Risk of death after cancer diagnosis; shift in stage of breast cancer diagnosis
June 23, 2008Cancer patients with low socioeconomic status (SES) have more advanced cancers at diagnosis, receive less aggressive treatment, and have a higher risk of dying in the five years following cancer diagnosis, according to a new study. The study, which will appear in the August 1, 2008 issue of CANCER, a peer-reviewed journal of the American Cancer Society, supports the need to focus on SES as an underlying factor in cancer disparities by race and ethnicity.
Racial and ethnic disparities in the diagnosis and treatment of cancer and in risk of death after cancer have been documented by many studies. But the role that socioeconomic status might play, in addition to race and ethnicity, has been less well-studied
To explore the association between SES and mortality, Tim Byers, M.D. of the University of Colorado Denver and colleagues from seven states conducted the Breast, Colon, and Prostate Cancer Data Quality and Patterns of Care (POC) Study, a collaborative inquiry by seven state cancer registries within the National Program of Cancer Registries. The researchers documented compete information on cancer stage, treatment received, and 5-year mortality rates from multiple medical record sources for 13,598 cancer cases diagnosed in seven states in 1997, including 4,844 women with breast cancer, 4,332 men with prostate cancer, and 4,422 men and women with colorectal cancer. They also determined the socioeconomic status of the neighborhood of each patient by using the neighborhood-specific income and education data from the 2000 U.S. census.
Their analysis revealed that for all three types of cancers, individuals of low socioeconomic status had more advanced stages of cancer and received less aggressive treatment. For example, women of low socioeconomic status were less likely to receive radiation treatment after a lumpectomy or to receive anti-estrogen therapy when diagnosed with an estrogen receptor positive (ER+) tumor. Men with prostate cancer who were living in areas of low socioeconomic status were less likely to have been treated by prostatectomy or radiation compared to men from areas of high socioeconomic status. Chemotherapy was also less likely to be used for low socioeconomic status men and women with colorectal cancer.
For all three types of cancer, patients who lived in low SES neighborhoods were more likely to die in the five years following their cancer diagnosis than were patients in higher SES neighborhoods. A substantial proportion of this difference seemed to be due to the combined effects of this less intensive treatment and to a later stage of cancer at the time of diagnosis. While African Americans and Hispanics were more likely than non-Hispanic whites to have lived in areas of low socioeconomic status, the investigators say that the low SES factor was apparent for all racial and ethnic groups. Disparities related to socioeconomic status were not as apparent among patients aged 65 and older, perhaps because nearly everyone over age 65 is provided access to cancer screening and treatment via Medicare, regardless of their socioeconomic status.
"These findings support the need to focus on socioeconomic status as an important underlying factor in cancer disparities by race and ethnicity," the authors concluded. "We need better information on how access to health care contributes to differences in cancer outcomes by socioeconomic status in order to address the root causes of racial and ethnic cancer disparities in the United States," they added.

OUTREACH INITIATIVES LEAD TO SHIFT IN STAGE OF BREAST CANCER DIAGNOSIS IN AFRICAN AMERICAN WOMEN
A new study indicates that community education outreach and internal navigation programs lead to a significant shift in stage at diagnosis of breast cancer among African American women, with a doubling in the proportion of cases caught at the earliest stage and a nearly reciprocal drop in the proportion of cancers at most advanced stage. The research suggests that initiatives aimed at raising awareness and utilization of breast cancer screening may improve breast cancer survival rates for African American women, who have a higher risk of death from the disease compared to whites. The study is published in the August 1, 2008 issue of CANCER, a peer-reviewed journal of the American Cancer Society.
A disproportionate number of deaths from breast cancer occur in African American women, a disparity attributed to later stage of disease at diagnosis and diagnosis at an earlier age. Treatment differences may also contribute to the higher risk of mortality.
To assess the effectiveness of outreach programs on breast cancer stage among African American women, Sheryl Gabram, M.D., an Emory University surgical oncologist and director of the AVON Comprehensive Breast Center at the Georgia Cancer Center for Excellence at Grady Memorial Hospital in Atlanta, reported on a program implemented in 2001 with two components: Community Health Advocacy and Patient Navigation. The Community Health Advocacy component includes public educational programs that encourage mammography screening, teach the importance of breast self exams, and instruct individuals to see a trained healthcare provider. The Patient Navigation component involves breast cancer survivors who communicate directly with all patients who have been diagnosed with breast cancer in the AVON Breast Center. Patient Navigators (PNs) encourage patients to follow-up with recommended medical care and access needed resources such as finances, transportation, and support services.
Between 2001 and 2004, the program conducted a total of 1,148 community interventions for more than 10,000 participants. During that same time period, a total of 487 patients were identified, diagnosed, and treated for breast cancer at the AVON Comprehensive Breast Center (89 percent African American, 5 percent Caucasian, 2 percent Hispanic, and 4 percent other race/ethnicity). Dr. Gabram and her team found that there was a doubling in the proportion of Stage 0 non-invasive breast cancers (from 12.4 percent to 25.8 percent) over the study period, while the proportion of women diagnosed with Stage IV invasive breast cancers dropped from 16.8 percent to 9.4 percent.
"This reciprocal deviation of Stage 0 versus Stage IV cancers has implications on prognosis, and ultimately outcome for these women if recommended treatment guidelines are followed," the authors wrote. They, along with leadership from Emory University's Rollins School of Public Health team, are currently conducting studies to see if the Patient Navigation program successfully influences patients to accept treatment recommendations and to adhere to appointments after they are diagnosed with breast cancer. (Research has revealed that many patients with breast cancer refuse or do not receive appropriate therapy.)
The authors concluded that programs with Community Health Advocates (CHAs) who encourage mammography screening and stress the importance of early diagnosis should be jointly emphasized with the efforts of the Patient Navigators (PNs) who encourage acceptance of and adherence to treatment standards.

Socioeconomic Status, Parenting, and Child Development (Volume in the Monographs in Parenting Series) by Marc H. Bornstein (Editor), Robert H. Bradley (Editor) Socioeconomic Status, Parenting, and Child Development presents cutting-edge thinking and research on linkages among socioeconomic status, parenting, and child development. The contributors represent an array of different disciplines, and approach the issues from a variety of perspectives. Accordingly, their take on how SES matters in the lives of children varies. This volume is divided into two parts. Part I concerns the constructs and measurement of SES and Part II discusses the functions and effects of SES. Each part presents four substantive chapters on the topic followed by an interpretive and constructively critical commentary. The chapters--considered as a whole--attest to the value of systematically examining the components of SES and how each flows through an... |

Social Stratification and Divisions: Social Class in America DVD (1957) Social Class in America is a dramatized sociological experiment used to expose what class divisions mean in America. Produced in the 1950s (when class divisions were more rigid), the film captures three newborn boys from a small American town. One, Gil Ames, is the son of a wealthy manufacturer. Ted Eastwood is middle class, the son of a white collar worker. Dave Benton is the lower class son of poor parents. The three lead very different lives, for instance Gil Ames mixes mostly with men of his own kind at the Ivy League college he goes to after high school. Though the film is ostensibly about mobility, middle class Ted is the only example of someone moving vertically from one class to another. The film is quick to point out, though, that he is only perceived as higher class in New York,... |

Measuring Socioeconomic Status And Its Effects at Individual and Collective Levels: A Cross-Country Comparison (Goteborg Studies in Educational Sciences) by Yang Yang (Author) This is a Ph.D. dissertation. The main purpose of this thesis is to examine socio-economic status (SES) effects on academic achievement at individual level and school level across countries. A basic assumption is that SES is multi-dimensional and that it should be studied at multiple levels. The data analyzed in the empirical studies were taken from the IEA (International Association for the Evaluation of Educational Achievement) Reading Literacy Study (RLS, 1990-91) and the Third International Mathematics and Science Study (TIMSS, 1994-95). Reading achievement of both 9-year-olds and 14-year-olds in RLS and Math-Science achievement of 13/14-year-olds in TIMSS were used as measures of academic achievement. A set of household items from the Student Questionnaire in the two IEA Studies was... |
