Özet
Aim: The aim of this study was to assess the efficacy of preoperative axillary ultrasonography (AUS) and preoperative axillary fine-needle aspiration biopsy (FNAB) from suspicious lymph nodes in clinically node-negative breast cancer to compare with radiologically positive and sentinel lymph node biopsy (SLNB) positive involvement. Method: Clinically node-negative early-stage breast cancer patients were included in the study. These patients underwent preoperative AUS examination, suspicious lymph nodes were evaluated with FNAB. AUS-FNAB results were compared with those of SLNB or axillary dissection. Results: Of 181 patients undergoing AUS, 32 were reported to have axillary metastasis, 25 suspicious, and 124 benign nodes. The suspicious group underwent FNAB examination and metastasis was found in 9 of them. The sensitivity of AUS-FNAB was found to be 64.06%, specificity 100%, positive predictive value 100%, and negative predictive value (NPV) 83.5%. The false negativity rate (FN) of this method was 16,4%. Lymphovascular invasion and tumour size were found statistically significant factors for false negativity. Conclusion: It was concluded that axillary AUS-FNAB with its high NPV, low FN rate, may be a clinical alternative to SLNB for early-stage breast cancer patients.
