AACR Hosts Cancer Disparities Conference in Miami, Fla. abstract online Sept

This year, the American Association for Cancer Research will host its third conference on the Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved at the Loews Miami Beach Hotel in Miami, Fla.

Findings presented at this year’s meeting will include:

• proven communication methods for reaching minority populations;
• strategies to increase enrollment in clinical trials;
• prognosis in lung cancer affected by race;
• breast cancer trends in Arab and Israeli Jewish women;
• the importance of social support and physical activity in survivors; and,
• socioeconomics and access to health care.
To help you plan your coverage of the conference, the program schedule is available online at

abstracts will be available on Sept. 22, 2010

Racial differences in stage at diagnosis and survival from epithelial ovarian cancer: A fundamental cause of disease approach

Social Science & Medicine

abstract:

Associations between race, socioeconomic status (SES) and health outcomes have been well established. One of the ways in which race and SES affect health is by influencing one’s access to resources, which confers ability to avoid or mitigate adverse outcomes. The fundamental cause of disease approach argues that when a new screening tool is introduced, individuals with greater resources tend to have better access to the innovation, thus benefiting from early detection and leading to better survival.  

Conversely, when there is no established screening tool, racial and SES differences in early detection may be less pronounced.

Most ovarian cancer is diagnosed at advanced stages, because of the lack of an effective screening tool and few early symptoms. However, once detected, racial differences may still be observed in mortality and survival outcomes. We examined the racial differences in diagnosis and survival among ovarian cancer cases diagnosed during 1994–1998, in Cook County, Illinois (N = 351). There were no racial differences in the stage at diagnosis: 51.7% of white and 52.9% of black women were diagnosed at later stages (III and IV). Only age was associated with the stage at diagnosis. Tumor characteristics also did not differ between white and black women. Compared to white women, black women were less likely to be married, less educated, more frequently used genital powder, had tubal ligation, and resided in higher poverty census tracts. As of December 31, 2005, 44.3% of white and 54.5% of black women had died of ovarian cancer. Controlling for known confounding variables, the hazard ratio for ovarian cancer death between black and white women was 2.2. The findings show that fundamental cause perspective provides a potential framework to explore subtleties in racial disparities, with which broader social causes may be accounted for in explaining post diagnosis racial differences.

BRCA1 and BRCA2 mutations across race and ethnicity: distribution and clinical implications

Abstract

PURPOSE OF REVIEW: To summarize evidence on the prevalence and spectrum of BRCA1 and BRCA2 BRCA1/2 mutations across racial and ethnic groups and discuss implications for clinical practice.
RECENT FINDINGS: The prevalence of BRCA1/2 mutations is comparable among breast cancer patients of African, Asian, white, and Hispanic descent: approximately 1-4% per gene. Among ovarian cancer patients in North America, BRCA1/2 mutations are present in 13-15%. Between racial/ethnic groups, there are important differences in the spectrum of BRCA1 compared with BRCA2 mutations, in BRCA1/2 variants of uncertain significance, and in the accuracy of clinical models that predict BRCA1/2 mutation carriage.
SUMMARY: Given the significant prevalence of BRCA1/2 mutations across race/ethnicity, there is a need to expand and customize genetic counseling, genetic testing, and follow-up care for members of all racial/ethnic groups.
