Study Summary

When used with a different radioactive tracer called FMISO, a PET scan can find areas of low oxygen in the tumor. We think that having areas of low oxygen is a reason why some tumors are hard to treat with radiation. In a past study, FMISO PET scans were performed in 6 patients with rectal cancer that could not be operated on and that had spread to other areas. In this group of patients, FMISO PET scans were able to find the low oxygen areas in their tumors. But this study included only a few patients. In the present study, we want to use FMISO PET scans in patients who have tumors that can be operated on. This group of patients will have radiation, chemotherapy or both before they have their surgery. We want to see if FMISO PET can find low oxygen areas in this distinct group of patients.

Primary Outcome

The uptake kinetics of \[18F\]-Fluoromisonidazole activity in the colorectal lesion was entered into a compartmental model to determine the rate constants of uptake (k1) and irreversible binding (k3) in the lesion on the PET scan at different times post injection. Also the tumor to background ratio was determine. A plot of k3 and TNB was plotted. This will help determine the Feasibility of a Non-invasive Method of Detecting Hypoxia, Using F-FMISO-PET Imaging in Colorectal Cancer Patients.
