Background: Biomarkers have revolutionized the management of colorectal cancer (CRC), facilitating early detection, prevention, personalized treatment, and minimal residual disease (MRD) monitoring. This review explores current CRC screening strategies and emerging biomarker applications., Main Body: We summarize the landscape of non-invasive CRC screening and MRD detection strategies, discuss the limitations of the current approaches, and highlight the promising potential of novel biomarker solutions. The fecal immunochemical test remained the cornerstone of CRC screening, but its sensitivity has been improved by assays that combined its performance with other stool analytes. However, their sensitivity for advanced adenomas and the patient compliance both remain suboptimal. Blood-based tests promise to increase compliance but require further refinement to compete with stool-based biomarker tests. The ideal scenario involves leveraging blood tests to increase screening participation, and simultaneously promote stool- and endoscopy-based screening among those who are compliant. Once solely reliant on upfront surgery followed by stage and pathology-driven adjuvant chemotherapy, the treatment of stage II and III colon cancer has undergone a revolutionary transformation with the advent of MRD testing after surgery. A decade ago, the concept of using a post-surgical test instead of stage and pathology to determine the need for adjuvant chemotherapy was disruptive. Today, a blood test may be more informative of the need for chemotherapy than the stage at diagnosis., Conclusion: Biomarker research is not just improving, but bringing a transformative change to CRC clinical management. Early detection is not just getting better, but improving thanks to a multi-modality approach, and personalized treatment plans are not just becoming a reality, but a promising future with MRD testing., Competing Interests: Declarations Ethics approval and consent to participate Not applicable.

Background: Colonoscopy as a common screening practice to prevent colorectal cancer lacks strong evidence. NordICC, the first randomized trial of colonoscopy screening, reported no clear clinical benefit for colonoscopy in the intention-to-screen population with suggested benefit in the risk of colorectal incidence and cancer-specific mortality in the per-protocol analyses. However, although the study was designed to perform survival analysis, no survival outcomes were reported since the underlying assumption for hazard ratio was not valid. We aimed to assess whether colonoscopy screening is associated with improved survival outcomes compared with usual care., Methods: We reconstructed patient-level data from the Kaplan-Meier estimator of the primary endpoints reported in NordICC for the intention-to-screen and adjusted per-protocol populations. The restricted-mean survival time difference (RMST-D) and restricted-mean time loss ratio (RMTL-R), which are robust alternatives to the hazard ratio without specific model assumptions, were calculated for colorectal cancer incidence and death., Results: In this study, no significant difference in colorectal cancer incidence over 10 years was found in the intention-to-screen population (RMST-D: -0.68 days, 95% CI -3.9-2.6; RMTL-R: 1.04, 95% CI 0.88-1.22) or in the per-protocol analysis population (RMST-D: -2.9 days, 95% CI -6.5-0.67; RMTL-R: 1.15, 95% CI 0.97-1.35). In the intention-to-screen population, inviting individuals to colonoscopy did not improve colorectal-cancer death (RMST-D: -0.29 days, 95% CI -1.6-1.0; RMTL-R: 1.07, 95% CI 0.78-1.48). Over 10 years, in the per-protocol analysis, individuals who underwent colonoscopy survived an average of 1.1 more days free of colorectal cancer, but this difference was not statistically significant (RMST-D: 95% CI -0.13-2.3; RMTL-R: 0.72, 95% CI 0.49-1.07)., Conclusions: In this reanalysis of the NordICC data, no evidence of improvement in survival outcomes for participants invited to undergo colonoscopy compared to usual care was identified, even when assuming that all invited participants did undergo colonoscopy. Thus, our results do not support the use of colonoscopy as a population-wide screening test as a mean to decrease colorectal cancer incidence or death., Registry: Not applicable., Competing Interests: Declarations Ethics approval and consent to participate Not applicable.

Background: The aim of this quality improvement (QI) project was to increase Colorectal Cancer (CRC) screening in patients ages 50-75 years from a baseline of 27-40% within 12 months in a primary care clinic in limited resource communities., Methods: The multidisciplinary QI-team applied the Plan-Do-Study-Act method and developed stakeholder analysis, an Ishikawa fish bone diagram, a process flow map, and a driver diagram. Major barriers to suboptimal CRC screening included limited health literacy, language preferences, absence of stool test options, and knowledge gaps among patients and providers. The outcome measure was CRC screening rates, while stool test and colonoscopy completion rates served as process measures. Major interventions included the use of a patient-navigator, leveraging digital health technology to create a novel CRC screening data dashboard, educating patients and providers, patient centered-shared decision making, and creating messages and educational videos in patient's preferred languages. We used monthly run charts and statistical process control charts (SPC) for data analysis., Results: We observed a sustainable, steady increase in CRC screening rates from baseline rates of 27.0-40.0% (n = 1304/3271) during the study period and 45.6% (n = 1493/3,271) six months post-study, with median rates of 34.0% in the run chart and mean rates of 43.0% in the SPC chart. Furthermore, we observed an increase in colonoscopy completion rates during the study and six months post-study to 65.0% (n = 411/631) and 72.9% (n = 461/631) respectively, from a baseline rate of 25.0%, with a median of 63.0% in the monthly run chart., Conclusion: The increase in CRC screening rates highlights the effectiveness of addressing barriers such as health literacy, language preferences, and knowledge gaps. This underscores the value of a multifaceted approach and the role of a patient navigator in enhancing preventive, patient-centered care. This project focused on population health and addressing social determinants of health to overcome disparities and improve CRC screening in a primary care setting. Continued emphasis on these strategies is likely to further advance colorectal cancer screening efforts., Competing Interests: Declarations Ethics approval and consent to participate This study was reviewed by the University at Buffalo human subject institutional review board and was classified as exempt from human subjects.

Background: Atypical squamous cells of undetermined significance (ASC-US) often present diagnostic challenges with cytology-based results, leading to potential underdiagnosis or overdiagnosis. An effective triage method is essential for managing these cases to reduce unnecessary referrals and treatment., Methods: A total of 322 women diagnosed with ASC-US were tested for HPV-DNA and the PAX1 and JAM3 methylation (PAX1 m /JAM3 m ) test in the study., Results: Methylation levels of PAX1 and JAM3 were significantly elevated in cervical lesions classified as CIN2 or more severe lesions (CIN2+). The methylation assay demonstrated a sensitivity of 83.8% and a specificity of 95.8%, outperforming HPV-DNA testing in differentiating high-grade cervical lesions among women with ASC-US. Moreover, PAX1 m /JAM3 m testing significantly reduced the colposcopy referral rate for further diagnostic procedures in high-risk HPV-positive women by 79.5%., Conclusions: PAX1 m /JAM3 m testing shows promise as a reliable supplemental method to HPV-DNA testing for the triage of women with cytologic ASC-US. In addition, the molecular triage based on the CISCER assay or single PAX1 or JAM3 methylation, had better effects in the women with non-HPV16/18 group. This approach could potentially minimize overtreatment and unnecessary referrals in clinical practice, enhancing patient management and resource utilization., Competing Interests: Declarations Ethical approval The name of the Approval Committee or the Internal Review Board (IRB).

Background: The World Health Organization has set ambitious goals to eliminate cervical cancer, necessitating evidence on increasing coverage and access to screening and treatment in high-burden areas. We implemented a pilot program to assess the feasibility of obtaining self-collected specimens for high-risk human papillomavirus (hr-HPV) testing in Nzulezo stilt village, a hard-to-reach community in Ghana, and inviting only hr-HPV-positive women to a central location for colposcopy and possible treatment. Subsequently, this study aimed to investigate the prevalence of hr-HPV infection and cervical lesions among the women and to explore factors potentially associated with hr-HPV infection among them., Methods: This pilot community-based cross-sectional study utilized data from screening sessions held from 2 to 20 November 2021 with specimens collected by participants using Evalyn brushes. HPV DNA testing was performed using the Sansure MA-6000 platform, while visual inspection utilized the Enhanced Visual Assessment (EVA) mobile colposcope. Univariate and multivariable nominal logistic regression was employed to explore factors associated with hr-HPV positivity., Results: Among 100 women screened (mean age, 43.6 ± 14.5 years), the overall hr-HPV prevalence rate was 39.0% (95% CI, 29.4-49.3). The prevalence rates of hr-HPV genotypes were stratified as follows: HPV16-8.0% (95% CI, 3.5-15.2), HPV18-5.0% (95% CI, 1.6-11.2), and other genotype(s) - 31.0% (95% CI, 22.1-41.0). Single-genotype infections with HPV16 and HPV18 were found in 4.0% (95% CI, 1.1-9.9) and 3.0% (95% CI, 0.6-8.5) of women, respectively. Mixed infections were observed in 1.0% (95% CI, 0.0-5.4) for HPV16 + 18, 3.0% (95% CI, 0.6-8.5) for HPV16 + other type(s), and 1.0% (95% CI, 0.0-5.4) for HPV18 + other type(s). The prevalence of cervical lesions among hr-HPV-positive women screened via colposcopy was 11.4% (95% CI, 3.2-26.7). In the multivariable model, reliance on other sources for medical bill payment was associated with hr-HPV infection (aOR, 0.20; 95% CI, 0.04-0.93), whereas age was not (aOR, 1.02; 95% CI, 0.99-1.05)., Conclusions: A high hr-HPV infection prevalence was recorded among the women. Utilizing technologies such as self-sampling, HPV DNA testing, and mobile colposcopy enables screening and treatment in remote and hard-to-reach communities where access to cervical cancer screening and treatment would otherwise be limited. Further research is warranted to assess the value and scalability of this approach in similar remote areas and its potential implementation in future programs., (© 2024. The Author(s).)

Background: The purpose of the Accelerating Colorectal Cancer Screening and Follow-up through Implementation Science (ACCSIS) Program, a Cancer Moonshot℠ Initiative, is to support research to build the evidence base on multilevel interventions that increase rates of colorectal cancer screening, follow-up, and referral to care to address disparities in colorectal cancer screening. The National Cancer Institute funded eight Research Projects to implement multilevel interventions to improve colorectal cancer screening among communities who traditionally have been medically underserved. To analyze the impact of ACCSIS across Research Projects, the consortium developed a set of common data elements. The purpose of this paper is to describe the process of developing the common data elements to facilitate analysis of ACCSIS data as well as support and inform implementation science research studies., Methods: The ACCSIS Data, Design, and Analysis Work Group was tasked with designing common data elements through a review of existing data collection instruments, examination of data elements proposed by the ACCSIS Research Projects, and deliberations on the data required to compare across the Research Projects. ACCSIS Consortium members drafted, revised, and finalized a common data elements document consisting of variables to collect and surveys to administer to evaluate ACCSIS implementation activities and outcomes in a standardized manner across the Research Projects., Results: The ACCSIS Consortium decided to collect the following categories of common data elements: characteristics across multiple levels of the multicomponent interventions, implementation climate, and determinants; interventions and strategies; implementation outcome constructs and definitions; colorectal cancer screening episodes (screening, diagnostic testing follow-up, cancer detection, and cancer treatment); and cost measures. To assess implementation climate, the consortium prioritized constructs from five domains of the Consolidated Framework for Implementation Research., Conclusions: The ACCSIS common data elements offer a set of harmonization data for future implementation efforts. The consortium is conducting a systematic assessment using both quantitative and qualitative approaches to assess data quality and approaches to improve and sustain data collection. Lessons learned from these ongoing activities will offer additional insights to tailor the ACCSIS common data elements and support efforts to increase colorectal cancer screening for populations experiencing disparities., (© 2024.

Background: Cervical cancer is the 2nd most common female cancer among Sri Lankan females and is almost associated with sexually transmitted cervicovaginal human papillomavirus (HPV) infection. The study objectives were to determine the prevalence of vaginal and cervical HPV infection among 35year old ever-married women and assess the validity of primary healthcare provider-collected vaginal HPV/DNA specimens as a cervical cancer screening tool to improve the coverage of the programme., Method: A descriptive cross-sectional study was carried out from the 1st of September 2018 to the 31st of January 2019. Ever-married women 35 years of age in Kalutara district were the study population. Two women from each Public Health Midwife area (n = 413) were selected randomly from the relevant area eligible families register/s. HPV/DNA cervical specimen and vaginal specimen collection (n = 621) were carried out. Specimens were screened by the Cobas 4800 HPV/DNA automated Polymerase Chain Reaction (PCR) machine. Participants' profiles were recorded by the research assistants using an interviewer-administered questionnaire., Results: The overall prevalence of vaginal and cervical HPV infection was 7.08% (95% CI; 5.2-9.4%) and 6.12% (95% CI; 4.26-8.3%) respectively. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), diagnostic accuracy, and the kappa coefficient of the vaginal HPV/DNA screening method vs. cervical HPV/DNA screening method were 100%, 98.9%, 86.4%, 100%, 99% and 0.92 respectively., Conclusions: Vaginal HPV/DNA specimen screening method can be used as a cervical cancer screening tool due to its high validity. Pilots of the feasibility should be set up before the regional or national rollout of vaginal sampling strategies., (© 2024. The Author(s).)

Background: Primary screening for high-risk human papillomavirus (hrHPV) with cytological triage for women with non-16/18 hrHPV-positive status has become popular in China. However, cytology relies on the subjective judgment of pathologists, leading to inconsistent clinical performance., Methods: A total of 657 hrHPV-positive women aged 25-64 years were enrolled in this cross-sectional study. All participants underwent colposcopic biopsy after cytology triage, with cytology residual specimens undergoing DNA methylation testing. CIN2+ and CIN3+ sensitivity and specificity were compared between the different triage strategies (n=487): PAX1 methylation (PAX1 m ) , Glycophorin C methylation (GYPC m ), cytology, and combinations between them or with HPV16/18., Results: The area under the receiver operating characteristic curves (AUCs) for PAX1 m and GYPC m in detecting CIN2 or worse (CIN2+) were 0.867 (95% confidence interval [CI]: 0.796-0.937) and 0.873 (95% CI: 0.808-0.938), respectively. The sensitivities of PAX1 m and GYPC m were consistent with those of cytology for both CIN2+ and CIN3+ detection. The relative specificities of PAX1 m and GYPC m for CIN2+ detection compared to cytology were 2.83 (95% CI: 2.33-2.45) and 3.09 (95% CI: 2.40-3.98), respectively. The relative specificities of combining HPV 16/18 with PAX1 m and GYPC m for CIN2+ detection compared to cytology were 3.38 (95% CI: 2.96-3.86) and 3.67 (95% CI: 3.15-4.27), respectively. Compared to low levels of DNA methylation, high levels of PAX1 m and GYPC m resulted in odd ratios (ORs) of 57.66 (95% CI: 13.57-409.12, p < 0.001) and 23.87 (95% CI: 6.49-115.42, p < 0.001) for CIN3+, adjusted for HPV 16/18 and cytology results., Conclusions: PAX1 m and GYPC m demonstrated superior ability to identify cervical precancerous lesions and cervical cancer, with AUC values exceeding 0.85. For detecting CIN2+/CIN3+ in women with hrHPV-positive status, DNA methylation (combined with HPV 16/18) showed higher specificity than cytology (combined with HPV 16/18) and is a potential molecular biomarker for detecting cervical (pre)cancer., (© 2024.

Bladder cancer (BCa) exhibits the escalating incidence and mortality due to the untimely and inaccurate early diagnosis. Urinary exosome metabolites, carrying critical tumor cell information and directly related to bladder, emerge as promising non-invasive diagnostic biomarkers of BCa. Herein, the magnetic 3D ordered macroporous zeolitic imidazolate framework-8 (magMZIF-8) is synthesized and used for efficient urinary exosome isolation. Notably, beyond retaining the single crystals and micropores of conventional ZIF-8, MZIF-8 is further enhanced with highly oriented and ordered macropores (150 nm) and the large specific surface area (973 m 2 ·g -1 ), which could enable the high purity and yield separation of exosomes via leveraging the combination of size exclusion, affinity, and electrostatic interactions between magMZIF-8 and the surfaces of exosome. Furthermore, the magnetic and hydrophilic properties of magMZIF-8 will further simplify the process and enhance the efficiency of separation. After conditional optimization, a 50 mL of urine is sufficient for exosome metabolomics analysis, and the time for isolating exosomes from 42 urine samples was 2 hours only. Incorporating machine learning algorithms with LC-MS/MS analysis of the metabolic patterns obtained from isolated exosomes, early-stage BCa patients were differentiated from healthy controls, with area under the curve (AUC) value of 0.844-0.9970 in the training set and 0.875-1.00 in the test set, signifying its potential as a reliable diagnostic tool. This study offers a promising approach for the non-invasive and efficient diagnosis of BCa on a large scale via exosome metabolomics., (© 2024. The Author(s).)

Background: The Cholangiocarcinoma Screening and Care Program (CASCAP) has been launched since 2013 to detect early-stage cholangiocarcinoma and reduce the disease death. However, the clinical utility of the CASCAP remains unclear. To compare survival outcomes between two time periods: before and after 2013, when significant changes in treatment strategies were implemented, and to evaluate the efficacy of the ultrasound-based screening program, in an Asian region endemic for cholangiocarcinoma., Methods: A single-center retrospective review was conducted in curative-intended resection cholangiocarcinoma from 2002 to 2021. Patents characteristics and survival outcomes were compared between 2002 and 2013 (early period) and 2014 to 2021 (later period)., Results: A total of 1091 patients with intrahepatic (n = 624) or perihilar (n = 467) cholangiocarcinoma was included (early period, n = 658; later period, n = 433). Of 66 (15.2%) patients in the later period were referred by the CASCAP. The incidence of early-staged disease (Stage 0 and 1) was lower in early period compared to later period 16.0% versus 29.1% (p < 0.001); that of positive surgical margin was higher in early period 53.7% versus 40.0% (p < 0.001). A median survival time (MST) was 14 months in early and 40 months in later period (p < 0.001). Subgroup analysis by tumor location, the MST was 13 versus 60 months in early and late periods for intrahepatic tumor (p < 0.001), respectively. While MST in perihilar tumor was 18 versus 31 months in early and late periods(p < 0.001), respectively. By presentation, the MST was 51 vs. 38 months, respectively, with screening and usual presentation (p = 0.06)., Conclusion: Postoperative survival in CCA patients improved more than doubled during the study period. Moreover, the late period demonstrated enhanced early-stage detection, a higher rate of negative surgical margins, and improved survival outcomes., (© 2024. The Author(s).)

Background: Although low-dose computed tomography (LDCT) screening effectively reduces LC mortality in high-risk individuals with a history of smoking in China, the feasibility and efficacy of lung cancer screening (LCS) in individuals who never smoked versus individuals who smoked remains unclear., Methods: We conducted a retrospective analysis of prospective cohort studies at the National Cancer Center (NCC) in China from January 2006 to December 2022. A comprehensive LCS initiative was undertaken, involving 30,468 participants (54.5% male). Participants underwent LCS using LDCT. Potential malignancies were managed through joint consensus between patients and their physicians. Epidemiology, screening eligibility criteria, and LC detection rates and survival outcomes were compared between individuals who smoked and individuals who never smoked., Results: Among 30,468 participants, 339 LCs were pathologically confirmed in 289 patients. The LC detection rate was 0.9% (289/30,468) overall, 0.8% in individuals who smoked (71/9,042), and 1.0% in individuals who never smoked (218/21,426). In individuals who smoked, LC detection rates were 0.5% (21/4516) and 1.1% (50/4526) in the < 20 and ≥ 20 pack-year subgroups, respectively (P = 0.001). Early-stage LC (stage 0 or I) was detected in 73.8% of the individuals who smoked and in 78.8% of individuals who never smoked, while advanced LC (stage III-IV) was found 8.8% of individuals who smoked and 4.2% of individuals who never smoked, respectively. Significant differences in histologic types were found between individuals who smoked and individuals who never smoked (P = 0.01), although adenocarcinoma was the most prevalent in both groups, at 83.0% and 78.8%, respectively. The median nodule size was 9.9 mm (IQR, 8.0-13.8) in individuals who smoked and 9.2 mm (IQR, 6.8-13.6) in individuals who never smoked (P = 0.228). Individuals who never smoked tended to favour surgical treatment alone (88.0%) more than individuals who smoked (81.3%). The 10-year survival rate was higher in individuals who never smoked (92.6%) than in individuals who smoked (88.8%). Only 15.6% (45/289) of patients with LC met the United States Preventive Services Task Force (USPSTF) criteria for LDCT eligibility, while 29.0% (84/289) met the China guideline for the screening and early detection of lung cancer (CGSL) criteria. Median follow-up for those followed was 25.4 (IQR, 13.7-43.3) months., Conclusions: LDCT screening improves early LC detection and treatment outcomes for both individuals who smoked and individuals who never smoked. Significant differences exist in epidemiology, histologic type, and survival between these groups. The USPSTF and CGSL criteria miss a significant number of LC cases, particularly among individuals who never smoked. Integrating individuals who never smoked into LCS programs is essential, yet it comes with its own challenges, such as managing radiation risks, allocating resources effectively, and considering financial aspects. Consequently, there is an urgent need for LCS programs in China to better identify the "high-risk" non-smoker population susceptible to LC and to ensure that potential risks associated with screening are reduced., (© 2024.

Backgrounds: Cancer antigen 125 (CA125) is widely used for screening ovarian cancer (OC), yet its effectiveness remains debated. Potential factors may include ineffective cut-off value for CA125 in screening, as well as a lack of consideration for CA125 trajectories and trajectory-specific progression., Methods: Based on data from multiple rounds of CA125 tests and transvaginal ultrasound (TVU) examinations conducted on 28,456 women in the PLCO Trial, time-dependent receiver-operating-characteristic curves (ROCs) and area-under-the-curves (tdAUCs) analyses were employed to identify the optimal CA125 cut-off values for OC screening. Participants were categorized into four CA125 trajectories: stable negative CA125 (CA125 SN ), loss of positive CA125 (CA125 LP ), stable positive CA125 (CA125 SP ), and gain of positive CA125 (CA125 GP ). The associations between different CA125 trajectories, trajectory-specific progression indicators, and OC risk were explored. The effectiveness of risk-stratified CA125 screening, incorporating CA125 trajectories, trajectory-specific progression, and TVU, was evaluated using hazard ratio and 95% confidence intervals [HR (95%CIs)], with adjustments for potential confounders., Results: After a median follow-up of 14.8 years for OC incidence and 23.8 years for OC mortality, 250 OC cases and 218 OC deaths were identified. The tdAUC for 10-year OC incidence with CA125 was 0.663, with an optimal cut-off value of 13.00 U/ml. Trajectory analyses showed that both CA125 SP and CA125 GP were significantly associated with increased risks of OC incidence [HRs (95%CIs): 2.00(1.47-2.73) and 3.06(2.25-4.16)] and mortality [HRs (95%CIs):1.58(1.13-2.21) and 2.60(1.87-3.62)] compared to CA125 SN . Trajectory-specific progression analyses identified relative velocity as the optimal progression indicators for both CA125 SP and CA125 GP (tdAUCs: 0.712 and 0.767), with optimal cut-off values of 9% and 32% per year, respectively. Positive progression was associated with significantly increased risks of OC incidence [HRs (95%CI): 7.26(4.00-13.17) and 3.83(1.96-7.51) CA125 GP and CA125 SP ] and mortality [HRs (95%CI): 8.03(4.15-15.56) and 6.04(2.78-13.14)] compared to negative progression. Optimized risk-stratified CA125 screening, which integrated CA125 trajectories, trajectory-specific progression, and TVU, reduced missed OC by 3.6% and improved accuracy compared to traditional screening methods., Conclusions: Incorporating CA125 trajectories and trajectory-specific progression into screening protocols enhances the identification of the population at high-risk of OC. An optimized screening strategy, which includes these factors along with TVU, is recommended to improve the effectiveness of OC screening., (© 2024. The Author(s).)

Background: The increased knowledge of cervical cancer (CC) risk factors and suboptimal performance of present screening programs has generated interest in shifting from a universal screening approach to one based on individual risk assessment. To inform the future development of risk-based CC screening programs, it is crucial to gain insight into the factors influencing the acceptability of such approach among screening target group women. The aim of this study was to prospectively investigate the acceptability of risk-based CC screening and to identify potential barriers., Methods: In this qualitative study, one-to-one semi-structured interviews were conducted with a purposeful sample including women aged 30-65 years to explore women's perspectives on the acceptability of risk-based CC screening. The study was conducted in Estonia, and interviews were conducted from March to September 2023. Potential participants were approached in person by a member of the study team or by their healthcare providers at primary care or gynaecology clinics. The interview guides were developed based on the concept of acceptability of healthcare interventions., Results: Twenty participants (mean age 44.5, SD = 8.6) with diverse backgrounds were interviewed. The seven components of acceptability (affective attitude, burden, ethicality, opportunity costs, perceived effectiveness, self-efficacy, and intervention coherence) were explored as key themes. Generally, women supported risk-based screening. However, we identified several factors that may compromise the acceptability of risk-based screening. The participants were reluctant to accept less intense screening for low-risk women and anticipated that if risk-based approach was implemented, more frequent testing would remain an option. Providing in-person clinician support was expected, requiring additional healthcare resources. Knowledge gaps in CC prevention highlighted the need for accessible information and education. Most women were unworried about sensitive data inclusion in risk score calculations. However, some participants were concerned about potential confidentiality breaches by healthcare workers., Conclusion: This study indicates that risk-based CC screening is acceptable, except for testing low-risk women less frequently. Our findings underscore the necessity for comprehensive understanding of the needs and concerns of the target group women for program development. Healthcare organizations are required to proactively address these needs by implementing comprehensive information dissemination and efficient communication approaches., (© 2024. The Author(s).)

Introduction: Human papilloma virus testing is a new method of screening for precancerous cervical lesions. Here we identified factors associated to the positive Human papilloma virus-testing in the context of cervical precancer screening at the Souro Sanou National Teaching Hospital in Burkina Faso., Materials and Method: Conducted from June 2021-May 2022, this was a cross-sectional study, including patients aged between 25 and 55 years-old and screened for precancerous lesions and received HPV-testing at the Department of Gynecology, Obstetrics and Reproductive Medicine (DGORM) of the SSNTH. The proportion of positive HPV-test was calculated, and we identified factors associated to positive HPV-test using logistic regression., Results: Of the 759 patients came for precancerous lesions screening, 559 patients were included. Their mean-age was 38.8 ± 7.9 years-old, 94.3% were from urban area and 50.3% identified as housewives. Regarding the past medical history, it noted: number of gestures (3.2 ± 2.0), parity (2.8 ± 1.9), number of living children (2.8 ± 1.9), having abortion experience (24.0%), age of first-sexual-intercourse(18.6 ± 2.3 years), alcohol (9.1%) and tobacco (1.0%) consumption, sexually-transmitted-infection (27.0%), Human immunodeficiency virus (HIV)infection (5.0%); none had been vaccinated against HPV. Biologically, 16.6% [95% CI: 13.6-20] of the women had a positive HPV-test. The factors significantly associated with positive HPV-test were: occupation in the private sector [OR: 0.06(0.0-0.5); p < 0.001], having a sexually-transmitted-infection [OR: 3.9(2.0-7.7); p < 0.001], age of first-sexual-intercourse [OR: 0.7(0.6-0.9); p < 0.001], sexual-multiple-partnership [OR: 17.5(8.1-39.6); p < 0.001], and HIV status [OR: 13.2(4.4-40.5); p < 0.001]., Conclusion: These results call for health actions through the reinforcement for behavioral change mainly about sexually-transmitted-infections, and for the raising awareness of the population for the screening related to the precancerous lesions and HIV., (© 2024.

Background: Enhancing the prognosis and treatment outcomes of oral cancer relies heavily on its early detection. This study aims to establish a connection between serum and salivary dipeptidyl peptidase-4 (DPP-4) levels and oral squamous cell carcinoma (OSCC), comparing them with oral potentially malignant lesions (OPMLs) and control subjects and validating salivary DPP-4 as a diagnostic marker for the early detection of oral cancer., Methodology: Forty-five systemically healthy individuals were categorized into three groups: Group I consisted of 15 patients diagnosed with OSCC, Group II comprised 15 patients with OPMLs (including leukoplakia and oral lichen planus), and Group III included 15 participants without any oral mucosal lesions. Serum and whole unstimulated salivary samples were collected from all participants to assess DPP-4 levels using an enzyme-linked immunosorbent assay (ELISA) kit. Receiver operating characteristic (ROC) analysis was conducted to determine the area under the curve (AUC), sensitivity, specificity, and diagnostic accuracy of DPP-4., Results: Both serum and salivary DPP-4 levels were highest in the healthy group, followed by OPMLs, and lowest in the OSCC group, with statistically significant differences observed. ROC analysis demonstrated excellent diagnostic accuracy of salivary DPP-4 in distinguishing OSCC from healthy individuals, OPMLs from healthy individuals, and OSCC from OPMLs, with accuracies of 100%, 100%, and 96.67%, respectively. Salivary DPP-4 levels also exhibited a statistically significant correlation with OSCC grades., Conclusions: DPP-4 appears to play a protective, anti-oncogenic role in maintaining oral tissue health. The remarkable diagnostic accuracy of both serum and salivary DPP-4 in discriminating between OSCC, OPMLs, and healthy controls suggests its potential utility as a well-established marker for early oral cancer diagnosis. Salivary DPP-4, being non-invasive, could serve as a convenient chair-side diagnostic tool for the early detection of OSCC., Clinical Trial Registration: The study was retrospectively registered on clinicaltrial.gov with NCT06087042, date of registration (first posted date): 17/10/2023., (© 2024.

Background: The majority of men referred with a raised PSA for suspected prostate cancer will receive unnecessary tertiary investigations including MRI and biopsy. Here, we compared different types of biomarkers to refine tertiary referrals and when different definitions of clinically significant cancer were used., Methods: Data and samples from 798 men referred for a raised PSA (≥ 3 ng/mL) and investigated through an MRI-guided biopsy pathway were accessed for this study. Bloods were acquired pre-biopsy for liquid biomarkers and germline DNA. Variables explored included PSA + Age (base model), free/total PSA (FTPSA), Prostate Health Index (phi), PSA density (PSAd), polygenic risk score (PRS) and MRI (≥ LIKERT 3). Different diagnostic endpoints for significant cancer (≥ grade group 2 [GG2], ≥ GG3, ≥ Cambridge Prognostic Group 2 [CPG2], ≥ CPG3) were tested. The added value of each biomarker to the base model was evaluated using logistic regression models, AUC and decision curve analysis (DCA) plots., Results: The median age and PSA was 65 years and 7.13 ng/mL respectively. Depending on definition of clinical significance, ≥ grade group 2 (GG2) was detected in 57.0% (455/798), ≥ GG3 in 27.5% (220/798), ≥ CPG2 in 61.6% (492/798) and ≥ CPG3 in 42.6% (340/798). In the pre-MRI context, the PSA + Age (base model) AUC for prediction of ≥ GG2, ≥ GG3, ≥ CPG2 and ≥ CPG3 was 0.66, 0.68, 0.70 and 0.75 respectively. Adding phi and PSAd to base model improved performance across all diagnostic endpoints but was notably better when the composite CPG prognostic score was used: AUC 0.82, 0.82, 0.83, 0.82 and AUC 0.74, 0.73, 0.79, 0.79 respectively. In contrast, neither FTPSA or PRS scores improved performance especially in detection of ≥ GG3 and ≥ CPG3 disease. Combining biomarkers did not alter results. Models using phi and PSAd post-MRI also improved performances but again benefit varied with diagnostic endpoint. In DCA analysis, models which incorporated PSAd and phi in particular were effective at reducing use of MRI and/or biopsies especially for ≥ CPG3 disease., Conclusion: Incorporating phi or PSAd can refine and tier who is referred for tertiary imaging and/or biopsy after a raised PSA test. Incremental value however varied depending on the definition of clinical significance and was particularly useful when composite prognostic endpoints are used., (© 2024. The Author(s).)

Background: Mexico reports low follow-up completion rates among women with abnormal cervical cancer screenings. This study aimed to identify barriers and facilitators to follow-up adherence among women with human papillomavirus (HPV) infection and premalignant cervical lesions in Mexico., Methods: A mixed-methods study was conducted from February to April 2019. Participants included women undergoing follow-up care for high-risk human papillomavirus (HR-HPV) and premalignant lesions, along with health personnel from the Women's Healthcare Center (CAPASAM) in Mexico. Quantitative data were obtained from the Women's Cancer Information System and through a questionnaire about factors affecting follow-up adherence. Additionally, the health personnel involved completed a compliance checklist regarding care regulations. Descriptive statistics were used for analysis. Qualitative data were collected via semi-structured interviews with both groups, followed by a content analysis based on identified categories. The Hazard Analysis and Critical Control Point System confirmed care process risks. Proposals to enhance the Early Detection Program for Prevention and Control of Cervical Cancer were collected from a CAPASAM health personnel nominal group., Results: Identified barriers to follow-up included low income among CAPASAM users, family provider roles limiting time for appointments, long waits for testing and results delivery, distant facilities, insufficient service hour communication, inadequate health personnel training, and a lack of systematic counseling. Hesitation toward follow-up was also linked to shame, apprehension, uncertainty, test aversion, fear of positive results, and limited cervical cancer and screening knowledge. Patriarchal attitudes of partners and limited access to the now-discontinued PROSPERA government program further discouraged follow-up. Facilitators comprised respectful treatment by CAPASAM staff, no-cost services, health campaigns, and positive user attitudes., Conclusions: The study found more barriers than facilitators to follow-up adherence, highlighting the need for strategies to bolster the Early Detection Program. Future strategies must address the comprehensive array of factors and incorporate stakeholder perspectives., (© 2024. The Author(s).)

Background: Cervical cancer is the fourth most common cancer in women worldwide, and women with human immunodeficiency virus (HIV) are particularly at risk of developing it. Regular screening effectively prevents morbidity and mortality. This mixed-methods study quantitatively assessed cervical cancer screening uptake and qualitatively explored the process of undergoing cervical cancer screening to understand possible reasons for delayed screening among women with HIV in Lesotho., Methods: Between October 2020 and March 2022, the Viral load Triggered ART care in Lesotho (VITAL) trial enrolled women aged 18 years and older with HIV who were taking antiretroviral therapy (ART). Cervical cancer screening delay was defined as reporting a screening that occurred more than two years ago or never having been screened. Cervical cancer screening uptake and the association between screening delay and sociodemographic variables were assessed using a multivariable mixed-effects logistic regression model accounting for clustering at clinic level. In-depth interviews were conducted with 16 women to obtain information on awareness, perceptions, and barriers to cervical cancer screening and were analyzed using thematic analysis., Results: Quantitative data were available for 3790 women. Among them, cervical cancer screening was delayed in 1814 (47.9%), including 1533 (40.5%) who were never screened. Compared to women aged 25 to 39 years, women aged 18 to 24 years (adjusted odds ratio (aOR) 2.8; 95% confidence interval (CI) 2.1-3.7), women aged 40 to 59 years (aOR 1.3; CI 1.1-1.6), and women older than 60 years (aOR 3.9; CI 3.0-5.1) were at higher risk of screening delay. Furthermore, time on ART below 6 months (aOR 1.6; CI 1.1-2.3) compared to above 6 months was associated with screening delay. Qualitative data identified limited awareness of cervical cancer risks and screening guidelines, misconceptions and fears created by the influence of other women's narratives, and low internal motivation as the main barriers to screening uptake., Conclusions: Cervical cancer screening delay was common. Limited personal awareness and motivation as well as the negative influence of other women were the primary internal barriers to cervical cancer screening. Awareness and screening campaigns in Lesotho should consider these factors., Trial Registration: clinicaltrials.gov, NCT04527874, August 27, 2020., (© 2024. The Author(s).)

Background: Teaching effective methods for breast self-examination (BSE) to adolescent females is essential for promoting early detection and improving outcomes in breast cancer management. This study therefore aimed to compare two pedagogical tools for teaching BSE among adolescent females., Methods: A quasi-experimental design with a group for pre- and post-intervention tests was adopted. The sample included 970 female senior secondary school class I-III students. The Yamane formula was used to determine a sample size of 276. Pre- and post-intervention data were collected using an observation checklist for practice and a validated questionnaire with a Cronbach's alpha coefficient of 0.76 for knowledge of BSE. A proportionate stratified random sampling technique was used to determine the number of participants for each group. Among the 276 participants, 161 were taught the traditional method (TM), i.e., a lecture, and 115 were taught using the modern method (MM) by watching a podcast that contained BSE lessons. Post-intervention data were collected after six weeks. The data were analysed using descriptive and inferential statistics at a 5% level of significance to compare the effectiveness of the methods., Results: The findings of this study showed that the participants' mean ages across the two methods were 15.49 ± 1.65 and 15.43 ± 1.40 years for the traditional method (TM) and modern method (MM), respectively. Pre-intervention mean BSE knowledge scores in both the TM and MM groups were 8.19 ± 3.17 and 8.31 ± 2.39, respectively, and BSE practice scores were 7.17 ± 2.48 and 6.44 ± 2.75, respectively. Post-intervention knowledge mean scores in both the TM and MM groups increased to 13.75 ± 4.09 and 16.92 ± 2.91, respectively, and post-intervention practice scores increased to 13.06 ± 2.74 and 15.68 ± 3.12, respectively., Conclusion: This study revealed that both teaching methods were effective at teaching breast self-examination among female adolescents; nevertheless, modern methods are more effective at teaching breast self-examination among female adolescents., (© 2024.

Background: Lung cancer (LC), a paramount global life-threatening condition causing significant mortality, is most commonly characterized by its subtype, lung adenocarcinoma (LUAD). Concomitant with LC, pulmonary fibrosis (PF) and interstitial lung disease (ILD) contribute to an intricate landscape of respiratory diseases. Idiopathic pulmonary fibrosis (IPF) in association with LC has been explored. However, other fibrotic interrelations remain underrepresented, especially for LUAD-PF and LUAD-ILD., Methods: We analysed data with statistical analysis from 7,137 healthy individuals, 7,762 LUAD patients, 7,955 ILD patients, and 2,124 complex PF patients collected over ten years. Furthermore, to identify blood indicators related to lung disease and its complications and compare the relationships between different indicators and lung diseases, we successfully applied the naive Bayes model for a biomarker-based prediction of diagnosis and development into complex PF., Results: Males predominantly marked their presence in all categories, save for complex PF where females took precedence. Biomarkers, specifically AGR, MLR, NLR, and PLR emerged as pivotal in discerning lung diseases. A machine-learning-driven predictive model underscored the efficacy of these markers in early detection and diagnosis, with NLR exhibiting unparalleled accuracy., Conclusions: Our study elucidates the gender disparities in lung diseases and illuminates the profound potential of serum biomarkers, including AGR, MLR, NLR, and PLR in early lung cancer detection. With NLR as a standout, therefore, this study advances the exploration of indicator changes and predictions in patients with pulmonary disease and fibrosis, thereby improving early diagnosis, treatment, survival rate, and patient prognosis., (© 2024.

Background: This study aimed to assess the recognition and understanding of breast awareness (BA) among hospital staff, a group considered influential in disseminating information about health. Compared to the traditional approach of breast self-examination (BSE), BA has gained prominence as a concept focused on early detection. The study also explored the effectiveness of an informational leaflet in conveying BA concepts., Methods: We conducted an online, voluntary, and anonymous questionnaire survey at St. Luke's International Hospital in Japan, where approximately 1,000 breast cancer surgeries are performed annually. The survey comprised three sections: pre-leaflet questions, the informational leaflet, and post-leaflet questions., Results: From a pool of 500 completed questionnaires, 499 were deemed suitable for the analysis. Notably, 78% of respondents were unfamiliar with "BA" before the survey. However, 89.1% expressed interest in adopting daily practices for early breast cancer detection. Following the leaflet exposure, 98.4% of respondents claimed to have understood BA, either completely or partially. The leaflet aided 93.2% of these individuals in differentiating between BA and the traditional BSE method. These outcomes remained consistent across various demographic segments such as occupation, age, and experience with breast cancer care., Conclusions: The study underscores a concerning lack of awareness regarding BA among hospital staff within the surveyed institution. This highlights the need to engage medical professionals in promoting BA within the community. The informational leaflet proved effective in enhancing comprehension of BA across diverse groups, indicating its potential as a widely applicable educational tool. The leaflet facilitated the comprehension of BA among respondents across all demographic groups, indicating its potential for widespread utility., (© 2024. The Author(s).)

Purpose: This study aimed to investigate the clinical significance of combining peripheral blood miR-21 and miR-486 with CT for the early cancer diagnosis in pulmonary nodules., Methods: A total of 215 patients diagnosed with isolated pulmonary nodules with a history of smoking were selected as researchsubjects. 30 healthy volunteers with a history of smoking were recruitedas the control group.The selection of subjectswas based on the presence of isolated pulmonary nodules detected on chest CT scans. The training set consisted of 65 patients with lung nodules and 30 healthy smokers, while the verification setincluded 150 patients with lung nodules., Results: Compared with the control group, the plasma expression level of miR-210 was significantly higher in the group of patients with benign pulmonary nodules (P < 0.05). The level of miR-486-5p was lower in patients with malignant pulmonary nodules compared to those with benign pulmonary nodules (P < 0.05). Moreover, the plasma level of miR-210was higher in patients with malignant pulmonary nodules compared to those with benign pulmonary nodules and healthy smokers (P < 0.05). The combination of miR-21 and miR-486 yielded an AUC of 0.865, which was significantly higher than any other gene combination (95%CI: 0.653-0.764, P < 0.05)., Conclusions: This study offered preliminary evidence supporting the use of peripheral blood miR-21 and miR-486, combined with CT scans, as potential biomarkers for the early cancer diagnosis in lung nodules., (© 2024.

Background: Measurement of tumor markers from peripheral venous blood is an emerging tool to assist in the early diagnosis of lung cancer. Samples from the pulmonary artery and pulmonary artery wedge position (trans-pulmonary samples) are accessible via right-heart catheterization and, by virtue of their proximity to lung tumors, may increase diagnostic yield., Case Presentation: We report a case of a 64 year-old woman from whom trans-pulmonary samples were obtained and who was diagnosed 16 months later with recurrent metastatic small cell lung cancer. Carcinoembryonic antigen, cytokeratin fragment 21 - 1 (CYFRA), and human epididymis protein 4 (HE4) levels demonstrated increasing concentrations across the pulmonary circulation. These gradients exceeded the assays' coefficient of variation by several-fold. For CYFRA and HE4, pulmonary artery wedge concentrations exceeded peripheral venous levels by more than 10% and peripheral arterial levels were up to 8% higher than peripheral venous levels., Conclusions: Evaluating the feasibility and utility of trans-pulmonary tumor markers for lung cancer diagnosis in a larger cohort should be considered. The addition of a peripheral arterial sample to standard peripheral venous samples may be a more practical alternative., (© 2024. The Author(s).)

Background: Cervical cancer remains a leading cause of cancer-related deaths among women in Ghana and other Sub-Sahara African (SSA) countries. Despite the importance of early diagnosis for timely treatment and death prevention, cervical cancer screening among women in developing countries remain very low. Nonetheless, there is a paucity of research examining the factors associated with screening uptake among women of reproductive age in Ghana. Thus, this study fills the scholarly void and contributes to the existing literature by examining the determinants of cervical cancer screening in Ghana., Methods: Utilizing data from the 2022 Ghana Demographic and Health Survey (GDHS) (N = 15,014 women), and by employing logistic regression models for a cross-sectional analysis, this study evaluated the factors associated with cervical cancer screening in Ghana., Results: Women with tertiary educational attainment (OR = 4.140; 95%CI: 2.960 5.789; p < 0.001), from the richer (OR = 1.968; p < 0.001) and richest households (OR = 2.492; p < 0.001), the married/living with partner (OR = 1.773; 95%CI:1.372 2.290; p < 0.001), the widowed/divorced/separated (OR = 1.888; 95%CI:1.320 2.701; p < 0.001), owners of valid health insurance card (OR = 1.356; 95%CI:1.086 1.693; p < 0.01), visitation to health facility in the past 12 months (OR = 1.312; 95%CI: 1.082 1.590; p < 0.001), those who watched television at least once in a week (OR = 1.395; 95%CI: 1.055 1.846; p < 0.001), as well as those who listened to radio at least once in a week (OR = 1.509; 95%CI: 1.228 1.853; p < 0.001), were all significantly more associated with cervical cancer screening in the study context. Also, ethnicity, religion, and the region of residence significantly predicted cervical cancer screening in the study context., Conclusion: Cervical cancer screening in Ghana can be improved by addressing socioeconomic and geographical disparities in the country's healthcare system. To ensure early detection, timely treatment or care and prevention of cervical cancer-related deaths in the country, there must be coordinated efforts by the government of Ghana to improve healthcare access and surveillance systems for cervical cancer cases, particularly, in geographically disadvantage areas., (© 2024.

Background: Cervical cancer continues to threaten women's health, especially in low-resource settings. Regular follow-up after screening and treatment is an effective strategy for monitoring treatment outcomes. Consequently, understanding the factors contributing to patient non-attendance of scheduled follow-up visits is vital to providing high-quality care, reducing morbidity and mortality, and unnecessary healthcare costs in low-resource settings., Methods: A descriptive qualitative study was done among healthcare providers and patients who attended the cervical cancer screening clinic at Mbarara Regional Referral Hospital in southwestern Uganda. In-depth interviews were conducted using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim, and thematically analysed in line with the social-ecological model to identify barriers and facilitators., Results: We conducted 23 in-depth interviews with 5 healthcare providers and 18 patients. Health system barriers included long waiting time at the facility, long turnaround time for laboratory results, congestion and lack of privacy affecting counselling, and healthcare provider training gaps. The most important interpersonal barrier among married women was lacking support from male partners. Individual-level barriers were lack of money for transport, fear of painful procedures, emotional distress, and illiteracy. Inadequate and inaccurate information was a cross-cutting barrier across the individual, interpersonal, and community levels of the socio-ecological model. The facilitators were social support, positive self-perception, and patient counselling., Conclusions: Our study revealed barriers to retention in care after cervical cancer screening, including lack of partner support, financial and educational constraints, and inadequate information. It also found facilitators that included social support, positive self-perception, and effective counselling., (© 2024. The Author(s).)

Background: Liver cancer (LC) screening, such as AFP test and abdominal ultrasound, is an effective way to prevent LC, one of the most common cancers worldwide. Despite the proven screening benefits, screening participation among high-risk populations for LC remains low. This suggests that targeted, systematic, and effective interventions should be provided to improve knowledge and awareness related to LC screening, enhance screening intentions, and thereby promote screening behaviors. Telephone is people's main medium of daily communication and mHealth-based programs offer a potential and effective solution for promoting health behaviors. The purpose of this study is to develop and implement a mHealth (WeChat app) based intervention guided by Fogg's Behavior Model (FBM) to augment the knowledge of LC prevention among people at risk of LC and enhance their motivation for screening, and to validate its effectiveness in improving LC screening., Methods: We propose a two-arm, single-blind randomized controlled trial with 82 at-risk individuals of LC, delivering a 6-month mHealth-based intervention program with optional health counseling. Recruitment will be through tertiary hospitals and community organizations in 4 districts in Heng Yang. In total, 82 individuals at high risk for HCC will be randomized 1:1 to intervention or control (usual care) groups. The intervention group will receive intervention, whose contents are based on the FBM model, via multiple forms of media including PowerPoint presentation, multimedia video, health information booklet and screening message, which is delivered in the WeChat Applet. Control dyads will be provided with usual health education. Outcomes will be assessed at baseline and post-intervention., Discussion: The findings of this study will provide evidence of the benefits of utilizing mHealth-based approaches in intervention development to enhance the effectiveness of screening adherence for high-risk people of LC. Further, the findings would provide reference to the potential incorporation of the targeted intervention in local community organizations., Trial Registration: Chinese Clinical Trial Registry (ChiCTR2400080530) Date registered: 31/1/2024., (© 2024.

Intimate partner violence affects 20-30% of women in the United States. Disparities in routine cervical cancer surveillance have been demonstrated in certain populations, including victims of intimate partner violence (IPV). This study examined and assessed the acceptability of high-risk HPV (hrHPV) self-collection among individuals who have experienced IPV. We conducted an observational study using qualitative data collection and analysis. We interviewed individuals with a history of IPV and who currently reside in Oregon. This study identified key themes describing knowledge and attitudes towards cervical cancer screening for individuals who have experienced IPV. They include: guideline knowledge, prior office-based cervical cancer screening experience, barriers to cervical cancer screening, at-home hrHPV self-collection experience, and testing confidence. Participants experienced fewer barriers and expressed increased comfort and control with hrHPV self-collection process. Individuals with a history of IPV have lower rates of cervical cancer screening adherence and higher rates of cervical dysplasia and cancer than other populations. The patient-centered approach of hrHPV self-collection for cervical cancer screening can reduce barriers related to the pelvic exam and empower patients to reduce their risks of developing cervical cancer by enabling greater control of the testing process., (© 2024.

Background: Oral cancers, which include tumors of the oral cavity, salivary glands, and pharynx, are becoming increasingly prevalent worldwide. Squamous cell carcinoma accounts for over 90% of malignant oral lesions, with oral squamous cell carcinoma (OSCC) being notably common in the Indian subcontinent and other regions of Asia. This is especially true in South-Central Asia, including Sri Lanka, where it is particularly prevalent among men. This study aims to evaluate the levels of Vascular Endothelial Growth Factor-A (VEGF-A) and Cytokeratin-19 (CK-19) mRNAs in whole blood as a potential method for the early detection of OSCC., Methods: The study included 40 patients (each from OSCC, Oral Submucous Fibrosis (OSF), Oral Leukoplakia (OLK), Oral Lichen Planus (OLP), and 10 healthy controls. The expression levels of VEGF-A and CK-19 mRNAs were measured from extracellular RNA extracted from whole blood samples using real-time reverse transcription polymerase chain reaction (RT-PCR) with sequence-specific primers. Receiver operating characteristic (ROC) curve analysis was used to evaluate the effectiveness of these biomarkers in detecting OSCC., Results: The results demonstrated a significant increase in blood transcripts of the candidate mRNAs CK-19 and VEGF-A in patients with OSCC, OSF, OLK, and OLP. The Wilcoxon signed-rank test revealed a p-value of 0.002 for each specific comparison between diseased patients and healthy controls (i.e., OSCC vs. HC, OSF vs. HC, OLP vs. HC, OLK vs. HC) for both CK-19 and VEGF-A. When these two biomarkers were used together, they provided a 60% predictive probability for patients with OSCC (p = 0.023)., Conclusion: This study highlights the efficacy of blood mRNA transcriptome diagnostics in detecting OSCC. This innovative clinical approach has the potential to be a robust, efficient, and reliable tool for early cancer detection. Blood-based transcriptomes could be further explored for their effectiveness in various health contexts and for routine health monitoring., (© 2024. The Author(s).)

Background: Human papillomavirus (HPV) self-sampling is recognized as a feasible option for enhancing screening for cervical cancer, particularly among hard-to-reach women. The magnitude of the effectiveness of screening participation under different invitation strategies was reported. This review seeks to compare the effectiveness of invitation strategies in increasing screening participation of HPV self-sampling across diverse study settings., Methods: A systematic literature search was conducted in Embase, MEDLINE, and PubMed in April 2023. Articles were included if (1) their target participants were aged between 25 and 70 years; (2) participants in the intervention arm were randomized to receive HPV self-sampling devices through various invitation strategies; (3) participants in the control arm who either received invitations for cervical cancer screening other than HPV self-sampling or opportunistic screening as usual care; (4) studies that provided sufficient data on screening participation in HPV self-sampling as outcome measured. The study design of the included articles was limited to randomized controlled trials., Results: A total of 15 articles were included in this review. Invitation strategies of disseminating HPV self-sampling devices included opt-out and opt-in. Meta-analysis revealed screening participation in the self-sampling group was significantly greater than control arm (OR 3.43, 95% CI 1.59-7.38), irrespective of the invitation strategy employed. Among invitation strategies, opt-out appeared to be more effective on increasing screening participation, compared to control and opt-in strategy (opt-out vs. control OR 3.91, 95% CI 1.82-8.42; opt-in vs. control OR 1.34, 95% CI 0.28-6.39)., Conclusions: Opt-out strategy is more successful at improving screening participation compared to opt-in and routine invitation to cervical screening. It is therefore a promising way to improve participation in cervical cancer screening. The findings of this review provide important inputs to optimize strategies for inviting women to participate in vaginal HPV self-sampling across the study setting, thus improving participation in cervical cancer screening., (© 2024.

Background: Several rural public health facilities in East Central Uganda have sub-optimal, below 50%, levels of uptake of cervical cancer screening services among women with HIV. This is attributed to low cervical cancer screening literacy: limited ability to access, understand, appraise, and apply cervical cancer screening information. This research identified multi-level (health facility, community, interpersonal and individual) barriers, and facilitators of accessing, understanding, and applying cervical cancer screening information among rural women with HIV attending rural public health facilities in East Central Uganda to inform interventions., Methods: We conducted ten Focus Group Discussions with rural women aged 25-49 years with HIV attending four selected rural public health facilities: thirty women who had ever screened for cervical cancer and thirty women who had never screened for cervical cancer across different age categories. Data was collected using a guide based on the Integrated model of health literacy. Thematic analysis was used for analysis. Competences (accessing, understanding and applying cervical cancer screening information) and categories of factors (health system, community, interpersonal and individual factors) of the integrated model of health literacy were deductively derived whereas barriers and facilitators were deductively derived from women's statements., Results: Lack of communication materials and inability to access information were health facility and individual barriers of accessing cervical cancer screening information respectively. Facilitators of accessing information were access to information at health facility, community, and interpersonal levels and women's ability to access information. Barriers and facilitators of understanding cervical cancer information were related to communication materials, provision of health education and women's concentration during health education. Barriers and facilitators of applying cervical cancer screening information were related to communication and provision of cervical cancer screening services at health facility level, and interpersonal level from peers, partners and other family members as well as women's ability to: understand information and access to cervical cancer screening services at individual level., Conclusions: This study emphasizes the influence of multi-level factors on cervical cancer screening literacy among rural women with HIV attending rural public health facilities in East Central Uganda. Improving uptake of cervical cancer screening services among these women requires multi-level interventions., (© 2024. The Author(s).)

Background: Nasopharyngeal carcinoma (NPC) is diagnosed relatively late and has a poor prognosis, requiring early detection to reduce the disease burden. This diagnostic test accuracy meta-analysis evaluated the serological diagnostic value of nine EBV-related IgA antibody panels (EBNA1-IgA, VCA-IgA, EA-IgA, Zta-IgA, EBNA1-IgA + VCA-IgA, VCA-IgA + EA-IgA, VCA-IgA + Rta-IgG, EBNA1-IgA + VCA-IgA + Zta-IgA and VCA-IgA + EA-IgA + Rta-IgG), aiming to identify suitable serological detection biomarkers for NPC screening., Methods: PubMed, Embase, China National Knowledge Infrastructure and Chinese BioMedical Literature Database were searched from January 1st, 2000 to September 30th, 2023, with keywords nasopharyngeal carcinoma, IgA, screening, early detection, early diagnosis, sensitivity and specificity. Articles on the diagnostic value of serum EBV-related IgA antibody panels for NPC were included. Study selection, data extraction, and quality assessment were performed independently by two researchers, and a third researcher was consulted in the case of disagreement. Bivariate models were used for statistical analysis. The quality of included studies was evaluated through Quality Assessment of Diagnostic Accuracy Studies tool (QUADAS-2)., Results: A total of 70 articles were included, involving 11 863 NPC cases and 34 995 controls. Among the nine EBV-related IgA antibody panels, EBNA1-IgA + VCA-IgA [0.928 (0.898, 0.950)], VCA-IgA + Rta-IgG [0.925 (0.890, 0.949)], EBNA1-IgA + VCA-IgA + Zta-IgA [0.962 (0.909, 0.985)] and VCA-IgA + EA-IgA + Rta-IgG [0.945 (0.918, 0.964)] demonstrated higher pooled sensitivity (95%CI). In terms of diagnostic odds ratio (DOR) (95%CI), EBNA1-IgA + VCA-IgA [107.647 (61.173, 189.430)], VCA-IgA + Rta-IgG [105.988 (60.118, 186.857)] and EBNA1-IgA + VCA-IgA + Zta-IgA [344.450 (136.351, 870.153)] showed superior performance. Additionally, the SROC curves for EBNA1-IgA + VCA-IgA and VCA-IgA + Rta-IgG were more favorable. However, publication bias was detected for VCA-IgA (P = 0.005) and EBNA1-IgA + VCA-IgA (P = 0.042)., Conclusions: In general, parallel detection of serum EBNA1-IgA, VCA-IgA and Zta-IgA antibodies using ELISA demonstrates better pooled sensitivity and DOR among the studied panels. In the cases where fewer indicators are used, serum VCA-IgA and EBNA1-IgA/Rta-IgG antibody panel exhibits a comparable performance., Trial Registration: The International Prospective Register of Systematic Reviews registration number: CRD42023426984, registered on May 28, 2023., (© 2024.

Background and Purpose: Early detection, diagnosis, and treatment of colorectal cancer and its precancerous lesions can significantly improve patients' survival rates. The purpose of this research is to identify methylation markers specific to colorectal cancer tissues and validate their diagnostic capability in colorectal cancer and precancerous changes by measuring the level of DNA methylation in stool samples., Method: We analyzed samples from six cancer tissues and adjacent normal tissues and fecal samples from 758 participants, including 62 patients with interfering diseases. Bioinformatics databases were used to screen for candidate biomarkers for CRC, and quantitative methylation-specific PCR methods were applied for identification. The methylation levels of the candidate biomarkers in fecal and tissue samples were measured. Logistic regression and random forest models were built and validated using fecal sample data from one of the centers, and the independent or combined diagnostic value of the candidate biomarkers in fecal samples for CRC and precancerous lesions was analyzed. Finally, the diagnostic capability and stability of the model were validated at another medical center., Results: This study identified two colorectal cancer CpG sites with tissue specificity. These two biomarkers have certain diagnostic power when used individually, but their diagnostic value for colorectal cancer and colorectal adenoma is more significant when they are used in combination., Conclusion: The results indicate that a DNA methylation biomarker combined diagnostic model based on two CpG sites, cg13096260 and cg12587766, has the potential for screening and diagnosing precancerous lesions and colorectal cancer. Additionally, compared to traditional diagnostic models, machine learning algorithms perform better but may yield more false-positive results, necessitating further investigation., (© 2024.

Background: Postoperative recurrence is a vital reason for poor 5-year overall survival in hepatocellular carcinoma (HCC) patients. The ADV score is considered a parameter that can quantify HCC aggressiveness. This study aimed to identify HCC patients at high-risk of recurrence early using the ADV score., Methods: The medical data of consecutive HCC patients undergoing hepatectomy from The First Affiliated Hospital of Nanjing Medical University (TFAHNJMU) and Nanjing Drum Tower Hospital (NJDTH) were retrospectively reviewed. Based on the status of microvascular invasion and the Edmondson-Steiner grade, HCC patients were divided into three groups: low-risk group (group 1: no risk factor exists), medium-risk group (group 2: one risk factor exists), and high-risk group (group 3: coexistence of two risk factors). In the training cohort (TFAHNJMU), the R package nnet was used to establish a multi-categorical unordered logistic regression model based on the ADV score to predict three risk groups. The Welch's T-test was used to compare differences in clinical variables in three predicted risk groups. NJDTH served as an external validation center. At last, the confusion matrix was developed using the R package caret to evaluate the diagnostic performance of the model., Results: 350 and 405 patients from TFAHNJMU and NJDTH were included. HCC patients in different risk groups had significantly different liver function and inflammation levels. Density maps demonstrated that the ADV score could best differentiate between the three risk groups. The probability curve was plotted according to the predicted results of the multi-categorical unordered logistic regression model, and the best cut-off values of the ADV score were as follows: low-risk ≤ 3.4 log, 3.4 log < medium-risk ≤ 5.7 log, and high-risk > 5.7 log. The sensitivities of the ADV score predicting the high-risk group (group 3) were 70.2% (99/141) and 78.8% (63/80) in the training and external validation cohort, respectively., Conclusion: The ADV score might become a valuable marker for screening patients at high-risk of HCC recurrence with a cut-off value of 5.7 log, which might help surgeons, pathologists, and HCC patients make appropriate clinical decisions., (© 2024.

Background: Risk-stratified approaches to breast screening show promise for increasing benefits and reducing harms. But the successful implementation of such an approach will rely on public acceptability. To date, research suggests that while increased screening for women at high risk will be acceptable, any de-intensification of screening for low-risk groups may be met with less enthusiasm. We report findings from a population-based survey of women in England, approaching the age of eligibility for breast screening, to compare the acceptability of current age-based screening with two hypothetical risk-adapted approaches for women at low risk of breast cancer., Methods: An online survey of 1,579 women aged 40-49 with no personal experience of breast cancer or mammography. Participants were recruited via a market research panel, using target quotas for educational attainment and ethnic group, and were randomised to view information about (1) standard NHS age-based screening; (2) a later screening start age for low-risk women; or (3) a longer screening interval for low-risk women. Primary outcomes were cognitive, emotional, and global acceptability. ANOVAs and multiple regression were used to compare acceptability between groups and explore demographic and psychosocial factors associated with acceptability., Results: All three screening approaches were judged to be acceptable on the single-item measure of global acceptability (mean score > 3 on a 5-point scale). Scores for all three measures of acceptability were significantly lower for the risk-adapted scenarios than for age-based screening. There were no differences between the two risk-adapted scenarios. In multivariable analysis, higher breast cancer knowledge was positively associated with cognitive and emotional acceptability of screening approach. Willingness to undergo personal risk assessment was not associated with experimental group., Conclusion: We found no difference in the acceptability of later start age vs. longer screening intervals for women at low risk of breast cancer in a large sample of women who were screening naïve. Although acceptability of both risk-adapted scenarios was lower than for standard age-based screening, overall acceptability was reasonable. The positive associations between knowledge and both cognitive and emotional acceptability suggests clear and reassuring communication about the rationale for de-intensified screening may enhance acceptability., (© 2024.

Background: The spatiotemporal epidemiological evidence supporting joint endoscopic screening for esophageal cancer (EC) and gastric cancer (GC) remains limited. This study aims to identify combined high-risk regions for EC and GC and determine optimal areas for joint and separate endoscopic screening., Methods: We analyzed the association of incidence trends between EC and GC in cancer registry areas across China from 2006 to 2016 using spatiotemporal statistical methods. Based on these analyses, we divided different combined risk regions for EC and GC to implement joint endoscopic screening., Results: From 2006 to 2016, national incidence trends for both EC and GC showed a decline, with an average annual percentage change of -3.15 (95% confidence interval [CI]: -5.33 to -0.92) for EC and -3.78 (95% CI: -4.98 to -2.56) for GC. A grey comprehensive correlation analysis revealed a strong temporal association between the incidence trends of EC and GC, with correlations of 79.00% (95% CI: 77.85 to 80.14) in males and 77.62% (95% CI: 76.50 to 78.73) in females. Geographic patterns of EC and GC varied, demonstrating both homogeneity and heterogeneity across different regions. The cancer registry areas were classified into seven distinct combined risk regions, with 33 areas identified as high-risk for both EC and GC, highlighting these regions as priorities for joint endoscopic screening., Conclusion: This study demonstrates a significant spatiotemporal association between EC and GC. The identified combined risk regions provide a valuable basis for optimizing joint endoscopic screening strategies for these cancers., (© 2024. The Author(s).)

Background: More efficient methods to detect and treat precancerous lesions of the cervix at a single visit, such as low-cost confocal microscopy, could improve early diagnosis and hence outcomes. We piloted a prototype smartphone-compatible confocal micro-endoscope (SCME) among women presenting to a public cervical cancer screening clinic in Kampala, Uganda. We describe the piloting of the SCME device at an urban clinic used by lower cadre staff., Methods: We screened women aged 18 and 60 years, who presented for cervical cancer screening at the Kawempe National Referral Hospital Kampala, and evaluated the experience of their providers (nurses). Nurses received a 2-day training by the study doctors on how to use the SCME, which was added to the standard Visual Inspection with Acetic acid (VIA)-based cervical cancer screening. The SCME was used to take colposcopy images before and after VIA at positions 12 and 6 O'clock if VIA negative, and on precancer-suspicious lesions if VIA positive. We used questionnaires to assess the women's experiences after screening, and the experience of the nurses who operated the SCME., Results: Between November 2021 and July 2022, we screened 291 women with a median age of 36 years and 65.7% were HIV positive. Of the women screened, 146 were eligible for VIA, 123 were screened with the SCME, and we obtained confocal images from 103 women. Of those screened with the SCME, 60% found it comfortable and 81% were willing to screen again with it. Confocal images from 79% of the women showed distinguishable cellular features, while images from the remaining 21% were challenging to analyze. Nurses reported a mean score of 85% regarding the SCME's usefulness to their work, 71% regarding their satisfaction and willingness to use it again, 63% in terms of ease of use, and 57% concerning the ease of learning how to operate the SCME., Conclusion: Our findings demonstrate the feasibility of using the SCME by lower cadre staff in low-resource settings to aid diagnosis of precancerous lesions. However, more work is needed to make it easier for providers to learn how to operate the SCME and capture high-quality confocal images., (© 2024. The Author(s).)

Pancreatic ductal adenocarcinoma (PDAC) is frequently detected in late stages, which leads to limited therapeutic options and a dismal overall survival rate. To date, no robust method for the detection of early-stage PDAC that can be used for targeted screening approaches is available. Liquid biopsy allows the minimally invasive collection of body fluids (typically peripheral blood) and the subsequent analysis of circulating tumor cells or tumor-associated molecules such as nucleic acids, proteins, or metabolites that may be useful for the early diagnosis of PDAC. Single biomarkers may lack sensitivity and/or specificity to reliably detect PDAC, while combinations of these circulating biomarkers in multimarker panels may improve the sensitivity and specificity of blood test-based diagnosis. In this narrative review, we present an overview of different liquid biopsy biomarkers for the early diagnosis of PDAC and discuss the validity of multimarker panels., (© 2024. The Author(s).)

Background: Colorectal cancer (CRC) is the second leading cause of cancer death and the second most common cancer diagnosis among the Hispanic population in the United States. However, CRC screening prevalence remains lower among Hispanic adults than among non-Hispanic white adults. To reduce CRC screening disparities, efforts to implement CRC screening evidence-based interventions in primary care organizations (PCOs) must consider their potential effect on existing screening disparities. More research is needed to understand how to leverage existing implementation science methodologies to improve health disparities. The Coaching to Improve Colorectal Cancer Screening Equity (CoachIQ) pilot study explores whether integrating two implementation science tools, Causal Pathway Diagrams and practice facilitation, is a feasible and effective way to address CRC screening disparities among Hispanic patients., Methods: We used a quasi-experimental, mixed methods design to evaluate feasibility and assess initial signals of effectiveness of the CoachIQ approach. Three PCOs received coaching from CoachIQ practice facilitators over a 12-month period. Three non-equivalent comparison group PCOs received coaching during the same period as participants in a state quality improvement program. We conducted descriptive analyses of screening rates and coaching activities., Results: The CoachIQ practice facilitators discussed equity, facilitated prioritization of QI activities, and reviewed CRC screening disparities during a higher proportion of coaching encounters than the comparison group practice facilitator. While the mean overall CRC screening rate in the comparison PCOs increased from 34 to 41%, the mean CRC screening rate for Hispanic patients did not increase from 30%. In contrast, the mean overall CRC screening rate at the CoachIQ PCOs increased from 41 to 44%, and the mean CRC screening rate for Hispanic patients increased from 35 to 39%., Conclusions: The CoachIQ program merges two implementation science methodologies, practice facilitation and causal pathway diagrams, to help PCOs focus quality improvement efforts on improving CRC screening while also reducing screening disparities. Results from this pilot study demonstrate key differences between CoachIQ facilitation and standard facilitation, and point to the potential of the CoachIQ approach to decrease disparities in CRC screening., (© 2024.

Background: Cervical cancer screening is the primary goal in 90-70-90 targets to reduce cervical cancer incidence and mortality by identifying and treating women with precancerous lesions. Although several studies have been conducted in Sub-Saharan African (SSA) countries on cervical cancer screening, their coverage was limited to the regional or national level, and/or did not address individual- and community-level determinants, with existing evidence gaps to the wider SSA region using the most recent data. Hence, this study aimed to assess the pooled prevalence and multilevel correlates of cervical cancer screening among women with SSA., Methods: This study was conducted using the Demographic Health Survey data (2015-2022) from 11 countries, and a total weighted sample of 124,787 women was considered in the analysis. Using multilevel mixed-effects logistic regression, the influence of each factor on cervical cancer screening uptake was investigated, and significant predictors were reported using the adjusted odds ratio (aOR) with their respective 95% confidence intervals (95% CI)., Results: The overall weighted prevalence of cervical cancer screening was 10.29 (95% CI: 7.77, 11.26), with the highest and lowest screening rates detected in Namibia and Benin at 39.3% (95% CI: 38.05, 40.54) and 0.5% (95% CI: 0.36, 0.69), respectively. Higher cervical screening uptake was observed among women aged 35-49 [aOR = 4.11; 95% CI: 3.69, 4.58] compared to 15-24 years, attending higher education [aOR = 2.71; 95% CI: 2.35, 3.23] than no formal education, being in the richest wealth quintile [aOR = 1.45; 95% CI: 1.26, 1.67], having a recent visit to a health facility [aOR = 1.83; 95% CI: 1.71, 1.95], using contraception [aOR = 1.54; 95% CI: 1.45, 1.64], recent sexual activity [aOR = 3.59; 95% CI: 2.97, 4.34], and listening to the radio [aOR = 1.78; 95%CI: 1.60, 2.15]., Conclusion: The overall prevalence of cervical cancer screening in SSA countries was found to be low; only one in every ten women has been screened. Strengthening universal health coverage, and promoting screening programs with an emphasis on rural areas and low socioeconomic status are key to improving screening rates and equity. Additionally, integrating cervical cancer screening with existing reproductive health programs, e.g. contraceptive service would be important., (© 2024. The Author(s).)

Objectives: In this study, we aimed to validate the performance of the PAX1 and JAM3 methylation (PAX1 m /JAM3 m ) test as a triage tool for detecting cervical intraepithelial neoplasia grade 3 or worse (CIN3 +) in non-16/18 high-risk human papillomavirus-positive patients (non-16/18 hrHPV +)., Methods: The triage performance of liquid-based cytology (LBC) and the PAX1 m /JAM3 m test for detecting CIN3 + were compared., Results: In total, 1851 participants had cervical histological outcomes and were included in the analysis. The sensitivity/specificity of the LBC test results with atypical squamous cells of undetermined significance or worse (LBC ≥ ASCUS) and the PAX1 m /JAM3 m test were 90.1%/26.7% and 84.8%/88.5%, respectively. PAX1 m /JAM3 m ( +) had the highest diagnostic AUC (0.866, 95% confidence interval (CI) 0.837-0.896) in the whole cohort. All cancers (n = 20) were detected by PAX1 m /JAM3 m (+). Compared with LBC ≥ ASCUS, PAX1 m /JAM3 m (+) reduced the number of patients who needed referral for colposcopy by 57.21% (74.66% vs. 17.45%). The odds ratios for detecting CIN3 + by LBC ≥ ASCUS and PAX1 m /JAM3 m (+) were 3.3 (95% CI 2.0-5.9) and 42.6 (27.1-69.6), respectively (p < 0.001). The combination of LBC ≥ ASCUS or PAX1 m /JAM3 m (+) slightly increased the diagnostic sensitivity (98.0%, 95% CI: 95.8-100%) and referral rate (77.09%) but reduced the diagnostic specificity (24.8%, 22.7-26.8%)., Conclusions: In non-16/18 hrHPV(+) women, PAX1 m /JAM3 m was superior to cytology for detecting CIN3 + . Compared with LBC ≥ ASCUS, PAX1 m /JAM3 m (+) reduced the number of significant referrals to colposcopy without compromising diagnostic sensitivity., (© 2024. The Author(s).)

Background: At present, conventional endoscopy and chromoendoscopy using indigo carmine (IC) is a very useful method to determine the demarcation line (DL) of early gastric cancer lesions, but it is not suitable for all lesions., Aims: This study aimed to determine the applicable conditions for IC chromoendoscopy., Methods: We retrospectively evaluated 187 lesions in 181 patients who had an endoscopic diagnosis of EGC and were treated with endoscopic submucosal dissection (ESD). According to the existence of the DL between the lesion mucosa and normal mucosa with IC chromoendoscopy, the lesions were divided into two groups: clear group and unclear group. Clinicopathological characteristics were evaluated in each group. From January 2022 to March 2023, the postoperative pathological sections of 19 lesions (81 slices) in the clear group and 19 lesions (80 slices) in unclear group were scanned with high definition, and the crypt structure between the two groups was evaluated., Results: There was no significant difference in clinical factors between the clear group and unclear group. There were significant differences in crypt area, crypt length, and crypt opening diameter between the two groups. In the clear group, there were significant differences in crypt area, crypt length, and crypt opening diameter between the normal area and cancer area, but there was no significant difference in the unclear group., Conclusions: The margins of lesions with fused or absent crypt structures, a small crypt area, a short crypt length, and a short crypt opening diameter can be easily determined with IC chromoendoscopy., (© 2024.

Background: Breast and cervical cancer are the most common cancers in women, and are associated with high morbidity and mortality rates. Cancer screening can facilitate early diagnosis, reduce mortality, and ease the burden of cancer. Social support and self-efficacy are strongly associated with cancer screening behavior. The present study aimed to explore the mediating effect of self-efficacy on social support and cancer screening behavior., Methods: In this cross-sectional survey study conducted from June to October 2023, 312 women aged 35-65 years were recruited from the East Coast area of China. A general information questionnaire, cancer screening behavior questionnaire, social support scale and self-efficacy scale were used to collect data. Descriptive statistics were used to analyze the general characteristics of participants; one-way analysis of variance was used to test for differences in the measured variables; and Pearson's correlation analyses were used to describe the relationship among social support, self-efficacy, and cancer screening behavior. A mediation model was constructed and analyzed using the PROCESS macro for SPSS., Results: The mean (standard deviation) screening behavior score for breast cancer and cervical cancer was 3.98 (2.79), representing an intermediate level. Self-efficacy was closely related to social support and cancer screening behavior. Social support showed a significant positive correlation with self-efficacy (r = 0.37, p < 0.01) and cancer screening behavior (r = 0.18, p < 0.01). Self-efficacy was also significantly positively correlated with cancer screening behavior (r = 0.19, p < 0.05). Self-efficacy showed a full mediating effect between social support and cancer screening behavior, with an explanatory power of 32%., Conclusions: The findings emphasize the need to increase women's level of social support and self-efficacy, which in turn can increase women's participation in breast and cervical cancer screening., (© 2024.

Introduction: Cancer cases are rising globally, with a noticeable rise in younger adults. Screening and early detection are effective in decreasing mortality. Workplaces can play a role in promoting cancer screening uptake. This systematic review investigated the effectiveness of workplace breast, lung, colorectal, and cervical cancer screening interventions, and the factors impacting their effectiveness., Methodology: Six databases (Embase, Medline, Web of Science, CINAHL, Cochrane Library, Scopus) were searched, and cancer screening promotion and cancer screening uptake was analysed using effect direction plots. Magnitude of effectiveness (i.e., change in knowledge or screening rate) was also evaluated., Results: In total, 13,426 articles were identified. After screening and applying the eligibility criteria, 21 articles were included in the analysis. A positive effect direction was seen for all workplace cancer screening promotion interventions. Magnitude of effectiveness for cancer screening promotion interventions resulted in a > 30% change in knowledge or screening uptake in 4/7 of breast cancer, in 3/4 of cervical cancer and 1/3 colorectal cancer screening promotion interventions. For workplace cancer screening uptake interventions, a positive effect direction was observed for the majority (18/22). Cancer screening uptake interventions showed a > 30% change in magnitude of screening rate in 4/7 breast cancer, 5/10 colorectal cancer and in 1/5 cervical cancer workplace interventions. No studies for lung cancer were eligible. Factors positively influencing effectiveness included an interest in health and previous healthcare use, while fear of cancer and embarrassment of screening negatively influenced effectiveness., Conclusion: Workplace cancer screening promotion and uptake interventions can effectively improve cancer screening knowledge and increase uptake of screening tests., (© 2024.

Background: Cervical cancer remains a significant public health concern in Europe. Effective introduction and scaling up of human papillomavirus (HPV) detection-based cervical cancer screening (CCS) requires a systematic assessment of health systems capacity. However, there is no validated capacity assessment methodology for CCS programmes, especially in European contexts. Addressing this gap, our study introduces an innovative and adaptable protocol for evaluating the capacity of CCS programmes across varying European health system settings., Methods: Our research team developed a three-step capacity assessment framework, incorporating a health policy review checklist, a facility visit survey, and key informants' interview guide followed by a strengths, weaknesses, opportunities and threats (SWOT) analysis. Piloting this comprehensive approach, we explored the CCS capacity in three countries: Estonia, Portugal and Romania. These countries were selected due to their contrasting healthcare structures and resources, providing a diverse overview of the European context., Results: Conducted over a period of 9 months, the capacity assessment covered multiple resources, 27 screening centres, 16 colposcopy and treatment centres and 15 key informant interviews. Our analysis highlighted both shared and country-specific challenges. A key common issue was ensuring high compliance to follow-up and management of screen-positive women. We identified considerable heterogeneity in resources and organization across the three countries, underscoring the need for tailored, rather than one-size-fits-all, solutions., Conclusions: Our study's novelty lies in the successful development of this capacity assessment methodology implementable within a relatively short time frame, proving its feasibility for use in various contexts and countries. The resulting set of materials, adaptable to different cancer types, is a ready-to-use toolkit to improve cancer screening processes and outcomes. This research marks a significant stride towards comprehensive capacity assessment for CCS programmes in Europe. Future directions include deploying these tools in other countries and cancer types, thereby contributing to the global fight against cancer., (© 2024. The Author(s).)

Background: Satisfaction is defined as the perceived fulfillment of patient or client needs and desires through the delivery of healthcare services. In developed countries, more than 60% of women have been screened for cervical cancer. However, only 12% of women in sub-Saharan Africa have been screened for precancerous cervical lesions. There is limited evidence on client satisfaction with cervical cancer screening services (CSCCSS) in Ethiopia, particularly, there is no study conducted by mixed method in the Amhara region., Objective: The study aimed to assess clients' satisfaction with cervical cancer screening services and influencing factors among women screened in Debre Markos town public health facilities in Northwest Ethiopia, 2022/23., Methods: A convergent parallel mixed methods design was conducted in Debre Markos town's public health facilities from October 10th, 2022 to January 10th, 2023. For the quantitative wing, a total of 401 cervical cancer screening service users were selected using a systematic random sampling technique. Data were collected using an interviewer-administered structured questionnaire. Clients were interviewed on exit in a private area far from the screening unit and the data were entered into Epi-data version 4.6.0.2, then exported to STATA version 14 for analysis. A binary logistic regression model was fitted to identify factors associated with client satisfaction with cervical cancer screening services. The qualitative data were collected through in-depth and key informant interviews using a semi-structured topic guide. The data were analyzed using a thematic analysis approach with Open code software (version 4.0.2.3)., Result: The quantitative wing revealed that overall, 65% (95% CI: 60-69) of respondents were satisfied with the cervical cancer screening services they received. Gender of the provider (AOR: 6.11, 95% CI: 3.23-11.55, p-value = 0.000), waiting time (AOR: 4.77, 95% CI: 1.32-17.31, p-value = 0.017), clients' knowledge (AOR: 0.26, 95% CI: 0.12-0.59, p-value = 0.001), and clients' attitude (AOR: 6.43, 95% CI: 3.43-12.03, p-value = 0.000) were significantly associated with CSCCSS., Qualitative Result: The thematic analysis revealed three themes. Theme 1: facility-related barriers (shortage of skilled manpower, shortage of infrastructure, providers' skill gap, unavailability of full service, leadership problem, long waiting time). Theme 2: client-related barriers (poor knowledge and attitude, gender preference). Theme 3: facility-related facilitators (free service, presence of supportive partners)., Conclusion: According to the findings of this study, two-thirds of clients were satisfied with cervical cancer screening services, which was lower than the national target of 80%. Long waiting time, male gender of the service provider, unfavorable attitude, and good knowledge of clients were identified as significant factors negatively affecting client satisfaction with cervical cancer screening., (© 2024.

Background: This study investigated the use of urinary exosomal mRNA as a potential biomarker for the early detection of prostate cancer (PCa)., Methods: Next-generation sequencing was utilized to analyze exosomal RNA from 10 individuals with confirmed PCa and 10 individuals without cancer. Subsequent validation through qRT-PCR in a larger sample of 43 PCa patients and 92 healthy controls revealed distinct mRNA signatures associated with PCa., Results: Notably, mRNAs for RAB5B, WWP1, HIST2H2BF, ZFY, MARK2, PASK, RBM10, and NRSN2 showed promise as diagnostic markers, with AUC values between 0.799 and 0.906 and significance p values. Combining RAB5B and WWP1 in an exoRNA diagnostic model outperformed traditional PSA tests, achieving an AUC of 0.923, 81.4% sensitivity, and 89.1% specificity., Conclusions: These findings highlight the potential of urinary exosomal mRNA profiling, particularly focusing on RAB5B and WWP1, as a valuable strategy for improving the early detection of PCa., (© 2024.

Background: Breast and cervical cancer are major public health issues globally. The reduction in incidence and mortality rates of these cancers is linked to effective prevention, early detection, and appropriate treatment measures. This study aims to analyze the temporal trends in the prevalence of mammography and Papanicolaou test coverage among women living in Brazilian state capitals between 2007 and 2023, and to compare the coverage of these tests before and during the Covid-19 pandemic., Methods: A time series study was conducted using data from the Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey from 2007 to 2023. The variables analyzed included mammography and Papanicolaou test coverage according to education level, age group, race/skin color, regions, and Brazilian capitals. The Prais-Winsten regression model was used to analyze the time series, and Student's t-test was employed to compare the prevalence rates between 2019 and 2023., Results: Between 2007 and 2023, mammography coverage showed a stationary trend (71.1% in 2007 and 73.1% in 2023; p-value = 0.75) with a declining trend observed among women with 12 years or more of education (APC= -0.52% 95%CI -1.01%; -0.02%). Papanicolaou test coverage for all women aged between 25 and 64 exhibited a downward trend from 82% in 2007 to 76.8% in 2023 (APC= -0.45% 95%CI -0.76%; -0.13%). This decline was also noticed among those with 9 years or more of education; in the 25 to 44 age group; among women with white and mixed race; and in the Northeast, Central-West, Southeast, and South regions. When comparing coverage before and during Covid-19 pandemic, a reduction was noted for both tests., Conclusions: Over the years, there has been stability in mammography coverage and a decline in Papanicolaou test. The COVID-19 pandemic negatively impacted the number of these tests carried out among women, highlighting the importance of actions aimed at increasing coverage, especially among the most vulnerable groups., (© 2024.

Background: Colorectal cancer (CRC) ranks as the third most common malignancies in the world, and periodic examination of the patient is advantageous in reducing the mortality of CRC. The first blood-based Septin9 gene methylation assay which recognized by the US FDA for CRC examination was Epi proColon. However, this assay was not broadly applied in the current clinical guideline because of its relatively lower sensitivity in the detection of early-stage CRC., Methods: This study aimed at developing a new multiplex Septin9 methylation assay (ColonUSK) which simultaneously evaluates two CpG-rich subregions in the promoter of the Septin9 gene and an internal control in a single reaction. ColonUSK proved increased sensitivity, with a detection limit as low as 12pg of the positive DNA compared with the Septin9 assay targeting one CpG-rich subregion. 1366 subjects were prospectively recruited from four comprehensive hospitals in China in an opportunistic screening study for assessing its value in CRC detection. Blind testing was developed to evaluate ColonUSK in comparison with clinical examination using clinical gold standard such as colonoscopy., Results: The assay demonstrates clinical sensitivity for diagnosing colorectal cancer (CRC) and advanced adenoma at rates of 77.34% and 25.26%, respectively. Furthermore, ColonUSK exhibits a high degree of specificity for non-CRC cases (95.95%) clinically. Significantly, the detection rate of cases in high-grade intraepithelial neoplasia increased to 54.29%. The value for the assay in the Kappa test was 0.76, showing a high degree of consistency between ColonUSK and clinical gold standard., Conclusions: ColonUSK indicated moderate diagnostic value and could become a non-invasive detection way for CRC. The implementation of the ColonUSK assay has the capacity to markedly enhance CRC screening practices., (© 2024. The Author(s).)

Background: In China, the national cervical cancer screening protocol involves initial testing for high-risk human papillomavirus (hrHPV), followed by cytology for hrHPV-positive cases. This study evaluates the effectiveness of PAX1 methylation (PAX1 m ) analysis in identifying precancerous or cancerous lesions in cervical samples from Chinese women positive for non-16/18 hrHPV strains., Methods: Between February 2022 and March 2023, 281 cervical samples from non-16/18 hrHPV-positive women underwent cytological examination and PAX1 m analysis. The study assessed the statistical relationship between PAX1 m levels and the presence of cervical lesions, comparing the diagnostic performance of PAX1 m to conventional cytology., Results: A significant association was found between PAX1 methylation levels and the risk of CIN2 + and CIN3 + lesions, with 47 instances of CIN2 + detected. Odds ratios (ORs) for moderate and high PAX1 m levels were 8.86 (95% CI: 2.24-42.17) and 166.32 (95% CI: 47.09-784.97), respectively. The area under the ROC curve for PAX1 m in identifying CIN2 + lesions was 0.948 (95% CI: 0.895-0.99). PAX1 m demonstrated similar sensitivity and negative predictive value (NPV) to cytology but reduced the colposcopy referral rate from 47.7% with cytology alone to 25.6% with PAX1 m , showing superior specificity and positive predictive value across age groups., Conclusions: PAX1 methylation is a strong indicator of CIN2 + and CIN3 + risk, offering diagnostic performance comparable to cytology with the added benefit of reduced unnecessary colposcopy referrals. These findings support the use of PAX1 m analysis as a reliable tool for triaging non-16/18 hrHPV-positive women in outpatient settings., (© 2024. The Author(s).)
