Intervención educativa para perfeccionar la ejecución del Programa de Detección Precoz del Cáncer Bucal

Introducción: las lesiones premalignas y malignas del complejo bucal se incrementan en la población, lo que demanda una correcta ejecución del Programa de Detección Precoz del Cáncer Bucal (PDCB). En el trabajo se exponen las transformaciones en el nivel de conocimientos de pacientes y estomatólogos acerca de las afecciones concernientes al PDCB para perfeccionar su ejecución. Método: se realizó una intervención educativa en el área de salud Julio Antonio Mella del municipio Camagüey desde mayo de 2022 hasta junio de 2023, con la participación de 36 pacientes y 30 estomatólogos. Las fuentes de información fueron la historia clínica, un cuestionario y una prueba de entrada y salida, aplicados a pacientes y estomatólogos respectivamente, antes y después de la intervención; para constatar las transformaciones. Resultados: antes de la intervención los pacientes estaban mal informados sobre las consecuencias nocivas de hábitos tóxicos, higiénicos y dietéticos, así como desconocimiento de la importancia del correcto autoexamen bucal; los que alcanzaron en su mayoría un alto nivel de conocimientos con la intervención. Los estomatólogos mejoraron sus conocimientos sobre diagnóstico y seguimiento de lesiones pre malignas y malignas del complejo maxilofacial. Discusión: la adecuada ejecución del PDCB descansa tanto en pacientes como en estomatólogos y aunque las investigaciones se enfocan a los primeros por los beneficios reportados; la superación de posgrado constituye una vía para sistematizar conocimientos y fortalecer competencias profesionales que impacten de manera positiva en el PDCB. La intervención educativa se considera satisfactoria al elevar el nivel de conocimientos de pacientes y estomatólogos, lo que demuestra sus potencialidades para perfeccionar la ejecución del PDCB.

Introduction: premalignant and malignant lesions of de oral area increase in the population which demands a correct implementation of the Early Detection of Oral Cancer Program. In this work transformations are exposed knowledge level of both patients and dentists regarding lesions concerning the Early Detection of Oral Cancer Program (EDOCP). Method: educational intervention was carried out in Julio Antonio Mella health area of Camaguey municipality from May 2022 to June 2023 which 36 patients and 30 Deontologists. Information sources were the Clinical History, a questionnaire and a test applied to patients and Deontologists respectively, before and after the intervention, to confirm the transformations in the sample. Results: Prior to intervention patients were poorly informed about consequences of toxic, hygienic and dietetic habits combined with lack of knowledge regarding importance of a correct oral self-examination whose knowledge improved to reach a high level in most of them after the intervention. Deontologists improved their knowledge on diagnosis and follow-up of premalignant and malignant lesions affecting the maxillofacial complex. Discussion: correct application of the EDOCP depends on both patients and deontologists, however reserchers focus on the former due to the reported benefits; the postgraduate training is a way to systematize knowledge and strengthen professional competences with positive impact on EDOCP. The educational intervention was satisfactory since it improved the level of knowledge of both patients and dentists which shows its potential on a correct implementation of the Early Detection of Oral Cancer Program.

Concordancia inter- e intraobservador del puntaje PI-RADS 2.1 del Colegio Americano de Radiología / Intraobserver and interobserver agreement of the American College of Radiology PI-RADS 2.1 score

Resumen Antecedentes: La resonancia magnética (RM) de próstata es uno de los métodos diagnósticos para la identificación del carcinoma de próstata. La escala PI-RADS (Prostate Imaging and Reporting Data System) es el sistema usado para la interpretación de estas imágenes. Es importante, para su reproducibilidad, la estandarización y la evaluación de dicha escala. Objetivo: Determinar la concordancia inter- e intraobservador de la versión 2.1 del PI-RADS. Material y métodos: Estudio observacional retrospectivo, evaluando 129 RM de pacientes con sospecha de cáncer de próstata por tres radiólogos con diferentes años de experiencia y en dos momentos del tiempo, usando el puntaje PI-RADS 2.1. Se evaluó la concordancia intra- e interobservador. Resultados: La concordancia interobservador fue sustancial (kappa > 0,6) en todos los observadores, siendo la categoría 5 la de mayor acuerdo interobservador. Se observó una alta reproducibilidad intraobservardor, con la mayor kappa siendo de 0,856. Cuando se realizó el análisis según años de experiencia de los radiólogos, la concordancia interobservador fue significativa en todos los casos. Conclusiones: El sistema de clasificación PI-RADS 2.1 es reproducible para las diferentes categorías y aumenta la concordancia cuando se trata de lesiones con mayor probabilidad de cáncer clínicamente significativo.

Abstract Background: Magnetic Resonance Imaging (MRI) of the prostate is a key diagnostic tool for identifying prostate carcinoma. The Prostate Imaging-Reporting and Data System (PI-RADS) scale is the standard system for interpreting these images. Standardizing and evaluating this scale is crucial for ensuring consistent and reproducible results. Objective: This study aims to assess both the interobserver and intraobserver agreement of the PI-RADS version 2.1. Material and methods: In this retrospective observational study, 129 prostate MRI scans from patients with suspected prostate cancer were evaluated. Three radiologists, each with different levels of experience, analyzed these scans at two separate times using the PI-RADS 2.1 scoring system. Both intraobserver and interobserver agreements were measured. Results: The study found substantial interobserver agreement (kappa > 0.6) across all categories, with category 5 showing the highest level of agreement. Intraobserver reproducibility was also high, with the highest kappa value reaching 0.856. Further analysis based on the radiologists’ years of experience revealed significant interobserver agreement in all instances. Conclusions: The PI-RADS 2.1 classification system demonstrates high reproducibility across different categories, particularly for lesions more likely to be clinically significant cancers. This underscores its reliability in varied diagnostic scenarios.

Developing a breast cancer screening decision aid in Spanish for average-risk women: a mixed methods study / Desarrollo de una herramienta en español para ayudar en la toma de decisiones del cribado de cáncer de mama para mujeres de riesgo promedio: un estudio de métodos mixtos

INTRODUCTION: We aimed to develop a decision aid to support shared-decision making between physicians and women with average breast cancer risk when deciding whether to participate in breast cancer screening. METHODS: We included women at average risk of breast cancer and physicians involved in supporting the decision of breast cancer screening from an Academic Hospital in Buenos Aires, Argentina. We followed the International Patient Decision Aid Standards to develop our decision aid. Guided by a steering group and a multidisciplinary consultancy group including a patient advocate, we reviewed the evidence about breast cancer screening and previous decision aids, explored the patients' information needs on this topic from the patients' and physicians' perspective using semi-structured interviews, and we alpha-tested the prototype to determine its usability, comprehensibility and applicability. RESULTS: We developed the first prototype of a web-based decision aid to use during the clinical encounter with women aged 40 to 69 with average breast cancer risk. After a meeting with our consultancy group, we developed a second prototype that underwent alpha-testing. Physicians and patients agreed that the tool was clear, useful and applicable during a clinical encounter. We refined our final prototype according to their feedback. CONCLUSION: We developed the first decision aid in our region and language on this topic, developed with end-users' input and informed by the best available evidence. We expect this decision aid to help women and physicians make shared decisions during the clinical encounter when talking about breast cancer screening.

RESUMEN Objetivo: evaluar la sensibilidad y especificidad del test G8 en el tamizaje de adultos mayores con cáncer para la realización de la valoración geriátrica integral (VGI). Materiales y métodos: el presente estudio observacional y retrospectivo se realizó en el Servicio de Geriatría del Hospital Almenara de Lima, Perú. Se revisaron los informes de VGI en las historias clínicas electrónicos de adultos mayores (> 60 años) con cáncer, ambulatorios y hospitalizados, durante noviembre de 2022 y julio de 2023. Los pacientes se clasificaron según los criterios SIOG-1 (Sociedad Internacional de Oncología Geriátrica), formando dos grupos: pacientes aptos y pacientes no aptos o unfit (vulnerables + frágiles + muy enfermos). Del test G8 se estimó la sensibilidad, especificidad y valor predictivo positivo, área bajo la curva característica operativa del receptor (AUC). Resultados: ingresaron al estudio 201 pacientes, 91 mujeres (45,3%) y 110 (54,7%) varones, la media de la edad fue de 76,2 ± 7,4 años. Las neoplasias más frecuentes fueron colorrectal, estómago, próstata y vías biliares. La prevalencia de pacientes aptos y no aptos (unfit) fue del 23,4 y 76,6%, respectivamente. Cuando el puntaje de la prueba G8 fue ≤11, la sensibilidad, especificidad, valor predictivo positivo y AUC fueron 73,4% (intervalo de confianza al 95%: 65,7-80,2%), 91,5% (79,6%-97,6%), 96,6% (91,7-98,6%) y 89% (84-93%), respectivamente. Conclusiones: el test G8 con puntaje ≤11 tendría una alta sensibilidad y especificidad, para identificar adultos con cáncer vulnerables o frágiles, que podrían beneficiarse de la VGI.

ABSTRACT Objective: To evaluate sensitivity and specificity of the G8 test in screening older adults with cancer who may benefit from a Comprehensive Geriatric Assessment (CGA). Material and methods: This observational retrospective study was carried out in the Geriatrics Service of the Guillermo Almenara Hospital in Lima, Peru. CGA reports were reviewed in the electronic medical records of older adults (> 60 years) with cancer, both outpatients and inpatients, between November 2022 and July 2023. Patients were classified according to the SIOG-1 (International Society of Geriatric Oncology) criteria into two groups: fit and non-fit patients (vulnerable + frail + too sick). Sensitivity, specificity, and positive predictive value, area under the receiver operating characteristic curve (AUC), were estimated for the G8 test. Results: 201 patients entered the study, 91 women (45.3%) and 110 (54.7%) men; their mean age was 76.2 ± 7.4 years. The most frequent neoplasms were colorectal, stomach, prostate, and bile ducts. The prevalence of eligible and unfit patients was 23.4% and 76.6%, respectively. When the G8 test score was ≤11, sensitivity, specificity, positive predictive value, and AUC were 73.4% (95% Confidence Interval: 65.7- 80.2%), 91.5% (79.6%-97.6%), 96.6% (91.7-98.6%), and 89% (84-93%), respectively. Conclusions: The G8 test with a score ≤11 would have high sensitivity and specificity for identifying vulnerable or frail patients with cancer who could benefit from the CGA.

Impact of Mobile Application Intervention: DETAK in Early Detection and Early Treatment of Acute Coronary Syndrome

@#Introduction: Acute Coronary Syndrome (ACS) is still a major cause of mortality and morbidity globally. One of the factors that cause a prehospital delay is the delay in early detection and inaccuracy of early treatment of ACS. The Internet of Things, which is supported by the high use of smartphones with the DETAK application, can be an opportunity to facilitate ACS education programs so that ACS can be detected early. Method: This study has used a quantitative research design with a quasi-experimental approach which pretest and posttest, in which both the experimental and control groups participate. The inclusion criteria of this study were age >45 years; obesity; smoker; Respondents with a history of: hypertension/diabetes mellitus/hyperlipidemia/hypercholesterolemia/CVD/families with cardiovascular disease. 252 respondents who met the inclusion criteria were randomly divided into control (n=126) and intervention groups (n=126). The intervention group was given education through the DETAK application and the control group was given leaflet about ACS. Results: The results of the study showed that there was an increased in early treatment ability was only found in the intervention group (p<.001). Mean differences of the ability of early detection (p<.001) and early treatment (p=.019)between intervention and control groups were both significance. Conclusion: There is potential for DETAK applications to improve the early detection and treatment capabilities of ACS.

Expert consensus on the molecular diagnosis of early-stage pancreatic cancer （2023 edition） / 临床肝胆病杂志

Pancreatic cancer is a relatively common tumor of the digestive system， with difficulties in early-stage diagnosis and an extremely high degree of malignancy. Molecular diagnostic technology based on tumor biomarkers， combined with the existing gold standard in clinical practice， is of great clinical significance to achieve early accurate identification， timely treatment and intervention， and reduction in mortality. Previous studies have shown that miRNAs show high specificity in terms of types and expression levels in different pathological stages of pancreatic cancer and can thus be used in monitoring the development and progression of pancreatic cancer. Since a single miRNA has a limited diagnostic potential， the combination of different miRNAs may effectively improve the diagnostic efficiency of early-stage pancreas carcinogenesis. Based on related research advances in recent years， this consensus document aims to fill the gap in molecular diagnostic technology in the guidelines for the clinical diagnosis and treatment of pancreatic cancer and provide expert guidance and recommendations.

Adequação da oferta de procedimentos para a detecção precoce do câncer de mama no Sistema Único de Saúde: um estudo transversal, Brasil e regiões, 2019 / Adequacy of provision of procedures for early detection of breast cancer in the Brazilian Unified National Health System: a cross-sectional study conducted in Brazil and its regions, 2019 / Adecuación de la oferta de procedimientos para la detección precoz del cáncer de mama en el Sistema Único de Salud: un estudio transversal, Brasil y regiones, 2019

Resumo: A detecção precoce é uma das estratégias para o controle do câncer de mama e, para tanto, é fundamental garantir o acesso à investigação dos casos suspeitos para continuidade do cuidado e tratamento oportuno. Este estudo tem por objetivo estimar a necessidade de procedimentos para detecção precoce dessa neoplasia e avaliar a sua adequação no atendimento às mulheres rastreadas e sintomáticas no Sistema Único de Saúde (SUS), no ano de 2019. Foi realizado um estudo descritivo transversal para analisar a oferta de exames de detecção precoce do câncer de mama, comparando a necessidade estimada com os procedimentos realizados no SUS. Foram utilizados os parâmetros disponibilizados pelo Instituto Nacional de Câncer para estimar a população e a necessidade de exames para a detecção precoce. No Sistema de Informações Ambulatoriais do SUS, obteve-se o número de procedimentos realizados em 2019. Observou-se um déficit de mamografias de rastreamento no país (-45,1%), variando entre -31,4% na Região Sul a -70,5% na Região Norte. Se a oferta desse exame fosse direcionada para a população-alvo do rastreamento, o déficit no país reduziria para -14,8% e haveria sobreoferta no Sul (6,2%). Os procedimentos de investigação diagnóstica apresentaram variações entre as regiões, com maiores déficits de punção por agulha grossa (-90,8%) e biópsia/exérese de nódulo da mama (-80,6%) observados no Centro-oeste, e o maior déficit de exames anatomopatológicos no Norte (-88,5%). A comparação entre a produção e a necessidade de procedimentos para detecção precoce do câncer de mama no Brasil identificou déficits e inadequações que devem ser melhor conhecidos e equacionados em nível estadual e municipal.

Abstract: Early detection is a major strategy in breast cancer control and, for this reason, it is important to ensure access to investigation of suspected cases for care continuity and timely treatment. This study aimed to estimate the need for procedures of breast cancer early detection and assess their adequacy for providing care to screened and symptomatic women in the Brazilian Unified National Health System (SUS) in 2019. A descriptive cross-sectional study was conducted to analyze the provision of tests for breast cancer early detection, comparing the estimated need with the procedures performed in the SUS. Parameters provided by the Brazilian National Cancer Institute were used to estimate the population and the need for early detection tests. The number of procedures performed in 2019 was obtained from the Outpatient Information System of the SUS. A deficit in screening mammograms was observed in the country (-45.1%), ranging from -31.4% in the South Region to -70.5 % in the North Region. If this test was offered to the target population, the deficit in the country would reduce to -14.8% and there would be an oversupply in the South Region (6.2%). Diagnostic investigation procedures varied between the regions, with higher deficits in coarse needle biopsy (-90.8%) and breast lump biopsy/excision (-80.6%) observed in the Central-West Region, and the highest deficit in anatomopathological exams in the North Region (-88.5%). The comparison between the production and need for procedures of breast cancer early detection in Brazil and its regions identified deficits and inadequacies that must be better understood and addressed at the state and municipal levels.

Resumen: La detección temprana es una de las estrategias para el control del cáncer de mama y, para ello, es fundamental garantizar el acceso a la investigación de los casos sospechosos para la continuidad del cuidado y el tratamiento oportuno. El presente estudio tiene como objetivo estimar la necesidad de procedimientos para la detección temprana de esta neoplasia y evaluar su adecuación en la atención a las mujeres rastreadas y sintomáticas en el Sistema Único de Salud (SUS) brasileño, en el año 2019. Se realizó un estudio descriptivo transversal para analizar la oferta de pruebas para la detección temprana del cáncer de mama, comparando la necesidad estimada con los procedimientos realizados en el SUS. Se utilizaron los parámetros proporcionados por el Instituto Nacional del Cáncer para estimar la población y la necesidad de pruebas para la detección temprana. El número de procedimientos realizados en el 2019 se obtuvo del Sistema de Información Ambulatoria del SUS. Se observó un déficit de mamografías de tamizaje en el país (-45,1%), oscilando entre el -31,4% en la Región Sur y el -70,5% en la Región Norte. Si la oferta de esta prueba se dirigiera a la población objetivo del rastreo, el déficit en el país se reduciría al -14,8% y habría una sobreoferta en el Sur (6,2%). Los procedimientos de investigación diagnóstica presentaron variaciones entre regiones, observándose mayores déficits en punción con aguja gruesa (-90,8%) y biopsia/escisión de nódulo mamario (-80,6%) en el Centro-Oeste, y el mayor déficit de pruebas anatomopatológicas en el Norte (-88,5%). La comparación entre la producción y la necesidad de procedimientos para la detección temprana del cáncer de mama en Brasil y en las regiones identificó déficits e insuficiencias que deben ser mejor conocidos y abordados a nivel estatal y municipal.

Analysis of the indications for and results of breast cancer screening by magnetic resonance imaging at a cancer center in Brazil / Análise das indicações e resultados da ressonância magnética para rastreamento de câncer de mama em um centro oncológico brasileiro

Abstract Objective: To evaluate the indications for and results of magnetic resonance imaging (MRI) examinations for breast cancer screening at a cancer center in Brazil. Materials and Methods: This was a retrospective observational study, based on electronic medical records, of patients undergoing MRI for breast cancer screening at a cancer center in Brazil. Results: We included 597 patients between 19 and 82 years of age. The main indications for MRI screening were a personal history of breast cancer, in 354 patients (59.3%), a family history of breast cancer, in 102 (17.1%), and a confirmed genetic mutation, in 67 (11.2%). The MRI result was classified, in accordance with the categories defined in the Breast Imaging Reporting and Data System, as benign (category 1 or 2), in 425 patients (71.2%), probably benign (category 3), in 143 (24.0%), or suspicious (category 4 or 5), in 29 (4.9%). On MRI, 11 malignant tumors were identified, all of which were invasive carcinomas. Among those 11 carcinomas, six (54.5%) were categorized as minimal cancers (< 1 cm), and the axillary lymph nodes were negative in 10 (90.9%). The cancer detection rate was 18.4/1,000 examinations, and the positive predictive value for suspicious lesions submitted to biopsy was 37.9%. Conclusion: In our sample, the main indication for breast MRI screening was a personal history of breast cancer. The results indicate that MRI is a highly accurate method for the early detection of breast neoplasms in this population.

Foram identificados 11 tumores malignos na RM, todos carcinomas invasivos, porcentagem de cânceres "mínimos" (< 1 cm) de 54,5% e porcentagem de axila negativa de 90,9%. A taxa de detecção de câncer na RM foi 18,4/1000 exames e o valor preditivo positivo para as lesões suspeitas submetidas a biópsia foi 37,9%. Conclusão: A principal indicação para RM de rastreamento na nossa população foi história pessoal de câncer de mama. Os resultados mostraram que a RM constitui um método com alta acurácia para detecção precoce de neoplasias da mama nessa população.

Lung cancer screening in Brazil: recommendations from the Brazilian Society of Thoracic Surgery, Brazilian Thoracic Association, and Brazilian College of Radiology and Diagnostic Imaging / Recomendações da Sociedade Brasileira de Cirurgia Torácica, Sociedade Brasileira de Pneumologia e Tisiologia e Colégio Brasileiro de Radiologia e Diagnóstico por Imagem para o rastreamento do câncer de pulmão no Brasil

ABSTRACT Although lung cancer (LC) is one of the most common and lethal tumors, only 15% of patients are diagnosed at an early stage. Smoking is still responsible for more than 85% of cases. Lung cancer screening (LCS) with low-dose CT (LDCT) reduces LC-related mortality by 20%, and that reduction reaches 38% when LCS by LDCT is combined with smoking cessation. In the last decade, a number of countries have adopted population-based LCS as a public health recommendation. Albeit still incipient, discussion on this topic in Brazil is becoming increasingly broad and necessary. With the aim of increasing knowledge and stimulating debate on LCS, the Brazilian Society of Thoracic Surgery, the Brazilian Thoracic Association, and the Brazilian College of Radiology and Diagnostic Imaging convened a panel of experts to prepare recommendations for LCS in Brazil. The recommendations presented here were based on a narrative review of the literature, with an emphasis on large population-based studies, systematic reviews, and the recommendations of international guidelines, and were developed after extensive discussion by the panel of experts. The following topics were reviewed: reasons for screening; general considerations about smoking; epidemiology of LC; eligibility criteria; incidental findings; granulomatous lesions; probabilistic models; minimum requirements for LDCT; volumetric acquisition; risks of screening; minimum structure and role of the multidisciplinary team; practice according to the Lung CT Screening Reporting and Data System; costs versus benefits of screening; and future perspectives for LCS.

RESUMO O câncer de pulmão (CP) é uma das neoplasias mais comuns e letais no Brasil, e apenas 15% dos pacientes são diagnosticados nos estágios iniciais. O tabagismo persiste como o responsável por mais de 85% de todos os casos. O rastreamento do CP (RCP) por meio da TC de baixa dosagem de radiação (TCBD) reduz a mortalidade do CP em 20%, e, quando combinado com a cessação do tabagismo, essa redução chega a 38%. Na última década, diversos países adotaram o RCP como recomendação de saúde populacional. No Brasil, embora ainda incipiente, a discussão sobre o tema é cada vez mais ampla e necessária. Com o intuito de aumentar o conhecimento e estimular o debate sobre o RCP, a Sociedade Brasileira de Cirurgia Torácica, a Sociedade Brasileira de Pneumologia e Tisiologia e o Colégio Brasileiro de Radiologia e Diagnóstico por Imagem constituíram um painel de especialistas para elaborar as recomendações para o RCP. As recomendações aqui apresentadas foram baseadas em revisão narrativa da literatura, com ênfase em grandes estudos populacionais, em revisões sistemáticas e em recomendações de diretrizes internacionais, sendo construídas após ampla discussão pelo grupo de especialistas. Os temas revisados foram os seguintes: porque rastrear, considerações gerais sobre tabagismo, epidemiologia do CP, critérios de elegibilidade, achados incidentais, lesões granulomatosas, modelos probabilísticos, requisitos mínimos da TCBD, aquisições volumétricas, riscos do rastreamento, estrutura mínima e papel da equipe multidisciplinar, conduta segundo o Lung CT Screening Reporting and Data System (Lung-RADS), custos vs. benefícios e perspectivas do rastreamento.

Estrategias para mejorar la tasa de detección de adenomas y pólipos serrados durante una colonoscopia / Strategies to improve the detection rate of adenomas and serrated polyps during a colonoscopy

Adenoma detection rate (ADR) is a key quality indicator in screening colonoscopy, closely linked to colorectal cancer (CRC) prevention. Currently, the minimum recommended ADR is > 30% with an aspirational goal of > 35%; and the sessile serrated lesion detection rate (SSLDR) minimum is > 7% with an aspirational goal of > 10%. Improving the detection of adenomas and serrated lesions involves rigorous bowel preparation, using the validated Boston Bowel Preparation Scale (BBPS) with an adequate or superior score (≥ 6, with each segment ≥ 2: right-transverse-left) (minimum > 90% and > 95% aspirational goal). The most basic strategy is to implement split-dose bowel preparation regimens. A minimum withdrawal time of 6 minutes, ideally extended to 9 minutes, improves ADR and SSLDR, especially in the proximal colon. Incorporating techniques such as double examination of the right colon (retroflexion or second forward view), water-assisted colonoscopy, enhanced imaging endoscopy technologies (e.g., NBI, TXI, LCI, BLI), distal attachment devices, artificial intelligence systems (CADe), along with monitoring, feedback, continuing education, and teamwork, are key strategies to increase ADR and SSLDR, consequently, reduce the risk of post-colonoscopy or interval CRC.

La tasa de detección de adenomas (ADR) es un indicador de calidad fundamental en la colonoscopia de tamizaje, estrechamente relacionado con la prevención del cáncer colorrectal (CCR). Actualmente la ADR mínima reco- mendada es > 30% y aspiracional > 35%; y la tasa de detección de lesiones serradas sésiles (SSLDR) mínima > 7% y aspiracional > 10%. Mejorar la detección de adenomas y pólipos serrados implica una preparación intestinal rigurosa, utilizando la escala validada de Boston con puntuación adecuada o superior (≥ 6, con cada segmento ≥ 2: derecho-transverso-izquierdo) (mínimo > 90% y > 95% meta aspiracional). Siendo la estrategia más básica implementar regímenes de preparación intestinal en dosis divididas. Un tiempo de retirada mínimo de 6 minutos, idealmente extendido a 9 minutos, mejora la ADR y SSLDR, especialmente en el colon proximal. La incorporación de técnicas como la doble inspección del colon derecho (retroflexión o segunda visión frontal), la colonoscopia asistida por agua, tecnologías de endoscopia con imagen mejorada (ej: NBI, TXI, LCI, BLI), dispositivos de fija- ción distal, sistemas de inteligencia artificial (CADe), junto con la monitorización, retroalimentación, educación continua y trabajo en equipo, son estrategias clave para aumentar la ADR y SSLDR, en consecuencia, reducir el riesgo de CCR posterior de colonoscopia o intervalo.

Investigating under-reported human papillomavirus genotypes in Grenadian women through self-sampling for cervical cancer screening / Investigación de los genotipos de virus del papiloma humano infranotificados en mujeres de Granada mediante automuestreo para el tamizaje del cáncer cervicouterino / Investigação de genótipos subnotificados de papilomavírus humano em mulheres de Granada por meio de autoamostragem para rastreamento de câncer do colo do útero

ABSTRACT Objective. To compare the adequacy, agreement, and acceptability of Papanicolaou testing (cytology) for cervical cancer screening using self-collected samples compared to physician-collected samples in Grenada in the Caribbean. Furthermore, the study identifies the human papillomavirus (HPV) genotypes present among asymptomatic women testing positive for HPV, the etiologic cause of cervical cancer. Methods. Participants were divided into two groups and two cervical samples were collected from the women in each group: a self-collected sample and a physician-collected sample. Cervical specimens were tested for cytology and HPV. HPV genotyping was performed on positive specimens. Results. Self-collected samples were adequate and in agreement with physician-collected samples, showing no difference between the two sampling methods. Oncogenic high-risk HPV genotypes were identified in cervical samples which were positive for atypical squamous cells and low-grade squamous intraepithelial lesions. The high-risk HPV genotypes found, notably HPV 45 and 53, differed from those most commonly reported. Although the commonly reported high-risk genotypes HPV 16 and 18 were found, so were 31, 33, 35, 52, 66, 68, and 82. Conclusions. Using self-collection facilitated the discovery of unexpected HPV genotypes among asymptomatic women in Grenada. These findings add new information to the literature regarding cervical cancer and neoplasia screening and HPV genotypes in the Caribbean. This genotype information may impact surveillance of women with low-grade lesions, HPV vaccine selection, and possibly further vaccine research. Research regarding HPV in Caribbean pathology samples of cervical neoplasia and cancer is needed.

RESUMEN Objetivo. Comparar la idoneidad, concordancia y aceptabilidad de la prueba de Papanicolaou (citología) para el tamizaje del cáncer cervicouterino mediante la comparación de muestras obtenidas con automuestreo y muestras tomadas por personal médico en Granada, en el Caribe. Asimismo, en el estudio se identifican los genotipos del virus del papiloma humano (VPH) existentes en las mujeres asintomáticas con un resultado positivo en las pruebas del VPH, la causa etiológica del cáncer cervicouterino. Métodos. Las participantes se dividieron en dos grupos y se tomaron dos muestras cervicouterinas de las mujeres de cada grupo: una muestra tomada por la propia paciente y una muestra tomada por personal médico. Se realizó un examen citológico y una prueba de detección del VPH en las muestras. En las muestras positivas, se determinó el genotipo del VPH. Resultados. Las muestras tomadas por las propias pacientes fueron adecuadas y concordaron con las obtenidas por el personal médico, sin que se observaran diferencias entre ambos métodos de muestreo. Se identificaron genotipos de VPH de alto riesgo oncogénico en muestras cervicouterinas positivas para células escamosas atípicas y lesiones intraepiteliales escamosas de grado bajo. Los genotipos de VPH de alto riesgo encontrados, en especial VPH 45 y 53, diferían de los notificados con mayor frecuencia. Aunque se encontraron los genotipos de alto riesgo habituales 16 y 18 del VPH, también se encontraron los genotipos 31, 33, 35, 52, 66, 68 y 82. Conclusiones. El uso del automuestreo facilitó la detección de genotipos inesperados del VPH en mujeres asintomáticas de Granada. Estos resultados agregan nueva información a la bibliografía sobre el tamizaje de las neoplasias y el cáncer cervicouterino, así como sobre los genotipos del VPH, en el Caribe. Esta información sobre el genotipo puede repercutir en la vigilancia de las mujeres con lesiones de bajo grado, en la elección de la vacuna contra el VPH y, posiblemente, en las ulteriores investigaciones sobre vacunas. Es necesario investigar la presencia del VPH en muestras anatomopatológicas de neoplasias y cánceres cervicouterinos en el Caribe.

RESUMO Objetivo. Comparar a adequação, o nível de concordância e a aceitabilidade do exame de Papanicolau (citologia) para o rastreamento do câncer do colo do útero usando amostras autocoletadas em comparação com amostras coletadas por médicos em Granada, no Caribe. Além disso, o estudo identifica os genótipos de papilomavírus humano (HPV) presentes entre as mulheres assintomáticas com resultado positivo para HPV, a causa etiológica do câncer do colo do útero. Métodos. As participantes foram divididas em dois grupos, e duas amostras cervicais foram coletadas das mulheres de cada grupo: uma amostra autocoletada e uma amostra coletada por um médico. As amostras cervicais foram submetidas a exames citológicos e de HPV. A genotipagem do HPV foi realizada nas amostras positivas. Resultados. As amostras autocoletadas eram adequadas e compatíveis com as amostras coletadas por médicos, não havendo diferença entre os dois métodos de amostragem. Foram identificados genótipos de HPV de alto risco oncogênico em amostras cervicais positivas para células escamosas atípicas e lesões intraepiteliais escamosas de baixo grau. Os genótipos de HPV de alto risco encontrados, principalmente HPV 45 e 53, não correspondiam aos genótipos registrados com mais frequência na literatura.

Current Insights on Neoplasms and Adequate Dental Care for Patients with Oral Cancer / Actualización sobre Neoplasmas y su Correcta Atención Odontológica en Pacientes con Cancer Oral

The present study aimed to review the literature on the main complications of antineoplastic therapies and the degree of knowledge of dental surgeons about these complications. A bibliographic search was conducted in the main health databases PUBMED (www.pubmed.gov) and Scholar Google (www.scholar.google.com.br), in which studies published from 1987 to 2023 were collected. Laboratory studies, case reports, systematic and literature reviews, which were developed in living individuals, about the main neoplastic genes and their relationship with the cells of individuals affected by neoplasms in the head and neck region, and studies on the care with this group of patients, were included. Therefore, articles that did not deal with neoplasm and the main complications of antineoplastic therapies were excluded. Neoplasm is a clonal disorder, caused by mutations, resulting from changes in the genetic structure of cells. Each healthy cell has instructions on how to grow and divi de. In the presence of any error in these instructions (mutation), it can result in a diseased cell that, when proliferating, may cause a tumor. Countless knowledge has been accumulated over the years on the main characteristics of neoplasms, whether they are cancer cell biology, carcinogenesis mechanism, neoplasms of the maxillofacial system and sequels of antineoplastic treatments. In this context, methods have been developed that offer a better quality of life for patients diagnosed with this pathology, as well as preventive vaccine models that may, in the not too distant future, contribute to this goal to be successfully achieved.

El presente estudio tuvo como objetivo revisar la literatura sobre las principales complicaciones de las terapias antineoplásicas y el grado de conocimiento de los odontólogos sobre este abordaje. Se realizó una búsqueda bibliográfica en las principales bases de datos de salud PUBMED (www.pubmed.gov) y Scholar Google (www.scholar.google.com.br), en la que se recopilaron estudios publicados entre 1987 y 2023. Fueron incluidos estudios de laboratorio, relatos de casos, revisiones de la literatura y revisiones sistemáticas, desarrolladas en individuos vivos, que incluyeran los principales genes neoplásicos y su relación con las células de individuos afectados por neoplasias en la cabeza y el cuello. También, se tuvieron en cuenta estudios relacionados con la atención a este grupo de pacientes. La neoplasia es un trastorno clonal, causado por mutaciones, como resultado de cambios en la estructura genética de las células. Cada célula sana tiene instrucciones sobre cómo crecer y dividirse. En presencia de cualquier error en estas instrucciones (mutación), puede provocar una célula alterada que, al proliferar, puede causar un tumor. Se han acumulado innumerables conocimientos a lo largo de los años sobre las principales características de las neoplasias, ya sea sobre biología de células cancerosas, el mecanismo de la carcinogénesis, la neoplasias del sistema maxilofacial y las diferentes secuelas de tratamientos antineoplásicos. En este contexto, se han desarrollado métodos que ofrecen una mejor calidad de vida para los pacientes diagnosticados con esta patología, así como modelos de vacunas preventivas que, en un futuro no muy lejano, pueden contribuir a alcanzar este objetivo con éxito.

A New Brazilian Device for Cervical Cancer Screening: Acceptability and Accuracy of Self-sampling / Um Novo Dispositivo Brasileiro para Diagnóstico de Câncer Cervical: Aceitabilidade e Precisão da Autoamostragem

Abstract Objective To evaluate the accuracy and patient acceptability toward self-sampling using a new device - SelfCervix® - for detecting HPV-DNA. Methods A total of 73 women aged 25-65 who underwent regular cervical cancer screening from March to October 2016 were included. Women performed self-sampling followed by a physician-sampling, and the samples were analyzed for HPV-DNA. After that, patients were surveyed about their acceptability of self-sampling. Results HPV-DNA detection rate of self-sampling presented high accuracy and was similar to physician-collection. Sixty-four (87.7%) patients answered the acceptability survey. Most patients (89%) considered the self-sampling comfortable, and 82.5% preferred self-sampling to physician-sampling. The reasons cited were time-saving and convenience. Fifty-one (79.7%) reported that they would recommend self-sampling. Conclusion Self-sampling using the new Brazilian device SelfCervix® is not inferior in HPV-DNA detection rate compared with physician-collection, and patients are supportive of the method. Therefore, it might be an option to reach under-screened populations in Brazil.

Computer-aided diagnosis system versus conventional reading system in low-dose (< 2 mSv) computed tomography: comparative study for patients at risk of lung cancer

ABSTRACT BACKGROUND: Computer-aided diagnosis in low-dose (≤ 3 mSv) computed tomography (CT) is a potential screening tool for lung nodules, with quality interpretation and less inter-observer variability among readers. Therefore, we aimed to determine the screening potential of CT using a radiation dose that does not exceed 2 mSv. OBJECTIVE: We aimed to compare the diagnostic parameters of low-dose (< 2 mSv) CT interpretation results using a computer-aided diagnosis system for lung cancer screening with those of a conventional reading system used by radiologists. DESIGN AND SETTING: We conducted a comparative study of chest CT images for lung cancer screening at three private institutions. METHODS: A database of low-dose (< 2 mSv) chest CT images of patients at risk of lung cancer was viewed with the conventional reading system (301 patients and 226 nodules) or computer-aided diagnosis system without any subsequent radiologist review (944 patients and 1,048 nodules). RESULTS: The numbers of detected and solid nodules per patient (both P < 0.0001) were higher using the computer-aided diagnosis system than those using the conventional reading system. The nodule size was reported as the maximum size in any plane in the computer-aided diagnosis system. Higher numbers of patients (102 [11%] versus 20 [7%], P = 0.0345) and nodules (154 [15%] versus 17 [8%], P = 0.0035) were diagnosed with cancer using the computer-aided diagnosis system. CONCLUSIONS: The computer-aided diagnosis system facilitates the diagnosis of cancerous nodules, especially solid nodules, in low-dose (< 2 mSv) CT among patients at risk for lung cancer.

An assessment of knowledge regarding breast cancer among educated women in Kanpur Nagar, Uttar Pradesh, India

Background: Most common female cancer worldwide including India is breast cancer. Awareness about breast cancer is very necessary for early detection and prevention as diagnosis at advanced stages of disease contributes to the high mortality rate. An assessment of existing levels of knowledge regarding cancer is a pre-requisite to find out gaps and to plan for proper educational programmes. Methods: This cross-sectional study was carried out in a women’s college, study subjects were students, female faculty members and female staff. A structured questionnaire was given, data was collected and analysed. Results: In this study it is found that knowledge regarding risk factors for breast cancer was low, only 47.68% knew that family history predisposes for breast cancer, 28.48% knew late menopause is risk factor. 76.82% of respondents knew that lump in breast is a sign of breast cancer, whereas only 31.13% knew that discharge from nipple is sign of breast cancer. Merely 6.40% of respondents knew the procedure of breast self-examination. Majority of respondents i.e. 54.53% told media as source of information. Conclusions: Regarding breast cancer low level of knowledge was found among the study subjects which suggests that proper information should be provided in colleges, especially health facilities and schools should increase their role in providing related information.
