To describe the outcomes of breast biopsy recommendations for women screened through a mobile mammography van.
Data on all women screened through the Mobile Mammography Program in Suffolk County, Long Island, NY, from 1990 to 1994 were analyzed to determine biopsy recommendation rates, biopsy rates, positive biopsy rates, and cancer detection rates. Follow-up information was obtained from the women's physicians.
The breast cancer detection rate for women screened through the Mobile Mammography Program averaged 0.33% over a five-year period. The biopsy recommendation rate based on abnormal mammograms remained stable, at about 1% to 2%, over a five-year period, as did the rate of positive biopsies among women having biopsies (36.8% to 44.4%). For women ages 50 and older, the cancer rate in 1994 was 0.36%, while for women younger than age 50, the cancer rate was 0.25% (0.32% for all ages).
These findings show that a breast cancer screening program using a mobile van can have comparable cancer detection rates to national figures and a fairly stable biopsy recommendation rate from which follow-up resource needs can be estimated.
描述通过移动乳腺摄影车进行筛查的女性的乳腺活检建议结果。
对1990年至1994年在纽约州长岛萨福克县通过移动乳腺摄影项目进行筛查的所有女性的数据进行分析，以确定活检建议率、活检率、活检阳性率和癌症检出率。随访信息从女性的医生处获得。
通过移动乳腺摄影项目进行筛查的女性的乳腺癌检出率在五年期间平均为0.33%。基于乳房X光片异常的活检建议率在五年期间保持稳定，约为1%至2%，接受活检的女性中的活检阳性率也是如此（36.8%至44.4%）。对于50岁及以上的女性，1994年的癌症率为0.36%，而对于年龄小于50岁的女性，癌症率为0.25%（所有年龄的癌症率为0.32%）。
这些发现表明，使用移动车的乳腺癌筛查项目可以具有与全国数据相当的癌症检出率，以及相当稳定的活检建议率，据此可以估计后续资源需求。
