Batarfi, Nahid. "Saudi women's experiences, barriers, and facilitators when accessing breast and cervical cancer screening services." Thesis, University of York, 2012. http://etheses.whiterose.ac.uk/7558/.
Full textAbstract:
Background: Breast cancer is considered the most common cancer among females followed by cancers of the cervix, lung, and stomach. Its mortality can be avoided by early detection. Aim: This thesis aimed to explore Saudi women’s barriers facilitators and experiences, when accessing breast and cervical cancer screening services in the United Kingdom (UK) and Saudi Arabia. Methods: A mixed method approach was used to fulfil the thesis objectives. A quantitative questionnaire was administered to 503 Saudi women living in the United Kingdom and in Kingdom of Saudi Arabia. This was followed up by a qualitative study using seven focus groups discussions. Results: Survey and focus groups provided some consistent findings regarding Saudi women’s perceptions, knowledge, beliefs of the barriers and facilitators in accessing both breast and cervical cancer screening services in the UK and Saudi Arabia. Fear of having cancer and lack of knowledge of the importance of early detection, particularly in cervical cancer were major findings with regard to barriers to attend screening services. However, being employed and highly educated was correlated with better knowledge and awareness of the signs, symptoms, and treatment of both breast and cervical cancer. Participants shared their responsibilities with health professionals and the structure of the health system in the arrangement of early screening of breast and cervical cancers. Additionally, they suggested the role of media, education, and use of places such as mosques in disseminating information about the importance of early cancer detection. Conclusion: While the data reported in this thesis are encouraging, rich and diverse, conclusions must be drawn with caution. Important barriers included health and cultural beliefs and attitudes, language and unsupportive attitudes of health professionals. A majority of Saudi participants believed educational programs would increase breast and cervical cancer awareness and knowledge and use of screening services. The health belief model was utilized to structure and explain the thesis findings and analysis.

Full textAbstract:
Background: Introduction of nationwide breast and cervical screening programmes in Poland (2006) created an unprecedented opportunity to explore the predictors of breast and cervical cancer prophylactic behaviours in a society unexposed to population screening. The study aims to add to the body of knowledge on predictors that could be common for other countries in a similar geo-political situation, aiming to introduce nationwide breast and cervical screening programmes. Methods: A data subset (N=4,290) from a large representative survey (N=7,948) on cancer knowledge and prophylaxis, conducted by the Cancer Oncology Institute in Warsaw close to the introduction of nationwide breast and cervical cancer screening, was used in this thesis. Behaviours and knowledge were described and logistic regression used to identify predictors of mammography and cytology uptake. Results: Women’s level of cancer knowledge was evenly distributed (49.2% low and 50.8% high scores). However, knowledge on cervical cancer was lower than for breast. Higher knowledge was linked to higher education, better material conditions, cancer diagnosis, or practicing any type of the studied prophylaxis and lower levels of knowledge was associated with being aged 18-24 or ≥70 y.o., being widowed, and living in village. Even though 93% (N=3,970) of respondents were aware of the need for breast self-examination (BSE), only 32.3% regularly practiced BSE. Majority (92.3%, N=3,943) knew that mammography can allow early cancer detection but only 52.5% ≥ 50 y.o. (32.1% all ages) declared ever having it. Similarly, 90.7% (N=3,871) knew that cytology allows early detection of cancer and 78.8% have ever undertaken it cytology but only 53.6% had it done every 1-3 years. Up to 4% indicated test unavailability of either test as the reason for non-attendance. The most common barriers included: feeling of no need for such test (37.9-44.9%) and lack of referral (28.7%-39.2%). Women with the highest education levels, the 3 ones living in cities above 100,000 inhabitants, or with highest cancer knowledge were the most likely to ever get screened for breast and cervical cancers. Additionally BSE was found to predict mammography whilst cytology was also predicted by: household size, marital status, having a family member or a friend with cancer. Conclusions: Low screening uptake could be reflective of the fact that there was no nationally available screening but only a small proportion reported non-attendance due to unavailability of tests. This suggests that the uptake was driven by other factors (e.g., cancer knowledge, education) than population screening availability. Particular attention should be paid to the provision of cancer related knowledge. A follow up study is recommended to assess whether women’s knowledge and screening behaviours improved since the conduct of this survey.

Full textAbstract:
Breast and cervical cancer disparities among Hispanic and American Indian women are a significant public health problem. Breast cancer is the most common neoplasm among Hispanic women. Cervical cancer has a higher incidence and mortality among Hispanic women compared to non-Hispanic White women. Breast cancer detection often comes late for American Indian women and breast cancer survival for this population is relatively poor. Hispanic and American Indian women who reside in rural areas of Arizona are especially at-risk of non-participation in breast and cervical cancer screening programs. This dissertation utilized data from two sources: a health-education intervention trial designed to increase mammography screening among women living in a rural area along the U.S.-Mexico border of Arizona and survey data from multiple years of the Arizona Behavioral Risk Factor Survey (BRFS) focusing on breast and cervical cancer screening self-reported behaviors. The purpose of the dissertation research was to identify factors associated with cancer screening behaviors among Hispanic and American Indian women that reside in rural Arizona settings. Hispanic women who participated in the promotora-based educational intervention program were more likely to report receiving a mammogram at the followup compared to women who did not participate in the program. Results from both the baseline community survey and the BRFS showed that Hispanic women who received prior recommendations from a clinician to get both mammography and Pap smear were more likely to report they received a mammogram within the past year and a Pap smear within the past three years. Rural Hispanic and American Indian women reported lower rates of ever having had breast and cervical cancer screening compared to their urban counterparts. Breast and cervical cancer screening use in these populations can potentially be increased with at least two strategies. First, clinician recommendation of both mammograms and Pap smears and opportunistic screening during regular clinic visits may increase breast and cervical cancer screening coverage. Secondly, culturallyappropriate interventions that utilize promotoras or lay health advisors could increase screening rates. In conclusion, Hispanic and American Indian women that reside in rural areas of Arizona, whether throughout the State or along the U.S.-Mexico border, are two underserved populations in Arizona with low rates of breast and cervical cancer screening that need to be addressed in order to reduce the burden of cancer in these populations.

Full textAbstract:
Screening for breast and cervical cancers can reduce morbidity and mortality through early detection, yet many women are not getting regular lifesaving screenings as recommended. 2 The National Breast and Cervical Detection Program (NBCCEDP) was established in 1990 in order to provide low-income, uninsured, and underserved women access to breast and cervical cancer screening and diagnostic services. Georgia’s participation in the NBCCEDP led to the development of The Breast and Cervical Cancer Program (BCCP), which provides cancer screening to women 40 to 64 years of age who are uninsured and/or underinsured and at or below 200% poverty level.
Deaths from breast and cervical cancers could be avoided if screening rates increased among women at risk. In order to better eliminate barriers to screening, Georgia’s Breast and Cervical Cancer Program uses client navigators to communicate with minority populations. The purpose of my thesis study was to assess the effectiveness of the Client Navigator Program utilized to enhance breast and cervical cancer screening rates for women throughout Georgia. Evaluation findings demonstrated that personal characteristics of Client Navigators, internal characteristics of the program itself, resources provided by the program, and program partnerships were the areas of greatest program strength. Funding was repeatedly listed as the greatest program threat. Findings from this study provide insights for how the overall program can be improved in the future, and thus, improving health outcomes for women who are at greatest risk of breast and cervical cancer throughout the state.

Full textAbstract:
A qualitative feminist study, informed by social constructionist epistemology, antiracist theories and intersectionality perspectives, was conducted in order to understand South Asian immigrant women’s access to and experiences with breast and cervical cancer screening services in Canada. Particular attention was paid to the wider context of their lives and their experiences of migration, resettlement, integration and general access to the Canadian healthcare system. The study also explored how the broader systems, structures and policies in Canadian society shape South Asian immigrant women’s participation in and access to cancer screening services. Thirty one South Asian immigrant women were interviewed in individual, couple and group settings in greater Vancouver. Research findings indicated that women’s age, length of stay since immigration, educational and generational status, not/having a family history or symptoms impact their use or lack of use of cancer screening services; but these factors also intersect in complex ways with various systemic and structural issues including not having a recommendation from physicians, women’s financial instability, access to income, employment, settlement services and community resources, levels of socioeconomic integration and familiarity with the Canadian healthcare system, and gender roles and responsibilities. Women’s narratives also showed that the immigration factor amplify the intersecting forms of inequities and the social determinants of health such as gender, class, poverty, racialization and discrimination, and affect women’s physical and mental health and access to healthcare services, cancer screening being one of them. An intersectional analysis revealed that the gendered and racialized immigration and integration policies, multicultural discourses and neoliberal ideologies and practices intersect to situate South Asian immigrant women into racialized and disadvantaged situations as the ‘other’ wherein access to preventive cancer screening services becomes especially challenging. South Asian women’s access to cancer screening and other healthcare services needs to be understood beyond the attempts to know their cultural health beliefs and practices, and beyond the neoliberal ideas of ‘self-care,’ ‘individual responsibility,’ ‘patient empowerment,’ and ‘culturally sensitive care.’ Also, equitable access to health care cannot be ensured without resisting these women’s racialized position as the ‘other’ and addressing the social, political, historical, material and structural inequities in Canadian society.

Full textAbstract:
Vietnamese women experience cancer screening disparities and inconsistent adherence to screening guidelines. The goal of this study was to implement and evaluate a breast and cervical cancer screening intervention to promote cancer screening knowledge, attitudes, self-efficacy, intention, and behavior for Vietnamese women. Secondary objectives of the study included examining the relationships between cultural variables (e.g., acculturation, ethnic identity, religiosity, and collectivism) and cancer screening variables. The study enrolled 102 women from the greater Richmond metropolitan area. Participants were assigned to an intervention group or a print material control group. In the intervention session, participants were exposed to information on female cancers and were taught how and where to access Pap tests and clinical breast exams (CBE). Follow-up data were collected six months after the intervention to determine whether or not there were longer-term program effects. Intervention participants also took part in focus groups that examined their reactions, thoughts, feelings, and experiences in regards to the intervention. In addition, focus groups explored participants’ sources of motivation for cancer screening and whether they shared information obtained in the sessions with other individuals. The intervention was effective in promoting immediate and longer-term gains in breast and cervical cancer knowledge, attitudes towards screening, self-efficacy for screening, and actual screening behaviors. The study’s findings indicated that acculturation was linked to higher levels of self-efficacy and screening behavior and less positive attitudes towards screening. Personal and social extrinsic religiosity were associated with more positive attitudes towards screening. Social extrinsic religiosity was also associated with more self-efficacy for screening and screening behavior. Intrinsic religiosity was linked to lower levels of self-efficacy for screening. Focus group discussions revealed that the women shared cancer-related information with friends, female family members, and husbands. Focus group discussions also revealed that emphasis on caretaking roles may help increase women’s adherence to screening guidelines. This study provides evidence for the effectiveness of culturally-tailored strategies in developing cancer screening interventions for the Vietnamese population. This study also demonstrates how health information is transmitted across informal channels within faith-based communities.

Deakin University. School of Psychology, 2001. http://tux.lib.deakin.edu.au./adt-VDU/public/adt-VDU20040825.105605.
Full textAbstract:
The first aim of the research was to determine the applicability of certain variables from the Health Belief Model (HBM), the Theory of Reasoned Action (TRA), the risk dimensions from the Psychometric Paradigm, the Common-Sense Model of Illness Representations and the Locus of Control to Italian womens beliefs and behaviours in relation to screening mammography. These models have predominantly been derived and evaluated with English-speaking persons. The study used quantitative and qualitative methods to enable explanation of research-driven and participant-driven issues.
The second aim was to include Italian women in health behaviour research and to contrast the Italian sample with the Anglo-Australian sample to determine if differences exist in relation to their beliefs. In Australia many studies in health behaviour research do not include women whose first language is not English.
The third aim was to evaluate the Anti-Cancer Council of Victorias (ACCV) Community Language Program (CLP) by: (a) identifying the strengths and weaknesses of the program as seen by the participants; and (b) assessing the impact of the program on womens knowledge and beliefs about breast cancer, early detection of breast cancer, self-reported and intended breast screening behaviours. The CLP is an information service that uses womens first language to convey information to women whose first language is not English. The CLP was designed to increase knowledge about breast and cervical cancer.
The research used a pre-test-intervention-post-test design with 174 Italian-born and 138 Anglo-Australian women aged 40 years and over. Interviews for the Italian sample were conducted in Italian. The intervention was an information session that related to breast health and screening mammography. Demographic variables were collected in the Pre-Test only. Qualitative open-ended questions that related specifically to the information session were collected in the Post-Test phase of the study. Direct logistic regression was used with the participants beliefs and behaviours to identify the relevant variables for language (Italian speaking and English-speaking), attendance to an information session, mammography screening and breast self-examination (BSE) behaviour. Pre- and Post-Test comparisons were conducted using chi-square tests for the non-parametric data and paired sample t-tests for the parametric data.
Differences were found between the Italian and Anglo-Australian women in relation to their beliefs about breast cancer screening. The Italian women were: (1) more likely to state that medical experts understood the causes of breast cancer; (2) more likely to feel that they had less control over their personal risk of getting breast cancer; (3) more likely to be upset and frightened by thinking about breast cancer; (4) less likely to perceive breast cancer as serious; (4) more likely to only do what their doctor told them to do; and (5) less likely to agree that there were times when a person has cancer and they dont know it.
A pattern emerged for the Italian and Anglo-Australian women from the logistic regression analyses. The Italian women were much more likely to comply with medical authority and advice. The Anglo-Australian women were more likely to feel that they had some control over their health. Specifically, the risk variable dread was more applicable to the Italian womens behaviour and internal locus of control variable was more relevant to the Anglo-Australian women. The qualitative responses also differed for the two samples. The Italian womens comments were more general, less specific, and more limited than that of the Anglo-Australian women. The Italian women talked about learning how to do BSE whereas the Anglo-Australian women said that attending the session had reminded them to do BSE more regularly.
The key findings and contributions of the present research were numerous. The focus on one cultural group ensured comprehensive analyses, as did the inclusion of an adequate sample size to enable the use of multivariate statistics. Separating the Italian and Anglo-Australian samples in the analyses provided theoretical implications that would have been overlooked if the two groups were combined. The use of both qualitative and quantitative data capitalised on the strengths of both techniques. The inclusion of an Anglo-Australian group highlighted key theoretical findings, differences between the two groups and unique contributions made by both samples during the collection of the qualitative data. The use of a pre-test-intervention-post-test design emphasised the reticence of the Italian sample to participate and talk about breast cancer and confirmed and validated the consistency of the responses across the two interviews for both samples. The inclusion of non-cued responses allowed the researcher to identify the key salient issues relevant to the two groups. The limitations of the present research were the lack of many women who were not screening and reliance on self-report responses, although few differences were observed between the Pre- and Post-Test comparisons.
The theoretical contribution of the HBM and the TRA variables was minimal in relation to screening mammography or attendance at the CLP. The applicability of these health behaviour theories may be less relevant for women today as they clearly knew the benefits of and the seriousness of breast cancer screening. The present research identified the applicability of the risk variables to the Italian women and the relevance of the locus of control variables to the Anglo-Australian women. Thus, clear cultural differences occurred between the two groups.
The inclusion of the illness representations was advantageous as the responses highlighted ideas and personal theories salient to the women not identified by the HBM. The use of the illness representations and the qualitative responses further confirmed the relevance of the risk variables to the Italian women and the locus of control variables to the Anglo-Australian women.
Attendance at the CLP did not influence the women to attend for mammography screening. Behavioural changes did not occur between the Pre- and Post-Test interviews. Small incremental changes as defined by the TTM and the stages of change may have occurred. Key practical implications for the CLP were identified. Improving the recruitment methods to gain a higher proportion of women who do not screen is imperative for the CLP promoters. The majority of the Italian and Anglo-Australian women who attended the information sessions were women who screen. The fact that Italian women do not like talking or thinking about cancer presents a challenge to promoters of the CLP. The key theoretical finding that Italian women dread breast cancer but comply with their doctor provides clear strategies to improve attendance at mammography screening. In addition, the inclusion of lay health advisors may be one way of increasing attendance to the CLP by including Italian women already attending screening and likely to have attended a CLP session.
The present research identified the key finding that improving Anglo-Australian attendance at an information session is related to debunking the myth surrounding familial risk of breast cancer and encouraging the Anglo-Australian women to take more control of their health. Improving attendance for Italian women is related to reducing the fear and dread of breast cancer and building on the compliance pattern with medical authority. Therefore, providing an information session in the target language is insufficient to attract non-screeners to the session and then to screen for breast cancer.
Suggestions for future research in relation to screening mammography were to include variables from more than one theory or model, namely the risk, locus of control and illness representations. The inclusion of non-cued responses to identify salient beliefs is advantageous. In addition, it is imperative to describe the profile of the cultural sample in detail, include detailed descriptions of the translation process and be aware of the tendency of Italian women to acquiesce with medical authority.

Full textAbstract:
This dissertation examines sociodemographic determinants and preventive health behaviors among women 40-64 years of age who participated in the Virginia Department of Health’s Every Woman’s Life breast cancer screening program. Utilizing secondary data, this research sought to explore patterns of breast cancer incidence, mammography screening utilization and sources of health information among low-income women.
The Virginia Department of Health provided a large sample size (N=34,942) on which to perform binary logistic regression analyses. Sociodemographic determinants and preventive health behaviors were analyzed as potential influencing factors in the diagnosis of breast cancer, the stage at the time of diagnosis and source of health information. Additionally, frequencies across all variables were explored and compared to state and national statistics, where appropriate.
In this study, cancer and preventive health disparities reported in the literature persist within this sample of low income women. The binary regression analyses demonstrated that there are marginally worse outcomes for each level of decreasing income. Those with the most “wealth” were less likely to be diagnosed with invasive breast cancer and were more likely to obtain health information from a health provider. Additionally, it was determined that those without a prior mammogram were more likely to be diagnosed with breast cancer and the cancer was more likely to be invasive.
The aims of the Every Woman’s Life program align with Affordable Care Act (2010) to strengthen health care and eliminate cancer disparities. Highlighting program characteristics and presenting these analyses allows policymakers, program officials and practitioners an opportunity to tailor health promotion activities while considering all tiers of influence.

This diploma thesis deals with the national screening programs for cancer diagnosis. The goal of this thesis is to find a proper way how to evaluate the effectivity of screening programs as well as their influence on the intensity of mortality from certain types of cancer. For the purpose of finding out necessary information were used data related to the diagnosis of colorectal cancer, a diagnosis of cervical cancer and breast cancer in the population of the Czech Republic between 1977 - 2011. This thesis is divided into eight chapters. The first chapter is an introduction to the topic and contains the description of the main goals. The second chapter defines terms that are crucial for this thesis. The third chapter is devoted to data sources and institutions that collect different types of data and health statistics. The next chapter deals with the epidemiology of all described types of cancer and also provide information on risk factors and symptoms of the disease. The fifth chapter looks back at trends in mortality and incidence of the most common malignant tumors in the Czech Republic. The sixth chapter describes planning and implementation of screening processes. The seventh history of screening programs in the Czech Republic. The eighth chapter deals with the rules and regulations of the EU Council and the World Health Organization. The ninth chapter represents the final assessment of Czech screening programs, compared both to the WHO guidelines and the results in the world. The last chapter is including description of mortality and their reaction on screening programs. Text describes even comparison with two other European countries (Germany, France).

Full textAbstract:
Due to the constantly increasing epidemiological burden of our population on oncological diseases, nationwide preventive programs for selected types of malignant tumors have been introduced within the Czech health system. The aim of this thesis is to analyze and evaluate these screenings, such as mammographic screening, cervical screening and screening of the colon and rectum. The subject of the analysis is the mortality rates for breast cancer (C50), cervix (C53) and colon and rectum cancer (C18-21) between 1994 and 2015. The main focus is on question of whether the development of the mortality rate for selected neoplasms depends on the degree of coverage rate by a preventive program.

Full textAbstract:
Objectives
This dissertation had two overarching objectives:
1. To determine how stakeholders perceive women’s preferences for cervical
screening modalities.
2. To understand methods to measure women’s cervical screening preferences, to
inform the development and testing of a person-centered, evidence-informed approach to
preference-elicitation.
Methods
The overarching conceptual framework was the Ottawa Decision Support Framework.
The first objective was addressed by interview studies with (1) guideline developers and program
managers and (2) health professionals and women considering screening. This was
complemented by a systematic review of quantitative, qualitative and mixed-methods studies of
women’s cervical screening preferences, using the Grading of Recommendations, Assessment,
Development, and Evaluation approach to developing preference-based recommendations. This
approach was also used in a systematic review of methods to elicit women’s preferences,
addressing the second objective. These findings led to the development and field testing of a
preference-elicitation tool using International Patient Decision Aid Standards criteria, and the
development of a protocol for a population-based study of women’s preferences.
iv
Results
Objective 1
Experts disagree about whether there is enough evidence to include alternative modalities
in cervical screening programs. Women and health care professionals do not recognize that
women face a choice to participate in cervical screening. A narrative synthesis of relevant
literature presented challenges in aggregating preferences across diverse study objectives,
designs, and contexts.
Objective 2
Preference-elicitation approaches for cervical screening are heterogenous in design and
rigour. I therefore developed and field tested a tool to elicit women’s preferences, which
demonstrated that women found the tool helpful to identify their preferences. I then propose a study that uses multiple methods to apply the tool more broadly.
Conclusions
Synthesized preferences data might not be the optimal approach to incorporate preferences into cervical screening guidelines. A tool grounded in shared decision-making can help women identify their informed, values-based screening preferences.

Ces travaux de thèse sont motivés par le développement de techniques d’imagerie alternatives pour le diagnostic précoce du cancer du sein. Parmi celles-ci, l’imagerie photoacoustique couple potentiellement les avantages de deux modalités d’imagerie non-invasives, à savoir la quantification de contrastes physiologiques du fait de l’excitation optique et la haute résolution du fait d’un sondage acoustique.Le but de ces travaux est de proposer une modélisation multiondes du phénomène photoacoustique, et d’incorporer ce modèle dans un algorithme de reconstruction efficace pour résoudre le problème inverse. Celui-ci se rapporte à la reconstruction de cartes de propriétés physiques (optique et/ou acoustiques) de l’intérieur du sein. La Méthode des Eléments Finis (MEF) a été retenue pour résoudre l’équation de propagation optique. Pour la résolution de l’équation de propagation acoustique, une méthode semi-analytique, basée sur des calculs par transformées de Fourier (méthod k-space), a été choisie. Pour la résolution du problème inverse, deux approches ont été étudiées : i) un sondage passif, permettant de remonter à la distribution de pression initiale, à l’aide de la méthode de retournement temporel ; ii) un sondage actif, où l’on interroge le milieu sélectivement sous différentes excitations, permettant de remonter quantitativement aux propriétés optiques du milieu. On appelle cette dernière approche Tomographie PhotoAcoustique Quantitative (TPAQ). Une étude spécifique sur le protocole d’illumination/détection a été conduite, prenant également en compte les contraintes expérimentalesThe present work was motivated by the development of alternative imaging techniques for breast cancer early diagnosis, that is photoacoustic imaging, which potentially couples the merits of optical imaging and ultrasound imaging, that is high optical functional contrasts brought by optical probing and high spatial resolution by ultrasound detection. Our work aims at modeling the photoacoustic multiwave phenomenon and incorporate it in an efficient reconstruction algorithm to solve the inverse problem. The inverse problem consists in the recovery of interior maps of physical properties of the breast. The forward model couples optical and acoustic propagations. The Finite Element Method (FEM) was chosen for solving the optical propagation equation, while a semi-analytical method based on Fourier transforms calculations (k-space method) was preferred for solving the acoustic propagation equation. For the inverse model, time reversal method was adopted to reconstruct the initial pressure distribution, an active approach of the inverse problem was also achieved, which decoupled the optical properties from measured photoacoustic pressure, this approach is called quantitative photoacoustic tomography (QPAT), in this approach, illumination/detection protocol was studied, and the experimental set up is also take into consideration. In the last step, photoacoustic pressure measurements obtained from experiment and simulation are studied and compared

Full textAbstract:
Les cancers du sein peuvent être classifiés selon le statut de récepteur d’estrogène (RE), de récepteur de progestérone (RP), de récepteur HER2, ou selon quatre sous-types (Luminal A, Luminal B, HER2-enrichi, Triple-négatif) ayant des propriétés biologiques et cliniques différentes. La sensibilité du dépistage par mammographie pourrait varier selon ces types de cancers mais ceci n’est pas encore clair. L’agressivité de la tumeur, mesurée par le grade histologique pourrait expliquer cette association. Les types de cancers d’intervalle ont été comparés à ceux de cancers détectés par dépistage parmi 1536 cas infiltrants provenant d’un centre de référence de Québec. Les tumeurs RE-négatif, RP-négatif, HER2-positif, Luminal B, HER2-enrichi et TPN étaient tous plus fréquentes chez les femmes avec cancers d’intervalle que chez celles avec cancers détectés par dépistage. À l’exception des tumeurs HER2-positif et HER2-enrichi, le grade histologique expliquait en grande partie la variabilité observée entre les types de cancer et la sensibilité.Breast cancers can be classified according to tumour estrogen (ER) and progesterone (PR) receptors, human epidermal growth factor receptor 2 (HER2), and according to four subtypes (Luminal A, Luminal B, HER2-enriched, Triple-negative), each with different biological and clinical profiles. These tumour types may also influence screening mammography sensitivity but this is still not clear. Tumour aggressiveness, measured by the histological grade, may also play a role in explaining this association. Interval cancer types were compared to screen-detected cancer types in 1536 invasive cases obtained from a reference center in Quebec. ER-negative, PR-negative and HER2-positive, Luminal B, HER2-enriched and TPN tumours were all more frequent in women with interval cancers than in women with screen-detected cancers. Except for HER2-positive and HER2-enriched tumours, histological grade explained most of the variability observed between tumour receptor status, subtypes and sensitivity.

Full textAbstract:
This thesis examines issues related to cervical cancer epidemiology and prevention through screening, with the aim of informing policy regarding setting up an organised cervical screening programme in Hong Kong. There are five studies described here. The first, a case control study, indicated that screening is effective in preventing invasive cervical cancer among Chinese women. In addition, the main risk factors identified in other studies, were confirmed as risk factors in this population. Secondly, a cross-sectional study examined the pattern of cervical screening in Hong Kong. The screening system at that time achieved poor coverage, was inefficient, inequitable and potentially harmful. Thirdly, a cross-sectional study of practitioners showed the diversity in provision of services and the lack of consensus among practitioners in the management of abnormal smears. Fourthly, the use of an industrial quality management technique in monitoring quality, using inadequate smear rates as an indicator is assessed. It demonstrated that this is an efficient and useful method that can be applied to monitoring a screening programme. The last study was a randomised controlled trial showing that when women are given balanced information on cervical screening, with information on both the harms and benefits, relatively fewer chose to attend. The implications of these studies in relation to setting up a screening programme are discussed.

The aim of this thesis is to carry out an in-depth study of various aspects of breast cancer epidemiology. Firstly, we have confirmed that DCIS incidence in Girona has increased over recent decades. Proportions of screen-detected cancers, interval cancers and non-screen-detected cancers during the start-up phase of the mammographic screening programme were found to be 42.2%, 5.8% and 52.2%, respectively. Secondly, we have found that luminal A-like was the most frequent subtype associated with the best survival rate, while triple-negative breast cancer was related to the lowest survival rate. Importantly, we have concluded that breast cancer molecular subtype defined by IHC biomarkers provides prognostic value, regardless of age, tumour size, histological grade, lymph node involvement and method of detection. Finally, we have demonstrated that method of detection also provides prognostic value regardless of age, tumour size, histological grade, lymph node involvement and breast cancer molecular subtype defined by IHC biomarkers.L’objectiu d’aquesta tesi és realitzar aprofundir en diversos aspectes de l'epidemiologia del càncer de mama.

Per altra banda, el subtipus amb la supervivència més elevada i més baixa van ser el luminal A-like i el triple negatiu, respectivament. És important destacar que el subtipus molecular de càncer de mama definit per biomarcadors determinats amb tècniques d’IHC proporciona valor pronòstic, independentment de l'edat, la mida, el grau histològic, l’afectació dels ganglis i el mètode de detecció.

Full textAbstract:
Despite multiple campaigns by the American Cancer Society, reports indicate that Latinas living in the United States who contract breast cancer are more likely than Anglos to die. These findings correlate with low participation in breast cancer screenings among Latinas. The objective of this study was to identify key obstacles that influence Latinas' low participation in breast cancer screenings, based on their health beliefs, knowledge of screenings, acculturation, and socio-economic factors.The study was a face-to-face informal interview, combined with a survey questionnaire conducted at churches, social clubs and/or at the participants' homes in a southwest Florida urban community. The sample consisted of a total of 50 women: all of the participants were Latinas 40 years of age and over; they had to be fluent in Spanish or English or both. A Spanish-English bilingual individual conducted a personal interview in the preferred language of each participant.
The first part of the interview was to identify barriers that affect screenings. The second part used a survey to weigh the identified factors in order to determine their importance to the participants' health decisions. This study used a health belief model scale to evaluate women's beliefs about breast cancer, and the benefits of screenings.The research results revealed that Latinas who participated in this study were acculturated to the United States culture; the largest group of participants reported being from Colombia, followed by Cuba and Puerto Rico; only two of the participants were Mexican. Seventy-eight percent of the participants self- reported having yearly mammograms, and 74% performed monthly breast self examination BSE; 60% were bilingual; 68% had some kind of health insurance. These results differ from earlier studies from the western United States where the majority of Latinas were of Mexican or Central American origin.
This suggested that Latinas from Southwest Florida are different from Latinas in other areas of the United States. A weak but significant correlation was found between acculturation and perceived barriers to breast cancer screenings, (r = 0.45, p = .01); Latinas who are more acculturated perceived more barriers than those who are less acculturated. There was not significant difference between participants who had health insurance and those who did not (t = 0.96, p = .35). The results of this study are significant for nurses and especially for advanced practice nurses, who can assess patients' knowledge about cancer in general, and breast cancer in particular when caring for Latinas; of particular concern should be the evaluation of patients' levels of acculturation, health beliefs, and understanding of the English language. Still the fundamental barrier to Latinas not bilingual in Spanish and English may be the lack of resources and information in Spanish.

Cervical cancer is the ninth leading cause of female cancer deaths in Hong Kong. In 2011, 391 new cases of cervical cancer were diagnosed and the age-standardized incidence rate was 7.2 per 100,000 standard populations. In 2012, 133 women died from this cancer, accounting for 2.5% of female cancer deaths. The age-standardized death rate of cervical cancer was 2.1 per 100,000 standard populations.
Human papillomavirus (HPV) infection is an established cause of cervical cancer. HPV vaccines offer more than 70% protection for women against HPV types 16 and 18 infections and their related cervical precancerous lesions and cervical cancer. As there are usually no symptoms in high-risk HPV infection, it is often diagnosed at a late stage. Regular cervical smears can offer early detection of pathological changes and pre-cancerous stage for a timely medical treatment to prevent progression to cervical cancer.
The Cervical Screening Programme (CSP) of Department of Health (DH) was launched on 8 March 2004. It is a voluntary program with the objectives to increase the population coverage of cervical screening among women and to reduce the incidence and mortality of cervical cancer in Hong Kong. Women participating in the programme are encouraged to have cervical smears in the medical centres of their own choices and to provide their cervical smear information through their health care providers to the central registry of the CSP - The Cervical Screening Information System (CSIS). As at 31 December 2013, 491,674 women have registered with CSP.
When DH implemented CSP in March 2004, a report was published in the same year showing evidence that an organized screening compared with the opportunistic screening could substantially increase benefits and reduce costs. Another local study conducted early this year supported by the Health Services Research Fund also highlighted the importance and urgency in enhancing the current screening protocol. It is of public health interests to study and compare the programme outcomes with countries like Finland, Australia, UK and Japan where different policy was adopted for the prevention of cervical cancer. Information gathered from research papers on epidemiological studies has been collected and analyzed on population benefit (outcome, access, disparities), cost (cost benefit, efficiency, cost containment), equity, feasibility and constituency perspectives in formulation of the policy alternatives.
In conclusion, strengthening what is already in place with better allocative efficiency could protect the female population against cervical cancer. From the education perspective, emphasis on the risk of HPV infection in the sex education curriculum would raise the awareness on the precaution of HPV infections amongst young females. Additionally, vaccination at the age of 12 can provide protection against most types of HPV. It is strongly recommended that a cervical screening and HPV co-testing strategy at a triennial interval could provide the best cost and benefit effectiveness. Together they can enhance protection coverage of women at 12 through immunization and from 25 - 64 through active population screening. The ultimate objectives to reduce incidence, mortality and increase coverage could be achieved.published_or_final_version

Full textAbstract:
In cervical screening programmes, Papanicolaou test (Pap test) is the key screening tool. However Pap test is difficult to implement in low-resource region. Introduction of an economic, cost-effective and less skill demanding equipment is hence a potential direction of advance in cervical screening methodology.
Cervical carcinogenesis involves genetic instability which leads to chromosomal aneuploidy. Evaluation of aneuploidy may hence provide information for identifying cancer and precursor cells. An automated DNA-image-cytometry system (DNA-imager) capable of quantitating the DNA content of cells has recently been developed.
To evaluate the efficacy of DNA-imager in cervical cancer screening, a total of 483 residual ThinPrep liquid-based cytology (LBC) samples after diagnosis were retrieved and evaluated by the DNA-imager. The high risk human papillomavirus (HPV) status of the atypical squamous cells of undetermined significance (ASC-US) samples has been tested as a parallel study. According to established criteria, 423 out of the 483 samples were satisfactory for downstream analysis. The samples were designated “Normal”, “Suspicious” or “Abnormal” according to their DNA aneuploidy and proliferation activity.
Significantly more high grade lesion samples (HSIL and SCC) were designated as “Abnormal” by DNA-imager than were lower grade lesion samples (Negative, ASC-US, AGC, ASC-H, and LSIL) (94.19% vs 51.04%, p<0.0001). For detecting ≥HSIL, DNA-imager achieved high sensitivity and specificity (94.19% and 48.96%) using “Abnormal” as cut off. Adopting a more stringent definition of “Suspicious” or “Abnormal” would increase the sensitivity to 100% but decreased the specificity to 24.33%.
Regarding ASC-US triage, DNA-imager achieved a sensitivity and specificity of 80.00% and 71.29% respectively when “Abnormal” was used as test positive to predict cases with ≥HSIL follow-up in the next two year. The sensitivity increased but the specificity decreased to 90.00% and 34.65% respectively if “Suspicious or above” was used as indicator of undesirable follow-up. HR-HPV test, on the other hand, was able to identify all cases with ≥HSIL upon follow-up (sensitivity = 100%) but the specificity was only 15.84%. Among these ASC-US sample, test positivity of the two tests showed poor concordance with each other (Cohen’s κ = 0.062 and 0.074 respectively for “Suspicious or above” or “Abnormal”, respectively).
Our findings suggested that DNA-imager may be a useful tool for automated primary screening of cervical cancer

Full textAbstract:
Cervical cancer is a disease that annually claims the lives of over a quarter of a million women. A substantial number of these deaths could be prevented if population wide cancer screening, based on the Papanicolaou test, were globally available. The Papanicolaou test involves a visual review of cellular material obtained from the uterine cervix. While being relatively inexpensive from a material standpoint, the test requires highly trained cytology specialists to conduct the analysis. There is a great shortage of such specialists in developing countries, causing these to be grossly overrepresented in the mortality statistics. For the last 60 years, numerous attempts at constructing an automated system, able to perform the screening, have been made. Unfortunately, a cost-effective, automated system has yet to be produced. In this thesis, a set of methods, aimed to be used in the development of an automated screening system, are presented. These have been produced as part of an international cooperative effort to create a low-cost cervical cancer screening system. The contributions are linked to a number of key problems associated with the screening: Deciding which areas of a specimen that warrant analysis, delineating cervical cell nuclei, rejecting artefacts to make sure that only cells of diagnostic value are included when drawing conclusions regarding the final diagnosis of the specimen. Also, to facilitate efficient method development, two methods for creating synthetic images that mimic images acquired from specimen are described.

Minority immigrant women are more likely to be diagnosed with and suffer from cervical cancer compared to other minority women in the United States. The purpose of this qualitative ethnographic study was to explore cultural health perceptions, behaviors, and barriers to cervical cancer prevention among Korean immigrant women (KIW) in Hawaii. The health belief model and the social-ecological model were used to guide the study. Data were collected using individual structured interviews with 20 KIW ages 21 to 65 who are first-generation KIW immigrant to Hawaii. Data were coded and analyzed to identify themes. Findings revealed that participants (a) prefer a female gynecologist and Korean-speaking physicians; (b) are highly motivated to maintain physical health, including prevention; (c) prefer culturally appropriate community-based cancer prevention programs, and (d) expect innovative health maintenance approaches. Findings may be used by healthcare providers to identify culturally specific health needs of KIW related to cervical cancer screening and to implement appropriate preventive measures for KIW to reduce cancer death.

Cervical cancer is the second leading cause of cancer deaths among women of all age groups in Zimbabwe, and mortality and incidence continue to increase. The purpose of this quantitative cross-sectional study was to assess the factors that influence the utilization of cervical cancer screening services by Zimbabwean women living in Harare, Zimbabwe. Because personal beliefs influence screening, this study was guided by the health belief model (HBM). A total of 394 women whose ages ranged from 18 to 65 years were recruited from a health care facility in Harare. A 40-item closed-ended questionnaire was used to assess participants' knowledge, attitudes, beliefs, and cervical screening practices. Descriptive analysis was used to characterize the sample, and logistic regression was used to explore the effects of the hypothesized predictor variables. Results indicated that the strongest predictors of screening were monthly income, marital status, and the HBM construct perceived barriers. The study may promote positive social change as findings may be used to formulate policies that may encourage women to adopt preventive screening practices, which may save lives and reduce costs associated with treating cervical cancer when diagnosed at an advanced stage.

Hispanic women in Texas show higher cervical cancer incidence rates as compared to all women in the United States. The rate of cervical cancer in the United States has reduced mostly due to regular cervical cancer screening. However, high cervical cancer among Hispanics in Texas may reflect low cervical cancer screening. The purpose of this quantitative study was to examine the insurance status (independent variable) and cervical cancer screening (dependent variable) among low-income Hispanic women, living in Texas Health Service Regions (HSRs), after controlling for age, marital status, and personal health care provider. The theoretical framework used in this study was the health belief model. Nine hundred and fifteen Hispanic women living in Texas HSRs, ages 21-65 years and who participated in Texas BRFSS 2015-2017, were the sample for this study. Univariate analysis was performed to obtain frequencies and percentages of all covariates. A Chi-square was conducted to determine if there was an association between any of the independent and the dependent variable and binomial logistic regression was used to answer the hypotheses. The findings from this study revealed no relationship with cervical cancer screening and the level of education. However, insurance status and income were statistically significant on receiving a Pap test among low-income Hispanic women in Texas HSRs (p

Full textAbstract:
The purpose of this thesis is to explore the theory, practice and application of costing with specific reference to cancer. In part it reviews the theory and guidelines related to costing methods including the recent focus on the analytical techniques used with cost data. In addition it examines how these theories and guidelines are applied in practice, by reviewing the literature on costs and cancer. The empirical research in this thesis applies costing methods to three specific cancer sites; breast, cervix and lung. This analysis provides information on the total burden of these specified cancers in terms of cost to a typical health authority (Trent). It also explores the hypothesis highlighted in previous studies that the cost of cancer increases with the stage of the disease. The final area of contribution for the thesis is in the application of recently suggested analytical techniques for cost data to the breast, cervical and lung cancer data sets; it investigates a number of proposed techniques for the analysis of skewed cost data and methods for data with incomplete patient follow up.

Full textAbstract:
The management of women with mild and moderate dyskaryosis remains controversial. Any strategy must aim to be safe, efficient and cost effective. Two alternative strategies consist of immediate colposcopy for all women or a policy of cytological surveillance with colposcopy reserved for women with persistent dyskaryosis. Instead of a blanket policy for all women, selective approaches might be useful if accurate predictors of underlying high grade cervical intraepithelial neoplasia (CIN) were identified. Finally the effective treatment of women is important to prevent the development of invasive cancer. Large Loop Excision of the Transformation Zone or LLETZ is a relatively new treatment modality which has rapidly been established as the preferred treatment for women with CIN but it's efficacy has not been studied beyond a period of six months. The core of the thesis is description of a large prospective randomised study carried out in the University of Aberdeen. This was a four year project sponsored by the charity Birthright (now Well-being). Nine hundred and two women with a single smear showing mild or moderate dyskaryosis were recruited and allocated in a random fashion to either an immediate treatment group and one of three surveillance groups with periods of up to 24 months before treatment. Outcome measurements included the cytological and histological results. The cost effectiveness of two alternate management strategies for women with mild dyskaryosis is also described. The use of social factors and virological tests as secondary screening techniques is examined to determine if they might select women with high grade disease. Finally, the outcome of treatment of women including 400 women from the Birthright study using large loop excision of the transformation zone (LLETZ) is assessed.

Cervical cancer is a global health problem and the most common cancer in women living in sub-
Saharan Africa (SSA). Various barriers to cervical screening have been identified. These include
cytology based screening. Cervical screening by means of visual inspection with 3% to 5%
acetic acid (VIA) can be implemented in a wide range of settings as no laboratory processing is
required. This study was a pilot study to determine the knowledge of women, employed by one
institution in Tshwane, regarding cervical cancer, whether VIA screening would be acceptable,
what the results of such screening would be as well as the practical lessons that could be
learnt to improve the screening process. The research study was an exploratory, descriptive
and contextual survey. The sampling method was convenient (n=31). Data were gathered by
means of self-reports using structured interviews. The results of the screening were documented
on a clinical record. The study provides evidence that VIA screening was acceptable to women.
However the knowledge of women, despite having a higher level of education, was low. Although
one of the participants was VIA positive, none was VIA positive/invasive cancer. Lessons learnt
included that the number of women that could be screened in a given time should not be overestimated and that clinical breast examinations should be offered concurrently with cervical screening campaigns.

Full textAbstract:
Chinese women have significantly lower rates of Pap testing than Euro-Canadian women
despite efforts to promote testing. Evidence suggests that Chinese women's reluctance to
undergo Pap testing may be related to culture-linked discomfort with sexuality. The purpose of
this study was to explore the role of sexuality in the interaction between acculturation and Pap
testing. Euro-Canadian (n = 213) and Chinese (n = 260) female university students completed a
battery of questionnaires. Euro-Canadian women had significantly more accurate sexual
knowledge, higher levels of sexual functioning, a broader repertoire of sexual activities and
higher Pap testing rates. Chinese women were more likely to cite embarrassment as a barrier to
Pap testing. Heritage acculturation, but not Mainstream acculturation, predicted Chinese
women's Pap testing behaviour. Mainstream acculturation was associated with more accurate
sexual knowledge, greater sexual desire and satisfaction. The findings provide support for the
hypothesis that low Pap testing rates in Chinese women are related to cultural attitudes towards
sexuality and highlight the importance of taking into account sexuality in seeking to understand
cervical cancer screening among cultural groups.
