Abstract

Revised practice guideline 'Screening and diagnosis of breast cancer' The evidence-based revision of the practice guideline 'Screening and diagnosis of breast cancer' was necessitated by new insights, for instance on the cost-effectiveness of screening modalities other than mammography. Mammography is the only screening modality that is recommended for the general population. In the Netherlands, women from 50-75 years of age are invited for screening. However, in view of the ongoing increase in the incidence of breast cancer and of the image quality advantages of radiological digitalization, a study on the decrease of the lower age limit--preferably 45 years--is recommended. Screening with MRI is indicated for carriers of breast cancer gene mutations. Evaluation of risk factors has resulted in a rearrangement of screening recommendations, based on relative risks (RRs): screening apart from the population screening is only recommended in case the RRis 4 or more and in patients with a positive family history in case of a RR of 2 or more. Additional risks require further genetic evaluation. The 'Breast imaging reporting and data system' (BI-RADS) is now recommended for both screening and diagnostic imaging. Its application has had an impact on the triple diagnostic approach, which has now evolved into a consensus between surgeon, radiologist and pathologist. Axillary ultrasound should be carried out ifa sentinel node procedure is being considered. MRI should be included if the cancer cannot be reliably delineated on mammography or ultrasound. The increased complexity of the diagnostic work-up often means that the final diagnosis is not arrived within one day. Every effort should be made to achieve this goal within 5 working days.
