Knowledge and practice of breast self-examination among breast cancer patients in Damascus, Syria

BACKGROUND

Breast cancer (BC) represents an important cause of cancer death, its incidence rate has been rising gradually in the Arab world, and in Syria, BC is the most common cancer and the leading cause of cancer death; its prognosis gets better as we detect it early in its first stages. So, it is very important to implement one or more early detection methods such as Breast Self-Examination (BSE), Clinical Breast Examination (CBE), and mammography. BSE represents an effective method to find out changes in breast structure when they happen. This study investigates the knowledge of BSE and its practice in BC patients.

METHODS

A quantitative cross-sectional study in Al-Bairouni hospital in Damascus-Syria was carried out using face-to-face interviews based on a structured questionnaire, which consisted of 4 sections. The data were subjected to statistical analysis using various analytical tests, including the independent t-test, one-way analysis of variance (ANOVA), and Chi-square test.

RESULTS

Five hundred patients were interviewed. Only 27.4% of patients had a good knowledge of BSE, 17.4% had average knowledge, and 55.2% had low knowledge of BSE. The factors that have an impact on the knowledge of BSE were: family breast cancer history (first and second-degree relatives), education, and the region of living (between governorates). The effect of knowledge of BSE on its practice was positive. However, only 24.8% of patients have been practicing BSE; the reasons for not practicing BSE were: no one has told the patient about it (64.8% of cases), and the patient does not have any symptoms relating to the breast (21.4%).Breast cancer was identified through breast self-examination (BSE) in 15.6% of cases.

CONCLUSION

There is a low degree of knowledge and little practice of BSE among Syrian breast cancer patients. Family breast cancer history, governate, occupation, and level of education had a statistically significant effect on knowledge scores of BSE, unlike age and social status. So, some steps should be taken to increase awareness about BSE among Syrian females.

Intention to Undergo Clinical Breast Examination and Its Associated Factors among Women Attending Rural Primary Healthcare Facilities in South Central Ethiopia

Background

Breast cancer is a global public health problem with higher mortality in developing countries. The Ethiopian National Cancer Control Plan recommends clinical breast examination (CBE) for all women aged >18 years. However, there is low breast examination practice in Ethiopia. Therefore, this study aimed to describe level of intention to undergo CBE and associated factors among women visited selected rural healthcare facilities in south central Ethiopia using Theory of Planned Behavior (TPB).

Methods

This study used facility-based cross-sectional study design. A total of 420 women participated in this study. Interviewer-administered structured questionnaire was adopted from previously published research works and Ajzen's TPB manual. Statistical Package for Social Sciences (SPSS), version 27, was used for analysis. Binary logistic regression model was used to determine factors associated with intention to undergo CBE.

Results

In this study, nine out of ten women had never had CBE. Mean score for intention to undergo CBE was 12.55 (SD ± 3.22; min 5, max 20). Intention to undergo CBE was negatively associated with being in the second and middle wealth quantiles compared to the highest wealth quantile, and with the spouse not being able to read or write compared to having attended formal education. Positive attitude and higher subjective norm had relevant association with intention to undergo CBE.

Conclusion

The high score for intention to undergo CBE should encourage primary healthcare facilities to offer CBE. Behavioral change communication interventions could address women's attitude, subjective norm, and spouse's education associated with intention to undergo CBE.

Factors associated with the uptake of clinical breast examination among women of reproductive age in Lesotho: analysis of a national survey

BACKGROUND

In low-resource settings with weak health systems, the WHO recommends clinical breast examination (CBE) as the most cost-effective breast screening modality for women. Evidence shows that biennial CBE leads to significant downstaging of breast cancer in all women. Breast cancer is the second most common cancer among women in Lesotho with a weaker healthcare system and a low breast cancer screening rate. This study investigated the prevalence and factors associated with the uptake of CBE among women of reproductive age in Lesotho.

METHODS

This study used cross-sectional data from the 2014 Lesotho Demographic and Health Survey. A sample of 6584 reproductive-age women was included in this study. We conducted both descriptive and multivariable logistic regression analyses. The study results were presented in frequencies, percentages, and adjusted odds ratios (aOR) with their corresponding confidence intervals (CIs).

RESULTS

The prevalence of CBE uptake was 9.73% (95% CI: 8.91, 10.61). Women who were covered by health insurance (aOR = 2.31, 95% CI [1.37, 3.88]), those who were pregnant (aOR = 2.34, 95% CI [1.64, 3.35]), those who had one to three children (aOR = 1.81, 95% CI [1.29,2.52]), and women who frequently read newspapers or magazines (aOR = 1.33, 95% CI [1.02,1.72]) were more likely to undergo CBE than their counterparts. Women who were aware of breast cancer (aOR = 2.54, 95% CI [1.63,3.97]), those who have ever had breast self-examination (BSE) within the last 12 months prior to the study (aOR = 5.30, 95% CI [4.35,6.46]), and those who visited the health facility in the last 12 months prior to the study (aOR = 1.57, 95% CI [1.27,1.95]) were also more likely to undergo CBE than their counterparts. Women residing in the Qacha's-nek region (aOR = 0.42, 95% CI [0.26,0.67]) were less likely to undergo CBE than those in the Botha-bothe region.

CONCLUSION

The study found a low prevalence of CBE uptake among reproductive-age women in Lesotho. Factors associated with CBE uptake include health insurance coverage, being pregnant, those who had one to three children, exposure to media, breast cancer awareness, ever had BSE, and those who visited a health facility. To increase CBE uptake, these factors should be considered when designing cancer screening interventions and policies in order to help reduce the burden of breast cancer in Lesotho.

Cost-effectiveness of clinical breast examination screening programme among HER2-positive breast cancer patients: a modelling study

PURPOSE

For many low- and middle-income countries (LMICs), breast cancer (BC) screening based on mammography is not a viable option. Clinical breast examination (CBE) may represent a pragmatic and cost-effective alternative. This paper examines the cost-effectiveness of CBE screening programme among a patient group for whom its cost-effectiveness is likely to be least evident (HER2-positive patients) and discuss the wider implications for BC screening in LMICs.

METHODS

A Markov model was used to examine clinical and economic outcomes over a life-time horizon from the patient, public payer, and healthcare sector perspective. HER2-positive patients entered the model at either disease-free survival or metastatic BC state. The downstaging effect of CBE determined the starting probabilities in the no-screening and screening scenarios. The model used a monthly cycle length, with half-cycle correction. Costs and outcomes were discounted at 1.5% annually.

RESULTS

Compared with no-screening, the cost-effectiveness ratio (ICER) per quality-adjusted life-year gained for the CBE screening programme was $1801, $2381, and $4179 from three mentioned perspectives, respectively. The finding of cost-effectiveness remained robust to a range of sensitivity analyses. The parameters to which ICERs are most sensitive are average age of cohorts, reduction in proportion of metastatic patients at diagnosis, cost of CBE, and BC detection rate of the programme.

CONCLUSION

For HER2-positive patients and compared with no-screening, CBE screening programme in Vietnam is cost-effective from all investigated perspectives. CBE is a 'good value' intervention and should be considered for implementation throughout Vietnam as well as in LMICs where mammography is not feasible.

The effect of motivational interviewing on the change of breast cancer screening behaviors among rural Iranian women

OBJECTIVE

The study aimed to determine the effect of motivational interviewing on the change of breast cancer screening behaviors among rural Iranian women.

METHODS

This Randomized controlled trial (RCT) was performed on 120 Iranian rural women selected through cluster random sampling method. Out of all 20 rural health centers of Abish Ahmad District, in the northwest of Iran, about one third (six clusters) were randomly selected; out of which three were randomly assigned to the control group and three to the intervention group. A list of women aged 40-69 years in the selective health centers was prepared and 60 participants were selected for each group through the convenience sampling method based on the inclusion and exclusion criteria. Then, six group sessions (two educational and four motivational interviewing sessions) were held for the intervention group. The data were collected using demographic and obstetric questionnaire, paper-based health records, and the stages of change checklist and analyzed in SPSS 24. The groups were compared through the chi square test, homogeneity test, and the sequential logistic regression with generalized estimating equations.

RESULTS

Two months after the intervention, a significant difference was found between the two groups in terms of the stages of change for clinical breast examination and mammography by taking into account the pre-intervention stages (p = 0.001).

CONCLUSION

MI-based counseling increased the Iranian rural women's motivation for displaying breast cancer screening behaviors.

PRACTICE IMPLICATIONS

The application of MI for enhancing cancer screening programs among Iranian women is suggested.

Impact of specificity on cost-effectiveness of screening women at high risk of breast cancer with magnetic resonance imaging, mammography and ultrasound

PURPOSE

Aim of this study was to analyze the comparative cost-effectiveness of MR-mammography vs conventional imaging in a screening setting for women with high risk of breast cancer, with particular focus on the impact of specificity of MRM.

METHOD

Decision analytic modelling and Markov Modelling were applied to evaluate cumulative costs of each screening modality and their subsequent treatments as well as cumulative outcomes in quality adjusted life years (QALYs). For the selected time horizon of 30 years, false positive and false negative results were included. Model input parameters for women with high risk of breast cancer were estimated based on published data from a US healthcare system perspective. Major influence factors were identified and evaluated in a deterministic sensitivity analysis. Based on current recommendations for economic evaluations, a probabilistic sensitivity analysis was conducted to test the model stability.

RESULTS

In a base-case analysis, screening with XM vs. MRM and treatment resulted in overall costs of $36,201.57 vs. $39,050.97 and a cumulative effectiveness of 19.53 QALYs vs. 19.59 QALYs. This led to an incremental cost-effectiveness ratio (ICER) of $ 45,373.94 per QALY for MRM. US and XM + US resulted in ICER values higher than the willingness to pay (WTP). In the sensitivity analyses, MRM remained a cost-effective strategy for screening high-risk patients as long as the specificity of MRM did not drop below 86.7 %.

CONCLUSION

In high-risk breast cancer patients, MRM can be regarded as a cost-effective alternative to XM in a yearly screening setting. Specificity may be an important cost driver in settings with yearly screening intervals.

Required examinations and tests before initiating contraception: Provider practices from a national cross-sectional survey

OBJECTIVE(S)

We estimated the prevalence of requiring specific examinations or tests before providing contraception in a nationwide survey of family planning providers.

STUDY DESIGN

We conducted a cross-sectional survey of public-sector health centers and office-based physicians providing family planning services across the United States in 2019 (n = 1395). We estimated the weighted proportion of providers (or their health center or practice) who required blood pressure measurement, pelvic examination (bimanual examination and cervical inspection), Papanicolaou (Pap) smear, clinical breast examination (CBE), and chlamydia and gonorrhea (CT/GC) screening before initiating hormonal or intrauterine contraception (IUC) for healthy women. We performed multivariable regression to identify factors associated with pelvic examination practices aligned with clinical recommendations; these recommendations classify examinations and tests as recommended or unnecessary before initiation of specific contraceptive methods.

RESULTS

The overall response rate was 51%. Most providers required blood pressure measurement before initiating each method. Unnecessary CBE, Pap smears, and CT/GC screening were required by 14% to 33% of providers across methods. Fifty-two to 62% of providers required recommended pelvic examination before IUC placement; however, 16% to 23% of providers required unnecessary pelvic examinations before non-intrauterine hormonal method initiation. Factors associated with recommendation-aligned pelvic examination practices included having a higher proportion of patients using public funding (Medicaid or other assistance) and more recently completing formal clinical training.

CONCLUSIONS

Almost half (47%) of providers did not require necessary pelvic examination before placing IUC. Conversely, many providers required unnecessary examinations and tests before contraception initiation for patients.

IMPLICATIONS

Most providers required the few recommended examinations and tests for safe contraceptive provision. Reduction of unnecessary examinations and tests may reduce barriers to contraceptive access. There are also opportunities to increase use of recommended examinations, as up to 48% of providers did not require recommended pelvic examination before IUC.

Effectiveness of clinical breast examination as a 'stand-alone' screening modality: an overview of systematic reviews

BACKGROUND

There is uncertainty about the effectiveness of clinical breast examination (CBE) and conflicting recommendations regarding its usefulness as a screening tool for breast cancer. This paper provides an overview of systematic reviews that assessed the effectiveness of CBE as a 'stand-alone' screening modality for breast cancer compared to no screening and focused on its value in low- and middle-income countries (LMICs).

METHODS

We searched MEDLINE, EMBASE, Scopus, Web of Science, and the Cochrane Database of Systematic Reviews for systematic reviews reporting the effectiveness of CBE published prior to October 29, 2019. The main outcomes assessed were mortality and down staging. The AMSTAR 2 checklist was used to assess the methodological quality of the reviews including risk of bias.

RESULTS

Eleven systematic reviews published between 1993 and 2019 were identified. There was no direct evidence that CBE reduced breast cancer mortality. Indirect evidence suggested that a well-performed CBE achieved the same effect as mammography regarding mortality despite its apparently lower sensitivity (40-69% for CBE vs 77-95% for mammography). Greater sensitivity was recorded among younger and Asian women. Moreover, CBE contributed between 17 and 47% of the shift from advanced to early stage cancer.

CONCLUSIONS

CBE merits attention from health system and service planners in LMICs where a national screening programme based on mammography would be prohibitively expensive. In particular, it is likely that considerable value would be gained from conducting implementation scientific research in countries with large numbers of Asian women and/or where younger women are at higher risk.

Determinants of screening methods utilization among Iraq/Sulaimani women

PURPOSE

This study aims to find out the participation rate of women in the utilization of screening methods to determine the relationship of sociodemographic health characteristics and breast cancer (BC) awareness with the utilization of screening methods. The authors' study aims to examine the relationship between women's belief and the utilization of screening methods.

DESIGN/METHODOLOGY/APPROACH

A cross-sectional study was conducted in three health centers from December 13, 2016 to June 12, 2017. A questionnaire was constructed for data collection about sociodemographic characteristics, screening awareness and medical and health background variables. Additionally, BC awareness measure and champion health belief model scales were used to measure women's perceptiveness about BC.

FINDINGS

Despite the awareness among 78.9% of women regarding clinical breast examination (CBE) as a screening method, only 9.5% women utilized it for screening. Due to prescription by physicians for diagnosis of BC, 23.6% women had done mammography at least once in their life. Having jobs and a good education significantly influenced the utilization of CBE as a screening method. The logistic regression analysis found that old age, family history of BC, good knowledge about BC, perceived susceptibility, low rate of perceived barriers to mammography and CBE predicted participation in screening.

ORIGINALITY/VALUE

Enhancing knowledge about BC and screening, emphasizing the susceptibility to BC and the benefits of screening will help in better participation. Importance should be given to illiterate and unemployed women.

Hispanic Men and Women's Knowledge, Beliefs, Perceived Susceptibility, and Barriers to Clinical Breast Examination and Mammography Practices in South Texas Colonias

Breast cancer is the second leading cause of cancer death among women of all ethnicities. Though the disease is not a primary concern within male populations male perceptions and beliefs of breast cancer screening may contribute to a partner's or loved one's decision to engage in regular mammograms or clinical breast examinations. The current study seeks to explore a comparative analysis of breast cancer knowledge, beliefs, susceptibility, and barriers to female breast cancer and breast cancer screening among Hispanic men and women residing in the Colonias of South Texas. Using a multistage systematic sampling design, 2,812 men and women were surveyed from the two South Texas Counties; Maverick and Val Verde. Individuals between the ages of 20 and 75 (n = 2360) were included in the analysis. T-tests and linear regression models were used to examine gender differences in, knowledge, beliefs, susceptibility, and barriers to breast cancer and breast cancer screening. Significant differences were found between males and females across all measures. Regression analysis demonstrates Hispanic women hold more favorable beliefs about breast cancer and early detection, display higher perceived barriers to clinical breast examinations and mammography, and view themselves more susceptible to the development of breast cancer than their male counterparts. Results framed within a cultural context suggest outreach efforts within South Texas Colonias should consider inclusion of male family members in efforts to increase favorable views toward and engagement in regular breast cancer screening.

Knowledge, attitudes, and practices related to breast cancer screening among female health care professionals: a cross sectional study

BACKGROUND

Incidence of breast cancer in the Kingdom of Saudi Arabia (KSA) has increased in recent years. Screening helps in early detection of cancer and early diagnosis and timely treatment of breast cancer lead to a better prognosis. Women in the healthcare profession can have a positive impact on the attitudes, beliefs, and practices of general public. Therefore, it is important that the healthcare workers themselves have adequate knowledge and positive attitudes. We conducted a study to assess the knowledge, attitudes, and practices related to breast cancer screening among female healthcare professionals.

METHODS

A cross-sectional study was conducted on female health professional of KFMC (King Fahad Medical City). Data was collected using a pre-designed, tested, self-administered questionnaire. The questionnaire included specific sections to test the participants' knowledge, attitude, and practices related to cervical cancer and its screening. Data analysis was done using descriptive statistics.

RESULTS

A total of 395 health care workers participated in this study. The mean age of the participants was 34.7 years. Participants included physicians (n = 63, 16.0%), nurses (n = 261, 66.1%), and allied health workers (n = 71, 18.0%). Only 6 (1.5%) participants had a good level of knowledge of breast cancer and 104 (26.8%) participants demonstrated a fair level of knowledge. Overall, 370 (93.7%), 339 (85.8%), and 368 (93.2%) participants had heard of breast self-examination, clinical breast examination, and mammography, respectively. A total of 295 (74.7%) participants reported practicing breast self-examination, 95 (24.1%) had undergone clinical breast examination, and 74 (18.7%) had ever undergone mammography.

CONCLUSION

The knowledge, attitudes, and practices related to breast cancer screening were found to be lower than expected. Active steps are required to develop educational programs for the health care staff, which might empower them to spread the knowledge and positively influence the attitudes of female patients in the hospital.

Effect of Health Education on Female Teachers' Knowledge and Practices Regarding Early Breast Cancer Detection and Screening in the Jazan Area: a Quasi-Experimental Study

Educational programs are important tools for breast cancer prevention. The purpose of this study was to assess the effectiveness of health education in improving the knowledge and practices of female teachers regarding screening tools and the early detection of breast cancer. A two-group quasi-experimental design was conducted among 150 female teachers, who were selected from 75 schools of the Jazan General Administration of Education. Schools were chosen by a simple cluster randomization method and non-randomly assigned to either the intervention or control group. Eligible participants were recruited by a simple randomization method, proportional to the total number of teachers at each school. Those in the intervention group (n = 75) were compared to the control group (n = 75) at baseline, as well as at 6 weeks and 3 months post-intervention. Knowledge of breast cancer screening tools was measured using a modified version of the Breast Cancer Knowledge test. Breast self-examination, clinical breast examination, and mammography practices were also measured. Compared to the control group, the intervention group showed a statistically significant increase in knowledge and practice levels at both 6 weeks and 3 months post-intervention. Thus, the results of this study provide evidence that group health education programs are effective in improving breast cancer knowledge and practices in female teachers.

Diagnostic Accuracy of Breast Medical Tactile Examiners (MTEs): A Prospective Pilot Study

Background

The usefulness of clinical breast examination (CBE) in general and in breast cancer screening programs has been a matter of debate. This study investigated whether adding vision-impaired medical tactile examiners (MTEs) improves the predictiveness of CBE for suspicious lesions and analyzed the feasibility and acceptability of this approach.

Methods

The prospective study included 104 patients. Physicians and MTEs performed CBEs, and mammography and ultrasound results were used as the gold standard. Sensitivity and specificity were calculated and logistic regression models were used to compare the predictive value of CBE by physicians alone, MTEs alone, and physicians and MTEs combined.

Results

For CBEs by physicians alone, MTEs alone, and both combined, sensitivity was 71, 82, and 89% and specificity was 55, 45, and 35%, respectively. Using adjusted logistic regression models, the validated areas under the curve were 0.685, 0.692, and 0.710 (median bootstrapped p value (DeLong) = 0.381).

Conclusion

The predictive value for a suspicious breast lesion in CBEs performed by MTEs in patients without prior surgery was similar to that of physician-conducted CBEs. Including MTEs in the CBE procedure in breast units thus appears feasible and could be a way of utilizing their skills.

Accuracy of clinical breast examination's abnormalities for breast cancer screening: cross-sectional study

OBJECTIVES

The guidelines for breast cancer screening with clinical breast examination (CBE) are diverging CBE is recommended in France, whereas it is not recommended in the United States and Canada, given the lack of clear benefit and the risk of overmedication. To assess the accuracy of abnormalities found during CBE for in breast cancer screening.

STUDY DESIGN

A cross-sectional study included women over 18 years with no history of breast cancer coming for a mammography at 3 ambulatory radiology practices in Paris. A questionnaire collected the risk of breast cancer on mammography according to the Breast Imaging-Reporting And Data System (Bi-RADS) (high risk: Bi-RADS 4 or 5 versus lower risk: other Bi-RADS categories), the risk factors for breast cancer and the breast clinical abnormalities (none, mass, skin abnormality, oedema, pain, nipple discharge, lymph nodes…) For each abnormality, sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were calculated.

RESULT

Among the 3218 included patients (mean age 55.1 +/-10 years), 713 (22.2%) had an abnormal CBE and 133 (4.1%) had high-risk mammography. The sensitivity of CBE was 36%[28%;45%] and the specificity was 78%[77%;80%]. The PPV and NPV for each clinical abnormality were low, except for nipple discharge, retraction and lymph nodes, for which the PPV were 10.5[3.7;29.9], 6.6[1.4;31.6], and 5.0[1.5;17.1], respectively, but these abnormalities were rare (0.5%, 0.2% and 0.5% respectively). These values were similar across all age groups.

CONCLUSION

The accuracy of CBE for breast cancer screening appeared to be low which did not support recommending regular CBE in France.

Towards evidence-based follow-up intervals for breast cancer survivors: Estimates of the preclinical detectable phase of contralateral second breast cancer

PURPOSE

Follow-up schemes in breast cancer survivors are predominantly consensus-based. To determine evidence-based follow-up intervals, estimates of sensitivity of the screening test(s) and duration of the preclinical detectable phase (PCDP) are key. We estimated the sensitivity and the duration of the PCDP of clinical breast examination (CBE) and mammography for the detection of contralateral second breast cancers (CBC) in breast cancer survivors.

METHODS

Women with a CBC (N = 589) diagnosed in Florence between 1980 and 2005 were included. Test sensitivity and the duration of PCDP were estimated using a simple exponential model of PCDP duration. Analyses were stratified by follow-up period (0-5 vs. >5 years after primary diagnosis) and age at CBC diagnosis (<50 vs. ≥50 years).

RESULTS

For CBE, test sensitivity was 55% and the duration of the PCDP 16 months. Mammography sensitivity was 91% and duration of the PCDP 35 months. Stratified analyses showed a higher test sensitivity for CBE for women aged <50 (70% vs. 51%). No difference in the duration of PCDP of CBE was found. For mammography, test sensitivity and the duration of the PCDP were higher for women with longer follow-up and in older women.

CONCLUSIONS

Poor test sensitivity for CBE with a shorter duration of the PCDP compared with mammography were observed. Mammography had high test sensitivity and the potential to detect CBCs early. The estimated duration of the PCDP (35 months) was considerably longer than the recommended follow-up interval (12 months). Future studies are needed to determine whether a longer follow-up interval is appropriate.

Hybrid Simulation in Teaching Clinical Breast Examination to Medical Students

Clinical breast examination (CBE) is traditionally taught to third-year medical students using a lecture and a tabletop breast model. The opportunity to clinically practice CBE depends on patient availability and willingness to be examined by students, especially in culturally sensitive environments. We propose the use of a hybrid simulation model consisting of a standardized patient (SP) wearing a silicone breast simulator jacket and hypothesize that this, compared to traditional teaching methods, would result in improved learning. Consenting third-year medical students (N = 82) at a university-affiliated tertiary care center were cluster-randomized into two groups: hybrid simulation (breast jacket + SP) and control (tabletop breast model). Students received the standard lecture by instructors blinded to the randomization, followed by randomization group-based learning and practice sessions. Two weeks later, participants were assessed in an Objective Structured Clinical Examination (OSCE), which included three stations with SPs blinded to the intervention. The SPs graded the students on CBE completeness, and students completed a self-assessment of their performance and confidence during the examination. CBE completeness scores did not differ between the two groups (p = 0.889). Hybrid simulation improved lesion identification grades (p < 0.001) without increasing false positives. Hybrid simulation relieved the fear of missing a lesion on CBE (p = 0.043) and increased satisfaction with the teaching method among students (p = 0.002). As a novel educational tool, hybrid simulation improves the sensitivity of CBE performed by medical students without affecting its specificity. Hybrid simulation may play a role in increasing the confidence of medical students during CBE.

Improving early detection of breast cancer in sub-Saharan Africa: why mammography may not be the way forward

Background and methods

The prevention and control of breast cancer in sub-Saharan Africa (SSA) is an increasingly critical public health issue. Breast cancer is the most frequent female cancer in SSA and mortality rates from this disease are the highest globally. Breast cancer has traditionally been considered a disease of high-income countries, and programs for early detection have been developed and implemented in these settings. However, screening programs for breast cancer in SSA have been less effective than in high-income countries. This article reviews the literature on breast cancer in SSA, focusing on early detection practices. It then examines the case for and against mammography and other early detection approaches for breast cancer in SSA.

Results

Women with breast cancer in SSA are younger compared with high-income countries. Most women present with advanced disease and because treatment options are limited, have poor prognoses. Delay between symptom onset and healthcare seeking is common. Engagement with early detection practices such as mammography and breast examination is low and contributes to late stage at diagnosis.

Discussion

While early detection of breast cancer through screening has contributed to important reductions in mortality in many high-income countries, most countries in SSA have not been able to implement and sustain screening programs due to financial, logistical and sociocultural constraints. Mammography is widely used in high-income countries but has several limitations in SSA and is likely to have a higher harm-to-benefit ratio. Breast self-examination and clinical breast examination are alternative early detection methods which are more widely used by women in SSA compared with mammography, and are less resource intensive. An alternative approach to breast cancer screening programs for SSA is clinical downstaging, where the focus is on detecting breast cancer earlier in symptomatic women. Evidence demonstrates effectiveness of clinical downstaging among women presenting with late stage disease.

Conclusions

Approaches for early detection of breast cancer in SSA need to be context-specific. While screening programs with mammography have been effective in high-income countries, evidence suggests that other strategies might be equally important in reducing mortality from breast cancer, particularly in low-resource settings. There is a strong argument for further research into the feasability and acceptability of clinical downstaging for the control of breast cancer in SSA.

Breast Cancer Screening: Why Can't Everyone Agree?

Screening mammography and evolving treatments have improved mortality over the last 25 years. However, breast cancer remains the second leading cause of cancer-related mortality for women in the United States. There are several contradictory recommendations regarding breast cancer screening. Familiarity with these recommendations will allow physicians to counsel their patients and ensure well-informed shared decision making.

Improving the competency of medical students in clinical breast examination through a standardized simulation and multimedia-based curriculum

PURPOSE

Clinical breast examination (CBE) is an important step in the assessment of patients with breast-related complaints. We developed a standardized simulation and multimedia-based (SSMBI) curriculum using current evidenced-based recommendations. This study aimed to determine if SSMBI training resulted in better performance (examination scores and detection of abnormal findings) than the traditional teaching method.

METHODS

Novice fourth-year medical students were exposed to the SSMBI curriculum (n = 68) or traditional (n = 52) training. The traditional group was taught by a lecture and attending weekly clinics where they had hands-on experience. The SSMBI group underwent a structured lecture followed by an instructional video and dedicated simulated teaching. Both groups were assessed through a written knowledge exam and an objective structured clinical examination (OSCE). Student's t test and χ² tests were used to assess differences in CBE technique and knoweldge.

RESULTS

Students who underwent SSMBI training had significantly higher numbers of correct answers describing the different steps and justifications of CBE. OSCE performance was significantly higher in the SSMBI group. SSMBI-trained students were more likely to complete all the necessary CBE steps compared to traditionally-trained students (88.2% vs. 28.2%, p < 0.00001). The SSMBI group was also more systematic and more likely to perform adequate inspection, palpation, examination of the nipple-areolar complex, and identify and characterize a palpable lesion (p < 0.05).

CONCLUSIONS

Formal SSMBI training is an important asset when teaching medical students how to perform a CBE. Real clinical experience is still necessary to refine this skill and the physician-patient interaction.

A longitudinal study of the prevalence and characteristics of breast disorders detected by clinical breast examination during pregnancy and six months postpartum in Ibadan, Southwestern Nigeria

Background

Breast disorders cause great anxiety for women especially when they occur in pregnancy because breast cancer is the most common cause of cancer related deaths in women. Majority of the disorders are Benign Breast Diseases (BBD) with various degrees of associated breast cancer risks. With increasing breast cancer awareness in Nigeria, we sought to determine the prevalence and characteristics of breast disorders among a cohort of pregnant women.

Methods

A longitudinal study of 1248 pregnant women recruited in their first trimester- till 26 weeks gestational age consecutively from selected antenatal clinics (ANCs), in Ibadan, Southwest Nigeria. A pretested interviewer- administered questionnaire was used to collect information at recruitment. Clinical Breast Examination (CBE) using MammaCare® technique was performed at recruitment and follow up visits at third trimester, six weeks postpartum and six months postpartum. Women with breast disorders were referred for Breast Ultrasound Scan (BUS) and those with Breast Imaging Reporting and Data System (BIRADS) ≥4 had ultrasound guided biopsy. Statistical analysis was performed using Stata version 14.

Results

Mean age of participants was 29.7 ± 5.2 years and mean gestational age at recruitment was 20.4 ± 4.4 weeks. Seventy-two participants (5.8%) had a past history of BBD and 345 (27.6%) were primigravidae. Overall, breast disorder was detected among 223 (17.9%) participants and 149 (11.9%) had it detected at baseline. Findings from the CBE showed that 208 (69.6%) of 299 breast disorders signs found were palpable lumps or thickenings in the breast, 28 (9.4%) were persistent pain, and 63 (21.1%) were abscesses, infection and mastitis. Twenty out of 127 (15.7%) participants who had BUS performed were classified as BIRADS ≥3. Lesions found by BUS were reactive lymph nodes (42.5%), prominent ducts (27.1%), fibroadenoma (9.6%), breast cysts (3.8%) and fibrocystic changes (2.5%). No malignant pathology was found on ultrasound guided biopsy.

Conclusions

Breast lump is a major breast disorder among pregnant women attending antenatal clinics in Ibadan. Routine clinical breast examination and follow up of pregnant women found with breast disorders could facilitate early detection of pregnancy associated breast cancer in low resource settings.

Screening methods (clinical breast examination and mammography) to detect breast cancer in women aged 40-49 years

Objective:

The aim of this study is to detect breast cancer rate, nodal status, tumor size, and associated risk factors using clinical breast examination (CBE) and mammography as screening tools in women aged 40–49 years.

Materials and Methods:

A total of 500 women were screened in a time period of 2 years, between the ages of 40–49 years for breast cancer. Screening tools used were CBE and mammography. Clinical history and risk factors related to breast cancer were recorded. CBE was performed to detect any breast pathology followed by mammographic screening. Breast Imaging Reporting and Data System (BI-RADS) mammographic density categories were used for reporting breast imaging on mammography. For women with dense breasts or an inconclusive mammography report, ultrasonography was performed to assess the lesion/s. Suspicious lesion was subjected to fine-needle aspiration cytology or an open surgical biopsy for a confirmatory diagnosis. Women with history of breast cancer were excluded from the study.

Results:

CBE was normal in almost 90% of the women. Screening mammography revealed Breast Imaging Reporting and Data System (BI-RADS) I and BI-RADS II in 58.4% and 34.6% of women, respectively. Only 7% of women belonged to BI-RADS III and none in BI-RADS IV category.

Conclusion:

The study findings are in agreement with the recommendations of the World Health Organization, US preventive task force and UK guidelines that recommend screening mammography in women starting at 50 years.

Perspectives and Attitudes of Jordanian Male College Students on Breast Cancer Screening

The purpose of this study is to understand the attitudes of young Jordanian men towards breast cancer screening practices. A qualitative descriptive design informed by Clendenin and Connelly was used. Thirty-seven in-depth semi-structured individual audiotaped interviews were conducted. The analysis of the men's attitudes toward breast cancer captures the perception that breast cancer is an illness that occurs mainly later in life. This was associated with the perception of negative impact of cancer diagnosis on a young woman's social status and family role. Men believed that breast cancer preventive practices must be performed in a similar context of women's religious and cultural background. Younger generations are in need for health education related to breast cancer and its screening. It is important to provide support and guidance for young men to be more involved in providing early detection of breast cancer.

Should low-income countries invest in breast cancer screening?

With the increase in incidence and mortality of breast cancer in low-income countries (LICs), the question of whether LICs should promote breast cancer screening for early detection has gained tremendous importance. Because LICs have limited financial resources, the value of screening must be carefully considered before integrating screening programs into national healthcare system. Mammography-the most commonly used screening tool in developed countries-reduces breast cancer-specific mortality among women of age group 50-69, but the evidence is not so clear for younger women. Further, it does not reduce the overall mortality. Because the women in LICs tend to get breast cancer at younger age and are faced with various competing causes of mortality, LICs need to seriously evaluate whether mammographic screening presents a good value for the investment. Instead, we suggest a special module of clinical breast examination that could provide similar benefits at a very low cost. Nevertheless, we believe that LICs would obtain a much greater value for their investment if they promote primary prevention by tobacco cessation, healthier food and healthier lifestyle campaigns instead.

The role of clinical breast examination in cancer screening for women at average risk: A mini review

As the debate about the potential benefits and harms of screening mammography continues, it is timely to consider the role of clinical breast examination in screening for women at average risk of breast cancer. This article reviews the results from clinical trials and discusses the varied recommendations around the world. It concludes that the evidence does not support routine clinical breast examination for women participating in screening mammography programs, but there may be a benefit for women not do not have mammographic screening, especially in developing nations where health literacy and 'breast awareness' levels may be lower. This review provides information for clinicians to support women who are making decisions about the increasingly complex issue of breast cancer screening.

Patterns and determinants of receipt of follow-up mammography and/or clinical examination in a cohort of Italian breast cancer survivors

Information regarding the use of mammography by breast cancer survivors is limited. This study aimed at evaluating the compliance to surveillance mammography and/or clinical breast examination and the associated factors among patients living in northern Italy. A cancer registry-based cohort of 1304 patients living in the Health Care District of Forlì was followed up for 10 years. Eighty percent of patients had a mammogram and/or clinical breast examination during the first year after treatment. The proportion decreased to 67 % at 10 years of follow-up. Three demographic characteristics were independently associated with lower odds of having an annual mammogram and/or clinical breast examination: age at diagnosis [odds ratio (OR) 0.51, 95 % confidence interval (CI) 0.41-0.63 for patients aged 65-74 years; and OR 0.14, 95 % CI 0.11-0.18, for patients ≥75 years versus patients aged <64 year]; socio-economic status (OR 0.81, 95 % CI 0.65-1.00, for deprived patients versus patients of the reference class); and hospital travel time greater than 30 min (OR 0.44, 95 % CI 0.29-0.68 versus ≤15 min). With respect to clinical and disease characteristics, lower odds were observed for patients treated with mastectomy (OR 0.79, 95 % CI 0.65-0.97), for patients diagnosed with in situ breast cancer (OR 0.68, 95 % CI 0.46-0.99) as well as with stage II + breast cancer (OR 0.77, 95 % CI 0.63-0.94), and for patients with ≥3 Elixhauser comorbidities (OR 0.43, 95 % CI 0.26-0.71). Adherence to follow-up declined over time. Knowledge of associated factors may assist in improving access to care for breast cancer survivors.

Validation of Different Techniques in Physical Examination of Breast

The majority of patients attending breast clinics are found to be suffering from benign conditions. The detailed investigations of every patient would add to the cost of care and burden the laboratories. A detailed clinical evaluation might limit the use of thorough investigations for suspicious lesions only. This cross sectional study involved the patients with various benign and malignant conditions of breast, who attended outpatient clinic and surgical ward at All India Institute of Medical Sciences, New Delhi from June 2009 to May 2011. The study started with a training of the resident (observer 2) in various breast examination techniques by a professor of surgery (observer 1), who was well trained in the discipline of breast surgery by internationally renowned breast experts. The different techniques of breast examination were validated after calculation of intra and inter-observer variation. Excellent agreement was observed between both the observers. The diagnostic accuracy ratio for most variables ranges from 0.9 to 1. The dimpling of skin on inspection had a low kappa (coefficient of agreement = 0.48) and consistency of lymph node on palpation had a kappa 0.38. All other variables showed high agreement. The present study was successful in training the resident and validating the different techniques in physical examination of breast.

Use of simulators to explore specialty recommendation for a palpable breast mass

BACKGROUND

The aim of this study was to evaluate recommendation patterns of different specialties for the work-up of a palpable breast mass using simulated scenarios and clinical breast examination models.

METHODS

Study participants were a convenience sample of physicians (n = 318) attending annual surgical, family practice, and obstetrics and gynecology (OB/GYN) conferences. Two different silicone-based breast models (superficial mass vs chest wall mass) were used to test clinical breast examination skills and recommendation patterns (imaging, tissue sampling, and follow-up).

RESULTS

Participants were more likely to recommend mammography (P < .001) and core biopsy (P < .0001) and less likely to recommend needle aspiration (P < .043) and 1-month follow-up (P < .001) for the chest wall mass compared with the superficial mass. Family practitioners were less likely to recommend ultrasound (P < .001) and obstetrics and gynecologists were less likely to recommend mammogram (P < .006) across models. Surgeons were more likely to recommend core biopsy and less likely to recommend needle aspiration across models (P < .001).

CONCLUSIONS

Recommendation patterns differed across the 2 models in line with existing practice guidelines. Additionally, differences in practice patterns between primary care and specialty providers may represent varying clinician capabilities, healthcare resources, and individual preferences. Our work shows that simulation may be used to track adherence to practice guidelines for breast masses.

Breast cancer screening: an evidence-based update

Routine screening mammography is recommended by most groups issuing breast cancer screening guidelines, especially for women 50 years of age and older. However, both the potential benefits and risks of screening should be discussed with individual patients to allow for shared decision making regarding their participation in screening, age of commencement and conclusion, and interval of mammography screening.

Preventing breast cancer in LMICs via screening and/or early detection: The real and the surreal

To review the present status of breast cancer (BC) screening/early detection in low- and middle-income countries (LMICs) and identify the way forward, an open focused search for articles was undertaken in PubMed, Google Scholar and Google, and using a snowball technique, further articles were obtained from the reference list of initial search results. In addition, a query was put up on ResearchGate to obtain more references and find out the general opinion of experts on the topic. Experts were also personally contacted for their opinion. Breast cancer (BC) is the most common cancer in women in the world. The rise in incidence is highest in LMICs where the incidence has often been much lower than high-income countries. In spite of more women dying of cancer than pregnancy or childbirth related causes in LMICs, most of the focus and resources are devoted to maternal health. Also, the majority of women in LMICs present at late stages to a hospital to initiate treatment. A number of trials have been conducted in various LMICs regarding the use of clinical breast examination and mammography in various combinations to understand the best ways of implementing a population level screening/early detection of BC; nevertheless, more research in this area is badly needed for different LMIC specific contexts. Notably, very few LMICs have national level programs for BC prevention via screening/early detection and even stage reduction is not on the public health agenda. This is in addition to other barriers such as lack of awareness among women regarding BC and the presence of stigma, inappropriate attitudes and lack of following proper screening behavior, such as conducting breast self-examinations. The above is mixed with the apathy and lack of awareness of policy makers regarding the fact that BC prevention is much more cost-effective and humane than BC treatment. Implementation of population level programs for screening/early detection of BC, along with use of ways to improve awareness of women regarding BC, can prove critical in stemming the increasing burden of BC in LMICs. Use of newer modalities such as ultrasonography which is more suited to LMIC populations and use of mHealth for awareness creation and increasing screening compliance are much needed extra additions to the overall agenda of LMICs in preventing BC.

Is clinical breast examination effective in Japan? Consideration from the age-specific performance of breast cancer screening combining mammography with clinical breast examination

BACKGROUND

There is controversy about the value of clinical breast examination (CBE) in breast cancer screening programs that include mammography.

METHODS

In Fukui Prefecture, a screening combining mammography with CBE was employed on 62,447 women from 2004 to 2009. We examined the sensitivity and specificity of mammography alone, and mammography and CBE together for each age group (40-49, 50-59, 60-69, and 70-79).

RESULTS

167 breast cancers and 49 false-negative cancers were detected during 5 years. For the combined screening, the sensitivities were 73.1, 74.1, 78.3, and 86.5 %, and the specificities were 83.8, 87.5, 89.8, and 90.9 % in the groups of 40-49, 50-59, 60-69, and 70-79 years, respectively. In the mammography-specific analysis, sensitivity decreased to 69.8 % (-3.3 %), 66.7 % (-7.7 %), 77.3 % (-1.0 %), and 83.8 % (-2.7 %) in the groups of 40-49, 50-59, 60-69, and 70-79 years, respectively. There were greater reductions in the groups of 40-49 and 50-59 years than in those of 60-69 and 70-79 years, but there was no statistically significant decrease. Specificity generally increased with increasing age and there was a significant improvement in specificity among all age groups, except that of 70-79 years.

CONCLUSIONS

Our findings suggest that there is a trade-off between sensitivity and specificity associated with CBE added to mammography. This tendency is greater in those 40-50 years of age than in those 60-70 years of age. We consider that CBE may be omitted from breast cancer screening among women aged 60 and 70 years. Furthermore, another modality to complement mammography screening in younger Japanese women is expected.

Performance of breast cancer screening methods and modality among Chinese women: a report from a society-based breast screening program (SBSP) in Shanghai

To evaluate the screening performance of individual and combined use of clinical breast examination, ultrasonography and mammography in Chinese women, we conducted a biennial breast cancer screening program among 14,464 women aged 35 to 74 years old who lived in Qibao County, Minhang district of Shanghai, China, between May 2008 and Sept 2012. All participants were submitted to clinical breast examination, and then women with positive results and all women at age of 45-69 years old were preformed breast ultrasonography and mammography. The examination results were compared against pathological findings as the gold standard of reference. A total of 66 women were diagnosed with breast cancer in the two rounds of the screening, yielding an incident rate of 194 per 100,000 person-years. The sensitivity of clinical breast examination, ultrasonography and mammography alone were 61.4%, 53.7% and 67.3%, respectively. While mammography performed better in elder age groups and hormone receptor positive disease groups, ultrasonography had a higher sensitivity in younger age group and did not differ in sensitivity by estrogen receptor or progesterone receptor status. Combined use of the two imaging examinations increased the sensitivity in almost all age groups, but had a higher sensitivity in hormone receptor positive cancers than in those negative. Our results suggest that the Qibao modality is an effective strategy for breast cancer screening among Chinese women, especially for early detection of elder and hormone receptor positive breast cancer.

Breast screening and health issues among rural females in Malaysia: how much do they know and practice?

OBJECTIVE

This study investigated rural women's knowledge of breast cancer and screening methods by ethnicity and examined the predictors of breast screening methods.

METHODS

A cross-sectional survey was conducted in 2011 in five rural districts of Perak; 959 women were interviewed using a semi-structured questionnaire. ANOVA and regression analysis were used in data analysis.

RESULTS

Women below 50 years old, of Malay ethnicity and who had secondary education scored better than those older, of Chinese ethnicity and had primary education (p<0.001). The uptake of breast self-examination (BSE), clinical breast examination (CBE) and mammogram was 59%, 51% and 6.8%, respectively. Multivariate analysis revealed knowledge of breast cancer and CBE as top predictors of BSE, being married and knowledge of breast cancer as top predictors for CBE; and CBE as the top predictor of mammography uptake. Support from husbands and family members for breast cancer screening was a predictor for CBE and BSE.

CONCLUSION

Knowledge of breast cancer and its screening uptake varies by ethnicity, location and the type of support received. Efforts and approaches to improve the women's knowledge of breast cancer and its screening uptake therefore should be customized to address the different influencing factors.

Clinical breast exam, and mammography in women referred to health centers in Tabriz, Iran

INTRODUCTION

Breast cancer is the most common cancer and the second principal cause of cancer death in women as well as the most common cause of death in Iranian women aged 35-55 years. Detection of breast cancer in its early stages is amenable to almost complete cure. Breast cancer screening comprises breast self-examination (BSE), clinical breast examination (CBE) and mammography. The study aimed to examine the performance of CBE and mammography among women referring to health centers of Tabriz, Iran.

METHODS

This was a descriptive-analytical research carried out on 400 women aged 20-50 years. The samples were chosen through random multistage sampling among health centers of Tabriz then active records of women. A questionnaire and observational checklist was used to elicit socio-demographic information and performance of women towards breast cancer screening methods. Descriptive and inferential statistics (chi-square and Fisher&rsquo;s exact test) were used to analyze the data through SPSS 13.

RESULTS

Only 19.1% of women had clinical breast examination and 3.3% had mammogram. The main reasons why women had not performed breast cancer screening were as follows: being unaware of breast screening methods, not having a breast problem and not feeling the necessity... There was a significant correlation between performing CBE and history of breast tumor and also, between performing the mammography and family history of breast cancer and history of breast tumor (P < 0.05).

CONCLUSION

The findings showed that the performance of breast cancer screening methods was not satisfactory. In addition, their performance in high risk women was very desirable than others. The presentation of imperative education about breast cancer screening methods through health staff especially in pregnancy, post-partum and even in premarriage councelling periods seems necessary.
