title: Clinical trials with fluorinated pyrimidines in patients with head and neck cancer.
abstract: While it is estimated to be one of the most prevalent cancers in the world, cancer of the head and neck is an uncommon malignant tumor in the United States and accounts for only 5% of all malignancies. Head and neck cancer is a term that encompasses heterogeneous groups of patients. The most common histologic type is the squamous cell carcinoma. Cancer of the oral cavity is the most common site among the head and neck tumors. The majority of patients (70-80%) present with locally advanced (Stage III and IV) cancer. The standard treatments of surgery and/or radiotherapy have a high cure rate for patients with early disease (Stages I or II), but not for patients with locally advanced tumors. Local recurrence and persistent disease occur in more than 60% of patients present with advanced cancer, and approximately 10%-20% of all patients develop distant metastases. Chemotherapy is usually used for palliation in patients with recurrent and metastatic head and neck cancer at which time these patients have failed the definitive therapy of surgery and/or radiotherapy and the chances for salvage is almost nil. With the identification of more active cytotoxic agent(s) and combinations, chemotherapy is being investigated as part of multi-modality treatment in patients with previously untreated and locally advanced head and neck cancer.
