Bleomycin: its utilization in the treatment of head and neck cancer.

Originally isolated as an antibiotic, bleomycin is a complex mixture of glycopeptides currently utilized against a variety of malignancies, among them epidermoid, cancer of the head and neck. Because of unique independent pharmacological properties, bleomycin may be effectively used at several points in the natural history of tumors. Use of bleomycin as a single agent, as an adjunct to surgery and irradiation and as a palliative drug in head and neck cancer, is now advocated in scattered reports. The rationale for the utilization of bleomycin at the University of California, San Diego and San Diego Veterans Administration Hospitals is discussed. In addition, examples from the authors' personal series of both response and adverse effects, suggestions for appropriate clinical monitoring to detect early toxicity, and tennets for management of side effects are included in the presentation.
