The association between intrinsic breast cancer subtypes, mammography screening and prognosis: a large population-based real world cohort study.

ABSTRACT:

Introduction

Breast cancer (BC) as a heterogeneous disease is routinely managed according to its intrinsic subtypes. Mammographic BC screening reduces overall mortality in females. Our aim was to analyze the association between different intrinsic subtypes and mammography screening coverage (pre-screening-aged, screening-aged vs. post-screening-aged), attendance (attendance vs. non-attendance), and means of detection (screen-detected vs. interval BC) and BC survival.

Materials and methods

We used a subpopulation of a registry including all patients diagnosed with invasive BC in Finland between 1995 and 2013. We collected screening results, information on biological characteristics and survival from national registries.

Results

We included 7389 patients with early-stag
