ABSTRACT
In a first, retrospective study, 15 patients with known ovarian carcinoma were injected with 131I-OC 125 F(ab')2 monoclonal antibody (MAb). The sensitivity of immunoscintigraphy based on the number of the tumor sites was 67% (12/18). In a second, prospective study, 29 patients with gynecologic carcinoma were injected with 131I-OC 125 F(ab')2 (24) or 131I-19-9 F(ab')2 (5) MAbs according to the histologic type. Based on the number of tested anatomic sites, sensitivity was 72% and specificity 86%. In two patients injected with both 131I-OC-125 F(ab')2 and 125I-NS F(ab')2 (nonspecific immunoglobulin) 1 and 4 days before tumor resection, tumor uptake of the specific antibody was 2.2 and 4.5 times greater than that of NS. Immunoscintigraphic results were complementary with those of ultrasonography and computed tomography. Finally, in one patient injected successively with 131I-OC 125 F(ab')2 and 111In-DTPA-OC 125 F(ab')2, the recurrent tumor was visualized with both radionuclides, with 111In providing better abdominal tumor contrast but causing much greater liver radioactivity than 131I.
