title: Lymphocyte fluorescent profiles (LFP): a possible screening technique in neoplasia.
abstract: A technique involving fluorescent protein staining and microfluorometry has been developed for measuring the lymphocyte fluorescent profile (LFP) of peripheral blood lymphocytes. In contrast to normal humans who display a regular bell-shaped curve, the profile from patients with cancer is irregular, showing a bimodal distribution of fluorescence, with a significant population of cells fluorescing at a higher relative intensity. It is suggested that this elevation in protein concentration is due to an immune response to the presence of a neoplasm, and thus this technique may prove to be a useful indicator of malignancy.
