Abstract:
Objective To investigate the optimum doses of combined chemotherapy with cyclophosphamide (CTX) and cisplatin (DDP).Methods 120 cases of ovarian cancer and malignant lymphoma were divided randomly into 6 groups.Drugs were administered to each group:CTX 500 mg/m2 + DDP 40 mg/m2,CTX 500 mg/m2 + DDP 50 mg/m2,CTX 500 mg/m2 + DDP 60 mg/m2,CTX 600 mg/m2 + DDP 40 mg/m2,CTX 600 mg/m2 + DDP 50 mg/m2,CTX 600 mg/m2 + DDP 60 mg/m2.Drugs were administered intravenously once a week for 2 consecutive weeks.Changes in the efficacy and adverse reaction were compared among the groups.Results There was no significant efficacy difference among the groups (P ＞ 0.05).Leukocyte inhibition rate (72.6 ％ and 79.3 ％,respectively) and damage to lymphocyte were maximal in the high-dose chemotherapy groups (CTX 500 mg/m2 + DDP 60 mg/m2,CTX 600 mg/m2 + DDP 60 mg/m2),and the levels of creatinine,blood urea nitrogen,alanine aminotransferase (ALT) in serum and aspartate aminotransferase (AST) were reduced significantly,whereas the hemogram was within normal range in the lowdose chemotherapy group (CTX500 mg/m2 + DDP 40 mg/m2),and the frequencies of damage to renal function and hepatic function were low.Conclusion The optimum dose of combined chemotherapy with cyclophosphamide and cisplatin was CTX 500 mg/m2 and DDP 40 mg/m2.
