Metaplastic Carcinoma of the Breast

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Metaplastic carcinoma of the breast:
    • Tends to present in patients age 60 years and older
      • Is rare in young or premenopausal women
    • Compared to IDC:
      • It has been shown to present in a higher proportion of African Americans and Hispanics
  • Metaplastic breast cancer (MBC):
    • Is more likely to be high grade but axillary node negative at presentation
    • The mean tumor size:
      •  Is about 4 cm
    • Patients with this diagnosis are also more likely to receive chemotherapy and undergo mastectomy
    • Recurrence tends to be locoregional or pulmonary:
      • And is associated with a high mortality rate
  • Future directions may include immunotherapies:
    • As MBC has a unique histology, demonstrating increased PDL-1:
      • Which may make it a good candidate for targeted therapy:
        • More research is needed on this unique tumor phenotype
