Summary
Endoscopic sentinel node biopsy using axilloscopy is a feasible technique for breast cancer staging. This minimally invasive approach aids in visualizing the axilla and accurately resecting sentinel nodes, potentially reducing complications.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Sentinel node biopsy (SNB) is crucial for accurate breast cancer axillary staging.
- Reducing false negatives and morbidity in SNB remains a significant challenge.
- New techniques are needed for effective axillary clearing in complex cases.
Purpose of the Study:
- To evaluate the feasibility of axilloscopy and endoscopic sentinel node biopsy.
- To assess the utility of endoscopic techniques for axillary space visualization and SNB.
Main Methods:
- Endoscopic axillary sentinel node biopsy was performed in 35 breast cancer patients.
- Procedures followed blue dye-guided lymphography and axillary fat liposuction.
- Evaluated anatomical landmark exposure, SN detection rate, false negative rate, and axillary clearing accuracy.
Main Results:
- Excellent anatomical orientation was achieved in most cases.
- The sentinel node detection rate was 83.3%.
- One case showed the sentinel node did not represent the entire axillary status; 17.1 lymph nodes were removed in subsequent clearing.
Conclusions:
- Axilloscopy combined with endoscopic SNB is a feasible, accurate, and minimally invasive procedure.
- The endoscopic approach enhances axillary space visualization, potentially mitigating SNB pitfalls.
- This technique may evolve into a minimally invasive option for complete axillary lymphadenectomy when necessary.
