Tissue blood-group antigens and prognosis in low stage transitional cell carcinoma of the bladder.
The loss of A, B or H blood-group antigens from the surface of neoplastic epithelial cells has been correlated with aggressive tumor behavior. We examined this phenomenon in low stage transitional cell carcinoma of the bladder. In an analysis of biopsy material from 37 patients the absence of these antigens on the original or recurrent tumors correlated with the subsequent development of invasive disease (stage B or greater), while the presence of antigens correlated with failure to develop invasive disease. Analysis of transitional cell surface antigens may help improve the therapy of bladder cancer.
