Management of Early Breast Cancer Summary

  • National Comprehensive Cancer Network (NCCN) guidelines:
    • Recommend surgical management for local control:
      • For women with early stage invasive breast cancer
  • Several studies have shown an equivalence in overall and / or breast cancer-specific survival rates:
    • For breast conservation with radiation compared to mastectomy among early stage breast cancer patients
  • For patients with ER+ disease:
    • Endocrine therapy with tamoxifen or aromatase inhibitors is prescribed after surgery
  • A systematic review evaluated the efficacy of primary endocrine therapy alone versus surgery in women over 70 years old with operable tumors:
    • The review reported similar survival between the two groups:
      • But women treated with surgery had lower rates of local failure when compared to endocrine therapy alone:
        • The authors concluded that primary endocrine therapy should be reserved for women who are unfit for surgery or decline surgery
  • Sentinel node biopsy has become the standard method for staging the axilla in women with early stage breast cancer:
    • Who are clinically node negative
  • Axillary dissection:
    • Is only performed in women with documented nodal involvement, inflammatory breast cancers, or those who fail lymphatic mapping
