THE TUMOR CELL IDENTITY: A GATEWAY TO THE MOLECULAR BASIS OF MALIGNANT TRANSFORMATION
It is now well established that within a tumor mass there is a hierarchical organization, stemming from a cell subpopulation retaining the highest tumorigenic potential, referred as cancer stem cells (CSCs), responsible for tumor initiation and progression. Although recent advances in stem cell biology led to the acquisition of new view of thyroid carcinoma as a stem cell disease, the cellular origin of thyroid CSCs remains unknown. In Chapter 1 it is critically discussed the potential role of thyroid stem cells (TSCs) in light of the available information on the oncogenic role of genetic alterations underlying the thyroid carcinogenesis. Understanding the key events that regulate thyroid t…
Anaplastic thyroid cancer: A case series with a wide spectrum of treatment in emergency
2019
Anaplastic thyroid carcinoma (ATC) is one of the most aggressive malignancies of the neck, and for the majority of these patients the cause of death is a compromised airway, metastatic disease, superior vena cava syndrome, asphyxiation, or exsanguination. In case of the airway being compromised, emergency treatment is mandatory but not well defined. We report 4 different kinds of acute presentation of complications. Anaplastic thyroid cancer; diagnostic, clinical and prognostic indication, evaluation of choice of treatment are discussed. The spectrum of treatment varies from observation and preservation of the airway from a tracheostomy to extensive surgery. When a potentially curative rese…
Development of Histologically Verified Thyroid Diseases in Women Operated for Breast Cancer: A Review of the Literature and a Case Series
2022
Background: The possible relationships between breast and thyroid diseases have been reported in the literature. The purpose of our study was to evaluate the occurrence of histologically verified thyroid pathologies in women who were diagnosed with breast cancer and, after mastectomy/quadrantectomy complemented by oncological treatment, were thyroidectomized based on their periodic thyroid evaluation. Patients and Methods: Our series consist of 31 women with a mean age of 62.9 ± 10.9 years (range, 45–81) treated for breast cancer (18 right-sided, 11 left-sided, and 2 bilateral), of whom 29 were thyroidectomized, since two women who developed Graves’ disease refused thyroi…
Differential miRNA expression defines migration and reduced apoptosis in follicular thyroid carcinomas.
2013
The objective of the study was to identify microRNAs (miRs) characteristic for follicular thyroid carcinoma (FTC) and to define their role in tumorigenesis. A miR-microarray study was conducted to identify miRs differentially expressed between FTCs and their surrounding tissues. Selection was further reinforced by a literature review. Four miRs were selected and confirmed by RT-qPCR: miR-146b, -183, -221 were up-regulated, whereas miR-199b down-regulated in FTCs. The influence of these miRs on cell proliferation, cell cycle, apoptosis and migration was studied in HTori and FTC-133 cells. Functional characterization suggests an impact of miR-183 and miR-146b in FTC development. Overexpressio…
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…
Preliminary approach towards construction of peptide libraries as potential tools for diagnosis of malignant thyroid tumors
2006
Nowotwory złośliwe tarczycy należą do najczęstszych nowotworów złośliwych układu endokrynnego. Poprawa wyników leczenia wiąże się z postępem wczesnej diagnostyki raka. Celem niniejszych badań jest poszukiwanie wskaźników nowotworowych za pomocą bibliotek peptydowych umieszczonych na podłożu z bibuły. Materiał i metody: Analizie poddano tkanki pobrane od 6 pacjentów: 4 z rakiem brodawkowatym tarczycy, 1 z nowotworem pęcherzykowym oraz 1 pacjenta z rakiem oksyfilnym. Badania wykonywano z wykorzystaniem bibliotek peptydowych lipofilowych, porównując tkankę zdrową i chorą oraz oceniając zmianę zabarwienia w poszczególnych bibliotekach. Wyniki: Wstępne wyniki wskazują, że biblioteki peptydowe mo…
Safety of Tyrosine Kinase Inhibitors in Patients With Differentiated Thyroid Cancer: Real-World Use of Lenvatinib and Sorafenib in Korea
2019
Background: Thyroid cancer has become the most common cancer in Korea. Generally, thyroid cancer patients have a good prognosis; however, 15–20% of patients experience recurrence or distant metastasis or are refractory to standard treatment. We assessed the safety of sorafenib and lenvatinib in patients with advanced or metastatic radioactive iodine-refractory differentiated thyroid cancers (DTC) consecutively treated at a tertiary center in South Korea.Methods: We retrospectively reviewed the charts of all consecutive patients with DTC treated during ≥6 months with lenvatinib (February 2016–April 2018) and sorafenib (January 2014–April 2018) at Gangnam Severance Hospital. Patients were tre…
