Abstract

Currently, the cell surface antigen A,B,O(H) is thought to be an important indicator of malignant potential in bladder carcinoma. Herein, we performed SRCA test in 54 bladder carcinoma for detection of such an isoantigen, comparing the SRCA result to its tumor grade and stage. Also, various significances including the clinical application of SRCA test for the management of the bladder carcinoma were discussed. The results were as follows: 1. Of 54 patients, 34 patients were low stage(0-A) and low grade(1-2). 2. There is a significant correlation between tumor grade and SRCA test: Of 38 patients with low grade. 19 patients were SRCA positive, but of 16 patients with high grade. all were SRCA negative. 3. There is a significant correlation between tumor stage and SRCA test: Of 36 patients with low stage, 18 patients were SRCA positive, but of 18 patients with high stage(above B1), only one patient was SRCA positive. 4. There is a high possibility of false-negative results in detecting O(H) isoantigen: Of 36 patients with low stage, 6 patients were blood group 0 who were all SRCA negative. but 30 patients with other blood groups showed variable SRCA results. 5. There is a considerable correlation between tumor recurrence and SRCA result: Of 20 patients who were followed more than one year after initial TUR, 8 patients were SRCA positive, of these 4 patients were recurred, but 9 patients of 12 patients with SRCA negative were recurred.
