Abstract
OBJECTIVE To compare the cost-effectiveness of different treatments for cervical intraepithelial neoplasia (CIN). DESIGN A cost-effectiveness analysis based on data available in the literature and expert opinion. SETTING England. POPULATION Women treated for CIN. METHODS We developed a decision-analytic model to simulate the clinical course of 1000 women who received local treatment for CIN and were followed up for 10 years after treatment. In the model we considered surgical complications as well as oncological and reproductive outcomes over the 10-year period. The costs calculated were those incurred by the National Health Service (NHS) of England. MAIN OUTCOME MEASURES Cost per one CIN2+ recurrence averted (oncological outcome); cost per one preterm birth averted (reproductive outcome); overall cost per one adverse oncological or reproductive outcome averted. RESULTS For young women of reproductive age, large loop excision of the transformation zone (LLETZ) was the most cost-effective treatment overall at all willingness-to-pay thresholds. For postmenopausal women, LLETZ remained the most cost-effective treatment up to a threshold of £31,500, but laser conisation became the most cost-effective treatment above that threshold. CONCLUSIONS LLETZ is the most cost-effective treatment for both younger and older women. However, for older women, more radical excision with laser conisation could also be considered if the NHS is willing to spend more than £31,500 to avert one CIN2+ recurrence.

Abstract
INTRODUCTION Breast cancer poses a significant health challenge in Sub-Saharan Africa, particularly in Ghana, where late-stage diagnoses and limited healthcare access contribute to elevated mortality rates. This study focuses on the crucial role of pathology and laboratory medical (PALM) services in the timely diagnosis of breast cancer within Ghana. METHODS A cross-sectional survey of hospitals was completed from November 2020 to October 2021, with 94.8% of identified in-country hospitals participating. Pathology service-related parameters assessed included whether pathology was available for the diagnosis of breast cancer on-site or via external referral, the number of pathology personnel, additional breast cancer diagnostic capabilities including estrogen and progesterone and/or HER2 testing, and the time from biopsy to patients receiving their results. Geospatial mapping was used to identify areas of limited access. RESULTS Of the 328 participating hospitals, 136 (41%) reported breast cancer pathology services, with only 6 having on-site capabilities. Pathology personnel, comprising 15 consultants and 15 specialists, were concentrated in major referral centers, particularly in Greater Accra and Kumasi. An assessment of referral patterns suggested that 75% of the population reside within an hour of breast cancer pathology services. Among the 136 hospitals with access to breast cancer pathology, only a limited number reported that results included ER/PR (38%) and HER2 testing (33%). CONCLUSION Ghana has been able to ensure significant pathology service availability through robust referral pathways with centralized labs. Despite this, difficulties persist with the majority of pathology results not including hormone receptor testing which is important in providing tumor specific treatment.

Abstract
OBJECTIVE To analyse the global burden, trends and cross-country inequalities of female breast and gynaecologic cancers (FeBGCs). DESIGN Population-Based Study. SETTING Data sourced from the Global Burden of Disease Study 2019. POPULATION Individuals diagnosed with FeBGCs. METHODS Age-standardised mortality rates (ASMRs), age-standardised Disability-Adjusted Life Years (DALYs) rates (ASDRs) and their 95% uncertainty interval (UI) described the burden. Estimated annual percentage changes (EAPCs) and their confidence interval (CI) of age-standardised rates (ASRs) illustrated trends. Social inequalities were quantified using the Slope Index of Inequality (SII) and Concentration Index. MAIN OUTCOME MEASURES The main outcome measures were the burden of FeBGCs and the trends in its inequalities over time. RESULTS In 2019, the ASDRs per 100 000 females were as follows: breast cancer: 473.83 (95% UI: 437.30-510.51), cervical cancer: 210.64 (95% UI: 177.67-234.85), ovarian cancer: 124.68 (95% UI: 109.13-138.67) and uterine cancer: 210.64 (95% UI: 177.67-234.85). The trends per year from 1990 to 2019 were expressed as EAPCs of ASDRs and these: for Breast cancer: -0.51 (95% CI: -0.57 to -0.45); Cervical cancer: -0.95 (95% CI: -0.99 to -0.89); Ovarian cancer: -0.08 (95% CI: -0.12 to -0.04); and Uterine cancer: -0.84 (95% CI: -0.93 to -0.75). In the Social Inequalities Analysis (1990-2019) the SII changed from 689.26 to 607.08 for Breast, from -226.66 to -239.92 for cervical, from 222.45 to 228.83 for ovarian and from 74.61 to 103.58 for uterine cancer. The concentration index values ranged from 0.2 to 0.4. CONCLUSIONS The burden of FeBGCs worldwide showed a downward trend from 1990 to 2019. Countries or regions with higher Socio-demographic Index (SDI) bear a higher DALYs burden of breast, ovarian and uterine cancers, while those with lower SDI bear a heavier burden of cervical cancer. These inequalities increased over time.

Am J Epidemiol 2024; 193:1182-1196. [PMID: 38400646 PMCID: PMC11299034 DOI: 10.1093/aje/kwae010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 02/01/2024] [Accepted: 02/20/2024] [Indexed: 02/25/2024] Open
Abstract
We synthesized the epidemiologic evidence on the associations between per- and polyfluoroalkyl substances (PFAS) exposure and breast cancer risk. Our systematic review and meta-analysis included 18 and 11 articles, respectively, covering studies up to February 2023. The summary relative risks (RRs) estimated by random-effects meta-analyses did not support an association between PFAS and overall breast cancer risk (eg, a natural log (ln)-unit increase in serum/plasma concentrations [ng/mL] for perfluorooctanoate [PFOA] RR = 0.95; 95% CI, 0.77-1.18; perfluorooctane sulfonate [PFOS] RR = 0.98; 95% CI, 0.87-1.11). However, when limiting to studies that assessed exposures prior to a breast cancer diagnosis, we observed a positive association with PFOA (a ln-unit increase, RR = 1.16; 95% CI, 0.96-1.40). We also observed some possible heterogeneous associations by tumor estrogen and progesterone receptor status among postmenopausal breast cancer cases. No meaningful changes were observed after excluding the studies with high risk of bias (Tier 3). Based on the evaluation tool developed by the National Toxicology Program, given the heterogeneity across studies and the variability in timing of exposure measurements, the epidemiologic evidence needed to determine the association between PFAS exposure and breast cancer remains inadequate. Our findings support the need for future studies with improved study designs to determine this association.

[PMID: 39050105 PMCID: PMC11268131 DOI: 10.1016/j.eclinm.2024.102713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 06/14/2024] [Accepted: 06/19/2024] [Indexed: 07/27/2024] Open
Abstract
Background The global status of women's health is underestimated, particularly the burden on women of child-bearing age (WCBA). We aim to investigate the pattern and trend of female cancers among WCBA from 1990 to 2021. Methods We retrieved data from the Global Burden of Disease Study (GBD) 2021 on the incidence and disability-adjusted life-years (DALYs) of four major female cancers (breast, cervical, uterine, and ovarian cancer) among WCBA (15-49 years) in 204 countries and territories from 1990 to 2021. Estimated annual percentage changes (EAPC) in the age-standardised incidence and DALY rates of female cancers, by age and socio-demographic index (SDI), were calculated to quantify the temporal trends. Spearman correlation analysis was used to examine the correlation between age-standardised rates and SDI. Findings In 2021, an estimated 1,013,475 new cases of overall female cancers were reported globally, with a significant increase in age-standardised incidence rate (EAPC 0.16%), and a decrease in age-standardised DALY rate (-0.73%) from 1990 to 2021. Annual increase trends of age-standardised incidence rate were observed in all cancers, except for that in cervical cancer. Contrary, the age-standardised DALY rate decreased in all cancers. Breast and cervical cancers were prevalent among WCBA worldwide, followed by ovarian and uterine cancers, with regional disparities in the burden of four female cancers. In addition, the age-standardised incidence rates of breast, ovarian, and uterine cancers basically showed a consistent upward trend with increasing SDI, while both the age-standardised incidence and DALY rates in cervical cancer exhibited downward trends with SDI. Age-specific rates of female cancers increased with age in 2021, with the most significant changes observed in younger age groups, except for uterine cancer. Interpretation The rising global incidence of female cancers, coupled with regional variations in DALYs, underscores the urgent need for innovative prevention and healthcare strategies to mitigate the burden among WCBA worldwide.

Abstract
Background Sexual transmission accounts for a substantial proportion of HIV infections. Although some countries are experiencing an upward trend in HIV infections, there has been a lack of studies assessing the global burden of HIV/AIDS acquired through sexual transmission. We assessed the global, regional, and national burdens of HIV/AIDS acquired through sexual transmission from 1990 to 2019. Methods Data on deaths, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALY) of HIV/AIDS acquired through sexual transmission in 204 countries and territories from 1990 to 2019 were retrieved from the Global Burden of Disease Study (GBD) 2019. The burdens and trends were evaluated using the age-standardised rates (ASR) and estimated annual percentage change (EAPC). Results Globally, HIV/AIDS acquired through sexual transmission accounted for ~695.8 thousand (95% uncertainty interval 628.0-811.3) deaths, 33.0million (28.7-39.9) YLLs, 3.4million (2.4-4.6) YLDs, and 36.4million (32.2-43.1) DALYs in 2019. In 2019, Southern sub-Saharan Africa (11350.94), Eastern sub-Saharan Africa (3530.91), and Western sub-Saharan Africa (2037.74) had the highest ASR of DALYs of HIV/AIDS acquired through sexual transmission per 100,000. In most regions of the world, the burden of HIV/AIDS acquired through sexual transmission has been increasing from 1990 to 2019, mainly in Oceania (EAPC 17.20, 95% confidence interval 12.82-21.75), South Asia (9.00, 3.94-14.30), and Eastern Europe (7.09, 6.35-7.84). Conclusions HIV/AIDS acquired through sexual transmission results in a major burden globally, regionally, and nationally.

Abstract
OBJECTIVES Women in the criminal justice system and women who have been subject to domestic abuse are at high risk of cancer but underrepresented in health promotion research. We aimed to co-produce, pilot and evaluate a health promoting programme delivered on group walks. DESIGN A programme co-produced by women, based on motivational interviewing, created the opportunity for supportive conversations about cancer prevention. METHODS Programme development in two workshops with women with lived experience using authentic vignettes to prompt help-seeking conversations. A small pilot and a qualitative evaluation was done using framework analysis. RESULTS The programme appeared acceptable to women and the walk leaders. Women felt included and found it a safe space for sensitive conversations. They appeared empowered and more confident to seek help. Walk leaders expressed confidence in delivering this informal programme, which used prompts rather than delivering didactic training. CONCLUSION Cancer prevention for high-risk groups can be delivered in a personalised and novel way by creating informal opportunities for supportive conversations about cancer prevention. Careful co-production of the programme of walks with women, using scenarios and quotes that were authentic vignettes, ensured that these came directly from the women's lived experience and enabled women to talk about change. Our findings indicate that this approach was practical, relevant and acceptable to them with some evidence of women feeling empowered to make informed decisions about their health. We recommend that future cancer prevention programmes for underrepresented groups take an asset-based approach by utilising pre-existing community organisations to increase reach and sustainability. PATIENT AND PUBLIC INVOLVEMENT Women with lived experience co-designed and tested the programme. Provisional findings were fed back to the women and the women's organisation that partnered with this research.

Abstract
BACKGROUND The two major causes of cancer-related deaths among women in Ghana are breast cancer (BC) and cervical cancer (CC). These types of cancers typically do not show any symptoms until they have progressed. Therefore, it is important to screen for early detection. This research aimed to investigate the rate of breast cancer and cervical cancer screening, as well as the factors associated with it, among women of reproductive age in Ghana. METHODS This study analysed data from the 2022 Ghana Demographic and Health Survey. A total of 15,014 women aged 15 to 49 years were included in the analysis. Descriptive statistics and binary logistic regression were employed to analyse the data with the aid of STATA/SE, version 17. RESULTS It was found that 18.4% and 5.0% of the women had screened for BC and CC, respectively. Women aged 45-49 years were about three times more likely (aOR = 2.83, 95% CI: 1.88-4.24) to screen for BC compared to those aged 15-19 years. Women who had tested for HIV had increased odds (aOR = 1.88, 95% CI: 1.56-2.25) of screening for BC compared to their counterparts. Women within the richest wealth index (aOR = 1.95, 95% CI: 1.40-2.72) had increased odds of screening for BC compared to those in the poorest wealth index. Regarding CC screening, women with higher education (aOR = 2.56, 95% CI: 1.53-4.29) were two times more likely to screen for CC compared to those with no formal education. Women who did not use tobacco (aOR = 0.45, 95% CI: 0.21-0.96) had decreased odds of CC screening compared to their counterparts. CONCLUSIONS This study showed that the uptake of BC and CC screening services among women in Ghana was very low. The drivers of BC and CC screening included enabling, predisposing, and need factors. Stakeholders can leverage the mass media to raise awareness and educate women in reproductive age about the importance of BC and CC screening. This study provides relevant information that can inform BC and CC policies and programmes in Ghana.

Abstract
Numerous studies over the past few decades have shown that RNAs are multifaceted, multifunctional regulators of most cellular processes, contrary to the initial belief that they only act as mediators for translating DNA into proteins. LncRNAs, which refer to transcripts longer than 200nt and lack the ability to code for proteins, have recently been identified as central regulators of a variety of biochemical and cellular processes, particularly cancer. When they are abnormally expressed, they are closely associated with tumor occurrence, metastasis, and tumor staging. Therefore, through searches on Google Scholar, PubMed, and CNKI, we identified five five recently characterized lncRNAs-Lnc-SLC2A12-10:1, LncRNA BCRT1, lncRNA IGFBP4-1, LncRNA PCNAP1, and LncRNA CDC6-that have been linked to the promotion of cancer cell proliferation, invasion, and metastasis. Consequently, this review encapsulates the existing research and molecular underpinnings of these five newly identified lncRNAs across various types of cancer. It suggests that these novel lncRNAs hold potential as independent biomarkers for clinical diagnosis and prognosis, as well as candidates for therapeutic intervention. In parallel, we discuss the challenges inherent in the research on these five newly discovered lncRNAs and look forward to the avenues for future exploration in this field.

Abstract
The self-renewal and differentiation properties of cancer stem cells (CSCs) result in chemoresistance in breast cancer. Even though numerous drugs have been developed to target CSCs, they have suffered from inefficient delivery and accumulation at the focal site. Here, a thermoresponsive hydrogel is developed by coencapsulating aggregation-induced emission (AIE)-active photothermal agent and thioridazine (THZ), demonstrating a controllable delivery system triggered by the AIE agent to augment THZ-mediated CSC ablation. Upon near-infrared laser stimuli, the photothermal effect from the AIE agent induces hydrogel deformation for burst drug release. The precise in situ tumor administration of the hydrogel accelerates drug diffusion and accumulation in deep breast cancer lesions. Thus, THZ can invade tumors and provoke massive CSC apoptosis via dopamine receptor blockage and oxidative stress induction. Consequently, effective CSC inhibition and significant suppression of tumor recurrence and metastasis are demonstrated in mice with breast cancer. We believe that this intelligent hydrogel-based delivery system represents a promising treatment strategy for metastatic breast cancer with clinical potential.

Abstract
OBJECTIVE To estimate the catastrophic health expenditure and distress financing of breast cancer treatment in India. METHODS The unit data from a longitudinal survey that followed 500 breast cancer patients treated at Tata Memorial Centre (TMC), Mumbai from June 2019 to March 2022 were used. The catastrophic health expenditure (CHE) was estimated using households' capacity to pay and distress financing as selling assets or borrowing loans to meet cost of treatment. Bivariate and logistic regression models were used for analysis. FINDINGS The CHE of breast cancer was estimated at 84.2% (95% CI: 80.8,87.9%) and distress financing at 72.4% (95% CI: 67.8,76.6%). Higher prevalence of CHE and distress financing was found among rural, poor, agriculture dependent households and among patients from outside of Maharashtra. About 75% of breast cancer patients had some form of reimbursement but it reduced the incidence of catastrophic health expenditure by only 14%. Nearly 80% of the patients utilised multiple financing sources to meet the cost of treatment. The significant predictors of distress financing were catastrophic health expenditure, type of patient, educational attainment, main income source, health insurance, and state of residence. CONCLUSION In India, the CHE and distress financing of breast cancer treatment is very high. Most of the patients who had CHE were more likely to incur distress financing. Inclusion of direct non-medical cost such as accommodation, food and travel of patients and accompanying person in the ambit of reimbursement of breast cancer treatment can reduce the CHE. We suggest that city specific cancer care centre need to be strengthened under the aegis of PM-JAY to cater quality cancer care in their own states of residence.

Abstract
Gynaecological cancers originate within the female reproductive system and are classified according to the site in the reproductive system where they arise. However, over 50 % of these malignancies are categorized as rare, encompassing 30 distinct histological subtypes, which complicates their diagnosis and treatment. The focus of this review is to give an overview of established in vitro models for the investigation of rare gynaecological cancers, as well as an overview of available online databases that contain detailed descriptions of cell line characteristics. Cell lines represent the main models for the research of carcinogenesis, drug resistance, pharmacodynamics and novel therapy treatment options. Nowadays, classic 2D cell models are increasingly being replaced with 3D cell models, such as spheroids, organoids, and tumoroids because they provide a more accurate representation of numerous tumour characteristics, and their response to therapy differs from the response of adherent cell lines. It is crucial to use the correct cell line model, as rare tumour types can show characteristics that differ from the most common tumour types and can therefore respond unexpectedly to classic treatment. Additionally, some cell lines have been misclassified or misidentified, which could lead to false results. Even though rare gynaecological cancers are rare, this review will demonstrate that there are available options for investigation of such cancers in vitro on biologically relevant models.

Abstract
The prospect of drinking water serving as a conduit for gut bacteria, artificially selected by disinfection strategies and a lack of monitoring at the point of use, is concerning. Certain opportunistic pathogens, notably some nontuberculous mycobacteria (NTM), often exceed coliform bacteria levels in drinking water, posing safety risks. NTM and other microbiota resist chlorination and thrive in plumbing systems. When inhaled, opportunistic NTM can infect the lungs of immunocompromised or chronically ill patients and the elderly, primarily postmenopausal women. When ingested with drinking water, NTM often survive stomach acidity, reach the intestines, and migrate to other organs using immune cells as vehicles, potentially colonizing tumor tissue, including in breast cancer. The link between the microbiome and cancer is not new, yet the recognition of intratumoral microbiomes is a recent development. Breast cancer risk rises with age, and NTM infections have emerged as a concern among breast cancer patients. In addition to studies hinting at a potential association between chronic NTM infections and lung cancer, NTM have also been detected in breast tumors at levels higher than normal adjacent tissue. Evaluating the risks of continued ingestion of contaminated drinking water is paramount, especially given the ability of various bacteria to migrate from the gut to breast tissue via entero-mammary pathways. This underscores a pressing need to revise water safety monitoring guidelines and delve into hormonal factors, including addressing the disproportionate impact of NTM infections and breast cancer on women and examining the potential health risks posed by the cryptic and unchecked microbiota from drinking water.

Cost-effectiveness of approaches to cervical cancer screening in Malawi: comparison of frequencies, lesion treatment techniques, and risk-stratified approaches. BMC Health Serv Res 2024; 24:792. [PMID: 38982430 PMCID: PMC11234730 DOI: 10.1186/s12913-024-11226-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Accepted: 06/20/2024] [Indexed: 07/11/2024] Open
Abstract
BACKGROUND Recently-updated global guidelines for cervical cancer screening incorporated new technologies-most significantly, the inclusion of HPV DNA detection as a primary screening test-but leave many implementation decisions at countries' discretion. We sought to develop recommendations for Malawi as a test case since it has the second-highest cervical cancer burden globally and high HIV prevalence. We incorporated updated epidemiologic data, the full range of ablation methods recommended, and a more nuanced representation of how HIV status intersects with cervical cancer risk and exposure to screening to model outcomes of different approaches to screening. METHODS Using a Markov model, we estimate the relative health outcomes and costs of different approaches to cervical cancer screening among Malawian women. The model was parameterized using published data, and focused on comparing "triage" approaches-i.e., lesion treatment (cryotherapy or thermocoagulation) at differing frequencies and varying by HIV status. Health outcomes were quality-adjusted life years (QALYs) and deaths averted. The model was built using TreeAge Pro software. RESULTS Thermocoagulation was more cost-effective than cryotherapy at all screening frequencies. Screening women once per decade would avert substantially more deaths than screening only once per lifetime, at relatively little additional cost. Moreover, at this frequency, it would be advisable to ensure that all women who screen positive receive treatment (rather than investing in further increases in screening frequency): for a similar gain in QALYs, it would cost more than four times as much to implement once-per-5 years screening with only 50% of women treated versus once-per-decade screening with 100% of women treated. Stratified screening schedules by HIV status was found to be an optimal approach. CONCLUSIONS These results add new evidence about cost-effective approaches to cervical cancer screening in low-income countries. At relatively infrequent screening intervals, if resources are limited, it would be more cost-effective to invest in scaling up thermocoagulation for treatment before increasing the recommended screening frequency. In Malawi or countries in a similar stage of the HIV epidemic, a stratified approach that prioritizes more frequent screening for women living with HIV may be more cost-effective than population-wide recommendations that are HIV status neutral.

Abstract
Background: Breast cancer is the second most common cause of cancer-related mortality globally. Apolipoprotein L3 (APOL3), a member of the apolipoprotein family, has been implicated in the pathogenesis of cardiovascular diseases. Nevertheless, the functions and underlying mechanisms of APOL3 in breast cancer have yet to be elucidated. Methods: The patient data were sourced from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database. Quantitative real-time PCR (qRT-PCR), western blotting, and immunohistochemistry (IHC) assays were used to assess expression of APOL3. Cell proliferation rates were determined by Cell Counting Kit-8 (CCK-8) and colony formation assays. Flow cytometry was used to examine cell cycle distribution. Western blotting was conducted to investigate the expression of cell cycle related proteins. A xenograft model was used to evaluate the effect of APOL3 in vivo. APOL3-binding proteins were identified through mass spectrometry, co-immunoprecipitation (CO-IP) assay and immunofluorescence assay. Results: APOL3 expression was significantly downregulated in breast cancer, and its low expression was correlated with poor prognostic outcomes. Overexpression of APOL3 suppressed breast cancer cell proliferation, induced cell cycle disruption. Conversely, knockdown of APOL3 promoted cell proliferation. In vivo animal experiments demonstrated that APOL3 overexpression can inhibit tumor proliferation. Mass spectrometry, CO-IP and immunofluorescence assay confirmed the interaction between APOL3 and Y-box binding protein 1 (YBX1). Furthermore, YBX1 knockdown following APOL3 knockdown mitigated the enhanced proliferation. These results provide new ideas for clinically targeting APOL3 to inhibit proliferation in breast cancer. Conclusions: Our findings indicate that APOL3 inhibits breast cancer cell proliferation and cell cycle modulating P53 pathway through the interaction of YBX1.

Abstract
Background: Long non-coding RNA (lncRNA), a crucial regulator in breast cancer (BC) development, is intricately linked with cellular senescence. However, there is a lack of cellular senescence-related lncRNAs (CSRLs) signature to evaluate the prognosis of BC patients. Methods: Correlation analysis was conducted to identify lncRNAs associated with cellular senescence. Subsequently, a CSRL signature was crafted in the training cohort. The model's accuracy was evaluated through survival analysis and receiver operating characteristic curves. Furthermore, prognostic nomograms amalgamating cellular senescence and clinical characteristics were devised. Tumor microenvironment and checkpoint disparities were compared between low-risk and high-risk groups. The correlation between these signatures and treatment response in BC patients was also investigated. Finally, functional experiments were conducted for validation. Results: A signature comprising nine CSRLs was devised, which demonstrated adept prognostic capability in BC patients. Functional enrichment analysis revealed that tumor and immune-related pathways were predominantly enriched. Compared to the low-risk group, the high-risk group could benefit more from immunotherapy and certain chemotherapeutic agents. The expression of the 9 CSRLs was validated through in vitro experiments in different subtypes of BC cell lines and tissues. AC098484.1 was specifically verified for its association with senescence-associated secretory phenotypes. Conclusion: The CSRLs signature emerges as a promising prognostic biomarker for BC, with implications for immunological studies and treatment strategies. AC098484.1 has potential relevance in the treatment of BC cell senescence, and these findings improve the clinical treatment levels for BC patients.

Abstract
Diagnoses of breast cancer are continuing to increase in the Philippines, but little is known about incidence rates among the significant number of Filipino women working abroad as migrant domestic workers (MDWs). These women are often the main income providers for their families, and their ability to work depends upon their physical health and strength. In this article, we use interpretive phenomenological analysis to explore the experiences of 10 MDWs from the Philippines who were diagnosed with breast cancer during a period of employment in Hong Kong. Analysis of these narratives revealed numerous points at which their status as temporary, transnational migrant workers intersected with their experiences of breast cancer detection, diagnosis, and treatment. We argue that these women's experiences of breast cancer were shaped by the structures of migration that link the Philippines with host destinations like Hong Kong. These structures create a unique context in which these women had to constantly renegotiate their identities as migrants, financial providers, and breast cancer patients.

[PMID: 37726429 PMCID: PMC11192698 DOI: 10.1007/s10198-023-01627-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 08/16/2023] [Indexed: 09/21/2023]
Abstract
BACKGROUND This study aimed to conduct a systematic review of the cost-effectiveness studies of interventions to increase cervical cancer screening uptake rates in underserved women in Europe. METHODS A search of Embase, Medline, Global Health, PsychINFO, and NHS Economic Evaluation Database was conducted for studies published between January 2000 and September 2022. Studies were eligible if they analysed the cost-effectiveness of any interventions to improve participation in cervical cancer screening among underserved women of any age eligible to participate in cervical cancer screening in European countries, in any language. Study characteristics and cost-effectiveness results were summarised. Study quality was assessed using the Drummond Checklist, and methodological choices were further compared. RESULTS The searches yielded 962 unique studies, with 17 of these (from twelve European countries) meeting the eligibility criteria for data extraction. All studies focused on underscreened women as an overarching group, with no identified studies focusing on specific subgroups of underserved women. Generally, self-HPV testing and reminder interventions were shown to be cost-effective to increase the uptake rates. There was also research showing that addressing access issues and adopting different screening modalities could be economically attractive in some settings, but the current evidence is insufficient due to the limited number of studies. CONCLUSION This systematic review has revealed a gap in the literature on the cost-effectiveness of interventions to improve uptake rates of cervical cancer screening through tailored provision for specific groups of underserved women.

Abstract
OBJECTIVE Adherence to combinatorial treatments are important predictors of improved long-term outcomes for patients with glioblastoma (GB); however, factors associated with refusal of surgery, chemotherapy, or radiotherapy (RT) by patients with GB have not been studied. METHODS The National Cancer Database was queried from 2004 to 2018 to identify patients with a primary diagnosis of GB who underwent surgical resection alone or followed by either RT or chemotherapy. Adult patients who voluntarily rejected a physician's recommendations for 1 or more treatment were selected. Multivariable regression was used to identify factors associated with rejection of surgical resection, chemotherapy, and RT. Patients receiving treatment were 3:1 propensity score matched to those rejecting treatment and median overall survival (OS) was compared. RESULTS 58,788 patients were included in the analysis. Factors associated with voluntary refusal of GB treatment included: old age, nonprivate insurance, female sex, Black race, comorbidities, treatment at a nonacademic facility, and living 55+ miles away from a treatment facility (P < 0.05). On propensity matched analysis, refusal of surgery conferred a 4 month decrease in OS (P < 0.001), RT an 8 month decrease in OS (P < 0.001), and chemotherapy a 7 month decrease in OS (P < 0.001). CONCLUSIONS In patients with GB, age, sex, race, nonprivate insurance, medical comorbidities, distance from treatment facility, and geographic location were associated with refusal of surgery, postsurgical RT, and chemotherapy. In addition, treatment refusal had a significant impact on OS length.

Abstract
INTRODUCTION Psycho-oncological support (POS) and psychopharmacological interventions are effective in treating psychiatric symptoms in patients with breast cancer. However, despite high prevalences of psychiatric disorders in patients with breast cancer, a significant proportion remains untreated. METHODS Data from 1062 breast cancer patients who had been diagnosed and treated at a Comprehensive Cancer Center between 2012 and 2019 were analyzed retrospectively. We descriptively evaluated the number of patients with a psychiatric diagnosis, POS and psychiatric medication. Latent class analysis was used to examine the relationship between ICD-10 coded psychiatric diagnoses, POS, psychiatric medication, and, as important prognostic factors, tumor stage and somatic comorbidity. RESULTS 31.5% of all patients had a psychiatric diagnosis, 20% received POS and up to 60% received psychiatric medication. Latent class analysis revealed three subgroups: 1) patients with a low cancer stage, low somatic comorbidity, no psychiatric diagnosis, no POS and no psychiatric medication; 2) patients with a low cancer stage, low somatic comorbidity, a psychiatric diagnosis, and a higher probability of POS and psychiatric medication than class 1 and class 3; 3) patients with advanced cancer stage, high somatic comorbidity, a higher probability of a psychiatric diagnosis and POS than class 1, and no psychiatric medication. CONCLUSION This study indicated a high prevalence of psychiatric disorders among patients with breast cancer and a discrepancy between the number of patients having a psychiatric disorder and those receiving psychiatric medication. The identification of subgroups might contribute to better tailored treatment for those patients whose needs are insufficiently met.

Abstract
As cancer continues to rise globally, there is growing interest in discovering novel methods for prevention and treatment. Due to the limitations of traditional cancer therapies, there has been a growing emphasis on investigating herbal remedies and exploring their potential synergistic effects when combined with chemotherapy drugs. Cinnamaldehyde, derived from cinnamon, has gained significant attention for its potential role in cancer prevention and treatment. Extensive research has demonstrated that cinnamaldehyde exhibits promising anticancer properties by modulating various cellular processes involved in tumor growth and progression. However, challenges and unanswered questions remain regarding the precise mechanisms for its effective use as an anticancer agent. This article aims to explore the multifaceted effects of cinnamaldehyde on cancer cells and shed light on these existing issues. Cinnamaldehyde has diverse anti-cancer mechanisms, including inducing apoptosis by activating caspases and damaging mitochondrial function, inhibiting tumor angiogenesis, anti-proliferation, anti-inflammatory and antioxidant. In addition, cinnamaldehyde also acts as a reactive oxygen species scavenger, reducing oxidative stress and preventing DNA damage and genomic instability. This article emphasizes the promising therapeutic potential of cinnamaldehyde in cancer treatment and underscores the need for future research to unlock novel mechanisms and strategies for combating cancer. By providing valuable insights into the role and mechanism of cinnamaldehyde in cancer, this comprehensive understanding paves the way for its potential as a novel therapeutic agent. Overall, cinnamaldehyde holds great promise as an anticancer agent, and its comprehensive exploration in this article highlights its potential as a valuable addition to cancer treatment options.

Abstract
PURPOSE Breast cancer (BC) is a devastating disease for women. Microbial influences may be involved in the development and progression of breast cancer. This study aimed to investigate the difference in intestinal flora abundance between breast cancer patients and healthy controls (HC) based on previous 16S ribosomal RNA (rRNA) gene sequencing results, which have been scattered and inconsistent in previous studies. MATERIALS AND METHODS In agreement with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), we searched for pertinent literature in Pubmed, Embase, Cochrane Library, and Web of Science databases from build until February 1, 2023. Relative abundance, diversity of intestinal microflora by level, microbial composition, community structure, diversity index, and other related data were extracted. We used a fixed or random effects model for data analysis. We also conducted funnel plot analysis, sensitivity analysis, Egger's, and Begg's tests to assess the bias risk. RESULTS A total of ten studies involving 734 BC patients were enrolled. It was pointed out that there were significant differences in the Chao index between BC and HC in these studies [SMD = - 175.44 (95% CI - 246.50 to - 104.39)]. The relative abundance of Prevotellaceae [SMD = - 0.27 (95% CI - 0.39 to - 0.15)] and Bacteroides [SMD = 0.36 (95% CI 0.23-0.49)] was significantly different. In the included articles, the relative abundance of Prevotellaceae, Ruminococcus, Roseburia inulinivorans, and Faecalibacterium prausnitzii decreased in BC. Accordingly, the relative richness of Erysipelotrichaceae was high in BC. CONCLUSIONS This observational meta-analysis revealed that the changes in gut microbiota were correlated with BC, and the changes in some primary fecal microbiota might affect the beginning of breast cancer.

Abstract
PURPOSE Follow-up guidelines barely diverge from a one-size-fits-all approach, even though the risk of recurrence differs per patient. However, the personalization of breast cancer care improves outcomes for patients. This study explores the variation in follow-up pathways in the Netherlands using real-world data to determine guideline adherence and the gap between daily practice and risk-based surveillance, to demonstrate the benefits of personalized risk-based surveillance compared with usual care. METHODS Patients with stage I-III invasive breast cancer who received surgical treatment in a general hospital between 2005 and 2020 were selected from the Netherlands Cancer Registry and included all imaging activities during follow-up from hospital-based electronic health records. Process analysis techniques were used to map patients and activities to investigate the real-world utilisation of resources and identify the opportunities for improvement. The INFLUENCE 2.0 nomogram was used for risk prediction of recurrence. RESULTS In the period between 2005 and 2020, 3478 patients were included with a mean follow-up of 4.9 years. In the first 12 months following treatment, patients visited the hospital between 1 and 5 times (mean 1.3, IQR 1-1) and received between 1 and 9 imaging activities (mean 1.7, IQR 1-2). Mammogram was the prevailing imaging modality, accounting for 70% of imaging activities. Patients with a low predicted risk of recurrence visited the hospital more often. CONCLUSIONS Deviations from the guideline were not in line with the risk of recurrence and revealed a large gap, indicating that it is hard for clinicians to accurately estimate this risk and therefore objective risk predictions could bridge this gap.

Abstract
BACKGROUND The aim of this study was to investigate the knowledge, awareness, and attitude of mothers of preadolescent girls regarding the HPV vaccination and cervical cancer, and to understand how to improve the efficacy of the Italian vaccination campaign through the gathered data. METHODS A questionnaire-based survey was conducted in mothers of unvaccinated 9 to 12-year-old girls in Italy from November 2018 to July 2019, to evaluate their awareness and the attitude toward HPV, its vaccination, and the information sources of the vaccination campaign. The selection of the distribution sites of the questionnaire was performed with randomization of 50 major places of aggregation located throughout the Italian territory. RESULTS Three hundred mothers of unvaccinated girls were included in the study and divided into two groups (191 subjects <45 years old, 109 subjects >45 years old). Results showed that 79.6% of <45 years old knew what HPV is, compared to 60.6% of >45 years old (P value <0.001); only 60.2% (<45 years old) and 54.1% (>45 years old) showed awareness about the HPV vaccine (P value 0.03). The percentage of parents against vaccination in preadolescent was higher in the >45 years old (29.4%); however, most of them appeared favorable to the information campaigns regarding the vaccine (P value <0.001). CONCLUSIONS Our study showed that mothers of unvaccinated preadolescent girls have suboptimal knowledge on the topic. Moreover, the implementation of communication strategies dedicated to the population segment appears as a central aspect. As HPV vaccination keeps being a public health concern, it is fundamental to understand which trigger should be managed by healthcare decision makers to boost the vaccination campaigns.

Abstract
PURPOSE Female breast cancer (BC) is the leading cause of cancer incidence and mortality in India, and accounted for 13.5% of new cancer cases and 10% of cancer-related deaths in 2020. This study aims to estimate and report the female BC burden in India at state level from 2012 to 2016 in terms of years of life lost, years lived with disability, and disability-adjusted life years (DALYs), and to project the burden for the year 2025. METHODS The cancer incidence and mortality data from 28 population-based cancer registries were analysed. The mean mortality to incidence ratio was estimated, and mortality figures were adjusted for underreporting. The burden of female BC was estimated at national and subnational levels using Census data, World Health Organisation's lifetables, disability weights, and the DisMod-II tool. A negative binomial regression is employed to project burden for 2025. RESULTS The burden of BC among Indian women in 2016 was estimated to be 515.4 DALYs per 100,000 women after age standardization. The burden metrics at state level exhibited substantial heterogeneity. Notably, Tamil Nadu, Telangana, Karnataka, and Delhi had a higher burden of BC than states in the eastern and north-eastern regions. The projection for 2025 indicates to a substantial increase, reaching 5.6 million DALYs. CONCLUSION The female BC burden in India was significantly high in 2016 and is expected to substantially increase. Undertaking a multidisciplinary, context-specific approach for its prevention and control can address this rising burden.

Abstract
The ubiquitin-proteasome system (UPS) is an essential regulatory system for maintaining homeostasis, and its dysfunction may cause various diseases. The activity of proteasome and ubiquitin-conjugating enzymes has been found to be greatly increased in breast cancer (BC), indicating that the heterogeneity of UPS may be related to the progression of BC. Gene data was obtained from The Cancer Genome Atlas and Gene Expression Omnibus databases and performed in multiple algorithms to construct a UPS-related signature for BC. Patients in the UPS low-risk group had greater overall and recurrence-free survival probability than those in the UPS high-risk group. This signature was closely associated with functional enrichment. Some high metabolism-related pathways were more active in the UPS high-risk group. The UPS low-risk group had more abundant anti-tumor immune cells, while in the UPS high-risk group, immunosuppressive cells were dominant. More importantly, we found that the UPS low-risk group was more sensitive to immunotherapy, while the UPS high-risk group responded better to radiotherapy. Drug sensitivity analysis identified more effective chemotherapy drugs in different UPS-related risk groups. This UPS-related signature may serve as a novel biomarker and independent prognostic factor for BC. It can effectively predict prognosis, immune infiltration, and therapy efficacy, providing new strategies for individualized treatment.

COMPUTER METHODS AND PROGRAMS IN BIOMEDICINE 2024; 250:108194. [PMID: 38678959 DOI: 10.1016/j.cmpb.2024.108194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 04/13/2024] [Accepted: 04/21/2024] [Indexed: 05/01/2024]
Abstract
BACKGROUND AND OBJECTIVE Accurate identification of molecular biomarker statuses is crucial in cancer diagnosis, treatment, and prognosis. Studies have demonstrated that medical images could be utilized for non-invasive prediction of biomarker statues. The biomarker status-associated features extracted from medical images are essential in developing medical image-based non-invasive prediction models. Contrast-enhanced mammography (CEM) is a promising imaging technique for breast cancer diagnosis. This study aims to develop a neural network-based method to extract biomarker-related image features from CEM images and evaluate the potential of CEM in non-invasive biomarker status prediction. METHODS An end-to-end learning convolutional neural network with the whole breast images as inputs was proposed to extract CEM features for biomarker status prediction in breast cancer. The network focused on lesion regions and flexibly extracted image features from lesion and peri‑tumor regions by employing supervised learning with a smooth L1-based consistency constraint. An image-level weakly supervised segmentation network based on Vision Transformer with cross attention to contrast images of breasts with lesions against the contralateral breast images was developed for automatic lesion segmentation. Finally, prediction models were developed following further selection of significant features and the implementation of random forest-based classification. Results were reported using the area under the curve (AUC), accuracy, sensitivity, and specificity. RESULTS A dataset from 1203 breast cancer patients was utilized to develop and evaluate the proposed method. Compared to the method without lesion attention and with only lesion regions as inputs, the proposed method performed better at biomarker status prediction. Specifically, it achieved an AUC of 0.71 (95 % confidence interval [CI]: 0.65, 0.77) for Ki-67 and 0.73 (95 % CI: 0.65, 0.80) for human epidermal growth factor receptor 2 (HER2). CONCLUSIONS A lesion attention-guided neural network was proposed in this work to extract CEM image features for biomarker status prediction in breast cancer. The promising results demonstrated the potential of CEM in non-invasively predicting the biomarker statuses in breast cancer.

Abstract
BACKGROUND This study aims to assess the long-term trends in the burden of three major gynecologic cancers(GCs) stratified by social-demographic status across the world from 1990 to 2019. To assess the trends of risk factor attributed mortality, and to examine the specific effects of age, period, cohort behind them in different regions. METHODS We extracted data on the mortality, disability-adjusted life years(DALYs), and age-standardized rates(ASRs) of cervical cancer(CC), uterine cancer(UC), and ovarian cancer(OC) related to risks from 1990 to 2019, as GCs burden measures. Age-period-cohort analysis was used to analyze trends in attributable mortality rates. RESULTS The number of deaths and DALYs for CC, UC and OC increased since 1990 worldwide, while the ASDRs decreased. Regionally, the ASDR of CC was the highest in low SDI region at 15.05(11.92, 18.46) per 100,000 in 2019, while the ASDRs of UC and OC were highest in high SDI region at 2.52(2.32,2.64), and 5.67(5.16,6.09). The risk of CC death caused by unsafe sex increased with age and then gradually stabilized, with regional differences. The period effect of CC death attributed to smoking showed a downward trend. The cohort effect of UC death attributed to high BMI decreased in each region, especially in the early period in middle, low-middle and low SDI areas. CONCLUSIONS Global secular trends of attributed mortality for the three GCs and their age, period, and cohort effects may reflect the diagnosis and treatment progress, rapid socioeconomic transitions, concomitant changes in lifestyle and behavioral patterns in different developing regions. Prevention and controllable measures should be carried out according to the epidemic status in different countries, raising awareness of risk factors to reduce future burden.

Abstract
The gender perspective is important for a better diagnosis and treatment of diseases, especially in the field of oncology. This study aimed to analyse the gender approach in scientific articles in the field of oncology by studying the gender composition of the authorship of papers and the gender inclusion in the research carried out. A bibliographic search of articles and reviews signed by at least one Spanish institution published between 2010 and 2019 was carried out using the Science Citation Index Expanded database in the Oncology category. A total of 7523 studies were classified according to the gender composition determined by the author's name and a randomised sample was used to evaluate the inclusion of gender perspectives using a checklist. This study revealed a lack of gender parity in the authorship of oncology publications involving Spanish participation. Papers without author gender parity were eight times higher than papers with parity and showed a greater presence of male than female authorship (58 % versus 31 %). Regarding the introduction of the gender perspective, a negative response of 68 % referring to compliance with the entire checklist was obtained, and only a fifth of the articles presented gender balance in the study sample. Moreover, there is a positive correlation between gender parity in authorship and gender perspective integration in published research. In conclusion, there is a great need to advance the inclusion of gender perspectives in cancer research to overcome gender bias and promote better prevention, detection, and intervention for cancer.

Abstract
Cervical cancer is a major health concern worldwide, highlighting the urgent need for better early detection methods to improve outcomes for patients. In this study, we present a novel digital pathology classification approach that combines Low-Rank Adaptation (LoRA) with the Vision Transformer (ViT) model. This method is aimed at making cervix type classification more efficient through a deep learning classifier that does not require as much data. The key innovation is the use of LoRA, which allows for the effective training of the model with smaller datasets, making the most of the ability of ViT to represent visual information. This approach performs better than traditional Convolutional Neural Network (CNN) models, including Residual Networks (ResNets), especially when it comes to performance and the ability to generalize in situations where data are limited. Through thorough experiments and analysis on various dataset sizes, we found that our more streamlined classifier is highly accurate in spotting various cervical anomalies across several cases. This work advances the development of sophisticated computer-aided diagnostic systems, facilitating more rapid and accurate detection of cervical cancer, thereby significantly enhancing patient care outcomes.

Abstract
BACKGROUND An increase in cancer stem cell (CSC) populations and their resistance to common treatments could be a result of c-Myc dysregulations in certain cancer cells. In the current study, we investigated anticancer effects of c-Myc decoy ODNs loaded-poly (methacrylic acid-co-diallyl dimethyl ammonium chloride) (PMA-DDA)-coated silica nanoparticles as carriers on cancer-like stem cells (NTERA-2). METHODS AND RESULTS The physicochemical characteristics of the synthesized nanocomposites (SiO2@PMA-DDA-DEC) were analyzed using FT-IR, DLS, and SEM techniques. UV-Vis spectrophotometer was applied to analyze the release pattern of decoy ODNs from the nanocomposite. Furthermore, uptake, cell viability, apoptosis, and cell cycle assays were used to investigate the anticancer effects of nanocomposites loaded with c-Myc decoy ODNs on NTERA-2 cancer cells. The results of physicochemical analytics demonstrated that SiO2@PMA-DDA-DEC nanocomposites were successfully synthesized. The prepared nanocomposites were taken up by NTERA-2 cells with high efficiency, and could effectively inhibit cell growth and increase apoptosis rate in the treated cells compared to the control group. Moreover, SiO2@PMA-DDA nanocomposites loaded with c-Myc decoy ODNs induced cell cycle arrest at the G0/G1 phase in the treated cells. CONCLUSIONS The conclusion drawn from this study is that c-Myc decoy ODN-loaded SiO2@PMA-DDA nanocomposites can effectively inhibit cell growth and induce apoptosis in NTERA-2 cancer cells. Moreover, given that a metal core is incorporated into this synthetic nanocomposite, it could potentially be used in conjunction with irradiation as part of a decoy-radiotherapy combinational therapy in future investigations.

Abstract
Background: Artificial intelligence (AI) algorithms can be applied in breast cancer risk prediction and prevention by using patient history, scans, imaging information, and analysis of specific genes for cancer classification to reduce overdiagnosis and overtreatment. This scoping review aimed to identify the barriers encountered in applying innovative AI techniques and models in developing breast cancer risk prediction scores and promoting screening behaviors among adult females. Findings may inform and guide future global recommendations for AI application in breast cancer prevention and care for female populations. Methods: The PRISMA-SCR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) was used as a reference checklist throughout this study. The Arksey and O'Malley methodology was used as a framework to guide this review. The framework methodology consisted of five steps: (1) Identify research questions; (2) Search for relevant studies; (3) Selection of studies relevant to the research questions; (4) Chart the data; (5) Collate, summarize, and report the results. Results: In the field of breast cancer risk detection and prevention, the following AI techniques and models have been applied: Machine and Deep Learning Model (ML-DL model) (n = 1), Academic Algorithms (n = 2), Breast Cancer Surveillance Consortium (BCSC), Clinical 5-Year Risk Prediction Model (n = 2), deep-learning computer vision AI algorithms (n = 2), AI-based thermal imaging solution (Thermalytix) (n = 1), RealRisks (n = 2), Breast Cancer Risk NAVIgation (n = 1), MammoRisk (ML-Based Tool) (n = 1), Various MLModels (n = 1), and various machine/deep learning, decision aids, and commercial algorithms (n = 7). In the 11 included studies, a total of 39 barriers to AI applications in breast cancer risk prediction and screening efforts were identified. The most common barriers in the application of innovative AI tools for breast cancer prediction and improved screening rates included lack of external validity and limited generalizability (n = 6), as AI was used in studies with either a small sample size or datasets with missing data. Many studies (n = 5) also encountered selection bias due to exclusion of certain populations based on characteristics such as race/ethnicity, family history, or past medical history. Several recommendations for future research should be considered. AI models need to include a broader spectrum and more complete predictive variables for risk assessment. Investigating long-term outcomes with improved follow-up periods is critical to assess the impacts of AI on clinical decisions beyond just the immediate outcomes. Utilizing AI to improve communication strategies at both a local and organizational level can assist in informed decision-making and compliance, especially in populations with limited literacy levels. Conclusions: The use of AI in patient education and as an adjunctive tool for providers is still early in its incorporation, and future research should explore the implementation of AI-driven resources to enhance understanding and decision-making regarding breast cancer screening, especially in vulnerable populations with limited literacy.

Abstract
Breastfeeding has emerged as a critical factor in understanding and potentially mitigating the risk of breast cancer among women. This review delves into the intricate relationship between breastfeeding and breast cancer, elucidating the biological mechanisms, protective effects, and broader implications for public health. Epidemiological evidence consistently demonstrates a correlation between breastfeeding and a reduced risk of breast cancer, with longer durations of lactation showing a dose-dependent decrease in risk. The biological nexus between breastfeeding and breast cancer involves hormonal changes and the elimination of potentially damaged cells, influencing breast tissue and potentially mitigating carcinogenesis. Moreover, breastfeeding appears to impact tumor subtypes and aggressiveness, particularly demonstrating associations with lower risks of hormone receptor-negative and certain aggressive breast cancer subtypes. Recognizing the significance of breastfeeding in reducing breast cancer risk has profound public health implications, necessitating comprehensive support, education, and policies to encourage and facilitate breastfeeding.

METHODS A total of 120 plasma samples from 40 patients with HER2 + BrCa were prospectively collected at three treatment times of neoadjuvant therapy (NAT) with TCbHP regimen. Serum metabolites were analyzed based on LC-MS and GC-MS data. Random forest was used to establish predictive models based on pre-therapeutic differentially expressed metabolites. Time series analysis was used to obtain potential monitors for treatment response. Transcriptome analysis was performed in nine available pre‑therapeutic specimens of core needle biopsies. Integrated analyses of metabolomics and transcriptomics were also performed in these nine patients. qRT-PCR was used to detect altered genes in trastuzumab-sensitive and trastuzumab-resistant cell lines. RESULTS Twenty-one patients achieved pCR, and 19 patients achieved non-pCR. There were significant differences in plasma metabolic profiles before and during treatment. A total of 100 differential metabolites were identified between pCR patients and non-pCR patients at baseline; these metabolites were markedly enriched in 40 metabolic pathways. The area under the curve (AUC) values for discriminating the pCR and non-PCR groups from the NAT of the single potential metabolite [sophorose, N-(2-acetamido) iminodiacetic acid, taurine and 6-hydroxy-2-aminohexanoic acid] or combined panel of these metabolites were greater than 0.910. Eighteen metabolites exhibited potential for monitoring efficacy. Several validated genes might be associated with trastuzumab resistance. Thirty-nine altered pathways were found to be abnormally expressed at both the transcriptional and metabolic levels. CONCLUSION Serum-metabolomics could be used as a powerful tool for exploring informative biomarkers for predicting or monitoring treatment efficacy. Metabolomics integrated with transcriptomics analysis could assist in obtaining new insights into biochemical pathophysiology and might facilitate the development of new treatment targets for insensitive patients.

Abstract
Improved strategies of cancer prevention and control have resulted in tangible benefits for patients with cancer. Disparities in outcome have been reported as a result of inequal access to health care. Historically, differences in health outcomes at population level have been reported according to key characteristics, including race, ethnicity and, more recently, ancestry. These population descriptors have been used to display the differences in the outcome and highlight actionable areas of health disparities, through policy and population health interventions. Yet, they have been commonly mis-intended as ultimate determinants of health outcomes, as recapitulating intrinsic biological differences. A plethora of past literature has described "biological" differences in patients belonging to a specific racial, ethnical or ancestral group, with certain cancers - commonly overlooking the social and economic contextures. The attention has ultimately focused on the existence of intrinsic differences and biological reasons, as opposed to social and economic determinants of disparities in the outcome in disadvantaged or excluded communities, thus nurturing double stigma. In our editorial, we evaluate some key roots of racial attitudes in displaying patient outcomes in oncology epidemiological studies, and call to report ultimate determinants of health - that are, primarily social and economic determinants.

Abstract
Addressing the urgent need to prevent breast cancer postoperative recurrence and brain metastasis, Fe-metal organic framework (MOF)-coated hollow mesoporous organosilica nanoparticles (HMON) with tumor microenvironment dual-responsive degradability were prepared to encapsulate doxorubicin (DOX), formulating a tissue-adhesive nanosuspension for perioperative topical medication. This nanosuspension can not only retain the sustainably released drug in the postoperative residual tumor sites but also enhance the intracellular oxidative stress of tumors for remarkable tumor ferroptosis. Interestingly, the nanosuspension can act as an immune amplifier, which could not only stimulate DC cells to secrete chemokines for T cell recruitment but also elevate antigen exposure to facilitate the antigen presentation in lymph nodes. Thus, this nanosuspension could significantly activate antitumor immune responses in both in situ tumors and metastatic encephaloma for enhanced immunotherapy. In conjunction with the clinical PD-1 antibody, the locally administered nanosuspension could achieve an advanced therapeutic outcome for inhibiting postoperative recurrence and metastasis.

Abstract
Globally, 9 million women are diagnosed with cancer each year. Breast cancer is the most commonly diagnosed cancer worldwide, followed by colorectal cancer in high-income countries and cervical cancer in low-income countries. Survival from cancer is improving and more women are experiencing long-term effects of cancer treatment, such as premature ovarian insufficiency or early menopause. Managing menopausal symptoms after cancer can be challenging, and more severe than at natural menopause. Menopausal symptoms can extend beyond hot flushes and night sweats (vasomotor symptoms). Treatment-induced symptoms might include sexual dysfunction and impairment of sleep, mood, and quality of life. In the long term, premature ovarian insufficiency might increase the risk of chronic conditions such as osteoporosis and cardiovascular disease. Diagnosing menopause after cancer can be challenging as menopausal symptoms can overlap with other common symptoms in patients with cancer, such as fatigue and sexual dysfunction. Menopausal hormone therapy is an effective treatment for vasomotor symptoms and seems to be safe for many patients with cancer. When hormone therapy is contraindicated or avoided, emerging evidence supports the efficacy of non-pharmacological and non-hormonal treatments, although most evidence is based on women older than 50 years with breast cancer. Vaginal oestrogen seems safe for most patients with genitourinary symptoms, but there are few non-hormonal options. Many patients have inadequate centralised care for managing menopausal symptoms after cancer treatment, and more information is needed about cost-effective and patient-focused models of care for this growing population.

Abstract
INTRODUCTION Although cervical cancer screening is one of the most effective strategies to reduce the incidence and mortality of cervical cancer, the percentage of cervical cancer screening in low- and middle-income counties is low. In Kenya, the current nationwide prevalence and associated factors for the detection of cervical cancer is unknown. Therefore, this study aimed to assess the prevalence and associated factors for the detection of cervical cancer screening among women of reproductive age in Kenya using the Kenyan Demographic and Health Survey 2022. METHODS This study used the most recent Kenyan Demographic and Health Survey data (2022) with a total weighted sample of 16,901 women. A mixed effects logistic regression analysis was performed and in the multivariable analysis, variables with a p-value below 0.05 were considered statistically significant. The strength of the association was evaluated using adjusted odds ratios along with their corresponding 95% confidence intervals. RESULTS The prevalence of cervical cancer screening in Kenya was 16.81%(95% CI: 16.24, 17.38%). Having a history of abortion (AOR = 1.33, 95% CI: 1.171.50, 1.43), using modern contraceptive methods (AOR = 1.57, 95% CI: 1.25, 1.95), media exposure (AOR = 1.31, 95%CI: 1.03, 1.65), primary education (AOR = 1.56, 95%CI: 1.09, 2.22), secondary education (AOR = 21.99, 95% CI: 1.1.38, 2.87), higher education (AOR = 2..50, 95% CI: 1.71, 3.65), visiting health facility within the past 12 months (AOR = 1.61, 95%CI: 1.46, 1.79), positive HIV status (AOR: 3.50, 95% CI: 2.69, 4.57), being from a community with a higher proportion of educated individuals (AOR = 1.37, 95%CI: 1.13, 1.65) and being from a community with high proportion of poor individuals (AOR = 0.72, 9 5%CI: 0.60-0.87)) were significantly associated with cervical cancer screening. CONCLUSION In Kenya, the prevalence of cervical cancer screening was found to be low. A history of abortion, use of modern contraceptives, exposure to the media, visits to health facilities in the past 12 months, HIV status, level of education, community educational level, and community wealth were identified as significant associated factors for cervical cancer screening. Therefore, it is recommended to implement targeted public health interventions that focus on these identified factors to improve the adoption of cervical cancer screening in Kenya.

Abstract
ABSTRACT This study aimed to evaluate the clinical value of automated breast volume scanner (ABVS) compared with hand-held ultrasound (HHUS). From January 2015 to May 2019, a total of 912 breast lesions in 725 consecutive patients were included in this study. κ statistics were calculated to identify interobserver agreement of ABVS and HHUS. The diagnostic performance for ABVS and HHUS was expressed as the area under the receiver operating characteristic curve, as well as the corresponding 95% confidence interval, sensitivity, and specificity. The sensitivities of ABVS and HHUS were 95.95% and 93.69%, and the specificities were 85.47% and 81.20%, respectively. A difference that nearly reached statistical significance was observed in sensitivities between ABVS and HHUS (P = 0.0525). The specificity of ABVS was significantly higher than that of HHUS (P = 0.006). When lesions were classified according to their maximum diameter, the sensitivity and specificity of ABVS were significantly higher than HHUS for lesions ≤20 mm, while they made no statistical significance between ABVS and HHUS for lesions >20 mm. The interobserver agreement for ABVS was better than that of HHUS. Automated breast volume scanner was more valuable than HHUS in diagnosing breast cancer, especially for lesions ≤20 mm, and it could be a valuable diagnostic tool for breast cancer.

Abstract
Many treatments against breast cancer decrease the level of estrogen in blood, resulting in bone loss, osteoporosis and fragility fractures in breast cancer patients. This retrospective study aimed to evaluate a novel opportunistic screening for cancer treatment-induced bone loss (CTIBL) in breast cancer patients using CT radiomics. Between 2011 and 2021, a total of 412 female breast cancer patients who received treatment and were followed up in our institution, had post-treatment dual-energy X-ray absorptiometry (DXA) examination of the lumbar vertebrae and had post-treatment chest CT scan that encompassed the L1 vertebra, were included in this study. Results indicated that the T-score of L1 vertebra had a strongly positive correlation with the average T-score of L1-L4 vertebrae derived from DXA (r = 0.91, p < 0.05). On multivariable analysis, four clinical variables (age, body weight, menopause status, aromatase inhibitor exposure duration) and three radiomic features extracted from the region of interest of L1 vertebra (original_firstorder_RootMeanSquared, wavelet.HH_glcm_InverseVariance, and wavelet.LL_glcm_MCC) were selected for building predictive models of L1 T-score and bone health. The predictive model combining clinical and radiomic features showed the greatest adjusted R2 value (0.557), sensitivity (83.6%), specificity (74.2%) and total accuracy (79.4%) compared to models that relied solely on clinical data, radiomic features, or Hounsfield units. In conclusion, the clinical-radiomic predictive model may be used as an opportunistic screening tool for early identification of breast cancer survivors at high risk of CTIBL based on non-contrast CT images of the L1 vertebra, thereby facilitating early intervention for osteoporosis.

Abstract
In this study, an attempt was made to estimate the aggregated proportion of Pap smear test uptake among women in Iran from 2012 to 2022 using meta-analysis. The data collection process involved reviewing records registered in databases between January 1, 2012, and September 11, 2022. The final data was analyzed using random effects models, and potential heterogeneity was assessed using the I2 index. To examine publication bias, Egger's test and Funnel Plot were employed. Sensitivity analysis, specifically single study exclusion Meta-analysis, was conducted to assess the influence of each individual study on the aggregated percentage of Pap smear test uptake. A total of 28,754 women were included across the 33 articles analyzed. The pooled percentage of Pap smear test uptake for both one-time and regular screenings was found to be 46.52% (95% CI: 40.91 to 52.14) and 17.80% (95% CI: 12.42 to 23.18), respectively. No significant evidence of publication bias was detected, although the influence of smaller studies was confirmed. Sensitivity analysis indicated that the overall rate of Pap smear test uptake was not highly sensitive to the results of individual studies. The findings emphasize the low rate of regular Pap smear testing among Iranian women and suggest that tailored interventions considering cultural and geographical factors specific to different provinces in Iran could help increase the utilization of this screening service.

Abstract
PURPOSE The PARCER trial provided level I evidence for image-guided intensity-modulated radiation therapy (IG-IMRT) in patients with cervical cancer. Further information regarding long-term financial impact is imperative for adoption into the National Cancer Grid of India cervical cancer resource-stratified guidelines. METHODS Patient data from the PARCER trial were analyzed to evaluate the cost implications of transitioning to IG-IMRT. Lacking differences in outcomes between the three-dimensional conformal radiation (3D-CRT) and IG-IMRT, differences in treatment costs, adverse event incidence, and toxicity management costs were examined. The overall financial impact was estimated by adding the treatment costs, toxicity management, and wage loss. This was extrapolated nationally to determine if a transition to IG-IMRT would be feasible for the Indian health care system. RESULTS Of the 300 patients in the PARCER trial, 93 faced grades ≥2 adverse events (3D-CRT = 59, IG-IMRT = 34). Patients in the 3D-CRT and IG-IMRT arms spent an average of 2.39 years and 1.96 years in toxicity, respectively. The average toxicity management and the yearly financial impact per patient were, respectively, 1.50 and 1.44 times higher for 3D-CRT patients compared with IG-IMRT patients. Extrapolation to the national level showed that treatment with 3D-CRT led to a 2.88 times higher cost ratio when compared with treatment with IG-IMRT. CONCLUSION Although the initial costs of IG-IMRT are high, on the basis of longitudinal data, it is financially inefficient to treat with 3D-CRT. Resource-stratified guidelines should include longitudinal health intervention costs rather than solely initial costs for policy decisions to implement advanced radiation technology.

Abstract
BACKGROUND Cervical cancer is the second-leading cause of death among all cancers in Ethiopia. Ethiopia plans to eliminate cervical cancer as a public health problem by 2030, following the World Health Organization's call for action. A scoping review was conducted on the status of the cervical cancer continuum towards elimination in Ethiopia. METHODS We searched articles in PubMed, Scopus, and Google Scholar. All studies conducted on cervical cancer in Ethiopia, from first date of publication to March 15, 2023, type of article, or language of publication, were included. However, conference abstracts, commentaries, and letters to the editors were excluded. We used EndNote X9 software to merge articles from different databases and automatically remove duplicates. Screening of titles, abstracts, and full texts was performed independently by two co-authors. The cancer care continuum was employed as a framework to guide data synthesis and present the findings. RESULTS Of the 569 retrieved articles, 159 were included in the review. They found that most of the articles focused on knowledge, attitude, and practice. However, there were few studies on health-seeking behavior, perception and acceptability of cervical cancer services, as well as the availability and readiness of a screening program. The review identified inadequate knowledge, attitude, and perception about cervical cancer, and highlighted that screening for cervical cancer is not widely utilized in Ethiopia. Knowledge, attitude, education status, and income were repeatedly reported as precursors influencing cervical cancer screening. Most studies concluded that there is a high prevalence of precancerous lesions and cervical cancer, as well as high mortality rates or short survival times. The review also identified significant heterogeneity in findings across time and geographic settings within each component of the cancer care continuum. CONCLUSIONS Overall, there is inadequate knowledge, perception, health-seeking behavior, screening, and treatment services, indicating that the country is falling behind its targets in eliminating cervical cancer, despite the availability of effective interventions and tools. We argue that implementation research is necessary to identify implementation issues, challenges, and strategies to scale up both primary and secondary prevention services. By doing so, Ethiopia can address cervical cancer as a public health problem and work towards its elimination.

Malapati SH, Hyland CJ, Liang G, Edelen MO, Fazzalari A, Kaur MN, Bain PA, Mody GN, Pusic AL. Use of patient-reported outcome measures after breast reconstruction in low- and middle-income countries: a scoping review. J Patient Rep Outcomes 2024; 8:25. [PMID: 38416222 PMCID: PMC10899941 DOI: 10.1186/s41687-024-00687-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 01/17/2024] [Indexed: 02/29/2024] Open
Abstract
BACKGROUND Patient-reported outcome measures (PROMs) are increasingly administered in high-income countries to monitor health-related quality of life of breast cancer patients undergoing breast reconstruction. Although low- and middle-income countries (LMICs) face a disproportionate burden of breast cancer, little is known about the use of PROMs in LMICs. This scoping review aims to examine the use of PROMs after post-mastectomy breast reconstruction among patients with breast cancer in LMICs. METHODS MEDLINE, Embase, Web of Science, CINAHL, and PsycINFO were searched in August 2022 for English-language studies using PROMs after breast reconstruction among patients with breast cancer in LMICs. Study screening and data extraction were completed. Data were analyzed descriptively. RESULTS The search produced 1024 unique studies, 33 of which met inclusion criteria. Most were observational (48.5%) or retrospective (33.3%) studies. Studies were conducted in only 10 LMICs, with 60.5% in China and Brazil and none in low-income countries. Most were conducted in urban settings (84.8%) and outpatient clinics (57.6%), with 63.6% incorporating breast-specific PROMs and 33.3% including breast reconstruction-specific PROMs. Less than half (45.5%) used PROMs explicitly validated for their populations of interest. Only 21.2% reported PROM response rates, ranging from 43.1 to 96.9%. Barriers and facilitators of PROM use were infrequently noted. CONCLUSIONS Despite the importance of PROM collection and use in providing patient-centered care, it continues to be limited in middle-income countries and is not evident in low-income countries after breast reconstruction. Further research is necessary to determine effective methods to address the challenges of PROM use in LMICs.

Shimels T, Gashawbeza B, Gedif Fenta T. Access to advanced healthcare services and its associated factors among patients with cervical cancer in Addis Ababa, Ethiopia. Front Oncol 2024; 14:1342236. [PMID: 38463222 PMCID: PMC10921226 DOI: 10.3389/fonc.2024.1342236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Accepted: 02/01/2024] [Indexed: 03/12/2024] Open
Abstract
Objective This study aimed to assess the extent of access to healthcare services, perception and associated factors among patients with cervical cancer in Addis Ababa, Ethiopia. Methods A facility-based cross-sectional study was conducted from 01 July through 30 August 2023 at two tertiary hospitals. Cases with histopathologic and clinical confirmation of cervical cancer were enrolled using a consecutive sampling technique. Data was collected through a validated questionnaire administered by interviewers using the KoboCollect application. Subsequently, the collected data underwent analysis using Statistical Sciences for Social Sciences (SPSS) version 26.0. Bivariable and multivariable regression models were performed at p ≤ 0.2 and p<0.05 statistical significance, respectively. Results A total of 391 patients were enrolled in the study. Health facilities were accessible for obtaining general medical services (56.5%), drugs (57.3%), laboratory diagnosis services (57.0%), imaging diagnosis services (56.8%), and radiotherapy services (55.8%) of the patients. Cost of services was affordable only in 11.5% of the cases. Essential anticancer medicines were out of stock for 229 (58.6%) of the patients during the past three months. About two-thirds of the patients have a good perception of access to healthcare services. In multivariable binary logistic regression, admission to the inpatient (AOR: 0.20, 95% CI: 0.06-0.67), joblessness (AOR: 0.19, 95% CI: 0.08-0.46), lower level of income to the extreme poverty line (3567ETB)(64.9 USD) (AOR: 0.19, 95% CI: 0.10-0.35), no CBHI coverage (AOR: 4.16, 95% CI: 1.76-9.85), having social support (AOR: 3.80; 95% CI: 1.96-7.41), and poor dietary practice (AOR: 2.36, 95% CI: 1.28-4.35) were found to have a statistically significant association with perceived good access to healthcare services. Conclusion Only close to a half of the patients with cervical cancer, in Addis Ababa, have adequate access to healthcare services. Nearly two-thirds of the patients reported perceived good access to the services. Many factors were found to show a statistically significant association with patients' perceived access to healthcare services.

Abstract
Goal: Cervical cancer is one of the most common cancers in women worldwide, ranking among the top four. Unfortunately, it is also the fourth leading cause of cancer-related deaths among women, particularly in developing countries where incidence and mortality rates are higher compared to developed nations. Colposcopy can aid in the early detection of cervical lesions, but its effectiveness is limited in areas with limited medical resources and a lack of specialized physicians. Consequently, many cases are diagnosed at later stages, putting patients at significant risk. Methods: This paper proposes an automated colposcopic image analysis framework to address these challenges. The framework aims to reduce the labor costs associated with cervical precancer screening in undeserved regions and assist doctors in diagnosing patients. The core of the framework is the MFEM-CIN hybrid model, which combines Convolutional Neural Networks (CNN) and Transformer to aggregate the correlation between local and global features. This combined analysis of local and global information is scientifically useful in clinical diagnosis. In the model, MSFE and MSFF are utilized to extract and fuse multi-scale semantics. This preserves important shallow feature information and allows it to interact with the deep feature, enriching the semantics to some extent. Conclusions: The experimental results demonstrate an accuracy rate of 89.2% in identifying cervical intraepithelial neoplasia while maintaining a lightweight model. This performance exceeds the average accuracy achieved by professional physicians, indicating promising potential for practical application. Utilizing automated colposcopic image analysis and the MFEM-CIN model, this research offers a practical solution to reduce the burden on healthcare providers and improve the efficiency and accuracy of cervical cancer diagnosis in resource-constrained areas.

Abstract
OBJECTIVE Relate gender inequalities with the probability of mortality from non-communicable diseases (NCD), in the countries of the world from the year 2000 to 2019, to detect the progress of Target 3.4 of the Sustainable Development Goal 3, to reduce NCD by one third between the ages of 30 and 70 by 2030. METHOD Exploratory ecological study on the association between the probability of death from NCD and the gender inequality index (GII) at the global level in 2000, 2015 and 2019. Logistic regression estimation of the risk of not being on track to meet Target 3.4 by 2019 by gender inequality. RESULTS The mean probability of death from NCD decreased progressively in all countries. Median 2000/2015/2019: women 20.20/16.58/16; men 26.59/22.45/21.88; total 23.14/20.10/19.23. The risk of not achieving the goal in 2019 is greater in countries with a lower GII than in countries with a higher GII (OR: 2.13; 95% CI: 1.14-3.99; p=0.018), being the higher risk in women (OR: 2.64; 95% CI: 1.40-5.06; p=0.003) than in men (OR: 2.12; 95% CI: 1.44-3.98; p=0.017). CONCLUSIONS The risk of deaths from NCD has decreased in both sexes in all countries of the world since the year 2000; but progress is slow, so the greater gender inequality in the countries, there is a greater risk of not achieving the reduction needed to comply with the agreement to reduce mortality from NCD by one third in 2030; this risk being greater in women than in men.
