Mantle Field Radiation / MRI in Women at High Risk for Breast Cancer

  • Receipt of mantle field radiation before the age of 30:
    • Is associated with a significantly increased risk of breast cancer compared to the general population
  • Patients with a history of Hodgkin’s lymphoma treated with mantle field radiation therapy:
    • Are more likely to be diagnosed with:
      • Breast cancer at a younger age
      • Have hormone receptor negative breast cancer
      • And have a second breast cancer
  • Because the increased risk of breast cancer has been seen as early as 8 years following receipt of radiation therapy:
    • High risk screening after mantle field radiation therapy:
      • Should begin at the age of 25 or
      • 8 years after radiation therapy
        • Whichever occurs later
  • The estimated cumulative incidence of breast cancer by the age of 50 among patients with a history of Hodgkin’s lymphoma treated with mantle field radiation therapy is:
    • 35%
  • Among all women at high risk for breast cancer (lifetime risk greater than 20%):
    • Annual screening MRI:
      • Has been associated with 77% to 100% sensitivity for detecting a new cancer
      • While mammography is associated with 16% to 40% sensitivity
  • In 2007, the American Cancer Society convened an expert panel to review the evidence on MRI screening as an adjunct to annual mammography for women at high risk of developing breast cancer:
    • Annual screening MRI is recommended for patients with:
      • A clinical history of chest radiation between the ages of 10 and 30 years
    • As well as women with a known BRCA mutation
    • Untested first-degree relatives of BRCA mutation carriers
    • Those with other genetic mutations increasing breast cancer risk
    • Women with a greater than 20% lifetime risk secondary to family history
  • The addition of bilateral breast ultrasound to a screening regimen of mammography and MRI:
    • Is associated with a substantial increase in false positives:
      • Leading to additional biopsies with no incremental benefit over mammography and MRI alone
  • There is insufficient evidence to recommend for or against:
    • Annual screening breast MRI:
      • In women who have a history of:
        • Lobular carcinoma in situ
        • Atypical lobular hyperplasia
        • Atypical ductal hyperplasia
  • There is no evidence to support MRI:
    • In women with a less than 15% lifetime risk of breast cancer
    • In women with dense breast tissue
    • In women with a personal history of breast cancer
