Objective: to evaluate the possibility of using cystatin С and TGF-p as prognostic markers of renal impairment and unfavorable oncological results of surgical treatment of renal cell carcinoma (RCC). Material and Methods. We examined 60 patients with RCC. Patients were divided into 3 groups: with RCC after nephrectomy (group 1); after laparo-scopic nephrectomy (group 2); after laparoscopic resection of the tumor (group 3). All patients before the operation on the 7th-10th day, after 1-3 years of postoperative follow-up, the concentrations of cystatin С and TGF-p in the blood serum were studied by solid-phase ELISA. Results. The majority of patients in the groups showed a significant decrease in glomerular filtration rate (GFR) compared to the control, and 3 years after nephrectomy, most patients had stage C3A chronic kidney disease (CKD). The Cystatin С content in all groups of patients with RCC had a statistically significant increase compared to the control (2664, 3103, and 2709 ng/ml in groups 1.2 and 3 versus 143 ng/ml, respectively) (p<0.05). Conclusion. In the majority of patients with RCC, postoperative initiation and progression of "surgical" CKD occurs, which persists 3 years after surgical treatment. Cystatin С can be considered as a predictor of high antitumor activity in patients with RCC, and requires monitoring in the long-term postoperative period.
