The Use of Pentoxifylline and Vitamin E in the Treatment of Late Radiation Related Injuries
August 12, 2010 updated by: University Health Network, Toronto
A Phase II Study of the Use of Pentoxifylline and Vitamin E in the Treatment of Late Radiation Related Injuries
Patients with radiation induced injuries experience significant pain and negative effects on quality of life.
Currently, no standard therapy for these patients exists, with some patients treated symptomatically, and others treated with hyperbaric oxygen or pentoxifylline/Vitamin E. This study will examine prospectively the safety and efficacy of using a regimen of pentoxifylline and vitamin E in patients with late radiation induced injuries.
