Acute phase reactants and circulating immune complexes in patients with ovarian carcinoma

Abstract

Serum levels of haptoglobin (HP), sialic acid total (NAN) and lipid-bound (NAL), seromucoid (SER), its content in total protein (%SER), as well as circulating immune complexes (CIC), were measured in sera of women with ovarian carcinoma, prior to their treatment and through the course of chemotherapy, remission and recurrence of malignancy, respectively. Control groups consisted of healthy women and patients with benign tumors (ovarian cysts and uterine myomas). Pretreatment measurements of acute phase reactants discriminated cancers (FIGO stages I+II, III, IV) from healthy group, however differences between benign tumors and stages of ovarian cancer were not so distinct. Changes in the examined parameters (acute phase reactants) indicated satisfactorily a response to the administered chemotherapy and early signs of the progression of the disease. Because of great variations in serum CIC concentrations, they were found to be of no value either in diagnosis or in the surveillance of the disease status.
