Summary
The purpose of this study is to identify and confirm new blood and tissue markers for prognosis and tumor hypoxia. Tumor hypoxia, or the condition of low oxygen in the tumor, has been shown to increase the risk of tumor spread and enhance tumor resistance to the standard treatment of radiation and chemotherapy in head and neck and lung cancers. We have recently identified several proteins or markers in the blood and in tumors (including osteopontin, lysyl oxidase, macrophage inhibiting factor and proteomic technology) in the laboratory that may be able to identify tumors with low oxygen levels or more aggressive behaving tumors.
Detailed description
The endpoints of the study are 1. To validate the prognostic significance of OPN in H\&N and lung cancer patients and to monitor its level during active therapy and follow up for cancer surveillance. 2. To identify a gene and protein signature for hypoxia in H\&N and lung cancer patients.
Conditions
Interventions
| Type | Name | Description |
|---|---|---|
| PROCEDURE | Tumor biopsy | For patients who undergo tumor biopsy or resection at Stanford, approximately 500 mg of the tumor will be removed from the resection specimen |
| PROCEDURE | Phlebotomy | Blood draw (approximately 20 cc) prior to any anticancer therapy Weekly blood draw (approximately 20cc) only for patients who are undergoing radiation treatment at Stanford University |
