Acquired Renal Cystic Disease and Tumor Markers in Chronic Hemodialysis Patients

Abstract

Acquired renal cystic disease (ARCD) is a well documented complication of end-stage renal disease, and it has been related to the duration of dialysis therapy. The association of this condition with renal cell adenoma or carcinoma has already been established. There have also been studies on the concentration of some tumor markers in hemodialysis (HD) patients, clinically free from neoplastic disease, where it was concluded that some tumor markers could be elevated, despite the absence of malignant disease, suggesting their altered metabolism i.e. clearance by the hemodialysis membrane. We compared the pre-dialysis serum concentration of several tumor markers in three groups of chronic HD patients, all of whom had been on maintenance HD treatment for more than 5 years. Group 1 consisted of 16 patients without ARCD with a mean HD treatment duration of 97.06 +/- 28.25 months. Group 2 consisted of 32 patients with a mean HD treatment of 105.62 +/- 24.4 months, who had ARCD with less than 10 renal cysts detected by ultrasonography. Group 3 consisted of 14 patients with a mean HD duration of 109.92 +/- 37.72 months, with ARCD and more than 10 renal cysts. Concentration of the following tumor markers was determined by EIA or ELISA methods: carcinoembryonic antigen (CEA), mucin-like carcinoma-associated antigen (MCA), neuron-specific enolase (NSE), carbohydrate antigen 19-9 (CA 19-9), prostatic specific antigen (PSA), carbohydrate antigen 125 (CA 125), alpha fetoprotein (AFP), cytokeratin 19-fragments 21-1 (CYFRA 21-1). The concentration of all the tumor markers was comparable in all three patient groups, with no statistically significant difference between groups. The mean concentrations of MCA, PSA, CA 125 and AFP were within the normal range. CEA and CYFRA 21-1 had mean values in the upper limit of their normal values, while NSE and CA 19-9 were increased by more than twofold in all three patient groups. We concluded that (i) tumor markers should be used with caution when diagnosing neoplastic diseases in chronic HD patients, because of their altered metabolism, and (ii) that in the follow up of ARCD with possible neoplastic alteration, imaging techniques remain dominant diagnostic tools.

Disappearance Curves for Tumor Markers after Resection of Intrathoracic Malignancies

“…When patients with reduced renal function (CCr<55 mL/min) were excluded from our material, the average CEA half-life was 0.7 ± 0.2 (0.4-1.0) days. The same result was reported for CA 19-9, SCC, TPA and CYFRA (16)(17)(18). However, we did not observe this type of correlation with any other tumor marker except CEA.…”

Reviews: Altered Laboratory Findings Associated with End‐Stage Renal Disease

“…The commonly observed increased serum levels of CEA, NSE, SCC, and fPSA suggest the possibility of renal metabolism and clearance of these markers (89,90). Newer tumor markers (such as CA 19.9 and CA 50) appear to maintain their clinical value in chronic renal failure (91,92).…”

Serum Levels of CA15-3, AFP, CA19-9 and CEA Tumor Markers in Cancer Care and Treatment of Patients with Impaired Renal Function on Hemodialysis

“…The serum tumor markers are proteins or glycoprotein which depending on their type are secreted by tumoral and normal cells (Tzitzikos et al, 2010). Application of these secreted substances can be used as a assessment of disease recurrence (Polenakovic et al, 1997;Danişman et al, 2000;Richard and Pincus, 2007). Tumor marker concentrations in healthy individuals is low or zero, and its increasing suggest the incidence of related Tumor (Danişman et al, 2000;Richard and Pincus 2007;Xiaofang et al, 2007;Tzitzikos et al, 2010).…”
