[Disorder of serum electrolytes following CAP therapy].

Combination chemotherapy with Cyclophosphamide, Adriamycin and Cisplatin (CAP) is one of the most effective chemotherapies for ovarian cancer. Severe vomiting induced by this treatment may cause a disorder of the serum electrolytes. Severe hyponatremia was observed in one patient who complained of convulsions and unconsciousness. Accordingly we studied the disorder of serum electrolytes in 158 courses of CAP treatment (44 patients) during the five years from 1984 to 1988. The serum electrolytes were influenced by the amount of vomiting in this study. Consequently frequent examination of serum electrolytes is necessary during this treatment.
