Variation in Selected Chemical Element Contents Associated with Malignant Tumors of Human Thyroid Gland

Unusual malignant tumors of the thyroid gland.

BACKGROUND Although situated on the last places among the statistical hierarchy of human malignancies, thyroid cancers (TC) are the most common tumors of the endocrine system. Follicular epithelium neoplasms account for more than 90% of these lesions with a favourable prognosis, while resting tumors (medullary, anaplastic, lymphoma, sarcoma etc) generally present a rapid unfavorable evolution w...

MTA1 Expression in Benign and Malignant Salivary gland Tumors

Introduction: Salivary gland tumors (SGTs) are important parts of human neoplasms. The most common SGT is pleomorphic adenoma and the most common malignant SGTs are mucoepidermoid carcinoma and adenoid cystic carcinoma (ACC). Metastasis-associated genes 1 (MTA1), a member of the nucleosome remodeling and histone deacetylation complex, is one newly discovered gene which recruits histone deacetyl...

Neoangiogenesis in Benign and Malignant Salivary Gland Tumors

Introduction: There are few studies investigating the role of neoangiogenesis in biological behavior of salivary gland tumors. CD105 expression has demonstrated greater accuracy for detecting new vessel formation compared with other pan-endothelial molecules. This study aimed to assess and compare intratumoral Micro-Vessel Density (MVD) through using immunohistochemichal expression of CD105 bio...

Serum Levels of Cyfra 21 in Patients with Benign and Malignant Salivary Gland Tumors

Introduction: Cyfra 21 is a serum-soluble fragment of cytokeratin19. Increased Cyfra 21 serum levels and their benefit as a tumor marker have been shown in some malignancies. This study aimed to evaluate the serum levels of Cyfra 21 in patients with benign and malignant salivary gland tumors. Materials and Methods: In this cross-sectional study, the serum level of Cyfra 21 in 44 patients with m...
