Efficacy of ultrasound-guided vacuum-assisted biopsy in the diagnosis of several breast tumors

Abstract

Background: Vacuum-assisted breast biopsy (VABB) has now been used more and more widely to obtain an early diagnosis of breast cancer and exact results for other lesions in the breast.

Objective: This study aims to evaluate the efficacy of ultrasoundguided vacuum-assisted biopsy in the diagnosis of several breast diseases.

Methods: A cross-sectional descriptive study was conducted on 108 women (mean age 41,6) with 188 breast lesions classified as BIRADS 3 or higher and were taken by VABB at Tam Anh Hanoi General Hospital from February 2022 to March 2023.

Results: The mean largest size was 12,6mm. The lesions classified as BIRADS 3 account for 52,6%, while the remainder are classified as BIRADS 4 or higher. 20,7% of lesions were applied markers after being removed. Histopathological results after VABB showed 3 carcinomas which were 100% compatible with the subsequent surgical results, while the rest were benign fibroadenomas and benign fibrocystic changes. The average cutting time for each tumor was 9,7 minutes, and the average anesthetic dose per lesion was 1,8 ml. Following the biopsy of the entire lesion, the hematoma was found to be 14,1mm and 4,6mm in width and thickness respectively. The mean post-procedural pain score was 1,2, which was well controlled by conventional NSAIDs without any further intervention. Conclusion: VABB is a safe, simple and effective method to figure out breast histopathologic results with 100% accuracy.
