title: [Diagnostic value of 4 biological markers: lactate dehydrogenase, phosphoglucoisomerase, carcinoembryonic antigen and gammaglutamyl transpeptidase, systematically determined in patients in a hematology-oncology department].
abstract: This article is concerned with a prospective study about the systematical, simultaneous and comparative assay of four biological markers (carcino-embryonic antigen, lactate dehydrogenase, gammaglutamyl transferase and phosphohexose isomerase). This study was conducted in a department of Hematology and oncology on 258 patients. The dosage of each marker separately does not appear to be of diagnostical interest because of a lack of sensibility and specificity. But when there is a positive statistical correlation between several makers, their simultaneous dosage may allow the diagnostic of cancer and sometimes the determination of its origin.
