To evaluate the immune system of patients with bladder transitional cell carcinoma (TCC) by using peripheral blood lymphocyte subsets and to further compare the relationship between these subsets with respect to tumor stage and grade (superficial versus invasive and low versus high grade).


Thirty patients with superficial TCC of the bladder, 30 patients with invasive TCC of the bladder, and 30 age- and sex-matched control subjects without any malignancy or immunologic abnormality were included in this study. The peripheral blood lymphocyte subset analysis was performed in all patients before any treatment was performed.


All lymphocyte subset values of patients with invasive bladder cancer, except B cell value, were significantly lower (P < 0.01) than the values of the control group. There were no significant differences between the lymphocyte subset values of patients with superficial bladder cancer and those of control subjects. The comparison of the lymphocyte subset values of the patients with superficial versus invasive bladder carcinoma revealed that in patients with invasive bladder carcinoma, the numbers of T and natural killer (NK) cells were significantly lower (P < 0.05) than those of patients with superficial bladder carcinoma. Patients with high-grade tumors had significantly fewer (P < 0.05) T and NK cells than patients with low-grade tumors.


Our results indicate that analysis of mean NK and T cell values and the mean ratio of CD4+/CD8+ cells in peripheral blood might be a useful adjunct for the clinical evaluation of patients with bladder cancer.
