Increased plasma and salivary cortisol levels in patients with oral cancer and their association with clinical stage.

Objectives: Dysregulation of the hypothalamus-pituitary-adrenal axis has been observed in patients with cancer. This cross-sectional study investigated whether patients with oral and oropharyngeal squamous cell carcinoma (SCC) show changes in cortisol levels in saliva and plasma compared with three control groups, and evaluated its correlation with clinicopathological data.

Methods: Salivary and plasma cortisol levels of 34 patients with oral SCC were compared with hormonal levels of 17 oropharyngeal SCC patients, 17 oral leukoplakia patients, 27 smokers and/or drinkers and 25 healthy volunteers.

Oral rehabilitation after surgical removal of pleomorphic adenoma.

Although tumors of minor salivary glands are rare, the pleomorphic adenoma is the most common pathology among the benign neoplasm and can be found with high prevalence in the junction between hard palate and soft palate. The treatment of choice for most of maxillary tumors is surgical through either a total or partial maxillectomy. However, surgical defects caused by such type of treatment lead to both clinical and psychologic disorders for the patient.
