Study of Unilateral Neck Irradiation in Patients With SCC of the Head and Neck

Patients will be treated with definitive external beam radiation plus/minus chemotherapy plus/minus neck dissection in the ipsilateral neck (post radiation). The primary site will be treated with definitive radiation therapy, or definitive surgery plus post-operative radiation therapy. Primary endpoints are loco-regional control, as well as quality of life, xerostomia, mucositis, and neck fibrosis.

Salivary evaluations shall be performed prior to the initiation of radiation therapy, during the second week of EBRT, and at the completion of radiation. Evaluations will also be conducted at 3, 6, and 12 months after the completion of EBRT.

Oral mucositis will be assessed prior to the initiation of EBRT and weekly during EBRT. Evaluations will also be conducted at 3 and 6 months after the completion of EBRT. Two standardized mucositis scales will be used: the RTOG scale and the WHO scale.

Clinical response will be evaluated by physical exam and PET/CT. PET/CT scans will be done at 3, 6, 12, 18, and 24 months, and then when clinically indicated during follow-up.
