Radiation Therapy With or Without Cisplatin in Treating Patients With Advanced Head and Neck Cancer

Phase III Study of Hyperfractionated Radiation Therapy With or Without Simultaneaous Application of CIS-Platinum in Patients With Moderately Advanced to Advanced Cancers of the Head and Neck

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if radiation therapy plus chemotherapy is more effective than radiation therapy alone in treating patients with advanced head and neck cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy plus cisplatin with radiation therapy alone in treating patients with advanced head and neck cancer.

OBJECTIVES: I. Assess the time to treatment failure (local and regional) in patients with moderately advanced and advanced squamous cell carcinoma of the head and neck (no distant metastases) when treated with hyperfractionated radiotherapy with vs. without 2 courses of simultaneously administered cisplatin. II. Assess the time to distant metastatic relapse, overall survival, and toxicity in patients receiving these treatments. III. Evaluate whether the potential tumor-doubling time is an indicator for risk of treatment failure in patients receiving these treatments. OUTLINE: Randomized study. Arm I: Radiotherapy plus Single-Agent Chemotherapy followed, as indicated, by Surgery. Hyperfractionated external-beam tumor irradiation using photon energies of 4-6 MV or electrons of 6-12 MV (interstitial brachytherapy boost to lesions of the oral cavity allowed); plus Cisplatin, CDDP, NSC-119875; followed, in patients with persistent disease (at the discretion of the surgeon), by resection of primary tumor or involved nodes. Arm II: Hyperfractionated radiotherapy followed by Surgery. Tumor irradiation as in Arm I; followed by resection as in Arm I. PROJECTED ACCRUAL: At least 400 patients will be accrued over 5 years. Interim analyses to allow for early stopping will be carried out after entry of 50 and 100 patients.
