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

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.

PROCEDURE

Eppendorf hypoximeter

Patients consented to the protocol will proceed to their surgery date without any change in the standard preoperative period. After arriving in the operating room, the patient will undergo intravenous general anesthesia (or spinal/epidural anesthesia) by the anesthesiologist and will receive 40% oxygen. At this time, the principal investigator (along with the assistance of the operating surgeon and a member of the Department of Medical Physics) will use the Eppendorf hypoximeter to gather pO2 measurements. We anticipate that this will add no more than fifteen minutes to the planned procedure. Once the measurements are collected, the anesthesia will be adjusted as appropriate for the surgery and the procedure will continue as usual.
