Summary
Sentinel node (SN) biopsy in breast cancer helps determine the need for axillary lymph node dissection. SN examination can individualize treatment, but accuracy depends on tumor size and histological analysis.
Area of Science:
- Oncology
- Surgical Pathology
- Diagnostic Imaging
Background:
- Axillary lymph node status is crucial for breast cancer prognosis and adjuvant treatment decisions.
- Sentinel node (SN) biopsy aims to individualize axillary staging and optimize lymph node diagnosis.
Purpose of the Study:
- To evaluate the role of sentinel node (SN) examination in individualizing axillary lymph node resection for breast cancer.
- To assess the accuracy of SN biopsy in diagnosing lymph node metastasis.
Main Methods:
- 96 breast cancer patients underwent preoperative lymph-drainage scintigraphy and intraoperative probe detection for SN identification.
- SNs were removed and compared histologically with all other axillary lymph nodes (levels I and II).
Main Results:
- In 77 identified SNs, metastasis was found exclusively in the SN in 9 cases, and in both SN and other nodes in 18 cases.
- SNs were tumor-free in 44 patients; however, in 6 cases, the SN was not representative of axillary metastasis.
- SN representativeness was linked to tumor size: less reliable for T3/T4 tumors compared to T1/T2 tumors.
Conclusions:
- Sentinel node (SN) resection allows for individualized axillary lymph node management in breast cancer primary treatment.
- Enhanced histological examination, including serial sections and immunohistochemistry, may improve diagnostic accuracy.
