| aspiration biopsy (FNAB) for the diagnosis of metastasis in the axillary lymph node
(LN) of patients with breast cancer.
Materials and Methods: A retrospective review of the data was performed on 327
breast cancer patients that underwent axillary US from Jun 2006 to July 2008. USguided
FNAB was performed when a LN indicated suspicious findings. Results of
FNAB were compared with those of subsequent surgery.
Results: Of the 327 patients, 111 showed suspicious findings on US and underwent
FNAB. Among the 111 cases, 73 (66%) were positive for cancer, while 38 (34%)
were negative results. A Total of 254 patients who had normal findings on US
(n=216) and negative results on FNAB (n=38) underwent SNB, of which 56 (22%)
were proven to have metastasis. Sensitivity and specificity of US were 61.9% and
81.8%, respectively, with a positive predictive value (PPV) of 65.8% and negative predictive
value (NPV) of 79.2%. Sensitivity and specificity of US-guided FNAB were
86.9% and 100%, respectively, with a PPV of 100% and a NPV of 71.7%.
Conclusion: US and US-guided FNAB performed for axillary staging are useful
methods with a high specificity and positive predictive value in invasive breast cancer
