[Bladder tumors: prognostic value of surface antigens and carcinoembryonic antigens. A retrospective study]

Seven patients presenting with recurrent diffuse, non-infiltrating tumors of the bladder were treated for several years by repeated endo-urethral resection, because radical exeresis was not possible. Each operative specimen was subjected to examination of the ABH blood-group antigens, pneumo-14 precursor, and carcino-embryonic antigens. The authors emphasize the prognostic interest of such studies.
