Temporal trends in breast cancer survival by race and ethnicity: A population-based cohort study.

ABSTRACT:

Introduction

Differences in breast cancer survival by race and ethnicity are often assumed to be a fairly recent phenomenon, and are hypothesized to have arisen due to gaps in receipt of screening or therapy. The emergence of these differences in calendar time have implications for identification of their origin. We sought to determine whether breast cancer survival differences by race or ethnicity arose in tandem with the advent of screening or therapeutic advances.

Materials and methods

A cohort of women diagnosed with invasive breast cancer from 1975-2009 in 18 population-based registries were followed for five-year breast cancer cause-specific survival. Differences in survival according to race/ethnicity and estrogen receptor status were quantified in Cox proportional ha
