Abstract
Data were available on 14946 screening episodes 5010 FFDM and 9936 SFM Formal analysis was by logistic regression adjusting for age and calendar year FFDM is compared with SFM with reference to cancer detection rates cancers presenting as clustering microcalcifications recall rates and PPV of recallOverall detection rates were 64 cancers per thousand screens for FFDM and 28 per thousand for SFM p 0001 In women aged 50+ cancer detection was significantly higher for FFDM at 86 per thousand vs 40 per thousand p = 0002 In women 50 cancer detection was also significantly higher for FFDM at 43 per thousand vs 14 per thousand p = 002 Cancers detected as clustering microcalcifications increased from 04 per thousand with SFM to 20 per thousand with FFDM Rates of assessment recall were higher for FFDM 73 vs 50 p 0001 FFDM provided a higher PPV for assessment recall 32 cancers/364 recalls 88 than SFM 28 cancers/493 recalls 57
