title: Inhibition of cisplatin toxicity without decreasing antitumor efficacy. Use of a dithiocarbamate.
abstract: OBJECTIVE
  To demonstrate whether a dithiocarbamate derivative, N-methyl-D-glucaminedithiocarbamate, could prevent anorexia and weight loss and enhance survival without decreasing the antitumor efficacy of high-dose cisplatin therapy.
  
  
  METHODS
  One hundred forty-two mice were randomized into groups receiving cisplatin, 5 mg/kg per day, 7.5 mg/kg per day, or 10 mg/kg per day for three days with or without N-methyl-D-glucaminedithiocarbamate, 1000 mg/kg per day. Weight loss and morbidity were examined between groups. Antitumor efficacy of cisplatin combined with N-methyl-D-glucaminedithiocarbamate was examined using a subcutaneous melanoma model.
  
  
  METHODS
  Institutional laboratory.
  
  
  METHODS
  N-methyl-D-glucaminedithiocarbamate intervention would decrease morbidity, weight loss, and increase survival without decreasing the antitumor efficacy of cisplatin.
  
  
  RESULTS
  Weight loss and morbidity were significantly reduced when N-methyl-D-glucaminedithiocarbamate was coadministered with cisplatin (P < .05) at all doses of cisplatin. The antitumor efficacy of high-dose cisplatin therapy (7.5 mg/kg per day and 10 mg/kg per day) was not significantly decreased (P > .05) at all doses of cisplatin.
  
  
  CONCLUSIONS
  As N-methyl-D-glucaminedithiocarbamate seems to limit morbidity and mortality of high-dose cisplatin administration without decreasing its antitumor efficacy, this drug deserves further investigation in the treatment of cancer.
