And for those who think they need WBR there is hyperbaric oxygen therapy (above). It's good to see a resurgence of research into this valuable technology. Until the new millenium, the only treatment for patients for radiation-induced necrosis was pentoxifyline or heparin therapy, and it was almost always unsuccessful. Both Duke University for Hyperbaric Oxygen Therapy and the University of Cincinnati previously had successful clinical trials on this science. The most common condition treated at some hyperbaric oxygen therapy centers is tissue injury caused by WBR.
Wound healing requires oxygen delivery to the injured tissues. Radiation damaged tissue has lost blood supply and is oxygen deprived. Chronic radiation complications result from scarring and narrowing of the blood vessels within the area which has received the treatment. Hyperbaric oxygen therapy provides a better healing environment and leads to the growth of new blood vessels in a process called re-vascularization. It also fights infection by direct bacteriocidal effects. Using hyperbaric treatment protocols, most patients with chronic radiation injuries can be healed.
Emmay points out something important. One of the most popular combinations for brain tumors is CPT-11 (Camptosar) and Avastin. As with most targeted therapy drugs, Avastin does not necessarily benefit every patient and it is expensive. Until now, there were not tests that existed to show reliably who would benefit from anti-angiogenic agents.
