False-negative core biopsy of the breast.

Stereotactic Core Biopsy of the Breast.

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...

False-negative results of breast core needle biopsies – retrospective analysis of 988 biopsies

BACKGROUND Breast cancer is the most common malignant neoplasm and the most common cause of death among women. The core needle biopsy is becoming a universal practice in diagnosing breast lesions suspected of malignancy. Unfortunately, breast core needle biopsies also bear the risk of having false-negative results. MATERIAL/METHODS 988 core needle breast biopsies were performed at the Maria S...

Mitochondrial genome deletion aids in the identification of false- and true-negative prostate needle core biopsy specimens.

We report the usefulness of a 3.4-kb mitochondrial genome deletion (3.4 mtdelta) for molecular definition of benign, malignant, and proximal to malignant (PTM) prostate needle biopsy specimens. The 3.4 mtdelta was identified through long-extension polymerase chain reaction (PCR) analysis of frozen prostate cancer samples. A quantitative PCR assay was developed to measure the levels of the 3.4 m...
