To report the results of the NHS breast screening programme for the year March 1991 to April 1992.
A report of statistics was derived from Körner (K62) returns and from the radiology quality assurance programme.
Detection rates for breast cancer and small (< or = 10 mm diameter) invasive cancer, benign biopsy rates, and recall and acceptance rates.
The acceptance rate for screening across the United Kingdom was 71.3%. The referral rate for further investigation was 6.2% (regional 4.3-9.0%). The breast cancer detection rate was 6.2 cancers per 1000 women screened (5.1-9.0) and the detection rate of invasive cancers < or = 10 mm was 1.4/1000 (1.0-2.3). 72% of screening programmes reached the target 70% acceptance rate, and 95% of programmes achieved a recall rate of less than 10%. 75% of programmes had a cancer detection rate of more than 5/1000, but only 32% had a detection rate for invasive cancers < or = 10 mm of more than 1.5/1000.
Overall, the results of the screening programme for the year 1991-2 can be regarded as extremely satisfactory, given the size and complexity of the operation.
报告1991年3月至1992年4月国民健康服务体系乳腺筛查项目的结果。
一份统计报告源自科纳（K62）报表以及放射学质量保证项目。
乳腺癌及小（直径≤10毫米）浸润性癌的检出率、良性活检率、召回率及接受率。
全英国的筛查接受率为71.3%。进一步检查的转诊率为6.2%（各地区为4.3%-9.0%）。每1000名接受筛查的女性中乳腺癌检出率为6.2例（5.1-9.0），直径≤10毫米的浸润性癌检出率为1.4/1000（1.0-2.3）。72%的筛查项目达到了70%的接受率目标，95%的项目召回率低于10%。75%的项目癌症检出率超过5/1000，但只有32%的项目直径≤10毫米的浸润性癌检出率超过1.5/1000。
总体而言，鉴于该项目规模和复杂性，1991 - 1992年筛查项目的结果可被视为极其令人满意。
