Twenty-two cases of ovarian cancer with operatively and histologically proven were studied by radioimmunoimaging (RID, using anti-CEA monoclonal antibody radiolabeled with 131I. Positive results were obtained in 20/22 of the ovarian cancer patients. No correlation between serum CEA and RII results was found. Forty-five of 48 metastatic lesions were localized with a positive rate of 93. 8%. Two ovarian cancer metastasis to omentum and one ovarian cancer metastasis to ascending colon were detected only by RII....

Eleven patients with breast cancer and 2 normal individuals were studied by radionuclide biological targeting technique with 131Ⅰ labelled monoclonal antibody C50. The imaging was recognized as Positive in 8 Patients and negative in 3 patients.In 7 of the eight positive patients the lymph nodes were proven pathologically to harbor metastatic foci and the eighth was found to contain CEA-antigen and antigen-antibody immunocomplexes in the lymphoid sinus by immunohistochemistry. No cancer cell was found histologically in the axillary lymph nodes of 3negative imaging gatients. As to the 2 normal controls imaging was negative.The results of this study not only demonstrated that the radionuclide biological targeting technique was useful in the diagnosis and localization of axillary lymph node metastases from breast cancer,but also indicated great clinical significance in surgery.

Results Among the 6 casesof negative imaging, MD was ruled out in 5 cases by operation and endoscopy(true negative), and confirmed by surgery and histology in one (false negative). Thirteen cases had active imaging. Of them, 12were proved to be MD and ectopic gastric mucosa(true opitive), and one was verfied as jejunal submucosavedar malformation. (false positive). The sensitivity, specificity and accuracy of radionuclide imagingwere found to be 92. 3 %, 83. 3 % and 89. 5 % respectively. Conclusions Pertechnetate abdominal scintigraphy is simple and easy. It should be the first choice of imaging diagnosis of MD.
