| Popis: | The aim of the study was to assess the possibility of using plasma levels of tumor M2-pyruvate kinase (Tu M2-PK), matrix carbonic anhydrase IX (CA9), and matrix metalloproteinase 9 (MMP9) in patients with renal cell cancer as predictors of the disease course and the response to treatment. Materials and Methods Samples of blood plasma or serum of 46 patients with clear cell renal cancer T1–4N0–1M0–1 obtained before surgery and 8–9 days after surgery were tested. The control group consisted of 20 practically healthy individuals, comparable in age with the examined patients. Quantitative determination of Tu M2-PK in EDTA-added blood plasma was performed by enzyme-linked immunosorbent assay using a ScheBo Tumor M2-PK test (Germany). Determination of CA9 by ELISA was performed using a Human Carbonic Anhydrase IX Quantikine ELISA Kit (USA) and MMP9 — using a Quantikine ELISA Kit (USA). Results In patients with renal cell carcinoma, a statistically significant increase in the level of Tu M2-PK, CA9 and a statistically significant decrease in MMP9 in comparison with the control group were found. The level of Tu M2-PK in patients with localized kidney cancer was significantly lower than in patients with disseminated cancer. An increase in size of the primary tumor and a decrease in the degree of its differentiation correlated with an increase in Tu M2-PK, and decrease in CA9 and MMP9 in the blood serum. Performing surgery equivalent to nephrectomy did not change the Tu M2-PK levels in the early postoperative period, but caused a decrease in the levels of CA9 and MMP9. Conclusion The results indicate a potential significance of Tu M2-PK, CA9, and MMP9 as biological markers for predicting the disease course in patients with renal cell carcinoma. |
