Cyclophosphamide and VP 16-213 with autologous bone marrow transplantation. A dose escalation study.

In 13 patients with therapy-resistant solid tumors the feasibility of high-dose cyclophosphamide (7 g/m2) in combination with increasing doses of VP 16-213 with autologous bone marrow transplantation was studied. Dose-limiting extramedullary toxicity appeared to be mucositis and occurred after 2.5 g/m2. Two toxic deaths were observed in patients older than 55 yr. Responses were seen in eight out of nine evaluable patients. Two patients with ovarian cancer still have no signs of disease progression after 12+ months. High-dose cyclophosphamide (7 g/m2) can be combined with VP 16-213 1.5 g/m2 without important extramedullary toxicity. Age is probably a limiting factor for this kind of therapy.

Current status of systemic chemotherapy in the treatment of advanced ovarian cancer with emphasis on CHAP-5.

In patients with advanced ovarian cancer, initial treatment with combination chemotherapy, including cyclophosphamide and cis-platinum diamminedichloride (cis-platinum), produces response and progression-free survival results which are superior to those achieved with alkylating single-agent chemotherapy. Unfortunately most schedules have not resulted in a statistically significant improvement of overall survival. So far one of the most effective combination regimens is the four-drug regimen CHAP-5 that consists of cyclophosphamide, hexamethylmelamine, adriamycin, and cis-platinum. This regimen is the first schedule to result in significant improved survival times compared with a second combination schedule, i.e. Hexa-CAF, which is at least as good as alkylating therapy alone. The CHAP-5 regimen was rather toxic but it was manageable and easy to apply in daily practice. Further improvement of the treatment results in advanced ovarian carcinoma will be difficult because no effective new drugs are available. In future clinical research it must be tried to decrease the toxicity and morbidity of the current schedules without reducing efficacy and survival.

Treatment of malignant germ cell tumors of the ovary with cisplatin, vinblastine, and bleomycin (PVB).

Seven patients with germ cell tumors of the ovary were treated with four cycles of cisplatin, vinblastine, and bleomycin. Six patients were without evidence of disease 17+ to 37+ months after completion of the remission-induction chemotherapy, and one patient relapsed after 9 months. Substantial toxicity of the cisplatin, vinblastine, and bleomycin regimen was noted. Despite the high response rate suggested in this small series, the optimal chemotherapeutic treatment for this disease has yet to be determined.

High-dose etoposide for refractory malignancies: a phase I study.

Etoposide is active against a number of solid tumors when used in a standard dose. The toxicity at a standard dose level is mild myelosuppression without extramedullary toxicity. Recent studies in man support the dose-response relationship of etoposide. In a group of 22 patients with progressive disseminated malignancies, the dose of etoposide was escalated to define dose-limiting extramedullary toxicity, which was oropharyngeal mucositis at a dose level of 3.5 g/m2. Bone marrow toxicity was completely reversible. No cumulative toxicity was seen. Partial responses were seen in nine patients. In two of three patients with CNS metastases, improvement was seen. Etoposide is a suitable drug for high-dose chemotherapy.
