title: [Renal enzyme excretion in tumors and tumor therapy].
abstract: None of the hitherto investigated enzymes of the urine can be used as marker for the proof of tumours. Hopeful starts in this respect are to be seen in an increased beta-glucuronidase excretion and in a decreased gamma-glutamyl transpeptidase excretion as well as in an increased LDH5/LDH1 ratio. The lysozyme excretion with the urine gives important references to the differential diagnosis, the assessment of the prognosis and therapy of acute leucoses. An importance obtained enzyme determinations in the urine for the clarification of pathobiochemical processes of the alteration of the kidney by neoplasms, tumour-lysis-syndromes, cytostatics, tumour radiation and operations of tumours. Courses of enzyme excretion during tumour therapy which as a rule show a rhythmic hyperenzymuria allow conclusion to the moment of the flow the catabolic products of the tumour at the kidney and to the different reaction of the tubular epithelium to these substances.
