Sentinel lymph node biopsy is a standard for early breast cancer staging. Recent developments show subareolar injection is effective, and further research is ongoing for advanced stages and specific cancer types.

Area of Science:

  • Oncology
  • Surgical Pathology
  • Breast Cancer Research

Background:

  • Sentinel lymph node biopsy (SLNB) is a standard procedure for staging axillary lymph nodes in breast cancer patients.
  • Despite its acceptance, questions persist regarding the optimal application of SLNB.

Purpose of the Study:

  • To review recent advancements and developments in sentinel lymph node biopsy for breast cancer.
  • To address ongoing questions and highlight new evidence in SLNB application.

Main Methods:

  • Review of recent clinical trials and evidence.
  • Analysis of alternative injection techniques and imaging modalities.
  • Evaluation of SLNB in specific clinical scenarios like neoadjuvant chemotherapy and ductal carcinoma in situ.

Main Results:

  • Subareolar injection is a viable alternative to peritumoral injection, offering accuracy and convenience.
  • Lymphoscintigraphy may not be essential in all SLNB procedures.
  • Ongoing investigations focus on the significance of isolated tumor cells detected by immunohistochemistry and the necessity of axillary dissection following a positive SLNB.

Conclusions:

  • SLNB is established for stage I and II breast cancer.
  • Its use in stage III cancer, neoadjuvant therapy, and ductal carcinoma in situ remains investigational.
  • Informed consent must include discussion of relevant SLNB issues for patient awareness.
