World Health Organization (WHO)/International Society of Urological Pathology (ISUP) grading in fine‐needle aspiration biopsies of renal masses [PDF]

, 2018
Background Utilization of fine‐needle aspiration (FNA) biopsy for the evaluation of renal masses has been increasing at our institution. At times diagnostic material on direct smears is superior to that in the cell block/core biopsy, therefore assigning

Fine-needle aspiration and core biopsy in the diagnosis of breast lesions: A comparison and review of the literature

CytoJournal, 2016
In recent times, the diagnosis of breast lesions has mostly become dependent on core needle biopsies (CNBs) with a gradual reduction in the rate of performing fine-needle aspiration cytology (FNAC).

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

Molecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

EUS-Guided Biopsy with a Novel Puncture Biopsy Forceps Needle—Feasibility Study

Diagnostics, 2021
Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) or biopsy (FNB) to diagnose lesions in the gastrointestinal tract is common. Demand for histology sampling to identify treatment-specific targets is increasing. Various core biopsy FNB needles

Ultrasonic Actuation of a Fine-Needle Improves Biopsy Yield [PDF]

arXiv, 2020
Despite the ubiquitous use over the past 150 years, the functions of the current medical needle are facilitated only by mechanical shear and cutting by the needle tip,i.e.the lancet. In this study, we demonstrate how nonlinear ultrasonics (NLU) extends the functionality of the medical needle far beyond its present capability. The NLU actions were found

Effectiveness of core needle biopsy in the diagnosis of thyroid lymphoma and anaplastic thyroid carcinoma: A systematic review and meta-analysis [PDF]

, 2022
Both anaplastic thyroid carcinoma (ATC) and thyroid lymphoma (TL) clinically present as rapidly enlarging neck masses. Unfortunately, in this situation, like in any other thyroid swelling, a routine fine-needle aspiration (FNA) cytology is the first and ...

Impact of touch preparations on core needle biopsies [PDF]

Cancer Cytopathology, 2014
BACKGROUNDTouch preparations (TPs) can be performed for on‐site adequacy assessment of core needle biopsies (CNBs). Although TPs can play a role in decreasing the number of nondiagnostic core biopsies, the impact of TPs on CNB has not been extensively evaluated.METHODSComputerized tomography–guided CNBs performed in a tertiary cancer center were ...

Best practices in surgical and nonsurgical management of head and neck Merkel cell carcinoma: An update

Molecular Carcinogenesis, Volume 62, Issue 1, Page 101-112, January 2023., 2023
Abstract Merkel cell carcinoma (MCC) is a rare, highly aggressive cutaneous neuroendocrine carcinoma. Controversy exists regarding optimal management of MCC as high‐quality randomized studies and clinical trials are limited, and physicians are bound to interpret highly heterogeneous, retrospective literature in their clinical practice. Furthermore, the

Prostate biopsies guided by three-dimensional real-time (4-D) transrectal ultrasonography on a phantom: comparative study versus two-dimensional transrectal ultrasound-guided biopsies [PDF]

European Urology 52, 4 (2007) 1097-104, 2007
OBJECTIVE: This study evaluated the accuracy in localisation and distribution of real-time three-dimensional (4-D) ultrasound-guided biopsies on a prostate phantom. METHODS: A prostate phantom was created. A three-dimensional real-time ultrasound system with a 5.9MHz probe was used, making it possible to see several reconstructed orthogonal viewing ...

Comparison of Thyroid Fine-Needle Aspiration and Core Needle Biopsy [PDF]

American Journal of Clinical Pathology, 2007
We compared the adequacy and accuracy of fineneedle aspiration (FNA) with core needle aspiration in a total of 377 patients who underwent both tests. The adequacy rate for core needle biopsy (82.2%) was significantly higher than that of FNA (70.3%; P < .001), but the combined adequacy was significantly higher than that for either test alone (88.9%; P <
