Regionally Recurrent Breast Cancer – Management

  • Isolated recurrent axillary disease:
    • Is an uncommon presentation of recurrence:
      • The incidence remains rare at 1% to 2%
  • It is important to stage patients with locoregional recurrences:
    • As approximately one-third:
      • Will present with synchronous distant metastasis
  • If the staging workup is negative:
    • A complete axillary dissection should be performed if possible
    • If surgical resection is not possible:
      • Systemic therapy should be offered:
        • To potentially allow surgical resection
    • Radiation should be performed if feasible for recurrences as well:
      • Depending on the prior extent of radiation delivered
  • In addition, complete breast imaging:
    • Should be performed to ensure there is no in-breast recurrence as well
  • The use of systemic therapy should be offered after a multidisciplinary discussion taking into account tumor phenotype and prior therapies already received by the patient
  • Wapnir et al:
    • Demonstrated in the CALOR trial that in ER negative (ER-) isolated recurrences:
      • Systemic chemotherapy improved disease-free survival:
        • However, in ER+ recurrences:
          • Endocrine therapy should be the preferred therapy
