Cancer of Head and Neck

Brief summary
The purpose of this study is to determine if soy supplementation during chemotherapy and radiation therapy will decrease side effects caused by treatment. Long-lasting dry mouth is a side effect of the standard treatment, and we are testing whether soy supplementation during treatment may reduce this symptom and other side effects of chemoradiation.
Detailed description
Concurrent chemoradiation is the standard of care for locally advanced squamous cell carcinoma of the head and neck (SCCHN). Improving the outcome for patients with this disease remains a major challenge.
Interventions
Patients will receive genistein 150 mg daily for the duration of radiation treatment. If a patient is experiencing significant side effects attributable to genistein, the treating physician has the option to reduce genistein to 150 mg every other day.
All patients will undergo computed tomography (CT) simulation with intravenous (IV) contrast unless medical contraindications to IV contrast exist. Gross disease will be treated to 70 Gy in 2 Gy/day.
Cisplatin chemotherapy 100 mg/m² on days 1, 22, and 43 of radiation treatment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of patients with grade 2 or higher xerostomia at 1 year post-treatment | 1 year after treatment completion | The primary outcome of this study is the percentage of patients with symptomatic (grade 2 or higher) xerostomia at 1 year post-treatment, assessed by the Late Effects of Normal Tissues (LENT)/Subjective, Objective, Management, Analytic (SOMA) method. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Exploratory biomarker studies: changes in interleukin 6 | 3 and 6 months post-treatment | Serum baseline levels of interleukin 6 (IL6) and their levels at 3 and 6 months post-treatment. |
| Exploratory biomarker studies: changes in vascular endothelial growth factor | 3 and 6 months post-treatment | Serum baseline levels of vascular endothelial growth factor (VEGF) and their levels at 3 and 6 months post-treatment. |
| Exploratory biomarker studies: changes in isoprostanes levels | 3 and 6 months post-treatment | Baseline urinary levels of isoprostanes before treatment, and 3 and 6 months post-treatment, as a potential marker of oxidative stress associated with chemoradiation. |
