Brief Summary: The goal of this study is to learn how tumors of the upper airway and digestive passages tongue throat mouth and voicebox affect the bodys immune defenses and energy storage

Previous studies have shown that tumors of the vocal tract produce signals that could help the tumor escape the bodys immune defenses and use the bodys energy and mineral stores to grow

Researchers are hoping to learn more about what signals give tumor cells an advantage to live and grow how tumor cells control these signals and how these signals affect the rest of the body This study will look closer at researchers belief that tumors in the vocal tract contain genes genetic information that abnormally function to allow the tumors to survive and grow against the attack of the bodys normal immune system

Patients with cancerous tumors squamous cell carcinoma and benign non-cancerous tumors papilloma of the upper aerodigestive tract who are candidates for standard or investigational therapy are eligible to participate in this study

Tumor cells will be collected from patients participating in the study who will undergo standard surgical treatment or biopsies for their conditions Once tumor cells are collected they can be analyzed for their genetic make-up

In addition patients will undergo several tests using skin blood and urine to look closely at the function of their immune systems and metabolism
Detailed Description: Patients with squamous cell carcinoma or papilloma of the upper aerodigestive tract who are candidates for standard or investigational therapy are eligible to participate in this pilot immunopathogenesis study Patients with these neoplasms exhibit alterations in immune and metabolic regulation These alterations in immunoregulation have been shown to affect prognosis and have thus far been an obstacle to the successful development of active immunization and cytokine immunotherapy that have been attempted in order to improve preservation of organ function and survival This is a pilot study to explore the basis for alterations in immune and metabolic regulation in patients with these tumors Similar alterations in immunity and metabolism usually occur in response to injury and infection and are mediated by expression of immunoregulatory signals The study will evaluate the hypothesis that regulatory and structural genes involved in immunoregulation are abnormally expressed within the tumor and that these signals can promote tumor development and progression by conferring a selective growth or survival advantage The expression and activity of immunoregulatory genes and signals which are expressed by neoplastic or non-neoplastic cells within the tumor will be analyzed using tumor cells and leukocytes derived from patient specimens obtained during clinically indicated biopsies or surgical therapy Tumor and keratinocyte cell lines will be established for analysis of differential gene and cytokine expression of neoplastic cells and lymphocyte cell lines will be established to test culture and signal conditions for stimulating regulatory and effector immune responses of patient lymphocytes in vitro The potential of factors identified to promote altered immune and metabolic function will be evaluated in the patients by skin blood and urine immune and metabolic assays performed before and after tumor resection or cytoreduction Patients participating in these investigations would be expected to benefit from receipt of standard therapy and would encumber minimal additional risk beyond those procedures for the standard or investigational therapy for which the patient will be asked to consent Twenty patients each with squamous cell carcinoma and papilloma will be accepted to undergo standard therapy under this protocol and twenty patients may be accepted for study while undergoing therapy on other approved investigational protocols Twenty age-matched clinical research volunteers will be evaluated as control subjects for the skin blood and urine tests
