Adjuvant chemotherapy in breast cancer

One single course of i.v. cyclophosphamide (30 mg/kg) was given over a 6-day period to 559 mastectomized patients. During a follow-up period of up to 15 years, 241 recurrence and 234 deaths are registered in this group, and 294 recurrences and 283 deaths in the randomized control group of 577 patients. Analysis of the life-table curves shows an increased cure rate of about 10%.
