Multiple marker validity of urinary hexosaminidase and polyamines in haematopoietic malignancy

Proliferation end products are of considerable value as tumour markers. Hexosaminidase and polyamines were significantly elevated in urine of patients with leukemia and lymphoma (p less than 0.001). Interfering low molecular weight compounds were eliminated by a microcolumn centrifuge method. Urinary polyamines were estimated by high voltage electrophoresis technique. Marked increase in these markers in untreated patients and subsequent decrease on effective chemotherapy support the use of these two tumour markers to monitor therapeutic response.
