Fludeoxyglucose F 18 (FDG) is injected intravenously over 2 min. Initial dynamic images will be obtained over the heart. Emission imaging will work from the midcervical region down to the perineal region.\n\nFor CEA scanning, radiolabeled antibody, arcitumomab (IMMU-4), is injected intravenously over 5 min. A single photon emission computed tomography (SPECT) transmission scan is performed over the same regions as the emission scans. Total dose from transmission scans should be no more than 20 mRad per patient visit.\n\nPatients then undergo exploratory laparotomy performed by two surgeons, one blinded to the results of the CEA-Scan and PET scan.\n\nAt the completion of all exploration, all identified disease is biopsied for pathologic analysis and any resectable disease is removed.\n\nPatients are followed every 3 months for 1 year, every 6 months for the second year, and then after 3 years.", "DetailedDescription"=>"Recurrences following resection for colorectal carcinoma occur in 50% of patients. Early detection and management of recurrences results in improved survival. Post-operative surveillance consists of serial CT scans, chest x-rays, colonoscopy and CEA determinations. Elevations in the serum CEA level can be the earliest and most sensitive indicator of recurrence. A rise in the serum CEA level in the absence of imageable disease presents a particular diagnostic challenge. Advanced imaging modalities such as Positron Emission Tomography (PET) and anti-CEA antibody immunoscintigraphy have been proposed as a way of localizing disease in these patients. This study will evaluate the sensitivity, specificity, accuracy and predictive value of FDG-PET scans and anti-CEA immunoscintigraphy in patients following resection of colorectal carcinoma who have rising serum CEA values in the absence of imageable disease by conventional modalities. Patients who meet inclusion criteria will undergo FDG-PET scan and anti-CEA immunoscintigraphy followed by an exploratory laparotomy. Abdominal explorations will be conducted by two surgeons, one of whom will be blinded to the results of the FDG-PET and CEA scans. All suspicious lesions will be biopsied and if possible resected. Results at operation will be correlated with the results of the scans. The goal of the study is to determine the role of FDG-PET scanning and anti-CEA immunoscintigraphy in the localization of recurrent colorectal carcinoma in patients with rising serum CEA levels."}, "EligibilityModule"=>{"Gender"=>"All", "StdAgeList"=>{"StdAge"=>["Child", "Adult", "Older Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"All patients greater than 18 years old who have had a prior resection of colorectal cancer and are suspected of having recurrent disease.\n\nRising serum CEA levels greater than 6 on two successive tests.\n\nResectable residual or recurrent disease.
