Abstract:
Objective:To compare the clinical value of digital breast tomosynthesis (DBT) localization and stereotactic positioning biopsy of breast lesions.Methods:This study was a cross-sectional study. Totally of 250 patients who underwent breast biopsy at Shenzhen People′s Hospital, Luohu District People′s Hospital and Peking University Shenzhen Hospital between August 2021 to October 2023 was analyzed retrospectively, including 136 cases of DBT-guided biopsy (DBT-guided group) and 114 cases of stereotactic-guided biopsy (stereotactic-guided group). The stereotactic-guided biopsy methods included core needle biopsy (CNB) and wire positioning. The DBT-guided biopsy methods included CNB, wire positioning and vacuum-assisted breast biopsy (VABB). The χ2 test or Mann-Whitney U test was used to compare the puncture success rate, operation time, localization time, puncture time, number of first valid localization phases obtained, number of exposures, and complications of different biopsy methods between 2 groups. Results:In the wire positioning biopy, the puncture success rate was 100% (33/33) in DBT-guided group and 96% (48/50) in the stereotactic-guided group, with no statistically significant difference between the two groups ( P=0.515). Compared to the stereotactic-guided group, the operation time and localization time were shorter, and the number of first valid localization phases obtained, number of exposures were fewer in the DBT-guided group( P<0.05). The incidence of complications was lower in both the DBT-guided group and the stereotactic-guided group, with no statistically significant difference ( P=0.871). In CNB, both the DBT-guided group and the stereotactic-guided group had higher puncture success rates, with no statistically significant difference ( P=0.080). Compared to the stereotactic-guided group, the operation time, localization time and puncture time were shorter, and the number of first valid localization phases obtained, number of exposures were lower in the DBT-guided group, and the difference between the two groups were statistically significant ( P<0.05). The incidence of complications was lower in both the DBT-guided group and the stereotactic-guided group, with no statistically significant difference ( P=0.627). Twenty-one cases received DBT-guided VABB, with an operation time of (19.90±3.38) min, a localization time of 6.00 (6.00, 7.00) min, a puncture time of (13.42±3.28) min, the number of first effective localization phases obtained was 1.00 (1.00, 1.00) time, the number of exposures was 4.00 (3.50, 5.00) times, and one case experienced severe pain after puncture. Conclusion:Compared with stereotactic-guided biopsy, DBT-guided biopsy can reduce operation time and exposure times, and can target more types of breast lesions, with higher clinical application value.
