[Local radiation reactions and injuries in neutron and combined therapy of tumors using the U-120 cyclotron]. / Mestnye luchevye reaktsii i povrezhdeniia pri neitronnoi i sochetannoi terapii opukholei na tsiklotrone U-120.

Early local radiation reactions and radiation damage during fast neutron therapy of head and neck tumors were studied. The frequency of moist epidermitis in a radical course of neutron therapy was 33%, that in combined neutron and photon irradiation was 21%. Mucosal reactions were observed in 30-35% of the patients with tumors of the oral mucosa. The most frequent radiation damage in a long-term period were fibrotic changes of the skin and subcutaneous connective tissue.

The authors discuss some problems of preradiation preparation of patients with head and neck tumors for neutron teletherapy on the U-120 cyclotron of the Tomsk Polytechnical Institute in the Siberian Branch of the All-Union Cancer Research Center, AMS USSR. Some methods of the manufacture and employment technique of the fixing and forming devices for the optimization of neutron therapy are described.
