Tumour markers with unknown functions in gynaecological neoplasia

Pre- and post-operative ovarian cancer patients' sera were examined for the presence or circulating immune complexes using a variety of assay procedures. In contrast to findings with breast cancer patients' sera, sera from patients with other gynaecological tumours or with preclinical disease diagnosed by cytology, no evidence was obtained to indicate that circulating immune complexes were associated with ovarian cancer.
