Impact of molecular testing on detecting mimics of oncocytic neoplasms in thyroid fine-needle aspirates diagnosed as follicular neoplasm of Hürthle cell (oncocytic) type.

Cancer Cytopathol 2021 Apr 26. Epub 2021 Apr 26.

Department of Pathology, University of Pittsburgh Medical Center (UPMC), Pittsburgh, Pennsylvania.

Background: Some thyroid nodules cytologically presenting as follicular neoplasm, Hürthle cell (Oncocytic) type (FNHCT), are not oncocytic tumors and represent autonomously functioning thyroid nodules (AFTNs) with TSHR, GNAS, and EZH1 mutations or oncocytic metaplasia. A to be defined subset of FNHCT harbors genome haploidisation-type DNA copy number alterations (GH-CNA). Molecular profiling of FNHCT may distinguish oncocytic neoplasms from its mimics. Read More

Characterization and clinical significance of the CADM1/HER2/STAT3 axis in serous ovarian tumors.

Medicine (Baltimore) 2021 Feb;100(8):e23777

Department of Obstetrics and Gynecology, the Second Affiliated Hospital of University of South China, Hunan.

Abstract: The subtypes of serous ovarian tumors (SOTs), including benign serous cystadenoma, serous borderline tumor (SBT), low-grade serous ovarian carcinoma (LGSC), and high-grade serous ovarian carcinoma (HGSC), remain poorly understood.

The feasibility of anterior 180° Tc-sestamibi parathyroid SPECT/CT.

Ann Nucl Med 2021 Feb 3;35(2):203-210. Epub 2021 Jan 3.

Department of Nuclear Medicine, Kaohsiung Chang Gung Memorial Hospital, Chang Gung University College of Medicine, No. 123, Dapi Rd., Niaosong Dist., Kaohsiung, 833, Taiwan, ROC.

Intern Med J 2020 Dec 6. Epub 2020 Dec 6.

Gastroenterology Department, Tauranga Hospital, Bay of Plenty, District Health Board, Tauranga, New Zealand.

Background: Surveillance colonoscopy has been shown to be an effective tool for prevention of CRC in high-risk populations, if adhered to. We aimed to discover the sequelae of late surveillance in a cohort of patient's overdue for colonoscopy, in particular the development of colorectal cancer (CRC) or advanced adenoma (AA) within surveillance subgroups.

Method: We conducted a retrospective cohort study on all patients from the Bay of Plenty District Health Board region, New Zealand, placed on the colonoscopy surveillance waitlist from 2006 onwards who had their procedure completed between 1 November 2016 and 31 January 2018, when the total surveillance list was declared up-to-date.

Utility and Limitations of Albumin mRNA In Situ Hybridization Detection in the Diagnosis of Hepatobiliary Lesions and Metastatic Carcinoma to the Liver.

Appl Immunohistochem Mol Morphol 2021 03;29(3):180-187

Department of Pathology and Laboratory Medicine, Hartford Hospital, Hartford, CT.

Albumin messenger RNA (mRNA) in situ hybridization is a sensitive and specific biomarker for hepatocellular carcinoma (HCC). Intrahepatic cholangiocarcinoma (ICC) shows variable sensitivity, whereas extrahepatic cholangiocarcinoma (ECC) and metastatic carcinoma are generally negative. We studied the clinical utility and limitations of albumin mRNA detection in a cohort of HCCs, ICCs, ECCs, bile duct adenomas, bile duct hamartomas, and metastatic carcinomas to the liver; and investigated the variability in sensitivity observed for this biomarker in ICCs.

Colonoscopy later than 270 days in a fecal immunochemical test-based population screening program is associated with higher prevalence of colorectal cancer.

Endoscopy 2020 10 30;52(10):871-876. Epub 2020 Apr 30.

Veneto Tumour Registry, Azienda Zero, Padova, Italy.

BACKGROUND : Colorectal cancer (CRC) screening programs based on fecal immunochemical testing (FIT) generate substantial pressure on colonoscopy capacity in Europe. Thus, a relevant proportion of FIT-positive patients undergo colonoscopy after the recommended 30-day interval, which may be associated with an excess CRC risk. METHODS : In a cohort of 50-69-year-old patients undergoing biennial rounds of FIT (OC-Hemodia latex agglutination test; cutoff 20 µg hemoglobin/g feces) between 2004 and 2017, we assessed the outcome at colonoscopy (low/high risk adenoma/CRC/advanced stage CRC) among FIT-positive patients, according to different time intervals.
