Acute phase reactant proteins in the clinical management of carcinoma of the bladder.

The levels of a number of acute phase reactant proteins have been measured in 250 patients with carcinoma of the bladder in all stages. Three of them, acid glycoprotein, antichymotrypsin, and C-reactive protein, frequently gave abnormal results in advanced disease. The levels of these 3 proteins in patients who were clinically tumour-free were not distinguishable from those from an age-matched control group. The levels in patients with T1 and T2 bladder tumours were sometimes elevated. In advanced disease, figures were commonly above the normal range.
