Coccidioidomycosis causes significant morbidity in endemic areas. In the absence of sensitive diagnostic serologic testing, clinicians have increasingly relied on lung and lymph node biopsies for diagnosis. Recently, endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) has been shown to be an excellent sampling method for the diagnosis and staging of lung cancers, especially when combined with endoscopic ultrasound guided fine needle aspiration (EUS-FNA). We present 13 consecutive cases where EBUS-TBNA and/or EUS-FNA of pulmonary lymph nodes were performed as part of the workup for pulmonary coccidioidomycosis...

Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been applied to pancreatic lesions since the 1990s, and its use is now widespread. Improvements in endoscopic devices and sampling techniques have resulted in excellent diagnostic ability for solid pancreatic lesions. However, clinical improvements alone are not responsible for it; pathological aspects have also played important roles. Rapid on-site evaluation minimizes endoscopic procedures, although its value at improving the diagnostic ratio is still debated...

BACKGROUND: Molecular tests have clinical utility for thyroid nodules with indeterminate fine-needle aspiration (FNA) cytology, although their performance requires further improvement. This study evaluated the analytical performance of the newly created ThyroSeq v3 test. METHODS: ThyroSeq v3 is a DNA- and RNA-based next-generation sequencing assay that analyzes 112 genes for a variety of genetic alterations, including point mutations, insertions/deletions, gene fusions, copy number alterations, and abnormal gene expression, and it uses a genomic classifier (GC) to separate malignant lesions from benign lesions...

Mixed adenoneuroendocrine carcinoma (MANEC) is defined as a tumor that has morphologically recognizable both adenocarcinoma and neuroendocrine carcinoma components comprising at least 30% of either components. MANEC occurring in the ampulla of Vater is extremely rare, and only 16 cases have been reported in the English language literature. In the present report, we describe the first case of MANEC of the ampulla of Vater with immunocytochemical analyses. An 82-year-old Japanese male was incidentally found to have a tumorous lesion in the ampulla of Vater...

The combined administration of nab-paclitaxel and gemcitabine (nab-P + Gem) is a standard chemotherapy for unresectable pancreatic ductal adenocarcinoma (UR-PDAC); thus, a predictive biomarker to identify patients best suited for nab-P + Gem therapy would be useful. Class III β-tubulin (TUBB3) has been reported to be a predictive marker for taxane resistance in various tumors. However, the correlation between TUBB3 expression and the response to nab-P + Gem in patients with UR-PDAC has not been evaluated. We retrospectively reviewed 75 patients with UR-PDAC who received nab-P + Gem...

BACKGROUND: Small tumor diagnostic tools including ultrasound-guided fine needle aspiration (FNA) and computed tomography (CT) could be causing rising and racially/ethnically different thyroid cancer incidence rates due to variable overdiagnosis of indolent tumors. Papillary tumors and <40 mm tumors are most likely to be overdiagnosed as indolent tumors by FNA and CT. METHODS: Age-adjusted incidence rates (AAIRs) for the years 2007-2014 were calculated for race/ethnicity (white, Hispanic, Asian, African American, Native American) by patient/tumor characteristics for microscopically confirmed malignant thyroid cancer cases in the Surveillance, Epidemiology, and End Results Program 18 database (SEER 18; N = 93,607)...

BACKGROUND AND AIMS: Pancreatic cancer organoids are tumor models of individualized human pancreatic ductal adenocarcinoma (PDA), created from surgical specimens and used for personalized treatment strategies. Unfortunately the vast majority of patients with PDA are not operative candidates. Creation of human PDA organoids at the time of initial tumor diagnosis is therefore critical. Our aim was to assess the feasibility of creating human PDA organoids by EUS fine-needle biopsy (EUS-FNB) in patients with PDA...

BACKGROUND: Deep enteroscopy-assisted ERCP (DEA-ERCP) in post-bariatric Roux-en-Y (RY) anatomy is challenging. Laparoscopy-assisted ERCP (LA-ERCP) or EUS-directed transgastric ERCP (EDGE) are technically easier and faster, but are more invasive and morbid procedures. Therefore, we have used DEA-ERCP as our first-line approach, reserving EDGE and LA-ERCP for cases in which adjunctive techniques that cannot be performed through an enteroscope are required (eg, EUS-FNA, SO manometry), or DEA-ERCP failures...

BACKGROUND: Twenty-seven percent of neuroendocrine tumors (NETs) are associated with distant metastases, and in some patients, the primary site is unknown. Orthopedia homeobox protein (OTP) has been described as a useful marker for lung carcinoids (LCs) and for separating low-grade typical carcinoids (TCs) from intermediate-grade atypical carcinoids (ACs) in resection specimens. This study evaluated OTP, thyroid transcription factor 1 (TTF-1), and Ki-67 expression in fine-needle aspiration (FNA) samples of various NETs...

The effectiveness of the Free Nitrous Acid (FNA) sludge treatment was tested in the range from 0 to 3.0 mg N-HNO2/L with acidified and neutral pH. 4 h pre-treatment times were used and the specific methane production (SMP) investigated. Results show that between 50 and 100 mg/L of N-NO2-/L disappeared during the FNA pre-treatment, reducing its effectiveness. A minimum level of nitrite (174 mg N-NO2-/L tested in this study), independently of pH/FNA, was necessary to assure the presence of the chemical throughout the duration of the pre-treatment...
