[Immunofluorescence study of the distribution of ABH cell surface antigens in bladder tumours (author's transl)].

ABH antigens are normally present at the surface of the healthy urothelium. In many cases of bladder tumours, the urothelium loses its antigens. While this loss would not seem to be associated with the grade or stage of the tumour, the persistence of the ABH antigens would seem to provide a more favourable prognosis.
