Parotid carcinoma is relatively rare in head and neck cancer, and its treatment is still controversial because of its diverse histology.<br>A total of 37 cases of parotid carcinoma were treated in our hospital between 1991 and 2005. In terms of the therapeutic strategy, patients with low-grade carcinoma were treated by surgery alone with preservation of the facial nerves, whereas those with high-grade carcinoma underwent surgery with facial nerve resection and full-dose radiotherapy.<br>We performed neck dissection in only N+ patients. The 5-year, cause-specific survival rate in the 37 patients with parotid carcinoma was 67.5%, being 76.0% for those with low-grade cancer and 58.0% for those with high-grade cancer. Our study suggests that more extensive surgery is required for those with high-grade malignancy in order to improve the 5-year survival rate.
