This study examined times to diagnosis and treatment for medically underserved women screened for breast cancer.
Intervals from first positive screening test to diagnosis to initiation of treatment were determined for 1659 women 40 years and older diagnosed with breast cancer.
Women with abnormal mammograms had shorter diagnostic intervals than women with abnormal clinical breast examinations and normal mammograms. Women with self-reported breast symptoms had shorter diagnostic intervals than asymptomatic women. Diagnostic intervals were less than 60 days in 78% of cases. Treatment intervals were generally 2 weeks or less.
Most women diagnosed with breast cancer were followed up in a timely manner after screening. Further investigation is needed to identify and then address factors associated with longer diagnostic and treatment intervals to maximize the benefits of early detection.
本研究调查了接受乳腺癌筛查的医疗服务不足女性的诊断和治疗时间。
确定了1659名40岁及以上被诊断为乳腺癌的女性从首次阳性筛查试验到诊断再到开始治疗的时间间隔。
乳房X光检查异常的女性诊断间隔比临床乳房检查异常但乳房X光检查正常的女性短。自我报告有乳房症状的女性诊断间隔比无症状女性短。78%的病例诊断间隔少于60天。治疗间隔一般为2周或更短。
大多数被诊断为乳腺癌的女性在筛查后得到了及时随访。需要进一步调查以识别并解决与较长诊断和治疗间隔相关的因素,以最大限度地提高早期检测的益处。
