我们估计了加州特定亚裔人群乳腺癌发病率的趋势，以确定是否存在移民身份和年龄的差异。为了计算种族和移民身份的比率，我们从加州癌症登记处获得了1998年至2004年癌症诊断的数据，并从社会安全号码中估算了26%缺失出生地信息的病例的移民身份。人口估计数来自1990年和2000年美国人口普查。美国女性的乳腺癌发病率高于外国出生的中国女性（发病率比[IRR] = 1.84; 95%置信区间[CI] = 1.72，1.96）和菲律宾女性（IRR = 1.32; 95% CI=1.20，1.44），但美国和外国出生的日本女性的乳腺癌发病率相似。美国出生的中国和菲律宾妇女谁是年轻的55岁以上的比率高于同样年龄的白色妇女。大多数群体的发病率随着时间的推移而上升，在外国出生的韩国和美国出生的菲律宾女性中，每年高达4%。从2000年到2004年，在美国出生的菲律宾妇女的比率超过了白色妇女。这些发现挑战了亚洲人乳腺癌发病率普遍较低的观念，因此需要提高认识，有针对性的癌症控制和研究，以更好地了解潜在因素。
We estimated trends in breast cancer incidence rates for specific Asian populations in California to determine if disparities exist by immigrant status and age. To calculate rates by ethnicity and immigrant status, we obtained data for 1998 through 2004 cancer diagnoses from the California Cancer Registry and imputed immigrant status from Social Security Numbers for the 26% of cases with missing birthplace information. Population estimates were obtained from the 1990 and 2000 US Censuses. Breast cancer rates were higher among US- than among foreign-born Chinese (incidence rate ratio [IRR] = 1.84; 95% confidence interval [CI] = 1.72, 1.96) and Filipina women (IRR = 1.32; 95% CI=1.20, 1.44), but similar between US- and foreign-born Japanese women. US-born Chinese and Filipina women who were younger than 55 years had higher rates than did White women of the same age. Rates increased over time in most groups, as high as 4% per year among foreign-born Korean and US-born Filipina women. From 2000–2004, the rate among US-born Filipina women exceeded that of White women. These findings challenge the notion that breast cancer rates are uniformly low across Asians and therefore suggest a need for increased awareness, targeted cancer control, and research to better understand underlying factors.
