Chromosomal abnormalities are commonly associated with cancer, and their importance in the pathogenesis of the disease has been well recognized. Also recognized in recent years is the possibility that, together with chromosomal abnormalities, DNA ploidy of breast cancer aspirate cells, measured by image cytometric techniques, may correlate with prognosis of(More)
Present evidence suggests that the cell surface has an important role in metastasis. To examine this idea further, the surface properties of single cells isolated from the primary growths of a liver-metastasizing (ML) and a non-metastasizing (NML) lymphosarcoma were compared for adhesion to cell monolayers, cytopherometry, isoelectric focusing, adhesion to(More)
The high molecular weight form of the plasminogen activator urokinase (54 kD) binds to specific receptor sites on the cell membrane of breast carcinomas by its inactive "A" chain. The binding is of high affinity (range of dissociation constants: 5.6 X 10(-11) to 4 X 10(-10) mol l-1 and there were between 20 to 250 fmol of binding sites per milligram of(More)
—The presence of metastasis in the regional lymph nodes is the most important factor in predicting prognosis in breast cancer. Many biomarkers have been identified that appear to relate to the aggressive behaviour of cancer. However, the nonlinear relation of these markers to nodal status and also the existence of complex interaction between markers has(More)
This study was aimed at determining whether tumour DNA content measured by cell image analysis could provide additional prognostic information when compared to that provided by flow cytometry. Sections cut from paraffin blocks of tumours from 101 patients with node negative breast cancer were analysed by both methods and the results related to other(More)
THE IMPORTANCE of tumour markers for the detection of malignancies, and for determining the extent and the clinical course of the disease, has prompted much investigation into the establishment of possible biochemical markers for breast cancer. Although tumour-associated products such as the carcinoembryonic anti-gen (Wang et al., 1975; Tormey et al.,(More)
