Abstract
Background
Core needle biopsy (CNB) and vacuum-assisted biopsy (VAB) are both popularly used breast percutaneous biopsies. Both of them have become reliable alternatives to open surgical biopsy (OSB) for breast microcalcification (BM).
Aims
It is controversial that which biopsy method is more accurate and safer for BM. Hence, we conducted this meta-analysis to compare the diagnostic performance between CNB and VAB for BM, aiming to find out the better method.
Methods
Articles according with including and excluding criteria were collected from the databases, PubMed, Embase, and the Cochrane Library. Preset outcomes were abstracted and pooled to find out the potential advantages in CNB or VAB.
Results
Seven studies were identified and entered final meta-analysis from initially found 138 studies. The rate of ductal carcinoma in situ (DCIS) underestimation was significantly lower in VAB than CNB group [risk ratio (RR) = 1.83, 95% confidence interval (CI) 1.40 to 2.40, p < 0.001]. The microcalcification retrieval rate was significantly higher in VAB than CNB group (RR = 0.89, 95% CI 0.81 to 0.98, p = 0.02), while CNB owned a significantly lower complication rate than VAB (RR = 0.18, 95% CI 0.03 to 0.93, p = 0.04). The atypical ductal hyperplasia (ADH) underestimation rates were not compared for the limited number of studies reporting this outcome.
Conclusions
Compared with CNB, VAB shows better diagnostic performance in DCIS underestimation rate and microcalcification retrieval rate. However, CNB shows a significantly lower complication rate. More studies are needed to verify these findings.
