the theoretical possibility that the heterogeneous clones that comprise prostatic cancer might be killed or controlled by selective targeting of cytotoxic agents ( actual or potential ) to malignant cells is discussed in terms of two types of delivery vehicles to provide for cell selectivity : ( 1 ) monoclonal antibodies against specific cell surface markers on cancer cells and ( 2 ) steroid ligands for receptors present in clones of malignant cells .
