Results
Axillary preoperative ultrasound were performed in 190 patients who had indication of Sentinel Lymph Node Biopsy
- A total of 118 patients had the axillary ultrasound normal. After SLNB 99 were diagnosed accurately (true negative), and the other 19 had metastases (false negative); 12/19 micrometastases (<3mm) and 7/19 macrometastases
- Of the 43 asimetric cortical thickening, 29 had metastases proven by axillary lymphadenectomy or ultrasound CNB (true positive). 14/43 had no metastases at surgery (SLNB) (false positive)
- All of the 29 suspicious axillary lymph nodes were proved by ultrasound CNB or axilar lymphadenectomy (true positive)
Correlation Axillary Ultrasound - Surgery (SLNB or AL)
- Sensibility 75%
- Specificity 88%
- PPV 81%
- NPV 84%
Correlation Axillary Core Needle Biopsy- Surgery (SLNB or AL):
- 56 Core Needle Biopsy: 41/56 were positive and 15/56 were negative. Of the 15 negative Core Needle Biopsies, 11 had no metastases (true negative) and 4 had metastases (false negative)
- Sensibility 93,2%
- Specificity 100%
- PPV 100 %
- NPV 73,3%
