The standard treatment for cancer of the salivary gland is surgery. Although surgery may have removed the cancer, some patients are at increased risk for recurrence. In these patients, radiation therapy after surgery is recommended.
The purpose of this study is to see if giving chemotherapy in addition to radiation after surgery is more effective than radiation alone in patients with high-risk salivary gland tumors. Patients will be randomly assigned to receive radiation after surgery or radiation plus the anticancer drug cisplatin, given concurrently.
