Women with Family History of Breast Cancer: How Much Are They Aware of Their Risk?

Establishment of a clinical cancer genetics program for breast cancer in a resource-limited country; challenges and opportunities

Breast cancer is the most common cancer among women worldwide, and its incidence rate is still increasing, especially among younger women. Nationally, it constitutes one-fifth of all cancer cases and almost 40% of all female cancers. With a median age of 51 years, breast cancer is diagnosed at least a decade earlier, and at more advanced stages compared to Western societies. Hereditary cancers account for 10% or more of all cancer burden worldwide. With expanded indications, increased number of genes tested, and significant decline in cost of testing, such proportion will probably increase. Individuals with pathogenic variants of BRCA1 and BRCA2 are at higher risk of breast, ovarian, pancreatic and many other cancers. Over the past two decades, several highly penetrant cancer-susceptibility genes were identified across almost all tumor sites, thus increasing the need for comprehensive cancer genetic programs that address the testing process, counselling patients and at-risk family members, and then deal with all testing results and its consequences. In addition to its important role in preventing more cancers in index patients themselves and among their close relatives, identification of pathogenic or likely pathogenic variants, mostly in BRCA1 or BRCA2, may inform therapeutic decisions in common cancers including breast, ovarian, prostate and pancreatic cancers. In this manuscript, we describe the experience of a comprehensive cancer center, in a resource-limited country in establishing a comprehensive clinical cancer genetics program that can serve as an example for others who share similar demographic and financial restrains.

Validation study of risk-reduction activities after personalized breast cancer education tool in the WISDOM study

Breast cancer risk reduction strategies have been well-validated, but barriers remain for high-risk individuals to adopt them. We performed a study among participants with high risk of breast cancer to validate whether a virtual breast health decision tool impacted a participant's willingness to start risk-reducing activities, identify barriers to adopting these strategies, and understand if it affects breast cancer anxiety. The study sample was 318 participants in the personalized (investigational) arm of the Women Informed to Screen Depending on Measures of risk (WISDOM) clinical trial. After reviewing the tool, these participants completed a feedback survey. We demonstrated that 15 (4.7%) women were taking endocrine risk reduction, 123 (38.7%) were reducing alcohol intake, and 199 (62.6%) were exercising. In the three-month follow-up survey of 109 respondents, only 8 of 61 (13.1%) women who considered endocrine risk reduction pursued it. In contrast, 11 of 16 (68%) participants who considered alcohol reduction pursued the activity, and 14 of 24 (58%) women who considered exercise followed through. Participants listed fear of side effects as the most common barrier to endocrine risk reduction. We also present further steps to be taken to improve the effectiveness of the Breast Health Decisions tool.

Validation of the modified Chinese Information and Support Needs Questionnaire (ISNQ-C) for daughters of mothers with breast cancer

BACKGROUND

Adult daughters concerned about getting breast cancer throughout their lives and required support because their mothers had breast cancer.

OBJECTIVES

This article aims to examine the revised Information and Support Needs Questionnaire (ISNQ) and validate it in a Taiwanese community population comprising daughters of mothers with breast cancer.

METHODS

Using convenience sampling, daughters of mothers with breast cancer were recruited and were separated into 2 samples (Sample 1, n = 102, and Sample 2, n = 118). First, we translated and modified the ISNQ to ensure cultural adaptation and formed ISNQ Chinese version (ISNQ-C). Second, we conducted an exploratory factor analysis using both samples to explore the ISNQ-C factor structure. Finally, we tested the criterion validity and known-group validity of the ISNQ-C using Sample 2.

RESULTS

Thirty-two items addressing 5 factors were identified for the ISNQ-C. Each factor had good internal consistency. The criterion validity was supported by significant correlations between the ISNQ-C scores and scores on the impacts of an event, anxiety, and depression. Known-group comparisons revealed that the group with deceased mothers reported significantly more unmet needs related to "releasing my anxiety" compared to the group where the mother was stable and undergoing regular follow-ups.

SIGNIFICANCE OF RESULTS

The ISNQ-C demonstrated good reliability and validity in terms of assessing needs among daughters of mothers with breast cancer in Taiwan. Using this assessment tool before genetic counseling to target the individual needs of this population at risk for breast cancer would be helpful to provide personalized care.

The relationship between family history of cancer and cancer attitudes & beliefs within the Community Initiative Towards Improving Equity and Health Status (CITIES) cohort

OBJECTIVE

To determine the relationship between family history of cancer with cancer attitudes and beliefs (CABs) and cancer screening knowledge.

METHODS

This study used data collected for the Community Initiative Towards Improving Equity and Health Status (CITIES) project which surveyed Ohioans ages 21-74. In the current analysis, we included data on age, gender, race, marital status, education, income, financial security, health insurance, CABs, knowledge about the correct age to begin cancer screenings, and presence of a first-degree relative with cancer. Multivariable logistic regression was used to examine the association of family history of cancer with CABs and knowledge about the correct age to begin cancer screening.

RESULTS

Participants were predominantly over the age of 41, female, and white. Out of 603 participants, 295 (48.92%) reported not having a first-degree relative with cancer and 308 (51.08%) reported having a first-degree relative with cancer. Overall, 109 (18.08%) participants reported negative CABs, 378 (62.69%) reported moderate CABs, and 116 (19.24%) reported positive CABs. Participants who reported a first-degree relative with cancer were more likely to report positive CABs, but the association was not significant (p = .11). We observed that older, more educated, and married participants were more likely to have positive CABs (all p < 0.05). Family history of cancer was not associated with differences in knowledge about the correct age for beginning colorectal cancer screening (p = .85) and mammography (p = .88).

CONCLUSIONS

Having a first-degree relative with cancer was not found to be associated with CABs or knowledge about cancer screening. However, age and socioeconomic status were associated with more positive CABs and increased knowledge about cancer screening. Future research should focus on standardizing a CABs scale and expanding the generalizability of our findings.

Racial, Lifestyle, and Healthcare Contributors to Perceived Cancer Risk among Physically Active Adolescent and Young Adult Women Aged 18-39 Years

The cancer incidence among adolescents and young adults (AYAs) has significantly increased in recent years, but there is limited information about the factors that influence the perceived cancer risk among AYAs. A cross-sectional, web-based survey of 281 physically active Black and White AYA women was administered to assess the influences of demographic characteristics, family history of cancer, cancer risk factor knowledge, and lifestyle-related risk and protective behaviors on perceived cancer risk. Linear regression analyses were performed in SAS version 9.4. Self-reported Black race (β = -0.62, 95% CI: -1.07, -0.17) and routine doctor visits (β = -0.62, 95% CI: -1.18, -0.07) were related to a lower perceived cancer risk. Family history of cancer (β = 0.56, 95% CI: 0.13, 0.99), cancer risk factor knowledge (β = 0.11, 95% CI: 0.03, 0.19), and current smoking status (β = 0.80, 95% CI: 0.20, 1.40) were related to a higher perceived cancer risk. Perceptions of cancer risk varied among this sample of physically active, AYA women. Lower perceptions of cancer risk among Black AYA women demonstrate a need for culturally tailored cancer educational information that presents objective data on lifetime cancer risk. Reportedly higher perceptions of cancer risk among AYA smokers presents an ideal opportunity to promote smoking cessation interventions. Future interventions to address cancer risk perception profiles among physically active, AYA women should tailor approaches that are inclusive of these unique characteristics.

Perceived risk and risk reduction behaviours of female first-degree relatives of breast cancer patients attending care at Uganda cancer institute

OBJECTIVE

The objective of this study was to assess the perceived risk of breast cancer (BC) and adoption of risk reduction behaviours among female first-degree relatives (FDRs) of BC patients attending care at the Uganda Cancer Institute (UCI).

METHODS

A cross-sectional study was performed using a questionnaire to collect data between March to October 2019. Adult female FDRs of patients attending care at UCI were recruited consecutively. Breast cancer perceived risk was assessed using a verbal measure; 'My chances of getting BC are great' on a Likert scale with 5 response alternatives. Chi square tests and modified Poisson regression using generalised estimating equations model were used to determine associations and examine factors associated with perceived risk of BC.

RESULTS

We enrolled 296 FDRs from 186 female BC patients. Few participants 118/296 (40%) had high perceived risk of BC. Majority 165/296 (56%), had ever practiced breast self-examination. At the multivariable modified Poisson GEE model, women aged 36-45 years were more likely to perceive themselves to be at high risk of developing BC compared to women aged 18-25 years (adjusted prevalence ratio: 1.174; 95% confidence interval [95%CI] = 1.05-2.88; p value = 0.030) after adjusting for age, religion, educational level and residence.

CONCLUSION

Few FDRs of BC patients perceived themselves to be at high risk of developing BC and do not seek risk reduction measures including screening and early diagnosis approaches. Breast cancer health education especially targeting younger women should emphasize the increased risk of BC in FDRs.

Awareness, Knowledge, Perceptions, and Attitudes towards Familial and Inherited Cancer

Background and Objectives: In 2020, the World Health Organization (WHO) reported 9.9 million deaths from cancer, with a mortality rate of 10.65%. Early detection of cancer can decrease mortality and increase the chance of cure. In Saudi Arabia, multiple studies were performed for awareness and attitudes toward cancer, but few studies evaluated the awareness of familial and inherited cancers. Materials and Methods: This is a cross-sectional observational survey of the awareness, knowledge, and attitudes of Saudi women toward familial and inherited cancers. The estimated sample size was 385. Questionnaires were distributed through social media platforms from 1 January 2021 to 22 January 2021. Results: Of the 385 participants, the majority have a bachelor’s degree. More than half (68.9%) know that family history is related to cancer, and approximately 57.2% are aware of genetic testing. The most common indication of genetic testing is premarital testing (18.5%). An inverse relationship is noted between the awareness of familial and inherited cancers and age (p = 0.003, CI = 0.723−0.938). However, awareness of inherited and familial cancer is positively associated with awareness of the association of genetic mutation to cancer (p = 0.013, CI = 1.080−1.921) and knowledge about genetic testing (p > 0.000, CI = 2.487−8.426). Conclusions: Our results reveal that Saudi women, especially older adults, have suboptimal knowledge about inherited and familial cancers, and poor attitudes toward genetic screening. We recommend increasing public awareness regarding risk factors and screening for inherited and familial cancers.

The Effect of Individual Education on the Participation of Relatives of Cancer Patients in General Health and Cancer Screenings: A One Group Pretest-Post Test Study

Objective: The aim of this study was to evaluate whether or not there were changes in the behaviors of relatives of cancer patients such as learning the warning signs of cancer, engaging in cancer prevention strategies, and participating in screenings after education sessions in the clinic. Methods: This one-group pretest-posttest study was conducted with 238 relatives in a medical oncology clinic in Antalya, Turkey. Individual education sessions were conducted as an intervention, banners were hung about cancer, and general health information on checkups in the form of leaflets were distributed to each relative regarding cancer screenings. Reminder messages were sent to individuals to participate in screenings one and two months after the first interview. The posttest data were collected by phone in the third month. Four questionnaires were prepared based on the literature and national cancer screening standards. The face validity of the tools was evaluated by three experts and 15 relatives who not included as participants. Results: The rate of having a mammography increased from 19.8% to 33.9%, rates of having the fecal occult blood test increased from 16.9% to 23.8%, and rates of having the HPV test increased from 43.5% to 49.6%. The rate of having blood pressure checks within the last 12 months increased from 75.8% to 83.1%, rates of blood cholesterol measurement increased from 68.5% to 79%, and rates of blood glucose measurement increased from 70.2% to 79%. Conclusion: Education provided to the relatives increased participation in screenings.

Developing genetic counselling services in an underdeveloped healthcare setting

Genetic counselling services are well established in North America, Western Europe and Australia. In other regions, genetic counselling services are still emerging. Where this is the case, an in-depth understanding of the main stakeholders’ needs, challenges and opportunities will inform the changes and innovations required to bring genetic counselling closer to the community. The present study explored the needs and challenges of patients, family members and professionals with a view to setting up a cancer genetic counselling service in Romania. In order to get a comprehensive outlook, key stakeholders were interviewed using data source triangulation method. Thirty-four semi-structured interviews were conducted (13 patients, 11 family members and 10 professionals). Thematic analysis was used to explore and identify needs, barriers and opportunities in emerging cancer genetic counselling services. Three major themes were identified: (1) the “Needs” theme mainly focuses on various types of support that participants mentioned wanting: psychosocial, peer and additional support; (2) the “Challenges” theme includes aspects related to limited access to healthcare, lack of integrated services and pressure on the families; (3) the “Hopes” theme highlights the wish for integrated healthcare and an empathic rapport with healthcare providers. Our findings highlighted the main needs, challenges and hopes the patients, family members and professionals have and provides the groundwork for setting up cancer genetic counselling services.

Development and validation of the MARA scale in Spanish to assess knowledge and perceived risks and barriers relating to breast cancer prevention

Objective

The aim of this study was to develop a measurement instrument for assessing knowledge of breast cancer and perceived risk of developing the disease (MARA).

Methods

641 women with a mean age of 36.19 years (SD = 7.49) participated in the study. Data collection took place during 2019 and included sociodemographic data, data on history of cancer and breast cancer, perceived risk, and feelings of concern about developing breast cancer. Internal consistency, test–retest reliability, convergent validity, and structural validity were tested.

Results

The questionnaire items comprise 4 subscales: risk factors (9 items), signs and symptoms (9 items), perceived risk (6 items), barriers (7 items). A factor analysis revealed that the first two subscales had two dimensions each, whereas the other two subscales had one dimension each. Each subscale was shown to have adequate reliability (α = 0.74–0.92) and temporal stability (r = 0.201–0.906), as well as strong evidence of validity in relation to a questionnaire on breast cancer knowledge (r = 0.131–0.434). In addition, the subscales were shown to have high discriminatory power in terms of the presence or absence of a history of cancer or breast cancer, perceived risk, and feelings of concern.

Conclusion

The MARA questionnaire represents a valid, reliable tool for assessing Spanish women’s knowledge, risks, perceptions, and barriers regarding breast cancer.

Prediction model that combines with multidisciplinary analysis for clinical evaluation of malignancy risk of solid breast nodules

Objective

Few studies have systematically developed predictive models for clinical evaluation of the malignancy risk of solid breast nodules. We performed a retrospective review of female patients who underwent breast surgery or puncture, aiming to establish a predictive model for evaluating the clinical malignancy risk of solid breast nodules.

Method

Multivariable logistic regression was used to identify independent variables and establish a predictive model based on a model group (207 nodules). The regression model was further validated using a validation group (112 nodules).

Results

We identified six independent risk factors (X₃, boundary; X₄, margin; X₆, resistive index; X₇, S/L ratio; X₉, increase of maximum sectional area; and X₁₄, microcalcification) using multivariate analysis. The combined predictive formula for our model was: Z=−5.937 + 1.435X₃ + 1.820X₄ + 1.760X₆ + 2.312X₇ + 3.018X₉ + 2.494X₁₄. The accuracy, sensitivity, specificity, missed diagnosis rate, misdiagnosis rate, negative likelihood ratio, and positive likelihood ratio of the model were 88.39%, 90.00%, 87.80%, 10.00%, 12.20%, 7.38, and 0.11, respectively.

Conclusion

This predictive model is simple, practical, and effective for evaluation of the malignancy risk of solid breast nodules in clinical settings.

Single item to assess for worry for cancer: Initial evidence of validity and reliability

OBJECTIVE

To translate into Spanish and evaluate the evidence of content validity, construct validity and reliability of the Cancer Worry Chart as a single item measure of worry for cancer.

METHOD

The Spanish translation of the Cancer Worry Chart was done with the back-translation procedure. The participants were 165 healthy people with a family history of cancer who responded to the Cancer Worry Chart and the Cancer Worry Scale (CWS).

RESULTS

Translation back-translation allows a Spanish version of the Cancer Worry Chart whose content is clear, coherent and relevant (V>.70). Evidence of construct validity is reported based on 3 criteria: (a) an adequate adjustment of the one-dimensional model formed by the Cancer Worry Chart and the items of the CWS performed with the structural equations method (χ²_S-B=23.38; df=14; χ²_S-B/df=1.67; CFI=.988; RMSEA=.064); (b) a significant correlation between the Cancer Worry Chart and the CWS (r=.76 [IC95%: .68-.90]); (c) ascending averages in the CWS score as the groups formed by each response option of the Cancer Worry Chart express a greater degree of worry (F=55.72; p=.000; ω²=.57). The reliability of the Cancer Worry Chart is above what is recommended (α_{single item}=.84).

CONCLUSION

The Spanish version of the Cancer Worry Chart showed satisfactory evidence of content validity, construct validity and reliability to measure, briefly, quickly and generally, the worry for cancer in healthy people with a family history of cancer.

Theory-based training to promote breast cancer screening among women with breast cancer worries: randomized controlled trial

BACKGROUND

Breast cancer worries are important determinants in relation to behavior favoring breast cancer screening.

OBJECTIVE

To determine the effect of theory-based training to promote breast cancer screening among women with high and low levels of breast cancer worries.

DESIGN AND SETTING

Randomized controlled trial, conducted in two family health centers.

METHODS

In total, 285 women were recruited. Women with low levels of breast cancer worries were included in the first intervention group (112 women) and the first control group (112 women), while women with high levels of breast cancer worries were included in the second intervention group (37 women) and the second control group (43 women). Theory-based training to promote breast cancer screening was given to intervention groups. The women's willingness to undergo breast cancer screening and breast cancer worry scores were evaluated at 1, 3 and 6 months.

RESULTS

The women in the low cancer-worry intervention group performed breast self-examination more in months 1 and 6 following the training, and the women in the high cancer-worry control group performed breast self-examination more in month 3 (P < 0.05). No difference between the women who had low or high levels of breast cancer worries were observed in relation to breast self-examination, clinical breast examination or mammography (P > 0.05).

CONCLUSION

The level of worry did not affect the success of theory-based training, and the training was partially effective with regard to willingness to undergo breast cancer screening.

CONCLUSION

The Spanish version of the Cancer Worry Chart showed satisfactory evidence of content validity, construct validity and reliability to measure, briefly, quickly and generally, the worry for cancer in healthy people with a family history of cancer.

Association of ATM and BMI-1 genetic variation with breast cancer risk in Han Chinese

We tested the hypothesis that genetic variation in ATM and BMI-1 genes can alter the risk of breast cancer through genotyping 6 variants among 524 breast cancer cases and 518 cancer-free controls of Han nationality. This was an observational, hospital-based, case-control association study. Analyses of single variant, linkage, haplotype, interaction and nomogram were performed. Risk was expressed as odds ratio (OR) and 95% confidence interval (CI). All studied variants were in the Hardy-Weinberg equilibrium and were not linked. The mutant allele frequencies of rs1890637, rs3092856 and rs1801516 in ATM gene were significantly higher in cases than in controls (P = .005, <.001 and .001, respectively). Two variants, rs1042059 and rs201024480, in BMI-1 gene were low penetrant, with no detectable significance. After adjustment, rs189037 and rs1801516 were significantly associated with breast cancer under the additive model (OR: 1.37 and 1.52, 95% CI: 1.10-1.71 and 1.14-2.04, P: .005 and .005, respectively). In haplotype analysis, haplotypes A-C-G-G (in order of rs189037, rs3092856, rs1801516 and rs373759) and A-C-A-A in ATM gene were significantly associated with 1.98-fold and 6.04-fold increased risk of breast cancer (95% CI: 1.36-2.90 and 1.65-22.08, respectively). Nomogram analysis estimated that the cumulative proportion of 3 significant variants in ATM gene was about 12.5%. Our findings collectively indicated that ATM gene was a candidate gene in susceptibility to breast cancer in Han Chinese.
