[Detection of circulating immune complexes by polyethyleneglycol precipitations complement consumption test in urological malignant diseases].
Circulating immune complexes (CIC) were detected and quantitated in 49 patients with urological malignant diseases (9 cases of renal cell cancer, 3 cases of renal pelvic and ureter cancer, 21 cases of bladder cancer and 16 cases of prostatic cancer), 9 patients with urological benign diseases and in normal subjects by the polyethylene-glycol precipitation complement consumption test (PEG-CC test). The average CIC level was 2.7 +/- 3.0% in 18 normal subjects and the normal range was less than 10% of the CIC level. CIC level of patients with renal cell cancer was 14.3 +/- 20.1%, being elevated in 3 of the 9 patients, that of patients with renal pelvic and ureter cancer was 4.7 +/- 4.6%, being within the normal range in 3 cases, that of patients with bladder cancer was 4.7 +/- 4.4%, being elevated in 1 of 21 patients, and that of patients with prostatic cancer was 8.9 +/- 15.4%, being elevated in 3 of 16 patients. In urological malignant diseases such as renal cell cancer and prostatic cancer the CIC values were relatively high.
