[Immunoscintigraphy and intraoperative tumor search in ovarian cancer].

The diagnostic possibilities of immunoscintigraphy (IS) in ovarian cancer are discussed. Seventy-five patients were investigated by IS using the radioantibodies HMFG-2 (n = 63) or OC-125 (n = 12). The results showed a specificity of 75%, sensitivity of 87%, and accuracy of 84%. An intraoperatively usable gamma ray detection probe was developed in order to achieve better results than with conventional IS. Twelve patients were investigated using this probe. A future clinical value was indicated for intraoperative detection of lymphnode metastases and/or small tumor deposits.
