLOv5

Cervical Cancer(CC)is a rapidly growing disease among women throughout the world,especially in developed and developing countries.For this many women have died.Fortunately,it is curable if it can be diagnosed and detected at an early stage and taken proper treatment.But the high cost,awareness,highly equipped diagnosis environment,and availability of screening tests is a major barrier to participating in screening or clinical test diagnoses to detect CC at an early stage.To solve this issue,the study focuses on building a deep learning-based automated system to diagnose CC in the early stage using cervix cell images.The system is designed using the YOLOv5(You Only Look Once Version 5)model,which is a deep learning method.To build the model,cervical cancer pap-smear test image datasets were collected from an open-source repository and these were labeled and preprocessed.Then the YOLOv5 models were applied to the labeled dataset to train the model.Four versions of the YOLOv5 model were applied in this study to find the best fit model for building the automated system to diagnose CC at an early stage.All of the model’s variations performed admirably.The model can effectively detect cervical cancerous cell,according to the findings of the experiments.In the medical field,our study will be quite useful.It can be a good option for radiologists and help them make the best selections possible.

RASAL2 acts as a tumor suppressor in cervical cancer cells

This study was designed to investigate the roles of RASAL2 in cervical cancer(CC).Methods:Fifty-four CC tissues and 33 adjacent tissues were obtained from CC patients admitted to our hospital between March 2012 and June 2014.Real-time polymerase chain reaction and western blotting were performed to analyze the expression of RASAL2 mRNA and protein in these tissues,CC cell lines,and normal cervical cells.Over-expression and silencing of RASAL2 were induced after transfection,and the migration,invasion,and proliferation of the CC cell lines were examined.Results:RASAL2 mRNA and protein expressions were significantly down-regulated in CC tissues and cell lines than in adjacent tissues and normal cervical cells,respectively.While low RASAL2 expression correlated with advanced stage and metastasis of CC,its over-expression significantly inhibited proliferation and metastasis of CC cells and induced apoptosis.Under in vitro conditions,silencing of RASAL2 expression could significantly increase the proliferation,invasion,and migration of CC cells.Conclusion:RASAL2 functioned as a tumor suppressor in CC,and was down-regulated in CC tissue samples and cell lines.

SMC1A served as a potential therapeutic target to regulate malignant phenotypes of cervical cancer

Introduction:Structural maintenance of chromosome 1A(SMC1A)is a crucial compound of the cohesin complex.It has been reported to regulate the epithelial-mesenchymal transition(EMT)process in multiple cancers.Objectives:The present study aims to further clarify the role of SMC1A in cervical cancer.Methods:We analyzed data from four datasets and confirmed that SMC1A showed high expression in cervical cancer samples and was related to poor prognosis of patients with cervical cancer.Cell proliferation of SiHa and C-33A with knockdown of SMC1A was assessed using CCK-8 and colony formation assay.The migration and invasion were estimated by wound healing assay and Transwell assay separately.The effect of SMC1A on the chemosensitivity of cisplatin and paclitaxel in cervical cancer cells was detected by flow cytometry assay.Results:Results of the immunohistochemistry(IHC)assay confirmed that the expression of SMC1A was increased in tumor tissues.The cell viability was remarkably suppressed in SiHa and C-33A by knocking down the expression of SMC1A.The increase of E-cadherin expression and decrease of N-cadherin and Snail expression verified that inhibition of SMC1A suppressed the EMT process of cervical cancer cells.Further,cell migration,and invasion were significantly repressed by the absence of SMC1A.Cisplatin and paclitaxel are effective chemotherapeutic agents used in the treatment of cervical cancer.Silencing of SMC1A remarkably promoted the apoptosis induced by cisplatin and paclitaxel,revealing that the chemotherapy resistance to cisplatin and paclitaxel in cervical cancer could reduce by knocking down SMC1A.Further,metastasis associated with colon cancer 1(MACC1)was identified as the downstream factor of SMC1A.Its upregulation reversed the proliferation and the EMT process induced by SMC1A silencing.Conclusion:Therefore,our study concluded that SMC1A serves as a therapeutic molecular target to regulate the malignant phenotypes of cervical cancer.

Clinical implication of naive and memory T cells in locally advanced cervical cancer:A proxy for tumor biology and short-term response prediction

Background:This study was designed to investigate the feasibility of tumor-infiltrating immune cells with different phenotypic characteristics for predicting short-term clinical responses in patients with locally advanced cervical cancer(LACC).Methods:Thirty-four patients who received concurrent chemoradiotherapy and twenty-one patients who merely underwent radiotherapy were enrolled in this study.We retrospectively analyzed the T cell markers(i.e.,CD3,CD4,CD8),memory markers(i.e.,CD45,CCR7),and differentiation markers(i.e.,CD27)in the peripheral blood and tumor tissues of patients with LACC before treatment based on flow cytometry.We also analyzed the relationship of T cell subsets between peripheral blood and tumor tissues,and their correlation with complete response or partial response.Results:The percentage of central memory CD8^(+)TCM(CD8^(+)CD45RA^(−)CD27^(+)CCR7^(+))cells in LACC patients was significantly lower than that of the control group.The percentage of CD8^(+)TN in the peripheral blood of LACC patients was significantly higher than that of tumor tissues.CD8^(+)TEM in the peripheral blood was significantly lower than that of tumor tissues.The percentage of CD8^(+)TN and CD8^(+)TCM in human papillomavirus(HPV)positive samples was significantly higher than that of HPV-negative samples.Similarly,the percentage of CD8^(+)TCM in tumor tissues was significantly higher in cancer tissue samples with lymph nodes compared with those without.Conclusion:A higher proportion of CD4^(+)TCM and a lower proportion of CD8^(+)TN in the tumor microenvironment of LACC may contribute to the therapy response prediction.

Cervical Cancer Detection Based on Novel Decision Tree Approach

Cervical cancer is a disease that develops in the cervix’s tissue.Cervical cancer mortality is being reduced due to the growth of screening programmers.Cervical cancer screening is a big issue because the majority of cervical cancer screening treatments are invasive.Hence,there is apprehension about standard screening procedures,as well as the time it takes to learn the results.There are different methods for detecting problems in the cervix using Pap(Papanico-laou-stained)test,colposcopy,Computed Tomography(CT),Magnetic Reso-nance Image(MRI)and ultrasound.To obtain a clear sketch of the infected regions,using a decision tree approach,the captured image has to be segmented and analyzed.The goal of creating a decision tree is to establish prediction model that anticipate the feature vector based on the input variable.This paper deals with investigating various techniques of segmentation for detecting the cervical cancer.It proposes a novel method to develop an assistance system for the detection diag-nosis of cervical cancer,based on work of Martin,Byriel and Norup.The analysis is focused on Pap smear pictures of single cells.Smear testing is a method of detecting abnormalities in the blood.Image processing is an effective method for extracting data.It is used to determine the size of cervical carcinoma and the length of the uterus.Martin’s database,which is open source and utilised for analysis and valida-tion,is obtainable for research purposes.Cervical malignancy information utilizing three grouping strategies to anticipate the disease and afterward analyzed the out-comes showed that choice tree is the best classifier indicator with the test dataset.Further investigations ought to be led to improve execution.

Pre Screening of Cervical Cancer Through Gradient Boosting Ensemble Learning Method

In recent years,cervical cancer is one of the most common diseases which occur in any woman regardless of any age.This is the deadliest disease since there were no symptoms shown till it is diagnosed to be the last stage.For women at a certain age,it is better to have a proper screening for cervical can-cer.In most underdeveloped nations,it is very difficult to have frequent scanning for cervical cancer.Data Mining and machine learning methodologies help widely infinding the important causes for cervical cancer.The proposed work describes a multi-class classification approach is implemented for the dataset using Support Vector Machine(SVM)and the perception learning method.It is known that most classification algorithms are designed for solving binary classification problems.From a heuristic approach,the problem is addressed as a multiclass classification problem.A Gradient Boosting Machine(GBM)is also used in implementation in order to increase the classifier accuracy.The proposed model is evaluated in terms of accuracy,sensitivity and found that this model works well in identifying the risk factors of cervical cancer.

Knockdown Annexin A8 inhibits the proliferation and invasion of cervical cancer cells

This study aimed to explore the expression,function,and molecular mechanism of ANXA8,the gene for annexin 8,in cervical cancer.Methods:The gene expression of the ANX family members in cervical cancer tissues was classified via The Cancer Genome Atlas(TCGA)database.The expression of ANXA8 in paracancerous tissues,cervical cancer tissues,and cell lines was identified by fluorescence quantitative polymerase chain reaction(PCR)and immunohistochemistry.The effects of ANXA8 knockdown on the cellular growth and cell invasion of cervical cancer were examined by MTT,clone-formation assay,scratch test,and Transwell assay.The effect of ANXA8 knockdown on the proliferative potency of cervical cancer cells was assessed through an in vivo nude-mouse tumor-formation test.The gene expression levels of Ki-67 and ANXA8 in tumor-bearing tissues were measured through Immunohistochemical analysis.Results:TCGA data analysis and fluorescence quantitative PCR exhibited significantly increased expression of ANXA8 in cervical cancer tissues.Further examination exhibited that ANXA8 was expressed exceedingly in cervical cancer tissue,and it was associated with lymph node metastasis,FIGO stage,degree of differentiation,and infiltration depth of cancer patients.Cell-function assays revealed that knocking down ANXA8 may substantially suppress the propagation,colony formation,invasion,and migration of cervical cancer cells.In vivo experiments demonstrated that ANXA8 knockdown had a substantial inhibitory effect on the propagation of cervical cancer cells in nude mice and inhibited the expression of Ki-67.Conclusion:ANXA8 is specifically and significantly upregulated within cervical cancer tissues.The knockdown of this gene showed remarkable outcomes,as evidenced by the substantial inhibition of cervical cancer cell proliferation in in vitro and in vivo experimentations.Therefore,ANXA8 is a potential target or a marker that can serve as a therapeutic or diagnostic tool for cervical cancer.

Immunotherapy in combination with chemotherapy for Peutz-Jeghers syndrome with advanced cervical cancer:A case report

BACKGROUND Peutz-Jeghers syndrome(PJS)is a rare autosomal dominant disorder,and female patients may develop gynecologic tumours.The prognosis for such patients is poor and the specific pathogenesis remains uncertain.Therefore,there are currently no uniform treatment options.CASE SUMMARY Herein,we introduce the case of a 45-year-old female who was diagnosed with PJS for 45 years and cervical cancer for 3 years.Postoperative pathological examination showed metastases in the right external iliac lymph nodes.The patient was initially treated with a combination of doxorubicin and carboplatin chemotherapy and pelvic magnetic resonance showed that the metastases had grown.Subsequently,we performed whole exome sequencing in this patient and identified the relevant causative gene.In addition to the chemotherapy regimen,sindilizumab was administered and the patient was followed up.After 4 cycles of treatment,the metastases were substantially reduced and were not enlarged after six months of follow-up.This case report suggests that patients with PJS combined with cervical cancer may have a sustained response to immunecombination chemotherapy regimens.CONCLUSION Clinicians should be aware of the importance of immunotherapy in patients with PJS combined with advanced cervical cancer.

m^(6)A modification promotes the proliferation and migration of cervical cancer and regulates the expression of PD-L1

Objective:To explore the effects of N6-methyladenine(m^(6)A)modification-related genes,methyltransferase 14(METTL14),and YTH domain family protein 1(YTHDF1),on the proliferation,migration and apoptosis capabilities of cervical cancer cells and investigate their correlation with programmed cell death-ligand 1(PD-L1)expression.Methods:The expression levels of METTL14,YTHDF1 and PD-L1 in cervical cancer tissues and normal cervical tissues were analyzed using immunohistochemistry.Small interfering RNA(siRNA)was used to knock down the expression of METTL14 and YTHDF1 genes in cervical cancer cells,and the knockdown efficiency was validated by real-time fluorescent quantitative PCR(qPCR).After knockdown of METTL14 and YTHDF1,cell proliferation was assessed by CCK-8 assay,cell migration was examined by Transwell assay,cell apoptosis was detected by flow cytometry,and PD-L1 mRNA and protein expression were evaluated using qPCR and Western blotting,respectively.Results:Immunohistochemistry results demonstrated high expression of METTL14,YTHDF1,and PD-L1 in cervical cancer tissues.Knockdown of METTL14 and YTHDF1 significantly inhibited the proliferation and migration capabilities of cervical cancer cells,increased apoptosis,and downregulated PD-L1 mRNA and protein expression levels.Conclusion:m^(6)A methylation modification can affect the proliferation,migration and apoptosis of cervical cancer cells by regulating the expression of PD-L1 in cervical cancer cells.
