Abstract
IGF-I, II, IGFBP-1, 2 and 3 levels were measured with standard ELISA kits (Mediagnost) in blood serum of 44 ovarian cancer, 12 benign and 11 borderline ovarian tumorpatients. Control group comprised 33 practically healthy women. Serum IGF-1 content in ovarian cancer patients was significantly lower, and IGFBP-1 content - higher than in all other groups. IGFBP-2 level was increased both in ovarian cancer and borderline tumor groups as compared to control and benign ovarian tumor patients. No significant associations were found between the majority ofparameters studied and main clinico-pathologic characteristics of ovarian cancer. Thus, disturbances in IGFs/IGBPs balance were revealed in blood serum of ovarian cancer patients, and IGFBP-2 proved to be a potential diagnostic serological marker with 90% specificity and 90% sensitivity.
