Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in advanced thyroid cancer (TC) patients; single-center experience

Simeakis George , Paschou Stavroula A. , Alevizaki Maria , Saltiki Katerina

Objectives: Patients suffering from pulmonary or/and neoplastic disease are at higher risk of developing serious illness from SARS-CoV-2. TC patients with lung metastases are classified as high-risk for severe CoV-2 disease. Aim of this study was to investigate SARS-CoV-2 prevalence and severity in this particular subgroup of patients.Methods: Out of 28 patients with metastatic Differentiated Thyroid Cancer (DTC) and 21 patients with met...

Occurrence of second primary malignancy in medullary thyroid cancer (MTC) patients

Simeakis George , Saltiki Katerina , Zapanti Evangelia , Kassis Evanthia , Alevizaki Maria

Objectives: Coexistence of two different malignancies is frequently reported. Sometimes occurs in the context of well-established syndromes like MEN2. Rearranged during transfection (RET), is an oncogenic driver activated in different kinds of neoplasias such as: MTC, Differentiated Thyroid Cancer (DTC), Non-Small Cell Lung Cancer (NSCLC). We have previously reported an increased prevalence of DTC in familial MTC patients carrying the RET (G533C) mutation. Ai...

Medullary Thyroid Carcinoma (MTC); unusual metastatic sites: Two case reports

Kazakou Paraskevi , Simeakis George , Alevizaki Maria , Saltiki Katerina

Background: MTC tends to metastasize early in the course of the disease affecting usually regional lymph nodes; in 7–23% of patients distant metastases may be present at diagnosis (common metastatic sites:liver, lungs, bone). We present two MTC cases with unusual metastases to the breast, pancreas and mandible.Case presentation: Patient No 1: a 48-year-old female was diagnosed with MTC in 1990. Total thyroidectomy was performed followed by neck diss...

Treatment modalities in DTC patients with neck disease persistence. Second surgical intervention is more beneficial than only radioiodine (RAI) treatment

Saltiki Katerina , Simeakis George , Konstantakatou Panagiota , Sapounas Spyros , Alevizaki Maria

Objectives: DTC has a favorable clinical course. A small percentage of patients undergoing surgery and RAI ablation may have local disease persistence and further therapeutic interventions may be needed such as further RAI administration following or not a second surgery. We investigated whether additional therapeutic interventions may be beneficial for the clinical course in DTC patients with disease persistence.Methods: 812 DTC patients (men 25.7%, age...

Novel somatic mutations in sporadic MTC (spMTC); clinical utility of NGS in precision medicine

Simeakis George , Romei Cristina , Ciampi Raffaele , Ramone Teresa , Saltiki Katerina , Elisei Rossella , Alevizaki Maria

Objectives: Distant metastases in MTC adversely affect disease prognosis. Somatic mutations in spMTC as well as Variant Allele Frequency (VAF) have been related to tumor burden, disease course and the response to TKIs. The aim of this study is to report three cases of nucleotide (nt) insertions/deletions (indels) in the RET oncogene in relation to disease course/response to TKIs.Methods: Of 195 spMTC patients followed-up in Dept. Clinical Therap...

Radioiodine (RAI) refractory differentiated thyroid cancer (DTC): outcome and prognostic factors for DISEASE progression

Saltiki Katerina , Simeakis George , Anagnostou Elli , Apostolakis Michalis , Zapanti Evangelia , Anastasiou Eleni , Alevizaki Maria

Introduction: Patients diagnosed with DTC have excellent prognosis. A small percentage of patients with disease persistence do not respond to treatment with RAI (RAI-refractory DTC) and have low median survival (3.5 years). We investigated the prognostic factors and the disease course in patients with RAI-refractory DTC.Methods: Of all DTC patients (n=1160) followed-up in our department in recent years, 800 received RAI treatment and were classified in 2...

Clinical features of medullary thyroid carcinoma (MTC) in simultaneous occurrence with differentiated thyroid cancer (DTC)

Simeakis George , Saltiki Katerina , Anagnostou Elli , Apostolakis Michalis , Vasileiou Vasiliki , Alevizaki Maria

Objective: Simultaneous occurrence of MTC and DTC is frequently found. It is unclear whether there is a common pathogenic mechanism. Aim of our study was to characterize clinical features of MTC when coexisting with DTC.Methods: Of 273 MTC patients followed-up in our department 39 (14.3%) had MTC simultaneously with DTC. They were divided in 4 subgroups according to size. Clinical histopathological data were recorded.Results: The p...

Thyroid function in pregnant women; relation to Gestational Diabetes Mellitus (GDM) and Body Mass Index (BMI)

Simeakis George , Vogiatzi Evangelia , Konstantakou Panagiota , Zapanti Evangelia , Saltiki Katerina , Alevizaki Maria , Anastasiou Eleni

Objectives: The interplay between thyroid function and metabolic state has been studied in many population subgroups. For pregnant women thyroid and metabolic parameters, including glucose homeostasis, are of great importance for a successful outcome. We examined aspects of thyroid function in relation to GDM and BMI in pregnant women referred to our Department.Methods: We studied 520 women during 24th – 32nd gestation week. De...

The significance of postoperative calcitonin (CT) levels in the evaluation of disease course in medullary thyroid cancer (MTC) patients

Saltiki Katerina , Simeakis George , Vogiatzi Evangelia , Kassi Eva , Zapanti Evangelia , Alevizaki Maria

Aim: Postoperative calcitonin (postCT) is a prognostic factor for disease progression in MTC patients. We evaluated the disease course in patients with persistently elevated post-CT.Methods: Of all MTC patients (n=273) followed-up in our Unit (for 1–37, median 7 years), 140 (39.3% men, 67.1% sporadicMTCs) had persistently elevated postCT (≥2.0 pg/ml). Clinical and biochemical data were recorded. Patients were classified in four groups...
