Characterization of Rectal Cancer Hypoxia Using pO2 Histography and Immunohistochemistry for Hypoxia-Related Proteins

Not Applicable
Completed
Conditions
Rectal Cancer
Registration Number
NCT01189877
Lead Sponsor
Memorial Sloan Kettering Cancer Center
Brief Summary

The purpose of this study is to see if the cells in rectal cancer are oxygen-starved, or hypoxic. We know that as cancers grow bigger, parts of them are cut off from the oxygen supply and they become hypoxic, basically, lacking oxygen. Research has shown that cells that are oxygen-starved respond differently to treatment such as chemotherapy and radiation when compared to cells that are oxygen rich.
