NCT01302834
Radiation Therapy With Cisplatin or Cetuximab in Treating Patients With Oropharyngeal Cancer
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether radiation therapy is more effective with cisplatin or cetuximab in treating oropharyngeal cancer. PURPOSE: This phase III trial is studying radiation therapy with cisplatin or cetuximab to see how well it works in treating patients with oropharyngeal cancer.

Gastrointestinal Biomarkers in Tissue and Biological Fluid Samples From Colorectal Cancer Patients
RATIONALE: Studying samples of tissue, blood, urine, stool, and other biological fluids from patients with cancer and from healthy volunteers undergoing colonoscopy or endoscopy may help doctors identify and learn more about biomarkers related to cancer. PURPOSE: This research study is looking at gastrointestinal biomarkers in tissue and biological fluid samples from patients and participants undergoing colonoscopy, endoscopy, or surgery.

Biomarkers in Patients With Respiratory Tract Dysplasia or Lung Cancer, Head and Neck Cancer, or Aerodigestive Tract Cancer and in Normal Volunteers
RATIONALE: Studying samples of sputum and tissue in the laboratory from patients with dysplasia or cancer may help doctors identify and learn more about biomarkers related to cancer. It may also help the study of cancer in the future. PURPOSE: This laboratory study is looking at biomarkers in patients with respiratory tract dysplasia or lung cancer, head and neck cancer, or aerodigestive tract cancer.
