Abstract

Eight colorectal and 5 ovarian cancer patients were evaluated with preoperative immunoscintigraphy and intraoperative gamma probe detection of 111indium-labeled monoclonal antibody B72.3. Immunoscintigraphy detected the presence of tumor in every patient shown to have tumor at surgery. There was one false-positive scan. A total of 21 pathologically verified lesions were identified at surgery in the 11 patients with tumor. Immunoscintigraphy localized 12 (57%) and intraoperative gamma probe detection located 17 (81%) of the lesions. Intraoperative probe detection located 6 of 8 lesions smaller than 1 cm and 3 lesions that were not identified on initial surgical exploration. The gamma probe offers information that is complementary to immunoscintigraphy in that (1) it aids the surgeon in locating intra- and extra-abdominal lesions previously identified by immunoscintigraphy, (2) it locates lesions too small to be seen by immunoscintigraphy alone, (3) it locates lesions that otherwise might be missed at surgery, and (4) it provides objective evidence for adequacy of surgical resection of cancer in the abdominal cavity.
