Vinblastine, bleomycin and cis-diamminedichloroplatinum in the treatment of advanced testicular carcinoma. Possible importance of longer induction and shorter maintenance schedules

Abstract

Twenty-eight patients with stage III or recurrent stage I or II testicular cancer were treated with four to six cycles of vinblastine, bleomycin and cis-diamminedichloroplatinum, and then with vinblastine maintenance for one year. With a median follow-up of more than 20.5 months for all patients, complete remission has been achieved with chemotherapy and operation in 23 (82 per cent). One of these 23 patients has had a relapse, and only three are still receiving maintenance therapy. The toxicity incurred by the extra cycles of chemotherapy in patients with extensive disease was no greater than that experienced by patients receiving smaller doses of drugs. These results confirm the high response rate reported for this combination of drugs and strongly suggest that some relapses after complete remission can be prevented by longer remission induction schedules. The value of maintenance therapy is questionable and needs further study.
