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.

Evaluation of the effectiveness of qualitative and quantitative fecal immunochemical tests in colorectal cancer screening / 预防医学

Objective@#To compare the effectiveness of qualitative and quantitative fecal immunochemical tests (FIT) in identifying colorectal cancer, so as to provide insights into perfecting screening strategies for colorectal cancer.@*Methods@#Participants in the Colorectal Cancer Screening Program for Key Populations in Zhejiang Province from May 2020 to December 2021 were recruited, and their demographic information, lifestyle and disease history were collected through a questionnaire survey. Qualitative or quantitative FIT along with a questionnaire-based risk assessment were employed as the initial screening tests. Individuals who were positive in any FIT or had high-risk assessment results were required to attend a subsequent colonoscopy examination. The positive rate, detection rate of colorectal cancer, positive predictive value and number of colonoscopies required were compared between qualitative and quantitative FITs, and stratified analyses by gender and age were conducted.@*Results@#Totally 4 099 769 participants were included. The qualitative FIT group included 3 574 917 individuals, yielding a positive rate of 11.35%, a detection rate of 1.19%, a positive predictive value of 0.48% and 83.84 colonoscopies required to detect one cancer case. The quantitative FIT group involved 524 852 individuals, yielding a positive rate of 6.70%, a detection rate of 2.31%, a positive predictive value of 1.01% and 43.23 colonoscopies required to detect one cancer case. The quantitative FIT group showed significantly higher detection rate of colorectal cancer, higher positive predictive value and less number of colonoscopies required compared to the qualitative FIT group (all P<0.05). The same results were obtained after stratification by gender and age.@*Conclusion@#Compared to qualitative FIT, quantitative FIT improves the detection of colorectal cancer and reduces the workload of colonoscopy examinations, making it more suitable for colorectal cancer screening in large-scale populations.

A study on obese patients' participation in cancer screening programs: an example from Turkey

SUMMARY OBJECTIVE: Obesity is associated with many types of cancers. Despite this, the participation of obese individuals in cancer screenings is limited. The aim of this study was to evaluate the cancer screening-related attitudes of obese patients. METHODS: The study included 185 obese patients who presented to the obesity center (OC) and 191 obese patients who presented to the family medicine outpatient clinic from October to December 2019. The participants in both groups were first asked whether or not they had ever undergone any cancer screening tests and then provided with relevant training. After 3 months, the participants were contacted again and their attitudes toward cancer screening tests were re-evaluated. RESULTS: Patients who followed in the OC were found to have higher awareness of and compliance with cancer screening tests than the obese patients admitted to the outpatient clinic. The factors of being female, being followed in the OC, and residing in an urban area were positively associated with participation in cancer screening tests. CONCLUSION: Monitoring obese patients in target-oriented facilities such as an OC increases the chance of success in the fight against obesity and related health problems.

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.

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.

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.

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.

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.

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.

Factors Associated with Presence of Human Papillomavirus Infection among Women: Findings from New Cervical Cancer Screening in Kelantan, Malaysia

@#Introduction: Human papillomavirus (HPV) infection is known to cause cervical cancer worldwide. Recently, Malaysia introduced HPV DNA detection testing for cervical cancer screening program. However, knowledge regarding factors for HPV infection among women still limited. Thus, this study aimed to determine the prevalence and factors associated with HPV infection among women in Kelantan, a north-eastern state of Malaysia. Methods: This study used secondary data extracted from HPV DNA test registry book and HPV DNA laboratory request forms. Data on all Malaysian women aged 30 to 49 years old in 2019 reported in registry book were included. Simple random sampling was applied. All information from book and forms were collected using proforma and analysed using SPSS. The outcomes were categorised into HPV infection and non-HPV infection. The parameters related to factors associated with HPV infection were determined using multivariable logistic analysis. Results: The prevalence of HPV infection among women attending the new cervical screening was 8.4% (95% CI 6.4%, 10.3%). Those aged between 30 and 39 years old (AdjOR 2.09; 95% CI 1.16, 3.78, p=0.014), had 5 or more parities (AdjOR 2.82; 95% CI 1.58, 5.06, p<0.001) and hormonal contraception users (AdjOR 7.48; 95% CI 4.07, 13.76, p<0.001) were significantly associated with HPV infection. Conclusion: Overall, the prevalence of HPV infection from this study is comparable to the local and international studies. Age, number of parities and hormonal contraception users influence the HPV infection. This finding could help in designing more targeted screening for cervical cancer.

This review endeavors to furnish a holistic insight into pancreatic cancer, encompassing its epidemiology, genomic characterization, risk factors, diagnosis, therapeutic strategies, and treatment resistance mechanisms. We delve into identifying risk factors, including genetic predisposition and environmental exposures, and explore recent research advancements in precursor lesions and molecular subtypes of pancreatic cancer. Additionally, we highlight the development and application of multi-omics approaches in pancreatic cancer research and discuss the latest combinations of pancreatic cancer biomarkers and their efficacy. We also dissect the primary mechanisms underlying treatment resistance in this malignancy, illustrating the latest therapeutic options and advancements in the field. Conclusively, we accentuate the urgent demand for more extensive research to enhance the prognosis for pancreatic cancer patients.

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.
