    Abstract:
    UNLABELLED: OBJECTIVE. Tumour markers are widely used for monitoring cancer patients and for screening certain tumours. It has recently been shown that the concentrations of some tumour markers are higher in patients with chronic kidney disease (CKD) than in healthy subjects. We analysed the influence of renal function and hemodialysis treatment on the serum levels of CA19-9, CA125, alpha fetoprotein (AFP), CA15.3, CA72.4, CYFRA 21-1, neuron-specific enolase (NSE) and squamous cell carcinoma antigen (SCC-Ag). MATERIAL AND METHODS: 232 non-dialysis patients with CKD and 37 uraemic patients treated with maintenance hemodialysis were enrolled in this study. The nondialysis patients were divided into three groups depending on their creatinine clearance (Ccr) levels: group 1 = Ccr < or =25 mL/min; group 2 = 25.1-49.9 mL/min; group 3 = Ccr > or =50 mL/min. For comparison, we chose 37 non-dialysis patients with similar Ccr, age and same gender as controls. RESULTS: The serum concentrations of CA19-9, CA125 (male), CYFRA 21-1, NSE and SCC-Ag correlated negatively with Ccr, while there were no significant differences in the concentrations of CA125 (female), AFP, CA15.3, CA72.4. The serum levels of CA19-9, CA125, AFP, CA15.3, CA72.4, CYFRA 21-1, NSE and SCC-Ag showed no differences between hemodialysis patients and non-dialysis controls (p > 0.017). CONCLUSIONS: The increase in the serum levels of CA19-9, CA125 (in males), CYFRA 21-1, NSE and SCC-Ag in patients with CKD affects the specificity of these markers in the diagnosis of cancer. Hemodialysis does not affect the serum levels of CA19-9, CA125, AFP, CA15.3, CA72.4, CYFRA 21-1, NSE and SCC-Ag.
