Purpose: Recently, results of many trials that intend to decide the axillary status
through more conservative procedures are reported. One of these is sentinel node biopsy.
This method is regarded as reasonable and selective. Some investigators tend to omit
axillary dissection in the patient who is determined to have negative node clinically and
negative result in sentinel node biopsy procedure. This study was designed to know
how accurate the sentinel node biopsy method can predict axillary nodal status.
Materials and Method : The patients group was selected from Department of Surgery at
SMC, consisting of 111 patients with surgically curable breast cancer from Sept. 1995 to
Apr 1997 Isosulfan blue was injected in the center of mass and the margins of 4
quadrant under the general anesthesia. Axillary dissection was done 5 minutes after
injection to identify the stained lymphatics. When stained lymphatics were identified,
dissection was performed along the lymphatics bidirectionally to detect the stained lymph
node nearest to the primary tumor (sentinel node). After frozen biopsy of sentinel node,
routine axillary node dissection was performed. Results of frozen biopsy were compared
with the final pathologic results.
Results : Sentinel node was detected in 80 of the 111 cases (72.1%) and there were 44
(55.0%) axillary metastasis cases in sentinel node detection group. In 14 of 44 cases,
sentinel node was only positive. In 5 of 41, sentinel node were falsely negative for
malignancy. Negative predictive value of the method is 87.8% (36/41).
Conclusion : Sentinel node biopsy method can predict the axillary nodal status in
patients with breast cancer. This method can lead to more conservative treatment,
eventually omitting axillary nodal dissection in selected patients.
