<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="abs1-1" sec-type="section"> <title>Background</title> <p>It remains uncertain whether MRI identification of additional foci of disease leads to improved outcome. We undertook a study to evaluate the influence of breast MRI on early and long‐term outcome.</p> </sec> <sec id="abs1-2" sec-type="section"> <title>Methods</title> <p>Among 1, 271 patients undergone breast cancer surgery between January 2005 and December 2006, 785 patients were attempted for BCS. Operative approach and radiologic findings were compared according to MRI use. We reselected 615 patients with unilateral early‐stage breast cancer treated with BCS including RT. We compared the histopathologic characteristics and outcomes according to MRI use.</p> </sec> <sec id="abs1-3" sec-type="section"> <title>Results</title> <p>In patients attempted for BCS (n = 785), re‐excision rates were not significantly different according to MRI use (<italic>P</italic> = 1.000). Conversion to mastectomy or bilateral cancer surgery were higher in MRI group (<italic>P</italic> = 0.002). The IBTR rate was higher in the non‐MRI group (<italic>P</italic> = 0.020). Difference in contralateral cancer rate and total recurrence rates failed to reach statistical significance (<italic>P</italic> = 0.168, 0.383, respectively). Multivariate study after adjustment showed no difference in recurrence rates and IBTR rates between the two groups (hazard ratios 1.34, 6.37 <italic>Ps</italic> = 0.385, 0.076).</p> </sec> <sec id="abs1-4" sec-type="section"> <title>Conclusion</title> <p>Use of MRI in patients with early‐stage breast cancer did not result in improvement of a patient's outcome.
