Carcinoma of the parotid gland.

Sixty-nine patients with parotid gland cancer were studied at the Cancer Control Agency of British Columbia; half were treated successfully. Localized cancers should be treated by total parotidectomy with facial nerve preservation. Facial nerve sacrifice and radical neck dissection for metastatic lymph nodes may be required. If adequate surgery has been done, the histologic type of the tumor significantly determines the outcome. Postoperative radiation to the parotid bed in the more malignant types of tumor is advocated and appears to improve the results of treatment.
