Summary
Sentinel lymph node dissection (SLND) accurately assesses breast cancer spread to axillary nodes. This minimally invasive technique is highly accurate and may replace complete lymph node dissection for early-stage breast cancer management.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Regional lymph node status is critical for breast cancer prognosis and treatment decisions.
- Accurate histopathologic assessment of axillary nodes is essential for staging early-stage breast cancer.
Purpose of the Study:
- To review the current status, controversies, and future directions of sentinel lymph node dissection (SLND) in breast cancer staging.
- To highlight the accuracy and minimal morbidity of SLND as a diagnostic technique.
Main Methods:
- Intraoperative lymphatic mapping using vital blue dye and/or radiocolloid to identify the sentinel lymph node.
- Focused histopathologic assessment of the sentinel node to determine axillary basin tumor status.
Main Results:
- SLND can be successfully performed in over 90% of eligible early-stage breast cancer patients.
- Sentinel node status accurately predicts the status of all axillary nodes in over 95% of cases.
- SLND demonstrates minimal morbidity and high accuracy, validated by multiple studies.
Conclusions:
- SLND is a highly accurate and minimally invasive staging technique for early-stage breast cancer.
- The data suggest SLND may replace complete lymph node dissection as the preferred axillary procedure.
- Continued research and validation are important for the future of SLND in breast cancer management.
