“…Whereas others have recently found no association between SES and breast cancer survival in Hawaii, the gradient most typical of other states (lower survival rates among the poor) was observed there in earlier cohorts from the 1960s through 1970s. 43,44 The previously observed pattern of advantaged Hawaiian cancer survival within the United States is also consistent with this study's findings. 45 It is possible-but, we think, improbable-that other factors may account for this study's findings.…”

OBJECTIVES: Comparisons of cancer survival in Canadian and US metropolitan areas have shown consistent Canadian advantages. This study tests a health insurance hypothesis by comparing cancer survival in Toronto, Ontario, and Honolulu, Hawaii. METHODS: Ontario and Hawaii registries provided a total of 9190 and 2895 cancer cases (breast and prostate, 1986-1990, followed until 1996). Socioeconomic data for each person's residence at the time of diagnosis were taken from population censuses. RESULTS: Socioeconomic status and cancer survival were directly associated in the US cohort, but not in the Canadian cohort. Compared with similar patients in Honolulu, residents of low-income areas in Toronto experienced 5-year survival advantages for breast and prostate cancer. In support of the health insurance hypothesis, between-country differences were smaller than those observed with other state samples and the Canadian advantage was larger among younger women. CONCLUSIONS: Hawaii seems to provide better cancer care than many other states, but patients in Toronto still enjoy a significant survival advantage. Although Hawaii's employer-mandated health insurance coverage seems an effective step toward providing equitable health care, even better care could be expected with a universally accessible, single-payer system.

“…This is of particular concern for A/PI, H, and Other categories because subgroups within these categories (ie, Native American, Hawaiian, Mexican, South/Central American, Puerto Rican) have greater breast cancer mortality and poorer survival than white women. 4,44 The potential for underserved subgroups within the AA population also exists, with Caribbean women having a different screening profile than other women identified as AA. 45,46 Future analyses should disaggregate the R/E categories so that we can better understand these findings.…”

“…45,46 Future analyses should disaggregate the R/E categories so that we can better understand these findings. 11,44 The use of aggregate-based measures to assign individual SES status is suboptimal. 20 However, aggregate measures of income at the community level remains valuable because community-level predictors of SES have been shown to be a strong predictor of healthcare services and health outcomes for all individuals living in that community (both high and low income).…”

BACKGROUND. The reasons for race/ethnicity (R/E) differences in breast cancer survival have been difficult to disentangle. METHODS. Surveillance, Epidemiology, and End Results (SEER)‐Medicare data were used to identify 41,020 women aged ≥68 years with incident breast cancer between 1994–1999 including African American (2479), Hispanic (1172), Asian/Pacific Island (1086), and white women (35,878). A Cox proportional hazards model assessed overall and stage‐specific (0/I, II/III, and IV) R/E differences in breast cancer survival after adjusting for mammography screening, tumor characteristics at diagnosis, biologic markers, treatment, comorbidity, and demographics. RESULTS. African American women had worse survival than white women, although controlling for predictor variables reduced this difference among all stage breast cancer (hazards ratio [HR], 1.08; 95% confidence interval [95% CI], 0.97–1.20). Adjustment for predictors reduced, but did not eliminate, disparities in the analysis limited to women diagnosed with stage II/III disease (HR, 1.30; 95% CI, 1.10–1.54). Screening mammography, tumor characteristics at diagnosis, biologic markers, and treatment each produced a similar reduction in HRs for women with stage II/III cancers. Asian and Pacific Island women had better survival than white women before and after accounting for all predictors (adjusted all stages HR, 0.61 [95% CI, 0.47–0.79]; adjusted stage II/III HR, 0.61 [95% CI, 0.47–0.79]). Hispanic women had better survival than white women in all and stage II/III analysis (all stage HR, 0.88; 95% CI, 0.75–1.04) and stage II/III analysis (HR, 0.88; 95% CI, 0.75–1.04), although these findings did not reach statistical significance. There was no significant difference in survival by R/E noted among women diagnosed with stage IV disease. CONCLUSIONS. Predictor variables contribute to, but do not fully explain, R/E differences in breast cancer survival for elderly American women. Future analyses should further investigate the role of biology, demographics, and disparities in quality of care. Cancer 2008. © 2007 American Cancer Society.

Ethnic differences and factors related to breast cancer survival in Hawaii

Abstract: Despite an overall improvement in breast cancer survival, ethnic disparity in prognosis still exists. Other possible explanations for the differential prognosis, such as treatment, diet, genetics, obesity, oestrogen receptor and hormonal statuses need to be explored in future studies.
