ABSTRACT

Introducción: El cáncer de pulmón (CP) es una enfermedad con gran impacto a nivel mundial en el número de muertes y en costos en salud. La alta incidencia y mortalidad de esta enfermedad asociada al diagnóstico tardío, y la mejoría del pronóstico ante una detección temprana, determinan que sea una patología pasible de beneficiarse mediante detección temprana. La tomografía de baja dosis de radiación (TCBD) demostró ser un método que se pue- de realizar periódicamente a un grupo de personas con alto riesgo de desarrollar CP y así reducir la mortalidad por esta enfermedad. Sin embargo, este beneficio es tal cuan- do se encuentra desarrollado bajo un programa organizado y con participación multi- disciplinaria especializada en cáncer de pulmón. Métodos: Se plantea determinar lineamientos básicos para el desarrollo de la detección temprana de cáncer de pulmón en América Latina para que pueda ser realizada en forma uniforme, con el menor riesgo y el máximo beneficio esperado. Se analizaron las principales publicaciones referidas a este tema, contemplando la diversidad de atención y acceso de América Latina. Resultado: Se desarrollan requerimientos mínimos para la implementación de un pro- grama. Discusión: El número de programas en la región es escaso y depende más de esfuerzos individuales que de políticas generales de salud. Consideramos que estos lineamien- tos pueden servir de apoyo para el desarrollo de más programas en la región y de for- ma más homogénea.


Introduction: Lung cancer (LC) is a disease with a great impact worldwide in the number of deaths and health costs. The high incidence and mortality of this disease associated with late diagnosis and the improved prognosis with early detection determine that it is a pathology that can benefit from early detection. Low radiation dose tomography (LDCT) demonstrated a method that can be performed periodically to a group of people at high risk of developing CP and thus reduce mortality from this disease. However, this benefit is such when it is developed under an organized program with multidisciplinary participation specialized in lung cancer. Methods: It is proposed to determine basic guidelines for the development of early de- tection of lung cancer in Latin America so that it can be carried out uniformly, with the lowest risk and the maximum expected benefit. The main publications referring to this topic were analyzed, considering the diversity of care and access in Latin America. Result: Minimum requirements are developed for the implementation of a program. Discussion: The number of programs in the region is small and depends more on individual efforts than on general health policies. We consider that these guidelines can serve as support for the development of more programs in the region and in a more ho- mogeneous way.

ABSTRACT

O câncer é uma doença crônico-degenerativa, que tem como uma de suas principais características a capacidade de invadir tecidos e órgãos do corpo, favorecendo o crescimento desordenado de células. É uma doença que impacta fortemente a pessoa enferma e todos à sua volta, incluindo sua família e seus amigos. A partir desse cenário, este trabalho visou compreender a visão da criança e o impacto emocional sofrido diante do diagnóstico de câncer da mãe. Buscou-se avaliar, a partir de ferramentas lúdicas e do desenho-estória, o entendimento da criança em relação ao processo de adoecimento materno, tomando como base o referencial psicanalítico para reconhecer como ela lidou com a situação. Participaram desta pesquisa uma mulher de 39 anos com diagnóstico de câncer em remissão e seu filho de 9 anos. Os resultados demonstraram que o adoecimento materno causou impactos emocionais significativos e assustadores para o infante, gerando fantasias irreais relacionadas ao câncer e a si próprio. Dessa forma, considera-se de fundamental importância o cuidado estendido aos familiares do indivíduo doente, a fim de que se tenha um olhar a todos que sofrem diante desse contexto.(AU)


Cancer is a chronic-degenerative disease that has as one of its main characteristics the ability to invade tissues and organs of the body, favoring the disordered cell growth. It is a disease that strongly impacts the sick person and everyone around them, including their family and friends. Based on this scenario, this work aimed to understand the child's view and the emotional impact suffered in the face of the mother's cancer diagnosis. It sought to evaluate, with ludic tools and drawing history, the child's understanding about the mother's illness process, based on the psychoanalytic framework to recognize how they deal with the situation. A 39-year-old woman diagnosed with cancer, in remission, and her 9-year-old son participated in this research. The results showed that the maternal illness caused significant and frightening emotional impacts for the infant, creating unrealistic fantasies related to cancer and to himself. Thus, the care extended to the sick individual's family and to the relatives is considered of fundamental importance, to give a complete care for all those who suffer in this context.(AU)

Enfermedades como esta impactan fuertemente a la persona que está enferma y a todos los que la rodean, incluidos familiares y amigos. Considerando esta situación, este estudio tuvo como objetivo comprender la percepción de un niño y el impacto emocional que sufrió ante el diagnóstico del cáncer vivido por su madre. Se pretendió evaluar, utilizando herramientas lúdicas y de dibujo-cuento, la comprensión del niño al proceso de enfermedad materna, buscando reconocer cómo el niño manejó este proceso a partir del referencial teórico psicoanalítico. En esta investigación participaron una mujer de 39 años diagnosticada de cáncer en remisión y su hijo de 9 años. Los resultados mostraron que los impactos emocionales de la enfermedad materna fueron significativos y aterradores para el infante, generando fantasías irreales relacionadas con el cáncer y él mismo. De esta forma, el cuidado extendido a la familia del individuo que está enfrentando esta enfermedad es importante para promover una atención integral a quienes la padecen en este contexto.(AU)

ABSTRACT

A sobrevivência ao câncer de mama é um problema de saúde pública que demanda serviços especializados com foco na reabilitação psicossocial. Entre as necessidades identificadas nesse contexto está o incentivo à adoção de estratégias de promoção de autocuidados pelas mulheres. Uma das estratégias adotadas consiste no grupo de apoio psicológico, que auxilia as pacientes a enfrentar a longa jornada do tratamento. Assim, o objetivo deste estudo é compreender os significados produzidos por mulheres com câncer de mama sobre sua participação em um grupo de apoio. Trata-se de um estudo qualitativo, descritivo e exploratório realizado com dez mulheres com câncer de mama usuárias de um serviço de reabilitação para mastectomizadas. Como referencial metodológico foi utilizada a Teoria Fundamentada nos Dados. A coleta de dados foi realizada por meio de entrevista aberta em profundidade e os conteúdos foram transcritos e codificados. A análise indutiva e o método de comparação constante foram aplicados nos processos de codificação aberta, axial e seletiva, que permitiram identificar três categorias nucleares: percepção das atividades realizadas no grupo, identificação de benefícios e barreiras do convívio no grupo e transformações decorrentes da participação. As participantes significaram sua presença no grupo como fonte de acolhimento, apoio, desenvolvimento de recursos pessoais e amizades, contribuindo para promover sua qualidade de sobrevida. Além dos potenciais benefícios, também foram identificadas barreiras que podem dificultar a adesão e continuidade da participação no grupo, o que sugere a necessidade de incorporar no cuidado um olhar para as dimensões subjetivas da saúde da mulher.(AU)


Surviving breast cancer is a public health problem and depends on services focused on psychosocial rehabilitation. Healthcare providers must encourage women to adopt strategies to promote their self-care. The psychological support group is a resource that helps women to face the long journey of treatment. This study aimed to understand the meanings women with breast cancer produced about their participation in a support group. This exploratory cross-sectional study was carried out with 10 women with breast cancer who use a rehabilitation service for mastectomized patients. Grounded Theory was used as a methodological reference. An open in-depth interview was applied for data collection. The contents were transcribed and coded. Inductive analysis and the constant comparison method were applied in the open, axial, and selective coding processes, which enabled the identification of three core categories: perception of the activities carried out in the group, identification of benefits and barriers of living in the group, and transformations resulting from participation. Participants denote their involvement with the group as a source of shelter, support, development of personal resources and friendships that helps promoting quality of life. Besides these potential benefits, participants also evinced barriers that can hinder adherence and continuity of participation in the group, suggesting the importance of incorporating a look at the subjective dimensions of women's health into care.(AU)

ABSTRACT

BACKGROUND@#Low-dose spiral computed tomography (LDCT) has been recommended for lung cancer screening in high-risk populations. However, evidence from Chinese populations was limited due to the different criteria for high-risk populations and the short-term follow-up period. This study aimed to evaluate the effectiveness in Chinese adults based on the Lung Cancer Screening Program in Minhang District of Shanghai initiated in 2013.@*METHODS@#A total of 26,124 subjects aged 40 years or above were enrolled in the Lung Cancer Screening Program during the period of 2013 and 2017. Results of LDCT examination, and screen-detected cancer cases in all participants were obtained from the Reporting System of the Lung Cancer Screening Program. The newly-diagnosed cases and their vital status up to December 31, 2020 were identified through a record linkage with the Shanghai Cancer Registry and the Shanghai Vital Statistics. Standardized incidence ratio (SIR) and 95%CI were calculated using the local population at ages of 40 or above as the reference. Proportions of early-stage cancer (stage 0-I), pathological types, and 5-year observed survival rates of lung cancer cases were estimated and compared between the cases derived from the screened and non-screened populations. Cox regression models were applied to evaluate the hazard ratio (HR) and 95%CI of LDCT screening with all-cause death of the lung cancer cases.@*RESULTS@#The crude and age-standardized incidence of lung cancer in screened population were 373.3 (95%CI: 343.1-406.1) and 70.3 per 100,000 person-years, respectively, with an SIR of 1.8 (95%CI: 1.6-1.9), which was observed to decrease with following-up time. The early-stage cancer accounted for 49.4% of all lung cancer cases derived from the screened population, significantly higher than 38.4% in cases from the non-screened population during the same period (P<0.05). The proportion of lung adenocarcinoma (40.7% vs 35.9%) and 5-year survival rate (53.7% vs 41.5%) were also significantly higher in the cases from the screened population (all P<0.05). LDCT screening was associated with 30% (HR=0.7, 95%CI: 0.6-0.8) reduced all-cause deaths of the cases.@*CONCLUSIONS@#The participants of the screening program are at high-risk of lung cancer. LDCT favors the early-detection of lung cancer and improves 5-year survival of the screened cases, indicating a great potential of LDCT in reducing the disease burden of lung cancer in Chinese populations.

ABSTRACT

As alterações orais potencialmente malignas e o câncer oral, quando diagnosticados precocemente, possuem um bom prognóstico. No entanto, a imprecisão nos atendimentos odontológicos dificulta a detecção precoce, fazendo com que o câncer bucal permaneça como um problema de saúde pública atualmente. Objetivo: Avaliar o conhecimento de graduandos em odontologia sobre lesões orais de câncer e alterações orais potencialmente malignas. Método: Os dados foram coletados por meio de um questionário virtual, enviado para graduandos de odontologia de algumas universidades/faculdades localizadas no Estado da Bahia, entre os meses de junho e outubro de 2022. Posteriormente, os dados foram analisados estatisticamente e quatro conceitos foram estabelecidos: A (ótimo nível de informação); B (bom nível de informação); C (nível insatisfatório de informação); e D (péssimo nível de informação). Resultados: A amostra foi composta por 161 estudantes, a maioria entre 20 e 29 anos e do sexo feminino (78,3%). Não houve uma diferença estatística significativa entre os estudantes com até um ano de aprovação em componentes curriculares de estomatologia, patologia ou correlatos, com discentes com mais de um ano de aprovação (p = 0,126). A leucoplasia foi a alteração mais relacionada ao câncer (77%) para os entrevistados, e apenas 23% dos graduandos obtiveram o conceito A; no entanto, 96,9% dos entrevistados possuem interesse em assistir ao curso de educação contínua sobre o assunto. Conclusão: A maioria dos acadêmicos avaliados apresentou um bom nível de informação, entretanto, observou-se que os fatores de risco e a localização das lesões malignas geraram grandes dúvidas nos participantes deste estudo.


Potentially malignant oral disorders and oral cancer in early stages, when diagnosed early, have good prognosis. However, oral cancer is a public health problem today due to imprecision of dental care which makes early detection difficult. Objective: To evaluate the knowledge of dental students about oral cancer lesions and potentially malignant oral disorders. Method: Data were collected through a virtual questionnaire sent to undergraduate dentistry students from some universities/colleges located in the state of Bahia, between June and October 2022. Subsequently, the data were statically analyzed and four concepts were established: A (excellent level of information); B (good level of information); C (unsatisfactory level of information) and D (very poor level of information). Results: The sample consisted of 161 female students (78.3%) mostly between 20 and 29 years old. There was no statistically significant difference between students with up to one year of approval in stomatology, pathology or related disciplines, an students with more than one year of approval (p = 0.126). Leukoplakia was the disorder most related to cancer (77%) and only 23% of undergraduates obtained grade A, however, 96.9% of the respondents are interested in attending a continuing education course on the subject. Conclusion: The majority of the students evaluated had good level of information, nevertheless, the study participants had great doubts about the risk factors and the location of malignant lesions.


Los trastornos orales potencialmente malignos y el cáncer oral en estadios tempranos, cuando se diagnostican a tiempo, tienen un buen pronóstico. Sin embargo, la imprecisión en los tratamientos dentales dificulta la detección previa, por lo que el cáncer bucal sigue siendo un problema de salud pública en la actualidad. Objetivo: Evaluar el conocimiento de los estudiantes de odontología sobre las lesiones orales cancerosas y los trastornos orales potencialmente malignos. Método: Los datos fueron recolectados a través de un cuestionario virtual, enviado a estudiantes de grado en odontología de algunas universidades/facultades ubicadas en el estado de Bahía, entre junio y octubre de 2022. Posteriormente, los datos fueron analizados estadisticamente y se establecieron cuatro conceptos: A (nivel excelente de información); B (buen nivel de información); C (nivel de información insatisfactorio) y D (nivel de información muy bajo). Resultados: La muestra estuvo conformada por 161 estudiantes, la mayoría entre 20 y 29 años y de sexo femenino (78,3%). No hubo diferencia estadísticamente significativa entre estudiantes con hasta un año de aprobación en estomatología, patología o disciplinas afines, con estudiantes con más de un año de aprobación (p=0,126). La leucoplasia fue el trastorno que más se relacionó con el cáncer (77%) y solo el 23% de los estudiantes de pregrado obtuvo la calificación A, sin embargo, el 96,9% de los encuestados está interesado en asistir a un curso de educación continua sobre el tema. Conclusión: La mayoría de los estudiantes evaluados presentaron un buen nivel de información, sin embargo, se observó que los factores de riesgo y la localización de las lesiones malignas generaron grandes dudas entre los participantes de este estudio

ABSTRACT

A mamografia é o método de eleição para o rastreamento do câncer de mama, sendo o único que demonstra redução de mortalidade na população de risco habitual. A periodicidade de realização e a idade de início do rastreamento mamográfico são um tema controverso na literatura. Entretanto, dados no nosso país apontam para uma porção significativa de neoplasia de mamas em mulheres abaixo dos 50 anos. A Federação Brasileira das Associações de Ginecologia e Obstetrícia (Febrasgo), a Sociedade Brasileira de Mastologia (SBM) e o Colégio Brasileiro de Radiologia e Diagnóstico por Imagem (CBR) concordam que o rastreamento mamográfico deveria ser realizado, anualmente, por todas as mulheres a partir de 40 anos de idade. No Brasil, há uma distribuição desigual de mamógrafos nas várias regiões. As políticas de rastreamento devem considerar essa desigualdade. A grande maioria dos serviços no Brasil realiza rastreamento oportunístico para o câncer de mama. A implantação de rastreamento organizado por faixa etária e estratificação de risco pode otimizar os custos do sistema público de saúde. Pacientes de alto risco precisam ser rastreadas de forma diferente das pacientes de risco habitual. Essas pacientes precisam ter acesso à ressonância magnética das mamas e também iniciar seu rastreamento em idade mais precoce. O protocolo abreviado da ressonância magnética para rastreamento de pacientes de alto risco para câncer de mama pode melhorar a adesão e o acesso dessas pacientes ao programa de rastreamento. A ultrassonografia das mamas não é método de rastreamento isoladamente. Entretanto, ela tem seu papel como método complementar à mamografia e à ressonância magnética em cenários específicos, bem como em substituição à ressonância magnética em pacientes com contraindicação ao uso desse método. As mamas densas possuem baixa sensibilidade para o rastreamento por mamografia

ABSTRACT

Objetivos: Instruir e orientar ao cirurgião dentista e demais profissionais de saúde a importância da detecção e rastreio precoce de lesões pré-malignas. Revisão de Literatura: O Líquen Plano Oral é uma condição dermatológica crônica, de origem auto-imune, relativamente comum na população, que atinge o epitélio de mucosa e pele, sendo considerada, pela Organização Mundial de Saúde (OMS), uma desordem potencialmente maligna quando associado a áreas de ulceração. A revisão de literatura foi realizada nas bases de dados PubMed e Lilacs. Buscamos investigar o potencial de malignização do Líquen Plano Oral associado a condições erosivas, analisando o processo de carcinogênese no processo inflamatório. Conclusão: Conclui-se que o objeto de estudo ainda é um assunto pouco explorado pela literatura, porém há indícios etiopatológicos que enfatizam o processo de malignização oriundo de uma lesão pré-maligna como o Líquen Plano Oral. Além disso, enfatizamos a importância do diagnóstico precoce das lesões estomatognáticas, para que assim possamos aumentar as chances de cura do paciente.(AU)


Objectives: To instruct and guide dentists and other health professionals on the importance of early detection and screening of pre-malignant lesions. Literature Review: Oral Lichen Planus is a chronic dermatological condition, of autoimmune origin, relatively common in the population, which affects the epithelium of the mucosa and skin, being considered, by the World Health Organization (WHO), a potentially fatal disorder. malignant when associated with areas of ulceration. A literature review was performed on the PubMed and Lilacs databases. We sought to investigate the potential for malignancy of Oral Lichen Planus associated with erosive conditions, analyzing the process of carcinogenesis in the inflammatory process. Conclusion: It is concluded that the object of study is still a subject little explored in the literature, but there are etiopathological accusations that emphasize the process of malignancy arising from a pre-malignant lesion such as Oral Lichen Planus. In addition, we emphasize the importance of early diagnosis of stomatognathic lesions, so that we can increase the patient's chances of cure.(AU)

ABSTRACT

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.


Resumo Objetivo Avaliar a acurácia e aceitabilidade da auto-coleta utilizando um novo coletor - SelfCervix® - para a detecção de DNA de HPV. Métodos Foram incluídas no estudo 73 mulheres com idade entre 25-65 anos que realizaram seu rastreamento regular do câncer de colo do útero entre Março e Outubro de 2016. Estas mulheres realizaram a auto-coleta, seguida de coleta profissional e as amostras foram analisadas paraa presença de DNA de HPV. Após, elas responderam um questionário sobre a experiência da auto-coleta. Resultados As taxas de detecção de DNA de HPV por auto-coleta foram altas e similares as da coleta profissional. Sessenta e quatro (87,7%) pacientes responderam o questionário de experiência. A maioria (89%) considerou a auto-coleta confortável, e 82,5% preferiram o método comparado a coleta profissional. As razões citadas foram economia de tempo e conveniência. Cinquenta e uma (79,7%) mulheres confirmaram que recomendariam a auto-coleta. Conclusão Auto-coleta utilizando o novo coletor desenvolvido no Brasil não é inferior na detecção de DNA de HPV quando comparada a coleta profissional, e apresenta uma boa aceitabilidade pelas mulheres. Desta maneira, pode ser uma opção para alcançar populações que não realizam o rastreamento padrão.

ABSTRACT

Cervical cancer is still one of the leading causes of cancer and mortality in women, especially in low- and middle-income countries. Normally, the prevention of its occurrence is done through efficient screening and treatment programs for high-grade epithelial lesions, which are pre-malignant lesions. Cheaper diagnostic techniques ensure greater access to women, which can prevent a large number of cancer cases worldwide. Objective: The aim of the study was to evaluate the accuracy of visual inspection either with acetic acid or with Lugol's iodine, cervical cytology and colposcopy in the diagnosis of cervical intraepithelial neoplasia 2 and 3. Methods: This is a study of diagnostic accuracy. We evaluated 115 women with high-grade squamous intraepithelial lesion confirmed by biopsy, 54 with cervical intraepithelial neoplasia 2 and 61 with cervical intraepithelial neoplasia 3, from January 2016 to December 2018 at the Lower Genital Tract Pathology and Colposcopy Service of the Hospital de Clínicas de Porto Alegre, Porto Alegre, Brazil. A comparative analysis of the visual inspection, Pap smear and colposcopy diagnostic methods was performed. Results: The average age was 33.1 years (standard deviation=9.83) for cervical intraepithelial neoplasia 2 cases and 35.2 years (standard deviation=7.97) for cervical intraepithelial neoplasia 3. In the cervical intraepithelial neoplasia 2 group, visual inspection tests were positive for high-grade squamous intraepithelial lesion in 98.1% of the cases with acetic acid and 94.4% with Lugol's iodine. Colposcopy identified a probable high-grade squamous intraepithelial lesion in 94.4% of the cases, while cytology only in 42.6%. In the cervical intraepithelial neoplasia 3 group, the visual inspection tests were positive for high-grade squamous intraepithelial lesion in 91.8% of the cases with acetic acid and 95.1% with Lugol's iodine. Colposcopy identified a probable high-grade squamous intraepithelial lesion in 93.5% of the cases, while cytology in 65.6%. Conclusion: Visual inspection with acetic acid and Lugol's iodine, and colposcopy test were more accurate for the diagnosis of cervical intraepithelial neoplasia 2 and 3 than through cytopathology.

Introdução: O câncer do colo de útero ainda é uma das principais causas de câncer e mortalidade em mulheres, especialmente em países de baixa e média renda. Normalmente, a prevenção de sua ocorrência é feita por meio de programas eficientes de triagem e tratamento de lesões epiteliais de alto grau, que são as lesões pré-malignas. Técnicas diagnósticas mais baratas garantem maior acesso às mulheres, podendo evitar um grande número de casos de câncer no mundo inteiro. Objetivo: O objetivo deste estudo foi avaliar a acurácia da inspeção visual (com ácido acético e com solução de lugol), da citologia cervical e da colposcopia no diagnóstico de neoplasias intraepiteliais cervicais 2/3. Métodos: Trata-se de um estudo de acurácia diagnóstica. Foram avaliadas 115 mulheres com lesão intraepitelial escamosa de alto grau confirmada por biópsia, 54 com neoplasias intraepiteliais cervicais 2 e 61 com neoplasias intraepiteliais cervicais 3, no período de janeiro de 2016 a dezembro de 2018 no Serviço de Patologia e Colposcopia do Trato Genital Inferior do Hospital de Clínicas de Porto Alegre, em Porto Alegre, Brasil. Foi realizada análise comparativa dos métodos de diagnóstico Inspeção visual com ácido acético, Inspeção visual com Solução de Lugol, colpocitologia oncótica e colposcopia. Resultados: A média de idade foi de 33,11 anos (DP 9,83) para os casos de neoplasias intraepiteliais cervicais 2 e de 35,28 anos (DP 7,97) para neoplasias intraepiteliais cervicais 3. No grupo de neoplasias intraepiteliais cervicais 2, os testes de inspeção visual foram positivos para tratamento de lesões epiteliais de alto grau em 98,1% dos casos com Inspeção visual com ácido acético e em 94,4% daqueles com Inspeção visual com Solução de Lugol. A colposcopia identificou provável tratamento de lesões epiteliais de alto grau em 94,4% dos casos, enquanto a citologia apenas 42,6%. No grupo neoplasias intraepiteliais cervicais 3, os testes de inspeção visual foram positivos para tratamento de lesões epiteliais de alto grau em 91,8% dos casos com Inspeção visual com ácido acético e em 95,1% daqueles com Inspeção visual com Solução de Lugol. A colposcopia identificou provável tratamento de lesões epiteliais de alto grau em 93,5% dos casos, enquanto a citologia em 65,6%. Conclusão: A inspeção visual (com ácido acético e com Solução de Lugol) e a colposcopia foram mais precisas para o diagnóstico de neoplasias intraepiteliais cervicais 2/3 do que a citopatologia.

ABSTRACT

O presente estudo buscou investigar a percepção que pacientes adultos de uma unidade de terapia intensiva (UTI) oncológica têm acerca da experiência de internação nesse setor. Trata-se de uma pesquisa de abordagem qualitativa e de compreensão. Sete pacientes de um hospital de câncer na região Sul do país foram pesquisados. Eles responderam a uma entrevista semiestruturada, a qual foi gravada e posteriormente transcrita, o que possibilitou o acesso às concepções prévias desses sujeitos acerca da UTI, aspectos psicológicos presentes durante a internação e concepções posteriores à experiência de internamento na unidade. Tais informações foram interpretadas por meio da análise de conteúdo. A partir dos resultados, foi possível verificar que a experiência de internação em contextos de terapia intensiva pode ser afetada, favorável ou desfavoravelmente, pelo conjunto de regras que o paciente traz consigo acerca do que é a UTI. Além disso, foi possível compreender também que os estímulos aversivos existentes nesse ambiente podem ser atenuados pela presença da família e por uma relação acolhedora e sensível com a equipe de saúde, favorecendo, assim, o repertório de enfrentamento do paciente frente a esse momento crítico de saúde.(AU)


This study aims to investigate the perception of adult patients in an oncology intensive care unit (ICU) regarding the experience of hospitalization in this sector. This is a research with a qualitative approach and understanding. Seven patients from a cancer hospital in the southern region of the country were surveyed. They answered a semi-structured interview, which was recorded and later transcribed, on the subjects' previous conceptions about the ICU, psychological aspects present during hospitalization, and conceptions subsequent to the hospitalization experience in the Unit. Such information was interpreted through content analysis. From the results, it was possible to verify that the experience of hospitalization in intensive care contexts can be affected, favorably or unfavorably, by the set of rules that the patient brings with them about what the ICU is. In addition, it was also possible to understand that the aversive stimulus existing in this environment can be attenuated by the presence of the family and by a welcoming and sensitive relationship with the health team, thus favoring the patient's coping repertoire when facing a critical moment of health.(AU)

ABSTRACT

Abstract Objective To evaluate the rates of precancerous lesions, colposcopy referral, and positive predictive value (PPV) by age groups of a population-based screening with DNA-HPV testing. Methods The present demonstration study compared 16,384 HPV tests performed in the first 30 months of the program with 19,992 women tested in the cytology screening. The colposcopy referral rate and PPV for CIN2+ and CIN3+ by age group and screening program were compared. The statistical analysis used the chi-squared test and odds ratio (OR) with 95% confidence interval (95%CI). Results The HPV tests were 3.26% positive for HPV16-HPV18 and 9.92% positive for 12 other HPVs with a 3.7 times higher colposcopy referral rate than the cytology program, which had 1.68% abnormalities. Human Papillomavirus testing detected 103 CIN2, 89 CIN3, and one AIS, compared with 24 CIN2 and 54 CIN3 detected by cytology (p < 0.0001). The age group between 25 and 29 years old screened by HPV testing had 2.4 to 3.0 times more positivity, 13.0% colposcopy referral, twice more than women aged 30 to 39 years old (7.7%; p < 0.0001), and detected 20 CIN3 and 3 early-stage cancer versus 9 CIN3 and no cancer by cytology screening (CIN3 OR= 2.10; 95%CI: 0.91 -5.25; p = 0.043). The PPV of colposcopy for CIN2+ ranged from 29.5 to 41.0% in the HPV testing program. Conclusion There was a significant increase in detections of cervix precancerous lesions in a short period of screening with HPV testing. In women < 30 years old, the HPV testing exhibited more positivity, high colposcopy referral rate, similar colposcopy PPV to older women, and more detection of HSIL and early-stage cervical cancer.


Resumo Objetivo Avaliar as taxas de lesões pré-cancerosas, encaminhamento para colposco pia e valor preditivo positivo (VPP) por faixas etárias de rastreamento populacional com teste DNA-HPV. Métodos O presente estudo de demonstração comparou 16.384 testes de HPV realizados nos primeiros 30 meses do programa com 19.992 mulheres testadas no rastreio citológico. Os programas foram comparados por taxa de encaminhamento de colposcopia e VPP para NIC2+ e NIC3+ por faixa etária. A análise estatística utilizou o teste de qui-quadrado e odds ratio (OR, na sigla em inglês) com intervalo de confiança (IC) de 95%. Resultados Os testes de HPV foram 3,26% positivos para HPV16-HPV18 e 9,92% positivos para 12 outros HPVs, com uma taxa de encaminhamento de colposcopia 3,7 vezes maior do que o programa de citologia, que teve 1,68% de anormalidades. O teste de HPV detectou 103 NIC2, 89 NIC3 e um AIS, em comparação com 24 NIC2 e 54 NIC3 detectados por citologia (p < 0,0001 ). O rastreio por teste de HPV no grupo etário 25 a 29 anos teve 2,4 a 3,0 vezes mais positividade, 13,0% de encaminhamento para colposcopia, 2 vezes mais que mulheres de 30 a 39 anos (7,7%; p < 0,0001 ), e detectou 20 NIC3 e 3 cânceres em estágio inicial versus nove NIC3 e nenhum câncer pelo rastreio citológico (NIC3 OR= 2,10; 96%CI: 0,91 -5,25; p = 0,043). O VPP da colposcopia para NIC2+ variou de 29,5 a 41,0% no programa de teste de HPV. Conclusão Houve um aumento significativo na detecção de lesões pré-cancerosas do colo do útero em um curto período de rastreamento com teste de HPV. Em mulheres < 30 anos, o teste de HPV exibiu mais positividade, alta taxa de encaminhamento para colposcopia com VPP semelhante a mulheres mais velhas, e mais detecção de HSIL e de câncer cervical em estágio inicial.

ABSTRACT

O câncer de pulmão é reconhecidamente um dos mais agressivos dentre os tumores, com alta letalidade. A detecção precoce do câncer de pulmão com tomografia computadorizada de baixa dose tem sido avaliada em diversos países e implementada em alguns. Entretanto, a implementação do rastreamento com uso dessa tecnologia para detecção precoce de novos casos, permanece questionado no mundo, e no Brasil não está recomendado. Por esse motivo, foi elaborada uma avaliação de custo-efetividade do uso da tomografia computadorizada de baixa dose como estratégia de rastreamento para detecção precoce do câncer de pulmão em população de risco sob a perspectiva do Sistema Único de Saúde como órgão financiador. Inicialmente uma revisão sistemática foi elaborada e descrita uma síntese das diferentes abordagens disponíveis nas avaliações econômicas. Os 30 estudos selecionados e incluídos na revisão mostraram qualidade global, com bom padrão metodológico, que atendeu a mais de 80% dos critérios estabelecidos pelo formulário (Consensus Health Economic Criteria list). A análise da eficiência comparativa entre duas alternativas (anual e bianual) para o diagnóstico precoce de câncer de pulmão, considerando a estratégia de rastreamento com tomografia computadorizada de baixa dose e a conduta clínica sem rastreio, como cenário de referência, teve por base uma coorte hipotética de 100.000 indivíduos assintomáticos, e tabagistas de alto risco. O horizonte temporal considerou a expectativa de vida dos indivíduos, e a perspectiva foi o Sistema Único de Saúde como financiador da assistência à saúde. Apenas os custos médicos diretos dos itens relacionados ao processo de diagnóstico e tratamento foram estimados. O desfecho foi medido em anos de vida ganhos. O desconto de 5% foi aplicado aos custos e benefícios. E realizadas análises de sensibilidade determinística univariada e probabilística. A razão de custo-efetividade incremental da estratégia de rastreamento anual com a tomografia computadorizada de baixa dose para a detecção precoce de câncer de pulmão foi estimada em R$ 97.583,52 por cada ano de vida ganho e de R$ 56.642,20 por ano de vida ganho, com o rastreio a cada dois anos. A análise determinística mostrou que o impacto da redução da incidência de câncer de pulmão, em ambas as alternativas (anual e bianual), chega a gerar quase o triplo dos gastos estimados para a razão de custo-efetividade incremental. Para o anual esse aumento chega a R$ 176.834,47, fora do limiar de R$105.000,00, enquanto o rastreamento bianual, mesmo dobrando os gastos, ainda se manteria dentro do limiar de custo-efetividade atualmente definido para o país. Os demais parâmetros de relevância (sensibilidade do rastreamento para detecção de câncer e a proporção de diagnósticos em estadio I/II com o rastreamento) não impactaram nos resultados finais. A análise probabilística das alternativas de rastreamento mostrou para o rastreamento anual 52% das simulações dentro do limiar estabelecido e 94,2% referente ao bianual. O resultado do modelo econômico mostrou resultados favoráveis com a adoção da estratégia de rastreamento de câncer de pulmão com uso de tomografia computadorizada de baixa dose comparada a condução clínica, realizada a cada dois anos em população de alto risco, sob a perspectiva do SUS.

Lung cancer is one of the most aggressive tumors, with high lethality. Early detection of lung cancer with low-dose computed tomography has been evaluated in several countries and implemented in some. However, the implementation of screening using this technology for early detection of new cases remains questioned worldwide, but in Brazil, it has not been recommended. Thus, a cost-effectiveness assessment of a screening strategy with low-dose computed tomography for early lung cancer detection in a high-risk population under the Unified Health System perspective as a funding body. First, a systematic review was performed and synthesized the different approaches available in economic evaluations. Thirty studies selected and included in the review showed overall quality, with a well-designed methodological standard, which met more than 80% of the criteria established by the Consensus Health Economic Criteria (CHEC) list form. The analysis of the comparative efficiency between two alternatives (annual and biannual) for the early diagnosis of lung cancer, considering the screening strategy with low-dose computed tomography and the clinical management, without screening, as a reference scenario, was based on a cohort hypothetical 100,000 asymptomatic individuals, and high-risk smokers. The time horizon considered the individuals' life expectancy, and the perspective was the Brazilian Unified Health System as the funder of health care. Only the direct medical costs of items related to the diagnosis and treatment process were estimated. The outcome measure was life years gained. A discount of 5% has been applied to costs and benefits. A deterministic and probabilistic sensitivity analysis has been performed. The incremental cost-effectiveness ratio of the annual screening strategy for early lung cancer detection has been estimated at BRL 97,583.52 for each life-year gained and BRL 56,642.20 per year of life gained, with screening every two years. The deterministic analysis showed that the impact of reducing the incidence of lung cancer, in both alternatives (annual and biannual) generated almost three times the estimated expenses for the incremental cost-effectiveness ratio. For the annual survey, this increase reaches BRL 176,834.47, outside the BRL 105,000.00 threshold, while biannual screening, even doubling the expenses, would remain within the cost-effectiveness threshold currently defined for the country. The other relevant parameters (screening sensitivity for cancer detection and the proportion of stage I/II diagnoses with screening) have no impact on the final results. The probabilistic analysis showed that 52% of simulations within the established threshold correspond to the annual screening, and 94.2% to the biannual. The economic model designed to evaluate the cost-effectiveness of lung cancer screening using low-dose computed tomography compared to clinical care showed favorable results from the strategy performed every two years in a high-risk population, under the SUS perspective.

ABSTRACT

Colorectal Cancer (CRC) is the third most frequent neoplasia worldwide. Despite the significant advances in surgical techniques and the development of new targeted antineoplastic therapies for this type of tumor, primary prevention and early diagnosis of malignant precursor lesions will continue to be the best strategies to reduce their incidence, morbidity, and mortality. Technologies for CRC screening can be classified into two groups, those of an invasive nature, such as colonoscopy and all its different modalities of use, and those of a non-invasive nature, such as laboratory tests and imaging. This review, will focus exclusively on non-invasive screening tests, excluding imaging. Specifically, it will address those that use depositions as a sample. This review will approach the latest international recommendations, regarding the age at which they should be used, their technical-biological bases, the two main types currently used (biochemical and immunological), and we will put into perspective their advantages and their possible disadvantages. Towards the end of this article, the most recent biotechnological developments in relation to molecular tests based on the study of blood samples, will be discussed. Although these tests are not yet in routine clinical use given their high costs, they are promising for the early detection of CRC.


El cáncer colorrectal (CCR) es la tercera neoplasia más común en todo el mundo. A pesar de los avances significativos en las técnicas quirúrgicas y en el desarrollo de nuevas terapias antineoplásicas para este tipo de tumor, la prevención primaria y el diagnóstico precoz de lesiones precursoras malignas siguen siendo las mejores estrategias para reducir la incidencia, morbilidad y mortalidad asociadas al CCR. Existen dos tipos de tecnologías para el tamizaje del CCR: las invasivas, como la colonoscopia, y las no invasivas, como los ensayos de laboratorio y la imagenología. Esta revisión, se centrará exclusivamente en las pruebas de tamizaje no invasivas que utilizan muestras de deposiciones, excluyendo las imágenes. Se abordarán las últimas recomendaciones internacionales sobre el momento etario en que se deben utilizar, sus bases técnico-biológicas, los dos principales tipos utilizados en la actualidad (bioquímico e inmunológico) y pondremos en perspectiva sus ventajas y posibles desventajas. Al final de esta revisión, se discutirá brevemente los últimos avances biotecnológicos relacionados con pruebas moleculares basadas en el estudio de muestras sanguíneas. Aunque estas pruebas aún no son de uso clínico habitual debido a sus altos costos, representan una prometedora innovación para la detección temprana del CCR.

ABSTRACT

Introduction: there is a great diversity in the profile of cancers in the world. This study set out to analyze the profile of gynecological cancer in Federal University Teaching Hospital, Owerri, [FUTHO] (former Federal Medical Centre, Owerri, Imo state, Nigeria). Methods: this was a retrospective cross sectional descriptive study of the records of women admitted in the gynecological ward in FUTHO from January 2020 to November 2022. It was analyzed using SPSS version 23.0 and reported in simple percentages for categorical variables and measures of central tendency for quantitative variables. Results: a total of 1,378 gynecological patients were admitted into the Gynaecological ward of the hospital, out of which 242 (17.6%) were cancer cases. The most common cancer over the three years in review, was ovarian, 81(33.5%), followed by cervical, 66 (27.3 %), endometrial, 65 (26.8 %), choriocarcinoma, 22 (9.1%), vulvar, 6 (2.5%) and vagina, 2(0.8%). The most common gynecological cancers in this study is very different from previous reports from Nigeria and other African countries. The pattern looks like that seen in the developed countries where endometrial and ovarian cancers top the list. Conclusion: this report shows a possible change in lifestyle and improved access to cervical cancer prevention strategies. It is also assumed that all the facilities who have recorded cervical cancer as the most common cancer can actually have a similar result as ours if a more current review is done.

ABSTRACT

Objetivos: revisar os estudos clínicos acerca de biomarcadores para o câncer cervical publicados nos últimos 10 anos, com foco no diagnóstico, prognóstico e avaliação do tratamento. Metodologia: as bases de dados PubMed, Web of Science e Science Direct foram pesquisadas utilizando os descritores "Uterine Cervical Neoplasms" e "Biomarkers". Foram selecionados os artigos originais publicados em inglês ou português, no período de 2011 a 2021. Após uma triagem pelos títulos e resumos dos artigos, aqueles relacionados ao objetivo do estudo foram lidos integralmente para a decisão final de inclusão na revisão. Os trabalhos que atenderam todos os critérios de seleção tiveram seus dados extraídos, principalmente, no que se refere ao tipo e objetivo do biomarcador proposto, população do estudo, tamanho da amostra, metodologia utilizada e principais desfechos obtidos. Resultados: esta estratégia de busca e seleção resultou em 22 artigos publicados nos últimos 10 anos na temática de interesse. Ocorreu um grande empenho na investigação de biomarcadores séricos para o câncer cervical, com a vantagem de serem minimamente invasivos. Houve destaque para marcadores genéticos e moleculares, como aqueles voltados para a metilação do DNA, detecção de polimorfismos, padrões de expressão de micro-RNA e expressão de genes relacionados à proliferação, imortalização e invasão celular. Conclusão: os dados reunidos encorajam a ampliação das pesquisas para aprimorar e validar a eficiência destes biomarcadores em grandes populações. É evidente o potencial dos biomarcadores como estratégia para melhorar o manejo do diagnóstico e o tratamento do câncer cervical, sendo que a utilização de marcadores genéticos parece ser o futuro dos biomarcadores para o câncer cervical


Aims: to review clinical studies on biomarkers for cervical cancer published in the last 10 years, focusing on the diagnosis, prognosis, and treatment evaluation. Methods: PubMed, Web of Science, and Science Direct databases were searched using the descriptors "Uterine Cervical Neoplasms" and "Biomarkers". Original articles published in English or Portuguese from 2011 to 2021 were selected. After screening by the titles and abstracts of the articles, those related to the objective of the study were read in full for the final decision of inclusion in the review. The studies that met all the selection criteria had their data extracted, especially regarding the type and objective of the biomarker proposed, study population, sample size, methodology used, and main outcomes obtained. Results: this search and selection strategy resulted in 22 articles published in the last 10 years on the topic of interest. There was a great effort to investigate serum biomarkers for cervical cancer, with the advantage of being minimally invasive. There was an emphasis on genetic and molecular markers, such as those focused on DNA methylation, detection of polymorphisms, expression patterns of microRNA, and expression of genes related to cell proliferation, immortalization, and invasion.Conclusions: the data gathered encourage expanded research to improve and validate the efficiency of these biomarkers in large populations. The potential of biomarkers as a strategy to improve the management of cervical cancer diagnosis and treatment is evident, and the use of genetic markers appears to be the future of biomarkers for cervical cancer

ABSTRACT

BACKGROUND@#Lung cancer is one of the most common malignant tumors in the world, and the current lung cancer screening and treatment strategies are constantly improving, but its 5-year survival rate is still very low, which seriously endangers human health. Therefore, it is critical to explore new biomarkers to provide personalized treatment and improve the prognosis. Cuproptosis is a newly discovered type of cell death, which is due to the accumulation of excess copper ions in the cell, eventually leading to cell death, which has been suggested by studies to be closely related to the occurrence and development of lung adenocarcinoma (LUAD). Based on The Cancer Genome Atlas (TCGA) database, this study explored the association between cuproptosis-related genes (CRGs) and LUAD prognosis, established a prognostic risk model, and analyzed the interaction between CRGs and LUAD immune cell infiltration.@*METHODS@#The RNA-seq data of LUAD tissue and paracancerous or normal lung tissue were downloaded from the TCGA database; the RNA-seq data of normal lung tissue was downloaded from the Genotype-tissue Expression (GTEx) database, and the data of 462 lung adenocarcinoma cases were downloaded from the Gene Expression Omnibus repository (GEO) as verification. T the risk score model to assess prognosis was constructed by univariate Cox and Lasso-Cox regression analysis, and the predictive ability of the model was evaluated by receiver operating characteristic (ROC) curve and calibration curve. Immune-related and drug susceptibility analysis was further performed on high- and low-risk groups.@*RESULTS@#A total of 1656 CRGs and 1356 differentially expressed CRGs were obtained, and 13 CRGs were screened out based on univariate Cox and Lasso-Cox regression analysis to construct a prognostic risk model, and the area under the curves (AUCs) of ROC curves 1-, 3- and 5- year were 0.749, 0.740 and 0.689, respectively. Further study of immune-related functions and immune checkpoint differential analysis between high- and low-risk groups was done. High-risk groups were more sensitive to drugs such as Savolitinib, Palbociclib, and Cytarabine and were more likely to benefit from immunotherapy.@*CONCLUSIONS@#The risk model constructed based on 13 CRGs has good prognostic value, which can assist LUAD patients in individualized treatment, and provides an important theoretical basis for the treatment and prognosis of LUAD.

ABSTRACT

Using prostate-specific antigen (PSA) for prostate cancer (PCa) screening led to overinvestigation and overdiagnosis of indolent PCa. We aimed to investigate the value of prostate health index (PHI) and magnetic resonance imaging (MRI) prostate in an Asian PCa screening program. Men aged 50-75 years were prospectively recruited from a community-based PSA screening program. Men with PSA 4.0-10.0 ng ml -1 had PHI result analyzed. MRI prostate was offered to men with PSA 4.0-50.0 ng ml -1 . A systematic prostate biopsy was offered to men with PSA 4.0-9.9 ng ml -1 and PHI ≥35, or PSA 10.0-50.0 ng ml -1 . Additional targeted prostate biopsy was offered if they had PI-RADS score ≥3. Clinically significant PCa (csPCa) was defined as the International Society of Urological Pathology (ISUP) grade group (GG) ≥2 or ISUP GG 1 with involvement of ≥30% of total systematic cores. In total, 12.8% (196/1536) men had PSA ≥4.0 ng ml -1 . Among 194 men with PSA 4.0-50.0 ng ml -1 , 187 (96.4%) received MRI prostate. Among them, 28.3% (53/187) had PI-RADS ≥3 lesions. Moreover, 7.0% (107/1536) men were indicated for biopsy and 94.4% (101/107) men received biopsy. Among the men received biopsy, PCa, ISUP GG ≥2 PCa, and csPCa was diagnosed in 42 (41.6%), 24 (23.8%), and 34 (33.7%) men, respectively. Compared with PSA/PHI pathway in men with PSA 4.0-50.0 ng ml -1 , additional MRI increased diagnoses of PCa, ISUP GG ≥2 PCa, and csPCa by 21.2% (from 33 to 40), 22.2% (from 18 to 22), and 18.5% (from 27 to 32), respectively. The benefit of additional MRI was only observed in PSA 4.0-10.0 ng ml -1 , and the number of MRI needed to diagnose one additional ISUP GG ≥2 PCa was 20 in PHI ≥35 and 94 in PHI <35. Among them, 45.4% (89/196) men with PSA ≥4.0 ng ml -1 avoided unnecessary biopsy with the use of PHI and MRI. A screening algorithm with PSA, PHI, and MRI could effectively diagnose csPCa while reducing unnecessary biopsies. The benefit of MRI prostate was mainly observed in PSA 4.0-9.9 ng ml -1 and PHI ≥35 group. PHI was an important risk stratification step for PCa screening.

ABSTRACT

Objective: To explore the utility of stool-based DNA test of methylated SDC2 (mSDC2) for colorectal cancer (CRC) screening in residents of Shipai Town, Dongguan City. Methods: This was a cross-sectional study. Using a cluster sampling method, residents of 18 villages in Shipai Town, Dongguan City were screened for CRC from May 2021 to February 2022. In this study, mSDC2 testing was employed as a preliminary screening method. Colonoscopy examination was recommended for individuals identified as high-risk based on the positive mSDC2 tests. The final screening results, including the rate of positive mSDC2 tests, the rate of colonoscopy compliance, the rate of lesions detection, and the cost-effectiveness of screening, were analyzed to explore the benefits of this screening strategy. Results: A total of 10 708 residents were enrolled and completed mSDC2 testing, giving a participation rate of 54.99% (10 708/19 474) and a pass rate of 97.87% (10 708/10 941). These individuals included 4 713 men (44.01%) and 5 995 women (55.99%) with a mean age of (54.52±9.64) years. The participants were allocated to four age groups (40-49, 50-59, 60-69, and 70-74 years), comprising 35.21%(3770/10 708), 36.25% (3882/10 708), 18.84% (2017/10 708), and 9.70% (1039/10 708) of all participants, respectively. mSDC2 testing was positive in 821/10 708 (7.67%) participants, 521 of whom underwent colonoscopy, resulting in a compliance rate of 63.46% (521/821). After eliminating of 8 individuals without pathology results, data from 513 individuals were finally analyzed. Colonoscopy detection rate differed significantly between age groups (χ2=23.155, P<0.001),ranging from a low of 60.74% in the 40-49 year age group to a high of 86.11% in the 70-74 year age group. Colonoscopies resulted in the diagnosis of 25 (4.87%) CRCs, 192 (37.43%) advanced adenomas, 67 (13.06%) early adenomas, 15 (2.92%) serrated polyps, and 86 (16.76%) non- adenomatous polyps. The 25 CRCs were Stage 0 in 14 (56.0%) individuals, stage I in 4 (16.0%), and Stage II in 7(28.0%). Thus, 18 of the detected CRCs were at an early stage. The early detection rate of CRCs and advanced adenomas was 96.77% (210/217). The rate of mSDC2 testing for all intestinal lesions was 75.05% (385/513). In particular, the financial benefit of this screening was 32.64 million yuan, and the benefit-cost ratio was 6.0. Conclusion: Screening for CRCs using stool-based mSDC2 testing combined with colonoscopy has a high lesion detection rate and a high cost-effectiveness ratio. This is a CRC screening strategy that deserves to be promoted in China.
