Underestimation of invasive malignancy on conventional core biopsy of breast

[Underestimation of malignancy of core needle biopsy for nonpalpable breast lesions].

PURPOSE To determine the rate of underestimation of an image-guided core biopsy of nonpalpable breast lesions, with validation by histologic examination after surgical excision. METHODS We retrospectively reviewed 352 biopsies from patients who were submitted to surgery from February 2000 to December 2005, and whose histopathologic findings were recorded in the database system. Results were c...

Underestimation of atypical ductal hyperplasia at sonographically guided core biopsy of the breast.

OBJECTIVE The purpose of this study was to determine the rate of underestimation of atypical ductal hyperplasia (ADH) at sonographically guided core biopsy of the breast and to identify the factors involved. MATERIALS AND METHODS We retrospectively reviewed 3,563 lesions con secutively evaluated with sonographically guided core biopsy between January 2002 and June 2006. Histologic analysis yi...

Breast cancer underestimation rate of atypical ductal hyperplasia diagnosed by core-needle biopsy under imaging guidance.

OBJECTIVE To evaluate breast cancer underestimation rate of atypical ductal hyperplasia (ADH) diagnosed by core-needle biopsy (CNB) under imaging guidance in Ramathibodi Hospital and to determine the difference between the malignant and benign groups in terms of clinical and imaging characteristics. MATERIAL AND METHOD The pathological records of 1521 patients who underwent CNB under imaging ...

Concordance Rate between Fine Needle Aspiration Biopsy and Core Needle Biopsy in Breast Lesions

Background and Objectives:Breast cancer is the most common cancer among women worldwide. Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast le...
