[The immunoscintigraphic diagnosis of the metastases of colorectal cancer by using monoclonal antibodies].
Sixty-four patients operated for colorectal cancer comprise the study group. CEA and CA-19.9 markers were used. The antibodies were labelled with 131I, using for the scintigraphy 99mTc as well. Eighty eight metastatic foci were detected, 67 of them (76.1 per cent) confirmed by the surgeon: Of 55 pelvic localizations, surgically detected were 47 (85.5 per cent), of 24 in the abdominal cavity 15 (62.5 per cent) were confirmed and of 9 in the liver--only 5 (55 per cent). Radioimmunoassay more accurate in pelvic localizations, whereas echography and computer tomography were more precise in liver examination (83.3 per cent).
