title: Aerosol orgotein (Ontosein) for the prevention of radiotherapy-induced adverse effects in head and neck cancer patients: a feasibility study.
abstract: Orgotein is an anti-inflammatory superoxide dismutase agent successfully used in treating several inflammatory diseases. It is also used in treating radiation-induced adverse effects in difference malignancies, notably breast, lung, bladder, prostate, cervix, and head and neck cancers. It is administered either topically or parenterally. To our knowledge, it has never been used before for prophylaxis of radiation-induced adverse effects or in aerosol form. Here we report on the results from a feasibility study on aerosol orgotein (Ontosein) for prevention of acute and deferred radiation-induced adverse effects in patients treated for head and neck malignancies. Our results show that aerosol orgotein administered before each radiation therapy session may impart some benefits in both incidence and severity of acute and deferred radiation-induced adverse effects in head and neck cancer patients, when compared with historical controls. In addition, aerosol orgotein administration is easy and convenient for both the patient and the radiotherapist.
