This study examined whether Asian American women with breast cancer have tumor characteristics associated with delayed detection of their disease.
Breast cancer size and stage were examined in relation to subjects' ethnic group and birthplace, on the basis of Surveillance, Epidemiology, and End Results program data.
Asian-born Asian American women with breast cancer had a greater proportion of tumors larger than 1 cm at diagnosis (79%) than did US White women (70%) (P < .001). In contrast, the proportion of tumors larger than 1 cm among Asian American women born in the United States (67%) did not differ significantly from that among US White women.
Lower utilization of breast cancer screening by Asian-born Asian American women is probably responsible for their greater proportion of tumors larger than 1 cm relative to US White women in the study population. Interventional measures should be taken to increase the use of mammographic screening by first-generation Asian American women.
本研究调查患有乳腺癌的亚裔美国女性是否具有与疾病发现延迟相关的肿瘤特征。
基于监测、流行病学和最终结果计划数据,对乳腺癌的大小和分期与受试者的种族和出生地进行了研究。
出生于亚洲的亚裔美国乳腺癌女性在诊断时肿瘤大于1厘米的比例(79%)高于美国白人女性(70%)(P <.001)。相比之下,在美国出生的亚裔美国女性中肿瘤大于1厘米的比例(67%)与美国白人女性没有显著差异。
出生于亚洲的亚裔美国女性对乳腺癌筛查的利用率较低,这可能是她们在研究人群中肿瘤大于1厘米的比例高于美国白人女性的原因。应采取干预措施,增加第一代亚裔美国女性对乳房X线筛查的使用。
