A simple way to measure the burden of interval cancers in breast cancer screening.

ABSTRACT:

Background

The sensitivity of a mammography program is normally evaluated by comparing the interval cancer rate to the expected breast cancer incidence without screening, i.e. the proportional interval cancer rate (PICR). The expected breast cancer incidence in absence of screening is, however, difficult to estimate when a program has been running for some time. As an alternative to the PICR we propose the interval cancer ratio ICR=intervalcancersintervalcancers+screendetectedcancers. We validated this simple measure by comparing it with the traditionally used PICR.

Method

We undertook a systematic review and included studies: 1) covering a service screening program, 2) women aged 50-69 years, 3) observed data, 4) interval cancers, women screened, or interval cancer rate, sc
