“…This trend contrasts with stable or declining trends among other racial/ethnic groups, but is similar to increasing trends in South Korea, China, Taiwan, Japan, and Hong Kong. In age-period-cohort analyses, Sung et al (11) and Wang et al (19) found dramatically increasing trends of breast cancer incidence (11) and mortality (19) in recent cohorts in Asia, with incidence rates through 2009 surpassing those of US NHW women (11). These authors attributed increases to increasing prevalence among Asian women of established reproductive breast cancer risk factors.…”

“…Moreover, several studies have shown that rates in AA women differ by age and nativity, with higher rates among young US-born AA women (8–10). Rapidly increasing incidence rates also have been noted in Asian countries, and international data suggest that among more recent generations, rates in Asian countries may be surpassing rates in the US, particularly those for white women (11). …”

Purpose In contrast to other US racial/ethnic groups, Asian Americans (AA) have experienced steadily increasing breast cancer rates in recent decades. To better understand potential contributors to this increase, we examined incidence trends by age and stage among women from seven AA ethnic groups in California from 1988 through 2013, and incidence patterns by subtype and age at diagnosis for the years 2009 through 2013. Methods Joinpoint regression was applied to California Cancer Registry data to calculate annual percentage change (APC) for incidence trends. Incidence rate ratios were used to compare rates for AA ethnic groups relative to non-Hispanic whites (NHW). Results All AA groups except Japanese experienced incidence increases, with the largest among Koreans in 1988–2006 (APC: 4.7, 95% CI: 3.8, 5.7) and Southeast Asians in 1988–2013 (APC: 2.5, 95% CI: 0.8, 4.2). Among women younger than age 50, large increases occurred for Vietnamese and other Southeast Asians; among women over age 50, increasing trends occurred in all AA ethnic groups. Rates increased for distant stage disease among Filipinas (2.2% per year, 95% CI: 0.4, 3.9). Compared to NHW, Filipinas and older Vietnamese had higher incidence rates of some HER2+ subtypes. Conclusions Breast cancer incidence rates have risen rapidly among California AA, with the greatest increases in Koreans and Southeast Asians. Culturally-tailored efforts to increase awareness of and attention to breast cancer risk factors are needed. Given the relatively higher rates of HER2-overexpressing subtypes in some AA ethnicities, research including these groups and their potentially unique exposures may help elucidate disease etiology.

“…In the USA, breast cancer mortality rates decreased by 36% between 1989 and 2012 [22]. Sung et al [23] found comparable longitudinal breast cancer age-specific incidence rates (ASR) among Asian and Western populations. Taiwan implemented a stratified breast cancer screening program in 1995 [24].…”

Epidemiology and survival outcome of breast cancer in a nationwide study

et al. 2017

Breast cancer is among the most prevalent cancers in Taiwan. The National Health Insurance database was used to identify patients with breast cancer and estimate the yearly prevalence and incidence of breast cancer between 1997 and 2013. Joinpoint regression analysis was used for the annual percentage change of incidence, prevalence, and survival outcome. Among 12,181,919 female beneficiaries in 2013, the prevalence was 834.37 per 100,000 persons (95% confidence interval, 829.28–839.45) and the incidence was 93.00 per 100,000 person-year (95% confidence interval, 91.27–94.73). The average annual percentage change of the age-standardized breast cancer incidence was 3.5 per 100,000 person-years (3.1–3.8; P < 0.05), suggesting an increase in breast cancer incidence over the study period. The 5-year mortality rate was 4.5% in 1997 and 4.4% in 2008. The 5-year mortality rate among patients with Charlson comorbidity index > 1 was 39.1% (19.2%–59.1%) in 1997 and 21.1% (15.7%-32.0%) in 2008, with an annual percentage change of –0.8 (–1.3 to 2.9), suggesting that the mortality rate was gradually decreasing in patients with comorbidities. In conclusion, 1 in 120 women in Taiwan has breast cancer and the incidence is rising, while the annual percentage change of breast cancer prevalence is decreasing. The mortality rate of breast cancer was essentially stable, but the 1-year, 2-year, and 5-year mortality rates in people with Charlson comorbidity index > 1 were declined.

“…41 Studies that compare invasive breast cancer data from Asia with those from the United States over a 20-year period have shown that female breast cancer incidence among Asian and Western populations is more similar than expected. 42 The incidence of female breast cancer in China will continue to rise, and is expected to exceed 100 per 100 000 women by 2021, giving a total of 2.5 million cases. 43 According to GLOBOCAN 2012 of the International Agency for Research on Cancer, the specialised cancer research agency of the World Health Organization, almost a quarter (24%) of all breast cancers were diagnosed within the AsiaPacific region, with the greatest number occurring in China (46%).…”
