OBJECTIVE: Papillary thyroid microcarcinoma (PTMC) accounts for most of the increase in thyroid cancer in recent decades. We compared clinical outcomes and surgical complications of lobectomy and total thyroidectomy (TT) for PTMC patients. DESIGN AND METHODS: In this retrospective individual risk factor matched cohort study, 2031 patients with PTMC were initially included. Patients who underwent lobectomy or TT were one-to-one matched according to individual risk factors, including age, sex, primary tumor size, extrathyroidal extension, multifocality, and cervical lymph node (LN) metastasis...

Recent findings demonstrated that a subset of papillary thyroid cancers (PTCs) is characterized by reduced expression of the von Hippel-Lindau (VHL) tumor suppressor gene, and that lowest levels associated with more aggressive PTCs. In the present study, the levels of the two VHL mRNA splicing variants, VHL-213 (V1) and VHL-172 (V2), were measured in a series of 96 PTC and corresponding normal matched tissues by means of quantitative RT-PCR. Variations in the mRNA levels were correlated with patients' clinicopathological parameters and disease-free interval (DFI)...

Certain cell types function as factories, secreting large quantities of one or more proteins that are central to the physiology of the respective organ. Examples include surfactant proteins in lung alveoli, albumin in liver parenchyma, and lipase in the stomach lining. Whole-genome sequencing analysis of lung adenocarcinomas revealed noncoding somatic mutational hotspots near VMP1/MIR21 and indel hotspots in surfactant protein genes (SFTPA1, SFTPB, and SFTPC). Extrapolation to other solid cancers demonstrated highly recurrent and tumor-type-specific indel hotspots targeting the noncoding regions of highly expressed genes defining certain secretory cellular lineages: albumin (ALB) in liver carcinoma, gastric lipase (LIPF) in stomach carcinoma, and thyroglobulin (TG) in thyroid carcinoma...

BACKGROUND: There are currently no effective therapeutic methods for locally recurrent, metastatic, or progressive radioactive iodine (RAI)-refractory differentiated thyroid cancer. However, multitargeted tyrosine kinase inhibitors (TKIs) such as lenvatinib or sorafenib have been approved for patients with RAI-refractory differentiated thyroid cancer as a second targeted therapy, and these agents can prolong patient survival. However, several cases have been reported that TKIs have caused fatal complications such as fistula formation or bleeding...

BACKGROUND: Cervical lymph node metastasis is a vital factor associated with local recurrence in papillary thyroid carcinoma (PTC). Tumor size is used in the staging of PTC because it represents the tumor load. This study compared two methods of tumor size assessment to predict tumor behavior in the relationship between size and cervical node involvement for patients with PTC. METHODS: The study enrolled 1084 patients who underwent initial thyroid surgery and had a pathologic diagnosis of PTC between 2012 and 2014 at The Second Affiliated Hospital Zhejiang University School of Medicine...

OBJECTIVE: Papillary thyroid cancer (PTC) could behave differently in prepubertal than in pubertal children and between children and adults. BRAF gene activating mutations may associate with PTC by creating aberrant activation. We aimed to evaluate clinicopathological characteristics of PTC patients with emphasis on the pubertal status and investigate the association of BRAFV600E mutation with disease characteristics. METHODS: Medical records of 75 patients with PTC were reviewed retrospectively...

BACKGROUND: Many studies have reported several transcriptionally deregulated microRNAs (miRNAs) in papillary thyroid cancer (PTC) tissue in comparison with benign thyroid nodules and normal thyroid tissues. However, the correlation between miRNA expressions and PTC recurrence still remains unclear. METHODS: The PTC patients who scheduled to undergo total thyroidectomy by the same surgical team in Ningbo NO.2 Hospital from March 1998 to March 2008 were enrolled in this study...

Targeted therapies in endometrial cancer (EC) using kinase inhibitors rarely result in complete tumor remission and are frequently challenged by the appearance of refractory cell clones, eventually resulting in disease relapse. Dissecting adaptive mechanisms is of vital importance to circumvent clinical drug resistance and improve the efficacy of targeted agents in EC. Sorafenib is an FDA-approved multitarget tyrosine and serine/threonine kinase inhibitor currently used to treat hepatocellular carcinoma, advanced renal carcinoma and radioactive iodine-resistant thyroid carcinoma...

Purpose: The current TNM staging system for papillary thyroid cancer (PTC), which is based on tumor diameter, may not precisely reflect the true tumor burden. Therefore, we investigated whether preoperative tumor volume might more accurately reflect tumor burden and predict prognosis in patients with T1N0 PTC than preoperative tumor diameter. Materials and Methods: We retrospectively reviewed data from 1,659 patients with T1N0 PTC, and after exclusion, a total of 1,081 patients were ultimately included...

Differentiated thyroid cancer is the most common form of thyroid cancer and its prognosis is favourable in most cases. Suppression of thyroid stimulating hormone (TSH) by supra-physiological thyroid hormone replacement has been the mainstay of long-term management for over 60 years. However, evidence for a beneficial outcome of TSH suppression is conflicting and intervention must be balanced against adverse effects, particularly affecting the cardiovascular system and skeleton. Here we discuss the role of TSH suppression in the long-term management of differentiated thyroid cancer in the context of risk stratification for disease recurrence and the latest clinical guidelines...

Ga-PSMA PET/CT is increasingly used to assess prostate cancer. Avid Ga-PSMA uptake by thyroid cancer and renal cell carcinoma (RCC) has been reported in few cases. A 75-year-old man who received a diagnosis of RCC in 2006 and prostate cancer in 2009 presented with elevated prostate-specific antigen levels (0.7 ng/mL) following prostatectomy. Ga-PSMA PET/CT showed avid Ga-PSMA uptake in 1 pelvic and 1 retroperitoneal lymph node and focal Ga-PSMA accumulation in the thyroid. Excised retroperitoneal lymph node and thyroid tissues showed metastases from RCC, whereas the pelvic lymph node exhibited metastasis from prostate cancer...

Assessing the impact of kinase in gene fusion is essential for both identifying driver fusion genes (FGs) and developing molecular targeted therapies. Kinase domain retention is a crucial factor in kinase fusion genes (KFGs), but such a systematic investigation has not been done yet. To this end, we analyzed kinase domain retention (KDR) status in chimeric protein sequences of 914 KFGs covering 312 kinases across 13 major cancer types. Based on 171 kinase domain-retained KFGs including 101 kinases, we studied their recurrence, kinase groups, fusion partners, exon-based expression depth, short DNA motifs around the break points and networks...

: The incidence of thyroid cancer (TC) is being significantly increased. A significant percentage consists of metastatic cancer (MCP) in particular in the anterior-superior mediastinal lymph nodes (Group 7). MATERIAL AND METHODS: 153 out of 324 patients with metastatic TC underwent video-assisted lymphadenectomy of group 7 of lymph nodes. The operations were combined with interventions on the primary tumor or on cervical lymph nodes in case of recurrence. RESULTS: The possibility of long-term survival (over 10 years) was studied in more than 80% of cases...

Background This study was conducted to compare the staging systems for the prediction of long-term disease status in patients with well-differentiated thyroid carcinoma (WDTC), and find out the earliest postoperative period predictor of long-term persistence/recurrence of disease. Methods Patients with WDTC (n=356, age 41.5 ± 12.7 years) followed for at least 5 years (12.3 ± 5.0 years) after thyroidectomy and 131I remnant ablation at a tertiary regional hospital in Taiwan were retrospectively studied. Each patient was risk-stratified using the American Joint Cancer Committee (AJCC) (stage I-IV), American Thyroid Association (ATA) (low, intermediate, high risk) staging systems after operation and first 131I remnant ablation and using response to initial therapy reclassification (RTR) (excellent, indeterminate, biochemical incomplete, structural incomplete response) system, which is determined 6-24 months after the first 131I ablation...

: Metastatic thyroid cancer is an uncommon condition to be present at the time of pregnancy, but presents a challenging paradigm of care. Clinicians must balance the competing interests of long-term maternal health, best achieved by iatrogenic hyperthyroidism, regular radioiodine therapy and avoidance of dietary iodine, against the priority to care for the developing foetus, with inevitable compromise. Additionally, epidemiological and cellular data support the role of oestrogen as a growth factor for benign and malignant thyrocytes, although communicating the magnitude of this risk to patients and caregivers, as well as the uncertain impact of any pregnancy on long-term prognosis, remains challenging...
