Endoscopic thyroidectomy (ET) via an axillo-breast (ABA), axillary or breast approach (BA) is effective for treatment of unilateral papillary thyroid microcarcinoma (PTMC). However, several disadvantages still exist, including inconvenience for using endoscopic instruments and poor cosmetic results. Here, we introduced a modified ABA (MABA) to overcome these disadvantages and evaluated its therapeutic outcomes by comparison with conventional BA.Fifty-five patients undergoing ET via MABA (n = 22) or BA (n = 33) for PTMC were retrospectively enrolled between June 2012 and June 2015...

OBJECTIVES: Preclinical studies showed that BRAF mutation significantly reduced radioiodine uptake and decreased the sensitivity to radioactive iodine (RAI) therapy. However, clinical data regarding its role in therapeutic decision making with respect to RAI therapy are currently insufficient. Thus, this study aimed to evaluate the effect of BRAF mutation on the clinical response to RAI therapy for papillary thyroid microcarcinoma (PTMC) with intermediate-risk to high-risk features. PATIENTS AND METHODS: From January 2012 and October 2015, consecutive patients with PTMC with intermediate-risk to high-risk features who underwent RAI therapy were retrospectively included...

BACKGROUND: The incidence of papillary thyroid microcarcinoma (PTMC) is increasing; however, it is not clear whether this reflects an increase in the incidence of incidental or in that of non-incidentally (presurgically) discovered PTMC (IPTMC vs. NIPTMC). We assessed the incidence of IPTMC and NIPTMC over the past 9 years, to discern whether the increase in PTMC incidence is due to improved diagnostics or to a real increase in the incidence. METHODS: We performed a retrospective chart review of 4327 patients who were consecutively admitted to and surgically treated for thyroid pathology at a single institution...

OBJECTIVES: Papillary thyroid carcinoma with a maximum tumor diameter no more than 10 mm is defined as papillary thyroid microcarcinoma (PTMC). The proportion of newly diagnosed PTMC has increased significantly in recent years. Different guidelines have different comments about optimal management of PTMC, especially on prophylactic central lymph node (CLN) dissection. The aim of the present study is to analyze the risk factors for CLN metastases in patients with PTMC. METHODS: A total of 4389 patients underwent thyroid surgery at our center from January 2017 to March 2018, and 2129 patients with PTMC were selected and assessed retrospectively...

Background: Poly(trimethylene carbonate) (PTMC) has wide biomedical applications in the field of tissue engineering, due to its biocompatibility and biodegradability features. Its common manufacturing involves photofabrication, such as stereolithography (SLA), which allows the fabrication of complex and controlled structures. Despite the great potential of SLA-fabricated scaffolds, very few examples of PTMC-based drug delivery systems fabricated using photo-fabrication can be found ascribed to light-triggered therapeutics instability, degradation, side reaction, binding to the macromers, etc...

BACKGROUND: Approximately half of the documented increases in differentiated thyroid carcinoma is due to identification of papillary thyroid microcarcinomas (PTMCs). Knowing whether PTMC is aggressive is required for proper treatment, but until now, there has been no method for assessing these traits and understanding the underlying mechanisms for aggressiveness. METHODS: We performed whole-exome sequencing of 16 PTMCs and matched normal thyroid tissues and GO/KEGG analysis to study genetic alterations and biological consequences associated with aggressive PTMCs, and then sequenced these genes using a next-generation gene-panel approach in an additional 70 PTMC samples including aggressive (n = 50) and non-aggressive (n = 20) groups...

Rheumatic heart disease (RHD) is a major health hazard in most developing countries as well as sporadically in developed economies with high prevalence rates. Mitral stenosis is among the important morbid valvular conditions accounting for 25% of RHD cases. Percutaneous transmitral commissurotomy (PTMC) using Inoue balloon is the standard treatment for severe mitral stenosis with favorable Wilkins score. In certain cases it is difficult to cross mitral valve (MV) either due to dilated left atrium (LA), low septal puncture, or severe mitral valvular and subvalvular stenosis leading to prolonged procedure time or failure of PTMC procedure...

The standard treatment of papillary microcarcinomas (mPTC; ≤1 cm) regardless of their size, was similar to the advanced ones till the recent past: immediate surgery ± radioactive iodine (RAI) therapy. However, the American Thyroid Association (ATA) 2015 guidelines accept the active surveillance in selected cases. We performed a retrospective analysis on the clinical data of 103 patients with PTmC in a single (62.1%) or multiple nodes (37.9%), treated with immediate surgery followed in most cases by postoperative RAI between 2001 and 2010...

BACKGROUND: Active surveillance has been introduced as a management option for low-risk papillary thyroid microcarcinoma (PTMC) due to its mostly indolent course. METHODS: This was a multicenter study of 370 PTMC patients who underwent active surveillance more than one year. The changes in volume and maximum diameter between initial and last ultrasonography were evaluated to identify the natural course of PTMC during active surveillance. RESULTS: Patients' age at diagnosis was 51 ± 12 years, and 110 (30%) patients were <45 years of age...

Purpose: Active surveillance (AS) of low-risk papillary thyroid microcarcinoma (PTMC) may reduce the risk of overtreatment of clinically insignificant cancer. However, the absence of predictor for the progression of PTMC resulted in treatment delay and potentially compromising cure of aggressive disease. Therefore, to anticipate potential damage of delayed surgery, we investigated the oncologic outcomes of patients with low-risk PTMC initially eligible for AS except clinically apparent lymph node metastasis (LNM), imitating delayed surgery with neck dissection...

Papillary thyroid microcarcinoma (PTMC) accounts for nearly 50% of newly diagnosed PTC cases. There is considerable debate in literature about the clinicopathologic features and prognostic significance of PTMC and whether it should be treated as a separate entity. Due to lack of agreement and supportive data, the consensus study group that established the criteria for non-invasive thyroid neoplasm with papillary-like features (NIFTP) kept its size above 1 cm i.e., excluding PTMC from this new group. As a result, to date, some patients diagnosed with PTMC get aggressive treatments such as partial or total thyroidectomy and even radioactive iodine ablation...

MV repair in the rheumatic population is feasible with acceptable long-term results. Incidence of mitral stenosis (MS) following mitral valve (MV) repair for severe rheumatic mitral regurgitation (MR) and usefulness of percutaneous transluminal mitral valvuloplasty in these patients is not described in literature. We report a case of successful PTMC in severe MS following MV repair for severe rheumatic MR.

BACKGROUND: Solitary papillary thyroid microcarcinoma (PTMC) without gross extrathyroidal extension (ETE) were the main candidates for active surveillance (AS). Predictive factors of lateral lymph node metastasis (LLNM) in solitary PTMC without gross ETE were essential but still unknown. METHODS: Altogether, 171 patients of solitary PTMC without gross ETE were enrolled in our study and divided into two groups. Group A: 123 patients without lateral lymph node dissection (LLND) were considered to be LLNM negative because there was no lateral recurrence by at least 8-year follow up for all patients...

The treatment of papillary thyroid microcarcinoma (PTMC) remains deeply controversial. In this study, we investigated the prognosis of patients who underwent biopsy alone, as compared with other forms of thyroidectomy approaches. We sought to provide reference information for treatment selection in cases of PTMC.The analysis included a large cohort of 34,972 PTMC patients from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2013. Survival was examined by Kaplan-Meier analyses with log-rank tests, Cox proportional-hazards regression analyses, and propensity score matching analyses...
