Prolonged administration of bleomycin without clinical toxicity. Therapy with 2,700 units over four years.

A 26-year-old white man with stage 4-B Hodgkin's disease resistant to conventional chemotherapy obtained complete remission with administration of bleomycin. Maintenance of this remission required continued therapy with bleomycin. The patient received a total of 2,700 units of bleomycin over a 51-month period without signs or symptoms of pulmonary toxicity. Serial studies of pulmonary function have shown a stable forced vital capacity and minimally decreased total lung volume and pulmonary diffusing capacity. This case demonstrates the ability of a patient to tolerate massive cumulative doses ob bleomycin over a protracted period without severe loss of pulmonary function.
