Summary
Sentinel lymph node (SLN) biopsy for breast cancer is feasible under local anesthesia (LA), offering efficient outpatient diagnosis with high detection rates comparable to general anesthesia (GA). This approach minimizes patient discomfort and optimizes resource utilization.
Area of Science:
- Oncology
- Surgical Pathology
- Anesthesiology
Background:
- Sentinel lymph node (SLN) biopsy in breast cancer patients can be performed under local anesthesia (LA).
- LA offers potential advantages including efficient operating room and pathologist time utilization.
- Histologic diagnosis is provided before definitive breast surgery.
Purpose of the Study:
- To assess the feasibility of SLN biopsy under LA.
- To compare SLN procedures performed under LA versus general anesthesia (GA).
Main Methods:
- SLN procedures were performed on 50 outpatients under LA and 167 inpatients under GA.
- The study compared SLN detection rates and the number of mapped/harvested SLNs between the two groups.
- The duration of SLN biopsies under LA was measured.
Main Results:
- A median of 2 SLNs were harvested per patient in both LA and GA groups.
- The SLN detection rate was 1.00 for the LA group and 0.99 for the GA group.
- A non-significant decrease in procedure duration was observed over consecutive months for the LA group.
Conclusions:
- SLN biopsy can be safely and effectively performed under LA for breast cancer patients.
- LA allows for early lymph node status diagnosis on an outpatient basis with minimal patient discomfort.
- Experienced surgeons can master the LA procedure efficiently, as indicated by the learning curve analysis.
