ACCELERATED CHEMOTHERAPY FOR POOR-PROGNOSIS GERM-CELL TUMORS

A pilot study has been completed of an innovative dose intensive chemotherapy schedule for poor prognosis patients with metastatic germ cell tumours referred to the Royal Marsden Hospital between August 1989 and January 1992. The rationale underlying the regimen was the use of an extremely short intercycle interval in order to counteract the potential of these tumours for rapid proliferation. The drug combination in the first phase incorporated a combination of cisplatin and carboplatin, infusional bleomycin and vincristine and this was followed by three cycles of bleomycin, etoposide and cisplatin (C-BOP/BEP). 21 patients with adverse presentations were treated with C-BOP/BEP. The median follow-up of surviving patients is 36 months (range 18-52 months). 1 patient died of disease, 1 died of a treatment complication while in remission and 1 further patient relapsed, and is in remission after radiotherapy and surgery. The 2-year overall survival rate was 90% [95% confidence interval (CI) = 77-100%]. We conclude that this approach may represent an improvement over standard chemotherapy and should be assessed in a multicentre setting.
