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…
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…
Extramedullary hematopoiesis within endothelial papillary hyperplasia (Masson?s pseudoangiosarcoma) of the tongue
2007
We report the unique association of Masson?s pseudoangiosarcoma (endothelial papillary hyperplasia) and extramedullary hematopoiesis. The lesion was present as a violaceous nodule on the side of the tongue of a 78-year-old man with history of multiple myeloma and long-standing mild anemia. This association between a peculiar form of thrombus organization and extramedullary hematopoiesis has been reported previously only once, in an infant with a cranial hematoma, and raises interesting pathogenetic questions.
Bladder tumours in children: An interesting case report of TCC with a partial inverted growth pattern.
2014
Bladder urothelial carcinoma is typically a disease of older individuals and rarely occurs below the age of 40 years. There is debate and uncertainty in the literature regarding the clinicopathologic and prognostic characteristics of bladder urothelial neoplasms in younger patients compared with older patients, although no consistent age criteria have been used to define "younger" age group categories. We report on a 16 years old girl with transitional cell carcinoma of the bladder with a partial inverted growth pattern who presented with gross hematuria. Ultrasonography revealed a papillary lesion in the bladder; cystoscopic evaluation showed a 15 mm papillary lesion with a thick stalk loc…
