“…Compared to non-Hispanic whites (NHWs), Asian Americans, as a whole, have higher gastric cancer incidence, but also have better survival outcomes [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Previous research, while not conclusive, has linked the survival advantage of Asian Americans to tumors at a more distal anatomic site, diagnosis at earlier tumor stages, diagnosis at younger ages, and more aggressive treatment approaches [6][7][8][9][10][11][12][13][14][15][16][17][18].…”

Examining the gastric cancer survival gap between Asians and whites in the United States

Background Globally, Asian countries bear a disproportionate gastric cancer burden. Asian Americans, the fastest growing minority population in the US, have higher gastric cancer survival than non-Hispanic whites (NHWs) despite higher incidence. Benefitting from uniform cancer registry standards within the US, we examine for the first time the heterogeneity in the Asian American population, which may elucidate the causes of these disparities. Methods SEER gastric cancer data from 2000 to 2012 were used to calculate 5-year survival estimates for NHWs and the six largest Asian ethnicities. Multivariate analyses were performed to identify critical prognostic factors and survival disparities between Asian groups and NHWs. Results We analyzed 33,313 NHW and 8473 Asian gastric cancer cases. All Asian groups had significantly higher 5-year survival than NHWs, at 29.8%. Among Asians, Koreans and Vietnamese had the highest and lowest survival, at 45.4% and 35.7%, respectively. The Korean survival advantage was largely attributable to relatively high proportions of localized stage and low proportions of cardia tumors. After adjusting for major prognostic factors, the survival disadvantage of NHWs, while attenuated, remained significant in comparison to all Asian groups (HR: 1.33, 95% CI: 1.24-1.43; reference: Korean). The survival disparities within the Asian groups vanished with adjustment. Conclusions This study characterizes distinctive gastric cancer survival patterns among the six major Asian groups and NHWs in the US. The favorable survival for Koreans is largely attributable to specific clinical factors, particularly stage at diagnosis. The causes of the survival disadvantage for NHWs remain elusive.

“…Although the rate is lower than the prevalence in non-Hispanic white women in USA [1], BC incidence rate for KAwomen almost doubled between 1990 and 2008 [2]. Further, KA women are 60 % more likely than non-Hispanic white women to have BC tumors ≥1 cm at diagnosis [3].…”

Web-Based Study for Improving Mammography Among Korean American Women

et al. 2015

Web-based culture-specific interventions for Korean American (KA) women to improve mammography utilization are not available. An established intervention developed to improve mammography utilizations for Korean American (KA) women was tested via the Web for its efficacy, feasibility, and acceptability. A randomized controlled trial, with a pretest-posttest control group design, was conducted with 136 KA women and their spouses. Intention to have a mammogram within the next 12 months increased significantly in the intervention group compare to controls. Among women whose mammograms had not been updated, 22 % of women in the intervention and 13 % of women in the control group obtained a mammogram at 2-month post-baseline, even though the difference was not statistically significant. The Web-based study educating couples was feasible and could improve KA women's breast cancer screening intention and behaviors. Combining off-line contact for recruitment/data collection with online intervention material could decrease the attrition rate in the future study because the attrition rate in this study was higher than the original study.

“…CRC was the second most commonly diagnosed cancer for both KA men and women from 2004 to 2008 [1]. Data from Surveillance, Epidemiology, and End Results (SEER) show that CRC incidence rates increased from 54.4 to 58.2 per 100,000 for KA men and from 35.7 to 40.9 per 100,000 for KA women from the period 1998~2002 to the period 2004~2008 [1].…”

Purpose: The purpose of this study was to report the instrument modification and validation processes to make existing health belief model scales culturally appropriate for Korean Americans (KAs) regarding colorectal cancer (CRC) screening utilization. Methods: Instrument translation, individual interviews using cognitive interviewing, and expert reviews were conducted during the instrument modification phase, and a pilot test and a cross-sectional survey were conducted during the instrument validation phase. Data analyses of the cross-sectional survey included internal consistency and construct validity using exploratory and confirmatory factor analysis. Results:The main issues identified during the instrument modification phase were (a) cultural and linguistic translation issues and (b) newly developed items reflecting Korean cultural barriers. Cross-sectional survey analyses during the instrument validation phase revealed that all scales demonstrate good internal consistency reliability (Cronbach's alpha= .72~.88). Exploratory factor analysis showed that susceptibility and severity loaded on the same factor, which may indicate a threat variable. Items with low factor loadings in the confirmatory factor analysis may relate to (a) lack of knowledge about fecal occult blood testing and (b) multiple dimensions of the subscales. Conclusion: Methodological, sequential processes of instrument modification and validation, including translation, individual interviews, expert reviews, pilot testing and a cross-sectional survey, were provided in this study. The findings indicate that existing instruments need to be examined for CRC screening research involving KAs.
