Head and neck cancer patients treated by radiation commonly suffer from a devastating side effect known as dry-mouth syndrome, which results from the irreversible loss of salivary gland function via mechanisms that are not completely understood. In this study, we used a mouse model of radiation-induced salivary hypofunction to investigate the outcomes of DNA damage in the head and neck region. ...
mucoepidermoid carcinoma is a neoplasm of salivary gland origin, and its laryngeal occurrence is extremely rare. this malignant tumor is composed of two distinct cell types, the epidermoid and mucus cells. prognosis is largely dependent on the histologic pattern. in this report, an extremely rare laryngeal cancer and its clinicopathologic features are described.
BACKGROUND Radiation is a primary or secondary therapeutic modality for treatment of head and neck cancer. A common side effect of irradiation to the neck and neck region is xerostomia caused by salivary gland dysfunction. Approximately 40,000 new cases of xerostomia result from radiation treatment in the United States each year. The ensuing salivary gland hypofunction results in significant mo...
Malignant salivary gland tumors represent a particular challenge in diagnostics due to their large number of histopathological entities, rare occurrence and diversity clinical histological presentation. The aim our work is investigate the usefulness provide comparison convolutional-neuronal networks (CNNs) as diagnostic tool diagnosis cancer.
Introduction: In this study the automatic separation of oral and salivary gland activity and spontaneous secretion by means of factor analysis for quantitative salivary gland scintigraphy is introduced. Methods: After intravenous administration of 99mTc sodium pertechnetate, dynamic scintigraphy was performed. 20 minutes after tracer application 2 ml of lemon juice was delivered to stimulate t...
Salivary gland tumors accounts for less than 1% of all tumors. Minor salivary gland tumors (MSGTs) are uncommon and make up about 10% of all salivary gland neoplasms. The clinical and histopathological distribution of these tumors vary geographically. A case of a 38 yr old man with a minor salivary gland mass at chin region isreported here. The tumor invaded into the anterior ...
introduction: the use of radioactive iodine (131i) has become an important adjunct to the treatment of thyroid cancer and hyperthyroidism. salivary gland has the ability to concentrate radioactive iodine under normal circumstances. salivary gland dysfunction and dry mouth are the common side effectsof high-dose radioiodine therapy. the purposeof this study was to determine the absorbed dose of...
introduction: malignant salivary gland tumors are rare entities. despite advances in surgery, radiation therapy and chemotherapy, the rate of the mortality and five-year survival has not been improved markedly over the last few decades. the activation of egfr- ras-raf signaling pathway contributes to the initiation and progression of many human cancers, promising a key pathway for therapeutic m...
a case of pleomorphic adenoma in sweat gland is reported here. the histopathologic report confirmed the diagnosis. pleomorphic adenoma is most common in salivary glands but very rare in sweat glands. pleomorphic adenoma in sweat gland and the similar tumors of eccring sweat gland are described that bear a striking resemblance to pleomorphic adenomas of salivary gland. upon closer examination, t...
OBJECTIVE In the current study, we examined whether selenium supplementation during iodine-131 (131I) treatment had a radio-protective effect on salivary glands. SUBJECTS AND METHODS Sixteen patients with differentiated thyroid cancer were prospectively enrolled in the study. Patients after total thyroidectomy, before 131I treatment, were divided into two groups; 8 patients in the selenium gr...
