RESUMEN
PURPOSE: Our study aimed to develop a relatively accurate gastric cancer (GC) screening score system for urban residents and to validate the screening efficacy. METHODS: The present study included a derivation cohort (n = 3406) and a validation cohort (n = 868) of urban residents. Applying the full-stack engineering intelligent system platform of Hualian Health Big Data of Shandong University, the clinical physical examination data of subjects were collected. Univariate and multivariate analyses were used to identify risk factors for GC, and subsequently, an optimal prediction rule was established to create three distinct scoring systems. RESULTS: In the GC-risk scoring system I, age, plateletocrit (PCT), carcinoembryonic antigen (CEA), glucose, albumin, creatinine were independent risk factors of GC, with scores ranging from 0 to 28 and optimal cut-off was 15.5. The second scoring system consisted of age, PCT, RDW-CV, CEA, glucose, albumin, and creatinine, with scores ranging from 0 to 31. The optimal cut-off point was determined to be 15.5. The scoring system III comprise of age, sex, PCT, RDW CV, CEA, glucose, with scores ranging from 0 to 21 and optimal cut-off was 10.5. All three scoring systems demonstrated excellent discrimination for GC, achieving an AUC of 0.884, 0.89, and 0.876, respectively. In external validation, the AUC values were 0.654, 0.658, and 0.714. Notably, the GC-risk scoring system III exhibited the highest screening efficiency. CONCLUSIONS: Urban residents benefited from the effective and verified GC-risk scoring systems, which demonstrated excellent performance in identifying individuals with an elevated risk of GC.
RESUMEN
OBJECTIVE: This analysis assessed the association between regional income, screening coverage for cervical and breast cancer, and temporal trends in mortality from these cancers in different Brazilian health regions. STUDY DESIGN: Spatiotemporal ecological study across 450 health regions of Brazil. METHODS: Data from 2010 Demographic Census were used to assess income. Variations in income distribution within health regions were measured using the Gini index. Data on screening coverage were obtained from the Ambulatory Information System (SIA/SUS). Mortality was assessed from the Global Burden of Disease Study 2019 data. The average annual percentage change (AAPC) in cervical and breast cancer mortality rates, 2010-2018, was calculated by health regions. Results were presented in regional maps. The associations between income, screening coverage and mortality changes were estimated by bivariate spatial correlation. RESULTS: Health regions located in the South and Southeast regions of Brazil had the greatest percentages of screening coverage and highest per capita incomes with the lowest Gini index values. From 2010 to 2018, mortality rates for cervical cancer were highest in the North and Northeast health regions. Breast cancer mortality rates were highest in the South and Southeast health regions. The AAPC in breast and cervical cancer mortality had a negative association with per capita income and screening coverage, and a positive association with the Gini index. CONCLUSIONS: There are large regional variations in income, screening coverage, and mortality rates for women with breast and cervical cancer. These inequities could be mitigated by policies to address income disparities and improved access to screening.
RESUMEN
Abstract To establish the prevalence of oral mucosal lesions and normal variations in a population of older adults. This observational study was conducted from 2015 to 2016 and involved 156 participants from Los Guido (San José, Costa Rica). The participants' sociodemographic information, risk factors, comorbidity, and clinical examination were evaluated and analyzed descriptively and qualitatively. Findings in oral mucosa were found to preferentially affect women (n=111; 71%) and individuals between the ages of 60 and 69 years (n=65; 42%), having smoking as a risk factor (n=67; 43%), and suffering from arterial hypertension (n=101; 65%). Intraoral findings were mainly presented together with variations from normal and pathology (n=71; 46%), predominantly one variation from normal (n=67; 33%) and one pathology (n=51; 43%). The most prevalent normal variations were the saburral tongue, lingual varicose veins, and cryptic tonsils. Infectious diseases (n=33; 21%), potentially malignant disorders (n=30; 19%), and physical and chemical injuries (n=18; 12%) were the most prevalent groups. The four most predominant lesions were prosthetic stomatitis, actinic cheilitis, frictional keratosis, and atrophic glossitis. The differences in pathological groups were not statistically significant (p=0.392) when comparing the frequency ratio by sex. Variations of the normal anatomy are the predominant ones, the saburral tongue being the most prevalent individually; among the pathologies, the most remarkable group was the infectious diseases, and prosthetic stomatitis was the most frequent. The information about this subject in Costa Rica is limited. So it is important to conduct more studies that contribute to the oral health of the elderly population in this area.
Resumen Establecer la prevalencia de lesiones de la mucosa oral y variaciones de lo normal en una población de adultos mayores. Estudio observacional en 156 participantes de Los Guido (San José, Costa Rica) del 2015 a 2016. Se evaluaron y analizaron de forma descriptiva y cualitativa información sociodemográfica, factores de riesgo, comorbilidad y exploración clínica. Los hallazgos en mucosa oral afectaron preferentemente a las mujeres (n=111; 71%), el rango de edad entre 60 y 69 años (n=65; 42%) y con el tabaco como factor de riesgo (n=67; 43%) e hipertensión arterial (n=101; 65%). Los hallazgos intraorales se presentaron preferentemente de forma conjunta variaciones de lo normal y patologías (n=71; 46%), predominantemente una variación de lo normal (n=67; 33%) y una patología (n=51; 43%). Las variaciones de lo normal más prevalentes fueron lengua saburral, várices linguales y amígdalas criptodónticas. Las enfermedades infecciosas (n=33; 21%), los desórdenes potencialmente malignos (n=30; 19 %) e injurias físicas y químicas (n=18; 12%) fueron los grupos más prevalentes. Las cuatro lesiones más predominantes fueron estomatitis protésica, queilitis actínica, queratosis friccional y glositis atrófica. No hubo diferencia estadísticamente significativa (p=0.392) al comparar la proporción de frecuencia por sexo. Las variaciones de la anatomía normal predominaron; siendo en forma individual la lengua saburral la más frecuente; de las patologías destacaron las enfermedades infecciosas principalmente la estomatitis protésica. Existe poca información en esta área en Costa Rica, es importante generar más estudios que permitan contribuir con la salud oral de la población adulta mayor.
RESUMEN
Infrared thermography is considered a useful technique for diagnosing several skin pathologies but it has not been widely adopted mainly due to its high cost. Here, we investigate the feasibility of using low-cost infrared cameras with microbolometer technology for detecting skin cancer. For this purpose, we collected infrared data from volunteer subjects using a high-cost/high-quality infrared camera. We propose a degradation model to assess the use of lower-cost imagers in such a task. The degradation model was validated by mimicking video acquisition with the low-cost cameras, using data originally captured with a medium-cost camera. The outcome of the proposed model was then compared with the infrared video obtained with actual cameras, achieving an average Pearson correlation coefficient of more than 0.9271. Therefore, the model successfully transfers the behavior of cameras with poorer characteristics to videos acquired with higher-quality cameras. Using the proposed model, we simulated the acquisition of patient data with three different lower-cost cameras, namely, Xenics Gobi-640, Opgal Therm-App, and Seek Thermal CompactPRO. The degraded data were used to evaluate the performance of a skin cancer detection algorithm. The Xenics and Opgal cameras achieved accuracies of 84.33% and 84.20%, respectively, and sensitivities of 83.03% and 83.23%, respectively. These values closely matched those from the non-degraded data, indicating that employing these lower-cost cameras is appropriate for skin cancer detection. The Seek camera achieved an accuracy of 82.13% and a sensitivity of 79.77%. Based on these results, we conclude that this camera is appropriate for less critical applications.

Introduction: Mammography is an excellent resource to reduce the burden of premature death associated with breast cancer; however, screening is only recommended between the ages of 50 and 69 years. General objective: To compare the frequency of suspicious and non-diagnostic mammograms for breast cancer when screening Chilean women between the ages of 40 and 50 years. Patients and methods: Cross-sectional study nested in a breast cancer screening programme in Chilean women >40 years old, conducted between 2017 and 2021. Demographic variables and risk factors are described. To establish the effect of age on screening, we calculated the number needed to screen for a Breast Imaging Reporting and Data Reporting System 4 or 5 mammogram when screening over 40 years or over 50 years. Results: We studied 137,690 women screened for breast cancer since the age of 40 years. The median age was 54 years (range 40-93 years). 64.7% of women were postmenopausal, 4.79% were nulliparous and 14% of post-menopausal women were receiving hormone replacement therapy. To find a suspicious mammogram, 170 women over 40 years and 149 women over 50 years would have to be screened. Conclusion: By changing the starting age of screening from 50 to 40 years 21 more women would have to be screened to detect a suspicious mammogram and if screened from age 50 and not from age 40 years 21% of total suspicious mammograms would remain unidentified.
RESUMEN
Our objective was to determine the prevalence of cervical Pap screening among women living with HIV (WLWH) in Puerto Rico (P.R.) and other selected United States (U.S.) jurisdictions. Additionally, we sought to compare selected characteristics of WLWH who underwent cervical Pap screening between P.R. and the other U.S. jurisdictions. We analyzed data from the 2018-2021 cycles of CDC's Medical Monitoring Project (MMP), a national surveillance system among adults with HIV residing in P.R. (n = 218) and 22 other MMP jurisdictions (n = 3,653). Weighted percentages and 95 % confidence intervals (CIs) for selected characteristics were estimated. Prevalence ratios with predicted marginal means were calculated. An estimated 91.6 % and 84.6 % of WLWH underwent cervical Pap screening in P.R. and the other 22 MMP jurisdictions, respectively (Prevalence Ratio = 1.08, 95% CI = 1.03-1.13). Among WLWH who underwent cervical Pap screening, those in P.R. were more likely to be 50+ years of age, have a household annual income below $20,000, engage in binge drinking, never smoke, and have Medicaid/other public insurance than those in the other 22 MMP jurisdictions (p < 0.05). No differences were found between P.R. and the other 22 MMP jurisdictions in the percentage reporting higher than the median HIV-stigma score, experiencing HIV health care discrimination, and having ≥ 1 sexual partner in the past 12 months. Although cervical Pap screening rates among WLWH were higher in P.R. than in the other 22 MMP jurisdictions, both surpass the Healthy People 2030 target. Future research should assess adherence and compliance with updated cervical cancer screening guidelines.
RESUMEN
OBJECTIVES: Li-Fraumeni syndrome (LFS) is a cancer syndrome associated with early-onset neoplasias. The use of whole-body magnetic resonance imaging (WBMRI) is recommended for regular cancer screening, however, evidence supporting the benefits in asymptomatic LFS patients is limited. This study aims to assess the clinical utility of WBMRI in germline TP53 mutation carriers at baseline and follow-up. MATERIALS AND METHODS: We systematically searched PubMed, Cochrane, and Embase databases for studies evaluating WBMRI as an early detection method for tumor screening in patients with LFS. We pooled the prevalence of the included variables along with their corresponding 95% confidence intervals (CIs). Statistical analyses were performed using R software, version 4.3.1. RESULTS: From 1687 results, 11 comprising 703 patients (359 females (51%); with a median age of 32 years (IQR 1-74)) were included. An estimated detection rate of 31% (95% CI: 0.28, 0.34) for any suspicious lesions was found in asymptomatic TP53 carriers who underwent baseline WBMRI. A total of 277 lesions requiring clinical follow-up were identified in 215 patients. Cancer was confirmed in 46 lesions across 39 individuals. The estimated cancer diagnosis rate among suspicious lesions was 18% (95% CI: 0.13, 0.25). WBMRI detected 41 of the 46 cancers at an early-disease stage, with an overall detection rate of 6% (95% CI: 0.05, 0.08). The incidence rate was 2% per patient round of WBMRI (95% CI: 0.01, 0.04), including baseline and follow-up. CONCLUSION: This meta-analysis provides evidence that surveillance with WBMRI is effective in detecting cancers in asymptomatic patients with LFS. CLINICAL RELEVANCE STATEMENT: Our study demonstrates that whole-body MRI is an effective tool for early cancer detection in asymptomatic Li-Fraumeni Syndrome patients, highlighting its importance in surveillance protocols to improve diagnosis and treatment outcomes. KEY POINTS: Current evidence for whole-body MRI screening of asymptomatic Li-Fraumeni Syndrome (LFS) patients remains scarce. Whole-body MRI identified 41 out of 46 cancers at an early stage, achieving an overall detection rate of 6%. Whole-body MRI surveillance is a valuable method for detecting cancers in asymptomatic LFS patients.
RESUMEN
We have been encouraging practicing gynecologists to adopt molecular diagnostics tests, PCR, and cancer biomarkers, as alternatives enabled by these platforms, to traditional Papanicolaou and colposcopy tests, respectively. An aliquot of liquid-based cytology was used for the molecular test [high-risk HPV types, (HR HPV)], another for the PAP test, and one more for p16/Ki67 dual-stain cytology. A total of 4499 laboratory samples were evaluated, and we found that 25.1% of low-grade samples and 47.9% of high-grade samples after PAP testing had a negative HR HPV-PCR result. In those cases, reported as Pap-negative, 22.1% had a positive HR HPV-PCR result. Dual staining with p16/Ki67 biomarkers in samples was positive for HR HPV, and 31.7% were also positive for these markers. Out of the PCR results that were positive for any of these HR HPV subtypes, n 68.3%, we did not find evidence for the presence of cancerous cells, highlighting the importance of performing dual staining with p16/Ki67 after PCR to avoid unnecessary colposcopies. The encountered challenges are a deep-rooted social reluctance in Mexico to abandon traditional Pap smears and the opinion of many specialists. Therefore, we still believe that colposcopy continues to be a preferred procedure over the dual-staining protocol.

INTRODUCTION AND AIM: Adherence to colorectal cancer (CRC) screening is essential for the effectiveness of screening programs. Even though organized screening programs can improve the quality of the process and adherence, there are still challenges to overcome. The aim of the present study, in which we implemented a biennial organized screening program for CRC, was to describe adherence and participation patterns. MATERIALS AND METHODS: A longitudinal, descriptive study was conducted, in which a team of trained patient navigators carried out interventions, with reminders via cellphone communication, to follow a cohort of 301 subjects eligible for CRC screening, utilizing a fecal immunochemical test (FIT). All the follow-up subjects received a FIT kit. RESULTS: A total of 747 cellphone calls were made and divided into three interventions. From the initial cohort, 126 subjects completed their biennial screening process through the FIT, indicating a consistent adherence rate of 41.8% to our program. The participation patterns were: 126 consistent participants (41.8%), 160 inconsistent participants (53.2%), and 15 participants that were never contacted (5%). CONCLUSIONS: In conclusion, our study underlines the importance of organized screening programs in the early detection of CRC. The implementation of follow-up interventions, through reminders and the training of patient navigators, can improve adherence, but there is a need for examining new strategies, to overcome barriers to communication via cellphone.

BACKGROUND: Despite the effectiveness of colorectal cancer (CRC) screening, American Indians (AIs) have low screening rates in the US. Many AIs receive care at Indian Health Services, Tribal, and Urban Indian (I/T/U) healthcare facilities, where published evidence regarding the implementation of CRC screening interventions is lacking. To address this gap, the University of New Mexico Comprehensive Cancer Center and the Albuquerque Area Southwest Tribal Epidemiology Center collaborated with two tribally-operated healthcare facilities in New Mexico with the goal of improving CRC screening rates among New Mexico's AI communities. METHODS: Guided by the principles of Community Based Participatory Research, we engaged providers from the two tribal healthcare facilities and tribal community members through focus group (two focus groups with providers (n = 15) and four focus group and listening sessions with community members (n = 65)), to elicit perspectives on the feasibility and appropriateness of implementing The Guide to Community Preventive Services (The Community Guide) recommended evidence-based interventions (EBIs) and strategies for increasing CRC screening. Within each tribal healthcare facility, we engaged a Multisector Action Team (MAT) that participated in an implementation survey to document the extent to which their healthcare facilities were implementing EBIs and strategies, and an organizational readiness survey that queried whether their healthcare facilities could implement additional strategies to improve uptake of CRC screening. RESULTS: The Community Guide recommended EBIs and strategies that received the most support as feasible and appropriate from community members included: one-on-one education from providers, reminders, small media, and interventions that reduced structural barriers. From the providers' perspective, feasible and acceptable strategies included one-on-one education, patient and provider reminders, and provider assessment and feedback. Universally, providers mentioned the need for patient navigators who could provide culturally appropriate education about CRC and assist with transportation, and improved support for coordinating clinical follow-up after screening. The readiness survey highlighted overall readiness of the tribal facility, while the implementation survey highlighted that few strategies were being implemented. CONCLUSIONS: Findings from this study contribute to the limited literature around implementation research at tribal healthcare facilities and informed the selection of specific implementation strategies to promote the uptake of CRC screening in AI communities.
RESUMEN
OBJECTIVE: To describe the implementation of an oral cancer screening program at the Barretos Cancer Hospital (BCH) and present the outcome based on data obtained from 2014 to 2020. MATERIALS AND METHODS: The residents of the Regional Health District of Barretos (DRS-V) were personally invited by community health agents or nurses, and among 13,973 people, 15,222 oral examinations were carried out over the years in 18 of its municipalities. Oral examinations were performed at the Mobile Dental Unit and at the Prevention Department of the BCH. Inclusion criteria were being 35 years of age or older, having a personal history of tobacco or alcohol consumption, or having a lesion in the oral cavity found by community health agent or self-reported, regardless of age or risk factors. RESULTS AND CONCLUSION: The main result of our study was the stages of oral cancer among screen detected cases were smaller compared to cases in the hospital registry, in the state and in Brazil. Oral cancer detection rate per 1,000 oral examinations was 10.7.The early stages of oral cancer found by screening in primary care facilities or using mobile units suggest that, when organized, screening may improve the prognosis of oral cancer.

This study aimed to assess the use of colorectal cancer (CRC) tests for prevention and early detection, alongside exploring the associated barriers to these tests. A stratified national survey was conducted in Chile, involving 1893 respondents (with a 2.3% error margin and 95% confidence interval). Logistic and multinomial regression analyses were employed to examine variations in test utilization likelihood and barrier. We found that the key determinants for undergoing CRC tests included age, health status, possession of private health insurance, and attainment of postgraduate education. Notably, 18% and 29% of respondents covered by public and private insurance, respectively, cited personal prevention as the primary motivation for test uptake. The principal obstacle identified was lack of knowledge, mentioned by 65% of respondents, while 29% and 19% of the publicly and privately insured respectively highlighted lack of access as a barrier. The results of this study provide valuable insights into factors influencing CRC screening, aiming to inform public health policies for expanding national coverage beyond diagnosis and treatment to encompass preventive measures.

AIM: Colorectal cancer (CRC) screening rates in the United States remain persistently below guideline targets, partly due to suboptimal patient utilization and provider reimbursement. To guide long-term national utilization estimates and set reasonable screening adherence targets, this study aimed to quantify trends in utilization of and reimbursement for CRC screenings using Medicare claims. METHOD: Inflation-adjusted reimbursements and utilization volume associated with each CRC screening code were abstracted from Medicare claims between 2000 and 2019. Screenings, screenings/100 000 enrolees and reimbursement/screening were analysed with linear regression and compared with the equality of slopes tests. Average reimbursement per screening was compared using analysis of variance with Dunnett's T3 multiple comparisons test. RESULTS: The growth rate of multitarget stool DNA tests (mt-sDNA)/100 000 was the highest at 170.4 screenings/year (R2 = 0.99, p ≤ 0.001), while that of faecal occult blood tests/100 000 was the lowest at -446.4 screenings/year (R2 = 0.90, p ≤ 0.001) (p ≤ 0.001). Provider reimbursements averaged $546.95 (95% CI $520.12-$573.78) per mt-sDNA screening, significantly higher than reimbursements for all invasive screenings. Only FOBTs significantly increased in reimbursement per screening at $0.62/year (R2 = 0.91, p ≤ 0.001). CONCLUSION: We derived forecastable trend numbers for utilization and provider reimbursement. Faecal immunochemical tests/100 000 and mt-sDNA screenings/100 000 increased most rapidly during the entire study period. The number of nearly all invasive screenings/100 000 decreased rapidly; the number of colonoscopies/100 000 increased slightly, probably due to superior diagnostic strength. These trends indicate the that replacement of other invasive modalities with accessible noninvasive screenings will account for much of future screening behaviour and thus reductions in CRC incidence and mortality, especially given providers' reimbursement incentive to screen average-risk patients with stool-based tests.

BACKGROUND: High-risk human papillomavirus (hrHPV) detection in self-collected urine samples (SeCUS) may be a promising alternative for cervical cancer screening because of its greater acceptability, as long as it can offer comparable sensitivity to clinician-collected cervical samples (CCoS) for detecting precancer lesions. OBJECTIVE: To evaluate the performance of the SeCUS compared to that of the CCoS for cervical intraepithelial neoplasia grade 3 (CIN3) detection among hrHPV-positive women receiving colposcopy in Mexico City using different specific extended HPV typing procedures: HPV16/18, HPV16/18/35/39/68 or HPV16/18/35/39/68/31. METHODS: From March 2017 to August 2018, 4,158 female users of the cervical cancer screening program at Tlalpan Sanitary Jurisdiction in Mexico City were invited to participate in the FRIDA-Tlalpan study. All participants provided ≥ 30 mL of SeCUS, and then a CCoS was obtained with Cervex-Brush®, which was used for hrHPV typing. Participants who tested positive for hrHPV in CCoS were referred for colposcopy for diagnostic confirmation, and all SeCUS of these women were also tested for hrHPV typing. RESULTS: In total, 561 hrHPV-positive women were identified by CCoS via colposcopy, and 82.2% of the SeCUS of these women were also hrHPV positive. From both CCoS and SeCUS, 7 cases of CIN3 were detected. Considering HPV16/18 typing, CCoS and SeCUS detected 4 cases of CIN3, but after HPV16/18/35/39/68/31 extension typing, both CCoS and SeCUS detected all 7 of the CIN3 cases among the hrHPV-positive women. CONCLUSIONS: Using extended hrHPV typing based on HPV16/18/35/39/68/31, our results suggest that the performance of SeCUS may be equivalent to that of CCoS for detecting CIN3 lesions. Although our results are inconclusive, they support the hypothesis that SeCUS may be an attractive alternative worthy of further research.

The current study examined cancer prevention and early detection awareness (pre-workshop) and changes in knowledge (from pre- to post-workshop) among Hispanic/Latino (H/L) community members who participated in Spanish-language educational outreach events in Puerto Rico (PR) and Florida (FL). Spanish-language educational outreach events were comprised of an educational session lasting approximately 45-60 min and were delivered to groups in rural and urban community settings by a single trained community health educator (CHE). The research team assessed sociodemographic characteristics, personal and familial cancer health history, as well as awareness and knowledge (pre-test) of a range of cancer prevention and screening topics. Following the presentation, participants completed a post-test knowledge survey which also measured likelihood of engaging in cancer screening, cancer preventive behaviors, and cancer research as a result of information presented during the session. Change in the average knowledge score was evaluated using a paired samples t-test. Post-session likelihood of completing cancer screening and preventive behaviors and engaging in cancer research were examined using descriptive statistics and group/site comparisons. The percentage reporting awareness of screening procedures ranged from 33% (PSA test) to 79% (mammogram). H/L in PR reported higher percentage of stool blood test awareness when compared to H/L in FL (χ2(1)= 19.20, p<.001). The average knowledge score increased from 5.97 at pre-test to 7.09 at post-test (Cohen's d=0.69). The increase was significant across all participants (t(315)= 12.4, p<.001), as well as within the FL site (t(124)= 6.66, p<.001, d=0.59) and the PR site (t(190)=10.66, p<.001, d=0.77). Results from this study suggest that educational outreach events delivered to H/L community members by a CHE are valuable strategies to address challenges regarding cancer screening knowledge and engagement in multiple behaviors.

SUMMARY OBJECTIVE: Obesity is associated with many types of cancers. Despite this, the participation of obese individuals in cancer screenings is limited. The aim of this study was to evaluate the cancer screening-related attitudes of obese patients. METHODS: The study included 185 obese patients who presented to the obesity center (OC) and 191 obese patients who presented to the family medicine outpatient clinic from October to December 2019. The participants in both groups were first asked whether or not they had ever undergone any cancer screening tests and then provided with relevant training. After 3 months, the participants were contacted again and their attitudes toward cancer screening tests were re-evaluated. RESULTS: Patients who followed in the OC were found to have higher awareness of and compliance with cancer screening tests than the obese patients admitted to the outpatient clinic. The factors of being female, being followed in the OC, and residing in an urban area were positively associated with participation in cancer screening tests. CONCLUSION: Monitoring obese patients in target-oriented facilities such as an OC increases the chance of success in the fight against obesity and related health problems.
RESUMEN
Cancer is a major public health problem in South America. The cancer mortality burden is increasing in the region due to its presentation at later stages, which is related to limited access to cancer care. This results in a noticeable inequity in provisions of cancer care including specialized screening programs, as well as cancer-related treatments such as personalized medicine, radiation therapy, palliative care, and survivorship services. Consequently, South America faces many challenges for cancer control, most of them deriving from a lack of funding and unequal distribution of resources and cancer services, affecting mostly the underserved populations in the region.

OBJECTIVE: Deep learning (DL) has shown promising results for improving mammographic breast cancer diagnosis. However, the impact of artificial intelligence (AI) on the breast cancer screening process has not yet been fully elucidated in terms of potential workload reduction. We aim to assess if AI-based triaging of breast cancer screening mammograms could reduce the radiologist's workload with non-inferior sensitivity. METHODS: PubMed, EMBASE, Cochrane Central, and Web of Science databases were systematically searched for studies that evaluated AI algorithms on computer-aided triage of breast cancer screening mammograms. We extracted data from homogenous studies and performed a proportion meta-analysis with a random-effects model to examine the radiologist's workload reduction (proportion of low-risk mammograms that could be theoretically ruled out from human's assessment) and the software's sensitivity to breast cancer detection. RESULTS: Thirteen studies were selected for full review, and three studies that used the same commercially available DL algorithm were included in the meta-analysis. In the 156,852 examinations included, the threshold of 7 was identified as optimal. With these parameters, radiologist workload decreased by 68.3% (95%CI 0.655-0.711, I² = 98.76%, p < 0.001), while achieving a sensitivity of 93.1% (95%CI 0.882-0.979, I² = 83.86%, p = 0.002) and a specificity of 68.7% (95% CI 0.684-0.723, I² = 97.5%, p < 0.01). CONCLUSIONS: The deployment of DL computer-aided triage of breast cancer screening mammograms reduces the radiology workload while maintaining high sensitivity. Although the implementation of AI remains complex and heterogeneous, it is a promising tool to optimize healthcare resources.

OBJECTIVE: There are an estimated 5,570 yearly cancer deaths in Puerto Rico. Breast and colorectal are the most common malignancies among Puerto Rican women. Therefore, prevention and early detection of these cancer types are critical to reducing morbidity and mortality. This study assessed whether women who received the influenza vaccine had increased adherence to cervical, breast, and colorectal cancer screening. METHODS: The Puerto Rico Community Engagement Alliance (PR-CEAL) against COVID-19 Disparities team attended community outreach events throughout Puerto Rico and completed a face-to-face survey among women 18 years or older. The survey gathered demographic information and adherence to influenza vaccination and cervical, breast, and colorectal screening in the past year. The initial sample included 400 women, of whom 347 met the age inclusion criteria (21-74 years). Chi-square tests were used to compare cancer screening adherence according to influenza vaccination status. A p-value <0.05 was considered statistically significant. RESULTS: Of all participants, 47.0% received the influenza vaccine in the past year. Cancer screening rates among vaccinated and non-vaccinated women were as follows: 64.5% vs. and 13.0% vs. 8.0% for colorectal cancer (p-value=0.19). CONCLUSION: Adherence to cervical, breast, and colorectal cancer screening in the past year did not differ by influenza vaccination status. Influenza vaccination appointments may therefore represent a missed opportunity to promote preventative cancer screening in Puerto Rico.

Puerto Rico (PR) has faced environmental and public health challenges that could have significantly affected cancer screening access. Using administrative claims data from PR's Medicaid population, this study assessed trends in colorectal and breast cancer screening from 2016 to 2021, the impact of disasters in screening, and the absolute deficit in screening due to the pandemic. The monthly rates of claims were analyzed using Poisson regression. Significant reductions in breast and colorectal cancer screening utilization were observed. The colorectal cancer screening rate in 2017 was 77% lower a month after Hurricanes Irma and María [RRadj: 0.23; 95% CI: 0.20, 0.25] compared to the same time period in 2016. Breast cancer screening dropped 50% in November 2017 compared to November 2016 [RRadj: 0.50; 95% CI: 0.47, 0.54]. Prospectively, a recovery in utilization has been observed only for breast cancer screening. The results revealed that cancer screening utilization substantially declined after environmental disasters and the pandemic. These findings have potentially severe long-term implications for cancer health disparities and mortality in PR.
