RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining more than one chemotherapy drug with radiation therapy may kill more tumor cells.
OBJECTIVES: I. Assess the feasibility of the administration of ethynyluracil concurrently with fluorouracil and radiotherapy in patients with advanced oral cancer. II. Determine the maximum tolerated dose (MTD) and dose-limiting toxicities of this regimen in this patient population.
OUTLINE: This is a dose escalation study of fluorouracil and hydroxyurea. Patients receive oral ethynyluracil every 12 hours on days 1-7 and oral fluorouracil every 12 hours on days 2-6. Radiotherapy to the head and neck is administered twice daily on days 2-6. Treatment continues for 5-7 courses in the absence of unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of fluorouracil until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 3 of 6 patients experience dose limiting toxicities. Once the MTD of fluorouracil is determined, hydroxyurea is added to the treatment regimen. Patients receive fluorouracil and ethynyluracil as per the treatment schedule outlined above. Patients also receive oral hydroxyurea every 12 hours for 11 doses on days 1-6. Radiotherapy is administered as above. Cohorts of 3-6 patients receive escalating doses of hydroxyurea until the MTD is determined. Once the MTD of fluorouracil and hydroxyurea are determined, an additional 10 patients receive Phase II doses of ethynyluracil, fluorouracil and hydroxyurea as per the treatment schedule outlined above. Treatment continues in the absence of unacceptable toxicity. Patients are followed at 4-6 weeks, then every 6 months until death.
PROJECTED ACCRUAL: Approximately 40 patients will be accrued for this study over 2 years.

Postoperative chemoradiotherapy (CRT) is considered standard of care in patients with locally advanced head and neck cancer with positive margins and/or extracapsular extension (ECE).
Radiation therapy for head and neck malignancies has made remarkable advances in treatment technology, resulting in improved clinical and functional outcomes. It is necessary for the radiation oncolog...
Soft tissue tumors or cancer arising from the mucosal surfaces of the LIP; oral cavity; PHARYNX; LARYNX; and cervical esophagus. Other sites included are the NOSE and PARANASAL SINUSES; SALIVARY GLANDS; THYROID GLAND and PARATHYROID GLANDS; and MELANOMA and non-melanoma skin cancers of the head and neck.

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
A form of RHABDOMYOSARCOMA arising primarily in the head and neck, especially the orbit, of children below the age of 10. The cells are smaller than those of other rhabdomyosarcomas and are of two basic cell types: spindle cells and round cells. This cancer is highly sensitive to chemotherapy and has a high cure rate with multi-modality therapy. (From Holland et al., Cancer Medicine, 3d ed, p2188)
A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.
Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.

Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
