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...

BACKGROUND: In patients undergoing active surveillance of papillary thyroid microcarcinoma, definitive therapy-usually preceded by a definitive diagnostic procedure-is not recommended until evidence of disease progression is obtained, as stated in the American Thyroid Association guidelines. This is because the deferring of definitive diagnosis and therapy until disease progression has no impact on the disease-specific survival. This study evaluated the malignancy rate and probability of thyroid nodules, which was further stratified based on the size cutoff value of 1 cm, with suspicious findings on ultrasonography (US), by using various malignant stratification systems...

BACKGROUND: The incidence of papillary thyroid microcarcinoma (PTMC) has been increasing globally in the past few decades. PTMC does not have a distinctive morphology that results in differences in biological behavior. The aim of this study was to classify PTMCs according to the morphological features and explore the relationship with clinicopathological characteristics. Additionally, we sought to evaluate whether different variants of PTMC can be an independent predictor for lymph mode metastasis when considering other risk factors...

BACKGROUND: Large-volume lymph node metastasis (LNM) is associated with poor clinical outcomes in papillary thyroid microcarcinoma (PTMC) patients. However, sensitivity in the detection of central neck LNM on preoperative neck ultrasonography (US) is believed to be low. The aim of this study is to investigate the preoperative clinical factors associated with large-volume LNM in clinical N0 PTMC patients. METHODS: In all, 2329 clinical N0 PTMC patients who underwent total thyroidectomy with prophylactic central lymph node (LN) dissection were evaluated...

BACKGROUND: Most of the increase in thyroid cancer in recent decades has been due to papillary thyroid microcarcinoma (PTMC). We evaluated the efficacy of radioiodine remnant ablation (RRA) in patients with PTMC. METHODS: This historical cohort study included 1932 PTMC patients without lateral cervical lymph node (LN) or distant metastasis who underwent total thyroidectomy (TT) during the median 8.3 years of follow-up. The clinical outcomes of patients with or without RRA were compared using weighted logistic regression models with the inverse probability of treatment weighting (IPTW) method and considering risk factors, including age, sex, primary tumor size, extrathyroidal extension, multifocality, and central cervical LN metastasis...

Locoregional recurrence is common in papillary thyroid cancer PTC and an optimal surgical treatment with respect to the multifocal nature of the disease stays controversial. It is a retrospective analytical study design. 209 diagnosed PTCs managed at our institute were grouped into macro-PTC with a size of dominant focus >1 cm (unifocal n = 106 and multifocal n = 64) and micro-PTMC if size of all foci was <1 cm; (unifocal n = 16 and multifocal PTMC n = 23). The primary endpoint is recurrence and tumor free survival in each of the four groups...
