Abstract
Gynecologic cancers are a significant health issue for women globally. Early detection and successful treatment of these tumors are crucial for the survival of female patients. Conventional therapies are often ineffective and harsh, particularly in advanced stages, necessitating the exploration of new therapy options. Nanotechnology offers a novel approach to biomedicine. A novel biosensor utilizing bionanotechnology can be employed for early tumor identification and therapy due to the distinctive physical and chemical characteristics of nanoparticles. Nanoparticles have been rapidly applied in the field of gynecologic malignancies, leading to significant advancements in recent years. This study highlights the significance of nanoparticles in treating gynecological cancers. It focuses on using nanoparticles for precise diagnosis and continuous monitoring of the disease, innovative imaging, and analytic methods, as well as multifunctional drug delivery systems and targeted therapies. This review examines several nanocarrier systems, such as dendrimers, liposomes, nanocapsules, and nanomicelles, for gynecological malignancies. The review also examines the enhanced therapeutic potential and targeted delivery of ligand-functionalized nanoformulations for gynecological cancers compared to nonfunctionalized anoformulations. In conclusion, the text also discusses the constraints and future exploration prospects of nanoparticles in chemotherapeutics. Nanotechnology will offer precise methods for diagnosing and treating gynecological cancers.

Abstract
Objective To develop an early warning system that enables accurate parametrial invasion (PMI) risk prediction in cervical cancer patients with early-stage. Methods We retrospectively collected 218 early-stage cervical cancer patients who were treated in Jingzhou Central Hospital from January 31, 2015, to January 31, 2023, and diagnosed with early stage cervical cancer by pathology. The prediction model training is achieved by randomly dividing 70% of the training queue population, with the remaining 30% used as the testing queue. Then, a prediction model based on machine learning algorithms (including random forest, generalized linear regression, decision tree, support vector machine, and artificial neural network) is constructed to predict the risk of PMI occurrence. Ultimately, the analysis of receiver operating characteristic curve (ROC) and decision curve analysis (DCA) is used to evaluate the predictive ability of various prediction models. Results We finally included radiomics-based candidate variables that can be used for PMI model. Multivariate logistic regression analysis showed that energy, correlation, sum entropy (SUE), entropy, mean sum (MES), variance of differences (DIV), and inverse difference (IND) were independent risk factors for PMI occurrence. The predictive performance AUC of five types of machine learning ranges from 0.747 to 0.895 in the training set and can also reach a high accuracy of 0.905 in the testing set, indicating that the predictive model has ideal robustness. Conclusion Our ML-based model incorporating GLCM parameters can predict PMI in cervical cancer patients with stage IB1 to IIA2, particularly the RFM, which could contribute to distinguishing PMI before surgery, especially in assisting decision-making on surgical scope.

Abstract
Key Clinical Message Uterine artery embolization demonstrated significant efficacy in the treatment of utero-cervical cancer. This minimally invasive procedure holds promise as a valuable adjunct therapy, potentially offering improved outcomes and reduced morbidity in select cases. Further research is warranted to validate its broader clinical utility. Abstract Vaginal bleeding is a common complication of Cervical cancer that can be considered a critical emergency. Conventional hemostatic treatments may occasionally help reduce the bleeding but are not an effective long-term solution. Uterine Artery Embolization, a minimally invasive intervention, can halt the bleeding, achieving hemostasis, while removing many of the complications that alternative interventions carry. We outline a case study of a patient with extensive vaginal bleeding who had uterocervical malignancy and talk about the benefits of uterine artery embolisation for therapeutic management.

Abstract
Male partner involvement strongly influences a woman's decision to undergo cervical cancer screening. Women of low socioeconomic status are disproportionately affected by cervical cancer. Women living in low-and middle-income countries often encounter resistance from their partners regarding participation in cervical cancer screening. The lack of men's support for sexual and reproductive health programs, including cervical cancer screening, creates a barrier to women's utilization of health services. To assess Ethiopian men's awareness, knowledge, perceptions, and attitudes toward cervical cancer screening and their support to their female partners during screening. A community-based cross-sectional survey was conducted from June 20, 2023, to August 04, 2023. A multistage sampling procedure was used to recruit 614 male survey participants. Descriptive statistics were used to summarize sociodemographic data. Univariate and multivariate regression analyses were performed to measure the associations between the dependent and independent variables. A p-value of less than 0.05 was considered statistically significant. In this survey, 58.5% (359) of participants supported their partners for cervical cancer screening. More than half 55.9% (343) of the participants had an awareness of cervical cancer disease and 47.2% (290) participants knew the risk factors associated with the development of cervical cancer. In addition to that, 66.8% (410) of men have a positive attitude towards screening and encourage their wives to get screened if they notice symptoms of cervical cancer. Regarding the perceptions of cervical cancer, 37.0% (227) of male participants believed that their female partners were at risk of developing the disease, while 38.3% (235) of men believed that cervical cancer screening was only necessary if the woman showed symptoms. Completion of higher education (AOR = 3.75, 95% CI 1.60-8.79, p = 0.002), living with other people (AOR = 0.09, 95% CI 0.03-0.29, p < 0.0001), not being tested for HIV (AOR = 0.26, 95% CI 0.10-0.74, p = 0.011), and having information about cervical cancer (AOR = 3.33, 95% CI 1.36-8.15, p = 0.009) were statistically significantly associated with men's support for their partners in cervical cancer screening. Men's awareness, knowledge, and perceptions of cervical cancer screening were low. On the other hand, men have a positive attitude towards screening and encourage their wives to get screened if they notice symptoms of cervical cancer. This survey will serve as a basis for the development of further strategies and action plans to promote and support male participation in cervical cancer screening in Ethiopia. This can be achieved through the development of strategic plans, including public campaigns, raising awareness among social and community leaders, involving non-governmental organizations focusing on women's health, and community education.

Abstract
AIM This study aimed to investigate the psychometric properties of the Turkish adaptation of The Cervical Cancer Knowledge Scale (CCKS-T). This scale was designed for the assessment of cervical cancer knowledge levels among women in the screening period. METHODS Research was conducted with 307 women aged 21-65 years, who satisfied the eligibility criteria and agreed to participate. Data were collected via an online survey conducted during July and August 2023, utilizing both a Descriptive Information Form and the CCKS-T. To confirm the validity of the scale, language and content validity assessments were conducted, in addition to confirmatory factor analysis. The scale's reliability was evaluated using Cronbach's alpha, item-total correlation analysis, and a test-retest analysis. The scale consisted of eight items. RESULTS The content validity index of the scale items was found to be 1.0 with excellent sensitivity. Confirmatory factor analysis showed that the item factor loadings varied between 0.31 and 0.81 and the model had a good fit (x2/df = 2.200; GFI = 0.96; CFI = 0.96; RMSEA = 0.063). Cronbach's alpha of the Turkish version of the scale was found to be 0.80. CONCLUSION The CCKS-T demonstrates both validity and reliability as an instrument for the assessment of Turkish women's knowledge about cervical cancer.

Abstract
Precancerous and cancerous lesions of the uterine cervix are known to be associated with Human Papillomavirus (HPV) infection. The screening of high-risk (HR)-HPV infection in the female population has led to the discovery of several cases of a double cervix, a congenital malformation that is very rare. The purpose of this study was to evaluate HR-HPV infections in women with a double cervix within the National Cervical Cancer Screening program of the Lazio region (Italy). From June 2021 to March 2024, a total of 142,437 samples were analyzed by Seegene's Anyplex TM II HR-HPV method, which identifies 14 HR-HPV genotypes. For each woman identified with a double cervix, two separate samples were taken from both cervices and analyzed separately. Twenty-seven women with a double cervix were identified (0.019%): 23 women were tested as negative for both cervices, while the remaining four (namely A, B, C, and D) resulted positive. By genotyping, the following results were obtained: (A) Both samples showed genotype 31; (B) one cervix was negative while the other showed genotype 58; (C) one cervix was positive for HPV 18 and 31 while for 18, 31, and 33 in the other; and (D) one cervix showed genotype 66 while the other carried the 66 and 68 genotypes. Double cervix is a very rare condition where the presence of HR-HPV genotypes is not homogeneous. As already described, our study confirms that different genotypes can be detected in double cervix malformation, suggesting the need to perform HPV screening on brushing samples from both cervices.

Abstract
Objective Isoleucyl-tRNA synthetase 2 (IARS2) is crucial for mitochondrial activity and function in cancer cells. Cervical cancer is a highly prevalent malignancy affecting the female reproductive system on a global scale. This research investigates the expression and potential roles of IARS2 in cervical cancer cells. Material and Methods Initially, we examined the IARS2 expression profile in cervical cancer cells using Western blot technique and quantitative reverse transcription polymerase chain reaction methodologies. Subsequently, cervical cancer cell models with IARS2 silencing and overexpression were constructed using Short Hairpin RNA (ShRNA) (IARS2) and pcMV-FLAG-IARS2, respectively. The impact of IARS2 silencing or overexpression on Hela cell mitochondrial membrane potential, mitochondrial complex I, adenosine triphosphate (ATP) levels, reactive oxygen species activity, viability, proliferation, migration, apoptosis-related proteins, and apoptosis levels was examined through fluorescence staining, enzyme-linked immunosorbent assay, cell counting kit-8 assay, Transwell experiments, Western blot technique, and Terminal deoxynucleotidyl transferase dUTP nick end labeling assay techniques. Results The expression of IARS2 is upregulated in cervical cancer cells. Silencing IARS2 with ShRNA (IARS2) disrupts mitochondrial function in cervical cancer cells, resulting in mitochondrial depolarization, heightened oxidative stress, suppression of mitochondrial complex I, and a decrease in ATP levels. Moreover, the depletion of IARS2 significantly impedes the viability, proliferation, and migration of cervical cancer cells, inducing apoptotic processes. In contrast, the overexpression of IARS2 augments the proliferation, migration, and ATP levels in cervical cancer cells. Conclusion IARS2 plays a pivotal role as a mitochondrial protein in fostering the growth of cervical cancer cells, presenting itself as an innovative target for tumor diagnosis and treatment.

Abstract
Introduction Good compliance of the management of abnormal results is important for effective cervical screening. This study investigated the rate of surveillance and follow-up outcomes for human papillomavirus (HPV)-positive women in cervical screening. Method Women on surveillance by repeat HPV testing were identified in a prospectively managed database. Data retrieved included women's age, country residence status, history of colposcopy, HPV-DNA status on the first and repeat tests, dates of follow-up during the 5 years since the initial screening, and histological diagnosis of cervical lesions. The main outcome measures were compliance rate for repeat HPV testing, regression and persistence rates of HPV subtypes, and detection rate of high-grade lesions (CIN2+). Results This analysis included 680 residents in the community, mean age 44.8 (95% confidence interval 20.1-69.5) years. The compliance rate of repeat testing was 28.2% at 12 months and, cumulatively, 42.8% for the entire 5-year follow-up period. The rates were unaffected by age (P=0.5829) nor prior colposcopy (P=0.1607). There were 5 (1.7%) cases of CIN2+ detected. Of 391 women on longitudi-nal follow-up, 194 (60.8%) cleared their HPV infection. Some women with multiple HPV infection cleared 1 but not the other subtype(s). Thus, the regression rate was 90.3% for HPV-16, 87.0% for HPV-18 and 65.2% for HPV-12-others (P=0.001). The annualised HPV regression rates were similar for HPV subtypes and for each follow-up year. Conclusion Surveillance of HPV positivity is clinically important for detecting high-grade lesions. Despite a high regression rate of HPV, surveillance hesitancy is a serious weakness in routine cervical screening.

Abstract
INTRODUCTION Cervical cancer presents a significant global health challenge, disproportionately impacting underserved populations with limited access to healthcare. Early detection and effective management are vital in addressing this public health concern. This study focuses on Glyoxalase-1 (GLO1), an enzyme crucial for methylglyoxal detoxification, in the context of cervical cancer. METHODS We assessed GLO1 expression in cervical cancer patient samples using immunohistochemistry. In vitro experiments using HeLa cells were conducted to evaluate the impact of GLO1 inhibition on cell viability and migration. Single-cell RNA sequencing (scRNA-seq) and gene set variation analysis were utilized to investigate the role of GLO1 in the metabolism of cervical cancer. Additionally, public microarray data were analyzed to determine GLO1 expression across various stages of cervical cancer. RESULTS Our analysis included 58 cervical cancer patients, and showed that GLO1 is significantly upregulated in cervical cancer tissues compared to normal cervical tissues, independent of pathological findings and disease stage. In vitro experiments indicated that GLO1 inhibition by S-p-bromobenzylglutathione cyclopentyl diester decreased cell viability and migration in cervical cancer cell lines. Analyses of scRNA-seq data and public gene expression datasets corroborated the overexpression of GLO1 and its involvement in cancer metabolism, particularly glycolysis. An examination of expression data from precancerous lesions revealed a progressive increase in GLO1 expression from normal tissue to invasive cervical cancer. CONCLUSIONS This study highlights the critical role of GLO1 in the progression of cervical cancer, presenting it as a potential biomarker and therapeutic target. These findings contribute valuable insights towards personalized treatment approaches and augment the ongoing efforts to combat cervical cancer. Further research is necessary to comprehensively explore GLO1's potential in clinical applications.

Abstract
With the escalating incidence and prevalence of cancer worldwide disproportionately affecting low- and middle-income countries, there is an urgent need for the global oncology community to foster bidirectional partnerships and an equitable exchange of knowledge, resources, and expertise. A dedicated Global Oncology Community of Practice (CoP) can serve as a self-organizing, grassroots approach for members, with common goals and values, to coordinate efforts, maximize impact, and ensure sustainable outcomes. It is imperative, however, when outlining goals and priorities to adhere to an ethical and appropriate framework during community building efforts to avoid perpetuating inequities and power imbalances. This article reviews the core guiding principles for ASCO's Global Oncology CoP which includes responsibility, amplification, accessibility, sustainability, and decolonization.

Abstract
OBJECTIVE Circular RNAs (circRNAs) are involved in the development of human cancers, including cervical cancer (CC). However, the role and mechanism of circ_0006789 (circSLC25A43) in CC are unclear. The purpose of this study was to investigate the functional role of circ_0006789 in CC. METHODS The expression of circ_0006789 in CC tissues and cell lines was examined by RT-qPCR. The characterization of circ_0006789 in CC cells was verified by subcellular localisation, actinomycin D assay, and RNase R assay. After circ_0006789 was knocked down in CC cell lines, the proliferation, apoptosis, migration and invasion of CC cells were assessed by CCK-8 method, flow cytometry, and Transwell assay. RIP assay, FISH assay, dual luciferase reporter gene assay and Western blot were used to investigate the regulatory mechanism between circ_0006789, miR-615-5p and heat shock factor 1 (HSF1). RESULTS circ_0006789 was upregulated in CC tissues and cell lines. CC cells were inhibited in their proliferation, migration, and invasion, as well as promoted to apoptosis when circ_0006789 was knocked down. It was found that circ_0006789 targeted miR-615-5p, and miR-615-5p expression was inversely correlated with circ_0006789 expression. Furthermore, HSF1 was a target gene of miR-615-5p. Furthermore, the suppressive effects on HeLa cells mediated by circ_0006789 knockdown were counter-balanced when miR-615-5p was knocked down and HSF1 was overexpressed. Mechanistically, circ_0006789 was found to promote CC development by reducing miR-615-5p and increasing HSF1 expressions. CONCLUSION circ_0006789 accelerates CC development via the miR-615-5p/HSF1 axis.

Abstract
CC (CC) remains a significant global health concern, imposing a substantial health burden on women worldwide due to its high incidence and mortality rates. To address this issue, there is a need for ongoing research to uncover the underlying molecular mechanisms of CC and to discover novel diagnostic and therapeutic strategies. Recent progress in non-coding RNAs (ncRNAs) has opened new avenues for investigation, and circular RNAs (circRNAs) have emerged as molecules with diverse roles in various cellular processes. These circRNAs are distinct in structure, forming a closed loop, setting them apart from their linear counterparts. They are intricately involved in regulating different aspects of cellular functions, particularly in cell growth and development. Remarkably, circRNAs can have varying functions, either promoting or inhibiting oncogenic processes, depending on the specific cellular context. Recent studies have identified abnormal circRNAs expression patterns associated with CC, indicating their significant involvement in disease development. The differing circRNAs profiles linked to CC present promising opportunities for early detection, precise prognosis evaluation, and personalized treatment strategies. In this comprehensive review, we embark on a detailed exploration of CC-related circRNAs, elucidating their distinct roles and providing insights into the intricate molecular mechanisms governing CC's onset and progression. A growing body of evidence strongly suggests that circRNAs can serve as valuable biomarkers for early CC detection and hold potential as therapeutic targets for intervention. By delving into the complex interplay between circRNAs and CC, we are paving the way for innovative, individualized approaches to combat this serious disease, with the goal of reducing its impact on women's health globally and improving patient outcomes. As our understanding of circRNAs in the context of CC continues to deepen, the outlook for breakthroughs in diagnosis and treatment becomes increasingly promising.

Abstract
BACKGROUND Human papilloma virus (HPV) infection among female is the cause of cervical cancer and genital warts. In China, the HPV vaccination rate and the target population screening rate among females are low, and the aims of this study on the genotype distribution and prevalence of HPV infection were to provide more targeted strategies for the prevention and treatment of cervical cancer and HPV-related diseases. METHODS Polymerase chain reaction-reverse dot blot (PCR-RDB) was adopted for HPV genotyping test, the prevalence and 23 genotypes distribution of HPV infections among 181,705 women in Chengdu from 2013 to 2020 were analysed. RESULTS The overall prevalence rate of HPV infection among 181,705 cases was 23.28%, the prevalence of HR-HPV at the age group < 20 years, 60-69 years and ≥ 70 years were higher than the overall prevalence.The prevalence of HPV showed a bimodal U-shaped curve with age; the first and second peak common occurred among females < 20 years old (42.97%) and 60-69 years old (37.56%), respectively.The top five genotypes of HPV infection among females in Chengdu were HPV52/16/58/81/53. Single infection (73.26%) was the main HPV infection pattern, followed by double infection (19.17%) and multiple infection (7.57%), the infection rate of HPV showed a gradual declined as the patterns of HPV coinfections increased, low-risk and high-risk coinfection was higher in low-risk HPV infection (43.68%) and lower in high-risk HPV infection (13.59%). The prevalence of genotypes - 6 and - 81 infection was the second highest at the age group of 20 and 40-59, respectively, while the prevalence of HPV16 was the highest at the age group of ≥ 70 among 23 genotypes among the 181,705 women. CONCLUSIONS The prevalence of HPV infections among women in Chengdu is higher than domestic certain developed citys, among the five vaccines available, nonavalent vaccine is more suitable for Chengdu females. For young females prioritizing vaccination is essential in the current context.Double screening for HPV DNA is important in middle-aged women (30-49 years), and screening should not be lacking in older women (> 65 years). Additionally,for patients with genital warts, it is necessary to screen for high-risk HPV infection and provide appropriate management and treatment. Given the limitations of this study, future HPV research should aim to achieve full coverage of the target population, and our studies should also include cellular or pathological data of HPV-positive cases, vaccination rates, and various lifestyle details.

Abstract
Artificial intelligence has yielded remarkably promising results in several medical fields, namely those with a strong imaging component. Gynecology relies heavily on imaging since it offers useful visual data on the female reproductive system, leading to a deeper understanding of pathophysiological concepts. The applicability of artificial intelligence technologies has not been as noticeable in gynecologic imaging as in other medical fields so far. However, due to growing interest in this area, some studies have been performed with exciting results. From urogynecology to oncology, artificial intelligence algorithms, particularly machine learning and deep learning, have shown huge potential to revolutionize the overall healthcare experience for women's reproductive health. In this review, we aim to establish the current status of AI in gynecology, the upcoming developments in this area, and discuss the challenges facing its clinical implementation, namely the technological and ethical concerns for technology development, implementation, and accountability.

[PMID: 38371520 PMCID: PMC10874123 DOI: 10.2147/ijgm.s453675] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 02/07/2024] [Indexed: 02/20/2024] Open
Abstract
Purpose Among the Organisation for Economic Co-operation and Development countries, Japan has one of the lowest cervical cancer screening coverages. Cancer screening coverage has worsened due to the coronavirus disease of 2019 (COVID-19) pandemic. This study investigated the relationship between socioeconomic background, COVID-19 infection history and vaccine status, and regular cervical cancer screening (CCS) during the two years of the COVID-19 era in Japan. Patients and Methods We used data from the Japan COVID-19 and Society Internet Survey, a nationwide, Internet-based, self-report cohort observational study conducted in 2022. The outcome variable was identified by asking whether the participants had undergone CCS within the last two years. Cervical cytology was performed in Japan by brushing the external cervical os. This study used multivariate log-binomial regression models to evaluate inequalities during regular checkups for CCS. Adjusted prevalence ratios (APRs) with 95% confidence intervals (CIs) were estimated to incorporate the socioeconomic background variables. Results Of the 12,066 participants, 5597 (46.4%) had undergone regular CCS for over two years. The prevalence ratio (PR) of patients who underwent CCS was 0.70 for those in their 20s and 0.78 for those in their 60s, compared to those in their 40s. Socioeconomic inequities were found in the following groups: unemployed/student, unmarried, high school graduate or lower, and household income below 4 million Yen. Our final multivariate analysis revealed that participants who were in their 20s or 60s, had a household income below 4 million Yen, were unmarried, had no annual health check-ups, and were unvaccinated with COVID-19 were at a higher risk of not undergoing CCS. Conclusion The relationship between socioeconomic inequality and CCS hesitancy is prevalent among younger participants. The CCS coverage in Japan during the COVID-19 pandemic year (2020-2022) was not low compared with the pre-pandemic era.

Abstract
Background Cervical cancer (CC) is currently the most common malignant tumour in the female reproductive tract, and paclitaxel (PTX) is a commonly used chemotherapeutic agent, but tumour cell resistance will seriously affect the therapeutic efficacy of PTX. Nanoparticle human serum albumin-bound paclitaxel (Nano-HSA-PTX) is a novel drug delivery modality that may have superior effects to PTX alone. Objective To clarify the effect of Nano-HSA-PTX on cervical carcinoma (CC) cells and the underlying mechanisms. Methods After the preparation of Nano-HSA-PTX, its morphology was observed by electron transmission microscope (TEM), and its entrapment efficiency (EE%) and drug loading rate (DL%) were detected. Nano-HSA-PTX was compared with conventional PTX for drug metabolism. Additionally, CC HeLa and SiHa cells were purchased and divided into three groups to treat with Nano-HSA-PTX, PTX and normal saline, respectively. MTT, cell cloning, Transwell and cell scratch assays were carried out to determine cell proliferation, invasion and migration, flow cytometry and Western blotting were performed to detect apoptosis rate and apoptosis-related protein expression, and PCR was conducted to quantify oxidative damage indicators. Further, CYP3A4 and CYP2C8 expression patterns in CC cells (HeLa and SiHa) and human normal cervical epithelia (End1/E6E7) and the changes of their levels under the intervention of Nano-HSA-PTX were measured. Subsequently, C57BL/6mice were purchased for subcutaneous tumorigenesis experiment to observe the impact of Nano-HSA-PTX on tumor growth. Results Under TEM, Nano-HSA-PTX was complete and arranged compactly, with a stable structure and markedly higher EE% and DL% than PTX (P < 0.05). Under Nano-HSA-PTX intervention, the proliferation, invasion, migration and oxidative damage of HeLa and SiHa were significantly decreased compared with the control and PTX groups, while the apoptosis was increased (P < 0.05). Besides, elevated CYP3A4 and CYP2C8 levels were observed in CC cells, which were inhibited by Nano-HSA-PTX and PTX (P < 0.05). Finally, tumorigenesis experiments in nude mice revealed that Nano-HSA-PTX could inhibit tumor growth. Conclusion Compared with PTX, Nano-HSA-PTX has a superior effect of inhibiting CC activity. And this mechanism of action was carried out by inhibiting the expression of CYP3A4 and CYP2C8.

Abstract
Objectives Effective reduction of cervical cancer incidence and mortality requires strategic measures encompassing the implementation of a cost-effective screening technology. Serbia has made significant strides, introducing organized cervical cancer screening in 2012. However, various impediments to screening implementation persist. The aim of the study was to estimate the socioeconomic factors associated with cervical cancer screening among women in Serbia. Methods Data from 2019 National Health Survey of the population of Serbia were used in this study. The study is cross sectional survey on a representative sample of the population of Serbia. Present total number of participants analyzed in survey 6,747. Results In Serbia, 67.2% of women have done a Pap test at any time during their lives, of which 46.1% of women have undergone cervical cancer screening in the past 3 years. About a quarter of women have never undergone a Pap test in their life (24.3%). The probability of never having a Pap test have: the youngest age group (15-24 years) is 1.3 times more likely than the oldest age group (OR = 1.31), unmarried women 0.3 times more often than married women (OR = 0.37), respondents with basic education 0.9 times more often than married women (OR = 0.98), the women of lower socioeconomic status 0.5 times more often than respondents of high socioeconomic status (OR = 0.56). Conclusion Enhancement of the existing CCS would be the appropriate public health approach to decrease the incidence and mortality of cervical cancer in the Republic of Serbia.

Abstract
INTRODUCTION Cervical cancer is one of the malignant cancers with high mortality among women worldwide. Although vaccines and early detection have reduced cervical cancer mortality, it remains a malignancy with a high mortality rate in women. OBJECTIVES We aimed to develop a novel integrated strategy that combines metabolomics with network pharmacology to explore the therapeutic mechanisms of naringin in cervical cancer. The mechanism of naringin intervention in cervical cancer was initially clarified by metabolomics and network pharmacology. METHODS The method of LC-MS and network pharmacology for the detection and identification of potential biomarkers and the mechanisms of action of naringin was used. The metabolites were detected and identified based on ultra-high-performance liquid chromatography coupled with Quadrupole- Exactive Orbitrap MS (UHPLC-Q-Exactive Orbitrap MS) and followed by the network pharmacology analysis. RESULTS In network pharmacology, naringin played a synergetic role through regulatory shared pathways, such as steroid hormone biosynthesis, sphingolipid signaling pathway and arachidonic acid metabolism, etc. Besides, the metabolomics analysis showed that 20 differential metabolites and 10 metabolic pathways were mainly involved in the therapeutic effect of naringin on cervical cancer. The result showed that naringin treatment for cervical cancer mainly occurs through the following metabolic pathways: amino acid metabolism and arachidonic acid metabolism. CONCLUSION This work provided valuable information and a scientific basis for further studies of naringin in the treatment of cervical cancer.

Changes in T lymphocyte subsets in peripheral blood of patients with middle-advanced cervical cancer before and after nimotuzumab combined with concurrent chemoradiotherapy. J OBSTET GYNAECOL 2023; 43:2179915.

Abstract
The current study sought to investigate the effect of nimotuzumab combined with concurrent chemoradiotherapy (CCRT + Nim) on T lymphocyte subsets in middle-advanced CC. Firstly, patients with middle-advanced CC were administered CCRT or CCRT + Nim. Next, levels of T lymphocytes in peripheral blood of CC patients pre- or post-treatment and healthy females were determined by flow cytometry. The short-term efficacy was evaluated, and overall survival (OS) and progression-free survival (PFS) of patients were recorded. In addition, the correlation of T lymphocyte subsets post-treatment with OS/PFS was assessed with Pearson analysis. CC patients exhibited decreased total T cells/T helper cells/CD4+/CD8+ ratio and increased T suppressor cells/Tregs in peripheral blood. Meanwhile, CCRT and CCRT + Nim improved T lymphocyte subset imbalance, with CCRT + Nim exhibiting better efficacy. CCRT + Nim exhibited better short-term efficacy and higher PFS than CCRT, with no evident difference in OS. The levels of total T cells/T helper cells/T suppressor cells/Tregs were not significantly-correlated with OS/PFS, and the CD4+/CD8+ ratio was correlated with PFS but not OS. Collectively, CCRT + nimotuzumab ameliorate the imbalance of T lymphocyte subsets in peripheral blood of middle-advanced CC patients, and the CD4+/CD8+ ratio after therapy is correlated with PFS.IMPACT STATEMENTWhat is already known on this subject? The utilisation of Nimotuzumab targeting epidermal growth factor receptor (EGFR) combined with concurrent chemoradiotherapy (CCRT) as an efficient treatment for middle-advanced cervical cancer (CC) has garnered the attention of numerous researchers over the years. T cells represent a major immune cell type in the tumour microenvironment and serve as the basis for maintaining cellular immune functions.What do the results of this study add? Our findings revealed that nimotuzumab combined with CCRT improves the abnormality of T lymphocyte subsets in peripheral blood of patients with middle-advanced CC, such that the CD4+/CD8+ ratio after treatment was significantly correlated with progression-free survival (PFS).What are the implications of these findings for clinical practice and/or further research? CCRT of CC may have a short-term negative impact on the peripheral T-cell immune micro-environment, and the combination of nimotuzumab, cisplatin-based chemotherapy, and radiotherapy enhances the frequency of Tregs in peripheral blood. Our findings illustrated that nimotuzumab combined with CCRT can improve the imbalance of T lymphocyte subsets in peripheral blood of patients with middle-advanced CC. A better understanding of the mechanisms of these therapies will optimise the selection of patients most likely to benefit from treatment, serving as a reference for further research on the relationship between EGFR-specific T cells and clinical benefit in patients treated with nimotuzumab in combination with CCRT.

Abstract
Cervical cancer (CC) is the most prevalent gynecological malignancy and a leading cause of death among women. It is primarily caused by human papillomavirus (HPV) infection, with 99.7% of cases showing high-risk HPV genotypes. This study sheds light on HPV dynamics as well as the discrepancies of different CC screening modalities results while highlighting factors that may have contributed to such a scenario. Moreover, we underscore the importance of the non-viral etiology of CC as well. We examined the current trends of HPV infection and its effects on cervical health in women treated at a tertiary care center in Belgrade, Serbia. Patients with abnormal colposcopy findings like dysplasia and re-epithelization were more likely to test negative for HPV (p < 0.001). Interestingly, women with a positive Pap smear tested HPV negative significantly more often (p = 0.041). Finally, HPV-positive individuals were more likely to have CIN I and II histologies (p < 0.001), while CIN III occurred equally in women with and without the virus. It may be inferred that inconsistencies in detecting HPV and the presence of cervical lesions may eventually result in adjustments to screening guidelines, as is crucial to adopt a meticulous approach to promote periodical CC screening, as initial samples may test negative for HPV.

Abstract
Cervical cancer (CC) is a very usual reproductive malignant tumor in women. RNA polymerase II-associated factor 1 (PAF1) and flotillin-2 (FLOT2) both have been discovered to key participators in cancers' progression. However, the effects of PAF1/FLOT2 axis on CC development have not been probed. In this study, PAF1 and FLOT2 exhibited higher expression, and silencing of PAF1 down-regulated FLOT2 expression in CC. In addition, the regulatory effects of PAF1 suppression on CC progression were reversed after FLOT2 overexpression. Next, inhibition of PAF1 slowed the tumor growth in vivo through modulating FLOT2. Besides, down-regulation of PAF1 reduced FLOT2 expression to retard the MEK/ERK1/2 pathway. In conclusion, knockdown of PAF1 suppressed CC progression via retarding FLOT2-mediated MEK/ERK1/2 pathway. Our findings illustrated that the PAF1/FLOT2 axis may be useful bio-targets for CC treatment.

Abstract
Cervical cancer (CvC) is considered a preventable disease; however, in the Caribbean, it is still one of the fourth most common causes of death in women. Efforts to overcome obstacles to the treatment and control of this preventable disease are being made by several countries within the Caribbean. However, no health issue can be readily managed without first acquiring an understanding of the dynamics relating to its severity of impact reaching the target population, its clinical pathology, and the availability of treatment and/or preventative measures to control or halt its progression. To assess the status of CvC in the Caribbean, a review of the literature was conducted using PubMed. The Caribbean was defined in the review as comprising nations and islands whose coastlines are touched by the Caribbean Sea. This led to an assessment of the available literature on CvC for 33 Caribbean territories. The review showed a lack of published information on CvC and highlights the need for greater research. This also serves as a template for subsequent investigations.

Abstract
Background Loop electrosurgical excision procedure (LEEP) conization and hysterectomy are performed for some patients with papillary squamous cell carcinoma (PSCC), whereas only hysterectomy is performed for others. We aimed to determine the optimal management for PSCC. Methods Patients diagnosed with PSCC by colposcopy-directed biopsy between June 2008 and January 2020 who underwent LEEP conization and hysterectomy or only hysterectomy at our hospital were enrolled. Results of cervical cytology, high-risk human papillomavirus testing, transvaginal sonography, pelvic magnetic resonance imaging, LEEP, hysterectomy, and pathology testing of colposcopy-directed biopsy samples were analyzed. Results A total of 379 women were diagnosed with PSCC by colposcopy-directed biopsy; 174 underwent LEEP before hysterectomy and 205 underwent only hysterectomy. Patients underwent and did not undergo LEEP were aged 47 ± 11 years and 52 ± 11 years, respectively. Among women who underwent LEEP, the agreement between LEEP and hysterectomy pathology was 85.1%. For women who underwent only hysterectomy, the agreement between preoperative clinical staging and pathological staging after hysterectomy was 82.4%. For patients with preoperative imaging indicative of malignancy, the accuracy of LEEP for diagnosing and staging PSCC was 88.5%, whereas for the hysterectomy-only group, it was 86.2%. For patients without malignancy detected with imaging, the accuracy of LEEP for diagnosing and staging PSCC was 81.6%; however, for those who did not undergo LEEP, it was 70.0%. Conclusion For women diagnosed with PSCC by colposcopy-directed biopsy, LEEP conization is necessary for an accurate diagnosis when imaging does not indicate cancer; however, LEEP is not necessary when imaging indicates cancer.

Abstract
BACKGROUND Cervical cancer is highly preventable. The mortality-to-incidence ratio (MIR) is a marker that reflects the available screening interventions and clinical outcomes of cancer treatments. The association between the MIR for cervical cancer and cancer screening disparities among countries is an interesting issue but rarely investigated. The present study sought to understand the association between the cervical cancer MIR and the Human Development Index (HDI). METHODS Cancer incidence and mortality rates were obtained from the GLOBOCAN database. The MIR was defined as the ratio of the crude mortality rate to the incidence rate. We used linear regression to analyze the correlation of MIRs with the HDI and current health expenditure (CHE) in 61 countries selected based on data quality. RESULTS The results showed lower incidence and mortality rates and MIRs in more developed regions. In terms of regional categories, Africa had the highest incidence and mortality rates and MIRs. The incidence and mortality rates and MIRs were lowest in North America. Furthermore, favorable MIRs were correlated with a good HDI and high CHE as a percentage of gross domestic product (CHE/GDP) (both p < 0.0001). CONCLUSIONS The MIR variation for cervical cancer is associated with the ranking of the health system and health expenditure, which further supports the role of cancer screening and treatment disparities in clinical outcomes. The promotion of cancer screening programs can reduce the cervical cancer global incidence and mortality rates and MIRs.

Abstract
RATIONALE Copious vaginal discharge is a frequent manifestation of reproductive tract infections. However, when little effect can obtain treated as vaginitis, cervical disease should be highly suspected. PATIENT CONCERNS A 41-year-old woman had suffering from abnormally increased vaginal discharge without any other signs of discomfort for the past 4 years. A lot of medical examinations and treatment of vaginosis were administered, resulting in unclear diagnosis and little effect. DIAGNOSES Cervical adenocarcinoma. INTERVENTIONS Gynecological examination, vaginal microbiome culture, and primary cervical cancer screening were negative, and a positron emission tomography revealed an increased 18F-fluorodeoxyglucose metabolism in the local cervix. After a thorough description, the patient demanded a hysterectomy and bilateral salpingo-oophorectomy. OUTCOMES Histopathological evaluation confirmed adenocarcinoma in situ of the uterine cervix. LESSONS The correct diagnosis of symptomatic patients with increased vaginal discharge is challenging. Human papillomavirus-negative patients presenting profuse watery vaginal discharge with an abnormal signal of cervix lesion on positron emission tomography or magnetic resonance imaging should be alert to cervical adenocarcinoma. Deep-seated cervical biopsy, conization, or even hysterectomy is conducive to early diagnosis, treatment and improvement of prognosis.

Abstract
OBJECTIVES To explore the relationship between cervical cancer burden and HDI and other socioeconomic influence factors in 127 countries. METHODS Dividing 127 countries into low-, medium-, high-, ultrahigh-HDI groups, and using statistical method to compare the prevalence trend of cervical cancer in different HDI country groups. Then selecting mortality-to-incidence ratio (MIR) to measure the cancer burden as the dependent variable, HDI and other socioeconomic factors selected from 2020 Human Development Report as independent variables, and using multi-regression model to analyze the correlation between variables. RESULTS Countries with higher HDI were found to have lower prevalence and mortality of cervical cancer, and vice versa. Besides that, air and water pollution, government-coordinated spending, and the intimate partner of 15-49-year-old women and girls have positive correlation impact on cervical cancer burden. DISCUSSION The cancer prevention and control policies in countries with high HDI have achieved relatively ideal implementation effects. Countries with relatively backward social and economic development level, cancer prevention and control policies had little effect, such as lower HPV vaccination coverage, poor regional health resource allocation, and week public education awareness. Therefore, cervical cancer control plan must be integrated into national strategies and implemented in people-oriented comprehensive health services.

Abstract
Global cervical cancer incidence and mortality have remained a major public health problem. Depending on the quality and coverage of preventive programs, and the capacity of health care systems, different screening tests are used, with the Pap smear being the most widely implemented. Several difficulties have been reported in accessing timely detection, causing late cervical cancer diagnosis. Trying to close these gaps, new screening devices have been developed in recent years; however, there is a lack of knowledge about whether or not women perspective has been included in the design process and technological development of these devices. This scoping review aimed to describe and synthesize scientific literature on women's critical experiences with Pap smears to prospectively contribute to the design, development, and scale-up of cervical cancer screening devices. The electronic databases Web of Science, Scopus, PubMed, PsycINFO and SciELO were searched for relevant studies published between 2012 and 2021; finally, 18 qualitative studies were included. Experiences were classified into four categories: fear and embarrassment, speculum pain and discomfort, outcome distress and health service barriers. Critical experiences before, during, and after the test were analyzed in turn. In particular, during the test, women reported pain associated with the use of the speculum. The acceptability of new screening devices will largely depend on comfort during the test and timely delivery of results. This review provides a useful qualitative synthesis, not only to advance the design of novel devices but also for future implementation research in cervical screening services.

Abstract
AIM Low- and middle-income countries represent nearly 85% of all cervical cancer cases worldwide; thereby, it is extremely important to identify methods to improve the screening process. Therefore, this study aimed to summarize the primary characteristics of studies on accessibility, coverage, patient preferences, and factors associated with patient satisfaction or acceptance of colposcopy in primary healthcare. METHODS A search strategy, based on MeSH, Emtree, and free terms, was run through 5 databases (PubMed, Scopus, Embase, Ovid/Medline, and Web of Science). EndNote 20.1 © and Rayyan QCRI © were used for screening. A preset datasheet was used for data extraction. RESULTS The systematic search retrieved 1127 references, and after removing duplicates, screening the titles and abstracts, and reviewing the full text, 7 studies were included. The interrater reliability was 77.73% (kappa statistic = 0.1842). Most studies estimated the proportion of women that sought for colposcopy after a previous screening test for human papilloma virus. One study identifies barriers to colposcopy examination in women at risk of developing cervical cancer. Three studies assessed the decentralization of colposcopy from a tertiary healthcare center to a primary care center. Pap smear was the most common first-line screening test, followed by liquid-based cytology sample and visual inspection with acetic acid. CONCLUSION Only a few countries have investigated the use of colposcopy in primary care. Thus, barriers and the care structure for this implementation to be successful in reducing cervical cancer incidence and mortality should be identified.

Abstract
BACKGROUND Standardized residency training is an essential aspect of enhancing the ability of cancer prevention and screening of residents. The current study was performed to investigate tumor prevention, screening literacy and the training demands of standardized training residents and explore related influencing factors. METHODS A cross-sectional survey was conducted among 320 residents of The First Hospital of Lanzhou University. An online, self-designed questionnaire was employed to investigate tumor prevention and screening, training status, and the requirements of residents. Data were analyzed using Fisher's exact test. RESULTS The mean age of the 320 participants was 26.04 ± 1.85 years;133, 83, and 104 were in the 1st, 2nd and 3rd year of standardized training, respectively. Among the common carcinogenic factors, smoking, infectious agents, and drinking were more correlated with tumors by 72.19, 66.57, and 64.38% of the physicians, respectively. Excess body weight, an insufficient intake of fruits and dietary fiber, and a lack of exercise were correlated with tumors by only 26.56, 25, and 23.44% of the physicians, respectively. The proportion of physicians providing an accurate answer to the tumor screening question ranged from 23.13 to 93.13%. The lowest accuracy was 23.13% for the initial age of regular breast cancer screening in general-risk women. The maximum rate of the primary liver cancer screening methods was 93.13%. Postgraduates and residents of oncology practitioners considered excess body weight and the insufficient intake of fruits and dietary fiber more relevant to cancer (P < 0.05). Male residents viewed more associations between tumors and a lack of exercise and air pollution (P < 0.05). Overall, 71.26% of participants felt that their tumor prevention and screening knowledge was poor and 95.31% thought they needed standardized tumor prevention and screening training. CONCLUSION Tumor prevention and screening literacy of standardized training residents should be further improved. There is a huge knowledge demand for tumor prevention and screening. Therefore, it is vital to build a training program in line with the requirements of cancer prevention and control efforts that focus on improving literacy among residents.

Abstract
Administration of the human papillomavirus (HPV) vaccine in early adolescence is effective in preventing cervical cancer, a common cancer in sub-Saharan Africa. Nigeria is in the pre-introduction era of the HPV vaccine. Understanding the preferences of the population for the vaccine can help design the HPV immunization program to ensure high uptake of the vaccine. This study explored the preferences for the HPV vaccine among stakeholders in selected communities in Ibadan, Nigeria. A discrete choice experiment survey based on six attributes of the HPV vaccine (which were the number of doses, the efficacy of the vaccine, cost of the vaccine, location of the service point, other benefits of the vaccine apart from prevention of cervical cancer and the odds of a side effect from the vaccine) was carried out in five communities. Data were analyzed using conditional and mixed logit models. Seven hundred community members were recruited, 144 (20.7%) were adolescents and 248 (35.4%) were males. In line with expectations, respondents preferred vaccines with higher efficacy, less severe side effects and lower costs. Preference heterogeneity was identified for adolescents that were less price-sensitive and other community members who were less likely to prefer using schools as the service point. The high socioeconomic class preferred a vaccine that also prevents genital warts. There were variabilities in the preferences for the attributes of the HPV vaccine in the study communities. These variabilities need to be considered in the introduction of the HPV vaccine to ensure high uptake of the vaccine.

Abstract
Erythropoietin-producing hepatoma receptor A2 (EphA2), receptor tyrosine kinase, the most widespread member of the largest receptor tyrosine kinase family, plays a critical role in physiological and pathological conditions. In recent years, the role of EphA2 in the occurrence and development of cancer has become a research hotspot and is considered a promising potential target. Our previous studies have shown that EphA2 has an indisputable cancer-promoting role in cervical cancer, but its related mechanism requires further research. In this study, high-throughput sequencing was performed on EphA2 knockdown cervical cancer cells and the control group. An analysis of differentially expressed genes revealed that EphA2 may exert its cancer-promoting effect through C-X-C motif chemokine ligand 11 (CXCL11). In addition, we found that EphA2 could further regulate programmed cell death ligand 1 (PD-L1) through CXCL11. This has also been further demonstrated in in vivo experiments. Our study demonstrated that EphA2 plays a tumor-promoting role in cervical carcinoma through the CXCL11/PD-L1 pathway, providing new guidance for the targeted therapy and combination therapy of cervical carcinoma.

Int J Clin Pract 2022; 2022:3356431. [PMID: 36263235 PMCID: PMC9546700 DOI: 10.1155/2022/3356431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Accepted: 07/29/2022] [Indexed: 11/20/2022] Open
Abstract
Background Cervical cancer, especially in underdeveloped areas, poses a great threat to human health. In view of this, we stratified the age and social demographic index (SDI) based on the epidemiological development trend and attributable risk of cervical cancer in countries and regions around the world. Methods According to the data statistics of the global burden of disease database (GBD) in the past 30 years, we adopted the annual percentage change (EAPCs) to evaluate the incidence trend of cervical cancer, that is, incidence rate, mortality, and disability adjusted life expectancy (DALY). Meanwhile, we investigated the potential influence of SDI on cervical cancer's epidemiological trends and relevant risk factors for cervical cancer-related mortality. Results In terms of incidence rate and mortality, the high SDI areas were significantly lower than those of low SDI areas. The incidence and mortality in women aged 20 to 39 were relatively stable, whereas an upward trend existed in patients aged 40 to 59. The global cervical cancer incidence rate increased from 335642 in 1990 to 565541 in 2019 (an increase of 68.50%, with an average annual growth rate of 2.28%), while the age-standardized incidence rate (ASIR) showed a slight downward trend of 14.91/100000 people (95% uncertainty interval [UI], 13.37-17.55) in 1990 to 13.35/100,000 persons (95% UI, 11.37-15.03) in 2019. The number of annual deaths at a global level increased constantly and there were 184,527 (95% UI, 164,836-218,942) deaths in 1990 and 280,479 (95% UI, 238,864-313,930) deaths in 2019, with an increase of 52.00%(average annual growth rate: 1.73%). The annual age-standardized disability adjusted annual life rate showed a downward trend (decline range: 0.95%, 95% confidence interval [CI], from -1.00% to - 0.89%). In addition, smoking and unsafe sex were the main attributable hazard factors in most GBD regions. Conclusions In the past three decades, the increase in the global burden of cervical cancer is mainly concentrated in underdeveloped regions (concentrated in low SDI). On the contrary, in countries with high sustainable development index, the burden of cervical cancer tends to be reduced. Alarmingly, ASIR in areas with low SDI is on the rise, which suggests that policy makers should pay attention to the allocation of public health resources and focus on the prevention and treatment of cervical cancer in underdeveloped areas, so as to reduce its incidence rate, mortality, and prognosis.

An Overview of HPV Screening Tests to Improve Access to Cervical Cancer Screening Amongst Underserved Populations: From Development to Implementation. Risk Manag Healthc Policy 2022; 15:1823-1830. [PMID: 36176779 PMCID: PMC9514784 DOI: 10.2147/rmhp.s296914] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Accepted: 09/14/2022] [Indexed: 12/12/2022] Open
Abstract
Cervical cancer is the most common human papillomavirus (HPV)-related disease. Knowledge of the natural history and aetiology of cervical cancer offers unique opportunities for its prevention, and the development of HPV screening tests is one of the most effective strategies. The current HPV diagnostics detect HPV DNA or E6/E7 mRNA in cervical/vaginal samples using molecular-based technologies. HPV screening tests are more sensitive than cytology or visual inspection with acetic acid (VIA) as a primary screening method and are even more clinically valuable in triaging mild cytological abnormalities as a hybrid test. As technical and laboratory resources are grossly limited in marginalized or underserved settings which thus require that women travel long distances for screening and treatment. The practical implementation of an HPV-based screening programme may face many challenges and measures should be instituted to overcome these challenges without compromising disease detection. These measures may include a reduction in screening frequency using the WHO global strategy of offering HPV screening tests at 35 and 45 years of age, adoption of a high throughput testing technology, and improved access to vaginal HPV self-sampling screening tests to women in remote settings or those who are reluctant to undergo gynecologic examination. Another important strategy is the implementation of a "see-and-treat" approach using a point-of-care platform that requires limited skills of laboratory technicians. In addition, the development and large-scale incorporation of more specific HPV testing technologies that are much cheaper and easier to use in non-laboratory settings than the currently available options should be prioritized for underserved settings. At the same time, there is a need to develop and commence the implementation of an affordable and readily available intermediate or secondary test with optimal specificity for triaging or segregating clinically unimportant HPV infections that do not require colposcopy.

Abstract
BACKGROUND Cervical cancer continues to be a major health problem in developing countries. Educational programs, as well as Pap and HPV screening and vaccination, are important tools to reduce the morbidity and mortality rates associated with this disease. The objective of this study is to explore the diverse knowledge and perceptions about cervical cancer and the different diagnostic tests for HPV of populations living in the rural parish "El Valle". METHOD A qualitative study was conducted through eight focus groups, which included 46 participants from mixed ethnic groups. A phenomenological analysis was performed. RESULTS Four topics and seven sub-topics were identified. By analyzing all the narratives, it was possible to identify that the perception of cervical cancer was focused on its severity, secondary to its infectious process and screening periodicity. However, despite the diverse knowledge, indigenous people do not relate it to the human papilloma virus; in addition, there is also certain resistance to undergo the Pap smear test, for reasons such as inaccessibility and its sampling process. CONCLUSIONS It is necessary to develop educational programs for the prevention of cervical cancer and to implement diagnostic alternatives to reach populations with precarious accessibility, as well as women who refuse to undergo the Pap smear test.

Abstract
Pachymic acid has various pharmacological effects, including anti-inflammatory, antioxidant, immunomodulatory, and antitumor. However, the role of pachymic acid in cervical cancer remains unclear. So, we investigated the effects of pachymic acid in cervical cancer and elucidated the underlying mechanisms. We treated HeLa cells and normal cervical epithelial cells (HUCECs) with pachymic acid (0, 10, 20, 40, 80, or 160 μM) for 72 h, and found the cell activity was decreased in cells treated with 160 μM pachymic acid for 48 h or 80 μM pachymic acid for 72 h, while HUCECs viability without effect. Next, we observed that endoplasmic reticulum (ER) related gene expression, mitochondrial membrane potential (MMP) changes, ATP depletion, reactive oxygen species (ROS) generation and apoptosis were increased. Moreover, we observed that cytochrome C (Cytc) expression was increased and apoptosis-inducing factor (AIF) was decreased in the cytoplasm of pachymic acid-treated HeLa cells. Tauroursodeoxycholic acid (TUDCA) of ER stress inhibitor reversed the effects of pachymic acid on HeLa cells. Phosphorylation of AMPK and acetyl-CoA carboxylase (ACC) of the AMPK pathway key protein was upregulated in pachymic acid-induced HeLa cells. Finally, we subcutaneously implanted HeLa cells into female nude mice and treated them with pachymic acid (50 mg/kg) for 3 weeks (5 days/week), and observed in pachymic acid induced xenograft mice, tumor growth was suppressed, cell apoptosis, ER-related gene expression, and ROS levels in tumor tissues were increased. Therefore, these findings demonstrated that pachymic acid plays an anti-tumor activity in cervical cancer through inducing ER stress, mitochondrial dysfunction, and activating the AMPK pathway.

Abstract
Karyopherin α (KPNA) proteins are involved in nucleocytoplasmic trafficking and are critical for protein subcellular localization. Recent studies have suggested that KPNA proteins are abnormally expressed in various solid tumors. The objective of this study was to investigate the expression of KPNA1 and KPNA2 in cervical cancer tissue with different histologic grades and cell lines, as well as the effects of the KPNA1 expression level on Hela cell proliferation. We collected the medical data of 106 patients with cervical cancer and investigated the protein expression of KPNA1 and KPNA2 by immunohistochemistry and western blot. The results revealed a significantly lower expression of KPNA1 in cervical cancer compared to normal tissue. Conversely, stronger staining intensity for KPNA2 was observed in cervical tumor samples. The expression levels of KPNA1 and KPNA2 were significantly associated with the tumor histologic grade. The weakest KPNA1 expression and strongest staining for KPNA2 were observed in grade III tumor tissue. The expression levels of KPNA1 were lower in Hela and C33A cells compared with normal human cervical epithelial cells; however, the expression of KPNA2 exhibited an opposite trend. The up-regulation of KPNA1 significantly suppressed the proliferation of Hela cells and relevant proteins expression, as well as promoted transportation of IRF3 into nucleus. Our results suggest the downregulation of KPNA1 expression is related to the malignant degree of cervical cancer and is closely associated with the proliferation of cervical cancer cells.

Abstract
Objective To explore the diagnosis of cervical intraepithelial neoplasia (CIN) and invasive cervical carcinoma (ICC) by cervical biopsy under colposcopy and analyze the factors influencing the detection. Methods The clinical data of 134 CIN confirmed by colposcopy biopsy in our hospital from June 2018 to October 2019 and subsequent LEEP treatment were analyzed retrospectively. All patients were diagnosed pathologically after the operation. The diagnosis of CIN by cervical biopsy under colposcopy was observed. The influencing factors of CIN and ICC detected by colposcopy biopsy were analyzed by the pathological results of loop electrosurgical excision procedure (LEEP) as the gold standard. Results After LEEP, the number of the no intraepithelial or malignant lesions (NILM) or ICC were higher than that of colposcopy biopsy, and CIN-III was lower than that of colposcopy biopsy, the differences were all statistically significant (P < 0.05). Among the 134 patients, the coincidence rate between colposcopy biopsy and LEEP examination results was 79.10% (106/134), and postoperative pathological findings showed that there were 13 cases (9.70%) with the pathological upgrade and 19 cases (14.18%) with pathological decrease. Multivariate logistic analysis showed that the image quality of colposcopy image, atypical blood vessels, biopsy sampling method, and visible lesion area of the cervix were the independent influencing factors for the detection of CIN and ICC by colposcopy biopsy (P < 0.05). Conclusion CIN and ICC can be diagnosed by colposcopy cervical biopsy and postoperative histopathology. However, there are still some missed and misdiagnosed cervical biopsies under colposcopy, and the combined detection of the two can further ensure the diagnosis rate. The clinical registration number is E2018091.

Abstract
Background Recently, the upregulation of LINC00963 expression has been reported in various cancer subtypes. LINC00963 expression can promote cancer cell invasion and metastasis. However, the clinical significance of LINC00963 in cervical and endocervical cancer (CESC) has remained relatively unexamined. Material/Methods We assessed the mRNA expression of LINC00963 in patients with CESC based on data acquired from The Cancer Genome Atlas (TCGA) to determine pathways involved in CESC pathogenesis with respect to LINC00963. We included 3 normal and 304 tumor samples in this study. Results The scatter plot and paired plot showed differences in LINC00963 expression between normal and tumor samples (P<0.01). Overall survival (OS) analysis revealed that CESC patients with high expression of LINC00963 demonstrated worse prognosis than CESC patients with low expression of LINC00963 (P<0.01). Multivariate analysis with the Cox proportional hazards model indicated that the expression of LINC00963 (HR 0.297; 95% CI 0.115–0.776; P=0.012) and primary therapy outcome (HR 0.162; 95% CI 0.059–0.446; P=0.001) were independent prognostic factors for patients with CESC. GSEA results showed that reactome biological oxidations, inflammasomes, apoptosis, toll-like receptor signaling pathway, JAK/STAT signaling pathway, and NF-κB activation were differentially enriched in CESC samples with the high LINC00963 expression phenotype. Conclusions Our results confirmed the association of significantly high levels of LINC00963 expression in CESC with several observed clinical features. LINC00963 may be a potentially useful prognostic molecular biomarker associated with poor survival in patients with CESC.

Abstract
Methyglyoxal (MGO), an essential endogenous dicarbonyl metabolite, can lead to multiple physiological problems including hyperglycemia, kidney diseases, malignant tumors, beyond its normal concentration range. The glyoxalase system, making MGO maintained at a low level, links glycation to carcinogenesis, growth, metastasis, and cancer chemotherapy. The glyoxalase system comprises glyoxalase 1 (Glo1) and glyoxalase 2 (Glo2), which is often overexpressed in various tumor tissues. However, very little is known about the glyoxalase system in breast cancer and gynecological cancer. In this review, we introduce the role of the glyoxalase system in breast cancer, endometrial cancer, ovarian cancer and cervical cancer, and highlight the potential of the glyoxalase system to be both as a marker for diagnosis and a novel target for antitumor therapy. However, the intrinsic molecular biology and mechanisms of the glyoxalase system in breast cancer and gynecological cancer need further exploration.

Abstract
Simple Summary For cancer patients, many different reasons can cause financial burdens and economic threads. Sociodemographic factors, rural/remote location and income are known determinants for these vulnerable groups. This economic vulnerability is related to the reduced utilization of cancer care and the impact on outcome. Financial burden has been reported in many countries throughout the world and needs to be addressed as part of the sufficient quality of cancer care. Abstract Within healthcare systems in all countries, vulnerable groups of patients can be identified and are characterized by the reduced utilization of available healthcare. Many different reasons can be attributed to this observation, summarized as implementation barriers involving acceptance, accessibility, affordability, acceptability and quality of care. For many patients, cancer care is specifically associated with the occurrence of vulnerability due to the complex disease, very different target groups and delivery situations (from prevention to palliative care) as well as cost-intensive care. Sociodemographic factors, such as educational level, rural/remote location and income, are known determinants for these vulnerable groups. However, different forms of financial burdens likely influence this vulnerability in cancer care delivery in a distinct manner. In a narrative review, these socioeconomic challenges are summarized regarding their occurrence and consequences to current cancer care. Overall, besides direct costs such as for treatment, many facets of indirect costs including survivorship costs for the cancer patients and their social environment need to be considered regarding the impact on vulnerability, treatment compliance and abundance. In addition, individual cancer-related financial burden might also affect the society due to the loss of productivity and workforce availability. Healthcare providers are requested to address this vulnerability during the treatment of cancer patients.

Abstract
Long non-coding RNAs (lncRNAs) play important roles in the occurrence and progression of tumors. Extensive research has contributed to the current understanding of the critical roles played by lncRNAs in various cancers. LncRNA MIR4435-2HG has been found to be crucial in many cancers, such as breast, cervical, colorectal, and gastric cancer. Expression of MIR4435-2HG is generally upregulated in cancers and MIR4435-2HG participates in many biological functions through molecular mechanism of competitive endogenous RNA networks. This review profiles recent research findings on the expression, functions, mechanism, and clinical value of MIR4435-2HG in cancer, and serves as a reference for further MIR4435-2HG-related research and clinical trials.

Abstract
Background DNA-methylation-based machine learning algorithms have demonstrated powerful diagnostic capabilities, and these tools are currently emerging in many fields of tumor diagnosis and patient prognosis prediction. This work aimed to identify novel DNA methylation diagnostic biomarkers for differentiating cervical cancer (CC) from normal tissues, as well as a prognostic prediction model to predict survival of CC patients. Methods The methylation profiles with the available clinical characteristics were downloaded from the Gene Expression Omnibus (GEO) database and The Cancer Genome Atlas (TCGA) program. We first screened out the differential methylation sites in CC and normal tissues and performed multiple statistical analyses to discover DNA methylation diagnostic markers that are used to distinguish CC and normal control. Then, we developed a methylation-based survival model to improve risk stratification. Results A diagnostic prediction panel consists of five CpG markers that could predict cervical cancer versus normal tissue with highly correct rate of 100%, and cg16428251, cg22341310, and cg23316360 which in diagnostic prediction panel all could yield high sensitivity and specificity for detection of CC and normal in six cohorts (area under curve [AUC] > 0.8), in addition to excellent performance in discriminating between CC and normal sample. The diagnostic marker panel also effectively predicted the CIN3 versus normal tissue with high accuracy in two datasets (AUC = 0.80, 0.789, respectively). Furthermore, a prognostic prediction model aggregated two CpG markers that effectively stratified the prognosis of high-risk and low-risk groups (training cohort: hazard ratio [HR] 4, 95% CI: 1.7–9.6, P = 0.0021; testing cohort: hazard ratio [HR] 1.9, 95% CI: 1.2–3.1, P = 0.0072). Conclusion The findings of our study showed that DNA methylation markers are of great value in the diagnosis and prognosis of CC.

Abstract
Background Cervical cancer is the fourth most frequent malignancy among women globally, with approximately 604,000 new cases and 341,000 deaths per year. Necroptosis is a newly discovered mechanism of cell death involved in biological behaviors of cancer. Methods LASSO Cox regression analysis was conducted to construct a prognostic necroptosis-related signature. lncRNA–miRNA–mRNA regulatory axis was constructed with a ceRNA network. qRT-PCR was performed to verify our result. Results A total of 54 necroptosis-related genes were differentially expressed in cervical cancer (all p < 0.05). We also summarized genetic mutation landscape of necroptosis-related genes in cervical cancer. We then developed a necroptosis-related prognostic signature including 13 necroptosis-related genes (ATRX, AXL, DDX58, IDH1, ITPK1, MAP3K7, SLC39A7, TARDBP, TNF, TNFRSF1A, TNFRSF1B, TNFSF10, TRIM11) for cervical cancer. Cervical cancer patients with high riskscore had a poor overall survival (HR = 2.128, p = 0.00194) with an AUC of 0.725, 0.763 and 0.637 in 3-year, 5-year, and 10-year ROC curve. Consensus clustering analysis revealed that all cervical cancer cohort could be divided into three subtypes, which was correlated with different prognosis and immune infiltration (p < 0.05). A PPI network revealed TNF as the hub gene and TNF expression was correlated with immune infiltration (all p < 0.05), microsatellite instability (p < 0.012) and drug sensitivity (p < 0.05). The ceRNA network was performed and identified a lncRNA NUTM2B-AS1/miR-361-5p/TNF regulatory axis for cervical cancer. qRT-PCR result also suggested that TNF was upregulated in cervical cancer (p < 0.001) and associated with a poor overall survival (p = 0.007). Univariate and multivariate analysis demonstrated TNF expression, lymph node metastasis and clinical stage were prognosis factors of cervical cancer patients (p < 0.05). Conclusion We developed a necroptosis-related prognostic signature including 13 necroptosis-related genes for cervical cancer. Moreover, we also identified a lncRNA NUTM2B-AS1/miR-361-5p/TNF regulatory axis, which may play a vital role in the progression of cervical cancer. Further studies should be conducted to verify these results.

Assessment of a Mobile Health iPhone App for Semiautomated Self-management of Chronic Recurrent Medical Conditions Using an N-of-1 Trial Framework: Feasibility Pilot Study. JMIR Form Res 2022; 6:e34827. [PMID: 35412460 PMCID: PMC9044158 DOI: 10.2196/34827] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Revised: 02/11/2022] [Accepted: 02/19/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Management of chronic recurrent medical conditions (CRMCs), such as migraine headaches, chronic pain, and anxiety/depression, remains a major challenge for modern providers. Our team has developed an edge-based, semiautomated mobile health (mHealth) technology called iMTracker that employs the N-of-1 trial approach to allow self-management of CRMCs. OBJECTIVE This study examines the patterns of adoption, identifies CRMCs that users selected for self-application, and explores barriers to use of the iMTracker app. METHODS This is a feasibility pilot study with internet-based recruitment that ran from May 15, 2019, to December 23, 2020. We recruited 180 patients to pilot test the iMTracker app for user-selected CRMCs for a 3-month period. Patients were administered surveys before and after the study. RESULTS We found reasonable usage rates: a total of 73/103 (70.9%) patients who were not lost to follow-up reported the full 3-month use of the app. Most users chose to use the iMTracker app to self-manage chronic pain (other than headaches; 80/212, 37.7%), followed by headaches in 36/212 (17.0%) and mental health (anxiety and depression) in 27/212 (12.8%). The recurrence rate of CRMCs was at least weekly in over 93% (169/180) of patients, with 36.1% (65/180) of CRMCs recurring multiple times in a day, 41.7% (75/180) daily, and 16.1% (29/180) weekly. We found that the main barriers to use were the design and technical function of the app, but that use of the app resulted in an improvement in confidence in the efficiency and safety/privacy of this approach. CONCLUSIONS The iMTracker app provides a feasible platform for the N-of-1 trial approach to self-management of CRMCs, although internet-based recruitment provided limited follow-up, suggesting that in-person evaluation may be needed. The rate of CRMC recurrence was high enough to allow the N-of-1 trial assessment for most traits.

Abstract
Malignant tumors pose a serious threat to human health and have high fatality rates. Conventional clinical anti-tumor treatment is mainly based on traditional surgery, chemotherapy, radiotherapy, and interventional therapy, and even though these treatment methods are constantly updated, a satisfactory efficacy is yet to be obtained. Therefore, research on novel cancer treatments is being actively pursued. We review the classification of gene therapies of malignant tumors and their advantages, as well as the development of gene editing techniques. We further reveal the nano-drug delivery carrier effect in improving the efficiency of gene editing. Finally, we summarize the progress in recent years of gene editing techniques based on nano-drug delivery carriers in the treatment of various malignant tumors, and analyze the prospects of the technique and its restricting factors.

Abstract
PURPOSE To explore the regulatory effect of let-7a-5p/TGFBR1/Smad3 on the proliferation activity of cervical cancer cells. METHODS The difference in let-7a-5p expression between normal people and patients with cervical cancer was detected by miREIA assay. The differences of let-7a-5p expression between cervical cancer cell line C33a and adjacent normal epithelial cell line HUCEC were determined by qRT-PCR. RESULTS miREIA result showed that let-7a-5p concentrations were 178.5 ± 24.3 μg/L in healthy individuals and 106.1 ± 14.8 μg/L in cervical cancer patients (P = 0.0002). qRT-PCR showed that let-7a-5p in cervical cancer tissue (0.57 ± 0.03) was lower than that in adjacent normal tissue (0.84 ± 0.04, P = 0.0107). Compared with normal cervical epithelial cells (HUCEC), the expression of let-7a-5p was lower in cervical cancer cells (C33a, Hela, P = 0.0001). The results of CCK-8 and EDU detection showed that activation of let-7a-5p inhibited the proliferation of C33a (P = 0.00130, P << 0.0001) and Hela (P = 0.00254, P = 0.0066) cells. According to the analysis using Starbase V2.0 online database, let-7a-5p could target TGFβR1 in cervical cancer cell lines, and the let-7a-5p mimic reduces the mRNA expression level of TGFβR1 in cervical cancer cell C33a (P = 0.0067). Western blot results showed that TGFBR1 expression significantly decreased in cervical cancer cells after let-7a-5p mimic treatment (P = 0.0048) and significantly increased after let-7a-5p mimic inhibitor treatment (P = 0.0003). CONCLUSIONS let-7a-5p represents the independent novel anti-oncogenes in cervical cancer, which can regulate TGF-β1/TGFBR1/pSmad3 cell pathway and interfere with the proliferation of cervical cancer cells. Therefore, let-7a-5p can serve as a novel potential therapeutic target for the treatment of cervical cancer.

Abstract
BACKGROUND: Cervical cancer is the second-most common cancer in Indonesian women. While the cervical cancer screening has been integrated in Indonesian primary health-care facilities, the HPV vaccination has not yet become a national program.
AIM: The objective of this research was to measure the knowledge, attitude, and behavior of medical students in Jakarta toward cervical cancer and its prevention. The result of this study could be implemented to develop a more comprehensive national educational program and public health policy.
METHODS: We conducted a cross-sectional study on medical students at 10 different universities in Jakarta, Indonesia. Student’s knowledge, attitude, and behavior were collected through a self-administered online questionnaire consist of a total of 27 questions concerning cervical cancer epidemiology, pathogenesis, screening, diagnosis, and prevention.
RESULTS: A total of 2159 medical students participated in this study. More than half (55%) of the students obtained satisfactory knowledge score. The students’ knowledge regarding HPV vaccination was low. However, 87.2% of them agreed to get the HPV vaccination. Only 7.0% had participated in cervical cancer screening program and only 16.8% had received HPV vaccination. Female gender, second or third year of study, and three universities had better odds to have good practice score.
CONCLUSION: The knowledge and attitude score did not reflect on student’s practice on cervical cancer and its prevention. Effort to increase the awareness toward cervical cancer should be endorsed through university curriculum and public health policy.

The relationship between hormonal contraception and cervical dysplasia/cancer controlling for human papillomavirus infection: A systematic review. Contraception 2022; 107:1-9. [PMID: 34752778 PMCID: PMC8837691 DOI: 10.1016/j.contraception.2021.10.018] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 10/27/2021] [Accepted: 10/28/2021] [Indexed: 11/03/2022]
Abstract
OBJECTIVE Studies on the effect of long-term use of combined oral contraceptives (COCs) on cervical dysplasia and/or cancer risk have been inconsistent. Less is known about the effects of other forms of hormonal contraception (HC). We examine whether HC use increases the risk of incident cervical intraepithelial neoplasia (CIN) 2, 3 and/or cancer after accounting for preexisting human papillomavirus (HPV) infection. STUDY DESIGN Systematic review of prospective studies on HC use as risk factor for cervical dysplasia with HPV infection documented prior to outcome assessment including PubMed and EMBASE records between January 2000 and February 2020 (Prospero #CRD42019130725). RESULTS Among nine eligible studies, seven described recency and type of HC use and therefore comprise the primary analysis; two studies limit comparisons to ever versus never use and are summarized separately. All seven studies explored the relationship between oral contraceptive (OC) use and cervical dysplasia/cancer incidence: two found increased risk (adjusted odds ratio, aOR = 1.5-2.7), one found no association but decreased risk when restricted to women with persistent HPV (adjusted hazard ratio = 0.5), and four found no association. None of the seven studies differentiated between COC and progestin-only pills (POPs) by use recency or duration. The only study that included injectable progestin-only contraception (DMPA) found increased CIN3 incidence among current versus never users (aOR = 1.6). The one study that included Norplant found no association. Two studies included intrauterine device (IUD) use, but did not differentiate between hormonal and copper IUDs, and found no association. CONCLUSION We found no consistent evidence that OC use is associated with increased risk for cervical dysplasia/cancer after controlling for HPV infection. There were too few studies of progestin-only injectables, implants or IUDs to assess their effect on cervical dysplasia/cancer risk. IMPLICATIONS Use of single self-reported HC measures and insufficient distinction by hormonal constituent cloud our understanding of whether some HCs increase risk for cervical cancer. Methodologically rigorous studies with distinct HCs measured as time-varying exposures are needed to inform cervical cancer prevention efforts and improve our understanding of cervical cancer etiology.
