Hypoxia Imaging for Esophageal Cancer to Guide Personalized Radiation Therapy

Prior to the start of study therapy, eligible subjects will receive a FMISO-PET scan. If there is uptake visualized on the scan, the tumor will be considered as hypoxic. If there is no uptake seen on the FMISO-PET scan, tumors will be labeled not hypoxic. Subjects with tumors identified by imaging as hypoxic will be treated with a higher dose of radiation therapy. Tumors will be defined as being hypoxic if FMISO accumulation occurs as demonstrated by standardized uptake value (SUV) uptake in the tumor.
