Study Overview
Brief Summary
RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
PURPOSE: This laboratory study is looking at DNA in tissue samples from patients with head and neck cancer.
Detailed Description
OBJECTIVES:
- Assess common genetic mutations in tumor and germline DNA samples from patients with head and neck squamous cell carcinoma (HNSCC).
- Search for viral DNAs and relate this information to demographics, tumor characteristics, and patient prognosis.
- Search for novel viral sequences and cancer-associated gene mutations in young nonsmoking HNSCC patients and in other distinct head and neck cancers.
- Determine tumor suppressor gene mutations in HNSCC patients and relate this information to gene expression data.
- Validate gene expression information using independent techniques such as real-time PCR on expressed sequences and immunohistochemistry.
OUTLINE: Genetic mutation analysis and gene expression studies are performed on tissue samples from patients with head and neck squamous cell carcinoma. Techniques used include real time-PCR and immunohistochemistry.
