title: The study on cell surface antigens in epithelial tumor of the upper urinary tract: ABH-isoantigen and Thomsen-Friedenreich antigen.
abstract: ABH-isoantigen (ABH-Ag) and Thomsen-Friedenreich antigen (T-Ag) were investigated by the Avidin-Biotin-Peroxidase Complex (ABC) method on 47 patients with epithelial tumor of the upper urinary tract (all patients underwent nephroureterectomy including the cuff of the bladder; 30 patients were diagnosed as transitional cell carcinoma of renal pelvis and 17 ureteral organs). The correlations between ABC expression for ABH-Ag and T-Ag with histological grade, stage and prognosis (5 year survival rate) were studied. A correlation was observed between grade (p less than 0.05) and deletion of the antigenicity of ABH-Ag, but no correlation was evident with stage and prognosis. A high correlation was evident, however, between grade (p less than 0.01), stage (p less than 0.01) and prognosis (p less than 0.01) and deletion of the antigenicity of T-Ag. The analysis of ABC expression for ABH-Ag and T-Ag may therefore be valuable for predicting the malignant potential in transitional cell carcinoma of the upper urinary tract. T-Ag determination in particular may provide a useful prognostic probe should it find clinical application.
