Standard methods reliably select patients for breast-conserving therapy (BCT). While magnetic resonance (MR) imaging finds more cancer, its routine use in BCT selection requires further study to prove clinical benefit.

Area of Science:

  • Oncology
  • Radiology
  • Surgical Oncology

Background:

  • Breast-conserving therapy (BCT) is a standard treatment for early-stage breast cancer.
  • Absolute contraindications for BCT are well-established through clinical evaluation and mammography.
  • Current selection methods achieve low local failure rates (<10% at 10 years).

Purpose of the Study:

  • To evaluate the role of magnetic resonance (MR) imaging in patient selection for BCT.
  • To determine if MR imaging improves outcomes or changes treatment decisions for BCT candidates.

Main Methods:

  • Review of clinical experience and diagnostic modalities for BCT selection.
  • Analysis of data regarding MR imaging's impact on identifying additional disease.
  • Assessment of radiotherapy's efficacy in managing MR-detected disease.

Main Results:

  • MR imaging identifies additional cancer in 10-54% of patients with localized disease.
  • This can lead to mastectomies that might not have been otherwise indicated.
  • Clinical experience suggests radiotherapy effectively controls most MR-detected disease.

Conclusions:

  • Routine use of MR imaging for BCT selection is not yet supported by evidence of clinical benefit.
  • Further studies are needed to demonstrate decreased local recurrence or fewer surgeries with MR-guided selection.
  • Current standard clinical evaluation and mammography remain reliable for BCT patient selection.
