We have reviewed a 9-year experience with 47 patients treated for salivary tumors which arose In the parotid gland (23 patients; 48.9%), submandibular gland (15 Patients, 31.9%), minor salivary gland (8 patients; 17.0%), and sublingual gland (1 patient; 2.1%). The age of patients ranged from 12 to 71 with a mean of 42.9 years. The male to female ratio showed a female preponderance, 19:28 (1:1.5). An asymptomatic mass (91.5%) was most common presentation. With fine-needle aspiration, the predictive value of a neoplasm was 88.9%. Histopathologically, the most common salivary gland tumors was Pleomorphic adenoma(57.4%). The pleomorphic adenoma was most common in benign tumor group, and the mucoepidermoid carcinoma was most common in malignant tumor group. Of the salivary gland tumors, the incidence of cervical metastasis was 22.2%. Major postoperative complications were facial nerve paralysis and wound infection.

Background: Nasopharyngeal cancer is a rare disease with a relatively poor prognosis because it tends to be diagnosed at an advanced stage. The aim of this study was to establish the clinical characteristics of nasopharyngeal cancer. Materials and Methods: The medical records of 54 patients with nasopharyngeal cancer from January 1993 to December 2002 were reviewed retrospectively. Forty one cases were male (75.9%) and thirteen were female (24.1%). The average age was of 46.9 (range 16 to 78 years) years. The majority of patients (79.6%) were diagnosed in the advanced stage. The most common complaints were a neck mass (55.5%) and the WHO type III (53.7%) was the most frequent histological type. Results: The cumulative survival rate for a 5-year period was 46.5% and the T stage, N stage, pathologic type, and clinical stage were not significantly related to the survival rate. Sixteen of 54 (31.5%) cases presented with a distant metastasis of the bone, lung, brain, spine, and liver, and six cases (11.1%) presented with a locoregional recurrence. Conclusion: TNM staging is not appropriate for predicting survival rate of nasopharyngeal carcinoma patients. Therefore, a newer staging system, which includes new factors, is needed to predict the prognosis.
