The effects of platinum chemotherapy on essential trace elements.
The effects of cisplatin chemotherapy on the metabolism of essential trace elements were investigated in 12 patients before and after treatment with cisplatin. In serum, the mean post-treatment concentrations of Cu 913.91 mumol 1-1), Zn (9.57 mumol 1-1) and Mg (0.54 mumol 1-1) were significantly reduced compared with the pre-treatment levels 919.35, 11.86 and 0.67) while Se, caeruloplasmin and C-reactive protein concentrations were unaltered. Urinary excretion of Cu, Mg and Zn were enhanced. The urinary N-acetyl-beta-D-glucosaminidase activity (a marker of proximal renal tubular dysfunction) was also increased and suggests that the mechanism for decrease of certain trace elements in serum during treatment could be increased urinary excretion caused by impaired cellular metabolism. It is not clear whether the loss of trace elements via the urine has any implication for the clinical status of cancer patients treated with cisplatin.
