The parotid gland carcinoma is an infrequent tumor, which has various histological characteristics.
In the 20-years from 1993 to 2012, we treated 42 subjects with parotid gland carcinoma. Twenty-nine patients (69.0%) were male, and 13 patients (31.0%) were female. The mean patient age was 62.3 years, ranging from 19 to 91 years. In pathological analysis, the histological diagnoses were as follows: mucoepidermoid carcinomas in 11 patients (26.2%), salivary duct carcinomas in 11 (26.2%), acinic cell carcinomas in 6 (14.3%), adenoid cystic carcinomas in 3 (7.1%), and 2 (4.8%) with squamous cell carcinomas and basal cell carcinomas, and low-grade cribriform cystadenocarcinoma. Only two cases undergoing fine-needle aspiration biopsy were preoperatively diagnosed as having the exact pathology. The local control depend upon the pathological grade of the tumor. The 5-year and 10-year survival rates were 60.3% and 25.8%, respectively, with Kaplan-Meier analysis. The main finding of this study was that radical resection is a reasonable approach and postoperative radiotherapy is helpful for parotid gland carcinomas of the head and neck.
