Blood group antigens and carcinoembryonic antigen (CEA) were sought in the tissues of 37 bladder tumor cases using enzyme antibody method. A correlation (p < 0.01) was found between the extinction of ABO (H) and progressive malignant states of the tumor or invasion stage. Significant correlation (p < 0.05) was observed between the presence of CEA and the invasion stage. The state of the T antigen, however, did not reflect the malignancy grade or invasion stage. The states of ABO (H) and CEA significantly reflected (p < 0.05) the prognosis, as did the malignancy grade and invasion stage, while the state of the T antigen did not correlate with the prognosis. Although there was a correlation (p < 0.01) between the extinction of ABO (H) blood group antigens and the presence of CEA, the state of T antigen did not significantly correlate with ABO (H) antigen or CEA. From what has been mentioned, the search for intratissue ABO (H) antigens and CEA is important and will provide a useful auxiliary means in diagnosing biopsy specimens.
