Background: Vacuum-assisted biopsy (VAB) and core needle biopsy (CNB) are both widely used methods in diagnosing breast lesions. We aimed to determine whether the Elite 10-gauge VAB achieves higher accuracy than the BARD spring-actuated 14-gauge CNB.
Materials And Methods: This was a phase 3, open-label, parallel, randomized controlled trial (NCT04612439).
Background: The rate of carcinoma upgrade for atypical ductal hyperplasia (ADH) diagnosed on core needle biopsy (CNB) is variable on open excision. The purpose of the present study was to develop and validate a simple-to-use nomogram for predicting the upgrade of ADH diagnosed with ultrasound (US)-guided core needle biopsy in patients with US-detected breast lesions.
Methods: Two retrospective sets, the training set ( = 401) and the validation set ( = 186), from Fudan University Shanghai Cancer Center between January 2014 and December 2019 were retrospectively analyzed.
Background: Vacuum-assisted breast biopsy (VABB) has been routinely recommended for stereotactic intervention in cases of isolate mammographically-detected calcifications. Herein we aimed to evaluate and compare the diagnostic consistency and accuracy of calcified and noncalcified specimens obtained from same sites of sampling on mammography-visible calcifications. In addition, we presented the biopsy procedure and retrospectively evaluated the usefulness of VABB as well as the complications of this technique over an eight-year experience in our centre.

We aimed to predict the response to neoadjuvant chemotherapy using a second breast core needle biopsy after a median of 2 cycles of neoadjuvant chemotherapy.
Methods: We evaluated 805 consecutive patients undergoing neoadjuvant chemotherapy who had a second core needle biopsy between 2013 and 2017.
Background: For breast cancer patients, a false-negative rate lower than 10% can be achieved if targeted axillary dissection (TAD) is performed, which includes the excision of both biopsy-proven positive lymph nodes (BxLNs) and sentinel lymph nodes (SLNs). However, little evidence exists on the accuracy of intraoperative touch imprint cytology (ITPC) applied in TAD after neoadjuvant chemotherapy (NAC) for breast cancer patients with initial axillary metastasis. This study aimed to investigate the accuracy of ITPC in TAD after NAC.

To estimate the changing diagnostic patterns of breast cancer in urban Shanghai, 11,947 women with breast lesions detected by preoperative needle biopsy between January 1995 and December 2012 were selected from the Shanghai Cancer Data base, which integrates information from approximately 50% of breast cancer patients in Shanghai. The CNB procedure uses an automated prone unit, biopsy gun, and 14-gauge needles under freehand or ultrasound guidance and was performed by experienced radiologists and surgeons specializing in needle biopsies.

The novel single nucleotide polymorphism (SNP), rs2046210, was identified in a breast cancer genome-wide association study of Chinese women. The SNP is located on 6q25.1 in proximity to the C6orf97 and estrogen receptor 1 (ESR1) genes.
