[The possibilities of protection against local radiation injuries in ORL-oncologic patients]

Quercetin granules and gel were used to provide local protection in 64 ENT-cancer patients given radiotherapy. The highest effect was obtained as a result of a combined (per os and topical) application of quercetin throughout the entire radiotherapy course. The use of quercetin granules to treat acute radiation-induced epithelitis was effective and allowed radiotherapy to be completed.
