STATEMENT OF THE PROBLEM Matrix metalloproteinases (MMPs) have been implicated in the pathogenesis of certain diseases and cancers via tissue destruction and can be secreted into the blood stream. MMP9 expression in the salivary gland tissue was evaluated but their serum level in the salivary gland tumors was not studied. PURPOSE The aim of our study was to determine the concentration of seru...
BACKGROUND AND AIMS Salivary gland tumors are rare and specific lesions. There are differences in the incidence and frequency of salivary tumors in both minor and major salivary glands in different countries. This study was carried out to determine the prevalence of major and minor salivary gland tumors in Ahvaz in the south of Iran. MATERIALS AND METHODS All the cases, recorded in Imam Khome...
AIM To evaluate the types and clinical outcome of salivary gland tumors in Jordan. METHODS Hospital records of 221 patients (85 women and 136 men) with salivary gland tumors, diagnosed from January 1988 to December 1997 were reviewed. The patients were analyzed according to sex, age, histopathological type and site of the tumor. Survival curves for patients with malignant tumors were construc...
Salivary gland neoplasms are a rare group of tumors; the annual incidence rate is 1 in 100,000 individual, comprising about 3% of all head and neck neoplasms [4]. The mean age of patients with salivary gland tumors is 45 years, peaking in the sixth and seventh decades of life. Benign salivary gland tumors occur more frequently in females, while malignant tumors are slightly more frequent in mal...
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 deacetyla...
This article discusses salivary gland disorders and provides nurses with a broad base of knowledge for use in planning and implementing perioperative patient care. Salivary gland disorders may be caused by nonneoplastic conditions or neoplasms. Nonneoplastic conditions generally are related to inflammatory processes or are secondary to existing disease processes. Neoplasms manifest themselves a...
OBJECTIVES To determine the expression level of the Wnt components-WIF1 (Wnt inhibitory factor 1), WNT1, and beta-catenin-in salivary gland tumor cells and to investigate the mechanisms that contribute to activation of the Wnt pathway in human salivary gland tumors. DESIGN The expression of WIF1, WNT1, and beta-catenin in salivary gland normal tissue and tumor cell lines was analyzed by rever...
Pleomorphic adenoma also known as “mixed tumor” is the most common neoplasm in major salivary glands. It is a benign tumor arises from the parotid gland in 84% of cases and represents 45% of parotid gland tumors [1]. Only 6.5% are found in the minor salivary glands [2]. Salivary gland tumors occurring in ectopic sites are rare and poorly understood; sometime we can find heterotopic tissue arisi...
Salivary gland tumors are relatively uncommon and account for approximately 3-6% of all neoplasms of the head and neck. Tumors mostly involve the major salivary glands, 42.9-90% of which occur in the parotid glands and 8-19.5% in the sub-mandibular glands; tumors in the sub-lingual glands being uncommon. Despite the plethora of different malignant salivary gland tumor presented to pathologists ...
Purpose: It has been reported that diffusion-weighted imaging (DWI) might be useful for characterizing head and neck tumors, suggesting that malignant tumors have a lower apparent diffusion coefficient (ADC) than benign tumors. However, it remains uncertain if ADC is useful for distinguishing between benign and malignant salivary gland tumors. This study was intended to evaluate the ADC of beni...
