Non-functioning parathyroid cystic tumour: malignant or not? Report of a case
2017
Parathyroid carcinoma (PC) is a very rare endocrine tumour, usually characterized by symptoms such as a neck mass, dysphonia, severe hypercalcemia exceeding 140 mg/L and elevated serum parathyroid hormone levels, even more than 5 times the upper limit of normal. Non-functioning parathyroid cancer is extremely rare and, in this case, its pre-operative diagnosis is often difficult. A 54-year old female patient, referring dysphagia and dysphonia, underwent neck ultrasound and neck CT. A left thyroid nodule, probably cystic, was found. It presented caudal extent on anterior mediastinum causing compression of the left lateral wall of the trachea. The preoperative calcemia was into the normal ran…
The antiapoptotic protein BAG3 is expressed in thyroid carcinomas and modulates apoptosis mediated by tumor necrosis factor-related apoptosis-inducin…
2007
Abstract Context: We previously showed that BAG3 protein, a member of the BAG (Bcl-2-associated athanogene) co-chaperone family, modulates apoptosis in human leukemias. The expression of BAG3 in other tumor types has not been extensively investigated so far. Objective: The objective of this study was to analyze BAG3 expression in thyroid neoplastic cells and investigate its influence in cell apoptotic response to TNF-related apoptosis-inducing ligand (TRAIL). Design, Setting, and Patients: We investigated BAG3 expression in human thyroid carcinoma cell lines, including NPA, and the effect of BAG3-specific small interfering RNA on TRAIL-induced apoptosis in NPA cells. Subsequently, we analyz…
Prädiktive genetische Untersuchungen: Individualisierung von Diagnostik und Therapie bei Familien mit multipler endokriner Neoplasie Typ II
2008
BACKGROUND AND OBJECTIVE When multiple endocrine neoplasia type 2 (MEN2) is suspected, genetic tests are at the centre of screening procedures. It was the aim of this study to compare the diagnostic value of molecular biological investigations with that of conventional biochemical tests. PATIENTS AND METHODS The study cohort consisted of all 144 patients cared for in our department since 1990 with the suspected diagnosis of MEN2 (evidence of a medullary thyroid carcinoma [MTC]), coexistence of two MEN2 tumours or a family history of MEN2. 14 of the 144 patients (from 12 families) were already known to have an hereditary MTC, while the remaining 130 had been referred for further diagnostic i…
Prognostische Bedeutung des e-Cadherin beim papillären Schilddrüsencarcinom
1998
The prognostic significance of e-cadherin in papillary thyroid carcinoma was evaluated in a retrospective study. From September 1985 to December 1996, 113 patients underwent surgery for papillary thyroid carcinoma. Seventy-eight formalin-fixed, paraffin-embedded tissue samples were available for immunohistochemical analysis of e-cadherin expression. In 74 of these 78 patients the postoperative course is known for 2 months to 35.2 years (median 3.6 years, mean: 4.9 +/- 4.8 years). Reduced or negative e-cadherin expression ( 20%. Statistical analysis revealed e-cadherin expression ( 20%), synchronous distant metastasis (M0/pM1, cM1) and radicality of resection (R0/R1, 2) as significant risk f…
Skip metastases to lateral cervical lymph nodes in differentiated thyroid cancer: a systematic review.
2019
Abstract Papillary thyroid carcinoma is a slow-growing cancer with a generally good prognosis that sometimes have an aggressive behaviour. Metastases to neck lymph nodes is the first step of the diffusion. The central neck compartment is involved most commonly. The ipsilateral lateral neck compartments are usually involved afterwards, and the involvement of the contralateral one is considered a quite rare occurrence. In more rare cases, metastases to lateral neck compartment without central lymph node metastasis (so called “skip metastases”) could be observed. Aim of this literature review study is to analyse the average incidence, pattern and risk factors of this occurrence. This study was…
Hemithyroidectomy versus total thyroidectomy in the intermediate-risk differentiated thyroid cancer: the Italian Societies of Endocrine Surgeons and …
2021
The surgical treatment of the intermediate-risk DTC (1–4 cm) remains still controversial. We analyzed the current practice in Italy regarding the surgical management of intermediate-risk unilateral DTC to evaluate risk factors for recurrence and to identify a group of patients to whom propose a total thyroidectomy (TT) vs. hemithyroidectomy (HT). Among 1896 patients operated for thyroid cancer between January 2017 and December 2019, we evaluated 564 (29.7%) patients with unilateral intermediate-risk DTC (1–4 cm) without contralateral nodular lesions on the preoperative exams, chronic autoimmune thyroiditis, familiarity or radiance exposure. Data were collected retrospectively from the clini…
Predictors of Central Compartment Involvement in Patients with Positive Lateral Cervical Lymph Nodes According to Clinical and/or Ultrasound Evaluati…
2021
Lymph node neck metastases are frequent in papillary thyroid carcinoma (PTC). Current guidelines state, on a weak level of evidence, that level VI dissection is mandatory in the presence of latero-cervical metastases. The aim of our study is to evaluate predictive factors for the absence of level VI involvement despite the presence of metastases to the lateral cervical stations in PTC. Eighty-eight patients operated for PTC with level II–V metastases were retrospectively enrolled in the study. Demographics, thyroid function, autoimmunity, nodule size and site, cancer variant, multifocality, Bethesda and EU-TIRADS, number of central and lateral lymph nodes removed, number of positive lymph n…
