[Radiation-induced changes in normal tissues during neutron-photon therapy of recurrent cancer of the root of the tongue].

The paper is concerned with a case of a 2-year follow-up of a patient with recurrent cancer of the root of the tongue treated with fast neutrons on the Y-120 cyclotron. Medical history included a preoperative course of photon therapy at a dose of 40 Gy and operation. The total focal dose of fast neutrons of a repeated irradiation course was 11.2 Gy, that of photons--14 Gy corresponding to a total photon equivalent dose of 50 Gy. The authors provided the evidence of late radiation changes of the skin, temporomandibular articulation, pharynx, and the upper esophagus, and analyzed the causes of development of radiation complications.
