Routine mammography screening with clinical breast examination is effective in reducing breast cancer mortality. The Breast and Cervical Health Program (BCHP) in Washington State provides free breast and cervical cancer screening for low-income women, with an emphasis on women of color. This study examined initial breast cancer rescreening and factors associated with rescreening for women enrolled in BCHP in King County, Washington.
Data were obtained from the Washington State BCHP tracking system. We estimated the percentages who received breast cancer rescreening for women enrolled between July 1994 and December 1995 using survival analysis. Cox proportional regression was also used to examine factors associated with time-until-rescreening.
Survival analysis showed that the overall percentages rescreened at 15 and 27 months for women aged 50-69 were 25.7% and 45.0%, respectively. For women aged 40-49, the corresponding percentages were 26.0% and 40.3%. Rescreening differed by age groups, race/ethnicity, level of education, foreign born status, history of previous mammography, and enrollment clinic.
Results from this study suggested that in addition to initial efforts for enrollment, screening programs should emphasize increased rescreening especially for women with certain demographic and screening history characteristics.
常规乳腺钼靶筛查结合临床乳腺检查可有效降低乳腺癌死亡率。华盛顿州的乳腺与宫颈癌防治项目（BCHP）为低收入女性提供免费的乳腺癌和宫颈癌筛查，尤其关注有色人种女性。本研究调查了华盛顿州金县参加BCHP项目的女性的初次乳腺癌复查情况以及与复查相关的因素。
数据来源于华盛顿州BCHP追踪系统。我们使用生存分析方法估算了1994年7月至1995年12月期间登记在册的女性接受乳腺癌复查的比例。Cox比例回归分析还用于研究与复查时间相关的因素。
生存分析表明，50 - 69岁女性在15个月和27个月时接受复查的总体比例分别为25.7%和45.0%。40 - 49岁女性的相应比例分别为26.0%和40.3%。复查情况因年龄组、种族/族裔、教育程度、是否出生在国外、既往乳腺钼靶检查史以及登记诊所的不同而有所差异。
本研究结果表明，除了最初的登记工作外，筛查项目应强调增加复查，特别是针对具有特定人口统计学和筛查史特征的女性。
