| Abstract: | The clinical usefulness of a I-131 anti CEA F(ab')2 MoAB and CA 19-9 F(ab')2 MoAB cocktail(IMACIS-1) for the localization of a cancer has been studied in 35 patients (Lung Ca. 10, Pancreas Ca. 7, Gastric Ca. 6, Colon Ca. 5, Hepatoma 2, Cholangio Ca. 2, Esophageal Ca. 1, Uterus Ca. 1, and, Retroperitoneal tumor 1). Of these 28 patients (80%) had an abnormal accumulation of radioactivity in the tumor sites (Lung Ca. 5, Pancreas Ca. 7, Gastric Ca. 6, Colon Ca. 5, Hepatoma 2, Esophageal Ca. 1, Uterus Ca. 1, and, Retroperitoneal tumor 1). Eighteen cases (56.3%) in 32 cases in which the primary site was known showed an abnormal radioactive accumulation and, similarly, 20 metastatic sites (71.4%) in 16 cases with 28 metastatic sites also showed an abnormal accumulation of radioimmunoscintigraphy showed no correlation with the serum CEA or CA 19-9 concentration. Further, no side effect was observed. |
