Cyclic high dose CAP therapy by short-stay admission for ovarian malignancies--to increase total dose of CDDP and to improve quality of life of patients

Since 1986, attempts have been made to improve the anti-cancer effect of Cisplatin (CDDP) in malignant ovarian tumor patients and their quality of life (QOL), by increasing single and total dose of CDDP and by short-stay cyclic treatment at our institution. In this study, the side effects of CDDP at high and low doses were compared and the effect on the QOL was analysed. Twenty ovarian malignant tumor patients who underwent adjuvant chemotherapy (CDDP 70 mg/m2, Adriamycin (ADR) 20 mg/m2, Cyclophosphamide (CPM) 200 mg/m2 given every 4 weeks for a total of 5 times and every 8-12 weeks thereafter for 5 times) after initial surgery were compared with non randomized control patients who received the old regimen of of our institution (CDDP 35 mg/m2, ADR 20 mg/m2, CRP 200 mg/m2, 5-FU 150 mg/m2 for 5 days given every 4 weeks for a total of 5 times without discharge from hospital). There was no significant difference between the groups in the white blood cell (WBC) count and creatinine clearance (Ccr) throughout the treatment, although a slight drop was observed after the second course in both groups. The QOL was examined by interviewing the patients on their physical and mental condition. Although the total amount of CDDP was increased from 175 mg/m2 to as much as 700 mg/m2, no severe nephrotoxicity or myelosuppression was seen and patients felt better and preserved a good QOL during a short hospital stay. These results clearly indicate the efficacy of our new regimen.
