Summary
Sentinel lymph node biopsy (SNB) is increasingly used in breast cancer management, even in cases previously deemed unsuitable. Further research is needed to clarify the prognostic impact of micrometastases and isolated tumor cells identified through SNB.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Clinical management of breast cancer has significantly advanced over the past 20 years.
- Sentinel lymph node biopsy (SNB) enables axillary lymph node preservation in most breast cancer patients.
- SNB facilitates the detection of occult nodal disease and detailed staging through step sectioning.
Purpose of the Study:
- To review the expanding indications for SNB in breast cancer.
- To highlight the evolving role of SNB in complex cases.
- To identify areas requiring further investigation in breast cancer staging.
Main Methods:
- Review of accumulating evidence supporting SNB in previously contraindicated cases.
- Analysis of the role of step sectioning in identifying nodal disease.
- Identification of research gaps in prognostic significance of micrometastases.
Main Results:
- Evidence supports the use of SNB in large tumors, multicentric disease, recurrent cancers, and after neoadjuvant therapy.
- SNB provides more detailed staging information compared to traditional methods.
- Current evidence suggests SNB is feasible and beneficial across a wider range of breast cancer scenarios.
Conclusions:
- SNB is becoming a standard procedure for staging breast cancer, with expanding indications.
- Further prospective, randomized trials are essential to clarify the prognostic significance of micrometastases and isolated tumor cells.
- The role of SNB in optimizing breast cancer treatment and staging continues to evolve.
