Reducing disparities in breast cancer survival: a Columbia University and Avon Breast Cancer Research and Care Network Symposium

Perceived Versus Actual Risk for Hypertension and Diabetes in the African American Community

Hypertension and diabetes mellitus are leading health concerns in the United States. Despite a disproportionate burden of both conditions among African Americans, it is estimated that 44% of diabetes cases and one quarter of hypertension cases within this population are undiagnosed. Lack of awareness of the risk of these conditions may hinder preventive efforts and the adoption of positive lifestyle changes. Based on the findings from a pilot study to develop and standardize uniform screening forms for hypertension and diabetes, this article reports on the perceived risk versus actual risk of developing these conditions among primarily African American participants using a community-based screening tool. Each form assessed both perceived and actual risk of diabetes and hypertension, respectively. A total of 265 hypertension and 225 diabetes screening forms were randomly selected from eight sites across the country. The risk perception of the overall study sample was similar to its actual risk for developing either condition. However, a significant proportion of individuals who scored at high risk for diabetes or hypertension were unaware of their risk for these conditions. These results suggest the need for developing culturally relevant interventions, public health education, and policies that address the risk misperceptions among this group.

Bias in the reporting of family history: implications for clinical care

Family history of cancer is critical for identifying and managing patients at risk for cancer. However, the quality of family history data is dependent on the accuracy of patient self reporting. Therefore, the validity of family history reporting is crucial to the quality of clinical care. A retrospective review of family history data collected at a community hospital between 2005 and 2009 was performed in 43,257 women presenting for screening mammography. Reported numbers of breast, colon, prostate, lung, and ovarian cancer were compared in maternal relatives vs. paternal relatives and in first vs. second degree relatives. Significant reporting differences were found between maternal and paternal family history of cancer, in addition to degree of relative. The number of paternal family histories of cancer was significantly lower than that of maternal family histories of cancer. Similarly, the percentage of grandparents' family histories of cancer was significantly lower than the percentage of parents' family histories of cancer. This trend was found in all cancers except prostate cancer. Self-reported family history in the community setting is often influenced by both bloodline of the cancer history and the degree of relative affected. This is evident by the underreporting of paternal family histories of cancer, and also, though to a lesser extent, by degree. These discrepancies in reporting family history of cancer imply we need to take more care in collecting accurate family histories and also in the clinical management of individuals in relation to hereditary risk.

What makes cancer survivor stories work? An empirical study among African American women

INTRODUCTION

Cancer survivors play a vital role in cancer control as messengers of hope and information, and advocates for prevention and screening. Understanding what makes survivor stories effective can enhance survivor-delivered programs and interventions.

METHODS

By random assignment and using a cross-classified design, 200 African American women viewed videotaped stories (n = 300) from 36 African American breast cancer survivors. Analyses examined effects of story attributes (narrative quality, health message strength), participant characteristics (ways of knowing, experience with breast cancer) and identification with the survivor on women's: (1) level of engagement in the story; (2) positive thoughts about the story; and, (3) remembering key messages about breast cancer and mammography in the story.

RESULTS

Participant characteristics were significant predictors of all three study outcomes, accounting for 27.8, 2.6 and 22.2% of their total variance, respectively. In comparison, the variability in these outcomes that could be attributed to differences in the stories was small (0.6, 1.1 and 2%, respectively). The effects of participant characteristics on level of engagement and positive thoughts were mediated by identification with the survivor.

CONCLUSIONS

The best predictor of a woman becoming engaged in a breast cancer survivor's story and having positive thoughts about the story was whether she liked the survivor and viewed her as similar to herself (i.e., identification).

IMPLICATIONS FOR CANCER SURVIVORS

Survivor stories may be most effective when audience members identify with the survivor. Finding key characteristics that can reliably match the two will advance cancer communication science and practice.

Obesity as a risk factor for development and poor prognosis of breast cancer

The evidence that obesity adversely affects women's health is overwhelming and indisputable. The risk of postmenopausal breast cancer increases with obesity; measured as weight gain, body mass index, waist-hip ratio or percent body fat. It is also established that obesity is associated with poor prognosis of breast cancer. This review examines in detail the possible mechanisms by which obesity causes poor prognosis of breast cancer such as estrogenic activity, advanced or more aggressive disease at diagnosis and high likelihood of both local and systemic treatment failure. After careful consideration of the available evidence, the author concludes that obesity contributes towards development and poor prognosis of breast cancer; therefore, weight management should be an integral part of any strategy to prevent and improve the outcome of breast cancer.

Racial and ethnic disparities in breast cancer mortality: are we doing enough to address the root causes?

Breast cancer is the most common noncutaneous malignancy and the second most lethal form of cancer among women in the United States. Mortality from breast cancer has declined since the late 1980s, but this decline has been steeper among white women compared with black women. As a result, the black:white mortality rate ratio has increased over the last two decades. Other ethnic minorities also suffer from disproportionately high breast cancer mortality rates. This review discusses the causes of racial and ethnic disparities in breast cancer mortality and describes the most common approaches to reducing these disparities. The literature suggests that outcome disparities are related to patient-, provider-, and health system-level factors. Lack of insurance, fear of testing, delay in seeking care, and unfavorable tumor characteristics all contribute to disparities at the patient level. At the provider level, insufficient screening, poor follow-up of abnormal screening tests, and nonadherence to guideline-based treatments add to outcome disparities. High copayment requirements, lack of a usual source of care, fragmentation of care, and uneven distribution of screening and treatment resources exacerbate disparities at the health system level. Although pilot programs have increased breast cancer screening among select populations, persistent disparities in mortality suggest that changes are needed at the policy level to address the root causes of these disparities.

Recruitment, genetic counseling, and BRCA testing for underserved women at a public hospital

Genetic counseling and testing for heritable susceptibility to breast cancer caused by mutations in BRCA genes are largely unavailable to underserved women in the United States. Starting in 2002 the UCSF Cancer Risk Program offered this service free of charge to poor and medically indigent women at San Francisco General Hospital (SFGH). One recruitment strategy was a single-page questionnaire in four languages administered to women waiting for mammograms at SFGH. This report analyzes our first 3 years of experience with the recruitment questionnaire and compares the patient demographics and BRCA test results at SFGH with a more typical population undergoing genetic counseling and testing at UCSF's Mt. Zion Hospital (MZH). To our knowledge this is the first comprehensive clinical service for hereditary breast cancer in a U.S. public hospital. The ethnic mix of all 350 patients counseled was Caucasian 49% (approximately 20% of Caucasians reported Ashkenazi Jewish ancestry), Latina, 26%; African American, 13%; and Asian/other, 12%. Compared to the MZH population, SFGH patients were more ethnically diverse, less educated and more likely to be unemployed. Of 72 patients tested for BRCA mutations, 51 (71%) were negative, 5 were BRCA1 positive, and 12 were BRCA2 positive. Four (1 Caucasian, 1 Latina, 2 African American) had a total of 13 BRCA variants of unknown significance (VUS). The ratio of BRCA1/BRCA2 positive SFGH patients (5/12) was reversed compared to MZH (119/91). We evaluated 4573 recruitment questionnaires and 280 (6%) were judged to represent a high risk of heritable cancer. After additional screening and referral negotiation, 74 were scheduled for counseling. We judged the recruitment questionnaire to be a feasible, efficient, and reasonably cost-effective way to identify women at high risk of hereditary cancer in a traditionally underserved population. Underserved populations present special challenges for genetic counselors because of large, geographically dispersed families, cultural taboos about cancer diagnoses, and social marginalization. Despite these complexities, the clinical service at SFGH has been well accepted by patients and staff. Our successful venture can serve as a model for other public hospitals contemplating this clinical service.

Correlates of colorectal cancer screening compliance among urban Hispanics

Colorectal cancer (CRC) is the second most common cancer among Latinos; screening can reduce mortality from CRC. The aims of this study are; to assess the current compliance with free colorectal cancer screening among Hispanic women who are participating in a national breast and cervical cancer screening program (NBCCEDP), and to examine the effects of a set of key constructs from the HBM and the TPB on compliance with the Fecal Occult Blood Test (FOBT). We consecutively recruited 950 women from among those attending an initial appointment at an NBCCEDP site in northern Manhattan, and administered a questionnaire. Patients were offered a free Hemoccult kit, alongside instructions and print materials. The rate of FOBT compliance (in kit return) was 77.3%. Fatalism remained a statistically significant influence on FOBT compliance in the multivariate models, and there was a trend for higher FOBT return among West Indies women (primarily from the Dominican Republic). The findings of this study demonstrate the feasibility and acceptability of distributing FOBT kits through an existing national program for cancer screening of women. The results justify replication in a more heterogeneous group of Hispanics, with longer-term followup.

Obesity and breast cancer: a review of the literature

A woman's build, the risk of breast cancer and its subsequent prognosis seem to be related. In most but not all case-control and prospective cohort studies, an inverse relationship has been found between weight and breast cancer among premenopausal women. However, most large epidemiological studies have found that overweight or obese women are at increased risk of developing postmenopausal breast cancer. It is suggested that higher body mass index is associated with a more advanced stage of breast cancer at diagnosis in terms of tumour size but data on lymph node status is not so consistent. All treatment modalities for breast cancer such as surgery, radiotherapy, chemotherapy and hormonal treatment may be adversely affected by the presence of obesity. The overall and disease-free survival is worse in most but not all studies of prognosis of obese pre- and postmenopausal women with breast cancer.
