Breast Cancer Recurrences: Management

  • In general, local chest wall or nodal recurrences should be excised if feasible, and then possibly treated with systemic therapy
  • The role of chemotherapy following complete excision of isolated locoregional recurrence:
    • Was examined in the CALOR trial with the final analyses of this trial:
      • Demonstrating a 10-year disease-free survival benefit:
        • For patients with the addition of chemotherapy in ER negative recurrences:
          • But no statistically significant benefit for ER positive recurrences
  • Re-irradiation with or without hyperthermia has also been examined:
    • Vernon et al. included multiple prospective randomized trials comparing radiation alone (RT) versus hyperthermia (HT):
      • The local complete response was:
        • 59% in the combined group and 41% in the RT alone group
    • A large meta-analysis by Datta et al. combined 34 studies (8 two-arm, and 26 single-arm):
      • The complete response (CR) rate reported for the combined RT + HT for the two-arm studies was 60% vs. 38% for RT alone
  • Concurrent chemotherapy with radiation therapy has also been evaluated, in particular with chemosensitizers such as capecitabine:
    • Zagar et al. report that a combination of mild hyperthermia with a thermally sensitive doxorubicin containing liposome was safe when treating for patients with chest wall recurrences of breast cancer
