Trends in use of magnetic resonance imaging and partial breast irradiation between 2011-2022 in the Netherlands: A population-based study.

ABSTRACT:

Purpose

This study aimed to investigate whether the introduction of partial breast irradiation (PBI) was associated with increased MRI use in the Netherlands from 2011 to 2022, and examined the impact of MRI on treatment and outcomes.

Methods

Women aged ≥50 who underwent surgery (without preoperative systemic therapy) for cT1-2N0M0 breast cancer or DCIS between 2011 and 2022 were selected from the Netherlands Cancer Registry. Logistic regression was used to analyze associations between MRI and treatment or surgical radicality, stratified by tumour type. Subgroup analyses were performed in patients meeting ASTRO PBI criteria (unifocal cT1, grade 1/2, ER-positive, pure DCIS ≤ 2,5 cm).

Results

Among 119,768 patients, 35,863 (30 %) received MRI, increasing from 24 % (2011
