Abstract:
Objective To study the significance of rDNA transcription activity of peripheral blood T lymphocyte in patients with urinary tract tumors. Methods rDNA transcription activity of peripheral T lymphocyte was detected by a cell image analysis of Ag-NOR in 21 patients who were pathologically diagnosed with kidney cancer (including 6 cases of T_1N_0M_0,9 of T_2N_0M_0,4 of T_3N_0M_0 and 2 of T_4N_2M_1) and in 42 patients with bladder tumor (including 14 cases of TaN_0M_0,11 of T_1N_0M_0,1 of T_1N_0M_1,8 of T_2N_0M_0,4 of T_3N_0M_0 and 4 of T_4N_0M_0).Twenty-eight normal volunteers served as controls and 23 patients with uremia as positive controls.The peripheral blood was taken for detection of Ag-NORs in controls and in tumor patients before and after operation.The differences were compared among these groups. Results rDNA transcription activity of T cells was (8.55?1.11)%,(6.29?0.97)%,(5.44?0.68)% and (5.42? 0.68)% in controls and patients with uremia,renal and bladder tumors,respectively,showing a statistically significant difference among the normal uremia and tumor patients (P0.05).The parameters,such as TNM stages of renal and bladder tumor,the cell grades according to WHO criteria,tumor volume of the kidney,and invasion depth and recurrence frequencies of bladder tumors,had no significant correlation with rDNA transcription activity of T cells. Conclusions rDNA transcription activity of T cells may be used for monitoring the immune function in patients with kidney and bladder tumors,especially for primary screening of urinary tract tumors.
