Screening outcomes by risk factor and age: evidence from BreastScreen WA for discussions of risk-stratified population screening.

ABSTRACT:

Objectives

To estimate rates of screen-detected and interval breast cancers, stratified by risk factor, to inform discussions of risk-stratified population screening.

Design

Retrospective population-based cohort study; analysis of routinely collected BreastScreen WA program clinical and administrative data.

Setting, participants

All BreastScreen WA mammography screening episodes for women aged 40 years or more during 1 July 2007 - 30 June 2017.

Main outcome measures

Cancer detection rate (CDR) and interval cancer rate (ICR), by risk factor.

Results

A total of 323 082 women were screened in 1 026 137 screening episodes (mean age, 58.5 years; SD, 8.6 years). The overall CDR was 68 (95% CI, 67-70) cancers per 10 000 screens, and the overall ICR was 9.7 (95%
