Summary: This programme is presented as a dialogue, dealing with the specific antigenicities of tumour cell populations. The antigens are of three broad types, those associated with viral tumours, those in chemically-induced tumours, and embryonic antigens. The methods of detection of the antigens are discussed, with emphasis on the different results obtained with human tumours and the lack of suitable in vitro test systems other than with experimental animals. The failure of immune responses to dislodge tumours is discussed, as well as various means by which an anti-tumour response might be augmented in favour of the patient. 7 segments.
