Increased thyroid malignancy in patients with primary hyperparathyroidism.

Endocr Connect 2021 Jul 1. Epub 2021 Jul 1.

L Sheng, Department of Thyroid Surgery, Shandong University Qilu Hospital, Jinan, China.

Background: Multiple studies have reported increased incidence of thyroid cancer in patients with primary hyperparathyroidism (PHPT). However, the underlying risk factors of concomitant thyroid cancer in patients with PHPT remain unknown. The primary aim of this study was to examine the records of patients with PHPT to identify characteristics that correlated with the presence of coexisting thyroid nodules, and which may have an implication for the prediction of thyroid cancer.

Diagnostic Value of Galectin-3 in Distinguishing Invasive Encapsulated Carcinoma from Noninvasive Follicular Thyroid Neoplasms with Papillary-Like Nuclear Features (NIFTP).

Cancers (Basel) 2021 Jun 15;13(12). Epub 2021 Jun 15.

Alex and Simona Shnaider Research Laboratory in Molecular Oncology, Lunenfeld-Tanenbaum Research Institute, Sinai Health System, Mount Sinai Hospital, Toronto, ON M5G 1X5, Canada.

: non-invasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTP), which is considered as low-risk cancer, should be distinguished from the malignant invasive encapsulated follicular variant of papillary thyroid carcinoma (EFVPTC). Improved discrimination of NIFTPs from invasive EFVPTCs using a molecular biomarker test could provide useful insights into pre- and post-surgical management of the indeterminate thyroid nodule. Galectin-3 (Gal-3), a β-galactosyl-binding molecule in the lectin group, is involved in different biological functions in well differentiated thyroid carcinomas. Read More

INSM1 Expression in Breast Neoplasms with Neuroedocrine Features.

Endocr Pathol 2021 May 19. Epub 2021 May 19.

Department of Oncology, Pathology Unit, University of Turin, Via Santena 7, 10126, Turin, Italy.

According to the 2019 WHO classification of breast tumors, neuroendocrine neoplasms (NENs) are classified into well-differentiated NE tumors (NET) and poorly differentiated NE carcinomas (NEC), while other breast cancers (BCs) of special and no special type with neuroendocrine (NE) features are not incorporated in this scheme anymore. We aimed to assess whether INSM1, a novel NE marker, could have a role in breast NEN subtyping. We selected 63 BCs operated from 2003 to 2018, classified as BCs with NE features, with available clinico-pathological data. Read More

BMC Gastroenterol 2021 May 18;21(1):224. Epub 2021 May 18.

Department of Gastroenterology and Hepatology, Nagoya University Graduate School of Medicine, Nagoya, 4668550, Japan.

Background: Endoscopic papillectomy of duodenal papillary tumors (PT) is indicated for adenomas or well-differentiated adenocarcinomas that do not involve the sphincter of Oddi. However, there is currently no reliable pre-operative method to diagnose the infiltration in the sphincter of Oddi.' Insulin-like growth factor 2 mRNA protein 3 (IMP3) staining is reportedly associated with advanced disease stage and clinical outcomes in many carcinomas. Read More

Well-differentiated papillary mesothelioma is an uncommon benign, although potentially recurrent mesothelial lesion that occurs in the peritoneum of women over a wide age range. We recently encountered an incidental case sent for frozen section at the time of hysterectomy for endometrial carcinoma. Familiarity with this lesion will help prevent overinterpretation as a serous carcinoma. Read More

HBME1 and CK19 expression in non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) vs other follicular patterned thyroid lesions.

World J Surg Oncol 2021 May 8;19(1):143. Epub 2021 May 8.

Department of Pathology, University of New Mexico School of Medicine, MSC08 4640, 1 University of New Mexico, Albuquerque, NM, 87131, USA.

Background: Thyroid neoplasms with follicular architecture can have overlapping morphologic features and pose diagnostic confusion among pathologists. Various immunohistochemical stains have been investigated as potential diagnostic markers for PTC, among which HBME1 and CK19 have gained popularity. Non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) poses similar diagnostic challenges with interobserver variability and is often misdiagnosed as adenomatoid nodule or follicular adenoma.

Healthcare (Basel) 2021 Apr 1;9(4). Epub 2021 Apr 1.

Hallym University Medical Center, Hallym Institute of Translational Genomics and Bioinformatics, Anyang 14068, Gyeonggi-do, Korea.

Limited data are available on the diagnostic utility of circulating tumor DNA (ctDNA) in early-stage thyroid cancers for , , , and promoter mutations, which are known detectable markers for thyroid cancers. Here, we analyzed the above driver mutations in ctDNA and matched neoplastic tissues from patients with early-stage thyroid cancers in order to investigate diagnostic utility of circulating markers in distinguishing from other mimicking thyroid lesions and healthy individuals. In total, 73 matched neoplastic tissue and plasma samples [thyroid cancers (n = 62), benign thyroid disorders (n = 8), and parathyroid lesions (n = 3)] and 54 plasma samples from healthy individuals (as controls) were analyzed for , , , and promoter mutations using peptide nucleic acid clamp real-time PCR.

Ear Nose Throat J 2021 Apr 29:1455613211003805. Epub 2021 Apr 29.

Department of Otolaryngology-Head and Neck, Maxillofacial Surgery, Israel.

Objective: The presence of clinically detectable papillary thyroid carcinoma (PTC) metastases in the lateral neck is an indication for neck dissection (ND) and thyroidectomy. Although there is a consensus regarding the importance of therapeutic selective ND of involved levels II to IV in patients with clinically evident locoregional metastatic disease, the prognostic benefit of level V prophylactic ND remains debatable.

Methods: All patients who underwent thyroidectomy with ND for metastatic PTC between 2006 and 2019 were included in a single-institution retrospective study. Read More

Time to Surgery and Thyroid Cancer Survival in the United States.

Ann Surg Oncol 2021 Jul 25;28(7):3556-3565. Epub 2021 Mar 25.

Section of Endocrine Surgery, Department of Surgery, Beth Israel Deaconess Medical Center, Boston, MA, USA.

Background: Longer time to surgery worsens survival in multiple malignancies, including lung, colorectal, and breast cancers, but limited data exist for well-differentiated thyroid cancer. We sought to investigate the impact of time to surgery on overall survival in patients with papillary thyroid cancer.

Department of Oral and Maxillofacial Surgery, University of Medicine and Pharmacy of Craiova, Romania.

The literature date estimated that about 5% of all oral cavity cancers are hard palate cancers while soft palate cancers account for about 5-12% of oropharyngeal cancers.
