On the importance of being ethnic: Coping with the threat of prostate cancer in relation to prostate cancer screening

Validity of Race, Ethnicity, and National Origin in Population-based Cancer Registries and Rapid Case Ascertainment Enhanced With a Spanish Surname List

BACKGROUND

Accurate information regarding race, ethnicity, and national origins is critical for identifying disparities in the cancer burden.

OBJECTIVES

To examine the use of a Spanish surname list to improve the quality of race-related information obtained from rapid case ascertainment (RCA) and to estimate the accuracy of race-related information obtained from cancer registry records collected by routine reporting.

SUBJECTS

Self-reported survey responses of 3954 participants from California enrolled in the Cancer Care Outcomes Research and Surveillance Consortium.

MEASURES

Sensitivity, specificity, positive predictive value, and percent agreement. We used logistic regression to identify predictors of underreporting and overreporting of a race/ethnicity.

RESULTS

Use of the Spanish surname list increased the sensitivity of RCA for Latino ethnicity from 37% to 83%. Sensitivity for cancer registry records collected by routine reporting was ≥95% for whites, blacks, and Asians, and specificity was high for all groups (86%-100%). However, patterns of misclassification by race/ethnicity were found that could lead to biased cancer statistics for specific race/ethnicities. Discordance between self-reported and registry-reported race/ethnicity was more likely for women, Latinos, and Asians.

CONCLUSIONS

Methods to improve race and ethnicity data, such as using Spanish surnames in RCA and instituting data collection guidelines for hospitals, are needed to ensure minorities are accurately represented in clinical and epidemiological research.

Doctor-patient communication: a study of Australian ethnic urological cancer patients

Purpose

– The purpose of this paper is to examine doctor-patient communication, focusing on ethnic Australian urological cancer patients.

Design/methodology/approach

– Samples of 50 Australian urological cancer patients of ethnic origin were chosen to participate in this study. The patients completed a 31-question survey, followed by a one-on-one semi-structured 30-40-minute interview with the patient.

Findings

– Most (90 per cent,n=45) of the patients indicated that they can communicate with their doctor without feeling stereotyped or judged. However, despite these responses 48 per cent (n=24) of the patients reported they did not ask for the doctor to explain the medical terms or meanings they did not understand. This resulted in 46 per cent (n=23) of the patients not knowing the stage of their cancer.

Research limitations/implications

– This is only a pilot study and the sample was limited to 50 patients. The limitations of this study make the results of the findings more suggestive rather than definitive. Further research would benefit by repeating this study with a larger sample size, to address the shortcomings of the study and to venture further into the realm of doctor and overseas patients communication in Australia.

Practical implications

– This research found that patients from lower socioeconomic backgrounds for whom English is not their first language have low levels of medical literacy and therefore require additional written information about their illness and treatment such as informative brochures, educational booklets and educational videos on their illness.

Originality/value

– To the knowledge, this is the first study that focuses on ethnic Australian urological cancer patients and their doctor-patient communication.

Beyond the black box: a systematic review of breast, prostate, colorectal, and cervical screening among native and immigrant African-descent Caribbean populations

Cancer screening disparities between black and white groupings are well-documented. Less is known regarding African-descent subpopulations despite elevated risk, distinct cultural backgrounds, and increasing numbers of Caribbean migrants. A systematic search of Medline, Web of Science, PubMed and SCOPUS databases (1980-2012) identified 53 studies reporting rates of breast, prostate, cervical, and colorectal screening behavior among immigrant and non-immigrant Caribbean groups. Few studies were conducted within the Caribbean itself; most work is US-based, and the majority stem from Brooklyn, New York. In general, African-descent Caribbean populations screen for breast, prostate, colorectal, and cervical cancers less frequently than US-born African-Americans and at lower rates than recommendations and guidelines. Haitian immigrants, in particular, screen at very low frequencies. Both immigrant and non-immigrant African-descent Caribbean groups participate in screening less frequently than recommended. Studying screening among specific Caribbean groups of African-descent may yield data that both clarifies health disparities between US-born African-Americans and whites and illuminates the specific subpopulations at risk in these growing immigrant communities.

Ethnic identity: similarities and differences in white groups based on cultural practices

The present study examined variability in ethnic identity among the ethnic groups that comprise the White racial category. Based on participants' ethnic self-labels, high school and college students (n = 495) were assigned to one of six groups: Armenian, Greek, Jewish, European, Mixed White ancestry ("Irish and Italian"), and Pan-ethnic ("White"). Individuals who identified with Specific White groups (Armenian, Greek, Jewish) had higher ethnic identity scores than individuals who identified with Nonspecific White groups (European, Mixed, Pan-ethnic). Specific White groups also had more heritage education, ethnic language competency, and religious participation than Nonspecific White groups. Regression analyses indicated that ethnic language competency and religious participation positively predicted ethnic identity for both Specific and Nonspecific White groups, controlling for age, sex, and generation. For the Specific White group, heritage education interacted with ethnic language to increase ethnic identity for students with low (but not medium or high) competency.

Ethnic, racial and cultural identity and perceived benefits and barriers related to genetic testing for breast cancer among at-risk women of African descent in New York City

BACKGROUND

Due to disparities in the use of genetic services, there has been growing interest in examining beliefs and attitudes related to genetic testing for breast and/or ovarian cancer risk among women of African descent. However, to date, few studies have addressed critical cultural variations among this minority group and their influence on such beliefs and attitudes.

METHODS

We assessed ethnic, racial and cultural identity and examined their relationships with perceived benefits and barriers related to genetic testing for cancer risk in a sample of 160 women of African descent (49% self-identified African American, 39% Black-West Indian/Caribbean, 12% Black-Other) who met genetic risk criteria and were participating in a larger longitudinal study including the opportunity for free genetic counseling and testing in New York City. All participants completed the following previously validated measures: (a) the multi-group ethnic identity measure (including ethnic search and affirmation subscales) and other-group orientation for ethnic identity, (b) centrality to assess racial identity, and (c) Africentrism to measure cultural identity. Perceived benefits and barriers related to genetic testing included: (1) pros/advantages (including family-related pros), (2) cons/disadvantages (including family-related cons, stigma and confidentiality concerns), and (3) concerns about abuses of genetic testing.

RESULTS

In multivariate analyses, several ethnic identity elements showed significant, largely positive relationships to perceived benefits about genetic testing for breast and/or ovarian cancer risk, the exception being ethnic search, which was positively associated with cons/disadvantages, in general, and family-related cons/disadvantages. Racial identity (centrality) showed a significant association with confidentiality concerns. Cultural identity (Africentrism) was not related to perceived benefits and/or barriers.

CONCLUSIONS

Ethnic and racial identity may influence perceived benefits and barriers related to genetic testing for breast and/or ovarian cancer risk among at-risk women of African descent. Genetic counseling services may want to take into account these factors in the creation of culturally-appropriate services which best meet the needs of this heterogenous population.

Psychosocial influences on suboptimal adjuvant breast cancer treatment adherence among African American women: implications for education and intervention

Despite lower incidence, African American women are at increased risk of dying from breast cancer relative to their European American counterparts. Although there are key differences in both screening behavior and tumor characteristics, an additional part of this mortality difference may lie in the fact that African American women receive suboptimal adjuvant chemotherapy and may receive suboptimal hormonal therapy, therapies that are known to increase survival. The authors consider ethnic differences in the psychosocial factors that have been shown to relate to poor screening adherence and consider how they may influence adherence to breast cancer adjuvant treatment, thus the receipt of suboptimal adjuvant chemo or hormonal therapy. To this end, they review ethnic differences in cognitive, emotional, and social network variables. Psychosocial variables should be included in research designed to understand cancer disparities as well interventions that can be tailored to culturally diverse populations to improve treatment adherence.

Determinants of prostate cancer stage in northern New England: USA Franco-American contextual effects

Despite screening for prostate cancer, mortality in the United States remains substantial. In northern New England, we know little about either determinants of stage at diagnosis--an important predictor of survival--or health outcomes for Franco-Americans, the region's largest ethnic minority. The objective of this investigation was to identify predictors of late prostate cancer stage in a rural, predominantly white state with a large Franco-American population. The Maine Cancer Registry provided incident cases from 1995 to 1998. We modeled individual-level variables (age, sex, race, French ethnicity by surname, and payer) and contextual/town-level variables (socioeconomic measures, population density, Franco ancestry proportion, distance to health care, and weather severity) with multiple logistic regression for late stage. We found that age categories 50-64, 65-74, and 75-84 years--but not 40-49 years--(versus 85+) were protective for late stage, as was residence in higher snowfall areas. Diagnosis in the earlier years of the study, particularly for French-surnamed men, and residence in a high-Franco area conferred greater risk for late disease. However, in a two-way interaction, residence in towns with high Franco ancestry proportion protected French-surnamed men (OR=0.09, type 3 p<0.0593). Using an established framework for social network theory we explore the potential reasons for this interaction, including: high social cohesion, a wide range of strong ties of long duration, and frequent contact, which might have facilitated access to resources as well as social support and normative influences toward health care seeking. The absence of an association of cancer stage with socioeconomic variables may stem from the mixed sociodemographic profiles in rural and urban regions of Maine. We feel that further research should therefore refine these and other contextual measures to elucidate effects on preventable morbidity and mortality; expand our knowledge of Franco-American health outcomes and social networks; and evaluate the utility of assigning French ethnicity by surname.
