Abstract
INTRODUCTION Cervical cancer precursor lesions occur due to persistent infection caused by human papillomavirus (HPV). One of the challenges of the Pap test is detecting lesions at a high risk of evolving into cancer. In this context, differentiating patients at low and high risk of developing cervical cancer becomes necessary. The Swede score, a standardized point system assigned based on colposcopy, is the most commonly used method to evaluate suspicious lesions. However, access to colposcopy is limited in low-income countries. It is, therefore, important to assess the applicability of less costly diagnostic methods in these situations to avoid a late diagnosis of cervical cancer. OBJECTIVE To analyze histological outcomes of cytology tests with atypical squamous cells of undetermined significance (ASC-US and ASC-H) and to compare the performance of the Swede score with and without colposcopy. METHODS The study was approved by the Ethics Committee via Plataforma Brasil (CAAE no. 41958320.6.0000.5259) and conducted by applying colposcopy score and naked eye score to patients with cytology alterations (ASC-US and ASC-H), with posterior analysis of cytological and histological results and comparison between the scores. RESULTS A total of 34 women aged ranging from 24 to 65 years, with results of atypia with undetermined significance (ASC-US and ASC-H), were included in the study. The receiver operating characteristic curve was calculated for the naked eye inspection Swede score. The cut-off of 6 was considered to indicate the best sensitivity and specificity (55.56% and 93.75%, respectively). Then, the positive and negative predictive values were 90.91% and 65.22%, respectively. By increasing the cut-off to 7, specificity increased to 100%. For the colposcopic inspection, a cut-off of 6 indicates better specificity and positive predictive value (both 100%), whereas the negative predictive value was 57.14%. CONCLUSION The correlation between the colposcopic and naked-eye Swede scores was statistically significant (0.82). Further studies with larger samples are important to establish the actual applicability of the naked eye method; however, in the absence of colposcopy, this appears to be an effective and very helpful method to make diagnostic decisions regarding HPV-induced lesions.

Estimating the effect of HIV on cervical cancer elimination in South Africa: Comparative modelling of the impact of vaccination and screening. EClinicalMedicine 2022; 54:101754. [PMID: 36583170 PMCID: PMC9793279 DOI: 10.1016/j.eclinm.2022.101754] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 11/01/2022] [Accepted: 11/03/2022] [Indexed: 11/18/2022] Open
Abstract
Background In 2020, the World Health Organization (WHO) launched its initiative to eliminate cervical cancer as a public health problem. To inform global efforts for countries with high HIV and cervical cancer burden, we assessed the impact of human papillomavirus (HPV) vaccination and cervical cancer screening and treatment in South Africa, on cervical cancer and the potential for achieving elimination before 2120, considering faster HPV disease progression and higher cervical cancer risk among women living with HIV(WLHIV) and HIV interventions. Methods Three independent transmission-dynamic models simulating HIV and HPV infections and disease progression were used to predict the impact on cervical cancer incidence of three scenarios for all women: 1) girls' vaccination (9-14 years old), 2) girls' vaccination plus 1 lifetime cervical screen (at 35 years), and 3) girls' vaccination plus 2 lifetime cervical screens (at 35 and 45 years) and three enhanced scenarios for WLHIV: 4) vaccination of young WLHIV aged 15-24 years, 5) three-yearly cervical screening of WLHIV aged 15-49 years, or 6) both. Vaccination assumed 90% coverage and 100% lifetime protection with the nonavalent vaccine (against HPV-16/18/31/33/45/52/58). Cervical cancer screening assumed HPV testing with uptake increasing from 45% (2023), 70% (2030) to 90% (2045+). We also assumed that UNAIDS 90-90-90 HIV treatment and 70% male circumcision targets are reached by 2030. We examined three elimination thresholds: age-standardised cervical cancer incidence rates below 4 or 10 per 100,000 women-years, and >85% reduction in cervical cancer incidence rate. We conducted sensitivity analyses and presented the median age-standardised predictions of outcomes of the three models (minimum-maximum across models). Findings Girls' vaccination could reduce age-standardised cervical cancer incidence from a median of 47.6 (40.9-79.2) in 2020 to 4.5 (3.2-6.3) per 100,000 women-years by 2120, averting on average ∼4% and ∼46% of age-standardised cumulative cervical cancer cases over 25 and 100 years, respectively, compared to the basecase. Adding 2 lifetime screens helped achieve elimination over the century among all women (2120 cervical cancer incidence: 3.6 (1.9-3.6) per 100,000 women-years), but not among WLHIV (10.8 (5.3-11.6)), and averted more cumulative cancer cases overall (∼45% over 25 years and ∼61% over 100 years compared to basecase) than girls' vaccination alone. Adding three-yearly cervical screening among WLHIV (to girls' vaccination and 2 lifetime cervical screens) further reduced age-standardised cervical cancer incidence to 3.3 (1.8-3.6) per 100,000 women-years overall and to 5.2 (3.9-8.5) among WLHIV by 2120 and averted on average 12-13% additional cumulative cancer cases among all women and 21-24% among WLHIV than girls' vaccination and 2 lifetime cervical screens over 25 years or longer. Long-term vaccine protection and using the nonavalent vaccine was required for elimination. Interpretation High HPV vaccination coverage of girls and 2 lifetime cervical screens could eliminate cervical cancer among women overall in South Africa by the end of the century and substantially decrease cases among all women and WLHIV over the short and medium term. Cervical cancer elimination in WLHIV would likely require enhanced prevention strategies for WLHIV. Screening of WLHIV remains an important strategy to reduce incidence and alleviate disparities in cervical cancer burden between women with and without HIV, despite HIV interventions scale-up.

Costs and cost-effectiveness of cervical cancer screening strategies in women living with HIV in Burkina Faso: The HPV in Africa Research Partnership (HARP) study. PLoS One 2021; 16:e0248832. [PMID: 33765011 PMCID: PMC7993811 DOI: 10.1371/journal.pone.0248832] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Accepted: 03/05/2021] [Indexed: 12/24/2022] Open
Abstract
Introduction This study estimated the costs and incremental cost per case detected of screening strategies for high-grade cervical intraepithelial neoplasia (CIN2+) in women living with HIV (WLHIV) attending HIV clinics in Burkina Faso. Methods The direct healthcare provider costs of screening tests (visual inspection with acetic acid (VIA), VIA combined visual inspection with Lugol’s iodine (VIA/VILI), cytology and a rapid HPV DNA test (careHPV)) and confirmatory tests (colposcopy, directed biopsy and systematic four-quadrant (4Q) biopsy) were collected alongside the HPV in Africa Research Partnership (HARP) study. A model was developed for a hypothetical cohort of 1000 WLHIV using data on CIN2+ prevalence and the sensitivity of the screening tests. Costs are reported in USD (2019). Results The study enrolled 554 WLHIV with median age 36 years (inter-quartile range, 31–41) and CIN2+ prevalence of 5.8%. The average cost per screening test ranged from US$3.2 for VIA to US$24.8 for cytology. Compared to VIA alone, the incremental cost per CIN2+ case detected was US$48 for VIA/VILI and US$814 for careHPV. Despite higher costs, careHPV was more sensitive for CIN2+ cases detected compared to VIA/VILI (97% and 56%, respectively). The cost of colposcopy was US$6.6 per person while directed biopsy was US$33.0 and 4Q biopsy was US$48.0. Conclusion Depending on the willingness to pay for the detection of a case of cervical cancer, decision makers in Burkina Faso can consider a variety of cervical cancer screening strategies for WLHIV. While careHPV is more costly, it has the potential to be cost-effective depending on the willingness to pay threshold. Future research should explore the lifetime costs and benefits of cervical cancer screening to enable comparisons with interventions for other diseases.

Re-thinking breast and cervical cancer preventive campaigns in developing countries: the case for interventions at high schools. BMC Public Health 2019; 19:503.

Abstract
BACKGROUND The negative impact of cervical and breast cancers in low and lower-middle income countries are worsening, and, along with other non-communicable diseases, occur disproportionately in these resource-limited economies. Most preventive approaches to these cancers require government funding, but few countries with the most at-risk population can afford government-sponsored universal vaccination, screening, diagnostic and treatment programmes, which, along with socioeconomic issues, contribute to the poor outcomes in these mostly developing countries. An urgent need exists, therefore, to find an effective, affordable, cost-effective, culturally-acceptable and sustainable way of reducing these cancers. This paper advocates a re-thinking in the current preventive campaigns. MAIN BODY Using evidence provided by recently-published papers, a case is made for enlightenment campaigns to primarily target teenagers (boys and girls) in high schools of developing countries. Inclusions into the schools' academic curricula are the recommended approach, given that both cancers take hold on populations within that age bracket. This approach, if adopted, may be the only accessible, affordable and realistic approach that gives millions of women in low and lower-middle income countries the chance at survival. Empowering them early instils the self-awareness and confidence necessary for young adults to take charge of their own health. The acquired knowledge, in turn, helps them adopt positive attitudes and preventive behaviours that will, ultimately, prolong their lives. CONCLUSION The recommended approach offers governments and concerned stakeholders an evidence-based option that allows them to deliver cost-effective and sustainable life-saving interventions, while hoping to get around the bottlenecks that limit the large scale implementation of other effective but capital-intensive strategies.

Abstract
OBJECTIVE To ascertain the level of awareness and attitudes towards cervical cancer among secondary school students in Nigeria. METHOD Cross-sectional survey of 432 female senior secondary school students in south-eastern Nigeria. RESULTS A total of 321 (74.3%) responses were valid; 42.7% had heard of cervical cancer, 32.8% of screening, 23.2% of Pap smears and 22.0% of HPV/HPV vaccinations. No widely available reliable source of information exists. General knowledge about Pap smears (41.8%) and HPV (43.1%) was poor, as was specific knowledge about their benefits, timing and frequency, and about HPV vaccinations, but associated attitudes were moderately positive at 60.2% and 65.1%, respectively. Awareness of cervical cancers increases knowledge about when to start screening (OR = 2.30; P = 0.02) and about early symptoms of cervical cancer (OR = 2.56; P = 0.001). CONCLUSION Overall knowledge of cervical cancer is poor, but attitudes are positive. Awareness campaigns are therefore necessary, and are expected to be effective. Campaigns should target teenage females, and commencing teaching in high schools of developing countries, through materials included in their academic curricula, is recommended.

Abstract
INTRODUCTION Performing brachytherapy on female patients with gynaecological cancer is a sensitive procedure, apart from it being an intricate investigation. The aim of this study: establishing gynaecological cancer patients' expectations, experiences and understandings of the high dose-rate brachytherapy treatment procedure. Exploring these patients' life-worlds provides further insights into improving their preparedness and experiences. METHODS A qualitative research design with a descriptive phenomenological research approach was used. Recruitment entailed using purposive sampling. To obtain rich insights into the lived experiences, data was acquired through semi-structured interviews until data saturation. RESULTS Major challenges were experienced with mixed thoughts and feelings, from negative trauma to desires being fulfilled. These patients should have received more information regarding their upcoming brachytherapy treatment. This would have alleviated some of their fears and anxieties, which would in turn have provided them with a better brachytherapy treatment experience. Envisaged outcomes and desires are used to cope. Patients influence each other negatively, so they rather wanted to "see for themselves". CONCLUSION Despite some disappointments and negative experiences throughout the brachytherapy continuum, the patients were left with a positive outlook, saying that it is an excellent and necessary treatment. Further studies should be done to elaborate on fulfilments of recommendations in the brachytherapy department of radiation oncology.

Abstract
BACKGROUND Cervical cancer is the most prevalent malignancy in sub-Saharan Africa (SSA) with many women only seeking professional help when they are experiencing symptoms, implying late-stage malignancy and higher mortality rates. This ecological study assesses population-level exposures of SSA women to the numerous risk factors for HPV infection and cervical cancer, against late-stage presentation of cervical cancer. MATERIALS AND METHOD A literature review revealed the relevant risk factors in SSA. Open-access databases were mined for variables closely representing each risk factor. A proxy for late-stage presentation was used (ratio of incidence-to-mortality, IMR), and gathered from IARC's GLOBOCAN 2012 database. Variables showing significant correlation to the IMR were used in stepwise multiple regression to quantify their effect on the IMR. RESULTS Countries with high cervical cancer mortality rates relative to their incidence have an IMR nearer one, suggesting a larger proportion of late-stage presentation. Western Africa had the lowest median IMR (1.463), followed by Eastern Africa (IMR = 1.595) and Central Africa (IMR = 1.675), whereas Southern Africa had the highest median IMR (1.761). Variables selected for the final model explain 65.2% of changes seen in the IMR. Significant predictors of IMR were GDP (coefficient = 2.189 × 10-6, p = 0.064), HIV infection (-1.936 × 10-3, p = 0.095), not using a condom (-1.347 × 10-3, p = 0.013), high parity (-1.744 × 10-2, p = 0.008), and no formal education (-1.311 × 10-3, p < 0.001). CONCLUSION Using an IMR enables identification of factors predicting late-stage cervical cancer in SSA including: GDP, HIV infection, not using a condom, high parity and no formal education.

Abstract
BACKGROUND Effective female education on cervical cancer prevention has been shown to increase awareness and uptake of screening. However, sustaining increase in uptake poses a challenge to control efforts. Peer health education has been used as an effective tool for ensuring sustained behavior change. This study was undertaken to assess the effectiveness of peer health education on perception, willingness to screen and uptake of cervical cancer screening by women. METHODS A before and after intervention study was undertaken in 2 urban cities in Enugu state, Nigeria among women of reproductive age attending women's meeting in Anglican churches. Multistage sampling was used to select 300 women. Peer health education was provided once monthly for 3 consecutive sessions over a period of 3 months. Data was collected at baseline and after the intervention using pre-tested questionnaires. Descriptive statistics and tests of significance of observed differences and associations were done at p-value of <0.05. RESULTS Statistical significant difference was observed in participants' individual risk perception for cervical cancer and perception of benefits of early detection through screening. Practice of screening for cervical cancer increased by 6.8% and the observed difference was statistically significant (p = 0.02). This was significantly associated with marital status, level of education, employment status and parity (p < 0.05). CONCLUSION Peer health education is an effective strategy for increasing women's perception of benefits of early detection of cervical cancer through screening. It is also effective for increasing their practice of screening for cervical cancer.

Abstract
BACKGROUND Cervical cancer is one of the major diseases that affect women of child bearing age. Its main cause is the human papilloma virus; although, other associated factors have been evidenced to increase its risk. Pap-smear screening and vaccination which has been shown to be successful in reducing the incidence and prevalence of the disease in developed countries, has been neglected in developing countries due to lack of knowledge, misconceptions, and cultural beliefs. MATERIALS AND METHODS A cross-sectional study involving only female Sub-Saharan Africa (SSA) students in a UK university setting. RESULTS One hundred and eighty-six (42%) African female students were recruited from the 442 SSA students attending one of the major Universities in the UK. Seventy-one (38.2%) of the students were aware of cervical screening, but only 20 (10.8%) reported having knowledge of cervical cancer. A small percentage of about 26.9% (50 Students) were already part of this screening program; although, 81 (43.5%) showed willingness to participate in future screening programs. More so, it was evident that student's perception was dependent on their experience of the disease (P = 000) just as their participation in screening program was dependent on their awareness level (P ≤ 0.01). CONCLUSION Female African students from the SSA region have poor knowledge of the disease which influenced their attitude toward screening. More needs to be carried out to increase awareness and uptake of screening within the school environment as university setting provides a viable platform to promote healthy behavior. Résumé Contexte: Le cancer du col de l'utérus est l'une des principales maladies qui touchent les femmes en âge de procréer. Sa principale cause est le virus du papillome humain; Bien que, d'autres facteurs associés ont été mis en évidence pour augmenter son risque. Le dépistage du Pap et la vaccination, qui s'est avéré efficace pour réduire l'incidence et la prévalence de la maladie dans les pays développés, a été négligé dans les pays en développement en raison du manque de connaissances, d'idées fausses et de croyances culturelles. Matériel et Méthodes: Une étude transversale impliquant seulement des étudiantes d'Afrique subsaharienne (SSA) dans un université britannique. Résultats: Cent quatre-vingt-six (42%) étudiantes africaines ont été recrutées parmi les 442 étudiants SSA fréquentant l'une des plus grandes universités du Royaume-Uni. Soixante et onze (38,2%) des étudiants étaient au courant du dépistage du cancer du col, mais seulement 20 (10,8%) ont déclaré avoir une connaissance du cancer du col de l'utérus. Un faible pourcentage d'environ 26,9% (50 étudiants)Font déjà partie de ce programme de dépistage; 81 (43,5%) se sont montrés disposés à participer à de futurs programmes de dépistage. De plus, il était évident que la perception des étudiants dépendait de leur expérience de la maladie (P = 000), tout comme leur participation au programme de dépistage dépendait de leur niveau de sensibilisation (P ≤ 0,01). CONCLUSION Les étudiantes africaines de la région de l'Afrique subsaharienne connaissent mal la maladie et ont influencé leur attitude envers le dépistage. Davantage de mesures doivent être prises pour accroître la sensibilisation et l'adoption du dépistage dans l'environnement scolaire, car le cadre universitaire constitue une plate-forme viable pour promouvoir un comportement sain.

Abstract
Background In South Africa, cervical cancer remains among the most common cancers and a leading cause of cancer death. Co-infection with HIV increases the risk of developing cervical pre-cancer and cancer. We analysed National Health Laboratory Service cervical cytology data to investigate geographic variations of Pap smear coverage, quality, and high grade lesions. Methods Facility-level data were extracted from the NHLS for April 2013–March 2014. We present results and choropleth maps detailing coverage, adequacy and high-grade Pap smear cytology abnormalities defined as Pap smears suspicious for invasive carcinoma, high-grade squamous intraepithelial lesions (HSIL) or atypical squamous cells: cannot exclude HSIL (ASC-H). Results 4,562 facilities submitted 791,067 cytology slides. The interquartile range (IQR) for Pap smear coverage among HIV-infected women was 26–41%; similar to coverage in women aged 30 and older (IQR: 26–42%). 6/52 districts had adequacy rates above the national standard (70%) and 2/52 districts had adequacy rates below 35%. We observed marked variation in Pap smear abnormalities across the country, with the proportion of high-grade cytology abnormalities ≥0.3% in 17/52 districts. Conclusion Using district-level choropleth maps, we are able to display variations in Pap smear coverage, quality, and results across South Africa. This approach may be used to improve resource allocation, achieving better equity in cervical cancer prevention.

Abstract
Paper diagnostics have successfully been employed to detect the presence of antigens or small molecules in clinical samples through immunoassays; however, the detection of many disease targets relies on the much higher sensitivity and specificity achieved via nucleic acid amplification tests (NAAT). The steps involved in NAAT have recently begun to be explored in paper matrices, and our group, among others, has reported on paper-based extraction, amplification, and detection of DNA and RNA targets. Here, we integrate these paper-based NAAT steps into a single paperfluidic chip in a modular, foldable system that allows for fully integrated fluidic handling from sample to result. We showcase the functionality of the chip by combining nucleic acid isolation, isothermal amplification, and lateral flow detection of human papillomavirus (HPV) 16 DNA directly from crude cervical specimens in less than 1 hour for rapid, early detection of cervical cancer. The chip is made entirely of paper and adhesive sheets, making it low-cost, portable, and disposable, and offering the potential for a point-of-care molecular diagnostic platform even in remote and resource-limited settings.

Abstract
BACKGROUND In South Africa, the prevalence of oncogenic Human Papillomavirus (HPV) may be as high as 64%, and cervical cancer is the leading cause of cancer-related death among women. The development of efficacious prophylactic vaccines has provided an opportunity for primary prevention. Given the importance of psycho-social forces in vaccine uptake, we sought to elucidate factors influencing HPV vaccination among a sample of low-income South African adolescents receiving the vaccine for the first time in Soweto. METHODS The HPV vaccine was introduced to adolescents in low-income townships throughout South Africa as part of a nationwide trial to understand adolescent involvement in future vaccine research targeting human immunodeficiency virus (HIV). We performed in-depth semi-structured interviews with purposively-sampled adolescents and their care providers to understand what forces shaped HPV vaccine uptake. Interviews were recorded, transcribed, translated, and examined using thematic analysis. RESULTS Of 224 adolescents recruited, 201 initiated the vaccine; 192 (95.5%) received a second immunization; and 164 (81.6%) completed three doses. In our qualitative study of 39 adolescent-caregiver dyads, we found that factors driving vaccine uptake reflected a socio-cultural backdrop of high HIV endemnicity, sexual violence, poverty, and an abundance of female-headed households. Adolescents exercised a high level of autonomy and often initiated decision-making. Healthcare providers and peers provided support and guidance that was absent at home. The impact of the HIV epidemic on decision-making was substantial, leading participants to mistakenly conflate HPV and HIV. CONCLUSIONS In a setting of perceived rampant sexual violence and epidemic levels of HIV, adolescents and caregivers sought to decrease harm by seeking a vaccine targeting a sexually transmitted infection (STI). Despite careful consenting, there was confusion regarding the vaccine's target. Future interventions promoting STI vaccines will need to provide substantial information for participants, particularly adolescents who may exercise a significant level of autonomy in decision-making.

Abstract
South Africa bears the greatest burden of HIV infection globally with the most infected people living in KwaZulu-Natal (KZN). Decentralised medical care for HIV positive patients and antiretroviral therapy (ART) delivery to primary health care facilities were proposed nationally to achieve adequate ART coverage for patients in need of treatment. This study described the HIV positive patients who accessed medical care and were initiated on ART at two existing government Primary Health Care (PHC) clinics with no added donor support, in Ilembe, KZN. This was an observational descriptive study of ART initiation from 01 April 2008 to 30 April 2009. Data were collected from clinical records kept on site. HIV Testing and the pre-ART programmes which consisted of medical care prior to ART initiation are briefly described. Socio-economic, demographic and clinical characteristics of patients who were initiated on ART were sampled and described. A minority (2.95%) of the study population tested for HIV of which 36.0% tested positive. Majority (60.0%) of patients who joined the pre-ART programme care did not return. The ART sample consisted of 375 patients of whom 65.0% were women, 85.9% were unmarried, 61.6% were unemployed and 50.4% had a secondary level of education. Tuberculosis (TB) prevalence and incidence at ART initiation were 22.1% and 14.7% respectively. The prevalence of Syphilis and Hepatitis B co-infections were 13.1% and 8.6 % respectively. Two thirds of female patients (66.4%) received a Pap smear result of which the majority (62.3%) were abnormal. Uptake for HIV testing followed by relevant CD4 testing was poor. High TB, Hepatitis B and Syphilis co-infection was noted amongst patients initiated on ART. Cervical cancer screening must be intensified. Although ART initiation with no added external resources was successful, record keeping was suboptimal.Suid-Afrika dra die grootste las van MIV-infeksie ter wêreld met die meeste besmette mense in KwaZulu-Natal (KZN). Gedesentraliseerde mediese sorg vir MIV-positiewe pasiënte en dienslewering van antiretrovirale terapie (ART) aan primêre gesondheidsorg- fasiliteite is nasionaal voorgestel om optimale ART-behandeling aan behoeftige te verskaf. Hierdie studie beskryf MIV-positiewe pasiënte wat ART-behandeling ontvang by twee bestaande Primêre Gesondheidsorgklinieke (PGS) in Ilembe, KZN sonder enige bykomende skenkerondersteuning. Waarnemingstegnieke is in die studie gebruik om ART-bekendstelling van 01 April 2008 tot 30 April 2009 te bestudeer. Data van kliniese rekords wat op die perseel gehou is, is ingesamel. MIV-toetsing en mediese behandelingsprogramme voor die bekendstelling van ART word kortliks beskryf. Sosio-ekonomiese, demografiese en kliniese eienskappe van pasiënte wat aan ART bekendgestel is, is versamel en beskryf. Minimum (2.95%) respondente aan die studie is vir MIV getoets, waarvan 36.0% positief getoets het. Die Meerderheid (60.0%) van pasiënte wat by die voorafgaande ART-sorgprogram aangesluit het, het nie terugkeer nie. Die ART-steekproef het bestaan uit 375 pasiënte waarvan 65.0% vroue was, 85.9% was ongetroud, 61.6% was werkloos en 50.4% het ’n sekondêre vlak van onderwys gehad. Die bestaan (reeds onder behandeling) en voorkoms (diagnose tydens bekendstelling van die ART-program) van Tuberkulose (TB) tydens ART-bekendstelling was 22.1% en 14.7% onderskeidelik. Die voorkoms van sifilis- en hepatitis B-infeksies was 13.1% en 8.6% onderskeidelik. Twee derdes van die vroulike pasiënte (66.4%) het ’n Papsmeer ondergaan, waarvan die meerderheid (62.3%) se uitslae abnormaal was. Die begrip vir MIV-toetsing gevolg deur toepaslike CD4-toetsing was swak. Hoë TB-, Hepatitis B- en sifilisinfeksies was by pasiënte aangeteken wat met ART-behandeling begin het. Ondersoeke vir servikale kanker moet verhoog word. Hoewel die ART-bekendstelling met geen toegevoegde eksterne hulpbronne suksesvol was, was rekordhouding nie optimaal nie.

Abstract
OBJECTIVE To evaluate an accurate, affordable, and feasible method to screen and treat HIV-infected women so that cervical cancer can be prevented among them. DESIGN A cross-sectional study was conducted in India in which eligible HIV-infected women underwent visual inspection with acetic acid (VIA), visual inspection with Lugol's iodine (VILI), cytology, human papillomavirus (HPV) testing, and colposcopy. METHODS We screened women with cytology, HPV testing, VIA, and VILI. All screened women had colposcopy and women with colposcopic abnormalities had directed biopsies. Women with suspected cervical intraepithelial neoplasia (CIN) on colposcopy were treated with cold coagulation or loop excision. Sensitivity, specificity, and predictive values of the screening tests were calculated. RESULTS : Among 1128 women screened, 55 (4.9%) had CIN2-3 lesions. Sensitivity for VIA, VILI, cytology at atypical squamous cells of undetermined significance (ASCUS) threshold and HPV testing was 83.6, 89.1, 63.3, and 94.6%, and specificity was 88.8, 89.3, 94.5, and 77.4%, respectively, in detecting CIN2/3 lesions. Cytology had significantly lower sensitivity and higher specificity than VIA, VILI, and HPV testing. Sequential testing with VIA/VILI, HPV testing/VIA, HPV testing/VILI, and HPV testing/VIA/VILI had more balanced sensitivity and specificity than the single tests. Cold coagulation was well tolerated and cured 80% of CIN2-3 based on preliminary results at 6-month to 1-year follow-up periods. CONCLUSIONS Sequential testing with VIA and VILI is the most feasible screening approach for cervical cancer screening in HIV-infected women in low-resource countries. When HPV testing becomes feasible and affordable, HPV testing followed by VIA/VILI may be considered.

Abstract
BACKGROUND Cervical cancer is a leading cause of death from cancer among women in low-resource settings, affecting women at a time of life when they are critical to social and economic stability. In addition, the economic burden is important for policy formulation. The aim of this study is to estimate patient side cost and to determine predictors of its variation for the treatment of cervical cancer. METHODS Analytic cross sectional study involving 227 cervical cancer cases at Tikur Anbessa Hospital, Ethiopia was conducted. Cost estimation was based on patients' perspective and using the prevalence-based model as a time frame. Productivity losses were estimated from lost working days. RESULTS The mean outpatient cost per patient for cervical cancer was $407.2 (Median = $206.9). Direct outpatient cost (Mean = $334.2) takes the largest share compared with the indirect counterpart ($150). The outpatient cost for half of the respondent falls in a range between $93.7 and $478. The mean inpatient cost for hospitalized patients was $404.4. The average direct inpatient cost was $329 (74% medical costs and 26% non medical costs). The mean value for total inpatient cost for half of the respondents was in the range of $133.5 and $493.9. For every additional day of inpatient hospital stay, there is a daily incremental inpatient cost of $4.2. CONCLUSION As has been found in other studies, our findings revealed that cervical cancer creates an immense financial burden on patients. Primary prevention measures, vaccination against HPV and screening, should be initiated and expanded to reduce morbidity from cervical cancer and subsequent costs in both human lives and money resources. Control of co-morbidity and complication should be emphasized during management of cervical cancer patients. Capacitating regional hospitals and provision of low cost or fee exemption schemes should be arranged and strengthened.

Abstract
Human immunodeficiency virus (HIV)-infected women in India and other developing country settings are living longer on antiretroviral therapy, yet their risk for human papillomavirus (HPV)-induced cervical cancer remains unabated because of lack of cost-effective and accurate secondary prevention methods. Visual inspection after application of dilute acetic acid on the cervix (VIA) has not been adequately studied against the current standard: conventional cervical cytology (Pap smears) among HIV-infected women. We evaluated 303 nonpregnant HIV-infected women in Pune, India, by simultaneous and independent screening with VIA and cervical cytology with disease ascertainment by colposcopy and histopathology. At the cervical intraepithelial neoplasia (CIN2+) disease threshold, the sensitivity, specificity and positive and negative predictive value estimates of VIA were 80, 82.6, 47.6 and 95.4% respectively, compared to 60.5, 59.6, 22.4 and 88.7% for the atypical squamous cells of undetermined significance or severe (ASCUS+) cutoff on cytology, 60.5, 64.6, 24.8 and 89.4% for the low-grade squamous intraepithelial cells or severe (LSIL+) cutoff on cytology and 20.9, 96.0, 50.0 and 86.3% for high-grade squamous intraepithelial lesion or severe (HSIL+) cutoff on cytology. A similar pattern of results was found for women with the presence of carcinogenic HPV-positive CIN2+ disease, as well as for women with CD4+ cell counts <200 and <350 μL(-1) . Overall, VIA performed better than cytology in this study with biologically rigorous endpoints and without verification bias, suggesting that VIA is a practical and useful alternative or adjunctive screening test for HIV-infected women. Implementing VIA-based screening within HIV/acquired immunodeficiency syndrome care programs may provide an easy and practical means of complementing the highly anticipated low-cost HPV-based rapid screening tests in the near future, thereby contributing to improve program effectiveness of screening.

Abstract
The notion that adolescent daughters can provide their mothers with health information that could actually impact the mothers' behavior is a novel area of health promotion research. The goal of this study is to explore the reasons why adolescent daughters would give their mothers cervical cancer information, and why mothers would have the intent to listen to advice to obtain a Pap smear. We randomly selected and interviewed 157 mother and daughter dyads in Cape Town, South Africa. Almost one-fourth of mothers (22%) indicated never having had a Pap smear, while 92% of their daughters said their mother has never talked to them about cervical cancer or a Pap smear. Willingness of daughters to ask their mothers to obtain a Pap smear was high (80%). Motivations included the important health benefit and the sense of responsibility to share life saving information. Most mothers said they would definitely obtain a Pap smear when advised by their daughter (74%), while 25% said they would have to think about it and 1% said they would not listen. Mothers' main motivations included the direct health benefit and a strong sense of duty and responsibility to listen to her daughter. This study provides important information about the reasons why an upward (child to parent) health intervention may be feasible. The values of duty and responsibility, especially as it manifests within the family, hold promise for informing health promotion interventions directed at multiple generations.

Abstract
Cancer incidence rates and patterns are reported for a rural population, living in the Eastern Cape Province of South Africa for the period 1998-2002. The population-based cancer registry has operated for 20 years, using both active and passive methods for case finding, through collaborations with 19 health facilities: 11 district hospitals, 7 referral hospitals and 1 regional laboratory. The age standardized incidence rates for all cancers were 73.1 per 100,000 in males and 64.1 per 100,000 in females. The leading top 5 cancers for males were oesophagus (32.7 per 100,000), lung (5.8 per 100,000), prostate (4.4 per 100,000), liver (4.4 per 100,000) and larynx (2.5 per 100,000) whereas for females they were cervix (21.7 per 100,000), oesophagus (20.2 per 100,000), breast (7.5 per 100,000), ovary (0.9 per 100,000) and liver (0.9 per 100,000). The incidence of Kaposi sarcoma was low, and higher for males (1.6 per 100,000) than females (0.3 per 100,000). Lung cancer in both males and females was relatively low compared to the high incidence of oesophagus cancer.
