Abstract

Objectives: To evaluate the value of ultrasound-guided core needle biopsy in diagnosing breast cancer histology in comparison with postoperative results. Subjects and Methods: A retrospective study was conducted at the National Cancer Hospital from June 2021 to June 2022, on 55 breast cancer patients diagnosed by ultrasound-guided core needle biopsy and operated on. Describe the characteristics of lesions on ultrasound, mammography, and factors in the biopsy process. Histological diagnosis on biopsy - operative tissue and related factors were analyzed. Results: The mean tumor size was 21.9mm. Ductal carcinoma was the most common histological type, accounting for 76.4%. The accuracy of histological diagnosis on ultrasound-guided core needle biopsy tissue was 74.5%. In the diagnosis of invasive breast cancer, core needle biopsy showed sensitivity, specificity, and accuracy of 87%, 100%, and 87.3%, respectively. The positive predictive value and the negative predictive value were 100% and 12.5%. Conclusion: Ultrasound-guided core needle biopsy is a valuable method in histological diagnosis, as well as the diagnosis of invasive breast cancer. However, in the diagnosis of breast cancer in situ, core needle biopsy still has many limitations, requiring an increase in sample size or the number of specimens to improve diagnostic capacity.
