[Urinary excretion of cytokines in bladder carcinoma].
OBJECTIVE
Analysis of the urinary excretion of cytokines in vesical carcinoma.


METHODS
The study includes the results obtained in the quantification of several interleukins (IL-1, IL-2, IL-4, IL-6, INF-gamma and TNF-alpha) in urine samples corresponding to 60 patients with transitional cell carcinoma (TCC) with vesical location (40 surface and 20 infiltrant). Concurrently, 40 healthy donors and 20 patients with urinary tract infections were studied. Determination of the various cytokines was done with ELISA enzyme-linked immunoassays.


RESULTS
The results obtained in the study show that: a) urinary concentrations of IL-1, IL-2, IL-6, TNF- and INF- in surface TCC, are similar to those found in healthy subjects; b) levels of the mentioned cytokines are significantly higher in patients with urinary infections; c) in patients with infiltrant TCC, IL-6 urinary concentration is significantly higher than in those with S-TCC; d) urinary IL-4 levels show no difference between the various groups under study.


CONCLUSIONS
From all the above it is concluded that there is a large diversity in the excretion of urinary cytokines from the vesical urothelium based on antigenic stimulation (bacterial or tumoral) to which it has been exposed and the tumoral stage, and that baseline determination of IL-6 urine level in patients with vesical TCC could have some prognostic influence.
