Summary Objective: an attempt to determine the value of the simultaneous quantization of osteopontin (OPN), insulingrowth factor II (IGF II), leptin, prolactin and CA 125 for early detection of ovarian cancer Materials and methods: Prospective study of 69 women including: - 15 females with ovarian cancer - 33 females with benign ovarian neoplasm - 21 disease-free females The levels of IGF II, prolactin, leptin and CA 125 were determined in serum, while the level of OPN was checked in plasma. Results: The concentrations of IGF II, leptin and prolactin do not let us distinguish among disease-free females, females with ovarian cancer and those with benign ovarian neoplasms on the basis of biochemical markers. The comparison of OPN and CA 125 levels showed significant differences in the concentrations of the biomarkers between disease-free females and females with ovarian cancer, as well as between females with benign ovarian neoplasms and females with ovarian cancer. The ROC curves for two groups: disease-free females and females with ovarian cancer, proved the diagnostic value of OPN and CA 125. Conclusions: The simultaneous quantization of OPN, IGF II leptin and prolactin has not been proved useful for the early detection of ovarian cancer. Statistically significant increase of OPN & CA 125 levels was noted in case of women with ovarian cancer diagnosed through microscopic examination. The analysis of ROC curves showed comparable diagnostic usefulness of both markers. Quantization of OPN may have an additional value for treatment monitoring of women diagnosed with ovarian cancer but with concentration of CA 125 within the reference value.
