Summary
The sentinel lymph node (SN) biopsy accurately identifies breast cancer spread in most cases. However, further validation is needed before fully replacing axillary dissection in treatment.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Sentinel lymph node (SN) biopsy is a minimally invasive technique for staging breast cancer.
- Accurate staging is crucial for determining appropriate treatment and prognosis.
Purpose of the Study:
- To evaluate the feasibility and accuracy of the sentinel lymph node (SN) biopsy method in breast cancer treatment.
- To assess the diagnostic performance of SN identification and histological examination.
Main Methods:
- Prospective study of 21 breast cancer patients from December 1998 to December 1999.
- SN localization using scintigraphy and intraoperative detection.
- Histological examination of identified SN and axillary lymph nodes.
Main Results:
- Successful SN localization in 95% of cases via scintigraphy.
- Intraoperative SN identification in 90.5% of cases.
- High accuracy (95%) in detecting axillary lymph node metastasis via SN biopsy, with one false negative.
Conclusions:
- Sentinel lymph node biopsy demonstrates high accuracy in staging breast cancer.
- Despite promising results, complete axillary dissection was performed due to ongoing validation of the SN method.
- Further research is warranted to fully establish the SN method's role in breast cancer management.
