The investigation was concerned with clinical application of cardioxane (dexrazoxan, ICRF-187) which is intended to counteract the cardiotoxic effect of anthracycline drugs. It was tested in 24 courses of combination chemotherapy (CAP) in 48 cases of extended ovarian tumor. The "threshold" total dose of doxorubin (500 mg/m2) which caused persistent cardiomyopathy in such patients as well as cases of relapse was practically never reached due to the absence of therapeutic effect. The total dose of doxorubicin of 120 mg/m2 raised the likelihood of acute cardiac intoxication. With prophylactic administration of cardioxane, clinical signs of acute cardiointoxication were slight; irreversible intoxication was recorded in 0.8%. The drug improved tolerance; it neither increased the overall toxicity of combination chemotherapy nor affected the results.
