INTRODUCTION: Increased body mass index (BMI) is known to be associated with the high prevalence of Differentiated Thyroid Cancers (DTC); however data on its impact on survival outcome after thyroidectomy and adjuvant therapy is scanty. OBJECTIVE: We aimed to evaluate the impact of BMI on overall survival (OS) and disease free survival (DFS) rates in patients with DTC. METHODS: Between 2000 and 2011, 209 patients with DTC (papillary, follicular, hurthle cell) were treated with thyroidectomy followed by adjuvant radioactive iodine-131 (RAI) therapy and thyroid-stimulating hormone (TSH) suppression...

Context: Lobectomy is preferred in thyroid cancer to decrease surgical complications and avoid lifelong thyroid-hormone replacement. However, postoperative hypothyroidism, requiring thyroid-hormone replacement, may occur. Objective: We aimed to identify the incidence and risk factors of postoperative hypothyroidism to develop a surveillance strategy after lobectomy for papillary thyroid microcarcinoma (PTMC). Methods: This historical cohort study involved 335 PTMC patients treated by lobectomy...

BACKGROUND: There is growing acceptance that the increase in thyroid cancer incidence is in part a result of overdiagnosis of small low-risk papillary microcarcinomas (PMCs) with indolent clinical course. Although surgery is the cornerstone treatment for patients with PMCs, recent management guidelines are shifting toward inclusion of more conservative treatments such as active surveillance. There is little evidence on clinicians' experience in managing PMC patients and their attitudes toward treatment options, including their willingness to accept a nonsurgical option...

Alfred King-Yin Lam, Nassim Saremi
The aim of this systematic review is to study the features of cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC) by analysing the 129 documented cases in the English literature. The disease occurred almost exclusively in women. The median age of presentation for CMV-PTC was 24 years. Slightly over half of the patients with CMV-PTC had familial adenomatous polyposis (FAP). CMV-PTC presented before the colonic manifestations in approximately half of the patients with FAP. Patients with FAP often have multifocal tumours in the thyroid...

BACKGROUND: Population-based data on the development of kidney cancer as a second malignant neoplasm following the diagnosis of other common malignancies are rare. This clinical scenario has been evaluated within the Surveillance, Epidemiology, and End Results (SEER) database. MATERIALS AND METHODS: The SEER-9 database (1973-2013) was queried using the SEER*Stat program to determine the standardized incidence ratios (SIRs) of kidney cancer development following each one of 10 common invasive malignancies (colorectal, breast, prostate, lung, thyroid, corpus uteri, urinary bladder, kidney/renal pelvis, cutaneous melanoma, and non-Hodgkin lymphoma)...

OBJECTIVE: Metastatic lymph node ratio (MLNR) is a known significant predictor of disease-free survival in differentiated thyroid cancer. The authors investigated the ability of preoperative fluorine-18 fluorodeoxyglucose (F-FDG) PET/CT to predict recurrence after surgery with radioactive iodine therapy considering MLNR. PATIENTS AND METHODS: A total of 274 patients who underwent preoperative PET/CT and surgery with radioactive iodine therapy were enrolled. The tumor-to-liver uptake ratio on PET/CT was calculated by dividing the maximum standardized uptake value of a primary lesion by the mean standardized uptake value of the normal liver...

Papillary thyroid carcinoma is the most frequent histologic type of thyroid tumor. Few studies investigated the role of c-KIT expression in thyroid tumors, suggesting a role for this receptor and its ligand in differentiation and growth control of thyroid epithelium and a receptor loss following malignant transformation. We investigated and correlated c-KIT expression levels and two known markers of thyrocytes differentiation, PAX8 and TTF-1, in malignant and benign cytological thyroid samples. Moreover, we performed functional studies on human papillary thyroid carcinoma cell line to associated c-KIT expression to thyrocytes differentiation and tumor proliferation...

BACKGROUND: Noninvasive encapsulated follicular variant of papillary thyroid carcinoma, a diagnosis implying malignancy as a variant of papillary thyroid carcinoma (PTC), has recently been reclassified to noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) on surgical pathology. Due to the effects of such a recategorization on rate of malignancy and clinical management algorithms, it is imperative that we explore whether presurgical fine-needle aspiration can differentiate NIFTP from PTC and follicular adenoma (FA)...

Papillary thyroid cancer (PTC) is the most common tumor subtype of thyroid cancer. However, not all PTCs are responsive to current surgical and radioiodine treatment. The well-established clinical prognostic factors include tumor size, lymph node/distal metastasis, and extrathyroidal invasion. The RET/PTC-RAS-BRAF linear molecular signaling cascade is known to mediate PTC pathogenesis. However, whether presence of BRAF mutation, the most common genetic alteration in PTC, can affect PTC behavior and prognosis is controversial...

BACKGROUND: Prognostic factors are essential for risk stratification in patients with differentiated thyroid carcinoma (DTC). The role of stimulated postoperative thyroglobulin (sPOTg) has been well-established in adult DTC population but it remains unclear in children and adolescents. Here, we aimed to evaluate potential prognostic factors in children and adolescents with DTC, with special emphasis on sPOTg analysis. METHODS: Individuals aged 18 years or younger at diagnosis were selected from a cohort of DTC patients attending the thyroid clinic of a tertiary university-based hospital...

A 25-year-old woman had total thyroidectomy and iodine-131 ablation therapy for papillary thyroid carcinoma. Whole body imaging on the 7(th) day of therapeutic activity demonstrated radioiodine uptake in the remnant tissue and intense heterogeneous uptake at the sacral region prominently in the posterior image. Initial interpretation was suspicious for sacral metastasis. Technetium-99m-methylene diphosphonate bone scan demonstrated normal bone uptake and the absence of left kidney. On blood-pool phase of bone scan, the absence of left renal activity and an extra area of uptake in the sacral region suggestive of pelvic kidney were noticed...

PURPOSE: The lymph node ratio (LNR) is an important prognostic factor in papillary thyroid carcinoma (PTC), but micrometastases in cervical lymph nodes (LNs) are not of great clinical importance. In this study, we analyzed the accuracy of prediction of the prognosis depending on whether micrometastases were included in the number of metastatic LNs when calculating LNR. METHODS: The study included 353 PTC patients who underwent total thyroidectomy with neck LN dissection, and calculated LNR by 2 methods according to whether micrometastases were included in the number of metastatic LNs: Method 1 did not and method 2 did include...
