Background: Research is limited on the independent and joint effects of individual- and neighborhood-level socioeconomic status (SES) on breast cancer survival across different racial/ethnic groups.
Methods: We studied individual-level SES, measured by self-reported education, and a composite neighborhood SES (nSES) measure in females (1,068 non-Hispanic whites, 1,670 Hispanics, 993 African-Americans, and 674 Asian-Americans), ages 18 to 79 years and diagnosed 1995 to 2008, in the San Francisco Bay Area. We evaluated all-cause and breast cancer-specific survival using stage-stratified Cox proportional hazards models with cluster adjustment for census block groups.
Chemotherapy regimens for early stage breast cancer have been tested by randomized clinical trials, and specified by evidence-based practice guidelines. However, little is known about the translation of trial results and guidelines to clinical practice. We extracted individual-level data on chemotherapy administration from the electronic medical records of Kaiser Permanente Northern California (KPNC), a pre-paid integrated healthcare system serving 29 % of the local population.

Patients with DLBCL (n = 1192) were less likely to receive rituximab if they were older, black or Asian, lacked private medical insurance, had impaired performance status, had no lactate dehydrogenase measurements or were diagnosed with stage I disease. Patients with FL (n = 476) were less likely to receive rituximab if they were unmarried or non-Hispanic white.

Methods: To examine age and comorbidity, Centers for Disease Control and Prevention (CDC)-funded cancer registries examined 2367 women residing in New York and Northern California diagnosed with epithelial ovarian cancer (1998-2000).
Objectives: We conducted qualitative interviews with breast cancer survivors to identify themes related to institutional, personally mediated, and internalized discrimination in the medical setting.
Methods: We conducted 7 focus groups and 23 one-on-one interviews with a multiethnic sample of breast cancer survivors randomly selected from a population-based registry covering the Greater San Francisco Bay Area, California.
Results: Participants reported experiencing different forms of medical discrimination related to class, race, and language.
Background: Clinical guidelines recommend breast-conserving surgery (BCS) with radiation as a viable alternative to mastectomy for treatment of early-stage breast cancer. Yet, Asian Americans are more likely than other groups to have mastectomy or omit radiation after BCS.
Methods: We applied polytomous logistic regression and recursive partitioning to analyze factors associated with mastectomy, or BCS without radiation, among 20,987 California Asian Americans diagnosed with stage 0 to II breast cancer from 1990 to 2007.
Research on neighborhoods and health has been growing. However, studies have not investigated the association of specific neighborhood measures, including socioeconomic and built environments, with cancer incidence or outcomes. We developed the California Neighborhoods Data System (CNDS), an integrated system of small area-level measures of socioeconomic and built environments for California, which can be readily linked to individual-level geocoded records.

To estimate subtype-specific lifetime breast cancer risks, we took advantage of population-based data for which information regarding tumor expression of estrogen receptor (ER), progesterone receptor (PR) and HER2/neu (HER2) was newly available.
Methods: We included women whose breast cancer was diagnosed in the state of California from 2006 to 2007 and was reported to the National Cancer Institute's Surveillance, Epidemiology and End Results Program (N = 40,936).
Background: Problems with cognitive function are common among older adults, yet there is little research assessing the extent to which the cognitive problems of older husbands and wives are related to those of their partners and whether any observed relationships are moderated by gender or marital quality.
Objectives: Our purpose was to analyze longitudinal relationships between older spouses' cognitive function and the cognitive function of their partners 5 years later, as well as to assess moderating roles of gender and marital quality.
Methods: The subjects were 378 community-dwelling couples aged 46-89 years at baseline who were followed for 5 years.
Objectives: We investigated heterogeneity in ethnic composition and immigrant status among US Asians as an explanation for disparities in breast cancer survival.
Methods: We enhanced data from the California Cancer Registry and the Surveillance, Epidemiology, and End Results program through linkage and imputation to examine the effect of immigrant status, neighborhood socioeconomic status, and ethnic enclave on mortality among Chinese, Japanese, Filipino, Korean, South Asian, and Vietnamese women diagnosed with breast cancer from 1988 to 2005 and followed through 2007.
Results: US-born women had similar mortality rates in all Asian ethnic groups except the Vietnamese, who had lower mortality risk (hazard ratio [HR] = 0.
Documentation of language usage in medical settings could be effective in identifying and addressing language barriers and would improve understanding of health disparities. This study evaluated the availability and accuracy of medical records information on language for 1,664 cancer patients likely to have poor English proficiency. Accuracy was assessed by comparison to language obtained from interview-based research studies.

Survival after Hodgkin lymphoma (HL) is generally favorable, but may vary by patient demographic characteristics. The authors examined HL survival according to race/ethnicity and neighborhood socioeconomic status (SES), determined from residential census-block group at diagnosis. For 12,492 classical HL patients ≥ 15 years diagnosed in California during 1988-2006 and followed through 2007, we determined risk of overall and HL-specific death using Cox proportional hazards regression; analyses were stratified by age and Ann Arbor stage.

Whether socioeconomic status (SES) can account for these differences in risk has been investigated in previous studies, but with conflicting results. Furthermore, previous studies have focused primarily on the differences between African-Americans and non-Hispanic Whites, and little is known for Hispanics and Asian/Pacific Islanders.

Racial/ethnic variation in EBV-positive HL in international comparisons suggests etiologic roles for environmental and genetic factors, but these studies used clinical series and evaluated EBV presence by differing protocols. Therefore, we evaluated EBV presence in the tumors of a large (n = 1,032), racially and sociodemographically diverse series of California incident classical HL cases with uniform pathology re-review and EBV detection methods.

Objectives: The purpose of this study was to assess the impact of older spouses' vision impairment on the health and well-being of their partners and to test for gender differences.
Methods: Participants were 418 older couples from the Alameda County Study. Vision impairment was assessed in 1994 with a 9-point scale assessing difficulty seeing in everyday situations; outcomes were assessed in 1999.
Objectives: We examined whether Medicaid beneficiaries are more likely to be diagnosed with late-stage cervical cancer than women not enrolled in Medicaid.
Methods: Using the California Cancer Registry-Medicaid linked file, we identified 4682 women diagnosed during 1996-1999 with invasive cervical cancer. Multivariate logistic regression was used to evaluate the association between late-stage diagnosis and prediagnosis Medicaid status.
Behavioral theories developed through research with mainstream, English-speaking populations have been applied to ethnically diverse and underserved communities in the effort to eliminate disparities in early breast cancer detection. This study tests the validity of the transtheoretical model (TTM) decisional balance measure and the application of the TTM stages of change in a multiethnic, multilingual sample. A random sample of 1,463 Filipino, Latino, African American, Chinese, and White women aged 40 to 74 completed a phone survey of mammography beliefs and practices.
