Neutron radiation therapy of parotid gland tumors.
A retrospective analysis of 9 patients treated with cyclotron fast neurons for tumors arising from the parotid gland is presented. In 3 of 4 patients who survived longer than 2 years, significant normal tissue damage occurred within the treatment volume. Five patients treated with neutrons or surgery plus neutrons for primary tumors stage III did not have a better prognosis with regard to survival than a comparable group of patients treated with conventional methods (i.e. surgery, photons, or a combination thereof). These results appear to be similar to those obtained for parotid tumors treated with neutrons in the early 1940's by STONE.
