  • Title: Excretion of polyamines by children with leukemia during chemotherapy.
    Author: Mach M, Schneider U, Kersten W.
    Journal: Recent Results Cancer Res; 1983; 84():413-20. PubMed ID: 6573734.
    Abstract:
    Evidence is presented showing a relation between polyamine concentration and the methylation of tRNA in vitro and in vivo. Polyamine excretion in urine of children with ALL and AML is slightly elevated before the commencement of chemotherapy. Immediately thereafter, excretion of acetylputrescine increases drastically over a period of at least 30-60 days. The elevation seems to be caused by different factors, e.g., destruction of tumor cells, induction of ornithindecarboxylase, and cell recovery after termination of chemotherapy. Acetylspermidine excretion also increases 3-4 days after the beginning of chemotherapy. A positive correlation exists between leukocyte counts and excretion of acetylspermidine. The ratio of acetylspermidine excretion at days 3-4 of the therapy to that before commencement of chemotherapy could be an indicator of response to the therapy.
