We examined the effect of routine screening on breast cancer staging by race/ethnicity.
We used a 1990 to 1998 mammography database (N = 5182) of metropolitan Denver, Colo, women to examine each racial/ethnic cohort's incident cancer cases (n = 1902) and tumor stage distribution given similar patterns of routine screening use.
Regardless of race/ethnicity, women participating in routine screenings had earlier-stage disease by 5 to 13 percentage points. After control for possible confounding factors, White women were more likely to have early-stage disease compared with Black and Hispanic women.
Lack of screening coverage in certain racial/ethnic populations has often been cited as a reason for tumor stage differences at detection. In this study, correcting for screening did not completely reduce stage differentials among Black and Hispanic women.
我们研究了常规筛查对不同种族/族裔乳腺癌分期的影响。
我们使用了科罗拉多州丹佛市1990年至1998年的乳房X光检查数据库（N = 5182），该数据库涵盖了当地女性，以检查每个种族/族裔队列中的新发癌症病例（n = 1902）以及在相似的常规筛查使用模式下肿瘤分期分布情况。
无论种族/族裔如何，参与常规筛查的女性疾病分期更早，早5至13个百分点。在控制了可能的混杂因素后，与黑人和西班牙裔女性相比，白人女性更有可能患有早期疾病。
某些种族/族裔人群筛查覆盖率低常被认为是检测时肿瘤分期存在差异的一个原因。在本研究中，校正筛查因素后，黑人和西班牙裔女性之间的分期差异并未完全消除。
