Knowledge, attitudes, and practices in colorectal cancer screening in the Philippines

Background and Objective@#Colorectal cancer (CRC) has the third highest incidence in the Philippines. Currently, there is a paucity in literature that is focused on the knowledge, attitudes, and perceptions of Filipinos regarding CRC screening. This is the first study in the Philippines that describes this. @*Methods@#This is a cross-sectional study that validated a 52-item Filipino questionnaire on the knowledge on colorectal cancer, willingness to undergo CRC screening, and perceived benefits and barriers to fecal occult blood test (FOBT) and colonoscopy. The study enrolled household heads more than 20 years of age residing in both urban and rural communities in the Philippines. @*Results@#The UP-PGH CRC KAP (University of the Philippines – Philippine General Hospital Colorectal Cancer Knowledge, Attitudes, and Practices) and Rawl Questionnaire’s validity and internal consistency were established in a pilot study of 30 respondents. A total of 288 respondents were then enrolled to the main study group with a median age of 54.0. Knowledge scores for prognosis and utility of CRC screening were modest (6.3/12 and 8.4/20, respectively). Perceived benefit scores to FOBT and colonoscopy were high (9.9/12 and 13.9/16, respectively).Median scores to barriers to FOBT and colonoscopy were intermediate (22.5/36 and 35.8/60, respectively). Notably, a vast majority (86.1%) were willing to participate in CRC screening programs initiated by the government, and 46.9% agreed to undergo screening tests even as out-of-pocket expense. @*Conclusion@#The UP-PGH CRC KAP Questionnaire as well as the Filipino translation of the Rawl Questionnaire are reliable and valid tools in extensively assessing the knowledge of Filipinos on CRC and willingness to undergo screening, as well as the benefits of and barriers to FOBT and colonoscopy. Knowledge scores were modest suggesting that directed educational campaigns and awareness programs can aid in increasing awareness about CRC and its screening. Household income and highest educational attainment were significantly positively correlated with knowledge scores, and perceived benefits of and barriers to CRC screening. Scores were generally comparable between urban and rural communities.

Percepção de mulheres residentes em Barreiras (BA) quanto ao rastreamento do câncer de colo do útero / Perception of women living in Barreiras regarding cervical cancer screening / Percepción de las mujeres residentes en Barreiras, Bahía, sobre el cribado de cáncer del cuello uterino

O rastreamento do câncer de colo do útero (CCU) é uma das estratégias para diminuição da incidência e morbimortalidade dessa neoplasia. Portanto, é necessário estudar os fatores que estão associados à sua realização. Este estudo visa analisar a adesão ao rastreamento do CCU na cidade de Barreiras (BA), com vistas às ações de educação em saúde e ao papel dos profissionais de saúde nessa prevenção. A abordagem da pesquisa foi descritiva qualitativa, com utilização de questionário. Os dados coletados foram organizados pelo software Excel 2016. Na análise inferencial, foi utilizado o software GraphPad Prism 5.0 e o teste de Spearman. A maioria da amostra (37%) tem entre 30 e 40 anos e possui ensino médio completo (65%). Ademais, 71% consideram realizar regularmente o preventivo. A maior parcela iniciou o Papanicolau antes dos 20 anos, principalmente devido ao aconselhamento do profissional de saúde (58%). Constatou-se correlação positiva entre frequência e presença de educação em saúde na Unidade Básica de Saúde (r = 0,2982; p = 0,0122); e entre realização do exame regular e incentivo pelo profissional de saúde (r = 0,4284; p = 0,0015). Conclui-se que a maioria das questionadas possuía conhecimento prévio a respeito do preventivo, sendo importante ressaltar a educação em saúde e o incentivo do profissional como fundamentais para essa adesão.

Prevalência de pólipos serrilhados e sua associação com adenomas avançados colorretais síncronos / Prevalence of serrated polyps and their association with synchronous colorectal advanced adenomas

ABSTRACT Background: Serrated lesions are the precursors of up to one-third of colorectal cancer (CRC) cases and share molecular and epidemiological features with interval CRC. Previous studies have reported wide variation in serrated polyp prevalence and diverse magnitude of its relationship with synchronous advanced adenomas. Objective: Describe the prevalence of serrated polyps and evaluate their association with synchronous advanced adenomas. Methods: The study is a retrospective analysis of 1208 colonoscopies performed in patients aged 45 to 75, predominantly for CRC screening. Data on the prevalence of serrated polyps subsets and advanced adenomas were collected, and multivariate analysis were performed to identify the association between serrated polyps and synchronous advanced adenomas. Results: The prevalence of clinically significant serrated polyps (CSSP), large serrated polyps (LSP), and sessile serrated adenomas (SSA) were 11.3%, 6%, and 3.7%. CSSP were associated with synchronous advanced adenomas (OR 2.121, 95%CI 1.321-3.406), regardless of proximal (OR 2.966, 95%CI 1.701-5.170) or distal (OR 1.945, 95%CI 1.081-3.499) location, while LSP (OR 2.872, 95%CI 1.425-5.787) and SSA (OR 5.032, 95%CI 2.395-10.576) were associated with proximal advanced adenomas. Conclusion: The prevalence of CSSP and advanced adenomas were alike. CSSP is a risk factor for advanced adenomas, and the strength of this association is stronger for proximal advanced adenomas. LSP and SSA are associated with proximal advanced adenomas.

RESUMO Contexto: Lesões serrilhadas são precursoras de até um terço dos casos de câncer colorretal (CCR) e compartilham características moleculares e epidemiológicas com o CCR de intervalo. Estudos prévios relataram ampla variação na prevalência de pólipos serrilhados e na magnitude da sua relação com adenomas avançados sincrônicos. Objetivo: Descrever a prevalência de pólipos serrilhados colorretais e avaliar sua associação com adenomas avançados sincrônicos. Métodos: O estudo é uma análise retrospectiva de 1208 colonoscopias realizadas em pacientes com idades entre 45 e 75 anos, predominantemente para rastreamento de CCR. Dados sobre a prevalência de subtipos de pólipos serrilhados e de adenomas avançados foram coletados, e análises multivariadas foram realizadas para identificar a associação entre pólipos serrilhados e adenomas avançados sincrônicos. Resultados: A prevalência de pólipos serrilhados clinicamente significativos (PSCS), pólipos serrilhados grandes (PSG) e adenomas sésseis serrilhados (ASS) foi de 11,3%, 6% e 3,7%, respectivamente. PSCS foram associados a adenomas avançados sincrônicos (OR 2,121, IC95% 1,321-3,406), independentemente da localização proximal (OR 2,966, IC95% 1,701-5,170) ou distal (OR 1,945, IC95% 1,081-3,499), enquanto PSG (OR 2,872, IC 95%1,425-5,787) e ASS (OR 5,032, IC95% 2,395-10,576) foram associados a adenomas avançados proximais. Conclusão: A prevalência de PSCS e de adenomas avançados foi semelhante. PSCS é um fator de risco para adenomas avançados, e a força dessa associação é maior para adenomas avançados proximais. PSG e ASS estão associados a adenomas avançados proximais.

Atitudes e crenças de médicos ginecologistas- -obstetras e de pacientes do Hospital Universitário de Brasília sobre o rastreamento cervical e o exame pélvico / Attitudes and beliefs of obstetrician-gynecologists and patients at the University Hospital of Brasília about cervical screening and pelvic examination

Objetivo: Avaliar as atitudes e crenças de pacientes e médicos ginecologistas-obstetras sobre o rastreamento cervical e o exame pélvico no Hospital Universitário de Brasília (HUB). Métodos: Foram realizadas entrevistas com pacientes que aguardavam por uma consulta previamente agendada no ambulatório de ginecologia e com médicos ginecologistas-obstetras que atuavam no HUB. Cada grupo respondeu a um questionário que enfocava a realização do rastreamento cervical e do exame pélvico (EP). Resultados: No total, 387 pacientes responderam ao questionário. Dessas, apenas 4,13% sabiam que, de acordo com as diretrizes brasileiras, o rastreamento cervical deveria ser iniciado aos 25 anos de idade, 5,17% sabiam que ele deveria ser encerrado aos 64 anos e 97,93% esperavam um intervalo menor do que o trienal recomendado. Após serem informadas sobre as diretrizes, 66,93% acreditavam que o início aos 25 anos é tardio, 61,5%, que o encerramento aos 64 anos é precoce, 88,37%, que o intervalo trienal é muito longo e 94,06% ficaram com receio de que problemas de saúde pudessem aparecer nesse intervalo. Dos 44 médicos que responderam ao questionário, embora a maioria concordasse com as diretrizes, somente 31,82%, 38,64% e 34,1% as seguia com relação à frequência, à idade de início e à idade de encerramento, respectivamente. Quanto ao EP, aproximadamente metade dos participantes de cada grupo considerava que o exame deveria ser realizado nas consultas regulares com o ginecologista. Conclusão: Foi observada uma discrepância entre as expectativas das pacientes e as diretrizes para o rastreamento de câncer cervical. A maior parte das pacientes não as conhecia e, quando informadas, não concordava com elas. Quanto aos médicos ginecologistas- obstetras, a maioria não as seguia, apesar de conhecê-las. Quanto ao EP, grande parte dos médicos e pacientes considerava-o importante e acreditava que ele deveria ser realizado de forma rotineira nas consultas ginecológicas.

Objective: Evaluate the attitudes and beliefs of patients and obstetrician-gynecologists about cervical screening and pelvic examination in the University Hospital of Brasília (HUB). Methods: Face-to-face interviews with patients waiting for a previously scheduled consultation at the gynecology outpatient clinics and attending obstetrician-gynecologists at the HUB. Each group answered a questionnaire addressing cervical screening and pelvic examination (PE). Results: 387 patients answered the questionnaire. Of these, only 4.13% were aware that, according to Brazilian guidelines, cervical screening should begin at age 25, 5.17% that it should stop at age 64 and 97.93% expected a shorter interval than the recommended triennial. After being informed of the guidelines, 66.93% believed that starting at age 25 is late, 61.5% that stopping at 64 is early, 88.37% that the triennial interval is too long, and 94.06% would be afraid that health problems could appear during the interval. Of the 44 participating physicians, although most agreed with the guidelines, only 31.82%, 38.64% and 34.1% followed them regarding frequency, starting and stopping age, respectively. As for EP, approximately half of the participants in each group believed that it should be performed in regular consultations with the gynecologist. Conclusion: There was a discrepancy between patients' expectations and cervical screening guidelines. Most patients didn't know and, when informed, didn't agree with them. As for Ob-Gyn physicians, most did not follow these guidelines, despite knowing them. As for pelvic exam, most physicians and patients considered it important and believed it should be routinely performed during gynecological consultations.

Cervical cancer screening and early diagnosis / 中国医师杂志

Among female malignant tumors, cervical cancer ranks fourth in terms of incidence rate and mortality. To accelerate the elimination of cervical cancer, increasing the vaccination rate of human papillomavirus (HPV) and cervical cancer screening are the most important methods. In recent years, the incidence of cervical cancer in China has shown a younger trend, and the population screening rate is low. Scientific and extensive cervical cancer screening and early diagnosis are crucial. The screening strategies for cervical cancer in various countries around the world have certain differences and are constantly updated in terms of methods, start time, time interval, and end time. Starting from the etiology and epidemiology of cervical cancer, this article summarizes the latest cervical cancer screening methods, strategies, and early diagnosis experience at home and abroad, providing help and thinking for the prevention and treatment of cervical cancer.

High-risk human papillomavirus negative cervical lesions in the cervical cancer screening population / 中国医师杂志

Objective:To investigate the incidence of high-risk human papillomavirus (hrHPV) negative cervical lesions in the screening population, and based on this, to preliminarily evaluate the potential harm (missed diagnosis) and benefits (reduced colposcopy referral) of HPV primary screening compared to combined screening so as to provide reference for the selection of cervical cancer primary screening methods.Methods:This study was a single center cross-sectional study. Women who underwent joint screening [hrHPV typing test combined with cervical liquid based cytology test (LCT)] at the Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from January 1, 2018 to December 31, 2019 were included in the cervical cancer screening. The proportion of hrHPV negative cytological abnormalities and cervical lesions in the population was analyzed and the theoretical colposcopy referral rate of the combined screening and HPV initial screening protocol was calculated. In the population with cervical pathological results, the number of colposcopy examinations required for the diagnosis of cervical intraepithelial neoplasia grade 2 and above (CIN2+ ) was calculated.Results:A total of 35 321 screened women were included. The overall incidence of hrHPV infection, LCT abnormalities and severe LCT abnormalities in the population was 17.13%(6 051/35 321), 18.07%(6 384/35 321), and 3.97%(1 402/35 321), respectively. The negative rate of hrHPV in women with severe cervical cytology abnormalities was as high as 51.28%(719/1 402), and in CIN2+ lesions diagnosed by cervical biopsy, hrHPV negative accounted for 7.15% (49/685). The theoretical colposcopy referral rates for combined screening and initial HPV screening were 11.28%(3 985/35 321) and 8.33%(2 943/35 321), respectively, with an average diagnosis of CIN2+ requiring 3.51 and 2.81 colposcopy examinations, respectively.Conclusions:In the opportunistic screening population, the proportion of hrHPV negative CIN2+ lesions cannot be ignored, and the HPV initial screening strategy may cause missed diagnosis of these lesions. However, compared to combined screening, HPV initial screening has the potential to improve the efficiency of colposcopy. These results suggest that we should carefully choose the HPV initial screening plan.

Screening for cervical cancer and diversion of abnormal screening results / 中国医师杂志

Cervical cancer is still a serious threat to the health of women in China. The current strategy is a three-level prevention strategy, among which the diversion of screening and screening abnormalities in the secondary prevention is an important link in preventing cervical cancer. For more than 20 years, China has implemented diversified screening methods such as cytological examination, high-risk human papillomavirus (HPV) testing, and naked eye screening. With the discovery that high-risk HPV infection is closely related to the occurrence of cervical cancer, the screening method for cervical cancer has shifted from cytological examination to HPV testing as the preferred screening method. This article introduces the advantages and disadvantages of high-risk HPV testing and cytological examination as screening methods, and proposes the issues that need to be paid attention to in screening; The principle of diverting screening abnormalities was proposed, and it was proposed that in the process of diverting, individualized and refined management principles should be implemented for screening abnormality projects based on the patient′s age and fertility requirements.

Application of DNA methylation markers in the whole process management of cervical lesions / 中国医师杂志

DNA methylation plays an important role in the occurrence and development of cervical cancer. DNA methylation detection can be combined or complemented with human papillomavirus (HPV), cytology, etc., which is helpful to improve the accuracy of cervical cancer screening or reduce the rate of colposcopy referral. In this review, we focus on the significance of DNA methylation markers in cervical cancer screening and overall management.

Challenges in screening and early detection of gynecologic malignancies / 中国医师杂志

Screening and early diagnosis are the key means to reduce the incidence rate and mortality of cancer. This article aims to briefly summarize the current status and challenges of screening and early diagnosis of three common female reproductive tract malignancies (cervical cancer, endometrial cancer, and ovarian cancer), in order to clarify the current stage and future direction of efforts.

Willingness and influencing factors for cervical cancer screening among women in Chizhou / 公共卫生与预防医学

Objective To investigate the influencing factors of willingness to screen for cervical cancer in women in Chizhou. Methods A cross-sectional web-based survey of 3,058 migrant women living in Chizhou was conducted through a social media platform. The survey included questionnaires on socioeconomic characteristics, history of cervical cancer screening, knowledge of cervical cancer prevention and treatment, and attitude. The χ2 test and logistic regression were used to analyze the influencing factors of willingness to screen. Results Under 60 years of age, having a spouse or sexual partner (OR=1.368), having a junior high school education or above, living in urban areas (OR = 1.501), local household registration (OR=1.363), high monthly income, and high knowledge of cervical cancer prevention and control (OR=1.198) were positively associated with the rate of willingness to undergo cervical screening. Among attitude barriers, there were statistically significant differences in fear of seeing male doctors (38.23%), fear of seeing poor results (31.92%), belief that screening was painful (23.56%), shyness or embarrassment (20.18%), and belief that they did not need to participate in screening due to asymptomatic (17.56%), having received HPV vaccine (15.86%), or ages at which screening was not considered necessary (15.14%) between the groups (P<0.05). Conclusion Socioeconomic characteristics, knowledge of prevention and treatment, fear of screening experience, and lack of motivation are related factors affecting cervical cancer screening willingness. Achieving cervical cancer elimination requires action to improve screening coverage in socio-economic, health education and women's attitudes.

Gastric cancer risk assessment based on serum pepsinogen / Монголын Анагаах Ухаан

Introduction@#Cases of gastric cancer have been declining worldwide in recent years. However, gastric cancer incidence increased in the last decade in Mongolia. In Mongolia, over 80% of gastric cancer cases are diagnosed during the late stage. Several studies have revealed that serum pepsinogens (PGs) level reflects, indirectly, histological and functional characteristics of the gastric mucosa.@*Goal@#We aimed to evaluate the risk of gastric cancer and its precancerous condition based on serum PGI, PGI/II biomarkers.@*Materials and Methods@#This case-control study enrolled 114 subjects, including patients with gastric cancer (n=36), atrophic gastritis (n=40) and healthy controls (n=138). The questionnaires were obtained to determine risk factors. Serum PGI, PGII, and H. pylori IgG levels were measured by ELISA (Pepsinogen I ELISA; Pepsinogen II ELISA; H.Pylori IgG ELISA; BIOHIT Plc, Helsinki, Finland). PGI to PGII ratio was calculated. Patients were classified into the ABC(D) group according to Miki K approach. Also, we developed new scoring system based on some risk factors and serum PGI, PGI/II ratio. Logistic regressions were performed to evaluate risk and expressed by odds ratio (OR) and 95% confidence intervals (95%CI).@*Results@#Mean age of the subjects was 60±10.9 years. H.Pylori was positive in 67 subjects. The serum PGI and PGI/II ratio levels were significantly decreased in gastric cancer and atrophic gastritis groups compared to the healthy control. According to classification ABC(D), group D (OR 5.04, 95% CI 1.13-22.50) had higher proportion of atrophic gastritis cases, group C (OR 6.19, 95% CI 1.04-36.78) had higher proportion of gastric cancer cases than others. Additionally, we created a risk prediction scoring system with a score ranging from 0 to 7, based on variables age, family history of gastric cancer, prior disease history, PGI and PGI/II ratio levels. For the atrophic gastritis patients, 17 (42.5%) were classified into medium-risk category (OR 4.49, 95% CI 1.38-14.58) and 17 (42.5%) were classified into high-risk category (OR 7.69, 95% CI 2.16-27.43). Whereas, 11 (30.6%) patients with gastric cancer were classified into medium-risk category (OR 4.35, 95% CI 1.13-16.85), 21 (58.3%) were classified into high-risk category (OR 14.25, 95% CI 3.60-56.43).@*Conclusion@#The methods based on serum PGI and PGI/II may identify a high risk population of gastric cancer and atrophic gastritis.

Recommendations of the Brazilian College of Radiology, the Brazilian Society of Mastology and the Brazilian Federation of Gynecology and Obstetrics Associations for breast cancer screening in Brazil

Objective: To present the updated recommendations of the Brazilian College of Radiology and Imaging Diagnosis, the Brazilian Society of Mastology and the Brazilian Federation of Gynecology and Obstetrics Associations for breast cancer screening in Brazil. Methods: Between January 2012 and July 2022, searches for scientific evidence published in MEDLINE, Embase, Cochrane Library, EBSCO, CINAHL and LILACS were carried out. The recommendations were based on this evidence, with the consensus of a committee of experts from the three institutions. Recommendations: The annual mammography screening is recommended for normal-risk patients aged between 40 and 74 years. For women aged more than 75 years, it is reserved for those whose life expectancy is longer than seven years. Women whose risk is higher than normal, such as those with dense breasts, personal history of atypical lobular hyperplasia, classic in situ lobular carcinoma, atypical ductal hyperplasia, women undergoing breast cancer treatment or thoracic irradiation before the age of 30, or those with genetic mutation or strong family history, benefit from complementary screening, being considered in an individual manner. Tomosynthesis is an evolution of mammography and should be considered in screening whenever accessible and available

Cervical Cancer Screening with DNA-HPV Testing and Precancerous Lesions Detection: A Brazilian Population-based Demonstration Study / Rastreamento do câncer do colo do útero com teste de DNA-HPV e detecção de lesões precursoras: um estudo de demonstração de base populacional brasileiro

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.

Análise de custo-efetividade do rastreamento com tomografia computadorizada de baixa dose para detecção precoce de câncer de pulmão sob a perspectiva do Sistema Único de Saúde / Cost-effectiveness analysis of low-dose computed tomography screening for early detection of lung cancer from the perspective of the Unified Health System

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.

Determining the relationship between serum acute phase reactants and cervical premalignant lesions: a cohort study

Abstract BACKGROUND: Acute phase reactants play a role in the progression and prognosis of many malignant and premalignant tumors. This study investigated the diagnostic value of certain reactants as markers for cervical premalignant lesions. OBJECTIVES: Despite advanced screening and vaccination programs, cervical cancer remains a serious health problem worldwide. We aimed to determine the possible relationship between premalignant cervical disease and serum acute phase reactant levels. DESIGN AND SETTING: This study included 124 volunteers who underwent cervical cancer screening. We divided the patients into three groups according to cervical cytology and histopathological findings as follows: no cervical lesion, low-grade neoplasia, or high-grade neoplasia. METHODS: We included women aged 25-65 years with benign smear or colposcopy results, low- and high-grade squamous intraepithelial lesions. The benign group was based only on cytology findings, whereas the other groups were based on histopathology findings. Demographic data and serum albumin, fibrinogen, ferritin, and procalcitonin levels were evaluated in the three groups. RESULTS: We found significant differences among the three groups in terms of age, albumin level, albumin/fibrinogen ratio, and procalcitonin level. The regression analysis revealed lower serum albumin levels in the low- and high-grade squamous intraepithelial lesion groups compared with the benign group. CONCLUSION: This is the first study to evaluate the importance of serum inflammatory markers in cervical intraepithelial lesions. Our results indicate that serum albumin level, albumin/fibrinogen ratio, procalcitonin level, and neutrophil values differ among cervical intraepithelial lesions.

Evaluation of clinical, pathological and epidemiological profile of patients with breast cancer in the microregion of Lavras ­ MG

Breast cancer is associated with high frequency and mortality in Brazilian women. There have been limited studies portraying the characteristics of breast cancer cases in the countryside of the state of Minas Gerais for a long period of time, a fact that will allow us to better understand the epidemiology of these tumors. This descriptive study aims to analyze the epidemiology and clinical features of patients with breast cancer treated at a public health service facility in Lavras, MG. Methods: This is a transversal study with 299 women diagnosed with breast cancer between 2002 and 2022, based on data collection from medical records and subsequent descriptive analysis. Results: There were a total of 317 cases, and 299 were eligible for the study. The mean age at diagnosis was 54.2 years, and 36.1% of the patients were under 50 years old at diagnosis. Positive family history was found in 17.0% of the patients. The diagnosis was made by clinical alteration detected on physical examination in 71.5% of cases, and lump was the most frequent type of lesion (89.0%). Invasive carcinoma was 93.1% of the cases, and the mean tumor size was 28.6 mm. The average time between first medical appointment and diagnosis was 63.2 days, and between diagnosis and beginning of treatment was 39.6 days. Conclusions: This study showed that a significant number of cases occurred in women outside the recommended age for screening in Brazil. Diagnosis was predominantly performed by clinical examination, with delays in obtaining the histological diagnosis, and the stage at diagnosis was high, and these facts were associated with the health system limitations (AU)

Recommendations for the Screening of Breast Cancer of the Brazilian College of Radiology and Diagnostic Imaging, Brazilian Society of Mastology and Brazilian Federation of Gynecology and Obstetrics Association / Recomendações para o rastreio do câncer de mama do colégio brasileiro de radiologia e diagnóstico por imagem, sociedade brasileira de mastologia e associação da federação brasileira de ginecologia e obstetrícia

Abstract Objective To present the update of the recommendations of the Brazilian College of Radiology and Diagnostic Imaging, the Brazilian Society of Mastology and the Brazilian Federation of Associations of Gynecology and Obstetrics for breast cancer screening in Brazil. Methods Scientific evidence published in Medline, EMBASE, Cochrane Library, EBSCO, CINAHL and Lilacs databases between January 2012 and July 2022 was searched. Recommendations were based on this evidence by consensus of the expert committee of the three entities. Recommendations Annual mammography screening is recommended for women at usual risk aged 40-74 years. Above 75 years, it should be reserved for those with a life expectancy greater than seven years. Women at higher than usual risk, including those with dense breasts, with a personal history of atypical lobular hyperplasia, classic lobular carcinoma in situ, atypical ductal hyperplasia, treatment for breast cancer or chest irradiation before age 30, or even, carriers of a genetic mutation or with a strong family history, benefit from complementary screening, and should be considered individually. Tomosynthesis is a form of mammography and should be considered in screening whenever accessible and available.

Knowledge of cervical cancer among women of reproductive age in Ibadan north lga, Oyo State, Nigeria

Nigeria has one of the highest rates of cervical cancer morbidity and mortality in Sub-Saharan Africa. Both the human papillomavirus vaccine (HPV) and cervical screening are effective prevention strategies against both HPV infection and cervical cancer. Lack of awareness, limited knowledge, limited decision-making agency, lack of spousal support and stigma are barriers to uptake of these preventive measures. Cervical cancer is a deadly disease claiming the lives of many women in developing countries due to late presentation which might be influenced by a lack of knowledge of the disease and its prevention. Method: This descriptive study examined the knowledge assessment of cervical cancer among women of reproductive age (15-49), about cervical cancer, its prevention, and their utilization of Pap smear screening; using a convenience sample of 426 women in Ibadan North Local Government Area of Oyo State, Nigeria. Women voluntarily completed a structured questionnaire. Result: Results showed that women who participated in the study were aware of cervical cancer (77%; n=328) but many (62.9%; n= 268) were unaware of Pap smears as the screening tests for cervical cancer. Although 41.3% (n=176) were knowledgeable about cervical cancer, risk factors and prevention, only 9.4% (n=40) had Pap smear tests done. Conclusion: Health care professionals, need to intensify efforts to increase awareness about cervical cancer screening, and encourage women through the different clinics to use these services. The benefits of screening and early diagnosis of cervical cancer should be emphasized to enhance the utilization of cervical cancer screening services.

Exploring prostate cancer screening among men in Accra using the health belief model

Objective: To explore the prevalence of prostate cancer screening among Ghanaian men and interrogate why some individuals screen for the disease and others do not. Design: A cross-sectional questionnaire survey based on the Health Belief Model was used to collect data from 356 men aged 40 years and above. Data were collected between February and March 2021. Setting: The study was conducted in the Accra metropolitan area of the Greater Accra region of Ghana. Participants: Convenience sampling was used to recruit participants for the study. Results: Although 86% of the respondents had heard about prostate cancer, only 23% had ever screened for it. Logistic regression analysis suggested that knowledge of the disease (OR = 1.19, CI 95% = 1.03 -1.38) and barriers to screening (OR = .87, CI 95% = .83 -.91) were statistically significant predictors of screening behaviour. Conclusion: HBM has limited predictive power as far as our study is concerned. We suggest increasing public education on prostate cancer and its screening methods. The cost of screening should also be made more affordable so as not to become a barrier.
