Radioimmunodetection of human colorectal cancers by an anti-tumour monoclonal antibody. 1982

P A Farrands, and A C Perkins, and M V Pimm, and M J Embleton, and J D Hardy, and R W Baldwin, and J D Hardcastle

In 10 out of 11 patients with colorectal cancer radiolabelled antitumour monoclonal antibody (791T/36) was localised to the tumour. The mean tumour to non-tumour uptake ratio of antibody demonstrated by imaging with a gamma camera was 4.4/1 after subtraction of background radioactivity. The antibody did not localise in one patient who had received radiotherapy to his tumour two weeks previously. In 5 patients with primary neoplasms localisation of the antibody was confirmed by further imaging of the resected specimens and in-vitro radioactivity counting of the tumour and comparison with the activity in adjacent normal colon.

UI MeSH Term Description Entries
D007457 Iodine Radioisotopes Unstable isotopes of iodine that decay or disintegrate emitting radiation. I atoms with atomic weights 117-139, except I 127, are radioactive iodine isotopes. Radioisotopes, Iodine

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D011856 Radiographic Image Enhancement Improvement in the quality of an x-ray image by use of an intensifying screen, tube, or filter and by optimum exposure techniques. Digital processing methods are often employed. Digital Radiography,Image Enhancement, Radiographic,Radiography, Digital,Enhancement, Radiographic Image,Enhancements, Radiographic Image,Image Enhancements, Radiographic,Radiographic Image Enhancements
D011877 Radionuclide Imaging The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.
