Axillary lymph node dissection (ALND) may be safely omitted for T1a breast cancer patients to reduce treatment costs and morbidity. For T1b and T1c tumors, sentinel lymph node biopsy can lower ALND

Area of Science:

  • Oncology
  • Surgical Oncology
  • Breast Cancer Research

Background:

  • Axillary lymph node dissection (ALND) is standard for staging breast cancer.
  • Sentinel lymph node biopsy (SLNB) offers a less invasive alternative, potentially reducing costs and morbidity.
  • The necessity of ALND for early-stage T1 breast cancer requires further investigation to optimize patient care.

Purpose of the Study:

  • To evaluate the incidence of lymph node metastasis in patients with T1 breast cancer.
  • To determine if ALND can be safely omitted in specific T1 tumor subtypes.
  • To identify factors influencing lymph node positivity and survival outcomes.

Main Methods:

  • Retrospective study of 423 patients with T1 breast cancer (T1a, T1b, T1c).
  • Analysis of tumor size, patient age, menopausal status, and estrogen receptor (ER) status.

  • Correlation of lymph node metastasis with treatment outcomes and survival.

    • Main Results:

    • 19% of patients had positive lymph nodes; metastasis rates were 3% for T1a, 13% for T1b, and 25% for T1c.
    • Younger age, larger tumor size, premenopausal status, and ER negativity were associated with higher node positivity.
    • No survival difference was observed between patients who underwent ALND and those who did not.

    Conclusions:

    • ALND can be safely omitted in T1a breast cancer patients, reducing treatment morbidity and expense.
    • For T1b and T1c tumors, ALND is indicated, but SLNB can mitigate associated morbidity and cost.
    • Optimizing axillary staging strategies is crucial for improving breast cancer treatment outcomes.
