ABSTRACT: Background
Screening programs play an important role in a comprehensive strategy to prevent cervical cancer, a leading cause of death among women of reproductive age. Unfortunately, there is a dearth of information about rates of cervical cancer testing, particularly in Eastern Europe and Central Asia where levels of cervical cancer are among the highest in the WHO European Region. The purpose of this article is to report on the lifetime prevalence of cervical cancer testing among females aged 30-49 years from across the WHO European region, and to describe high-level geographic and socioeconomic differences.Methods
We used data from the European Health Information Survey and the WHO STEPwise approach to Surveillance survey to calculate the proportions of women who were tested for cervical cancer.Results
The percentage of tested women ranged from 11.7% in Azerbaijan to 98.4% in Finland, with the lowest percentages observed in Azerbaijan, Tajikistan and Uzbekistan. Testing was lower in Eastern Europe (compared to Western Europe), among low-income countries and among women with lower levels of education.Conclusion
Effective cervical cancer screening programs are one part of a larger strategy, which must also include national scale-up of human papilloma virus vaccination, screening and treatment.

Project description:ObjectiveTo evaluate the adoption of HPV testing and recommended extended cervical cancer screening intervals in clinical practice, we described yearly uptake of Pap/HPV cotesting and estimated length of time between normal screens by patient characteristics.MethodsWe examined 55,575 Pap/HPV records from 27,035 women aged 30-65 years from the Johns Hopkins Hospital Pathology Data System between 2006 and 2013. Cotest uptake and median times to next screening test for cotests and cytology only were calculated. Adjusted hazard ratios were estimated using Cox proportional hazards models, with random effects adjustment for clustering within clinic.ResultsCotest usage increased from < 10% in 2006 to 78% in 2013. The median time to next screening test following normal cytology alone remained constant around 1.5 years. Screening intervals following a dual-negative cotest increased from 1.5 years in 2006/2007 to 2.5 years in 2010, coincident with increases in the proportion of women cotested. Intervals following a dual negative cotest were longer among Medicare patients (3 years) compared with privately insured women (2.5 years), and shorter among black (2 years) compared with white women (2.8 years).ConclusionBy mid-2013 we observed broad adoption of Pap/HPV cotesting in routine screening in a large academic medical center. Increased screening intervals were observed only among cotested women, while those screened by cytology alone continued to be screened almost annually. The influence of different combinations of race and insurance on screening intervals should be further evaluated to ensure balance of screening risks and benefits in the U.S.Population

Project description:BackgroundCervical cancer screening guidelines for women aged ?30 years allow for co-testing or primary cytology testing. Our objective was to determine the test characteristics and costs associated with Cytology, HPV and Co-testing screening strategies.Main methodsRetrospective cohort study of women undergoing cervical cancer screening with both cytology and HPV (Hybrid Capture 2) testing from 2004 to 2010 in an integrated health system. The electronic health record was used to identify women aged ?30 years who had co-testing. Unsatisfactory or unavailable test results and incorrectly ordered tests were excluded. The main outcome was biopsy-proven cervical intraepithelial neoplasia grade 3 or higher (CIN3+).Key resultsThe final cohort consisted of 99,549 women. Subjects were mostly white (78.4 %), married (70.7 %), never smokers (61.3 %) and with private insurance (86.1 %). Overall, 5121 (5.1 %) tested positive for HPV and 6115 (6.1 %) had cytology ? ASCUS; 1681 had both and underwent colposcopy and 310 (0.3 %) had CIN3+. Sensitivity for CIN3+ was 91.9 % for Primary Cytology, 99.4 % for Co-testing, and 94.8 % for Primary HPV; specificity was 97.3 % for Co-testing and Primary Cytology and 97.9 % for Primary HPV. Over a 3-year screening interval, Primary HPV detected more cases of CIN3+ and was less expensive than Primary Cytology. Co-testing detected 14 more cases of CIN3+ than Primary HPV, but required an additional 100,277 cytology tests and 566 colposcopies at an added cost of $2.38 million, or $170,096 per additional case detected.ConclusionsPrimary HPV was more effective and less expensive than Primary Cytology. Primary HPV screening appears to represent a cost-effective alternative to Co-testing.

Project description:In women aged ≥ 30 years, Human Papillomavirus testing will replace cytology for primary cervical screening. We compared Hybrid Capture 2 (HC2), cobas, CLART, and APTIMA HPV assays with cytology on 2869 SurePath samples from women undergoing routine screening at 30-65 years in Copenhagen, Denmark. Women with cytological abnormalities were managed according to routine recommendations, with 92% completeness. Those with cytology-normal/HPV-positive samples (on any of the four assays) were invited for repeated cytology and HPV testing in 1.5 year, and 58% had additional testing. HPV testing detected more ≥ CIN3 than cytology (HC2: 35, cobas, CLART: 37, APTIMA: 34, cytology: 31), although statistically the differences were not significant. Cobas and CLART detected significantly more ≥ CIN2 than cytology (cobas, CLART: 49, cytology: 39). The proportion of women with false-positive test results (positive test results without ≥ CIN3) varied between 3.3% with cytology and 14.9% with cobas. All HPV assays led to significantly more false-positive tests, whereas compared to HC2 cobas and CLART were associated with a significantly higher and APTIMA with a significantly lower proportion. Detection of CIN1 was particularly increased for the three DNA assays. With APTIMA combined with cytological triage, about 20% more women were referred for colposcopy than with cytology screening. With the three DNA assays, the increase was ≥ 50%. The number of women with repeated testing was twice as high with APTIMA and almost five times as high with cobas compared to cytology. To our knowledge, Horizon was the only study set in routine practice that compared more than two HPV assays in the same women while also ascertaining the histological status of women with normal cytology/HPV-positive test results. HPV-based screening of Danish women aged 30-65 detected more high-grade CIN but decreased the screening specificity, and increased the demand for additional testing.

Project description:BackgroundHuman papillomavirus (HPV) infection is considered as the major risk factor for the development of cervical cancer, second most frequent cancer in Ethiopia. However, the magnitude of the problem and the associated factors remain unrevealed in the Amhara region. This study aimed to determine the prevalence of HPV infection and factors contributing to the progression of HPV infection to cervical cancer.MethodsFacility-based cross-sectional study design was employed among women aged 21 to 49 years of age who came for routine cervical cancer screening to 4 randomly selected hospitals (2 general and 2 referral) of Amhara region from May to October, 2019. The sample size was calculated by using the single population proportion formula, proportionated to hospitals, and women were recruited consecutively. Socio demographic and clinical data were collected using a pretested questionnaire and detection of HPV infection was done using HPV test (OncoE6TM Cervical Test) specific to HPV16/18 in cervical swabs. Visual inspection with acetic acid (VIA) was used to determine cervical lesions (precancerous and cancerous). Descriptive statistics and bivariate and multivariate logistic regression were used to describe HR-HPV and cervical lesions burden and association between HR-HPV, and cervical lesions and potential risk factors.ResultsAmong 337 women 21 to 49 years (median age of 35 years ±SD = 7.1 years) of age enrolled in the study, The overall prevalence of oncogenic HPVs (HPV16/18) and the VIA-positivity rate, possible an indicative of cervical lesions, were 7.1% and 13.1%, respectively. Logistic regression analysis showed a significant association between early age of first sexual intercourse (COR = 2.26; 95% CI: 1.0-5.05) and level of education (COR = 0.31; 95% CI: 0.12-0.78) with cervical lesions. Higher odds of HPV positivity (COR = 1.56; 95% CI: 0.59-4.11, p = 0.36) and VIA positivity (COR = 1.39; 95% CI: 0.64-3.00, p = 0.39) were observed among participants who had a history of sexually transmitted illnesses (STIs).ConclusionsThere was a relatively low prevalence of oncogenic HPV 16/18 and VIA-positivity in women attending four hospitals in the Amhara Region. Early age sexual contact, high parity, and being uneducated/low level of education were independently associated factors with HR-HPV infection and development of cervical lesions, highlighting the importance of prioritizing the limited HPV testing to those risk groups.

Project description:BackgroundWorldwide cervical cancer is the third most common malignancy in women. It usually arises from the cervical area which is susceptible to Human Papilloma virus induced malignancy changes. In low-resource setting visual inspection with acetic acid (VIA) is an alternative sensitive cervical screening method. Therefore the aim of this study was to assess the magnitude and associated factors of VIA positive test results for Cervical Cancer screening among Eritrean refugee women aged 25-49 years in northern Ethiopia refugee camps.MethodsA community based cross-sectional study was conducted among 412 Eritrean refugee women aged 25-49 years from august 10 to September 25, 2018. Study subjects were selected by simple random sampling method. Data were collected using pretested structured questioner through Face-to-face interview and cervical examination. Data were coded and entered to Epi info software version 7 and then exported to Statistical package for Social Science (SPSS) version 21 for analysis. Bivariable and multivariable logistic regression analysis was made to test the association between the independent variables and the outcome variable. P-value of less than 0.05 with 95% CI was considered to declare statistical significance.ResultIn this study the magnitude of VIA positive precancerous cervical lesions was 9% (95% CI: 6.3-11.8%). Previous history of sexually transmitted infections (STI) [AOR (95%CI) = 2.84(1.07-7.53)] and presence of STI during cervical examination [AOR (95%CI) =3.97(1.75-9.00)] were found significantly associated with VIA positive precancerous cervical lesions.ConclusionsIn this study the magnitude of VIA positive precancerous cervical lesions was high. Previous history of sexually transmitted infections (STI) and presence of STI during cervical examination were found associated with VIA positive precancerous cervical lesions. Efforts such as early screening for sexually transmitted disease shall be done to prevent precancerous cervical lesions.

Project description:PurposeTo analyze trends in detection method related to breast cancer stage at diagnosis, treatments, and outcomes over time among 40-49-year-old women.Materials and methodsi This study was institutional review board approved, with a waiver of informed consent, and HIPAA compliant. A longitudinal prospective cohort study was conducted of women aged 40-49 years who had primary breast cancer, during 1990-2008, and were identified and tracked by a dedicated registry database (n = 1977). Method of detection--patient detected (PtD), physician detected (PhysD), or mammography detected (MamD)--was chart abstracted. Disease-specific survival and relapse-free survival statistics were calculated by using the Kaplan-Meier method for stage I-IV breast cancer.ResultsA significant increase in the percentage of MamD breast cancer over time (28%-58%) and a concurrent decline in patient and physician detected (Pt/PhysD) breast cancer (73%-42%) (Pearson x(2) = 72.72, P < .001) were observed over time from 1990 to 2008, with an overall increase in lower-stage disease detection and a decrease in higher-stage disease. MamD breast cancer patients were more likely to undergo lumpectomy (67% vs 48% of Pt/PhysD breast cancer patients) and less likely to undergo modified radical mastectomy (25% vs 47% of the Pt/PhysD breast cancer patients) (P < .001). Uncorrected for stage, 13% of MamD breast cancer patients underwent surgery and chemotherapy versus 22% of Pt/PhysD breast cancer patients (P < .001), and 31% of MamD breast cancer patients underwent surgery, radiation therapy, and chemotherapy versus 59% of Pt/PhysD breast cancer patients (x(2) = 305.13, P < .001). Analyzing invasive cancers only, 5-year relapse-free survival for MamD breast cancer patients was 92% versus 88% for Pt/PhysD patients (log-rank test, 12.47; P < .001).ConclusionIncreased mammography-detected breast cancer over time coincided with lower-stage disease detection resulting in reduced treatment and lower rates of recurrence, adding factors to consider when evaluating the benefits of mammography screening of women aged 40-49 years.

Project description:BackgroundGlobally, cervical cancer is the second most common and the leading cause of death in women in low-income countries. It is one of the potentially preventable cancers, and an effective screening program can result in a significant reduction in the morbidity and mortality associated with this cancer; however, evidence showed that only a small percentage of the women were screened. As a result, predictors of cervical cancer screening usage among women in Ambo town, central Ethiopia, were identified in this study.MethodUnmatched, a community-based case-control study was conducted among 195 randomly sampled women in the age group of 30-49 years in Ambo town from February 1 to March 30, 2020. Data was collected using an interviewer-administered questionnaire. Descriptive, bivariate, and multivariable binary logistic regression analysis was done using SPSS.ResultsA total of 195 study participants, sixty-five cases and one hundred thirty controls, participated in this study, making a response rate of 100%. Being in the age group of 30-34 years old (AOR = 0.2; 95% CI: 0.06-0.7), being Para five and above (AOR = 4.5; 95% CI: 1.4-14.1), modern contraceptive utilization (AOR = 5.4; 95% CI: 1.8-16.3) and having high-level knowledge regarding cervical cancer screening and its predisposing factors (AOR = 5.9; 95% CI: 2-17) were significantly associated with the utilization of cervical cancer screening.ConclusionThe age of women, parity, use of modern contraception, and level of knowledge regarding cervical cancer screening and its predisposing factors were the determinants of the utilization of cervical cancer screening among women. As a result, the media, the health bureau, and health professionals should advocate raising awareness about cervical cancer and its preventative methods, which are primarily focused on screening.

Project description:There was concern that failure to screen women aged 20-24 years would increase the number of cancers or advanced cancers in women aged 20-29 years. We describe the characteristics of women diagnosed with cervical cancer in England aged 20-29 years and examine the association between the period of diagnosis, screening history and FIGO stage.We used data on 1800 women diagnosed with cervical cancer between April 2007 and March 2012 at age 20-29 from the National Audit of Invasive Cervical Cancers.The majority of cancers (995, or 62% of those with known stage) were stage 1A. Cancer at age 20-24 years was rare (12% of those aged 20-29 years), when compared with age 25 (24%) and age 26-29 years (63%); however, cancers in women aged 20-24 years tended to be more advanced and were more often of a rare histological type. For 59% of women under age 30, the cervical cancer was screen detected, most of them (61%) as a result of their first screening test. A three-fold increase in the number of cancers diagnosed at age 25 years was seen since the start of the study period.Cervical cancer at age 20-24 years is rare. Most cancers in women under age 30 years are screen detected as microinvasive cancer.

Project description:Identifying risk factors for breast cancer specific to women in their 40s could inform screening decisions.To determine what factors increase risk for breast cancer in women aged 40 to 49 years and the magnitude of risk for each factor.MEDLINE (January 1996 to the second week of November 2011), Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews (fourth quarter of 2011), Scopus, reference lists of published studies, and the Breast Cancer Surveillance Consortium.English-language studies and systematic reviews of risk factors for breast cancer in women aged 40 to 49 years. Additional inclusion criteria were applied for each risk factor.Data on participants, study design, analysis, follow-up, and outcomes were abstracted. Study quality was rated by using established criteria, and only studies rated as good or fair were included. Results were summarized by using meta-analysis when sufficient studies were available or from the best evidence based on study quality, size, and applicability when meta-analysis was not possible. Data from the Breast Cancer Surveillance Consortium were analyzed with proportional hazards models by using partly conditional Cox regression. Reference groups for comparisons were set at U.S. population means.Sixty-six studies provided data for estimates. Extremely dense breasts on mammography or first-degree relatives with breast cancer were associated with at least a 2-fold increase in risk for breast cancer. Prior breast biopsy, second-degree relatives with breast cancer, or heterogeneously dense breasts were associated with a 1.5- to 2.0-fold increased risk; current use of oral contraceptives, nulliparity, and age 30 years or older at first birth were associated with a 1.0- to 1.5-fold increased risk.Studies varied by measures, reference groups, and adjustment for confounders, which could bias combined estimates. Effects of multiple risk factors were not considered.Extremely dense breasts and first-degree relatives with breast cancer were each associated with at least a 2-fold increase in risk for breast cancer in women aged 40 to 49 years. Identification of these risk factors may be useful for personalized mammography screening.National Cancer Institute.

Project description:ImportanceBreast cancer in young women has a less favorable prognosis compared with older women. Yet, comprehensive data on recent trends and how period and cohort effects may affect these trends among young women are not well-known.ObjectiveTo evaluate breast cancer incidence among young women in the US over a 20-year period by race and ethnicity, hormone receptor status (estrogen receptor [ER] and progesterone receptor [PR]), tumor stage, and age at diagnosis, as well as how period and cohort effects may affect these trends.Design, setting, and participantsThis cross-sectional study used data from Surveillance, Epidemiology, and End Results 17 registries (2000-2019). Women aged 20 to 49 years with a primary invasive breast cancer were included. Data were analyzed between February and June 2023.Main outcomes and measuresAge-standardized incidence rates (ASIR), incidence rate ratios (IRR), and average annual percent changes (AAPC) stratified by race and ethnicity, hormone receptor status, tumor stage, and age at diagnosis.ResultsOut of 217 815 eligible women (1485 American Indian or Alaska Native [0.7%], 25 210 Asian or Pacific Islander [11.6%], 27 112 non-Hispanic Black [12.4%], 37 048 Hispanic [17.0%], 126 960 non-Hispanic White [58.3%]), the majority were diagnosed with an ER+/PR+ tumor (134 024 [61.5%]) and were diagnosed with a stage I tumor (81 793 [37.6%]). Overall, invasive breast cancer incidence increased (AAPC, 0.79; 95% CI, 0.42 to 1.15), with increasing trends across almost all racial and ethnic groups. ASIR increased for ER+/PR+ (AAPC, 2.72; 95% CI, 2.34 to 3.12) and ER+/PR- tumors (AAPC, 1.43; 95% CI, 1.00 to 1.87), and decreased for ER-/PR+ (AAPC, -3.25; 95% CI, -4.41 to -2.07) and ER-/PR- tumors (AAPC, -0.55; 95% CI, -1.68 to 0.60). For women aged 20 to 29 and 30 to 39 years, ASIRs were highest among non-Hispanic Black women (age 20-29 years: IRR, 1.53; 95% CI, 1.43 to 1.65; age 30-39 years: IRR, 1.15; 95% CI, 1.12 to 1.18). For women aged 40 to 49 years, ASIR was lower for non-Hispanic Black women (IRR, 0.96; 95% CI, 0.94 to 0.97) compared with non-Hispanic White women. Incidence rates increased for stages I and IV tumors but decreased for stage II and III tumors. Age-period-cohort analysis demonstrated both cohort and period effects on breast cancer incidence (P < .001).Conclusions and relevanceIn this population-based cross-sectional analysis, an increase in breast cancer incidence rates among young US women and age-related crossover between non-Hispanic White and Black women were observed. Prevention efforts in young women need to adopt a targeted approach to address racial disparities in incidence rates observed at different age phases.
