Monitoring of chemotherapy successfulness of platina/taxol chemotherapy protocol by using determination of serum urokinase plasminogen activator (uPA) and soluble urokinase plasminogen activator receptor (suPAR) in patients with ovarian carcinoma FIGO II and III stage.
In about 70% of cases, ovarian carcinoma has been diagnosed at an advanced stage. Invasion and metastasis of solid tumors request protease activity resulting in basal membrane destruction and surrounding matrix. In that process, urokinase plasminogen activator (uPA) and its receptor, urokinase plasminogen activator receptor (suPAR) play a key role, that via plasmin activation lead to basal membrane and matrix degradation in surrounding of the tumor, enable to its invasion and metastasis. ⋯ Serum levels of uPA and suPAR have been determined by ELISA-test (Imubind uPA, Imubind uPAR, American Diagnostica), and CEA by OPUS Imunoassay method. Results of this study have shown that uPA, suPAR and CEA met criteria for prognostic markers for monitoring of successfulness of platina/taxol chemotherapy protocol for serous, mucinous and clear cell tumor FIGO II and III stage of ovarian carcinoma. In case of PT chemotherapy protocol suPAR was better prognostic marker for monitoring of chemotherapy successfulness (Pearson coefficient 0,9 do 1,0; p<0,00l) than uPA (Pearson coefficient between 0,86 and 0,92; p<0,02) and CEA (Pearson coefficient 0,5 do 0,89; p<0,04).
