Cervical cancer is an emerging public health problem in developing countries. Globally, it is the 3rd most common malignancy in women after breast and colorectal cancers and 4th most frequent cancer in women, with an estimated 570,000 new cases and 311,000 deaths in 2018. Cervical cancer screening in the developed countries is credited with the reductions in cervical cancer morbidity and mortality during the last 50 years. However, nearly 90% of cervical cancer deaths occur in less developed countries. Ghana has a cervical cancer rate of 26.4%. Further, it is the highest cancer incidence faced among women 25 to 44 years and has a mortality rate of 17.4% in this age group. Knowledge, culture, attitude, and beliefs are known to limit women's participation in Pap test screening programs. Guided by the health belief model, the purpose of this quantitative study was to examine how knowledge, attitude, culture, and religious beliefs affected intent to seek Pap test screening among adolescent girls in Accra, Ghana. A total of 155 participants ages 16 to 20 years completed a 30-item questionnaire. Descriptive frequencies were calculated. Correlation and Chi-square tests were also performed to assess associations with intent to screen with Pap test. Most girls (92%) had never heard about Pap test screening. There were statistically significant correlations between cervical cancer knowledge (p=0.032) and attitude (p=0.001) with intent to participate in Pap test screening. However, culture (p=0.049) and religious beliefs (p=0.529) were not significantly associated with screening intent. The implications for social change include informing practice and research on how cervical cancer prevention programs can be tailored to girls living in countries where different cultural and religious values are practiced.

Thesis (MCur)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: Title: Awareness, knowledge and experiences of women regarding cervical cancer in rural Kwa- Zulu-Natal, South Africa. Background: Cervical cancer has been identified as the second most common cancer in women and contributes to the high mortality rate in women. Among all cancers in women, cervical cancer is rated the second most common cancer in women worldwide. In poorly resourced settings, access to services offering cervical screening is still a challenge and it is estimated that more than 50% of women in developing countries have never had a single screening test for cervical abnormalities. Purpose: The purpose of this study was to assess women’s awareness, attitudes and experiences regarding cervical smear testing and for cervical cancer in rural KwaZulu-Natal and to better understand factors influencing access to and utilization of cervical cancer screening services by rural women. Methods: The method employed was a descriptive study using a questionnaire to collect quantitative data. The sample consisted of 69 women aged 30 years and above, was taken from women who were enrolled in the on-going Microbicide Clinical Trial and attending follow-up clinic visits between July and August 2009. The primary outcome measure for the analyses was who has been screened for cervical cancer and this was assessed from the previous history reports of the women. The secondary outcome measure was to investigate knowledge and perceptions regarding cervical cancer and screening. Socio-demographic factors associated with having been screened were also explored. Results: Out of 69 women, only N=13 (18.8%) reported ever screening for cervical cancer. More than half of women who had never screened reported lack of information as a barrier to screening N=50 (71.4%). Older women aged 35-45, 45 and above were less likely to screen compared to women aged 30 to 34 years of age (OR: 0.06). Having an educational background seemed to increase the likelihood to screen, twice if a woman had primary education (OR 2.0) and almost three times (OR 2.67) if a woman had a secondary or a higher education. More than half of the respondents considered themselves at risk for cervical cancer N=42 (60.8%) and almost all showed a willingness to screen in the future N=64 (93%). Conclusion: Most of the women in this study had never been screened for cervical cancer in their lifetime as reflected by n=55 (82%) while only n=14 (18%) ever screened for cervical cancer. The results of this study cannot be generalised to the population due to the small sample size. However, there is need to facilitate comprehensive health education and the implementation of cervical screening programmes to target women in rural communities to contribute to the success of the cervical screening programme. The results of this study showed that 60% of respondents were informed by health care professionals on cervical cancer screening. Health care workers also should play a vital role in educating communities on cervical cancer and on the benefits for cervical cancer screening, through reaching all patients who utilise health care services with cervical cancer information and also communities through outreach programmes. / AFRIKAANSE OPSOMMING: Titel: Vrouens se bewustheid, houding en ervarings van smeertoetse en servikale karsinoom in die landelike gebiede van KwaZulu-Natal Agtergrond: Servikale kanker is geïdentifiseer as die tweede mees algemene karsinoom in vrouens en dra by tot die hoë sterftesyfer in vrouens. Van al die tipes karsinoom wat by vrouens voorkom, is servikale karsinoom die tweede mees algemene karsinoom onder vrouens wêreldwyd. Die beskikbaarheid van dienste wat servikale smeer toetsing bied, is nog steeds ’n uitdaging in arm gebiede en daar word geskat dat meer as 50 % van vrouens in ontwikkelende lande nog nooit ’n toets vir enige servikale abnormaliteite gehad het nie. Doel: Die doel van hierdie studie was om vrouens se bewustheid, houding en ervarings van servikale smeer toetsing en van servikale karsinoom in die plattelandse gebiede van KwaZulu-Natal te toets en om ’n beter begrip te kry van faktore wat ’n invloed het op toegang tot en gebruik van servikalesmeer toetsing by vrouens in landelike areas. Metode: Die metode wat gebruik is, is ’n beskrywende studie waarin gebruik gemaak is van vraelyste om kwantitatiewe data te versamel. Die monster het bestaand uit 69 vrouens, ouderdom 30 jaar en ouer, wat deelnemers was aan die “Microbicide Kliniese Navorsingsprojek” en wat opvolgbesoeke by klinieke gehad het tussen Julie en Augustus 2008. Die primêre bevinding, wie al ooit vir servikale karsinoom getoets is, is bereik deur die inligting in die laboratorium verslae van die vroue na te gaan. Die sekondêre bevinding was om die deelnemers se kennis en persepsies aangaande servikale karsinoom te toets. Sosio-demografiese faktore wat verband hou met of deelnemers ooit getoets is, is ook ondersoek. Resultate: Van die 69 vrouens, het slegs N=13 (18.8 %) gerapporteer dat hulle ooit getoets is vir servikale kasinoom. Meer as die helfte van die vrouens wat ooit getoets is vir servikale karsinoom het gerapporteer dat ’n gebrek aan inligting ’n weerhoudende faktor was tot die toetse, N=50 (71.4%). Ouer vrouens tussen die ouderdom van 35 – 45, 45 en ouer was minder bereid om te toets in vergelyking met vrouens tussen die ouderdom van 30 tot 34 (OR: 0.06). Dit blyk asof skoolonderrig die kanse op toetsing verhoog, vrouens met primêre skoolopleiding se kanse dat hulle getoets is, is twee keer groter (OR 2.0) en amper drie keer meer (OR 2.67) as ’n vrou sekondêre onderrig of hoër onderrig ontvang het. Meer as die helfte van die respondente dink hulle loop ’n risiko om servikale kanker te kry N=42 (60.8%) en feitlik almal was bereid om hulle te laat toets in die toekoms N=64 (93 %). Bevinding: Die meeste vroue in hierdie studie n=55 (82%) was nog nooit in hul leeftyd getoets vir servikale karsinoom nie terwyl slegs n=14 (18%) ooit getoets was vir servikale karsinoom. Die resultate van hierdie studie kan nie veralgemeen word nie, aangesien die navorsingspopulasie as gevolg van die klein steekproef te klein was. Nietemin is daar ‘n behoefte vir die fasilitering van omvattende gesondheidsopvoeding en die implementering van servikalesmeer toetsing programme. Die resultate van hierdie studie het aangedui dat 60% van die respondente deur professionele gesondheids werkers ingelig is met betrekking tot servikalesmeer toetsing. Gesondheidswerkers behoort ‘n vitale rol te speel in die opvoeding van gemeenskappe in verband met servikale karsinoom en die voordele van hiervan deur alle pasiente wat gesondheidsdienste benut in te lig omtrent servikale karsinoom en ook deur middel van gemeenskaps-uitreikings programme.

The purpose of this dissertation is to explore the creation of a cervical cancer health prevention infographic, geared toward African American women ages 30 to 65, to be potentially used to raise health literacy and influence positive behaviors towards practicing prevention measures—ultimately preventing unnecessary deaths. This dissertation also produced a cervical cancer health prevention infographic prototype for African American Women ages 30 to 65 to be further tested and implemented within future health communication campaigns. Cervical Cancer is both preventable and treatable (if diagnosed during early stages); therefore the amount of individuals dying from the cancer should be minimal. Still, African American Women in this study’s target health population are dying from Cervical Cancer the most. Existing research highlights that social determinants of health (like income, education and literacy) play varying roles as barriers to prevention (Baldwin, 1996; J. L. Davis et al., 2013; Egbert & Parrott, 2001; Ford et al., 2013; McKinnon, Harper, & Moore, 2011; Sung, Alema-Mensah, & Blumenthal, 2002; Williams & Templin, 2013). . This dissertation specifically focuses on targeting the potential to increase health literacy on Cervical Cancer to potentially positively influence prevention uptake. Drawing upon fields like health communication, visual communication and social science research, this research endeavor presents an interdisciplinary approach to potentially solving health communication issue within an at-risk population. The theoretical framework in guiding infographic production for this dissertation was the Health Belief Model, which is widely used in health communication research to assess failure of prevention uptake (du Pré, 2014; Glanz et al., 2005; Maibach & Parrott, 1995; Rosenstock, 2000). The Health Belief Model in conjunction with existing literature regarding health literacy, cultural stigma and relevance in communication campaigns geared toward African American Women ages 30 to 65, infographic content was created and presented to study participants via six interactive focus groups. The focus group methodology of qualitative research allowed for 17 study participants to confidentially engage in dialogue with peers concerning the issue at hand while also helping to create the content hierarchy, enhance and suggest visuals, colors and themes of the proposed infographic. Iterative data analysis approaches allow for constant assessment of study outcomes and themes. This study produces theoretical, practical and methodological implications for future research on the lacking area of scholarly literature. Findings from this dissertation suggest a need to (1) test the proposed infographic for potential national health campaign usage, (2) a need for more long-term collaborative community efforts for continual population access in research on Cervical Cancer prevention, and (3) future assessment of a newer form of focus group research that focuses on incorporation smaller participant groups for increased hands-on interactivity.

Published Article / Worldwide, uterine cervical cancer is one of the most frequently occurring cancers in women, with more than 80% of these cases occurring in developing countries. The South African screening policy and screening program, implemented in 2001, attempt to reduce this incidence of cervical cancer in South Africa. It is essential to treat these women with the best modalities available. This retrospective study focused specifically on the curative potential of radiotherapy administered to patients at the Oncology Department, Bloemfontein, since a new modality of high dose-rate intracavitary brachytherapy was implemented in 1994. Late radiation complications were also investigated.

Gimdos kaklelio vėžys pasaulyje yra antroji, o Lietuvoje ketvirtoji pagal dažnumą moterų onkologinė liga. Pagrindinė gimdos kaklelio vėžio priežastis yra žmogaus papilomos viruso (ŽPV) infekcija gimdos kaklelyje. Vakarų šalyse ikivėžiniams pokyčiams ar vėžinėms ląstelės nustatyti yra naudojamas citologija paremtas Papanicolaou testas (Pap) ir ŽPV DNR testas. Šiuo metu naudojami ŽPV diagnostiniai testai remiasi molekulinės biologijos tyrimo metodais. Tyrimui buvo pasirinktas polimerazės grandininės reakcijos (PGR) metodas, o ne plačiai naudojamas JAV bei Europos kokybės sertifikatus turintis Hybrid Capture 2 (HC2) metodas. PGR yra ypač jautrus, greitas, komerciškai prieinamas metodas, kuriam reikalingas nedidelis tiriamosios medžiagos kiekis, ir kuriuo galima tiksliai identifikuoti ŽPV tipus. HC2 metodas nenustato ŽPV genotipų, galimi klaidingai neigiami rezultatai, nes nėra vidinės kontrolės, o dėl kryžminių reakcijų galimi klaidingai teigiami rezultatai. Naujausi literatūros šaltiniai teigia, kad PGR turi daug perspektyvų ateityje ir manoma, kad ŽPV nustatymo standartas bus 14 DR-ŽPV tyrimas sujungtas su ŽPV-16 ir ŽPV-18 tipų nustatymu. Todėl siekiant ŽPV tyrimams pasirinkti optimaliausią iš Lietuvoje siūlomų komercinių rinkinių Valstybiniame patologijos centre buvo atliekamas šis tyrimas. Įvertinus tyrimų rezultatus, tolesniems tyrimams pasirinktas „Seeplex® HPV4A ACE Screening“ ŽPV nustatymo rinkinys. / Cervical cancer is the second oncological disease in women in the world, and the fourth one in Lithuania. The main cause of the cervical cancer is Human papillomavirus (HPV) infection in the cervix uteri. In order to detect precancerous changes or cancer cells, a Papanicolaou (Pap) test based on cytology and HPV DNA test are used in the Western world. Currently used HPV diagnostic tests are based on molecular biology testing methods. The polymerase chain reaction (PCR) method, not the extensively used Hybrid Capture 2 (HC2) method awarded the certificate of quality by both the USA and Europe, was chosen. PCR is a particularly sensitive, fast, and commercially available method that needs a small quantity of research material and can identify the types of HPV. HC2 method does not detect HPV genotypes, false-negative results are possible because there is no internal control, and due to cross reactions, false-positive results are possible. The newest written sources state that PCR will have much potential in the future and it is thought that HPV detection standard will become 14 HR-HPV test combined with the detection of the types of HPV-16 and HPV-18. Therefore, in order to chose the optimum one for HPV tests from the commercial kits offered in Lithuania, this investigation was carried out in the National Centre of Pathology. Four different HPV diagnostic kits were used for the research. Having evaluated the research results, „Seeplex® HPV4A ACE Screening“ HPV diagnostic kit was... [to full text]

Cervical cancer is the third most common cancer among women worldwide, and the fourth leading cause of cancer mortality. Despite significant declines in the incidence and mortality rates of cervical cancer in Canada, it remains the 4th most common cancer in women aged 20-29 years. In order to gain novel insights into cervical cancer tumourigenesis and clinical outcome, we investigated and characterized the alterations in microRNA (miRNA) expression in this disease. Firstly, we performed global miRNA expression profiling of cervical cancer cell lines (n=3), and patient specimens (n=79). From this analysis, we identified miR-196b to be significantly down-regulated in cervical cancer, and characterized its role in regulating the HOXB7~VEGF axis. The global miRNA expression data also led to the development of a candidate 9-miRNA signature that was prognostic for disease-free survival in patients with cervical cancer, although we were unable to validate this signature in an independent cohort. This report describes important considerations concerning the development and validation of microRNA signatures for cervical cancer. Our investigations also led us to a comparison of three methods for measuring miRNA abundance: the TaqMan Low Density Array, the NanoString nCounter assay, and single-well quantitative real-time PCR. Our findings demonstrated limited concordance between the TLDA and NanoString platforms, although each platform correlated well with PCR, which is considered the gold standard for nucleic acid quantification. Furthermore, we examined biases created by amplification protocols for microarray studies. Our analysis demonstrated that performing a correction using the LTR-method (linear transformation of replicates) could help mitigate, but not completely eliminate such biases. Overall, this report presents insights into the role of miRNAs in cervical cancer, as well as an evaluation of technical considerations concerning miRNA and mRNA expression profiling studies.

A Thesis submitted to The University of Arizona College of Medicine - Phoenix in partial fulfillment of the requirements for the Degree of Doctor of Medicine. / To systematically review all studies examining HPV vaccination acceptability among immigrant and ethnic minority parents and eligible individuals for cervical cancer prevention in the Unites states. MEDLINE/PubMed, Cumulative Index to Nursing and Allied Health Literature, EMBASE, and Cochrane database searches were conducted searching for English language, US‐based studies to examine immigrant and ethnic minority population’s acceptability of HPV vaccination. Thirteen of more than 3,098 potentially relevant articles were included in the final analysis. Results. Latinos were statistically more likely to accept vaccination for both their daughters and sons. Foreign‐born adult Latinas were more accepting of the vaccine than U.S.‐born Latinas after controlling for other variables. Overall African American and Asian American parents were less likely to accept HPV vaccination for their daughters than Hispanic and White parents. Of the African American parents who intended to vaccinate their children the majority were significantly non‐Baptist and had higher levels of education. The majority of Haitian immigrants intended to vaccinate daughters and the rest agreed that they would most likely have their daughters vaccinated if their daughters’ physicians recommended it. More research is needed, particularly in the context of health care provider HPV vaccination recommendation to immigrant and ethnic‐minority populations. Acceptance figures so far suggest that the vaccine is generally well received among Hispanic/Latin and Haitian immigrants, but details of ethnic variations among these groups and a qualitative understanding of lower rates of acceptability among African American and Asian American communities are still being awaited. Despite advances in cervical cancer screening rates in the US, cervical cancer remains disproportionately high among low‐income immigrant and minority women, making this subgroup particularly vulnerable to disparities in screening and its detection. The purpose of this study is to examine the qualitative aspects of institutional and community level interventions of Cervical Intraepithelial Neoplasia (CIN) within the immigrant and refugee populations and the use of HPV vaccination as a prevention method. Combinations of the following keywords/phrases will be used: CIN‐ Cervical Intraepithelial Neoplasia, Cervical diseases, Cervical dysplasia, Refugees, Pap smear, Cervical Cancer Screening, HPV‐ Human Papillomavirus, HPV vaccination, Ethnic minorities, Immigrants. Independent reviews of each article will be conducted to assess the study quality and confirm the accuracy, completeness, and consistency of the abstracted data.

Background: Cervical cancer is the third most common reproductive cancer in the U.S. To date, one report concluded that U.S. Vietnamese women had the highest incidence rate (43.0/100,000). The current study examines whether U.S. Vietnamese women are more likely to have cervical cancer in comparison to Whites, Blacks, Hispanics, American Indians, and other Asian subgroups. Methods: SEER data of cervical cancers diagnosed from 1993-1995 (n = 37,790) was utilized. Using SPSS, chi-square statistics assessed whether Vietnamese women were older and more likely to be married or diagnosed at a later stage. Logistic regression assessed the amount of risk race/ethnicity contributes to stage of diagnosis adjusting for age and martial status. SEER*Stat and U.S. Census data were used to compute age-adjusted incidence and prevalence rates per 100,000 woman-years for cervical cancer. Results: After adjustment, Vietnamese women were more likely to have carcinoma in situ (OR=1.44, p = 0.0 14) compared to white women. The odds of distant stage diagnosis for Vietnamese women was 3.35 times that of whites (p = 0.093). Vietnamese women had greater odds of distant stage diagnosis than other Asian subgroups (OR = 1.43, p = 0.092). The overall age-adjusted incidence rate for invasive cervical cancer for Asian-Pacific Islanders is 6.71100,000 (including Vietnamese) compared to 5.0/100,000 for whites. However, the overall incidence rate for Vietnamese women is 21.4/100,000 compared to 10.4/100,000 for whites. Conclusions: Vietnamese race/ethnicity is associated with cervical cancer diagnosis. Asian subgroups are at varying risk of cervical cancer and should be assessed separately as to not obscure differences.
