Performance data of screening mammography at a dedicated breast health centre
Abstract
Background. Mammographic screening has become part of routine health care. We present a first analysis of screening mammography in a dedicated breast health centre in Africa. Objective. To establish a performance benchmark and provide data for health care policy and funding decisions on screening mammography. Method. All mammography performed between January 2003 and August 2008 was entered into a prospective database. Mammography was performed exclusively by certified mammographers and double-read by experienced readers. Results. Outcomes were classified in a simplified classification system based on the Breast Imaging Reporting and Data System (BIRADS). In 40 - 49-year-old women, 3 192 mammograms led to a recall rate of 4.7%, a biopsy
rate of 1.9% and a cancer diagnosis rate of 3.8 per 1 000 examinations; for women of 50 years and older, the corresponding figures were 4 446, 5.4%, 2.6% and 9.7 per 1 000. Of the cancers detected, 31% were in situ and, of the invasive cancers, 81% were node-negative. These figures were established by a dedicated surgeon-led team and fall within
the range expected in organised screening programmes in resource-rich environments, providing a first benchmark for screening mammography in Africa.
