OBJECTIVES: This study was planned to evaluate the feasibility of the assay of leukocyte arylsulfatase-A (AS-A) activity, and some urinary cytokine levels (tumor necrosis factor-alpha [TNF-alpha] and interleukin-8 [IL-8]), as noninvasive diagnostic tools in different stages of bladder cancer patients. DESIGN AND METHODS: Blood and urine samples of 79 subjects were analyzed, including 28 healthy volunteers, 27 patients with superficial bladder cancer (SBC), and 24 patients with muscle invasive bladder cancer (MIBC). RESULTS: In SBC patients, the mean leukocyte AS-A activity was slightly higher (11.4%) than healthy subjects without reaching statistical significance. On the other hand, the enzyme activity in MIBC patients was significantly higher than those of controls (38.9%) and SBC patients (18.3%). Urinary TNF-alpha levels in both cancer groups were not significantly different from the control group. Urinary IL-8 levels of MIBC patients were significantly increased when compared with the levels of SBC patients and healthy subjects (P < 0.001). CONCLUSIONS: Based on our results, it may be concluded that measurement of leukocyte AS-A activity is not a sufficiently reliable noninvasive diagnostic test in distinguishing early stage bladder cancer from healthy subjects as well as detecting disease progression. Whereas measurement of urinary IL-8 may be valuable as a noninvasive diagnostic and prognostic test especially in patients with advanced bladder cancer. It also appears that complementary biochemical information may be obtained about the prognosis of the disease by monitoring urinary IL-8 profile. However, further confirmatory clinical trials about the prognostic value of the measurement of urinary IL-8 are needed.
