Examining the sensitivity of ultrasound‐guided large core biopsy for invasive breast carcinoma in a population screening programme

Abstract

We demonstrated a sensitivity of 96.5% with a mean of 2.21 cores. False-negative results were more likely in the absence of post-fire needle position verification and with tubular carcinomas. Neither tumour size nor core number predicted diagnostic accuracy.

Effectiveness of core biopsy for screen‐detected breast lesions under 10 mm: implications for surgical management

“…The overall false‐negative rate of 2.6% and non‐representative/lesion miss rate of 3.1% are both within the range of 2–5% rates reported previously . In the context of these rather small lesions, it is reassuring that the miss rate is not significantly higher.…”
