Background and study aims The optimal approach to small subepithelial tumors (SETs) of the upper gastrointestinal tract remains inconclusive. The aim of this study was to evaluate endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) for less invasive tissue sampling of small SETs of the upper gastrointestinal tract. Patients and methods In this prospective observational study patients with...

BACKGROUND AND AIMS In the following study case, we reviewed breast ultrasound-guided core needle biopsy (CNB), using Mammotome (vacuum-assisted breast biopsy) and Tru-cut, carried out on palpable and nonpalpable uncertain breast lumps or malignant large lesions to be submitted to neoadjuvant chemotherapy. MATERIAL AND METHODS Examinations were conducted during a 4-year period of clinical act...

PURPOSE To investigate whether the use of a disposable needle guide results in a decreased incidence of infectious complication after transrectal prostate needle biopsy (TPNB). MATERIALS AND METHODS Fifty five patients who underwent 10-core TPNB were randomized into two groups. A pre-biopsy blood and urine examination was performed in both groups. Group 1 (25 patients) underwent biopsy with d...

background in surgical pathology, atypical small acinar proliferation is commonly detected in prostate biopsies. most studies on atypical small acinar proliferation have examined morphological characteristics and the utility of immunohistochemical studies.however, these resources are not available to many pathology departments. we have found that examining additional sections is a simple and in...

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...

Retraction notice for the article that appeared on page 128 of the January 2015 issue of the Pancreas journal. The randomized trial involved 72 patients between two participating centers. The published article includes 100 patients. The authors added 28 patients to show statistically that there was no difference in the main outcomes measures despite changing the sample size to 100 patients. The...

Recent reports suggest that the finding of lobular neoplasia (atypical lobular hyperplasia [ALH] or lobular carcinoma in situ [LCIS]) in breast core needle biopsy specimens may be associated with an increased risk of both ductal carcinoma in situ (DCIS) or invasive carcinoma at excision. We reviewed our breast core biopsy material to see if we could confirm this finding. From 4,297 biopsies, 71...

BACKGROUND Breast screening is a method of detecting breast cancer at a very early stage. Most of the lesions detected by screening are not malignant. Objective of this study was to compare ultrasound guided fine needle aspiration cytology and core biopsy in the preoperative assessment of non-palpable breast lesions. METHODS The study was conducted prospectively at Department of Radiology, Sh...

The immunohistochemical expression of Programmed Death Ligand (PD-L1) predicts responses to PD-1/PD-L1 inhibitors in non-small cell lung cancer (NSCLC). PD-L1 testing is currently only recommended on tissue specimens; however, in many patients, cytology samples are the only specimens available. The introduction of the novel 19G "core-biopsy" needle has revolutionized the utility of endobronchia...
