Early breast cancer detection improves outcomes. Sentinel node biopsy is effective, but a small false negative rate exists, necessitating careful axillary follow-up to prevent recurrence.

Area of Science:

  • Oncology
  • Surgical Pathology

Background:

  • Breast cancer screening enhances early diagnosis, often identifying small, node-negative tumors (T1).
  • Sentinel node biopsy (SNB) is standard for staging, avoiding axillary dissection in negative cases.

Purpose of the Study:

  • To evaluate the implications of false negative sentinel node biopsy rates in early breast cancer.
  • To assess the risk of axillary recurrence and the role of routine axillary dissection.

Main Methods:

  • Review of international literature on SNB false negative rates.
  • Analysis of institutional experience with SNB in selected early breast cancer patients.
  • Comparison of axillary recurrence rates versus the morbidity of axillary dissection.

Main Results:

  • International false negative SNB rates range from 4.5% to 12%; institutional rate is approximately 6%.
  • High diagnostic accuracy (98%) achieved in referral centers with strictly selected patients.
  • Axillary recurrence rates do not currently justify routine axillary dissection for staging purposes.

Conclusions:

  • While SNB is valuable, a small risk of false negatives necessitates vigilance.
  • Close axillary follow-up is recommended in cases of diagnostic uncertainty post-SNB.
  • Routine axillary dissection is not warranted solely for staging in early breast cancer.
