BACKGROUND: The treatment of papillary thyroid microcarcinoma (PTMC) patients is controversial, as PTMC is often found incidentally and its prognosis is quite good. Because lymph node metastasis (LNM) is one of the main predictors of recurrence and impacts the survival rate of PTMC patients, this study aims to retrospectively identify the clinical factors that increase the risk of LNM and/or recurrence and can then be used to separate clinically unfavorable PTMCs from the rest and to help guide their treatment accordingly...

Objective: Thyroid-stimulating hormone (TSH) is a growth factor affecting initiation or progression of papillary thyroid cancer (PTC), which supports TSH suppressive therapy in PTC patients. In patients with papillary thyroid microcarcinoma (PTMC) during active surveillance, however, the association between serum TSH level and growth of PTMC has not been demonstrated. Patients: We analyzed 127 PTMCs in 126 patients under active surveillance with serial serum TSH measurement and ultrasonography...

3D-microbatteries (3D-MBs) impose new demands for the selection, fabrication and compatibility of the different battery components. Herein, solid polymer electrolytes (SPEs) based on poly(trimethylene carbonate) (PTMC) have been implemented in 3D-MB systems. 3D electrodes of two different architectures, LiFePO4-coated carbon foams and Cu2O-coated Cu nanopillars, have been coated with SPEs and used in Li-cells. Functionalized PTMC with hydroxyl end groups was found to enable uniform and well-covering coatings on LiFePO4-coated carbon foams, which was difficult to achieve for non-functionalized polymers, but the cell cycling performance was limited...

Liver cancer is a globally leading malignancy that has a poor five-year survival rate of less than 20%. The systemic chemotherapeutics are generally ineffective for liver cancers partly due to fast clearance and low tumor uptake. Here, we report that GE11 peptide functionalized polymersomal doxorubicin (GE11-PS-DOX) effectively targets and inhibits epidermal growth factor receptor (EGFR)-positive SMMC7721 orthotopic human liver tumor xenografts in mice. GE11-PS-DOX with a GE11 surface density of 10% displayed a high drug loading of 15...

Screening out patients who do not require immediate surgery is a growing trend in the field of thyroid research. In this study, we retrospectively compared the application of two surveillance selection criteria in 1001 patients who had undergone surgical treatment of papillary thyroid microcarcinoma (PTMC): low-risk PTMC characteristics defined by Kuma Hospital and CATO consensus on PTMC management of active surveillance. Treatment outcomes were compared between groups. We then analyzed the prognostic indicators of patients who could be managed by surveillance...

BACKGROUND: The optimal extent of surgery for patients with papillary thyroid microcarcinoma (PTMC), tumors ≤1 cm, is controversial because survival is excellent regardless of approach. The objective of this study was to investigate patient and surgeon decision-making about the extent of surgery for PTMC. MATERIALS AND METHODS: We conducted a retrospective review of thyroid cancer patients operated on at a single institution from 2008-2016. To examine decision-making about the extent of surgery, we performed a discourse analysis on all available documentation looking for patient or surgeon reasons...

OBJECTIVE: The role of routine central lymph node dissection (CLND) for clinically central lymph node negative (CN0) papillary thyroid microcarcinoma (PTMC) remains uncertain. We aim to determine the predictive factors for central lymph node metastasis (CLNM) in papillary thyroid microcarcinoma. PATIENTS AND METHODS: A total of 273 patients diagnosed with clinically central lymph node negative PTMC from 2014 to 2016 were included. The predictive risk factors for CLNM were analyzed with respect to age, sex, tumor size, tumor multifocal, lymphadenectasis of lateral neck, capsular invasion, extra capsular spread (ECS), coexistence of chronic lymphocytic thyroiditis (Hashimoto thyroiditis, HT) and nodular goiter (NG), BRAFV600E mutation and subtype of papillary thyroid carcinoma (PTC)...

A novel medical adhesive was prepared by blending poly(lactic acid) (PLA) with poly(trimethylene carbonate) (PTMC) in ethyl acetate, and the two materials were proven to be biodegradable and biocompatible. The medical adhesive was characterized by ¹H nuclear magnetic resonance (¹HNMR), gel permeation chromatography (GPC), scanning electron microscopy (SEM) and differential scanning calorimetry (DSC). The water vapor transmission rate (WVTR) of this material was measured to be 7.13 g·cm(-2)·24 h(-1). Its degree of comfortability was confirmed by the extensibility (E) and the permanent set (PS), which were approximately 7...

Classical papillary thyroid microcarcinoma (PTMC) is a variant of papillary thyroid carcinoma (PTC) known to have excellent prognosis. It has a mortality of 0.3%, even in the presence of distance metastasis. The latest American Thyroid Association guidelines state that although lobectomy is acceptable, active surveillance can be considered in the appropriate setting. We present the case of a 37-year-old female with a history of PTMC who underwent surgical management consisting of a total thyroidectomy. Although she has remained disease-free, her quality of life has been greatly affected by the sequelae of this procedure...

The prognostic significance of gender remains controversial for papillary thyroid carcinoma (PTC). In this study, we investigated the associations between gender and prognosis in a large cohort of patients with PTC or PTMC that was diagnosed in 2010-2013 and recorded in the Surveillance, Epidemiology, and End Results cancer registry. The mean ± standard deviation duration of survival for all patients with PTC during the study period was 21.47 ± 14.04 months. In Kaplan-Meier analyses of the entire cohort of PTC patients, survival curves for all-cause death and cancer-specific death declined more sharply for men than for women...

The association between autoimmune thyroid disease and thyroid cancer remains unclear. We performed a matched case-control study to assess the association between Hashimoto's thyroiditis and papillary thyroid microcarcinoma (PTMC). A total of 927 PTMC cases and 927 age- and gender- matched controls selected from the same population were recruited. Odds ratio (OR) with 95% confidence interval (95% CI) was used to assess the strength of the association between Hashimoto's thyroiditis and PTMC. Conditional logistic regression analysis was carried out, and stratified analyses by age, gender and types of thyroid antibodies were also performed...
