(3) Fast neutron radiotherapy for inoperable salivary gland tumors: Is it the treatment of choice? George Laramore, PhD MD 1987 Radiation Oncology Biologic Physics CONCLUSION: “I believe that one can indeed conclude that fast neutron radiotherapy is the present “treatment of choice” for inoperable malignant tumors of the salivary glands.” STATISTICAL CONCLUSIONS: “From multiple studies, 188 patients treated with photon or electron treatment had 52 patients achieve local control (28%), while 267 patients treated with neutrons had 182 patients achieve local control (68%). From a clinical trial jointly sponsored by the EORTC AND RTOG for 25 evaluable patients at one year the overall local/regional control rate was 53% for the neutron arm and 31% on the photon arm. The actuarial survival at 2 years was 55% for the neutron group and 13% for the photon group.”
