ABSTRACT

Background: In Burkina Faso, access to health services for women, children and people living with HIV/AIDS (PLWHAs) remains limited. Mobile telephony offers an alternative solution for reaching these individuals. The objective of the study was to improve equity of access to health care and information among women and PLWHAs by reinforcing community participation. Methods: Using a quasi-experimental approach, a mobile telephone system was set up at five health centres to provide an automated reminder service for health care consultation appointments. Performance evaluations based on key performance indicators were subsequently conducted. Results: A total of 1501 pregnant women and 301 PLWHAs were registered and received appointment reminders. A 7.34% increase in prenatal coverage, an 84% decrease in loss to follow-up for HIV (P < 0.001) and a 31% increase in assisted deliveries in 2016 (P < 0.0001) were observed in intervention areas. However, there was no statistically significant difference between intervention site and control site (P= 0.451 > 0.05) at post-intervention. Efforts to involve community members in decision-making processes contributed to improved health system governance. Conclusion: Mhealth may improve maternal and child health and the health of PLWHAs. However, establishment of a mHealth system requires taking into account community dynamics and potential technological challenges. Keywords: access to care, Burkina Faso, equity, health system governance, mobile telephony, Nouna.

ABSTRACT

AIM: Most people who are at increased familial colorectal cancer (FCRC) risk are not identified, despite the need for enhanced surveillance colonoscopy for effective CRC prevention. An online self-test may enhance this identification. We assessed whether taking an online self-test to identify increased FCRC risk increases anxiety, distress or CRC risk perception in population-based CRC screening. METHOD: After the precolonoscopy consultation, patients who had a positive immunohistochemical occult faecal blood test (iFOBT+) in population-based CRC screening were invited by email to take an online self-test at home which returned details of family history. Anxiety (STAI-DY), distress (HADS) and CRC risk perception were assessed immediately before and after taking the online self-test and 2 weeks later. RESULTS: Of 250 participants invited, 177 (71%) completed the online self-test and psychological questionnaires and 153 (61%) completed questionnaires 2 weeks later. The median age was 65 years (range 61-75). The FCRC risk was increased in 17 participants (9.6%). Of these, 12 (6.8%) had a highly increased FCRC risk and may benefit from germline genetic testing for Lynch syndrome. In 7 of 17 participants (40%) the self-test obtained novel information on family history. Anxiety and distress levels were, and remained, below a clinically relevant level. Perception of CRC risk remained unchanged. Most participants (83%) would recommend the online self-test to others. CONCLUSION: Of those with a iFOBT+, 9.6% had a previously unidentified increasedFCRC risk and require an enhanced surveillance colonoscopy instead of iFOBT. As screening for this risk did not increase anxiety or distress, and was highly acceptable, we recommend adding the online self-test to population-based CRC screening.

ABSTRACT

BACKGROUND: Vaccination has contributed to major reductions in global morbidity and mortality, but there remain significant coverage gaps. Better knowledge on the interplay between population and health systems regarding provision of vaccination information and regarding health staff organization during the immunization sessions appears to be important for improvements of vaccination effectiveness. METHODS: The study was conducted in the Nouna Health and Demographic Surveillance System (HDSS) area, rural Burkina Faso, from March to April 2014. We employed a combination of in-depth interviews (n = 29) and focus group discussions (n = 4) including children's mothers, health workers, godmothers, community health workers and traditional healers. A thematic analysis was performed. All material was transcribed, translated and analyzed using the software ATLAS.ti4.2. RESULTS: There was better social mobilization in the rural areas as compared to the urban area. Most mothers know the Expanded Program of Immunization (EPI) target diseases, and the importance to immunize their children. However, the great majority of informants reported that mothers don't know the vaccination schedule. There is awareness that some children are incompletely vaccinated. Mentioned reasons for that were migration, mothers being busy with their work, the practice of not opening vaccine vials unless a critical number of children are present, poor interaction between women and health workers during immunization sessions, potential adverse events associated with vaccination, geographic inaccessibility during rainy season, and lack of information. CONCLUSIONS: Well organized vaccination programs are a key factor to improve child health and there is a clear need to consider community perceptions on program performance. In Burkina Faso, a number of factors have been identified which need attention by the EPI managers for further improvement of program effectiveness.

ABSTRACT

INTRODUCTION: Previous studies in African countries have been suggestive of non-specific effects (NSE) of vaccination on child survival. Live vaccines (e.g. measles, MV) have been found to reduce child mortality while inactivated vaccines (e.g. diphtheria-tetanus-pertussis, DTP) have been associated with increased mortality; NSE were often found to be sex-specific. METHODS: A case-control study nested into the Health and Demographic Surveillance System (HDSS) cohort of the Centre de Recherche en Santé de Nouna (CRSN) was conducted in northwestern Burkina Faso. A total of 3,010 children born in 2009-11, were included in the study, 375 cases and 2635 age and village matched controls. The main outcome measures were the mortality odds ratios for vaccinated versus unvaccinated children by antigen. The main outcome measures were the mortality odds ratios for vaccinated versus unvaccinated children by antigen. RESULTS: Most deaths occurred in late infancy, and there were significantly more deaths in males as compared to females (OR 1.29, CI 1.04-1.60). Overall, there was no statistically significant association between vaccine status and mortality. However, among children in the age group 2-8 months, there was a consistent sex-differential pattern for all doses of oral polio vaccine combined with pentavalent vaccine (OPV + Penta), with the vaccines being associated with lower mortality in boys, but not in girls. Routine MV + yellow fever vaccine was associated with reduced mortality, but only before mass vaccination campaigns with meningitis and measles vaccines took place. CONCLUSIONS: The findings of this study provide further support on the existence of NSE of childhood vaccinations in a large population of rural Burkina Faso. More randomized controlled trials are needed to confirm these observations.

ABSTRACT

INTRODUCTION: Identifying high familial breast cancer (FBC) risk improves detection of yet unknown BRCA1/2-mutation carriers, for whom BC risk is both highly likely and potentially preventable. We assessed whether a new online self-test could identify women at high FBC risk in population-based BC screening without inducing anxiety or distress. METHODS: After their visit for screening mammography, women were invited by email to take an online self-test for identifying highly increased FBC risk-based on Dutch guidelines. Exclusion criteria were previously diagnosed as increased FBC risk or a personal history of BC. Anxiety (State-Trait Anxiety Inventory Dutch Version), distress (Hospital Anxiety Depression Scale) and BC risk perception were assessed using questionnaires, which were completed immediately before and after taking the online self-test and 2 weeks later. RESULTS: Of the 562 women invited by email, 406 (72%) completed the online self-test while 304 also completed questionnaires (response rate 54%). After exclusion criteria, 287 (51%) were included for data analysis. Median age was 56 years (range 50-74). A high or moderate FBC risk was identified in 12 (4%) and three (1%) women, respectively. After completion of the online self-test, anxiety and BC risk perception were decreased while distress scores remained unchanged. Levels were below clinical relevance. Most women (85%) would recommend the self-test; few (3%) would not. CONCLUSION: The online self-test identified previously unknown women at high FBC risk (4%), who may carry a BRCA1/2-mutation, without inducing anxiety or distress. We therefore recommend offering this self-test to women who attend population-based screening mammography for the first time.

ABSTRACT

BRCA1/2-mutation carriers are at high risk of breast cancer (BC) and ovarian cancer. Physical inactivity, overweight (body mass index ≥25, BMI), smoking, and alcohol consumption are jointly responsible for about 1 in 4 postmenopausal BC cases in the general population. Limited evidence suggests physical activity also increases BC risk in BRCA1/2-mutation carriers. Women who have children often reduce physical activity and have weight gain, which increases BC risk. We assessed aforementioned lifestyle factors in a cohort of 268 BRCA1/2-mutation carriers around childbearing age (born between 1968 and 1983, median age 33 years, range 21-44). Furthermore, we evaluated the effect of having children on physical inactivity and overweight. Carriers were asked about lifestyle 4-6 weeks after genetic diagnosis at the Familial Cancer Clinic Nijmegen. Physical inactivity was defined as sports activity fewer than once a week. Carriers were categorized according to the age of their youngest child (no children, age 0-3 years and ≥4 years). In total, 48% of carriers were physically inactive, 41% were overweight, 27% smoked, and 70% consumed alcohol (3% ≥8 beverages/week). Physical inactivity was 4-5 times more likely in carriers with children. Overweight was not associated with having children. Carriers with children are a subgroup that may specifically benefit from lifestyle support to reduce BC risk.

ABSTRACT

The Radboud University Medical Center was among the first to implement two-step exome sequencing in clinical genetic diagnostics. This study is the first to evaluate patient experiences with gene panels based on exome sequencing, using quantified psychological variables: acceptance, psychological distress, expectations of heredity and unsolicited findings. Between August 2011 and July 2012, 177 patients diagnosed with early-onset colorectal/kidney cancer, deafness, blindness or movement disorder consented to diagnostic exome sequencing offered by clinical geneticists. Baseline questionnaires were sent to 141 adults, returned by 111 with median age of 49 [22-79] years and positive family history in 81%. Follow-up included 91 responders at median 4 [2-22] weeks after results from known gene panels per diagnosis group; exome-wide analysis is ongoing. Confirmed or possibly pathogenic mutations were found in 31% with one unsolicited finding (oncogenetic panel). Most patients (92%) were satisfied. There were no significant changes in heredity-specific distress (18% at baseline, 17% at follow-up) and expectations of heredity. Fewer patients expected unsolicited findings at follow-up (29% vs 18%, p = 0.01). Satisfaction and distress were equal in those with vs without mutations. In conclusion, most adults accepted and were satisfied with gene panels based on diagnostic exome sequencing, few reporting distress.

ABSTRACT

INTRODUCTION: Performance-based incentives (PBIs) are currently receiving attention as a strategy for improving the quality of care that health providers deliver. Experiences from several African countries have shown that PBIs can trigger improvements, particularly in the area of maternal and neonatal health. The involvement of health workers in deciding how their performance should be measured is recommended. Only limited information is available about how such schemes can be made sustainable. This study explored the types of PBIs that rural health workers suggested, their ideas regarding the management and sustainability of such schemes, and their views on which indicators best lend themselves to the monitoring of performance. In this article the authors reported the findings from a cross-country survey conducted in Burkina Faso, Ghana and Tanzania. METHODS: The study was exploratory with qualitative methodology. In-depth interviews were conducted with 29 maternal and neonatal healthcare providers, four district health managers and two policy makers (total 35 respondents) from one district in each of the three countries. The respondents were purposively selected from six peripheral health facilities. Care was taken to include providers who had a management role. By also including respondents from district and policy level a comparison of perspectives from different levels of the health system was facilitated. The data that was collected was coded and analysed with support of NVivo v8 software. RESULTS: The most frequently suggested PBIs amongst the respondents in Burkina Faso were training with per-diems, bonuses and recognition of work done. The respondents in Tanzania favoured training with per-diems, as well as payment of overtime, and timely promotion. The respondents in Ghana also called for training, including paid study leave, payment of overtime and recognition schemes for health workers or facilities. Respondents in the three countries supported the mobilisation of local resources to make incentive schemes more sustainable. There was a general view that it was easier to integrate the cost of non-financial incentives in local budgets. There were concerns about the fairness of such schemes from the provider level in all three countries. District managers were worried about the workload that would be required to manage the schemes. The providers themselves were less clear about which indicators best lent themselves to the purpose of performance monitoring. District managers and policy makers most commonly suggested indicators that were in line with national maternal and neonatal healthcare indicators. CONCLUSIONS: The study showed that health workers have considerable interest in performance-based incentive schemes and are concerned about their sustainability. There is a need to further explore the use of non-financial incentives in PBI schemes, as such incentives were considered to stand a greater chance of being integrated into local budgets. Ensuring participation of healthcare providers in the design of such schemes is likely to achieve buy-in and endorsement from the health workers involved. However, input from managers and policy makers is essential to keep expectations realistic and to ensure the indicators selected fit the purpose and are part of routine reporting systems.

ABSTRACT

BACKGROUND: Recognising colorectal cancer (CRC) patients with Lynch syndrome (LS) can increase life expectancy of these patients and their close relatives. To improve identification of this under-diagnosed disease, experts suggested raising the age limit for CRC tumour genetic testing from 50 to 70 years. The present study evaluates the efficacy and cost-effectiveness of this strategy. METHODS: Probabilistic efficacy and cost-effectiveness analyses were carried out comparing tumour genetic testing of CRC diagnosed at age 70 or below (experimental strategy) versus CRC diagnosed at age 50 or below (current practice). The proportions of LS patients identified and cost-effectiveness including cascade screening of relatives, were calculated by decision analytic models based on real-life data. RESULTS: Using the experimental strategy, four times more LS patients can be identified among CRC patients when compared with current practice. Both the costs to detect one LS patient (€9437/carrier versus €4837/carrier), and the number needed to test for detecting one LS patient (42 versus 19) doubled. When family cascade screening was included, the experimental strategy was found to be highly cost-effective according to Dutch standards, resulting in an overall ratio of €2703 per extra life-year gained in additionally tested patients. CONCLUSION: Testing all CRC tumours diagnosed at or below age 70 for LS is cost-effective. Implementation is important as relatives from the large number of LS patients that are missed by current practice, can benefit from life-saving surveillance.

ABSTRACT

In Burkina Faso where cooking with biomass is very common, little information exists regarding kitchen characteristics and their impact on air pollutant levels. The measurement of air pollutants such as respirable particulate matter (PM10), an important component of biomass smoke that has been linked to adverse health outcomes, can also pose challenges in terms of cost and the type of equipment needed. Carbon monoxide could potentially be a more economical and simpler measure of air pollution. The focus of this study was to first assess the association of kitchen characteristics with measured PM10 and CO levels and second, the relationship of PM10 with CO concentrations, across these different kitchen characteristics in households in Nouna, Burkina Faso. Twenty-four-hour concentrations of PM10 (area) were measured with portable monitors and CO (area and personal) estimated using color dosimeter tubes. Data on kitchen characteristics were collected through surveys. Most households used both wood and charcoal burned in three-stone and charcoal stoves. Mean outdoor kitchen PM10 levels were relatively high (774 µg/m(3), 95 % CI 329-1,218 µg/m(3)), but lower than indoor concentrations (Satterthwaite t value, -6.14; p < 0.0001). In multivariable analyses, outdoor kitchens were negatively associated with PM10 (OR = 0.06, 95 % CI 0.02-0.16, p value <0.0001) and CO (OR = 0.03, 95 % CI 0.01-0.11, p value <0.0001) concentrations. Strong area PM10 and area CO correlations were found with indoor kitchens (Spearman's r = 0.82, p < 0.0001), indoor stove use (Spearman's r = 0.82, p < 0.0001), and the presence of a smoker in the household (Spearman's r = 0.83, p < 0.0001). Weak correlations between area PM10 and personal CO levels were observed with three-stone (Spearman's r = 0.23, p = 0.008) and improved stoves (Spearman's r = 0.34, p = 0.003). This indicates that the extensive use of biomass fuels and multiple stove types for cooking still produce relatively high levels of exposure, even outdoors, suggesting that both fuel subsidies and stove improvement programs are likely necessary to address this problem. These findings also indicate that area CO color dosimeter tubes could be a useful measure of area PM10 concentrations when levels are influenced by strong emission sources or when used in indoors. The weaker correlation observed between area PM10 and personal CO levels suggests that area exposures are not as useful as proxies for personal exposures, which can vary widely from those recorded by stationary monitors.

ABSTRACT

OBJECTIVE: To identify the determinants of timely vaccination among young children in the North-West of Burkina Faso. METHODS: This study included 1665 children between 12 and 23 months of age from the Nouna Health and Demographic Surveillance System, born between September 2006 and December 2008. The effect of socio-demographic variables on timely adherence to the complete vaccination schedule was studied in multivariable ordinal logistic regression with 3 distinct endpoints: (i) complete timely adherence, (ii) failure, and (iii) missing vaccination. Three secondary endpoints were timely vaccination with BCG, Penta3, and measles, which were studied with standard multivariable logistic regression. RESULTS: Mothers' education, socio-economic status, season of birth, and area of residence were significantly associated with failure of timely adherence to the complete vaccination schedule. Year of birth, ethnicity, and the number of siblings was significantly related to timely vaccination with Penta3 but not with BCG or measles vaccination. Children living in rural areas were more likely to fail timely vaccination with BCG than urban children (OR=1.79, 95%CI=1.24-2.58 (proximity to health facility), OR=3.02, 95%CI=2.18-4.19 (long distance to health facility)). In contrast, when looking at Penta3 and measles vaccination, children living in rural areas were far less likely to have failed timely vaccinations than urban children. Mother's education positively influenced timely adherence to the vaccination schedule (OR=1.42, 95%CI 1.06-1.89). There was no effect of household size or the age of the mother. CONCLUSIONS: Additional health facilities and encouragement of women to give birth in these facilities could improve timely vaccination with BCG. Rural children had an advantage over the urban children in timely vaccination, which is probably attributable to outreach vaccination teams amongst other factors. As urban children rely on their mothers' own initiative to get vaccinated, urban mothers should be encouraged more strongly to get their children vaccinated in time.

ABSTRACT

OBJECTIVES: To measure pre-intervention quality of routine antenatal and childbirth care in rural districts of Burkina Faso, Ghana and Tanzania and to identify shortcomings. METHODS: In each country, we selected two adjoining rural districts. Within each district, we randomly sampled 6 primary healthcare facilities. Quality of care was assessed through health facility surveys, direct observation of antenatal and childbirth care, exit interviews and review of patient records. RESULTS: By and large, quality of antenatal and childbirth care in the six districts was satisfactory, but we did identify some critical gaps common to the study sites in all three countries. Counselling and health education practices are poor; laboratory investigations are often not performed; examination and monitoring of mother and newborn during childbirth are inadequate; partographs are not used. Equipment required to provide assisted vaginal deliveries (vacuum extractor or forceps) was absent in all surveyed facilities. CONCLUSION: Quality of care in the three study sites can be improved with the available human resources and without major investments. This improvement could reduce maternal and neonatal mortality and morbidity.

ABSTRACT

As the last part of a program to survey the extent of malaria transmission in the Papua New Guinea highlands, a series of rapid malaria surveys were conducted in 2003-2004 and 2005 in different parts of Southern Highlands Province. Malaria was found to be highly endemic in Lake Kutubu (prevalence rate (PR): 17-33%), moderate to highly endemic in Erave (PR: 10-31%) and moderately endemic in low-lying parts (< 1500 m) of Poroma and Kagua (PR: 12-17%), but was rare or absent elsewhere. A reported malaria epidemic prior to the 2004 surveys could be confirmed for the Poroma (PR: 26%) but not for the lower Kagua area. In Kutubu/Erave Plasmodium falciparum was the most common cause of infection (42%), followed by P. vivax (39%) and P. malariae (16%). In other areas most infections were due to P. vivax (63%). Most infections were of low density (72% < 500/ microl) and not associated with febrile illness. Overall, malaria was only a significant source of febrile illness when prevalence rates rose above 10%, or in epidemics. However, concurrent parasitaemia led to a significant reduction in haemoglobin (Hb) level (1.2 g/dl, CI95: [1.1-1.4.], p < 0.001) and population mean Hb levels were strongly correlated with overall prevalence of malarial infections (r = -0.79, p < 0.001). Based on the survey results, areas of different malaria epidemiology are delineated and options for control in each area are discussed.

ABSTRACT

Knowledge and practices with respect to malaria are aspects that need to be considered as part of effective malaria programs. We assessed and compared malaria practices and knowledge among those who had recently visited a health care provider and those who had not. A matched, population-based case-control study was conducted among 338 women between 15 and 45 years of age and caretakers of children ≤ 9 years of age in Nouna, Burkina Faso. Little difference was found in the reported responses between the cases and controls, which indicates that recent visits to health care providers may not have an effect on malaria risk or knowledge. Differences were noted in malaria practices, which could suggest that health care providers are consulted only after home treatments fail. Therefore, programs and policies targeted to health care providers aimed at improving the dissemination of information may be of some benefit.

ABSTRACT

Access to health-care is low in developing countries. Poor people are less likely to seek care than those who are better off. Community-based health insurance (CBI) aims to improve healthcare utilisation by removing financial barriers, unfortunately CBI has been less effective in securing equity than expected. Poor people, who probably require greater protection from catastrophic health expenses, are less likely to enrol in such schemes. Therefore, it is important to implement targeted interventions so that the most in need are not left out. CBI has been offered to a district in Burkina Faso, comprising 7762 households in 41 villages and the district capital of Nouna since 2004. Community wealth ranking (CWR) was used in 2007 to identify the poorest quintile of households who were subsequently offered insurance at half the usual premium rate. The CWR is easy to implement and requires minimal resources such as interviews with local informants. As used in this study, the agreement between the key informants was more (37.5%) in the villages than in Nouna town (27.3%). CBI management unit only received nine complaints from villagers who considered that some households had been wrongly identified. Among the poorest, the annual enrolment increased from 18 households (1.1%) in 2006 to 186 (11.1%) in 2007 after subsidies. CWR is an alternative methodology to identify poor households and was found to be more cost and time efficient compared to other methods. It could be successfully replicated in low-income countries with similar contexts. Moreover, targeted subsidies had a positive impact on enrolment.

The risk of malaria can be influenced by the household environment. The range of these risks can be more diverse in semi-urban areas, which can include a mix of different housing styles and environments. This study examined the effect of different housing and household characteristics on malaria risk among 98 case and 185 control children in the semi-urban area of Nouna, Burkina Faso. Characteristics were assessed via questionnaires and direct inspection. Those characteristics associated with a decreased risk of malaria were floors constructed of earth bricks and running water in the neighbourhood. Electrification of the home and house age of <10 years were associated with an increased risk of malaria. The findings of this study suggest that modification of the household environment could be a feasible way to reduce the risk of malaria, particularly in semi-urban areas.

ABSTRACT

We analysed cerebrospinal fluid samples from suspected meningitis cases in Nouna Health District, Burkina Faso, during the meningitis seasons of 2004-2006. Serogroup A ST2859 meningococci belonging to the ST5 clonal complex of subgroup III meningococci were the predominant causative agent. ST2859 bacteria were associated with focal outbreaks in the north of the district. While >10% of the population of an outbreak village carried ST2859, the population in the south of the district was predominantly colonised by serogroup Y ST4375 meningococci, which were associated with only sporadic cases of meningitis. Colonisation with the less virulent Y meningococci may interfere with the spread of the ST2859 to the south of the district, but there are concerns that this serogroup A clone may cause a third wave of subgroup III meningococcal disease in the African Meningitis Belt.

ABSTRACT

OBJECTIVE: To assess the quality of healthcare workers' performance with regard to malaria diagnosis and treatment and to assess patients' self-medication with chloroquine (CQ) before and after presentation at a health centre. METHODS: In the rainy season 2004, in five rural dispensaries in Burkina Faso, we observed 1101 general outpatient consultations and re-examined all these patients. CQ whole blood concentrations of confirmed malaria cases were measured before and after treatment. RESULTS: The clinical diagnosis based on fever and/or a history of fever had a sensitivity of 75% and a specificity of 41% when compared to confirmed malaria (defined as an axillary temperature of >/=37.5 degrees C and/or a history of fever and parasites of any density in the blood smear). Few febrile children under 5 years of age were assessed for other diseases than malaria such as pneumonia. No antimalarial was prescribed for 1.3% of patients with the clinical diagnosis malaria and for 24% of confirmed cases, while 2% received an antimalarial drug prescription without the corresponding clinical diagnosis. CQ was overdosed in 22% of the prescriptions. Before and 2 weeks after consultation, 25% and 46% respectively of the patients with confirmed malaria had potentially toxic CQ concentrations. CONCLUSION: As long as artemisinin-based combination therapy remains unavailable or unaffordable for most people in rural areas of Burkina Faso, self-medication with and prescription of CQ are likely to continue despite increasing resistance. Apart from considering more pragmatic first-line regimens for malaria treatment such as the combination of sulfadoxine-pyrimethamine with amodiaquine, more and better training on careful clinical management of febrile children including an appropriate consideration of other illnesses than malaria should be made available in the frame of the IMCI initiative in sub-Saharan Africa.

ABSTRACT

PURPOSE: To investigate the general applicability and interobserver variability of ultrasonographic (US) features in differentiating benign from malignant solid breast masses. MATERIALS AND METHODS: One hundred sixty-two consecutive solid masses with a tissue diagnosis were reviewed. Three radiologists reviewed the masses without knowledge of clinical history or histologic examination results. RESULTS: US features that most reliably characterize masses as benign were a round or oval shape (67 of 71 [94%] were benign), circumscribed margins (95 of 104 [91%] were benign), and a width-to-anteroposterior (AP) dimension ratio greater than 1.4 (82 of 92 [89%] were benign). Features that characterize masses as malignant included irregular shape (19 of 31 [61%] were malignant), microlobulated (four of six [67%] were malignant) or spiculated (two of three [67%] were malignant) margins, and width-to-AP dimension ratio of 1.4 or less (28 of 70 [40%] were malignant). If the three most reliable criteria had been strictly applied by each radiologist, the overall cancer biopsy yield would have increased (from 23% to 39%) by 16%. When US images and mammograms were available, the increase in biopsy yield contributed by US was not statistically significant (2%, P = .73). However, in independent reviews, one to three reviewers interpreted four carcinomas as benign at US. CONCLUSION: The data confirm that certain US features can help differentiate benign from malignant masses. However, practice and interpreter variability should be further explored before these criteria are generally applied to defer biopsy of solid masses.

ABSTRACT

BACKGROUND: In longitudinal studies, greater mammographic density is associated with an increased risk for breast cancer. OBJECTIVE: To assess differences between placebo, estrogen, and three estrogen-progestin regimens on change in mammographic density. DESIGN: Subset analysis of a 3-year, multicenter, double-blind, randomized, placebo-controlled trial. SETTING: Seven ambulatory study centers. PARTICIPANTS: 307 of the 875 women in the Postmenopausal Estrogen/Progestin Interventions Trial. Participants had a baseline mammogram and at least one follow-up mammogram available, adhered to treatment, had not taken estrogen for at least 5 years before baseline, and did not have breast implants. INTERVENTION: Treatments were placebo, conjugated equine estrogens (CEE), CEE plus cyclic medroxyprogesterone acetate (MPA), CEE plus daily MPA, and CEE plus cyclic micronized progesterone (MP). MEASUREMENTS: Change in radiographic density (according to American College of Radiology Breast Imaging Reporting and Data System grades) on mammography. RESULTS: Almost all increases in mammographic density occurred within the first year. At 12 months, the percentage of women with density grade increases was 0% (95% CI, 0.0% to 4.6%) in the placebo group, 3.5% (CI, 1.0% to 12.0%) in the CEE group, 23.5% (CI, 11.9% to 35.1%) in the CEE plus cyclic MPA group, 19.4% (CI, 9.9% to 28.9%) in the CEE plus daily MPA group, and 16.4% (CI, 6.6% to 26.2%) in the CEE plus cyclic MP group. At 12 months, the odds of an increase in mammographic density were 13.1 (95% CI, 2.4 to 73.3) with CEE plus cyclic MPA, 9.0 (CI, 1.6 to 50.1) with CEE plus daily MPA, and 7.2 (CI, 1.3 to 40.0) with CEE plus cyclic micronized progesterone compared with CEE alone. CONCLUSIONS: Further study of the magnitude and meaning of increased mammographic density due to use of estrogen and estrogen-progestins is warranted because mammographic density may be a marker for risk for breast cancer.
