Abstract: | Labelled macrophages accumulate in Walker carcinosarcoma-256 after in vivo and in vitro stimulation with a lectin and are theretically suitable for scintigraphic tumour detection. At present, routine application of the technique in man is precluded by: (1) the use of PHA, and (2) a labelling method for macrophages with considerable limitations to its application and which results in significant uptake of activity in liver and spleen. However, the purpose of the study was primarily to demonstrate the principle of a possible alternative to the use of labelled monoclonal antibodies for the scintigraphic detection of tumours. |
